Abstract
The utility model relates to a rotation continuous beam closure segment steel shell. The closure segment construction of rotation construction greatly influences lower existing lines. The rotation continuous beam closure segment steel shell is provided with a shell body completely identical to the shape of the outer surface of a beam body, the shell body is connected to the end of the beam body of a rotation continuous beam, and the shell body comprises a base plate and side plates which are arranged on the two sides of the base plate and stretch out upwards. A transverse separating plate which is perpendicular to the baste plate and the side plates of the shell body is welded to the inner wall of the shell body, and the transverse separating plate is a bent strip plate. Longitudinal reinforcing ribs perpendicular to the transverse separating plate are welded to the two faces of the transverse separating plate. A connecting steel plate is welded between the shell bodies at the ends of the beam bodies of two linkage rotation continuous beams to be closed, the connecting steel plate is a bent plate with the shape identical to the shape of the shell body, and the connecting steel plate and the shell bodies at the two ends of the connecting steel plate form a lower sealed operation whole. The closure segment steel shell is used as an outer mould and bears the self-weight of the beam segment and construction loads, the closure segment steel shell and concrete form a connecting beam to participate in structure stress, meanwhile, the closure segment construction is carried out in a completely-sealed steel box, and the influence of the closure segment construction on the existing lines is greatly reduced.
Description
Technical field
the utility model belongs to bridge construction technical field of buildings, is specifically related to the one continuous beam closure section box hat of turning.
Background technology
Continuous beam closure section construction all adopts closure suspension bracket as carrier at present, on closure suspension bracket, carries out after formwork, continuous beam being joined the two sections of a bridge, etc, and will carry out the protection of pipe canopy to existing railway or highway but carry out closure section construction above existing railway or highway.And the construction of pipe canopy will cause interference to existing railway or highway.The continuous beam of particularly turning, adopt rotator construction, but closure section construction is larger on its impact again in order to reduce the interference to existing highway or railway, like this superiority of rotator construction is produced to certain influence.
Summary of the invention
The purpose of this utility model is to provide the one continuous beam closure section box hat of turning, while reducing to turn continuous beam closure section construction to the existing highway under it or the Influence to operation of railway.
The technical scheme that the utility model adopts is:
The one continuous beam closure section box hat of turning, is characterized in that:
Be provided with and the identical housing of beam external surface shape, be connected to the end of the beam body of the continuous beam of turning, housing comprises the side plate that base plate and base plate both sides protrude upward;
Inner walls is welded with the diaphragm perpendicular to housing base plate and side plate, and diaphragm is the strip plate of bending; Diaphragm two sides is welded with the longitudinal stiffening rib perpendicular to diaphragm.
Two of wish closure is turned and is welded with junction steel plate between the housing of continuous beam beam end of body, and junction steel plate is the bending plate that shape is identical with hull shape, the operation entirety of sealing with two ends housing composition bottom.
On diaphragm, be reserved with for the prestressed pore passage through prestress pipe.
The utlity model has following advantage:
The box hat employing of the utility model closure section and the on all four high strength box hat of beam body profile are as external mold and bear the deadweight of beam section and working load, stressed with concrete formation bondbeam participation structure, make closure section construction carry out in complete totally enclosed steel case simultaneously, greatly reducing closure segment constructs on both wired impact, significantly improve the safety and reliability of spanning existing railway bridge construction, more demonstrated the superiority of rotator construction.
Accompanying drawing explanation
Fig. 1 is the utility model view in transverse section.
Fig. 2 is the utility model housing and stiffening rib combination assumption diagram.
Fig. 3 is the horizontal elevation that two beam-ends closures connect.
In figure, 1-housing, 2-stiffening rib, 3-diaphragm, 4-beam body, 5-prestressed pore passage, 6-junction steel plate.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is described in detail.
The one that the utility model the relates to continuous beam closure section box hat of turning, be provided with and the identical housing 1 of beam external surface shape, be connected to the end of the beam body 4 of the continuous beam of turning, referring to Fig. 1 and Fig. 2, housing 1 comprises the side plate that base plate and base plate both sides protrude upward, and end is also identical with beam body wing plate shape.Longitudinal width of housing 1 can adjust according to the needs of working space size.Housing 1 inwall is welded with the diaphragm 3 perpendicular to housing 1 base plate and side plate, and diaphragm 3 is the strip plate of bending.The quantity of diaphragm 3 can adjust according to longitudinal width of housing 1, is twice as what arrange in Fig. 3.On diaphragm 3, be reserved with for the prestressed pore passage 5 through prestress pipe.Diaphragm 3 two sides are welded with the longitudinal stiffening rib 2 perpendicular to diaphragm 3.Referring to Fig. 3, two of wish closure is turned and is welded with junction steel plate 6 between the housing 1 of continuous beam beam body 4 ends, and junction steel plate 6 is bending plates that shape is identical with housing 1 shape, forms with two ends housing 1 the operation entirety that bottom is sealed.
When section in construction closure,, housing 1 is closely adhered to the end of adjacent two beam sections, after continuous beam is turned and put in place, adopt the junction steel plate 6 of identical appearance that two housings 1 are connected, may in the space of sealing, carry out like this colligation of reinforcing bar, the placement of prestress pipe, and concrete perfusion.The box hat employing of closure section and the on all four high strength box hat of beam body profile are as external mold and bear the deadweight of beam section and working load, stressed with concrete formation bondbeam participation structure, make closure section construction carry out in complete totally enclosed steel case simultaneously, greatly reducing closure segment constructs on both wired impact, significantly improve the safety and reliability of spanning existing railway bridge construction, more demonstrated the superiority of rotator construction.
It is cited that content of the present utility model is not limited to embodiment, and the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model manual, is claim of the present utility model and contains.
