Mortise and tenon connection assembled self-insulation and heat insulation hollow shear wall system and its hoisting method

Abstract

The invention belongs to the field of building structures, and particularly relates to a mortise and tenon connection and assembly type self-thermal-insulation hollow shear wall system. The mortise and tenon connection and assembly type self-thermal-insulation hollow shear wall system comprises an I-shaped wall plate unit, an L-shaped wall plate unit, a T-shaped wall plate unit, an end wall plate unit and cast-in-place beams; the various wall plate units are gripped with one another and are in mortise and tenon connection to one another in the transverse direction, an epoxy resin concrete binding agent coats mortise and tenon connection portions to form a shear wall body structure, the cast-in-place beams are arranged on tops of the wall plate units, prefabricated connection units are embedded on the upper portions of the cast-in-place beams, and the assembly type self-thermal-insulation hollow shear wall system is formed; and moreover, the various wall plate units are made of glass bead thermal-insulation concrete. By the system, a thermal-insulation technology and a structure system can be combined perfectly, and the thermal-insulation time of a wall is equal to the service life of the structure system; different units are pieced together to form the shear wall and are easy to hoist, and requirements on hoisting equipment are low; and compared with the traditional thermal-insulation shear wall, the system has a hollow structure, the amount of concrete can be reduced, dead weight of the wall is reduced, and construction costs are reduced.

Description

technical field [0001] The invention relates to a hollow shear wall, in particular to a mortise and tenon joint assembled self-insulating hollow shear wall system. Background technique [0002] At present, the most widely used thermal insulation method in my country's construction projects is the method of external wall insulation, but this method has many defects: most of the thermal insulation materials are organic materials such as EPS and XPS, which are expensive and cannot meet the fire protection design requirements ; The insulation layer is prone to water seepage, hollowing, falling off and other common problems; the construction process is complicated, and it is difficult to control the construction quality; the service life of the external insulation layer is generally lower than the design service life of the building, generally about 20-30 years. Therefore, exploring the self-insulation system of building structures has become an ideal model for building energy con...

[0002] At present, the most widely used thermal insulation method in my country's construction projects is the method of external wall insulation, but this method has many defects: most of the thermal insulation materials are organic materials such as EPS and XPS, which are expensive and cannot meet the fire protection design requirements ; The insulation layer is prone to water seepage, hollowing, falling off and other common problems; the construction process is complicated, and it is difficult to control the construction quality; the service life of the external insulation layer is generally lower than the design service life of the building, generally about 20-30 years

This kind of prefabricated shear wall structure has too much wet work on site, the construction process of the insulation layer is complicated, and the wall has a large self-weight

In addition, the prefabricated shear walls of the upper and lower floors are connected by grout anchor or cast-in-place belt, which requires many construction procedures and low shear strength of the walls.
