Description

Technical Field

[0001] This application relates to the technical field of scaffolding, and particularly to a multi-angle and telescopic button-connected scaffolding group. Background Art

[0002] The button-connected scaffolding is a scaffolding system composed of steel pipes as raw materials, with vertical poles, cross bars and other components connected by eight-hole button joints. Its design is ingenious. The cross bar and the vertical pole are fixed by a pin, ensuring the structural stability; the joint adopts an eight-hole disc type, and the pin fixing method is convenient for quick assembly and disassembly, improving the construction efficiency. This kind of scaffolding not only has strong bearing capacity and can meet the construction requirements of various building structures.

[0003] At present, due to the diversification of building forms and the increasing requirements of modern people for indoor space, the indoor space layout is no longer limited to a square layout, but has a building form with personality and characteristic shapes. To meet the personalized appearance and usage functions of the building, the beams and columns of such buildings are almost all obliquely intersecting.

[0004] When the mainstream button-connected scaffolding on the market is used as a support system, it is only applicable to rooms with a ninety-degree orthogonal intersection and fixed modules. For the connection between vertical poles in non-fixed module rooms and rooms with obliquely intersecting beams, the distances between the bottom vertical poles in the non-fixed module area and between the bottom vertical poles of the slab and the bottom vertical poles of the beam are special, resulting in the inability to use the built button-connected scaffolding for connection and support. Usually, the steel pipe and the cross bar of the button-connected scaffolding are connected by a cross buckle. In this case, the connection node at the cross buckle becomes a semi-rigid connection, and the cross bar is forced to bear shear force and bending moment, and stress concentration occurs at the cross buckle of the cross bar, which may cause the cross bar to deform or the cross buckle node to slip, greatly reducing the stability and safety of the button-connected scaffolding. Summary of the Invention

[0005] In order to improve the problem of reduced stability when the button-connected scaffolding is used in non-fixed module rooms or rooms with obliquely intersecting beams, this application provides a multi-angle and telescopic button-connected scaffolding group.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0024] An embodiment of the present application discloses a multi-angle and telescopic socket-type scaffolding group. Refer to Figure 1 , the multi-angle and telescopic socket-type scaffolding group includes: The basic scaffolding group 1 includes vertical poles 11, basic disk buttons 12 arranged on the vertical poles 11, and crossbars 13 connected to the basic disk buttons 12; a connector 2 is arranged at the end of the crossbar 13. The connector 2 is a wedge pin connector commonly used in existing disk button scaffolds (the same hereinafter). The connector 2 is provided with a clamping groove for inserting the disk button along the transverse direction and a pin hole for inserting a pin along the longitudinal direction. The crossbar 13 is connected to the basic disk button 12 by passing a pin through the pin hole of the connector 2 and the side hole of the basic disk button 12; and An adjustable connection mechanism is arranged between two groups of basic scaffolding groups 1 and is used to connect two basic disk buttons 12; The adjustable connection mechanism includes a telescopic connecting rod 4 and two angle adjusting devices 3 respectively arranged at both ends of the telescopic connecting rod 4. The telescopic connecting rod 4 is connected to the basic disk button 12 in an angle-adjustable manner through the angle adjusting device 3.

[0025] When it is necessary to build a scaffold in a room with non-fixed modulus or skew beams, it is difficult to connect two basic disk buttons 12 in the non-fixed modulus area with a crossbar 13 of fixed modulus. In this application, by designing an adjustable connection mechanism, it is directly connected to two basic disk buttons 12 with special spacings. Through angle and telescopic adjustment, the adjustable connection mechanism can infinitely adapt to two basic disk buttons 12 with special spacings, solving the problem that the crossbar 13 is prone to stress concentration and the structural stability is reduced when the steel pipe is connected with a cross-shaped buckle on the crossbar 13.

[0026] Specifically, please refer to Figure 2 The angle adjusting device 3 includes a connecting pipe 31, a movable disk button 32 and a locking member.

[0027] In order to realize the angle-adjustable connection between the telescopic connecting rod 4 and the basic disk button 12, the connecting pipe 31 is designed in an L shape. Specifically, the connecting pipe 31 includes an integrally formed arc section 311, a first end pipe 312 and a second end pipe 313. The first end pipe 312 and the second end pipe 313 are arranged at both ends of the arc section 311 and are perpendicular to each other. A connecting head is welded and fixed at the end of the first end pipe 312 and is connected to the basic disk button 12 through the connector 2. The movable disk button 32 is connected to the second end pipe 313 in an angle-adjustable manner. The movable disk button 32 adopts the same design and principle as the basic disk button 12, that is, a plurality of side holes for connecting the connector 2 are symmetrically arranged on the periphery of the movable disk button 32. Connecting heads 2 are welded and fixed at both ends of the telescopic connecting rod 4 and are locked with the movable disk button 32 through the connecting heads 2 and pins. The locking member is used to lock or release the movable disk button 32.

