Embodiment Construction

[0055] Now combined with the manual Figure 1-13 The present invention is described in further detail:

[0056] 1. Template processing and production:

[0057] 1) Configure formwork according to the size of the wall at the settlement joint, use 15mm thick multi-layer board 3, and use 40*90 wood square 1 as the back corrugation.

[0058] 2), fix the steel pipe 8 on the back of the wooden square 1 with the customized bolt 11, so that the steel pipe and the formwork are integrated, see for details image 3 :

[0059] 3) Fix the steel pipe 8 and the formwork 10 through custom-made bolts 11: open holes at intervals on the wooden square back corrugated with a hole diameter of 16 mm. Custom Bolt Press figure 2 Arrangement, the steel pipe and the formwork are fixed as a whole, and the total thickness of the customized formwork is 130mm.

[0060] 4) According to the elevation size and avoiding the position of the column wall reinforcement, pop up the hole position of the wall scr...

Abstract

The invention discloses a construction method for mounting a deformation joint template at double walls, comprising the following steps of: 1) fabricating a formed template on a plane; 2) fixing a deformation joint template; 3) placing and fixing cement support blocks according to the corresponding positions and the number of screws; and 4) lifting the template in place by a tower crane and lifting the template to the inner side of a deformation joint and placing the template on supporting reinforcing steel bars. According to the method provided by the invention, the operation is simple and the control is easy; the concrete formation quality is stable, so that stepwise construction on the two sides of the deformation joint can be conducted conveniently without influencing the construction of the next step; the temperate is transferred for a plurality of times and is not easy to deform; and fillers such as a polystyrene board does not need to be filled in the deformation joint, so that the economical benefit is improved and the potential safety hazards of the construction site are reduced.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a construction method for installing a formwork for deformation joints at double walls. Background technique [0002] In order to prevent the impact on the use and safety of the building due to factors such as temperature changes, uneven settlement, and earthquakes, the building is disconnected at the deformation-sensitive parts in advance during design, and divided into several relatively independent units, and the reserved gaps can To ensure that the building has enough deformation space, the structural joints set are deformation joints. However, in the construction of shear walls in high-rise buildings, due to the small space at the deformation joints, it is difficult to set up and remove the formwork, which brings certain difficulties to the engineering construction. [0003] In view of the above problems, the present invention provides a construction method ...
