Abstract
Description
Technical field
the invention belongs to bridge construction technical field of buildings, be specifically related to a kind of 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, but carry out closure section construction above existing railway or highway, will manage canopy protection to existing railway or highway.And the construction of pipe canopy will cause interference to existing railway or highway.The continuous beam of particularly turning, in order to reduce that the interference of existing highway or railway is adopted to rotator construction, but closure section construction is larger on its impact again, like this superiority of rotator construction is produced to certain influence.
Summary of the invention
The object of this invention is to provide a kind of 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 solution adopted in the present invention is:
The continuous beam of turning closure section box hat, 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 stiffening rib longitudinally 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, forms the operation integral body of bottom sealing with two ends housing.
On diaphragm, be reserved with for the prestressed pore passage through prestress pipe.
The present invention has the following advantages:
The employing of the present invention's section of closure box hat 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 reduce closure segment construction to 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 view in transverse section of the present invention.
Fig. 2 is housing of the present invention 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 present invention will be described in detail.
A kind of continuous beam closure section box hat of turning the present invention relates to, 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, as what arrange in Fig. 3, is twice.On diaphragm 3, be reserved with for the prestressed pore passage 5 through prestress pipe.Diaphragm 3 two sides are welded with the stiffening rib longitudinally 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 the operation integral body of bottom sealing with two ends housing 1.
When section 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 the colligation of reinforcing bar, the placement of prestress pipe, and concrete perfusion like this.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 reduce closure segment construction to 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 invention is not limited to embodiment, and the conversion of any equivalence that those of ordinary skills take technical solution of the present invention by reading manual of the present invention, is claim of the present invention and contains.
