Description

Shear wall structure deformation joint template

technical field

The utility model relates to a construction template for a main body of a building structure, in particular to a deformation joint template for a shear wall structure.

Background technique

As high-rise residential buildings become an important part of urban construction, the design of deformation joints is inevitable. During the installation of formwork for construction deformation joints, especially when the distance between deformation joints is narrow, the following construction techniques are often used:

1. After the reinforcement of the shear walls on both sides of the deformation joint is bound, a polystyrene foam board with the same width as the deformation joint is inserted in the middle of the deformation joint. , the overall verticality is not easy to control, so that the verticality of the wall cannot be guaranteed, the cost is high, and the vertical perception after the concrete is formed is poor.

2. A wooden box with the same width as the deformation joint is used in the middle of the deformation joint. When pouring concrete, the shear wall concrete on both sides is poured at the same time. The wooden box cannot be removed and becomes a rigid filling material, which affects the function of the deformation joint and wastes materials.

The traditional construction technology is relatively complicated, and it is generally impossible to guarantee the component size, flatness, verticality, thickness of the protective layer of the shear wall reinforcement, concrete density and visual quality of the shear wall. At the same time, the exposed corrosion of the reinforcement in some deformation joints cannot be avoided. affect the safety performance of the structure.

Between the strip-shaped flat irons on the left and right sides are arranged a number of vertical support bars that are close to them and distributed front and back. The tops of the vertical support bars are There are fixed lifting rings, all the fixing rings are pierced with a through square wood, and there are a number of pull screws with both ends extending out of the shear wall between the shaped templates; The L-shaped bolts corresponding to the iron position, the short sides of each pair of L-shaped bolts are inserted into the corresponding strip flat iron and the shaped template, and the long sides of each pair of L-shaped bolts are screwed with tensioning screws located outside the head template. nuts.

In the deformation joint of the shear wall structure, the vertical supporting steel bar cooperates with the fixed suspension ring on the top and the through square wood to make the rigid support of the vertical supporting steel bar unified as a whole. The overall performance of the positioning formwork; when removing the formwork, after removing the pull screw and the L-shaped bolt, remove the strip-shaped square wood on the top of the vertical support reinforcement, and then pass the steel pipe through the fixed ring and rotate it to loosen it. Use a tower crane to remove and remove the vertical supporting steel bars and shaped formwork. Before removing the shaped formwork, pull out the reinforcing screw and remove the corresponding PVC casing. Pull out the horizontal supporting steel bars and remove the supporting sleeve before hoisting. The head formwork is removed, and finally the other wall formworks are removed, which overcomes the problem that the deformation joints of the existing shear wall structure cannot guarantee the flatness and verticality of the concrete and affect the safety performance of the structure.

The stereotyped formwork is composed of two layers of formwork distributed on the left and right, each layer of formwork is composed of several formwork bodies distributed front and back, and the joints of the two layers of formwork bodies are arranged alternately.

The vertical supporting steel bar is composed of two fixed steel bar bodies distributed left and right.

The structure design of the utility model is reasonable and reliable, and realizes the requirement that the shear wall formwork on both sides of the deformation joint is supported at the same time, thereby ensuring the component size, flatness, verticality, thickness of the protective layer of the shear wall reinforcement and concrete The compactness effectively improves the safety and quality problems in the construction process, and the operation is convenient and fast, which effectively improves the construction efficiency. It has the advantages of simple structure, convenient processing and low cost.
