Bridge-cut-off composite self-thermal insulation block

Abstract

The invention discloses a bridge-cut-off composite self-thermal insulation block, belongs to the field of architectural technology, and especially belongs to the field of brick and block structure of building walls. Characteristics of the bridge-cut-off composite self-thermal insulation block are that, a plurality of through holes are arranged in a block body along the height direction; a polyurethane foam hole is arranged in the middle part of the block body, wherein the polyurethane foam hole and the through holes are parallel, the depth of the polyurethane foam hole and the height of the block body are identical, the length of the polyurethane foam hole is less than the length of the block body, and distances are designed between the ends of the polyurethane foam hole in the length direction and corresponding ends of the block body in the length direction respectively; and a rigid polyurethane foam layer is arranged in the polyurethane foam hole. The bridge-cut-off composite self-thermal insulation block possesses excellent cohesiveness and heat retaining property, is convenient for production and construction, and is capable of increasing the integral strength of exterior wall systems, and eliminating security risks.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to the technical field of brick and block structures used for building walls. Background technique [0002] At present, the domestic building insulation layer is mainly based on the external thermal insulation construction method, supplemented by the internal thermal insulation construction method, and both construction methods have shortcomings. The external insulation method is more economical, but the fire performance is poor, the wind resistance and weather resistance are insufficient, the effective service life of the building insulation layer is relatively short, especially the heat capacity material is extremely poor (polystyrene foam board and polystyrene extruded foam board), although the performance of thermosetting materials is relatively good, but they cannot withstand the temptation of economic interests, cut corners, and the construction is not standardized, so the p...
