Description

Technical Field

[0001] The invention relates to a structural system, in particular to a wall, floor and roof structural system of an assembled kitchen and bathroom. Background Art

[0002] The installation of traditional prefabricated kitchen and bathroom wall decoration requires leveling the wall concrete and then paving it with wet concrete method. The installation process is complicated, there is a lot of construction waste, and the large slabs of ceramic tiles or rock slabs are easy to fall off the wall after paving, which is costly. The pipeline systems such as water supply and drainage pipelines, electrical pipelines, etc. need to be grooved and installed in the structural wall. The structural wall needs to be waterproofed before the decorative surface layer can be paved. Screws are needed to fix the roof and top plate on the top. The installation process is complicated, the installation accuracy is low, there is a lot of construction waste, the installation efficiency is low, and the cost is high. Summary of the invention

[0003] The present invention aims to overcome the defects of the prior art and provide a prefabricated kitchen and bathroom wall, floor and ceiling structure system for use in buildings, where the pipeline system does not need to be pre-buried in the structural wall, the structural wall does not need waterproofing construction, and the wall decorative surface layer is installed without concrete wet work. The top plate can be connected to the roof and the top plate without screws, and dry work is adopted, with less construction waste, simple installation process, high installation precision, high installation efficiency and low construction cost.

[0004] The wall, floor and roof structural system of the assembled kitchen and bathroom described in the present invention includes a structural floor, a wall leveling support, a wall leveling keel, a wall keel, a wall panel, a structural wall, a roof keel, a roof, a structural roof, and a pipeline system; the wall leveling support is above the structural floor, the bottom of the wall panel is placed on the wall leveling support, and the top surface of the wall leveling support at the bottom of each row of wall panels is close to the same horizontal plane; at least two horizontal wall leveling keels are fixed on the same structural wall on the back of the same row of wall panels, and the overlapping surface with the wall keel is close to the same plane; the wall keel includes a flat keel; the sides of two wall panels adjacent to each other in the plane are provided with keel slots , the keel slot is connected by a plug of the flat keel; there is a waterproof overlap on the wall keel, the width of which exceeds the joint edge of two adjacent wall panels by more than 10mm, and there is a screw fixing groove on the waterproof overlap, and the fixing screw fixes the wall leveling keel in the screw fixing groove; there is a top plate keel on the top of the wall panel, there is a wall panel sleeve groove on the top plate keel, the top of the wall panel is sleeved in the wall panel sleeve groove, there is a top plate placement strip with a width of 5mm-50mm on the top plate keel, a top plate is fixed on the top plate placement strip, at least one top plate connecting two opposite top plate keels is an integral plate without an overall break in the middle, and the top plate is below the structural top plate; the pipeline system is laid on the structural wall and the back of the wall panel.

