Description

Technical Field

[0001] This invention relates to the field of connecting corridor support technology, and in particular to a steel structure connecting corridor support and its construction method. Background Technology

[0002] Steel structure corridors are a common type of building structure. The design specifications and load-bearing requirements of steel structure corridors are key to ensuring their safety and stability. The seismic requirements of steel structure corridors should meet the requirements of relevant standards and specifications. The load-bearing requirements of steel structure corridors mainly include load standards, bearing capacity, stability requirements, seismic requirements, and safety factors. Seismic requirements include bearing capacity, stability, and deformation capacity under seismic action.

[0003] Chinese patent CN103541430B discloses a steel structure corridor support connection structure for connecting the I-beams of the steel structure corridor to the main building structure. The support connection structure includes hinged support nodes and sliding support nodes, which are respectively located at both ends of the steel structure corridor. The sliding support node includes embedded parts, support plates, and limiting plates (blocks). The embedded parts are integrally formed and connected to the main building structure. The I-beams are connected to the embedded parts through the support plates. The limiting plates are located on the support plates and the I-beams.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: when the height of both the building and the connecting corridor is relatively large, strong winds and earthquakes will exert relatively large forces on the high-rise building, causing the connecting corridor to sway and potentially collide with the building walls, thus posing a certain hidden danger to the safety of the building walls. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a steel structure connecting corridor support and its construction method.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a steel structure connecting corridor support, comprising a connecting corridor body disposed between the walls of two buildings and a support structure fixed to the building walls for supporting the connecting corridor body. The support structure includes an mounting seat fixed to the building walls, a set of fixing plates fixed to the bottom of the connecting corridor body and arranged in groups, a connecting column movably connected to both of the set of fixing plates, and a movable ball fixed to the lower end of the connecting column. The mounting seat is provided with a spherical groove movably connected to the movable ball. The top of the mounting seat is provided with a connecting groove for the connecting column to move and communicating with the top of the spherical groove. The top of the mounting seat is provided with a buffer assembly for connecting to the connecting column.

[0007] By adopting the above technical solution, the connecting corridor body will sway under the action of strong winds and earthquakes. The fixed plate at the bottom of the connecting corridor body is rotatably connected to the upper end of the connecting column, the movable ball is movably connected to the spherical groove on the mounting base, and the connecting column is matched with the connecting groove at the top of the mounting base, which provides clearance space for the swaying of the connecting corridor body. The buffer component plays a good buffering role, reduces the probability of collision between the connecting corridor body and the building wall, and enhances the safety of the connecting corridor body during use.

[0008] Furthermore, the mounting base consists of two mounting blocks symmetrically arranged about the movable ball. One of the mounting blocks has a connecting bolt that fits through it with a clearance, and the other mounting block has a threaded hole on its side wall that is threaded to the end of the connecting bolt.

[0009] By adopting the above technical solution, the mounting base is composed of two mounting blocks joined together, and the two mounting blocks are fixed by connecting bolts, which makes it easy for workers to install the movable ball on the two mounting blocks.

[0010] Furthermore, the buffer assembly includes a vertical plate fixed to the top of one of the mounting bases and located on one side of the connecting column, a first spring fixed between the vertical plate and the connecting column, an intermediate block fixed to the top of the mounting base and located on the other side of the connecting column, and a second spring fixed between the intermediate block and the connecting column.

[0011] By adopting the above technical solution, the first spring and the second spring have good buffering performance. When the connecting corridor body sways under the action of strong wind and earthquake, they play a good buffering role, further reducing the probability of the connecting corridor body colliding with the building wall.

[0012] Furthermore, a rotating shaft that is rotatably connected to the fixing plate is fixed on the side wall of the connecting column near the upper end of the connecting column, and a rubber rod is fixed on the side wall of the vertical plate near the middle block. The first spring and the second spring are both sleeved on the rubber rod, and the rubber rod passes through the connecting column and is in clearance fit with the connecting column.

[0013] By adopting the above technical solution, the rubber rod is made of rubber material. During the shaking of the connecting corridor body, the rubber rod plays a good guiding and limiting role for the first and second springs, enhancing the stability of the first and second springs during use. On the other hand, the rubber rod further improves the buffering effect of the buffer assembly.

[0014] Furthermore, sleeves are fixed on both sides of the connecting column, and the ends of the first spring and the second spring that are close to each other are fixed to the inside of the two sleeves respectively. There are two of each of the vertical plate, connecting column, movable ball, first spring and second spring.

[0015] By adopting the above technical solution, the support effect on the main body of the connecting corridor is enhanced, and the buffering effect during the swaying process of the main body of the connecting corridor is also enhanced.

[0016] Furthermore, the connecting groove is funnel-shaped, and a frustum-shaped rubber block is attached and fixed to the inner wall of the connecting groove. Rubber buffer blocks are fixed at both ends of the connecting corridor body, and the side of the rubber buffer block away from the connecting corridor body abuts against the side wall of the building.

