Description

Technical Field

[0001] This utility model relates to the field of building component technology, and in particular to a movable steel cover plate for equipment hoisting holes. Background Technology

[0002] In practical use, industrial buildings typically have equipment hoisting holes on their roofs for equipment hoisting, installation, and maintenance. These holes are crucial for transporting large equipment, and their usage frequency is uncertain. When not in use, covers are installed at these holes for safety and waterproofing. Traditional roof hoisting hole covers have significant drawbacks: fixed steel plates require welding or bolting, and disassembling the cover when the hoisting hole needs to be accessed reduces efficiency due to cutting welds or removing bolts; the large weight of the single steel cover makes opening difficult; and multiple assembled covers have waterproofing defects at the joints. Utility Model Content

[0003] The purpose of this utility model is to provide a movable steel cover plate for equipment hoisting holes, which is convenient for disassembly and installation, improves efficiency, and has good waterproof performance.

[0004] The technical solution of this utility model is: a movable steel cover plate for equipment hoisting holes, comprising multiple steel plates sequentially spliced ​​in the Y direction and a waterproof cover plate covering the joint between two adjacent steel plates. Each steel plate includes a top plate, and the upper surfaces of both ends of the top plate in the X direction are provided with steel grabs for hoisting. The lower surfaces of both ends of the top plate in the X direction form support surfaces for placement on the back edge of the equipment hoisting hole. A reinforcing plate is provided on the lower surface of the top plate, and the reinforcing plate is located between the two support surfaces. The X direction and the Y direction are perpendicular to each other on the same top projection plane.

[0005] Preferably, the reinforcing plates enclose a rectangle.

[0006] Preferably, the reinforcing plate and the steel gripper are on the same vertical line.

[0007] Preferably, the steel gripper is U-shaped, with its opening facing the top plate.

[0008] Preferably, both ends of the top plate in the Y direction are provided with water-blocking reverse edges, which are connected to the upper surface of the top plate, and the water-blocking reverse edges are of the same length as the top plate in the X direction.

[0009] Preferably, the waterproof cover is made of channel steel, and the two adjacent water-blocking reverse edges at the joint of the top plate are placed inside the waterproof cover.

[0010] Preferably, the top plate is a patterned plate, and the reinforcing plate is Q235B.

[0011] Compared with related technologies, the beneficial effects of this utility model are as follows:

[0012] I. This utility model provides a waterproof cover at the joint of multiple spliced ​​steel plates, which can effectively waterproof the joint and improve its waterproof performance.

[0013] Second, this utility model has steel grabs on the top plate, and the two ends of the top plate form a support surface that can be placed directly on the back edge of the equipment hoisting hole. No welding or bolt fixing is required. During disassembly, the cover plate can be quickly removed directly through the steel grabs, making installation and disassembly more convenient and efficient.

[0014] Third, the steel plate of this utility model can be prefabricated in the factory, and only multiple pieces need to be spliced ​​with the waterproof cover plate on site, which reduces the amount of on-site work and improves assembly efficiency.

[0015] Fourth, the lower surface of the top plate is equipped with a reinforcing plate, which can increase the rigidity and load-bearing capacity of the top plate and meet the requirements of large-diameter equipment hoisting holes. Attached Figure Description

[0020] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0021] like Figure 1 As shown, the movable steel cover plate for equipment hoisting holes provided in this embodiment includes a plurality of steel plates 1 spliced ​​sequentially in the Y direction and a waterproof cover plate 3 covering the joint between two adjacent steel plates 1.

[0022] like Figure 2 , Figure 3As shown, the steel plate 1 includes a top plate 11, a reinforcing plate 12, a water-blocking reverse edge 13, and steel grabs 14. The top plate 11 has a length direction X and a width direction Y. Steel grabs 14 for lifting are provided on the upper surfaces of both ends of the top plate 11 in the X direction. The steel grabs 14 are made of 10mm diameter round steel, are U-shaped, and their openings face the top plate 11. The top plate 11 is made of 6mm thick checkered plate.

[0023] The lower surfaces at both ends of the top plate 11 in the X direction form support surfaces for placement on the equipment hoisting hole back edge 2. In use, the support surfaces are placed directly on the equipment hoisting hole back edge 2, and the length of the support surfaces is longer than the thickness of the equipment hoisting hole back edge 2, thus achieving stable placement.

[0024] A reinforcing plate 12 is provided on the lower surface of the top plate 11, and the reinforcing plate 12 is located between the two supporting surfaces. The reinforcing plate 12 encloses a rectangle (e.g., Figure 1 (As shown). The reinforcing plate 12 is used to increase the rigidity and load-bearing capacity of the top plate 11. The top plate 11 and the reinforcing plate 12 are intermittently welded. The thickness of the reinforcing plate 12 is 6mm, and the material is Q235B grade steel. The reinforcing plate 12 and the steel grab 14 are on the same vertical line (as shown). Figure 2 (As shown).

[0025] Both ends of the top plate 11 in the Y direction are provided with water-blocking reverse edges 13. The water-blocking reverse edges 13 are connected to the upper surface of the top plate 11, and the water-blocking reverse edges 13 are the same length as the top plate 11 in the X direction.

[0026] The waterproof cover plate 3 is a channel steel made of Q235B grade steel. Two adjacent water-retaining reverse edges 13 at the joint of the top plate 11 are placed inside the waterproof cover plate 3. The water-retaining reverse edges 13 are welded to the top plate 11 using continuous fillet welds. The thickness of the water-retaining reverse edges 13 is 6mm. The material of the water-retaining reverse edges 13 is Q235B grade steel.

[0027] This utility model provides a movable steel cover plate structure for equipment hoisting holes. The steel cover plate, composed of a top plate, stiffening plate, water-blocking reverse edge, and steel grab, can be directly welded and manufactured in the factory, making it simple to manufacture. Multiple steel cover plates can be supported on the concrete reverse edge around the hoisting opening, making them easy to install and disassemble. The joint waterproof cover plate is inverted at the joint of the steel cover plate, which can effectively solve the problem of joint waterproofing.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
