Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated interior decoration, and in particular to a square-shaped top surface structure of a prefabricated lobby with a hollow high-rise space. Background Art

[0002] When decorating the ceiling of a high, hollow space in an indoor lobby, metal panels are typically suspended using hanging rods to form the ceiling. For example, Chinese patent CN203361434U discloses a large-scale, thin-walled metal panel ceiling structure, comprising thin-walled metal panels, a light steel frame structure, hanging brackets, and bent hooking brackets. Adjacent side portions of the thin-walled metal panels are connected to the bent hooking brackets via the hooking brackets, while the remaining side portions and the center portion are connected to the light steel frame structure via hanging brackets. The light steel frame structure is fixedly connected to the building's supporting surface.

[0003] The ceiling structure formed by hanging metal plates is difficult to control the joints and flatness during the installation of the decorative surface, and repeated adjustments are required during the installation process. The high ceiling space puts people at high altitudes during the ceiling construction, and the installation process is cumbersome and time-consuming, resulting in high safety risks and an increased chance of safety accidents. On the other hand, the threaded hangers for hanging metal plates are prone to being too long and easily bent and deformed, causing deformation of the ceiling structure. Summary of the Invention

[0004] The purpose of the present invention is to provide a prefabricated design lobby with a hollow high-rise space and a square tube-shaped ceiling structure, which uses prefabricated square tube components for ceiling decoration, reduces the installation steps, does not require debugging, effectively reduces the time for construction workers to work at height, and reduces safety risks.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an assembled design lobby hollow high space square tube shape top surface structure, comprising:

[0006] A steel frame transfer layer, comprising a plurality of support frame units arranged in an array, wherein the support frame units include a central column, a support plate and a transverse support rod. The central column is fixedly mounted on the top surface of the building. The central column is a rectangular column. The support plate is arranged at the bottom of the central column. The support plate is in the shape of a cross. A plurality of support plate units extending from the side of the central column are arranged on the support plate. One support plate unit corresponds to one side of the central column. Transverse support rods and locking plates are respectively arranged on the support plate units on opposite sides of the support plate. The transverse support rods are hinged on the support plate. The transverse support rods of one support frame unit are fixedly mounted on the locking plate of another adjacent support frame unit.

[0007] A prefabricated square tube assembly includes a hanging keel, a hanging part and a square tube part. The cross-section of the hanging keel is "C"-shaped. Several hanging plates are provided on the back of the hanging keel. The transverse support rod is provided with a hanging groove whose position corresponds to the hanging plate. A plurality of notches are provided on the lower side plate of the hanging keel. The plurality of notches are arranged in sequence along the length direction of the hanging keel. The hanging part includes a base plate, a threaded rod and a locking nut. The base plate is slidably connected to the slide groove on the top surface of the square tube part. The threaded rod is fixedly installed on the base plate. The threaded rod is clamped in the notch. The end of the threaded rod is extended into the inner side of the hanging keel and fixed by a locking nut.

[0008] As a further description of the above technical solution:

[0009] A pre-embedded threaded rod is provided on the top surface of the building, and the central column is threadedly connected to the pre-embedded threaded rod.

[0010] As a further description of the above technical solution:

[0011] A threaded hole is provided in the center column, the threaded hole is arranged along the length direction of the center column, and the embedded threaded rod is threadedly connected in the threaded hole.

[0012] As a further description of the above technical solution:

[0013] The supporting plate is fixedly mounted on the central column by means of bolts, and the rod of the bolt passes through the supporting plate and is threadedly connected in the threaded hole.

[0014] As a further description of the above technical solution:

[0015] A clamping groove is provided at the end of the transverse support rod, the locking plate is clamped in the clamping groove, and the transverse support rod is fixed on the locking plate by screws.

[0016] As a further description of the above technical solution:

[0017] The width of the slot opening is equal to the thickness of the locking plate.

