Description

Technical Field

[0001] This invention relates to the field of steel structure roof construction technology, specifically to the installation components and construction methods for large-span cantilevered irregular-shaped components of complex steel structure roofs. Background Technology

[0002] In large buildings such as cultural centers and stadiums, cantilever structures are often used to achieve an aesthetically pleasing overall appearance. Furthermore, due to the diverse external structures, the steel roof structures are often complex, large-span, and irregularly shaped. In these cantilever structures, the main component, the cantilever beam, is not positioned at the conventional vertical angle when installed on the connecting beam. This makes determining the connection position between the cantilever beam and the connecting beam, as well as adjusting the horizontal and vertical angles at the connection point, extremely difficult during construction. Therefore, we have designed an installation component and construction method for large-span irregularly shaped cantilever beams.

[0003] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0004] The purpose of this invention is to provide an installation assembly and construction method for large-span cantilever irregularly shaped components of complex steel structure roofs, in order to solve the problem mentioned in the background art that when the main component, the cantilever beam, is installed on the connecting beam in a large-span and irregularly shaped cantilever structure, its position is not determined by the conventional vertical angle. Thus, during construction, it is often very difficult to determine the connection position between the cantilever beam and the connecting beam, as well as to adjust the horizontal and vertical angles at the connection.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an installation assembly for large-span cantilever irregularly shaped components of complex steel structure roofs, comprising multiple sets of support columns, connecting beams erected on the support columns, and cantilever beams installed on the connecting beams, and further comprising: A mobile positioning unit, installed on the connecting beam, is used to initially locate the installation position of the cantilever beam; The adjustment unit, located on the moving positioning unit, is used to precisely position the lifted cantilever beam and adjust its horizontal state and installation angle before connecting it to the connecting beam.

[0006] Preferably, the mobile positioning unit includes: A movable frame is mounted on a connecting beam, and clamping rollers are provided at each of the four corners of the movable frame. Four sets of connecting plates, one end of which is rotatably mounted on the clamping roller, and the other end extends to the middle of the movable frame and is provided with a synchronous elastic clamping member, which is used to provide clamping force for the clamping roller so that the clamping roller is clamped on the connecting beams of different widths. The clamping roller is provided with a self-locking structure. The positioning column is installed on the connecting beam and located at the center of the supporting column; The positioning component, installed on the movable frame, is used in conjunction with the positioning column to determine the moving distance of the movable frame.

[0007] Preferably, the synchronous elastic clamping member includes: Four sets of gear shafts are located at the end of the connecting plate away from the clamping rollers and rotate at a fixed point on the moving frame; Four sets of clamping gears are fixedly mounted on the gear shaft, and the four sets of clamping gears are meshed with each other. A rotating plate is fixed at one end to the upper end of any gear shaft, and a lever is fixed at the other end. The upper end of the lever passes through the movable frame to the outer end of the movable frame. A fixed plate is fixedly mounted on the movable frame, and an arc-shaped elastic telescopic rod is provided between the fixed plate and the lever.

[0008] Preferably, the positioning component includes a winding drum rotatably mounted on a movable frame. A reset torsion spring is provided on the rotating shaft of the winding drum. A connecting rope is wound on the winding drum, and a collar is provided at the end of the connecting rope away from the winding drum. The collar is fitted onto the positioning post.

[0009] Preferably, the adjustment unit includes: The clamping and positioning assembly, mounted on the movable frame, is used for the initial clamping and positioning of the lifted cantilever beam; An angle docking component, mounted on a movable frame, is used to move and adjust the clamping and positioning component to adjust the horizontal angle of the clamped cantilever beam and its docking position with the connecting beam.

[0010] Preferably, the angle docking component includes: A slide rail frame is fixedly mounted on a movable frame, and a slider is slidably mounted on the slide rail frame; A screw is threaded onto the slider to drive the slider to move on the slide rail. A moving motor is provided at one end of the screw and the moving motor is fixed on the slide rail frame. The rotating shaft has one end fixedly mounted on the clamping and positioning assembly, and the other end passes through the slider and is equipped with a rotating motor. The rotating motor is fixedly mounted on the slider and is used to drive the clamping and positioning assembly to rotate.