[0005] When applied to buildings, first fix the wall leveling keel on the structural wall. There should be no less than 2 fixed structural walls behind each row of wall panels, and the best is one every 600mm or so. The facade of the leveling keel is close to the same plane, and the best is the same plane. The leveling keel on the same wall can be a continuous whole strip, or a small section or point, and the best is a continuous whole strip. Then extend the wall leveling support to the bottom of the facade of the leveling keel and the ground of the structural floor. When fixing, adjust the wall leveling support at the bottom of each row of wall panels to be close to the same horizontal plane. The closer to the horizontal plane, the better. The wall leveling support can be a long strip that can support multiple rows of wall panels, or it can be a long strip that can support multiple rows of wall panels. Block or point shape, preferably long strip shape. At the same time, it is necessary to ensure that the top surface of the wall leveling support can support the bottom of the wall panel, and then install the pipeline system along the wall. The pipeline includes water supply and drainage pipelines and electrical pipelines. Then, put the bottom of the wall panel on the upper surface of the wall leveling support. On the same plane, first insert the plug at one end of the flat keel into the keel slot on the side of the wall panel. After tightening, fix the wall leveling keel longitudinally from the screw fixing groove of the flat keel, and then insert the keel slot of another row of wall panels into the plug at the other end of the fixed flat keel. The same wall is installed in sequence. Since the top surface of the wall leveling support at the bottom of each row of wall panels is close to the same The horizontal plane (due to measurement tools and installation errors, it is generally impossible to achieve absolute horizontality, but the closer to horizontality the better), so the wall panels placed on the wall leveling support are also close to the same horizontal plane. When there are multiple wall panels in the same row and there are upper and lower joints, it prevents the wall from tilting and causing uneven joints of the wall panels. At the same time, it also prevents the same wall from tilting at the end. The wall panels need to increase the installation space and occupy the plane space of the building. The point-shaped ground leveling of the wall leveling support is used to replace the traditional floor concrete wet surface leveling, which can increase the leveling accuracy while simplifying the process, improving the installation efficiency and reducing the generation of construction waste. In addition, because the same row is composed of multiple wall panels with upper and lower joints, it prevents the wall from tilting and causing uneven joints of the wall panels. At the same time, it also prevents the same wall from tilting at the end. The wall panels need to increase the installation space and occupy the plane space of the building. The point-shaped ground leveling of the wall leveling support is used to replace the traditional floor concrete wet surface leveling, which can increase the leveling accuracy while simplifying the process, improving the installation efficiency and reducing the generation of construction waste. At least two horizontal wall leveling keels are fixed on the same structural wall on the back of the wall panel, and the overlapped surface with the wall keel is close to the same plane. Therefore, after the wall keel is connected to the wall panel, as long as the wall keel is fixed to the wall leveling keel, the fixed wall panel is close to the same plane. With the same wall leveling keel, only a few points are fixed on the structural wall, and the leveling of the entire leveling keel can be achieved by adjusting a few fixing points, thereby achieving the leveling of the front wall panel fixed on the leveling keel, thereby changing the traditional process of concrete surface leveling of the structural wall, making the wall panel installation process simple, fast, and no redundant construction waste is generated;The pipeline system is laid between the wall panel and the structural wall. As a result, the traditional installation of water supply and drainage, electrical pipelines, which requires grooving and burying in the structural wall, is eliminated. The pipelines are not buried and fixed. The pipeline holes in the wall (such as holes for shower heads, angle valves, washbasin drainage, switch boxes, etc.) have been opened in the factory. When there is a deviation from the position of the pipeline, the pipeline can be moved to the required position, and then the wall polyurethane foam is injected into the pipeline holes of the wall panel (it is also possible to install waterproof wall panels while injecting from the area of ​​the wall panels that have not yet been installed into the gap between the installed wall panels and the structural wall panels). After the polyurethane foam is cured, it will wrap and fix the pipeline system. As a result, all wall panels and connected parts can be produced in the factory, assembled on site, and installed. No need to drill holes or do wet concrete work, which simplifies the process, improves work efficiency, and reduces the professional requirements of installers. The wall panels are connected by plugs connected to the keel slots, the wall keels and the wall leveling keels, and the wall leveling keels and the structural walls, which can form a firm fixation method between the wall panels and the structural walls to prevent the wall panels from falling off. At the same time, the concave and convex riveting structure of the plug and the keel slot is combined with the waterproof overlap structure on the wall keel with a width of more than 10mm exceeding the joint edge of the two adjacent wall panels, forming a wall waterproof structure. When the wall panel joints are not sealed with sealant, the wall panel joints will not leak, thereby realizing that the structural wall does not require waterproof construction. Further, when the wall polyurethane foam is filled between the back of the wall panel and the structural wall, The polyurethane foam on the wall expands under the constraint of the connection structure between the wall panel and the structural wall, and can wrap the joint between the waterproof overlap of the wall keel and the back of the wall panel without causing deformation of the wall surface, thereby further increasing the waterproof performance of the wall surface. Filling the joint of two adjacent waterproof wall panels with sealant also further increases the waterproof performance of the wall surface. The top of the wall panel is sleeved in the wall panel sleeve groove. The wall panel sleeve groove can correct the wall panels of different columns while realizing the rapid installation of the top plate keel. There is a top plate placement strip on the top plate keel, and the top plate placement strip is fixed with the top plate structure. After the top plate 7 fixes the top plate placement strip, a frame can be formed to prevent the wall panel from sinking inward or falling outward. At the same time, the width of the top plate placement strip is between 5mm-50mm, which can form fault tolerance for wall panel installation. Mechanism, reduce the requirements for wall panel installation accuracy, even if there is a partial deviation, the top plate placement strip can compensate for the deviation, hide the top plate outside, reduce installation difficulty, improve work efficiency, and the top plate is fixed to the top plate placement strip of the top plate keel, the top plate keel is fixed to the top of the wall panel, at least one top plate connecting the two opposite top plate keels is an integral plate without a break in the middle, to prevent the top plate from failing to support and resist tension when the top of the wall panel tilts inside and outside, thereby forming a relationship of mutual fixation, mutual pulling, and mutual compression, which can increase the strength of the top plate, thereby fixing the top plate without bolts to connect the top plate to the top of the structural wall (when a heavier bathroom heater is installed on the top plate, the frame of the bathroom heater can be fixed to the top of the structural wall with bolts), which can increase the building height and space utilization. ;

