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 arch structures adapted to special-shaped plane shapes, comprising the following steps:
[0038] S1. Design and arrangement of prefabricated arch slabs,
[0039] S1.1. Mark the boundary points of the side lines on the longitudinal sides of the arch structure design plane. The boundary points are marked on the basis of the change of the type of side lines on any side. The types of side lines include straight lines and arcs;
[0040] S1.2. Make a vertical line to the arc edge or straight line on the opposite side through the dividing point on each side line, and use the vertical line as the dividing line to form several plane partitions;
[0041] S1.3. According to the arc edge or straight edge on both sides of the corresponding plane partition, make the longitudinal center line 4 along the corresponding plane partition in the corresponding plane partition;
[0042] S1.4. Establish arches 1 along the edge line...

The invention discloses a prefabricated arch structure arrangement method adapting to a special-shaped plane shape. The method comprises the following steps of S1, designing and arranging prefabricated arch slabs, specifically, S1.1, marking boundary points of side lines on the two longitudinal side lines of an arch structure design plane graph; S1.2, making vertical lines from the boundary pointson the side line on each side to the arc side line or the straight side line on the opposite side, and forming a plurality of plane partitions by taking the vertical lines as demarcation lines; S1.3,according to the arc sidelines or the straight sidelines on the two sides of each plane partition, making a longitudinal center line in the corresponding plane partition in the longitudinal directionof the corresponding plane partition; and S1.4, establishing arch supports at the side lines of the two sides of the plane partition along the side lines, arranging prefabricated arch plates betweenthe two arch supports, and enabling the midpoint of the center line of any prefabricated arch plate to be projected to the longitudinal center line in an overlooking mode. The method has the advantages that the construction difficulty of the prefabricated arch structure is reduced, and the stress balance and stability of the prefabricated arch structure are improved.
Description
technical field [0001] The invention relates to the technical field of prefabricated arch structure construction, in particular to a prefabricated arch structure arranging method adapted to special-shaped plane shapes. Background technique [0002] 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 accuracy. [0003] In order to facilitate the fabrication of the prefabricated arch structure, the dimensions of each prefabricated arch slab are the same. When assembling the arch structure, the existing practice is to first divide the edge line on the site, and the edge line is divided according to the two sides of the span of the arch structure; then, the arch seat is poured along the edge line at the two sides; The arches are erec...
