A prefabricated composite thermal insulation exterior wall and its construction method

Abstract

The invention relates to the technical field of architecture, in particular to a prefabricated composite thermal insulation external wall and a construction method thereof. Comprises an outer side plate, an inner side plate and a new connecting piece, wherein the outer side plate and the inner side plate are fixedly connected through the new connecting piece to form an insulating layer. This paperadopts prefabricated assembly in the factory, only need to install in the site, its wall quality is reliable, easy to industrialize, the site wet operation less, shorten the construction period. Theinvention aims at providing a lightweight, environment-friendly, fire-resistant, sound-insulating, heat-insulating and durable prefabricated composite heat-insulating outer wall.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a prefabricated composite thermal insulation exterior wall and a construction method. Background technique [0002] So far, more than 30 provinces and cities across the country have issued special guidance and related supporting measures for prefabricated buildings, and many places have put forward clear requirements for prefabricated buildings. In the wave of construction industrialization promotion, its prefabricated composite exterior wall will be vigorously promoted and applied. [0003] At present, the wall materials used for the outer enclosure of steel structure buildings mainly include autoclaved aerated concrete blocks, concrete hollow blocks, and lightweight slats and other wall materials. In order to achieve functions such as building insulation and decoration, it is necessary to plaster, lay external wall insulation materials, and paste facing bricks on the wall fo...

AI Technical Summary

Problems solved by technology

In order to achieve functions such as building insulation and decoration, it is necessary to plaster, lay external wall insulation materials, and paste facing bricks on the wall formed by the above materials. Due to the influence of labor, machinery, materials, and climate, the construction period is often long, and it is difficult to guarantee the progress requirements. , Secondly, the external thermal insulation wall, when using organic thermal insulation materials, also involves fire prevention issues, and many external wall fire accidents have occurred at home and abroad

The construction quality is difficult to guarantee. Common quality problems such as water seepage, falling off, and cracking often occur during use. Some light boards are used for the wall, and the sound insulation effect is extremely poor.
