CONSTRUCTION


Metal structures constitute the most widely used construction system in most countries. It is ideal given its malleability, hardness and resistance features. Its structural efficiency is very high, due to the fact of being produced in sections with the most convenient shape so as to withstand flexion and compression. At Exafan, we consider that the most convenient systems for our designs are the ones named type IPE and the ones named type C, given that their performance is perfectly linear and elastic, which makes the structure performance in relationship with this material very predictable. The material high ductility enables to redistribute an effort concentration.

STRUCTURE


01.01.01.- Metal structures

Building structure based on a steel structure with a European standard metal framing type IPE; it was chosen thanks to its flexibility, quality warranty, mechanic resistance and adaptability to the Exafan Company´s customized building designs. Each building is analyzed on an individual basis, which allows determining the section for each element, such as: pillars, knives, belts, and reinforcements. 

IPE

The structure is made of steel profiles type IPE, screwed in on sight and with galvanized beams type “C”. The protection concerning the beam and pillar corrosion is made through a deep hot galvanized process; the lintel protection is made through a grey chlorine rubber primer.

Bearing in mind all these aspects, exclusive for each project, we manage to calculate and optimize the metal structure according to the European regulation Eurocode 3. Metal structure project. A steel quality of S275JR is used according to the UNE EN 10025:1994 standard. Hot laminated products made of non – alloy steel, for metal constructions aimed at general use.

We bear in mind all the loads corresponding to the internal equipment and its position in order to adequate the metal structure to these elements so as to achieve a complete and functional building design plus the equipment. Feeding systems, as well as the water supply systems, they both hang on the structure given the fact that they play a major role in the load supported by the structure.

Structural calculations are made according to the records gathered in the construction zone, the basic wind load is also determined, as well as we consider the different categories of the ground – vegetation area, possible isolated obstacles (trees, buildings) separation between one another -, according to the Eurocode 1. Project bases and actions on the structures. We also consider the dead loads corresponding to the building construction elements themselves (corrugated roof sheet, insulating sheets,…) and the metal structure weight + the metal belts.

• The building slope is determined according to the poultry housing internal equipment, with the purpose of facilitating, optimizing, and improving their ventilation systems.

• The links between the elements are designed to be screwed in and assembled on sight, which guarantees the correct connection between them, it also prevents any welding procedure to carry out on sight without the convenient safety measures. All these linking elements (screws, nuts, washers,..) have been calculated according to the DIN standard (German National Standardization Organism), it is a European standard. Likewise, their quality type is of 8.8 according to the UNE EN 70462:2012. Screws made of stainless steel and non – ferrous metal screws.

01.01.02.- Metal structures “C” type

Detachable modular structure “Meccano” type, flexible and adaptable, designed to be transported occupying a smaller area; this makes us tremendously competitive for facilities where it is required to transport material to a long distance. 

The building design system by means of the assembly system kit type not only makes its transportation easier, but also thanks to its very much analyzed assembly procedure of the different structure parts, human errors are minimized and the structure assembly process is enormously simplified.

The fodder transportation system, feeders, as well as the water transportation system hang from the structure.

The structure “C” type is formed by galvanized profiles conformed under cold conditions of C or Z type. 100% of the structure is assembled by means of hot galvanized screwed – in links. This structured stands out thanks to its galvanized finishing, which allows a special protection before the environmental corrosion provided its lightness and easy transportation in containers, a perfect economic solution for markets abroad.

Identification of the different elements for their later and easier assembly. The structure assembly process is made on sight, by means of a simple system of links using screws allowing an easy, quick and safe assembly process; this avoids any uncontrolled welding process on sight.

Light and resistant Profile C, use of light materials with forms designed to offer a higher resistance performance by using the lowest quantity of materials possible; this allows reducing costs in terms of product and transportation.

• Hot galvanized recover (from 275 g/m2 to 600 g/m2) • Without any snow loading limit. • Adaptability of the structure design to the conditions on the ground where to install. • Delivery term guaranteed.

The assembly process system on – sight avoids any unnecessary welding.


