Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a modular scaffolding system and erection method adapted to various sloping spaces. Background Technology

[0002] Currently, modular scaffolding is widely used due to its modular design, high-strength materials, strong load-bearing capacity, and convenient assembly and disassembly. However, the support trays and bolts of modular scaffolding are mostly fixed by vertical welding, which cannot easily adapt to the support of load-bearing frames or work platforms on inclined planes with different inclination angles. The common methods for handling inclined plane conditions are: 1. For small inclinations, the template or platform plate supporting the main beam is usually placed directly on the tray, so that the edge of the tray steel plate bears the force. However, this method is prone to unstable placement of the supporting main beam and local stress damage to the tray and supporting main beam, resulting in the overall collapse of the frame; or wooden (iron) wedges that meet the slope are placed on the tray. However, the manufacturing accuracy of wooden (iron) wedges is difficult to guarantee and they are not easy to fix. At the same time, they are prone to falling off and being missed. Moreover, the "customized" "one solution for one working condition" method consumes a lot of resources. Second, for slopes with large gradients, add a fixed-angle pad with good strength and anti-slip properties under the bottom support to make the uprights of the disc-lock scaffold perpendicular to the inclined plane. These methods are basically "one solution for one working condition", which is expensive and cannot be horizontally connected with the surrounding vertical scaffolds to form a whole, making it difficult to guarantee the overall stability of the scaffold. Summary of the Invention

[0003] The purpose of this invention is to provide a modular frame and erection method that can adapt to various sloping spaces, so as to solve the above-mentioned problems.

[0004] To achieve the above-mentioned objectives, the present invention provides a disc-lock frame adaptable to various sloping spaces, comprising: Rod body; The tray is detachably connected to the rod via a fixing component located in its middle, and at least two gear plates are respectively provided on the bottom surface of the tray on both sides of the fixing component; A number of fixed plates are provided corresponding to the gear plate and connected by a connecting plate. The fixed plate is provided with an arc-shaped part that meshes with the gear plate. The central angle of the arc-shaped part is greater than or equal to 180°. The opening of the arc-shaped part faces upward and is biased towards the direction in which the tray is to be tilted and adjusted, so that one end of the arc-shaped part forms a low end and the other end forms a high end. When the gear plate rotates clockwise from the low end to the high end, the tray tilts at different degrees. The support portion is detachably connected to the rod body, thereby forming a fixed platform below the tray that supports and limits the fixed plate.

[0005] As a further improvement of the present invention, taking the rotation angle of the gear plate as 0 when the tray is horizontal, when the maximum rotation angle of the gear plate is greater than 45°, the angle between the line connecting the high end to the center of the arc-shaped part and the vertical upward direction is 55-60°.

[0006] As a further improvement of the present invention, taking the rotation angle of the gear plate as 0 when the tray is horizontal, when the maximum rotation angle of the gear plate is greater than 45°, the angle between the line connecting the lower end to the center of the arc-shaped part and the vertical downward direction is 75-80°.

[0007] As a further improvement of the present invention, the vertical projections of the center of the arcuate portion and the center of the gear plate coincide.

[0008] As a further improvement of the present invention, the fixing component includes a first snap-fit ​​portion located on the tray, a second snap-fit ​​portion located on the rod body that matches the first snap-fit ​​portion, and a fixing member for fixing the first snap-fit ​​portion and the second snap-fit ​​portion.

[0009] As a further improvement of the present invention, the gear plate is provided with a through hole in the middle for easy installation and inspection of the fixing parts.

[0010] As a further improvement of the present invention, an angle measuring device is provided on the side of the gear plate away from the fixed component.

[0011] As a further improvement of the present invention, the support portion includes a support tray that passes through the rod and a top fastener that is threadedly connected to the rod, the top fastener being located below the support tray and engaging with the support tray.

[0012] As a further improvement of the present invention, the pallet is provided with limiting parts on both sides, and the bottom of the fixing plate is also connected with a pad plate. The width of the lower part of the inclined adjustment structure formed by connecting several fixing plates, pad plates and connecting plates is adapted to the pallet, so that the lower sides of the inclined adjustment structure abut against the limiting parts.

