STRUCTURAL DEVICE FOR SHAPING

CONSTRUCTION"

[001] The present invention is developed for the field of construction. Specifically, the present invention discloses a structural device which constitutes an innovative invention for forming building slabs replacing conventional floor slabs or slabs which can be installed simply. in any type of construction and has characteristics of flexural and tensile strength, which gives seismic strength advantages to the constructions.

TECHNICAL STATE

In the field of building construction, some structures are required to form their roofs and slabs, which provide stiffness, strength and help maintain the balance of the structures. For example, if slabs are required, they have the function of dividing a structure into a large number of equidistant structural elements (called beams), so that each resist a portion of the total load. Thus, the slabs need to use these structural devices to conform the slabs. In such a case, both the modulation and the gap between the beam supports will be the factors that determine the section of the adopted structural devices. Therefore, in general, the beams are oriented in the direction that generates the shortest distance between the supports, such that the structural device has the smallest possible section.

In the prior art, some slab forming construction systems are known which are applicable to constructions for reinforcing the slabs, floor slabs or roofs. In particular, the conventional system for forming boards or slabs that functions as slabs and which requires a large amount of structural elements, as well as a larger amount of support material such as concrete or cement, is well-known, and therefore the workers are installed. It requires more time and increases operating costs. Additionally, these systems still have some disadvantages of seismic strength and flexural strength that are essential for the construction system.

Accordingly, there still exists in the state of the art the urgent need for an innovative alternative for forming slabs or floor slabs that improves the drawbacks and overcomes the disadvantages of conventional systems based on. planks, by reducing operating costs, the number of workers required, easily available, economical and which additionally significantly improves the flexural strength and seismic strength properties of the constructions.

[006] The present invention offers a first object corresponding to a structural device for forming slabs or floor slabs, characterized by an elongated flat base (1) which is bent at its inward ends to form two wing structures (2). ), which subsequently extend upwards into two side walls (3); such sidewalls (3) extend to two upper ends (4), which correspond to U-shaped folded ends; wherein such elongate flat base (1) has a series of internal slots (1.1) which run completely through the body of the elongate flat base () and each of the side walls (3) has a series of slots (3.1) that run through it. such side walls (3) along their longitudinal direction; and wherein each of the upper extremities (4) has a series of internal slits (4.1) which run completely through the body of said upper extremities (4).

In a preferred embodiment of the present invention, the structural device is characterized by the base (1) having from one to ten internal slots (.1).

In another embodiment of the present invention, the structural device is characterized by the base (1) having three internal slots (1.1).

In another preferred embodiment of the present invention, the structural device is characterized by the base (2) having an internal slot (1.1).

In another preferred embodiment of the present invention, the structural device is characterized by the base (1) which is completely smooth and has no internal cracks.

[010] In another preferred embodiment of the present invention, the structural device is characterized in that each side wall (3) has from one to ten slots

(3.1).

In another preferred embodiment of the present invention, the structural device is characterized in that each of the side walls (3) has three slots (3.1).

[012] In another preferred embodiment of the present invention, the structural device is characterized in that each of the side walls (3) has a slot (3.1). 1013] In another preferred embodiment of the present invention, the structural device is characterized in that each side wall is completely smooth and has no cracks (3.1).

In another preferred embodiment of the present invention, the structural device is characterized in that each of the upper ends (4) has from one to four slots (4.1).

[015] In another preferred embodiment of the present invention, the structural device is characterized in that each of the upper ends (4) is completely smooth and has no cracks (4.1).

[016] In another preferred embodiment of the present invention, the structural device is characterized in that any of the slots (1.1), (3.1) and (4.1) have straight, rounded, semi-rounded, triangular, polyhedral edges.

In another preferred embodiment of the present invention, the structural device is characterized by being made of steel, galvanized steel, cold rolled steel (commonly known as Cold Rolled (CR) or hot rolled steel (commonly known as Hot rolled). HR)) or aluminum.

The structural device of the present invention has a completely specific design which, when coupled with other simple structural components, significantly improves the properties of seismic strength and flexural strength in any construction incorporating it, either with slab or roof.

{019 "] Its specific design follows an elongated element with two extreme sides, shaped like a rectangular flat base with extreme side edges folded inwardly like wings. Such wings extend laterally perpendicularly upwards, forming the sidewalls, which continue to extend to form two corresponding upper ends for each wall, configured as inverted U-shaped folded ends thereof, as illustrated in Figures 1 and 2.

[020] A characteristic feature of the structural device of the present invention is its ability to combine completely flat or slotted surfaces of the base, the walls or the lateral extremities, where such slots may have edges of different geometric shapes, and run completely through the body of the body. base, the walls or the upper extremes, as illustrated schematically in the figures. This innovative combination of the structural device of the present invention makes it possible to have superior flexural strength properties, which makes it an efficient alternative to replace traditional roofing, slab or floor slab forming systems.

[021] The above is possible due to the structural device being coupled together with other structural components to conform the roofs, slabs or floor slabs, according to the specifications of the area required by the users. Thus, the structural device of the present invention is arranged longitudinally in the form of neat rows with spaces between them for adjusting styrofoam rectangular elements or tiles on their wing portions such that they are coupled behind one another. another about the structural devices of the present invention.

