Outer wall stone heat preservation decorative one-piece board

Abstract

The one-piece board of the invention relates to a heat preservation decorative material for building external walls. The one-piece board of the invention is composed of an ultrathin natural stone with a thickness of 7+ / -1 mm and a hard bubble polyurethane thermal insulation material, and the periphery and the back side of the one-piece board are packed by a high pressure cement fibrolite plate serving as a fireproof frame. Firstly, natural stone is processed into the ultrathin natural stone with a thickness of 7+ / -1 mm, a dovetail groove is arranged at the back of the ultrathin stone and one centimetre-width thicknessing processing is carried out at the periphery of the back of the ultrathin stone to facilitate the installation of the fireproof frame; and then, the high pressure cement fibrolite plate and the ultrathin stone are put into a prefabricated mould and the polyurethane serving as the thermal insulation material is injected into the mould by a machine. In the invention, the stone with a thickness of 7+ / -1 mm is adopted to solve the problem that the traditional hang stone with a thickness of 2.5 centimetres bears the weight of the wall; in addition, the one-piece board integrates fire proofing and decoration, and a decorative surface is completed by one-off construction, which accelerates on-site construction speed and construction security; each piece of the thermal insulation material is a totally-enclosed independent whole, so that the thermal insulation material is more durable.

Description

Technical field: [0001] This product belongs to the field of building exterior wall insulation and energy-saving building materials Background technique: [0002] At present, the commonly used building exterior wall decoration is made of stone curtain wall and exterior wall insulation system. The insulation board is first pasted on the surface of the exterior wall, and then the 2.5 cm thick stone decoration surface is hung with channel steel and angle steel. It is completed in two different processes. , this type is not only costly, but also slow in construction speed, the quality of on-site construction cannot achieve the best results, and often due to some human factors such as electric welding, unextinguished cigarette butts, etc. when the stone is dry-hanging on site, the insulation board is ignited, and many losses are heavy. Fires are caused by this. This product combines the two products of stone and thermal insulation and the construction process into one, factory-p...
