DETAILED DESCRIPTION

[0030] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] For example, see Figures 1 to 6 The present invention provides a technical solution: an assembled ceiling, comprising: a plurality of long beams 1 and gypsum boards 10, support plates 8 are fixedly installed on both ends of the long beams 1, the lower end of the support plate 8 is flush with the lower end of the long beam 1, the support plate 8 and the long beam 1 are integrally formed, and a plurality of concave holes 9 are evenly opened on the side wall of the support plate 8. When a putty layer 25 is applied by brushing, the concave holes 9 increase the friction between the putty layer 25 and the putty layer 25, so that the putty layer 25 is not easy to fall off.

[0032] A limiting slide groove 17 is provided at the upper end of the long beam 1, and a limiting slide groove 2 19 is provided at the lower end of the long beam 1. The limiting slide groove 17 and the limiting slide groove 2 19 are both convex, and a plurality of limiting sleeves 2 are evenly slidably connected in the limiting slide groove 7. One end of the limiting sleeve 2 is threadedly connected with a lifting screw 5. The limiting sleeve 2 is truncated cone-shaped, and a threaded hole 20 is provided at one end of the limiting sleeve 2. The outer wall of the other end of the limiting sleeve 2 is slidably connected to the inner wall of the limiting slide groove 17, so that the limiting sleeve 2 can slide arbitrarily in the limiting slide groove 17, thereby changing the position of the lifting screw 5. The outer wall of one end of the lifting screw 5 is threadedly connected to the inner wall of the threaded hole 20, and the lifting screw 5 is fixed to the lower end of the limiting sleeve 2.

[0033] The end of the lifting screw rod 5 away from the limiting sliding sleeve 2 is connected with an expansion bolt 6, and the lifting screw rod 5 is fixedly installed on the roof by the expansion bolt 6. The outer end of the lifting screw rod 5 is threadedly connected with a threaded sleeve 3, and the threaded sleeve 3 is in contact with the outer wall of the long beam 1. A threaded hole 4 is opened at the center of one end of the threaded sleeve 3. One end of the lifting screw rod 5 passes through the threaded sleeve 3, and the outer wall of the lifting screw rod 5 is threadedly connected with the inner wall of the threaded hole 4. The threaded sleeve 3 is rotated to make the lower end outer wall of the threaded sleeve 3 contact the upper end outer wall of the long beam 1, so as to fix the lifting screw rod 5 and the long beam 1 together.

[0034] A plurality of short beams 11 are arranged between two adjacent long beams 1, and a pressure plate 12 is fixedly installed on the upper end of each short beam 11. The pressure plate 12 and the short beam 11 form a convex shape. The pressure plate 12 is connected to the long beam 1 and the gypsum board 10 through a connecting component. The connecting component includes a fixing ear 13 fixedly installed on both the front and rear sides of the upper end of the pressure plate 12. The side wall of the fixing ear 13 is provided with a screw hole. The fixing ear 13 is attached to the side end of the long beam 1. The screw 23 passes through the screw hole and is screwed into the long beam 1 to fix the left and right ends of the short beam 11 on the side walls of the two long beams 1 to form a lifting frame.

[0035] The left and right ends of the gypsum board 10 are overlapped on the support plate 8 at one end of the two adjacent long beams 1, and the left and right ends of the gypsum board 10 are provided with overlap grooves 24. The overlap grooves 24 at the left and right ends of the gypsum board 10 are overlapped on the upper ends of the two adjacent support plates 8, and the left and right ends of the gypsum board 10 are respectively in contact with the side walls of the two adjacent long beams 1, and the lower end of the gypsum board 10 is flush with the lower end of the support plate 8. The front and rear ends of the two adjacent gypsum boards 10 are connected with short beams 11, and the front and rear sides of the short beam 11 are respectively in contact with the front or rear ends of the two adjacent gypsum boards 10 in the front and rear directions. The lower end of the pressing plate 12 is in contact with the upper ends of the two adjacent gypsum boards 10. The ends of the short beam 11 are in contact with each other, and the left and right ends of the short beam 11 are fixed to the outer walls of the two adjacent long beams 1 by fixing ears 13 and screws 23 to fix the gypsum board 10. For each gypsum board 10 installed, a short beam 11 is installed, and the short beam 11 is used to separate the multiple gypsum boards 10. At the same time, the pressing plate 12 is pressed to the two sides of the gypsum board 10, and cooperates with the lower supporting support of the support plate 8 to form a limiting fixing effect on the upper and lower surfaces, thereby ensuring the fixing strength of the gypsum board 10. Moreover, compared with the existing screw fixing method, the one-support-one-press support method has higher fixing stability. The lower surface of the gypsum board 10 and the support plate 8 are coated with a putty layer 25.

