Description

Technical Field

[0001] This invention belongs to the field of building technology, and in particular relates to a connecting fastener structure for steel pipe scaffolding and its connection method. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. It is classified into external scaffolding and internal scaffolding according to its location; and into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding according to its materials. At the intersections of steel pipe scaffolding, a connecting fastener structure is required for installation. However, existing connecting fastener structures generally use bolts for splicing and fixing, increasing the difficulty and time of the splicing process, reducing efficiency, and generally lacking a compression structure. This means that the connecting fastener structure is installed solely with bolts, increasing the internal stress of the connection structure, which is detrimental to the long-term use of the equipment and reduces its effectiveness. Furthermore, it generally lacks an adjustment structure; when the steel pipe needs to be tilted and fixed, steel wire or other structures are required for binding, which can easily loosen the binding and reduce its effectiveness. Summary of the Invention

[0012] One end of the first spring is fixed to the inner wall of the other side of the pressing plate, and the other end of the first spring is fixed to the outer wall of the second connecting plate.

[0013] Furthermore, the extrusion assembly includes a first rotating plate, a rotating shaft, a second spring, a rotating frame, an extrusion plate, a lead screw, and a rotating handle;

[0014] The rotating frame is installed on the outside of the first rotating plate. The first rotating plate is symmetrically welded on one side of the outer wall of the connecting fastener body. One end of the rotating shaft is rotatably connected to the top and bottom of the first rotating plate, and the other end is fixed to the inner wall of the rotating frame.

[0015] The second spring is sleeved on the rotating shaft;

[0016] The extrusion plate is located on the outside of the connecting fastener body. The extrusion plate is rotatably connected to the lead screw, and the outer end of the lead screw is fixedly connected to the rotating handle.

[0017] Furthermore, the extrusion plate is arc-shaped, conforming to the semi-circular ring of the connecting fastener body.

[0018] Furthermore, the second spring is a torsion spring.

[0019] Furthermore, the rotation adjustment assembly includes a rotating column, a second rotating plate, a threaded rod, a rotating wheel, and an internal gear groove;

[0020] Multiple threaded grooves are opened on the adjusting seat; one end of the rotating column is fixedly connected to the steel pipe clamp, and the other end is rotatably connected in the threaded groove;

[0021] The second rotating plate is located outside the adjusting seat, and rotating wheels are symmetrically installed on the outside of the second rotating plate. A threaded rod is installed on the rotating wheel and the threaded rod is threadedly connected to the inside of the second rotating plate.

[0022] An internal gear groove is pre-made on the inner wall of the rotating wheel, and a toothed belt is meshed on the inner wall of the internal gear groove.

[0023] Furthermore, the steel pipe clamp is composed of a first steel pipe clamp plate and a second steel pipe clamp plate spliced ​​together, and the second steel pipe clamp plate is bolted to the first steel pipe clamp plate.

[0024] Furthermore, the threaded grooves are arranged in a circular pattern.

[0025] Furthermore, the inner wall of the connecting fastener body is provided with slots.

[0026] The present invention also discloses a connection method for the connecting fastener structure of the steel pipe scaffolding, comprising the following steps:

[0027] S1. Place the main body of the connecting fastener over the vertical steel pipe. First, squeeze the two semi-circular rings on one side through the extrusion component, causing the two semi-circular rings to rotate and merge and align.

The splicing assembly and the pressing assembly are respectively disposed on both sides of the connecting fastener body. The adjusting seat is disposed on one outer wall of the connecting fastener body and is fixed to the rotating adjusting assembly. A steel pipe clamp for fixing horizontal steel pipes is externally connected to the rotating adjusting assembly. This invention employs a splicing device, which can limit the equipment through a limiting splicing structure, thereby simplifying the splicing process, shortening the splicing time, and improving the splicing efficiency. The pressing device can compress the equipment, reducing the internal stress of the connecting structure through external pressure, thereby ensuring long-term use of the equipment and improving the effectiveness of the device. The rotating adjusting device allows for fixing of steel pipes when tilting is required, preventing loosening of the steel pipes and improving the binding effect.

