Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a scaffolding for construction projects that is easy to assemble. Background Technology

[0002] Construction engineering refers to the physical engineering project formed by the construction of various buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. During the construction process, whether it is the erection of the main structure of the building or the exterior wall decoration and pipeline installation, construction workers need to reach different heights and positions to operate. Scaffolding, as a temporary support structure, is usually composed of components such as uprights, horizontal bars, and diagonal bars, and is constructed through certain connection methods. It can provide construction workers with a stable and safe working platform, facilitating their high-altitude construction operations, material transportation, and safety protection.

[0003] The existing type of scaffolding for construction projects that is easy to assemble has the following shortcomings:

[0004] Traditional scaffolding often uses bolts, nuts, and clips for connection. During assembly, construction workers need to frequently use tools to tighten bolts or repeatedly adjust clips. This not only makes the process cumbersome and time-consuming, but also results in low overall assembly efficiency because multiple components need to be fixed sequentially. Furthermore, in traditional connection methods, the fixing of components relies on single-point force. For example, bolts are prone to loosening due to vibration or external pulling, and clips are prone to elastic fatigue failure after long-term load-bearing, leading to a decrease in the stability of the scaffolding structure and posing safety hazards. In addition, most traditional scaffolding structures are fixed, making it difficult to quickly adjust the connection positions of components and the overall structure, and failing to flexibly adapt to the diverse needs of different construction scenarios for the size and height of the work platform. Utility Model Content

[0005] This utility model proposes a construction scaffold that is easy to assemble, with the advantages of rapid assembly, stable connection, and flexible adjustment, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a scaffold for construction projects that is easy to assemble, comprising four vertical steel pipes, wherein a connecting component is slidably inserted into the top of the inner surface of each vertical steel pipe, and a horizontal support rod is slidably inserted into the opposite face of each of two adjacent connecting components, wherein a bearing plate is overlapped at the top of each horizontal support rod, wherein connecting holes are provided on both the upper and lower sides of the outer surface of each vertical steel pipe, and fixing slots are provided on both the left and right sides of the outer surface of each horizontal support rod.

[0007] The connecting assembly includes a connecting post. Four insertion holes are arranged in a circular array on the outer surface of the connecting post. One end of the horizontal support rod is slidably inserted into the inner surface of the insertion holes. Insertion posts are fixedly connected to both the upper and lower sides of the connecting post. The insertion posts are slidably inserted into the inner surface of the vertical steel pipe. A through-hole is formed in the middle of the insertion post, with the front and rear ends of the through-hole aligned with the front and rear sides of the connecting insertion hole, respectively. A positioning post is slidably inserted into the inner surface of the through-hole and the connecting insertion hole. A connecting groove is formed on the inner surface of the through-hole near the connecting post. A hemispherical block is slidably connected to the inner surface of the connecting groove. The side of the hemispherical block away from the connecting post extends to the middle of the through-hole. A clamping spring is fixedly connected to the middle of the side of the hemispherical block near the connecting post. Four right-angled inserts are fixedly arranged in a circular array on the side of the hemispherical block near the connecting post. The end of each right-angled insert, away from the hemispherical block, extends into the interior of the insertion hole, and its outer surface is slidably connected to the inner surface of the fixing groove.

[0008] Preferably, the positioning post includes a sliding insert post, which is slidably inserted into the inner surface of the communicating hole and the connecting hole, and a limit baffle is fixedly connected to the rear end of the sliding insert post.

[0009] Preferably, a knob is rotatably connected to the front center of the sliding insert, and a transmission screw is fixedly connected to the rear side of the knob.

[0010] Preferably, the sliding insert has a sliding groove that extends from left to right on its inner front side, and the rear end of the transmission screw extends into the sliding groove and has a threaded sliding plate threaded to its outer surface.

[0011] Preferably, the outer surface of the threaded slide plate is slidably connected to the inner surface of the sliding groove, and sliding plates are slidably sleeved on both the left and right sides of the threaded slide plate, with the two sliding plates slidably connected to the left and right sides of the sliding groove respectively.

