Description

Technical Field

[0001] This utility model belongs to the field of cavity floor slab application technology, specifically relating to a high-temperature resistant structure for prefabricated cavity floor slabs. Background Technology

[0002] Precast hollow slabs refer to precast concrete slabs made by casting sections using recycled aggregate concrete as the base building material during the precast assembly process. This maintains a good ratio between structural strength and overall weight, thereby achieving the goals of saving materials and reducing self-weight.

[0003] Buildings often require fire-fighting smoke extraction or ventilation. Current methods involve adding corresponding smoke extraction or ventilation ducts, which increases construction costs and extends the construction period. Prefabricated hollow floor slabs, however, can solve these problems by adding appropriate through channels.

[0004] Flue gas is typically high-temperature, and its long-term effects can corrode the inner walls of hollow floor slabs. Furthermore, the particulate matter in the flue gas can also erode the inner walls, thus affecting their integrity. Therefore, it is necessary to isolate the passing high-temperature flue gas to prevent damage to the hollow floor slab.

[0005] Therefore, based on the above problems, this utility model provides a prefabricated cavity floor slab high-temperature resistant structure. Utility Model Content

[0006] Purpose of the utility model: The purpose of this utility model is to provide a high-temperature resistant structure for prefabricated hollow floor slabs, and to solve the technical problems existing in the ventilation and smoke exhaust of prefabricated hollow floor slabs in the prior art.

[0007] Technical solution: The present invention relates to a prefabricated hollow floor slab with a high-temperature resistant structure, comprising a central hollow box, a lower cover plate, and an upper cover plate. Two sets of high-temperature resistant partitions are symmetrically attached to the inner wall of the central hollow box. A lower cover plate high-temperature resistant partition is attached to the surface of the symmetrical center line of the lower cover plate, and an upper cover plate high-temperature resistant partition is attached to the surface of the symmetrical center line of the upper cover plate. A lower cover plate through groove and a lower cover plate high-temperature resistant partition through groove are symmetrically arranged within the lower cover plate and the lower cover plate high-temperature resistant partition. A central hollow box through groove and a high-temperature resistant partition through groove are symmetrically arranged within the central hollow box and the high-temperature resistant partition.

[0008] In this technical solution, the high-temperature resistant partition, the lower cover plate high-temperature resistant partition, and the upper cover plate high-temperature resistant partition are made of heat-resistant alloy steel plates.

[0009] The prefabricated cavity floor slab high-temperature resistant structure of this technical solution further includes a first adhesive layer, a second adhesive layer, and a third adhesive layer, which are respectively coated on one side of the high-temperature resistant partition layer, the lower cover plate high-temperature resistant partition layer, and the upper cover plate high-temperature resistant partition layer.

[0010] Compared with the prior art, the beneficial effects of the prefabricated hollow floor slab high-temperature resistant structure of this utility model are as follows: 1. The corresponding design of the two sets of high-temperature resistant partitions, the lower cover plate high-temperature resistant partition, the lower cover plate through groove, the lower cover plate high-temperature resistant partition through groove, the middle hollow box through groove, and the high-temperature resistant partition through groove can isolate high-temperature flue gas and prevent corrosion of the inner wall surfaces of the middle hollow box, the lower cover plate, and the upper cover plate, thus ensuring the safety of the middle hollow box, the lower cover plate, and the upper cover plate in conventional design and use; 2. The two sets of high-temperature resistant partitions and the lower cover plate high-temperature resistant partition adopt a patch-mount design, which facilitates on-site construction and assembly and shortens the construction time.

[0024] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0025] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 The prefabricated hollow floor slab high-temperature resistant structure shown includes a central hollow box 100, a lower cover plate 101, and an upper cover plate 102.

[0026] The inner wall of the hollow box 100 is symmetrically fitted with two sets of high-temperature resistant partitions 10.

[0027] A high-temperature resistant partition 11 is attached to the surface of the symmetrical center line of the lower cover plate 101.

[0028] A high-temperature resistant partition 12 is attached to the surface of the symmetrical center line of the upper cover plate 102.

[0029] The lower cover plate 101 and the lower cover plate high-temperature resistant partition 11 are symmetrically provided with lower cover plate through grooves 1011 and lower cover plate high-temperature resistant partition through grooves 11A.

[0030] The hollow box 100 and the high-temperature resistant partition 10 are symmetrically provided with a hollow box groove 1001 and a high-temperature resistant partition groove 10A.

[0031] The two end faces of the high-temperature resistant partition 10 after installation are respectively formed into a slope structure. The contact surfaces of the high-temperature resistant partition 11 of the lower cover plate, the high-temperature resistant partition 12 of the upper cover plate and the high-temperature resistant partition 10 are respectively set into a slope structure. After assembly, the two sets of high-temperature resistant partitions 10 and the connection surfaces of the high-temperature resistant partition 11 of the lower cover plate and the high-temperature resistant partition 12 of the upper cover plate respectively form a sealed structure to prevent the leakage of flue gas and its entry into the space between the intermediate hollow box 100, the lower cover plate 101 and the upper cover plate 102.

[0032] In addition, the high-temperature resistant partition 10, the high-temperature resistant partition 11 of the lower cover plate, and the high-temperature resistant partition 12 of the upper cover plate are preferably made of heat-resistant alloy steel plates. On the one hand, they are easy to manufacture and process, and on the other hand, they have excellent chemical properties and long service life (they have stable structure and excellent mechanical, physical and chemical properties under high-temperature operating conditions).

[0033] Furthermore, preferably as follows Figure 5 , Figure 6 and Figure 7 The prefabricated cavity floor slab high-temperature resistant structure shown also includes a first adhesive layer 10-1, a second adhesive layer 11-1, and a third adhesive layer 12-1, which are respectively coated on one side of the high-temperature resistant partition 10, the lower cover plate high-temperature resistant partition 11, and the upper cover plate high-temperature resistant partition 12.

[0034] Among them, the first adhesive layer 10-1, the second adhesive layer 11-1, and the third adhesive layer 12-1 include, but are not limited to, high-temperature resistant epoxy anchoring adhesive, so as to achieve stable and reliable installation of the high-temperature resistant partition 10, the high-temperature resistant partition 11 of the lower cover plate, and the high-temperature resistant partition 12 of the upper cover plate on the middle hollow box 100, the lower cover plate 101, and the upper cover plate 102, respectively, which makes the construction assembly and installation convenient and efficient.

[0035] The prefabricated hollow floor slab high-temperature resistant structure of this product is assembled with the following layers applied during assembly: the high-temperature resistant partition 10, the lower cover plate high-temperature resistant partition 11, the upper cover plate high-temperature resistant partition 12, and the intermediate hollow box 100, lower cover plate 101, and upper cover plate 102 are all coated with the first adhesive layer 10-1, the second adhesive layer 11-1, and the third adhesive layer 12-1, respectively; and the abutting surfaces of the high-temperature resistant partition 10, the lower cover plate high-temperature resistant partition 11, and the upper cover plate high-temperature resistant partition 12 are also coated with the first adhesive layer 10-1, the second adhesive layer 11-1, and the third adhesive layer 12-1, respectively. This achieves the corresponding sealing and prevents high-temperature flue gas from entering the intermediate hollow box 100, lower cover plate 101, and upper cover plate 102 through gaps (gap between the abutting surfaces of the high-temperature resistant partition 10, the lower cover plate high-temperature resistant partition 11, and the upper cover plate high-temperature resistant partition 12).

[0036] This prefabricated hollow floor slab features a high-temperature resistant structure that effectively protects the prefabricated hollow floor slab (with smoke exhaust function) from smoke.
