Embodiment Construction

[0012] Such as figure 1 As shown, a fish belly-shaped double-arch structural component of a double-arch gate includes cross-arranged positive arches 1 and reverse arches 2, the cross-closed parts of the double-archs are shuttle-shaped, and the cross-open parts are fishtail-shaped. The two ends of the main arch 1 are connected by chords 3 . The positive arch 1, the reverse arch 2, and the chord 3 are connected through the web 4 perpendicular to the chord 3. The web members are arranged at least at the ends, intersections and middle parts of the double arches.

[0013] Such as figure 2 As shown in Fig. 1, the adjacent double-arch structure components are connected by transverse connecting rods 5, and the transverse connecting rods are arranged near the nodes where the arches and web members intersect, including cross bars connecting corresponding nodes and connecting non-corresponding nodes. Diagonal bar. The steel water-retaining panels 6 are directly welded outside the ch...

Abstract

A gate with double arch structure is prepared as connecting two ends of positive arch by chord; connecting positive arch, negative arch and chord by web member vertical to chord; applying horizontal connection rod to connect adjacent fish belly double-arch components and directly welding steel water-blocking plate at external of chord on each fish belly double-arch component.

Description

technical field [0001] The invention relates to a gate used in water conservancy projects, in particular to a planar gate with double-arch truss structure under bidirectional force, which is suitable for large gate structures with internal and external loads. Background technique [0002] The gates used in water conservancy projects are mainly divided into plane gates and arc gates at present, and what the present invention relates to are plane gates. The planar gate is a plate-shaped door leaf inserted into the door slot to block water. The form of the door leaf can be plate-shaped or shell-shaped, etc. It is opened and closed vertically by the hoist or at the bottom or top of the door leaf. Install traveling rollers to move laterally along the track. The specific structural form of the planar gate is as follows. Its panel is divided into many units of rectangular plates by the beam system. The panel bears all the water pressure, and then the pressure is transmitted to the...
