Description

Expansion screw bolt of double expansion sleeve pipe and manufacture method thereof

Technical field

The invention provides a expansion screw bolt of double expansion sleeve pipe and manufacture method thereof, belong to architectural hardware fastening piece manufacturing technology field.

Background technique

Present employed EXPANSION ANCHOR BOLTS basically by: the conical head bolt is joined the structure of expansion sleeve, plain washer, spring pad and a hexagon nut and is formed.Be used for installing and fixing on concrete foundation or the wall various support elements and equipment, but because perforated brick, hollow brick, concrete hollow block, applying of light aggregate concrete or air-entrained concrete building block masonry new material new technology new structure, re-use above-mentioned this EXPANSION ANCHOR BOLTS, on the wall of above-mentioned masonry structure, install and fix various support elements and equipment and short EXPANSION ANCHOR BOLTS body will occur, after tightening hexagon nut, the bolt head that protrudes metope up and down or about occur tilting, long EXPANSION ANCHOR BOLTS body is tightened hexagon nut in hole after, the phenomenon that the body of bolt continues to go out also can take place in the bolt head that metope is protruded in pulling, influences the fastening quality of various support elements and equipment and body of wall.

Summary of the invention

Problem to be solved by this invention is that a expansion screw bolt of double expansion sleeve pipe and manufacture method thereof are provided.This product is structure and the specification of manufacturing according to various hollow brick and concrete hollow block, invents in conjunction with the characteristics of existing EXPANSION ANCHOR BOLTS.Its principle of work and power is: expansion screw bolt of double expansion sleeve pipe is by the boring hole, pass hollow brick or concrete holllow building block wall surface, make the notch portion that expands arrive at hollow brick, or concrete hollow block interlayer wall inboard, tighten hexagon nut, 2 expansion sleeves are subjected to the pressure of screw rod, impel the notch portion that expands to depend on conical expansion pad and conical head, progressively form twice stubble in an opposite direction to expansion everywhere, stubble is stuck in hollow brick or concrete hollow block outer wall inboard and the interlayer wall inboard separately in an opposite direction.Expansion screw bolt of double expansion sleeve pipe self is subjected in hole under the compressing quick-fried outside the bloated mouthful twice on conical expansion pad and the conical head, will be fastening voluntarily.Because hollow brick, or concrete holllow building block wall will install the position of EXPANSION ANCHOR BOLTS, the state imprevision of masonry structure, and this product is provided with two patterns of Fig. 1 Fig. 2 and selects use for the workmen according to the position and the characteristics of construction.Wherein Fig. 2 is provided with and reconciles the pipe pad circle, and the position of pipe pad circle is reconciled in transposing between 2 expansion sleeves, just can change the spacing of expand mouthful residing position and two expansion sleeves.The function of use of adjutage packing ring allows the oral area position of expanding exactly, same as far as possible hollow brick, or the outer wall of concrete hollow block is inboard and the inboard intimate contact of interlayer wall.Strengthen the fastening effect of expansion screw bolt of double expansion sleeve pipe and body of wall, improve the fastening quality that installs and fixes various support elements and equipment.This product is applicable to perforated brick, hollow brick, installs and uses on the body of wall of the masonry structure of concrete hollow block, light aggregate concrete or air-entrained concrete building block.
