Description

Technical Field

[0001] The utility model relates to a flexible connecting railing structure located at both sides of a building deformation joint. Background Art

[0002] In modern construction projects, expansion joints are gaps reserved to accommodate structural deformation caused by temperature changes, foundation settlement, earthquakes and other factors. The existence of expansion joints is of great significance to ensure the overall stability and safety of the building. However, the design and connection method of the railings at the expansion joints have always been one of the important issues that need to be solved in the project. The traditional expansion joint railing connection method usually adopts a rigid connection, that is, the two sides of the railing are connected to the floor slabs on both sides of the expansion joint by a fixed method. However, this rigid connection method has major defects in actual use.

[0003] When a building settles, moves, or is subjected to external forces, the rigidly connected railings cannot adapt to this structural deformation, causing the railings to be easily damaged by tension or compression, posing a serious safety hazard. For example, during an earthquake or uneven settlement of the foundation, the rigidly connected railings may break or deform, endangering the safety of personnel. In addition, rigidly connected railings are also prone to stress concentration due to thermal expansion and contraction in daily use, which can damage the railings and increase maintenance and replacement costs. Utility Model Content

[0004] The utility model aims to provide a flexible connecting railing structure located on both sides of a building deformation joint, which can ensure the stability and continuity of the railing and adapt to the deformation of the building deformation joint.

[0005] The purpose of the utility model is achieved in this way:

[0006] A flexible connecting railing structure located on both sides of a building deformation joint comprises a floor, a first railing and a second railing, wherein the floor is provided with a deformation joint, the deformation joint divides the floor into a first floor portion and a second floor portion, the first railing is provided in the first floor portion, and the upper part, the middle part and the lower part of the first railing are respectively provided with a first connecting rod in the direction of the deformation joint;

[0007] The first railing is arranged on the second floor portion, and the upper portion, the middle portion and the lower portion of the second railing are respectively provided with second connecting rods in the direction of the deformation joint;

[0008] It also includes a connecting sleeve, a bolt and a rubber cushion layer, wherein the bottom of the connecting sleeve is respectively provided with a transverse sliding groove near the front port position and the rear port position thereof;

[0009] The first connecting rod is inserted into the inner cavity of the connecting sleeve through the front port, the bolt passes through the transverse slide groove to lock the first connecting rod, and the rubber cushion layer is arranged between the first connecting rod and the connecting sleeve;

[0010] The second connecting rod passes through the rear port and is inserted into the inner cavity of the connecting sleeve. The bolt passes through the transverse sliding groove to lock the second connecting rod. The rubber cushion layer is arranged between the second connecting rod and the connecting sleeve.

[0011] Strong ability to cope with deformation: The structure uses the elastic connection design of rubber cushion and connecting sleeve, so that the railing can effectively absorb and disperse the deformation stress caused by external forces such as temperature change, foundation settlement, earthquake, etc. The upper, middle and lower connecting rods of the railing can move and twist freely in the direction of the deformation joint, thereby adapting to the natural deformation and expansion and contraction of the building and maintaining the integrity and stability of the railing.

[0012] Reduce damage to railings: Due to the use of elastic connectors (rubber pads), railings can move slightly at the deformation joints, reducing the risk of railing damage caused by deformation of the deformation joints. Compared with rigid connection methods, flexible connection methods can effectively prevent railings from being over-stretched or compressed due to deformation, reduce the possibility of breakage or deformation, and thus extend the service life of railings.

[0013] Improve safety: The elastic connection design can absorb and disperse the stress generated by the deformation joint, reduce the risk of fracture caused by stress concentration, and improve the safety of the railing. In extreme cases such as earthquakes, the flexible connection allows the railing to move within a certain range, avoiding potential damage caused by the fracture or fall of the rigid connection railing during an earthquake, and improving the overall safety of the building.

[0014] Easy installation and maintenance: The installation of elastic connectors is usually simple and the maintenance cost is relatively low. Due to its good elasticity, even if there is slight deformation or wear during use, the performance can be restored by simply adjusting or replacing the connector. This design not only reduces the difficulty of construction, but also reduces the complexity and cost of subsequent maintenance and replacement.

