Abstract
A supporting bracket of a bridge plate jacking device comprises supporting bracket bodies. The supporting bracket bodies which are arranged in row are mounted on two side surfaces of a bent cap at intervals, each supporting bracket body consists of a top plate and a vertical plate which are connected into an inverted L-shaped structure, at least two triangular diagonal bracing plates are connected between the top plate and the vertical plate, the upper side of the top plate of each supporting bracket body faces towards a joint between two adjacent bridge plates, a pitch capable of holding a jack is reserved between the top plate and each bridge plate, bolt holes are distributed on the vertical plate of each supporting bracket body, and the vertical plates are fixed with the side surface of the bent cap via bolts. The supporting bracket is simple in structure and convenient and fast in installation. During usage, the triangular steel plate supporting brackets are directly mounted on two sides of the bent cap and below the bridge plates according to required amount, simultaneous integral jacking of two sides of a bridge span can be realized, the supporting bracket is applicable to jacking construction of the bridge plates, and the height between each bridge plate and the bent cap is smaller than that of the jack.
Description
Technical field
The utility model relates to the bearing support in a kind of bridge board jack-up construction.
Background technology
In the bridge board integral top lifting construction,, normally adopt ultrathin hydraulic jack (existing ultrathin jack is 10cm) for solving the problem of small space bridge board integral jacking.When the height between bridge board and the bent cap during less than the height of jack, jack then can't be placed on and carry out work on the bent cap.
Summary of the invention
The purpose of this utility model provides a kind of bearing support of bridge board lift-up device, in the time of solving height between bridge bridge board and the bent cap less than the height of jack, and the technical problem of bridge board integral jacking.
For achieving the above object, the utility model adopts following technical scheme:
The bearing support of this bridge board lift-up device, comprise the supporting support body, described supporting support body in a row is installed on the two sides of bent cap at interval, described supporting support body is connected the forming structure by top board with riser, and between top board and riser, be connected with at least two triangle tilt props, the top board top of each supporting support body is over against the plate seam of adjacent two bridge boards, leave the spacing that to place jack between top board and the bridge board, be distributed with bolt hole on the riser of supporting support body, riser is fixed by bolt and bent cap side.
Described bolt hole vertically is distributed with three row, at least three of every row on riser.
Compared with prior art the utlity model has following characteristics and beneficial effect:
The utility model is simple in structure, quick and easy for installation.During use on demand quantity directly the triangular steel plate bearing support is installed under bent cap both sides, the bridge board, can realize spanning both sides integral jacking simultaneously.
The utility model is applicable to that in the bridge board jack-up construction, the height between bridge board and the bent cap is less than the situation of the height of jack.

The specific embodiment
Embodiment is referring to shown in Figure 1, the bearing support of this bridge board lift-up device, comprise the supporting support body, described supporting support body in a row is installed on the two sides of bent cap 6 at interval, described supporting support body is connected the forming structure by top board 1 with riser 2, and between top board 1 and riser 2, be connected with at least two triangle tilt props 3, top board 1 top of each supporting support body is over against the plate seam of adjacent two bridge boards 7, leave the spacing that to place jack 8 between top board 1 and the bridge board 7, be distributed with bolt hole 4 on the riser 2 of supporting support body, bolt hole 4 vertically is distributed with three row on riser 2, three of every row.Riser 2 is fixed by bolt 5 and bent cap 6 sides.
The course of work of the present utility model:
The triangular steel plate bearing support is installed in bent cap side under the plate seam of adjacent bridge beam slab, and the triangular steel plate bearing support can adopt the thick steel plate of putting more energy into of 14mm, makes a call to 9 holes in advance on the steel plate, with bolt 5 the triangular steel plate bearing support is fixed on bent cap 6 sidewalls.