[0017] By adopting the above technical solution, the rubber block is shaped like a frustum and matches the funnel-shaped connecting groove, which enhances the stability of the connecting column during the swaying process of the connecting corridor body and plays a good buffering role. The setting of the rubber buffer block plays a good buffering role for the corresponding position of the building wall and the connecting corridor body, and further enhances the protection effect of the building wall.

[0018] Furthermore, each of the mounting blocks has a connecting plate integrally formed on the side that is far apart from each other. A fixing bolt that is clearance-fitted to the connecting plate is provided through the connecting plate, and the fixing bolt is threadedly connected to the building wall.

[0019] By adopting the above technical solution, the setting of fixing bolts facilitates the fixing of the mounting block to the building wall.

[0020] This invention also discloses a construction method for a steel structure connecting corridor support, comprising the following steps:

[0021] S1. Fix one of the mounting blocks to the bottom of the passageway on the side wall of the building using fixing bolts. Set a fixing plate at the bottom of the connecting corridor body. The connecting column is rotatably connected to the fixing plate through a rotating shaft. A rubber block is fitted on the connecting column.

[0022] S2. Install the connecting corridor body so that the movable ball engages with the spherical groove on the mounting block fixedly installed on the building wall, and the rubber block engages with the connecting groove on the mounting block.

[0023] S3. Install another mounting block, install a buffer assembly on top of the other mounting block, and fix the mounting block with fixing bolts. Finally, fix the rubber buffer block at the end of the connecting corridor body, and fix the two mounting blocks with connecting bolts.

[0024] In summary, the present invention has the following beneficial effects:

[0025] 1. In this application, under the action of strong winds and earthquakes, the connecting corridor body will sway. The fixed plate at the bottom of the connecting corridor body is rotatably connected to the upper end of the connecting column, and the movable ball is movably connected to the spherical groove on the mounting base, providing clearance space for the swaying of the connecting corridor body. The buffer component plays a good buffering role, reducing the probability of collision between the connecting corridor body and the building wall, and enhancing the safety of the connecting corridor body during use.

[0026] 2. In this application, the rubber block is frustum-shaped and fits into the funnel-shaped connecting groove, which enhances the stability of the connecting column during the swaying process of the connecting corridor body and plays a good buffering role. The setting of the rubber buffer block plays a good buffering role for the corresponding position of the building wall and the connecting corridor body, and further enhances the protection effect of the building wall.

A fixing bolt 51 with clearance fit is provided through the connecting plate 5, and the fixing bolt 51 is threadedly connected to the building wall 4. The fixing plate 22 is fixed to the bottom of the connecting corridor body 1 and is arranged in a group. A rotating shaft 231 is fixed on the side wall of the connecting column 23 near the upper end of the connecting column 23, and the rotating shaft 231 is rotatably connected to the fixing plate 22. The top of the movable ball 24 is fixed to the lower end of the connecting column 23. A spherical groove 212 is provided in the mounting base 21 to be movably connected to the movable ball 24, and a connecting groove 214 is provided on the top of the mounting base 21 to allow the connecting column 23 to move and communicate with the top of the spherical groove 212.

[0033] The buffer assembly 3 is disposed on the top of the mounting base 21 for connection with the connecting column 23. The buffer assembly 3 includes a vertical plate 31 fixed to the top of one of the mounting bases 21 and located on one side of the connecting column 23, a first spring 32 fixed between the vertical plate 31 and the connecting column 23, a middle block 33 fixed to the top of the mounting base 21 and located on the other side of the connecting column 23, and a second spring 34 fixed between the middle block 33 and the connecting column 23 (specifically: sleeves 6 are fixed on both sides of the connecting column 23, and the ends of the first spring 32 and the second spring 34 that are close to each other are fixed to the inside of the two sleeves 6 respectively. There are two of each of the vertical plate 31, the connecting column 23, the movable ball 24, the first spring 32, and the second spring 34). In this embodiment, a rubber rod 311 is fixed on the side wall of the vertical plate 31 near the middle block 33. The first spring 32 and the second spring 34 are both sleeved on the rubber rod 311. The rubber rod 311 passes through the connecting column 23 and is in clearance fit with the connecting column 23. Under the influence of strong winds and earthquakes, the connecting corridor body 1 will sway.

During the swaying process of the connecting corridor body 1, the rubber rod 311 plays a good guiding and limiting role for the first spring 32 and the second spring 34, enhancing the stability of the first spring 32 and the second spring 34 during use. On the other hand, the rubber rod 311 further improves the buffering effect of the buffer component 3, reduces the probability of collision between the connecting corridor body 1 and the building wall 4, and enhances the safety of the connecting corridor body 1 during use.
