Light composite thermal insulation board for fabricated building

Abstract

The invention discloses a light composite thermal insulation board for fabricated building. The light composite thermal insulation board for fabricated building comprises fireproof layers and thermal insulation layers, surfaces of the fireproof layers are in glued connection with surfaces of the thermal insulation layers, a filling groove is formed in an inner cavity of the fireproof layers, and an inner cavity of the filling groove is filled with a fireproof filling material; and the inner cavity of the fireproof layers is fixedly connected with fixing plates, and one sides of the fixing plates are fixedly connected with inserting rods. The invention relates to the technical field of thermal insulation boards. In the light composite thermal insulation board for fabricated building, the fixing plates and the inserting rods are arranged in the thermal insulation layers, the fixing plates and the inserting rods are subjected to one-time machining forming with the thermal insulation layers, the fireproof layers are subjected to machining forming, after the filling groove is formed, the inserting rods are inserted into the fireproof layers, and adhesive glue is applied on the fireproof layers and the thermal insulation layers to be bonded together, inserting bolts are screwed into the inserting rods, such that assembly can be rapidly completed, fireproof and thermal-insulating effects can be achieved at the same time, the use range is wider, and strength of the thermal insulation board is effectively improved.

Description

technical field [0001] The invention relates to the technical field of thermal insulation boards, in particular to a lightweight composite thermal insulation board for assembled buildings. Background technique [0002] The construction industry is an industry that revolves around the design, construction, decoration, and management of buildings. Urban architecture is an important part of a city, and architecture is not just an artificial work for people to stay, rest, and entertain. In terms of aspects, it is related to our economy, culture and life. In the construction industry, a good building needs to use many different boards. For example, by installing lightweight composite insulation boards, the building can get a better insulation effect. [0003] According to the patent No. CN109972752A, there are the following problems in use of a light-weight fireproof composite thermal insulation board with tie bolts and its assembly method: [0004] (1) There is no fireproof lay...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a light-weight composite thermal insulation board for prefabricated buildings, which solves the problem that there is no fireproof layer inside, and when a fire breaks out, the thermal insulation board burns rapidly and increases the fire intensity, which is not safe enough
