The cast-in-place side guardrails are made of concrete, and the concrete foundation is firmly connected, which can achieve a higher protection level. Demolition is usually destructive and cannot be reused. The prefabricated side guardrail uses concrete prefabricated formwork, which is reusable and low-carbon and environmentally friendly. However, during the installation and disassembly of the outer formwork of the side guardrail, it is laborious for the construction personnel to work at heights, and the construction period of the guardrail is long. During the construction period of the guardrail, large machinery has been used The formwork hoisting by crane is not only expensive, but also large-scale mechanical cranes occupy a large area, which is not conducive to the simultaneous construction of other parts of the bridge. Therefore need a kind of small-sized device that can be used in bridge edge guardrail formwork construction and can replace large mechanical crane.

Detailed ways

As shown in Figure 1, the utility model comprises a workbench 4, a vehicle frame, a vehicle frame slide rail 5 arranged on the bridge, and a template hoisting unit and a workbench suspension unit arranged on the vehicle frame, and the vehicle frame includes a bottom plate 1. The cross bar 3 arranged above the base plate 1 and the frame diagonal bar for fixedly connecting the base plate 1 and the cross bar 3, the lower end of the base plate 1 is provided with a car frame slidingly connected with the frame slide rail 5 Frame pulley 6, the template hoisting unit includes a sprocket 8-2 and a sprocket handle 8-1 for rotating the sprocket 8-2, the sprocket 8-2 is wound with a lifting chain 8-3, One end of the suspension chain 8-3 is fixedly connected to the sprocket 8-2, the other end of the suspension chain 8-3 is fixedly connected with a suspension hook 8-4, and the bottom plate 1 is provided with a suspension chain support rod 9 One end of the chain support rod 9 is fixed on the base plate 1, the other end of the chain support rod 9 is provided with a chain pulley 9-1, and the workbench suspension unit includes two The first workbench lifting rod at the end and the second workbench lifting rod, the first workbench lifting rod is provided with a first sling 10-2 for connecting one end of the workbench 4, and the second workbench lifting rod is A second sling 11-2 for connecting the other end of the workbench 4 is provided.

It should be noted that there are two frame slide rails 5 on the bridge, and four frame pulleys 6 are arranged at the lower end of the bottom plate 1. The four frame pulleys 6 are arranged on the four corners of the bottom plate 1 respectively. At the lower end, the frame pulley 6 is slidingly connected with the frame slide rail 5, so the base plate 1 can slide on the bridge, thereby driving the frame to slide on the bridge, improving the convenience of bridge construction.

It should be noted that the suspension chain support rod 9, the first workbench lifting rod and the second workbench lifting rod are all located on the same side of the bridge.

During actual use, the suspension chain 8-3 is a chain or a steel wire rope, which can be bent arbitrarily. In the absence of the suspension chain support bar 9, the suspension chain 8-3 extending out of the bridge side guardrail is in the natural state with the suspension chain 8-3 The contact point with the bridge side guardrail is perpendicular to the ground, and the hoisted bridge side guardrail template is easy to collide with the bridge side guardrail, which affects the construction effect. Therefore on the base plate 1, the hanging chain support bar 9 extending out from the bridge side guardrail is set, and the hanging chain pulley 9-1 on the hanging chain supporting bar 9 provides a support point for the hanging chain 8-3, so that the hanging chain 8-3 is in a natural position. In this state, the position point of the suspension chain pulley 9-1 is perpendicular to the ground, thereby changing the vertical position of the suspension chain 8-3, thereby changing the distance between the suspension hook 8-4 connected on the suspension chain 8-3 and the bridge side guardrail. distance, the effect is good. One end of the chain support rod 9 is fixedly connected to the bottom plate 1, and the middle section of the chain support rod 9 is connected to the cross bar 3. The cross bar 3 provides a support point for the chain support rod 9 to improve the stability of the chain support rod 9. sex.
