Embodiment Construction

[0035] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] figure 1 It is a diagram of a stent preloading device according to an embodiment of the present invention.

[0037] Such as figure 1 As shown, the present invention provides a support preloading device, which includes a synchronous flat jack 12, a reaction force frame, a steel wire rope 6, a rope tightener 4 and a support.

[0038] Wherein, the reaction frame comprises the upper beam 11 of the reaction frame and the lower beam 10 of the reaction frame, the lower beam 10 of the reaction frame and the upper beam 11 of the reaction frame are steel beams, and the upper beam 11 of the reaction frame is provided with a smaller steel beam. Fastener clamp (not in figure 1 Marked above), used to fix the wire rope 6.

[0039] The support includes a support pole 7 and a support cross bar 5 perpendicular to the support pole 7 .

[0040] Corres...

Abstract

The invention provides a support preloading device and method. The support preloading device comprises a synchronous flat-shaped jack, a counterforce frame, a steel wire rope, euphroes and a support; the counterforce frame comprises a counterforce frame upper beam and a counterforce frame lower beam; the support comprises support upright rods and support transverse rods which are perpendicular to the support upright rods; a corresponding support top bearing is arranged above every support upright rod; wood square columns are paved above the support top bearings; the counterforce frame lower beam is arranged above the wood square columns; the synchronous flat-shaped jack is arranged between the counterforce frame lower beam and the counterforce frame upper beam; a support bottom bearing is arranged between every support upright rod and a concrete layer surface which is poured on the support foundation; a steel wire connector is arranged between every support upright rod and the corresponding support bottom bearing; the steel wire rope which is provided with the euphroes at two ends strides over the counterforce frame upper beam; the two euphroes which are arranged at two ends of the steel wire rope are respectively hooked the steel wire rope connectors. The support preloading device and method is capable of solving the problems of self-non-elastic deformation and construction safety of the support.

Description

technical field [0001] The invention relates to the technical field of building construction, road and railway bridges and municipal building construction, and more specifically relates to a bracket preloading device and method for preloading formwork engineering of cast-in-situ concrete by using the reaction force frame technology. Background technique [0002] In housing construction, highway and railway bridges and municipal construction projects, many ancillary projects of the main body are constructed by the bracket method, and bracket preloading is an important link in bracket construction. [0003] At present, when using the bracket method for concrete pouring construction, especially when pouring low-altitude or high-altitude concrete structures such as concrete in beam bridge cantilever construction, in order to check the installation quality and overall bearing capacity of the bracket, and eliminate the inelastic deformation of the bracket, observe the bracket The ...
