Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a modular scaffolding component for building engineering. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. At the main nodes of the scaffolding (i.e., the connection points where the uprights, longitudinal horizontal bars, and transverse horizontal bars are tightly joined), a coupler is installed to ensure the stability of the main node. Couplers include right-angle couplers, swivel couplers, and butt couplers. All of the aforementioned couplers are installed by tightening bolts to connect the uprights, longitudinal horizontal bars, and transverse horizontal bars. When tightening bolts, a torque of 65 N / m is usually selected to avoid damage. Excessive tightening force should be avoided. However, frequent and long-term bolt disassembly and assembly operations can easily cause deformation and stripping of threads. Summary of the Invention

[0003] The purpose of this invention is to propose a modular scaffolding component for building engineering, which overcomes the problems of deformation and stripping caused by long-term and frequent disassembly and assembly operations due to the bolt tightening method of traditional fasteners, thus posing safety hazards.

[0010] The first rubber layer is located inside the first connecting groove and is movably connected to the baffle plate;

[0011] In this process, the disc is placed on the upright, and the first connecting groove is precisely engaged with the molded part. Gravity causes the molded part to come into contact with the baffle plate. The baffle plate moves upward in the first connecting groove, and the first rubber layer moves towards the center of the disc until it is tightly abutted against the outer wall of the upright. The support of the molded part and the friction between the first rubber layer and the outer wall of the upright make the disc stably fastened to the upright.

[0012] Preferably, there are two first connecting slots and two second connecting slots, which are circumferentially and equally spaced on the disk, so that the molded part can pass through the second connecting slot but cannot pass through the first connecting slot.

[0013] Preferably, the disc has a limiting groove, which is connected to the first connecting groove. The limiting groove has a "convex" cross-section. A limiting block is slidably connected inside the limiting groove. The limiting block has a "convex" cross-section. The limiting block is fixedly connected to the baffle plate, so that the baffle plate is slidably connected to the first connecting groove.

[0014] Preferably, the disc has a horizontal groove, which is connected to the first connecting groove. A horizontal block is slidably connected in the horizontal groove, and a first sliding plate is connected to the horizontal block. The first sliding plate is located inside the first connecting groove and is slidably connected to the first connecting groove. A first rubber layer is bonded to the side of the first sliding plate facing the center of the disc. Both the first sliding plate and the stop plate are provided with mounting seats, and a linkage plate is rotatably connected between the two mounting seats.

[0015] Preferably, two first buckles are fixedly connected to the disc. The first buckle has a first buckle groove at its center and a first rectangular groove. A first rectangular block is slidably connected in the first rectangular groove. A second rubber layer is provided on the side of the first rectangular block facing the first buckle groove. The first rectangular block is fixedly connected to the baffle plate.

[0016] Preferably, three first clamping grooves are also provided on the first buckle, and a first clamping block is slidably connected in the first clamping groove. A second rubber layer is also provided on the side of the first clamping block facing the first buckle groove. A first ring groove is provided on the first buckle, and the first ring groove is located outside the first buckle groove. A first wire is provided in the first ring groove, and both ends of the first wire are connected to the first rectangular block. The three clamping blocks are connected to the first wire.

[0017] Preferably, the bottom of one of the first buckles is raised so that the lowest point of the first buckle groove of the first buckle is higher than the highest point of the first buckle groove of the other first buckle, and the length of the first rectangular groove and the first rectangular block are increased accordingly.

[0018] Preferably, a bracket is fixedly connected between the two horizontal blocks, the bracket is slidably connected to the horizontal groove, the bracket is fixedly connected to one of the mounting seats, the first sliding plate is fixedly connected to the rotating shaft, the rotating shaft is rotatably connected to the horizontal block, the horizontal block has a receiving groove, a torsion spring is provided in the receiving groove, the torsion spring is sleeved on the outer wall of the rotating shaft, the two ends of the torsion spring are respectively connected to the horizontal block and the rotating shaft, the horizontal block also has an arc-shaped groove, and a stop block is fixedly connected to the outer wall of the rotating shaft, the stop block is located inside the arc-shaped groove.

[0019] Preferably, the first sliding plate is fixedly connected to the extension block, the baffle plate has a through groove, and the extension block extends out of the first connecting groove through the through groove.