[0013] A method for erecting a modular scaffolding system adaptable to various sloping spaces includes the following steps: S1. Adjust the pallet angle according to the slope angle, and install the pallet on the pole through the fixing components. Then, connect the fixing plates connected by the lacing plates with the corresponding gear plates. S2. The support part is detachably connected to the rod body, and the support part is used to support and limit the gear plate.

[0014] The beneficial effects of this invention are: 1. This invention replaces the vertical welding of existing disc buckle frame trays with a hinged connection formed by fixed components, allowing the disc buckle frame tray to be rotated and adjusted within a certain range as needed to adapt to the support requirements of various sloping spaces. In addition, the meshing connection between the gear plate and the fixed plate, as well as the setting of the support part to support and limit the fixed plate, make the rotational hinge structure between the tray and the rod a statically indeterminate structure. This realizes the transformation from a fixed and non-adjustable disc buckle frame to an adjustable design that can adapt to multiple working conditions, changing the resource waste of "customized" solutions for each working condition, while also ensuring the load-bearing safety of the disc buckle frame.

[0015] 2. This invention connects the gear plate and the fixed plate via an arc-shaped section, with the central angle of the arc being greater than or equal to 180°. This allows for stress redistribution of the pressure on the slope due to the isotropic nature of the circle, thereby transforming the inclined load into a horizontal load and transferring it to the supporting part. The isotropic nature of the circle solves the overturning hazard caused by the eccentric moment generated by the compressive stress on the inclined surface. Furthermore, based on the principle that a circle with equal area has the smallest circumference and that circular shapes save space, the arc-shaped meshing connection design also solves the problem of collisions between components caused by limited rotation space when the pallet rotates at large angles (greater than or equal to 45°).

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0029] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0030] like Figures 1-8 As shown, the present invention provides a disc-lock frame adaptable to various sloping spaces, comprising: Rod 10; The tray 21 is detachably connected to the rod 10 via a fixing component located in its middle. At least two gear plates 23 are also provided on the bottom surface of the tray 21, respectively located on both sides of the fixing component. A number of fixed plates 31 are provided corresponding to the gear plate 23 and connected by a connecting plate 32. The fixed plates 31 are provided with an arc-shaped part 311 that meshes with the gear plate 23. The central angle of the arc-shaped part 311 is greater than or equal to 180°. The opening of the arc-shaped part 311 faces upward and is biased towards the direction in which the tray 21 is to be tilted and adjusted, so that one end of the arc-shaped part 311 forms a low end 313 and the other end forms a high end 312. When the gear plate 23 rotates clockwise from the low end 313 to the high end 312, the tray 21 tilts to different degrees. The support part 40 is detachably connected to the rod 10, so that a fixed platform is formed below the tray 21 to support and limit the fixed plate 31.

[0031] For example, rod 10 is a hinged lead screw.

[0032] like Figures 3-5 As shown, the fixing assembly includes a first snap-fit ​​portion 221 located on the tray 21, a second snap-fit ​​portion 222 located on the rod 10 that matches the first snap-fit ​​portion 221, and a fixing member 223 for fixing the first snap-fit ​​portion 221 and the second snap-fit ​​portion 222. For example, the first snap-fit ​​portion 221 is designed with two types: a hinged socket and a hinged insert plate, and the diameter of the first snap-fit ​​portion 221 is designed with two types: 38mm and 48mm, to adapt to the usage requirements of the B-type (i.e., 48-type) and Z-type (i.e., 60-type) disc buckle frames. Figure 4 (a) is a square steel bar type hinged socket, Figure 4 (b) A round steel rod type hinged socket, Figure 4 (c) is the hinged insert plate one; correspondingly, the snap-fit ​​part two 222 is provided with a hinged insert plate two that matches the hinged socket one. Figure 5 (b) and the second hinged socket that mates with the first hinged socket. Figure 5 (a) The fastener 223 is a pin. When the first locking part 221 is rotated and adjusted as needed to make the tray 21 tilt to a certain angle, the pin is passed through the first locking part 221 and the second locking part 222 to complete the detachable connection between the rod 10 and the tray 21.

[0033] A 1-2mm gap is left between the first latching part 221 and the second latching part 222 to allow the first latching part 221 to rotate concentrically relative to the second latching part 222. When the first latching part 221 rotates concentrically relative to the second latching part 222, the tray 21 also rotates concentrically with the first latching part 221.

