Implementation

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all implementations. example. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

Embodiment 1, as shown in Figures 1 to 2, a guardrail for bridge 7 construction includes a fixed base, a column 3, and a beam 4. The fixed base is composed of an upper fixed base 1 and a lower fixed base 6. The vertical column 3 is fixed. It is arranged on the upper fixed base 1. A support column 11 is provided between the upper fixed base 1 and the lower fixed base 6. The two ends of the support column 11 are connected to the upper fixed base 1 and the lower fixed base 6 through the rotating shaft 10 respectively. , a screw 8 is provided between the upper fixed base 1 and the lower fixed base 6, and a rotating base 9 is fixedly provided on the upper surface of the lower fixed base 6. One end of the rotating base 9 and the screw 8 is rotatably connected, so A sliding sleeve 5 is provided between the fixed base 1 and the screw rod 8. The other end of the screw rod 8 is provided with a handle 12 for driving the screw rod 8 to rotate.

Furthermore, reinforcing ribs 2 are provided between the upright column 3 and the upper fixed base 1 .

Furthermore, the upper surface of the upper fixed base 1 is an inclined surface.

Furthermore, the lower surface of the lower fixed seat 6 is an inclined surface.

Furthermore, the upright column 3 is a hollow column.

Furthermore, the cross beam 4 is a hollow beam.

Furthermore, the surface of the beam 4 is red.

When in use, in the initial state, the upper fixed base 1 and the lower fixed base 6 are opened, and they are stuck at the edge of the bridge 7. Turn the handle 12, and the handle 12 rotates to drive the screw 8 to rotate, and the screw 8 rotates to drive the upper fixed base 1 to move upward. , increase the distance between the upper fixed seat 1 and the lower fixed seat 6. Due to the support force of the support column 11, the upper fixed seat 1 and the lower fixed seat 6 are tightened in the box on the side close to the bridge 7, and then the entire guardrail is fixed on The edge of the bridge 7 eliminates the need to open additional holes on the bridge 7 and is easy to install.

The guardrail in the utility model is clamped and arranged at the edge of the bridge through the upper fixing seat and the lower fixing seat, which is convenient for disassembly and assembly without drilling holes to damage the bridge.

Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. In this way, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and equivalent technologies, the present utility model is also intended to include these modifications and variations.
