Embodiment Construction

[0031] A large-span reinforced concrete dome structure, which includes a hemispherical reinforced concrete dome with a diameter of about 11 meters. The hemispherical reinforced concrete dome is connected with the surrounding pitched roof and supported on the pitched roof. The reinforced concrete dome is connected with the pitched roof A horizontal ring beam is provided at the location, and a cornice is provided at the top of the reinforced concrete dome.

[0032] A construction method for a large-span reinforced concrete dome structure, the construction process is as follows figure 1 As shown, it includes steps such as BIM model making, dome control line placement, full hall support erection, dome keel installation, formwork assembly, and concrete pouring. The main steps are as follows:

[0033] 1. put dome control line

[0034] Pop up the horizontal projection line of the dome on the concrete floor of the lower floor, including the center point, the horizontal projection li...

Abstract

The invention relates to a wide-span semispherical reinforced concrete dome structure and a construction method thereof. The wide-span semispherical reinforced concrete dome structure comprises a semispherical reinforced concrete dome. The construction method thereof comprises the steps of delivering dome control lines, erecting a full framing, installing keels of the dome, splicing templates andpouring concrete. The steel pipe fastener-type full framing is adopted as a support system of an overall dome roof. The structure is highly safe. The prefabricated templates are adopted and subjectedto bending operation so that high dimensional accuracy is obtained. The templates are formed by splicing of dual-layer curved templates. Seam splicing positions are filled and smeared flat by putty inorder to prevent leakage of slurries and reduce repair cost in the later period.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a large-span hemispherical reinforced concrete dome structure and a construction method thereof. Background technique [0002] In recent years, Western European style and Chinese traditional architectural form have become the trend of domestic architecture. The dome is beautiful in shape, which is a combination of Chinese classical architecture and Western religious architectural style, and is favored by people. [0003] At present, most building materials on the market are strong in compression, but poor in shear, bending, and tension. The dome can convert the upper load into the axial compressive stress of the "arch" without tension, shear, and bending. It can save a lot of building materials, and has the double advantages of beauty and energy saving. [0004] However, due to the curved surface of the dome structure, the traditional method of construction is difficult, the...
