Description

Technical Field

[0001] This invention belongs to the field of scaffolding technology, specifically relating to a segmented tie rod for a flower basket cantilever scaffold. Background Technology

[0002] Cantilevered scaffolding utilizes outward-extending cantilever structures along the building's edges to support the external scaffolding, transferring all or part of the scaffolding's load to the building structure. Due to its relatively low cost, wide applicability, and lack of limitations imposed by floor height and site, it has seen rapid development in high-rise and super high-rise buildings. The flower basket cantilever scaffolding is one common type of scaffolding.

[0003] However, in practice, traditional basket-style scaffolding tie rods must avoid the vertical and horizontal bars on the same I-beam, meaning the tie rods cannot be installed in a straight line and can only be installed at an angle, resulting in poor structural stability. Furthermore, traditional basket-style tie rods are generally three-sectioned; if applied to high-rise buildings, the long tie rods are inconvenient to transport and lead to low installation and dismantling efficiency. These problems not only affect the construction progress but may also pose safety hazards. Summary of the Invention

[0004] To address the aforementioned issues, this invention discloses a segmented tie rod for a flower basket cantilever frame. The segmented design makes installation and transportation more convenient, significantly improving structural stability and load-bearing capacity, while also protecting the building structure and increasing construction efficiency.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A segmented tie rod for a flower basket cantilever frame includes an upper connecting plate, a lower connecting plate, a set of upper connecting parts, and at least one set of lower connecting parts. The upper connecting plate, upper connecting parts, lower connecting parts, and lower connecting plate are connected from top to bottom by round steel rods. The round steel rods are welded and fixed to the upper and lower connecting plates, and are movably connected to the upper and lower connecting parts by threads. The outer ends of the upper and lower connecting plates are provided with connecting holes. The upper and lower connecting parts have the same structure. The upper connecting part includes an upper support plate, a lower support plate, and two screw rods. The upper and lower support plates are provided with three round holes, of which the middle round hole is connected to the round steel rod by a nut, and the two screw rods are connected to the other two round holes by nuts. The length of the upper and lower support plates of the upper connecting part is greater than the length of the upper and lower support plates of the lower connecting part. All the round steel rods are in a straight line.

[0006] As an improvement of the present invention, the upper connecting plate is bent in the middle.

[0007] As an improvement of the present invention, the round steel rod is a straight rod.

[0008] As an improvement of the present invention, the diameter of the circular hole is larger than the outer diameter of the thread of the round steel rod and the screw.

[0009] As an improvement of the present invention, the round steel rod is fully welded and fixed at the contact points with the upper connecting plate and the upper connecting member.

[0010] How to use a segmented tie rod for a flower basket cantilever frame: Connect the lower connecting plate to the center of the I-beam on the ground. Connect the lower connecting piece, upper connecting piece, and upper connecting plate upwards using round steel rods. The number of lower connecting pieces is determined according to the height requirements. Disassemble the lower connecting piece and the upper connecting piece, pass them through the scaffolding, and then reassemble them. Install them vertically or diagonally as needed. When installing the upper connecting plate, align the center point with the center position of the pre-embedded part of the lower I-beam. Finally, adjust all the round steel rods to a straight line and fix them in place.

[0011] The beneficial effects of this invention are as follows: 1. Compared with traditional flower basket handles, the segmented handles described in this invention are easier to install and transport.

[0012] 2. Improve construction quality: The use of turnbuckles makes it easier to fine-tune the length of the tie rod, adapting to structural deformation and construction errors.

[0013] 3. Improve construction efficiency: When the upper bolts are pre-embedded, only the center point needs to be aligned with the center position of the lower I-beam pre-embedded. There is no need to consider the tilt angle of the tie rod, which improves the accuracy and efficiency of on-site construction.

[0014] 4. Safe and reliable: Avoids conflict between the tie rod and the horizontal or vertical poles of the frame, thus preventing the tie rod from being unable to be installed or from being too close to the vertical pole, which would cause the tie rod to transmit lateral horizontal force to the frame and ensure the stability of the frame.

