Extending-bulging type glue fixing nail and use method

Abstract

The invention relates to an expansion adhesive fastening nail and a use method thereof, wherein the expansion adhesive fastening nail consists of a big-end tube expansion nail, an expansion sleeve, a hanging piece head and adhesive; the big-end tube expansion nail (1) is matched with the expansion sleeve (9) and is fixed with a wall body; an expansion plate (12) expands to exceed the nail head of the big-end tube expansion nail (1) and splits into the shape of petals; the nail head of the big-end tube expansion nail (1) is clamped at a petaloid bottom to increase pulling resistant and shear resistant; therefore, the nail is particularly suitable to install various equipment and veneers on floppier wall bodies such as an autoclaved aerated concrete wall body, thereby ensuring the longtime safety and steadiness of a project; moreover, the member saves raw material and reduces cost along with a reasonable and convenient use method. Obviously, the nail and the method have high use value and enormous social benefits and economic benefits.

Description

technical field [0001] The invention relates to a building component and its use method, in particular to an expansion-type adhesive nail and its use method. technical background [0002] At present, in the installation of various equipment and decorative panels on the wall, the steel frame dry hanging method, the back bolt dry hanging method, etc. are mostly used, and the steel frame keel is required as the main body of the force, but due to the corrosion of steel and the high cost , so it has its limitations. Therefore, in recent years, no steel frame is needed as the keel, and the low-cost nail-planting anchor point hanging method is very popular with builders. Yet the used hanging nail of this method is to be fixed with the hole on the body of wall with bonding agent, because the decorative panel can be installed only after the bonding agent is fully cured, so can influence project progress. In addition, due to the limited pull-out resistance of the hanging nail itself...

AI Technical Summary

Problems solved by technology

However, the nails used in this method are fixed with the holes on the wall with an adhesive, and the decorative panel can only be installed after the adhesive is fully cured, so it will affect the progress of the project.

In addition, due to the limited pull-out resistance of the hanging nail itself, it is not ideal for softer walls such as autoclaved aerated concrete, so this method still needs to be improved.
