Description

Technical Field

[0001] The utility model relates to the technical field of building jacking equipment, in particular to an alternating jacking structure of a building. Background Art

[0002] At present, in the alternating jacking process of previous buildings (such as bridges, etc.), the connection structure of the lattice steel support is: the main steel support and the longitudinal and transverse connections are welded through flanges. This method has a large overall rigidity and is suitable for the overall jacking support system. However, in the alternating jacking process, the lattice steel support will be divided into two groups, A and B. When the A group of steel supports are subjected to vertical loads and the B group is unloaded, the A group of steel supports will produce vertical deformation under the jacking load, so that the longitudinal and transverse connections between A and B will be deformed synergistically. This situation is more obvious in the support system with a higher height. When the B group of steel supports will be passively stressed, it may even cause the connection between A and B to be destroyed, so that the overall lattice steel support fails, affecting the structural safety during the jacking process, and there are huge safety hazards. In addition, the steel cylinder clamps used in the main steel support are usually installed with bolts or fasteners, but the steel cylinder clamps are loose during use but are not discovered and repaired in time. The loose steel cylinder clamps will reduce the stability of the building support body and increase the risk of collapse or collapse, thereby posing a threat to construction personnel and the surrounding environment.

[0028] Example

[0029] like Figure 1-7 As shown, the utility model proposes an alternating jacking structure of a building, including a steel support A component 1 and a steel support B component 2. During the jacking process, as the steel support A component 1 and the steel support B component 2 are raised, a longitudinal and transverse connecting component 3 that can slide relatively is added at every height, which can not only ensure the stability of the overall support, but also reduce the coordinated deformation of the steel support A component 1 and the steel support B component 2 and the longitudinal and transverse connecting component 3 during the alternating jacking process. Thus, a reliable and stable alternating jacking support system is formed. A section is provided on the steel support A component 1 and the steel support B component 2 for the connection mechanism to be installed and limited. The limit position is to prevent the connection mechanism from being installed too high or too low on the steel support A component 1 and the steel support B component 2. It also includes: longitudinal and transverse connection components 3 connected by multiple groups of transverse supports, which are arranged between the steel support A component 1 and the steel support B component 2; the steel support A component 1 and the steel support B component 2 reduce the coordinated deformation between the longitudinal and transverse connection components 3 through vertical loads, and the connection between the steel support A component 1, the steel support B component 2 and the longitudinal and transverse connection components 3 is provided with a connection mechanism to reduce the coordinated deformation; a reminder mechanism is arranged on the steel support A component 1 and the steel support B component 2 for timely reminding the connection mechanism of safety hazards.

[0030] Further, the connection mechanism includes a steel cylinder clamp 7 at the connection of the steel support A component 1, the steel support B component 2 and the longitudinal and transverse connection component 3. The steel cylinder clamp 7 refers to a device or structure used to reinforce and stabilize the steel cylinder (also called a steel barrel). A dust cover 4 is provided on the outside of the steel cylinder clamp 7. A modified polytetrafluoroethylene slide plate 5 is provided between the steel cylinder clamp 7 and the steel support A component 1 and the steel support B component 2. An adhesive is applied between the steel cylinder clamp 7 and the modified polytetrafluoroethylene slide plate 5. The adhesive is a substance that can bond two or more objects together. They play a key role in various applications, from glue in daily life to composite material manufacturing in industry. A thick slide plate 6 is also provided between the modified polytetrafluoroethylene slide plate 5 and the outer wall of the steel support A component 1 and the steel support B component 2. Silicone grease is applied between the modified polytetrafluoroethylene slide plate 5 and the thick slide plate 6. Silicone grease is a grease mixed with silicon oxide and organic resin, which is usually used to lubricate and prevent friction between metal parts. The outside of the steel tube clamp 7 is provided with a lock buckle for installing the longitudinal and transverse connection components 3.

[0031] Among them, the prompt mechanism includes a top ring 8 fixedly connected to the top of the steel tube clamp 7, and a plurality of first telescopic grooves 81 and second telescopic grooves 82 are arranged linearly and connected inside the top ring 8. The inside of the first telescopic groove 81 is connected with a sliding block 83, and glue is dotted between the sliding block 83 and the first telescopic groove 81. The inside of the first telescopic groove 81 is provided with a second spring 89 for pushing the sliding block 83 against the outer wall of the steel support A component 1 or the steel support B component 2. The function of the second spring 89 is to make the sliding block 83 automatically snap into the gap when a gap is generated between the steel tube clamp 7 and the steel support A component 1 and the steel support B component 2, thereby starting the element in the second telescopic groove 82.

