Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a temporary sealing component for small-diameter holes reserved in floor slabs. Background Technology

[0002] During construction, pre-reserved openings in floor slabs serve as important structural connection channels for equipment installation, pipeline laying, etc., bringing convenience to construction but also posing safety hazards. To ensure safety on the construction site and avoid accidents caused by pre-reserved openings in floor slabs, effective protective measures are necessary.

[0003] Currently, the commonly used temporary hole protection method is to simply cover the opening with wooden boards or steel mesh. These covering devices are not effectively fixed and are prone to displacement due to external forces, posing a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a temporary sealing component for small-diameter holes in floor slabs. This component aims to improve the safety and stability of temporary sealing of small-diameter holes at construction sites, thereby reducing safety risks caused by pre-reserved openings in floor slabs and creating a safer working environment for construction workers.

[0005] The technical objective of this utility model is achieved through the following technical solution:

[0006] A temporary sealing component for small-diameter holes in floor slabs includes a cover plate and a protruding post connected to the lower end face of the cover plate, and a protruding post sleeve adapted to the protruding post. The protruding post sleeve is sleeved on the protruding post, and a threaded connection hole is provided on the lower end side face of the protruding post. A stop bar is threadedly connected to the threaded connection hole, and the stop bar is used to block the protruding post sleeve.

[0007] Preferably, the cover plate is threadedly connected to the protruding post.

[0008] Preferably, the cross-section of the protrusion is circular or rectangular.

[0009] Preferably, the cover plate is a metal plate.

[0010] Preferably, the protruding post is a hollow tubular structure, and the wall thickness of the protruding post is not less than 8mm.

[0011] Preferably, the protrusion is made of stainless steel.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model provides a temporary sealing component for pre-reserved small-diameter holes in floor slabs. It is simple to use, easy to install and remove, allowing operators to quickly seal the pre-reserved holes. The protruding column fixes the cover plate in its position, improving its stability and reducing safety hazards. Furthermore, the protruding column sleeve can flexibly adapt to floor slab holes of different sizes and specifications, offering good adaptability. Attached Figure Description

[0017] 1. Cover plate; 2. Protruding post; 3. Protruding post sleeve; 4. Stop bar. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As a preferred embodiment of this utility model, such as Figure 1-Figure 2 As shown, this embodiment provides a temporary sealing component for small-diameter holes reserved in floor slabs, including a cover plate 1 and a protruding post 2 connected to the lower end face of the cover plate 1, and also includes a protruding post sleeve 3 adapted to the protruding post 2. The protruding post sleeve 3 is sleeved on the protruding post 2. A threaded connection hole is provided on the lower end side face of the protruding post 2. A stop rod 4 is threadedly connected to the threaded connection hole. The stop rod 4 is used to block the protruding post sleeve 3.

[0020] It should be noted that the protruding post 2 is used to cooperate with the holes existing in the floor slab, specifically, it passes through the holes. Therefore, the outer diameter of the protruding post 2 is close to the size of the holes. This can prevent the cover plate from having any space for movement during use. Therefore, a protruding post sleeve 3 is designed to cooperate with the protruding post 2, thereby adjusting the outer diameter of the protruding post 2 during use. There can be multiple protruding post sleeves 3, which can be flexibly adjusted according to actual needs. After the protruding post sleeve 3 is fitted onto the protruding post 2, a baffle 4 is threaded into the threaded connection hole to block the protruding post sleeve 3.

[0021] Depending on the load-bearing requirements above the hole, this utility model can also be made of concrete or wood. The length of the protruding column 2 is slightly greater than the thickness of the floor slab, and the cross-sectional size of the protruding column 2 is slightly smaller than the cross-sectional size of the reserved hole. By connecting the cover plate 1 and the protruding column 2, and placing the protruding column 2 into the reserved hole, the hole can be temporarily sealed.

[0022] In some embodiments, considering that the holes appearing on the floor slab may be regular shapes, such as circles or rectangles, or they may be irregular shapes, in order to better adapt to holes of various shapes, the cover plate 1 and the protruding post 2 are threadedly connected in this embodiment, so that protruding posts 2 of different shapes can be replaced, thereby better adapting to the holes on the floor slab.

[0023] In other embodiments, Figure 1 As shown, most commonly, the cross-section of the protrusion 2 is circular or rectangular.

[0024] In some preferred embodiments, in order to ensure the structural strength of the cover plate 1 and enable it to withstand higher external forces during use, the cover plate 1 in this embodiment is a metal plate, preferably a steel plate, stainless steel plate, or aluminum alloy plate.

[0025] In other embodiments, to facilitate handling and disassembly and reduce overall weight, the protruding post 2 in this embodiment is a hollow tubular structure. In order to facilitate the stable connection of the stop rod 4 and provide sufficient blocking force to the protruding post sleeve 3, the wall thickness of the protruding post 2 is required to be not less than 8mm.

[0026] In other embodiments, to facilitate the fitting of the protruding post 3, the protruding post 2 in this embodiment is made of stainless steel.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
