Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective engineering technology, specifically to a flexible protective shed with elastic energy dissipation based on steel structure. Background Technology
[0002] The existing protective tunnel technology has three problems:
[0003] First, the protective structure is simple, mostly a single-layer rigid or flexible protective layer. When faced with falling rocks of different sizes, small stones can easily penetrate or large stones can break through the protective layer, resulting in insufficient protection reliability.
[0004] Secondly, the flexible protective layer of the protective structure is often laid directly on the main steel structure. When rocks fall, they can easily hit the main steel structure directly, resulting in the entire protective shed being damaged before the flexible protective layer has played its buffering role.
[0005] Third, the lack of an effective multi-level energy-dissipating buffer design means that the impact load of falling rocks is directly transmitted to the main steel frame, resulting in concentrated stress on the structure, which is prone to deformation and damage. Furthermore, falling rocks tend to accumulate on the roof, increasing the risk of long-term load-bearing. Utility Model Content
[0006] In response to the aforementioned technical problems, this application solves the issues of the existing protective sheds having a simple structure and lacking effective buffer space.
[0007] To achieve the above objectives, the technical solution adopted in this application is: a steel structure elastic energy-dissipating flexible protective shed, including an arched steel frame, the outside of which is covered with an elastic energy-dissipating flexible protective layer through the cooperation of a connecting support structure and a spring-type energy-dissipating device.
[0008] To better realize this utility model, the arched steel frame further includes multiple support frames in the shape of "∩", and both sides of all the support frames are respectively connected by at least two rows of parallel horizontal supports, so that all the support frames are arranged in a straight line with equal spacing.
[0009] To better realize this utility model, one or more sets of cross supports arranged in a cross pattern are further provided between any two adjacent horizontal supports, and each set of cross supports is located between two adjacent support frames.
[0010] To better realize this utility model, the connecting support structure further includes longitudinal steel wire ropes, transverse steel wire ropes, energy-dissipating and shock-absorbing nodes, and connecting lugs.
[0011] The longitudinal steel wire rope consists of multiple strands, which are suspended at equal intervals along the arched direction of the support frame outside the arched steel frame. The length direction of each longitudinal steel wire rope is consistent with the direction of the straight-line arrangement of all the support frames.
[0012] The transverse steel wire rope consists of multiple strands, which are suspended at equal intervals on the outside of the arched steel frame along the straight-line arrangement of the support frame. The length direction of each transverse steel wire rope is consistent with the arched direction of the support frame. The intersections of the longitudinal steel wire rope and the transverse steel wire rope are all connected and fixed by an energy-dissipating and vibration-damping node to form a cross-arranged grid support structure.
[0013] Each of the energy-dissipating and vibration-damping nodes is connected to the arched steel frame via four spring-type energy-dissipating devices, and the outer surface of the grid support structure is covered with an elastic energy-dissipating flexible protective layer.
[0014] To better realize this utility model, the energy-dissipating and vibration-damping node further includes an outer plate layer, a rubber pad layer and an inner plate layer. The inner side of the outer plate layer is provided with a first channel matching the longitudinal steel wire rope. The longitudinal steel wire rope is sleeved inside the first channel. The outer side of the outer plate layer is provided with a second channel matching the transverse steel wire rope. The transverse steel wire rope is sleeved inside the second channel. The first channel and the second channel are perpendicular to each other.
[0015] The outer plate layer and the inner plate layer are fixedly clamped together by bolts to hold the rubber pad layer. The outer side of the inner plate layer is provided with four first connecting holes, and any one of the first connecting holes is perpendicular to the two lines connecting the other two adjacent first connecting holes.
[0016] The outer side of the support frame is provided with multiple sets of connecting components that are equally spaced along the arch direction. Each set of connecting components consists of two connecting lugs, and each connecting lug is provided with a second connecting hole.
[0017] The four first connection holes on any one of the energy-dissipating and vibration-damping nodes are respectively connected to a corresponding second connection hole on the four connecting lugs through four adjacent spring-type energy-dissipating devices.
[0018] To better realize this utility model, the elastic energy-dissipating flexible protective layer further includes a flexible protective mesh group, which includes a ring mesh and a grid mesh. The ring mesh is disposed outside the mesh support structure, and the grid mesh is disposed outside the ring mesh.
[0019] To better realize this utility model, the aperture of the annular mesh is further larger than the aperture of the grid mesh.
