[0014] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0015] The following will be combined with the drawings in the embodiments of the invention to clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of the embodiments. Based on the embodiments of the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention.

[0016] Example 1 like Figure 1-7 As shown, a spliced ​​barrier-free waterproof chassis includes multiple supporting frames. In this embodiment, there are two supporting frames. The spliced ​​barrier-free waterproof chassis is spliced ​​by two supporting frames and can reach a size of 3600mm*4000mm, so it is suitable for use in hospitals, apartments, schools, residential buildings, public toilets in public buildings, hotels, villas and other toilets. It has a wide range of applications. When the size is larger, a supporting frame can be installed at the lower end of the spliced ​​barrier-free waterproof chassis to improve the stability of use.

[0017] The supporting frame includes a frame profile 1. In some usage scenarios, the bathroom is integrally installed with a spliced ​​barrier-free waterproof chassis and side wall panels. The frame profile 1 cooperates with the side wall panels and is supported at the lower end of the side wall panels. The specific frame profile 1 can be used as a bottom support beam of the side wall panels, or can be integrally formed with the bottom support beam of the side wall panels. In other usage scenarios, a pit is partially reserved in the bathroom, and a spliced ​​barrier-free waterproof chassis is installed. The frame profile 1 cooperates with the side wall of the pit. In this embodiment, a spliced ​​barrier-free waterproof chassis is integrally installed in the bathroom. The frame profile 1 includes an upwardly extending waterproof edge 101. The height of the frame profile 1 is 30mm-60mm, so as to achieve a better effect of preventing water overflow. In addition, the waterproof edge 101 is sideways, which can improve the deformation resistance of the frame profile 1. The lower end of the waterproof edge 101 is a profile body 107, and the outer side of the profile body 107 forms an avoidance The opening 102 avoids the corner of the side wall so that the frame profile 1 can obtain a flat support area. A downward supporting edge 103 is provided at the lower end of the profile main body 107. The height of the supporting edge 103 is 5mm-6mm, which is relatively small and can better adapt to the ground. The lower end face of the profile main body 107 inside the supporting edge 103 forms a supporting plane, which can then cooperate with the leveled support frame. A horizontal support plate 104 is provided on the inner side surface of the lower end of the profile main body 107. The support plate 104 extends inwardly and is bent upward at the end to obtain a bend one. The bend one can improve the deformation resistance of the inner end of the support plate 104. A horizontal upper baffle 105 is provided on the inner side surface of the upper end of the profile main body 107. The upper baffle 105 extends inwardly and is bent upward at the end to obtain a bend two. A supporting platform 106 is formed on the upper end face of the profile main body 107. The lower end of the decorative wall panel of the side wall panel cooperates with the supporting platform 106 to facilitate positioning and installation.

[0018] The support frame includes a splicing profile 3 which is also used to connect two adjacent support frames. The frame profile 1 and the splicing profile 3 are both made of steel profiles or aluminum alloy profiles. The structural strength and corrosion resistance need to be ensured. In this embodiment, the splicing profile 3 includes a profile body 2 301. In order to lay the waterproof layer 4 and floor tiles, the upper end surface of the splicing profile 3 is not higher than the upper baffle 105, and the lower end surface is not lower than the supporting edge 103. The thickness of the splicing profile 3 is limited. Therefore, the profile body 2 301 is required to have a higher structural strength, which is achieved by increasing the profile wall thickness. There is a waterproof connection device between the two spliced ​​profiles 3, and the waterproof connection device includes a waterproof filling layer constructed at the gap between the two adjacent spliced ​​profiles 3. Specifically, the waterproof connection device includes a splicing structure integrally formed on the outer side of the profile body 2 301, and the splicing structure includes an expansion waterproof cavity 303. The side wall of the expansion waterproof cavity 303 is arc-shaped, and the waterproof filling layer includes an expansion waterproof material filled in the expansion waterproof cavity 303. The expansion waterproof material is selected from high-density polyurethane foam. The two expansion waterproof cavities 303 form a cavity with an elliptical cross section. The inside is filled with polyurethane foam glue, so that a cylindrical waterproof body that matches the side wall of the cavity can be quickly formed, and a support between the two splicing profiles 3 can be formed. A fixed waterproof cavity 304 is provided at the lower end of the expansion waterproof cavity 303. The side walls of the expansion waterproof cavity 303 and the fixed waterproof cavity 304 are processed with transverse waterproof convex ridges 305. The waterproof filling layer also includes a waterproof adhesive injected into the fixed waterproof cavity 304. Specifically, PUR hot melt adhesive can be selected, which can be quickly cured and has good weather resistance, so that the two splicing profiles 3 can be quickly connected. There is a connecting groove on the upper end surface of the connecting profile 3, and a connecting side plate that matches the connecting groove is bent on the side of the baffle plate 302, and the connecting side plate is inserted downward into the connecting groove. A waterproof adhesive layer is coated on the bottom of the baffle plate 302, and a positioning base 306 is installed between the lower end surfaces of the two spliced ​​profiles 3. A positioning groove that matches the positioning base 306 is integrally formed on the lower end surface of the spliced ​​profile 3, and the end of the positioning base 306 is bent and inserted into the positioning groove. A snap-in groove 307 that matches the waterproof filling body 5 is also integrally formed at the lower end of the inner side surface of the spliced ​​profile 3.

