Embodiment 1

[0027] A bowstring truss type plane gate, comprising a panel 1, four bowstring truss main girders, panel area rib beams for reinforcing the bottom of the four bowstring truss main beams, and four bowstring truss girders for reinforcing the four bowstring truss girders. The main beam reinforcement mechanism at the top of the main beam is used to strengthen the supporting stiffeners at both ends of the bowstring truss type main beam described in the four lines, and the upper ends of the bowstring truss type main beams described in the four lines are fixed in an arrangement of equal intervals or dense at the bottom and sparse at the top The panel 1 is connected, the panel area lattice rib beam is fixedly arranged between the bottoms of the four bowstring truss type main beams, and the main beam reinforcement mechanism is fixedly arranged on the top of the four bowstring truss type main beams, The supporting stiffeners are fixedly arranged at both ends of the four bowstring truss-t...

Embodiment 2

[0046] Such as Figure 7 As shown, this embodiment is basically the same as Embodiment 1, except that this embodiment includes six bowstring truss main girders, forty-eight main girder web members 5, twelve tie rods 7, five horizontal rib beams 8, Thirty-nine vertical rib beams 9; the main girder webs 5 of the bowstring truss type main girder adopt single-slope webs, and the 4 mid-span internodes adopt cable-stayed webs, and the 4 adjacent to the left and right The baroclinic web bars are used for the internodes, and the two internodes at the left and right ends are still fasting web bars. Compared with Embodiment 1, the in-plane rigidity of the gate in this embodiment is greatly improved.

[0047] Further, it includes a single inclined web member 15, the front end of the main beam web member 5 on the left side and the main beam member on the right side among several adjacent main beam web members on the bowstring truss type main girder. The rear ends of the webs 5 are all f...

Embodiment 2

[0050] Such as Figure 8 As shown, this embodiment is basically the same as Embodiment 1 and Embodiment 2, except that this embodiment includes ten bowstring truss main girders, one hundred main girder web members 5, sixteen tie rods 7, nine There are 8 horizontal rib beams and 54 vertical rib beams 9; the main girder web 5 of the bowstring truss type main girder adopts cross-type web members, but the two internodes at the left and right ends are still hollow-type web members . Compared with Embodiment 2, the in-plane stiffness of the gate in this embodiment is further improved.

[0051] Further, including cross-type webs 16, the main beam webs 5 on the left side and the main beam webs 5 on the right side among several adjacent main beam webs on the bowstring truss type main girder A cross-type web bar 16 is fixedly connected therebetween.

[0052] Other parts in this embodiment are the same as Embodiment 1 and Embodiment 2, and will not be repeated here.

Abstract

The invention discloses a bowstring-truss-type plane gate. The bowstring-truss-type plane gate comprises a panel, a plurality of bowstring-truss-type main beams, panel region grid rib beams, main beamstrengthening mechanisms and bearing stiffening ribs; the panel region grid rib beams are used for strengthening the bottoms of the multiple bowstring-truss-type main beams; the main beam strengthening mechanisms are used for strengthening the tops of the multiple bowstring-truss-type main beams; the bearing stiffening ribs are used for strengthening the two ends of the multiple bowstring-truss-type main beams; the upper ends of the multiple bowstring-truss-type main beams are fixedly connected with the panel in a manner of being arranged at equal intervals or being arranged densely at the lower parts and sparsely at the upper parts; the panel region grid rib beams are fixedly arranged among the bottoms of the multiple bowstring-truss-type main beams; the main beam strengthening mechanisms are fixedly arranged at the tops of the multiple bowstring-truss-type main beams; and the bearing stiffening ribs are fixedly arranged at the two ends of the multiple bowstring-truss-type main beams. Bowstring trusses are used as the main beams of the gate, so that the gate has the advantages of large span, small end thickness, handiness, material saving, attractive appearance, stress equilibrium of different components and the like, and the reliability of force transfer between boundary beams and supports is ensured.

Description

technical field [0001] The invention relates to a bowstring truss type plane gate, which belongs to the technical field of water conservancy engineering gates. Background technique [0002] Among the gates, the straight-up planar gate is the most common, and the types of beam systems are mostly solid web and rectangular truss. As the design size and design water head of hydraulic gates are getting larger and larger, solid belly gates show shortcomings such as large steel consumption and large opening and closing force, while rectangular truss gates have unbalanced internal force of components and excessive thickness at the end This has led to shortcomings such as excessive door slot volume. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a bowstring truss type planar gate with light weight, balanced force and small end thickness. [0004] In order to achieve the above o...