[0028] Thus, the connecting pipe 31, the telescopic connecting rod 4, and the base socket 12 are all connected by the existing mature socket connection method to ensure the stability of the adjustable connection mechanism. The connecting pipe 31 at a right angle serves as a transition connecting piece, cooperating with the threaded section 33 and the locking nut 34 to ensure the rotational setting and locking of the movable socket 32, realizing the stepless adjustment of the angle of the telescopic connecting rod 4 within a large range, and further improving the applicability of the scaffolding set of the present application.

[0029] Moreover, a haunch piece 36 is welded and fixed inside the connecting pipe 31. The haunch piece 36 is a triangular steel sheet, and the haunch piece 36 is welded and fixed on the connecting pipe 31 and covers the arc section 311, the first end pipe 312, and the second end pipe 313 to greatly improve the anti-deformation ability of the connecting pipe 31, and thus effectively improve the stability of the socket-type scaffolding set of the present application.

[0030] Furthermore, in order to facilitate locking the movable socket 32 on the connecting pipe 31 and allowing the angle adjustment of the movable socket 32, a threaded section 33 is provided at one end of the second end pipe 313 away from the arc section 311. The diameter of the threaded section 33 is smaller than the diameter of the second end pipe 313. And, an inner hole for the threaded section 33 to pass through is provided in the middle of the movable socket 32, and the diameter of the inner hole is smaller than the diameter of the second end pipe 313, so that the movable socket 32 can be sleeved on the threaded section 33 and abutted against the end of the second end pipe 313. For this, the locking member is set as the locking nut 34. The locking nut 34 is threadedly connected with the threaded section 33. By rotating the locking nut 34, the locking nut 34 is moved closer to the movable socket 32 until it abuts tightly against the movable socket 32, so that the movable socket 32 abuts tightly against the second end pipe 313 and an axial pressing force is generated to realize the locking of the angle of the movable socket 32.

[0031] In addition, still referring to Figure 2 , an axial sleeve is integrally formed coaxially on one side of the movable socket 32 away from the second end pipe 313. The threaded section 33 can pass through the axial sleeve. A magnetic adsorption positioning piece 35 is adhesively fixed on the side wall of the axial sleeve. The magnetic adsorption positioning piece 35 is a permanent magnet. The central plane of the magnetic adsorption positioning piece 35 is coplanar with the midline plane of one of the side holes. The number of the magnetic adsorption positioning pieces 35 is the same as the number of the side holes of the movable socket 32. In this embodiment, four magnetic adsorption positioning pieces 35 are provided. The connecting head 2 is made of magnetic metal. When the connecting head 2 at the end of the telescopic connecting rod 4 is connected to the movable socket 32, the magnetic adsorption positioning piece 35 can generate a certain adsorption force on the connecting head 2, facilitating the staff to quickly position the connecting head 2 at the end of the telescopic connecting rod 4 and the side holes on the movable turntable, realizing quick positioning.

[0032] On the other hand, the telescopic connecting rod 4 includes a first connecting rod 41 and a second connecting rod 42. For details, please refer to Figure 3, the first connecting rod 41 and the second connecting rod 42 are coaxially arranged, and connectors 2 are welded and fixed to the ends far away from each other. One end of the first connecting rod 41 close to the second connecting rod 42 is sealed and provided with an external thread, and one end of the second connecting rod 42 close to the first connecting rod 41 is provided with a connecting groove for the first connecting rod 41 to penetrate, and the inner wall of the connecting groove is provided with an internal thread. The first connecting rod 41 and the second connecting rod 42 realize the telescopic adjustment of the telescopic connecting rod 4 by adjusting the amount of thread fit.

