Abstract
The utility model discloses a double twisted box type bending element, which comprises a top flange plate, a bottom flange plate, a left web and a right web, wherein horizontal partition boards, longitudinal partition boards and stiffening ribs are arranged in the element; the horizontal partition boards are vertically distributed at intervals in the horizontal position in the element, the longitudinal partition boards are distributed in the longitudinal position in the element, and the stiffening ribs are positioned at the faying points between the horizontal partition board and the top flange plate and between the horizontal partition board and the bottom flange plate. The double twisted box type bending element adopts thick plates, has high twist degree, large box-shaped cross section and wide application range, and can realize the modeling of structures with large span and twist degree and a plurality of novel buildings.
Description
Technical field
The utility model relates to a kind of box-type member, specifically relates to a kind of double-twist box-shaped bent member.
Background technology
High speed development along with construction work, structure and a lot of novel building moulding of a lot of super-spans have appearred, these structures and moulding are very complicated, in order to make structure adapt to the requirement of architectural image, just need some members in the structure to change along with the curvature changing of structure, these variations comprise the bending of member, reverse and abnormity, concrete structure can not be realized these moulding separately because of self is heavy with the later stage bearing capacity, the mode that adopts steel work to combine with concrete structure realizes at present, because steel work is easy to generate bigger stress in welding, local distortion appears in curved slab easily, therefore the box-shaped bent member of making at present is generally the thin-walled steel plate, and the casing cross section is also smaller, and torsion resistance is little, can't satisfy large span, the modeling structure of high twist degree.
The utility model content
Goal of the invention: the purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of double-twist box-shaped bent member to be provided.
Technical scheme: in order to realize above purpose, a kind of double-twist box-shaped bent member described in the utility model, comprise top flange plate, bottom wing listrium, left web, right web, also comprise lateral partitions, longitudinal baffle, stiffening rib, described lateral partitions uprightly is arranged on the lateral attitude of component inside at interval, be provided with the cavity in the middle of the lateral partitions, make things convenient for interior welds; Described longitudinal baffle is positioned on the lengthwise position of component inside, the utilization of dividing plate, and the face that has effectively fettered outside plate is out of shape outward; Described stiffening rib is positioned at the joint place of lateral partitions and top flange plate, bottom wing listrium, has effectively increased the holding capacity and the rigidity of member.
Described member sheet metal thickness is 25mm～100mm, and box section is 750mm * 2500mm～750mm * 4300mm, and box section is uniform section or variable cross-section.
Described member length-wise axis is the space curve of a multi-angle, many bend radius, and promptly the member length-wise axis is not a straight line, and not in same plane.
Because the restriction of traffic condition at present, the member entire length of plant produced is 7m～23m, and the bend radius minimum is 7m, and torsion resistance is 0 °～25 °.
Beneficial effect: a kind of double-twist box-shaped bent member that the utility model provides compared with prior art has the following advantages: owing to used lateral partitions and longitudinal baffle, the face that has effectively fettered outside plate is out of shape outward, makes the member section stress distribution even; Adopted stiffening rib, reduced the thick wide ratio of plate, effective width that can increasing section improves the utilization rate of material, makes structure effectively resist variation of temperature, the effect of wind load and earthquake; Because member has used the steel plate material, and member section is wide, torsion resistance is big, thereby can apply to wider scope, can realize the modeling structure of large span and high twist.
Description of drawings
Fig. 1 is the schematic diagram of a kind of structure of the present utility model;
Fig. 2 is a kind of cross section of the present utility model schematic diagram.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
A kind of double-twist box-shaped bent member shown in Figure 1, the outside is top flange plate 1, bottom wing listrium 2, left web 3, right web 4, form the uniform section distortion tubular element that cross sectional shape is a rectangle by the mode of welding, described component inside structure comprises lateral partitions 5, longitudinal baffle 6, stiffening rib 7 as shown in Figure 2; Described lateral partitions 5 uprightly is arranged on the lateral attitude of component inside at interval, and the centre is provided with square opening, makes things convenient for interior welds and processing; Described longitudinal baffle 6 is arranged on the lengthwise position of component inside, and described stiffening rib 7 is positioned at the joint place of lateral partitions 5 and top flange plate 1, bottom wing listrium 2;
The utility model can be produced the double-twist box-shaped bent member of different parameters on request, in the following example:
Member length is 23m, 25 ° of twists, and the bend radius in the distortion back member section straight amount length 2.4m is 8.0m;
Member length is 10m, 19 ° of twists, and the bend radius in the distortion back member section straight amount length 3.8m is 9.0m;
In the present embodiment, member can change size, flexibility and the torsion resistance in cross section according to the stressed and modeling requirement of reality.
