Description

A reinforcement belt structure

Technical Field

The present application relates to the field of construction engineering, and in particular to a reinforcement belt structure.

Background Art

With the rapid development of my country's industrial level and economy, large-scale construction projects are increasing. Large buildings often need to use super-long concrete structures. Generally, the concrete of the wall is poured first. However, since the concrete will have a certain shrinkage rate after pouring and may crack, it is traditionally necessary to use post-cast strips to improve the stability of the building structure. However, the post-cast strips can only be poured 60 days after the main structure is poured, which will extend the construction time and affect the construction efficiency.

Therefore, expansion reinforcement strips are now more commonly used to pour shrinkage compensating concrete at the preset post-cast strips of the structure. Expansion reinforcement strips generally include continuous, intermittent and post-cast types according to the pouring method. Since the continuous expansion reinforcement strip can be poured simultaneously with the concrete, it can reduce the construction time and improve the construction efficiency, making it the first choice for offsetting the shrinkage of concrete. However, the current continuous expansion reinforcement strip is a simple structure enclosed by steel bars and wire mesh. When pouring a longer continuous expansion reinforcement strip, the support strength provided by the structure enclosed by the steel bars and wire mesh is insufficient, which has a greater impact on the stability of the entire building.

Utility Model Content

In order to improve the supporting strength of the reinforcement belt, the present application provides a reinforcement belt structure.

The present application provides a reinforcing belt structure, which adopts the following technical solution:

A reinforcing belt structure is arranged between two adjacent walls, comprising two reinforcing belts, two separation nets and a plurality of reinforcing groups, wherein the two reinforcing belts are parallel to each other, and the two separation nets are arranged parallel to each other on the outside of the wall, the reinforcing belt comprises a plurality of longitudinal rods, and the longitudinal rods are arranged in an array along the outside of the wall, and a plurality of reinforcing groups are arranged between the two reinforcing belts at intervals along the length direction of the reinforcing belt, and a group of reinforcing belts comprises a plurality of reinforcing nets connected end to end in sequence, one side of each reinforcing net is connected to a longitudinal rod outside one wall, and the other side of the reinforcing net is connected to a longitudinal rod outside the opposite wall, each reinforcing net forms an angle with the outside of the wall, and two adjacent reinforcing nets form a V-shaped structure on the horizontal projection plane.

By adopting the above technical solution, pouring expansive concrete in the reinforcement belt structure can offset the shrinkage stress caused by shrinkage of the concrete wall, reduce concrete shrinkage cracking, and improve the stability of the building; the reinforcement belt supports the reinforcement belt structure and the walls on both sides and improves the overall strength; the separation net can separate the reinforcement belt structure from the wall, reduce the flow of concrete outside the belt into the reinforcement belt structure, reduce the mixing of expansive concrete and concrete outside the belt, and also provide a certain support effect on the overall structure; the longitudinal rods and the reinforcement net both support the reinforcement belt structure and improve the overall stability of the structure.

Optionally, each of the reinforcement belts includes a first reinforcement frame, the first reinforcement frames of the two reinforcement belts are arranged parallel to each other, and the first reinforcement frame is arranged on the outer side close to the wall, and a plurality of longitudinal rods are arranged on a side of the first reinforcement frame away from the wall.

By adopting the above technical solution, the first reinforcement frame is used to provide a certain support effect for the overall structure of the reinforcement belt, thereby improving the overall strength of the building.

Optionally, each of the reinforcement belts further includes a second reinforcement frame arranged parallel to the first reinforcement frame, two second reinforcement frames are arranged parallel to each other, and the second reinforcement frames are connected to the inner sides of a plurality of longitudinal rods arranged in an array.

By adopting the above technical solution, the second reinforcement frame is used to provide a certain support effect for the overall structure of the reinforcement belt, thereby improving the overall strength of the building.

Optionally, the reinforcement belt further includes a plurality of first cross bars, each of which is arranged close to the ground, and each of which is arranged at the bottom of the reinforcement net.

By adopting the above technical solution, the first cross bar provides a stable supporting force to the bottom of the structure, thereby improving the overall strength of the building.

Optionally, the reinforcement belt further includes a plurality of second cross bars, each of which is disposed on the top of the reinforcement net, and each of which is connected to a pair of longitudinal bars parallel to each other.

By adopting the above technical solution, the second cross bar provides stable support for the top of the structure, thereby improving the overall strength of the building.

Optionally, the second reinforcement frame is a frame body having a plurality of V-shaped structures connected end to end in a longitudinal section.

A second reinforcement frame is formed by connecting multiple V-shaped structures end to end in the longitudinal direction. After concrete is added, the concrete is embedded in the V-shaped structure, which can improve the strength of the reinforcement belt. Combined with multiple reinforcement nets with V-shaped cross-sections, the overall strength of the reinforcement belt can be improved in the transverse and longitudinal directions.

Optionally, the separation net is a steel wire mesh with a mesh diameter of 3mm-8mm.

By adopting the above technical solution, the expansive concrete in the reinforcing belt structure and the ordinary concrete of the wall can be blocked. If the mesh diameter is too small, the amount of steel wire used in the wire mesh will increase, thereby increasing the use cost; if the mesh diameter is too large, the expansive concrete in the reinforcing belt structure and the ordinary concrete of the wall cannot be effectively separated, causing the expansive concrete and the ordinary concrete to mix, affecting the strength of the reinforcing belt structure.

Optionally, the angle between two adjacent reinforcing meshes is 60° to 120°.

By adopting the above technical solution, the supporting strength of the reinforcing mesh to the reinforcing belt can be improved, thereby improving the overall strength of the reinforcing belt; if the angle between adjacent reinforcing meshes is too small, the amount of steel wire used in the reinforcing mesh in the reinforcing belt will increase, thereby increasing the cost of use; although an excessively large angle can reduce the use of steel, it will also reduce the supporting strength of the reinforcing mesh.

In summary, the present application includes at least one of the following beneficial technical effects:

1. By pouring expansive concrete into the reinforcement belt structure, the shrinkage stress caused by shrinkage of the concrete wall can be offset, the shrinkage cracking of the concrete can be reduced, and the stability of the building can be improved; the reinforcement belt supports the reinforcement belt structure and the walls on both sides and improves the overall strength; the separation net can separate the reinforcement belt structure from the wall, reduce the flow of concrete outside the belt into the reinforcement belt structure, reduce the mixing of expansive concrete and concrete outside the belt, and also provide a certain support effect for the overall structure; the longitudinal rods and reinforcement nets both support the reinforcement belt structure, improving the overall stability of the structure

2. The reinforcement belt provides support for the expansion concrete in the reinforcement belt structure and the concrete walls on both sides. At the same time, the separation net separates the reinforcement belt structure that needs to be poured with expansion concrete. Then, by pouring expansion concrete in the reinforcement belt structure, the shrinkage stress caused by shrinkage of the concrete wall is offset, the shrinkage cracking of the concrete is reduced, and the stability of the building is improved;

3. The longitudinal support force is provided by the longitudinal rod, the first reinforcement frame and the second reinforcement frame, the lateral support force is provided by the reinforcement net, the bottom support force is provided by the first cross bar, and the top support force is provided by the second cross bar, thereby improving the overall strength of the reinforcement belt structure and thus improving the overall strength of the building;

4. By limiting the diameter of the reinforcing mesh holes and the angles of two adjacent reinforcing meshes, the use of steel is reduced while ensuring sufficient support effects, thereby improving the economy of the structure.
