Construction preburied member for compound thermal insulation wall and method of use thereof

Abstract

The invention relates to a construction embedded part used in external wall thermal-insulation composite wall and a usage of the construction embedded part. The construction embedded part comprises a bolt or a screw used for fixing ornaments on the decoration surface of the external wall and a sleeve used for fixing and clamping the bolt or the screw. Threads matching with the bolt are arranged in the sleeve, or a structure which can clamp the screw is filled in the sleeve. A base disk, the diameter of which is larger than that of the sleeve, is blocked in the outer end opening of the sleeve; a clamping disk, the diameter of which is larger than that of the sleeve and the position of which is adjustable, is blocked at the waist part of the sleeve; and the base disk and the clamping disk work together to fix the embedded part on a thermal-insulation layer. The technical characteristics of the embedded expansion bolt strengthens the connecting effect of the composite wall, reduces, even avoids the loose and displacement caused by the impact of the falling concrete during the process of pouring; and the embedded expansion bolt also simplifies the difficulty of the construction and reduces the cost of equipment.

Description

technical field [0001] The invention relates to a component and a use method of an external thermal insulation composite wall, in particular to a construction embedded part used in a pouring external thermal insulation composite wall in a construction project and a usage method thereof. Background technique [0002] The form of external wall insulation is increasingly used in construction projects. The so-called external insulation of the wall means that the insulation layer is located on the outdoor surface of the wall instead of the indoor surface. In the past, the connection form of the external insulation layer of the poured external wall and the wall was usually directly bonded with an adhesive. Smaller, and the insulation layer directly bears the load of the exterior finish, and its bearing capacity is limited, so usually only the exterior finish of polymer mortar can be used, and generally it cannot be pasted with wall tiles and other facing materials, and the above-m...

Problems solved by technology

[0004] However, the defect and deficiency of this prior art is that the plug-in body inserted into the insulation layer will inevitably be impacted by falling cement during the pouring of cement, resulting in loosening and displacement. The positioning bayonet is fixed and equipped with a plug-in plate to reduce the impact of the cement, but it undoubtedly increases the difficulty of construction and the cost of the equipment; at the same time, the stroke of the bolt is short, and there is little room for adjustment in the next construction; Yes, the structure and processing of the connector assembly are complicated, and the manufacturing cost is relatively high
