Description

Technical Field

[0001] This utility model relates to the field of building construction technology. Background Technology

[0002] For sealing openings through floor slabs, a suspended-hole construction technique is generally used. This technique involves erecting timber and scaffolding beneath the floor slab to be sealed, along with the construction of the bottom formwork. A release agent is applied to the formwork surface. Since the formwork is placed under the opening and its design dimensions are larger than the opening size, sponge strips are used to seal the gaps between the formwork and the floor slab to ensure a tight seal and prevent grout leakage. After the formwork is erected, micro-expansion fine aggregate concrete is poured into the opening in two stages. The first pour reaches two-thirds of the slab thickness and is thoroughly compacted to avoid voids. After the first pour has initially set, the second pour is performed. A minimum of 7 days of curing time is required before the formwork and scaffolding can be removed. The presence of the scaffolding significantly hinders construction work in the space below.

[0021] This embodiment is a component for sealing openings in building floor slabs. Therefore, in this embodiment, the upper and lower positions refer to the direction of gravity of the building, and extend sequentially to the terms used in the claims.

[0022] A sealing component for a floor slab opening is disclosed. This component is installed using a top-down suspension method and includes a reusable upper component 10 and lower component 20, a bottom formwork 30, two long screws, and a sealing component 40 as an embedded part. The upper component 10 is located above the floor slab opening 80, and the lower component 20 is located below the floor slab opening 80. The sealing component 40 serves as an intermediate transition connector, effectively connecting the upper component 10 and the lower component 20 mechanically, thereby fixing the bottom formwork 30. This effectively fits the bottom formwork 30 against the bottom of the opening, forming an effective grouting space. The following paragraphs will describe this component in detail with reference to specific embodiments.

[0023] refer to Figures 1 to 3 The series illustrates the composition of this sealing assembly. The bottom mold 30 is made of aluminum alloy. Different sizes and profiles of the bottom mold 30 are selected based on the contour of the opening. For example, when the opening has a diameter of 15 cm, the bottom mold 30 has a diameter of 25 cm; that is, the bottom mold 30 is much larger than the opening. Furthermore, the aluminum alloy template is made of thick aluminum plate, for example, an aluminum plate with a thickness of not less than 10 mm. A through hole, i.e., a bolt hole for hoisting, is provided in the center of the bottom mold 30 for fixing the sealing component 40.

[0024] The sealing component 40 is an injection-molded or nylon part, with an overall dumbbell-shaped structure. It has a rod-like middle section and enlarged ends. A water-stop ring 41 is provided on the rod-like middle section of the sealing component 40. This water-stop ring 41 is a thin sheet-like structure with a significantly increased area. The connecting portions 42 at both ends of the sealing component 40 are enlarged, meaning that threaded holes are provided at these connecting portions 42. These threaded holes can be formed by nuts embedded in the injection-molded sealing component 40, or they can be directly machined from the nylon part.

[0025] Furthermore, the aforementioned sealing component 40 can also be a metal component, but metal components are expensive and their function is equivalent to that of the aforementioned non-metallic materials, so their use is not recommended.

[0026] The upper component 10 is a multi-point support structure composed of multiple Z-shaped support legs. Specifically, the upper component 10 is integrally formed by stamping a 5-6 mm thick steel plate. The multiple support legs after forming are arranged in a circle. This embodiment shows the effect of four support legs. The four support legs of the upper component 10 converge at the flat plate. The flat plate has a bolt hole in the center. The bolt hole is used to cooperate with the first long screw 50. A pair of nuts are used to fasten it at the top and bottom of the flat plate. After fastening, the first long screw 50 and the upper component 10 become one piece. Meanwhile, the lower end of the first long screw 50 is threadedly fastened to the top connecting part 42 on the sealing component 40. That is to say, in use, the upper component 10 is supported by the four support legs on the floor around the opening, and the sealing component 40 is hoisted by the first long screw 50 in the center. After hoisting, the height of the sealing component 40 is adjusted by adjusting the height of the first long screw 50. After adjustment, the high point of the sealing component 40 is equal to the upper surface of the floor, thus completing the installation of the upper component 10.

[0027] The lower component 20 is similar in structure to the upper component 10, consisting of eight Z-shaped support legs and a flat plate. It is also a stamped steel plate part with bolt holes that engage with the second long screw 60. Nuts are used to connect the upper component 10 and the second long screw 60. Simultaneously, the upper end of the second long screw 60 is mechanically fixed to the lower end of the sealing component 40. After fixing, the bottom mold 30 is pressed down by tightening the nuts, so that the central part of the bottom mold 30 is pressed against the lowest end of the sealing component 40. Tightening the nuts further presses the four support legs of the lower component 20 against the edge of the bottom mold 30, providing support for the template. Depending on the application, the number of support legs can be increased to provide bottom support for the template.

[0028] A construction structure for sealing openings in building floor slabs, referenced Figure 4 and Figure 5 The construction method is as follows: Step 1: Process the opening 80 to be sealed. Specifically, perform a circular chisel to create a cone-shaped opening that is wider at the top and narrower at the bottom. After cleaning the opening, select a sealing component 40 of appropriate size and proceed with the construction.

[0029] Step two: Construction is carried out above the floor slab. The upper component 10, the first long screw 50, the sealing component 40 and the second long screw 60 are assembled. After the initial assembly, it is placed above the opening. The height of the sealing component 40 is adjusted by adjusting the position of the first long screw 50. After adjustment, the high point of the sealing component 40 is equal to the upper surface of the floor slab, thus completing the installation of the upper component 10.

[0030] Step 3: Install the bottom formwork 30 below the floor slab. Install the bottom formwork 30 on the second long screw 60 from bottom to top, and use nuts to initially tighten the bottom formwork 30. After tightening, the middle of the bottom formwork 30 abuts against the sealing component 40, and the four sides make initial contact with the opening. Then, install the lower component 20 on the second long screw 60 and use fastening nuts to tighten the lower component 20. After tightening, the ends of the four support legs of the lower component 20 abut against the four sides of the bottom formwork 30, pressing the bottom formwork 30 tightly against the lower surface of the floor slab around the opening, forming an effective bottom support.

[0031] Step four: After the formwork is completed, pour 70 cubic meters of micro-expansion fine aggregate concrete into the opening in two stages. The first pour should reach two-thirds of the slab thickness and be thoroughly compacted to avoid voids. After the first concrete has initially set, pour the second concrete. The curing time after pouring should be no less than 7 days. During the curing period, the foundation construction in the space above and below the floor slab, such as the installation of water, electricity, and heating systems, should not be affected. Furthermore, this embodiment reduces the workload by more than half compared to traditional scaffolding construction, significantly lowering the project cost.

[0032] Finally, remove the mold.

[0033] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Without departing from the spirit of the present utility model, all modifications and improvements to the present utility model by those skilled in the art should fall within the protection scope defined by the claims of the present utility model.
