Description

Expansion anchor bolt for installation of heat-insulating wall board

Technical Field

The utility model relates to a fastener technical field for the building especially relates to an expansion anchor bolt is used in installation of heat preservation wallboard.

Background

Modern buildings have higher and higher requirements on energy conservation, and generally require a layer of heat-insulating wall board to be additionally arranged on an outer wall, so that a large number of expansion anchor bolts are required to be used for installing and fixing the heat-insulating wall board. At present, after the insulation board is firmly bonded, a hole is drilled by using a percussion drill at the position required by design, an expansion anchor bolt is driven into the expansion anchor bolt by using a rubber hammer, an anchoring nail is screwed into the expansion anchor bolt, and after the anchoring nail is screwed into the expansion anchor bolt, the anchoring nail is knocked to ensure that the expansion part of the expansion anchor bolt expands outwards so as to be fixed in the hole.

The traditional expansion anchor bolt pipe is easy to deform, and the problem of easy damage of extreme load during use is solved; the long-strip-shaped gap of the expansion part is cracked, and when the expansion part expands outwards, the long-strip-shaped gap is easy to crack axially, so that the expansion stress is uneven, and the fastening strength is influenced; in addition, when anchor nail and wall connection intensity were not enough, the expansion anchor bolt was become flexible outwards to be shifted out, so, need to fasten again, work efficiency is low, take a lot of work, waste material, comprehensive cost height.

Disclosure of Invention

An object of the utility model is to overcome the not enough of above-mentioned technique, provide an expansion anchor is used in the installation of heat preservation wallboard that simple structure, structural strength are high, fastening strength is high.

In order to realize the purpose of the utility model, the utility model adopts the technical scheme that: an expansion anchor bolt for installing a heat-insulating wall plate comprises a disc and an anchor bolt pipe vertically arranged in the center of the disc, wherein the center of the disc is provided with a through hole communicated with the inner cavity of the anchor bolt pipe, and the diameter of the through hole is equal to the inner diameter of the anchor bolt pipe; the anchor bolt tube is characterized in that the anchor bolt tube is sequentially divided into an extrusion section, an expansion section and a non-expansion section from the head part to the tail part, and the anchor bolt tube of the extrusion section is in a frustum-shaped structure with gradually expanded diameter along the direction from the head part to the tail part; the anchor bolt pipe of the expansion section is a zigzag threaded pipe, a plurality of strip-shaped gaps are formed in the length direction of the pipe wall of the anchor bolt pipe of the expansion section, the strip-shaped gaps are uniformly distributed at intervals along the circumferential direction of the anchor bolt pipe, and reinforcing rib rings are further arranged on the pipe walls at the two ends of the strip-shaped gaps; and a plurality of barbs which are arranged in a staggered manner are arranged on the outer wall of the anchor bolt pipe of the non-expansion section.

Furthermore, a reinforcing rib is connected between the outer wall of the anchor bolt tube of the non-expansion section and the disc, so that the structural strength of the expansion anchor bolt is improved.

Furthermore, 4 strips are arranged in the strip-shaped gap.

Further, the length of the extrusion section < the length of the expansion section < the length of the non-expansion section.

Furthermore, the long-strip-shaped gap penetrates through the pipe wall, so that the pipe cavity of the anchor bolt pipe is communicated with the outside of the pipe.

Further, the disc, the anchor bolt tube, the reinforcing rib ring, the barbs and the reinforcing ribs are formed into an integrated structure through injection molding.

The utility model has the advantages that: the expansion anchor bolt provided by the utility model adopts the reinforcing rib ring to ensure that the strip-shaped gap can not extend and crack towards the two ends, and in addition, the problem of insufficient fastening strength of the traditional expansion anchor bolt is solved through the barbs arranged in a staggered way; the expansion anchor bolt has simple structure and convenient use, can effectively anchor and is suitable for the installation and fixation of various heat-insulating wallboards.