Poultry farms must have an adequate thermal insulating system in order to make the breeding process in an efficient and profitable way. A correct insulation as well as a good environmental management control system is critical in terms of cost reduction and improvement of the production index.

INSULATION


01.02.-

Insulation

In order to efficiently save power inside the farming buildings, we must monitor and correctly check the environmental control system, something we are truly specialist at Exafan; however, in order for this practice to be really efficient, it is essential to begin by correctly insulating all the elements included in the buildings. Roofs, internal insulation, lateral enclosures, and mobile accesses, are the elements providing the building with the convenient insulation level required so as to maximize the control process. The global insulation level of a building is defined by the weighted average coefficient of all the enclosures surrounding the building. The turnkey project solution offered by EXAFAN makes such insulating level unbeatable, given its concern care regarding the election of the materials, their quality and added value given the company´s experience as a leader in the construction sector of farming buildings. Exafan supplies all the external equipment required according to the highest insulation standards, elements such as air extractors, air inlets and building access gates have been designed to successfully face the most extreme environmental conditions possible.

Insulating a farming building is a requirement because of the following reasons: - In order to efficiently contribute for an energy saving program. - Higher animal comfort. - Building better maintenance. - Better environmental quality. - Less fodder consumption.

Insulation for the roof with a simple sheet, air chamber with a glass wool, and a false ceiling made of a panel sheet with an insulating nucleus PUR or PIR.

Materials used for a correct insulation Polyurethane: It is an insulating synthetic material for different construction applications; its high insulating power as well as extreme lightness, makes it an ideal material as an insulating nucleus for the enclosures of the roof or perimeters. Very low thermal conductivity synthetic material; it is the lowest one considering all the insulating materials. This is important given that it allows a higher insulation degree with less thick material Polyisocyanurate: the combination of the polyol and isocyanate elements gives some very specific features to the material due to the different chemical structures. The insulating PIR sheets are used given their higher thermal stability features and resistance regarding fire. Rock wool: or glass fiber, it is a material made of volcanic rock. It is mainly used as a thermal insulator as well as passive protection device against building fire, due to its fibrous multidirectional structure, which allows storing relatively immobile air inside. The structure made of rock wool includes some dry and stable air inside, therefore it works as an obstacle to the transfer of heat, insulating against low and high temperature.

Air chamber

High volume air chamber contributing with a better insulating thermo – regulating action as well as decrease of the quantity of “superfluous� air to heat.


The metal roof is the most delicate part of any farming construction building subject to a strong loss of energy in winter and very exposed to sun radiation in summer. The design and installation of the metal roof require high degrees of reliability and endurance. A warranty that EXAFAN confirms on the basis of its technical know – how acquired in the industrial construction sector for many years. We apply our demanding quality values along with an experience in the treatment of steel, sheets, sandwich panel and waterproofing. We offer different kinds of roof for farming buildings.

In order to meet the highest quality standards, Exafan offers different solutions regarding the building roof and insulation while meeting a large proportion of the requirements set up by our customers. Most of the building calorific loss takes place through the roof, thereafter, the relevance of the whole set shaped by the external roof and the false ceiling. The roof is in charge of removing out the environmental elements such as snow and water, whereby the calculation of the slope is made with the purpose of avoiding any filtration, and always bearing in mind factors such as the climate zone where we are positioned.

The building roof is a gabled roof type. The roof parts are fixed to the belts by means of the galvanized self – drilling screws supplied with also galvanized washers in an armed bituminous product. The material used complies with the corresponding current regulation. We always bear in mind the manufacturer´s specifications, such as the separation between the belts and the minimal lap.

For a better protection of the facades, the tilted roof is extended further on the façade plan by shaping an eave.

The building roof insulation does not only consist on the upper part, but also on the lower part, for such purposes, Exafan has developed a kind of under roof insulation providing the best results at a better cost / benefit relationship by using a rigid panel foam made of polyurethane (PUR) covered on both sides by a complex multi – layer made of aluminum – kraft. Among its main features, let´s underline its high thermal resistance enabling to use a lower insulating panel thickness, rigidity and lightness facilitating its manipulation and installation. The panel PUR high insulating power allows ensuring a high thermal comfort once installed.

