Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, and in particular relates to a switchable and airtight cable laying hole cover device and construction method. Background Technology

[0002] Layout holes are pre-reserved openings during building construction to transfer measurement control points between floors, ensuring axis alignment and structural accuracy. Their main function is to vertically transfer coordinate points (such as axes and elevations) from lower or ground floors to upper floors, preventing structural deviations caused by accumulated errors in floor height in high-rise buildings. By projecting a baseline upwards from these lower-floor openings using a theodolite or total station, alignment of axes across floors is achieved, replacing the traditional plumb line method and reducing error accumulation in high-rise buildings over 50 meters. During the main building construction, layout holes need to be pre-reserved. This device can be used to close or open these holes, ensuring seamless transitions between construction phases, allowing for main structure construction on the upper level while finishing work on the lower level can proceed. It also prevents water and other debris generated during main structure construction from entering lower floors and affecting other construction phases. The protection of pre-reserved layout holes in the main construction of buildings is a problem that needs to be considered in every project. Traditional layout holes are exposed to the outside for a long time, and rainwater and indoor water can easily seep into the lower floors through the holes. This can lead to quality problems when parallel or overlapping construction is carried out below (such as floor slab leakage, damp ceilings in the lower floors, etc.), and debris and tools can easily fall in, causing construction safety accidents. How to quickly, economically and comprehensively solve the construction management problem of layout holes is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0025] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0026] This invention relates to an openable and sealable wire-laying hole cover device and construction method. The openable and sealable wire-laying hole cover device includes a base plate 1 and a cover plate 2 that can be interlocked. The base plate 1 has a through hole 11 that matches the wire-laying hole. The cover plate 2 can cover the through hole 11. By movably connecting the base plate 1 and the cover plate 2, the open and closed states of the wire-laying hole can be switched without affecting the use of the wire-laying hole. It can also shield the safety risks at the wire-laying hole and ensure the quality of the project.

[0027] The switchable and sealable wire feeding hole cover device includes a base plate 1, a cover plate 2, and a connector 3. The base plate 1 is an aluminum plate with a through hole 11 in the center. The size of the through hole 11 matches the wire feeding hole, which can fully expose the wire feeding hole. The cover plate 2 is rotatably connected to the base plate 1 on one side and has a handle 21 on its upper surface. It can cover the through hole 11 on the base plate 1 and seal the wire feeding hole. The device also includes a connector 3, which is located on the edge or four corners of the base plate 1 and can fix the base plate 1 to the outside of the wire feeding hole. The connector 3 can usually be bolts for easy disassembly.

[0028] To ensure the wire release port is waterproof and odor-proof, waterproof rubber pads can be installed on the base plate 1 and cover plate 2 of the openable and sealable wire release hole cover device. The base plate rubber waterproof pad 12 is located at the edge of the bottom surface of the base plate 1, or covers the area of ​​the bottom surface of the base plate 1 other than the through hole 11; the cover plate rubber waterproof pad 22 is located at the edge of the cover plate 2, or covers the area of ​​the bottom surface of the cover plate 2, so that when the openable and sealable wire release hole cover device covers the wire release hole and remains closed, it can maintain a sealed state, preventing air circulation at the wire release hole and preventing liquid from passing through the wire release hole. In some embodiments of the present invention, the base plate rubber waterproof pad 12 is strip-shaped, covering the edge of the base plate 1; the cover plate rubber waterproof pad 22 is arc-shaped, covering the edges of the cover plate 2 respectively, with the arc-shaped rubber waterproof pad providing a larger protective area.

[0029] One side of the cover plate 2 is hinged to the base plate 1, and the opposite side of the cover plate 2 is provided with a buckle that can be fastened to the edge of the base plate 1, facilitating the opening and closing of the cover plate 2. The hinge and fastening methods of the cover plate 2 and the base plate 1 can adopt conventional schemes, ensuring that the cover plate 2 can switch between open and closed states with the base plate 1, and that the cover plate 2 or the cover plate rubber waterproof gasket 22 can be in close contact with the base plate 1 when closed. In some embodiments of the present invention, the cover plate 2 and the base plate 1 are connected by a hinge structure; alternatively, a matching fastening structure can be provided at the opposite positions of the base plate 1 and the cover plate 2, and the opening and closing states of the cover plate 2 and the base plate 1 can be switched through the cooperation of the two parts of the fastening structure.

