For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The following is combined with Figure 1-4 The utility model is further described.

[0022] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a cable-operated platform fixing mechanism for high-altitude skylight construction.

[0023] The specific technical scheme includes a concrete frame beam 1, an H-shaped steel beam 2, a suspension cable fixing component 3 and a vertical fixing component 4. The outer surface of the H-shaped steel beam 2 is equipped with a steel cable protection component 5. The steel cable protection component 5 includes a cushion protection belt 501, a fixing strap 502, a load-bearing ball rod 503 and a limit hook 504. The outer surface of the cushion protection belt 501 is fixedly equipped with two anti-displacement strips 505, one end of the cushion protection belt 501 is fixedly installed with a buckle 506, the interior of the fixing strap 502 is provided with a load-bearing connection hole 507, and the inner side of the cushion protection belt 501 is fixedly installed There is a limit buckle 508, one end of the fixing strap 502 is fixedly connected to one end of the padded protective belt 501, one end of the load-bearing ball rod 503 is fixedly installed on the inner side of the padded protective belt 501, and the anti-displacement strips 505 protrude on both sides, which can prevent the steel wire rope 401 from moving out of the padded protective belt 501 and prevent the steel wire rope 401 from tilting on the H-shaped steel beam 2 to affect the tensioning effect of the steel wire rope 401. The padded protective belt 501 is used to protect the steel wire rope 401, so that it will not be worn and fatigue cracked at the edges and corners of the H-shaped steel beam 2, which helps to increase the strength and service life of the steel wire rope 401.

[0024] The cable fixing assembly 3 is located below the concrete frame beam 1. The cable fixing assembly 3 includes a plastic hose 301, a steel plate 302, an L-shaped rubber pad 303, a joint lock buckle 304 and a steel cable 305. The plastic hose 301 is arranged inside the concrete frame beam 1, the steel cable 305 is installed inside the plastic hose 301, and the steel plate 302 is arranged on one side of the concrete frame beam 1. When installing the cable fixing assembly 3 and the concrete frame beam 1, the measurement and setting out are avoided inside the concrete frame beam 1. The steel bars on the surface are fixed at the same height, the grid lines are divided, and then a 30mm diameter hole is drilled on the main beam at the specified position to penetrate the beam horizontally, with a vertical and horizontal spacing of 1000mm; after the drilling is completed, an L-shaped rubber pad 303 is installed at the bottom of the front cantilever beam and the corresponding position of the hole to prevent the steel cable 305 from being worn and broken at the bottom of the beam, and a 5mm thick plastic hose 301 is put on the outside of the section of the steel cable 305 passing through the hole to pass through the beam to prevent the steel cable 305 from being worn on the hole structure;

[0025] After the steel cable 305 passes through the beam, it is tensioned and anchored. The tensioning order of the steel cable 305 is first in the short axis direction and then in the long axis direction. The detailed points of anchoring and tensioning are as follows: before passing the steel cable 305, make preparations for anchoring. After the steel cable 305 passes through the hole, the anchoring mainly adopts a short steel bar with a length of 10 cm and a diameter of 22 mm. The steel bar 305 is reliably fastened with a lock and then stuck at the hole mouth to bear the force. Each end of the steel cable 305 is tightened, and displacement marks are set on the short steel bar and the steel cable 305 to monitor the displacement of the joint lock buckle 304. The order of passing the steel cable 305 is first in the short axis direction and then in the long axis direction. The rope threading starts from the inner side of the inverted beam structure. At the start, the short-direction steel cable 305 is located below the long-direction steel cable 305, and the two-way steel cables 305 are interwoven into a net.

