Description

Technical Field

[0001] The utility model relates to the field of decoration, and more specifically, to a quick clamping device for an integrated ceiling plate. Background Art

[0002] Integrated ceilings are generally used in kitchens and bathrooms. Integrated ceilings are composed of many modules, each of which can be installed separately in the ceiling. Ordinary ceilings require main materials and many spare parts, which are more troublesome to install. Secondly, the integrated ceiling has a beautiful and uniform appearance. When installing the integrated ceiling panel, you need to use a thinner keel. When the indoor area is too large, the bearing capacity of a large number of panels will be weakened. After a long time, the keel will bend and the panel will fall off easily. If a thicker rigid keel is used, the installation efficiency of the panel will decrease, and it is not easy to ensure the sealing between the panel and the keel.

[0003] After the integrated ceiling panels are assembled, due to the gaps reserved between the panels, water leaking from the pipes above the ceiling is easy to drip down through the gaps in the panels. After installing a ventilation module with a motor, the motor will cause the panels to vibrate slightly when it is running. The panels of the module with the motor will collide with the surrounding panels and make noise. Bolts are required when assembling the existing ceiling keels and anchor rods, which takes a long time to install and reduces the overall efficiency of the ceiling installation. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an integrated ceiling panel quick-clamping device to solve the problem that the panel surface of the module with a motor may collide with the surrounding panel surfaces and generate noise.

[0005] The utility model provides an integrated ceiling panel quick clamping device, which is achieved by the following specific technical means: comprising an anchoring part for hoisting a panel surface part, a keel part with a long strip shape, which is used to be fixed on the edge of the wall supporting the panel surface part, a quick hoisting structure is arranged between the keel part and the anchoring part, the keel part comprises a wall keel a, a middle keel and a wall keel b which are fitted with the wall surface, the wall keel a and the wall keel b have the same structure, and are respectively installed at the left and right ends of the panel surface part, the bottom of the middle keel is an inverted T-shaped structure, and through holes are horizontally penetrated at the top vertical surfaces of the wall keel a, the middle keel and the wall keel b. Used for fixing screws to the wall, having a flat-plate-shaped plate portion, located at the interval of the keel portion, a plate clamping structure for quickly clamping the plate portion and the keel portion, a leak-proof sealing structure for sealing the joint edge of the plate portion, used to prevent water leakage above the suspended ceiling, the anchoring part includes a square tube, a plate seat is provided on the top of the square tube, through holes for installing expansion screws are vertically penetrated at the corners of the plate seat, a circular through hole is horizontally penetrated at the bottom of the square tube, an insertion rod is inserted inside the square tube, and a fixed-distance hole is horizontally penetrated by the insertion rod, and the fixed-distance hole is used to insert a fixed-distance bolt with the circular through hole horizontally penetrated at the bottom of the square tube, so as to determine the extension length of the insertion rod.

[0008] According to this plan, after the anchoring part is fixed to the roof, the keel is lifted upward, and the sleeve is inserted upward along the intersection of the arc surface and the bottom of the hook. After the sleeve moves to the top of the wedge hook, the keel is moved horizontally to the right and then pulled downward, so that the sleeve can be inserted downward into the wedge hook, and supported by the rebound of the roll sheet. After the wedge hook bends and resets, it can limit the top of the sleeve, prevent the sleeve from moving up, down, left and right, and quickly lift the keel.

[0016] According to the scheme, after the front and back of the spliced ​​panels are spliced ​​together, the toothed hot-melt adhesive strips at the front and rear ends of the panel are interlaced. After the spliced ​​panels are clamped on the side of the keel through the panel surface clamping structure, the long strips of soft adhesive in the groove will fit tightly with the bottom surface of the keel.