[0020] A method for dismantling and assembling main nodes of scaffolding includes the following steps:

[0021] For the main nodes of scaffolding erection, first determine the horizontal and vertical horizontal bars, put the two horizontal bars into the first and second fastening slots, and determine the fastening positions of the two horizontal bars with the first and second fastening slots;

[0022] The upright is set vertically. Multiple discs containing horizontal and vertical bars are sequentially placed on the upright. The first connecting groove on the disc is placed on the forming part of the upright, so that the forming part is located inside the first connecting groove, thus limiting the position of the disc on the upright.

[0023] Under the gravity of the components, horizontal and vertical bars, the baffle plate and the molded part come into close contact, and an upward force is applied to the baffle plate. Through the transmission of force, the first rubber layer has a force that comes into contact with the upright. The first rubber layer is in close contact with the outer wall of the upright, thus achieving the fastening of the upright.

[0024] Through the transmission of force, the second rubber layer has a force that abuts against the horizontal and vertical bars. The second rubber layer is in close contact with the horizontal and vertical bars respectively, thus achieving the fastening of the horizontal and vertical bars.

[0025] Disassemble the main nodes of the scaffolding, pull the extension block so that the first sliding plate and the pivot rotate around the virtual central axis of the pivot, causing the first rubber layer to detach from the close contact with the upright. Continue to pull the extension block so that the first sliding plate slides in the groove and the stop plate moves down in the first connecting groove. This cancels the contact between the first rubber layer and the upright, and the second rubber layer and the horizontal and vertical bars, making it easier for the upright, horizontal and vertical bars to detach from the components.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] This invention uses the support of molded parts and the friction between the first rubber layer and the outer wall of the pole to make the structure stably fastened to the pole. It does not use the traditional method of tightening bolts to fasten the pole, thus avoiding deformation and stripping caused by long-term and frequent disassembly and assembly operations, thereby eliminating safety hazards.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] Reference Appendix Figure 1 -Appendix Figure 11 A modular scaffolding component for building construction, comprising:

[0042] Multiple sets of molding components 1 are arranged in groups and fixed at equal intervals on the outer wall of the upright, so that the outer edge of the upright contains multiple sets of protruding parts;

[0043] Disk 2, hollow structure, its inner ring is the same as the outer ring of the upright;

[0044] The first connecting groove 3 and the second connecting groove 4 pass through the upper and lower sides of the disc 2 and are adapted to the molded part 1.

[0045] The baffle plate 5 is slidably disposed inside the first connecting groove 3;

[0046] The first rubber layer 6 is located inside the first connecting groove 3 and is movably connected to the baffle plate 5;

[0047] In this process, the disc 2 is placed on the upright, and the first connecting groove 3 is precisely engaged with the molded part 1. Under the action of gravity, the molded part 1 and the baffle plate 5 come into contact with each other. The baffle plate 5 moves upward in the first connecting groove 3, and the first rubber layer 6 moves towards the center of the disc 2 until it is tightly abutted against the outer wall of the upright. With the support of the molded part 1 and the friction between the first rubber layer 6 and the outer wall of the upright, the disc 2 is stably fastened to the upright.

[0048] Through the above technical solution, the support of the molded part 1 and the friction between the first rubber layer 6 and the outer wall of the pole make the component stably fastened to the pole. The traditional bolt tightening method is not used to fasten the pole, avoiding deformation and stripping caused by long-term and frequent disassembly and assembly operations, thereby eliminating safety hazards.

[0049] Two first connecting grooves 3 and two second connecting grooves 4 are arranged equidistantly on the disc 2. The molded part 1 can pass through the second connecting groove 4 but cannot pass through the first connecting groove 3. The disc 2 is adjusted by rotating the disc 2 so that the disc 2 can be lowered to a suitable position on the pole.

[0050] The disc 2 has a limiting groove 7, which is connected to the first connecting groove 3. The limiting groove 7 has a "convex" cross-section. A limiting block 8 is slidably connected inside the limiting groove 7. The limiting block 8 has a "convex" cross-section. The limiting block 8 is fixedly connected to the baffle plate 5, so that the baffle plate 5 is slidably connected to the first connecting groove 3.

