Description

Technical Field

[0001] This invention relates to a shaping device and method for cast-in-place curved roofs, belonging to the field of building construction technology. Background Technology

[0002] In traditional construction, building roofs are mainly flat, while European-style buildings primarily feature pitched or sloping roofs. The construction techniques for these types of roofs are generally mature and relatively easy to implement. In recent years, however, to achieve striking facade effects and design highlights, an increasing number of buildings are adopting curved roof designs, such as... Figure 1 As shown, the curved roof 10 is fixed to the column 9.

[0003] In existing technologies, curved roof designs are generally achieved through cast-in-place curved roofs. However, due to the difficulty in controlling the curvature and precisely positioning cast-in-place curved roofs, custom aluminum formwork is typically chosen for construction. This process involves a long lead time for the detailed processing of aluminum formwork. Since cast-in-place curved roofs are often considered a critical path in the project's construction schedule, the extended processing time would significantly delay the project's progress. Furthermore, aluminum formwork is expensive, and different curvatures of aluminum formwork cannot be reused, leading to resource waste and contradicting the requirements of "green and energy-saving" construction. Using wooden formwork presents challenges in installation and fixation, making construction difficult and precision hard to guarantee. Summary of the Invention

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] The reference numerals in the accompanying drawings include: joint 1, outer ratchet 2, inner ratchet 3, square hole 4, top support 5, square rod 6, first ratchet 7, pawl 8, column 9, curved roof 10.

[0025] Example 1:

[0026] A type of cast-in-place curved roof shaping device, such as Figures 2-3As shown, the structure includes a segment 1, with an outer ratchet 2 at the left end and an inner ratchet 3 at the right end. A square hole 4 is located on the right side of the segment 1, serving as a through hole. Multiple segments 1 are connected end-to-end in sequence. Adjacent segments 1 are connected by the inner ratchet 3 and the outer ratchet 2. One side of the inner ratchet 3 on segment 1 faces downwards and engages with the outer ratchet 2 of the next segment 1. The ratchet rotation direction is set so that the next segment 1 can only rotate clockwise relative to the previous segment 1. When pouring concrete, the keel formed by the segments 1 is mainly subjected to downward force. According to the ratchet principle, the resistance to reverse rotation of segment 1 is very large, which can effectively withstand the weight of the concrete, prevent deformation of the keel, and ensure the accuracy of the curved roof 10.

[0027] This embodiment also includes a top support 5, the lower end of which is fixed to the existing column 9. The top support 5 provides support for the joint 1, such as... Figure 4 As shown, the top support 5 is Y-shaped, and a square rod 6 is rotatably connected to the top support 5. A first ratchet 7 fixed to the square rod 6 is provided at the left end of the top support 5. The first ratchet 7 is connected to a pawl 8. During installation, the square rod 6 passes through the square hole 4, and the square rod 6 plays a limiting role in the square hole 4.

[0028] The first ratchet 7 is oriented to facilitate clockwise rotation of the square rod 6, while counterclockwise rotation is subject to significant resistance. Because the square hole 4 on the joint 1 is located near the inner ratchet 3, the joint 1 is installed from top to bottom, with one side of the inner ratchet 3 facing down, engaging with the outer ratchet 2 of the next joint 1, so that the square rod 6 is subjected to a counterclockwise rotation torque.

[0029] The square hole 4 cooperates with the top support 5. The top support 5 not only fixes the joint 1, but also prevents the joint 1 from rotating and deforming, thus ensuring the accuracy of the curved roof 10.

[0030] When segment 1 is fixed, only segment 1 with support 5 is fixed, and the curvature accuracy of segment 1 between the two supports 5 is maintained by segment 1 fixed by the two supports 5.

[0031] In this embodiment, the length of the joint 1 is set in three forms: long, medium and short. Except for the length, the rest of the structure is the same. During construction, the joint 1 of different lengths can be selected according to the curvature of the curved roof 10.

[0032] This embodiment also discloses a method for using a cast-in-place curved roof shaping device, including the following steps.

[0033] S1, measuring and setting out;

[0034] S2, erect column 9, install new top support 5, and connect the points controlled by top support 5 to form the required arc shape;

[0035] S3, Install the curved roof keel. The curved roof keel is made of multiple ribs 1. Install the ribs 1 from top to bottom according to the curved roof 10, so that the square holes 4 on the ribs 1 match the square rods 6 on the top support 5. During the installation process, the curvature of the ribs 1 is adjusted to meet the requirements by rotating the ratchet on the top support 5.

[0036] S4, column 9 is fixed to the main keel;

[0037] S5, install horizontal keel;

[0038] S6, Install wooden formwork, prefabricated wooden formwork;

[0039] S7, tying reinforcing bars, installing top formwork, and pouring concrete.

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of protection of the claims.
