Description

Technical Field

[0001] This utility model relates to the field of slope management, and to a modular canopy connection structure. This canopy structure is used in steep slope sections in plateau and mountainous areas, and can quickly carry out construction and repair of damaged canopy sections. Background Technology

[0002] Steep slopes in high-altitude mountainous regions make them prone to natural disasters such as torrential rains, floods, landslides, and earthquakes. The complex geological structures further exacerbate the instability of steep slopes, increasing the risk of collapses and landslides. Snowstorms and avalanches are also common in winter, posing significant challenges to road operation and construction. Constructing tunnel structures on the road surface can protect against rockfalls, greatly reducing the risk of rockfalls, landslides, and avalanches.

[0003] Most existing shed structures require on-site casting, directly using steel plates as the shed roof slab. The roof slab is fixedly connected to the supporting side walls. This connection method cannot provide cushioning and shock absorption, making it easily damaged after long-term exposure to falling rocks, thus affecting its service life. Furthermore, once the roof slab is damaged, it cannot be repaired promptly.

[0004] The repair cycle and construction procedures are quite difficult. Summary of the Invention

[0005] This utility model addresses the shortcomings of existing technologies by providing a modular shed connection structure. This connection structure can buffer the structure at the top, thereby mitigating the vertical forces generated by falling rocks, avalanches, and other impacts, and protecting the bottom support surface of the entire shed structure. Furthermore, the main beam of the shed roof and the supporting wall are connected by a modular assembly method, which allows for quick assembly, easy installation and disassembly, and convenient maintenance.

[0006] To achieve the above technical objectives, this utility model provides a modular scaffolding connection structure for connecting the main beam of the scaffolding to two supporting side walls. The connection structure includes an elastic connection structure on one side of the main beam and a rotating support on the other side. One end of the main beam is connected to the first supporting side wall via the elastic connection structure, and the other end is connected to the second supporting side wall via the rotating support. The elastic connection structure includes a protruding support at the bottom of the main beam and a spring damping support installed on the top of the first supporting side wall. The spring damping support has a matching insertion groove, and the protruding support is inserted into the insertion groove of the spring damping support. The rotating support is an arc-shaped support fixed to the bottom of the main beam. A corresponding rotating support is provided on the top surface of the second supporting side wall. An arc-shaped groove is formed in the rotating support, and an arc-shaped concave steel plate matching the rotating support is installed in the groove. The rotating support is embedded in the corresponding groove and can rotate within the groove.

[0007] The preferred technical solution of this utility model is as follows: The spring damping support includes a frame structure and damping springs. The frame structure consists of an outer frame and an inner support frame. The outer frame is a concave frame with an open bottom surface, and its concave area forms an insertion groove that matches the convex support. The inner support frame is a square frame with an open top surface. The inner support frame is fixed to the top surface of the second support side wall. Multiple sets of vertical damping springs are provided inside the inner support frame. The outer frame is fitted onto the open surface of the inner support frame, and the tops of the multiple sets of damping springs are connected to the outer frame. The side baffles of the inner support frame and the side baffles of the outer frame are connected by a sliding adjustable snap-fit ​​assembly.

[0008] The preferred technical solution of this utility model is that the bottom corner of the convex support is an arc-shaped surface.

[0009] The preferred technical solution of this utility model is as follows: The buckle assembly includes an upper buckle welded to the inner support frame, a lower buckle welded to the outer frame, and a bolt connecting the two buckles. The upper buckle has multiple bolt holes evenly distributed, and the lower buckle has a vertical adjustment hole. The bolt is fixed in the corresponding bolt hole, and the other end extends into the vertical adjustment hole. Under the action of the shock-absorbing spring, when the outer frame moves up and down, the bolt moves up and down along the vertical adjustment hole.

[0010] The preferred technical solution of this utility model is as follows: multiple sets of lateral buffer springs are provided between the side baffle of the inner support frame and the side baffle of the recessed area of ​​the outer frame.

[0011] The side retaining wall of this utility model is designed as a precast component with a convex reinforced concrete structure at its lower end. A magnet is embedded at the bottom of the convex shape, which is intended to attract magnetic concrete material during rapid installation on the construction site and also facilitates quick maintenance and replacement later. Magnetic anchor rods with enlarged ends are passed through pre-drilled holes in the wall body to connect with the conical retaining wall for magnetic concrete pouring, which is intended to improve the lateral support of the side retaining wall. A rotating support is set at the top of the side retaining wall to facilitate its connection with the rotating support of the main beam. The modular prefabrication and installation facilitate faster and more convenient maintenance later.

[0012] In this utility model, precast bearing piles are driven into the bearing layer of the foundation in the external support structure, and the top is connected to the bearing pile platform roadbed. This is to better and more evenly transfer the vertical load to the bearing layer of the foundation. Magnetic expanded head anchors are driven into the bearing layer of the foundation at an angle of 30 to 60 degrees, and the other end of the magnetic expanded head anchors is connected to the bearing pile platform roadbed. This is to improve the lateral bearing capacity of the bearing pile platform roadbed. A steel mesh is suspended on the suspended side of the bearing pile platform roadbed, and foam fiber concrete is sprayed for protection. This is to protect the slope from rainwater erosion and provide a certain lateral bearing capacity to the slope. The foam fiber concrete is composed of foaming agent, water, ordinary Portland cement, fine sand, and steel fiber.

