Cast-in-situ heat preservation and heat isolation beam, column or shear wall and construction method thereof

Abstract

The invention discloses a cast-in-situ heat preservation and heat isolation beam, column or shear wall and a construction method thereof. The cast-in-situ heat preservation and heat isolation beam, column or shear wall comprises outer side concrete, a heat preservation and heat isolation plate and inner side concrete, wherein cavities are formed in the heat preservation and heat isolation plate; and reinforcement ribs are arranged in the cavities. The construction method comprises the following steps of: binding a steel bar cage, arranging the heat preservation and heat isolation plate and a steel bar net, arranging the reinforcement ribs, fixing the heat preservation and heat isolation plate, and erecting an inner side template and an outer side template; and pouring the inner side concrete and the outer side concrete, after the concrete reaches certain strength, dismantling the inner side template and the outer side template to form the cast-in-situ heat preservation and heat isolation beam, column or shear wall. Due to the cavities, pressure difference of the concrete on two sides of the heat preservation and heat isolation plate during in-situ casting of the concrete is reduced; the reinforcement ribs arranged in the cavities and the concrete in the cavities form reinforced concrete short columns; the connection force of the inner layer concrete and the outer layer concrete is increased, and vertical relative displacement of the inner layer concrete and the outer layer concrete is reduced; and finally, the automatic heat preservation and heat isolation beam, column or shear wall which is easy to construct, low in manufacturing cost, high in durability and high in heat preservation and heat isolation performance is obtained.

Description

Technical field: [0001] The invention relates to the technical field of construction, in particular to a cast-in-place thermal insulation beam, column, shear wall for construction and a construction method thereof. Background technique: [0002] With the development of energy-saving buildings, the requirements for thermal insulation of houses are getting higher and higher. But at present, most of the thermal insulation of beams, columns and shear walls adopts thermal insulation mortar and external thermal insulation boards. These thermal insulation methods have disadvantages such as difficult construction, high cost, poor durability and thermal insulation. Invention content: [0003] The purpose of the present invention is to provide a self-insulating beam, column and shear wall with simple construction, low cost, good durability and thermal insulation. [0004] The present invention is realized by using cast-in-place thermal insulation beams, columns and shear walls for ...
