Description

Technical Field

[0001] This utility model belongs to the field of floor slab side formwork technology, specifically relating to a pre-embedded structure for the material transfer hole of the floor slab side formwork. Background Technology

[0002] After the floor slab marking holes and material transfer holes of related technologies are poured, gaps easily form at the junction of the hole walls and the concrete. Furthermore, the smooth surface of the hole walls makes it difficult for waterproofing materials to adhere effectively. During floor tiling in renovation projects, moisture can easily seep through these gaps to the floor below, affecting normal use. At the same time, the traditional vertical placement of through holes concentrates the load, causing stress concentration in the concrete around the hole walls, leading to cracking and further increasing the risk of water seepage.

[0003] Traditional embedded components are complex to install and have weak connections, making them prone to displacement or detachment during concrete pouring, which affects the embedding effect. Furthermore, the lack of structural reinforcement design for through-hole areas makes these areas weak points in the floor slab structure, reducing the overall load-bearing capacity and safety of the floor slab. Utility Model Content

[0004] This utility model provides a pre-embedded structure for the material transfer hole of the side formwork of the floor slab. The inclined hole wall makes the concrete pouring more compact and reduces gaps; the prefabricated no-chiseling layer increases the roughness of the hole wall, improves the adhesion, and enhances the waterproof effect.

[0005] The embedded structure includes: a floor slab body, on which a through hole is formed; characterized in that the wall of the through hole is inclined; and the upper opening area of ​​the through hole is larger than the lower opening area.

[0006] The surface of the through hole wall is provided with a friction surface;

[0007] A precast slab is fixed at the lower opening of the through hole; an installation hole is provided on the precast slab, and a butt cap is fixed on the floor slab body; the installation hole of the precast slab passes through the butt cap and is fixed to the floor slab body on the lower side of the through hole by a snap-fit ​​assembly.

[0008] Preferably, the friction surface of the through hole wall is a prefabricated roughened layer; the surface of the prefabricated plate is set as the friction surface.

[0009] Preferably, the friction surface of the through hole wall is serrated, or water ripple-shaped, or has multiple protrusions of different shapes.

[0010] Preferably, the snap-fit ​​assembly is provided with a snap-fit ​​connector, and a mating cap adapted to the snap-fit ​​connector is fixed on the floor slab body;

[0011] The mounting holes of the precast slab pass through the docking caps, and the snap-fit ​​parts engage with the docking caps to fix the precast slabs to the floor slab body.

[0012] Preferably, the snap-fit ​​component is provided with a column, one end of which is provided with a top cap, and the other end of which is provided with a tapered end; the position of the column near the top cap is a locking section;

[0013] A boss is provided in the middle of the column, and a positioning groove is provided between the boss and the locking section;

[0014] The section between the boss and the tapered end is the guide section.

[0015] Preferably, the cross-sectional area of ​​the precast slab is larger than the cross-sectional area of ​​the bottom of the through hole.

[0016] Preferably, a wire mesh is embedded inside the floor slab body near the through hole.

[0017] Preferably, the inclination angle of the hole wall is 45-60 degrees.

[0019] As can be seen from the above technical solutions, this utility model has the following advantages:

[0020] This utility model provides a pre-embedded structure for the side formwork layout holes and material transfer holes in floor slabs. Through the design of inclined hole walls, a prefabricated no-chamber layer, large-size prefabricated slabs, and their surface friction surfaces, the inclined hole walls ensure denser concrete pouring and reduce gaps. The prefabricated no-chamber layer increases the roughness of the hole walls, improving adhesion and enhancing waterproofing. Using interlocking components, through the cooperation of columns, caps, and conical ends, a quick, precise, and secure connection between the prefabricated slab and the floor slab body is achieved, preventing displacement and detachment. Embedding wire mesh inside the floor slab body enhances the strength of the through-hole area, resulting in more even load distribution, reduced stress concentration, improved structural stability in the through-hole area, and overall floor slab safety. The prefabricated slabs are recyclable, improving resource utilization. Attached Figure Description

[0030] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0031] like Figures 1 to 5 As shown, the pre-embedded structure for the side formwork layout hole and material transfer hole of the present invention includes: floor slab body 1. In this embodiment, the floor slab body 1 is a component of the building floor. In this pre-embedded structure, it not only undertakes conventional structural functions, but also provides space for the layout hole and material transfer hole, becoming the basis for construction operations such as layout and material transfer.

