Description

Technical Field

[0001] This invention relates to the field of construction machinery technology for super high-rise buildings, specifically a temporary tie rod point-supported climbing formwork attachment device for use when the structure is missing. Background Technology

[0002] In recent years, the development of super high-rise buildings has been rapid, and the design of super high-rise buildings has become increasingly diverse. In order to meet the needs of construction design, the structural design has become increasingly complex, which has brought many challenges to construction.

[0003] For example, many projects use a design that lacks the outer structure of the building, which can lead to a situation where the climbing scaffold lacks attachment during the construction of the main structure, making it difficult to lift.

[0004] Typical projects would use cantilevered scaffolding, which is then dismantled and reassembled to bridge floors with structural defects. However, this approach is complex, requires more time, and involves the erection of scaffolding at high altitudes and the dismantling of scaffolding, posing significant safety risks.

[0005] If there are only a few structural defects, some projects may choose to add temporary steel beams or concrete beams to enable the climbing formwork to be lifted. After the climbing formwork is lifted, the temporary steel beams or concrete beams will be removed. Although this solution can solve the problem of continuous lifting of the climbing formwork, the temporary beams are all large in size, making installation and dismantling difficult and costly.

[0006] Therefore, a solution that is low-cost, easy to operate, and can ensure continuous lifting of the climbing formwork even when the structure is missing, is needed to minimize the impact on the construction period. Summary of the Invention

[0007] The purpose of this invention is to provide a temporary tie rod point-supported climbing scaffold attachment device for use when the structure is missing, including a main structure, a climbing scaffold frame, connecting tie rods and several connecting devices.

[0008] The connecting device includes a connecting rod.

[0009] The connecting rods and tie rods are connected to form a truss system.

[0010] The connecting rod includes several rods I, II and III.

[0011] One end of the tie rod I is connected to the connecting rod, and the other end is connected to the main structure.

[0012] Tie rods II and III are horizontal tie rods.

[0013] Both ends of the pull rod II are connected to the connecting rods of the adjacent connecting devices.

[0014] One end of the tie rod III is connected to the connecting rod of the outermost connecting device, and the other end is connected to the main structure.

[0015] An attachment device is installed on the climbing frame.

[0016] The attachment device is connected to the connecting device, and the connection point is the attachment point of the climbing frame.

[0017] Furthermore, a variable damping adjustment rod is installed on the tie rod I.

[0018] During the lifting process of the climbing scaffold, the damping of the variable damping adjustment rod is adjusted according to the stress of the connecting rod.

[0019] Furthermore, the tie rod I is connected to the main structure via a tie rod anchor head.

[0020] Furthermore, the connecting device also includes a conversion plate and a connecting gripper, one end of which is connected to the connecting rod and the other end of which is connected to the conversion plate.

[0021] The other side of the conversion plate is connected to the attachment device.

[0022] A connecting rod is attached to the connecting rod.

[0023] Furthermore, the connecting gripper is a four-grip connecting gripper, comprising four gripper heads.

[0024] Furthermore, the conversion plate is a steel conversion plate.

[0025] Furthermore, the connecting gripper, conversion plate, and attachment device are connected by bolts.

[0026] Furthermore, the main structure is a main structure with missing structural layers.

[0027] Furthermore, after the climbing scaffold has been lifted past the structural gap, the connection between the attachment device and the connecting device is released, allowing the climbing scaffold to continue to be lifted upwards.

[0028] Furthermore, depending on the number of missing layers in the project structure, the tie-rod truss structure will be designed as a single-layer truss or a multi-layer truss structure to meet the lifting requirements of the climbing scaffold.

[0029] The technical effects of this invention are undeniable, and its beneficial effects are as follows:

[0030] (1) The present invention can realize the continuous lifting of the climbing scaffold when the structure is missing, avoiding the erection of cantilever scaffolding on high floors and also avoiding the dismantling and assembly of climbing scaffolding on high floors.

[0031] (2) The present invention has a simple structure, is easy to install and dismantle, and has little impact on the construction period of the main structure;

[0032] (3) The present invention is low in cost, uses little steel, and has low construction cost and risk. Attached Figure Description

[0037] Example 1:

[0038] See appendix Figure 1 , 2 A temporary tie rod point-supported climbing scaffold attachment device for use when the structure is missing includes a main structure 6, a climbing scaffold frame 10, connecting tie rods 1 and several connecting devices 2.

[0039] The connecting device 2 includes a connecting rod 8.

[0041] The connecting rod 1 includes several rods I 101, rod II 102 and rod III 103.

[0042] One end of the pull rod I101 is connected to the connecting rod 8, and the other end is connected to the main structure 6.

[0044] The two ends of the pull rod II102 are respectively connected to the connecting rods of the adjacent connecting devices.

[0045] One end of the pull rod Ⅲ103 is connected to the connecting rod 8 of the outermost connecting device, and the other end is connected to the main structure 6.

[0046] An attachment device 9 is provided on the climbing frame 10.

[0048] Example 2:

[0049] The main structure of this embodiment is the same as that of embodiment 1. Furthermore, a variable damping adjustment rod 5 is installed on the pull rod I101.

