Building envelope inner and outer wall anti-seismic and sound insulation anti-cracking integrated structure and construction method thereof

Abstract

Disclosed are a building envelope inner and outer wall anti-seismic and sound insulation anti-cracking integrated structure and a construction method of the structure. An outer wall is connected with the outer side of a frame column to form an integrated building envelope surrounding the frame column, one part of the frame column is embedded in the outer wall, the outer wall is a cast-in-place sandwich wall, the outer wall is filled with light porous inorganic core materials, a lightgage steel joist in the core materials is anchored with face plates on the two sides, the outer wall is connected with the inner wall through connecting ribs, and a reinforcing keel is arranged on the connecting portion. According to the structure, containment and heat preservation are integrated, connection between the cast-in-place light inorganic heat preservation composite outer wall and the constructed inner wall is successfully achieved, the good heat preservation, sound isolation and deformation anti-cracking treatment is achieved, industrial wastes are recycled to be used as raw materials to form nonflammable inorganic foam heat preservation slurry, and due to the rich porous structure in the slurry, the slurry has the excellent heat preservation and sound isolation effects. According to the structure and the method, form removal is not required, construction is easy, the forming speed is high, maintenance is not needed, flexible and continuous casting can be achieved, the building construction efficiency is improved by 30 percent, and the cost is reduced by more than 10 percent.

Description

technical field [0001] The invention relates to the technical field of green and energy-saving construction of buildings, in particular to an integrated anti-seismic, sound-insulating and anti-cracking structure of inner and outer walls of an enclosure structure and a construction method thereof. Background technique [0002] This invention is a subject of the national 12th Five-Year Science and Technology Support Plan, and it is a research and demonstration of key technologies for green energy saving in public institutions. It aims to develop green buildings, promote energy conservation and emission reduction, and provide a set of green energy-saving technologies that are technically applicable and economically reasonable. system, strengthen energy resource management, and realize green construction and low-carbon economy. [0003] In the traditional construction technology, the infill wall is built between the frame columns to form a continuous enclosure wall, and then the...

Problems solved by technology

[0004] The purpose of the present invention is to provide an integrated structure of anti-seismic, sound insulation and anti-cracking of the inner and outer walls of the enclosure structure and its construction method, so as to solve the problem that in the traditional technology, the outer wall is only set between the frame columns, there are broken bridges, and the external insulation design of the wall is required. , complex structure, large amount of building materials, complex construction process, low construction efficiency, unsatisfactory sound insulation and heat insulation effect of the wall, and the secondary plastered wall is generally easy to fall off; at the same time, it also solves the problem that the existing pouring wall is multi-purpose For interior walls or partition walls, when used for frame exterior wall structures, there are broken bridges at the frame column, resulting in poor heat insulation effect of the wall; However, the cost of traditional thermal insulation materials is high, and some components are likely to cause environmental pollution and endanger human health; it also solves the problem that the connection operation between the inner and outer walls is complicated or not connected in the prior art, resulting in unreliable connection and poor connection. There are cracks, poor insulation and sound insulation
