Description

Technical Field

[0001] The utility model relates to an assembled wall panel connection structure, in particular to an assembled wall panel flat connection structure. Background Art

[0002] Traditional prefabricated wall panels are flat-jointed, difficult to adjust, have low precision, and the joints are prone to leaks. Summary of the Invention

[0003] The utility model aims to overcome the defects of the prior art and provide an assembled wall panel flat connection structure for connecting building wall panels, which enables flat connection of wall panels, is easy to adjust, and has joints that are not prone to water leakage.

[0004] The assembled wall panel flat connection structure described in the utility model includes a flat keel, a wall leveling device, and a flat wall panel. The characteristics are as follows: the flat keel includes an integrated structure of a backing surface, a water blocking strip, a joint strip, and a wall panel hook; the joint strip protrudes 6mm-15mm from the backing surface, the wall panel hook is at the front end of the joint strip, connected to the backing surface through the joint strip, and forms an "I" shape with the backing surface, and the length of the wall panel hook is shorter than the length of the backing surface; the length from the end of the wall panel hook to the center of the joint strip is between 2mm-8mm, and the length from the end of the backing surface to the center of the joint strip is between 10mm-20mm; the water blocking strip is on the backing surface, protruding 3mm-9mm from the backing surface, and the distance from the joint strip is not less than 5mm; the wall panel leveling device is fixed to the back of the backing surface and fixed to the structural wall panel by screws; there is a groove on the flat wall panel, and the groove is sleeved in the wall panel hook.

[0005] When used in construction, when there is no adjustment edge on the back of the butt-jointed keel, first use a spirit level to level the wall surface with the structural wall surface and fix it, then fix the butt-jointed keel to the adjustment edge, and then put the groove of the butt-jointed wall panel on the outside of the wall panel hook. Since the length of the wall panel hook is shorter than the length of the butt-jointed surface, and the length from the end of the wall panel hook to the center of the joint strip is between 2mm-8mm (generally about 4mm), the length from the end of the butt-jointed surface to the center of the joint strip is between 10mm-20mm (generally about 15mm), and the water-blocking strip is on the butt-jointed surface, protruding 3mm-9mm (generally about 5mm) from the butt-jointed surface, and the distance from the joint strip is not less than 5mm. Therefore, when the groove of the butt-jointed wall panel is put into the wall panel hook of the butt-jointed keel, the wall panel hook with a length of 2mm-8mm can prevent the hook from being too long, causing the side groove of the butt-jointed wall panel to be too deep, resulting in the side collapse of the butt-jointed wall panel, and at the same time can meet the requirements of the hook hanging the butt-jointed wall panel. The water blocking strip on the back surface is not less than 5mm away from the joint strip, and the protruding water blocking strip of 3mm-9mm on the back surface can prevent water from seeping through the adjacent flat wall panel joints. It is guided by the contact surface of the wall panel hook, flows out of the back of the flat wall panel, and flows out from the edge of the back surface, causing wall leakage. Even if water seepage occurs in the wall joints, the seepage water can only be guided to the bottom along the flow groove formed between the water blocking strip and the joint strip of the flat keel, and discharged from the nearest floor drain at the bottom. At the same time, when the flat When there is no adjustment edge on the back of the supporting surface of the connecting keel, the flow groove can become a hidden groove for concealing the leveling screw heads of the flat-jointed keel for fixing the wall, preventing the screw heads from making the flat-jointed wall panels difficult to install or damaging the flat-jointed wall panels; and the length of the supporting surface is greater than the length of the wall panel hook. Combined with the protruding water-blocking strip on the supporting surface, it can prevent water seepage from the wall and leak from the supporting surface, and can also serve as a guide for inserting the wall panel groove into the wall panel hook of the flat-jointed keel, making the installation and connection of the flat-jointed wall panels easier, simpler and more accurate; when there is an adjustment edge on the back of the end of the supporting surface that protrudes from the supporting surface by not less than 3mm, the wall leveling may include an L-shaped wall fixing surface and two adjustment strips, one end of which is fixed to the wall fixing surface at a single point and the other end is fixed to the adjustment edge at two points. This structure can adjust the distance between the wall and the flat-jointed keel through the movement of one adjustment strip, and then the other adjustment strip forms a triangular fixation with the fixed adjustment edge, thereby forming leveling stability for the flat-jointed keel and the wall panels connected to the flat-jointed keel.

[0006] In the assembled wall panel butt-joint connection structure of the utility model, the back side of the end of the butt-joint keel has an adjustment edge of no less than 3 mm.

[0007] The assembled wall panel flat connection structure described in the utility model comprises an L-shaped wall fixing surface and two adjustment strips with one end fixed to the wall fixing surface at a single point and the other end fixed to the adjustment edge at two points.

[0008] In the assembled wall panel flat connection structure of the utility model, a joint between the flat wall panels at the front end of the wall panel hook is filled with a caulking agent. BRIEF DESCRIPTION OF THE DRAWINGS
