[0018] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods and in conjunction with the accompanying drawings.

[0019] A novel smoke barrier vertical wall connection structure includes a fixed part 1, a connection part 2 and a fireproof part 3, wherein the connection part 2 includes a square tube 2-2, which is a hot-dip galvanized square tube. The square tube 2-2 is a factory-prefabricated and cut square tube, and through holes are reserved on the square tube 2-2 for installing bolt assemblies 1-2 and bolt assemblies 3-1. The outer side of the square tube 2-2 is covered with a fireproof board 2-1. The fireproof board 2-1 is a Class A fireproof board, which is a factory-prefabricated and cut fireproof board. The interior of the square tube 2-2 is filled with fireproof rock wool 2-3. The upper end of the square tube 2-2 is detachably fixedly connected to the lower end of the fixed part 1, the upper end of the fixed part 1 is fixedly connected to the building ceiling, and the lower end of the square tube 2-2 is detachably fixedly connected to the upper end of the fireproof part 3. The fireproof board 2-1 and the fireproof rock wool 2-3 form a double blocking structure. Square tube 2-2 is manufactured through factory processing, which further reduces the workload on site.

[0020] The fixed part 1 includes an L-shaped embedded plate 1-3, which is an L-shaped hot-dip galvanized steel plate. The L-shaped embedded plate 1-3 is a factory-prefabricated L-shaped plate, and a through hole for installing the bolt assembly 1-2 is reserved on the L-shaped embedded plate 1-3, which is convenient for the construction site to quickly install the bolt assembly 1-2, which is conducive to improving the on-site construction efficiency. One end of the L-shaped embedded plate 1-3 is fixedly connected to the building ceiling by an expansion bolt 1-1, which ensures the stability of the connection between the L-shaped embedded plate 1-3 and the main structure. The other end of the L-shaped embedded plate 1-3 is detachably fixedly connected to the upper end of the square tube 2-2 by the bolt assembly 1-2.

[0021] The fireproof part 3 includes a fireproof glass 3-2, which is prefabricated and cut in a factory, and a through hole for installing a bolt assembly 3-1 is reserved on the fireproof glass 3-2, which can reduce the workload on site and facilitate the replacement and maintenance of the fireproof glass 3-2 after damage. The upper end of the fireproof glass 3-2 is detachably fixedly connected to the lower end of the square tube 2-2 through the bolt assembly 3-1.

[0022] In the utility model, the L-shaped buried plate 1-3 and the square tube 2-2 are made of hot-dip galvanized material and connected by bolts. Compared with the common welding connection method and on-site spray anti-rust method in the prior art, the stability of the fixed part can be ensured, and the service life and turnover rate can be improved. At the same time, the L-shaped buried plate 1-3 can be processed in a factory, avoiding the work of cutting, welding, punching, etc. on site, thereby saving assembly time. The components are connected by bolts to form a fixed integral structure as the first connection.

[0023] Square tube 2-2, fireproof board 2-1 and fireproof rock wool 2-3 are all finished structures. Square tube 2-2 and fireproof board 2-1 are uniformly sized according to the site and cut and manufactured in the factory, thereby improving the accuracy and reducing the materials, and further reducing the workload of on-site construction, speeding up the construction rhythm, reducing costs and increasing efficiency, as the second connection.

[0024] The fireproof glass 3-2 is connected to the square tube 2-2 by a bolt assembly 3-1, which is convenient for subsequent work such as maintenance and replacement, and serves as the third connection.

[0025] Through the above connection structure, the fixed part 1, the connecting part 2 and the fireproof part 3 can be connected as a whole, with good overall rigidity, high strength, strong deformation resistance, lightness and convenience for movement. The overall appearance is beautiful and atmospheric, and it is easy to install and disassemble, which well solves the disadvantages of traditional welding connection methods.

[0026] The technical features not described in the present invention can be realized by existing technologies and will not be described here. The present invention is not limited to the above specific implementation methods, and changes, modifications, additions or substitutions made by ordinary technicians in the field within the essential scope of the present invention should also fall within the protection scope of the present invention.
