Detailed Description
As shown in fig. 1-4, the utility model discloses a concrete embodiment, a rigid hollow slab beam who does not have vertical wet seam, including prefabricated hollow slab beam 1, the top of prefabricated hollow slab beam 1 is provided with cast-in-place roof 2, and the top of cast-in-place roof 2 is provided with asphalt pavement 3.
As the preferable scheme of the scheme, the plate beams are rigidly connected through arranging the integral cast-in-place top plate and arranging the structural stressed steel bars in the cast-in-place top plate, so that the plate beams are stressed integrally. The cast-in-place roof 2 participates in the longitudinal stress to reduce the load shared by the prefabricated hollow slab beam 1, correspondingly, the size of the prefabricated hollow slab beam can be reduced, the hoisting weight during construction is reduced, and the construction difficulty is reduced.
Please refer to fig. 1, the number of the prefabricated hollow plate beams 1 is multiple groups (the number of the prefabricated hollow plate beams 1 is determined according to the width of the road surface), the prefabricated hollow plate beams 1 are formed by combining concrete and structural stressed steel bars, and cast-in-situ top plates 2 are integrally cast on site, so that rigid connection between the prefabricated hollow plate beams is realized, the transverse connection between the prefabricated hollow plate beams 1 is ensured, and longitudinal stress is also participated in.
Please refer to fig. 3 and 4, the prefabricated hollow slab beam 1 has connecting steel bars reserved on the top surface, and after the on-site erection is completed, the cast-in-situ top slab 2 is cast on the site, and no longitudinal wet joint exists on the site. The cast-in-place roof 2 is internally provided with structural stressed steel bars which are mainly transversely arranged.
Please refer to fig. 2, the asphalt pavement 3 is paved on the cast-in-place roof 2, and the asphalt pavement is paved on the cast-in-place roof 2, so as to prevent the cast-in-place roof 2 from being exposed directly, and the bridge body driving is safer, more comfortable and more beautiful.
By adopting the structure, in the using process, the prefabricated hollow slab beam 1 is firstly hoisted and placed on a pier or an abutment, and then the structural stressed steel bars and the poured concrete are bound on the top surface of the prefabricated hollow slab beam 1, so that no longitudinal wet joint exists on site.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