[0050] During the lifting process of the climbing frame 10, the damping of the variable damping adjustment rod 5 can be adjusted according to the stress of the connecting tie rod 1 to reduce the impact of vibration and load changes on the tie rod truss system during lifting.

[0051] Example 3:

[0052] The main structure of this embodiment is the same as any one of embodiments 1 to 2. Furthermore, the tie rod I101 is connected to the main structure 6 through the tie rod anchor head 4.

[0057] A connecting rod 1 is connected to the connecting rod 8.

[0058] Example 5:

[0059] The main structure of this embodiment is the same as that of embodiment 4. Furthermore, the connecting gripper 11 is a four-grip connecting gripper, which includes four gripper heads.

[0060] Example 6:

[0061] The main structure of this embodiment is the same as any one of embodiments 4 to 5. Furthermore, the conversion plate 3 is a steel conversion plate.

[0062] Example 7:

[0063] The main structure of this embodiment is the same as any one of embodiments 4 to 6. Furthermore, the connecting gripper 11, the conversion plate 3 and the attachment device 9 are connected by bolts.

[0064] Example 8:

[0065] The main structure of this embodiment is the same as any one of embodiments 1 to 7. Furthermore, the main structure 6 is the main structure 6 of the structural missing layer 7.

[0066] Example 9:

[0067] The main structure of this embodiment is the same as any one of embodiments 1 to 8. Further, after the climbing frame 10 is lifted past the structural missing layer 7, the connection between the attachment device 9 and the connecting device 2 is released, so that the climbing frame 10 can continue to be lifted upward.

[0068] Example 10:

[0069] The main structure of this embodiment is the same as any one of embodiments 1 to 9. Furthermore, depending on the number of missing layers in the project structure, the tie rod truss structure is designed as a single-layer truss or a multi-layer truss structure to meet the lifting requirements of the climbing scaffold 10.

[0070] Example 11:

[0071] The main structure of this embodiment is the same as any one of embodiments 1 to 10. Furthermore, a method for continuous lifting of the climbing scaffold is provided when a structural element is missing, using a temporary tie rod point-support attachment device. The device for implementing this method mainly includes a connecting tie rod 1, a connecting device 2, an attachment device 9, and a variable damping adjustment rod 5.

[0072] Furthermore, the connecting rod 1 is connected at one end to the main structure 6 and at the other end to the connecting device 2, forming a tie-rod truss structure through multiple connecting rods. The connecting devices in the truss structure can all serve as attachment points for the climbing scaffold. The tie-rod truss structure can be designed as a single-layer or multi-layer truss structure depending on the number of missing layers in the project structure, to meet the lifting requirements of the climbing scaffold.

[0073] Furthermore, the connecting device 2 consists of a connecting rod 8, a connecting grab 11, and a conversion plate 3. The connecting rod and the connecting tie rod form a stable truss system. The connecting grab serves as a connecting and conversion device between the truss and the attachment device. It is connected to the climbing frame attachment 9 through the conversion plate, providing a stable attachment point for the climbing frame 10 and enabling continuous lifting of the frame.

[0074] Furthermore, the connecting grab 11 is a 4-grab connecting grab, which includes 4 grab heads. This connecting device is relatively stable, and the conversion plate 3 is a 10mm thick steel conversion plate with 2 bolt holes corresponding to the connecting grab heads. The connecting grab, conversion plate and climbing frame attachment device can be connected and fastened by M30 bolts.

[0075] Furthermore, one end of the connecting rod 1 is connected and secured to the main structure 6 via the rod anchor head 4, and the other end is connected to the connecting rod 8. After the connecting rods are installed and the truss system is formed, the truss system can be tensioned and secured using the variable damping adjustment rod 5 on each connecting rod. After tensioning and securing, the climbing frame supports are installed, and the climbing frame can be lifted after the supports are installed.

[0076] Furthermore, the variable damping adjustment rod 5 can adjust the damping according to the stress of the tie rod during the climbing frame lifting process, so as to reduce the impact of vibration and load changes on the tie rod truss system during lifting, and play the role of vibration reduction and stress monitoring.

[0077] Furthermore, after the climbing scaffold has been lifted past the structurally missing layer 7, the bolts between the climbing scaffold attachment device 9 and the connecting grab 11 are loosened. After the tie rod truss separates from the climbing scaffold, the scaffold can continue to be lifted upwards. Then, the tie rods and connecting devices and other components can be removed in sequence.

[0079] The main structure of this embodiment is the same as any one of embodiments 1 to 11. Furthermore, this device uses a tie rod structure as the attachment point for the climbing scaffold, enabling continuous lifting of the climbing scaffold. The tie rod structure is simple, lightweight, and easy to install and dismantle. At the same time, with the help of tie rod stress monitoring equipment, the support load during the use and lifting process of the climbing scaffold can be monitored in real time, providing an early warning function.

[0081] The main structure of this embodiment is the same as any one of embodiments 1 to 12. Furthermore, this invention is planned to be applied to the construction of the main building of Phase III of Area B of Garden City International Resort Center.
