Description

Technical Field

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

[0002] The internal corner connections of traditional prefabricated wall panels are difficult and of low precision, and the joints are prone to water leakage. Summary of the Invention

[0003] The utility model aims to overcome the defects of the prior art and provides an assembled wall panel internal angle connection structure for connecting building wall panels, which makes it easy to connect internal angle wall panels and makes it difficult for the joints to leak.

[0004] The assembled wall panel internal angle connection structure described in the present invention includes an internal angle keel, a telescopic wall panel, and a buckled wall panel. It is characterized in that the two supporting surfaces of the internal angle keel are L-shaped and generally have an angle of about 90 degrees. The inner side surfaces of the two supporting surfaces have a wall panel backrest that protrudes 3mm-15mm from the inner side surface. When water flows into the internal angle keel at the joint between the telescopic wall panel and the buckled wall panel, the wall backrest can prevent the water from leaking out quickly from the end of the internal angle keel, so that the water leakage in the joint will be blocked by the wall backrest protruding from the internal angle keel, and flow along the internal angle keel on the back of the wall panel to the floor drain at the bottom of the internal angle keel for discharge. Each supporting surface generally has 2 or more wall panels on the inner side surface. The board backrest can prevent water leakage from the joints in multiple ways and can also play a role in correcting the wallboard. At the same time, it can also be used as a fixing point for the internal angle keel and the adjustment piece. The thickness is 3mm-15mm. When using screws to fix the adjustment piece, it can prevent the screw head from being exposed and affecting the connection of the wallboard (telescopic wallboard, buckle wallboard); the inner side of one of the leaning surfaces has a wallboard hook that is 2mm-8mm longer than the wallboard backrest. Therefore, the slot of the buckle wallboard is inserted into the outside of the plug of the wallboard hook, ensuring that the hanging edge thickness of 2mm-8mm ensures that the wallboard hook can The wall panels are stably fixed to prevent the groove edges of the wall panels from cracking; the wall panel hooks are L-shaped and on the inner side of the same side, with a horizontal distance of not less than 3mm from the side of the same side, thereby forming a drainage groove of not less than 3mm, which can slow down the leakage of the joints in the space and drain to the bottom of the internal angle keel, preventing the drainage groove from being too short, causing the leakage to cross the side and cause wall leakage; the distance between the back of the wall panel hook and the back of the other wall panel is not less than 5mm, thereby forming the wall panel expansion and contraction formed by the distance between the back of the wall panel hook and the back of the other wall panel After the compensation groove is inserted into the wall panel with a thickness of more than 5mm, even if the wall surface is not very flat, the compensation groove can conceal the defects of the wall panel joints, so as to play the role of fast and accurate installation of the wall panel; the side of the snap-on wall panel has a groove, and the plug of the wall panel hook is inserted into the groove; the telescopic wall panel is inserted into the space between the back of the wall panel hook and the back of the other wall panel, and the side of the telescopic wall panel does not expose the inner surface of the snap-on wall panel. This structure forms the side of the snap-on wall panel to press the inner surface of the telescopic wall panel, preventing the snap-on wall panel and the telescopic wall panel from detaching, making the joint beautiful and leak-proof.

[0005] Furthermore, one leaning surface of the internal angle keel is fixed to the adjusting member, and the adjusting member is fixed to the structural wall. The adjusting member fixes one surface of the internal angle keel and can also fix two surfaces of the internal angle keel.

[0006] Furthermore, the end of the internal angle keel with the wall panel hook has an adjustment edge protruding from the back surface by not less than 3 mm. The adjustment edge is at the end of the back surface with the wall panel hook. After the internal angle keel expansion groove formed in the space between the back side of the wall panel hook and the back of the other wall panel is inserted into the telescopic wall panel, there is space to fix the adjustment edge of the end of the back surface with the wall panel hook on the internal angle keel at the corner with the wall panel hook to the adjustment part, and it is leveled and fixed to the structural wall through the adjustment part. However, if the adjustment edge is at the end of the other back surface, there is no space to fix the telescopic wall panel after it is inserted.

[0007] Furthermore, the adjustment member 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. This structure can adjust the distance between the wall and the internal angle keel through the movement of one adjustment strip, and then the other adjustment strip is fixed to the adjustment edge to form a triangular fixation, thereby achieving leveling stability of the internal angle keel and the wall panel connected to the internal angle keel.

[0008] In the assembled wall panel internal angle connection structure described in the utility model, one leaning surface of the internal angle keel is fixed to the adjusting member, and the adjusting member is fixed to the structural wall surface.

[0009] In the assembled wall panel internal angle connection structure of the utility model, the end of the internal angle keel with the wall panel hook on the supporting surface has an adjustment edge protruding from the supporting surface by no less than 3 mm.

[0010] The assembled wall panel internal angle connection structure described in the utility model comprises an L-shaped wall fixing surface and two adjusting strips with one end fixed to the wall fixing surface at a single point and the other end fixed to the adjusting edge at two points.
