Construction method of a prefabricated assembly cornice

Abstract

The invention discloses a construction method for a prefabricated cornice. The construction method specifically comprises the following steps of making preparations before construction; pre-burying main structural iron pieces; fabricating cornice components; constructing an operating platform; welding and mounting the cornice; specifically, prefabricating of the cornice components includes the steps of determining the sizes of components with different specifications according to prepared models, determining the sizes of the pre-buried iron pieces in the components at the same time, and determining the length and the welding sizes of internal pre-buried bars; preparing the corresponding pre-buried iron pieces according to the sizes of the pre-buried iron pieces; manufacturing mounting formworks and brushing a mold releasing agent; mounting the pre-buried bars and the corresponding pre-buried iron pieces in the mounting formworks; pouring ceramsite concrete and conducting vibration; using an iron trowel to conduct trowelling and surface finishing to ensure the surface achieve hydrophile effect; conducting demoulding after maintenance and conducting numbering; and conducting stacking according to the corresponding specifications.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for a prefabricated cornice. Background technique [0002] With the development of the times and economy, the shape of buildings is becoming more and more complex. For example, a large number of Chinese wind elements are also applied in concrete structural engineering. Antique buildings refer to buildings specially used to imitate and replace ancient buildings, traditional religious temples, traditional landscaping, historical buildings, cultural relics buildings, ancient village groups, and restore the general situation of historical features. Dougong, also known as Pazuo, is the essence of traditional Chinese ancient buildings and one of the important symbols showing the level of buildings. At the junction of columns and beams, the bow-shaped frame structure protruding from the top of the column is called gong, the square pad between gong and gong is...

Problems solved by technology

[0003] The traditional construction method of the antique building is to use the cast-in-place method for construction. The antique building formed by the construction is a cast-in-place concrete structure. The complex components of the cornice are also made of concrete structure and are simultaneously cast-in-place with the main structure. There are complex construction techniques, Defects and deficiencies such as long construction period, low construction efficiency, many safety control items, and difficult construction quality control
