Description

[Technical Field]

[0002] This utility model relates to the field of building steel structures, and in particular to a connecting structure for a steel corridor in a high-rise building. [Background Technology]

[0004] Connecting corridors, originally a form of ancient Chinese architecture, are structures that connect buildings. In high-rise buildings, connecting corridors serve as bridges between two buildings, providing convenient walking passages for people. Steel connecting corridors have advantages such as light weight, high strength, and convenient construction, and are often used in high-rise building connecting corridors. Currently, in high-rise steel structures, connecting corridors are often placed on columns and corbels. Steel columns need to be set at the location of the connecting corridor, and the column cross-section must be large enough to meet the installation requirements of the connecting corridor. When placed on columns and corbels, since the columns and corbels are fixed, the installation position of the connecting corridor is also fixed, making it difficult to change the installation position of the connecting corridor. [Utility Model Content]

[0006] To overcome the problem that the installation position of the connecting corridor is fixed because the columns and corbels are fixed, making it difficult to change the installation position, the technical problem to be solved by this utility model is to provide a steel structure connecting corridor connection structure for high-rise buildings. This utility model is achieved by the following technical solution:

[0007] A steel structure corridor connecting structure for high-rise buildings includes a main building steel structure for connecting with the floor buildings and bearing the main supporting force. The main building steel structure has a steel corridor at the end away from the floor buildings, which allows the two buildings to pass through each other. The steel corridor and the main building steel structure are provided with a base that is independently connected to the main building steel structure and can reduce the vibration transmission between the two buildings when connected to the steel corridor.

[0008] As described above, a high-rise building steel structure connecting corridor is provided, wherein the base includes a connecting corridor base connected to the main building steel structure and a sliding support connected to the steel connecting corridor.

[0009] As described above, a high-rise building steel structure connecting corridor is provided, wherein the corridor base includes flanges determined according to the bottom area of ​​the sliding support, a web is provided between the two flanges, and a base steel side beam is connected to the outside of the web.

[0010] As described above, in a high-rise building steel structure connecting corridor, a connecting plate and bolts are provided between the base steel side beam and the web plate to connect the base steel side beam and the corridor base.

[0011] As described above, a high-rise building steel structure corridor connection structure, wherein the main building steel structure includes main building secondary steel beams connected to the building structure and main building main steel beams connected to the base.

[0012] As described above, a high-rise building steel structure connecting corridor is provided, wherein the main building steel main beam includes a main beam flange and a main beam web, the main beam web is provided with a reserved steel sleeve, and the steel connecting corridor is provided with a reserved perforated steel plate.

[0013] As described above, a high-rise building steel structure corridor connection structure is provided with a headed steel bar between the reserved steel sleeve and the reserved perforated steel plate, which passes through the reserved perforated steel plate and the reserved sleeve to connect the reserved steel sleeve and the reserved perforated steel plate.

[0014] As described above, in a high-rise building steel structure connecting corridor, the sliding support is an earthquake-resistant spherical support.

[0015] As described above, in a high-rise building steel structure connecting corridor, the sliding support is a lead-core rubber support.

[0016] The steel structure connecting corridor of a high-rise building, as described above, is a fish-belly shaped steel beam.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. The steel structure connecting corridor of this high-rise building does not require the setting of steel column brackets as the base of the steel connecting corridor. It can be set at any position on the outside of the structure, which makes it more flexible and convenient to set the position of the steel structure connecting corridor of the high-rise building, while meeting the requirements of architectural effect.

[0019] 2. In the existing connecting corridor structure, the height of the high-rise steel structure connecting corridor slab set at the mid-span of the main beam is higher than the height of the indoor floor slab, requiring the addition of stairs inside to access the connecting corridor, which is inconvenient to use. This structure, by lowering the base elevation, can achieve a main building floor slab higher than the connecting corridor floor slab, meeting waterproofing requirements and being convenient to use.

[0020] 3. The steel beams on both sides serve as a limiting measure for lateral sliding, providing higher safety. The perforated steel plates on the flanges of the steel beams are connected to the web of the main beam through steel bars or prestressed tendons, which has a good anti-fall effect and is economical, practical, and convenient and quick to construct on site.