[0018] As a further description of the above technical solution:

[0019] The end of the hanging keel rests on the supporting plate unit.

[0020] As a further description of the above technical solution:

[0021] An auxiliary connecting seat is provided at the end of the transverse supporting rod. The auxiliary connecting seat is rotatably mounted on the transverse supporting rod, and the auxiliary connecting seat is fixedly mounted on the top surface of the building.

[0022] As a further description of the above technical solution:

[0023] The mounting plates and hanging parts are arranged at intervals.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In this invention, when using prefabricated square tube components for ceiling decoration, a steel frame transfer layer is added to replace the hanging rods, thereby lowering the ceiling height. The prefabricated square tube components are directly installed on the steel frame transfer layer. The steel frame transfer layer is not easily deformed, and the use of square tubes instead of metal plates for ceiling decoration effectively prevents ceiling deformation.

[0026] 2. In the present invention, the prefabricated square tube assembly includes several parallel mounting keels. Multiple square tube components are pre-assembled on the ground with the mounting keels using hanging components. Therefore, when the top decorative layer of the square tube structure needs to be installed, it is only necessary to mount and secure the multiple prefabricated square tube components to the transverse support rods of the steel frame transfer layer. This reduces the number of installation steps and the need for commissioning, effectively shortening the time construction workers spend working at height and reducing safety risks. When the prefabricated square tube components are mounted on the transverse support rods, the arrangement of the square tube components can be flexibly adjusted by mounting them on transverse support rods with different orientations, making installation more flexible.

All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0040] See also Figure 1-8 The present invention provides a technical solution: a prefabricated design lobby hollow high space square tube shape top surface structure, comprising:

[0041] A steel frame transfer layer, which includes a plurality of support frame units 1 arranged in an array, the support frame unit 1 including a central column 11, a supporting plate 12 and a transverse support rod 13, the central column 11 is fixedly installed on the top surface of the building, the central column 11 is a rectangular column, the supporting plate 12 is arranged at the bottom of the central column 11, the supporting plate 12 is in a "cross" shape, and a plurality of supporting plate units 121 extending from the side of the central column 11 are provided on the supporting plate 12, one supporting plate unit 121 corresponds to one side of the central column 11, and a transverse support rod 13 and a locking plate 122 are respectively provided on the supporting plate unit 121 on the opposite side of the supporting plate 12, the transverse support rod 13 is hinged on the supporting plate 12, and the transverse support rod 13 of one support frame unit 1 is fixedly installed on the locking plate 122 of another adjacent support frame unit 1;

[0042] The prefabricated square tube component 2 includes a hanging keel 21, a hanging part 22 and a square tube part 23. The cross-section of the hanging keel 21 is "C"-shaped. Several hanging plates 211 are provided on the back of the hanging keel 21. The transverse support rod 13 is provided with a hanging groove 131 whose position corresponds to the hanging plate 211. A plurality of notches 212 are provided on the lower side plate of the hanging keel 21. The plurality of notches 212 are arranged in sequence along the length direction of the hanging keel 21. The hanging part 22 includes a base plate 221, a threaded rod 222 and a locking nut 223. The base plate 221 is slidably connected to the slide groove 231 on the top surface of the square tube part 23, and the threaded rod 222 is fixedly installed on the base plate 221. The threaded rod 222 is clamped in the notch 212. The end of the threaded rod 222 is extended into the inner side of the hanging keel 21 and is fixed by the locking nut 223.

[0043] An embedded threaded rod 14 is provided on the top surface of the building, and the central column 11 is threadedly connected to the embedded threaded rod 14, so that the installation height of the supporting plate 12 at the bottom of the support frame unit 1 can be flexibly adjusted to achieve top surface leveling.

