Prefabricated non-thermal bridge thermal insulation external wall of rectangular steel pipe keel and manufacturing method thereof

Abstract

The invention relates to a prefabricated non-thermal bridge thermal insulation external wall of a rectangular steel pipe keel and a manufacturing method thereof. The prefabricated non-thermal bridge thermal insulation external wall comprises a base wall body, a break thermal bridge anchoring clamping piece, a thermal insulation board and a stressed-skin diaphragm. The thermal insulation board andthe base wall body are fixedly connected into a whole through the break thermal bridge anchoring clamping piece, and the stressed-skin diaphragm is fixedly arranged on the other side of the base wallbody relative to the thermal insulation board. The prefabricated non-thermal bridge thermal insulation external wall is convenient to construct and simple in structure, and breaks the inherent conceptof 'thermal insulation after wall body' and proposes the concept of integrated production of thermal insulation and wall body; batch production and on-site installation are convenient, the construction efficiency is improved, the characteristics of low energy consumption, flexible arrangement and fast construction are achieved, and the requirement of green construction is met; the use of the break thermal bridge anchoring clamping piece simplifies the construction process, an U-shaped connecting piece is connected with the rectangular steel pipe keel conveniently, and the construction speed is improved; and the setting of the rectangular steel pipe keel improves the integrity of concrete pouring in the later stage, and is beneficial to the overall stress of the structure. Dovetail groovesare arranged to solve the problem of thermal bridges caused by joints and the like, the thermal insulation performance of the wall body is improved and the structural integrity is increased.

Description

Technical field: [0001] The invention relates to the technical field of construction engineering, in particular to a prefabricated thermal bridge-free thermal insulation outer wall with a rectangular steel pipe keel and a manufacturing method thereof. Background technique: [0002] With the rapid development of cities, building energy consumption is increasing year by year, and more and more prefabricated buildings and green construction methods have been put on the agenda. As a key industry for national sustainable development, the building energy-saving industry is an important way to achieve national energy security. The prefabricated passive house is a new type of house with prefabricated concrete components as the enclosure structure, good thermal insulation effect and air tightness, high indoor comfort, and does not use active heating technology. Whether it is from the construction period and construction quality of the house, or from the perspective of the indoor comf...
