Embodiment

[0052] see figure 1 , the reverse order construction method of the formwork engineering of the cast-in-place shear wall structure system includes the following steps:

[0053] (1) Step 1:

[0054] This step includes the (a) process that is carried out simultaneously: erecting the support frame 3, installing the beam slab formwork 1 and (b) process: welding and binding the wall reinforcement 4;

[0055] (a) Process: set up support frame, install beam and slab formwork

[0056] When there is a working surface on the construction floor, the erection work of the supporting frame 3 can be started. After the whole hall support frame 3 is erected, the beam slab formwork 1 is laid. Beam slab formwork 1 adopts the method that beam side formwork 8 wraps beam bottom formwork 9, see image 3 , that is, the beam side formwork 8 clamps the beam bottom formwork 9, and the lower part of the beam bottom formwork 9 is provided with a stiffening square timber 10 to support the beam side for...

Abstract

The invention relates to an inverted construction method for template engineering of a cast-in-place shear wall structure system, which specifically comprises the following operation steps: step one, synchronously carrying out (a) a process of setting up a support frame and mounting a beam plate template and (b) a process of welding and binding wall steel bars; step two, (c) a process of binding beam plate steel bars and (d) a process of mounting a wall template; and step three, (e) a process of integrally casting wall panel concrete. The method is suitable for the industrial and civil engineering adopting a shear wall, in particular a short-pier shear wall structure system, is also suitable for scattered-split support templates or steel frame combined templates, and is further suitable for all steel supports adopted by the beam plate template; the work efficiency is remarkably improved, and the construction period of a main body structure is shortened by about 40 percent compared with the prior construction method; the engineering quality is ensured, namely the root of the wall is ensured to be clean, the dislocation and slag inclusion are prevented, the quality of a joint of the beam plate and the wall is ensured, and the verticality of the wall is ensured; the construction safety is ensured; and the construction period is saved by about 40 percent.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a building construction method of a shear wall structure system. Background technique [0002] At present, cast-in-place reinforced concrete structure systems are widely used in housing construction projects in my country. The main types include frame structures, shear wall structures, short-leg shear wall structures, and frame-shear structures commonly used in various high-rise and super high-rise buildings. Force wall structure, cylinder structure, etc. With the continuous advancement of national energy-saving and land-saving residential buildings, mid-to-high-rise buildings with 10 to 30 floors are more and more widely used by designers, and their structural systems are mostly shear wall and short-leg shear wall structures. One of the characteristics of the cast-in-place reinforced concrete shear wall (short-leg shear wall) structural system is that the construction period...
