Prefabricated thermal insulation laminated wallboard with spatial three-dimensional structure and manufacturing method of laminated wallboard

Abstract

The invention relates to construction prefabricated members and manufacturing methods thereof and in particular relates to a prefabricated thermal insulation laminated wallboard with a spatial three-dimensional structure. The prefabricated thermal insulation laminated wallboard comprises a thermal insulation body (2) on the outer layer and a prefabricated laminated wall on the inner layer, wherein the thermal insulation body (2) sequentially comprises an inner reinforcing plate (2a), a thermal insulation layer (2b) and an outer reinforcing plate (2c) from interior to exterior; the inner reinforcing plate (2a) is inwards provided with a three-dimensional fiber rod net rack (1) and is embedded into an outer prefabricated layer (3); the prefabricated laminated wallboard consists of the outer prefabricated layer (3), an outer longitudinally and transversely stressed steel bar plane rack (4), lattice reinforcements (5), an inner prefabricated layer (6) and an inner longitudinally and transversely stressed steel bar plane rack (7); a meshed bracing bar (1b) and a planar mesh fabric (1a) are connected to stretch into the inner reinforcing plate (2a) and are repeatedly inserted into the inner reinforcing plate (2a), the thermal insulation layer (2b) and the outer reinforcing plate (2c) in a large scale; and the thermal insulation layer and the structural layer are connected together through a three-dimensional space structure. The problems of cracks and water leakage of the thermal insulation system are solved, the energy-saving effect is good, the service life of the insulation board is prolonged, and the problem that the outer thermal insulation layer of the outer wall needs to be frequently maintained and replaced is solved.

Description

technical field [0001] The invention relates to a building prefabricated component and a manufacturing method thereof, in particular to a prefabricated thermal insulation wall structure and a manufacturing method thereof. Background technique [0002] With the rapid development of my country's urban construction, building energy consumption has increased year by year, accounting for more than 30% of the total social energy consumption. At the same time, the annual energy consumption of building materials for building construction has also exceeded 15%. Consumption accounted for more than 45% of the country's total energy consumption, has become my country's major energy consumption. my country's existing construction area has exceeded 40 billion m 2 , Most of them are high-energy buildings, and the huge energy consumption of buildings has become an important restrictive factor restricting my country's economic development. Therefore, since 1997, the state has enforced the 5...

AI Technical Summary

Problems solved by technology

The thermal insulation performance of the wall is greatly affected by the worker's operation level. If the worker's operation is not in place, the thermal insulation layer may crack, hollow, etc., and even fall off in severe cases, affecting building safety and thermal insulation and energy saving.

In addition, on-site insulation materials construction is easily restricted by climate and seasons, which affects the overall construction progress; when insulation materials are transported to the site, a special area needs to be set up to place them, which increases on-site management costs