[0019] A waterproof filler 5 is installed in the support frame, and the support frame is connected to a first support device for supporting the waterproof filler 5. The first support device includes a support plate 104 at the lower end of the frame profile 1, and the support plate 104 supports the edge position of the waterproof filler 5. The first support device also includes a waterproof membrane layer 7 between the frame profile 1 and the end of the waterproof filler 5. Specifically, the waterproof filler 5 is a rigid polyurethane foamed, and a foamed mortar can also be selected. When using the foamed mortar, it is necessary to control the water flow during the construction process to avoid water accumulation in the gap. After the support frame is fixed, the rigid polyurethane is filled in the support frame, and the waterproof filler 5 is obtained after foaming. The waterproof filler 5 and the frame There is a smaller gap between the profile 1 and the spliced ​​profile 3, which leads to better waterproof performance. The end of the waterproof filling body 5 is supported and sealed by the support plate 104. Before filling with hard polyurethane, a waterproof adhesive is coated on the inner side of the frame profile 1 and the spliced ​​profile 3 to form a waterproof membrane layer 7, which is waterproof at the gap. A waterproof layer 4 is constructed on the upper surface of the waterproof filling body 5. In this embodiment, the waterproof layer 4 is an integral felt or membrane, which is redundantly laid to achieve a better waterproof effect. Because the felt or membrane itself has ductility, during use, a slight deformation of the spliced ​​barrier-free waterproof chassis will not cause leakage. The waterproof layer 4 extends to the lower side of the upper baffle 105 and curls, which can effectively improve the waterproof performance.

[0020] Mortar or adhesive is laid on the upper surface of the waterproof layer 4, and then the floor tile layer 2 is laid. When laying the floor tile layer 2, the gap between the floor tile layer 2 and the splicing profile 3 is misaligned. After laying is completed, the upper surface of the spliced ​​barrier-free waterproof chassis has no protrusions and is flat as a whole.

[0021] The spliced ​​barrier-free waterproof chassis provided in this embodiment can be installed by laying or by racking. The rack-mounted installation is specifically selected to facilitate the arrangement of pipelines under the spliced ​​barrier-free waterproof chassis. During the installation process, the frame profile 1 is the main load-bearing structure, and the support frame is connected to the second support device. The second support device includes a plurality of bases 13 distributed along the frame profile 1, and the spacing between two adjacent bases 13 is 400mm-500mm. The upper end of the base 13 is connected to a support plate 14 through an adjustable support column 12, and the support plate 14 is connected to the support plate 14. The supporting plane is matched, the supporting plate 14 is long and can support a longer length, the base 13 is disc-shaped, and the adjustable supporting column 12 includes a threaded sleeve connected to the supporting plate 14 and a screw connected to the base 13. The outer diameter of the screw is 40mm-50mm. The base 13 is made of PVC material, which has good weather resistance and large rotation resistance, and can ensure stability for long-term use. Place multiple bases 13 on the foundation, and then adjust the height to obtain a flat supporting platform, and can ensure stability for long-term use.

[0022] The frame profile 1 is supported by a second supporting device, and the waterproof filling body 5 is also connected to a third supporting device, which includes a base 20. The upper end of the base 20 is connected to a support plate 21 through a delayed telescopic device. The delayed telescopic device includes a support tube 15 fixed to the upper end of the base 20, and a floating shaft 16 is inserted in the support tube 15. The upper end of the floating shaft 16 is connected to the support plate 21. The support tube 15 is filled with mortar, and a mortar overflow hole 19 is processed at the lower end of the bottom side wall of the support tube 15. The waterproof filling body 5 presses the support plate 21 downward to make the mortar overflow from the mortar overflow hole 19. In this embodiment, the support tube 15 and the floating shaft 16 are both made of steel pipes, which have a high crack resistance effect. The outer diameter of the floating shaft 16 is The support plate 21 is disc-shaped with a diameter of 350-500mm, which can provide a larger support area. The average particle size of the aggregate in the mortar is 2-3mm, and the aperture of the mortar overflow hole 19 is 4-5mm. Since the mortar is viscous, under normal circumstances, the mortar will not overflow from the mortar overflow hole 19. The amount of mortar in the support tube 15 is controlled so that the stroke of the floating shaft 16 is compressed to 30-40mm. During the installation process, the spliced ​​barrier-free waterproof chassis is first mounted on the third support device, which can reserve more adjustment gaps, thereby facilitating the adjustment of the position, and then slowly press down to make the frame profile 1 cooperate with the second support device. Since the third support device is a spliced ​​barrier-free waterproof chassis The third supporting device is pushed down, and the third supporting device always cooperates with the waterproof filling body 5 to ensure the support stability. A graded overflow device is installed between the floating shaft 16 and the supporting tube 15. The graded overflow device includes an elastic shaft 17. The elastic shaft 17 is a spring or a rubber shaft. A multi-layer overflow orifice plate 18 is installed on the elastic shaft 17 from top to bottom. In this embodiment, there are two layers of overflow orifice plates 18, which are made of PVC material with a thickness of 8-10mm. The aperture of the overflow orifice plate 18 is 4-5mm, and the spacing between the two adjacent layers of overflow orifice plates 18 is 30mm. The graded overflow device extends upward into the floating shaft 16. In the process of the third supporting device being pushed down by the spliced ​​barrier-free waterproof chassis, the mortar overflows upward and pushes the elastic shaft 1 7 deformation, can increase the speed of descent of the spliced ​​barrier-free waterproof chassis, thereby increasing the installation speed. After the descent is completed, the elastic shaft 17 has a tendency to reset and deform, and slowly releases, thereby ensuring that the stress of the mortar is slowly released, and compensating for the loss caused by the overflow of the mortar overflow hole 19. Through the multi-layer overflow orifice plate 18, the resistance to the overflow upward can be gradually increased, thereby making the descent speed of the spliced ​​barrier-free waterproof chassis slow from fast to slow. In the process of the elastic shaft 17 resetting and deforming, the mortar is suppressed from overflowing upward, thereby ensuring that the mortar at the lower end of the support tube 15 is dense. In the process of testing, try to use polyurethane foam with high initial viscosity, which also has good stability after shaping, but the cost is relatively high and the shaping time is long.

