DETAILED DESCRIPTION

[0023] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application.

[0024] The present embodiment includes several U-shaped steel plates 1, which are clamped on the support beams with the openings downward. If the inner width of the U-shaped steel plate 1 is equal to the width of the support beam, the U-shaped steel plate 1 is clamped on the support beam. In order to make the U-shaped steel plate 1 clamped on the support beam more tightly, the U-shaped steel plate 1 can be slightly wider at the top and narrower at the bottom, i.e. the longitudinal section of the U-shaped steel plate 1 is trapezoidal, and the inner width of the lower part is 2-5 cm smaller than that of the upper part. In this way, the side plates of the U-shaped steel plate 1 have a certain clamping force on the support beam, and the U-shaped steel plate 1 can be clamped on the support beam more firmly. Since the U-shaped steel plate 1 is the basis for installing the guardrail later, in order to ensure the firmness, the length of the U-shaped steel plate 1 is preferably 30-60 cm, and the length here refers to the length along the direction of the support beam. The height of the side plate of the U-shaped steel plate 1 is not less than 50 cm.

[0025] The vertical fixing pipes 2 are symmetrically full-welded on the left and right outer sides of the U-shaped steel plate 1. The upper end of the fixing pipe 2 is open, and the lower end is closed. The fixing pipe 2 is used for inserting the vertical rod 12 of the guardrail installed later. Since the vertical rod 12 of the guardrail can be a circular pipe or a rectangular pipe, the fixing pipe 2 can also be a circular pipe or a square pipe. The size of the fixing pipe 2 is consistent with the size of the vertical rod 12 of the guardrail, so as to ensure that the vertical rod 12 can be inserted into the fixing pipe 2. In order to ensure the stability of the guardrail, the height of the fixing pipe 2 is preferably not less than 50 cm.

[0026] Since the U-shaped steel plate 1 will be gradually deformed after repeated use for many times, the two sides will be opened outward, cannot be tightly clamped on the supporting beam, and the installed guardrail will be inclined and poor in stability, the application is improved in that the hooks 3 are welded on the bottom of the left and right outer sides of the U-shaped steel plate 1, the steel wire ropes 4 are fixed on the hooks 3, and the steel wire ropes 4 on the two sides are fixed on the one-way bearing 5. The one-way bearing 5 is located on the bottom surface of the supporting beam, two annular grooves 6 are arranged on the outer periphery of the outer ring of the one-way bearing 5, the steel wire ropes 4 on the two hooks 3 are wound to the bottom surface of the supporting beam and fixed in the two annular grooves 6, and when the outer ring of the one-way bearing 5 rotates, the steel wire ropes 4 on the two sides can be wound on the two annular grooves 6. A poking column 7 is fixed on the outer ring of the one-way bearing 5, and the poking column 7 is used for rotating the outer ring of the one-way bearing 5. Two notches 8 are symmetrically arranged on the inner wall of the inner ring of the one-way bearing 5. A fixing block 9 is further included, the fixing block 9 is in a T shape as a whole and is divided into an upper part and a lower part, the length of the upper part of the fixing block 9 is greater than the length of the lower part of the fixing block 9, the lower part of the fixing block 9 can be inserted into the two notches 8 of the inner ring of the one-way bearing 5, the size of the lower part of the fixing block 9 is consistent with the size of the notches 8, the lower part of the fixing block 9 is used for preventing the rotation of the inner ring of the one-way bearing 5, the upper part of the fixing block 9 is pressed on the surface of the inner ring of the one-way bearing 5, and the rotation of the inner ring is further prevented. When the lower part of the fixing block 9 is inserted into the notches 8 and the inner ring of the one-way bearing 5 is pressed towards the bottom surface of the supporting beam, the poking column 7 can be grabbed to rotate the outer ring of the one-way bearing 5 at this time, the inner ring cannot rotate due to the blocking of the fixing block 9, only the outer ring can rotate, the rotation of the outer ring of the one-way bearing 5 can further wind and tighten the steel wire ropes 4 on the two sides, and the steel wire ropes 4 on the two sides pull the side plates of the U-shaped steel plate 1 to tightly adhere to the left and right side surfaces of the supporting beam, the deformation and opening of the U-shaped steel plate 1 are solved, and the stability of the U-shaped steel plate 1 is ensured without the need of designing other structures for reinforcement.

[0027] Preferably, the L-shaped bracket 10 is fixed on one side surface of the U-shaped steel plate 1, the L-shaped bracket 10 is used for placing the downpipe, the horizontal arc-shaped pipe bracket 11 is fixed on the other side surface of the U-shaped steel plate 1, and the power cable can be placed in the arc-shaped pipe bracket 11.

[0028] When installing, after the earthwork under the support beam is opened to a certain depth, and there is installation and operation space of the one-way bearing 5, at this time, press the U-shaped steel plate 1 downward to tightly clamp on the support beam, clamp a U-shaped steel plate 1 on the support beam every certain distance, after all the U-shaped steel plates 1 are installed, place the one-way bearing 5 on the bottom surface of the support beam opposite to the U-shaped steel plate 1, hang the steel wire rope 4 on the two annular grooves 6 of the one-way bearing 5 on the hooks 3 on both sides respectively, fix the steel wire rope 4 and the hooks 3, at this time, the steel wire rope 4 is in a relaxed state, then the worker inserts the fixing block 9 under the support beam into the gap 8 of the one-way bearing 5, so that the inner ring of the one-way bearing 5 cannot rotate, at the same time, rotate the outer ring of the one-way bearing 5 by holding the push rod 7, the outer ring of the one-way bearing 5 rotates to gradually wind the steel wire rope 4, the steel wire ropes 4 on both sides are wound in the annular grooves 6 of the outer ring of the one-way bearing 5 respectively, the steel wire rope 4 is gradually tightened, until the two sides of the U-shaped steel plate 1 tightly clamp the side surface of the support beam, at this time, take out the fixing block 9, the one-way bearing 5 is attached to the bottom surface of the support beam, and each U-shaped steel plate 1 is provided with a one-way bearing 5 below, after all the U-shaped steel plates 1 are installed, insert the vertical rods 12 of the guardrail into the fixed pipes 2 on both sides, and then fix the horizontal rods of the guardrail on the vertical rods 12 through the buckles, to form the guardrail, and the installation is completed. When disassembling, cut the steel wire ropes 4 on both sides, take down the U-shaped steel plate 1 and the one-way bearing 5, the U-shaped steel plate 1 and the one-way bearing 5 can be used repeatedly, and when used again, a new steel wire rope 4 can be fixed on the one-way bearing 5. During construction, the dewatering pipe can be placed on the L-shaped bracket 10 of the U-shaped steel plate 1, and the power cable can be placed in the arc-shaped supporting pipe 11, so that the placement of the dewatering pipe and the power cable is solved.
