A kind of non-damageable corrugated sheet engineering structures
Technical field
The utility model relates to the steel plate member of using for the lining cutting of bridge tunnel, underground vertical shaft, negative well engineering in the engineerings such as highway, municipal administration, railway, belongs to bridge, contains well engineering component technical field.
Background technology
In recent years, in the buried structure of the engineerings such as railway, highway, municipal administration, mine, and in the building of the engineerings such as the reinforcing of old bridges and culverts, highway tunnel, negative well, coal mine roadway, adopt in large quantities metal arc corrugated board structures to construct, more have superiority than traditional reinforced concrete structure, it lightweight, quick construction is all better than traditional structure cost or on the duration.In at present conventional corrugated board structures, there is concavo-convex ripple on corrugated sheet surface, on corrugated sheet plate face, there is connecting screw hole, the position of screw is positioned at crest top and the trough bottom of plate face, imbed after the soil body at corrugated sheet, through making mechanical test, crest and trough are stressed concentration zones, exist larger stress to concentrate, and screw is in crest and trough place, the tension of bolt and shearing resistance damage corrugated sheet screw sometimes, produce hole cracking phenomena, when serious, may cause the longitudinal whole round cracking of single plate face screw, the stressed of corrugated board structures exerted an influence, overall corrugated board structures is damaged, cause the damage of engineering structures, therefore be necessary to be improved.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of non-damageable corrugated sheet engineering structures, this corrugated sheet engineering structures is lightweight, intensity is high, speed of application is fast, can reuse, avoid the cracking phenomena of connecting screw hole, can in the engineerings such as tunnel, culvert, underground vertical shaft, negative well, use.
The technical scheme solving the problems of the technologies described above is:
A kind of non-damageable corrugated sheet engineering structures, it is connected to form by several curved metal corrugated sheets, adopts overlap joint rear by bolton between adjacent corrugated plate, and screw is positioned on the crest of corrugated sheet and the alternately inclined-plane of trough.
Above-mentioned non-damageable corrugated sheet engineering structures, described corrugated sheet engineering structures is connected and is assemblied into one by multiple monomer arc-shaped wave cards, the bellows-shaped of monomer arc-shaped wave card is sinusoidal circular arc ripple, or triangle ripple, or trapezoidal ripple, the flexibility of each monomer structure crooked radian and engineering structures matches, after assembled, be shaped as circle or oval or arch or the shape of a hoof, the screw that carries out at plate face two ends on corrugated sheet longitudinally connecting is two rows or three rows, and the screw that plate face both sides carry out laterally connecting is single row of holes.
The beneficial effects of the utility model are:
The connecting screw hole of adjacent corrugated plate of the present utility model is positioned on the crest of corrugated sheet and inclined-plane that trough replaces, avoid maximum stress concentrated position, prevent that screw is subject to ftractureing after bolt tractive, reduced the problem that corrugated sheet damages, be conducive to the safety and stablization in engineering structures later stage.Assembled rear circular, the arch of corrugated sheet engineering structures or the shape such as ellipse, shape of a hoof, it can accomplish 1.5 meters-20 meters across footpath, can in the engineering constructions such as tunnel, bridge, culvert, underground vertical shaft, negative well, apply, there is lightweight, the advantage such as intensity is high, speed of application is fast, can reuse, constructability.The utility model can adopt factory's centralization to produce, and job site rapid-assembling, is the Novel engineering member of the engineerings such as modern highway, municipal administration, railway.

Fig. 1 is monomer arc-shaped wave card structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is splicing structure stateful connection schematic diagram of the present utility model.
In figure, mark is as follows: corrugated sheet 1, screw 2, crest 3, trough 4.
The specific embodiment
In figure, show, the utility model is connected to form by several curved metal corrugated sheets 1, after adopting overlap joint between adjacent corrugated plate 1, use bolton, screw 2 is positioned on the alternately inclined-plane of the crest 3 of corrugated sheet 1 and trough 4. on the inclined-plane that the crest 3 that is positioned at corrugated sheet 1 due to connecting screw hole 2 and trough 4 replace, avoid maximum stress concentrated position, prevent that screw 2 is subject to ftractureing after bolt tractive, reduced the problem of corrugated sheet cracking.
In figure, show, the utility model is connected and is assemblied into one by multiple monomer arc-shaped wave cards, the bellows-shaped of monomer arc-shaped wave card is sinusoidal circular arc ripple, or triangle ripple, or trapezoidal ripple, the flexibility of each monomer structure crooked radian and engineering structures matches, after assembled, be shaped as circle or oval or arch or the shape of a hoof, the screw 2 that carries out at plate face two ends on corrugated sheet 1 longitudinally connecting is two rows or three rows, pitch of holes is 30-100mm, the screw 2 that plate face both sides carry out laterally connecting is single row of holes, and pitch of holes is 100-400mm.
The thickness of corrugated sheet 1 steel plate that an embodiment of the present utility model adopts is 2-10mm, and the section of corrugated sheet 1 is sinusoidal arc-wave or trapezoidal wave or triangular wave, and the pitch of waves is 230mm, and wave height is 64mm, after assembled moulding, is 1500~20000mm across footpath.