The election of the poultry farm location is subject to a series of conditions: regulation, infrastructures (access, water, and light), elimination of the waste, etc. In general, we should search for a healthy land, protected from strong wind, but sufficiently airy, dry and well drained, this avoids additional problems since the very beginning of the installation. In order to avoid such negative influences on the calculations of our ventilation system, we recommend taking into account some natural windbreak barriers with the purpose of avoiding a dependency on them. Exafan provides to its rooms with a lateral gable that tries to minimize the adverse wind effects on the ventilation calculations.

Light installation made including traditional fluorescents with an electric power consumption of 1.608 W.

The different kinds of lightning offered by Exafan, has as main purpose to be able to favor the animal growth. At Exafan, we build farms without light inlets with the purpose of being able to control the light intensity inside the room. Therefore, with the different light programs available or by controlling the light intensity, we may promote the chick activity and stimulate the access periods to the fodder and water as well as the periods of inactivity in order to reduce the animal aggressiveness, its level of anxiety, or even unnecessary expenses in terms of power consumption. By doing this, we achieve heavier animals in the slaughterhouse and a better feeding conversion index, due to the power saving achieved because of a lower activity and higher quality of the channels of the animals as well as fewer injuries due to a more docile behavior.

The use of water meters is an excellent way to estimate the fodder consumption.

Ref. 07120 Contador de agua Water meter (1 litre / push)

Changes in the water consumption level must be investigated because this may indicate a water leaking problem, an animal health issue, or a problem related with the poultry feeding process. Usually, a low water consumption level is an indication of a certain problem.

Independent water registration to manage the water consumption level of the animals

Ref. 07300 CA1 Individual weighing pan

Climate controller associated to the water meter, supplied at 12 v or 220 v, it allows us to check and record the daily water consumption of the animals, it allows configuring the alarms for an early warning with the purpose of detecting and correcting any anomaly it might take place (maximum or minimum consumption).

A continuous control of the animal weight is required to assess the growth process of the animals, the sooner we have this information, the sooner we will be able to implement a corrective measure.

Ref. 07095 ESPAN- PAN Central weighing unit, autonomous

Ref. 07020 UCP 210 Central weighing unit, autonomous Ref. 07070 UCP 110 Central weighing unit, dependent of an EHG

The system UCP – 400 used to control the weighing process is an important management tool, this way, you may obtain the information of the real animal weight live, as well as the water consumption. EXAFAN weighing pans have been developed to obtain the largest number of weighing processes possible, even when the animals are in their last breeding days and their mobility is scarce. An excessive or insufficient weight has a negative effect on a successful production rate as well as on the performance potential of the animals.

Air inlets


02.02.- Air inlet control

The air inlets made of polyurethane by the Exafan Company on top of directing the airflow at your convenience; they provide with a perfect insulation level and avoid the intake of parasite elements that would increase the heating consumption and affect the ventilation system, and so would distort the air circuits projected, and therefore create wrong ventilated areas.

Winter

Summer

Summer: with more than a 57% opening degree, the air flow is divided into two proportionate and progressive ways; it is very beneficial in summer, since the higher temperature, the largest the air flow is directed towards the area where the animals are located; this improves the environment and delays the set in motion of the cooling systems. Winter: with less than a 57% opening degree, the air flow is directed towards the upper part and get mixed with the already existing one in order avoid the fall of cold air on the animals, it is ideal for cold seasons.

Veas: the synergy level generated when widening the air inlets specifically designed by Exafan is essential at the time of achieving the required precision level, such level is not possible to achieve if another kind of more generic air inlet is used.

Feeding systems


02.08.- Feeding systems

At Exafan, we consider the choice for the kind of feeder to use according to the kind of poultry as important as the space for feeding available (it is absolutely critical). If the space for feeding is insufficient, the growth rate will decrease and the uniformity of the lot will be seriously affected. The distribution of the fodder and proximity of the feeders to the animals are key factors that at Exafan we bear pretty much in mind if we wish to achieve the programmed feed consumption rate. Exafan´s support even gets to the point of advising the producers on

The corporal weight control of the poultry is achieved by continuously adjusting the quantity of feed supplied to the chicks while taking the real weight of the poultry and their relationship with the ideal curve weight as a reference.

