[0017] Figure 2 for Figure 1 AA cross-section view. Detailed Implementation

[0018] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] To meet the requirements for the installation and operation of safe and labor-saving cover plates, while reducing interference with existing concrete structures, this utility model provides a reinforcement structure for the groove of a safe and labor-saving cover plate. By reinforcing the groove of the cover plate for lifting holes, it can bear the self-weight of the safe and labor-saving cover plate and the overlying load, thereby improving its safety in use.

[0020] This utility model features a compact structure. Without altering the existing concrete slab and beam structure, to improve the load-bearing capacity of the lifting hole cover groove, a reinforcing structure is installed at the bottom of the cover groove around the lifting hole. This reinforcing structure shares the load with the existing concrete structure, jointly bearing the self-weight of the safe and labor-saving cover and the overlying load, thus meeting the installation and operation requirements of the safe and labor-saving cover. This utility model has a wide range of applications and significant technical and economic advantages.

[0021] See Figure 1 and Figure 2This utility model provides a safe and labor-saving cover plate groove reinforcement structure. The safe and labor-saving cover plate groove reinforcement structure is set around the bottom of the cover plate groove 1 of the lifting hole, and includes a horizontal steel plate 2, a side wall steel plate 3, a vertical bolt 4 and a horizontal bolt 5.

[0022] The horizontal steel plate 2 is located around the bottom of the cover plate groove 1, and its length is the same as that of the cover plate groove 1. The horizontal steel plate 2 is anchored to the concrete floor slab 6 by vertical bolts 4, wherein multiple vertical bolts 4 are spaced apart. The side wall steel plate 3 is fixedly installed on the bottom side of the horizontal steel plate 2 away from the cover plate groove 1, and the horizontal steel plate 2 and the side wall steel plate 3 are welded and fixed at the contact position. The side wall steel plate 3 is located on the side of the structural beam concrete 7, in close contact with the structural beam concrete 7, and is anchored to the structural beam concrete 7 by horizontal bolts 5, wherein multiple horizontal bolts 5 are spaced apart. Therefore, the safe and labor-saving cover plate groove reinforcement structure and the existing concrete structure jointly bear the load, sharing the self-weight of the safe and labor-saving cover plate and the overlying load.

[0023] In this invention, the horizontal steel plate 2 and the side wall steel plate 3 form an L-shaped steel plate, improving the overall rigidity of the L-shaped steel plate. Stiffening ribs 8 are arranged at intervals on the inner side of the L-shaped steel plate to meet structural load-bearing requirements. Specifically, stiffening ribs 8 are provided between the horizontal steel plate 2 and the side wall steel plate 3. Multiple sets of stiffening ribs 8 are arranged at intervals. The stiffening ribs 8 are rectangular, with their tops welded to the bottom surface of the horizontal steel plate 2 and their sides welded to the inner side of the side wall steel plate 3.

[0024] This utility model provides a safe and labor-saving cover plate groove reinforcement structure. Without altering the existing concrete slab and beam structure, a reinforcement structure is installed at the bottom of the cover plate groove around the lifting hole. This reinforcement structure includes a horizontal steel plate, side wall steel plates, stiffening ribs, and anchor bolts. The horizontal steel plate is located at the bottom of the cover plate groove and is anchored to the floor slab by vertical bolts.
