Description
Technical Field
The utility model belongs to the technical field of bridge construction support appurtenance, especially, relate to a be used for bridge substructure construction support adjusting device.
Background
With the rapid development of national economy of China, the investment of infrastructure is accelerated, and the construction of bridge projects in mountainous areas is increased continuously. At present, what the vertical regulation of crossbeam adopted usually is that preformed hole on the pier stud, and the excellent support method of punching adopts jack or sand section of thick bamboo, and current adjusting device has the problem in following several aspects: the safety is low, because jack or sand section of thick bamboo and the relative independence of piercing rod, do not form effective connection between the two, and only have vertical restraint between the component, very easily appear because of the operating personnel mounted position is inaccurate, improper operation, the phenomenon that the vertical load transmission is eccentric and leads to the support to collapse exists great potential safety hazard. The operation degree of difficulty is big, and the operating efficiency is low, and because the control accuracy requires more during the support installation, need the technical staff whole journey to utilize measuring instrument cooperation operation personnel to carry out the installation operation. In the support unloading process, a plurality of fulcrums of the support cannot be accurately controlled to be simultaneously and vertically unloaded, the support is difficult to disassemble, and the operation efficiency is reduced. Taking a double-column pier capping beam support as an example, after a pier column penetrating rod is installed, at least one commander, one technician and four support operators need to install the supporting points firstly, place a jack or a sand cylinder on the supporting points, install the main beam of the support by utilizing a truck crane, and adjust the supporting points to the designed elevation according to unified command by the four operators, and finish fixing after checking that the vertical load transmission meets the requirements. And finally, a distribution beam, a bottom die, an operation platform and the like are installed to complete the erection of the support, so that a large amount of time is wasted, and the efficiency is low. The purchase cost is high, and if the mechanical jack is adopted as the adjusting device, the price is higher. The purchase price of a single 32T spiral mechanical jack is 900 yuan, and 3600 yuan is needed in total according to a group of four brackets of the double pier. The turnover loss is big, if adopt a sand section of thick bamboo as adjusting device, loses easily at the turnover in-process at first, and some parts are easy to take place to damage at the turnover in-process, especially the regulation hole of a sand section of thick bamboo, influence later stage ann and tear the operation open.
