Grill for localization of material

 

The invention relates to the construction and, in particular, can be used in the construction of the road base service roads, as well as for hardening and protection against erosion of soil slopes, canals, veneers and hydraulic structures. Grill for localization of the material is made of flexible strips set on edge and connected to each other through the gaps of the joints, the parts between which the tensile form the walls of the cell volume of the honeycomb structure. What's new is that the edges of the strips facing the ground, made located at the midpoints of the walls of the cells or at the seams connecting the two adjacent bands, triangular, or oval, or trapezoidal, or rectangular protrusions with a height, component 0,2-1,5 width of the flexible strip and the tabs on the extreme fringes made higher than the protrusions on the inner lanes. The technical result of the invention is to reduce the complexity and simplify the process of fixing the lattice in the stretched position on the ground. 6 Il.

The invention relates to the construction and, in particular, can be used in the construction of the road base service roads, as well as for hardening and protection ocii material - soil and concrete[1], [2], [3], includes many plastic strips that are located on one line and secured together at intervals, and the bands under tension across the width to form a single mesh grille. On the elongated plastic strips, between the seams, while stretching form the walls of the cell, can be performed with a number of holes or not made holes at all. In these technical solutions also use different profile deformation of the plastic strips to bond the pavement in a single unit, ensuring the preservation of the relative position.

During the construction of the road base service grid pre-stretch in the working position, fix their anchors, and then produce the stacking of building material in the cell, then depending on construction material, soil compaction or laying cement concrete.

The disadvantages of the known lattice for containment of the material can be attributed to the fact that the formation of bonds formed between the blocks of the pavement occurs in the holes between cells. Data communication over time under the action of the workload when operating dissolved, and formed not associated block structure, whereas ttkom is what if you extend the grid to localize the material in the working position of the latter is required to lock in the extended position. This requires the grid to stretch with some effort and hold it in this position, fix, i.e. pin to ground. This method of fixation is inconvenient, time-consuming and requires additional effort.

Closest to the proposed invention is a grill for localization of the material [4], which is made of flexible strips set on edge and connected to each other through the gaps seams with the formation of tensile volumetric honeycomb structure in accordance with the invention, the sections of the flexible strips between welds made with at least one concave and/or convex and/or concave-convex section forming a hollow structural element. Moreover, the hollow structural element is made by extruding or pressing and in cross-section forms or rectangular, or tubular, or round, or oval in shape with rounded edges. Described grille for containment of the material not only has a block structure, but at the expense generated between blocks of links increases distributing sposobnosti technical solutions of the prototype can be attributed, what if you extend the grid to localize the material in the working position of the latter is required to lock in the extended position. This requires the grid to stretch with some effort and hold it in this position, fix, i.e. pin to ground. To do this, use special anchors that are driven into the ground. This method of fixation is inconvenient, time-consuming and requires additional effort.

The technical task to be solved by the invention, is to eliminate the disadvantages of the prototype, namely to reduce the complexity and simplify the process of fixing the lattice in the extended (working) position on the ground.

The technical problem is solved by the fact that in the known lattice for containment of material, made of flexible strips set on edge and connected to each other through the gaps of the joints, sections, between which the tensile form the walls of the cell volume of the honeycomb structure according to the invention the edges of the strips facing the ground, made located at the midpoints of the walls of the cells or at the seams connecting the two adjacent bands, triangular, or oval, or trapezoidal, or rectangular protrusions with a height, sostavlyajushie nih bands.

The invention is illustrated by drawings.

In Fig.1 shows the lattice for containment of the material in the stretched view (top view).

In Fig.2 shows a view of the Fig.1 with the lug, located in the middle of the sides of the cells.

In Fig.3 shows a view of the Fig.1 with the lug, located in the middle of the seams, while the lug is made in the form of triangles.

In Fig.4 shows a view of the Fig.1 with the lug, located in the middle of the seams, while the lug is made in the form of oval projections.

In Fig.5 shows a view of the Fig.1 with the lug, located in the middle of the seams, while the lug is made in the form of trapezoidal projections.

In Fig.6 shows a view B of Fig.5, illustrating the location of the weld seam and the side surfaces of the lug.

Grill for localization of material 1 is made of flexible strips 2 mainly made of synthetic materials, for example polyethylene, installed on the edge and interconnected at intervals of 3 joints 4 with the formation of tensile volumetric mesh structure.

To simplify and facilitate the operation for attaching the grille to the localization of the material 1 on the ground flexible strip 2 is provided with lugs 6. The lugs are made for one coal, or oval, or trapezoidal, or rectangular protrusions that are located at the midpoints of the walls of the cells, and the length of the protruding parts is 0.2-1.5 the width of the flexible strip 2.

A special case of manufacturing of a grid provides manufacturing lug in the middle of the weld. In this case, the lugs will be more resistant to bending because it would be double thickness and side walls bent the edges, providing even more stability (Fig.6).

During the construction of the Foundation of the pavement or to strengthen and protect the ground from erosion of slopes, channels, cladding and other similar works grate 1 for the localization of the stretch material in the working position. While the areas between joints 4 flexible strips 2 bend and form the walls of the cell volume of the honeycomb structure. When stretched grid 1 6 lug penetrate into the soil and so on. fixed grid 1 for containment of the material. Then make stacking construction material (cement concrete or treated with cement mineral material) in the cell. When solidification is formed block structure.

Manufacturing lug length is less than 0.2 bandwidth inefficient, because in this case they are no longer in the of cotacao length more than 1.5 bandwidth causes such lugs will be unable to score in the ground. In this case, it is impossible to install the bars in the correct position. It should be noted that the maximum length of the lugs is substantially depends on the material of the ground and the best length can be chosen experimentally. The most viable option when extreme strip equipped with lugs of greater length than the lugs of the inner strips. Longer lugs on the edges of the gratings provide vertical stability of the extreme bands. Since the average band have the balancing tensile load, they may have a shorter lugs.

Thus, the presence of the lug on the flexible strips of the lattice for the localization of material simplifies the process of fixing the latter on the ground, reduces its complexity, does not require hammering into the ground, additional fastening elements, such as anchors.
