Description

Technical Field

[0001] The utility model 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. This makes the installation process complicated, produces a lot of construction waste, and large tiles or rock slabs are prone to falling off the wall after being laid, which is costly. Drainage pipelines, electrical pipelines and other pipeline systems need to be grooved and installed in the structural wall. The structural wall needs to be waterproofed before the decorative surface layer can be laid. Screws are needed to fix the roof and top plate on the top, which makes the installation process complicated, with low installation accuracy, a lot of construction waste, low installation efficiency and high cost. Summary of the Invention

[0003] The utility model 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, which does not require pre-buried pipeline systems in the structural wall surface, does not require waterproofing of the structural wall surface, and does not require wet concrete operation for the installation of the wall decorative surface layer. The top plate can be connected to the roof and the top plate without screws, adopts dry operation, has less construction waste, is simple in installation process, has high installation precision, high installation efficiency and low construction cost.

[0004] The wall, floor and roof structure 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 upper and lower sides of the same structural wall on the back of the same row of wall panels, and the overlapping surfaces with the wall keels are close to the same plane; the wall keels include flat keels; the sides of two wall panels adjacent to each other in the plane are provided with keel plugs The wall keel is provided with a waterproof lap edge with a width exceeding 10mm of the joint edge of the two adjacent wall panels, and the waterproof lap edge is provided with a screw fixing groove, and the fixing screw fixes the wall leveling keel in the screw fixing groove; the top of the wall panel is provided with a top plate keel, and the top plate keel has a wall panel sleeve groove, the top of the wall panel is sleeved in the wall panel sleeve groove, and the top plate keel has a top plate placement strip with a width of 5mm-50mm, and a top plate is fixed on the top plate placement strip, and at least one top plate connecting the 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 used in buildings, first fix the structural wall with the wall leveling keel. Fix at least 2 leveling keels on the structural wall behind each column of wall panels, preferably one every 600mm or so, and the facade of the leveling keel is close to the same plane. The leveling keel on the same wall can be a continuous whole line, or a small section or point. The best is a continuous whole line. 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 column 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 columns of wall panels, or it can be a long strip that can support multiple columns 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, electrical pipelines, and 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 through the screw fixing slot 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 the horizontal 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 installation space needs to be increased and the plane space of the building is occupied. The use of several point-shaped ground leveling of the wall leveling support instead of the traditional ground concrete wet surface leveling can increase the accuracy of leveling while simplifying the process, improving installation efficiency and reducing the generation of construction waste. In addition, due to the same row, At least two horizontal wall leveling keels are fixed on the same structural wall on the back of the wall panel, and the overlapping surfaces with the wall keels are close to the same plane. Therefore, when the wall keel is connected to the wall panel, as long as the wall keel and the wall leveling keel are fixed, the fixed wall panel is close to the same plane. The same wall leveling keel only needs to be fixed to the structural wall at a few points, 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. This changes the traditional process of concrete surface leveling of structural walls, making the wall panel installation process simple and fast, and no unnecessary construction waste is generated;The pipeline system is laid between the wall panels and the structural wall. As a result, there is no need for the traditional installation of water supply and drainage, and electrical pipelines that require grooving and burying in the structural wall. The pipelines are not buried and fixed. The pipeline holes in the wall (such as holes for shower heads, angle valves, washbasin drains, 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 from the pipeline holes of the wall panel (it can also be injected from the area of the wall panel that has not been installed to the gap between the installed wall panel and the structural wall panel while installing the waterproof wall panel). 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 and assembled and installed on site. 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 to the keel slots, the wall keels to the wall leveling keels, and the wall leveling keels to the structural wall, which can form a firm fixation between the wall panels and the structural wall to prevent the wall panels from falling off. At the same time, the concave and convex riveted structure of the plugs and the keel slots 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 to form 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, which can wrap the joints 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 joints between 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 and 50mm, which can form fault tolerance for wall panel installation. The mechanism reduces the requirements for wall panel installation precision. Even if there are some deviations, the top panel placement strips can compensate for the deviations, hiding the top panel from the outside, reducing installation difficulty and improving work efficiency. The top panel is fixed to the top panel placement strips of the top panel keels. The top panel keels are fixed to the top of the wall panel. At least one top panel connecting two opposing top panel keels is a single, unbroken panel in the middle. This prevents the top panel from losing its support and tensile strength when the top of the wall panel tilts inward or outward. This creates a mutually fixed, pulling, and compressive relationship, which increases the strength of the top panel. This fixation of the top panel does not require bolts to connect the top panel to the top of the structural wall (when a heavy bathroom heater is installed on the top panel, the heater frame can be bolted to the top of the structural wall), which can increase building height and utilize space.

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

[0007] Furthermore, the top of the roof keel and the wall keel are fixed horizontally by roof screws. This structure can fix the roof keel and the wall keel horizontally 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. The 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. The 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, which causes the wall panel to be unable to be installed. The other side is provided with a internal corner clamp. The side of one wall panel is inserted into the expansion groove, and the other wall panel has a keel slot inserted into the internal corner clamp; the two adjacent waterproof wall panels are inserted into 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. Combined with the structure of filling the joints with sealant and filling the gap between the wall panel and the structural wall with polyurethane foam on the wall, the waterproof performance of the wall is improved, and the traditional waterproof construction process of the walls of the bathroom and kitchen 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 5mm. 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 keel. 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
