Description

Technical Field

[0001] The present invention relates to the technical field of suspended ceilings, and particularly relates to a building suspended ceiling decoration structure and a construction method thereof. Background Art

[0002] In building suspended ceiling decoration, light steel keels and gypsum boards are relatively commonly used. During construction, it is necessary to first install the edge keel, then drill holes in the building top surface, install the hanging bars, then install the main keel and the secondary keel, and finally fix the gypsum board. However, for such building suspended ceiling decoration, neither the light steel keel nor the gypsum board can bear too much weight.

[0003] In order not to make the suspended ceiling surface too low and bring a sense of depression, the lowering height of the hanging bars is about 10 cm. Therefore, the space between the building top surface and the gypsum board is very limited. As a result, it is very difficult to install a general-purpose load-bearing decoration structure in a narrow space. For this reason, with the emergence of various suspended ceiling decorations, how to enhance the load-bearing capacity of building suspended ceiling decoration has become an urgent problem to be solved. Summary of the Invention

[0004] The present invention aims to solve the above technical problems and provides a building suspended ceiling decoration structure and a construction method thereof.

[0005] One technical solution of the present invention is a building suspended ceiling decoration structure, including an upper mounting member for fixing on the building top surface. A upper column is provided at the bottom of the upper mounting member. A lower column is connected below the upper column through a suspension spring. An upper snap ring is provided at a position near the bottom of the upper column. A lower snap ring is provided at a position near the top of the lower column. A detachable column sleeve is connected between the upper snap ring and the lower snap ring;

[0006] A hoisting disc is provided at the bottom of the lower column. Four long rods are provided at a position near the bottom of the lower column and are evenly distributed along the circumferential direction. A short rod is provided between each adjacent two long rods. Lower seats are provided at the ends of each long rod and each short rod surrounding the circumference of the lower column. A connecting ring is fixed at a position near the top of the upper column. Upper seats distributed along the circumferential direction are strung on the connecting ring. The upper seats and the lower seats correspond one by one. A support rod is connected to each upper seat. Each support rod is movably connected to one of the long rods or one of the short rods;

[0007] Inside the space surrounded by each of the lower seats, there are an upper rotating turntable and a lower rotating turntable spaced vertically. There are four equally long long steel wires on the upper rotating turntable. Each of the long steel wires passes through the long rod along its length direction from the inside of the long rod. There are four equally long short steel wires on the lower rotating turntable. Each of the short steel wires passes through the short rod along its length direction from the inside of the short rod. Both the upper rotating turntable and the lower rotating turntable are rotatably connected to the long rod. On the downward side of the upper rotating turntable, there is an upper tooth platform. There are several upper engaging teeth distributed circumferentially on the upper tooth platform. Each of the upper engaging teeth is provided with a first guiding inclined surface. On the upward side of the lower rotating turntable, there is a lower tooth platform. There are several lower engaging teeth distributed circumferentially on the lower tooth platform. Each of the lower engaging teeth is provided with a second guiding inclined surface. The orientations of the first guiding inclined surface and the second guiding inclined surface are opposite. A toothed rod is also elastically hinged on the lower column. The upper and lower ends of the toothed rod extend into the spaces between two of the upper engaging teeth and between two of the lower engaging teeth respectively;

[0008] It also includes a lifting ring for being fixed on the top surface of a building. The lifting ring is for connecting each of the long steel wires and each of the short steel wires.

[0009] As an implementation manner, the suspension springs are provided in four numbers.

[0010] As an implementation manner, the column sleeve includes a first column shell and a second column shell connected by a hinge shaft. There is an inner ring platform in the first column shell and the second column shell for abutting against the upper end face of the upper column or the lower end face of the lower column. There is also an outer ring groove in the first column shell and the second column shell for clamping the upper snap ring or the lower snap ring.

[0011] As an implementation manner, a stepped groove is formed between the upper end face of the upper column and the upper snap ring, and between the lower end face of the lower column and the lower snap ring. A stepped edge is formed between the inner ring platform and the outer ring groove of the first column shell, and between the inner ring platform and the outer ring groove of the second column shell. The stepped edge and the stepped groove are engaged.

