Description

Technical Field

[0001] The invention relates to a keel, in particular to an assembled top plate keel system. Background Art

[0002] The bathroom and kitchen ceilings of traditional buildings are fixed to the roof of the building with expansion screws, and then the integrated top plate at the bottom is suspended with horizontal keels. As a result, the ceiling occupies a large space in the building height, and many holes for expansion screws need to be drilled in the roof of the building. Sometimes the holes will damage the waterproof layer on the upper floor, causing ground leakage. Therefore, the construction is complicated and is not suitable for buildings that require high space utilization in the building height (such as LOFT apartment buildings and other buildings). Summary of the invention

[0003] The present invention aims to overcome the defects of the prior art and provide a kind of assembled top plate keel system for use in buildings, which can improve the utilization rate of building height space, eliminate the need for numerous expansion screws on the roof for ceiling (except for fixing anchor bolts for large lamps and bathroom heaters or long distances of top plates), and can realize rapid installation of top plates and wall panels, thereby improving installation efficiency.

[0004] The assembled roof keel system of the present invention comprises a roof keel, a roof panel, a wall panel, a corner fixing piece, a fixing screw and a fixing glue; the characteristics are as follows: the roof keel comprises a wall panel sleeve groove, a wall panel limiting strip, a roof panel placement strip and a fixing area which are integrated into a structure; the wall panel sleeve groove is U-shaped, with an opening downward, and is sleeved on the top of the wall panel. In this structure, the U-shaped wall panel sleeve groove can be sleeved on the outer wall of the wall panel, and the U-shaped groove can conceal the unevenness of the top of the wall panel, and two adjacent wall panel limiting strips can be adjusted up and down, so that the joints of the two intersecting roof panel placement strips are 90 degrees; the wall panel limiting strip is above the top of the wall panel, The top of the wall panel limit strip is a fixing area, and the length of the fixing area is more than 3mm and less than 70mm. Therefore, the wall panel limit strip can limit the top of the wall panel, so that the top of the wall panel will not reach the fixing area above the wall panel limit strip, preventing the fixing screws from fixing the top panel keel from the corner fixing piece, damaging the top of the wall panel or failing to fix the top panel keel; the top panel placement strip protrudes horizontally from the outer wall of the inner side of the wall panel sleeve groove by 5mm-50mm, thereby forming a fault-tolerant structure that allows wall panel installation errors. When the tops of the two opposite wall panels are installed slightly larger or smaller, the top panel placement strip can conceal the defects of the outer periphery of the top panel placed on the top panel placement strip. This structure can reduce the difficulty of construction and facilitate the rapid installation of the top panel; the top panel is placed on the top panel placement strip, and at least one top panel connecting the two opposite top panel placement strips is an integral panel without a break in the middle. The fixing glue fixes the joint between the top panel placement strip and the top panel. Therefore, after the top panel keel fixes the top of the wall panel, the top panel is placed on the top panel placement strip, and the fixed The glue fixes the joint between the top plate and the top plate placement strip, and the whole plate without any breaks in the middle makes the top plate, top plate placement strip and wall plate form a structure that is fixed, pulled and resisted from each other. This can prevent the top plate from collapsing or cracking when there are heavy objects on the top plate (such as bathroom heaters, lamps and the weight of the top plate itself). Therefore, the installation of the top plate does not require the use of screws and expansion screws to fix the structural roof and the top plate (of course, it does not rule out the use of screws to fix the bathroom heater connection frame and the roof when installing the bathroom heater). At the same time, the structure can also enhance the anti-impact and anti-lodging performance of the wallboard. This structure can simplify the installation process, improve work efficiency, and increase the building height and space utilization. The seam of the overlapping surface of the top plate and the top plate placement strip is fixed by fixing the top plate with glue. The fixed contact surface is large, which can increase the tensile and compressive strength of the overall wall and top plate, and can also play a role in beauty and easy construction. The end of each top plate keel is 45 degrees or close to 45 degrees laterally inside; the corner fixing piece is a U-shaped right angle or close to right angle downward sleeve groove;The corner fixing piece is sleeved on the outside of the wall panel sleeve groove of the ends of the two intersecting top panel keels above the top panel placement strip. As a result, the U-shaped right-angled or nearly right-angled downward sleeve groove of the corner fixing piece can become a guide groove for installing two adjacent top panel keels. As long as the ends of the two top panel keels at 45 degrees or nearly 45 degrees are inserted into the U-shaped right-angled or nearly right-angled downward sleeve groove, and the top panel keel is pressed tightly, the edge of the U-shaped right-angled or nearly right-angled corner fixing piece will automatically and accurately correct the 45-degree joint of the end of the top panel keel, so that the ends of the two top panel keels are spliced ​​at 90 degrees. When the top panel keels at the top of multiple wall panels are adapted to the width of the wall panels, as long as the 45-degree inclined surface of the end of the top panel keel on the top of the wall panel is inserted into the corner fixing piece, and after tightening, it is fixed by the fixing screws. By fixing the top plate keel, it is possible to quickly correct and install multiple wall panels, prevent the joint gaps of the intersecting wall panels from being unclosed and uneven, and improve the installation accuracy and speed of the wall panels and top plates; the fixing screws are used to laterally fix the corner fixings and the fixing area above the wall plate limit strip of the top plate keel on the inner side of the corner fixings. Since the corner fixings are above the top plate placement strip, there is a 3mm-70mm fixing area above the wall plate limit strip. Therefore, the fixing screws can laterally fix the corner fixings and the top plate keel on the inner side of the corner fixings. The inner side of the corner fixings and the overlapping area of ​​the top plate are generally the activity space of the room, so there is ample installation space, and there is no need to use the space on the top of the top plate keel to install the top plate keel, thereby improving the utilization rate of the building height space. ;

[0005] Furthermore, the depth of the wall panel groove is between 40mm-20mm, so the adjustment space of the wall panel groove for the wall panel can be between 40mm-20mm; the height of the fixed area is between 5mm-20mm, and this space provides a fixing space for the fixing screws; the length of the top plate placement strip is between 5mm-35mm, so the adjustment space of the top plate can be controlled between 3mm-30mm, reducing the accuracy requirements on the top plate edge size and improving the installation speed.