[0036] A plurality of limit sliders 14 are slidably connected in the limit slide groove 19. The limit slider 14 is convex, and the lower end of the limit slider 14 is located in the limit slide groove 19. A notch 17 is provided at the upper end of the limit slider 14, and a rubber pad 15 is inserted into the notch 17. A threaded hole 3 21 is provided on the side wall of the rubber pad 15, and a threaded hole 4 22 is provided on the side wall of the limit slider 14. When the rubber pad 15 is inserted into the notch 17, the threaded hole 4 22 is connected to the threaded hole 3 21, and the threaded hole 4 22 at the lower end of the limit slider 14 is inserted into the hole Plug 18, the hole plug 18 is located in the limiting slide groove 2 19. When installing hoisting equipment such as some decorations, you can first remove the hole plug 18 and use bolts or screws to install it at the position of the threaded hole 4 22. In this way, there is no need to temporarily open a hole on the gypsum board 10 or the long beam 1, and the limiting slider 14 slides in the limiting slide groove 2 19 to adjust the fixed position for easy fixation. When brushing putty, directly cover the limiting slide groove 2 19 and the unused limiting slider 14 and the hole plug 18, which will not affect the beauty of the ceiling.

[0037] Before installation, first drill a hole on the top of the floor slab, then install the lifting screw rod 5 through the expansion bolt 6 to maintain the lifting height, then screw on the threaded sleeve 3 and the limiting sleeve 2 respectively, and then lift and fix the long beam 1 through the limiting sleeve 2 through the limiting sliding relationship between the limiting sleeve 2 and the limiting slide groove 7, and level it to maintain the lifting height, then tighten the threaded sleeve 3 so that it cooperates with the limiting sleeve 2 to tightly press against the long beam 1 to form a fixation, cut the side of the gypsum board 10 according to the support plate 8 to form a lap groove 24, and at the same time apply glue to the lap groove 24 and the top surface of the support plate 8, and then place the gypsum board 10, relying on the support of the support plate 8 and the glue to fix it, and after the lifting is completed, apply the putty layer 25 on the surface, and the concave hole 9 on the bottom surface of the support plate 8 increases the contact surface with the putty layer 25 to ensure the adhesion strength of the putty layer 25;

[0038] Moreover, at present, the method of drilling expansion bolt holes is simpler, that is, marking lines on the roof slab, and manually drilling holes on the lines at visual spacing. Some advanced methods use laser levels, and holes are also drilled at visual spacing according to the instructions of the laser lines. The holes drilled have lines as indicators and basically do not go beyond the lines, but the spacing cannot be guaranteed. The limiting sliding sleeve 2 slides and supports in the limiting sliding groove 7 of the long beam 1, which can compensate for the error influence of unequal spacing, and can ensure that the lifting screw 5 lifts the long beam 1 vertically, thereby ensuring the level of the entire ceiling.

[0039] For example 2, please refer to Figure 7 On the basis of the first embodiment, the present embodiment includes a connecting component, which includes an elastic metal plate 27 fixedly installed on the front and rear sides of the upper end of the pressing plate 12 and a connecting groove 26 opened on the side wall of the long beam 1. The left and right sides of the lower end of the pressing plate 12 are fixedly installed with a plug-in strip 31, and the lower end of the plug-in strip 31 is inserted into the gypsum board 10. The outer end of the elastic metal plate 27 is fixedly installed with a connecting block 28 and a threaded adjusting bolt 29. The elastic metal plate 27 inserts the connecting block 28 into the connecting groove 26 by deformation, so that the pressure strip 12 can be moved and limited.

[0040] The outer end of the connecting block 28 is slidably inserted into the connecting groove 26, and a plug-in groove 30 is opened in the upper groove at one end where the gypsum board 10 and the pressure strip 12 are connected. The pressure strip 12 is pressed against the upper ends of the two gypsum boards 10, and the plug-in strip 31 is inserted into the plug-in groove 30, and then the adjusting bolt 29 is tightened so that its inner end is in close contact with the side wall of the long beam 1, thereby fixing the pressure strip 12.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
