Problems solved by technology

In the building jacking project, especially the slope adjustment and jacking of bridges, because of the gravity of the structure itself, it is inevitable that horizontal component forces will be generated. If the stability of the supporting bracket system cannot meet the needs of the jacking project, once the support If the bracket system tilts, the consequences will be unimaginable, so there is a huge potential safety hazard

Embodiment Construction

[0024] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] see Figure 1 ~ Figure 2 As shown, the jacking support system of the present invention mainly includes a group of jacking steel supports 1, a group of stable steel supports 2, and a connection between the jacking steel supports 1, the jacking steel supports 1 and the stabilizing steel supports 2. Between and form an integrated steel lattice structure 3. Wherein, the jacking steel supports 1 are arranged on the lower parts of the pistons of the jacks 4a and 4b respectively, and each jacking steel support 1 includes several steel cylinders 5a stacked one after another in the longitudinal direction, and the two steel cylinders adjacent to each other vertically Flange plates 6a are arranged between the 5a and fixed by bolts; the stable steel supports 2 are respectively arranged on one side of the jack 4, and each stable st...

Abstract

The invention discloses a jacking support system and a jacking support method. A jacking steel support formed by overlapping steel barrels is arranged below a jack; a stable steel support formed by overlapping steel barrels is arrange on the lower side of the jack; the jacking steel support and the stable steel support are horizontally, obliquely and longitudinally fixed together, thereby forming a steel grid form. Possible horizontal components occurring in a jacking process can be controlled through the stable steel support, so that the jacking support system is firmer and more reliable; a whole body is formed through steel grids, so that the structural safety in the jacking process can be ensured more effectively, jacking, sloping, descending and rectifying of a jacked building can be realized according to an expected procedure of people, and the effect of no reduction of the use function of the building is achieved after jacking.

Description

technical field [0001] The invention relates to jacking support technology, more specifically, to a support system and a support method for jacking. Background technique [0002] During the lifting process of general buildings (such as bridges, etc.), a set of support bracket systems are installed at the lower part of the jack, including steel supports, steel pads and leveling steel plates. After the jack has been raised for one stroke, the steel supports and steel pads in the support bracket system will also follow up. As the jacking height increases, the stability of the support bracket system is required to be higher. In the building jacking project, especially the slope adjustment and jacking of bridges, because of the gravity of the structure itself, it is inevitable that horizontal component forces will be generated. If the stability of the supporting bracket system cannot meet the needs of the jacking project, once the support If the bracket system tilts, the consequ...
