Description
Technical field
The invention mainly relates to as bridge structure demolition technique field, a kind of more particularly to cross-line continuous beam method for dismounting,
Further relate to the cross-line continuous beam dismounting support of aforementioned cross-line continuous beam method for dismounting.
Background technology
Current bridge application is sorted out, demolition blasting method and machinery can be divided into（Non- explosion）Two big classes of dismounting method
Not, each classification contains various different applications again, there is the respective scope of application.Using blasting procedure, straight more than bridging toughening
The method of abolishing, mechanical hoisting method are connect, but is typically removed using Mechanical Method across the existing circuit bridge that is open to traffic.Mechanical removal method refers to utilization
The forms such as plant equipment is crushed to bridge, split, handling are removed.Removed using crane barge lifting more than water Bridge, land
Floor-engaging frame method is frequently with compared with the dismounting of large-tonnage loop wheel machine bulk.But, there is security protection in existing cross-line continuous beam method for dismounting
The problems such as not in place, supporting construction is unreasonable, hanging device model used is big, have impact on to a certain extent safe construction.
The content of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, there is provided a kind of safety and stability, construction environmental protection
Cross-line continuous beam method for dismounting, correspondingly provide in preceding method it is used it is a kind of easy to operate, rationally utilize mechanics principle
The cross-line continuous beam dismounting support high with efficiency of construction.
To solve above-mentioned technical problem, the present invention is employed the following technical solutions：
A kind of cross-line continuous beam method for dismounting, comprises the following steps：
S1：Set up support：With bridge pier, cross-line road surface as basis is set up, support is set up along bridge pier sidepiece, the beam body of bridge is integrally held
It is loaded on support；
S2：The interim pads of Dun Liang：By in across beam body and bridge pier between space snapped up temporarily with rubber cushion blocks and padded, really
Beam body is protected in cutting process, load is effectively passed to bridge pier；
S3：Laterally slitting：Therefrom across span centre position cut-out beam body, with stress of the bridge pier for padding position as beam body that snap up temporarily
The strong point, from bridge pier direction that place of incision pads position to snapping up temporarily cutting beam body while, self extending stitches position to facing
When snap up and pad the bridge pier direction at position and symmetrically cut beam body successively, the horizontal slitting of beam body is cut into plate beam element, plate-girder list
Unit falls on support；
S4：Piecemeal hangs：The plate beam element of cutting is hung successively to specified location using hanging device；
S5：Removal bracket：After the completion for the treatment of that plate beam element hangs, support is dismantled.
As the further improvement to above-mentioned technical proposal.
The step of setting up support in step S1 is specially：The support member parallel to bridge pier is set up along bridge pier sidepiece, with
To support, distribution beam group and support bracket, the support bracket are set up in the top between the support member of adjacent bridge pier to support member
Top be close to the bottom of beam body.
Concretely comprising the following steps for distribution beam group and support bracket is set up in step S1：Between the support member of adjacent bridge pier
Top set up distribution beam group, distribution beam group top laying support bracket until support bracket at the top of be close to beam body
Bottom, gap carries out snapping up padding using wedge type block between distribution beam group and support bracket.
The concrete steps of distribution beam group and support bracket are set up in step S1 also to be included：In beam body both sides support bracket
Top erection construction occasional passage, construction occasional passage on the outside of safety device is set.
Hanging device is located on the same track on plate beam element place cross-line road surface to be hung in step S4.
Step S5 is concretely comprised the following steps：In same cut direction, after the completion for the treatment of that all plate beam elements hang, to
Hang the support below plate beam element to dismantle by cross from top to down.
Device therefor is cut in step S3 for rope saw.
As a total inventive concept, present invention also offers a kind of cross-line continuous beam used by preceding method is removed using
Support, the support includes support member and anchor ear, and the support member is arranged on the cushion cap of corresponding bridge pier bottom periphery and and bridge
Pier is parallel, and support member is by the anchor ear lock ring in bridge pier sidepiece, and adjacent two support members top is taken equipped with distribution beam group, described
Distribution beam group top is equiped with the support bracket for bearing bridge weight when bridge is removed.
As the further improvement to above-mentioned technical proposal：
Support member positioned at bridge both ends is arranged on the inside portion of corresponding bridge pier, and centrally located support member is arranged on phase
Answer the both sides of bridge pier.
The support also includes connector and diagonal brace, and the two ends of the distribution beam group are fixed on adjacent by the connector
Two support members top, described diagonal brace one end is affixed with support member waist, and the other end is affixed with the bottom on distribution beam group side edge.
The distribution beam group includes plural longitudinal stake top distribution beam, Bailey beam and horizontal little distribution beam, the shellfish
Lei Liang is fixed between longitudinal stake top distribution beam and the horizontal little distribution beam, and the middle part of longitudinal stake top distribution beam leads to
The top that the connector is fixed on the support member is crossed, the bottom on the side edge of longitudinal stake top distribution beam passes through the diagonal brace
One end be fixed on the support member waist, the Bailey beam is welded in the top of longitudinal stake top distribution beam, described to hold
Weight support is installed on the top of horizontal little distribution beam.
The support bracket is full hall scaffold.
The support member is connected on the cushion cap by reinforcing bar and Interal fixation.
The support member is steel column.
Compared with prior art, it is an advantage of the current invention that：