[0026] The tensioning sequence of the steel cable 305 is first in the direction of the short axis, then in the direction of the long axis, and the steel cable 305 is tensioned symmetrically from the middle to both ends. The steel cable 305 is tensioned using a CDI3t6m hand chain hoist. During tensioning, observe the tension value changes on the instrument panel. When the value reaches a preload of 20kN (the breaking force of the selected steel cable 305 is 190kN, and the preload is 10% of the breaking force, so the integer value of 20kN is taken), the tensioning is stopped. The tensioned steel cable 305 is fixed outside the structure with three joint lock buckles 304. Sufficient length of the steel cable 305 (not less than 10 meters) is reserved at the end of the joint lock buckle 304, and another joint lock buckle 304 is used to fix it. After the steel cable 305 is tightened, two special joint lock buckles 304 are used to fasten it. Ensure that there is no looseness or falling off; the distance between the clips of the steel cable 305 is greater than or equal to 6 to 7 times the diameter of the steel cable 305. The locking buckle 304 needs to be tested in advance, simulating the same fixing method as the on-site conditions, and using a hand winch to apply a tension of 73kN to the test piece, and check the changes in the locking buckle 304 for 24 hours. Before using the SJJA-2 type (rated load 20kN) tensioner, it should be inspected, mainly from its structure and surface, and ensure that the tensioner is intact to prevent the tensioner from malfunctioning during use, causing unnecessary losses and accidents. After the steel cable 305 is put on, it is tensioned again. One end of the steel cable 305 is the fixed end, and the other end is the tensioning end. Then the steel cable 305 is tensioned.

[0027] The degree of tightening of the rope clip is to flatten the steel cable 305 by about 1 / 3 of its original height. Connect another joint lock buckle 304 at least 14d after the last joint lock buckle 304, and make a "safety bend" at the rope end. The height of the safety bend should be controlled at about 150mm. If it is found that the "safety bend" is straightened, unloading measures should be taken immediately.

[0028] The joint lock buckle 304 is fixedly installed on the outside of the steel cable 305, and the vertical fixing component 4 is arranged on the outside of the H-shaped steel beam 2. The vertical fixing component 4 includes a steel wire rope 401, a steel wire U-shaped buckle 402 and a joint lock buckle 403. The joint lock buckle 403 is fixedly installed on the outside of the steel wire rope 401. A vertical unloading rope is set with a steel wire rope 401 with a diameter of 12 mm. The upper part is connected to the H-shaped steel beam 2, and the lower part is connected to the wire rope net. The vertical pulling is used to unload and improve the overall downward winding and flatness of the grid. The unloading rope is arranged at a longitudinal and transverse interval of 4 meters. The longitudinal and transverse steel cables 305 are fastened with steel wire U-shaped buckles 402 at the cross to prevent the steel wire rope 401 from sliding.

[0029] In order for those skilled in the art to fully understand the technical solution, this application makes the following overall summary:

[0030] When in use, before the steel wire rope 401 is sleeved on the H-shaped steel beam 2, the cushion protection belt 501 is first installed on the H-shaped steel beam 2 at the position where the steel wire rope 401 is sleeved. The side of the cushion protection belt 501 equipped with the limit buckle 508 is circled on the outside of the H-shaped steel beam 2 in the direction of the H-shaped steel beam 2, and the fixing strap 502 is passed through the buckle 506, and the fixing strap 502 is pulled downward until the load-bearing connection hole 507 and the load-bearing ball rod 503 are aligned. Then the fixing strap 502 is pressed against the load-bearing ball rod 503 until the load-bearing ball rod 503 is inserted into the load-bearing connection hole 507, providing additional support and stability for the fixing strap 502, ensuring that the fixing strap 502 will not loosen, increasing the stability and safety of the fixing strap 502, and then the limit hook 504 on the fixing strap 502 is hung on the limit buckle 508. The fixing strap 502 is further fixed on the H-shaped steel beam 2, and then the wire rope 401 is passed through the outside of the soft cushion protection belt 501 and located between the two anti-displacement strips 505. After being tightened, the wire rope 401 is bound by the joint lock buckle 403. The anti-displacement strip 505 has protrusions on both sides, which can prevent the wire rope 401 from moving out of the soft cushion protection belt 501, and play a limiting role on the wire rope 401, preventing the wire rope 401 from tilting on the H-shaped steel beam 2 and affecting the tensioning effect of the wire rope 401. The soft cushion protection belt 501 is used to protect the wire rope 401, so that it will not be worn and fatigue cracked at the edges and corners of the H-shaped steel beam 2, helping to increase the strength and service life of the wire rope 401, and the soft cushion protection belt 501 and the H-shaped steel beam 2 can be quickly disassembled and assembled, and the steel cable protection assembly 5 can be reused with the wire rope 401.