[0011] Preferably, the clamping and positioning component includes: The clamping frame is fixedly mounted on the end of the rotating shaft; Two sets of clamping arms are symmetrically arranged and slidably mounted on the clamping frame, and rotating disks are provided at the close ends of the two sets of clamping arms. The power unit, located on the clamping frame, is used to drive the two sets of clamping arms to move synchronously.

[0012] Preferably, the power component includes: Two sets of racks are obliquely and symmetrically fixed on the clamping arm; A rotating gear is positioned at the obliquely symmetrical center of two sets of racks and meshes with the two sets of racks to drive the two sets of racks to rotate. A clamping motor is connected to the rotating gear to drive the rotating gear to rotate.

[0013] A construction method for installing complex steel structure roof components with large spans and irregular shapes includes the following steps: S1: The position of the mobile positioning unit is determined; S11. The movable frame is installed on the connecting beam. By moving the lever, the clamping rollers are opened and the movable frame is placed on the connecting beam. Then, the clamping rollers are clamped on the connecting beam by the action of the arc-shaped elastic telescopic rod, so that the movable positioning unit can adapt to connecting beams of different widths. S12. Determine the position of the center point of the connecting beam at the connection point of the cantilever beam and the connecting beam, and calculate the distance D between this position and the positioning column. Then, put the collar on the positioning column, push the moving frame to move until the connecting rope is stretched to the length D, and then use the self-locking structure to self-lock the clamping roller. S2: Connection and adjustment of the adjustment unit and cantilever beam: S21. Connect to the cantilever beam and perform initial positioning. Move the slider by the moving motor to move the clamping and positioning assembly outward until the cantilever beam is located between the two clamping arms. Then, the clamping motor works to drive the two sets of clamping arms to move towards the cantilever beam, and the cantilever beam is clamped and fixed by the rotating disk to determine the vertical position of the cantilever beam. S22. Vertical angle adjustment: After the cantilever beam is rotated and clamped in step S, the cantilever beam is lifted up or down by the lifting equipment. At this time, the cantilever beam will rotate around the clamping rotation point mentioned above. Then, by installing a level on the clamping arm, observe whether the cantilever beam is in a horizontal state, and then determine whether the lifting equipment should continue to change the height. S23. Cantilever beam angle adjustment: The rotating motor starts working and drives the rotating shaft to rotate, thereby changing the angle of the clamping frame and adjusting the angle of the cantilever beam clamped by the clamping arm on the clamping frame. S24. The cantilever beam is connected by moving the motor to drive the slider to slide, so that the cantilever beam slowly moves to the connecting beam to achieve connection and then is fixed.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention, by setting a moving positioning unit on the connecting beam and using an adjustment unit, can quickly locate the position of the cantilever beam. Before the cantilever beam is connected and fixed to the connecting beam, it can effectively and accurately adjust the horizontal and vertical angles of the cantilever beam and achieve connection with the connecting beam, which greatly reduces the installation difficulty of cantilever beams in large-span irregular cantilever components and speeds up construction efficiency.

[0026] Implementation 2 The difference between this embodiment and Embodiment 1 is that this embodiment also provides a construction method for installing complex steel structure roof large-span cantilever irregularly shaped components, including the following steps: S1: The position of the mobile positioning unit 4 is determined; S11. The movable frame 41 is installed on the connecting beam 2. By moving the lever 444, the clamping roller 42 is opened, and the movable frame 41 is placed on the connecting beam 2.

The rotating disk 513 clamps and fixes the cantilever beam 3 so that the vertical position of the cantilever beam 3 is determined. S22. Vertical angle adjustment: After the cantilever beam 3 is rotated and clamped in step S21, the cantilever beam 3 is lifted up or down by the lifting equipment. At this time, the cantilever beam 3 will rotate around the clamping rotation point mentioned above. Then, by installing a level on the clamping arm 512, observe whether the cantilever beam 3 is in a horizontal state, and then determine whether the lifting equipment should continue to change the height. S23, the angle of the cantilever beam 3 is adjusted. The rotating motor 526 starts to work and drives the rotating shaft 525 to rotate, thereby changing the angle of the clamping frame 511, so as to adjust the angle of the cantilever beam 3 clamped by the clamping arm 512 on the clamping frame 511. S24. The connection of the cantilever beam 3 is achieved by the operation of the moving motor 524, which drives the slider 522 to slide, so that the cantilever beam 3 slowly moves to the connecting beam 2 to achieve connection and further fixation.
