FIG. 3 is a top view of the reaction frame of FIG. 1.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments thereof.
As shown in fig. 1-3, a bailey piece reaction frame device for prepressing a continuous beam 0# block bracket comprises three bailey piece reaction frames 30 arranged in parallel, wherein the axial direction of each reaction frame 30 is perpendicular to the axial direction of a pier body 90, a plurality of i-steel bolsters 11 are arranged below each reaction frame 30, a distribution beam 31 is arranged above each reaction frame 30, two rows of deformed steel bars 32 (also called deformed steel bars) are fixed on each distribution beam 31, and the lower ends of the deformed steel bars 32 are embedded in the pier body 90.
Equal fixed bracket 10 in two sides of pier shaft 90, a plurality of jacks 20 distribute on the bracket 10, and the distribution quantity and the distribution density of jack 20 are decided according to the particular case of bridge support bracket pre-compaction.
For the sake of firmness, the beret reaction frame 30 includes a plurality of (three in the drawing) parallel beret pieces 301 fixed together, which are also called beret frame and beret beam, and is formed by welding an upper chord, a lower chord, a vertical bar and an oblique bar, wherein the ends of the upper chord and the lower chord are provided with a male-female joint, and the joints are provided with pestle frame connecting pin holes, which are not described again in view of the prior art. The number of the Bailey pieces 301 can be adjusted according to the required structural strength, and the installation is more convenient at present.
Referring to fig. 2, for rigidity, two rows of the deformed steel bars 32 are disposed on both sides of the reaction frame 30, so that the reaction frame 30 is relatively fixed by being sandwiched between the two rows of the deformed steel bars 32.
Referring to fig. 1, the bracket 10 and the jack 20 are provided with i-shaped steel bolsters 11 for firmness.
The working principle is as follows:
when the device is needed to be used, the number of the required Bailey pieces 301 is calculated, the Bailey pieces 301 are spliced into the Bailey piece reaction frame 30, and the Bailey piece reaction frame 30 is fixed on the pier body 90 through the embedded deformed steel bar 32, the I-shaped steel bolster 11 and the distribution beam 31.
The jacks 20 are then activated for loading, observation and calculation, etc. See in particular chinese patent publication No. CN 211897860U.
The characteristics of this patent:
(1) saving material
The chinese patent publication CN211897860U not only consumes a lot of i-steel material, but also generates extra processing cost, and the truss loses use value after the pre-pressing is completed, and the bridge brackets have different designs, so that the turnover possibility is very small, which causes waste. The Bailey pieces are made of materials used for turnover, are light in weight, can be repeatedly used, and are beneficial to intensification of resource use. The material consumption of the scheme only comprises pre-buried finish rolling deformed steel bars, and other materials are used for hanging basket accessories.
(2) Reliable structure
The Bailey sheet belongs to a factory-made finished product standard part, has strong structural reliability, and avoids the welding quality defect of a self-made processing component. The single plates are light in weight and can be spliced, the hoisting and installation processes are flexible to set up and quick to install, the work efficiency is improved, and meanwhile, the construction risk is greatly reduced.
(3) Modular design and high adaptability
Bailey pieces can be assembled at will according to requirements, are adjusted in structural strength through the number of parallel trusses and adjusted in length through the number of segments, can be used for prepressing brackets with different cantilever lengths, and can meet various working conditions.
(4) The prepressing simulation effect is good
The structure has strong adaptability, can ensure enough length and width, basically realize the random arrangement on the bracket when arranging the jack, and has more real simulation of concrete load distribution and more accurate data.
In conclusion, the scheme is time-saving, labor-saving and cost-saving, convenient, rapid and safe, has a wide application range, and greatly improves the bracket prepressing process.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the overall concept of the present invention, and these should also be considered as the protection scope of the present invention.
