Description

Technical Field

[0001] This utility model belongs to the field of building structure technology, specifically relating to a prefabricated rear-mounted external connecting corridor. Background Technology

[0002] A connecting corridor is a structure that connects buildings. Installing an aerial connecting corridor between two adjacent or related buildings can effectively enhance the internal connection between the two buildings. The two ends of the corridor are connected to the main body of the two buildings, enabling the transportation of materials and the movement of people between the two buildings. To achieve wind and rain protection, existing connecting corridors are enclosed. However, existing enclosed connecting corridors have the following problems during installation:

[0003] First, sealed connecting corridors need to be poured on-site, and during construction, a large area of ​​the existing building walls needs to be excavated, resulting in a long construction time.

[0004] Second, in order to shorten the construction period, the use of prefabricated connecting corridors has obvious advantages. However, prefabricated connecting corridors are mostly integral structures, which require the use of large equipment during installation. Large equipment has certain limitations on the installation environment, resulting in high operational requirements and difficulty in the assembly process, and a lack of standardized assembly process. Utility Model Content

[0005] To address the problems mentioned in the background section, the purpose of this utility model is to provide a prefabricated, rear-mounted external connecting corridor.

[0012] Preferably, upper right-angle reinforcing ribs are connected to the right angles of both sides of the right-angle bracket, and lower right-angle reinforcing ribs are connected to both sides of the right angle between the right-angle bracket and the lower fixing plate.

[0042] The connection methods of the through-wall lower support 1 and through-wall upper support 2 of the rear-mounted external connecting corridor to the two original main buildings are specifically selected according to design requirements. One connection method ensures that the through-wall lower support 1 and through-wall upper support 2 of the rear-mounted external connecting corridor are connected to the beams and columns of the two original main buildings, specifically by having the through-wall lower support 1 and / or through-wall upper support 2 directly connect through the beams and columns of the original main buildings. Another connection method is to connect the through-wall lower support 1 and through-wall upper support 2 of the rear-mounted external connecting corridor to the shear walls of the two original main buildings.

[0043] This invention facilitates the advancement of green building assembly and provides impetus for rapid building assembly.

[0044] One working principle of this utility model is as follows: During installation, the lower support is mounted using the through-wall type lower support body 1. During installation, the right-angle bracket 1-11 is installed on the building wall. Then, the crossbeam 1-3 is installed on the crossbeam fixing seat 1-2, so that the crossbeam square rod 1-31 is inserted into the fixing groove 1-21 of the crossbeam fixing seat 1-2. The connecting screw 1-32 is inserted into the elongated fixing hole 1-22 and fixed with a nut. At this time, the through-wall type upper support body 2 is installed on the building wall. During the installation of the through-wall type upper support body 2, the installation is achieved by fixing the side plate 2-2 with expansion bolts. Simultaneously, the lower fixing plate 2-4 is connected to the right-angle bracket... The outer end of the frame 1-11 is connected, and the right-angle hanger 2-1 is strengthened by the outer reinforcing body 2-3, the upper right-angle reinforcing rib 2, and the lower right-angle reinforcing rib 2-6, making it less prone to deformation and cracking, and with high stability. At this time, the bottom support plate 5 is installed on the upper end of the wall-penetrating lower support body 1. The bottom support plate 5 is a prefabricated plate, and multiple pieces are assembled and installed by butt joint. The rainproof canopy 3 and the side rainproof plate 4 are installed on the wall-penetrating upper support body 2, which can block wind and rain. When installing the rainproof canopy 3, sealant needs to be injected into the inner sealing groove 3-21 and the outer sealing groove 3-22 or a sealing gasket needs to be installed to improve the sealing performance.
