Description

Technical Field

[0001] This utility model relates to the field of scaffolding erection technology, and in particular to a slope-connecting structure for horizontal crossbars of scaffolding on a slope surface. Background Technology

[0002] Slope protection engineering is a common construction component during railway line construction. In railway line operation and maintenance, slope management and maintenance are crucial for ensuring operational safety. Due to the characteristics of high slopes along operating railway lines, such as steep gradients, poor surface smoothness, limited scaffolding width, large height-to-width ratios, and higher safety and stability requirements, a step-by-step, slope-adjusting scaffolding erection method is typically adopted. This method ensures sufficient working space while guaranteeing the safety and stability of the scaffolding and the railway's operational safety. When the cantilever length of horizontal crossbars is long, reliable crossbar anchorage nodes must be installed to ensure the safety and stability of the personnel working plane and the scaffolding itself. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a structure for connecting horizontal crossbars of scaffolding on a slope.

[0004] This utility model provides a horizontal crossbar connecting component structure for scaffolding on a slope surface, including: an anchor rod, the first end of which is embedded in the slope body and the second end of which extends out of the slope surface; The connecting rod has its first end connected to the second end of the anchor rod via a universal hinge assembly. The second end of the connecting rod is horizontally fixed to the end of the horizontal crossbar of the scaffold. The rod end joint bearing is equipped with a locking assembly, which is used to lock the relative rotation between the anchor rod and the connecting rod.

[0005] Optionally, the anchoring section of the anchor rod is threaded, and the connecting rod surface is smooth.

[0006] Optionally, the anchoring depth of the anchor rod within the slope shall not be less than 500mm.

[0007] Optionally, the second end of the connecting rod overlaps with the end of the horizontal crossbar of the scaffold to form an overlapping section, which is fixedly connected by at least two fasteners.

[0008] Optionally, the distance between the fasteners on both sides and the second end of the connecting rod or the end of the horizontal crossbar of the scaffold should not be less than 100mm.

[0009] Optionally, the angle between the anchor rod and the slope surface normal is 30° to 45°.

[0010] Optionally, the diameter of the connecting rod is equal to the diameter of the horizontal bar.

[0011] Optionally, the locking assembly includes a pair of locking lugs and a locking bolt; the locking lugs are respectively fixedly connected to the second end of the connecting rod and the first end of the anchor rod.

[0012] The technical solution provided by this utility model has the following advantages compared with the prior art: This utility model inserts the first end of the anchor rod, i.e., the anchor section, into the slope to ensure it reaches the designed depth. Next, one end of the rod end spherical bearing is firmly connected to the second end of the anchor rod extending out of the slope. Then, the first end of the connecting rod is connected to the other end of the rod end spherical bearing. After this step, a flexible joint capable of multi-directional rotation is formed between the anchor rod and the connecting rod. Finally, the second end of the connecting rod is horizontally fixed to the end of the horizontal crossbar of the scaffold, thus completing the installation of the entire connecting component. The first end of the anchor rod is embedded in the slope body to provide a stable foundation for the whole structure. The second end extends out of the slope surface and is flexibly connected to the first end of the connecting rod through the rod end joint bearing. This effectively adapts to the irregular changes in the slope surface and avoids the additional stress caused by rigid connection. At the same time, the second end of the connecting rod is directly fixed to the end of the horizontal crossbar of the scaffold, reliably transferring the load of the scaffold to the stable slope through the anchor rod. Thus, while ensuring the connection strength and overall stability, it achieves an effective connection between the scaffold and the slope, significantly enhancing the integrity and safety of the scaffold under complex slope conditions.

[0014] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0015] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the technical solution of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] The present invention will be described below through several specific embodiments. To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and components may be omitted. When any component of an embodiment of the present invention appears in more than one drawing, the component may be represented by the same reference numerals in each drawing.

[0017] like Figure 1 As shown, this utility model embodiment provides a slope-connecting structure for a horizontal crossbar 6 of a scaffold on a slope 5, comprising: an anchor rod 1, the first end of which is embedded in the slope 5 and the second end of which extends out of the slope surface; a connecting rod 2, the first end of which is connected to the second end of the anchor rod 1 via a rod end joint bearing 3; the second end of the connecting rod 2 is horizontally fixedly connected to the end of the horizontal crossbar 6 of the scaffold, and the rod end joint bearing 3 is provided with a locking component, which is used to lock the relative rotation between the anchor rod 1 and the connecting rod 2.

