Description

Technical Field

[0001] This utility model relates to the field of civil building engineering technology, and more specifically, to a sliding connection structure and building structure of a seismic-resistant and fall-prevention steel corridor. Background Technology

[0002] In recent years, with the diversification of architectural forms, many buildings are connected by sky bridges for pedestrian access. Seismic joints are typically installed between the steel sky bridge and the main building to release deformation and displacement between the two buildings during an earthquake. This places higher demands on the design of seismic bearings, especially since steel sky bridges pose a risk of collapse during an earthquake, which would severely threaten people below. However, traditional steel sky bridge bearings are not only expensive but also lack sufficient fall protection.

[0003] Existing steel connecting corridor supports typically use spherical supports or plate rubber supports, but they are expensive, have complex structures, require high levels of construction technology, and lack fall protection. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a sliding connection structure for a seismic-resistant and fall-prevention steel connecting corridor;

[0005] The solution adopted by this utility model to solve the technical problem is:

[0006] on the one hand:

[0007] This utility model discloses a sliding connection structure for an earthquake-resistant and fall-prevention steel corridor, including a corbel support set on the outside of the main building structure, a limiting column installed on the side of the corbel support away from the main building structure and extending into the steel corridor, and an earthquake-resistant sliding support installed on the corbel support.

[0008] In some possible implementations, the ends of the steel connecting corridor are mounted on seismic sliding bearings, and a seismic deformation joint is formed between the end face of the steel connecting corridor and the outer side of the main building structure.

[0009] In some possible implementations, the seismic sliding bearing includes a pre-embedded steel plate mounted on a corbel bearing and a polytetrafluoroethylene plate mounted on the pre-embedded steel plate.

[0010] In some possible implementations, the seismic expansion joint is filled with a buffer material.

[0011] In some possible implementations, edge-sealing beams are also provided at both ends of the steel connecting corridor.

[0012] In some possible implementations, the corbel support is located on the outside of the main beam in the main structure of the building and is integrally formed with the main beam.

[0013] In some possible implementations, the limiting posts are in multiple sets and are arranged along the length of the main beam.

[0014] on the other hand:

[0015] This utility model discloses a building structure, including multiple sets of main building structures, a sliding connection structure for earthquake-resistant and fall-prevention steel corridors with adjacent sets of main building structures close to each other and as described above, and a steel corridor installed on the sliding connection structure for earthquake-resistant and fall-prevention steel corridors; the bottom of the sliding connection structure for earthquake-resistant and fall-prevention steel corridors and the bottom of the steel corridors are on the same plane.

[0016] In some possible implementations, the steel connecting corridor includes multiple sets of parallel main beams with their ends mounted on seismic sliding supports, and secondary beams for two adjacent sets of main beams; the edge sealing beams are arranged parallel to the secondary beams.

[0017] In some possible implementations, the two ends of the edge sealing beam are respectively connected to the ends of two adjacent sets of main beams on the same side to form an installation cavity, and the top of the limiting column extends into the installation cavity.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model uses polytetrafluoroethylene (PTFE) plates in combination with embedded steel plates as seismic sliding supports. It has low cost and PTFE plates have many excellent properties such as high and low temperature resistance, corrosion resistance, weather resistance, high durability, high lubricity, non-toxicity and harmlessness.

[0020] Compared with the existing technology, this utility model has a simpler structure, is more convenient to construct, and is easier to ensure construction quality. The corbel support is made of cast-in-place reinforced concrete, which is a mature technology that does not require high professional skills from construction personnel, making it easier to ensure construction quality. The seismic sliding bearing medium is made of polytetrafluoroethylene plate + embedded steel plate, which does not require special operation. It is only necessary to place the polytetrafluoroethylene plate under the main beam of the steel connecting corridor. Therefore, the construction operation is simple and the construction quality is easier to ensure.

[0021] This utility model improves the fall prevention of steel connecting corridors by using limiting columns and solves the deformation and displacement between two buildings during an earthquake by using seismic sliding supports.

[0022] This utility model improves the overall rigidity and stability of the steel connecting corridor by setting an edge sealing beam, and at the same time, it can work with the limit column to realize the anti-fall function of the steel connecting corridor.

[0023] This invention utilizes buffer material filled at seismic deformation joints to effectively reduce the impact on the main structure when the steel connecting corridor slides.

[0024] This utility model has a simple structure and is highly practical. Attached Figure Description

[0037] The present invention will now be described in detail.

[0038] like Figures 1-3 As shown:

[0039] on the one hand:

[0040] This utility model discloses a sliding connection structure for a seismic-resistant and fall-prevention steel corridor, including a corbel support 1 set on the outside of the main building structure 10, a limiting column 2 installed on the side of the corbel support 1 away from the main building structure 10 and extending into the steel corridor 20, and a seismic-resistant sliding support 3 installed on the corbel support 1.

[0041] This utility model achieves sliding contact between the steel connecting corridor 20 and the main building structure 10 by installing anti-seismic sliding bearings 3 on the corbel bearings 1 at the ends of the steel connecting corridor 20. By setting limit columns 2, it effectively prevents the steel connecting corridor 20 from falling when the deformation displacement between the two main building structures 10 is too large during an earthquake. The limit columns 2 also effectively prevent the steel connecting corridor 20 from directly detaching from the anti-seismic sliding bearings 3 and falling. This utility model can achieve the function of personnel passage in the prior art, and at the same time, it can prevent falling during an earthquake, which greatly improves the safety of use.

[0042] In some possible implementations, the end of the steel connecting corridor 20 is mounted on the seismic sliding bearing 3 and a seismic deformation joint is formed between the end face of the steel connecting corridor 20 and the outer side of the main building structure 10.

