Abstract
The utility model provides a temporary support system for a steel truss. The temporary support system comprises full hall scaffold support platforms erected on the concrete ground. The length and the density of scaffolds at positions of steel truss fulcrums are larger than those of scaffolds at other positions, and a combined steel support is arranged along the tops of the scaffolds. According to the temporary support system, the length and the density of the scaffolds at positions of steel truss fulcrums are larger than those of the scaffolds at other positions, so that the system is flexible and changeable in height, high in rigidity and stable. The bearing support system formed by full hall scaffolds and the top combined steel support is simple to dismount, flexible and changeable, good in integrity and economic and reasonable; and support heights of the scaffolds can be changed continuously according to a fish-bellied curve of the steel truss during erection of the support system, and the mounting accuracy is high.
Description
Technical field
The utility model relates to steel truss construction field in the construction work, relates in particular to the steel truss temporary supporting system.
Background technology
Flourish along with exhibition industry, some comprehensive strong, arrange exhibits that high museum building is increasing flexibly, to these high museums buildings, require it inner spacious, and can present the visual effect of large space, this building all adopts the steel structural roof form of large span.
Most steel structural roof forms are comprised of fish-bellied type Variable Section Steel truss, the Steel Truss Beam node adopts cast steel node to be connected with seamless steel pipe, because the Steel Space Truss structure itself is that distortion is large, vertical rigidity relatively little " flexibility " structural system, therefore adopt steel truss by unit lifting, steel truss fulcrum height just changes with curve, the constructure scheme of whole unloading after the aerial welding.After the steel truss construction of roof system is finished, steel truss is all supported by temporary supporting, the bearing capacity of the single strong point performance curve of being constructed changes, and how reliable, changeable temporary support structure system is set guarantees that also safety and the installation accuracy of steel truss structure in work progress seems very important.
The utility model content
Technical problem to be solved in the utility model has provided the steel truss temporary supporting system, and solving in the large-span steel, steel truss fulcrum height just changes with curve and makes the safety of supporting construction and the problem that precision reduces.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of steel truss temporary supporting system is provided, comprise: set up the full hall scaffold support platform on concrete surface, the scaffold of steel truss position of the fulcrum is longer than the length of the scaffold of other positions, density is large, is provided with combined steel bracket along described scaffold top.
Further, the steel truss temporary supporting system also comprises jack, and described jack is arranged on the top of described combined steel bracket.
Further, be provided with the two-way horizontal bar at described steel truss position of the fulcrum.
Further, at the top of the scaffold of described steel truss position of the fulcrum the antiskid fastener is set.
Further, described full hall scaffold is comprised of many φ 48 steel pipes.
The steel truss temporary supporting system that the utility model provides, the scaffold that wherein is arranged on the steel truss position of the fulcrum is longer than the length of the scaffold of other positions, density is large, can make the high flexible of system changeable, rigidity is large and stable system., good integrity simple and easy, flexible and changeable by the load-bearing fulcrum system dismounting that full hall scaffold and top group mould assembly steel bracket form, economical rationality; And in setting up the process of support system, can the scaffold support height be changed continuously according to the fish-bellied type curve of steel truss, reach higher installation accuracy.
Description of drawings
The cross-sectional view of the steel truss temporary supporting system that Fig. 1 provides for the utility model embodiment;
The steel truss facade bent structure schematic diagram that Fig. 2 a provides for the utility model embodiment;
The steel truss cross section bent structure schematic diagram that Fig. 2 b provides for the utility model embodiment.
The specific embodiment
Below in conjunction with the drawings and specific embodiments a kind of steel truss temporary supporting system that the utility model proposes is described in further detail.According to the following describes and claims, advantage of the present utility model and feature will be clearer.It should be noted that, accompanying drawing all adopts very the form of simplifying and all uses non-accurately ratio, only is used for convenient, the purpose of aid illustration the utility model embodiment lucidly.
Core concept of the present utility model is, the steel truss temporary supporting system that the utility model provides, the scaffold that wherein is arranged on the steel truss position of the fulcrum is longer than the length of the scaffold of other positions, density is large, can make the high flexible of system changeable, rigidity is large and stable system., good integrity simple and easy, flexible and changeable by the load-bearing fulcrum system dismounting that full hall scaffold and top group mould assembly steel bracket form, economical rationality; And in setting up the process of support system, can the scaffold support height be changed continuously according to the fish-bellied type curve of steel truss, reach higher installation accuracy.
The cross-sectional view of the steel truss temporary supporting system that Fig. 1 provides for the utility model embodiment.With reference to Fig. 1, the steel truss temporary supporting system, comprise: set up the full hall scaffold support platform 11 on concrete surface, the scaffold of steel truss position of the fulcrum 12 is longer than the length of the scaffold of other positions, density is large, is provided with combined steel bracket 13 along described scaffold top.
For stating conveniently, will be called framed bent at the scaffold of steel truss position of the fulcrum 12.In the present embodiment, full hall scaffold adopts high 1.7m of step, is 1m, 8*1.375m, 1m along exhibition room long side direction vertical pole ' s span, is that the full hall scaffold platform form of 1m, 2*1.375m, 1m is set up along the exhibition room short side direction.According to steel structure hoisting situation afterwards, approximately 0.5 ~ 1 meter of full hall scaffold height distance steel truss lower edge rhombus frame bottom surface.
The steel truss facade bent structure schematic diagram that Fig. 2 a provides for the utility model embodiment; The steel truss cross section bent structure schematic diagram that Fig. 2 b provides for the utility model embodiment.With reference to Fig. 2 a and Fig. 2 b, framed bent adds one grade in length and breadth to the hyphen bar for every 0.85m on the basis of adopting high 1.7m of step at full hall scaffold, and in length and breadth to each two grades of vertical rods, vertical pole ' s span is that the form of 400mm, 200mm, 400mm is set up in the neutral gear position increase of 1m.For increasing safety guarantee, at the framed bent strong point top two-way horizontal bar 21 is set, and antiskid fastener 22 is set at the top, at the framed bent top combined steel bracket is set, jointly form support stand with jack, when shelving combined steel bracket, should be with combined steel bracket as far as possible near framed bent vertical rod place, to reduce the moment of flexure of cross bar.
Obviously, those skilled in the art can carry out various changes and modification to utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
