TECHNICAL FIELD

[0001] The application belongs to the technical field of construction sign fixing support, and particularly relates to a bridge combined guardrail construction sign placing and fixing support. BACKGROUND

[0002] When a road is occupied for construction in a bridge combined guardrail section, a conventional construction process needs to prioritize the arrangement of traffic signboards. In the prior art, there are significant deficiencies in the fixing support for the signboards of the bridge combined guardrail. The traditional method is to use a temporary fixing method of iron wire binding, which not only has the defect of stability, but also is more likely to cause the outer edge of the signboard to exceed the preset position and occupy the emergency lane, forming a safety hazard. In view of this, it is urgent to develop a special fixing device adapted to the structure of the bridge combined guardrail, which realizes the quick installation and accurate positioning of the traffic signboard through the special support integrated with the fixing clamp, so as to ensure that the signboard not only meets the construction warning requirement, but also is strictly controlled within the safety boundary range.

[0006] In one scheme, the concrete U-shaped buckle is fixedly connected with the signboard support pipe through a transverse pipe, and the transverse pipe is welded with the concrete U-shaped buckle and the signboard support pipe respectively.

[0007] In one scheme, the concrete U-shaped buckle comprises a U-shaped main body and a locking bolt connected with the U-shaped main body, and a T-shaped nut is connected with the locking bolt.

[0008] In one scheme, the inclined pull rod is welded with the U-shaped main body.

[0009] In one design, two locking bolts are symmetrically arranged on the U-shaped body, with the two locking bolts located on both sides of the sign support tube.

[0010] Positive effects:

[0011] (1) The double fixing method of “concrete U-shaped buckle + movable fastener” is adopted to directly fix the bracket to the bridge combination guardrail, which improves the safety and stability of the entire bracket and reduces the encroachment of construction signs on the road surface.

[0012] (2) The movable fasteners are adjustable, which can ensure the safety, stability and flexibility of the entire support and improve construction efficiency. Attached Figure Description

[0016] The specific implementation of this application is further described below with reference to the accompanying drawings. This application is not limited to the description of the following embodiments.

[0017] Example 1

[0018] like Figure 1 and 2 As shown, a bridge composite guardrail construction sign placement and fixing bracket includes a sign support tube 1, a concrete U-shaped buckle 2 fixedly connected to the sign support tube 1, a diagonal tie rod 3 connected to the concrete U-shaped buckle 2, and a movable fastener 4 connected to the diagonal tie rod 3. The upper part of the sign support tube 1 is provided with multiple locking bolts 8 for fixing the sign, and T-nuts are connected to the locking bolts 8. The concrete U-shaped buckle 2 is located at the lower part of the sign support tube 1. The movable fastener 4 includes a spring clip 41. One end of the diagonal tie rod 3 is fixedly connected to the concrete U-shaped buckle 2 via a hinge 5, and the other end of the diagonal tie rod 3 is welded to the movable fastener 4.