[0043] The seismic deformation joint is filled with buffer material 5;

[0044] Specifically, the buffer material 5 is viscoelastic rubber, high-density polyurethane foam, silicone material, foam rubber, polystyrene foam, etc.

[0045] A seismic deformation joint is formed between the end face of the steel connecting corridor 20 and the outer side of the main building structure 10. By filling the seismic deformation joint with buffer material 5, the buffer material 5 can effectively reduce the impact of the steel connecting corridor 20 on the main building structure 10 when it slides.

[0046] In some possible implementations, the seismic sliding bearing 3 includes a pre-embedded steel plate 31 installed on the corbel bearing 1 and a polytetrafluoroethylene plate 32 installed on the pre-embedded steel plate 31; the corbel bearing 1 is located on the outside of the main beam 101 in the main building structure 10 and is integrally formed with the main beam 101.

[0047] Specifically, both the corbel support 1 and the main beam 101 are reinforced concrete structures. When the main building structure 10 is being constructed, the corbel support 1 will be constructed simultaneously. At the same time, the anchoring steel bars of the pre-embedded steel plate 31 will be pre-embedded in the corbel support 1 during its construction.

[0048] The anti-seismic sliding bearing 3 is formed by combining polytetrafluoroethylene plate 32 with pre-embedded steel plate 31. No special operation is required. The polytetrafluoroethylene plate 32 only needs to be placed under the main beam 201 of the steel connecting corridor 20. Therefore, the construction operation is simple and the construction quality is easier to guarantee.

[0049] The steel connecting corridor 20 is an existing structure. The steel connecting corridor 20 includes multiple sets of parallel main beams 201 with their ends installed on seismic sliding supports 3, secondary beams 202 for two adjacent sets of main beams 201, and a surface layer laid on the support frame formed by the main beams 201 and secondary beams 202; the edge sealing beams 4 are arranged parallel to the secondary beams 202; it also includes edge sealing beams 4 set at both ends of the steel connecting corridor 20; the two ends of the edge sealing beams 4 are respectively connected to the ends of the two adjacent sets of main beams 201 on the same side and form an installation cavity, and the top of the limiting column 2 extends into the installation cavity; multiple sets of polytetrafluoroethylene plates 32 are arranged in a one-to-one correspondence with the main beams 201 of the steel connecting corridor 20, and are set at the bottom of the main beams 201.

[0050] The two ends of the two adjacent sets of main beams 201 are connected by the edge sealing beam 4, so that the support frame forms a stable structure. It will enhance the overall rigidity and stability of the steel corridor 20, and can also serve as a limiting beam to prevent the steel corridor 20 from falling. During the fall of the steel corridor 20, the edge sealing beam 4 will tilt and move, and come into contact with the limiting post 2. Thus, through the cooperation of the limiting post 2 and the edge sealing beam 4, the fall of the steel corridor 20 is effectively limited.

[0051] In some possible implementations, in order for the limiting posts 2 to effectively restrict the steel connecting corridor 20 from falling, the limiting posts 2 are in multiple sets and are equally spaced along the length of the main beam 101.

[0052] During construction, the dimensions of the corbel support 1, the dimensions and quantity of the limiting column 2, the dimensions of the polytetrafluoroethylene plate 32, and the dimensions of the edge sealing beam 4 are determined according to the design requirements.

[0053] When constructing the main beam 101 of the main structure 10 of the building, the corbel support 1 and the limiting column 2 are constructed simultaneously. The limiting column 2 is arranged at certain intervals. The pre-embedded steel plate 31 is pre-embedded on the corbel support 1 and at the position corresponding to the polytetrafluoroethylene plate 32.

[0054] After the corbel support 1 and the limiting column 2 reach the design strength, polytetrafluoroethylene plate 32 is laid at the bottom of the main beam 201 of the steel connecting corridor 20.

[0055] Construct a steel connecting corridor 20, with seismic deformation joints between the ends of the steel connecting corridor 20 and the main structure, and edge sealing beams 4 installed at the ends of the steel connecting corridor 20.

[0056] The construction is completed by filling the seismic deformation joint formed between the end face of the steel connecting corridor 20 and the main building structure 10 with buffer material 5.

[0058] This utility model discloses a building structure, including multiple sets of main building structures 10, a sliding connection structure for earthquake-resistant and fall-prevention steel corridors with adjacent sets of main building structures 10 close to each other and as described above, and a steel corridor 20 installed on the sliding connection structure for earthquake-resistant and fall-prevention steel corridors; the bottom of the sliding connection structure for earthquake-resistant and fall-prevention steel corridors and the bottom of the steel corridor 20 are on the same plane; that is, the bottom of the main beam 201 and the bottom of the corbel support 1 are on the same plane, which improves the overall aesthetic effect of the steel corridor 20.

[0059] In some possible implementations, the steel connecting corridor 20 includes multiple sets of parallel main beams 201 with their ends mounted on seismic sliding supports 3, and secondary beams 202 for two adjacent sets of main beams 201; the edge sealing beam 4 is arranged parallel to the secondary beams 202.

[0060] Two sets of adjacent building main structures 10 are provided with corbel supports 1 integrally formed with the main beams 101 at a certain height on one side of each other; seismic sliding supports 3 are provided on the corbel supports 1, and the two ends of the steel connecting corridor 20 are respectively installed on the seismic sliding supports 3, so that the end faces of the steel connecting corridor 20 form a seismic deformation joint on the side of the building main structure 10 that is close to each other, and the seismic deformation joint is filled with buffer material 5; some of the corbel supports 1 are provided with limiting columns 2 away from the main beams 101 they are connected to, and the top of the limiting columns 2 extends into the installation cavity formed by the two sets of main beams 201, edge sealing beams 4, and secondary beams 202.
