Description

Technical Field

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

[0002] Lightweight steel keels and gypsum boards are commonly used for building ceiling decoration. During construction, it is necessary to install the side keels first, then drill holes on the top surface of the building, install the hanging rods, then install the main keels and auxiliary keels, and finally fix the gypsum boards. However, such building ceiling decoration, that is, lightweight steel keels or gypsum boards, cannot bear too much weight.

[0003] In order to avoid making the ceiling too low and causing a sense of oppression, the height of the hanging rod is about 10 cm, so the space between the building top and the gypsum board is very limited. As a result, it is difficult to install a general load-bearing decoration structure in a small space. Therefore, with the emergence of various ceiling decorations, how to enhance the load-bearing capacity of building ceiling decorations has become an urgent problem to be solved.

[0007] The top of described sliding panel also is provided with an interlocking structure, and the interlocking structure is hinged on the base, and the interlocking structure is hinged on the base, and the interlocking structure is hinged on the base, and the interlocking structure is hinged on the base, and the interlocking structure is hinged on the base, and the interlocking structure is hinged on the base, and the interlocking structure is hinged on the base, and the interlocking structure is hinged on the base,

[0008] It also includes a lifting ring for fixing on the top surface of the building, and the lifting ring is used to connect each of the long steel wires and each of the short steel wires.

[0009] As an implementation manner, the number of the suspension springs is four.

[0010] As an embodiment, the column sleeve includes a first column shell and a second column shell connected by a hinge shaft, and the first column shell and the second column shell are provided with an inner ring platform abutting the upper column end face or the lower column end face, and the first column shell and the second column shell are also provided with an outer ring groove for the upper clamping ring or the lower clamping ring to clamp.

[0011] As an embodiment, a step groove is formed between the upper column end face and the upper retaining ring, as well as between the lower column end face and the lower retaining ring, a step edge is formed between the inner ring platform and the outer ring groove of the first column shell, as well as between the inner ring platform and the outer ring groove of the second column shell, and the step edge is engaged with the step groove.

[0012] As an implementation mode, the support rod and the long rod or the short rod are movably connected via a transfer seat.

[0013] As an implementation mode, the upper seat can move slightly along the chain, an arc-shaped steel bar is provided between two adjacent lower seats, and the outer sleeve of the steel bar is provided with a bending spring with two ends respectively abutting against the two lower seats.

[0014] As an embodiment, an upper gripping edge is provided at the upper end of the upper winding turntable.

[0015] As an embodiment, a lower gripping edge is provided at the lower end of the lower winding turntable.

[0016] As an embodiment, a rotating shaft is provided on the lower column, the gear rod is rotatably connected to the rotating shaft, the upper end of the gear rod is provided with an upper inclined surface facing the same direction as the second guide inclined surface, and the lower end of the gear rod is provided with a lower inclined surface facing the same direction as the first guide inclined surface.

[0017] Another technical solution of the present invention is a construction method of a building ceiling decoration structure, characterized in that it comprises the following steps:

[0022] Compared with the prior art, the present invention has the beneficial effect that the building ceiling decoration and decoration structure can increase the bearing capacity of the building ceiling decoration after installation. When installing the building ceiling decoration and decoration structure, the upper parts and the lifting rings need to be fixed to the top surface of the building. The lifting rings are fixed to the edge of the building top surface according to the shape of the building top surface, wherein the long steel wire and the short steel wire can compensate for the distance that the long rod and the short rod cannot reach, and then the upper parts are fixed to the center point of the building top surface. At this time, the upper column and the lower column are connected as a whole by the detachable column sleeve. Then the upper winding turntable and the lower winding turntable are rotated to reel in 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 reeling process, each long rod is synchronously tightened with the corresponding lifting ring, and each short rod is also synchronously tightened with the corresponding lifting ring. Finally, the long rod and the short rod are covered on the top surface of the building by the long steel wire and the short steel wire, and then the column sleeve is removed to separate the upper column and the lower column, wherein the lifting plate is used for the installation of the ceiling decoration. The hoisting plate has nine stress points in total, namely eight lifting rings corresponding to the long steel wires and short steel wires, and one upper mounting part, so the load-bearing capacity of the hoisting plate is doubled. At the same time, because the support rod and the long rod, or the support rod and the short rod are covered on the top surface of the building, the building ceiling decoration structure can be hidden in the very limited space between the top surface of the building and the gypsum board when the short upper and lower columns are made.

