Description

Technical Field

[0001] The utility model relates to a clamp, in particular to a fixing clamp used for a column type traffic warning sign on a bridge. Background Art

[0002] With the implementation of operating specifications, "ground-mounted traffic warning signs" are no longer applicable to highway asphalt pavement maintenance operations, and are replaced by "column-mounted traffic warning signs."

[0003] The existing fixing methods of "column-type traffic warning signs" are: 1. During road construction, they are fixed to the columns with wires, or fixed to the guardrails with clamps; 2. For "bullhorn guardrails" installed on bridge wall guardrails, they are fixed to the "bullhorn guardrails" with wires.

[0004] However, in the renovation and expansion project, the new bridge wall guardrails will no longer be equipped with bullneck guardrails, and the "column-type traffic warning signs" will not be able to be installed and fixed on bridges without bullneck guardrails.

[0005] At present, for bridge wall guardrails that no longer have "bullhorn guardrails", the methods for installing and fixing "column-type traffic warning signs" are: 1. Use iron wire to wrap around the "water drop hole" to fix it; 2. Use "flange" to fix it using expansion screws.

[0006] When encountering a "shorter bridge", the construction method of extending traffic control is usually adopted; but when encountering a bridge with a length of more than 1000m, the fixing of traffic warning signs becomes a problem; even if they are barely placed, their stability is very poor, and special personnel need to be arranged to patrol, which poses a greater safety risk. Summary of the invention

[0010] Furthermore, the inner clip is a special-shaped piece adapted to the inner wall surface of the bridge wall type guardrail.

[0011] Furthermore, weight-reducing holes are distributed on the outer clamp, the inner clamp and the fixed base.

[0012] Furthermore, a limit gear is arranged at the end of the adjusting screw rod passing through the No. 2 threaded hole of the outer clamping piece, and the limit card installed on the outer side wall of the outer clamping piece is inserted into the concave teeth of the limit gear.

[0013] Furthermore, a rubber gasket is fixed at the lower part of the inner side wall of the inner clamping piece, and a fine-tuning gasket is installed on the inner side wall of the outer clamping piece at a height corresponding to the rubber gasket of the inner clamping piece.

[0014] Furthermore, the fine-tuning gasket includes a gasket body, a return spring, and a fine-tuning bolt. The bottom end of the gasket body is mounted on the inner wall of the outer clamp through the return spring, and the fine-tuning bolt passes through the outer clamp and abuts against the gasket body.

[0015] Furthermore, the support cylinder column includes a support cylinder, a sleeve, a connecting shaft and a fastening bolt. A cross-shaped welded sleeve is formed on the outer wall of the support cylinder, the connecting shaft passes through the sleeve, one end of the connecting shaft is fixed to the upper part of the outer wall of the outer clip, and the fastening bolt is arranged on the support cylinder.

[0016] Furthermore, the limiting fastening buckle includes a limiting semi-arc piece, a fastening semi-arc piece, and a fastening bolt. The limiting semi-arc piece is fixed on the outer wall surface of the outer clamp and is located directly below the connecting axis of the supporting column. The fastening bolt is installed on the limiting semi-arc piece, and the front end of the fastening bolt is welded to the fastening semi-arc piece.

[0017] The utility model has the following advantages:
