Description

Safety protective guard suitable for steel shotcrete

Technical Field

The invention relates to a safety protective guard suitable for steel support walking.

Background

With the rapid development of urban construction, the demand of people for transportation is more and more urgent. Subways are widely accepted as convenient and fast ways of urban rapid transit, and meanwhile, the requirement on the comfort level of subway operation is higher and higher. In the construction of a main body structure of a subway station in a coastal region, steel supports are mainly used, in the construction process, workers need to walk on the steel supports in some times, such as building component hoisting, dismantling, pipeline transfer and the like, at present, the walking protection measures are that the workers hang safety belts on cables above the steel supports and then walk by holding the cables, and the safety of the walking mode is not high, especially when the workers walk by holding tools.

Disclosure of Invention

The invention aims to provide a safety protective guard suitable for steel support walking, which can be conveniently and quickly assembled on a steel support, and has high safety and convenient assembly and disassembly.

In order to solve the above problems, the technical solution to be solved by the present invention is:

a safety protective guard suitable for steel support walking comprises a protective guard and a plurality of groups of clamping mechanisms fixedly arranged on a steel support, wherein the protective guard is assembled on the plurality of groups of clamping mechanisms; the clamping mechanism comprises two clamping plates and a plurality of clamps, the clamps comprise two curved bars, the middle parts of the curved bars are hinged together through hinge shafts, the lower ends of the two curved bars are fixed on the two clamping plates respectively, the upper ends of the two curved bars are hinged with screw rods, and the two screw rods are connected through double-end screw sleeves.

The clamping plate is arc-shaped, and a rubber pad is fixedly connected to the clamping plate.

The guardrail includes many risers, through many horizontal pole fixed connection between the riser, is equipped with the inserted bar on the knee lever, and the inserted bar inserts in the riser, and threaded connection has the jackscrew on the riser.

Still include the springboard, the springboard is placed on each group fixture.

And clamping mechanisms are respectively arranged at two ends of each steel support of the construction main body, and the guardrails are assembled on the clamping mechanisms.

The invention has the beneficial effects that: the invention is applied to the construction of station of Yangtze village station and exhibition center station of No. 4 line of Fuzhou subway, thoroughly solves the safety problem of the walking personnel on the steel support and keeps the safe passing of the personnel; and the guard rail is convenient to disassemble and assemble, is suitable for stations erected by steel supports for various subway project enclosure structures, and is worthy of further popularization and application.

Drawings

The invention is further described below with reference to the accompanying drawings:

FIG. 1 is a schematic front view of the present invention,

figure 2 is a side view schematic of the present invention,

figure 3 is a schematic structural view of the present invention in practice,

figure 4 is a schematic structural view of the present invention in practice,

fig. 5 is a schematic structural view of the present invention in practice.

In the figure: the device comprises a cross rod 1, a vertical pipe 2, a double-end threaded sleeve 3, a jackscrew 4, a screw rod 5, a hinge shaft 6, a curved bar 7, a clamping plate 8, a rubber pad 9, a steel support 10 and a springboard 11.

Detailed Description

As shown in fig. 1 to 3, a safety guard rail suitable for steel support walking comprises a guard rail and a plurality of groups of clamping mechanisms fixedly arranged on a steel support 10, wherein the guard rail is assembled on the plurality of groups of clamping mechanisms; the clamping mechanism comprises two clamping plates 8 and a plurality of clamps, each clamp comprises two bent rods 7, the middle parts of the two bent rods are hinged together through a hinge shaft 6, the lower ends of the two bent rods 7 are fixed on the two clamping plates 8 respectively, the upper ends of the two bent rods 7 are hinged with screw rods 5, the rotating directions of the two screw rods 5 are opposite, and the two screw rods 5 are connected through double-end screw sleeves 3.

The using method of the invention comprises the following steps: after the clamping mechanisms are placed on the steel support 10, the two screw rods 5 are driven to move inwards by rotating the double-head threaded sleeves 3, so that the two clamping plates 8 are firmly clamped on the steel support 10, and after all the clamping mechanisms are assembled, the guardrails are assembled on all the clamping mechanisms, and a worker can hold the guardrails to walk on the steel support 10.

The clamping plate 8 is arc-shaped, and a rubber pad 9 is fixedly connected to the clamping plate 8. The rubber pad 9 can play a good anti-slip effect.

The guardrail includes many standpipes 2, through 1 fixed connection of many horizontal poles between the standpipe 2, is equipped with the inserted bar at 7 upper ends of curved bar, and the inserted bar inserts in standpipe 2, and threaded connection has jackscrew 4 on standpipe 2. This kind of structure is convenient to carry out the dismouting to the guardrail, and jackscrew 4 is used for fixing the guardrail.

Still include springboard 11, springboard 11 places on each group's fixture, and the iron wire is tied together springboard 11 and each group's fixture. The springboard 11 facilitates the walking of workers.

As shown in fig. 4 and 5, clamping mechanisms are respectively installed at both ends of each steel support 10 of the construction body, and the guard rail is assembled on each clamping mechanism. The structure can be combined into protective barriers on two sides of the steel support 10, and a good protection effect is achieved.
