Problems solved by technology
However, due to the limitation of architectural design conditions, when the design direction of some arch structures is irregular, and the span of the arch structure changes along the longitudinal direction, the above installation method will cause the difference in the protruding length of the abutments on both sides of the arch structure to be too large. The construction of the arch structure is difficult, and seriously endangers the force balance and stability of the arch structure, and there is room for improvement

Embodiment
[0037] See attached image 3 , a method for arranging prefabricated arched structures adapted to irregular plane shapes, comprising the following steps:
[0038] S1. Design and arrangement of prefabricated arch slabs,
[0039] S1.1. Mark the dividing points of the sidelines on the longitudinal sides of the arch structure design plane. The basis for marking the dividing points is the change of the sideline type on any side. The sideline types include straight lines and arcs;
[0040] S1.2. Draw a vertical line through the dividing point on the sideline of each side to the arc sideline or straight sideline of the opposite side, and use the vertical line as the dividing line to form several plane partitions;
[0041] S1.3. According to the arc sidelines or straight sidelines on both sides of the corresponding plane partition, make the longitudinal centerline 4 along the direction of the corresponding plane partition in the corresponding plane partition;
[0042] S1.4. Build abu...

The invention discloses a method for arranging prefabricated arch structures adapting to special-shaped planar shapes, which includes the following steps: S1. Design and arrange prefabricated arch panels. S1.2. Draw a vertical line to the arc or straight side line on the opposite side through the boundary point on each side line, and use the vertical line as the boundary line to form several plane partitions; S1.3. According to The arc edge or straight edge on both sides of each plane partition shall be used as the longitudinal centerline along the longitudinal direction of the corresponding plane partition in the corresponding plane partition; The prefabricated arch plates are arranged between the two abutments, and the midpoint of the center line of any prefabricated arch plate is projected on the longitudinal center line in a plan view. The invention has the advantages of reducing the construction difficulty of the prefabricated arch structure and improving the force balance and stability of the prefabricated arch structure.
Description
technical field [0001] The invention relates to the technical field of prefabricated arch structure construction, in particular to a method for arranging prefabricated arch structures adapted to irregular plane shapes. Background technique [0002] The arch structure has been widely used in engineering because of its large bearing capacity, reasonable structural force and beautiful appearance. The prefabricated arch structure has a large application market in structural construction due to its fast construction speed and high component processing precision. [0003] For the convenience of making the prefabricated arch structure, the size of each prefabricated arch slab is the same. When assembling the arch structure, the existing method is to first divide the side line on site, and the side line is divided according to the two side edges of the span of the arch structure; then, the abutment is poured along the side line at the two side lines; The direction of the abutments...
