Description

Technical Field

[0001] This utility model belongs to the field of scaffolding technology, and in particular relates to a scaffolding assembly structure. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. It is mainly used in building construction, bridge construction, stage construction, and other fields, enabling workers to perform tasks at different heights. Scaffolding is typically composed of steel pipes, couplers, and footboards, possessing a certain degree of stability and load-bearing capacity to support the weight of workers, tools, and building materials. It provides a safe and convenient working space for construction workers, facilitating tasks such as bricklaying, plastering, painting, and equipment installation. As the project progresses, scaffolding can be erected, adjusted, and dismantled as needed.

[0003] The detachable connection methods for scaffolding steel pipes are usually as follows: Coupler connection, which connects steel pipes together using couplers, such as right-angle couplers, swivel couplers, and butt couplers, which are used to connect vertical, intersecting, and parallel steel pipes at any angle, respectively. However, multiple couplers are usually required at the intersection of multiple steel pipes, the disassembly process is relatively laborious, and the steel pipes are prone to tilting when connected; Bolt connection, which connects steel pipes together using bolts, usually requires multiple bolts to be used together, but bolt connections are prone to loosening, and the disassembly process is relatively cumbersome. Utility Model Content

[0004] The purpose of this utility model is to provide a scaffolding assembly structure that solves the problems of complex disassembly of steel pipes and easy pipe tilting in existing scaffolding assembly structures by setting up connecting plates and snap-fit ​​parts.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a scaffolding assembly structure, including a connecting plate. The connecting plate is composed of several square plates, and steel pipes are inserted into the inside of the square plates. A snap-fit ​​hole is opened on one side of the square plate. Two symmetrical arc-shaped snap-fit ​​plates are fixed on the inner periphery of the snap-fit ​​hole. A snap-fit ​​component is rotatably engaged inside the snap-fit ​​hole.

[0007] The snap-fit ​​component includes two symmetrical semi-cylinders. Each of the two semi-cylinders has an inlet slot, a spiral groove, and a snap-fit ​​groove on its circumferential side. The inlet slot on the circumferential side of the semi-cylinder is connected to the spiral groove, and the spiral groove on one of the semi-cylinders is connected to the snap-fit ​​groove on the other semi-cylinder.

[0008] The present invention is further provided that a sliding hole is provided on one side of the square plate, and a locking element is slidably fitted inside the sliding hole.

[0009] The present invention is further configured such that the locking component includes two symmetrical locking pins, each of the two locking pins having a locking groove on its circumferential side, and each of the two locking pins having a threaded hole through one end, and a first internal hexagon bolt being threaded into the two threaded holes.

[0010] The present invention is further configured such that a semi-conical column is fixed at one end of each of the two semi-cylinders, and a semi-conical countersunk hole is provided on the circumferential side of each of the two semi-conical columns.

[0011] The present invention is further configured such that the two semi-conical cylindrical sides are slidably fitted with a fixing ring, one end of the fixing ring having a conical hole through it, and the inner side of the conical hole having two symmetrical semi-circular countersunk threaded holes, and the two semi-circular countersunk threaded holes are threaded with second hexagon socket bolts, and the two second hexagon socket bolts are respectively rotatably fitted with the two semi-circular countersunk holes.

[0012] The present invention is further configured such that the conical hole is slidably engaged with the two semi-conical columns, and each of the two semi-conical columns has a semi-circular hole at one end, and the two semi-circular holes are respectively engaged with the steel pipe.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model inserts a steel pipe between two semi-circular holes at one end of a clamping component and controls the inner walls of the two semi-circular holes to fit against the outer circumference of the steel pipe. This utilizes the friction of the two contact surfaces to prevent the steel pipe from detaching from the two semi-circular holes, thus connecting the steel pipe to the clamping component. This allows the steel pipe to be fixedly clamped to the connecting plate via the clamping component, and the steel pipe does not need to be separated from the clamping component when disassembling it, facilitating quick reassembly next time.

[0015] 2. This utility model inserts the snap-fit ​​component into the snap-fit ​​hole on the connecting plate, and with the snap-fit ​​component rotated, the arc-shaped snap-fit ​​plate on the inner circumferential side of the snap-fit ​​hole enters the spiral groove from the inlet on the circumferential side of one half of the cylinder, and slides through the spiral groove to the snap-fit ​​groove on the circumferential side of the other half of the cylinder. With the help of the locking component, the snap-fit ​​component is restricted from rotating, so that the snap-fit ​​component and the connecting plate are fixedly snapped together. In this way, the steel pipe is quickly fixedly snapped together with the connecting plate through the snap-fit ​​component, and the connecting plate prevents several steel pipes on the same plane from tilting.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1

[0030] Please see Figure 1-8 This utility model is a scaffolding assembly structure, including a connecting plate 1, which is composed of several square plates 101. A steel pipe 6 is inserted into the square plate 101. A snap-fit ​​hole 102 is opened on one side of the square plate 101. Two symmetrical arc-shaped snap-fit ​​plates 103 are fixed on the inner circumferential side of the snap-fit ​​hole 102. A snap-fit ​​component 2 is rotatably fitted inside the snap-fit ​​hole 102. The snap-fit ​​component 2 includes two symmetrical semi-cylinders 201. Both semi-cylinders 201 have inlet slots 202, spiral grooves 203, and snap-fit ​​slots 204 on their circumferential sides. The inlet slots 202 on the circumferential side of the semi-cylinders 201 are connected to the spiral grooves 203. The spiral grooves 203 on the circumferential side of one semi-cylinder 201 are connected to the snap-fit ​​slots 204 on the circumferential side of the other semi-cylinder 201.

