Fabricated longspan concrete double-slope net shell roof framework and manufacturing method thereof

Abstract

The invention discloses a fabricated longspan concrete double-slope net shell roof framework and a manufacturing method thereof. The framework is formed by obliquely placed multi-ribbed slabs converged at a ridge beam, the two ends are supported on gable end partitions, slope bases supported on longitudinal frame beams vertically intersected with anti-pushing frameworks, and no supporting frame isinstalled under the ridge beam. The gable end partitions are triangle vierendeel trusses composed of upper chords, lower chords and vertical web members, the anti-pushing frameworks are composed of framework columns and short-leg shears supported under lower part floor beams. The framework manufacture adopts a fabricated method, roof boards and ribs are prefabricated and all-round scaffolds, prefabricated parts are connected into an entirety through cast-in-place of connecting blocks and pouring of the boards and the ribs connecting concrete, the use ratio of the large space under the roof isimproved, the problem of flowing during the cast-in-place of obliquely placed concrete in a large area is overcame, the template consumption is reduced, and the construction period is shortened.

Description

technical field [0001] The invention belongs to the technical field of architectural concrete structures, and in particular relates to a structural type of a prefabricated large-span double-slope roof built with reinforced concrete materials in a frame structure and a manufacturing method thereof. Background technique [0002] The sloping roof is a typical symbol of traditional architecture in my country, and it is widely used in modern concrete public and residential buildings. The sloping roof not only has the advantages of good drainage, anti-seepage and anti-leakage, but also can enrich the building facade, improve the utilization rate of the top floor space, and improve the living environment on the top floor. [0003] The common structural type of the current double-slope roof is the ordinary beam-slab structure, that is, in addition to the support around the roof, it is necessary to set up masonry walls or frame beams under the roof ridge to support the roof ridge, wh...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide an assembled large-span concrete double-slope reticulated shell structure for the double-slope roof of public and residential buildings. Compared with the existing ordinary beam-slab double-slope roof, it has better space The mechanical performance can reduce the amount of materials; because there is no supporting structure under the roof ridge, a large space on the top floor can be formed, which improves the space utilization rate of the top floor of the building; the consumption of formwork is reduced due to the assembly of prefabricated components, and the construction period is shortened. , reducing the difficulty of pouring concrete
