Description
Technical field
Many, high-rise building steel structure industry that the utility model relates to concrete relates to a kind of firm support that is used for the steel work flooring.
Background technology
At present, in steel work flooring work progress, just supported the supporting part as the flooring working load, its length, cross section type selecting will meet different flooring room unit requirements, to same engineering, need miscellaneous bracing frame; And for different engineerings, the bracing frame that early investment is made can not be reused, and this certainly will increase the construction cost of flooring formwork project, also increases the difficulty that just supports on-the-spot circulation control.
Summary of the invention
The utility model technical problem to be solved is to propose to above-mentioned prior art a kind of simple in structure, installs and removes the firm support that is used for the steel work flooring of convenient, safe and reliable and economical rationality.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
Be used for the firm support of steel work flooring, it is characterized in that including firm supporting component, described firm supporting component includes standard knot or/and expansion coupling, and to regulate firm bearing length, expansion coupling is positioned at a side of standard knot and inserts standard knot and pass through bolt.
Press such scheme, the cross section of described standard knot and expansion coupling is that square, square type, round, ellipse, polygonal, triangular form, grooved, L type or H type are to form firm supporting component of plane frame type or the firm supporting component of space truss type.
Press such scheme, the standard knot length of described firm support is 2500mm ~ 5000mm, and expansion coupling is 1000mm ~ 2000mm, satisfies the standard width of a room in an old-style house requirement of span 1000mm ~ 6500mm between self-contained flat through combination.
Press such scheme, the length of socket is more than or equal to 250mm between described expansion coupling and the standard knot.
Press such scheme, be connected with web member on the standard knot through being arranged on expansion coupling between the firm supporting component of described space truss type, just support to form adjustable space truss type.
The standard knot of the utility model is to make by the modulus of the building standard standard width of a room in an old-style house; The material that can adopt: steel, aluminium, timber or plastics, its length is fixed, and the room unit flooring that is adapted to the standard standard width of a room in an old-style house just supports; In the case, this standard knot can directly use; When room unit standard width of a room in an old-style house size is nonstandard, can realize instructions for use through the combination of standard knot and expansion coupling, because of the length of its combination can be regulated arbitrarily, so can realize the firm bearing length that any room unit standard width of a room in an old-style house is required.
The standard knot of the utility model is to be connected through the mutual cover between them to realize what random length was regulated with expansion coupling; When adjusting length meets the requirements; Position overlapping is fixed with bolt, and is safe and reliable for guaranteeing, the overlapping length of standard knot and expansion coupling must not be lower than 250mm; Fixed knot uses when being used for two standard knot spreading requirements, applies to the firm support than large bay room unit floor template.
The beneficial effect of the utility model: can realize Fast Installation and dismounting, construction weight is light, simple to operate, can with floor beam construction operation simultaneously, keep synchronously with the agent structure progress, satisfy the requirement that the high-rise steel structure construction is fast, the cycle is short and quality is high.The utility model is rational in infrastructure, and the member conversion is easy; Safety, stability, compliance are strong, and concrete manifestation is following:
1) the utility model simple structure, its material are the section bar that can conveniently purchase on the market or simply process;
2) the utility model is in light weight, is generally about 50 ~ 65kg, and two workmans can carry, installation and removal, need not lifting appliance, high efficiency;
3) the utility model applicability is strong, and just bearing length can be regulated arbitrarily, adapts to any building construction standard width of a room in an old-style house template and supports requirement, and to Projects with Different, the utility model all can use, and need not particular items is designed and make specific firm support;
4) the utility model is with low cost, mainly has benefited from them and can reuse, and loss is few, supports with other floor template and compares, and very strong competitiveness is arranged;
5) the utility model component compatibility is strong, and field control is easier to realize bulk transport, installation and removal.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation, but can not constitute restriction the utility model.
Be used for the firm support of steel work flooring, include firm supporting component, just the length of supporting component can be regulated; Described firm supporting component comprises standard knot 1 and expansion coupling 2 (standard knot and expansion coupling also can use separately); Expansion coupling is positioned at a side of standard knot, fixes through inserting in the standard knot and by bolt 3, and the length of socket is more than or equal to 250mm between described expansion coupling and the standard knot; Through the firm overall length that supports of flexible scalable; Wherein said firm support standard knot length is 2500mm ~ 5000mm, and expansion coupling is 1000mm ~ 2000mm, satisfies the standard width of a room in an old-style house requirement of span 1000mm ~ 6500mm between self-contained flat through combination.
If the more piece standard knot then is connected through fixed knot between the standard knot.
The standard knot of described firm support and the cross section of expansion coupling can be square, square type, garden type, ellipse, polygonal, triangular form, grooved, L type or H type.Shown in accompanying drawing 1-2, the cross section of standard knot is a H shaped steel, and the cross section of expansion coupling is a rectangular tube; Shown in Fig. 3-4, the cross section of standard knot is a rectangular tube, and the cross section of expansion coupling is a rectangular tube; Shown in Fig. 5-6, the cross section of standard knot is the garden pipe, and the cross section of expansion coupling is the garden pipe;
Be connected with web member 4 on the standard knot as upper chord and lower chord and through being arranged on expansion coupling between the described firm supporting component, to form length adjustable spatial triangle and rectangle trussed construction, like Fig. 7-10.
The change in 1.5m ~ 5.5m scope basically of steel work floor face time case bay is to be shelved between the secondary beam because of just supporting, and inferior case bay has directly determined the length of selecting for use of steel support.
The application prospect of the utility model
That this structure is mainly used in is many, high level and superelevation layer structural steelwork, is adapted to any structural steelwork project.Estimate according to employer's organization; In the whole nation 5 years from now on, annual at the about Wan Duo in the of 3000 of the superelevation layer steel building area ㎡ that builds, like whole employing native systems; Can reduce about 10,000,000,000 RMB of construction cost in 5 years, this does not also comprise multilayer, high level and other steel work floor engineering; Even if popularizing area only accounts for 10%, also there are 10 hundred million.It is thus clear that the exploitation and the utilization of native system have a extensive future, the promotion and application of this project simultaneously also meet the industrial policy of China's low-carbon environment-friendly.