[0018] Specifically, the fixed end of the rod end spherical bearing 3 is fixedly connected to the end of the anchor rod 1 extending out of the slope, and the rotating end is rotatably connected to the first end of the connecting rod 2. This effectively connects the end of the horizontal crossbar 6 of the scaffold to the deep, stable slope 5. The anchor rod 1, deeply embedded in the slope, provides reliable pull-out anchoring force, while the rod end spherical bearing 3 grants the connection node a certain degree of rotational freedom in three-dimensional space, actively adapting to possible minor settlement, slippage, or rotational deformation of the slope 5. This effectively releases the resulting additional stress and avoids the twisting of connectors, weld cracking, or scaffold instability that can easily occur with traditional rigid connection methods. This improves the adaptability and safety redundancy of the scaffold support system on complex geological slopes 5, ensures the overall stability of the construction platform, and reduces the risk of safety accidents caused by slope deformation. The flexible connection mechanism reduces structural damage to the scaffold and connectors themselves, extends the service life of reusable materials, simplifies installation and adjustment procedures, and improves construction efficiency. Based on this core concept, this solution can be further extended to temporary support or permanent auxiliary structure anchoring scenarios with high requirements for deformation adaptability, such as tunnel sidewalls, irregular cliffs, and between support piles, and has broad promotional value.

[0019] Optional, see reference Figure 1 The anchoring section of anchor rod 1 is threaded, while the surface of connecting rod 2 is smooth.

[0020] Specifically, the surfaces of connecting rod 2 and scaffold steel pipes are kept smooth. When connected to standard fastener 4, the increased smooth contact surface ensures that the inner wall of fastener 4 fully fits the outer wall of the rod, generating uniform friction after tightening the bolts. This makes the connection between connecting rod 2 and scaffold more secure, effectively preventing relative slippage. Simultaneously, the anchoring section of anchor rod 1 is threaded. Through the mechanical engagement of the threads with the grout or soil, the bond strength and frictional resistance between the anchor rod 1 and the slope 5 soil and rock mass are enhanced, improving the pull-out resistance of anchor rod 1. The mechanical properties of the rods at the structural connection and the soil-rock anchoring end are optimized, jointly ensuring the reliability of the overall slope connection structure. Based on this surface treatment logic, this scheme can be further expanded. For example, threads can be added to specific sections of connecting rod 2 to allow for stepless adjustment of the connection length with threaded nut sleeves; or, when subjected to huge loads, a better ribbed or wave-shaped thread design can be considered for the anchoring section to further maximize its anchoring force.

[0021] Optional, see reference Figure 1 The anchoring depth of anchor rod 1 within slope 5 shall not be less than 500mm.

[0022] Specifically, the anchoring depth of anchor rod 1 is no less than 500 mm. Sufficient anchoring length allows the gripping force of anchor rod 1 to fully develop, effectively transferring and distributing the scaffolding load it bears to the deeper, more stable slope soil and rock mass 5, thereby avoiding the risk of pull-out failure due to insufficient stability of the shallow soil. This enhances the safety reserve and reliability of anchor rod 1, providing a solid foundation for the upper scaffolding system.

[0023] Optional, see reference Figure 1 The second end of the connecting rod 2 overlaps with the end of the horizontal crossbar 6 of the scaffold to form an overlapping section, which is fixedly connected by at least two fasteners 4.

[0024] In this optional scheme, the connecting rod 2 and the horizontal crossbar 6 of the scaffold are connected by overlapping side-by-side and fixed by fasteners 4. The overlapping section creates a local rigid connection node, and at least two fasteners 4 form multi-point constraints, ensuring reliable torque transmission and the integrity of the connection. This creates a stable and clearly defined force transmission path, effectively resisting potential lateral instability and torsional deformation of the scaffold. Compared to welding or single bolt connections, the use of standardized fasteners 4 gives this connection significant advantages such as rapid installation, high adjustability, and reusability, greatly improving the convenience and economy of construction.

