Reinforced chemical anchor bolt

Abstract

The invention discloses a reinforced chemical anchor bolt. The reinforced chemical anchor bolt comprises an anchor rod and an elastic anchor strip which is arranged on the front portion of the anchor rod, an installation groove or an installation hole is formed in the front portion of the anchor rod, the elastic anchor strip is positioned and arranged on the front portion of the anchor rod through an installation groove or an installation hole, the elastic anchor strip comprises a branch strip arranged outside the anchor rod, the side portion of the anchor rod is further provided with a folding groove or a folding face, the folding groove or the containing face is matched with the branch strip, the branch strip extends outwards on the side face of the anchor rod and elastically expands and is folded in the folding groove or the folding face on the side portion of the anchor rod under the action of external force, and the branch strip is folded towards the rear end of the anchor rod; during installation, due to the fact that force is exerted on the peak of the anchor rod and no force is exerted on the center of the elastic anchor strip, the elasticity of the elastic anchor strip is guaranteed; due to the fact that the branch strip of the elastic anchor strip is folded elastically during installation, the branch strip is prevented from being excessively exposed out of the anchor rod, the anchor bolt is particularly suitable for the condition that anchor eyes are small, the anchor bolt can be matched with anchor eyes with different sizes more easily, and the universality is higher.

Description

technical field [0001] The invention relates to an anchor bolt structure, in particular to a reinforced chemical anchor bolt. Background technique [0002] The insulation layer of building walls, curtain walls, and architectural decoration fields such as lamps, plumbing, and communications require post-anchoring technology, and mechanical anchors and chemical anchors are usually used. [0003] Due to the expansion sleeve of the mechanical anchor bolt, during the construction and installation process, the corresponding anchor hole should be opened much larger than the rod body, which greatly increases the difficulty of construction for workers, especially when opening holes in reinforced concrete walls. The larger the hole, not only The difficulty of drilling is increased, and the probability of hitting the steel bar is enlarged. When the steel bar is hit, the hole can only be re-drilled, which greatly increases the difficulty of construction, and the cost of mechanical ancho...

Problems solved by technology

[0004]Chemical anchor bolts usually consist of a threaded rod and adhesive hose, for example, a high-strength chemical anchor bolt provided by Chinese patent CN2804455Y, which is completely glued It is anchored by consolidation effect, but its service life is greatly limited, because the life of the adhesive is short, once the adhesive loses its performance over time, all chemical anchor bolts become vacant, which is for the people. The life and property bring great hidden danger