[0032] Furthermore, the prompt mechanism also includes an insert block 86 fixedly connected to the sliding block 83 and movably passing through the second telescopic slot 82, the insert block 86 is movably connected to the second spring 89, one end of the second spring 89 is fixedly connected to the sliding block 83, and the other end of the second spring 89 is fixedly connected to the inner wall of the first telescopic slot 81, and the second telescopic slot 82 is movably connected with a sliding block 84 inside, and the top of the sliding block 84 is fixedly connected with a first spring 85 for resisting the inner wall of the second telescopic slot 82 and then ejecting the sliding block 84 from the second telescopic slot 82, and the function of the first spring 85 is to automatically eject the sliding block 84 that is not stuck from the second telescopic slot 82, and then make the sliding block 84 available for the staff to check in time. The sliding block 84 is provided with a slot 88 for it to be inserted into at one end close to the insert block 86, and the top of the sliding block 84 is provided with a connecting rope 87 located in the first spring 85, and the color of the connecting rope 87 can be relatively conspicuous, so that the staff can quickly check it. One end of the connecting rope 87 is fixedly connected to the inner wall of the second telescopic groove 82 , and the other end of the connecting rope 87 is fixedly connected to the sliding block 84 .

[0033] In this embodiment, a reliable and stable steel support A component 1 and a steel support B component 2 are installed at the bottom of the building to be jacked up, and then a section of the steel support A component 1 and the steel support B component 2 is left for the installation of the connection mechanism and a limit position. Then, two semicircular modified polytetrafluoroethylene slide plates with suitable widths are customized, and they are fixed to the inner walls of the two semicircular steel cylinder clamps 7 by applying adhesive between the polytetrafluoroethylene plates. Then, silicone grease is applied between the two semicircular steel cylinder clamps 7 of the modified polytetrafluoroethylene slide plate 5 in the connection mechanism section of the steel support A component 1 and the steel support B component 2 to reduce friction. The longitudinal and transverse connection components 3 are installed on the outside of the steel cylinder clamp 7 by welding or locking, so that the longitudinal and transverse connection components 3 can be made reliable and stable. Then, the lower foundations of the steel support A component 1 and the steel support B component 2 have reliable support to ensure that the height of the longitudinal and transverse connection components 3 does not change during the alternating jacking process. Finally, during the jacking process, as the steel support A component 1 and the steel support B component 2 are raised, a relatively slidable longitudinal and transverse connecting component 3 is added at every certain height, which can not only ensure the stability of the overall support, but also reduce the coordinated deformation of the steel support A component 1 and the steel support B component 2 and the longitudinal and transverse connecting component 3 during the alternating jacking process, thereby forming a reliable and stable alternating jacking support system;

[0034] When the steel tube clamp 7 is installed on the steel support A component 1 and the steel support B component 2, the bolts on the steel tube clamp 7 are tightened by a tool so that the inner wall of the steel tube clamp 7 is tightly attached to the outer wall of the steel support A component 1 or the steel support B component 2, and at the same time, the end of the sliding block 83 protruding outside the steel tube clamp 7 first abuts against the outer wall of the steel support A component 1 or the steel support B component 2, and the glue dotted between the sliding block 83 and the first telescopic groove 81 is broken by tightening the tool. At this time, the sliding block 83 is ready to go in the first telescopic groove 81. When the steel tube clamp 7 is loosened on the steel support A component 1 or the steel support B component 2, a gap will be generated between the inner wall of the steel tube clamp 7 and the outer wall of the steel support A component 1 or the steel support B component 2. At this time, the sliding block 83 moves toward the direction of the steel support A component 1 or the steel support B component 2 through the elastic thrust of the second spring 89, until the sliding block 83 drives the plug block 86 to disengage from the slot 88 at one end of the sliding release block 84, and then the sliding release block 84 is subjected to the elastic thrust of the first spring 85, so that the sliding release block 84 is suspended on the outer wall of the steel support A component 1 or the steel support B component 2 by the connecting pull rope 87. The staff can visually check the suspended sliding release block 84, and then deal with the loose steel tube clamp 7 in time to avoid danger.
