Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of easy damage and fracture of the anchor bolts currently used to fix the insulation board in the construction of the insulation wall, and propose an anchor bolt for fixing the insulation board on the wall
Since the end cap 1 and the bolt sleeve 2 are composed of separate parts, it solves the problem of damage and fracture of the outer end cap and the connection between the outer end cap and the bolt sleeve due to hammering during installation

specific Embodiment approach 1

[0005] Specific implementation mode one: the following combination figure 1 Describe this embodiment in detail, this embodiment is made up of end cap 1, bolt sleeve 2 and core rod 3; The end diameter 1-1 is matched and connected, and is axially positioned by the upper end step of the bolt sleeve 2 and the counterbore end face 1-2 at the upper end of the end cap 1. There are multiple surrounding raised bands 3-1 at the lower part of the core rod 3, and the bolt sleeve 2 The outer surface of the lower part has multiple surrounding inverted cone raised bands 2-1, and the lower part of the bolt sleeve 2 has two axially long openings 2-2 which are symmetrical through the pipe wall of the bolt rod. Surrounding the reverse cone raised band 2-1 is evenly distributed on the bolt sleeve 2 at the long opening 2-2. All the parts of the present invention are molded by mold injection using thermoplastic polypropylene material.

specific Embodiment approach 2

[0006] Embodiment 2: In this embodiment, the outer conical step surface 3-2 at the upper end of the core rod 3 is in contact with the inner counterbore step 2-4 at the outer end of the upper end of the bolt sleeve 2 for positioning.

[0007] The installation process of the present invention is as follows: first, the outer surface of the lower part of the bolt sleeve 2 has a plurality of surrounding inverted cone raised bands 2-1 and a bolt end with two symmetrical axially long openings 2-2 penetrating through the wall of the bolt sleeve 2, Penetrate through the inner hole of the outer flat end of the end cap 1, and then pass the lower end bolt sleeve 2 that has penetrated into the end cap 1 through the installation hole of the insulation board and install it into the inner hole of the wall for installation. When the lower end cap 1 When the end face is positioned by the end step of the bolt sleeve 2 and the end face 1-2 of the upper end counterbore of the end cap 1 to achieve a...

Abstract

This invention relates to an anchoring bolt used in the insulation board of the fixed wall. The structure of said invention comprises: the core rod 3 is in the bore 2-3 of bolt sleeve 2; the bore of the end-cap 1 is connected with the diameter of axle 1-1 set in the upper of bolt sleeve 2; the lower of the core rod 3 has several embracing protuberance belts 3-1, and the lower outer surface of the bolt sleeve 2 has several embracing back taper protuberance belts 2-1; the lower of the bolt sleeve 2 has two symmetrical axial long openings 2-2 throughout the pipe wall of bolt sleeve 2. The accessories of said invention are all made of plastic with dies, and the end-cap and bolt sleeve are made up of split units, by which can avoid hurt and fracture in connecting point.

Description

Technical field: [0001] The invention relates to a fastener, in particular to an anchor bolt for fixing a thermal insulation board on a wall. Background technique: [0002] In the field of construction, it is widely used to attach insulation boards to the outside of the main wall before laying tiles, and anchor bolts are used to fasten the insulation board and the wall. Because the end cap of the bolt body and the end of the bolt sleeve are integrally constructed for the anchor bolts commonly used now, the hammering during installation is likely to cause damage and fracture of the outer end cap and the connection between the outer end cap and the bolt sleeve, and the damage and fracture rate is as high as 15~ 20%, which will not only cause a lot of loss and waste, but also have an adverse effect on ensuring the construction quality and progress. And Chinese patent announcement No. 2385127, title is: Disposable countersunk anti-theft expansion bolt, it is to adopt metal mate...