[0020] The technical solution provided by this utility model has the following advantages compared with the prior art:
[0021] This utility model achieves multiple technical advantages through an integrated design of "framework-support-energy dissipation-protection":
[0022] An arched steel frame with cross supports is used to construct a stable main structure, which is combined with steel wire rope mesh support, energy-dissipating and shock-absorbing nodes with rubber pads, spring-type energy-dissipating devices, and double-layer flexible protective netting to form a multi-layered energy-dissipating and synergistic protection system. This system achieves layered interception of falling rocks of different sizes, and through the buffering effect of the rubber pads and the elastic deformation of the springs, it completes the gradual dissipation and stress relief of impact energy. It effectively avoids the problems of single protective layer, insufficient buffer deformation space, and easy failure, optimizes the stress distribution of the structure, reduces the load-bearing risk caused by rock accumulation, significantly improves the impact resistance, stability and service life of the shelter, and reduces maintenance costs.

[0038] Example 1
[0039] like Figures 1 to 7 As shown, the steel structure elastic energy-dissipating flexible protective shed includes an arched steel frame 1. The exterior of the arched steel frame 1 is covered with an elastic energy-dissipating flexible protective layer through the cooperation of a connecting support structure and a spring-type energy-dissipating device 7.
[0040] like Figures 1 to 7 As shown, in this embodiment, the arched steel frame 1 includes multiple support frames in the shape of "∩". Both sides of all the support frames are connected by at least two rows of parallel horizontal supports 3, so that all the support frames are arranged in a straight line with equal spacing.
[0041] like Figures 1 to 7 As shown, in this embodiment, one or more sets of cross supports 2 arranged in a cross pattern are provided between any two adjacent horizontal supports 3 to strengthen the connection, and each set of cross supports 2 is located between two adjacent support frames.
[0042] like Figures 1 to 7 As shown, in this embodiment, the connecting support structure includes a longitudinal steel wire rope 4, a transverse steel wire rope 5, an energy-dissipating and vibration-damping node 6, and a connecting lug plate 9.
[0043] The longitudinal steel wire rope 4 consists of multiple strands, which are suspended at equal intervals along the arched direction of the support frame outside the arched steel frame 1. The length direction of each longitudinal steel wire rope 4 is consistent with the direction of all the support frames arranged in a straight line.
[0044] The transverse steel wire ropes 5 are multiple, and the multiple transverse steel wire ropes 5 are suspended at equal intervals on the outside of the arched steel frame 1 along the straight-line arrangement direction of the support frame. The length direction of each transverse steel wire rope 5 is consistent with the arched direction of the support frame. The intersection of the longitudinal steel wire ropes 4 and the transverse steel wire ropes 5 is connected and fixed by an energy-dissipating and vibration-damping node 6 to form a cross-arranged grid support structure.
[0045] Each of the energy-dissipating and vibration-damping nodes 6 is connected to the arched steel frame 1 via four spring-type energy-dissipating devices 7, and the outer surface of the grid support structure is covered with an elastic energy-dissipating flexible protective layer.
[0046] like Figures 1 to 7 As shown, in this embodiment, the energy-dissipating and vibration-damping node 6 includes an outer plate layer, a rubber pad layer, and an inner plate layer. The inner surface of the outer plate layer has a first channel matching the longitudinal steel wire rope 4. The longitudinal steel wire rope 4 is sleeved inside the first channel (the longitudinal steel wire rope 4 and the first channel can be interference-fitted, or the portions of the longitudinal steel wire rope 4 at both ends of the first channel can be fixed with clamps to prevent relative movement between the longitudinal steel wire rope 4 and the first channel). The outer surface of the outer plate layer has a second channel matching the transverse steel wire rope 5. The transverse steel wire rope 5 is sleeved inside the second channel (the transverse steel wire rope 5 and the second channel can be interference-fitted, or the portions of the transverse steel wire rope 5 at both ends of the second channel can be fixed with clamps to prevent relative movement between the transverse steel wire rope 5 and the first channel). The first channel and the second channel are perpendicular to each other. The outer plate layer and the inner plate layer are fixed together by bolts to hold the rubber pad layer. The outer surface of the inner plate layer has four first connecting holes, and each first connecting hole is perpendicular to the two lines connecting its adjacent two first connecting holes.