[0012] Preferably, a pull plate is movably connected to the front side of the sliding plate, and the front end of the pull plate is movably connected to the front side of the inner wall of the sliding groove.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] 1. In this utility model, through the cooperation between the vertical steel pipe, connecting components, horizontal support rods, and positioning columns, during assembly, it is only necessary to put the vertical steel pipe over the plug-in column, insert the horizontal support rod into the plug-in hole, and then pass the positioning column through the connecting plug-in hole and the connecting hole to simultaneously fix the vertical steel pipe, plug-in column, and horizontal support rod. This eliminates the need for multiple operations with additional tools, greatly simplifies the assembly process, and significantly improves assembly efficiency. At the same time, after the hemispherical block is squeezed by the positioning column, the right-angle insert plate is inserted into the fixing slot, which, together with the limiting of the positioning column, forms a multi-point stable connection. Compared with the traditional single-point force-bearing connection method, this effectively enhances the stability and reliability of the overall scaffold structure.

[0015] 2. In this utility model, through the coordinated action of the knob on the positioning column, the transmission screw, the threaded sliding plate, and the sliding plate, after the positioning column is inserted, rotating the knob can cause the transmission screw to drive the threaded sliding plate to slide. The sliding plate is then pulled to lock the front side of the vertical steel pipe, and cooperates with the rear limiting baffle to achieve bidirectional locking of the positioning column, further preventing the positioning column from loosening and slipping out, and ensuring the durability of the scaffold connection. In addition, the modular design of each component of the scaffold allows for flexible addition or reduction of the number of vertical steel pipes and horizontal support rods, adjustment of the position of connecting components, and rapid change of the size and height of the scaffold to adapt to the diverse operational needs of different construction scenarios.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution: it includes four vertical steel pipes 1, with a connecting component 2 slidably inserted into the top of the inner surface of each vertical steel pipe 1. A horizontal support rod 3 is slidably inserted into the opposite surfaces of two adjacent connecting components 2. A bearing plate 4 overlaps the top of the horizontal support rod 3. Connecting insertion holes 11 are formed on both the upper and lower sides of the outer surface of the vertical steel pipe 1, and fixing grooves 31 are formed on both the left and right sides of the outer surface of the horizontal support rod 3. The connecting component 2 includes a connecting post 21, with four insertion holes 22 arranged in a circular array on the outer surface of the connecting post 21. One end of the horizontal support rod 3 is slidably inserted into the inner surface of the insertion hole 22. Insertion posts 23 are fixedly connected to both the upper and lower sides of the connecting post 21, and the insertion posts 23 are slidably inserted into the inner surface of the vertical steel pipe 1. A through hole 24 is provided in the middle, and the front and rear ends of the through hole 24 are aligned with the front and rear sides of the connecting hole 11, respectively. A positioning post 25 is slidably inserted into the inner surface of the through hole 24 and the connecting hole 11. A connecting groove 26 is provided on the inner surface of the through hole 24 near the connecting post 21. A hemispherical block 27 is slidably connected to the inner surface of the connecting groove 26. The side of the hemispherical block 27 away from the connecting post 21 extends to the middle of the through hole 24. A clamping spring 28 is fixedly connected to the middle of the side of the hemispherical block 27 near the connecting post 21. Four right-angled insert plates 29 are fixedly connected in a ring array on the side of the hemispherical block 27 near the connecting post 21. The end of the right-angled insert plate 29 away from the hemispherical block 27 extends into the interior of the insertion hole 22 and its outer surface is slidably connected to the inner surface of the fixing slot 31.

[0024] The overall effect of Embodiment 1 is as follows: During scaffold assembly, the vertical steel pipe 1 is aligned with the insertion column 23, and it is fitted onto the outer surface of the insertion column 23, completing the initial positioning of the vertical steel pipe 1 and the connecting component 2; then, the horizontal support rod 3 is inserted into the insertion hole 22, so that the horizontal support rod 3 is initially connected to the connecting column 21. At this time, the positioning column 25 is inserted from the connecting insertion hole 11 on the rear side of the vertical steel pipe 1. During the process of the positioning column 25 passing through the connecting hole 24, its front end will press against the hemispherical block 27. Under the pressure, the hemispherical block 27 overcomes the elastic force of the tightening spring 28 and moves towards the connecting component 21. The sliding mechanism 26 moves the right-angle insert plate 29, causing it to engage with the fixing slot 31, thus fixing the horizontal support rod 3 laterally. Simultaneously, the positioning column 25 penetrates the vertical steel pipe 1 and the insertion column 23, restricting the vertical movement of the connecting component 2 within the vertical steel pipe 1. This allows for the simultaneous and complete connection of the vertical steel pipe 1 with the insertion column 23 and the horizontal support rod 3, eliminating the need for multiple operations with additional tools and significantly improving the assembly efficiency of the scaffold. Furthermore, the multiple fixations of the right-angle insert plate 29 with the fixing slot 31 and the positioning column 25 enhance the stability of the overall structure.

