Embodiment Construction

[0026] Examples see figure 1 As shown, the cast-in-place beam supporting truss is lowered and dismantled as a whole, including four sets of dismantling tools installed on both sides of the upper part of the box girder 9, and the girder body supporting truss 10 is hoisted below the box girder 9 by four sets of dismantling tools.

[0027] Described demolition frock comprises suspender 1, last pad pillow 2, bottom pad pillow 3, shoulder pole beam 4, upper fixing bolt I5, upper fixing bolt II6, lower fixing bolt 7 and two jacks 8. The upper cushion 2 is located on the box girder 9, two jacks 8 are placed on the upper cushion 2, the oil cylinder of the jack 8 tops the shoulder beam 4, and the lower cushion 3 is placed on the bottom surface of the beam support truss 10. The suspender 1 is made of finish-rolled rebar. The upper end of the suspender 1 passes through the reserved hole on the box girder 9, the upper cushion 2 and the pole beam 4 successively. The upper fixing bolt I5 ...

Abstract

The invention provides a cast-in-place beam support truss integral dropping and dismounting tool and a construction method thereof. An integral beam support truss is suspended below a box girder through four dismounting tools. Each dismounting tool comprises a suspender, an upper bolster, a lower bolster, a carrying pole beam, an upper fixing bolt I, an upper fixing bolt II, a lower fixing bolt and two jacks. The integral beam support truss can be synchronously dropped to a height suitable for a crane or can be directly dropped on the ground for dismounting under the conditions that a construction site is narrow, land requisition and demolishing are difficult, the terrain is complex, the construction period is short, the working height is limited and the crane can not be in place, so safety risks caused by hoisting at high altitude are prevented; meanwhile, the dismounting efficiency of the support truss is improved. Through the adoption of the cast-in-place beam support truss integral dropping and dismounting tool and the construction method thereof, it only takes three hours to dismount the beam support truss, the dismounting speed is greatly lowered, the crane cost and labor cost are saved, the construction site is reduced, and the effects of energy conservation, emission reduction and environment protection are achieved.

Description

technical field [0001] The invention relates to a tool for overall lowering and dismantling of a cast-in-place box girder support truss for a passenger dedicated line support and a construction method thereof. Background technique [0002] In the construction of cast-in-place beams for passenger dedicated lines, the removal of cast-in-place beam brackets is a key process and a major factor affecting the construction time of beams. The traditional demolition method is to use manual hoists to drag the beam bottom truss to both sides of the beam body (to meet the hoisting height of the crane), and then hoist and dismantle it with a crane. When it is in place, traditional demolition equipment cannot meet the requirements of construction period and safety. Contents of the invention [0003] The invention provides a cast-in-place beam supporting truss overall lowering demolition tooling and a construction method thereof, and aims to solve the technical problems of low demolitio...
