Problems solved by technology

The traditional expansion anchor has the following disadvantages. First, the opening end of the expansion sheet is inward after expansion, and the anti-off effect is poor; second, it can only be used alone and cannot be used in combination, and the scope of use is small; third, after installation, the outside will be exposed. One end affects the overall appearance

Embodiment 1

[0013] Such as figure 1 As shown, a combined expansion anchor bolt is composed of expansion tube (1), connecting body (2) and tapered plug (3). When in use, expansion tube (1), connecting body (2) and tapered plug (3) connected sequentially as one. The outer diameter of the expansion tube (1) is consistent with the outer diameter of the connecting body (2), and a symmetrical strip-shaped opening is provided at the rear of the expansion tube (1), so that the upper part of the expansion tube (1) is divided into two symmetrical parts , good expansion effect. The connecting body (2) is composed of a terminal (21), a cone (22), a cylindrical body (23) and an expansion part (24) from front to back, the terminal (21) is cylindrical, and the terminal (21) The diameter is equal to the inner diameter of the expansion tube (1), which not only can increase the contact area between the connecting body (2) and the expansion tube (1), but also has a guiding effect. The diameter of the fro...

Embodiment 2

[0015] Such as figure 2 As shown, a combined expansion anchor bolt is composed of expansion tube (1), connecting body (2) and tapered plug (3). When in use, the expansion tube (1), connecting body (2) and tapered plug (3) Connected sequentially into one body, wherein one expansion tube (1) and a tapered plug (3) are provided, and at least two connecting bodies (2) are provided. The outer diameter of the expansion tube (1) is consistent with the outer diameter of the connecting body (2), and a symmetrical strip-shaped opening is provided at the rear of the expansion tube (1), so that the upper part of the expansion tube (1) is divided into two symmetrical parts , good expansion effect. The connecting body (2) is composed of a terminal (21), a cone (22), a cylindrical body (23) and an expansion part (24) from front to back, the terminal (21) is cylindrical, and the terminal (21 ) is equal to the inner diameter of the expansion tube (1), which not only can increase the contact...

Abstract

The invention relates to a combined expansion anchor bolt. The combined expansion anchor bolt consists of an expansion pipe, a connecting body and a conical plug; and the expansion pipe, the connecting body and the conical plug are connected as a whole in sequence in use, wherein one expansion pipe and one conical plug are provided, and at least one connecting body is provided. The combined expansion anchor bolt has the beneficial effects of reasonable structure, high pulling resistance, good fall preventing effect and capability of fixing multiple layers of materials. The combined expansion anchor bolt can be singly used or used through combining, and is wide in application range. The combined expansion anchor bolt only needs to be hammered in, and is convenient for construction, fast, economical and safe.

Description

Technical field: [0001] The invention relates to an anchor bolt, in particular to a combined expansion anchor bolt. Background technique: [0002] Expansion-type anchor bolts use expansion parts to squeeze the wall of the anchor hole to form anchor bolts for anchoring. It is a component that uses the relative movement of the vertebral body and the expansion sheet to promote the expansion of the expansion sheet, generate expansion agent pressure with the concrete of the hole wall, and generate pull-out force through shear friction to anchor the connected parts. The traditional expansion anchor has the following disadvantages. First, the opening end of the expansion sheet is inward after expansion, and the anti-off effect is poor; second, it can only be used alone and cannot be used in combination, and the scope of use is small; third, after installation, the outside will be exposed. One end affects the overall appearance. 4. Each expansion anchor bolt has only one expansion...