[0012] As an implementation manner, the support rod and the long rod or the short rod are movably connected through an adapter seat.

[0013] As an implementation manner, the upper seat can move slightly along the connecting ring. There is an arc-shaped steel bar between two adjacent lower seats. A bending spring with both ends respectively abutting against the two lower seats is sleeved outside the steel bar.

[0014] As an implementation manner, the upper end of the upper rotating turntable is provided with an upper gripping edge.

[0015] As an implementation manner, the lower end of the lower rotating turntable is provided with a lower gripping edge.

[0016] As an implementation manner, a rotating shaft is provided on the lower column, the toothed rod is rotatably connected to the rotating shaft, an upper inclined surface with the same orientation as the second guiding inclined surface is provided at the upper end of the toothed rod, and a lower inclined surface with the same orientation as the first guiding inclined surface is provided at the lower end of the toothed rod.

[0017] Another technical solution of the present invention is a construction method for a building ceiling decoration structure, which is characterized by including the following steps

[0018] The first step is to fix the hanging rings on the building top surface according to the shape of the building top surface, connect the long steel wires and the short steel wires to the corresponding hanging rings respectively, determine the center point according to the positions of the hanging rings on the building top surface, and fix the upper mounting part at the center point of the building top surface;

[0019] The second step is to synchronously rotate the upper winding turntable and the lower winding turntable in opposite directions to wind up the long steel wire and the short steel wire respectively;

[0020] The third step is to disassemble the column sleeve;

[0021] The fourth step is to install the edge keel around the building top surface, drill holes in the building top surface to install the hanging bars, install the main keel and the auxiliary keel avoiding the center point position of the building top surface, and then fix the gypsum board.

[0022] The beneficial effect of the present invention compared with the prior art is that the bearing capacity of the building ceiling decoration can be increased after the installation of this building ceiling decoration structure. When installing this building ceiling decoration structure, the upper mounting part and the hanging rings need to be fixed to the building top surface. The hanging rings are fixed on the edge of the building top surface according to the shape of the building top surface. The long steel wire and the short steel wire can compensate for the distances that the long rod and the short rod cannot reach, and then the upper mounting part is fixed at the center point of the building top surface. At this time, the upper column and the lower column are connected as a whole by a detachable column sleeve. Then rotate the upper winding turntable and the lower winding turntable to wind up each long steel wire and each short steel wire. Since the four long steel wires are of equal length and the four short steel wires are of equal length, during the winding process, each long rod is synchronously tightened with the corresponding hanging ring, and each short rod is also synchronously tightened with the corresponding hanging ring. Finally, the long rod and the short rod are covered on the building top surface by means of the long steel wire and the short steel wire. Then disassemble the column sleeve to separate the upper column and the lower column. The hoisting plate is used for the installation of the ceiling decoration. There are a total of nine stress points on the hoisting plate, namely the eight hanging rings corresponding to the long steel wire and the short steel wire, and an upper mounting part. Therefore, the bearing capacity of this hoisting plate is doubled. At the same time, since it is covered on the building top surface through the support rod and the long rod, or the support rod and the short rod, in the case of short upper column and lower column, this building ceiling decoration structure can be hidden in the very limited space between the building top surface and the gypsum board.

Specific Embodiments

[0031] The following will clearly and completely describe the above and other embodiments and advantages of the present invention with reference to the accompanying drawings. Obviously, the described embodiments are only partial embodiments of the present invention, rather than all embodiments.

[0032] In one embodiment, as Figures 1 to 6 shown.