It is necessary to take into consideration for the arrangement of the structural devices of the present invention that both the modulation and the light between beam supports will be the determining factors for the section of the adopted structural devices. Therefore, in general, the beams are oriented in the direction that generates the shortest distance between supports, such that the structural device has the smallest possible section. Once this structure is formed between the structural devices of the present invention and the rectangular support elements, the worker proceeds to have an additional support element formed by bars or steel mesh. Finally, the worker must pour concrete or cement over the upper portion of this support device-reinforcement until it covers the entire area and allows it to dry. This dry system makes it possible to form a roof, building slab or floor slab with excellent seismic and flexural strength properties, which replaces conventional building systems.

The upper portions of the structural device of the present invention have various configurations in their design, where material may enter the said device. These modifications allow for various border shapes, which can be straight, triangulated, semi-straight, semi-oval, semi-ellipse, polyhedral, wavy, among others, as shown in the flat images of the figures. [025] In a specific and characteristic design of the structural device, the base may be completely smooth, while the walls may have between one and ten slits; or the base may include a slot, with two slotted sidewalls. Similarly, the edges of the upper ends (4) which are folded upside down may have one or more slits, while the walls may be smooth and the base may have one or more slits. An experienced person will understand that any base, walls or ends may or may not include more slots, and the resulting combination of these slots in the base, walls or upper ends will depend on market needs or the required technical specifications.

These cracks along the walls, the upper portions and the base of the structural device of the present invention are largely responsible for the improved seismic strength and flexural strength properties as their specific arrangement provides increased rigidity and resistance to structural device of the present invention.

[027] Additionally, the extremities of the upper edges (4) may have various shapes on their edges to meet market needs. [028] For example, depending on the number of slots present or not, these edges of the upper extremities may be of any of the following forms: straight, rounded, triangular, trapezoidal, wavy, oval, semi-ellipse, or semi-rounded edges, as illustrated in the Figures. However, a person skilled in this subject will understand that various shapes are possible for these upper extremity edges (4). In any case, this person will understand that for practical purposes, the upper end of the structural device of the present invention should have an opening allowing the material to enter, which may be a mixture of cement, concrete, concrete, among others. Thus, in the case of straight edges at the upper ends (4), the skilled person will know that the distance between such edges may vary so that the aperture is larger or smaller.

Technical specifications

[029] The structural device related to the present invention is specifically configured to achieve the required seismic resistance and flexural strength. [030] The structural device of the present invention can be made of various materials that are commonly used in the mechanical sector, such as steel, galvanized steel, cold rolled steel (commonly known as Cold Rolled (CR) or hot rolled steel (commonly Hot rolled (HR)) or aluminum, etc. However, the experienced person will understand that it is possible to use another variety of materials to manufacture such components, as long as the expected results to improve seismic and bending strength can be achieved. of the constructions incorporating the structural device.

With respect to the weights and measurements of the structural device of the present invention, the skilled person will understand that this device can be manufactured to fit and comply with the standard standards established in accordance with each local building field legislation. Thus, while the structural device of the present invention can be manufactured to fit market needs, the skilled person will understand that it is possible to make the necessary modifications in weight, measurements and materials, provided they maintain the required technical specifications for the device. of the present invention improved seismic resistance and flexural strength.

This is how an experienced person interested in manufacturing the structural device of the present invention can design it into a calculation table in which the device specifications are standardized from different variables, including weight, dimensions, load. maximum supported (flexural strength), seismic resistance, among others. From these specifications, the skilled person can combine such variables and perform the calculations necessary to determine the technical specifications of the structural device resulting from the present invention, with improved seismic strength and flexural strength properties.

However, by way of illustrative example, the table below shows some typical technical specifications for a structural device such as the present invention:

Height 7-10 cm Weight 3.00 - 4.00 Kg

The foregoing dimensions are not restricted to the structural device of the present invention, but are illustrative of some commonly required measures in the structural device market and, therefore, may vary according to user or market requirements.

Experimental Trials

[035] An illustrative structural device of the present invention having straight upper edges and nine slots in each of the side walls has been subjected to various laboratory tests to measure its flexural strength or maximum supported load. These tests have been performed by several certified laboratories accredited in the field of materials. Following are the results of two of these experimental assays, in the following tables:

[039] The test corresponds to a FLEXION TEST carried out following the procedure described in Colombian Technical Standard NTC 3353-97.

The above results strongly demonstrate that the structural device of the present invention has excellent tensile strength properties. For example, the seven-slotted device on the sidewalls and flat base with straight edges has significantly higher bending strength as it can withstand a maximum load of 15.99 kN (15991, 69 N, 1630, 7 kgf). On the other hand, the device with nine slits on the sidewalls and flat base with straight edges also has significantly higher flexural strength as it can withstand a maximum load of 16.89 kN (16,895 N, 1723 kgf ). These experimental results demonstrate that the structural device of the present invention is absolutely ideal for forming slabs or floor slabs in various constructions.
