A nail bolt

Abstract

The invention relates to a nail bolt. The nail bolt is divided into two parts along the length direction with one part as a long stud and the other part as a threaded stud. The tail end of the long stud is provided with a tip part. The nail bolt is characterized in that the tip part of the long stud is uniformly distributed with retaining pitch threads on which a buffer gasket is arranged. The end part of the screw stud is provided with a dovetail stud head. The end part of the threaded stud is further provided with an ammunition piece seat having a dovetail groove. The dovetail groove matches the dovetail stud head in size. The back end of the ammunition piece seat is provided with an ammunition loading groove. Nitrocotton ammunition pieces are pressed into the ammunition loading groove. The surfaces of the bitrocotton ammunition pieces are coated with glue films used for sealing. The nail bolt has following advantages: the nail bolt is complete in function, convenient in operation, simplified in program, easy in operation and enhanced in efficiency; labor and machinery are saved; electricity is saved and environmental protection is achieved; safety and sanitation are obtained; cost is lowered; and benefits are improved.

Description

technical field [0001] The invention relates to a nail bolt. Background technique [0002] The nail bolt is a special fixing bolt used to fix the hanger on the wall or panel through bolt connection. All kinds of construction and installation projects are used to fix pipelines, pipeline supports, brackets, hangers and equipment on the foundation, walls, floors, columns and ceilings. Generally, this nail bolt method is used for construction. [0003] The nail bolt is generally divided into two parts along its length direction, one part is a long column with a tip at the end of the long column, and the other part is a threaded column, which can be tightened and fitted with a nut. When using the nail bolt, you can use the supporting nailer to shoot the tip of the nail bolt into the wall or the board. Traditional construction operations require power supplies, impact drills, and construction of wrench brackets for construction work. The operator needs to use a percussion drill...

AI Technical Summary

Problems solved by technology

The project operation process is complex and the labor intensity is high

Especially when drilling on the upper part of the ceiling, the impacted concrete dust will fall and fly, deteriorating the working environment and affecting the physical and mental health of the workers

Expansion bolts are used for fixed installation. Operators need to use impact drills and spanners to drill holes, plant bolts, screw nuts to expand, and then install other connecting parts. The construction work is cumbersome, the work efficiency is low, and the construction cost is high.
