Abstract
Description
Technical Field
[0001] The invention relates to a keel, in particular to a internal angle keel. Background Art
[0002] The traditional assembled internal corners and wall panels are difficult to connect, the precision is not high, and the joints are prone to leakage. Summary of the invention
[0003] The present invention aims to overcome the defects of the prior art and provide a kind of internal angle keel used in the connection of building wall panels, which makes it easy to connect the internal angle wall panels and prevents water leakage from occurring at the joints.
[0004] The internal angle keel described in the present invention includes two supporting surfaces with an L-shaped angle, the angle is generally about 90 degrees, and the inner side surfaces of the two supporting surfaces are provided with a wall panel backrest protruding from the inner side surface by 3mm-15mm. 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 supporting surface generally has 2 or more wall panel backrests, thereby, multiple barriers can be used to block water leakage in the joint, and can also It plays the role of 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 plug-in of the wallboard. The inner side of one of the backing surfaces has a wallboard hook that is 2mm-8mm longer than the back of the wallboard. Therefore, a side slot of a wallboard is inserted outside the plug of the wallboard hook, ensuring a hanging edge thickness of 2mm-8mm, ensuring that the wallboard hook can stably fix the buckled wallboard and prevent the groove edge of the buckled wallboard from cracking. The wallboard hook is L-shaped, and on the inner side of the same side of the backing surface, the horizontal spacing with the same side of the backing 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, so as to play the role of fast and accurate installation of the wall panel; the end of the back surface with the wall panel hook has an adjustment edge protruding from the back surface by not less than 3mm, and the adjustment edge is at the wall panel hook After the expansion groove of the internal angle keel formed by the space between the back side of the wall panel hook and the back of the other wall panel is inserted into the wall panel, there is space to fix it with the adjusting part on the adjusting edge of the end of the wall panel hook at the corner, and the adjusting part is leveled and fixed to the structural wall surface. At the same time, the spacing space between the back side of the wall panel hook and the back of the other wall panel can become a compensating expansion joint for adjusting the insertion depth of the wall panel. If the adjusting edge is at the end of the other side of the wall panel, there is no space to fix the adjusting part after the telescopic wall panel is inserted, and the spacing space between the back side of the wall panel hook and the back of the other wall panel cannot become a compensating expansion joint for adjusting the insertion depth of the wall panel.
[0005] Furthermore, one of the leaning surfaces of the internal angle keel is fixed to an adjusting member, and the adjusting member is fixed to the structural wall. The adjusting member 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 triangle, 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 present invention 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 present invention has an adjusting piece comprising 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.
