Of antinode shaped steel, make the steel arch-gate of girder
Technical field
The present invention relates to hydraulic engineering gate technical field, relate in particular to the improvement structure that a kind of girder to Segment gate adopts corrugated web.
Background technology
Existing Segment gate comprises curved panel and brace summer, and wherein brace summer is many row's structures.Because brace summer is for for i iron, and be arranged in parallel between adjacent supports beam, the curved panel intensity between adjacent beams a little less than, need the brace summer of higher density, more many processing capacities and the steel of having increased of brace summer quantity.For improving the bonding strength between brace summer and curved panel, need between each brace summer and curved panel, adopt the support rib of many vertical weldings to be connected, greatly increased working strength, and the welding precision that respectively supports rib is had relatively high expectations, difficulty of processing is large, manufacturing cost is high, large from weight, consumes steel enormous amount.
Summary of the invention
The object of this invention is to provide a kind of Segment gate of doing girder with antinode shaped steel, for improving curved panel intensity, reduce density and the quantity of support beam structure, thereby when improving or keeping original requirement of strength, cut down finished cost and labour intensity as far as possible.
For achieving the above object, the present invention adopts following technical scheme: a kind of steel arch-gate of making girder of antinode shaped steel, comprises that curved panel and solid welding are at least two arc brace summers of curved panel land side; Described arc brace summer is sinusoidal wave web grider, or is trapezoidal wave web grider; Described sinusoidal wave web grider or comprise upper flange, lower wing plate and web for trapezoidal wave web grider; The web of sinusoidal wave web grider is sinusoidal wave web, and the web of trapezoidal wave web grider is trapezoidal wave web; At the land side of curved panel two auxiliary beams of solid welding at least, auxiliary beam is with described sinusoidal wave web grider or trapezoidal wave web grider is vertical is connected, at least four vertical tie point positions, be fixed with respectively fork, on same sinusoidal wave web grider or trapezoidal wave web grider, fixing two or two ends with upper pendulum bar cross and are fixed together, this end crossing is hinged on base by bearing pin, and the land side of steel arch-gate comprises two ends that cross and two bases.
The upper flange of described sinusoidal wave web grider or trapezoidal wave web grider and lower wing plate are linear pattern, or are shaped form, or fold-line-shaped, the parallel distribution of adjacent corrugations web shaped steel or be interspersed or symmetrical.
The invention has the beneficial effects as follows:
1, the present invention adopts sinusoidal wave web grider or trapezoidal wave web grider as the brace summer of Segment gate, upper flange and the lower wing plate of sinusoidal wave web grider or trapezoidal wave web grider mate with curved panel, so, sinusoidal wave web grider or trapezoidal wave web grider are when keeping arc-shaped bend, its web is sinusoidal wave web or trapezoidal wave web, thereby brace summer has Curve Design in horizontal and bus, thereby has improved self intensity and the support strength to curved panel, and has improved moment of inertia.
2, with respect to existing common Segment gate, the present invention no longer needs to support the booster action of rib, can reduce in a large number the use amount of brace summer and use density.
3, the degree of depth on flashboard (highly) of corrugated beams can regulate according to actual loading situation, in same requirement of strength situation, can greatly reduce construction volume and construction intensity, a large amount of saving steel use amounts.

Number in the figure 1 is curved panel, and 2a is sinusoidal wave web grider, and 2b is trapezoidal wave web grider, and 3 is auxiliary beam, and 4 is fork, and 5a is sinusoidal wave web, and 5b is trapezoidal wave web.
the specific embodiment:
Below in conjunction with accompanying drawing, the invention will be further described.
Embodiment 1: the first is made the steel arch-gate of girder of antinode shaped steel, referring to Fig. 1-Fig. 5, in backwater one side of curved panel 1, is welded with the sinusoidal wave web grider 2a of one deck.This sine wave web grider 2a comprises upper flange and lower wing plate, and web.Fig. 3 and Fig. 5 can find out, this web is sinusoidal wave web 5a.Because corrugated web provides balanced support strength, so without in web side, support rib being set again.
In Fig. 1, for driving the fork 4 of steel arch-gate motion to be fixed on sinusoidal wave web grider 2a or auxiliary beam 3.
Embodiment 2: the second is made the steel arch-gate of girder of antinode shaped steel, referring to Fig. 6, content is substantially the same manner as Example 1, and something in common does not repeat, different: backwater one side at curved panel 1 is welded with one deck trapezoidal wave web grider 2b, and the web of trapezoidal wave web grider 2b is trapezoidal wave web 5b.
Embodiment 3: the third makes the steel arch-gate of girder of antinode shaped steel, accompanying drawing is not drawn, content is substantially the same manner as Example 1, something in common does not repeat, different: the upper flange of described sinusoidal wave web grider or trapezoidal wave web grider and lower wing plate are linear pattern, or be shaped form, or fold-line-shaped, the parallel distribution of adjacent corrugations web shaped steel or be interspersed or symmetrical.Thereby, the curvature of horizontal, longitudinal and vertical three directions that brace summer has, self support strength is very high, and Area of bearing is larger, thus can reduce brace summer quantity and processing capacity as far as possible.
