Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a large-scale hollow truss structure deformation multi-point dynamic dual-control combination device. Background Art

[0002] A hollow truss structure is a system of overlapping beams and columns, eliminating walls and significantly reducing deadweight while ensuring structural stability. Dynamic dual-control of deformation at multiple points: This cast-in-place concrete structure, due to its large span and heavy deadweight load, is prone to deformation before its overall shape is firmly established, posing a safety hazard. Therefore, temporary supports are installed at the base of the hollow truss, and sandboxes and dual jacks are positioned above the eight support columns. This allows the use of sandboxes and jacks to slowly separate the temporary supports from the superstructure once the overall truss structure is formed.

[0003] A sand box refers to a steel barrel device whose internal walls are filled with homogeneous sand. It is concave and convex and has sand unloading holes around it. After being fully compacted, it can stably support the upper structure. In the later stage, the amount of sand unloaded is used to control the downward displacement of the sand box to achieve displacement regulation of the upper structure. The existing sand box device automatically unloads sand through the force applied above the sand box. Since there are multiple sand and gravel unloading holes, uniform sand unloading cannot be achieved. At the same time, the sand and gravel unloading holes are easily blocked, which makes it impossible for the sand box to achieve displacement regulation of the upper structure. Summary of the Invention

[0004] The present invention discloses a multi-point dynamic dual-control combination device for deformation of a large-scale hollow truss structure, which aims to solve the technical problem that the existing dual-control device in the background technology slowly unloads the force through the double-sided jacks until the upper structure is subjected to force and the top of the sand box, and the sand box device automatically unloads sand by being subjected to force above the sand box. Since there are multiple sand and gravel unloading holes, uniform sand unloading cannot be achieved, and the sand and gravel unloading holes are easily blocked, which makes it impossible for the sand box to achieve displacement control of the upper structure.

When the guide cylinder 1006 slides in the limiting circular tube 1002, the elasticity of the extrusion spring 1003 makes the multiple arc rollers 1005 on the U-shaped support frame 1004 resist the outside of the guide cylinder 1006. The contact area between the arc roller 1005 and the outside of the guide cylinder 1006 is small, which reduces the friction on the guide cylinder 1006 and improves its service life.

[0049] Working principle: When unloading sand and gravel, the universal motor 905 is started at this time, and the corresponding linkage round rod 903 is driven to rotate by the universal motor 905, so that the adjusting gear 906 on the linkage round rod 903 drives the linkage round tooth plate 907 to make the remaining multiple adjusting gears 906 rotate at the same time, and the corresponding meshing linkage gear rods 909 are driven to slide inside the slot 908 by multiple adjusting gears 906, and the multiple linkage gear rods 909 drive the opening and closing sand unloading plate 910 to move, so that the sand discharge pipe 7 is opened, and then all the sand box inner tubes 4 are synchronously controlled to descend accurately, and then the double-sided jack bodies 12 at eight points are synchronously controlled to slowly unload the force until the upper structure is again subjected to the force on the top bearing plate on the sand box inner tube 4. 5, at this time, the upper load on the jack body 12 is reduced to 0kN; then all the sand box inner tubes 4 are synchronously controlled to drop accurately first; then the jack bodies 12 on both sides of the eight points are synchronously controlled to slowly unload the force until the upper structure is again subjected to force above the top bearing plate 5 of the sand box inner tube 4, at this time, the upper load on the jack body 12 is reduced to 0kN; repeat several times until the upper structure is completely separated from all the sand box top bearing plates 5. During the sand discharge process of the sand discharge pipe 7, the electric drive rod 807 is started to drive the sand discharge stud 809 on the sand discharge tooling frame 808 to move to one side of the sand discharge pipe 7, and then the screw motor 805 is started, and the screw 802 is driven by the screw motor 805 to drive the screw nut sliding seat 803. The sand unloading stud 809 on the sand unloading tooling frame 808 on the screw nut sliding seat 803 moves to the inside of the sand outlet pipe 7. When the top bearing plate 5 is subjected to force, it drives the sand box inner tube 4 to move downward inside the sand box outer tube 2. During the downward movement of the sand box inner tube 4, the multiple guide cylinders 1006 on the top bearing plate 5 slide inside the limiting circular tube 1002. At the same time, the arc roller 1005 rotates along on the U-shaped frame 1004 to limit the downward movement trajectory of the sand box inner tube 4. When the guide cylinder 1006 slides in the limiting circular tube 1002, the elasticity of the squeezing spring 1003 is used to make the multiple arc rollers 1005 on the U-shaped frame 1004 resist the outside of the guide cylinder 1006, and the sand box inner tube While the sand box 809 is moving downward, the intermittent start of the driving motor 814 drives the linkage clamping column 827 on one side of the linkage screw 813 to rotate, and the linkage clamping column 827 drives the rotating clamping tube 828 to rotate inside the sliding circular tube 826, so that the sand unloading stud 809 can accurately and intermittently unload the sand and gravel inside the sand box outer tube 2. When the linkage screw 813 rotates, the gear plate 817 rotates accordingly, and the convex plate 818 is driven to rotate in a circle through the rotating cylinder 816, so that the roller 825 on the push-pull support rod 829 drives the U-shaped push-pull rod 824, so that the sliding circular tube 826 drives the sand unloading stud 809 to impact horizontally back and forth inside the sand outlet pipe 7, thereby avoiding blockage of the sand outlet pipe 7 when unloading sand and gravel.
