Description
Technical Field
The utility model relates to a static load test girder, in particular to a jack inverted embedded type static load test girder.
Background
An existing jack embedded type static load test girder is provided with an upward jack piston rod. When the hydraulic loading device works, the connecting bolts are loosened firstly, so that the jack is separated from the main beam body, and then hydraulic oil is input to the jack to load. This technique suffers from the following disadvantages: firstly, the connecting bolts are loosened when the main beam works, so that the jack is separated from the main beam body. In the non-working state, the connecting bolts are screwed again to integrate the jack and the main beam Liang Tilian. The operation is troublesome; secondly, the bottom of the girder body is provided with holes for ensuring the running of the jack cylinder body, and the size of the holes on the lower flange of the girder body is overlarge, so that the bending strength of the girder body is seriously weakened, and the girder strength is not improved.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a jack inverted embedded type static load test girder. The utility model has compact structure and reasonable structure, avoids repeated loosening and tightening of the connecting bolts, reduces the size of the opening at the bottom of the girder body and reduces the adverse effect on the strength of the girder body.
In order to achieve the purpose of the utility model, the utility model adopts the following technical scheme:
the main girder comprises a main girder body, wherein the main girder body is formed by welding an H-shaped steel girder, a counter-force plate and a supporting rib into a whole, a jack embedding hole is formed in a web plate of the H-shaped steel girder, the counter-force plate is arranged at the upper edge of the jack embedding hole, a connecting bolt hole is formed in the counter-force plate, the supporting rib is arranged on the web plate of the H-shaped steel girder at the upper part of the counter-force plate, and a piston telescopic hole is formed in the lower flange of the main girder body; the main beam further comprises a jack and a connecting bolt, a screw hole for the connecting bolt to screw in is formed in the bottom of the cylinder body of the jack, and the jack is inversely fixed on the counter-force plate through the connecting bolt.
The utility model has the beneficial effects that:
1) The utility model has compact structure and convenient use, and the jack and the main beam body are always connected into a whole no matter in a working state or a non-working state, and the connecting bolt does not need to be repeatedly loosened and screwed.
2) Compared with the prior art, the size of the opening of the lower flange is correspondingly reduced, and adverse effects on the bending strength of the girder body are also reduced.

Description of the embodiments
The technical solutions in the embodiments of the present utility model will be described below with reference to the accompanying drawings in the embodiments of the present utility model.
As shown in fig. 1 to 4, the main girder comprises a main girder body, wherein the main girder body is formed by welding an H-shaped steel girder 1, a counter-force plate 2 and a support rib 3 into a whole, a web plate of the H-shaped steel girder 1 is provided with a jack embedding hole, and a lower flange of the H-shaped steel girder is provided with a piston telescopic hole; the counter-force plate 2 is provided with bolt holes; the upper part of the counter-force plate 2 is provided with a supporting rib 3.
As shown in fig. 1-4, the main beam further comprises a jack 5 and a connecting bolt 4, wherein a screw hole for screwing the connecting bolt 4 is formed in the bottom of the cylinder body of the jack 5.
As shown in fig. 1 to 4, the main beam is formed by integrating the jack 5 with the main beam Liang Tilian by the connecting bolt 4.
The working process of the utility model is further described with reference to the accompanying drawings.
The main beam and other required equipment were mounted in place prior to the static load test, as shown in fig. 5. When the test starts, hydraulic oil is positively input to the jack 5, the piston extends downwards through the telescopic hole, when the piston is propped against the load plate 6, the cylinder body of the jack 5 and the main girder body are propped upwards, and when the main girder body is propped against the load 8, the load is started to be applied to the test object 7. After the test is finished, oil is reversely supplied to the jack 5, the equipment can be disassembled after the piston is retracted, and then the station is shifted. The jack 5 is integral with the main beam Liang Tilian throughout the process.