[0044] A threaded hole 111 is provided in the center column 11 and arranged along the length of the center column 11. A pre-embedded threaded rod 14 is threadedly connected to the threaded hole 111. The support plate 12 is fixedly mounted on the center column 11 by bolts 15. The rod of the bolt 15 passes through the support plate 12 and is threadedly connected to the threaded hole 111, making it easy to remove and replace the support plate 12. The support plate 12 and the center column 11 are designed to be separated, which facilitates the installation and removal of the support frame unit 1. When inspecting pipes or equipment in a local area of ​​the building roof, it is not necessary to completely disassemble the support frame unit 1. The support plate 12 can be removed for easy maintenance.

[0045] The end of the transverse support rod 13 is provided with a slot 132, into which the locking plate 122 is engaged. The transverse support rod 13 is fixed to the locking plate 122 by screws. The width of the slot 132 opening is equal to the thickness of the locking plate 122. The locking plate 122 effectively positions the transverse support rod 13 and prevents the transverse support rod 13 from shifting.

[0046] The end of the hanging keel 21 is against the supporting plate unit 121, and the supporting plate 12 of the support frame unit 1 is used to position the prefabricated square tube component 2 to prevent the prefabricated square tube component 2 from positional deviation and avoid deformation of the top surface.

[0047] Auxiliary connecting seats 16 are provided at the ends of the transverse support rods 13. Auxiliary connecting seats 16 are rotatably mounted on the transverse support rods 13 and are fixedly mounted on the roof of the building. For support frame units 1 at the edge of the steel frame transfer layer, if there are no support frame units 1 on the side thereof to which the transverse support rods 13 can be fixed, auxiliary connecting seats 16 can be provided at the ends of the transverse support rods 13 and fixedly mounted on the roof of the building. This allows the transverse support rods 13 to form the oblique support rods of the support frame units 1, thereby improving the installation security of the steel frame transfer layer and preventing deformation and settlement of the steel frame transfer layer.

[0048] The hanging plates 211 and the hanging members 22 are arranged at intervals, which effectively improves the hanging stability of the prefabricated square tube assembly 2.

[0049] Working principle: When installing the steel frame transfer layer, first lay out the lines and position them on the top surface of the building to determine the installation positions of several support frame units 1, and then fix several support frame units 1 on the top surface of the building in sequence. Since two transverse support rods 13 are provided on the adjacent two sides of a right angle on the central column 11 of the support frame unit 1, and two locking plates 122 are provided on the adjacent two sides of the opposite right angle, the transverse support rod 13 of one support frame unit 1 is fixedly installed on the locking plate 122 of another adjacent support frame unit 1. One support frame unit 1 is fixedly installed on two adjacent support frame units 1 through two transverse support rods 13. Several transverse support rods 13 form a grid-like transfer layer hanging frame for hanging prefabricated square tube components 2. The two ends of the transverse support rods 13 are supported by support plates 12. When using prefabricated square tube components 2 for top surface decoration, a steel frame transfer layer is added to replace the hanging rods (i.e., threaded hanging rods), thereby reducing the top surface height, and the prefabricated square tube components 2 are directly installed on the steel frame transfer layer. The steel frame transfer layer is not easy to deform, and square tubes are used instead of metal plates for top surface decoration, effectively avoiding top surface deformation.

[0050] The prefabricated square tube assembly 2 includes several parallel-arranged mounting keels 21. The embodiment illustrated in the accompanying drawings in this specification specifically includes two mounting keels 21. Multiple square tube components 23 are pre-assembled on the ground with the mounting keels 21 via hangers 22. This allows for the installation of the top decorative layer of the square tube structure by simply mounting and securing the multiple prefabricated square tube components 2 to the transverse support rods 13 of the steel frame transition layer. This reduces the number of installation steps and eliminates the need for commissioning, effectively reducing the time construction workers spend working at height and lowering safety risks. When the prefabricated square tube components 2 are mounted on the transverse support rods 13, the arrangement of the square tube components 23 can be flexibly adjusted by mounting them on transverse support rods 13 in different orientations, making installation more flexible.

[0051] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
