Description

Technical Field

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

[0002] The installation of the traditional structural system of prefabricated kitchens and bathrooms generally requires that the walls of the prefabricated bathrooms be installed before the outer walls can be built. The ground needs to be elevated, water supply and drainage pipes need to be installed at the bottom of the chassis, and the top surface needs to be fixed from above the top plate. Therefore, a large installation working space is required, and the installed prefabricated bathroom occupies a large building space. When the wall panel material is made of ceramic or marble, there are many wall joints, and the joints are mostly waterproofed by filling and sealing, which is prone to leakage, and the installation speed is slow and the accuracy is low. Summary of the invention

[0003] The present invention aims to overcome the defects of the prior art and provide a prefabricated kitchen and bathroom structural system for use in buildings, which can make the ground not need to be elevated (it can also be elevated), and can install the prefabricated bathroom after the structural walls, ground and ceiling are installed. The installation operation space is small, the building space occupied is small, it is not easy to leak, the installation accuracy is high, and the installation speed is fast.

[0004] The assembled kitchen and bathroom structural system described in the present invention includes a structural floor, a chassis, a wall keel, a wall panel, a structural wall, a roof keel, a roof panel, and a structural roof panel; the chassis is above the structural floor; the chassis is provided with a waterproof flange, a water-facing surface and a door sill; the waterproof flange outside the door sill is higher than the water-facing surface; the wall keel includes a internal angle keel and a flat keel; the sides of two adjacent wall panels in the plane are provided with keel slots, and the keel slots are connected by plugs of the flat keel; two wall panels adjacent to the internal angle are connected by the internal angle keel, one side of the internal angle keel is provided with a telescopic groove, the groove depth of the telescopic groove is not less than 3mm, and the other side is provided with a internal angle clamp, the side of one wall panel is inserted in the telescopic groove, and the keel slot of the other wall panel is inserted in the internal angle clamp; the bottom of the wall keel and the bottom of the wall panel are both on the inner side of the waterproof flange and lower than the top of the waterproof flange; the back of the wall panel is provided with a leveling fixation. The flat keel is fixedly connected with the leveling; the top of the wall panel is provided with a top plate keel, the top plate keel is provided with a top plate placement strip, and the top plate is fixed on the top plate placement strip; the structural wall surface is on the outside of the waterproof flange of the chassis, and the top plate is below the structural top plate.

[0005] When the assembled kitchen and bathroom structural system is applied to a building, after the bottom of the chassis on which the wall panels are placed is leveled, the chassis is placed above the structural floor, and then the bottom of the wall keel is fixed to the inner side of the chassis waterproof flange, and the bottom of the wall panel falls on the bottom fixing of the wall panel of the chassis. The keel slots of two adjacent wall panels on the same plane are connected by the plug sleeve of the flat keel to form a waterproof structure with concave and convex riveting to prevent water leakage in the wall joints. The flat keel is connected to the leveling fixing that fixes the back of the wall panel to the structural wall surface. The leveling fixing has a front and rear leveling function before fixing the flat keel, so that the wall panels sleeved on the flat keel are in the same plane after installation; when the wall panel is installed to the turning point of the inner corner, it can be Insert the expansion slot on one side of the internal angle keel into one side of the wall panel. The depth of the expansion slot is less than 3mm. The depth of the expansion slot inserted into the side of the wall panel can be adjusted to compensate for the difference in processing and production accuracy between the chassis and the wall panel and the difference in professionalism of the installers, thereby reducing costs, reducing installation difficulty, and improving work efficiency; insert the keel slot of the wall panel into the internal angle clamp on the other side of the internal angle keel, thereby realizing a waterproof connection structure between the internal angle keel and the wall panel to prevent water leakage at the wall panel joint at the internal corner; in addition, the internal angle keel can be fixed with leveling or not; the structure of the flat keel, the internal angle keel and the wall panel and the leveling fixation can firmly fix the wall panel and the structural wall surface, so that the wall surface will not deform and fall over; then Finally, fix the top plate keel to the top of the wall panel, and then fix the top plate to the top plate keel, thereby forming the wall, floor and roof structure of the assembled toilet; among them, because the bottom plate waterproof flange outside the door sill surrounds and is higher than the water-facing surface, the bottom of the wall keel and the bottom of the wall panel are lower than the top of the waterproof flange, there is a threshold stone at the door sill, the threshold stone is higher than the water-facing surface, and there is a drainage slope on the water-facing surface, sloping towards the floor drain outlet, thus, the bottom plate and the waterproof flange form a basin-shaped structure, and the gathered scattered water on the wall panel surface will only flow from the bottom of the wall panel to the water-facing surface of the bottom plate inside the waterproof flange along this wall panel surface, and be discharged from the floor drain on the water-facing surface (when the bottom plate has a floor drain, the kitchen bottom plate may not have a floor drain); Before the joints of the panels are sealed with beautiful seams, a very small amount of water seepage may seep along the structure of the wall keels and wall panels to the back of the wall panels. The bottom of the wall keels and the bottom of the wall panels are both on the inside of the waterproof flange and lower than the structure of the top of the waterproof flange, which can form a fault-tolerant mechanism to prevent water seepage from flowing outside the waterproof flange and flowing along the outside of the flange to the structural floor, thereby preventing wall leakage. A top plate keel is fixed on the top of the wall panel, and the top plate placement strip of the top plate keel is fixed to the top plate. Therefore, there is no need to drill holes on the structural top plate to fix the hanger bolts and hanger keels to fix the top plate, which can reduce the distance between the top plate and the structural top plate, improve the utilization rate of the building height space, and at the same time, the construction process is simple, which can improve work efficiency.

