Description

DESCRIPTION

Light building structure

TECHNIQUE SECTOR

The present application refers to a structure that makes it possible to achieve a light, removable building, especially interesting as an elongated structure and that can serve, among other uses, as a hangar, greenhouse, micro or macro agricultural tunnels, sheds, roofs, agricultural windbreaks, roofs. for fruit trees, etc.

STATE OF THE TECHNIQUE

In the state of the art, greenhouses and other elongated structures are known to exist that have a series of porticos that support a series of panels, plates, or other elements to form an elongated building. These buildings have a large number of elements that often have to be shaped and lengthened on site, lengthening construction time and requiring labor and machinery.

The applicant does not know of any solution similar to the invention.

BRIEF EXPLANATION OF THE INVENTION

The invention refers to a light structure for buildings, according to the claims. Its achievements improve and solve the problems of the technique.

This system is an innovation to build structures based on simple, easily portable elements such as high resistance wires and cables, in different sections or diameters, and posts to create the porches or arches.

One of the main uses of these structures is to construct buildings for protected agriculture. It is important to understand what protected agriculture is, which greatly improves productivity, improves the quality of products, ensures harvests, achieving income security and lowering the costs of committed insurance, improves water consumption, advances dates of cultivation, reduces the use of pesticides, etc. Climatic risks are reduced to a minimum, whether due to rain, hail, frost, strong winds, etc. Therefore, a structure that is simple to build and has a low cost allows great agricultural advantages to be achieved.

The invention is more economical in all aspects: materials, machinery, labor, without the need to punish quality and the objective pursued, which is to have a resistant and durable structure.

To this end, the light building structure is formed by a series of parallel and facing porches, comprising at least two extreme porticos. These frames are linked by a series of tensioned cables that make up the contour of the structure, using, in the most preferred solution, a galvanized steel cable or wire that has optimal elasticity. Advantageously, wires are added transversely between the cables. These wires are arranged in an “S” shape, so that they are attached to a section of each cable to which they are fixed, greatly increasing the robustness of the grid wall thus formed. The connection to the section can be continuous (for example, rolling) or at several points.

The rest of the report describes other particular realizations.

MODES OF EMBODIMENT OF THE INVENTION

Next, a way of carrying out the invention is briefly described, as an illustrative and non-limiting example of it.

Figures 1-3 show an embodiment of the structure formed by a series of parallel frames (1,2), and a series of cables (3) joined to all the frames (1,2). The porticos (1,2) are divided into two extreme porticos (1,2), which may have windows, doors and other accessories and which will have one side facing the outside of the building, and middle porticos (2). The number of middle frames (2) depends on the building being constructed. In short buildings, the middle porches can be ignored (2). All the frames (1,2) represented have the same external shape so that the cables (3) arranged between them are fully parallel. They can also have accessories that are outside the area covered by the cables (3).

It can be seen that the middle porches (2) represented are diaphanous, so as not to affect the useful interior space. However, they can generate partitions if desired.

The end frames (1) are arranged with braces (4) that resist the mechanical stress made by the cables (3). These are tensioned, for example to 1000 pounds of tension (453.6 kg). If the building constructed is large, such as a hangar, stronger cables (3) and higher tension may be necessary.

Between the cables (3) there is a series of wires (5) that are tied to form an “S” of square sections (figure 4). Thus, each wire (5) is joined, usually by coiling, to a section of cable (3) before passing to the adjacent cable (3). This solution increases the resistance of the structure, forming a whole by joining the cables (3) together. The wires (5) can be placed every little distance, for example 0.5-2 meters, according to the needs of the structure. The wire (5) will generally have a larger section than the cable (3) and will tend to maintain the shape in which it has been arranged.

For construction, the frames (1,2) are arranged correctly fixed to the ground, and cables (3) are laid from one side to the other, passing through all the frames (1,2) and ensuring that it is tensioned (figure 1 ). The cables (3) can come out from the outside of the end frames (1) or partially or completely run through them to reach a more accessible anchoring point. Once the cables (3) are arranged, the wires (5) are placed (figure 2).

Once the structure is built, it can be covered with tarps, fabrics, plastic sheets, irons... without the chosen method or the covered surface being relevant to the invention (figure 3).

Figure 5 shows a way to place the cables (3) in the end frames (1). Part of some “clips” or grips (6) that hold the free end of the cable (3) by means of a body with a larger diameter than a limiter, in this case square, fixed to the end porch (1).

Figure 6 shows a schematic side view of an example of the structure with a single middle porch (2). It can be seen that the frames (1,2) are adequately fixed to the ground, using footings or another similar method, and the presence of the braces (4) or guy ropes, which have tensioners (7).

This way of building structures is very versatile, allowing different designs, for example varying the shape of the porticos (1,2), their perimeter.