Detailed Implementation Methods

[0028] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0029] Please see Figures 1 to 4 A high-rise building steel structure connecting corridor includes a main building steel structure 1 for connecting to the floor buildings and bearing the main supporting force. The main building steel structure 1 has a steel connecting corridor 2 at the end furthest from the floor buildings, allowing passage between the two buildings. A base 3 is independently connected to the main building steel structure 1 and, when connected to the steel connecting corridor 2, reduces vibration transmission between the two buildings. The robust connection between the main building steel structure and the floor buildings ensures the overall stability and anti-overturning capacity of the structure. In conventional high-rise building connecting corridors, the corridor is often placed on column corbels, requiring steel columns with sufficiently large cross-sections to meet the placement requirements. This design cannot change the connection position of the corridor between the two buildings and the dismantling process is time-consuming, increasing labor costs. This design eliminates the steel column corbels as the base of the steel connecting corridor, allowing it to be placed at any location outside the building structure, improving the flexibility of the steel connecting corridor and meeting architectural requirements.

[0030] Furthermore, as a preferred embodiment of this solution and not a limitation, the base 3 includes a connecting corridor base 31 connected to the main building steel structure 1 and a sliding support 32 connected to the steel connecting corridor 2. The connecting corridor base 31 includes flanges 311 determined according to the bottom area of ​​the sliding support 32, and a web 312 is provided between the two flanges 311. A base steel side beam 313 is connected to the outside of the web 312. A connecting plate 314 and bolts 315 are provided between the base steel side beam 313 and the web 312 for connecting the base steel side beam 313 and the connecting corridor base 31. 1. It consists of upper and lower flanges, three web plates, two cantilever steel beams, and sliding supports. The flanges include upper and lower flanges. The upper flange is connected to the sliding support. First, the required sliding amount of the steel corridor is determined by calculation. The size of the bottom surface of the sliding support is determined by the sliding amount, thereby determining the width of the upper and lower flange plates. Then, three steel web plates are set at the center of the sliding support and at the farthest sliding position on both sides. A transverse stiffening rib is set at the center of the support and at the mid-span position. The upper and lower flanges, web plates, and stiffening ribs are welded into a whole. The base steel side beams are connected to the three steel web plates by double connecting plates and high-strength bolts.

[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, the sliding support 32 includes an anti-seismic spherical support or a lead-core rubber support, which is welded to the upper flange plate of the connecting corridor base through a combination of partial penetration and fillet welds. The steel connecting corridor and the sliding support are fixed by fillet welds. The anti-seismic spherical support can maintain vertical support force, effectively disperse seismic energy, and reduce structural damage during earthquakes. The lead-core rubber support absorbs seismic energy through the plastic deformation of the lead core, reduces the vibration amplitude of the structure, and improves the seismic performance of the building. The sliding support can effectively reduce the vibration of the structure under dynamic loads such as wind loads and traffic loads, and improve the comfort and safety of the structure. The combination of partial penetration and fillet welds ensures a firm connection between the sliding support and the base, improving the overall stability and overturning resistance of the structure.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, the main building steel structure 1 includes a main building secondary steel beam 11 connected to the building structure and a main building main steel beam 12 connected to the base 3. The main building main steel beam bears the vertical loads from the base and the steel corridor and safely transfers these loads to the main building secondary steel beams, and is one of the key load-bearing components in the building structure.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the main steel beam 12 of the main building includes a main beam flange 121 and a main beam web 122. A reserved steel sleeve 1221 is provided on the main beam web 122, and a reserved perforated steel plate 21 is provided on the steel connecting corridor 2. A headed steel bar 120 or prestressed tendon is provided between the reserved steel sleeve 1221 and the reserved perforated steel plate 21, passing through the reserved perforated steel plate 21 and the reserved sleeve 1221 to connect the reserved steel sleeve 1221 and the reserved perforated steel plate 21, thereby forming a fall prevention measure.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the steel connecting corridor 2 is a fish-belly type steel beam. A fish-belly type steel beam is a special type of steel structure whose cross-sectional shape resembles the belly of a fish. The design of the fish-belly type steel beam can effectively distribute and transfer loads, reduce stress concentration within the structure, and improve the overall load-bearing capacity. Especially in large-span structures, it can effectively resist bending and torsion.

[0035] The working principle of this embodiment is as follows:

[0036] A process for using a steel structure connecting corridor in a high-rise building: The steel structure connecting corridor consists of a main building steel structure, a base, and a steel connecting corridor. The main building steel structure is connected to the base by bolts and welds. Sliding supports are installed on the base, and the steel connecting corridor rests on the sliding supports. It can be set at any position on the outer edge of the structure, which is flexible and can meet the requirements of the building facade. The steel beam flanges are pre-reserved with perforated steel plates and connected to the web of the main beam by steel bars or prestressed tendons, which has a good anti-fall effect, and is economical, practical, and convenient and quick to construct on site.

[0037] The above are implementation methods provided in conjunction with specific content, and it is not intended that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
