Description

Cast-in-situ curved roof shaping device and use method Technical Field The invention relates to a cast-in-situ curved roof shaping device and a using method thereof, belonging to the technical field of building construction. Background In the traditional construction, the building roof is mainly a flat roof, the European building is mainly a sloping roof and an inclined roof, the construction technology of the roof is basically mature, the construction difficulty is low, in recent years, in order to pursue the effect of the outer facade of the building and design bright spots, more and more buildings begin to adopt curved roof design, and as shown in fig. 1, the curved roof 10 is fixed on the upright post 9. In the prior art, the design of the curved roof is generally realized through cast-in-situ curved roof, but the cast-in-situ Qu Wumian is difficult to control the radian and accurately position, a custom aluminum template is generally selected for construction, the aluminum template deepening processing and manufacturing period is long in the implementation process, the cast-in-situ curved roof is often used as a key line of a single building period in project construction organization planning, and the secondary deepening processing period can greatly delay project construction progress. And aluminum mould is expensive, curved roofing aluminum mould board of different radians can't circulate, can cause the wasting of resources, is contrary with the construction requirement of "green energy-conserving". If the construction of the wood template is adopted, the problems of installation, fixation and the like of the wood template are encountered, the construction is difficult, and the precision is difficult to ensure. Disclosure of Invention The invention aims to solve the technical problems in the prior art by providing a cast-in-situ curved roof shaping device and a using method thereof. The technical scheme includes that the cast-in-situ curved roof shaping device comprises more than one bone segment, all the bone segments are connected end to end in sequence, one of two adjacent bone segments can only rotate unidirectionally relative to the other bone segment, and the cast-in-situ curved roof shaping device further comprises a jacking supporting the bone segments. Preferably, an outer ratchet wheel is arranged at the upward end of the condyle, an inner ratchet wheel is arranged at the downward end of the condyle, and two adjacent condyles are connected through the inner ratchet wheel and the outer ratchet wheel. Preferably, a square hole is formed in one end, close to the inner ratchet wheel, of the bone segment, and a square rod is connected to the jacking in a rotating mode. Preferably, the length of the condyle is provided with three forms of long, medium and short. Preferably, the jacking is Y-shaped, the square rod penetrates through the square hole, fang Gandui is used for limiting the square hole, a first ratchet wheel fixed with the square rod is arranged on the jacking, and the first ratchet wheel is connected with a pawl. The invention also discloses a using method of the cast-in-situ curved roof shaping device, which comprises the following steps, S1, measuring and paying-off; s2, erecting upright posts, installing a novel jacking, and connecting jacking control points into a required arc shape; S3, installing a curved roof keel, wherein the curved roof keel is formed by installing a plurality of bone segments, the bone segments are sequentially installed from top to bottom according to the curved roof, square holes on the bone segments are matched with square rods on the jacking, and the radian of the bone segments is adjusted to meet the requirement by rotating a ratchet wheel on the jacking in the installation process; s4, fixing the upright post with the main keel; S5, installing a transverse keel; S6, installing a wood template and shaping the wood template; s7, binding reinforcing steel bars, installing a top template and pouring concrete. Compared with the prior art, the invention has the beneficial effects that the arc-shaped roof is decomposed into a plurality of straight line segments which are replaced by straight curved surfaces, so that the control in the construction and process is convenient, the manufacturing period is short, the price is low, curved roofs with different radians can be mutually circulated, and the processing precision is high.