[0034] For example, the gear plate 23 is in the shape of a disc gear, and a through hole is provided in the middle of the gear plate 23 to facilitate the installation and inspection of the fixing part 223. There are two gear plates 23, which are symmetrically distributed on both sides of the first snap-fit ​​part 221. Correspondingly, there are two fixing plates 31, so that the gear plates 23 and the fixing plates 31 mesh and are fixed to form two fulcrums. With the fulcrums formed by the first snap-fit ​​part 221 and the second snap-fit ​​part 222, the entire disc buckle frame forms a statically indeterminate structure after the supporting part 40 supports and limits the fixing plate 31. The radial bearing and force transmission characteristics of the disc can redistribute the stress of the inclined plane and transmit it to the fixing plate 31, eliminating the overturning caused by the torque generated under the component force of the inclined plane pressure. At the same time, since the bottom of the tray 21 is not provided with longitudinal stiffening strips, the two gear plates 23 can make up for the problem of insufficient lateral stiffness of the tray 21 after the removal of the longitudinal stiffening strips.

[0035] The gear plate 23 adopts the form of a spur gear. Considering the static state, rough working environment, and control accuracy, the relevant parameters are set as follows: module 1.0~1.2, tooth tip width 1.0~1.5mm, tooth root width 2.0~2.5mm, and total tooth height and width 2.0~2.5mm.

[0036] In actual construction, since the rotation of the pallet 21 requires a certain amount of space, and the gear plate 23 needs to rotate in the same circle as the snap-fit ​​part 221, the diameter of the gear plate 23 can be designed according to the needs to avoid the diameter of the gear plate 23 being too large, so as to meet the rotation requirements of the pallet 21 and the requirement of the gear plate 23 rotating in the same circle as the snap-fit ​​part 221.

[0037] For example, an angle measuring device 231 is provided on the side of the gear plate 23 away from the fixed component. Figure 4 The rotation angle can be easily and accurately controlled on-site using the angle measuring device 231.

[0038] For example, taking the rotation angle of the gear as 0° when the tray 21 is horizontal, when the maximum rotation angle of the gear plate 23 is greater than 45°, the angle between the line connecting the high end 312 to the center of the arc-shaped portion 311 and the vertically upward direction is 55-60°. Taking the rotation angle of the gear plate as 0° when the tray 21 is horizontal, when the maximum rotation angle of the gear plate 23 is greater than 45°, the angle between the line connecting the low end 313 to the center of the arc-shaped portion 311 and the vertically downward direction is 75-80°.

[0039] Meanwhile, the height of the lower end 313 should be set to prevent the pallet 21 from colliding with the lower end 313 and the support part 40 when the pallet 21 is rotated to a greater than 45°.

[0040] In this example, the tray 21 is designed to rotate at an angle of 0-60°. For example... Figure 6 As shown, the angle α between the line connecting the center of the high end 312 to the center of the arc part 311 and the horizontal plane is 30°. When the tray 21 rotates to 60°, a better embedded structure is formed between the gear plate 23 and the fixed plate 31. Figure 8 The diagram shows the rotation angle of tray 21, where, Figure 8 (a) The middle tray 21 is in a horizontal position. Figure 8 (b) The rotation angle of tray 21 is 15°. Figure 8 (c) The rotation angle of tray 21 is 30°. Figure 8 (d) The rotation angle of tray 21 is 45°. Figure 8 (e) The rotation angle of tray 21 is 60°.

[0041] For example, the vertical projection of the center of the arc-shaped portion 311 coincides with the center of the gear plate 23.

[0042] like Figure 6 As shown in this example, the bottom of the fixing plate 31 is also connected to a foot plate 33, and three gusset plates 32 are provided. The three gusset plates 32 are respectively provided on the upper and lower parts of the side of the fixing plate 31 corresponding to the high end 312 and the lower part of the side of the fixing plate 31 corresponding to the low end 313.

[0043] For example, such as Figure 7 As shown, the support part 40 includes a support tray 41 that passes through the middle of the rod 10 and a top fastener that is threaded to the rod 10. The top fastener is located below the support tray 41 and is engaged with the support tray 41.