[0006] Furthermore, the inner side of the waterproof flange of the chassis is fixed with a wall panel bottom, and the bottom of the wall panel falls on the wall panel bottom; the tops of the corners of two adjacent top plate keels are fixed with corner fixings; the corner fixings have corner sleeves that are right-angled downward, and the tops of the ends of the two adjacent top plate keels are all sleeved in the corner sleeves and fixed; the top plate keel is fixed to the top of the wall keel, and when the chassis and the structural floor are leveled and fixed, the inner side of the waterproof flange is vertical to the horizontal plane, and the bottom of the wall panel is fixed to the top of the chassis at the top of the lap leveling pad, as long as the bottom back of the wall keel is fixed against the inner side of the waterproof flange, the bottom of the wall panel is inserted into the wall panel bottom fixing, and the top of the wall panel is fixed on the top plate keel, the chassis can be quickly leveled and the wall panel can be quickly installed. Since the wall keel is fixed to the inner side of the waterproof flange, at the bottom After the plate is leveled, the inner side of the waterproof flange can automatically adjust the verticality of the lower part of the wall keel, and the verticality of the upper part of the keel can be adjusted by adjusting the leveling fixation. The bottom fixation of the wall panel not only fixes the wall panel, but also automatically adjusts the verticality of the lower part of the wall panel, reducing the leveling of the wall panel and wall keel installation, and realizing fast and accurate installation; and the tops of the corners of the two adjacent top plate keels are fixed with corner fixings; the corner fixings have a corner sleeve groove at a right angle downward, and the tops of the ends of the two adjacent top plate keels are both sleeved in the corner sleeve groove for fixation. When installing the top plate keel, just insert the end of the top plate keel into the right-angled corner sleeve groove. As long as it is inserted tightly, the right angle of the corner will automatically correct the two adjacent top plate keels into place, and there is no need to further adjust the two intersecting top plate keels, so as to achieve the purpose of fast and accurate installation and adjustment of the top plate keel. The top plate keel is transversely fixed to the wall keel by top plate screws; there is ample space for screwing on the inner side of the top plate keel, which is easy to install. At the same time, there is no need to reserve fixing space from the top to the bottom, which can increase the building height and utilize the space.

[0007] Furthermore, when the inner side of the waterproof flange is fixed with the wall panel bottom, the bottom of the wall panel falls on the wall panel bottom, the top plate keel is fixed to the top of the wall keel, and when the chassis and the structural floor are leveled and fixed, the inner side of the waterproof flange is vertical to the horizontal plane, and the bottom of the wall panel bottom is parallel to the bottom of the chassis at the top of the overlapped leveling pad, as long as the back of the bottom of the wall keel is fixed against the inner side of the waterproof flange, the bottom of the wall panel is inserted into the wall panel bottom, and the top of the wall panel is fixed on the top plate keel, the chassis can be quickly leveled and the wall panel can be quickly installed; because the wall keel is fixed to the inner side of the waterproof flange, after the chassis is leveled, the inner side of the waterproof flange can automatically adjust the verticality of the lower part of the wall keel, and the wall panel bottom fixation can not only fix the wall panel, but also automatically adjust the verticality of the lower part of the wall panel, thereby reducing the leveling of the wall panel and wall keel installation and realizing fast and accurate installation.

