Description

Technical Field

[0001] The utility model relates to a keel, in particular to a female angle keel. Background Art

[0002] The connection between traditional prefabricated internal corners and wall panels is difficult, the precision is not high, 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 kind of internal angle keel used 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 internal angle keel described in the present invention includes two leaning surfaces with an L-shaped included angle, which is generally about 90 degrees. The inner side surfaces of the two leaning surfaces are all provided with a wall panel backrest that protrudes 3mm-15mm from the inner side surface. Therefore, when the internal angle keel is inserted into the wall panel, when water flows into the internal angle keel at the joint of the two wall panels, the wall backrest can prevent water leakage from the end of the internal angle keel quickly, 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 near the bottom of the internal angle keel for discharge. Each inner side surface of the leaning surface generally has two or more wall panel backrests. Therefore, water leakage in the joint can be blocked in multiple ways, and It can correct the wall panels and serve 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, which will affect the connection of the wall panels. The inner side of one of the supporting surfaces has a wall panel hook that is 2mm-8mm longer than the back of the wall panel. Therefore, the side slot of a wall panel is inserted into the plug of the wall panel hook, ensuring a hanging edge thickness of 2mm-8mm to ensure that the wall panel hook can stably fix the buckled wall panel and prevent the groove edge of the buckled wall panel from cracking. The wall panel hook is L-shaped, and on the inner side of the same side of the supporting surface, the horizontal distance from the same side of the supporting surface is not less than 3mm. , thus, a drainage groove of not less than 3mm is formed, which can slow down the leakage of the joint in the space and drain it to the bottom of the internal angle keel, preventing the drainage groove from being too short, causing the leakage to cross the back surface 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. Thus, the wall panel expansion compensation groove formed by the distance between the back of the wall panel hook and the back of the other wall panel can conceal the defects of the wall panel joint after inserting the wall panel with a thickness of more than 5mm, even if the wall surface is not very flat, and play the role of fast and accurate installation of wall panels; the end of the back surface with wall panel hook has an adjustment edge protruding from the back surface by not less than 3mm, and the adjustment edge is at the back surface with wall panel hook The end of the leaning surface, and the internal angle keel expansion groove formed by the space between the back of the wall panel hook and the back of the other wall panel, are inserted into the wall panel, so there is space to fix it with the adjusting part on the adjusting edge of the end of the leaning surface with the wall panel hook at the corner, and the adjusting part is leveled and fixed to the structural wall. At the same time, the spacing space between the back of the wall panel hook and the back of the other wall panel can become a compensating expansion joint for adjusting the depth of wall panel insertion. If the adjusting edge is at the end of the leaning surface on the other side, there is no space to fix the adjusting part after the telescopic wall panel is inserted, and the spacing space between the back of the wall panel hook and the back of the other wall panel cannot become a compensating expansion joint for adjusting the depth of wall panel insertion.

[0005] Furthermore, one of the leaning surfaces of the internal angle keel is fixed to the adjusting part, and the adjusting part is fixed to the structural wall. The adjusting part can be a leveling horizontal keel or a leveling point, which plays the role of leveling and fixing the internal angle keel. It can fix one surface of the internal angle keel or both surfaces of the internal angle keel.

[0006] 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.

[0007] The internal angle keel of the utility model has a leaning surface fixed to the adjusting member, and the adjusting member is fixed to the structural wall surface.

[0008] The internal angle keel of the utility model comprises an L-shaped wall fixing surface and two adjusting strips, one end of which is fixed to the wall fixing surface at a single point and the other end is fixed to the adjusting edge at two points. BRIEF DESCRIPTION OF THE DRAWINGS
