[0002] In the field of construction, scaffolding is an indispensable auxiliary structure, and its design and use efficiency directly affect the project progress and construction safety. Traditional scaffolding mainly adopts a separate bolt connection method, that is, the various components of the scaffolding are connected by independent bolts and nuts. Although this connection method can achieve structural stability, it has obvious disadvantages in actual operation. When building or dismantling scaffolding, construction workers must prepare and manage a large number of bolts and nuts. They are also required to carefully collect each bolt after the operation to prevent loss. This process is not only time-consuming and labor-intensive, but also very likely to cause the loss or mismatch of these small components. The lack of bolts will directly affect the re-assembly and use of the scaffolding, adding additional costs and safety hazards, and thus affecting the assembly efficiency and structural stability of the scaffolding. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the utility model provides a scaffold for construction projects that is easy to disassemble and assemble, and solves the problem that the various components of the traditional scaffold are connected by independent bolts and nuts.

DETAILED DESCRIPTION

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-4As shown, the utility model provides a technical solution: a scaffold for construction projects that is easy to disassemble and assemble, including a support frame 1, the number of support frames 1 is two groups, and a plurality of connecting members 2 are connected to the outer surface of the support frame 1. Through the cooperation between the connecting members 2 and the support frame 1, the support frame 1 is connected to the support rod 3 through the connecting members 2, which avoids the need to prepare a large number of connecting components during installation and the collection of connecting components during disassembly. The installation and disassembly are convenient, and the adaptability and flexibility of the scaffold are enhanced. The connecting member 2 includes a connecting block 201, and two first U-shaped frames 202 are fixedly connected to both sides of the connecting block 201. The directions of the two first U-shaped frames 202 are opposite, and one end of the first U-shaped frame 202 is rotatably connected to a rotating shaft 203. The outer wall of the rotating shaft 203 is rotatably connected to a connecting shaft 204. The first U-shaped frame 202 is rotatably connected to the second U-shaped frame 205 through the connecting shaft 204 and the rotating shaft 203. The other end of the U-shaped frame 202 is fixedly connected to two fixing blocks 206, and a rotating rod 207 is rotatably connected between the two fixing blocks 206. The outer wall of the rotating rod 207 is fixedly connected to a connecting screw 208, and the end of the connecting screw 208 away from the rotating rod 207 is fixedly connected to a baffle 209. Due to the provision of the baffle 209, when the outer wall of the connecting screw 208 rotates and squeezes the first U-shaped frame 202, the baffle 209 can effectively limit the connecting nut 210, thereby preventing the connecting nut 210 from rotating too much and disengaging from the connecting screw 208, thereby reducing the risk of losing the connecting nut 210. The connecting screw 208 is externally threadedly connected to the connecting nut 210, and the first U-shaped frame 202 and the second U-shaped frame 205 are respectively provided with two empty slots 211 at one end away from the connecting shaft 204. The two empty slots 211 are opposite to each other, and the connecting screw 208 passes through the empty slot 211;

[0020] The support frame 1 is fixedly connected to the support rod 3 through the connecting piece 2. The support rod 3 runs through the first U-shaped frame 202 and the second U-shaped frame 205. The support rod 3 is cross-distributed. The number of support rods 3 is several. A support plate 4 is provided between the corresponding two support rods 3. Two groups of hooks 5 are symmetrically fixed on both sides of the support rod 3. The support plate 4 is hung on the outer wall of the support rod 3 through the hook 5. The outer wall of the support frame 1 is fixedly connected with several limit plates 6. The corresponding two limit plates 6 are located on both sides of several first U-shaped frames 202 and second U-shaped frames 205. Because the limit plates 6 are symmetrically arranged on both sides of the first U-shaped frame 202 and the second U-shaped frame 205, the limit plates 6 can prevent the support frame 1 from passing through the connection When the part 2 is connected to the support rod 3, the connecting part 2 slides on the outer wall of the support frame 1, limiting the range of the connecting part 2 and ensuring the stability of the connecting part 2 during use. The outer wall of the support frame 1 is fixedly connected to two brackets 7. Because the brackets 7 are provided, the cross distribution of the brackets 7 provides additional support for the support frame 1 when in use, ensuring the structural strength of the support frame 1 when in use, making the support frame 1 more stable when in use. The two brackets 7 are cross-designed, and a number of universal wheels 8 are fixedly connected to the bottom of the support frame 1. Because the universal wheels 8 are provided, the universal wheels 8 facilitate the movement of the scaffolding at the construction site, improve construction efficiency, reduce manpower burden, and ensure that the scaffolding can be easily moved to any construction position.

[0021] The working principle of the present invention is as follows: when using the scaffold, the first U-shaped frame 202 and the second U-shaped frame 205 are connected to the outer wall of the support frame 1 and the support rod 3 through the cooperation of the rotating shaft 203 and the connecting shaft 204, and the connecting screw 208 is rotated between the two corresponding fixed blocks 206 to the empty slot 211 at one end of the first U-shaped frame 202 and the second U-shaped frame 205 through the rotating rod 207, and then the connecting nut 210 is rotated. Since the connecting nut 210 is threadedly connected to the connecting screw 208, the connecting nut 210 rotates on the outer wall of the connecting screw 208, and the connecting screw 208 is continuously squeezed during the rotation process. Press the second U-shaped frame 205 so that the second U-shaped frame 205 is squeezed and fitted onto one side of the first U-shaped frame 202, connect the support frame 1 and the support rod 3, and then hang the support plate 4 on the corresponding two support rods 3 through the hook 5, and use the scaffold. When disassembling, rotate the connecting nut 210 so that the connecting nut 210 releases the squeezing of the second U-shaped frame 205, and then rotate the connecting screw 208 to disengage the connecting screw 208 from the empty slots 211 at the ends of the first U-shaped frame 202 and the second U-shaped frame 205, remove the connector 2, separate the support frame 1 and the support rod 3, and store them.
