An ultra-thin stone facing heat preservation system and its manufacturing method

Abstract

An ultra-thin stone facing heat preservation system is composed of a plurality of ultra-thin stone facing heat preservation boards. It includes a stone veneer layer and an insulation board, the backboard bonding layer is formed by bonding material between the stone veneer layer and the insulation board, and a reinforcement layer is arranged inside the backboard bonding layer; the insulation board is a special-shaped insulation board , on the surface of the special-shaped insulation board close to the stone veneer layer, there are several grooves distributed in a staggered manner, and the bonding material filled in the grooves is cured to form ribs; at the intersection of the grooves, there are cantilever beams A mold cavity, a U-shaped steel bar is arranged in the cantilever mold cavity, and the closed end hook of the U-shaped steel bar is set on the reinforcement layer. The external wall thermal insulation system composed of the invention is firmly and safely connected between the ultra-thin stone-faced thermal insulation board and the wall, between the thermal insulation material and the stone decorative board, and between the ultra-thin stone-faced thermal insulation boards in the system. Reliable and long service life. At the same time, the thermal insulation system realizes the overall rigid connection, which solves the bonding and fire prevention problems between the stone veneer layers.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation decoration, in particular to an external thermal insulation decorative surface of an external wall and a manufacturing method thereof. Background technique [0002] With the increasing shortage of energy in the world, the requirements for the thermal insulation performance and fireproof function of building walls are also constantly improving. Different material insulation layers and fireproof finishing layers are installed on the outside of building walls to improve its thermal insulation, System safety performance such as fire prevention and reducing energy consumption have become a common technical measure. Among them, the thermal insulation and decoration integrated board composed of thermal insulation materials and decorative materials has gradually become the mainstream of the market. It is derived on the basis of the national standard JG149-2003 of "Expanded Polystyrene ...

AI Technical Summary

Problems solved by technology

[0003] However, in practical applications, most manufacturers can only simply paste and compound thermal insulation materials and decorative materials to form an external thermal insulation system for the outer wall, and apply a layer of organic waterproof material without fireproof function on the joint between the thermal insulation board and the thermal insulation board.

This kind of external thermal insulation board has many technical defects in terms of thermal insulation structure and connection methods. Taking the integrated thermal insulation and decoration board as an example, the anchor point fixed on the outer wall is set at the edge of the integrated board. Since the edge is the weakest link , easy to break during construction, increasing the difficulty of construction

The thermal insulation and decoration integrated board uses its thermal insulation material as the main body of the supporting member. Since the thermal insulation layer is mostly polymer materials such as polystyrene boards, it is easy to age and burn. After the aging and deterioration of the thermal insulation material loses its strength, it will damage the decorative layer. , resulting in quality problems and safety hazards such as cracks, seepage, leaks and fires in the external thermal insulation system of the external wall.

If natural thin stone is used for the decorative surface, since the thickness of thin stone is generally 8-12 mm, the integrated board of this natural stone exceeds the national standard, which is unsafe and difficult to install and construct.
