Abstract
Description
Technical Field
[0001] The utility model relates to a safety belt busbar bracket for cap beam shim construction, belonging to the field of high-altitude operation safety protection for bridge shim construction. Background Art
[0002] The Technical Specifications for Safety in Highway Engineering Construction (JTGF90-2015) stipulates that safety guardrails should be installed on the edges of high-altitude work sites and should comply with the following regulations: the guardrails should be able to withstand a variable load of 1000N; if there are people and vehicles passing or working under the guardrails, a dense safety net should be hung to close it, and a footboard with a height of not less than 0.18 meters should be installed at the bottom of the guardrails; the guardrails should consist of two upper and lower horizontal bars, the upper bar should be 1.2 meters high from the ground, and the lower bar should be 0.6 meters high from the ground; when the length of the horizontal bar is greater than 2 meters, a guardrail column should be added.
[0003] According to the current "Classification of Work at Heights" (GB3608), work at height is defined as work where the height difference between the work surface and the reference plane of the falling height exceeds 2 meters. Work at height should comply with the relevant provisions of the current "Technical Specification for Safety of Work at Heights in Construction" (JGJ80): The bottom end of the guardrail pole should be firmly fixed and should comply with the following provisions: When fixed on a concrete floor, ground, roof or wall, the embedded parts should be firmly connected to the pole. The specifications and connections of the guardrail should comply with the following provisions: When steel pipes are used as guardrail rods, the crossbars and railing poles should be made of scaffolding steel pipes, and should be connected and fixed by fasteners, welding, shaped sleeves, etc. When other materials are used as guardrail rods, materials with equivalent strength to the steel pipes should be selected, and they should be connected and fixed by bolts, pins or welding.
[0004] The construction of slabs is very dangerous. Bridges are built to cross obstacles, so the slabs are located at a high position. The construction space is small, there is no place to wear a safety belt, there are no guardrails, and there are many obstacles underfoot, such as slab steel bars, slab formwork, construction tools, cables, wires, blocks and other debris, which can easily cause people to trip and fall. In special circumstances, it is also easy to fall and cause accidents such as dizziness, heat stroke, stepping on air, touching, etc. However, during the high-altitude operation of the cap beam slab construction, there are few safety guardrails for edge operations. The common reasons are: (1) The slab concrete volume is small, the construction cost is low, and the profit is small. The concrete volume of each slab is about 0.06 cubic meters, and the concrete volume of each cap beam slab is about 0.5 cubic meters. (2) The stone support formwork is simple. The stone is about 0.55*0.55*0.2 meters in size. Workers drill holes around the stone and insert steel bars to fix the stone support formwork. After processing the wooden formwork on the ground, they assemble and fix it on the top of the cap beam. The speed is fast. (3) The construction space on the top of the cap beam is small, and it is generally believed that it is impossible to install guardrails. (4) Workers are afraid of trouble and are unwilling to spend time and effort to install guardrails. Workers generally believe that the stone support construction may be completed by the time the guardrails are installed. (5) Because they do not know what safety protection measures to take, even if there is a safety hazard of falling from height, units and departments at all levels are unable to implement rectification and eliminate the hazard, resulting in no effective protection for the lives of construction workers. This also leads to habitual violations of regulations by construction workers. (6) Construction workers have a weak sense of safety.
[0005] A common safety precaution for stone slab construction is to install clamps on the blocks at both ends of the cap beam and tie steel wires as the busbar of the safety belt. However, the block height is only 40 centimeters, which does not meet safety requirements. Construction workers can easily trip and fall on the steel wires, causing safety accidents.

[0027] See also Figure 1-3 The utility model provides a technical solution: a busbar support for a safety belt for construction of a cap beam and a shim stone, comprising a concrete cap beam 1, wherein the concrete cap beam 1 has a construction platform surface 2, and protective rope supports 3 are installed on both sides of the top of the concrete cap beam 1. The total number of the protective rope supports 3 is two, and they are divided into two groups, and a steel wire rope 4 is connected between each group of the protective rope supports 3.
[0028] See Figure 1-3The steel wire rope 4 is divided into an upper steel wire rope 5 and a lower steel wire rope 6. Both ends of the steel wire rope 4 are provided with an integrated steel wire rope clamp 7. The steel wire rope clamp 7 is installed with a shackle 8 through a connecting component. The connecting component is a lock spiral buckle 9. An ear seat 10 is fixed on the protective rope bracket 3. The shackle 8 is buckled on the ear seat 10. The protective rope bracket 3 is L-shaped. The four corners of the top of the concrete cap beam 1 are inlaid with expansion bolts 11. The bottom end surface of the protective rope bracket 3 is provided with a through hole for the expansion bolt 11 to pass through. The protective rope bracket 3 is also fixed with an inclined reinforcing steel 12. The design of the expansion bolt 11 just installs the protective rope bracket 3 at the four corners of the top of the concrete cap beam 1, and then the steel wire rope 4 is installed for protection.
[0029] See Figure 1-5 , the protective rope bracket 3 is also provided with a steel groove 13, and a secondary steel wire rope 14 is passed through the steel groove 13. Both ends of the secondary steel wire rope 14 are provided with an integrated secondary steel wire rope clamp 15. The protective rope bracket 3 is installed with a lap plate 16 overlapped on the top surface of the concrete cap beam 1. Two card slots 17 are provided on the lap plate 16 on one side, and two secondary card plates 24 are fixed on the lap plate 16 on the other side. A protective component is clamped between the card slots 17, and a plurality of mounting plates 18 are fixed on the lap plate 16. The mounting plates 18 are fixed to the protective rope bracket 3 with screws. The protective component is a protective frame 19. The inner side of the protective frame 19 is installed with a protective net 20. A card plate 21 is fixed on one side of the frame 19, and a secondary card slot 22 is provided on the other side of the protective frame 19. Corresponding mounting threaded holes 23 are provided on the card plate 21 and the protective frame 19.

Screws can be inserted into the mounting threaded holes 23 for further fixation. The entire installation is relatively convenient. In terms of transportation, the card plate 21 on the outermost protective frame 19 is inserted into the card slot 17, and the secondary card slot 22 on the outermost protective frame 19 just corresponds to another secondary card plate 24. They are clamped together to complete the overall installation and plug-in, and perform the outermost protection work.
[0030] During the specific work, the protective rope bracket is processed and manufactured, and the concrete cap beam 1 is poured with concrete. When the concrete strength reaches 80%, the expansion bolt 11 is installed, and then the protective rope bracket 3 is installed on the concrete cap beam 1 with the expansion bolt 11. The upper steel wire rope 5 is installed between the top of the protective rope bracket 3, and the lower steel wire rope 6 is installed at the bottom of the upper steel wire rope 5. The two steel wire ropes 4 are used together with the protective rope bracket 3 as edge protection safety ropes.
