Description

Technical Field

[0001] The utility model relates to the technical field of blocking holes in floors, in particular to a cover plate device for reserved equipment installation holes on the floors of steel structure workshops. Background Art

[0002] During the construction of the single crystal furnace steel structure plant, steel beams are usually used, and a floor will be set up in the middle of the plant to install the single crystal furnace. The floor is paved with an I-shaped steel beam as the foundation, and then concrete is poured; but due to the large size of the single crystal furnace, the height and width of the single crystal furnace are large, the vertical distance between the floor and the ground needs to be controlled at 6.3 meters, and the size of the equipment hole reserved on the floor is 3.8m×3.2m, so that the single crystal furnace foundation can be passed through the reserved equipment hole and installed. Subsequently, the floor needs to be poured with concrete, and a large number of workers are interspersed in the work. If the hole protection is not in place, falling from a height is very likely to occur, causing safety accidents. The hole plugging methods commonly used now include: steel plate covering, bolting safety nets, pulling warning tapes, etc., but because a single crystal furnace plant is usually arranged in parallel with multiple single crystal furnaces, the number of reserved equipment holes on the floor is large, and the hole size is large, involving more interlaced operations, and people walking frequently at the edge of the hole. Even if the installation net is bolted and the warning tape is pulled, there are still great safety hazards. If steel plates are used for covering, the required steel plate area and weight are large, which makes transportation and installation inconvenient. In order to facilitate disassembly and assembly, CN218205862U "A kind of The article "Easily detachable and expandable floor hole cover" provides an easily detachable and expandable floor hole cover. The expansion of the cover uses a telescopic frame and a joint bearing. During the construction of a single crystal furnace plant, there is a lot of dust, and the telescopic frame and the joint bearing are easily covered by dust. In addition, since the cover is a covering cover, when concrete is used for subsequent sealing, it will also cause concrete pollution to other hole covers near the hole, thereby losing its mobility. Moreover, components such as the telescopic frame are very likely to be deformed due to various collisions or operations during use, affecting the normal deployment of the entire cover.

Both ends are connected to the floor 1; the hanging piece 3 includes a clamping block 31, a hanging rod 32 and an annular hanging ear 33, the top of the clamping block 31 is provided with a through groove 311 for the lower flange of the I-shaped steel beam 12 to pass through, the through groove 311 includes a horizontal through groove 3111 and a vertical through groove 3112, and the horizontal through groove 3111 and the vertical through groove 3112 are in a "⊥" shape; the hanging rod 32 is arranged below the clamping block 31, and the lower end of the hanging rod 32 is welded with an annular hanging ear 33, and the end of the transverse steel pipe 21 passes through the annular hanging ear 33 to be connected to the hanging piece 3.

[0025] like Figure 1 As shown, the steel structure plant of the single crystal furnace made of steel beams is provided with I-shaped steel beams 12 on both sides below the reserved equipment installation holes 11 on the floor, so as to facilitate the subsequent installation of the hanging parts 3, so that the hanging parts 3 are connected to the floor 1; when the cover plate device of the reserved equipment installation holes 11 on the floor is used, Figure 2-Figure 9As shown, align the through slot 311 of the clamping block 31 with the lower flange of the I-shaped steel beam 12 located around the reserved equipment installation hole 11 on the floor, and clamp the clamping block 31 on the I-shaped steel beam through the "⊥"-shaped through slot 311, so that the hanging piece 3 is connected to the I-shaped steel beam 12 set below the floor 1; the entire cover base 2 is hoisted on the lower flange of the I-shaped steel beam 12 through the transverse steel pipe 21 set on the annular lifting ear 33. At this time, the cover base 2 is located directly below the reserved equipment installation hole 11 on the floor. The size of the cover plate body 4 is adapted to the reserved equipment installation hole 11 on the floor. At this time, the cover plate body 4 laid on the cover plate base 2 can be completely embedded in the reserved equipment installation hole 11 on the floor, so as to realize the closure of the reserved equipment installation hole 11 on the floor, and after the reserved equipment installation hole 11 on the floor is closed, the periphery is flat and has no protrusions; the horizontal steel pipe 21 and the longitudinal steel pipe 22 of the above-mentioned cover plate base 2 can be connected by welding, but in order to make the cover plate base 2 suitable for the reserved equipment installation holes 11 of different sizes, such as Fig. 9 As shown, the existing buckle 23 can be used to realize the detachable connection between the horizontal steel pipe 21 and the longitudinal steel pipe 22, so as to achieve the connection of the horizontal steel pipe 21 and the longitudinal steel pipe 22 of different lengths according to the needs, and it is convenient to reuse the cover base 2 after the subsequent disassembly; in order to ensure the stability of the cover base 2, the horizontal steel pipe 21 and the vertical steel pipe 21 can be set in multiples, and set into a mesh structure. The cover device of the floor reserved equipment installation hole is used, and the cover base 2 is set directly below the floor reserved equipment installation hole 11 through the hanging piece 3, so that the cover body 4 can be embedded in the floor reserved equipment installation hole 11, and after the floor reserved equipment installation hole 11 is closed, the surrounding area is flat and has no protrusions, which ensures the safety of construction personnel when cross-operating, and can effectively prevent construction personnel from falling due to the protrusion, so that the transportation operation tool can be normally moved on the floor 1, which is convenient for construction; at the same time, the cover device of the floor reserved equipment installation hole has a simple structure and is easy to disassemble and assemble. The hanging piece 3 is installed on the I-shaped After the lower flange of the steel beam is installed, the cover base 2 can be set just below the reserved equipment installation hole 11 on the floor, and the cover body 4 can be laid and embedded in the reserved equipment installation hole 11 on the floor to close the reserved equipment installation hole 11 on the floor. The installation speed is fast and the covering effect is good. The cover body 4 is located at the top of the cover device of the entire reserved equipment installation hole on the floor. Therefore, the hanger 3 and the cover base 2 will not be affected by the dust and concrete constructed above the floor 1, which effectively avoids the situation where the connection cannot be used normally due to dust or concrete, thereby ensuring the normal use of the cover device of the reserved equipment installation hole on the floor.

