Combined prefabricated arched baseplate and superposed arched plates

Abstract

The invention discloses a combined prefabricated arched baseplate and a superposed arched plate, relates to the field of architectural structures, and solves the problem that cast-in-place casting ofan existing arched plate needs template construction which is complex and high in difficulty and cost. The technical scheme includes that the combined prefabricated arched baseplate comprises a prefabricated arched baseplate and a support piece, connection pieces are embedded in the prefabricated arched baseplate, upper ends of the connection pieces penetrates through an outer side of the prefabricated arched baseplate, and the support piece is positioned on an inner side or an outer side of the prefabricated arched baseplate and is detachably connected with the upper ends or lower ends of theconnection pieces. A concrete superposition layer is poured after the outer side of the prefabricated arched baseplate is poured, so that the superposed arched plate is formed. The combined prefabricated arched baseplate and the superposed arched plate have the advantages that template-free construction can be realized, engineering quantity can be decreased, difficulty can be lowered, construction period can be shortened, cost can be saved, construction quality, especially appearance quality can be benefited, the prefabricated arched baseplate can be thinner, bending resistance of the prefabricated arched baseplate in a construction process can be adjusted, plate types can be reduced, and improvement of fabricated construction can be facilitated.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a combined prefabricated arched base plate and a superimposed arched plate of an assembled building. Background technique [0002] The existing arched slabs are poured on-site and formwork needs to be erected in advance. The superimposed arched slab is often located on the top of the building, and its position is relatively high, and it is curved. On-site pouring requires a large number of support frames, which has the disadvantages of cumbersome construction, high difficulty, and high cost. Moreover, since the formwork is formed by splicing, the arched plates at the joints are not smooth and need to be processed later; moreover, the formwork itself is easily deformed, and the whole formwork is also easily deformed after splicing, resulting in deformation of the shape of the arched plate, especially the arch The shape of the inner side of the shape plate is not stand...
