Detailed implementation manners

[0026] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] Please refer to Figures 1 to 7, an anti-seismic keel structure for an anti-seismic ceiling is provided in an embodiment of the present application, which includes a mounting base 1, a column 2, a horizontal keel 3, and a right-angle connector 4. The lower end of the column 2 is connected to the horizontal keel 3. Mounting bases 1 are installed at the upper end of the column 2 and at one end of the horizontal keel 3 that is not connected to the column 2. The mounting base 1 at the upper end of the column 2 is connected to the roof, and the mounting base 1 connected to the horizontal keel 3 is connected to the wall. The horizontal keels 3 are distributed in a straight shape, an L shape, a T shape, or a cross shape on a reference plane perpendicular to the column 2. The column 2 and the horizontal keel 3, as well as between two adjacent horizontal keels 3 with an included angle of 90 degrees, are all connected by the right-angle connector 4. In the anti-seismic keel structure in the non-edge area of the anti-seismic ceiling, the horizontal keels 3 are distributed in a cross shape, while in the edge area, they can be distributed in a straight shape, an L shape, or a T shape. Mounting bases 1 are installed at one end of the horizontal keels 3 in the edge area facing the edge. Among them, the column 2 is used to bear the vertical load of the ceiling, and the horizontal keel 3 is used to cope with the horizontal force and bear the anti-seismic function of the ceiling. The anti-seismic function is realized by closely connecting the horizontal keel 3 with the building structure. The column 2 and the horizontal keel 3 can be stably connected through the right-angle connector 4, improving the overall strength of the anti-seismic keel.

[0028] Among them, the mounting base 1 includes a fixing plate 11 and a U-shaped steel 12 fixedly connected to the fixing plate 11. Both the column 2 and the horizontal keel 3 are square steel pipes adapted to the U-shaped steel 12. A number of equally spaced round holes 5 are opened on four side surfaces of the square steel pipe, and the round holes 5 on adjacent side surfaces are staggered. One end of the square steel pipe is located inside the U-shaped steel 12 and is connected to the U-shaped steel 12.

[0029] The round holes 5 on adjacent side surfaces of the square steel pipe are staggered, which can ensure the overall strength of the square steel pipe. If the round holes 5 are too concentrated in a cross-sectional area of the square steel pipe, it will cause the strength of the square steel pipe at the concentrated area of the round holes 5 to be small and easy to break.

[0030] Two first kidney-shaped holes 121 are opened on three side surfaces of the U-shaped steel 12. The U-shaped steel 12 and the square steel pipe are connected by a first bolt assembly 6 passing through the first kidney-shaped holes 121 and the round holes 5. The first bolt assembly 6 is set to two or four. When the first bolt assembly 6 is set to two, the two first bolt assemblies 6 pass through the two first kidney-shaped holes 121 on one side surface in the middle of the U-shaped steel 12 and then pass through the round holes 5 to be connected to the square steel pipe. When the first bolt assembly 6 is set to four, on this basis, the other two first bolt assemblies 6 pass through the two first kidney-shaped holes 121 on the two side surfaces at the edge of the U-shaped steel 12 and the round holes 5, so as to be connected to the square steel pipe in a tension way. By setting the first kidney-shaped holes 121, it is convenient for the three side surfaces of the U-shaped steel 12 and the staggered round holes 5 on the adjacent side surfaces of the square steel pipe to have a coincidence area at the same time, which is convenient for fitting and connecting.

[0031] The right-angle connector 4 includes a connecting end face 41 and an arc-shaped side face 42. There are two connecting end faces 41 which are perpendicularly arranged. The arc-shaped side face 42 is located on both sides of the connecting end face 41. Two groups of mounting holes 411 are provided on the connecting end face 41. The two groups of mounting holes 411 are arranged in a straight line. Each group of mounting holes 411 includes a second waist-shaped hole 4111 and a third waist-shaped hole 4112. The length of the second waist-shaped hole 4111 is greater than the length of the third waist-shaped hole 4112.

