Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building application technology, specifically relating to the sealing structure at the cavity end of a ribbed hollow floor slab. Background Technology

[0002] Compared to cast-in-place reinforced concrete, which is heavy and prone to shrinkage cracks, ribbed hollow floor slabs have advantages such as prefabricated components being processed in factories, stable quality, reduced labor intensity on construction sites, and reduced environmental pollution. They also feature hollow floor slabs, reduced floor slab weight, reduced steel reinforcement usage, and good overall integrity of cast-in-place structures.

[0003] Ribbed cavity floor slabs also require a sealing solution during construction. This means that the internal cavities (ventilated cavities) of the completed ribbed cavity floor slab need to provide ventilation and heat dissipation. To achieve these ventilation and heat dissipation functions, a ribbed cavity floor slab structure must be designed to ensure complete sealing.

[0004] Therefore, based on the above problems, this utility model provides a sealing structure for the cavity end of a ribbed cavity floor slab. Utility Model Content

[0005] Purpose of the utility model: The purpose of this utility model is to provide a sealing structure at the cavity end of a ribbed cavity floor slab, thereby solving the problems existing in the prior art.

[0006] Technical Solution: The cavity end sealing structure of the ribbed hollow floor slab of this utility model includes a base plate, a hollow transition box, a cover plate, a vent, and an air inlet. The inner wall of the upper end face of the hollow transition box is provided with a limiting groove. One side of the cover plate is provided with a limiting boss that matches the limiting groove. The surface of the limiting groove is coated with a first sealing layer, and the outer wall of the limiting boss is coated with a second sealing layer. The limiting boss is located inside the limiting groove, and the first and second sealing layers are used to seal the contact surface between the limiting groove and the limiting boss.

[0007] In this technical solution, the limiting slot is configured as an L-shape or a U-shape.

[0008] In this technical solution, the limiting boss is configured as a quadrilateral.

[0009] In this technical solution, the first sealing layer and the second sealing layer include, but are not limited to, concrete sealant for building construction and polyurethane foam sealant.

[0010] Compared with existing technologies, the beneficial effects of the cavity end sealing structure of the ribbed hollow floor slab of this utility model are as follows: 1. Its design structure is reasonable, which facilitates manufacturing and pre-assembly or on-site assembly, improves the construction progress, and the overall modular design also facilitates transportation; 2. By adopting the above technical solutions, the sealing of the ribbed hollow floor slab after construction is achieved. At the same time, the combination of the ribbed hollow floor slab with the ventilation system improves the ventilation effect, replaces the previous method of separately erecting a ventilation system, reduces the self-weight of the structure, and reduces costs. It conforms to the national policy of energy conservation, emission reduction and sustainable development, saves space at the bottom of the floor slab, and has a more beautiful visual effect.

[0020] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The cavity end sealing structure of the ribbed hollow floor slab shown includes a base plate 10, a hollow transition box 20, a cover plate 30, a vent 40, and an air inlet 50.

[0023] The upper end face of the hollow transition box 20 is provided with a limit groove 201.

[0024] One side of the cover plate 30 is provided with a limiting boss 301 that matches the limiting slot 201.

[0025] The surface of the limiting slot 201 is coated with a first sealing layer 202.

[0026] The outer wall of the limiting boss 301 is coated with a second sealing layer 302;

[0027] The limiting boss 301 is located inside the limiting groove 201, and the first sealing layer 202 and the second sealing layer 302 are used to seal the contact surface between the limiting groove 201 and the limiting boss 301.

[0028] The working principle is as follows: First, a first sealing layer 202 is applied to the surface of the limiting slot 201. Then, a second sealing layer 302 is applied to the surface of the limiting boss 301. Finally, the limiting boss 301 on one side of the cover plate 30 is vertically inserted into the limiting slot 201. After construction, the base plate 10, the hollow transition box 20, and the cover plate 30 form a sealed structure. The ventilation system is fixed to 50 through pipes (neither the ventilation system nor the pipes are shown in the diagram, which does not affect the disclosure of the technical solution of this application). The hollow transition boxes 20 are sealed in series through pipes (neither the pipes are shown in the diagram, which does not affect the disclosure of the technical solution of this application). This forms a sealed ribbed hollow floor slab cavity, realizing the corresponding ventilation and exhaust functions.

[0029] In addition, preferably as follows Figure 1 The limiting slot 201 shown is set in an L-shape, as follows: Figure 4 The limiting slot 201 shown is set in a U-shape, so that the above structure can quickly position the hollow transition box 20 and the cover plate 30 during construction and assembly, and achieve complete sealing in combination with the first sealing layer 202 and the second sealing layer 302.

[0030] In addition, the limiting boss 301 is preferably set as a quadrilateral such as a rectangle or a square, so that during construction, it can be combined with the limiting slot 201 to achieve rapid positioning between the hollow transition box 20 and the cover plate 30.

[0031] In addition, the first sealing layer 202 and the second sealing layer 302 preferably include, but are not limited to, concrete sealant for building construction and polyurethane foam sealant, to achieve reliable fixing and sealing of the contact surface between the limiting boss 301 and the limiting slot 201, thereby achieving the corresponding sealing and ventilation functions.

[0032] It should be noted that, in this document, terms such as "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