[0015] Wide applicability: This patented design is applicable to railings of various types and materials, including metal railings, wooden railings, and glass railings. Through reasonable elastic connection design, it can adapt to deformation joints, so that the structure can be widely used in different building scenes, improving the adaptability and construction efficiency of actual projects.

[0016] Improved earthquake resistance: In areas with frequent seismic activity, the flexible connection railing design takes into account earthquake resistance requirements to ensure that the railing can remain stable during an earthquake. The flexible connection can absorb and disperse energy during an earthquake, reducing the risk of damage to the railing and building structure, and improving the earthquake resistance and safety of the building.

[0017] Wide range of applicable expansion joints: The flexible connecting railing structure is suitable for expansion joints with a width of 100 to 400 mm, and has strong adaptability to meet the needs of different construction projects. This wide applicability allows this patent to be applied in a variety of different architectural designs, further enhancing its practical value.

[0018] The purpose of the utility model can also be solved by the following technical measures:

[0019] Furthermore, the length of the transverse slide groove is greater than the length of the deformation joint.

[0020] Enhance the deformation adaptability of the railing: The length of the transverse chute is greater than the length of the deformation joint, so that the connecting rod has a larger range of movement in the chute, and can better adapt to the larger deformation of the building caused by factors such as foundation settlement, temperature changes and earthquakes. This design ensures that the railing can remain stable and intact under large deformation conditions, further improving the flexible connection performance of the railing structure.

[0021] Improve the reliability and safety of the connection: The longer transverse groove allows the connecting rod to slide freely in the deformation joint, reducing stress concentration, thereby reducing the risk of the connecting rod breaking or falling off due to excessive stress. This design significantly improves the safety of the railing, especially in extreme cases such as earthquakes, and can effectively protect the overall safety of the railing and building structure.

[0022] Extend the service life of the railing: By increasing the length of the horizontal slide, the connection parts of the railing can better disperse the stress and deformation pressure, reduce the wear of the connectors and rubber pads, thereby extending the service life of the railing and connectors, reducing the maintenance and replacement frequency, and saving the maintenance cost of the building.

[0023] Improve the convenience of installation and maintenance: Due to the increase in the length of the chute, there is more room for adjustment during installation, and construction workers can more easily align and fix the connecting rod, simplifying the installation process. At the same time, during maintenance or replacement, the connecting rod has more adjustment space in the chute, which is convenient for disassembly and reinstallation, further improving the convenience of maintenance.

[0024] Enhanced seismic performance: When an earthquake occurs, the building will produce large horizontal displacement and deformation. The design of the chute length being longer than the deformation joint length allows the railing to have more room to move during an earthquake, effectively alleviating the impact of the earthquake on the railing structure, enhancing the seismic performance of the railing, and ensuring that the railing remains functional and safe during and after an earthquake.

[0025] Furthermore, the length of the transverse slide groove is between 100 mm and 400 mm.

[0026] Wide applicability: The length of the horizontal slide is designed to be between 100mm and 400mm, so that the flexible connection railing structure can adapt to the size range of most building deformation joints. This wide range of application enables the railing structure to be applied to various building types and scenes, improving its versatility and practicality.

[0027] Enhanced seismic performance: The slide design ranging from 100mm to 400mm in length allows the railing to have sufficient room to move during an earthquake, which can effectively absorb and disperse the energy generated by the earthquake, enhance the seismic performance of the railing, and ensure that the railing remains functional and safe during and after an earthquake.

[0028] The beneficial effects of the utility model are as follows:

[0029] The utility model overcomes the disadvantage that traditional rigid connection railings are easily damaged at deformation joints by introducing elastic materials and reasonable connection design, significantly improves the stability, safety and adaptability of the railings, and has broad application prospects.

[0030] The utility model is designed that the length of the transverse slide groove is greater than the length of the deformation joint. This enhances the deformation adaptability of the railing, improves the reliability and safety of the connection, extends the service life of the railing, and improves the convenience of installation and maintenance, thereby effectively enhancing the overall performance and application value of the railing structure.
