Description

Technical Field

[0001] The invention relates to the technical field of civil engineering equipment, in particular to a method for constructing a settlement joint double-wall formwork reinforced structure. Background Art

[0002] In multi-story or high-rise civil buildings, since the units of the buildings are numerous and the length is long, settlement joints need to be set at stress concentration or intermediate unit locations to prevent the various parts of the buildings from cracking due to uneven settlement of the foundation. However, the width of the settlement joints of buildings is generally 200mm, which leads to the problem of no operating space in the shear wall formwork construction on both sides of the expansion joint, making the installation and removal of the formwork very difficult.

[0003] In the prior art, in order to facilitate the demolding of the expansion joints during construction, soft foam materials such as extruded boards are placed between the double-wall formworks at the expansion joints, and then the double-wall formworks are connected to the steel pipe keel by tension bolts, thereby completing the reinforcement of the formworks of the two walls. However, after the polystyrene boards are set in the double walls, the polystyrene boards are poured into the settlement joints and cannot be removed, which not only has a high cost but is also unfavorable for the settlement of the structures on both sides of the settlement joints, and the settlement friction of the building generates noise during later use. Summary of the invention

[0004] The object of the present invention is to provide a method for constructing a double-wall formwork reinforcement structure of a settlement joint to solve the problems raised in the above-mentioned background technology.

[0028] When in use, first prepare the wooden formwork according to the length and height of the wall, then assemble it into a whole to form the formwork 1, and then vertically arrange the secondary purlins 102 on the surface of the formwork 1, with a spacing of 150mm between the formwork 1 and the secondary purlins 102, and fix them with nails.

[0029] The main keel 103 is placed on the side of the secondary keel 102 away from the template 1. The main keel 103 and the secondary keel 102 are placed vertically. The main keel 103 is set from the bottom. The first main keel 103 is 200mm from the ground, and then one is set at an interval of 450mm. The distance between the top three can be 500mm. First, three steel bars 104 with a diameter of 14 are vertically set to weld the main keel 103 into one, and the main keel 103 is connected to the template 1. A U-shaped block 501 is set on the side of the main keel 103 close to the template 1. The U-shaped block 501 and the secondary keel The main keel 103 is aligned with the secondary keel 102, pushing the main keel 103 to slide on the surface of the secondary keel 102.

The sleeve 1 201 and the tension bolt 203 can not only protect the tension bolt 203 to prevent it from being cast in the wall and unable to be removed, but also form a supporting effect for the templates 1 on both sides during reinforcement, to prevent the template 1 from being reinforced too much, resulting in an uneven surface of the cast wall. The corresponding template 1 on the other side is installed, and the end of the tension bolt 203 extends out of the screw hole 105 of the template 1, and the butterfly clip 204 is inserted into the surface of the tension bolt 203. The nut 205 is rotated to fix the butterfly clip 204 on the surface of the main keel 103. The other tension bolts 203 are made in the same way. After tightening one by one, the wall is reinforced and the next pouring process can be carried out.
