Description

Concrete bridge guardrail construction platform device

Technical Field

The utility model relates to a concrete bridge guardrail construction platform device belongs to concrete bridge guardrail construction tool technical field.

Background

In modern construction, in the construction of a plurality of highway bridges and railway bridges, the installation of a cable hanger is one of essential procedures. In site construction, the bridge drilling work has no reserved construction work platform, the bridge drilling on the construction site is difficult, the efficiency is low, and the construction cost is high. At present, a common solution is to use a hanging basket, constructors are in the hanging basket to carry out bridge drilling, but the hanging basket has a safety operation risk, and the hanging basket is inconvenient to disassemble, assemble and move.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a concrete bridge guardrail construction platform device has overcome the not enough of prior art existence, provides a simple structure, safe effectual portable construction platform.

In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides a concrete bridge guardrail construction platform device which characterized in that: including the workstation, counter weight platform and the skeleton of bending into the type of falling U by the reinforcing bar of two parallels, one side welded fastening of workstation and skeleton, the opposite side welded fastening of counter weight platform and skeleton, be equipped with two at least top pulleys on each horizontal reinforcement in the skeleton, be equipped with two at least side pulleys on each vertical reinforcing bar in the skeleton, the device sets up on bridge railing, top pulley and sideslip wheel can block on bridge railing to lateral shifting can be on bridge railing.

Furthermore, the workbench comprises a bottom surface frame, guardrails are arranged around the bottom surface frame, and bearing wood boards are arranged on the bottom surface frame.

Furthermore, the outer side of the counterweight table is connected with the vertical steel bars in the framework through inclined rods.

Further, the diameter of the reinforcing steel bars in the framework is 16 mm.

Compared with the prior art, the utility model following beneficial effect has.

Compared with the common hanging basket, the utility model has higher safety, rapid disassembly and assembly, convenient transportation, simple structure and convenient operation, and well ensures the construction safety; in personnel configuration, 8 people can be configured by 1 original construction, and the number of the people is reduced to 2, so that the manpower is greatly reduced, and the method has certain popularization value, use value and economic value.

In the figure, 1-workbench, 2-counterweight table, 3-framework, 4-top pulley, 5-side pulley, 6-pulley bracket, 7-diagonal rod, 8-guardrail and 9-bridge guardrail.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, the utility model relates to a concrete bridge guardrail construction platform device, including workstation 1, counter weight platform 2 and the skeleton 3 of bending into the type of falling U by the reinforcing bar of two parallels, one side welded fastening of workstation 1 and skeleton 3, counter weight platform 2 and skeleton 3's opposite side welded fastening, be equipped with two top pulleys 4 on each horizontal reinforcement in the skeleton 3, be equipped with two side pulleys 5 on each vertical reinforcement in the skeleton 3, the device sets up on bridge guardrail 9, top pulley 4 and side pulley 5 can block on bridge guardrail 9, and can lateral shifting on bridge guardrail 9.

As an implementation mode, the workbench 1 comprises a bottom surface frame, the periphery of the bottom surface frame is provided with guardrails 8, and the bottom surface frame is provided with bearing wood boards. The outer side of the counterweight table 2 is connected with vertical steel bars in the framework 3 through an inclined rod 7, and the bottom of the counterweight table 2 is also provided with a wood plate. The diameter of the reinforcing steel bar in the framework 3 is 16 mm, and the requirement of bearing can be met. The width of the horizontal steel bar in the framework 3 is set according to the actual thickness of the cement guardrail.

To the working process and principle of the utility model further explain: as shown in FIG. 3, in order to ensure smooth pushing of the device during construction, the left and right side wheels are slightly larger than the thickness of the bridge guardrail. The constructor stands in the workbench 1, and the counterweight table 2 is provided with a counterweight (such as a generator and a cement block) heavier than the weight of the constructor. Constructor disposes 2 safety belts, and 1 disposes on workstation 1's

guardrail

8, and 1 passes through the bolt to be fixed on the hole in the bridge guardrail in addition, and when needs continue to advance, cooperation personnel promote the platform device to advance on the bridge in addition, treat that the platform is stable to be changed the bolt to near bridge guardrail department, continue the operation of this department.

Adopt the utility model discloses a following problem should be noted when the device carries out contact net upper portion construction:

1. the weight used for the counterweight is determined according to the weight of a person entering the operation platform, and is preferably more than 30% of the weight of the operator, so that the stability of the device is ensured, and the sliding of the pulley is flexible.

2. Before the constructors can work safely, 2 safety belts must be tied respectively.

3. After the construction operation of a certain position is finished, the constructor stops the operation and can push the workbench tightly.

4. The safety bolt tied at the guardrail of the bridge needs to adopt a closed loop, and the inserting depth of the bolt is guaranteed when the safety bolt is inserted into the guardrail.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