[0008] Furthermore, when the width of the waterproof overlap of the wall keel at the joint of two adjacent wall panels at different corners of the chassis flange exceeds the edge of the joint of the two adjacent wall panels by more than 5 mm, it can prevent water seepage from the wall panel from flowing from the extension of the waterproof overlap to the outside of the waterproof flange and to the ground of the structural floor; and there is a screw fixing groove on the waterproof overlap, and screws are used on the inner side below the top plate of the waterproof flange to fix the wall keel and the waterproof flange in the screw fixing groove, which can quickly correct the verticality of the wall keel and install the wall keel.

[0009] Furthermore, a wall panel sleeve groove is provided on the top plate keel, and the top of the wall panel is sleeved in the wall panel sleeve groove. The wall panel sleeve groove of this structure can correct the flatness of the wall panel and realize quick installation and quick adjustment at the same time.

[0010] Furthermore, the bottom of the wall panel is fixed as a sleeve groove with an opening facing upward, and the bottom of the wall panel is sleeved in the sleeve groove. The sleeve groove with an opening facing upward can correct the flatness of the bottom of the wall panel and facilitate the fixing of the bottom of the wall panel. The leveling fixation is a strip-shaped horizontally fixed structural wall surface. There are two leveling fixations on the same wall in the same plane, and the flat keel and the internal angle keel are vertically fixed on the leveling fixation. Before installing the waterproof wall panel, first fix the leveling fixation on the structural wall surface, and fix two on the same wall in the upper and lower parts. Adjust the leveling fixation to make the surface where the leveling fixation is fixed with the flat keel and the internal angle keel and the inner surface of the waterproof flange in the same plane. Then, during installation, just put the back of the flat keel and the internal angle keel with the leveling fixation to achieve the same plane for the entire wall.

[0011] Furthermore, when the gap between the back of the wall panel and the structural wall is filled with polyurethane foam, the plug of the flat keel and the internal corner clamp of the internal corner keel inserted in the keel slot of the wall panel, as well as the side of the wall panel inserted in the expansion groove, can prevent the expansion of polyurethane foam from causing the joints of two adjacent wall panels in different planes to separate from each other, prevent water leakage in the joints, and also prevent the joints of two adjacent wall panels in different planes from separating from each other due to vibrations in the daily life of residents, prevent water leakage in the joints.

[0012] Furthermore, when there are at least a plurality of leveling pads at the bottom of the chassis, and the tops of more than three leveling pads are in the same plane, the entire chassis can be supported. By using a spirit level, only a small number of leveling parts need to be leveled and checked, and there is no need to level the entire structural floor surface. The bottom of the chassis attached to the leveling pads and the bottom of the wall panel are parallel to the wall panel bottom fixer. When the tops of the leveling pads are in the same horizontal plane, the wall panel bottom fixer is in the same horizontal plane, and the wall panels overlapped above the wall panel bottom fixer will also be in the same horizontal plane. This structure can be realized The existing wall panels can be quickly leveled and installed quickly and accurately; when the gap between the bottom of the chassis and the structural floor is filled with ground polyurethane foam, after the chassis is fixed, the expansion of the polyurethane foam can realize the overall automatic leveling of the chassis and the bottom of the wall panel placed on the leveled leveling pad, which can achieve accurate and fast leveling, and the horizontal error can generally be controlled within ±1mm; the gap between the back of the wall panel and the structural wall is filled with wall polyurethane foam, and the expansion of the polyurethane foam can strongly adhere the back of the wall panel to the structural wall to prevent the wall from falling off.

[0013] Furthermore, there are no vertical holes on the water-facing surface of the chassis, and there is a floor drain groove on the water-facing surface of the chassis on the inner side of the wall panel; the floor drain groove is connected to the floor drain outlet, the floor drain groove is at the low part of the water-facing surface on the inner side of the waterproof flange, and the floor drain outlet is on the outer side of the waterproof flange, and the bottom of the inner wall of the floor drain outlet is not less than 5mm from the structural floor; thus, there are no vertical holes on the water-facing surface, which can eliminate the hidden dangers of chassis leakage. During installation, the bottom of the chassis can be directly attached to the leveled structural floor without overhead, which can reduce the hollow feeling of the chassis.
