Description

Technical Field

[0001] The present application relates to the technical field of bridge guardrails, and in particular to a bridge guardrail structure that is easy to assemble. Background Art

[0002] Bridge guardrails refer to guardrails installed on bridges. Their purpose is to prevent out-of-control vehicles from going over the bridge. They have the functions of preventing vehicles from breaking through, passing under, or climbing over the bridge and beautifying the bridge structure. Existing bridge guardrails are generally fixed directly on the bridge deck by bolts. This method is not only time-consuming and labor-intensive, but also inconvenient for later disassembly and maintenance. To this end, the inventor proposed a bridge guardrail structure that is easy to assemble. Utility Model Content

[0003] The purpose of the present application is to provide a bridge guardrail structure that is easy to assemble and can improve the convenience of disassembly and assembly on the bridge deck.

[0006] The present application makes the installation of the guardrail and the support plate easier by plugging and matching the guardrail with the sleeve and the limit plate with the embedded pipe. The well-designed positioning bolt is screwed into the positioning tube, which can restrict the limit plate inside the embedded pipe, thereby ensuring the stability of the support plate when installed in the embedded pipe.

[0007] In an optional embodiment, the positioning tube is coaxially arranged with the embedded tube.

[0008] In an optional embodiment, the positioning tube is fixed to the bottom of the embedded pipe.

[0011] In an optional embodiment, the axial length of the limiting plate is greater than the length of the positioning tube.

[0012] In an optional embodiment, the support plate is configured to be in an arc shape coaxially arranged with the limiting plate.

[0013] In an optional embodiment, the support plate and the limiting plate are an integrally formed structure.

[0014] In an optional embodiment, the sleeve is arranged along the radial direction of the support plate.

[0015] In an optional embodiment, both ends of the guardrail are inserted into the sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example 1

[0029] See also Figure 1-Figure 2 This embodiment provides a bridge guardrail structure that is easy to assemble to solve the problem that the existing guardrail is inconvenient to disassemble and assemble due to the bolted installation method.

[0030] In this embodiment, a bridge guardrail structure that is easy to assemble includes a support plate 10, a guardrail 20 and an embedded pipe 30, wherein a sleeve 11 for plugging in with the guardrail 10 is provided on the side wall of the support plate 10, a limiting plate 12 for plugging in with the embedded pipe 30 is provided on the bottom of the support plate 10, a positioning cylinder 31 is provided inside the embedded pipe 30, a positioning bolt 32 is screwed into the positioning cylinder 31, and a bolt head 33 of the positioning bolt 32 is crimped to the top of the limiting plate 12.

[0031] In this embodiment, the guardrail 20 and the support plate 10 are installed more conveniently by plugging and fitting the guardrail 20 into the sleeve 11 and the limit plate 12 into the embedded pipe 30. The positioning bolt 32 designed in conjunction with the guardrail 20 is screwed into the positioning tube 31, so that the limit plate 12 can be restricted inside the embedded pipe 30, thereby ensuring the stability of the support plate 10 when installed in the embedded pipe 30.

[0032] It should be noted that the embedded pipe 30 is embedded in the bridge deck, the lower end of the embedded pipe 30 is closed, the positioning cylinder 31 and the embedded pipe 30 are coaxially arranged, and the lower end of the positioning cylinder 31 is welded to the bottom of the inner cavity of the embedded pipe 30, and a gap for plugging in the limit plate 12 is formed between the outer wall of the positioning cylinder 31 and the inner wall of the embedded pipe 30, and the aforementioned gap is equal to the thickness of the limit plate 12.

[0033] In addition, the limit plate 12 is constructed to be fan-shaped and coaxially arranged with the embedded pipe 30. The limit plate 12 can rotate around the axis of the embedded pipe 30 inside the aforementioned gap. The axial length of the limit plate 12 is greater than the length of the positioning tube 31, ensuring that when the lower end of the limit plate 12 contacts the bottom of the cavity of the embedded pipe 30, the top surface of the limit plate 12 is higher than the top surface of the positioning tube 31; the support plate 10 and the limit plate 12 are an integrally formed structure, and the support plate 10 is constructed to be an arc coaxially arranged with the limit plate 12, and the inner wall of the support plate 10 is located on the outside of the outer wall of the limit plate 12, so that the top of the limit plate 12 forms a top surface for abutting against the bolt head 33 of the positioning bolt 32.

[0034] When in use, first insert the limit plates 12 of the two support plates 10 into the gap between the embedded pipe 30 and the positioning tube 31, and then screw the positioning bolt 32 into the positioning tube 31 until the bolt head 33 is pressed against the top surface of the two limit plates 12, thereby realizing the installation of the support plate 10 on the embedded pipe 30, and then insert the end of the guardrail 20 into the sleeve 11, and install the support plate 10 on the other side of the guardrail 20, so that the guardrail 20 is finally passed between the sleeves 11 on the two support plates 10.

[0035] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