[0013] The snap-fit ​​assembly of the spring damping device of this utility model can be divided into upper and lower parts, which is beneficial to provide displacement distance for vertical movement; the lower end of the pressure spring is placed on the spring support of the outer frame and the upper end is fastened to the spring support of the inner support frame. The purpose is to use the elastic force of the spring to facilitate the vertical movement of the spring when the entire device is subjected to vertical load; the side buffer spring is placed on the side position to facilitate the buffering of lateral movement of the device. The main beam of this invention has a rotating support at the lower part and a cable-fixed support at the upper part at one end, which is intended to provide a certain rotational displacement when the main beam is displaced; the other end has a spring support at the lower part and a cable-fixed support at the upper part, which is intended to provide a certain vertical buffer displacement when the main beam is subjected to vertical load, so as to reduce the impact force on the structure; the steel reinforcement skeleton of the module flip beam is intended to reduce the impact on the clearance of the opening; the installation of a beam bottom pad and cable at the bottom of the beam is intended to improve the bending resistance of the main beam; the cable passes through the reserved hole in the beam bottom pad, then passes through the beam side pad and around to the cable-fixed support at the beam end, and is fixed by the clamps, which is intended to improve the load-bearing capacity of the main beam.

[0014] The beneficial effects of this utility model are:

[0015] This utility model designs a spring-loaded shock-absorbing support to provide energy reduction and buffering capabilities for the tunnel, thereby buffering the vertical forces generated by impacts such as falling rocks and avalanches, and protecting the bottom support surface of the entire tunnel structure; in addition, the main beam of the tunnel roof and the supporting wall are connected by an assembly method, which can be quickly assembled, installed and disassembled, and facilitates rapid repair and replacement after the tunnel is damaged.

[0025] The embodiment provides a modular scaffolding connection structure for connecting the main beam 1 of the scaffolding to the two supporting side walls, such as... Figures 1 to 6 As shown, the connection structure includes an elastic connection structure on one side of the main beam 1 and a rotating support 4 on the other side of the main beam 1. One end of the main beam 1 is connected to the first supporting side wall 2 through the elastic connection structure, and the other end is connected to the second supporting side wall 3 through the rotating support 4. The elastic connection structure includes a protruding support 5 at the bottom of the main beam 1 and a spring damping support 6 installed at the top of the first supporting side wall 2. The spring damping support 6 is provided with a matching insertion groove 600 for the protruding support 5. The protruding support 5 is inserted into the insertion groove 600 of the spring damping support 6. The bottom corner of the protruding support 5 is arc-shaped. The rotating support 4 is an arc-shaped support fixed to the bottom of the main beam 1 of the scaffold. A rotating support 7 is provided on the top surface of the second support side wall 3. An arc-shaped groove 700 is provided in the rotating support 7, and an arc-shaped concave steel plate 701 matching the rotating support 4 is installed in the groove 700. The rotating support 4 is embedded in the corresponding groove 700 and can rotate in the groove 700.

[0026] An example of a modular scaffolding connection structure is provided in the embodiment, such as... Figure 2 and Figure 4As shown, the spring damping support 6 includes a frame structure 601 and a damping spring 602. The frame structure 601 consists of an outer frame 6021 and an inner support frame 6022. The outer frame 6021 is a concave frame with an open bottom. The spring damping support 6 is provided with a insertion groove 600 that matches the convex support 5. The inner support frame 6022 is a square frame with an open top. The inner support frame 6022 is fixed to the top surface of the second support side wall 3. The frame 6022 has multiple sets of vertical shock-absorbing springs 602 inside. The outer frame 6021 is fitted onto the open surface of the inner support frame 6022. The tops of the multiple sets of shock-absorbing springs 602 are connected to the outer frame 6021. A lateral buffer spring 603 is provided between the side baffle of the inner support frame 6022 and the side baffle of the recessed area of ​​the outer frame 6021. The side baffle of the inner support frame 6022 and the side baffle of the outer frame 6021 are connected by a snap-fit ​​assembly 604. Figure 5 and Figure 6 As shown, the buckle assembly 604 includes an upper buckle 6041 welded to the inner support frame 6022, a lower buckle 6042 welded to the outer frame 6021, and a bolt connecting the two buckles.

[0027] In practical use, one end of the main beam 1 of the scaffold is inserted into the corresponding groove 700, and the other end is inserted into the insertion groove 600 of the spring damping support 6. After the main beam 1 of the scaffold is spliced, a support plate is installed between two adjacent main beams 1 of the scaffold. The support plate can be fixed by bolts, or the support plate can be integrated with the main beam 1 of the scaffold and then assembled with the support side wall.

[0028] This utility model features a spring connection structure at one end, which helps provide a certain vertical buffer displacement when the main beam 1 of the scaffold is subjected to vertical loads, thereby reducing the impact force on the structure. The snap-fit ​​assembly of the spring damping support 6 can be divided into upper and lower parts, which helps provide vertical displacement distance. Placing the lower end of the bearing spring on the spring support of the outer frame and the upper end on the spring support of the inner bearing frame utilizes the spring force to facilitate the vertical movement of the spring when the entire device is subjected to vertical loads. The side buffer spring is placed on the side to help buffer the lateral movement of the device. The rotating support 4 at the other end of the main beam 1 cooperates with the rotating support 7, which helps provide a certain rotational displacement when the main beam 1 of the scaffold is displaced.

[0029] The above description is merely one embodiment of this utility model, and while it is quite specific and detailed, it should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
