Panel area lattice girt strip described in fish belly truss-like Stoplog gate includes that the vertical panel district lattice girt strip in cambered surface orthogonal beams members lattice system and level are to panel area lattice girt strip.
Tie-rod described in fish belly truss-like Stoplog gate, vertical panel district lattice girt strip and single bevel web member are along the span direction spaced set of Stoplog gate；Level to panel area lattice girt strip along Stoplog gate short transverse spaced set.
Curved panel directly bears hydraulic pressure, the panel area lattice girt strip and the lenticular truss that are arranged on curved panel inner arc side are close together with curved panel, pricncipal rafter, panel area lattice girt strip all use the section form being prone to be directly connected to panel, such as rectangular tube, square tube, channel-section steel, I-steel, angle steel, T-steel etc., it is used for bearing the hydraulic pressure on curved panel.
Preferably, steel flanged beam H type side bar is provided with support ribbed stiffener at the correspondence position being connected with top-bottom chord.
This utility model uses steel flanged beam H type side bar to be prone to carry out assembly with chord member and welds, and beneficially Stoplog gate sliding in gate slot.
In this utility model, the upper lower edge arch camber of lenticular truss is in opposite direction and non-intersect, and top-bottom chord is to achieve tension and compression self-balancing by the Shear transfer of single bevel web member and steel flanged beam H type side bar.On the premise of span is fixing, its bearing capacity can be changed by the spaning middle section height and end cross-sectional height that change lenticular truss top-bottom chord.
The above single bevel web member also can use herringbone fashion or other web member forms such as K formula or staggered form.
This utility model is under high water head operating mode, and Stoplog gate top hydraulic pressure is less, ought to be under the restrictive condition of equal thickness at upper and lower stoplog, it is possible to increase the deck-molding of top single-unit stoplog improves its load-bearing area, gives full play to its bearing capacity.
The beneficial effects of the utility model are:
This utility model uses lenticular truss as girder, reasonable stress, and span is big, and rigidity is big, and bearing capacity is high, from heavy and light, good looking appearance；Use steel flanged beam H type side bar, it is easy to assembled welding, can realize going straight up to open and close；On the premise of span is fixing, stoplog can change its bearing capacity by the spaning middle section height and end cross-sectional height changing lenticular truss top-bottom chord, or changes its load by changing stoplog deck-molding, has stronger motility and adaptability.

Detailed description of the invention
As described in Figure, a kind of fish belly truss-like Stoplog gate include curved panel 1, vertical panel district lattice girt strip 2, level to panel area lattice girt strip 3, steel flanged beam H type side bar 4, wind up 5, lower edge 6, vertical web rod 7, diagonal web member 8, tie-rod 9 and support the technical characteristics such as ribbed stiffener 10.
Fig. 1-3 show a kind of fish belly truss-like stoplog, and multiple fish belly truss-like stoplog superpositions arrange and form a kind of fish belly truss-like Stoplog gate, and a single fish belly truss-like stoplog, the many lenticular trusses of two more than Pin arranged in parallel can be included.
A kind of fish belly truss-like Stoplog gate, stoplog door shield one side is to ship lock, another side is to lock chamber, ship lock side is provided with the curved panel directly bearing hydraulic pressure, it is arranged on the fish belly truss-like stoplog of curved panel inner arc side, being arranged on the steel flanged beam H type side bar of the stoplog left and right sides, the right boundary of curved panel welds with the web of steel flanged beam H type side bar.Lenticular truss wind up and lower edge arch camber is in opposite direction, upper and lower chord member is non-intersect, and upper and lower string arch is ellipse or parabola or variable curvature curve.Upper and lower chord member end is welded with the web of steel flanged beam H type side bar, uses single bevel web member to connect between upper and lower string.
Panel area lattice girt strip is cambered surface orthogonal beams members lattice system, including vertical panel district lattice girt strip and level to panel area lattice girt strip.
Single bevel web member includes vertical web rod and diagonal web member, and the use of diagonal web member can be effectively improved rigidity and the stability of gate.
Pricncipal rafter, panel area lattice girt strip all use rectangular tube, directly and curved panel is affixed.Adjacent two Pin lenticular trusses are connected at lower-chord panel point by tie-rod.Tie-rod, vertical panel district lattice girt strip, vertical web rod are equally spaced along stoplog span direction, and level is equally spaced along stoplog short transverse to panel area lattice girt strip.
As illustrated in figures 4-5, steel flanged beam H type side bar is being provided with orthogonal support ribbed stiffener with the correspondence position that upper and lower chord member is connected, and improves shear resistance and the local bearing capacity of side bar web.
Under high water head operating mode, Stoplog gate top hydraulic pressure is less, ought to improve its load-bearing area by the deck-molding increasing top single-unit stoplog, give full play to its bearing capacity under the restrictive condition of equal thickness at upper and lower stoplog.