[0026] To ensure the connection stability between the clamping block 31 and the lower flange of the I-beam under the floor 1, Figure 5 , Figure 8As shown, a clamping mechanism 34 is also provided on the clamping block 31, and the clamping mechanism 34 includes a nut 342 and a screw rod 341. The screw rod 341 is penetrated and arranged on the clamping block 31 in a direction parallel to the horizontal through groove 3111, and both ends of the screw rod 341 extending out of the clamping block 31 are threadedly connected with nuts 342; by tightening the nut 342, the distance between the two sides of the clamping block 31 penetrated by the screw rod 341 is shortened, thereby achieving the purpose of shrinking the horizontal through groove 3111, so that the lower flange of the steel beam located in the horizontal through groove 3111 is clamped in the through groove 311, thereby fixing the relative position of the clamping block 31 and the floor 1, and ensuring the stability of the cover device of the equipment installation holes reserved in the entire floor after installation.

[0027] In order to better clamp the lower flange of the steel beam located in the through groove 311, Figure 6 As shown, two oppositely arranged wedge-shaped surfaces 312 are provided on the top of the clamping block 31, and the wedge-shaped surfaces 312 face the vertical through groove, and the bottom of the wedge-shaped surfaces 312 abuts against the horizontal through groove 3111; by providing the wedge-shaped surfaces 312 on the top of the clamping block 31, when the clamping block 31 is used to connect with the lower flange of the I-shaped steel beam 12, the bottom of the wedge-shaped surfaces 312 can abut against the horizontal plate of the I-shaped steel beam, so as to clamp the lower flange of the steel beam located at the junction of the horizontal through groove 3111 and the vertical through groove 3112, and then when the above-mentioned clamping mechanism 34 is used for contraction clamping, the bottom of the wedge-shaped surfaces 312 is tightened toward the lower flange of the I-shaped steel beam 12 and abuts against it, so as to strengthen the clamping force on the lower flange of the steel beam and ensure the installation stability.

[0028] Due to the different thickness of the floor 1, the thickness of the cover body 4 to be laid is different. In order to make the top surface of the laid cover body 4 always level with the top surface of the floor 1, the hanger 32 is a hydraulic telescopic hanger, which is used to control the height of the cover base 2, and then to control the height of the laid cover body 4, so that the top surface of the cover body 4 is level with the floor 1, ensuring the safety of the construction workers when they are working on the floor 1; at the same time, the hydraulic telescopic hanger adopted can meet the needs of the cover body 4 that bears greater gravity; in addition, by controlling the height of the cover base 2 and the cover body 4, the entire cover device can also be used as a lifting construction platform. Figure 4 , Figure 5 It can also be represented as a schematic structural diagram after the cover plate body 4 moves downward along with the suspension rod 32.

[0029] In order to ensure the balance of the hanging member 3 and the stability of the cover base 2, two symmetrically arranged annular hanging ears 33 are welded to the lower end of the hanging rod 32; each annular hanging ear 33 is provided with a transverse steel pipe 21; Figure 7As shown, two symmetrically arranged annular ears 33 are welded to the lower end of the suspension rod 32. The symmetrically arranged annular ears 33 increase the number of transverse steel pipes 21 that can be installed on the same suspension member 3, and ensure the balance of the suspension rod 32. The cover base 2 will not be tilted due to deformation due to uneven force, thereby ensuring the stability of the cover body 4 after being laid on the cover base 2.

[0030] To facilitate the lifting of the entire cover, Figure 1 As shown, a handle 42 is provided on the top of the cover plate; there are two handles 42 and they are arranged along the center line of the cover plate body 4. Such an arrangement enables hoisting using two hoisting lines to ensure the balance of the cover plate during the hoisting process, so that it can be perfectly embedded in the reserved equipment installation hole 11 on the floor.

[0031] Since the reserved equipment installation hole 11 on the floor is relatively large, the required cover plate body 4 is relatively large in size. In order to facilitate transportation and installation, the cover plate body 4 includes a plurality of cover plates 41, and two adjacent cover plates 41 are detachably connected; specifically, the detachable connection between the cover plates 41 can be mortise and tenon connection or bolt connection; as a preferred method, in order to reduce the installation steps and achieve the purpose of quickly installing the cover plate body 4, as shown in FIG. Figure 3 As shown, two adjacent cover panels 41 are hinged; by hinged connection of the two adjacent cover panels 41, the cover body 4 assembled by the cover panels 41 can be flipped and folded. When the cover body 4 needs to be installed, the cover panel 41 only needs to be flipped and unfolded to achieve the purpose of quickly installing the cover body 4; when not needed, the cover panel 41 is flipped and folded. The folded volume is small, which is convenient for transportation, and it occupies a small area for storage.
