Document Type and Number:
WIPO Patent Application WO/2024/061351
Kind Code:
A1
Abstract:
A construction formwork for an arc-shaped overhanging eave of a building. The construction formwork comprises a bottom formwork, end formworks and a side formwork, wherein the bottom formwork is supported below an overhanging eave by means of a scaffold, and the end formworks for the overhanging eave are correspondingly arranged at two ends of the bottom formwork; and the side formwork is arranged on an outer side of the overhanging eave, and two ends of the side formwork are correspondingly connected to end faces. The side formwork comprises a flexible formwork board, support rods and U-shaped connectors, wherein the plurality of support rods are distributed at equal intervals; any two adjacent support rods are connected by means of a U-shaped connector, and in response to the change in the degree of opening of the U-shaped connector under the action of an external force, the curvature of an arc corresponding to the side formwork correspondingly changes; and the flexible formwork board is tightly fitted to inner sides of the support rods and used for forming an outer arc-shaped face of the overhanging eave. The flexible formwork board is arranged on the inner sides of the support rods, and an outer arc-shaped face of an overhanging eave is formed by means of the flexible formwork board. The U-shaped connectors connect the support rods to each other, such that the degree of opening of the U-shaped connectors can be adjusted under the action of an external force, and when the openings of the U-shaped connectors change, the flexible formwork board can adapt to different arc-shaped curved faces.
