Problems solved by technology
The traditional horizontal pull gate adopts a vertical plane structure, and the force is supported on three sides. This structure cannot meet the requirements of ultra-wide gates and high water head conditions. The main reasons are: (1) The vertical plane steel gate structure wants to meet The anti-overturning stability of the structure needs to continuously increase the self-weight of the structure, and increasing the self-weight will not only increase the cost of the gate, but also put forward higher requirements for the gate opening and closing equipment; (2) The section of modern immersed tubes tends to be large, and the design width of the gate It can reach more than 100m, and the force-bearing form of trilateral support cannot play a role

Embodiment Construction
[0028] see figure 1 (The direction of the arrow is the sliding direction when the self-stabilized horizontal tensioned steel gate is opened), figure 2 As shown, a kind of self-stabilized horizontal tensioned steel gate of the present invention; This self-stabilized horizontal tensioned steel gate has a truss main body 1, and this truss main body includes the front bottom beam 2 and the rear bottom beam for connecting and supporting the whole truss main body 3. A plurality of triangular support frames arranged side by side along the length direction of the main body of the truss are erected between the front bottom beam and the rear bottom beam. The triangular support frame described in this embodiment includes a lower chord connecting beam 4 arranged horizontally. The bottom of the braced beam 7 of the beam is connected; the top of the main beam and the top of the braced beam are connected by a top beam 29 arranged along the length direction of the main body of the truss; th...

The invention relates to a self-stabilized type horizontally-pulled steel gate, in particular to a self-stabilized type horizontally-pulled steel gate provided with triangular support frames. The self-stabilized type horizontally-pulled steel gate is provided with a truss body which comprises a front floor beam and a rear floor beam, and a plurality of triangular support frames are erected side by side along the lengthwise direction of the truss body between the front floor beam and the rear floor beam. By the application of the design of the triangular support frames, when water is blocked by the steel gate, water pressure resultant force direction is located under the rear floor beam of the steel gate, and the steel gate itself reaches the anti-toppling stable state. The triangular steel frames are taken as stress units and connected through a supporting pipeline system, so that the steel gate is good in integrality and reasonable in structure stress, self-weight of the steel gate is greatly reduced, requirements on opening and closing force of the steel gate are lowered, and cost of the steel gate is lowered at the same time; overall quality of the self-stabilized type horizontally-pulled steel gate is improved, manufacturing cost is saved, and working efficiency is improved.
Description
technical field [0001] The invention relates to a self-stabilizing horizontally-stayed steel gate, in particular to a self-stabilizing horizontally-stayed steel gate provided with a triangular support frame. Background technique [0002] At present, the horizontal pull gates commonly used in domestic submarine immersed tube prefabrication factories mainly play the role of sealing the gate and retaining water. When the gate is closed, the horizontal pull gate is moved from the gate storage area to the gate area under the traction of the hoisting device and connected to the gate pier. A closed water-stop surface is formed in between for water-retaining work; when the gate is opened, it is pulled laterally by the opening and closing device to the storage area for storage. [0003] In recent years, with the development of large-scale immersed tube factory prefabrication, horizontal pull gates have been widely used in the water retaining structure between the shallow dock and the...
