Embodiment

[0041] A construction method for a double shear wall formwork at a deformation joint of a high-rise building, comprising the following steps:

[0042] step 1

[0043] First construct the shear wall on one side of the deformation joint, bind the steel skeleton for 1', carry out anti-leakage treatment on the sticky sponge strip at the bottom of the formwork, and set up multiple horizontally at the position of the shear wall to be poured at the bottom of the deformation joint to support the outer formwork the supporting steel bar 2', use the tower crane 6' to vertically place the outer formwork 3' on the supporting steel bar;

[0044] Step 2

[0045] After the outer formwork 3' is temporarily in place, the inner formwork 8' is hoisted to the working floor by a tower crane, so that the inner formwork 8' and the outer formwork 3' are relatively parallel to each other, and the steel skeleton 1' is located inside and outside. Between the formwork; then fix the outer formwork 3' and...

Abstract

The invention relates to a construction method of double shear wall formworks at a deformation joint of a high-rise building, in particular to a construction method of double shear wall formworks at a deformation joint of a high-rise building. The construction method comprises the following steps: firstly constructing a shear wall at one side of the deformation joint; binding reinforcing steel bars; carrying out slurry leakage-proof treatment on a lower opening of the formwork; arranging an outside steel formwork of a wall body and an inside wooden formwork of the wall body; installing a wall penetrating screw, tightening the wall penetrating screw and rectifying the verticality of the wall penetrating screw; pouring concrete; removing the formworks; and finally constructing the shear wall at the other side of the deformation joint. With the adoption of the construction method provided by the invention, the phenomena of formwork shifting and slurry leaking cannot easily occur, the quality of pouring the concrete can be effectively controlled, the construction cost is effectively saved, and the problem that cracks and damage can be caused to a building in swinging is solved. With the adoption of the construction method provided by the invention, after the construction of the shear wall at one side of the deformation joint is completed, the outside steel formwork can be immediately hung to the shear wall to be constructed at the other side of the deformation joint by a tower crane, and the steel formworks are used in an alternating and circulating manner to form a line production operation, so that the working time is effectively shortened.

Description

technical field [0001] The invention relates to a construction method for high-rise buildings, in particular to a construction method for double-shear wall formwork at deformation joints of high-rise buildings. Background technique [0002] In order to prevent and avoid the occurrence of building cracks and damage, the building components are generally vertically disconnected in these sensitive parts, leaving a certain gap, and the building is divided into several independent parts to form rigid units that can deform freely without affecting each other. The reserved gaps that separate the disposal of the building are called deformation joints. In high-rise structures, the width of the deformation joint is generally 20-35cm, and the two sides of the deformation joint are shear walls. [0003] In recent years, with the rising housing prices, high-rise shear wall structure housing has developed rapidly. With the continuous expansion of the scale of the building, the shape of ...
