The invention discloses an expansion bolt and wall hole connecting system which comprises an expansion bolt and a wall hole and further comprises a glue injection layer, wherein the glue injection layer is positioned between the expansion bolt and the wall hole. The invention further provides a forming method of the expansion bolt and wall hole connecting system. The forming method comprises the following steps: step A, drilling the wall hole in a wall body required to be positioned by using an impact drill; step B, cleaning residues in the wall hole; step C, pouring glue a into the wall hole; step D, hitting the expansion bolt into the wall hole; step E, before the glue a is dry, tightening a nut on the expansion bolt by using a wrench, so that the bolt moves outwards, and an expansion pipe is immobile; consequently, a large head at the bottom of the bolt expands the expansion pipe and breaks a film layer of a glue containing chamber in an extruding way, so that glue b in the glue containing chamber flows out and is mixed with the glue a. The expansion bolt and wall hole connecting system and the forming method thereof have the benefits that as the glue injection layer is arranged between a traditional expansion pipe and concrete, the connection is firmer; as the glue injection layer has a certain elasticity, the vibrating force can be borne.
Description
technical field [0001] The invention relates to a bolt, in particular to a tension bolt used for fixing walls. Background technique [0002] Explosion bolt principle: Explosion bolt fixing principle: The expansion screw is fixed by using the slope of the pull-out shape to promote the expansion to generate friction and grip force to achieve the fixing effect. One end of the screw is threaded and the other end has a degree of taper. There is an iron sheet on the outside, and there are several cuts in the half of the iron sheet cylinder. Put them together into the hole punched in the wall, and then lock the nut. The nut pulls the screw outward, and pulls the vertebra into the iron sheet cylinder. The iron sheet cylinder is expanded. Open, so it is tightly fixed on the wall, generally used for fastening of guardrails, awnings, air conditioners, etc. on cement, bricks and other materials. But its fixation is not very reliable. If the load has a large vibration, it may loosen, s...