[0033] The building ceiling decoration structure provided by this embodiment includes an upper mounting member 1 for fixing on the building top surface. A upper column 2 is provided at the bottom of the upper mounting member 1. A lower column 4 is connected to the lower part of the upper column 2 through a suspension spring 3. An upper clamping ring 5 is provided at a position near the bottom of the upper column 2. A lower clamping ring 6 is provided at a position near the top of the lower column 4. A detachable column sleeve 7 is connected between the upper clamping ring 5 and the lower clamping ring 6; A hoisting disc 8 is provided at the bottom of the lower column 4. Four long rods 9 evenly distributed along the circumferential direction are provided at a position near the bottom of the lower column 4. A short rod 10 is provided between each adjacent two long rods 9. Lower seats 11 are provided at the ends of each long rod 9 and each short rod 10 around the circumference of the lower column 4. A connecting ring 12 is fixed at a position near the top of the upper column 2. Upper seats 13 distributed along the circumferential direction are strung on the connecting ring 12. The upper seats 13 and the lower seats 11 correspond one by one. A support rod 14 is connected to each upper seat 13. Each support rod 14 is movably connected to a long rod 9 or a short rod 10; An upper rotating disc 15 and a lower rotating disc 16 are provided at intervals up and down within the space surrounded by each lower seat 11. Four equal-length long steel wires 17 are provided on the upper rotating disc 15. Each long steel wire 17 passes through the long rod 9 along its length direction from the inside of the long rod 9. Four equal-length short steel wires 18 are provided on the lower rotating disc 16. Each short steel wire 18 passes through the short rod 10 along its length direction from the inside of the short rod 10. The upper rotating disc 15 and the lower rotating disc 16 are both rotatably connected to the long rod 9. An upper tooth platform 19 is provided on the downward side of the upper rotating disc 15. A number of upper clamping teeth 20 distributed in a circle are provided on the upper tooth platform 19. A first guiding inclined surface 21 is provided on each upper clamping tooth 20. A lower tooth platform 22 is provided on the upward side of the lower rotating disc 16. A number of lower clamping teeth 23 distributed in a circle are provided on the lower tooth platform 22. A second guiding inclined surface 24 is provided on each lower clamping tooth 23. The first guiding inclined surface 21 and the second guiding inclined surface 24 face in opposite directions. A toothed rod 25 is also elastically hinged on the lower column 4. The upper and lower ends of the toothed rod 25 respectively extend between two upper clamping teeth 20 and between two lower clamping teeth 23; It further includes a suspension ring 26 for fixing on the building top surface. The suspension ring 26 is for connecting each long steel wire 17 and each short steel wire 18.

[0034] In this embodiment, the building ceiling decoration structure can increase the load-bearing capacity of the building ceiling decoration after installation. For example Figure 1As shown, the state of the building ceiling decoration structure before being covered on the building top surface is shown. The long rods 9 and short rods 10 of the building ceiling decoration structure diverge outward, similar to the shape of an umbrella rib. During installation, the upper mounting part 1 and the suspension rings 26 need to be fixed to the building top surface. The suspension rings 26 are fixed at the edge of the building top surface according to the shape of the building top surface, where the long steel wires 17 and short steel wires 18 can compensate for the distances that the long rods 9 and short rods 10 cannot reach, and then the upper mounting part 1 is fixed at the center point of the building top surface. At this time, the upper column 2 and the lower column 4 are connected as a whole by the detachable column sleeve 7. Then, the upper winding turntable 15 and the lower winding turntable 16 are rotated to wind up the long steel wires 17 and the short steel wires 18 respectively. Since the four long steel wires 17 are of equal length and the four short steel wires 18 are of equal length, during the winding process, each long rod 9 is synchronously tightened with the corresponding suspension ring 26, and each short rod 10 is also synchronously tightened with the corresponding suspension ring 26. Finally, the long rods 9 and short rods 10 are covered on the building top surface by means of the long steel wires 17 and short steel wires 18, and then the column sleeve 7 is disassembled to separate the upper column 2 and the lower column 4, where the hoisting disc 8 is used for the installation of the ceiling decoration.

[0035] In this embodiment, the hoisting disc 8 has a total of nine stress points, namely the eight suspension rings 26 corresponding to the long steel wires 17 and short steel wires 18, and one upper mounting part 1. Therefore, the load-bearing capacity of the hoisting disc 8 is doubled. At the same time, since it is covered on the building top surface through the support rods 14 and the long rods 9, or the support rods 14 and the short rods 10, in the case of the short upper column 2 and the lower column 4, the building ceiling decoration structure can be hidden in the very limited space between the building top surface and the gypsum board. Then, during the construction process, the installation of the building ceiling decoration structure needs to be advanced. Then, avoid the hoisting disc 8 and install the edge keel around the building top surface, drill holes in the building top surface to install the suspender bars, and install the main keel and the secondary keel, and fix the gypsum board. It should be noted that an opening for installing the customized gypsum board is reserved at the position directly opposite to the hoisting disc 8.