[0033] Among them, the first connecting rod 41 and the second connecting rod 42 can be directly thread-fitted, and the structure is relatively simple. However, since the card slot of the connector 2 needs to be in the horizontal position to be inserted into the movable buckle 32, the first connecting rod 41 and the second connecting rod 42 need to rotate 180° relative to each other to realize the connection between the connector 2 and the movable buckle 32, so that the distance between the two base buckles 12 adapted by the telescopic connecting rod 4 is a stepped size rather than a continuous size. In order to realize the stepless adjustment of the telescopic connecting rod 4, in another embodiment, a transition adjustment device is provided between the first connecting rod 41 and the second connecting rod 42. The transition adjustment device is used to ensure that when the telescopic connecting rod 4 is at any length within the adjustable range, the connectors 2 at the ends of the first connecting rod and the second connecting rod can be connected to the corresponding movable buckles 32.

[0034] Specifically, please refer to Figure 4 , the transition adjustment device adopts an adjustment cylinder 44. The inner wall of the adjustment cylinder 44 is provided with an internal thread, the outer wall is provided with an external thread, the inner wall diameter is adapted to the outer diameter of the first connecting rod 41, and the outer wall diameter is adapted to the inner wall diameter of the connecting groove of the second connecting rod 42. A limiting ring with a diameter larger than that of the adjustment cylinder 44 is integrally formed at one end of the adjustment cylinder 44 away from the second connecting rod 42. The limiting ring can be made into a regular hexagon to facilitate the rotation of the adjustment cylinder 44.

[0035] In the specific implementation process, first connect and fix the connectors 2 of the two connecting pipes 31 to the two base buckles 12 respectively. At this time, the movable buckles 32 on the connecting pipes 31 are all in a movable state. Then insert the first connecting rod 41 into the connecting groove of the second connecting rod 42. At this time, the adjustment cylinder 44 is thread-sleeved on the first connecting rod 41, and the adjustment threaded cylinder is in a non-contact state with the second connecting rod 42. Adjust the positions of the first connecting rod 41 and the second connecting rod 42, and rotate the angles of the two movable buckles 32 so that the connectors 2 at the ends of the first connecting rod 41 and the second connecting rod 42 are respectively fixedly connected to the two movable buckles 32. Then rotate the locking nut 34 to lock the movable buckle 32, and rotate the adjustment cylinder 44 to make the adjustment cylinder 44 move closer to the second connecting rod 42 and be thread-connected to the second connecting rod 42 until the limiting ring abuts against the end of the second connecting rod 42, realizing the locking of the first connecting rod 41 and the second connecting rod 42.

[0036] As an alternative embodiment, the first connecting rod 41 and the second connecting rod 42 can also be inserted and locked with a quick-release locking mechanism such as a cam lock or a lever lock, so that the first connecting rod 41 and the second connecting rod 42 are locked by friction. Although the locking is relatively simple and can also achieve stepless adjustment of the length of the telescopic connecting rod 4, the axial bearing capacity is small and the stability is not high enough.

[0037] In addition, in order to reduce the possibility of loosening between the first connecting rod 41 and the second connecting rod 42, a reinforcement assembly 43 is provided between the first connecting rod 41 and the second connecting rod 42. The reinforcement assembly 43 is used to provide axial forces in opposite directions to the mutually locked first connecting rod 41 and second connecting rod 42.

[0038] Specifically, the reinforcement assembly 43 is arranged in the connection groove of the second connecting rod 42. Both the first connecting rod 41 and the second connecting rod 42 are arranged as steel pipes. The end of the first connecting rod 41 close to the second connecting rod 42 is welded with a steel sheet for sealing treatment, and a steel sheet is welded inside the second connecting rod 42 to form the bottom wall of the connection groove. The reinforcement assembly 43 includes two connecting pieces 431 and a compression spring 432 arranged between the two connecting pieces 431. The two ends of the compression spring 432 are respectively welded and fixed to the two connecting pieces 431. When the first connecting rod 41 and the second connecting rod 42 are thread-locked, the two connecting pieces 431 are pushed by the compression spring 432 to respectively abut against the first connecting rod 41 and the second connecting rod 42, so as to provide axial forces in opposite directions to the first connecting rod 41 and the second connecting rod 42, thereby playing a role in preventing loosening and further improving the stability and safety of the scaffold set of the present application. Moreover, during the actual assembly process, before the adjusting cylinder 44 locks the first connecting rod 41 and the second connecting rod 42, the compression spring 432 can push the first connecting rod 41 and the second connecting rod 42 to move in opposite directions, so that the connecting heads 2 at the ends of the first connecting rod 41 and the second connecting rod 42 are respectively inserted into the two movable disk fasteners 32, so that the telescopic connecting rod 4 adapts to the distance between the two base disk fasteners, achieving the effect of preliminary self-adaptive telescopic quick positioning and facilitating the assembly by the staff.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
