Description

Technical Field

[0001] The invention belongs to the technical field of scaffolding, and in particular relates to a segmented pull rod of a flower basket cantilever frame. Background Art

[0002] Cantilever scaffolding utilizes cantilevered structures extending outward from the edge of the building structure to support the exterior scaffolding, transferring all or part of the scaffolding load to the building structure. Due to its relatively low cost, wide applicability, and freedom from floor height and site restrictions, it is rapidly gaining popularity in high-rise and super-high-rise buildings. Flower basket cantilever scaffolding is a common type of scaffolding.

[0003] However, in actual operation, traditional flower basket scaffolding tie rods must avoid the vertical and horizontal rods on the same I-beam, resulting in the tie rods being unable to be pulled straight and can only be pulled at an angle, resulting in poor structural stability. Furthermore, traditional flower basket tie rods are generally three-section, which makes them long and inconvenient to transport when used in high-rise buildings, and leads to low installation and disassembly efficiency. These problems not only affect construction progress but also pose potential safety risks. Summary of the Invention

[0004] In order to solve the above problems, the present invention discloses a segmented pull rod for a flower basket cantilever frame. The segmented design makes installation easier and transportation more convenient. Not only is the structural stability and bearing capacity significantly improved, but it can also protect the building structure and improve construction efficiency.

[0005] To achieve the above object, the technical solution of the present invention is as follows: The lockhole engages with the lockhole to engage with the lockhole, and the lockhole engages with the lockhole to engage with the lockhole The lockhole engages with the lockhole engages with the lockhole engages with the lockhole engages with the lockhole engages with the lockhole engages with the lockhole engages with the lockhole engages with the lockhole engages with the lockhole engages with the lockhole engages

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

[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 or the screw.

[0009] As an improvement of the present invention, the contact points between the round steel rod, the upper connecting plate and the upper connecting piece are fully welded and fixed.

[0010] A method for using a segmented pull rod of a flower basket cantilever frame: Connect the lower connecting plate to the center of the I-beam on the ground, and connect the lower connecting piece, upper connecting piece, and upper connecting plate upwards through the round steel rod. The number of lower connecting pieces is determined according to the height requirements. Disassemble the lower connecting piece and the upper connecting piece, and then reinstall them after passing through the scaffolding. Install it vertically or diagonally as needed. When installing the upper connecting plate, align the center point with the embedded center position of the lower I-beam, and finally adjust all the round steel rods to a straight line and fix them.

[0011] The beneficial effects of the present invention are: 1. Compared with the traditional flower basket pull rod, the segmented pull rod of the present invention is easier to install and more convenient to transport.

[0012] 2. Improve construction quality: The use of basket bolts makes it easier to fine-tune the length of the pull rod and adapt to structural deformation and construction errors.

[0013] 3. Improve construction efficiency: Because when the upper bolts are embedded, it is only necessary to align the center point with the center position of the embedded lower I-beam, and there is no need to consider the inclination angle of the tie rod, which improves the construction accuracy and efficiency on site.

[0014] 4. Safe and reliable: Avoid conflicts between the pull rod and the horizontal rod or vertical rod of the frame, so as to avoid the pull rod being unable to be pulled or the pull rod being close to the vertical rod, causing the pull rod to transmit horizontal force to the frame, thereby ensuring the stability of the frame.

[0015] 5. Reduce project costs: The use of the segmented pull rod construction described in the present invention can reduce material waste, enable repeated turnover and use, reduce construction waste, be green and environmentally friendly, and thus reduce project costs.

[0021] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0022] like Figure 1 As shown, the segmented pull rod of a flower basket cantilever frame described in the present invention includes an upper connecting plate 1, a lower connecting plate 2, a group of upper connecting parts 3, and at least one group of lower connecting parts 4. The upper connecting plate 1, the upper connecting part 3, the lower connecting part 4, and the 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 part 3 and the lower connecting part 4 through a threaded connection. The outer ends of the upper connecting plate 1 and the lower connecting plate 2 are provided with connecting holes 6, and the upper connecting part 3 and the lower connecting part 4 have the same structure.

[0023] The biggest difference between the segmented pull rod of the flower basket cantilever frame described in the present invention and the traditional flower basket scaffolding pull rod is that the upper connecting member 3 and the lower connecting member 4 described in the present device can be disassembled and passed through the scaffolding, and then reinstalled to avoid conflict between the pull rod and the horizontal bar or vertical bar of the scaffolding. It can be installed vertically or obliquely as needed. It only needs to align the center point with the embedded center position of the lower I-beam, and finally adjust all the round steel rods to a straight line and fix them.

[0024] In addition, the device has a group of upper connecting parts 3 and at least one group of lower connecting parts 4. The number of lower connecting parts can be determined according to the height requirements, which is flexible and maneuverable.

[0025] The upper connector 3 only needs to pass through the inner vertical pole of the scaffolding, so only one set is needed. And because there is a connecting disc on the vertical pole of the buckle frame, the size is about 130mm. When the upper connector 3 passes through the vertical pole, the influence of the connecting disc needs to be considered. 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 about 140-200mm.

[0026] The upper connecting member 3 described in the present invention includes an upper support plate 7, a lower support plate 8 and two screw rods 9. Three circular holes 11 are provided on the upper support plate 7 and the lower support plate 8, wherein the middle circular hole is connected to the round steel rod 5 by a nut, and the two screw rods 9 are connected to the other two circular 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 for easy installation.

[0028] The round steel rods 5 of the present invention are straight rods. After installation, all the round steel rods 5 are ensured to be in a straight line to facilitate load transmission.

[0029] The circular hole in the present invention is not a screw hole. The diameter of the circular hole 11 is larger than the outer diameter of the thread 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, so there is room for adjusting the direction.

[0030] The round steel rod 5 and the screw rod 9 are inserted into the round hole and connected by the nut 10, so that the length of the pull rod can be fine-tuned to adapt to structural deformation and construction errors.

[0031] The contact points between the round steel rod 5 and the upper connecting plate 1 and the upper connecting piece 2 are fully welded and fixed to ensure that the strength meets the standards.

[0032] It should be noted that the above content merely illustrates the technical idea of the present invention and cannot be used to limit the scope of protection of the present invention. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications all fall within the scope of protection of the claims of the present invention.
