Abstract
The utility model discloses a protection canopy frame of a triangle-shaped trusswork. The protection canopy frame of the triangle-shaped trusswork comprises an upper beam body built on a steel pillar through an H-shaped steel beam. The upper beam body is the triangle-shaped trusswork. The protection canopy frame of the triangle-shaped trusswork solves the problems of heavy self weight and large deflection because the upper beam body is designed to be the triangle-shaped trusswork and has the advantages of being simple in structure and low in cost. Meanwhile, the triangle-shaped structure is more stable and not prone to rollover in movement. And an anti-deflection web member is arranged between two adjacent sets of the web members to further reduce the deflection of the triangle-shaped trusswork. The protection canopy frame of the triangle-shaped trusswork is applied to bridge construction.
Description
Technical field
The utility model relates to a kind of protecting canopy frame, particularly a kind of protecting canopy frame of triangular truss structure.
Background technology
At present, domestic town road construction and road transport network construction are just flourish, graded crossing and mutually pass through unavoidably, and therefore cantilever pouring also becomes the first-selection of construction.And the basis that protecting canopy frame is constructed as cantilever pouring is the most important thing, and the top beam body of general protecting canopy frame adopts following dual mode to build mostly:
The one, the I shape longeron, because the I-shaped steel longitudinal beam dead weight is larger, so after span strengthened, the amount of deflection of I-shaped steel longitudinal beam also can increase, for guaranteeing the height of top beam body, must increase the I-shaped steel longitudinal beam height, like this, the deadweight of I-shaped steel longitudinal beam further increases, material expends more, top beam body dead load strengthens and also can cause the corresponding increase of substructure material simultaneously, and therefore, the I shape longeron generally is applicable to the little bridge of span;
The 2nd, shellfish thunder sheet, by engineering experience, striding of Bailey beam structure directly generally can be greater than 20m.
In sum, stride the rail yard bridge for some Municipals, because its span is large and bridge floor is wide, so the top beam body that adopts I shape longeron and Bei Lei sheet to build is generally all inapplicable.And, the existing newly building bridge in after bridge construction is finished because top, suspension arm of crane can't be put to good use, so protecting canopy frame top beam body must could lift dismounting after being displaced to opening, and top beam body easily rollover in shifting process of adopting I shape longeron or shellfish thunder sheet to build brings risk to dismounting.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, a kind of protecting canopy frame that is applicable to the large bridge construction of span and the readily removable triangular truss structure of removing to be provided.
In order to realize above purpose, the protecting canopy frame of a kind of triangular truss structure that the utility model provides comprises top beam body, and top beam body is built on steel pipe post by the i iron crossbeam, and described top beam body is the triangular truss beam.This triangular truss beam deadweight is little, and amount of deflection is also little, is applicable to the large bridge construction of span; And triangular structure is more stable, is difficult for rollover in moving process.
In such scheme, described triangular truss beam comprises a upper chord and two lower chords, is fixedly connected with by web member between described upper chord and the lower chord.
In such scheme, described web member arranges take three as one group along described upper chord and lower chord longitudinal separation, and described three web members are interconnected to form triangular structure.
In such scheme, be connected with vertical capable of resisting deflection web member between the described web member of two adjacent groups, further reduced the amount of deflection of described triangular truss beam.
The beneficial effect that the technical scheme that the utility model provides is brought is: by top beam body is designed to the triangular truss beam, solved from the great and large problem of amount of deflection, simple in structure, cost is low; Simultaneously, triangular structure is more stable, is difficult for rollover in moving process; And, between the described web member of two adjacent groups, add vertical capable of resisting deflection web member, further reduced the amount of deflection of described triangular truss beam.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side-looking structural representation of Fig. 1;
Fig. 3 is the structural representation of triangular truss beam.
Among the figure, top beam body 1, i iron crossbeam 2, steel pipe post 3, upper chord 4, lower chord 5, web member 6, vertically capable of resisting deflection web member 7.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
As shown in Figure 1, the protecting canopy frame of a kind of triangular truss structure that the utility model provides comprises top beam body 1, and top beam body 1 is built on steel pipe post 3 by i iron crossbeam 2, and described top beam body 1 is the triangular truss beam.This triangular truss beam deadweight is little, and amount of deflection is also little, is applicable to the large bridge construction of span; And triangular structure is more stable, is difficult for rollover in moving process.Described triangular truss beam comprises a upper chord 4 and two lower chords 5, is fixedly connected with by web member 6 between described upper chord 4 and the lower chord 5.
Above-mentioned web member 6 arranges take three as one group along described upper chord 4 and lower chord 5 longitudinal separations, and described three web members 6 are interconnected to form triangular structure.Be connected with vertical capable of resisting deflection web member 7 between the described web member 6 of two adjacent groups, further reduced the amount of deflection of described triangular truss beam.
The utility model has solved from the great and large problem of amount of deflection by top beam body 1 is designed to the triangular truss beam, and simple in structure, cost is low; Simultaneously, triangular structure is more stable, is difficult for rollover in moving process; And, between the described web member 6 of two adjacent groups, add vertical capable of resisting deflection web member 7, further reduced the amount of deflection of described triangular truss beam.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