DETAILED DESCRIPTION

[0031] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

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

A link 12 is fixed near the top of the upper column 2, and upper seats 13 distributed along the circumferential direction are connected in series on the link 12. The upper seats 13 and the lower seats 11 correspond to each other one by one. A support rod 14 is connected to each upper seat 13, and each support rod 14 is movably connected to a long rod 9 or a short rod 10; an upper winding turntable 15 and a lower winding turntable 16 are provided in the space surrounded by each lower seat 11, and the upper winding turntable 15 and the lower winding turntable 16 are arranged at intervals from top to bottom. 5 is provided with four long steel wires 17 of equal length, each long steel wire 17 passes through the long rod 9 from the inside of the long rod 9 along its length direction, and the lower winding turntable 16 is provided with four short steel wires 18 of equal length, each short steel wire 18 passes through the short rod 10 from the inside of the short rod 10 along its length direction. The upper winding turntable 15 and the lower winding turntable 16 are both rotatably connected to the long rod 9, and an upper toothed platform 19 is provided on the downward side of the upper winding turntable 15, and a plurality of upper clamping teeth 20 distributed circumferentially are provided on the upper toothed platform 19, and each upper clamping tooth 20 is provided with a first guide inclined surface 2 1, a lower gear stand 22 is provided on the upward side of the lower winding turntable 16, and a plurality of lower clamping teeth 23 are provided on the lower gear stand 22, and a second guiding inclined surface 24 is provided on each lower clamping tooth 23, and the first guiding inclined surface 21 and the second guiding inclined surface 24 are in opposite directions. A gear rod 25 is elastically hinged on the lower column 4, and the upper and lower ends of the gear rod 25 extend between the two upper clamping teeth 20 and between the two lower clamping teeth 23 respectively; it also includes a lifting ring 26 for fixing on the top surface of the building, and the lifting ring 26 is used to connect 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. Figure 1As shown, the state of the building ceiling decoration structure before it is covered on the top surface of the building is shown. The long rod 9 and the short rod 10 of the building ceiling decoration structure are forked outward, similar to the shape of the umbrella ribs. During installation, the upper mounting part 1 and the hanging ring 26 need to be fixed to the top surface of the building. The hanging ring 26 is fixed to the edge of the building top surface according to the shape of the building top surface, wherein the long steel wire 17 and the short steel wire 18 can compensate for the distance that the long rod 9 and the short rod 10 cannot reach, and then the upper mounting part 1 is fixed to 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 reel in each long steel wire 17 and each short steel wire 18. Since the four long steel wires 17 are of equal length and the four short steel wires 18 are of equal length, during the reeling 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 rod 9 and the short rod 10 are covered on the top surface of the building by the long steel wire 17 and the short steel wire 18, and then the column sleeve 7 is removed to separate the upper column 2 and the lower column 4, wherein the hanging plate 8 is used for the installation of the ceiling decoration.

[0035] In this embodiment, the hoisting plate 8 has a total of nine stress points, which are eight hanging rings 26 corresponding to the long steel wires 17 and the short steel wires 18, and an upper mounting part 1, so the load-bearing capacity of the hoisting plate 8 is doubled. At the same time, because the support rod 14 and the long rod 9, or the support rod 14 and the short rod 10 are covered on the top surface of the building, the building ceiling decoration structure can be hidden in a very limited space between the top surface of the building and the gypsum board when the short upper column 2 and the lower column 4 are made. Then, during the construction process, the installation of the building ceiling decoration structure should be pre-placed. Then, avoid the hoisting plate 8 and install the side keel around the top surface of the building, punch holes on the top surface of the building to install the hanging rod, and install the main keel and the secondary keel to fix the gypsum board. It should be noted that an opening for installing the customized gypsum board can be reserved at the position directly opposite the hoisting plate 8.

[0036] In one embodiment, Figure 2 shown.

[0037] The building ceiling decoration structure provided in this embodiment has four hanging springs 3 .

[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 position of the upper seat 13 in the circumferential direction can be adjusted, and the position of the lower seat 11 in the circumferential direction can also be adjusted. Therefore, for building top surfaces of different shapes, they can be matched by adjusting the positions of the long rod 9 and the short rod 10.

[0046] In one embodiment, Figure 5 shown.

[0047] In the building ceiling decoration structure provided in this embodiment, an upper gripping edge 37 is provided at the upper end of the upper turntable 15 and a lower gripping edge 38 is provided at the lower end of the lower turntable 16.