[0044] The pallet 41 has limiting portions 411 on both sides. The width of the lower part of the inclined adjustment structure, which is formed by connecting several fixing plates 31, foot plates 33, and connecting plates 32, is adapted to the pallet 41 so that the connecting plates 32 on both sides of the lower part of the inclined adjustment structure abut against the limiting portions 411. In this example, the limiting portion 411 is a vertical plate; there is a certain gap between the connecting plates 32 on both sides of the lower part of the inclined adjustment structure and the corresponding limiting portion 411. During construction, the gap is filled so that the connecting plates 32 and the limiting portions 411 are in an abutting state.

[0045] In this example, a ring 42 is provided at the center of the bottom of the support tray 41, and a top fastener is a top fastener 43. A stepped vertical hole 431 is formed in the center of the top fastener 43, which runs vertically through the center. The upper diameter of the vertical hole 431 is larger than the lower diameter, so that a receiving surface 432 is formed in the vertical hole 431. The upper part of the vertical hole 431 matches the ring 42 to achieve a snap-fit. The lower part of the vertical hole 431 is provided with an internal thread that matches the rod 10. After the support tray 41 is adjusted to abut against the tilt adjustment structure, the top fastener 43 is used to snap-fit ​​the support tray 41 with the ring 42 and to connect and fix it to the rod 10 through the internal thread, thus completing the fixation of the support tray 41 and the rod 10. In addition, two symmetrical fastening parts 433 are formed on both sides of the top fastener 43 extending away from the center of the top fastener 43, so as to facilitate the subsequent connection between adjacent disc buckle frames by using the fastening parts 433 in conjunction with the tie rod 53.

[0046] For example, the gaps between the components of the present invention can be set according to the actual situation to ensure the rotation adjustment effect, and chamfering design can be carried out to avoid collisions between the components during the rotation adjustment of the tray 21.

[0047] This invention also provides a method for erecting a modular scaffolding system adaptable to various sloping spaces, comprising the following steps: S1. Adjust the angle of the tray 21 according to the slope angle, insert the first snap-fit ​​part 221 at the bottom of the tray 21 into the second snap-fit ​​part 222 of the rod 10, and fix the first snap-fit ​​part 221 and the second snap-fit ​​part 222 through the fastener 223, so that the tray 21 is at a certain angle relative to the rod 10 for subsequent support on the inclined plane. Two fixing plates 31 are respectively installed on the foot plate 33, and the two fixing plates 31 are connected by three connecting plates 32 to form an inclined adjustment structure. The inclined adjustment structure is passed through the rod 10 and moved upward in a way that is offset from the gear plate 23 until the arc plate of the fixing plate 31 corresponds to the gear plate 23. The meshing connection between the arc part 311 of the fixing plate 31 and the gear plate 23 is completed by horizontal advancement. S2. Insert the support plate 41 onto the rod 10 and move it upward until it abuts against the bottom of the tilt adjustment structure. The gusset plates 32 on both sides of the lower part of the tilt adjustment structure abut against the limiting parts 411 on both sides of the support plate 41. Then, install the top fixing nut 43 on the rod 10 and rotate it upward until the upper part of the vertical hole 431 engages with the ring 42 and the bearing surface 432 in the top fixing nut 43 abuts against the ring 42. This completes the fixing of the support plate 41 and the rod 10, and the support plate 41 is used to support and limit the gear plate 23.

[0048] Then, the pole 10 is installed on the steel pipe pole 51. Figure 9 For example, the pole 10 is fixed to the steel pipe pole 51 by the screw nut 54 on the steel pipe pole 51. Subsequently, a tie rod 53 can be used to connect one end to the fastening part 433 of the top fixing nut 43 and the other end to the wheel 52 of the adjacent steel pipe pole 51. Figure 10 This addresses the safety hazard of the bowl-hinged connection between the screw nut 54 and the steel pipe pole 51 under inclined load, which is prone to displacement, and further strengthens the overall stability of the structure.

[0049] This invention deconstructs the existing rigid vertical fixing structure of the disc-lock frame tray 21 and the rod 10, and uses a hinged connection to allow the tray 21 to be adjusted to the required inclination slope according to the working conditions. Then, through the meshing and locking of the gear plate 23 and the fixing plate 31, and the support and limiting of the support tray 41, the disc-lock frame forms a statically indeterminate rigid structure, enabling the disc-lock frame to operate safely and conveniently in various sloping space conditions. It can be applied in the fields of construction and manufacturing, including the construction of inclined components in civil engineering and the construction of processing and assembly platforms for equipment manufacturing.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
