Embodiment Construction

[0014] Such as figure 1 As shown, the construction linear control mold of the main arch ring includes top main ribs 1 , bottom main ribs 2 , multiple first V-shaped pieces 3 and multiple second V-shaped pieces 4 on the same plane. Both the top main reinforcement and the bottom main reinforcement are bent according to the span and camber of the main arch ring. The radial distance between the top main reinforcement and the bottom main reinforcement is equal to the thickness of the arch ring after removing the top side protection layer. The arc formed between the top main reinforcement and the bottom main reinforcement The shaped area matches the shape of the main arch ring with the top protection layer removed. The openings of the first V-shaped piece and the second V-shaped piece are both facing the bottom main rib, and along the length direction of the arc-shaped area, the first V-shaped piece and the second V-shaped piece are arranged alternately in sequence. The tip of the ...

Abstract

The invention provides a mold for controlling the construction line shape of a main arch ring, which comprises top main ribs, bottom main ribs, multiple first V-shaped pieces and multiple second V-shaped pieces on the same plane. The span and arch are bent, the openings of the first V-shaped piece and the second V-shaped piece are facing the bottom main rib, along the length direction of the arc area, the first V-shaped piece and the second V-shaped piece are arranged alternately in sequence, The tip of the first V-shaped piece is fixedly connected to the top main rib, the two open ends of the first V-shaped piece are fixedly connected to the bottom main rib, and the two open ends of the second V-shaped piece are fixedly connected to the bottom main rib, belonging to the first V respectively. The two adjacent open ends of the shaped piece and the second V-shaped piece coincide with the fixed connection points of the bottom main rib. Utilizing the stability of the triangle makes the structure of the main arch ring linear control mold stable and strong in deformation resistance, which can effectively solve the problem of difficult control of the main arch ring linear shape.

Description

technical field [0001] The invention relates to the technical field of construction of a cast-in-place reinforced concrete arch bridge and a main arch ring, in particular to a mold for controlling the appearance and linear shape of the main arch ring. Background technique [0002] In the construction process of arch bridges, the construction of the main arch ring is the key point of bridge construction, and the problem that the line shape of the arch ring is difficult to control is often encountered in the construction process of the main arch ring, especially in the construction method of the earth mold arch tire. Because the method of hanging wire construction is unstable and difficult to control, it brings great inconvenience to the construction. Often, the alignment of the arch tire and bottom mold is not accurate, resulting in poor control of the alignment of the entire main arch circle, which affects the appearance quality of the arch bridge.
