Abstract

The invention discloses a combined prefabricated arched bottom plate and superimposed arched slab, relates to the field of building structures, and solves the problems that existing arched slabs are poured and formed on-site, formwork needs to be erected, construction is cumbersome, difficult and expensive. The technical solution adopted in the present invention is: combined prefabricated arched floor, including prefabricated arched floor and supporting parts, connecting pieces are embedded in the prefabricated arched The inner side or the outer side of the arched bottom plate, and the supporting part is detachably connected to the upper end or the lower end of the connecting part. The outer side of the prefabricated arched bottom slab is poured and the composite layer of concrete is poured to form a composite arched slab. The invention can realize form-free construction, reduce engineering quantity, reduce difficulty, shorten construction period, save cost, and help to ensure engineering quality, especially appearance quality. The prefabricated arched bottom plate can be made thinner, and its bending resistance during the construction stage can be adjusted to reduce types and promote the development of prefabricated buildings.

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...

Examples

Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing.

[0030] The combined prefabricated arched bottom plate of the present invention includes a prefabricated arched bottom plate 1 and a support member 2, and the prefabricated arched bottom plate 1 is equipped with reinforcement, that is, the prefabricated arched bottom plate 1 is provided with a reinforcement mesh. The prefabricated arched bottom slab 1 is a reinforced concrete slab or a prestressed reinforced concrete slab. Connectors are also buried in the prefabricated arched floor 1, the upper end of the connectors passes through the outer side of the prefabricated arched floor 1, and the part passing through the outer side of the prefabricated arched floor 1 forms a shear stud, which realizes the prefabricated arch. The new concrete on the outer side of the arched base plate 1 and the prefabricated arched base plate 1, that is, the shear connection with the laminated laye...
