Abstract
Description
Technical Field
[0001] This utility model relates to the field of interior decoration and renovation technology, and in particular to a bathroom chassis device. Background Technology
[0002] While bathroom chassis obtained by stamping or extruding polymers (such as plastics) have the advantages of being lightweight and low-cost (for mass production), they also have the following drawbacks: 1. When in use, the bathroom chassis provides a strong sense of instability, resulting in a poor user experience.
[0003] 2. Bathroom bases need to be manufactured using molds. The shape of the bathroom base is limited by the mold, which means that if the bathroom base has a variety of sizes, more types of molds need to be prepared, which will increase the manufacturing cost for small-batch production. Summary of the Invention
[0004] In view of the above-mentioned technical problems existing in the prior art, the present invention provides a bathroom chassis device.
[0005] To solve the above-mentioned technical problems, the technical solution adopted in the embodiments of this utility model is as follows: A bathroom chassis assembly includes at least one chassis unit, the chassis unit comprising: a chassis body and a floor layer disposed on the chassis body; wherein: The chassis body includes a chassis body and an outer edge spliced around the side of the chassis body; The outer surface of the chassis body is wetted or coated to obtain a sealing layer, and the ground layer is placed on the chassis body covered with the sealing layer.
[0006] Preferably, the bathroom chassis assembly comprises two chassis units, which overlap at adjacent sides; wherein: The ground floor of one chassis unit is designated as the wet zone, while the ground floor of the other chassis unit is designated as the dry zone.
[0007] Preferably, The outer edge and the chassis body are made of composite board, and the outer edge and the side end face of the chassis body are fixed by screws or by adhesive.
[0008] Preferably, the two chassis units have stepped structures on the sides of their chassis bodies, and the two stepped structures overlap.
[0009] Preferably, a sealing strip is provided between the stepped surfaces where the two chassis bodies overlap.
[0010] Preferably, a water channel is provided near the edge of the ground layer serving as the wet area, and the bottom of the water channel is provided with an inclined slope so that the water channel has a low-level area, and a floor drain hole is provided in the low-level area.
[0011] Preferably, the ground layer is made of rock slabs or floor tiles cut from stone.
[0012] Compared with the prior art, the beneficial effects of the bathroom chassis device disclosed in this utility model are: 1. After the basic structure of the chassis body is formed by splicing, a sealing layer is covered on the surface of the chassis body to prevent water from seeping from the bottom of the chassis body. This makes the spliced chassis body have good waterproof performance while having good resistance to trampling.
[0013] 2. The basic structure of the chassis body obtained by splicing can meet the requirements of various sizes.
[0014] 3. The chassis unit is configured as a split structure, which facilitates the transport of the chassis unit to narrow areas of the bathroom and makes assembly easier.

[0023] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.
[0024] like Figure 1 and 2 As shown, an embodiment of this utility model discloses a bathroom chassis device. The bathroom chassis device is a split structure, that is, the bathroom chassis device includes two chassis units 10. The two chassis units 10 are manufactured in a prefabrication factory. At the construction site, the two chassis units 10 are transported to the bathroom structural floor via the bathroom door frame and assembled on the bathroom structural floor. One chassis unit 10 is laid in the wet area and the other chassis unit 10 is laid in the dry area.
[0025] The bathroom chassis unit 10 includes a chassis body 20 and a floor layer 30. The chassis body 20 includes a rectangular chassis main body 21 and a plurality of strip-shaped outer edges 22. In the prefabrication plant, the chassis main body 21 and the strip-shaped outer edges 22 are cut from a composite board (such as a composite board with an extruded board middle layer and a cement-bonded surface) according to size requirements, such that the outer edges 22 are arranged around the chassis main body 21. Then, fasteners such as countersunk screws 23 are used to pass through the outer edges 22 and the end faces of the side of the chassis main body 21 from the outside of the outer edges 22 to fix the outer edges 22 to the chassis main body 21, thereby forming a recessed cavity with the outer edges 22 and the chassis main body 21. After fixing the outer edge 22 to the chassis body 21 to form the basic structure of the chassis body 20, a sealing layer 40 is applied to the outer surface of the chassis body 20 by immersing the entire chassis body 20 or by coating the outer side. This prevents water penetration of the entire chassis body 21, especially preventing water penetration through the joint between the outer edge 22 and the chassis body 21. Preferably, after cutting the chassis body 21, a stepped structure 211 is cut out on one side of the chassis body 21.
[0026] The ground layer 30 is placed within the cavity formed by the chassis body 21 and the outer edge 22, and is used for user walking. A water channel 31 is machined onto the surface of the ground layer 30 of the chassis unit 10 corresponding to the wet area. The water channel 31 extends around the edge of the ground layer 30, and the bottom of the water channel 31 is machined with a slope to guide water from the ground layer 30. A drain hole 32 is disposed in the lower area of the water channel 31 for drainage. The ground layer 30 may include floor tiles or slabs.
[0027] At the construction site, the stepped structures 211 of the two chassis units 10 are overlapped. Before overlapping, adhesive is applied to the surface of the stepped structure 211 and / or a sealing strip is placed to prevent water from seeping through the overlap gap.
[0028] The bathroom chassis device disclosed in this utility model has at least the following advantages: 1. After the basic structure of the chassis body 20 is formed by splicing, a sealing layer 40 is covered on the surface of the chassis body 20 to prevent water from seeping from the bottom of the chassis body 20, so that the chassis body 20 formed by splicing has good waterproof performance while having good resistance to trampling.
[0029] 2. The basic structure of the chassis body 20 obtained by splicing can meet the requirements of various sizes.
[0030] 3. The chassis assembly is configured as a split structure, which facilitates the transport of the chassis unit 10 to narrow areas of the bathroom and makes assembly easier.
