Description

Technical Field

[0001] The utility model belongs to the technical field of road traffic engineering construction, and specifically relates to a simple tool for pouring concrete anti-collision guardrails of bridges. Background Art

[0002] Concrete anti-collision guardrail is a type of guardrail that can block colliding vehicles with collision energy less than or equal to the designed protection energy, and plays the role of dissipating energy and correcting the direction of travel.

[0003] At present, the construction site is mainly constructed through on-site cast-in-place method. When pouring concrete, because the top size of the guardrail is small, a hopper is set up and located on the formwork to ensure that the concrete enters the formwork smoothly. However, currently most hoppers are located on the formwork and are not firmly fixed. Personnel are needed to fix them. Cement slurry is easy to leak from the gap between the hopper and the formwork, contaminating the formwork and the bridge deck, affecting the appearance. Utility Model Content

[0004] The utility model aims to solve the above problems and provides a simple tool for pouring concrete anti-collision guardrails for bridges, which can match the lower end of the hopper with the pouring port at the top of the guardrail template and complete the pouring without manual support of the hopper.

[0005] The technical problem to be solved by the utility model is achieved by adopting the following technical scheme: a simple tool for pouring concrete anti-collision guardrails for bridges, comprising a guardrail template, a hopper, a guide pipe and a support rod;

[0006] The hopper is arranged at the upper end of the guide pipe, and the two support rods are arranged oppositely on both sides of the guide pipe;

[0007] The guide pipe matches the pouring port at the top of the guardrail template;

[0008] The support rod is erected above the guardrail template.

[0009] Preferably, the cross section of the support rod is cylindrical. Setting the cross section of the support rod to be cylindrical can reduce the resistance when the hopper is moved.

[0010] Preferably, the two ends of the support rod are provided with rolling wheels, and the rolling wheels are V-shaped wheels. By providing rolling wheels at both ends of the support rod, the resistance when moving the hopper is reduced, and the rolling wheels are V-shaped wheels, which are used to limit the position and prevent the hopper from running off during movement.

[0011] Preferably, the upper end surface of the hopper is provided with a splash-proof edge, which is used to prevent concrete from splashing out from the opposite side of the injection when concrete is injected into the hopper, thereby contaminating the bridge deck.

[0012] Preferably, the splash-proof edge of the utility model comprises a rectangular surface and two right-angled triangular surfaces located on both sides of the rectangular surface, and a right-angled side of the right-angled triangular surface is aligned with one side of the rectangular surface;

[0013] The cross section of the hopper is rectangular, and the rectangular surface and the right-angled triangular surface are arranged at the upper ends of the three edges of the hopper. Since the splash guard includes a rectangular surface and two right-angled triangular surfaces located on both sides of the rectangular surface, when pouring concrete into the hopper, it can be poured from the side opposite to the rectangular surface, which facilitates the insertion of the pouring pipe.

[0014] Preferably, the hopper, the flow guide pipe and the splash-proof edge are all formed by welding steel plates.

[0015] Preferably, the support rod is made of a steel pipe.

[0016] Preferably, the support rod is welded to the flow guide pipe.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows: the simple tool provided by the utility model for pouring concrete anti-collision guardrail of bridges includes a guardrail formwork, a hopper, a guide pipe and a support rod; by setting the hopper at the upper end of the guide pipe, and relatively arranging two support rods on both sides of the guide pipe; since the guide pipe matches the pouring port at the top of the guardrail formwork, the guide pipe can be inserted into the pouring port of the guardrail formwork, solving the problem of the pouring port of the guardrail formwork being too small.

[0018] In addition, by setting up the support rod above the guardrail template, the hopper can be kept stable without manual support, saving manpower. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solutions in the embodiments of the present utility model will be described clearly and completely below in conjunction with the accompanying drawings.

[0027] Example 1

[0028] like Figure 1-Figure 3 As shown, a simple tool for pouring concrete anti-collision guardrail of bridges includes a guardrail template 100, a hopper 1, a guide pipe 2 and a support rod 3.

[0029] The hopper 1 is arranged at the upper end of the flow guide pipe 2, and the two support rods 3 are arranged oppositely at two sides of the flow guide pipe 2. The two support rods 3 are arranged in parallel.

[0030] The guide tube 2 matches the pouring port at the top of the guardrail template 100. That is, the size of the guide tube 2 is consistent with the pouring port at the top of the guardrail template 100.

[0031] The support rod 3 is installed above the guardrail formwork 100 .

[0032] The cross section of the support rod 3 is cylindrical.

[0033] The upper end surface of the hopper 1 is provided with a splash-proof edge 5 .

[0034] The splash guard 5 includes a rectangular surface 51 and two right-angled triangular surfaces 52 located on both sides of the rectangular surface 51, and one right-angled side of the right-angled triangular surface 52 is aligned with one side of the rectangular surface 51. Specifically, the right-angled side of the right-angled triangular surface 52 adjacent to the rectangular surface 51 is consistent in length with the side edge of the rectangular surface 51. The other right-angled side of the right-angled triangular surface 52 is consistent in length with the edge of the hopper.

[0035] The cross section of the hopper 1 is rectangular, and the rectangular surface 51 and the right-angled triangular surface 52 are arranged at the upper ends of the three edges of the hopper 1 .

[0036] The hopper 1, the flow guide pipe 2 and the splash guard 5 are all welded by steel plates.