[0030] Depending on the size of the through hole 11, the switchable and hermetic wire-laying hole cover device includes multiple models, making it suitable for wire-laying holes of different sizes. Specifically, different models of switchable and hermetic wire-laying hole cover devices may include base plates 1, cover plates 2 and through holes 11 of different sizes, or they may include base plates 1 and cover plates 2 of the same size, only the size of the through hole 11 is different.

[0031] The construction process of the switchable and sealable cable outlet cover device includes the following steps:

[0032] S1: Manufacturing multiple models of switchable and sealable wire feeding hole cover devices;

[0033] S2: Confirm the site requirements and the location and size of the wire laying hole, and fix a suitable type of switchable and airtight wire laying hole cover device at the location of the wire laying hole.

[0034] S3: When not using the wire feeding hole, keep the switchable and sealable wire feeding hole cover device in the closed state; when using the wire feeding hole, open the cover of the switchable and sealable wire feeding hole cover device.

[0035] S4: When the wire feeding hole is no longer needed, remove the switchable and sealable wire feeding hole cover.

[0036] The openable and sealable cable hole cover device protects cable holes, improving the construction environment and safety. It prevents personnel from accidentally getting their feet stuck or tools and debris from falling into the holes, avoiding injuries from falling objects. It also reduces safety hazards during construction. Furthermore, it prevents cable holes connected to multiple floors from becoming channels for dust and odors to spread between floors, maintaining a clean environment in each construction area. The openable and sealable cable hole cover device protects the structure and construction quality, preventing impact and contamination of the concrete around the hole, maintaining the integrity of the floor slab structure, and preventing edge damage and cracks. It blocks dust, mortar, and construction waste from entering the hole, avoiding difficulties in later cleaning, and preventing the accumulation of debris inside the hole, which could affect the sealing tightness. It prevents rainwater and construction water from flowing into the hole, reducing the risk of electric shock and moisture damage to the structural base. This proactive protection creates favorable conditions for subsequent sealing, waterproofing, and ceiling construction, reducing the risk of leakage.

[0037] In traditional construction, a linear construction pattern of "completing one step before moving on to the next" is strictly followed, with the main structure inspected before secondary structure, decoration, and mechanical and electrical engineering work. However, with social development and people's pursuit of quality, economy, and efficiency, more and more projects are adopting a "process interleaving" approach, using parallel or overlapping construction methods. The installation and dismantling of this switchable, airtight wire-layout hole cover device is implemented using this process interleaving method. This significantly shortens the overall construction period, reduces waiting time for cross-disciplinary work, and especially accelerates the progress of subsequent key processes such as waterproofing and decoration. It eliminates the need for special protection of the wire-layout hole openings, reducing the extra workload for later hole cleaning and repair, avoiding project delays, preventing damage and rework caused by unprotected holes, reducing material and labor costs, enabling continuous construction, avoiding idle labor losses, and reducing construction costs.

[0038] The switchable and sealable cable-laying hole cover device can provide a sealed protection for the cable-laying hole during construction. It can be opened at any time when needed, facilitating subsequent parallel or overlapping construction. The device also features simple operation, convenient construction, and detachability. Furthermore, all components are made from common materials found on the construction site, allowing for easy replacement as needed, recycling of waste materials, and portability.

Buckles are provided on opposite sides of the cover plate to engage with the edge of the base plate. The connectors are bolts located at the four corners of the base plate to fix the base plate to the outside of the cable-laying hole. A rubber waterproof pad is provided at the bottom of the base plate, positioned at the bottom edge of the base plate. A rubber waterproof pad is also provided at the bottom of the cover plate, positioned at the edge of the cover plate. The device is used in the following steps:
