Construction technology for pouring concrete of walls on two sides of deformation joint

Abstract

The invention belongs to the field of constructional engineering and particularly relates to a construction technology for pouring concrete of walls on two sides of a deformation joint. The construction technology comprises the following steps of 1 performing steel bar framework construction; 2 installing a wall board thickness control support; 3 performing positioning and paying-off; 4 installing a bottom-layer interior wall template and a scissors type connecting rod keel supporting system; 5 installing a wall outer-side template and a keel supporting system; 6 pouring the concrete; 7 template removal; 8 pouring the concrete of the walls on two sides of the upper-layer deformation joint; 9 repeating the step 8 till all of required floor pouring is finished. The construction technology is simple, convenient and efficient. Materials are saved. The quality accuracy is high. The root portion position control is good.

Description

technical field [0001] The invention relates to a construction process for concrete pouring of walls on both sides of deformation joints, and belongs to the field of construction engineering. Background technique [0002] Due to the small width of the deformation joints on both sides of the concrete structure building deformation joints (generally 10-50CM), it is relatively difficult to only remove the formwork, and it is also very difficult to control the construction quality of the concrete wall. The existing method can only be constructed on one side. After the strength meets the requirements, the other side wall formwork will be supported, and the simultaneous construction on both sides will basically become impossible. Seriously affected the progress of the project. In addition, during the construction process, the support formwork is not easy to support, the construction area is small, and the space for workers to operate is small, so it is difficult to ensure the con...

Problems solved by technology

[0002] Due to the small width of the deformation joints on both sides of the concrete structure building deformation joints (generally 10-50CM), it is relatively difficult to only remove the formwork, and it is also very difficult to control the construction quality of the concrete wall. The existing method can only be constructed on one side. After the strength meets the requirements, the other side wall formwork is supported, and simultaneous construction on both sides is basically impossible

Seriously affected the progress of the project

In addition, during the construction process, the support formwork is not easy to support, the construction area is small, and the space for workers to operate is small, so it is difficult to ensure the construction quality. The formwork support system will expand and run during the concrete pouring process, and the construction quality of the second wall is difficult to guarantee. After the construction is completed, the formwork system of the second wall is not easy to dismantle, and the short wooden braces between the two walls cannot be taken out, which will cause problems. Make the deformation joint useless and endanger the safety of the overall structure