At Exafan, we consider that a correct choice regarding the feeders is as important as their proper management, the feeders supplied by the Exafan Company are semi – automatic and can be regulated in terms of their height in order to supply the adequate quantity of fodder according to the animal age.

Poultry feeders The feeder Leo complies with the goal of feeding the chicks since the first day. Thanks to the pan height only 7,5 cm high, the chick one day old is capable of feeding itself at its own will.

The analyzed design of the feeder Leo prevents the chick from getting inside the pan. It teaches the chick how to learn to eat from outside through the contention rings.

The Eos is the new and innovating feeder for the broiler industry. The EOS has been analyzed in detail to get perfectly adapted to the animal requirements, since the first days until the cycle end. During the first days, the pan remains on the floor. The flat bottom (only 55m high) makes the access to the food by the chicks very easy. The central bell favors the feed to

remain clean and with no risk of getting polluted. The quantity of feed getting to the pans decreases according to the animal age, thanks to an innovating system of rotating openings.

The Lyra is a multipurpose feeder including a design guaranteeing an excellent result with broilers, turkeys, laying hens, etc. Thanks to the feeder Lyra, changing the kind of animal, race or cycle period is no problem any more.

Regarding the days 55/60 for the turkeys and 40/45 for the ducks, a collar is available to be assembled on the pan external border.

The Superpito is designed to accompany the turkey during its growth since the very first day. It has two interchangeable pans analyzed for the different stages of the breeding period. The Superpito feeder is dimensioned to feed according to the turkey wish since the very first days preventing it from getting inside. It is efficient and economic on top of very easily installable. The Atos feeder. Here, hens are particularly aggressive and vigorous.

The air distribution system is an ideal system for breeding fowls of chicks experiencing a feeding restriction (they only eat once a day and little quantity), since at the time of distributing the feed uniformly through the entire surface of the shed, animals get access to the feed without competing against the others. Fowls are bred more uniformly and the mortality level decreases. The hopper does not destroy the granulated feed, that is why the hen finds it easily, and the distribution system in rain mode does not damage the eyes of the animals. The number of animals per square meter is higher as there is no obstruction on the ground, which considerably improves the animal welfare.

The entire feed distribution system as well as the heavy air distribution hoppers hang from the room metal structure, that is why the option for a productive unit supplied by the Exafan Company makes it the most convenient alternative.

Basically, water is used in poultry farms for the animal to drink as well the cooling and cleaning process systems. In every new intensive exploitation project, one of the sections we must take care of is the accumulation, storing and distribution of water

At Exafan, we also take care of the animals having a comfortable access to the drinkers, which must be well located and accessible at a distance below 1 meter during the first life stage. Water must be fresh and good bacteriological quality as well as chemically treated. The supply of clean and fresh water with adequate flow is fundamental for the poultry production. Without an adequate water consumption level, the fodder consumption will decrease and the general performance of the animals compromised.

At Exafan, we consider that water is essential for the development and welfare of the animals; they must have convenient access to it in order to meet their needs and avoid liquid feces and therefore humidity on the bed.

Nests do not damage the eggs and are stored safely and clean. The versatility of the laying nests AVIO enable them to position back to back along the length of the farm. They also enable the existence of a certain space between the laying nests allowing the animal free circulation. The hens may enter through any side of the block of nests. Eggs are laid on a special synthetic coating and roll very over easily on the central collection channel. Each nest floor is galvanized with a mesh and a drilled

blanket �Astrturl�, both sides can be easily removed for their cleaning. We may avoid the hens to remain on the nests too long. Inside each nest, there is a mesh panel, which can be advanced automatically for the hens to Pag.-98

move outside the laying nest. This way is possible to keep the nest empty. The eggs pass through a wide and rigid belt made of polypropylene and arrive healthy and safe to the designed place as the collection point. The belt speed can be electronically ad-
