Abstract
The utility model relates to a combined box truss girder with corrugated steel webs, which mainly solves the technical problem of the restriction of the width of the box truss girder in the bridge construction. The combined box truss girder with corrugated steel webs comprises a top plate and a bottom plate with prestressing reinforced concrete structures, , and vertical type corrugated steel webs on the two sides of the combined box truss girder, wherein the top plate is provided with an overhanging cantilever side flank; inclined struts are arranged at regular intervals between the cantilever side flank of the top plate and the bottom plate; and the inclined struts are arranged at the outside of the vertical type corrugated steel webs. Because the inclined struts are arranged at the outside of the vertical type corrugated steel webs, the utility model can effectively and reasonably transmit the force supported by the transverse cantilever of the top plate to the bottom plate, thereby widening the width of the box truss girder and expanding the application area of the box truss girder in the bridge construction.
Description
Technical field
The utility model relates to the bridge construction main member, especially is applicable to a kind of girder building unit of wide cut bridge.
Background technology
In the present bridge construction, two kinds of form of structure of the steel-concrete combined box beam of common employing prestressed concrete box girder or Wavelike steel webplate; Its beam is supported by support column, and then on beam surfacing.Its two outsides, road surface are cantilever structure.When road surface wide cut design broad, also require the wide cut of beam to widen, thereby make the lateral stressed bigger of beam, higher to the force request of beam itself, when the horizontal wide ratio increase of beam, lateral stressed very unfavorable to beam.Along with expanding economy, the design width of bridge on highway generally reaches 25-26m at present, adopts separate type double width bridge, and the single width width is at 12-13m; And the bridge of in city expressway, building, its Breadth Maximum may reach more than the 30m, and the single width width reaches more than the 15m.In the wide cut bridge construction, above-mentioned two kinds of structures all are unfavorable for the lateral stressed of bridge.Even if adopt the steel-concrete combined box beam of tilting Wavelike steel webplate, its bridge wide cut can not be wide, and wide on the one hand bridge requirement component strength or rigidity are higher, bring cost to increase at aspects such as materials; On the other hand, because the performance limitations of tilting Wavelike steel webplate own, its angle of slope is subjected to certain restriction, thereby has limited its width.
Technology contents
The utility model mainly solves the case beam technical problem that its wide cut is restricted in bridge construction, and then a kind of corrugated steel web plate composite box trusses of suitable wide cut bridge is provided.This case trusses is particularly suitable for the super wide bridge that single width surpasses 15m.
Corrugated steel web plate composite box trusses of the present utility model is achieved through the following technical solutions: it includes the top board of prestressed reinforced concrete structure and the vertical type Wavelike steel webplate of base plate and both sides, its top board has overhanging cantilever flank, the two ends up and down of its Wavelike steel webplate are stretched into respectively in top board and the base plate, Wavelike steel webplate by top board, base plate and both sides constitutes the case beam, cantilever flank at top board is provided with diagonal brace every a determining deviation between base plate, this diagonal brace is in the outside of vertical type Wavelike steel webplate.
Have an angle of slope between above-mentioned diagonal brace and the vertical type Wavelike steel webplate, this angle of slope is 15～50 degree.
Above-mentioned diagonal brace evenly is provided with along the length direction of case beam; Spacing between the adjacent diagonal brace is 1000～5000mm.
Combination box trusses of the present utility model is owing to add diagonal brace in the vertical type Wavelike steel webplate outside, form common stress system by top board, Wavelike steel webplate, base plate, diagonal brace, by diagonal brace the power that the horizontal cantilever of concrete roof (the Wavelike steel webplate outside) is born reasonably is passed to base plate, thereby can widen jib-length, widen the wide cut of case beam, compare with same case beam, its wide cut increment can reach about 40%, and stressed reasonable.As by at Wavelike steel webplate arranged outside diagonal brace, the Breadth Maximum of single box single chamber case beam can be increased to 18-20m by 15m, can build the wide cut bridge that width surpasses 40m, expanded the range of application of case beam in bridge construction.
Description of drawings
Fig. 1 is a cross-sectional structure schematic diagram of the present utility model.
The specific embodiment
Referring to Fig. 1, corrugated steel web plate composite box trusses of the present utility model includes the top board 1 of prestressed reinforced concrete structure and the vertical type Wavelike steel webplate 3 of base plate 2 and both sides, the top board of this reinforced concrete structure and base plate can adopt prestressed reinforcement etc., its arrangements of reinforcement etc. carry out according to top, bottom slab stress situation, stressed size etc., and are identical with existing case beam.Its top board 1 has overhanging cantilever flank, the two ends up and down of its Wavelike steel webplate 3 are stretched into respectively in top board 1 and the base plate 2, Wavelike steel webplate 3 by top board 1, base plate 2 and both sides constitutes the case beam, cantilever flank at top board 1 is provided with diagonal brace 4 every a determining deviation between base plate 2, this diagonal brace is in the outside of vertical type Wavelike steel webplate 3, helps stressed the reaching on the base plate with top board cantilever flank.These diagonal brace two ends can be connected with base plate with top board with built-in fitting in the base plate by being embedded in top board.
Have an angle of slope between described diagonal brace 4 and the vertical type Wavelike steel webplate 3, this angle of slope is 30 degree.
Described diagonal brace evenly is provided with along the length direction of case beam; Spacing between the adjacent diagonal brace is 2400mm.
Claims (3)
1, the corrugated steel web plate composite box trusses, include the top board (1) and the base plate (2) of prestressed reinforced concrete structure, and the vertical type Wavelike steel webplate (3) of both sides, its top board (1) has overhanging cantilever flank, the two ends up and down of Wavelike steel webplate are stretched into respectively in top board (1) and the base plate (2), by top board (1), the Wavelike steel webplate (3) of base plate (2) and both sides constitutes the case beam, it is characterized in that: the cantilever flank of top board (1) between base plate (2) every a determining deviation setting diagonal brace (4), this diagonal brace (4) is in the outside of vertical type Wavelike steel webplate (3).
2, corrugated steel web plate composite box trusses according to claim 1 is characterized in that: have an angle of slope between above-mentioned diagonal brace (4) and the vertical type Wavelike steel webplate (3), this angle of slope is 15～50 degree.
