Embodiment Construction

[0032] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 A movable arch form structure is shown, including: a front arch form, a middle arch form, a rear arch form and a formwork arranged between two adjacent arch forms for forming a pouring groove;

[0033] The front arch mold 1, the middle arch mold 2 and the rear arch mold 3 are all semicircular arc arch molds, and are all assembled by two 1 / 4 arc half molds;

[0034] Among them, each 1 / 4 arc-shaped half-mold is composed of a steel inner ring, a steel outer ring, and a number of reinforcing steel ribs welded between the inner ring and the outer ring; every two 1 / 4 arc-shaped half-molds are It is top butt joint assembly, and the top of each 1 / 4 arc half-mold is provided with a longitudinally arranged butt plate B, and the bottom of the butt plate B is provided with a butt sleeve A, and the butt joint at the top of each 1 / 4 arc half-mold After the steel plate B is bonded, the through holes of the two part...

Abstract

The invention discloses a movable arch formwork structure, comprising: a front arch form, a middle arch form, a rear arch form and a formwork arranged between two adjacent arch forms for forming a pouring groove; a front arch form, a middle arch form Both the arch mold and the rear arch mold are semi-arc arch molds, and are composed of two 1 / 4 arc half molds assembled; wherein, each 1 / 4 arc half mold is a steel inner ring, a steel outer ring and It is composed of a number of reinforcing steel ribs welded between the inner ring and the outer ring; every two 1 / 4 arc half molds are assembled at the top, and the top of each 1 / 4 arc half mold is provided with a longitudinally arranged Butt joint steel plate, butt joint sleeve is arranged under the joint steel plate, and after the butt joint steel plate at the top of each 1 / 4 arc-shaped mold half is pasted, the through holes of the two parts of the joint sleeve are just aligned with the axial holes, and then through the insertion The pin rod realizes connection and fixation; the present invention adopting the above-mentioned technical solution has a simple docking process and a stable structure, and the structure after the docking can realize relative rotation, which is convenient for subsequent disassembly and storage work.

Description

technical field [0001] The present invention relates to formwork structures for constructing arched roofs or arched bridges. Background technique [0002] At present, with the further strengthening of engineering construction, many aspects of construction involve the arched roof structure. The arched roof structure not only has a strong bearing capacity, but also saves materials. When constructing an arched roof, it must not only meet the semicircular design requirements of the roof, but also require easy disassembly. Especially in the construction below the ground, the entire formwork must also be convenient. take out. Existing arch formworks are generally designed to be integrated, and adopt an integrated structure, which is inconvenient to take out when working below the ground where the space is relatively narrow. Therefore, it is particularly important to provide a structure that can precisely control the semicircular arc top and facilitate formwork removal for constr...
