Stacked arch shell structure and construction method thereof

Abstract

The invention discloses a stacked arch shell structure and a construction method thereof, and relates to the building engineering construction technology field. The stacked arch shell structure comprises a prefabricated part and cast-in-place parts, wherein the cast-in-place parts are arranged on the upper surface of the prefabricated part, the prefabricated part and the cast-in-place parts are all in an arch shape, the prefabricated part comprises a plurality of prefabricated arch shell elements distributed in the direction perpendicular to the span direction of the prefabricated part, a gapbetween each two adjacent prefabricated arch shell elements forms an arch shell interelement seam, a boundary between each two adjacent cast-in-place parts forms a cast-in-place part seam, and each cast-in-place part seam is located between each two adjacent arch shell interelement seams in the plane. For solving the problem that no method is applicable to an arch shell structure in the prior art,the stacked arch shell structure adopts a stacked structure of arch reinforced concrete, is applicable to arch structure and bridge construction, and has the advantages of being high in constructionspeed and high in structure accuracy.

Description

technical field [0001] The invention relates to the technical field of building engineering construction, more specifically, it relates to a superimposed arch shell structure and a construction method thereof. Background technique [0002] In the construction of reinforced concrete projects, the superimposed structure has been widely used due to its advantages of fast construction speed and high structural precision. [0003] Existing laminated structures include laminated beams and laminated slabs, etc., laminated slabs such as figure 1 shown. exist figure 1 Among them, the laminated slab is composed of a prefabricated part 1 and a cast-in-place part 2, the prefabricated part 1 is in the lower part of the laminated structure, and the cast-in-place part 2 is in the upper part of the laminated structure. During construction, the prefabricated part 1 is first installed in place by the assembly method, and then steel bars are bound and concrete is poured above the prefabrica...
