Abstract
The invention discloses and lock stiff skeleton outside a kind of assembled closure section, it includes Two bors d's oeuveres steel box-girder (8), cross connecting plate (6) is connected in Two bors d's oeuveres steel box-girder (8) above and below, left and right two ends at Two bors d's oeuveres steel box-girder (8) connects has skeleton termination connecting plate (4), skeleton termination connecting plate (4) to be connected with bracket connecting plate (3)；Being connected with bracket set square (1), the side of bracket set square (1) is connected with bracket connecting plate (3), connects bracket motherboard (2) below, and bracket motherboard (2) connects motherboard anchoring shaped steel (5) below.This closure mouth is locked as outer lock mode, few to closure section construction interference, and material can utilize by secondary, and working efficiency is high, escapable cost economically.It is especially bolt connecting mode between steel box-girder skeleton termination connecting plate and bracket connecting plate, is greatly saved the locking time of closure mouth lowest temperature, can preferably ensure closure quality and the full-bridge quality of finished bridge of closure section.
Description
Technical field
The present invention relates to lock stiff skeleton outside a kind of assembled closure section.
Background technology
Traditional closure section stiff skeleton locking mostly is locking in web, has locked after-pouring in box girder web.Part
All using between interior external lock stiff skeleton steel box-girder and bracket and weld, when causing closure lowest temperature to lock, weld interval is oversize, does not has
Method ensures to realize closure mouth locking when lowest temperature, affects closure section closure quality.A large amount of internal lock stiffness bones
Frame is cast in box girder web, causes a large amount of shaped steel unrest expense, uneconomical on cost.
Summary of the invention
The technical problem to be solved in the present invention is: provides and locks stiff skeleton outside a kind of assembled closure section, can accurately protect
Card realizes locking and converts with system when lowest temperature, can preferably ensure closure quality and the full-bridge quality of finished bridge of closure section, with
The skeleton overcoming prior art to exist is cast in box girder web, causes a large amount of shaped steel unrest expense, uneconomical deficiency such as grade on cost.
The technical scheme is that it includes Two bors d's oeuveres steel box-girder, connect lateral connection in Two bors d's oeuveres steel box-girder above and below
Plate, the left and right two ends at Two bors d's oeuveres steel box-girder connects skeleton termination connecting plate, and skeleton termination connecting plate is with bracket connecting plate even
Connect；Being connected with bracket set square, the side of bracket set square is connected with bracket connecting plate, connects bracket motherboard below, and bracket is female
Motherboard anchoring shaped steel is connected below plate.
Template anchoring shaped steel uses channel-section steel to weld with bracket template, is embedded in a sections design position after processing in advance
Put.
Welding bracket and bracket motherboard before closure locking, connected steel box-girder skeleton termination in one day and connect during lowest temperature
Plate realizes locking with the connecting bolt of bracket connecting plate.
The closure mouth of the present invention is locked as outer lock mode, few to closure section construction interference, and material can utilize by secondary, work
High efficiency, economically escapable cost.The especially connection side between steel box-girder skeleton termination connecting plate and bracket connecting plate
It is bolt connecting mode locking time of being greatly saved closure mouth lowest temperature that formula is innovated by the mode that just connects, and can accurately ensure
Realize locking during low temperature to convert with system, can preferably ensure closure quality and the full-bridge quality of finished bridge of closure section
Beneficial effects of the present invention:
1, closure section stiff skeleton uses outer lock mode, uses assembled stiff skeleton, and closure section construction interference is few, and material can
Realize secondary to utilize, at construction benefit and economically escapable cost.
2, closure section can be ensured accurately to realize when minimum temperature and to realize closure locking, beneficially closure section closure quality
With full-bridge quality of finished bridge.
3, realization locking with bolts can reduce substantial amounts of weld interval, has no effect skeleton quality, can protect
Card closure section realizes closure when being in the longest.

Detailed description of the invention
Embodiments of the invention: it includes Two bors d's oeuveres steel box-girder 8, connect cross connecting plate 6 in Two bors d's oeuveres steel box-girder 8 above and below,
Left and right two ends at Two bors d's oeuveres steel box-girder 8 connects skeleton termination connecting plate 4, and skeleton termination connecting plate 4 is with bracket connecting plate 3 even
Connect；Being connected with bracket set square 1, the side of bracket set square 1 is connected with bracket connecting plate 3, connects bracket motherboard 2, cattle below
Lower limb motherboard 2 connects motherboard anchoring shaped steel 5 below.
Bracket set square 1, bracket motherboard 2 and motherboard anchoring shaped steel 5 use and are welded to connect.
Two bors d's oeuveres steel box-girder 8, skeleton termination connecting plate 4 and cross connecting plate 6 use and are welded to connect.
Bolt 7 is used to connect between bracket connecting plate 3 and skeleton termination connecting plate 4.
Two bors d's oeuveres steel box-girder 8 is processed by I-steel.
Motherboard anchoring shaped steel 5 is processed for channel-section steel.
Processing bracket motherboard 2 in advance and weld with motherboard anchoring shaped steel 5, on closure mouth, a sections is pre-buried and is cast in case
In beam concrete.Weld the bracket set square 1 at two ends, bracket connecting plate 3 before end temperature joining the two sections of a bridge, etc, hung when one day minimum temperature
Dress assembled stiff skeleton, uses connecting bolt 7 skeleton termination connecting plate 4 to be connected locking closure section with bracket connecting plate 3 also
Carry out full-bridge system transform.
After closure section concrete strength and elastic modelling quantity reach design requirement after full-bridge closure, release connecting bolt 7 and also remove dress
Join formula stiff skeleton.
