Abstract

The invention discloses a composite heat-insulation truss, a wall comprising the composite heat-insulation truss and a construction method of the wall. The composite heat-insulation truss comprises astrip-shaped heat-insulation material and a truss framework arranged outside the heat-insulation material in a sleeving manner; the section of the truss framework is rectangular; the truss framework comprises upper-string reinforcing steel bars, lower-string reinforcing steel bars and web member ribs arranged among the upper-string reinforcing steel bars and the lower-string reinforcing steel bars; and the heat-insulation material and the truss framework are bonded. The composite heat-insulation wall is reasonable in structural arrangement, excellent in fireproof performance, good in durability and simple in construction procedure. More importantly, the composite heat-insulation truss can be combined with the wall flexibly. By the aid of the composite heat-insulation truss, the wall comprising the composite heat-insulation truss and the construction method of the wall, the problems about laying of block heat-insulation materials of large prefabricated composite heat-insulation walls incold regions are solved efficiently, heat-insulation layers and structure layers are connected closely, and meanwhile, the problems of cold bridges of embedded columns, hidden beams and hanging installation nodes are well solved.

Description

technical field [0001] The invention relates to the technical field of thermal insulation walls, in particular to composite thermal insulation trusses, walls containing composite thermal insulation trusses and construction methods thereof. Background technique [0002] The prefabricated composite thermal insulation wall has the characteristics of good fire resistance, good durability, and simplified construction procedures, and has a good application prospect in the field of building industrialized exterior walls. [0003] At present, there are two ways to make the insulation layer of the composite thermal insulation exterior wall: one is to lay block insulation materials such as rock wool, extruded board, and vacuum insulation board; the other is to lay pourable insulation materials such as microporous concrete. [0004] The connection of each functional layer in the composite wall is the key of the composite thermal insulation wall. There are two types of connectors commo...