[0051] The disc 2 has a horizontal groove 9, which is connected to the first connecting groove 3. A horizontal block 10 is slidably connected in the horizontal groove 9. The horizontal block 10 is connected to a first sliding plate 11. The first sliding plate 11 is located inside the first connecting groove 3 and is slidably connected to the first connecting groove 3. A first rubber layer 6 is bonded to the side of the first sliding plate 11 facing the center of the disc 2. The first sliding plate 11 and the baffle 5 are both provided with mounting seats 12. A linkage plate 13 is rotatably connected between the two mounting seats 12. When the baffle 5 moves upward inside the first connecting groove 3, the first sliding plate 11 slides towards the center of the disc 2 through the transmission of the linkage plate 13.

[0052] Two first buckles 14 are fixedly connected to the disc 2. The first buckle 14 has a first buckle groove 15 at its center for buckling the horizontal bar and the vertical bar. The first buckle 14 has a first rectangular groove 16. A first rectangular block 17 is slidably connected in the first rectangular groove 16. A second rubber layer 18 is provided on the side of the first rectangular block 17 facing the first buckle groove 15. The first rectangular block 17 is fixedly connected to the baffle plate 5.

[0053] Three first clamping grooves 19 are also provided on the first buckle 14. First clamping blocks 20 are slidably connected in the first clamping grooves 19. The first clamping blocks 20 are also provided with a second rubber layer 18 on the side facing the first buckle groove 15. A first ring groove 21 is provided on the first buckle 14. The first ring groove 21 is located outside the first buckle groove 15. A first wire 22 is provided in the first ring groove 21. Both ends of the first wire 22 are connected to the first rectangular block 17. The three clamping blocks are connected to the first wire 22. When the first rectangular block 17 moves upward in the first rectangular groove 16, the first wire 22 will shrink in the first ring groove 21, causing the three clamping blocks to move towards the center of the first buckle groove 15, and cooperate with the first rectangular block 17 to fix the horizontal bar located in the first buckle groove 15.

[0054] The bottom of one of the first buckles 14 is raised so that the lowest point of the first buckle groove 15 of the first buckle 14 is higher than the highest point of the first buckle groove 15 of the other first buckle 14, and the length of the first rectangular groove 16 and the first rectangular block 17 is increased accordingly.

[0055] A bracket 23 is fixedly connected between two horizontal blocks 10. The bracket 23 is slidably connected to the horizontal groove 9. The bracket 23 is fixedly connected to one of the mounting seats 12. The first sliding plate 11 is fixedly connected to the rotating shaft 24. The rotating shaft 24 is rotatably connected to the horizontal block 10. The horizontal block 10 has a receiving groove 25. A torsion spring 26 is installed in the receiving groove 25. The torsion spring 26 is sleeved on the outer wall of the rotating shaft 24. The two ends of the torsion spring 26 are respectively connected to the horizontal block 10 and the rotating shaft 24. The horizontal block 10 also has an arc-shaped groove 27. A stop block 28 is fixedly connected to the outer wall of the rotating shaft 24. The stop block 28 is located inside the arc-shaped groove 27.

[0056] The first sliding plate 11 is fixedly connected to the extension block 29, and the baffle plate 5 has a through groove 30. The extension block 29 extends out of the first connecting groove 3 through the through groove 30.

[0057] Working principle:

[0058] For the main nodes of scaffolding erection, first determine the horizontal and vertical horizontal bars, put the two horizontal bars into the first and second fastening slots, and determine the fastening positions of the two horizontal bars with the first and second fastening slots.

[0059] The upright is set vertically. Multiple discs 2 containing horizontal and vertical bars are sequentially placed on the upright. The first connecting groove 3 on the disc 2 is placed on the forming part 1 of the upright, so that the forming part 1 is located inside the first connecting groove 3, thus limiting the position of the disc 2 on the upright.

[0060] Under the gravity of the components, horizontal and vertical bars, the baffle 5 and the molded part 1 are in close contact, and an upward force is applied to the baffle 5. Through the transmission of force, the first rubber layer 6 has a force that abuts against the upright. The first rubber layer 6 is in close contact with the outer wall of the upright, thus realizing the fastening of the upright.

