Installation construction method for large all-steel formwork at internal corner of shear wall

Abstract

The invention discloses an installation construction method for a large all-steel formwork at the internal corner of a shear wall. The installation construction method comprises the following steps of: (1) installing an internal corner steel formwork at the internal corner of the wall, wherein the internal corner steel formwork comprises two vertical steel plates which are welded at a right angle, multiple reinforcing ribs are connected between the two vertical steel plates at intervals, two connecting steel plates are respectively welded at the two sides of each reinforcing rib, and each connecting steel plate is respectively and vertically connected with the vertical steel plate at the corresponding side; (2) respectively connecting and installing a groove type steel plate at the outer side edge of each connecting steel plate along the vertical direction through a lead screw; (3) installing large steel formworks at the two sides of the internal corner of the wall; (4) connecting formwork back ribs on the large steel formworks at intervals; (5) connecting internal corner rolling grooves corresponding to each reinforcing rib with holes arranged on the reinforcing ribs through internal corner hook bolts; and (6) pouring concrete into the shear wall. According to the installation construction method provided by the invention, a formwork system at the internal corner of the shear wall firmly and reliably forms a stable integral system.

Description

technical field [0001] The invention relates to the field of building templates, in particular to a construction method for installation at the inner corners of all-steel large templates for building shear walls. Background technique [0002] Large formwork was first developed and applied in France and other countries in the late 1950s. my country began to develop all-steel large formwork in the early 1970s. The all-steel large formwork currently used in my country is an assembled large formwork; the assembled large formwork can be reassembled to meet the requirements of different board sizes and improve the utilization rate of the formwork. All-steel large formwork is a new type of formwork and scaffolding technology. It is assembled into a building model with 3mm~6mm steel plates. The back and side of the steel plates are connected by matching corrugated strips and connectors to form a solid formwork structure. Compared with the traditional wooden formwork, the all-steel ...

Problems solved by technology

[0011] Although the 3rd to 5th patents have a series of advantages, they cannot solve the problem of mass production and supply to the construction site

[0015] Although the 7th and 8th patents have a series of advantages, they cannot guarantee the rigidity and deformation of the template at the inner corner when the lateral pressure is too large when pouring concrete.

Although this patent has a series of advantages, it cannot guarantee the rigidity and firmness of the template at the inner corner
