Description

Technical Field

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

[0002] In traditional prefabricated wall panels, flat joints are difficult to adjust, have low precision, and the joints are prone to leakage. Summary of the Invention

[0003] The utility model aims to overcome the defects of the prior art and provides a wall panel flat joint keel for connecting building wall panels, which enables flat joint connection of wall panels, is easy to adjust, and has no tendency to cause water leakage at the joints.

[0004] The wall panel flat-jointed keel described in the utility model includes a leaning surface, a water-blocking strip, a joint strip, and a wall panel hook in an integrated structure; the joint strip protrudes 6mm-15mm from the leaning surface, the wall panel hook is at the front end of the joint strip, connected to the leaning surface via the joint strip, and forms an "I" shape with the leaning surface, and the length of the wall panel hook is shorter than the length of the leaning 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 leaning surface to the center of the joint strip is between 10mm-20mm; the water-blocking strip is on the leaning surface, protruding 3mm-9mm from the leaning surface, and is not less than 5mm away from the joint strip.

[0005] When used in construction, when there is no adjustment edge on the back of the butt joint keel, first use a spirit level to level the wall surface with the structural wall surface and fix it, then fix the butt joint keel to the adjustment edge, and then put the groove of the butt joint 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 joint, 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 joint to the center of the joint strip is between 10mm-20mm (generally about 15mm), and the water barrier strip is on the butt joint, protruding 3mm-9mm (generally about 5mm) from the butt joint, and the distance from the joint strip is not less than 5mm. Therefore, when the groove of the butt joint wall panel is put into the wall panel hook, 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 joint wall panel to be too deep, resulting in the side collapse of the butt joint wall panel, and at the same time can meet the requirements of the hook hanging on the slot of the butt joint wall panel. The water-blocking strip on the back surface, which is not less than 5mm away from the joint strip and protrudes 3mm-9mm from the back surface, can prevent water from seeping through the wall through the adjacent flat wall panel joints. It is guided by the contact surface of the wall panel hooks, 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 can only be guided to the bottom along the flow channel 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 keel When there is no adjustment edge on the back of the back surface of the keel, the flow groove can become a hidden groove for concealing the leveling screw heads of the flush keel to fix the wall, preventing the screw heads from making the flush wall panels difficult to install or damaging the flush wall panels; and the length of the back surface is greater than the length of the wall panel hook. Combined with the protruding water-blocking strip on the back surface, it can prevent water from seeping out of the wall and leaking out of the back surface, and can also guide the wall panel groove to insert into the wall panel hook of the flush keel, making the installation and connection of the flush wall panel easier, simpler and more accurate; when there is an adjustment edge on the back of the end of the back surface that protrudes from the back 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 flush keel through the movement of one adjustment strip, and then the other adjustment strip forms a triangular fixation with the fixation of the adjustment edge, thereby forming leveling stability for the flush keel and the wall panels connected to the flush keel.

[0006] The wall panel butt-joined keel of the utility model has an adjustment edge of no less than 3mm on the back side of the end portion thereof facing the surface.

[0007] The wall panel flat-joined keel of the utility model has a wall leveling device fixed on the back of the leaning surface; the wall leveling device includes 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.
