Composite heat-insulating superimposed sheet

Abstract

The invention belongs to the technical field of constructional engineering and discloses a composite heat-insulating superimposed sheet integrated with a concrete body structure. The sheet is characterized in that interface agent protective layers are arranged on both sides of a polystyrene board, bidirectional high-strength steel wires which are inserted obliquely are distributed inside the polystyrene board, and a single side of the polystyrene board is covered by and welded with a steel wire mesh, accordingly, a heat-insulating plate with the whole welding steel wire frame is formed, wherein obliquely-inserted steel wires penetrate through the polystyrene board. The steel wire mesh is wrapped in a light composite concrete layer, the light composite concrete layer is combined with an extruded sheet through an interface agent to form the heat-insulating plate, an anchor bolt hole is arranged on the heat-insulating plate, a counter bored hole is arranged on the light composite concrete layer corresponding to the anchor bolt hole, an anchor bolt is arranged inside the anchor bolt hole, and one end of the anchor bolt extends out of the extruded sheet and the interface agent protective layer and is locked by a nut. The composite heat-insulating superimposed sheet is good in fire safety and capable of simplifying construction procedures, accelerating the construction progress, reducing building costs, achieving industrial production, guaranteeing the quality of all aspects and avoiding hidden quality dangers, such as empty drums, cracks, water seepage and falling-off, caused by complicated operating procedures to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, in particular to a composite thermal insulation laminated board integrated with the concrete of the main structure. Background technique [0002] At present, in domestic industrial and civil construction projects, the external insulation of structural engineering such as frames, bent frames, and shear walls is mostly pasted or sprayed with organic or inorganic insulation materials, such as XPS insulation boards, foam plastics, etc. These methods have many procedures, heavy engineering construction and management tasks, and are prone to problems such as hollowing, cracking, water seepage, and shedding. The external thermal insulation system of the concrete exterior wall has the biggest advantages of pouring the wall insulation together, forming at the same time, fast construction, safety and firmness, but it also has poor fireproof performance because the board surface is not coat...
