Installing fixing device for outer wall heat-insulation plate

Abstract

The invention discloses an installing fixing device for an outer wall heat-insulation plate, which comprises a tabletting piece, a wall fixing piece and a connecting piece, wherein the tail of the tabletting piece is provided with a pressing piece perpendicular to a body, and the head of the tabletting piece is provided with a fixing limiting hole. One end of the connecting piece is provided with an external thread, the other end of the connecting piece is provided with a slot in the axial direction, the slot divides the end into at least two elastic pieces, the outer surface of each elastic piece are axially respectively provided with a barb-shaped protrusion matched with the fixing limiting holes. The head of the wall fixing piece is provided with an expansion slit, the end face of the tail of the wall fixing piece is provided with an internal thread, and a bottom wall of an internal thread hole is provided with a fixing hole communicated with the expansion slit, and the fixing piece further comprises an expansion pin capable of being inserted into the fixing hole. Due to the fact that the tabletting piece is pre-embedded in the heat-insulation plate, strength of the heat-insulation plate is greatly improved. Simultaneously, the fact that the heat-insulation plates are positioned on the same horizontal plane during installation is guaranteed, the outer surfaces of the heat-insulation plates do not need to be damaged, and the wall surface is more attractive after installation.

Description

technical field [0001] The invention relates to an installation and fixing device for an external wall insulation board, which belongs to the field of building materials. Background technique [0002] In recent years, the country requires buildings to be energy-saving and environmentally friendly, which has upgraded the requirements for environmental protection and energy conservation. Now more and more buildings are covered with a layer of thermal insulation material on the exterior walls, but the existing exterior wall renovations have no effect on the original walls. There is damage, and a lot of dust and noise will be generated during the construction process, and the process is also complicated. [0003] In the current market, the insulation material commonly used is insulation board. Most of the installation process is to glue the wall and insulation first, then drill the wall and insulation board, and fix the insulation board to the wall with expansion bolts. The exp...

Problems solved by technology

[0004] However, the following problems will occur in this type of installation process: 1) The insulation board is directly attached to the original wall surface, and it is impossible to realize that the insulation board on the entire wall can be on the same plane, which affects the appearance; In the process, it is necessary to drill holes in the insulation board, which will damage the outer surface of the insulation board, affect the appearance, and also increase the water seepage points of the outer wall