[0032] The through-hole 2 on the floor slab body 1 in this embodiment serves both as a surveying and material transfer hole. During construction, the surveying hole is used for surveying and setting out lines, allowing construction workers to transfer control lines from the ground to the next floor, ensuring the accuracy of the planar position and dimensions of various parts of the building. The material transfer hole is used for the vertical transportation of construction materials, facilitating the transfer of materials from the next floor to the next, thus improving construction efficiency. The through-hole 2 is provided on the floor slab body; the hole wall of the through-hole 2 is inclined, and the upper opening area is larger than the lower opening area. This design facilitates better encapsulation of the embedded structure by the concrete at the hole wall during concrete pouring, reducing gaps, and also facilitates subsequent formwork removal and extraction of the embedded pieces.

[0033] In this embodiment, the surface of the through hole 2 on the floor slab body 1 is set as a prefabricated no-roughening layer 3, i.e., a friction surface. This treatment method changes the traditional smooth concrete surface, and a rough surface can be formed without subsequent manual roughening.

[0034] In this embodiment, the friction surface of the through-hole 2 wall is serrated, wavy, or has multiple protrusions of different shapes. These shaped friction surfaces can greatly increase the surface area of ​​the hole wall, resulting in a larger contact area when it comes into contact with filling materials, sealing materials, or decorative materials.

[0035] The floor slab body 1 mates with the precast slab 4 at the lower opening of the through hole 2. The precast slab 4 is fixed to the floor slab body 1 at the lower opening of the through hole 2 via mounting holes and snap-fit ​​components. The cross-sectional area of ​​the precast slab 4 is larger than the cross-sectional area of ​​the lower opening of the through hole 2. This allows the precast slab 4 to be attached to the lower opening of the through hole 2. Of course, depending on actual needs, the cross-sectional area of ​​the precast slab 4 can be the same as the cross-sectional area of ​​the lower opening of the through hole 2, so that the precast slab 4 is snapped into the lower opening of the through hole 2.

[0036] The surface of the precast slab 4 is designed as a friction surface. The cross-sectional area of ​​the precast slab 4 is larger than the cross-sectional area of ​​the lower opening of the through hole 2, which allows the precast slab 4 to adhere to the lower opening of the through hole 2 over a large area, resulting in more thorough contact with the floor slab body 1. During the concrete pouring process, the bonding surface between the precast slab 4 and the concrete increases, and the poured concrete is firmly embedded in the floor slab, effectively preventing the precast slab 4 from shifting or falling off, and ensuring the integrity of the embedded structure.

[0037] The cross-sectional area of ​​the precast slab 4 is the same as the cross-sectional area of ​​the lower opening of the through hole 2. The precast slab 4 can be precisely inserted into the lower opening of the through hole 2 to form a tight fit structure. When installing the precast slab 4, a simple operation can accurately position the precast slab 4, ensuring that the precast slab 4 is aligned with the lower opening of the through hole 2, thus guaranteeing the quality of subsequent construction.

[0038] It should be further explained that the inclined hole wall and the prefabricated no-chamber layer of through-hole 2 give it stronger seepage prevention capabilities compared to traditional through-hole 2 after construction. The inclined hole wall and the no-chamber layer increase the contact area and friction between the hole wall and concrete, waterproofing materials, etc., effectively preventing water penetration and avoiding water seepage when laying floor tiles in subsequent decoration projects. This protects the finished decoration work below and improves the waterproofing performance and service quality of the building.

[0039] In this embodiment, the inclination angle of the hole wall is 45-60 degrees. This allows the concrete to flow more smoothly into the through-hole 2 during pouring, reducing concrete accumulation and blockage within the hole. It also facilitates the insertion of a vibrator into the hole for compaction, ensuring the density of the concrete. This inclination angle allows the force to be transmitted more evenly to the floor slab body 1 when the through-hole 2 is under load, reducing stress concentration and improving the shear and bending resistance of the structure surrounding the through-hole 2. PP rigid plastic has good corrosion resistance, water resistance, and a certain degree of flexibility. In embedded structures, it can resist the erosion of various chemicals in the concrete. Furthermore, during the concrete solidification process, its flexibility can accommodate a certain degree of deformation, preventing the precast slab 4 from cracking or separating from the concrete due to concrete shrinkage.

