Thermal-bridge-free reinforced connecting body for prefabricated concrete wall column and main wallboard

Abstract

The invention provides a thermal-bridge-free reinforced connecting body for a prefabricated concrete wall column and a main wallboard, and belongs to the technical field of prefabricated concrete buildings. The thermal-bridge-free reinforced connecting body comprises the main wallboard, the wall column and connecting stirrup pieces, wherein wall column convex ribs are arranged on one sides of theupper end and the lower end of a wall column base body in the wall column, and a wall column connecting groove is formed between the wall column convex ribs; and an in-column short insulation board isarranged in middle portion of the wall column base body, and in-column long insulation boards are arranged on the upper side and the lower side of the in-column short insulation board. The thermal-bridge-free reinforced connecting body for the prefabricated concrete wall column and the main wallboard has the beneficial effects that the overall connection cooperation performance is good, the installation operation is remarkably simplified, the industrialization degree is higher, the connection strength and stability are improved, connection joints are effectively prevented from sliding or deforming easily, a thermal bridge at a joint connecting position can be effectively cut off, the material loss rate is extremely low, and construction waste is not generated.

Description

technical field [0001] The invention belongs to the technical field of prefabricated concrete buildings, and in particular relates to a reinforced connection body without a thermal bridge between a prefabricated concrete wall column and a main wall board. Background technique [0002] Building energy conservation is a policy strongly advocated by the national government. One of the main measures is thermal insulation to control the transfer of indoor and outdoor heat so as to achieve the effect of building energy conservation. The overall material of the roof, wall and floor. After the 1970s, foreign countries generally paid attention to the development of thermal insulation materials and their application in buildings. New thermal insulation materials are also emerging continuously, striving to greatly reduce energy consumption, thereby Reduce environmental pollution and greenhouse effect. However, in our country, before 1980, the development of thermal insulation material...

AI Technical Summary

Problems solved by technology

In terms of building energy consumption, the energy consumption caused by exterior walls accounts for more than 50% of the total building energy consumption. Therefore, wall insulation is the key to realizing building energy conservation. The environmental hazards of clay brick production are well known. It consumes a lot of energy, and the exhaust gas produced causes air pollution, greenhouse effect and acid rain. The existing buildings have the problem that the insulation effect cannot be kept in good condition for a long time. The reason is that the insulation cotton in the wall will absorb the air into the wall After a long time, the insulation cotton in the wall will decrease due to the increase of damp quality, the insulation capacity will be weakened, and the living comfort will also decrease.
