Problems solved by technology

[0002] With the development of building structure construction technology, a large number of large-depth and high-height shear wall structures have appeared, which has brought many difficulties to the stability and safety of the structural system during construction, especially for the design and construction of the formwork support system. Bringing new research topics, the formwork support system is an important temporary load-bearing and force-transmitting structure in the construction process of concrete structures, which directly affects important issues such as structural construction safety, construction period, and quality; at present, there is no large-height shear wall formwork There is no complete technical solution for support

Embodiment Construction

[0014] Referring to accompanying drawing, a kind of support method of large-height shear wall formwork, its specific technical scheme is as follows:

[0015] The first step: binding the steel bars within 3 meters of the lower part of the shear wall 6, supporting the formwork 7, and pouring concrete;

[0016] Step 2: After the hardness of the concrete at the lower part of the shear wall reaches 75%, remove the formwork, and install the triangular bracket 1 with high-strength bolts 1 meter below the top of the existing shear wall, with a distance of 1 meter;

[0017] The third step: place a 400*50mm scaffolding board 2 on the tripod, and then use a scaffolding steel pipe to build a 1100mm-high protective railing 3 on the plug of each tripod;

[0018] Step 4: Paste double-sided adhesive tape on the top edge of the existing shear wall, then attach the formwork to the existing shear wall, place the lower part of the formwork on the triangular bracket, place vertical wooden squares ...

Abstract

The invention discloses a method of supporting a large-height shear wall form. According to the technical scheme, the method includes firstly, tying rebars on the lower three-meter portion of a shear wall, erecting a form, and pouring concrete; secondly, removing the form; thirdly, placing a scaffold plate 400*50mm on each triangular support, and erecting a 1100mm high guard rail on an inserting head of each triangular support through scaffold steel pipes; fourthly, attaching double-sided adhesive tape to the top of the existing shear wall, tightly attaching the form to the existing shear wall, and placing the lower portion of the form on the triangular supports; fifthly, repeating the steps for both sides, pouring the concrete, maintaining, and removing the form. The method has the advantages that stress performance is good, the rigidity and strength of the form are guaranteed, the form is safe and reliable, over-standard deformation under the constructional load action of poured concrete is avoided, and the geometry of the constructed concrete can be accurate.

Description

technical field [0001] The invention belongs to the field of building construction, in particular to a formwork support system for pouring concrete on site, in particular to a support method for a large-height shear wall formwork. Background technique [0002] With the development of building structure construction technology, a large number of large-depth, high-height shear wall structures have emerged, which has brought many difficulties to the stability and safety of the structural system during construction, especially for the design and construction of the formwork support system. Bringing new research topics, the formwork support system is an important temporary load-bearing and force-transmitting structure in the construction process of concrete structures, which directly affects important issues such as structural construction safety, construction period, and quality; at present, there is no large-height shear wall formwork Support does not have a complete set of tec...
