Embodiment Construction

[0045] In order to make the technical purpose, technical solution and beneficial effect of the present invention clearer, the technical solution of the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0046] The construction method in this embodiment is mainly aimed at the wing-shaped corner cornices of the roof of the eastern Henan style building in the late Qing Dynasty and early Ming Dynasty. Angle of 45 degrees, and with the tilting of the slope, there is a wing angle beam (1). 2. The wing angle beam is centered, and the two sides of the wing angle beam are symmetrically arranged wing angle cornices (including wing angle rafters and warping rafters). 3. The eaves rafters (202) on both sides of the wing angle beams are installed with increasing inclinations from the main rafters of the imitation Qing Dynasty building, and gradually lengthened with the old angle beams (called rushing out), and at the same time gra...

Abstract

The invention relates to a construction method for a wing-shaped cornice of a cast-in-place concrete roof. The construction method includes applying a building information model to deepen the design of the cornice, providing data information of each control point and control line in the model, and drawing a general layout. Figures; formwork design and production; formwork construction, pouring concrete and formwork removal for wing corner cornices. The space curvature of the cornice board constructed by the invention is uniform and symmetrical, the section size of the wing corner rafters is uniform, the spacing changes are uniform, the wing corners are symmetrically arranged, the line surface is smooth and straight, and the concrete looks good, which ensures the wing corner rafters and warped flying. The ancient architectural features of the twisted rafters also improve work efficiency.

Description

technical field [0001] The invention relates to the field of ancient buildings, in particular to a construction method for wing-shaped cornices of cast-in-situ concrete roofs. Background technique [0002] According to data review, modern reinforced concrete structure ancient building roof wing angle cornice construction mostly adopts cast-in-place cornice board first, and after the cornice board formwork is removed, the prefabricated rafters are installed on the bottom surface. After this method is formed, the effect of wing angle cornice board is not good. First of all, the rafters cannot achieve the effect of twisting, skimming and slanting of ancient rafters. After installation, they are relatively rigid and cannot reflect the smoothness of plane and vertical hyperbolic Effect. Secondly, the root of the rafters of the wing corner eaves and the bottom curved surface of the wing corner cornice board are connected and on the same arc surface, and the bending and warping of...
