Description

"STRUCTURE OF BUILDINGS FOR AGRICULTURAL SHEDS, ESPECIALLY"

The present invention is in the field of fixed construction elements and more particularly relates to a structure of buildings for agricultural sheds in particular. 5 Structures of buildings are known, the frame of which consists of an assembly of pieces of wood or metal, which support the various parts of the construction and which consist mainly of trusses and purlins. Farms, assemblies

- ^• - of triangular pieces of wood or metal placed from distance to distance to support the slopes of a roof, mainly comprise an entry constituting the base of the triangle, two crossbowmen constituting the two sides, and a punch constituting the height .

I ⁵ These farms are generally, with regard to agricultural sheds, separated by a distance approximately equal to 4.5 meters and connected together by purlins arranged parallel to the ground, fixed on the rafters and separated from others by an approximately equal distance

20 to 1.5 meters. The structures of sheds of this type are most often covered with galvanized, lacquered sheets or sheets of fiber cement.

And we know buildings constructed using the glulam technique, in which

^ 5 pieces of wood, of parallelepiped shape, of quite long length, are after soaking, simultaneously bent and sealed together, to form an arch.

However, these building structures require numerous and costly operations for their manufacture.

The present invention aims to provide a building structure, easy and quick design, and being of an advantageous cost compared to traditional building structures.

REPLACEMENT SHEET According to the present invention, a structure of buildings, in particular agricultural or industrial buildings, of the wooden frame type, the wooden elements of the frame possibly having been bent permanently, is generally characterized in that it is consisting of a plurality of arches, each arch being formed of at least one barrel, unique in the transverse dimension of the arch, permanently bent, the wood fibers being substantially continuous over the entire length said barrel; each hoop can be made up of a single and single barrel bent in a "semicircular arch", or be made up of two half-hoops placed end to end, each half hoop can comprise at least one straight part and at least one curved part, each half-arch being itself formed from, or from, a single barrel.

According to a first secondary characteristic, each half-arch is formed from a barrel split lengthwise into two equal halves, from which it follows that the wooden elements making up the arches have a cross section in the form of a semicircle.

Advantageously, the flat face resulting from the slitting forms the outer part of the hanger.

According to a second secondary characteristic, the barrels of two half-arches are shaped, at their upper end, in tenons, they meet tenon on tenon at this upper part and are solida¬ rised by a screw, passing through the two tenons, and a nut.

According to a third secondary characteristic, the arches are secured to each other, thanks to purlins fixed on the arches parallel to the longitudinal direction of the building and separated from each other by a distance approximately equal to 0.6 meters.

Advantageously, a cin- trée, with reinforcement function, is attached to each arch at the point of the curvature.

Advantageously also, the barrels penetrate at their lower end into a foundation disposed above a concrete die comprising an iron pin, penetrating into a pre-existing hollow of the barrel.

Preferably, said added cin¬ trée piece is also a piece of wood, and is bolted to the hoop. According to another embodiment, said added curved part is a metal part.

According to another form of realization, the structure, or framework, or frame is made up of a plurality of arches, each arch being formed of at least one barrel, unique in the transverse dimension of the arch, curved permanently, the wood fibers being substantially continuous over the entire length of said shaft, each arch having the shape of a half-circumference and at its ends provided with notches to be anchored in a foundation.

The present invention will be better understood and details will be apparent from the description which will be made of a particular embodiment, in relation to the figures of the appended plates in which:

Fig. 1 is a perspective illustration of the structure of buildings of the invention, in the position of use. Fig. 2 is a partial view, in section, of an arch of the building structure, put in place.

Fig. 3 is an element of detail in the previous figure, illustrating the means used to secure two barrels of the invention forming an arch.

REPLACEMENT SHEET Fig. 4 and fig.5 illustrate, in two sectional views, two embodiments of the invention.

Fig.6 illustrates an embodiment with a hoop, said semicircular single barrel.

In FIG. 1, a hangar slope 1, for example an agricultural hangar, consists on the one hand, of wooden elements 2, in the form of arches, placed from distance to distance (d) to support the slopes of the roof and sheets that will form the walls of the hangar, and on the other hand, 3 'wooden purlins, arranged parallel to the ground, connecting all the arches

2 between them.

These arches 2 consist of two half-arches (2 ', 2 ") having, in their middle, a curvature 4, or arch, so that they meet at their upper end (a'). lower end (b *), these arches (2) are secured to the ground, using conventional means which will be described later.

In FIG. 2, a half-arch 2 ′ of the building structure consists of a barrel

3 curved, approximately in the middle. This barrel 3 is formed by a straight part (b) and a curved part (a); the 3 "fibers of the wood are substantially continuous over the entire length of the half-arch 2 '. A curved element 5 is attached to each barrel 3, at the level of the curvature 4, follows its shape, and is intended to consolidate the structure by preventing the curvature 4 from increasing its radius; this curved element can be a piece of wood, curved independently of the barrel, but also a curved metal piece such as a U-shaped iron or half a round tube, or a pair of flat irons bent in their plane; these inserts are advantageously bolted to the poles. The lower part (b ') _f of each poles, penetrates into the ground and more precisely into a foundation 6, subsequently filled with concrete, and comprises a recess intended to accommodate an iron lug 8 of a concrete die 7. We will also note the notches made at the base of the arches to allow their anchoring in the concrete.

Wooden purlins 3 'connect, covering the arches 2; these purlins 3 'are separated from one another by a distance of approximately 60 centimeters on the curved portion (a) of the arches, and by a distance of approximately one meter on the straight portions (b). The radius of curvature RI, at the upper part of the straight part (a) is a few tens of centimeters and that R2 of the curved part (a) is several meters.

In Figure 3, the two barrels constituting the two half-hoops (2 ', 2 ") of the previous figure, were cut at their upper part so as to form a tenon (10,10'). Thus, the two barrels are joined, thanks to a screw 12 passing through the two tenons (10,10 ') and to a nut 11 fixing the tenons in this position This conformation of the ends of barrels 3, allows a good distribution of the loads, each of the barrels 3 being supported on the other and ensuring good maintenance of the structure.

In Figure 5, the barrel 3 has a circular section, and in Figure 4, it has a section having the shape of a semicircle. This last embodiment, resulting from the slitting along a barrel, provides better maintenance of the structure, the flat face 14 forming the outer part of the hanger.

In fig.6 each arch, full arch 20 is made of a barrel bent in half-cir¬ conference, whose notched ends 21,22 plunge into foundations 23,24 similar to those described above.

To achieve the bending of a hoop, each barrel 3, or half of barrel is put at soak in brine at 100 ° C for a period of about a few tens of minutes, then is shaped by applying it by force against an appropriate shape by allowing it to dry for about several days.

It will be noted that thanks to the long slitting of the barrels it is possible, on the one hand, to reduce the soaking time substantially, and on the other hand, to obtain smaller bending radii without damaging the spindle structure of the barrel.

Although a particular embodiment of the invention has been described and presented, it should be understood that it is not limited to this form and to these means, but that it is extends to all hangar structures having the general characteristics set out above.
