Problems solved by technology
However, the traditional solid section design of the cover beam is heavy, and the cost of special transportation and lifting equipment is high. The box section design of the cover beam inner mold cannot be taken out and reused, which seriously affects the overall prefabricated cover beam. economic performance

Embodiment Construction
[0019] The idea, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present invention.
[0020] Such as figure 1 and combine 2 to Image 6 As shown, the prefabricated high-strength concrete hollow cap beam structure whose internal mold can be taken out includes a cap beam bottom plate 6, a cavity 2 with an opening facing upward, a round hole 1 in the bottom plate, and a cover beam web 5. The cap beam bottom plate 6 is provided with multiple The cavity 2 with the opening facing upwards distributed at intervals, the bottom plate of the cover beam 6 is provided with a plurality of bottom plate round holes 1 distributed at intervals, and the bottom plate round holes 1 communicate with the cavity 2 with the opening upward, so The two ends of the cover beam base plate 6 are provided with a cover beam end solid area 3, and t...

The invention discloses a prefabricated high-strength concrete hollow capping beam structure with a removable internal mold, which comprises a capping beam bottom plate, cavities with upward openings,bottom plate circular holes and capping beam web plates. The capping beam bottom plate is provided with a plurality of cavities with upward openings which are distributed at intervals and with a plurality of bottom plate circular holes which are distributed at intervals, and the bottom plate circular holes are communicated with cavities with upward openings. Capping beam end solid areas are arranged at two end parts of the capping beam bottom plate, and capping beam pier top solid areas are arranged on the capping beam bottom plate. Capping beam web plates are arranged at the front and rear parts of the capping beam bottom plate. The prefabricated high-strength concrete hollow capping beam structure with removable internal mold has the beneficial effects that the capping beam adopts an integral prefabricated assembly structure, so that the influence of construction on the environment is reduced. Compared with the capping beam adopting sectional prefabricated assembly, the capping beamhas better integral performance and better stress performance, reduced weight of about 25-30% compared with the traditional capping beam with a solid section, removable and reusable internal mold, convenience in construction, and larger economic benefits.
Description
technical field [0001] The invention relates to the technical field of prefabricated assembled bridge construction, in particular to a prefabricated high-strength concrete hollow cap beam structure with a removable inner mold. Background technique [0002] At present, the concept of prefabricated and assembled bridges is expanding from the superstructure to the substructure, and is rapidly developing towards fully prefabricated and assembled bridges. The scope of prefabricated components gradually covers girders, piers, abutments, foundations, anti-collision walls, cover beams, etc. The fully prefabricated construction technology has been increasingly adopted in Europe, America, Japan and other countries due to its convenient and fast construction, stable and reliable quality, and low impact on traffic and the environment. Urban viaducts are limited by the section form of ground auxiliary roads, and sometimes it is necessary to use large cantilever prestressed concrete cap ...