[0033] Furthermore, the rotating adjustment component is designed to clamp the steel pipe and rotate it. The threaded grooves are arranged in a circular pattern. Different distributions of the threaded grooves can fix the steel pipe in different positions, thus allowing the steel pipe to be fixed in a horizontal or inclined state. The rotating adjustment component can limit and fix the inclined steel pipe, further shortening the construction time. Attached Figure Description

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figure 1 As shown, this invention discloses a connecting fastener structure for steel pipe scaffolding, including a connecting fastener body 1, which is composed of two semi-circular rings spliced ​​together. A splicing component 2 is fixed on one side of the spliced ​​semi-circular rings, and a pressing component 3 is fixed on the other side. An adjusting seat 4 is welded to the outer wall of one of the semi-circular rings, and a rotating adjusting component 5 is fixed to the outer wall of the adjusting seat 4. The connecting fastener body 1 is used to fix vertical steel pipes, and a steel pipe clamp for fixing horizontal steel pipes is fixed to the outside of the rotating adjusting component 5. When the steel pipe clamp needs to be tilted, the rotating adjusting component 5 can drive the steel pipe clamp to rotate. The inner wall of the connecting fastener body 1 is provided with slots 6, which can engage the steel pipes and improve the fixing effect of the steel pipes.

[0043] like Figure 1 , Figure 3 and Figure 4As shown, the splicing assembly 2 includes a first connecting plate 201, a splicing plate 202, a second connecting plate 203, a splicing groove 204, a pressing plate 205, a first spring 206, and a limiting rod 207. The first connecting plate 201 is connected to the outside of a semicircular ring of the connecting fastener body 1, and the first connecting plate 201 is fixedly connected to the splicing plate 202. The second connecting plate 203 is connected to the outside of another semicircular ring, and a splicing groove 204 is opened on the inner wall of the second connecting plate 203 corresponding to the splicing plate 202. The pressing plate 205 is an L-shaped plate, and multiple limiting rods 207 are provided on one inner wall of the pressing plate 205. During splicing, the limiting rods 207 are sequentially inserted into the second connecting plate 203 and the splicing plate 202. The first spring 206 is fixed on the other inner wall of the pressing plate 205, and the other end of the first spring 206 is fixed on the outer wall of the second connecting plate 203.

[0044] Working principle: Before the main body 1 of the connecting fastener is aligned, the pressing plate 205 is pulled, thereby moving the limiting rod 207 into the interior of the second connecting plate 203. Then, the splicing plate 202 on the first connecting plate 201 is engaged with the splicing groove 204 in the second connecting plate 203. Then, the pressing plate 205 is released. At this time, under the action of the first spring 206, the limiting rod 207 is inserted into the interior of the splicing plate 202, thereby limiting the splicing plate 202 and splicing and fixing the main body 1 of the connecting fastener. The equipment can be restricted by the limiting splicing structure, thereby simplifying the splicing process, shortening the splicing time, and improving the splicing efficiency.

[0045] See Figure 1 and Figure 4 The extrusion assembly 3 includes a first rotating plate 301, a rotating shaft 302, a second spring 303, a rotating frame 304, an extrusion plate 305, a lead screw 306, and a rotating handle 307. The rotating frame 304 is installed on the outside of the first rotating plate 301. The first rotating plate 301 is symmetrically welded to one side of the outer wall of the fastener body 1. One end of the rotating shaft 302 is rotatably connected to the top and bottom of the first rotating plate 301, and the other end is fixed to the inner wall of the rotating frame 304. The second spring 303 is sleeved on the rotating shaft 302. The extrusion plate 305 is provided with... On the outside of the connecting fastener body 1, the pressing plate 305 is rotatably connected to the lead screw 306, and the outer end of the lead screw 306 is fixedly connected to the rotating handle 307; the second spring 303 is a torsion spring. When the pressing plate 305 is reset, the first rotating plate 301 is reset along the rotating shaft 302 under the torsion action of the second spring 303; the pressing plate 305 is arc-shaped and follows the shape of the semi-circular ring of the connecting fastener body 1. The pressing plate 305 can perform secondary pressing on the connecting fastener body 1, thereby reducing the load on the limiting rod 207.

