Decorative heat insulation structure of external wall of building and construction method of decorative heat insulation structure

Abstract

The invention relates to the field of energy conservation and heat insulation of buildings, in particular to a decorative heat insulation structure of an external wall of a building and a construction method of the decorative heat insulation structure. The decorative heat insulation structure comprises fasteners fixedly connected to a wall surface to be subjected to decorative heat insulation, wherein the fasteners comprise substrates which are parallel to the wall surface and are arranged in a spacing manner; edge closing slots extending towards two sides are formed in the substrates, and notches of the edge closing slots are parallel to the wall surface; the edge closing slots are connected with edges of decorative boards on two sides in a clamping manner; inner slots convexly extending towards a direction away from the wall surface are formed in the surfaces of the substrates; the bottoms of the inner slots are parallel to the wall surface; embossed connection blocks are arranged at the inner slots in every two adjacent upper and lower substrates; a space among the substrates, the decorative boards and the wall surface is filled with a heat insulation material; an embossed connection block is arranged between every two adjacent fasteners, so that the mounting intensity and the flatness are guaranteed; and by filling of the heat insulation material, gaps among the decorative boards, the substrates and the wall surface during mounting are effectively eliminated, so that the heat insulation performance of the external wall is improved. The construction method provided by the invention is easy and convenient to operate and high in mounting efficiency.

Description

Technical field [0001] The invention relates to the field of building energy-saving and thermal insulation, in particular to a decorative thermal insulation structure of a building exterior wall and a construction method thereof. Background technique [0002] Energy is an important material foundation for the development of the national economy and the improvement of people's lives, and energy use in buildings is related to the national economy and people's livelihood. The national "13th Five-Year" plan clearly states that the promotion of building energy efficiency and green building development is an objective requirement for implementing the national energy production and consumption revolution strategy, and is to accelerate the construction of ecological civilization and take the road of new urbanization. An important manifestation is an effective means to promote energy conservation, emission reduction and response to climate change, as well as an innovation-driven and new d...

Problems solved by technology

[0003] The applicant has proposed a decorative and thermal insulation structure that facilitates on-site installation of decorative panels and simultaneously enhances the thermal insulation performance of the external wall in the patent titled "A Decorative Thermal Insulation Structure for External Walls of Buildings". On the wall, the fastener includes a base plate that is parallel to the wall and arranged at intervals. The base plate is provided with an edge receiving groove parallel to the wall face downward, and the edge receiving groove snaps onto the upper edge of the decorative board. The insulation layer is filled between the base plate, the lower decorative board and the wall, and the decorative board bracket is pre-built, and then the decorative board is fixed and the thermal insulation material is poured between the decorative board and the wall, so as to avoid the thermal insulation material and the wall. There is a gap between the surfaces to ensure the insulation effect, but there is a lack of connection between the adjacent bracket fasteners, the installation strength is not enough and the decorative panels on the adjacent fasteners need to be leveled again