[0025] Optional, see reference Figure 1 The distance between the fasteners 4 on both sides and the second end of the connecting rod 2 or the end of the water balance rod shall not be less than 100mm.

[0026] Specifically, the effective overlap length is no less than 500mm to provide sufficient contact area, thereby ensuring that the connecting rod 2 and the horizontal crossbar 6 of the scaffold generate sufficient friction in the overlapping section to meet the key mechanical requirements of transmitting horizontal loads and resisting lateral slippage. Both sides of the coupler 4 retain a minimum of 100mm of clearance from the rod end, avoiding localized stress concentration and crushing deformation that might occur if the coupler 4 is too close to the rod end edge. This improves the strength and durability of the connection node, provides a clear positioning benchmark for actual construction, ensures that structural requirements are accurately implemented, and reduces quality risks caused by operational deviations.

[0027] Optional, see reference Figure 1 The angle between anchor rod 1 and the slope surface normal of slope 5 is 30° to 45°.

[0028] Specifically, the inclination angle of anchor rod 1 is within the range of 30° to 45°. Inserting anchor rod 1 at a moderately downward angle allows its axis to be closer to the actual force direction caused by the scaffold load, thus ensuring that anchor rod 1 primarily bears tensile force and fully utilizes its tensile material properties. This effectively reduces the bending moment component inside anchor rod 1, improves its force transmission efficiency and load-bearing capacity, and reduces the risk of premature anchoring system failure due to improper force direction.

[0029] Optional, see reference Figure 1 The diameter of connecting rod 2 is equal to the diameter of the horizontal crossbar 6 of the scaffold.

[0030] Specifically, the diameter of connecting rod 2 is consistent with the diameter of the horizontal crossbar 6 of the scaffolding, utilizing the structural characteristics of the standard coupler 4. Since the two holes of a coupler 4 have the same diameter and its adjustment range is extremely limited, designing the two parallel overlapping rods to have the same diameter ensures that they can achieve maximum area of ​​tight contact with the inner wall of the coupler 4. When tightening the bolts, the coupler 4 can apply a uniform and sufficient clamping force to the two rods, thereby generating maximum and stable frictional force in the overlapping section, effectively ensuring smooth force transmission and avoiding problems such as loose engagement, stress concentration, or connection slippage caused by diameter mismatch. This improves the rigidity and reliability of the node connection.

[0031] At the designed location on slope 5, holes are drilled at a predetermined angle. After cleaning the holes, high-strength cement grout or chemical anchoring adhesive is injected. Then, the first end of anchor rod 1, i.e., the anchor section, is inserted into the hole, ensuring it reaches the designed depth and is centered within the hole. After the anchoring material reaches its designed strength, subsequent operations are performed. Next, one end of the rod end bearing 3 is securely connected to the second end of anchor rod 1 extending from the slope. If rod end bearing 3 is used, it is directly screwed onto the thread at the end of anchor rod 1. Then, the first end of connecting rod 2 is connected to the other end of rod end bearing 3. After this step, a flexible joint capable of multi-directional rotation is formed between anchor rod 1 and connecting rod 2. Finally, the second end of connecting rod 2 is horizontally fixed to the end of the scaffold horizontal crossbar 6, thus completing the installation of the entire connector. The self-weight of the scaffold and the horizontal force generated during construction are transmitted through the scaffold horizontal crossbar 6 to connecting rod 2, then through rod end bearing 3 and anchor rod 1, and finally safely diffused into the stable soil and rock mass of slope 5.

[0032] Optional, see reference Figure 1 The locking assembly includes a pair of locking lugs and a locking bolt; the locking lugs are respectively fixedly connected to the second end of the connecting rod 2 and the first end of the anchor rod 1.

[0033] When the connecting rod 2 is rotated to the target angle, the through holes on the pair of locking lugs align and are locked in place by the locking bolts. When the connecting rod 2 is rotated to be horizontal with the horizontal crossbar 6 of the scaffold, the through holes on the pair of locking lugs will align. At this point, the locking bolts can be inserted and the nuts tightened to rigidly connect the anchor rod 1 and the connecting rod 2, locking the joint bearing and preventing subsequent rotation.

[0034] The above-described embodiments are merely a few specific examples of this utility model. However, the embodiments of this utility model are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
