Abstract

A structural mesh for floors and pavements comprises two types of rods. The first rods are rods with zig-zag bends, placed vertically, and the second rods are straight, of different length than the first and placed in a vertical way. These second rods are joined by welding to each vertex of the rods that go in a zig-zag, one at the top and the other at the bottom. The second straight rods comprise different degrees of inclination of the zig-zag rods. Some of the second straight rods go in the upper part and others in the lower part and go in the opposite direction from each other, being in the shape of a rhombus, when viewed from the ground. The second rods are within a concrete slab integrated with the first zig-zag rods, the second straight rods, the upper and lower linings, and the saddles.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a National Stage of International Application No. PCT/IB2019/057223, filed Aug. 27, 2019, which in turn claims the benefit of Mexican Patent Application MX/a/2018/010739, filed Sep. 6, 2018. The entire disclosures of the above applications are hereby incorporated herein by reference.

FIELD OF THE INVENTION

The present invention involves the improved function of reinforced steel construction rods employed and integrated to this type of arrangement, due to their zig-zag design and geometric distribution that are used in floor slabs and hydraulic concrete pavements, this geometric design and arrangement is very different to those commonly known in the state of the art and those currently used in the market.

BACKGROUND OF THE INVENTION

The traditional design of reinforcing steel rods, for floors or concrete slabs, is normally in the form of a square grid with different distances and diameters of the rods, these are used to reinforce hydraulic concrete floors and pavements and can be available with one or two grills that are integrated into the slabs.
These traditional reinforcements and designs are to avoid the various problems that normally occur in floors and pavements, which are cracks, fissures, warping and others.
There are other methods and design alternatives to avoid the various problems of floors and pavements such as: post-tensioned floors, low-shrinkage concrete, double reinforcing bars of steel rods, synthetic or steel fibers, and other additives, all of which are very expensive.

OBJECT OF THE INVENTION

The objective of the present invention of a particular structural mesh for floors and pavements reinforced with zig-zag rods is to provide a design that works on the transmission and distribution of loads that are absorbed by the mesh itself in an integral way with the hydraulic concrete. This is due to its integration and modulation in its geometric design, being more efficient for the different problems that arise in the various elements of slabs, floors and pavements.
Further areas of applicability will become apparent from the description provided herein. It should be understood that the description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description and appended drawings describe and illustrate various embodiments of the invention. The description and drawings serve to enable one skilled in the art to make and use the invention, and are not intended to limit the scope of the invention in any manner. In respect of the methods disclosed, the steps presented are exemplary in nature, and thus, the order of the steps is not necessary or critical unless otherwise disclosed.
The structural mesh for floors and pavements of the present invention comprises zig-zag rods along the entire length of the slab, with zig-zag bends, placed vertically. The length of these depends on the design and the dimension of the slab. The height and bends of the rods depend on the thickness of the slab and this, in turn, depends on the design and assembly, as shown in FIG. 1 of the zig-zag rod (1).
The second rods used in this design are straight, of different lengths, and placed horizontally. These are joined through welding each vertex of the rods that go in zig-zag, one in the upper part (2) and another in the lower part (3) as shown in FIG. 2.
The separation between each longitudinal zig-zag rod, which goes across the width of the slab between each of these, is related to the height of the zig-zag rod, that is, if “X” is the height of the zig-zag rod, the separation between them is “2X” or according to the design and they are placed in a vertical position, joined with the straight rods, one at the bottom and the other at the top, as mentioned in the previous paragraph and is depicted in FIG. 3.
The dimensions and the number of rods to be used across the width of the slab are a function of the thickness of the slab and its dimension.
On the other hand, the rods mentioned above that join each vertex of the rods that go in a zig-zag, are straight and of different size. These will go to different degrees of inclination of the rods that go along the zig-zag slab. Some go in the upper part (2) and the others in the lower part (3) and go in the opposite direction from each other, being in the shape of a rhombus, seeing them in a plant position. These rods are welded at each vertex with the zig-zag rods, joining them together as shown in FIGS. 4A and 4B.
In addition, the zig-zag shaped rods are inserted in their starting position of the assembly, that is, if the vertex of the first rod starts at the bottom * (I), the second rod line will go on the top. ** (S), the third will be in the lower position * (I) and so on until it covers the width of the slab, which depends on the thickness or design of the concrete slab, as shown in FIG. 6.
Integration of the Assembly of the Invention
By integrating the zig-zag rods that go along the slab, with the union of the straight rods, some in the upper part and others in the lower part as mentioned in previous paragraphs, they are integrating the assembly and with this, the origin of the invention of the design of the structural mesh for floors and pavements reinforced with zig-zag rods.
The slabs, depending on the thickness of their design, will have a lower and upper coating according to the design. In the lower part, saddles will be used that will serve to mount the mesh and have the separation with the base of the floor to be covered, the saddles (5) will be placed according to the specifications of the saddles (5) to support the different operating loads to which they will be subjected and they will also be placed in both directions of the mesh to maintain its uniformity and level, thus avoiding possible deformation, thereby maintaining the level of the mesh design and the slab.
In the upper part a coating (4) is recommended according to its design, as shown in FIG. 7.
As an example and more details, some examples of the various thicknesses of the most commercial slabs used in the market are attached, which are: 15, 20, 25, and 30 cm. or more. These at the time can be designed with any other thickness, distance and angle of the zig-zag rod, always retaking the original design of the invention, maintaining the design of the same.

TABLE 1

Thicknesses of the most commercial slabs used in the
market, which are: 15, 20, 25, and 30 cm or more.

Slab Thickness	Height	Base	Section
cm	cm	cm	cm
A	B	C	D

15	X	Y	Z
20	X*	Y*	Z*
25	X**	Y**	Z**
30	X***	Y***	Z***

On the other hand, the diameter of the rod to be used can be varied and this will depend on the design load to which it will be subjected, always maintaining the design of the mesh of this invention.
The union of the slabs or modules between each structural mesh for floors and pavements reinforced with zig-zag rods, for the transmission of loads to which it will be subjected and the integration between them, dowels and tie bars are used, which are usually used for the transmission of loads and the union of these. The dimensions and characteristics of these will be according to the thickness of the slab and the service load of its design as shown in FIG. 8 and Table 1.
On the other hand, the ready-mixed concrete to be used for this design must comply with the quality required for the design of the slabs, as well as with the regulations of the product specified according to design.
Advantages
The main advantage of the structural mesh for floors and pavements reinforced with zig-zag rods is the reduction of cracks, fissures and warping that slabs normally present. A factor in favor of the invention is the cost-benefit of its maintenance, as well as the maintenance of the various equipment and vehicles that travel on the floors or pavements and that will have a lower maintenance cost in general.
In addition, it provides increased safety in the transit of forklifts on industrial floors or any other type of service, offering the benefit of safety with preventive maintenance to concrete slabs and floors with the reinforcement of the mesh of this invention.
Based on the design of the mesh of this invention, the various static and mechanical loads to which the slabs are subjected are dissipated and the steel works in an integral way, absorbing and transmitting the loads to the entire structure of the floor or pavement, thus having a greater load and support area, with greater efficiency and avoiding the warping and cracking that they normally present. Also, it maintains the same level between slabs and thereby a greater flatness of the floors and pavements.
While certain representative embodiments and details have been shown for purposes of illustrating the invention, it will be apparent to those skilled in the art that various changes may be made without departing from the scope of the disclosure, which is further described in the following appended claims.
