In order to solve the problems of the technologies described above, the technical solution of the utility model is:
The steel jacket box of secondary load in the vertical accumulated loading test in the utility model cushion cap top, it is characterized in that: the mutual bolt of prefabricated standard steel plate that four side panels of described steel jacket box are vertically arranged by polylith forms, described prefabricated standard steel plate comprises steel frame and is welded on the steel plate of its lateral surface.
Further, the high 3.5m of above-mentioned prefabricated standard steel plate, wide 1.5m, the thick 8mm of steel plate.
Further, above-mentioned steel frame is welded into " day " font by angle steel.
Further, the long limit, both sides of above-mentioned steel frame offers several bolts hole respectively, and two adjacent bolt hole spacing are 0.5m, and topmost bolt hole and steel frame top end face, foot bolt hole and steel frame bottom face are all at a distance of 0.25m.
Further, longitudinal Screw arbor with nut at both-ends is being arranged near the bottom of described steel jacket box and horizontal, the vertical horizontal Screw arbor with nut at both-ends of a row and that is fixedly connected with of center.
Further, often arrange Screw arbor with nut at both-ends and comprise three Screw arbor with nut at both-ends, often arrange Screw arbor with nut at both-ends and be positioned at same plane.
Further, all horizontal support channel-section steel had for preventing Screw arbor with nut at both-ends from steel plate drawn distortion along steel jacket box outer circumferential side and in the end of same row's screw rod.
Compared with prior art, the utility model has following beneficial effect: this steel jacket box well can reduce the height of preloading, ensures the safety of preloading process; Simultaneously its working procedure and material requested less, splicing is convenient, greatly provides cost savings, the vertical preloading of cushion cap can be carried out smoothly under more convenient, economic, safe condition.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.

In figure: the prefabricated standard steel plate of 1-, 11-steel frame, 111-bolt hole, 12-steel plate, 21-Screw arbor with nut at both-ends, the horizontal Screw arbor with nut at both-ends of 211-, the longitudinal Screw arbor with nut at both-ends of 212-, 3-supports channel-section steel, 4-cushion cap, 5-base plate.
Detailed description of the invention
As shown in Fig. 1 ~ 5, the utility model is used for the steel jacket box of secondary load in the vertical accumulated loading test in cushion cap 4 top, comprise 24 blocks of prefabricated standard steel plates 1, each side panel of described steel jacket box forms by the mutual bolt of six blocks of prefabricated standard steel plates 1, described steel jacket box is rectangular, and described prefabricated standard steel plate 1 comprises the steel frame 11 in " day " font and is welded on the steel plate 12 of steel frame 11 lateral surface, and described steel plate 12 is long is 3.5m, wide is 1.5m, and thick is 8mm; Described steel frame 11 adopts 80 angle steel to be welded, and the described steel frame 11 in " day " font considerably increases the intensity of steel jacket box; The length of described steel jacket box entirety is 3.5m, and wide is 1.5m.
In the present embodiment, the long limit, steel frame 11 both sides of described prefabricated standard steel plate 1 is respectively equipped with seven bolts hole 111, two adjacent bolt hole 111 spacing are 0.5m, and topmost bolt hole 111 and steel frame 11 top end face, foot bolt hole 111 and steel frame 11 bottom face are all at a distance of 0.25m.
In the present embodiment, near the bottom of described steel jacket box with center is horizontal, vertical is fixedly connected with the horizontal Screw arbor with nut at both-ends 211 of a row and the longitudinal Screw arbor with nut at both-ends 212 of a row, described Screw arbor with nut at both-ends 21 adopts diameter to be the reinforcing bar of 20mm.
Screw arbor with nut at both-ends can either destroy for preventing it from spreading occurring in loading procedure, can not affect again hanging of sandstone and send.
In the present embodiment, because Screw arbor with nut at both-ends 21 runs through steel jacket box and steel plate 12 is thinner, the all horizontal reinforcement channel-section steel 3 had for preventing Screw arbor with nut at both-ends 21 from steel plate 12 drawn distortion along steel jacket box outer circumferential side and in the end of Screw arbor with nut at both-ends 21, also arrive, long No. 18 channel-section steels for 9m are added as support to prevent Screw arbor with nut at both-ends 21 from steel plate 12 is drawn distortion in the end of often arranging Screw arbor with nut at both-ends 21, described reinforcement channel-section steel 3 is arranged along steel jacket box side outer Thursday, bottom and middle part four roads respectively, totally eight roads, that is, channel-section steel 3 is strengthened by steel bushing case band jail in eight roads, certainly, the quantity strengthening channel-section steel 3 suitably can be increased according to operating mode.
Use procedure of the present utility model is as follows: after processing pre-buried steel component, bury pre-buried steel component and cushion cap 4 underground to construct and synchronously carry out, then welding supports channel-section steel and base plate 5, and then some blocks of prefabricated standard steel plates 1 are assembled into steel jacket box, two contiguous prefabricated standard steel plates 1 are mutually permanently connected through bolt, weld with base plate 5 bottom described steel jacket box, that is, lower surface bottom the steel frame 11 of 24 blocks of prefabricated standard steel plates 1 to be welded with base plate 5 or through bolted-on, then horizontal Screw arbor with nut at both-ends 211 and longitudinal Screw arbor with nut at both-ends 212 is set up respectively in the bottom of steel jacket box and center, and strengthen channel-section steel 3 at the exposed welding edges at steel jacket box outer circumferential side of Screw arbor with nut at both-ends, finally carry out the hierarchical loading of process of the test.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
