Abstract
The utility model is related to a kind of big section assemblings of bridge with to spelling formula adjustable wedge block, which is mounted between bridge subsection and buttress；It is characterized in that：Including upper voussoir and lower wedge block；The upper voussoir identical as hyposphene block structure is in three-legged structure, is connected at least through one group of feed screw nut pair between upper voussoir and lower wedge block；By being used between the big segment of bridge and buttress to the adjusting wedge for spelling formula instead of original using the pad mode for piling up steel plate layer by layer in the utility model, by the adjusting of feed screw nut pair come so that being produced relative sliding to the adjusting wedge of spelling, make degree of regulation higher, regulative mode more flexible.
Description
Technical field
The utility model is related to bridge construction fields more particularly to a kind of big section assembling of bridge with to spelling the adjustable wedge of formula
Block.
Background technology
The big segment of traditional bridge is in assembly, the pad mode for piling up steel plate layer by layer that moulding bed buttress pad uses, because
Pad steel plate has thickness, when pad needs to continue pad a few tenths of a mm to the end, does not correspond to the steel plate of thickness, so this
Kind of pad mode there are pad height accuracies not high, the imprecise disadvantage of pad is higher to spelling adjustable wedge block pad height accuracy
And pad is tight, and high precision regulating effect is realized by the variation of upper and lower two pads block relative position.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of big section assemblings of bridge with to spelling formula adjustable wedge block, energy
Enough solve the problems, such as that the general height for leading to last several millimeters of the big segment of bridge by the way of pad can not be adjusted.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of big section assembling of bridge is with to spelling formula
Adjustable wedge block, the voussoir are mounted between bridge subsection and buttress；Its innovative point is：Including upper voussoir and lower wedge block；It is described
Upper voussoir identical as hyposphene block structure is in three-legged structure, at least through one group of feed screw nut pair phase between upper voussoir and lower wedge block
Even；
The upper voussoir or lower wedge block include the first L-square, the second L-square and skewback；The inclined-plane of the upper voussoir
It is close to mutually between plate and the skewback of lower wedge block；
One end and one end of the second L-square of first L-square are vertically connected, and the both ends of skewback are respectively with first
The other end of the L-square other end and the second L-square is connected；Vertically up to being provided with one less on first L-square
Accommodate the first waist type groove that lead screw passes through in feed screw nut pair；It is accommodated in feed screw nut pair at least provided with one on the skewback
The second waist type groove that lead screw passes through；
The lead screw of the feed screw nut pair extends through the first waist type groove of the first L-square of voussoir, upper voussoir it is oblique
Second waist type groove of panel, the second waist type groove of the skewback of lower wedge block, the first waist type groove of the first L-square of lower wedge block；Institute
The nut for stating feed screw nut pair has a pair of and is tightly attached to the lead screw for being connected to feed screw nut pair on the outside of the first L-square respectively
On.
Further, lead screw in a pair of of receiving feed screw nut pair is vertically provided on first L-square to pass through
The first waist type groove.
Further, the second waist type groove that lead screw passes through in a pair of of receiving feed screw nut pair is provided on the skewback.
The utility model has the advantage of：
1）By being used to the adjusting wedge for spelling formula instead of original between the big segment of bridge and buttress in the utility model
The pad mode for piling up steel plate layer by layer is used, passes through the adjusting of feed screw nut pair come so that being generated to the adjusting wedge of spelling relatively sliding
It is dynamic so that degree of regulation higher, regulative mode are more flexible.
