The removable factory building of arc-shaped steel pipe support
Technical field:
The utility model relates to a kind of when being applicable to penstock and making outdoor weld job and small-sized gold knot make the removable factory building of arc-shaped steel pipe support of welding.
Background technology:
At present, make in work progress at middle-size and small-size penstock, because penstock making amount is little, consider that factory building faces factors such as building the duration and whole total duration is shorter.Construction party is built the construction cost input for reducing to face, and generally can not plan comparatively expensive Lightweight metal plant or fixed welding shop; And penstock making welding quality is very strict to windproof, the rainproof measure requirement of on-the-spot actual condition, be to guarantee penstock welding quality, construction speed.Need special frock or veil to weld and carry out windproof, rainproof protection penstock, be convenient to the welder and carry out weld job; After the penstock welding, require veil is removed, removed fast, carry out follow-up construction or lifting operation.
The utility model content:
The purpose of this utility model is in order to overcome above-mentioned shortcoming, provide a kind of easy to make, not only can solve windproof, rainproof problem, and but also can substitute Lightweight metal plant and use function, simultaneously can also conveniently use, can move, do not affect penstock and make the operations such as subsequent handling and lifting, the removable factory building of arc-shaped steel pipe support in larger use space is arranged.
The purpose of this utility model is achieved like this:
The removable factory building of the utility model arc-shaped steel pipe support, comprise the wall frame that several four cast columns form, wall frame corresponding side surface has respectively two ends to be contained in respectively the crossbeam on corresponding four cast columns, the wall top of the trellis has the arc roof, on every four cast column bottom roller framves, roller is housed, adopt steel pipe to carry out frame manufacture, agent structure is four tubular column shapes, framework is firmly attractive in appearance, the outside adopts color steel watt to seal with C shaped steel with top, and monnolithic case is quite attractive in appearance, coordination, and base arranges the rolling train, need to lay track, track overburden pressure steel pipe circle zone; Both sides do not arrange gable, if in the time of need covering steel pipe, utilize manpower that this factory building is pushed into to use location, after work completes; This factory building is removed along covering track, completed the operations such as follow-up construction or lifting.
Four above-mentioned cast column cross-sections are shaped as square, and four cast columns are by four steel pipes and are positioned between four steel pipes and with some reinforced steel Combination Welding of adjacent steel-pipe welding, form respectively.
Above-mentioned crossbeam shape of cross section is triangle, and crossbeam is by three steel pipes and is positioned between three steel pipes and with some reinforced steel Combination Welding of adjacent steel-pipe welding, forms respectively.
Above-mentioned arc roof shape of cross section is square, and the arc roof is by four steel pipes and is positioned between four steel pipes and with some reinforced steel Combination Welding of adjacent steel-pipe welding, forms respectively, has good height requirement; From heavy and light, the characteristics such as intensity is large, span is large.
The utility model not only possesses all characteristics of Lightweight metal plant, but also possess shock resistance good, make that simple and fast, shock resistance are good, good rigidly, deformability be strong.The utility model has solved medium and small penstock and has made the work items that factory should not arrange the large-scale steel structure factory building; The problem such as windproof, rainproof that can solve that when welding run into, make design and construction little (1500t is following) for penstock; And On-site Welding Technology requires high place to arrange in field.The investment of the removable factory building of the utility model arc-shaped steel pipe support is low, it is convenient to remove, it is simple to install, and can repeatedly recycle, the feature of environmental protection is good, the life-span used long.The utility model has solved the problem of the penstock welding procedure that should not plan steel-structure factory building.The removable factory building overall weight of the utility model arc-shaped steel pipe support is little, and fabrication cycle is very short.The removable factory building floor installation of the utility model has the rolling train, only needs to lay 2 tracks, can complete the movement of factory building, strengthened the usable floor area of the removable factory building of arc-shaped steel pipe support, indirectly increased economic benefit, can move with track reusable, safe and efficient.

The specific embodiment:
Referring to Fig. 1, Fig. 2, Fig. 5, the removable factory building of the present embodiment arc-shaped steel pipe support, comprise the wall frame that several four cast columns 1 form.Wall frame corresponding side surface has respectively two ends to be contained in respectively the crossbeam 2 on corresponding four cast columns.The wall top of the trellis has arc roof 3.On every four cast column bottom roller framves 4, roller 5 is housed.
Referring to Fig. 3, Fig. 4, four cast column cross-sections are shaped as square.Four cast columns are by four steel pipes 6 and are positioned between four steel pipes and with some reinforced steels 7 Combination Welding of adjacent steel-pipe welding, form respectively.
Referring to Fig. 6, Fig. 7, the crossbeam shape of cross section is triangle.Crossbeam is by three steel pipes 8 and is positioned between three steel pipes and with some reinforced steels 9 Combination Welding of adjacent steel-pipe welding, forms respectively.
Referring to Fig. 8, arc roof shape of cross section is square.The arc roof is by four steel pipes 10 and is positioned between four steel pipes and with some reinforced steels 11 Combination Welding of adjacent steel-pipe welding, forms respectively.
Penstock stiffening ring maximum gauge 11.86m in the present embodiment, more than the removable factory building camber ratio of arc-shaped steel pipe support was set to 1:7m, span was 14m, maximum height 4.5m.
The removable factory building service routine of the utility model arc-shaped steel pipe support is as follows:
(1) the 38kg/m track is installed in penstock group circle, welding region, the factory building overall structure is positioned on track.During use, utilize manpower or hoist engine that the removable factory building of the utility model arc-shaped steel pipe support is moved to and uses position.
(2), after penstock has welded, utilize manpower or hoist engine that the removable factory building of the utility model arc-shaped steel pipe support is moved to steel pipe plant area clear area and get final product.