[0006] Furthermore, the tops of the corners of two adjacent top plate keels are fixed with corner fixing parts; the corner fixing parts have corner sleeve grooves that are right-angled downwards, and the tops of the ends of the two adjacent top plate keels are all sleeved in the corner sleeve grooves for fixation. With this structure, the corner sleeve grooves can form a sleeve mold, and the tops of the ends of the two adjacent top plate keels are all sleeved in the corner sleeve grooves for fixation, forming a quick installation, quick adjustment and fixation of the joints of the two adjacent top plate keels.

[0007] Furthermore, the top of the ceiling keel and the wall keel are transversely fixed by ceiling screws. This structure can transversely fix the ceiling keel and the wall keel from the space in the bathroom and kitchen, thereby increasing the space utilization of the building height.

[0008] Furthermore, the wall keel also includes an internal corner keel, and two adjacent wall panels at the internal corner are connected by the internal corner keel. One side of the internal corner keel is provided with an expansion groove, and the groove depth of the expansion groove is not less than 3mm. The expansion groove with a certain depth can form a fault-tolerant compensation structure to prevent the wall panel production deviation or the process difference of the installer from causing the wall panel to be unable to be installed. The other side is provided with a internal corner clamp, and the side of one wall panel is inserted in the expansion groove, and the other wall panel has a keel slot inserted in the internal corner clamp; the two adjacent waterproof wall panels are inserted in the structure of the internal corner keel to form a waterproof structure of the adjacent wall panel joints to prevent water leakage in the wall panel joints at the internal corner. The joints are filled with sealant and the gap between the wall panel and the structural wall is filled with wall polyurethane foam to improve the waterproof performance of the wall, and the process of waterproof construction of the walls of traditional bathrooms and kitchens can be eliminated.

[0009] Furthermore, the wall keels also include external corner keels, which connect two wall panels on different surfaces at the external corners. The width of the waterproof overlap of the external corner keel exceeds the joint edge of the two adjacent wall panels by more than 5 mm. There are screw fixing grooves on the waterproof overlap. The waterproof overlap can prevent water seepage into the gaps between the wall panels from flowing out of the external corner keels. The screw fixing grooves ensure that the screw heads will not affect the installation of the wall panels, and can also play a role in diverting water seepage.

[0010] Furthermore, the thickness from the wall panel surface outside the pipe well area to the structural wall surface is between 10mm-60mm, generally around 35mm-40mm, thereby improving the utilization of the building plane space. BRIEF DESCRIPTION OF THE DRAWINGS