[0025] Example 2: As Figure 4 As shown, this utility model provides a technical solution: the positioning post 25 includes a sliding insert post 251, which is slidably inserted into the inner surface of the connecting hole 24 and the connecting insertion hole 11. The rear end of the sliding insert post 251 is fixedly connected to a limit baffle 252. A knob 253 is rotatably connected to the middle of the front side of the sliding insert post 251. A transmission screw 254 is fixedly connected to the rear side of the knob 253. A sliding groove that runs through the left and right sides is opened on the front side of the interior of the sliding insert post 251. The rear end of the transmission screw 254 passes through the interior of the sliding groove and a threaded sliding plate 255 is threadedly connected to the outer surface of the sliding plate 255. The outer surface of the threaded sliding plate 255 is slidably connected to the inner surface of the sliding groove. Sliding locking plates 256 are slidably sleeved on both the left and right sides of the threaded sliding plate 255. The two sliding locking plates 256 are slidably connected to the left and right sides of the sliding groove, respectively. A pulling plate 257 is movably connected to the front side of the sliding locking plate 256. The front end of the pulling plate 257 is movably connected to the front side of the inner wall of the sliding groove.

[0026] The overall effect achieved in Embodiment 2 is as follows: When the positioning pin 25 is inserted into the connecting hole 24 and the connecting insertion hole 11, the limiting baffle 252 is stuck on the rear side of the vertical steel pipe 1, which plays a preliminary limiting role on the positioning pin 25. At this time, the knob 253 is rotated, and the knob 253 drives the transmission screw 254 to rotate. Since the transmission screw 254 is threadedly connected to the threaded sliding plate 255, the threaded sliding plate 255 slides in the sliding groove along the axial direction of the transmission screw 254. When the threaded sliding plate 255 slides, it pulls the plate 25 7. The sliding plate 256 is moved, so that the sliding plate 256 extends out of the sliding groove and locks the front surface of the vertical steel pipe 1. The limiting baffle 252 and the sliding plate 256 lock the positioning column 25 from the front and rear sides of the vertical steel pipe 1 respectively, forming a two-way limiting structure. This effectively prevents the positioning column 25 from sliding out of the connecting hole 11 and the connecting hole 24 due to vibration, external force and other factors during use, further improving the stability and reliability of the scaffold connection and ensuring the durability of the scaffold connection.

[0027] The working principle of the entire device is as follows: When erecting scaffolding, firstly, the plug-in column 23 of the connecting component 2 is inserted into the vertical steel pipe 1 to complete the initial assembly of the vertical steel pipe 1 and the connecting component 2. Then, the horizontal support rod 3 is inserted into the plug-in hole 22 of the connecting column 21 to connect the horizontal support rod 3 to the connecting component 2. Next, the positioning column 25 is inserted from the connecting plug-in hole 11 on the rear side of the vertical steel pipe 1. During the process of the positioning column 25 passing through the connecting hole 24, the linkage structure of the hemispherical block 27 and the right-angle insert plate 29 is triggered to fix the horizontal support rod 3. At the same time, the positioning column 25 passes through the vertical steel pipe 1 and the plug-in column 23 to complete the vertical connection and fixation. After inserting the positioning column 25, the knob 253 is rotated to activate the transmission screw 254, the threaded slide plate 255, and the sliding clip. The transmission structure of plate 256 allows the sliding plate 256 to lock the front side of the vertical steel pipe 1, and cooperates with the limiting baffle 252 on the rear side to firmly lock the positioning column 25 in the connecting socket 11 and the connecting hole 24. Finally, the bearing plate 4 is laid on the top of the horizontal support rod 3 to complete the scaffolding construction and provide a stable working platform for construction workers. When it is necessary to dismantle the scaffolding, turn the knob 253 in the opposite direction to make the sliding plate 256 retract into the sliding groove, release the locking of the positioning column 25, and then pull out the positioning column 25. At this time, the hemispherical block 27 is reset under the action of the tightening spring 28, which drives the right angle insert plate 29 to exit from the fixed slot 31, so that the horizontal support rod 3, the connecting component 2 and the vertical steel pipe 1 can be easily dismantled, realizing the quick dismantling of the scaffolding, which is convenient for transfer and reuse.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
