Description

Technical Field

[0001] This utility model pertains to safety protection devices for building construction, specifically relating to an adjustable, fixed-type protective device for reserved openings in floor slabs. Background Technology

[0002] In building construction, various openings are pre-reserved in floor slabs to facilitate construction. As the number of building stories increases, the number of these openings on construction sites also increases, posing significant safety hazards and leading to frequent falls from heights. Therefore, effectively sealing these openings is crucial to preventing such accidents. Since the short side dimensions of common floor slab openings such as cable tray openings, aluminum formwork material transfer openings, etc., are all less than 500mm, the current protective measures for these openings involve using appropriately sized wooden beams to secure them inside the opening, and then nailing shelves to the beams as rigid protection. This method has good protective effects, but it also has significant drawbacks: it requires high precision in the dimensions of the installed wooden beams, which are prone to displacement and difficult to adjust; it is inconvenient to remove and restore the opening if needed; and the dimensions of the wooden beams and shelves are relatively fixed, making it difficult to adapt them to other openings after removal, resulting in low reuse rates.

[0003] To address the aforementioned issues, patent document CN222909516U discloses a protective structure for construction openings in floor slabs. It reveals that a cover plate is locked to the construction opening using bolts with locking plates. This solution offers high protection and is easy to install and remove. However, some problems exist in actual use: the bolt positions are relatively fixed, resulting in a narrow range of fit for opening sizes; and the length of the bolts extending beyond the cover plate surface after it is fixed affects construction. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing reserved opening protection structures and provide an adjustable fixed-shape protection device for reserved openings in floor slabs that has good protection effect, is easy to disassemble and assemble, and has a high reusability.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: an adjustable fixed protective device for reserved openings in floor slabs, including a protective plate and a buckle assembly. Several parallel adjusting grooves are spaced apart on the protective plate. The buckle assembly mainly consists of an adjusting bolt and an "L"-shaped adjusting sleeve. An anti-rotation plate is provided on the vertical tube of the adjusting sleeve. The anti-rotation plate and the horizontal tube of the adjusting sleeve are on the same side. The adjusting sleeve is located below the protective plate. The screw of the adjusting bolt passes through the adjusting groove from above the protective plate and is connected to the threaded sleeve of the vertical tube of the adjusting sleeve.

[0006] Optionally, the head of the adjusting bolt is flat, with an inner angular groove in the middle for rotation.

[0007] Optionally, the number of the buckle components is four, which are spaced apart at the four corners of the protective plate.

[0008] Optionally, the protective device further includes a bearing component, which mainly consists of a gasket with an "L" shaped cross-section and fasteners. The gasket has connecting holes on its long and short sides, and one side of the protective plate is placed on the long side of the gasket and fixed by fasteners.

[0009] Optionally, the protective plate has several mating holes along its edge.

[0010] The method of using this utility model is as follows: First, select a suitable adjusting groove on the protective plate according to the size of the opening, and install several buckle components on these adjusting grooves. Next, adjust the depth of the connection between the adjusting bolt and the vertical tube of the adjusting sleeve according to the thickness of the floor slab. Then, cover the reserved opening with the protective plate, move the adjusting bolt along the adjusting groove so that the anti-rotation plate on the vertical tube of the adjusting sleeve abuts against the side wall of the floor slab. Then, rotate the adjusting bolt by the handle to move the adjusting sleeve upward so that the horizontal tube of the adjusting sleeve is tightly pressed against the bottom of the floor slab, positioning the protective plate at the reserved opening. Finally, check the stability of the protective plate to complete the protection of the reserved opening.

[0011] The principle of this utility model is as follows: the protective plate covers the reserved opening, the buckle assembly is positioned and fixed, and the disassembly and assembly are convenient; the distribution position of the buckle assembly on the protective plate is changed by the adjustment groove to adapt to openings of different sizes, and the reuse rate is high; the combination of the adjusting bolt and the adjusting sleeve can accurately match the floor slab thickness of the reserved opening. By the horizontal tube of the adjusting sleeve tightly pressing against the bottom of the floor slab and the anti-rotation plate positioning the direction of the horizontal tube of the adjusting sleeve (to prevent the horizontal tube of the adjusting sleeve from rotating out of the bottom of the floor slab when the adjusting bolt is rotated), the protective plate is well positioned and fixed in the reserved opening, and the protective effect is good.

[0012] Compared with the prior art, the present invention has at least the following advantages: the present invention has good protective effect, is easy to disassemble and assemble, and has a high reusability. Attached Figure Description

[0015] refer to Figure 1-4 In this embodiment, an adjustable fixed-shape protective device for pre-reserved openings in floor slabs includes a protective plate 1 and a snap-fit ​​assembly 2. The protective plate is made of 2.5mm thick galvanized anti-slip patterned steel plate, commonly sized as 600mm×400mm or 900mm×400mm. Several parallel adjusting grooves 3 are spaced apart along the width of the protective plate, each groove being 18mm wide and 50mm from the edge of the plate at both ends. The snap-fit ​​assembly mainly consists of adjusting bolts 4 and "L"-shaped adjusting sleeves. The system consists of 5 components. An anti-rotation plate 6 is provided on the vertical tube of the adjusting sleeve. The anti-rotation plate and the horizontal tube of the adjusting sleeve are on the same side and are integrally formed. The adjusting sleeve is located below the protective plate. The screw of the adjusting bolt passes through the adjusting groove from above the protective plate and connects to the threaded sleeve of the vertical tube of the adjusting sleeve. A lifting ring can be fixed on the vertical tube of the adjusting sleeve on the opposite side of the anti-rotation plate.
