Abstract
The utility model discloses an assembled closure section locks strength nature skeleton outward, it includes double pin steel case roof beam (8), connects transverse connection board (6) at the upper and lower face of double pin steel case roof beam (8), and the both ends head is connected with skeleton end connecting plate (4) about double pin steel case roof beam (8), and skeleton end connecting plate (4) are connected with bracket connecting plate (3), be connected with bracket set -square (1), bracket mother board (2) are connected, are now connected to the side and the bracket connecting plate (3) of bracket set -square (1), connect mother board anchor shaped steel (5) below bracket mother board (2). This final closure locking is for outer lock mode, and is few to closure section construction interference, but the material reutilization, and the working efficiency is high, economically the escapable cost. Especially, be bolt connection between steel case roof beam skeleton end connecting plate and the bracket connecting plate, saved the most microthermal locking time of final closure greatly, assurance closure section's that can be better closure quality and full -bridge one -tenth bridge quality.
Description
Technical field
This utility model is related 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 welding between interior external lock stiff skeleton steel box-girder and bracket, when leading to closure lowest temperature to lock, weld interval is oversize, does not have
Method ensures to realize closure mouth locking in lowest temperature, and closure section closure quality is affected.A large amount of internal lock stiffness bones
Frame is cast in box girder web, causes a large amount of shaped steel unrest expenses, uneconomical on cost.
Utility model content
The technical problems to be solved in the utility model is：There is provided and outside a kind of assembled closure section, lock stiff skeleton, can essence
Guarantee that card realizes locking and system conversion in lowest temperature, can preferably ensure closure quality and the full-bridge Cheng Qiaozhi of closure section
Amount, is cast in box girder web with the skeleton overcoming prior art to exist, and causes a large amount of shaped steel unrest expenses, uneconomical etc. on cost
Not enough.
The technical solution of the utility model is：It includes Two bors d's oeuveres steel box-girder, connects in Two bors d's oeuveres steel box-girder above and below and laterally connects
Fishplate bar, is connected with skeleton termination connecting plate, skeleton termination connecting plate and bracket connecting plate in the left and right two ends of Two bors d's oeuveres steel box-girder
Connect；It is connected with bracket set square, the side of bracket set square is connected with bracket connecting plate, connects bracket motherboard, bracket below
Motherboard anchoring shaped steel is connected below motherboard.
Template anchoring shaped steel adopts 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, connect steel box-girder skeleton termination and connect in lowest temperature in a day
Plate is locked with the connecting bolt realization of bracket connecting plate.
Closure mouth of the present utility model is locked as outer lock mode, few to closure section construction interference, and material can secondary utilize,
Working efficiency is high, economically escapable cost.Company especially between steel box-girder skeleton termination connecting plate and bracket connecting plate
The mode that connects is innovated the locking time greatling save closure mouth lowest temperature for bolt connecting mode by the mode that just connects, and can accurately ensure
Realize locking and system conversion in lowest temperature, can preferably ensure closure quality and the full-bridge quality of finished bridge of closure section
The beneficial effects of the utility model：
1st, closure section stiff skeleton adopts outer lock mode, and using assembled stiff skeleton, closure section construction interference is few, material
Material can achieve secondary utilization, in construction benefit and economically escapable cost.
2nd, can accurately ensure that closure section is realized realizing closure locking in minimum temperature, be conducive to closure section closure quality
With full-bridge quality of finished bridge.
3rd, with bolts realize locking and can reduce substantial amounts of weld interval, skeleton quality is had no effect, can protect
Card closure section realizes closure when being in the longest.

Specific embodiment
Embodiment of the present utility model：It includes Two bors d's oeuveres steel box-girder 8, connects lateral connection in Two bors d's oeuveres steel box-girder 8 above and below
Plate 6, is connected with skeleton termination connecting plate 4 in the left and right two ends of Two bors d's oeuveres steel box-girder 8, and skeleton termination connecting plate 4 is connected with bracket
Plate 3 connects；It is connected with bracket set square 1, the side of bracket set square 1 is connected with bracket connecting plate 3, connects bracket motherboard below
2, bracket motherboard 2 connects motherboard anchoring shaped steel 5 below.
Bracket set square 1, bracket motherboard 2 and motherboard anchoring shaped steel 5 are using being welded to connect.
Two bors d's oeuveres steel box-girder 8, skeleton termination connecting plate 4 and cross connecting plate 6 are using being welded to connect.
Connected using bolt 7 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.
Process bracket motherboard 2 in advance and weld with motherboard anchoring shaped steel 5, a sections is pre-buried on closure mouth and is cast in case
In beam concrete.It is welded bracket set square 1, the bracket connecting plate 3 at two ends before closure bottom temperature, hang in one day minimum temperature
Skeleton termination connecting plate 4 is connected locking closure section simultaneously using connecting bolt 7 by dress assembled stiff skeleton with bracket connecting plate 3
Carry out full-bridge system transform.
After closure section concrete strength reaches design requirement with elastic modelling quantity after full-bridge closure, release connecting bolt 7 and remove dress
Join formula stiff skeleton.