[0015] 5. Reduced project costs: The segmented tie rod construction method described in this invention can reduce material waste, allow for repeated use, reduce construction waste, and is environmentally friendly, thereby reducing project costs. Attached Figure Description

[0021] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0022] like Figure 1 As shown, the present invention provides a segmented tie rod for a flower basket cantilever frame, comprising an upper connecting plate 1, a lower connecting plate 2, a set of upper connecting parts 3, and at least one set of lower connecting parts 4. The upper connecting plate 1, upper connecting parts 3, lower connecting parts 4, and lower connecting plate are connected from top to bottom by a round steel rod 5. The round steel rod 5 is welded and fixed to the upper connecting plate 1 and the lower connecting plate 2. The round steel rod 5 is movably connected to the upper connecting parts 3 and the lower connecting parts 4 by threads. The outer ends of the upper connecting plate 1 and the lower connecting plate 2 are provided with connecting holes 6. The upper connecting parts 3 and the lower connecting parts 4 have the same structure.

[0023] The segmented tie rod of the flower basket cantilever scaffold described in this invention differs from the traditional flower basket scaffold tie rod in that the upper connecting piece 3 and the lower connecting piece 4 of this device can be disassembled and passed through the scaffold, and then reassembled, avoiding conflict between the tie rod and the horizontal or vertical poles of the scaffold. It can be installed vertically or diagonally as needed. It is only necessary to align the center point with the center position of the pre-embedded I-beam at the bottom, and finally adjust all the round steel rods to a straight line and fix them.

[0024] In addition, this device has one set of upper connectors 3 and at least one set of lower connectors 4. The number of lower connectors can be determined according to the height requirements, allowing for flexibility.

[0025] The upper connector 3 only needs to pass through the inner upright of the scaffold, so only one set is needed. Because the upright of the disc-lock scaffold has a connecting disc with a size of approximately 130mm, the influence of the connecting disc needs to be considered when the upper connector 3 passes through the upright. Therefore, the upper connector 3 is larger than the lower connector 4. The length of the upper connector 3 is 160-200mm, and the length of the lower connector 4 is approximately 140-200mm.

[0026] The upper connecting member 3 of the present invention includes an upper support plate 7, a lower support plate 8 and two screws 9. The upper support plate 7 and the lower support plate 8 are provided with three round holes 11, wherein the middle round hole is connected to the round steel rod 5 by a nut, and the two screws 9 are connected to the other two round holes by nuts 10. The length of the upper support plate and the lower support plate of the upper connecting member 3 is greater than the length of the upper support plate and the lower support plate of the lower connecting member 4.

[0027] The upper connecting plate 1 of the present invention is bent in the middle to facilitate installation.

[0028] The round steel rod 5 described in this invention is a straight rod. After installation, it is ensured that all the round steel rods 5 are in a straight line to facilitate load transfer.

[0029] The circular hole described in this invention is not a screw hole. The diameter of the circular hole 11 is larger than the outer diameter of the threads of the round steel rod 5 and the screw 9. For example, the diameter of the circular hole is 22 and the outer diameter of the thread of the screw is 20, allowing for adjustment of direction.

[0030] The round steel rod 5 and the screw rod 9 are inserted into the round hole and connected by the nut 10, which can realize the fine adjustment of the rod length to adapt to structural deformation and construction errors.

[0031] The round steel rod 5 of the present invention is fully welded and fixed at the contact points with the upper connecting plate 1 and the upper connecting piece 2 to ensure that the strength meets the standard.

[0032] It should be noted that the above content merely illustrates the technical concept of the present invention and should not be construed as limiting the scope of protection of the present invention. For those skilled in the art, various improvements and modifications can be made without departing from the principle of the present invention, and all such improvements and modifications fall within the scope of protection of the claims of the present invention.