[0061] Through the transmission of force, the second rubber layer 18 has a force that abuts against the horizontal and vertical bars. The second rubber layer 18 abuts tightly against the horizontal and vertical bars respectively, thereby achieving the fastening of the horizontal and vertical bars.

[0062] Disassemble the main nodes of the scaffolding, pull the extension block 29 so that the first sliding plate 11 and the pivot 24 both rotate around the virtual central axis of the pivot 24, so that the first rubber layer 6 is partially separated from the close contact with the upright. Continue to pull the extension block 29 so that the first sliding plate 11 slides in the groove and the baffle 5 moves down in the first connecting groove 3, thereby canceling the contact between the first rubber layer 6 and the upright, and the second rubber layer 18 and the horizontal and vertical bars, making it easier for the upright, horizontal and vertical bars to detach from the components.

[0063] It is important to note that:

[0064] The first rubber layer 6 and the second rubber layer 18 are elastic and resilient. When the component is not assembled, the inner ring of the first rubber layer 6 coincides with the inner ring of the disc 2, and the inner ring of the second rubber layer 18 coincides with the inner ring of the first buckle 14. The first sliding plate 11 moves towards the upright, and the first rectangular block 17 and the first clamping block 20 move towards the first buckle groove 15. This will cause the first rubber layer 6 and the second rubber layer 18 to be squeezed, which will increase the friction between the first rubber layer 6, the second rubber layer 18 and the upright, the horizontal bar, and the vertical bar.

[0065] Reference Appendix Figure 6The black dots are the connection points of the first wire 22 with the first rectangular block 17 and the first clamping block 20. When the first rectangular block 17 moves upward in the first rectangular groove 16, a pulling force is applied to the first wire 22, and the first wire 22 located in the first annular groove 21 contracts, so that the remaining three first clamping blocks 20 also apply force in the direction of the first buckle groove 15.

[0066] Reference Appendix Figure 8 The connection between the pivot 24 and the first slide plate 11 is located at the center of the side of the first slide plate 11. Under the transmission of the linkage plate 13, the pushing force applied to the first slide plate 11 causes the first slide plate 11 to squeeze the first rubber layer 6 without causing the first slide plate 11 to rotate. Only when the extension block 29 is pulled can the first slide plate 11 rotate.

[0067] The concept of this invention is as follows:

[0068] The existing main nodes are constructed using fasteners, which mainly fix the uprights, horizontal bars, and longitudinal bars by tightening bolts. Frequent and long-term bolt removal and installation operations can easily cause fastener deformation and bolt stripping. To avoid the aforementioned problems, a method of constructing the main nodes without using bolt tightening is adopted.

[0069] Unlike the horizontal and longitudinal bars, the uprights are arranged in groups at equal intervals on the outer wall of the uprights, resulting in multiple sets of protruding parts on the outer edge of the uprights. Each group consists of two molded parts 1, which are arranged at 90° to each other. The discs 2 contain two first connecting grooves 3 and two second connecting grooves 4, allowing multiple discs 2 to stand on the uprights at different heights of the molded parts 1. The weight of the horizontal and longitudinal bars and the weight of the components themselves are used to press on the molded parts 1, so that the baffle 5 is subjected to force. This causes the first rubber layer 6 and the second rubber layer 18 to be tightly fixed to the uprights and the horizontal and longitudinal bars, respectively. The heavier the weight, the more stable the fixation. This allows the main nodes to be erected without using bolts to tighten them, avoiding problems such as bolt stripping and fastener deformation.

[0070] During disassembly, the components need to be lifted to detach them from the molded part 1. However, due to prolonged use after the scaffolding is erected, the weight of the scaffolding causes the first rubber layer 6 to be in close contact with the uprights, and the second rubber layer 18 to be in close contact with the horizontal and vertical bars. Lifting requires a huge force, and it is very easy for the first rubber layer 6 to rub against the uprights, resulting in severe wear of the first rubber layer 6. Therefore, a pullable extension block 29 is used. When pulled, the first sliding plate 11 rotates around the virtual central axis of the pivot 24, so that the contact area between the first rubber layer 6 and the outer wall of the uprights is gradually reduced, which facilitates the overall lifting of the components and thus enables the disassembly of the scaffolding.

[0071] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
