Notched heat-insulating beam

Abstract

The invention discloses a notched heat-insulating beam, which comprises a reinforced concrete notched beam (1) and a heat-insulating sandwich layer (2) for heat insulation, wherein both ends of the reinforced concrete notched beam are rectangular cross sections, the middle section is a concave cross section, the sizes of the cross sections and reinforcement amount are determined by calculating through design, and the notched size, namely the size of the heat-insulating sandwich layer is determined by calculating through the design. The notched heat-insulating beam can enhance the heat-insulating performance of a structure, improve the ductility of the structure and accelerate construction speed, and is a heat-insulating combined beam which has low engineering cost and is convenient to construct.

Description

technical field [0001] The invention relates to a slotted thermal insulation beam. Background technique [0002] At present, the research on walls at home and abroad has made great progress. The common wall insulation systems include external wall thermal insulation systems, external wall internal thermal insulation systems and composite thermal insulation wall systems. However, insufficient attention has been paid to the thermal insulation of the beams. The existence of cold and thermal bridges in the beams of the building facades has greatly reduced the thermal insulation of the building facades. In order to achieve the thermal insulation effect, people still have to install thermal insulation materials on the outer beams of the house, which not only wastes a lot of building materials, but also brings a series of problems such as durability and unstable thermal insulation effect. Contents of the invention [0003] The purpose of the present invention is to improve the c...

Problems solved by technology

However, insufficient attention has been paid to the thermal insulation of the beams. The existence of cold and thermal bridges in the external facade beams has greatly reduced the thermal insulation of the external facade of the building.

In order to achieve the thermal insulation effect, people still have to install thermal insulation materials on the outer beams of the house, which not only wastes a lot of building materials, but also brings a series of problems such as durability and unstable thermal insulation effect.
