[0002] In the field of construction engineering, steel grid structures are widely used in various construction projects such as stadiums, libraries, exhibition halls, and other large-span public venues. The interior decoration design of such large venues often adopts a variety of forms and technologies to create unique visual effects. The ceiling decoration surface covering the bottom of the spatial structure grid in the building structure usually covers a large flat area due to the spatial characteristics of the grid. The ceiling at the bottom of the grid is usually irregular in shape to achieve a decorative effect that adds a unique artistic sense and personalized elements to the space. However, the existing grid structure is subjected to the force of the grid ball point, and its rods are strictly prohibited from secondary welding, drilling, and cutting. Therefore, the ceiling hanger at the bottom of the grid cannot be directly connected to the grid structure. This affects the construction of the ceiling installed on the roof of the steel grid structure with grid ball points, and the safety and accuracy of the ceiling installation cannot be guaranteed.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] like Figure 1-4 As shown, the present invention solves the problem in the prior art that the rods of the grid ball point are strictly prohibited from secondary welding, punching and cutting, which results in the inability to directly connect the grid bottom ceiling hanger to the grid structure. The present invention provides the following technical solutions: a grid bottom ceiling conversion structure, comprising a grid ball node 1, the lower end of the grid ball node 1 is vertically connected to a steel pipe 4, a support plate 5 is installed at the bottom of the steel pipe 4, a plurality of conversion layer keels 8 facing the middle of the support plate 5 are horizontally arranged around the bottom of the support plate 5, the end of the conversion layer keel 8 is provided with a sealing plate 11, and the end surface of the sealing plate 11 extends outward. A transfer layer keel vertical connecting plate 9 is provided, and the lower end of the support plate 5 is connected to a supporting vertical connecting plate 6 that corresponds one to one with the transfer layer keel vertical connecting plate 9. The transfer layer keel vertical connecting plate 9 is connected to the corresponding supporting vertical connecting plate 6 by fasteners. A ceiling assembly is provided on the lower side of the transfer layer keel 8. A transfer connection structure is formed by arranging the supporting vertical connecting plate 6, the transfer layer keel vertical connecting plate 9 and the transfer layer keel 8, so that the grid ball node 1 does not need to be welded or cut for the second time, thereby realizing a firm connection between the ceiling and the grid structure and meeting the requirements of the design and decorative effects.

[0020] Specifically, the steel pipe 4 is a round steel pipe, and its upper end can fit into the grid ball node 1 after contact. There is no need for welding between the two, and fasteners can be used to connect them. Specifically, a perforated plate 3 is installed on the upper inner part of the steel pipe 4, and a ball joint connecting screw 2 connected to the grid ball node 1 is passed through the middle of the perforated plate 3 from bottom to top, and a built-in connection structure is used to ensure the beauty of the appearance.

[0021] Among them, the support plate 5 can be made of circular steel plate, and the supporting vertical connecting plate 6 and the support plate 5 can be connected by welding. The support plate 5 and the supporting vertical connecting plate 6 constitute a central connection structure, which can be connected to the surrounding transition layer keels 8. The position and number of the transition layer keels 8 can be adjusted according to the construction position requirements of the truss structure, and the supporting vertical connecting plate 6 can also be adjusted accordingly, so it is relatively flexible.

[0022] The supporting vertical connecting plate 6 and the transfer layer keel vertical connecting plate 9 are first matched with each other in a vertical fitting manner and then connected with fasteners. Specifically, the transfer layer keel vertical connecting plate 9 and the supporting vertical connecting plate 6 are connected by multiple connecting bolts 10 arranged vertically, and the connection is firm and reliable.

[0023] In this embodiment, if Figure 4As shown, there are four conversion layer keels 8 that are evenly arranged around the support plate 5, and the supporting vertical connecting plates 6 are arranged in a cross shape to facilitate the formation of a grid-like conversion structure.

The horizontal ceiling keels 13 are combined into a mesh structure. The lower side of the horizontal ceiling keel 13 is covered with a ceiling finishing layer 16. The structure is simple and can be flexibly connected to the transition layer keel 8. The ceiling finishing layer 16 is connected and fixed to the horizontal ceiling keel 13 via a keel connector 15. The connection point between the vertical ceiling keel 12 and the horizontal ceiling keel 13 is located at the intersection of the horizontal ceiling keels 13, which ensures stable and reliable installation.

[0025] To sum up, the technical solution in this embodiment forms a conversion connection structure by setting supporting vertical connecting plates, conversion layer keel vertical connecting plates and conversion layer keels, so that the grid ball nodes do not need to be welded or cut twice, thereby achieving a firm connection between the ceiling and the grid structure and meeting the requirements of the design and decorative effects.
