Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a method for integral casting of concrete roof trusses and construction of concrete eaves in antique-style buildings. Background Technology

[0002] Antique-style buildings refer to buildings specifically designed to imitate and replace ancient buildings, traditional religious temples and monasteries, traditional landscaping, historical buildings, cultural relics buildings, and ancient village clusters, restoring the general appearance of historical sites.

[0003] The existing announcement number CN113738029A discloses a construction method for installing concrete eaves and roof components of an antique building, and announcement number CN106284640A discloses a construction process for cast-in-place concrete brackets of an antique building. These methods improve and optimize the traditional construction of antique buildings, and innovate and improve the installation process between the eaves and the concrete roof frame.

[0004] In actual construction, the installation of concrete eaves and the concrete roof truss as a whole requires concrete pouring. The relatively light concrete eaves are easily impacted during installation, causing positional displacement and affecting the construction quality. Usually, bolts are used to fix them, but this method is cumbersome, and sometimes adjusting the position of the concrete eaves requires repeated fixing, which can damage the concrete roof truss and even waste materials, making it environmentally unfriendly. On the other hand, it cannot be flexibly positioned according to the needs of on-site construction, resulting in low construction flexibility and poor positioning stability, which affects the economic benefits of construction.

[0005] Therefore, this invention proposes a method for integral casting of concrete roof trusses and construction of concrete eaves in antique-style buildings to solve the above problems. Summary of the Invention
