Abstract

The utility model discloses a cast-in-place beam supporting truss overall-falling dismantling tool which comprises four sets of dismantling tools installed on the two sides of the upper portion of a box beam. A whole beam supporting truss is hung below the box beam through the four sets of dismantling tools. Each dismantling tool comprises a suspension rod, an upper bolster, a lower bolster, a shoulder pole beam, an upper fixing bolt I, an upper fixing bolt II, a lower fixing bolt and two jacks. According to the cast-in-place beam supporting truss overall-falling dismantling tool, under the situations that a construction site is narrow, land requisition and demolishing are difficult, the terrain is complex, the construction period is short, the working altitude is limited, and a crane cannot be in place, the whole supporting bottom truss can fall synchronously, the whole supporting bottom truss is dismantled when reaching the height suitable for crane working or directly falling to the ground, safety risks caused by high-altitude hoisting are avoided, and supporting truss dismantling efficiency is improved at the same time. Only three hours are needed when the cast-in-place beam supporting truss overall-falling dismantling tool is used for dismantling a hole beam supporting truss, the die dismantling speed is greatly reduced, the crane cost and the labor cost are saved, construction lands are reduced, and the effects of energy conservation, emission reduction and environmental protection are achieved.

Description

Frock is removed in the landing of Cast-in-situ Beam sub-truss entirety

Technical field

The utility model relates to the landing of a kind of Line for Passenger Transportation support cast-in-place case beam sub-truss entirety and removes frock.

Background technology

In the construction of Line for Passenger Transportation Cast-in-situ Beam, it is critical process that Cast-in-situ Beam support is removed, and is also the principal element that affects the beam body construction time.Traditional dismounting mode is to adopt bottle gouard moved by hands that beam bottom boom frame is drawn to beam body both sides (meeting crane lifting height), then remove with crane lifting, but in narrow, with a varied topography, the duration is tight, operation height is limited, crane can not be in place situation, adopt traditional dismounting equipment can not meet duration and safe requirement on construction ground.

Utility model content

The utility model provides the landing of a kind of Cast-in-situ Beam sub-truss entirety to remove frock, solve tradition dismounting equipment Removal efficiency low, has the technical problem of larger potential safety hazard.

The utility model solves the technical scheme that its technical problem adopts:

Frock is removed in the landing of this Cast-in-situ Beam sub-truss entirety, comprises that quadruplet is installed on the dismounting frock of both sides, case beam top, and beam body sub-truss entirety is removed frock by quadruplet and hung in case beam below;

Described dismounting frock comprises suspension rod, upper bolster, lower bolster, shoulder pole girder, upper set bolt I, upper set bolt II, lower set bolt and two jack; Described upper bolster is seated on case beam, and two jack are placed on bolster, top shoulder pole girder on the oil cylinder of jack, and lower bolster is placed in beam body sub-truss bottom surface; Described suspension rod upper end is successively through preformed hole, upper bolster and shoulder pole girder on case beam, upper set bolt I is in shoulder pole girder end face and suspension rod locking, upper set bolt II is in upper bolster end face and suspension rod locking, suspension rod lower end is through beam body sub-truss and lower bolster, and lower set bolt is in lower bolster bottom surface and suspension rod locking.

Described suspension rod is fining twisted steel.

The bottom surface of fixed bolt I and upper set bolt II is equipped with backing plate, and the end face of lower set bolt is provided with backing plate.

The beneficial effects of the utility model are as follows:

The utility model is fixed on support base truss on the shoulder pole girder of jack through beam body preformed hole with four fining twisted steels, first remove the steel pipe post below sub-truss, then sub-truss is adopted to the landing of jack Integral synchronous, until it is dismountable to drop to ground.

The utility model on construction ground narrow, expropriation of land is removed in the situation difficult, with a varied topography, the duration is tight, operation height is limited, crane can not be in place, whole sub-truss is synchronously landed, reach and be applicable to the height of loop wheel machine operation or directly fall to ground removing, the security risk of having avoided upper air installing to bring, has improved sub-truss simultaneously and has removed efficiency.The utility model is removed a hole beam sub-truss and is only needed 3 hours, has greatly shortened form removal speed, and saves crane and labour cost, has reduced construction land tenure, reaches the effect of energy-saving and emission-reduction, environmental protection.

Reference numeral: set bolt, 8-jack, 9-case beam, 10-beam body sub-truss under bolster, 4-shoulder pole girder, the upper set bolt I of 5-, the upper set bolt II of 6-, 7-under 1-suspension rod, the upper bolster of 2-, 3-.

The specific embodiment

Embodiment is shown in Figure 1, and frock is removed in the landing of this Cast-in-situ Beam sub-truss entirety, comprises that quadruplet is installed on the dismounting frock of case beam 9 both sides, top, and beam body sub-truss 10 entirety are removed frock by quadruplet and hung in case beam 9 belows.

Described dismounting frock comprises suspension rod 1, upper bolster 2, lower bolster 3, shoulder pole girder 4, upper set bolt I5, upper set bolt II6, lower set bolt 7 and two jack 8.Upper bolster 2 is seated on case beam 9, and two jack 8 are placed on bolster 2, top shoulder pole girder 4 on the oil cylinder of jack 8, and lower bolster 3 is placed in beam body sub-truss 10 bottom surfaces.Described suspension rod 1 adopts fining twisted steel.Suspension rod 1 upper end is successively through preformed hole, upper bolster 2 and shoulder pole girder 4 on case beam 9.Upper set bolt I5 locks at shoulder pole girder 4 end faces and suspension rod 1, and upper set bolt II6 locks at upper bolster 2 end faces and suspension rod 1.The bottom surface of fixed bolt I5 and upper set bolt II6 is equipped with backing plate.Suspension rod 1 lower end is through beam body sub-truss 10 and lower bolster 3.Lower set bolt 7 is locked in lower bolster 3 bottom surfaces and suspension rod 1.The end face of lower set bolt 7 is provided with backing plate.