[0032] As Figure 4 and Figure 5 shown, among the two groups of mounting holes 411 on any one of the connecting end faces 41, two second waist-shaped holes 4111 and one third waist-shaped hole 4112 can coincide with three round holes 5 adjacent to any side face of the square steel pipe, or one second waist-shaped hole 4111 and two third waist-shaped holes 4112 can coincide with three round holes 5 adjacent to any side face of the square steel pipe. At the coinciding round holes 5, connection can be carried out through bolt assemblies.

[0033] In a preferred embodiment, it is set that the column 2 is connected to the connecting end face 41 through a second bolt assembly 7 and a third bolt assembly 8. The second bolt assembly 7 passes through the round hole 5 and the second waist-shaped hole 4111 of one of the groups of mounting holes 411, and the third bolt assembly 8 passes through the round hole 5 and the third waist-shaped hole 4112 of the same group or another group of mounting holes 411 as above; in a scenario with higher seismic requirements, the second bolt assembly 7 or the third bolt assembly 8 can be set to two, and the total number of the second bolt assembly 7 and the third bolt assembly 8 is three, which can just be inserted into three adjacent round holes 5. The length of the second waist-shaped hole 4111 is set to be greater than the length of the third waist-shaped hole 4112, so that when a bolt assembly can pass through the third waist-shaped hole 4112 of a group of mounting holes 411, another bolt assembly can also be set to pass through the second waist-shaped hole 4111 of this group of mounting holes 411.

[0034] The two right-angle connectors 4 symmetrically distributed on both sides of the column 2 are connected to the column 2 through the same second bolt assembly 7 and third bolt assembly 8. The connection between the column 2 and the right-angle connector 4 is realized in a tensioning manner, which can facilitate the connection between the column 2 and the right-angle connectors 4 symmetrically distributed on both sides of the column 2, and at the same time can improve the connection strength.

[0035] In a preferred embodiment, the horizontal keel 3 is connected to the connecting end face 41 through a fourth bolt assembly 9 and a fifth bolt assembly 10. The fourth bolt assembly 9 passes through the round hole 5 and the second waist-shaped hole 4111 of one of the groups of mounting holes 411, and the fifth bolt assembly 10 passes through the round hole 5 and the third waist-shaped hole 4112 of the same group or another group of mounting holes 411 as above. In a scenario with higher seismic requirements, the fourth bolt assembly 9 or the fifth bolt assembly 10 can be set to two, and the total number of the fourth bolt assembly 9 and the fifth bolt assembly 10 is three, which can just be inserted into three adjacent round holes 5.

[0036] Two right-angle connectors 4 symmetrically distributed on both sides of the horizontal keel 3 are connected to the horizontal keel 3 through the same fourth bolt assembly 9 and fifth bolt assembly 10. The connection between the upright column 2 and the right-angle connector 4 is achieved by a tensioning method, which facilitates the connection of the horizontal keel 3 and the right-angle connectors 4 symmetrically distributed on both sides of the horizontal keel 3, and at the same time can improve the connection strength.

[0037] To facilitate the fixation of the fixing plate 11, a central hole 111 is provided at the center of the fixing plate 11, and four fourth kidney-shaped holes 112 are provided at the four corners of the fixing plate 11. The fixing plate 11 is connected to the wall or the seismic embedded part in the wall through post-expansion anchor bolts passing through the fourth kidney-shaped holes 112 and the central hole 111.

[0038] The above-mentioned first bolt assembly 6, second bolt assembly 7, third bolt assembly, fourth bolt assembly 9, and fifth bolt assembly 10 are all composed of nuts and bolts. The bolts are 8.8-grade M12 high-strength bolts, and the nuts are lock nuts.

[0039] The seismic keel is an assembled structure. Using assembled construction can improve the construction efficiency, and has the advantages of simple structure, low cost, easy implementation, short construction period, and simple construction, and has good application prospects.

[0040] The above description of the installation of the square steel pipe should be regarded as a unified description of the upright column 2 and the horizontal keel 3. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can be made, and these all belong to the protection scope of the present invention.
