Problems solved by technology

In the prior art, fasteners are generally used to pass through the outer wall of the surface pipe and then directly threaded with the corner joint. When this structure is used for connection, precise positioning is required between the surface pipe and the corner joint to achieve installation, and there is no room for adjustment. It greatly affects the installation efficiency, and the stress at the connection is mainly concentrated on the fasteners, and the stress points of the fasteners are easily broken by shear force and fail, which also shortens the service life of guardrails and protective windows

Embodiment 1

[0035] Figure 1 to Figure 6 It shows the first embodiment of the surface tube assembly used for guardrails in the present invention, which includes a surface tube 1 and an expansion joint 2. The surface tube 1 is provided with a groove 11 at the bottom, and its structure is simple, easy to install, and easy to assemble. , insert the two ends of the expansion joint 2 into the grooves 11 of the two surface pipes 1 respectively, and then use the fastener 3 to connect the two ends of the expansion joint 2 to the two surface pipes 1 respectively, so as to realize The pre-installation of the expansion joint 2 and the two surface pipes 1, when the fastener 3 is further tightened, the expansion joint 2 expands and respectively expands and connects with the inner walls of the grooves 11 of the two surface pipes 1, thereby realizing installation. In terms of traditional direct screw connection, the expansion joint 2 can be adjusted by sliding in the groove 11, that is, the connection p...

Embodiment 2

[0043] Figure 7 to Figure 11 It shows the second embodiment of the surface pipe assembly used for the guardrail of the present invention. This assembly is basically the same as Embodiment 1, the only difference is that the fastener 3 is a jacking thread, and one end of the fastener 3 is screwed to the bottom plate 211 , the other end is against the two folded plates 213, and the jacking force of the fastener 3 makes the two folded plates 213 expand. The structure is simple and easy, and when the fastener 3 is tightened, the fastener 3 The end drives the folding plate 213 to expand and drives the side plate 212 to expand to both sides to expand and connect with the inner wall of the groove 11. It is effectively shared with the side plate 212 to strengthen the connection effect, and this structure does not need to open holes on the surface pipe 1 , which improves the load-bearing strength of the surface pipe 1 .

[0044] In this embodiment, the bottom plate 211 is provided wit...

Embodiment 3

[0046] Figure 12It shows the second embodiment of the surface pipe assembly used for the guardrail of the present invention. This assembly is basically the same as Embodiment 1, the only difference is that the two sockets of the decorative shell 4 are perpendicular to each other, so that the two The plug-in end of the surface pipe 1 can always be covered by the decorative shell 4 without setting an inclined surface, and it can also ensure that the two surface pipes 1 are also perpendicular to each other. It is suitable for the corner of the guardrail. Its structure is simple, beautiful and durable.

Abstract

The invention discloses a surface tube assembly for a guardrail, which comprises a surface tube and an expansion joint. The surface tube is provided with a slope at one end, and the bottom of the surface tube is provided with a groove. The ends are respectively inserted into the grooves of the two surface pipes, and the two surface pipes are butted on the inclined surface. Fasteners are installed on the expansion joints. The inner wall of the groove of the surface pipe is tightly connected. The surface pipe assembly has the advantages of simple structure, convenient installation and effective improvement of connection strength.

Description

technical field [0001] The invention mainly relates to pipe material connection fittings, in particular to a surface pipe assembly for a guardrail. Background technique [0002] In fields such as guardrails and protective windows, the surface pipes at the corners are generally connected through corner joints. In the prior art, fasteners are generally used to pass through the outer wall of the surface pipe and then directly threaded with the corner joint. When this structure is used for connection, precise positioning is required between the surface pipe and the corner joint to achieve installation, and there is no room for adjustment. The installation efficiency is greatly affected, and the stress at the joint is mainly concentrated on the fasteners, and the stress points of the fasteners are easily broken by shear force and fail, which also leads to shortened service life of guardrails and protective windows. Contents of the invention [0003] The technical problem to be...