[0023] The spliced ​​barrier-free waterproof chassis provided in the present embodiment can be constructed by constructing a waterproof filling body 5 in the supporting frame after the two supporting frames are manufactured, and then installed in the bathroom to lay a waterproof layer 4 and a floor tile layer 2, or it can be spliced ​​into a whole on a platform 8. When manufacturing the supporting frame, a splicing support device is used. The splicing support device includes a bottom plate 9 that matches the inner edge of the lower end of the frame profile 1, and a reinforcing layer 10 is installed at the edge of the bottom plate 9. A demoulding layer is coated on the upper surface of the bottom plate 9. Specifically, the bottom plate 9 is cut and formed by a wooden board or a high-density foam board, which is low in cost and light in weight. A steel plate is fixed on the edge of the bottom plate 9 to obtain the reinforcing layer 10, thereby improving the deformation resistance. Then, a water-based demoulding agent is coated on the upper surface of the bottom plate 9 to facilitate demoulding. The bottom plate 9 is fixed on the platform 8 by an adhesive, and then the cut frame profile 1 and the splicing profile 3 are placed on the platform 8. The inner side of the frame profile 1 is bonded to the reinforcing layer 10 by a pressing block, and a mold release layer is formed in the middle position of the bottom plate 9. The matching groove 11, the splicing profile 3 can be inserted downward into the groove 11, and the lower end of the inner wall of the splicing profile 3 is fitted with the inner wall of the groove 11. In order to ensure the fitting stability, a reinforcing layer 10 is also installed on the inner wall of the groove 11. It is worth noting that when the strength of the bottom plate 9 is sufficient, the reinforcing layer 10 can be omitted, and welding is performed to obtain a support frame. The support frame is filled with hard polyurethane, and then the upper template is installed on the upper surface of the hard polyurethane. The lower surface of the upper template is also coated with a water-based release agent, and foaming is performed to obtain a waterproof filling layer. A groove 11 is formed in the middle position of the bottom plate 9, so that two support frames can be processed at the same time, and a waterproof filling layer is made. When processing two support frames at the same time, the positioning base 306 is first placed in the groove 11. During use, the bottom plate 9 can be removed, or the bottom plate 9 can be used as a part of a spliced ​​barrier-free waterproof chassis, and then in cooperation with the third supporting device, the bottom plate 9 can extend upward into the cavity surrounded by the frame profile 1, thereby controlling the thickness of the waterproof filling body 5.

[0024] The spliced ​​barrier-free waterproof chassis provided in this embodiment can be manufactured on-site, or it can be transported to the site for installation after being manufactured in a center.

[0025] A butt joint gap 6 is formed at the butt joint of the two frame profiles 1. The butt joint gap 6 is waterproofed by a waterproof adhesive and a waterproof paint is applied on the surface. To ensure the structural strength, a reinforcing connector is also installed on the outside of the butt joint gap. The reinforcing connector can be a reinforcing rib plate (not shown in the figure). The reinforcing rib plate is fitted with the outer wall of the frame profile 1 and fixed to the frame profile 1 by welding or riveting. Sealant is applied at the corresponding position of the reinforcing rib plate and the butt joint gap 6. The reinforcing connector can also be a sealing sheet 108 inserted between the two frame profiles 1, such as Figure 8As shown, the sealing sheet 108 is a vulcanized rubber sheet with greater hardness. The vulcanized rubber sheet is pressed tightly against the end of the frame profile. A plug 109 that cooperates with the end of the frame profile 1 is integrally formed on the vulcanized rubber sheet. The plug 109 is inserted into the end of the frame profile 1, thereby forming a stable connection between the two frame profiles. The surfaces of the plug 109 and the vulcanized rubber sheet are coated with sealant to enhance the waterproof effect.
