Hoop installation safety platform

Abstract

The utility model relates to a hoop installation safety platform. The hoop installation safety platform comprises an annular supporting platform and guardrails vertically arranged on the periphery of the annular supporting platform. The shape of the opening is matched with that of the installed hoop, and the area of the opening is larger than the sectional area of the installed hoop. The annular supporting platform is composed of a steel plate and angle steel welded to the bottom face of the steel plate, and the guardrails are formed by welding channel steel serving as vertical rods and angle steel serving as transverse rods. The lower ends of the vertical rods are fixedly welded to the annular supporting platform, and skirting boards are arranged on the guardrails. The hoop installation safety platform further comprises a rubber buffer strip or a rubber buffer ring surrounding the edge of the opening. When the hoop is used for installing the safety platform, the hoop installation efficiency can be greatly improved, and the installation risk is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge construction tools, in particular to a clamp installation safety platform. Background Art

[0002] The clamp method is a conventional construction method for cap beam construction. The double clamp method is to set a position below the top of the pier column, such as 120cm below the top of the pier column, and set two stacked steel clamps. Bolt the clamps tightly to the pier column, and set a sand box on each of the two lifting ears of the clamp located above to fine-tune the elevation and facilitate the removal of the cap beam bottom plate. At present, for the installation of the clamp, workers use the ladder or bracket used in the construction of the pier column to go up and down, and use a truck crane to lift the clamp to the preset elevation position and then tighten it. Since the clamp can only be hoisted after the concrete strength of the pier column reaches the set strength, this method leads to long-term occupation of the ladder or bracket, or repeated disassembly and assembly of the ladder or bracket. The ladder or bracket is a certain distance away from the pier column, and the installation process is not friendly to workers. Utility Model Content

[0022] A clamp mounting safety platform according to an embodiment of the utility model is described below with reference to the accompanying drawings.

[0023] See also Figure 1 and Figure 2 According to an embodiment of the utility model, a clamp installation safety platform includes an annular support platform 1 and a guardrail 2 erected around the annular support platform 1. An opening 3 is formed in the middle of the annular support platform 1, and the opening 3 matches the shape of the clamp after installation and has an area larger than the cross-sectional area of ​​the clamp after installation. Preferably, the area of ​​the opening 3 is slightly larger than the cross-sectional area of ​​the clamp after installation. After the clamp is pre-assembled, the clamp can be hoisted onto the annular support platform 1, and the clamp can be placed at 90° to intersect with the opening 3. Then, the clamp installation safety platform is hoisted and inserted into the pier column using a wire rope and a car crane, and the positioning is assisted manually. After accurate positioning, the clamp is tightened. After the clamp is installed in place, the platform can be rotated to align the opening 3 with the shape of the clamp, and the platform can be lifted away. Using the clamp installation safety platform can greatly improve the efficiency of clamp installation and reduce installation risks.

[0024] In this embodiment, the annular support platform 1 is composed of an octagonal steel plate and an angle steel welded to the bottom of the steel plate, the guardrail 2 is welded with channel steel as the vertical pole and angle steel as the horizontal pole, and the lower end of the vertical pole is welded and fixed to the annular support platform 1. The guardrail 2 is provided with a skirting board 4 to prevent tools from slipping off the edges of the clamp mounting safety platform.

[0025] The clamp installation safety platform also includes a rubber buffer strip surrounding the edge of the opening 3. Specifically, the rubber buffer strip can be a rubber strip made of rubber with a U-shaped cross section, the opening 3 of the rubber strip faces the edge of the opening 3, and is fixed to the edge of the opening 3 by adhesive. The rubber buffer strip prevents the pier from directly contacting the edge of the opening 3, and is elastic, which can reduce or avoid the pier from being scratched when the clamp installation safety platform is inserted into the pier or lifted off the pier.

[0026] In another embodiment, a rubber buffer ring may be used to replace the rubber buffer strip. Specifically, the rubber buffer ring may be a rubber ring made of rubber with a U-shaped cross section, fixed to the edge of the opening 3 by adhesive, and the rubber buffer ring prevents the pier from directly contacting the edge of the opening 3, and is elastic, which can reduce or avoid the pier being scratched by the clamp installation safety platform during the process of inserting into the pier or lifting off the pier.

[0027] See now Figure 3 and Figure 4 In another embodiment, the clamp installation safety platform further includes a locking device, which includes a plurality of struts 5 hinged to the outer edge of the annular support platform 1, and each of the struts 5 is connected to a first rope 6 and a second rope 7. The free end of the first rope 6 passes through the through hole 8 formed by the annular support platform 1, and the first rope 6 can pull the free end of the strut 5 toward the pier to cause the strut 5 to be against the peripheral wall of the pier in an inclined state. Preferably, the number of the struts 5 is preferably greater than or equal to three, and is distributed in an annular array. After the clamp installation safety platform is hoisted into place, the strut 5 is against the peripheral wall of the pier in an inclined state, which can make the clamp installation safety platform more stable, and can provide temporary support force when the wire rope accidentally falls off, thereby improving safety. In order to ensure that the strut 5 can continue to be against the peripheral wall of the pier in an inclined state, a rope buckle can be used to maintain the portion between the binding end of the first rope 6 and the through hole 8 in a tensioned state and lock the length.

[0028] The free end of the strut 5 can be pulled toward the guardrail 2 by the second rope 7 . After the strut 5 is close to the guardrail 2 , the second rope 7 can be used to bind the strut 5 to the guardrail 2 .

[0029] In order to prevent the support rods 5 from scratching the pier column, the free end of each support rod 5 is sleeved with a rubber sleeve.