[0036] In one embodiment, as Figure 2 shown.

[0037] For the building ceiling decoration structure provided in this embodiment, the suspension springs 3 are set to four.

[0038] In this embodiment, the upper column 2 and the lower column 4 are connected by four hanging springs 3. After the column sleeve 7 is removed, the rigid connection between the upper column 2 and the lower column 4 is released, and the connection strength of the building ceiling decoration structure is enhanced after the hanging plate 8 bears the weight. If the hanging plate 8 bears the weight, the upper column 2 pulls the hanging plate 8 on the lower column 4 through the hanging spring 3, and the long rod 9 and the short rod 10 also pull the hanging plate 8, and the force can be divided into nine force points. After the column sleeve 7 is removed, the hanging plate 8 has a downward trend. Because the long rod 9 or the short rod 10 is fixed at two points, it can resist the downward movement of the hanging plate 8. Compared with the rigid connection, it is obviously more capable of dividing the force to eight force points other than the center point.

[0039] In one embodiment, Figure 2 and Figure 7 shown.

[0040] The architectural ceiling decoration structure provided in this embodiment includes a column sleeve 7 comprising a first column shell 28 and a second column shell 29 connected by a hinge shaft 27, wherein an inner ring platform 30 is provided in the first column shell 28 and the second column shell 29 to abut against the end face of the upper column 2 or the end face of the lower column 4, and an outer ring groove 31 for the upper clamping ring 5 or the lower clamping ring 6 is also provided in the first column shell 28 and the second column shell 29. A step groove 32 is formed between the end face of the upper column 2 and the upper clamping ring 5, and between the end face of the lower column 4 and the lower clamping ring 6, and a step edge 33 is formed between the inner ring platform 30 and the outer ring groove 31 of the first column shell 28, and between the inner ring platform 30 and the outer ring groove 31 of the second column shell 29, and the step edge 33 is engaged with the step groove 32.

[0041] In this embodiment, the rigid connection between the upper column 2 and the lower column 4 can be released by opening the first column shell 28 and the second column shell 29. In order to enhance the connection strength of the rigid connection, an inner ring platform 30 is provided in the first column shell 28 and the second column shell 29, an outer ring groove 31 is provided in the first column shell 28 and the second column shell 29, and a step groove 32 and a step edge 33 are also provided. Thus, various patterns are engaged respectively.

[0042] In one embodiment, the support rod 14 and the long rod 9 or the short rod 10 of the building ceiling decoration structure are movably connected via an adapter 34 .

[0043] In one embodiment, Figure 3 and Figure 4 shown.

[0044] The building ceiling decoration structure provided in this embodiment has an upper seat 13 that can move slightly along the chain 12, an arc-shaped steel bar 35 is provided between two adjacent lower seats 11, and a bending spring 36 is provided on the outer sleeve of the steel bar 35, with two ends respectively contacting the two lower seats 11.

[0045] In this embodiment, the upper seat 13 can be adjusted in the circumferential direction, and the lower seat 11 can also be adjusted in the circumferential direction. Therefore, for building top surfaces of different shapes, the positions of the long rod 9 and the short rod 10 can be adjusted to make a match.

[0046] In one embodiment, as Figure 5 shown.

[0047] For the building ceiling decoration structure provided in this embodiment, an upper holding edge 37 is provided at the upper end around the turntable 15. A lower holding edge 38 is provided at the lower end around the turntable 16.

[0048] In this embodiment, by providing the upper holding edge 37, the rotation of the upper turntable 15 becomes easier, and by providing the lower holding edge 38, the rotation of the lower holding edge 38 becomes easier.

[0049] In one embodiment, as Figure 5 and Figure 6 shown.