[0046] First, insert the steel pipe into the middle of the connecting fastener body 1 and engage the protrusion of the steel pipe with the slot 6. Then, turn the rotating handle 307 to rotate the screw 306 along the pressing plate 305. Under the action of the threaded hole, the pressing plate 305 presses against the connecting fastener body 1, causing the first rotating plate 301 on the connecting fastener body 1 to rotate along the rotating shaft 302 on the rotating frame 304, thereby aligning the two parts and clamping and fixing the steel pipe. When the steel pipe needs to be disassembled, turn the rotating handle 307 in the opposite direction. Under the action of the screw 306, the pressing plate 305 is reset. Then, under the torsion of the second spring 303, the first rotating plate 301 on the connecting fastener body 1 is reset along the rotating shaft 302. This pressing action reduces the internal stress of the connecting structure through external pressure, ensuring long-term use of the equipment and improving the effectiveness of the device.

[0047] See Figure 1 , Figure 2 , Figure 4 and Figure 5 The rotation adjustment assembly 5 includes a rotating column 501, a second rotating plate 502, a threaded groove 503, a threaded rod 504, a rotating wheel 505, an internal gear groove 506, and a toothed belt 507. Multiple threaded grooves 503 are formed on the adjustment seat 4. One end of the rotating column 501 is fixedly connected to a steel pipe clamp, and the other end is rotatably connected to the threaded groove 503. The second rotating plate 502 is disposed outside the adjustment seat 4, and rotating wheels 505 are symmetrically installed on the outside of the second rotating plate 502. A threaded rod 504 is installed on the rotating wheel 505, and the other end is threadedly connected to the second rotating plate 502. An internal gear groove is pre-formed on the inner wall of the rotating wheel 505. 506, a toothed belt 507 is meshed on the inner wall of the internal gear groove 506; the steel pipe clamp is spliced ​​from the first steel pipe clamp plate 7 and the second steel pipe clamp plate 8, the second steel pipe clamp plate 8 is bolted to the first steel pipe clamp plate 7, the first steel pipe clamp plate 7 and the second steel pipe clamp plate 8 are aligned, and then connected by screws and other structures, thereby locking the first steel pipe clamp plate 7 and the second steel pipe clamp plate 8; the threaded grooves 503 are arranged in a circle, and the different distribution of the threaded grooves 503 can fix the first steel pipe clamp plate 7 and the second steel pipe clamp plate 8 in different positions, so that the steel pipe can be fixed in a horizontal or inclined state.

[0048] When other steel pipes need to be tilted and fixed, the rotating column 501 on the second steel pipe clamp 8 is rotated along the adjusting seat 4, thereby aligning the second rotating plate 502 with the tilted threaded groove 503. Then, the threaded rod 504 is tightened with a wrench, and then, under the action of the threaded hole, the threaded rod 504 is screwed into the threaded groove 503. Then, under the action of the internal gear groove 506 and the toothed belt 507, another threaded rod 504 is also screwed into the threaded groove 503, thereby fixing the second steel pipe clamp 8. Then, the steel pipe is placed into the second steel pipe clamp 8. Finally, the first steel pipe clamp 7 and the second steel pipe clamp 8 are aligned, and then connected by screws or other structures, thereby locking the first steel pipe clamp 7 and the second steel pipe clamp 8. When the steel pipe needs to be tilted and fixed, it can be fixed by adjusting the clamping structure to avoid the steel pipe from loosening and improve the binding effect.

[0049] See Figures 1-5 A method for connecting a steel pipe scaffolding fastener structure includes the following steps:

[0050] S1. Place the main body 1 of the connecting fastener on the outside of the vertical steel pipe. First, squeeze the two semi-circular rings on one side through the extrusion component 3, and drive the two semi-circular rings to rotate so that the two semi-circular rings merge and align.

[0051] S2. The connecting fastener body 1 is spliced ​​and fixed on the other side by splicing component 2;

[0052] S3. Open the steel pipe clamp and insert the horizontal steel pipe into the steel pipe clamp. After fixing the steel pipe clamp, adjust the rotating adjustment component 5 according to the required tilt angle. The rotating adjustment component 5 drives the steel pipe clamp to rotate relative to the adjustment seat 4, so that the horizontal steel pipe and the vertical steel pipe are tilted and fixed.

[0053] 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.