[0031] Specifically, a sliding hole 104 is provided on one side of the square plate 101. A locking component 3 is slidably fitted inside the sliding hole 104. The locking component 3 includes two symmetrical locking pins 301. Locking grooves 302 are provided on the periphery of both locking pins 301. A threaded hole 303 is provided through one end of both locking pins 301. A first internal hexagon bolt 304 is threaded into both threaded holes 303.

[0032] The operation process of this embodiment is as follows: Taking the splicing structure of four steel pipes 6 located on the same plane as an example, after connecting the steel pipe 6 with the snap-fit ​​2, first insert the locking part 3 with the first internal hex bolt 304 not tightened into the sliding hole 104, align the groove 202 on the snap-fit ​​2 with the arc-shaped clamping plate 103 in a straight line, and insert the snap-fit ​​2 into the snap-fit ​​hole 102 until the arc-shaped clamping plate 103 passes through the groove 202 and enters the spiral groove 203. Then, while rotating the steel pipe 6, insert the snap-fit ​​2 fixed at one end of the steel pipe 6 toward the bottom of the snap-fit ​​hole 102, so that the arc-shaped clamping plate 103 is in the spiral groove 203. 3. Slide the arc-shaped clamping plate 103 from the spiral groove 203 on the circumferential side of one half-cylinder 201 to the clamping groove 204 on the circumferential side of the other half-cylinder 201, and the clamping member 2 fixed at one end of the steel pipe 6 can no longer be rotated. At this time, the first internal hex bolt 304 can be locked, so that the gap between the two locking pins 301 begins to decrease, and the inner wall of the locking groove 302 on the circumferential side of the two locking pins 301 fits tightly with the circumferential side of the two half-cylinders 201. The friction between the inner wall of the locking groove 302 and the circumferential side of the two half-cylinders 201 restricts the rotation of the clamping member 2, thereby fixing the clamping member 2 to the connecting plate 1.

[0033] When it is necessary to disassemble the steel pipe 6, first loosen the first internal hex bolt 304. The gap between the two locking pins 301 begins to increase, and the inner wall of the locking groove 302 on the circumferential side of the two locking pins 301 is no longer tightly fitted with the circumferential side of the two semi-cylinders 201. At this time, while rotating the clamp 2 fixed at one end of the steel pipe 6 in the opposite direction, pull the clamp 2 fixed at one end of the steel pipe 6 out of the clamping hole 102. This allows the arc-shaped clamp 103 to slide from the clamping groove 204 on the circumferential side of one semi-cylinder 201 to the spiral groove 203 on the circumferential side of the other semi-cylinder 201, and then slide out from the inlet 202. The clamp 2 fixed at one end of the steel pipe 6 can then be completely pulled out of the clamping hole 102. If it is necessary to move the steel pipe 6 to other areas for assembly, it is not necessary to separate the steel pipe 6 from the clamp 2. Specific Implementation Example 2

[0035] Please see Figure 1-8 Based on the specific embodiment one, specifically, a semi-conical column 205 is fixed to one end of each of the two semi-cylinders 201. A semi-conical countersunk hole 206 is opened on the circumferential side of each of the two semi-conical columns 205. A fixing ring 4 is slidably fitted on the circumferential side of the two semi-conical columns 205. A conical hole 401 is opened through one end of the fixing ring 4. Two symmetrical semi-conical countersunk threaded holes 402 are opened on the inner circumferential side of the conical hole 401. A second hexagon socket bolt 5 is threaded inside each of the two semi-conical countersunk holes 402. The two second hexagon socket bolts 5 are rotatably fitted with the two semi-conical countersunk holes 206 respectively. The conical hole 401 is slidably fitted with the two semi-conical columns 205. A semi-conical hole 207 is opened at one end of each of the two semi-conical columns 205. The two semi-conical holes 207 are respectively inserted into the steel pipe 6.

[0036] The operation process of this embodiment is as follows: When it is necessary to connect the steel pipe 6 to the snap fastener 2, firstly, the two semi-conical columns 205 are combined into a complete cone and inserted into the fixing ring 4, and the two semi-circular countersunk holes 206 are respectively aligned with the two semi-circular countersunk threaded holes 402. Then, the second hexagon socket bolt 5 is inserted into the hole formed by the semi-circular countersunk hole 206 and the semi-circular countersunk threaded hole 402. At this time, the second hexagon socket bolt 5 is not tightened, so that the steel pipe 6 can be inserted between the two semi-circular holes 207. Then, the two second hexagon socket bolts 5 are tightened, and the two semi-conical columns 205 slide towards one end of the conical hole 401, so that the inner wall of the two semi-circular holes 207 is tightly fitted with the outer peripheral side of the steel pipe 6. In this way, the friction of the two contact surfaces is used to restrict the steel pipe 6 from disengaging from the two semi-circular holes 207, thereby realizing the fixed connection between the steel pipe 6 and the snap fastener 2.