[0048] In this embodiment, the upper gripping edge 37 is provided to make the upper turntable 15 easier to rotate, and the lower gripping edge 38 is provided to make the lower gripping edge 38 easier to rotate.

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

[0050] The building ceiling decoration structure provided in this embodiment has a rotating shaft 39 on its lower column 4, and the gear rod 25 is rotatably connected to the rotating shaft 39. The upper end of the gear rod 25 is provided with an upper inclined surface 40 facing the same direction as the second guide inclined surface 24, and the lower end of the gear rod 25 is provided with a lower inclined surface 41 facing the same direction as the first guide inclined surface 21.

[0051] In this embodiment, a gear rod 25 is provided between the upper gear stage 19 and the lower gear stage 22, and the gear rod 25 is elastically hinged on the rotating shaft 39, so that the upper winding turntable 15 and the lower winding turntable 16 can only rotate in one direction. Figure 6 It can be seen that the gear rod 25 is moved clockwise by the elastic force, and when the upper winding turntable 15 rotates, each time an upper tooth 20 passes through the gear rod 25, the end of the gear rod 25 automatically falls between the other two upper teeth 20. Similarly, the rotation of the lower winding turntable 16 is the same. The only difference is that the rotation directions of the upper winding turntable 15 and the lower winding turntable 16 are opposite. Due to the elastic hinge characteristics of the gear rod 25, the upper winding turntable 15 and the lower winding turntable 16 are interlocked by the gear rod 25 after being tightened.

[0052] In one embodiment, the construction method of the building ceiling decoration structure includes the following steps: a first step, fixing the lifting ring on the building top surface according to the shape of the building top surface, connecting the long steel wire and the short steel wire to the corresponding lifting ring respectively, determining the center point according to the position of each lifting ring on the building top surface, and fixing the upper mounting part at the center point of the building top surface; a second step, synchronously rotating the upper winding turntable and the lower winding turntable in opposite directions to reel in the long steel wire and the short steel wire respectively; a third step, removing the column sleeve; a fourth step, installing side keels around the building top surface, drilling holes on the building top surface to install hanging rods, installing the main keel and the auxiliary keel avoiding the center point of the building top surface, and then fixing the gypsum board.

[0053] In this embodiment, the use of a building ceiling decoration structure can increase the load-bearing capacity of the building ceiling decoration after installation. The long rod 9 and the short rod 10 of the building ceiling decoration structure are forked outward, similar to the shape of an umbrella rib. During installation, the upper mounting 1 and the ring 26 need to be fixed to the top surface of the building. The ring 26 is fixed to the edge of the top surface of the building according to the shape of the top surface of the building, wherein the long steel wire 17 and the short steel wire 18 can compensate for the distance that the long rod 9 and the short rod 10 cannot reach, and then the upper mounting 1 is fixed to the center point of the top surface of the building. 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 reel in each long steel wire 17 and each short steel wire 18. Since the four long steel wires 17 are of equal length and the four short steel wires 18 are of equal length, during the reeling process, each long rod 9 is synchronously tightened with the corresponding ring 26, and each short rod 10 is also synchronously tightened with the corresponding ring 26. Finally, the long rod 9 and the short rod 10 are covered on the top surface of the building by the long steel wire 17 and the short steel wire 18, and then the column sleeve 7 is disassembled to separate the upper column 2 and the lower column 4, wherein the hanging plate 8 is used for the installation of the ceiling decoration. The hanging plate 8 has a total of nine stress points, which are eight hanging rings 26 corresponding to the long steel wire 17 and the short steel wire 18, and an upper mounting part 1, so the load-bearing capacity of the hanging plate 8 is doubled. At the same time, because the supporting rod 14 and the long rod 9, or the supporting rod 14 and the short rod 10 are covered on the top surface of the building, the decoration structure of the building ceiling can be hidden in a very limited space between the top surface of the building and the gypsum board when the short upper column 2 and the lower column 4 are made. Then, during the construction process, the installation of the building ceiling decoration structure should be pre-placed. Then avoid the hanging plate 8 to install the side keel around the top surface of the building, punch holes on the top surface of the building to install the hanging rod, and install the main keel and the auxiliary keel to fix the gypsum board. The construction method of the building ceiling decoration adds a step of installing the building ceiling decoration structure before the fourth step of the traditional construction method.

[0054] The specific implementation methods described above further describe the invention purpose, technical solutions, and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the protection scope of the present invention. It is particularly pointed out that for those skilled in the art, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