[0047] The outer side of the support frame is provided with multiple sets of connecting components that are equally spaced along the arch direction. Each set of connecting components consists of two connecting lugs 9, and each connecting lug 9 is provided with a second connecting hole.
[0048] The four first connection holes on any one of the energy-dissipating and vibration-damping nodes 6 are respectively connected to a corresponding second connection hole on the four connecting lugs 9 through four adjacent spring-type energy-dissipating devices 7.
[0049] like Figures 1 to 7 As shown, in this embodiment, the elastic energy-dissipating flexible protective layer includes a flexible protective mesh group 8, which includes a ring mesh and a grid mesh. The ring mesh covers the outside of the grid support structure, and the grid mesh covers the outside of the ring mesh.
[0050] like Figures 1 to 7 As shown, in this embodiment, the aperture of the annular mesh is larger than the aperture of the grid mesh. The apertures of both the annular mesh and the grid mesh are selected based on actual conditions to address the problem of this invention.
[0051] Working principle:
[0052] When falling rocks or other debris impact the protective shelter, protection and shock absorption are achieved through a coordinated mechanism of "multi-layered interception - progressive energy dissipation - elastic force relief." The specific process is as follows:
[0053] Outer layer interception: The first contact is with the flexible protective mesh (based on actual conditions, the mesh is made of existing mature and molded materials with sufficient strength to withstand large falling rocks without breaking, thus solving the problem of this utility model). For example, GTC-65A / B, with a mesh size of 65×65mm (much smaller than the 300mm of a ring mesh), wire diameter of 3.0mm; tensile strength ≥1770MPa; equipped with Φ16 support rope + Φ8 stitching rope, preferentially intercepting particles with a diameter ≤50mm. For example, gabion mesh (60×80mm), with a mesh size of 60×80mm and a wire diameter of 2.5-3.0mm, features a double-twisted hexagonal structure with a certain degree of flexibility, suitable for intercepting small gravel (particle size ≤60mm), and its structural flexibility can work in conjunction with energy-consuming nodes for buffering. Another example is gabion mesh (100×120mm), with a mesh size of 100×120mm and a wire diameter of 3.0mm; it has excellent corrosion resistance and is suitable for intercepting gravel with a particle size ≤80mm, applicable to scenarios where the gravel particle size is slightly larger but penetration needs to be avoided. In practical applications, it is easily broken by large falling rocks, causing the entire protective layer to fail, and the technical solution cannot achieve the expected protective effect. This method utilizes its small aperture characteristics to intercept smaller gravel, preventing small falling objects from penetrating the protective layer; small gravel will be directly bounced off.
[0054] Secondary interception and force transmission: Larger boulders are intercepted by the grid mesh (which deforms upon impact) and the underlying ring mesh (the ring mesh is made of readily available, mature materials with sufficient strength to address the problem of this invention, depending on the specific circumstances). For example, the existing RXI-075 (R7 / 3 / 300) has a 300mm mesh size, 3mm wire diameter, and 7 coils of wire per ring; it intercepts impact energy ≤750kJ; equipped with double support ropes and multiple energy dissipation rings, it enhances impact resistance redundancy and is suitable for complex slopes in scenarios involving medium to large boulders (e.g., single boulders weighing ≤15t). Another example is the RXI-100 (R9 / 3 / 300), with a 300mm mesh size, 3mm wire diameter, and 9 coils of wire per ring. The structure features a ring network; the interception impact energy is ≤1000kJ; reinforced support rope configuration further enhances structural stability in high-impact risk scenarios (such as steep slopes and areas prone to large rockfalls). The impact load is then evenly transferred from the grid mesh and ring mesh to the grid support structure composed of longitudinal and transverse steel wire ropes behind it.
[0055] Multi-stage energy dissipation and buffering: The force on the grid support structure is dispersed through energy dissipation and damping nodes at each intersection. The rubber pad layer inside the node first absorbs part of the impact force, achieving initial buffering. Then, the impact force is transmitted to four spring-type energy dissipation devices connected to the node (i.e., springs with energy dissipation effect in existing mature technology, the model of which can be selected according to the actual situation). The springs further dissipate the impact energy through elastic deformation. Finally, under the reaction force, the falling rocks roll to the outside of the shed, reducing the accumulation of falling rocks on the top of the shed and reducing the long-term load-bearing risk of the structure. At the same time, the synergistic effect of the springs and nodes optimizes the force distribution of the entire shed system and improves the seismic and impact resistance stability.
[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
