Description

Technical Field

[0001] The invention 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 leaks. Summary of the invention

[0003] The present invention aims to overcome the defects of the prior art and provide a wall panel flat joint keel used in the connection of building wall panels, which enables the wall panels to be flatly connected, is easy to adjust, and the joints are not prone to water leakage.

[0004] The wall panel flat-jointed keel described in the present invention comprises a leaning surface, a water blocking strip, a joint strip, and a wall panel hook in an integrated structure; the joint strip protrudes from the leaning surface by 6mm-15mm, the wall panel hook is at the front end of the joint strip, connected to the leaning surface via the joint strip, and is in 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, protrudes from the leaning surface by 3mm-9mm, and is not less than 5mm away from the joint strip.

[0005] Applied in construction, when there is no adjustment edge on the back of the flat-jointed keel, first use a spirit level to level the wall surface with the structural wall surface, then fix the flat-jointed keel to the adjustment edge, and then put the groove of the flat-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 back 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 back surface to the center of the joint strip is between 10mm-20mm (generally about 15mm), and the water-blocking strip is on the back surface, protruding 3mm-9mm (generally about 5mm) from the back surface, and the distance from the joint strip is not less than 5mm, therefore, when the groove of the flat-jointed 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 flat-jointed wall panel to be too deep, resulting in the side collapse of the flat-jointed wall panel, and at the same time can satisfy the hook to hang the slot of the flat-jointed wall panel. The water-blocking strip on the back surface and the protruding 3mm-9mm from the back surface with a distance of not less than 5mm from the joint strip can prevent water from seeping through the wall through the adjacent flat wall panel joints, and being guided by the contact surface of the wall panel hooks, flowing out of the back of the flat wall panel, and flowing 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 When there is no adjustment edge on the back of the keel's back surface, the flow groove can become a hidden groove for concealing the flat keel to fix the wall leveling screw head, preventing the screw head from making the flat wall panel difficult to install, or the screw head from damaging the flat wall panel; 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 play a role in guiding the wall panel groove to insert into the wall panel hook of the flat keel, making the installation and connection of the flat wall panel easier, simpler and more accurate; when there is an adjustment edge protruding from the back surface by not less than 3mm on the end of the back surface, the wall leveling can include 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. This structure can adjust the distance between the wall and the flat keel through the activity of one adjustment strip, and then the other adjustment strip and the fixing of the adjustment edge form a triangular fixation, forming the leveling stability of the flat keel and the wall panel connected to the flat keel.

[0006] The wall panel butt-jointed keel of the present invention has an adjustment edge of not less than 3 mm on the back side of the end of the butt-jointed keel.

[0007] The wall panel flat keel of the present invention has a wall leveler fixed on the back of the leaning surface; the wall leveler includes 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.
