Problems solved by technology

In the prior art, fasteners are generally used to pass through the outer wall of the surface tube and then directly threaded with the connector. At the same time, the connector is also connected to the column through the fastener. When this structure is used for connection, the gap between the surface tube and the column The connectors between them need to be precisely positioned to be installed. There is no adjustable space, which greatly affects the installation efficiency, and the force at the connection is mainly concentrated on the fasteners, and the stress points of the fasteners are easily affected by shear force Fracture failure, which also reduces the service life of guardrails and protective windows

Embodiment 1

[0034] Figure 1 to Figure 5 Shown is the first embodiment of the assembled guardrail of the present invention. The assembled guardrail includes a surface pipe 1, a column 2 and an expansion joint 3. The bottom of the surface pipe 1 is provided with a groove 11. The expansion joint 3 includes a connecting plate 31 connected to One side of the plate 31 is provided with a first expansion part 32, and the other side is provided with a second expansion part 33, which is simple in structure and easy to install. When assembling, first insert the first expansion part 32 into the column 2, Use the first jacking wire 4 to expand the first expansion part 32 and expand and tighten the inner wall of the column 2 to realize the installation of the expansion joint 3 and the column 2, and then set the second expansion part 33 in the groove 11 , use the second top wire 5 to expand the second expansion part 33 and expand and connect the inner wall of the groove 11, so as to realize the install...

Embodiment 2

[0043] Figure 6 to Figure 9 Shown is the second embodiment of the assembled guardrail of the present invention, the assembled guardrail is the same as the base of Embodiment 1, the only difference is that the first expansion portion 32 includes two first side plates 321, and one end of the first top wire 4 is connected to the A first side plate 321 is threaded, and the other end is offset against another first side plate 321. It has a simple structure and is easy to install. When the first jacking screw 4 is tightened, the two first side plates 321 expand to both sides and The inner wall of the column 2 is connected by expansion and tightening, so as to realize the installation of the expansion joint 3 and the column 2, and also ensure the expansion and tightening effect.

[0044] In this embodiment, a first side plate 321 of the first expansion part 32 is provided with a second threaded hole 3211 that is matched with the first screw 4, and the second threaded hole 3211 enabl...

Embodiment 3

[0046] Figure 10 to Figure 12 Shown is the third embodiment of the assembled guardrail of the present invention, the assembled guardrail is the same as the base of Embodiment 1, the only difference is that the second expansion part 33 includes two second side plates 331, and the two second side plates 331 The end is bent with a lifting plate 333 inclined towards the connecting plate 31, a chute 34 is formed between the two lifting plates 333, the second jacking wire 5 is a bolt, and the second jacking wire 5 is passed through the chute 34 , and the nut end of the second jacking wire 5 is fastened to the lifting plate 333, and the threaded end is threaded to the top surface of the groove 11. Set it in the groove 11, then move along the chute 34 to adjust the expansion joint 3 to the predetermined position, and then tighten the second jacking wire 5, so that the lifting plate 333 expands and connects with the inner wall of the groove 11. On the one hand, the column 2 and the l...

Abstract

The invention discloses an assembled guardrail, which comprises a surface pipe, a column and an expansion joint. The bottom of the surface pipe is provided with a groove, and the expansion joint includes a connecting plate. One side of the connecting plate is provided with a first expansion part, and the other side is provided with a There is a second expansion part, the first expansion part is inserted into the column and connected to the inner wall of the column through the first top wire, and the second expansion part is sleeved in the groove and connected to the groove through the second top wire The inner wall is tightly connected. The assembled guardrail has the advantages of simple structure, good stability, and the ability to realize post-installation of surface tubes.

Description

technical field [0001] The invention mainly relates to pipe connection technology, in particular to an assembled guardrail. Background technique [0002] In fields such as guardrails and protective windows, the connection between the surface pipe and the column needs to be realized through a connecting piece. In the prior art, fasteners are generally used to pass through the outer wall of the surface tube and then directly threaded with the connector. At the same time, the connector is also connected to the column through the fastener. When this structure is used for connection, the gap between the surface tube and the column The connectors between them need to be precisely positioned to be installed. There is no adjustable space, which greatly affects the installation efficiency. Moreover, the force at the connection is mainly concentrated on the fasteners, and the stress points of the fasteners are easily damaged by shear force. Fracture failure, which also leads to short...