[0040] Precast slab 4 is made of either PP rigid plastic or UPVC rigid plastic. UPVC rigid plastic possesses excellent corrosion resistance, weather resistance, and high strength. It maintains stable performance under harsh environmental conditions and is not prone to aging or deformation. In embedded structures, it can withstand the pressure during concrete pouring and various external forces during subsequent use, ensuring the structural integrity of precast slab 4.

[0041] During the concrete pouring process, the precast slab 4 is snapped together with the floor slab body 1. After the concrete solidifies, the precast slab 4 is removed to form a rough surface, which further enhances the impermeability of this part. This allows the floor slab body 1 to have basic structural functions while solving the problem of easy water seepage in the layout hole and material transfer hole.

[0042] The snap-fit ​​assembly in this embodiment is provided with a snap-fit ​​component, and a mating cap adapted to the snap-fit ​​component is fixed on the floor slab body 1; the mounting hole of the precast slab 4 passes through the mating cap, and the snap-fit ​​component snaps into the mating cap, so that the precast slab 4 is fixed on the floor slab body 1.

[0043] Specifically, the snap-fit ​​connector and the mating cap work together to achieve a quick and stable connection between the precast slab 4 and the floor slab body 1, ensuring that the precast slab 4 can be reliably fixed to the floor slab body 1 after installation, meeting the usage requirements of the embedded structures such as the side formwork layout holes and material transfer holes of the floor slab. Compared with other connection methods, such as welding or complex bolt connections, the snap-fit ​​connection is more convenient, improves construction efficiency, and ensures the stability and reliability of the connection.

[0044] like Figure 6 As shown, this embodiment includes a column 11 with a cap 12 at one end. The column 11 serves as the main structure of the snap-fit ​​component, connecting the cap 12, the conical end 13, the boss 14, and other parts. It also provides guidance and support during the insertion of the mating cap. The shape and size design of the column 11 ensures the precision of the fit between the snap-fit ​​component and the mating cap, allowing for a smooth snap-fit ​​process. Simultaneously, it ensures that it can withstand certain external forces without deformation during use, thus guaranteeing the stability of the connection between the precast slab 4 and the floor slab body 1. The cap 12 facilitates operation by construction personnel during snap-fit ​​installation, such as pressing or tapping the cap 12 to allow the snap-fit ​​component to smoothly enter the mating cap.

[0045] The other end of the column 11 is provided with a tapered end 13; the tapered end 13 facilitates the insertion of the snap-fit ​​component into the mating cap. During insertion, the tapered end 13 guides the column 11 smoothly into the mating cap, reducing resistance during insertion. Even if the entrance of the mating cap has some deviation or irregularity, it can be easily aligned and inserted. The column 11 near the top cap 12 is a locking section 15; after the snap-fit ​​component is inserted into the mating cap, it forms a tight fit with the inner wall of the mating cap, preventing the snap-fit ​​component from coming out of the mating cap. A boss 14 is provided in the middle of the column 11. The boss 14 serves two purposes: firstly, as a positioning marker, helping construction personnel determine whether the snap-fit ​​component is inserted into the correct position during installation; secondly, the boss 14 also increases the friction between the snap-fit ​​component and the mating cap, improving the stability of the connection. The positioning groove 16 between the boss 14 and the locking section 15 can cooperate with the corresponding protrusion or structure on the mating cap during installation to achieve precise positioning of the snap-fit ​​component in the mating cap, ensuring that the snap-fit ​​component is installed in place and at the correct angle. The guide section between the boss 14 and the tapered end 13 works together with the tapered end 13 during the insertion of the snap-fit ​​into the mating cap to provide a smoother guide for the insertion of the column 11, making it easier for the column 11 to enter the mating cap, and guiding the material of the mating cap to undergo appropriate deformation during the insertion process so as to better cooperate with the snap-fit.
