Insulation superimposed plate and construction method

Abstract

The invention discloses an insulation superimposed plate and a construction method. The insulation superimposed plate is characterized in that embedded nylon parts and supporting and pulling rods are arranged, the embedded nylon parts are provided with connecting rods and connecting discs, connecting grooves are formed in the end faces of the connecting discs, one end of each connecting rod is connected to the corresponding connecting disc, a threaded hole is formed in the other end of each connecting rod, the connecting rods penetrate through an extruded sheet and an adhesion agent layer and stretch out, the connecting discs are clamped on a steel wire mesh through the connecting grooves, the connecting discs and parts of the connecting rods are wrapped in a concrete layer, the supporting and pulling rods are steel ribs and are connected with the connecting rods through threads, and hooks are arranged at the other ends of the supporting and pulling rods. The construction method comprises the steps that insulation superimposed plates are spliced into a part with the size identical with beams, columns and shear force of a frame of an external wall part and are combined with formworks to form a mould, the supporting and pulling rods abut against the corresponding formworks, concrete is poured into the mould, the formworks are then demounted, and the insulation superimposed plates and the concrete form a whole. Construction is convenient and low in cost, and the potential quality hazards such as bulging, cracking, water seepage and disengagement caused by complex operation processes can be avoided to the maximum.

Description

technical field

[0001] The invention belongs to the technical field of construction engineering, and in particular relates to a thermal insulation laminate integrated with the concrete of the main structure and a construction method thereof. 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 pasting XPS insulation boards, spraying polyurethane foam, 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. Polystyrene foam plastic board cast-in-place concrete external wall external insulation system and steel wire grid polystyrene foam plastic board cast-in-place concrete external wall external thermal insulation system, the insulatio...
