Problems solved by technology

[0002] Existing guardrail structures such as Figure 5 As shown, it includes two upper and lower horizontal tubes and multiple grid tubes connected between the two horizontal tubes. The end of the grid tube is connected to an L-shaped connecting piece by screws, and the other wall of the L-shaped connecting piece is screwed Connected to the horizontal pipe, so the installation is troublesome and inefficient and the connection strength is not high

Embodiment Construction

[0016] A detailed description will be given below of specific embodiments of the present invention according to the accompanying drawings.

[0017] according to Figure 1 to Figure 4 As shown, a spliced ​​guardrail described in this embodiment includes a horizontal tube 1 with two side openings, a plurality of grid tubes 3 that are slidably connected to the openings of the two horizontal tubes, and buckled with the openings of the horizontal tubes. There are a plurality of positioning pieces 2, and the positioning pieces are located between every two adjacent grid tubes.

[0018] The horizontal tube 1 includes an outer tube body 11 with a rounded rectangular end face, a transverse support arm 13 integrally connected between the two short side walls of the outer tube body, and a horizontal support arm 13 integrally connected between the two long sides of the outer tube body. The two longitudinal support arms 12 between the walls are integrated at the intersection of the longit...

Abstract

The invention discloses a spliced-type guardrail which comprises a cross pipe with two lateral openings, multiple grid pipes in slidable fit connection with the two openings of the cross pipe, and multiple positioning members in buckled connection with the openings of the cross pipe. Each positioning member is positioned between each two adjacent corresponding grid pipes, the cross pipe comprises an outer pipe body, a transverse supporting arm and two longitudinal supporting arms, one end of the outer pipe body is in the shape of a rounded rectangle, the transverse supporting arm is integrally connected between two short-side wall faces of the outer pipe body, the longitudinal supporting arms are integrally connected between two long-side wall faces of the outer pipe body, the openings are formed in one of the long-side wall faces of the outer pipe body and positioned between the longitudinal supporting arms, and two buckling connection walls are formed in a portion, between the longitudinal supporting arms and the openings, of the outer pipe body. After the grid pipes are slidably connected on the buckling connection walls on the cross pipe, the cross pipe is matched with the positioning members to clamp the grid pipes, in other words, the grid pipes are completely fixed to the cross pipe, other connecting members and tools are not needed for operation, and the spliced-type guardrail is convenient and quick to mount and high in connecting strength.

Description

technical field [0001] The invention belongs to the field of metal guardrail structures, and in particular relates to a spliced ​​guardrail structure. Background technique [0002] Existing guardrail structures such as Figure 5 As shown, it includes two upper and lower horizontal tubes and multiple grid tubes connected between the two horizontal tubes. The end of the grid tube is connected to an L-shaped connecting piece by screws, and the other wall of the L-shaped connecting piece is screwed Connected to the horizontal pipe, the installation is troublesome, the efficiency is low and the connection strength is not high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a spliced ​​guardrail structure that is easy to install and has a firm structure after installation, aiming at the deficiencies in the prior art. [0004] In order to achieve the purpose of the present invention, the following technical so...
