Description

A vertical hoisting structure of an assembled fully prefabricated steel wire grid sandwich wall panel

technical field

The utility model relates to the field of structural engineering, in particular to a vertical hoisting structure of an assembled fully prefabricated steel wire grid sandwich wall panel.

Background technique

The steel wire grid sandwich wall panel has the characteristics of light weight, high strength, good thermal insulation performance, good sound insulation performance, and fire performance that meets the requirements of the code; at the same time, the space steel grid frame is installed inside the wall panel, and the bearing capacity can be designed. , The steel wire mesh on the surface layer can prevent the cracking of the board surface and other advantages. Its traditional production and molding method is to first fix the steel wire mesh frame sandwich layer on the main structure of the building with equidistant tie bars, and then spray the concrete (or cement) on both sides on the site to form it. It belongs to semi-prefabricated and semi-cast-in-place product.

In recent years, driven by the policies of "Green Building Action" and "Building Industrialization, Housing Industrialization" and economic development, prefabricated green buildings and green energy-saving building wall materials have become domestic research and exploration hotspots. Therefore, it is of great significance to improve and fully prefabricate the traditional lightweight steel wire grid sandwich wall panels to realize the industrialized production and assembly construction of fully prefabricated steel wire grid sandwich wall panels.

And a key technical problem in the production and construction of prefabricated fully prefabricated steel wire grid sandwich wall panels is the hoisting of the wall panels. It is different from the hoisting of the traditional lightweight steel wire grid sandwich wall panels, because the traditional steel wire grid sandwich wall panels only hoist the very light weight steel wire grid sandwich layer, while the assembled fully prefabricated steel wire grid According to the characteristic requirements of the prefabricated building, the core wall panel is often the whole wall panel (the height of the wall panel is the height of the building floor, and the width of the wall panel is the width of the building bay), and its own weight can be as high as more than 4 tons; high. It is also different from the hoisting of the existing prefabricated fully prefabricated concrete wall panels, because the thickness of the concrete layer of the existing prefabricated fully prefabricated concrete wall panels is relatively thick, not less than 80mm, even as high as 170mm, and the lifting device can be directly In the pre-buried and concrete surface layer, the bearing capacity of the embedded parts of the spreader is reliably guaranteed; while the concrete surface layer on both sides of the prefabricated fully prefabricated steel wire grid sandwich wall panel is very thin, usually 50mm. It is difficult to guarantee the bearing capacity if it is embedded in the surface concrete; if in order to meet the load-bearing and structural requirements of the embedded parts, the wall panel is designed with solid concrete at the position of the embedded part, which will affect the thermal insulation and energy-saving performance of the wall panel.

Utility model content

The technical problem to be solved by the utility model is to provide a vertical hoisting structure of an assembled fully prefabricated steel wire grid sandwich wall panel. The vertical hoisting structure has a simple structure and excellent mechanical properties. The impact of the buried spreader on the function of the wall panel is minimized, and the cost of the wall panel is reduced.

The technical scheme adopted by the utility model to solve the above problems is: a vertical hoisting structure of an assembled fully prefabricated steel wire grid sandwich wall panel, including a steel wire grid arranged in the wall panel, and the steel wire grid includes steel wire Mesh, the steel wire mesh is welded by horizontal steel wire and longitudinal steel wire, the wall panel is equipped with a hanger, the two ends of the hanger are set in the wall panel and welded with the longitudinal steel wire, and at the position of the hanging point in the wall panel The steel wire mesh frame in the wall panel is strengthened by a diamond-shaped strengthening mechanism, and the diamond-shaped strengthening mechanism and the steel wire mesh frame are connected by welding. The utility model is suitable for an in-plane vertical hoisting structure of an assembled fully prefabricated steel wire grid sandwich wall panel. Make full use of the load-bearing characteristics of the vertical hoisting wall panels in the plane, directly connect the hoisting device to the longitudinal steel wires of the steel wire mesh sheets on both sides of the wall panel, so that the hoisting load is directly transmitted to the longitudinal steel wires of the steel mesh sheets through the hoisting device, and use the steel wire mesh The longitudinal steel wire of the sheet is axially tensioned to carry the hoisting load, the material properties are fully utilized, and the mechanical properties are excellent. The spreader is directly connected with the steel wire grid of the wall panel, and the steel wire grid is directly stressed, which avoids the complicated and strict structural requirements of the concrete embedded parts, and makes the structure of the embedded spreader the most simplified, and the function of the embedded spreader to the wall panel impact is minimized.

The wall panel is composed of a concrete surface layer, a sandwich layer and a steel wire mesh frame, the sandwich layer is arranged between the concrete surface layers, and the steel wire mesh frame simultaneously connects the sandwich layer and the concrete surface layer to form an integral structure. The steel wire mesh frame is composed of a steel mesh sheet located in the concrete surface layer, and oblique insertion wires welded to the steel wire mesh sheet and passing through the sandwich layer, and the oblique insertion wires are staggered in one direction. The steel wire mesh is in the shape of a square grid; the transverse steel wires are arranged along the width direction of the wallboard, and the longitudinal steel wires are arranged along the height direction of the wallboard. The spreader spans the concrete surface layer and the sandwich layer, and is set in the concrete surface layer after being connected with the steel wire mesh sheets on both sides of the wall panel. The rhombus strengthening mechanism is a rhombus structure formed by connecting four reinforcing steel wires. Since the oblique insertion wires of the steel wire mesh frame in the fully prefabricated steel wire mesh frame sandwich wall panel are arranged in a one-way staggered manner, it is reflected in the individual force transmission mode of multiple groups of plane trusses, and the joint work performance of the longitudinal steel wires of the steel mesh sheet is poor, and the At the lifting point, a single longitudinal steel wire often does not meet the requirements for lifting capacity. Therefore, the reinforced steel wire combined into a diamond-shaped plane is used to strengthen the steel wire grid, and the diamond-shaped hoop effect is used to increase the cooperative work performance of adjacent longitudinal steel wires at the hoisting point in the steel wire mesh, so that the bearing capacity of the embedded parts is reliably guaranteed. . In addition, the spreader is directly connected to the wire mesh frame, making full use of the space force performance of the wire mesh frame; the diamond-shaped plane reinforced steel wire improves the steel wire mesh of the square mesh into a triangular mesh, and the overall stability is more excellent.

In summary, the beneficial effects of the utility model are:

1. The utility model has excellent mechanical properties, which greatly improves the overall stability and cooperative work performance of the steel wire mesh frame of the wall panel at the hanging point, so that the pre-embedded bearing capacity of the spreader is reliably guaranteed;

2. The utility model avoids the complex and strict structural requirements of the concrete embedded parts, the structure of the embedded spreader is the most simplified, the impact of the embedded spreader on the function of the wall panel is minimized, and the cost of the wall panel is reduced.