[0050] For the building ceiling decoration structure provided in this embodiment, a rotating shaft 39 is provided on the lower column 4, the toothed rod 25 is rotatably connected to the rotating shaft 39, an upper inclined surface 40 with the same orientation as the second guiding inclined surface 24 is provided at the upper end of the toothed rod 25, and a lower inclined surface 41 with the same orientation as the first guiding inclined surface 21 is provided at the lower end of the toothed rod 25.

[0051] In this embodiment, by providing the toothed rod 25 between the upper tooth platform 19 and the lower tooth platform 22, and the toothed rod 25 is elastically hinged to the rotating shaft 39, the upper turntable 15 and the lower turntable 16 can only rotate in one direction. To Figure 6 illustrate, the toothed rod 25 tends to rotate clockwise under the action of elastic force. During the rotation of the upper turntable 15, every time an upper tooth 20 passes by the toothed rod 25, the end of the toothed rod 25 automatically falls between the other two upper teeth 20. Similarly, the rotation of the lower turntable 16 is the same. Only the rotation directions of the upper turntable 15 and the lower turntable 16 are opposite. Due to the elastically hinged characteristic of the toothed rod 25, the upper turntable 15 and the lower turntable 16 are interlocked by means of the toothed rod 25 after being tightened.

[0052] In one embodiment, the construction method of the building ceiling decoration structure includes the following steps. First step, fix the hanging rings on the building top surface according to the shape of the building top surface, connect the long steel wires and the short steel wires to the corresponding hanging rings respectively, determine the center point according to the positions of the hanging rings on the building top surface, and fix the upper mounting part on the center point of the building top surface. Second step, synchronously rotate the upper winding turntable and the lower winding turntable in opposite directions to wind up the long steel wire and the short steel wire respectively. Third step, disassemble the column sleeve. Fourth step, install the edge keel around the building top surface, drill holes in the building top surface to install the hanger bars, install the main keel and the auxiliary keel while avoiding the center point position of the building top surface, and then fix the gypsum board.

[0053] In this embodiment, the use of the building ceiling decoration structure can increase the load-bearing capacity of the building ceiling decoration after installation. The long rods 9 and the short rods 10 of the building ceiling decoration structure diverge outwards, similar to the shape of an umbrella rib. During installation, the upper mounting part 1 and the hanging rings 26 need to be fixed to the building top surface. Fix the hanging rings 26 on the edge of the building top surface according to the shape of the building top surface. The long steel wires 17 and the short steel wires 18 can compensate for the distances that the long rods 9 and the short rods 10 cannot reach, and then fix the upper mounting part 1 at the center point of the building top surface. At this time, the upper column 2 and the lower column 4 are integrated by the detachable column sleeve 7. Then rotate the upper winding turntable 15 and the lower winding turntable 16 to wind up the long steel wires 17 and the short steel wires 18 respectively. Since the four long steel wires 17 are of equal length and the four short steel wires 18 are of equal length, during the winding process, each long rod 9 is synchronously tightened with the corresponding hanging ring 26, and each short rod 10 is also synchronously tightened with the corresponding hanging ring 26. Finally, the long rods 9 and the short rods 10 are covered on the building top surface by means of the long steel wires 17 and the short steel wires 18. Then disassemble the column sleeve 7 to separate the upper column 2 and the lower column 4. The hoisting disc 8 is used for the installation of the ceiling decoration. There are a total of nine stress points on the hoisting disc 8, namely the eight hanging rings 26 corresponding to the long steel wires 17 and the short steel wires 18, and one upper mounting part 1. Therefore, the load-bearing capacity of the hoisting disc 8 is doubled. At the same time, since it is covered on the building top surface through the support rods 14 and the long rods 9, or the support rods 14 and the short rods 10, in the case of the short upper column 2 and the lower column 4, the building ceiling decoration structure can be hidden in the very limited space between the building top surface and the gypsum board. Then, during the construction process, the installation of the building ceiling decoration structure needs to be advanced. Then install the edge keel around the building top surface while avoiding the hoisting disc 8, drill holes in the building top surface to install the hanger bars, and install the main keel and the auxiliary keel, and fix the gypsum board. The construction method of this building ceiling decoration adds the step of installing the building ceiling decoration structure before the fourth step of the traditional construction method.
