TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to an arc-shaped curved surface fair-faced concrete ribbed wood formwork and a manufacturing method thereof. BACKGROUND

[0002] In recent years, fair-faced concrete buildings are increasingly popular in the industry market. Fair-faced concrete structures are formed in one step and do not require decoration, and the forming quality thereof is closely related to the precision and quality of the formwork.

[0003] Curved surface fair-faced concrete generally has steel formwork, glass steel formwork and wood formwork.

[0004] The steel formwork and the glass steel formwork have good forming effects, but have high costs and are difficult to install on site. Ordinary straight wood formwork cannot meet the forming requirements due to the curved surface changes of the curved surface fair-faced concrete, and most of the wood formwork is processed into a standardized formwork in a factory. However, the traditional wood formwork is easily deformed during transportation and installation according to the traditional formwork, and it is difficult to adjust the curved surface on site, so the manufacturing and installation of the wood formwork must be carried out on site. SUMMARY

[0006] The film-coated plate comprises an inner formwork and an outer formwork.

[0007] The concrete wall is in a circular ring structure and is located between the inner formwork and the outer formwork.

[0008] The inner formwork and the outer formwork are connected by a tension bolt.

[0009] The inner formwork and the outer formwork are arranged with a plurality of wood square rib plates on the side away from the concrete wall, so as to ensure that the film-coated plate panel is uniformly stressed.

[0023] If the quotient value is an integer, under the requirement of the maximum distance, the distance between adjacent counter-bolts is 1 / k of the short side length of the standard film-coated plate, and the distance between the counter-bolt and the edge of the film-coated plate is 1 / 2k, k is a positive integer value;

[0024] 4) According to the maximum distance requirement between the wooden rib plate and the counter-bolt, the distance requirement between adjacent counter-bolts, and the edge distance requirement, the counter-bolt holes are opened on the processed film-coated plate or the standard film-coated plate;

[0025] 5) According to the parameters of the curved formwork on the inside and outside of the circular building, the film-coated plate and the wooden beam are processed to arch;

[0026] 6) According to the maximum distance requirement between the wooden rib plate and the counter-bolt, the wooden beam is fixed on the film-coated plate as a rib plate to form a ribbed formwork.

[0027] Further, the parameters of the curved formwork on the inside and outside of the circular building include the size, curvature and arching standard of the two side formworks.

[0028] Further, the cross-sectional shape of the standard film-coated plate and the processed film-coated plate is rectangular, and the long side and the short side of the rectangle are in a multiple relationship.
