AI Technical Summary
In the prior art, the arc angle or 45° slope at the corner of the underside is usually secondary molded by applying mortar after concrete casting. Due to the low strength of the mortar, it is easy to hollow, resulting in difficult to ensure the waterproof quality at the corner of the underside, and the risk of leakage in the later stage is relatively high.
A concrete structure's female arc primary molding mold is designed, including vertical formwork, fixing parts and arc molds. The arc mold is equipped with a fixed structure and grooves. The groove width is consistent with the thickness of the vertical formwork. The fixing parts and the fixed structure cooperate with each other to fix the arc mold on the vertical formwork to realize the primary molding of the female arc.
Through one-time molding, the arc molding quality is improved, the quality of later waterproof construction is ensured, and the risk of leakage at the shade corners is reduced.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, and in particular relates to a one-time forming die for a concave corner arc of a concrete structure. Background Art
[0002] Outdoor concrete structures need to be waterproofed to prevent water leakage. The specification requires that arc angles or 45° slopes be made at the inner corners for waterproofing construction. Arc angles or 45° slopes are generally formed by applying mortar for secondary molding after concrete pouring. Since the mortar has low strength and is prone to hollowing, it is difficult to ensure the waterproof quality of the inner corners, and the risk of leakage in the later stage is relatively high. The mold is in the shape of an arc. When the main structure supports the formwork, it is fixed to the bottom of the vertical formwork. After the concrete is poured, the inner corner arc is formed at one time, which improves the arc molding quality and ensures the quality of waterproofing construction in the later stage.

[0006] Furthermore, the groove extends to the upper end of the arc mold, so that the upper part of the arc mold forms an L-shaped structure.
[0007] Furthermore, the L-shaped structure includes a support plate and a support platform, the support plate and the support platform are integrally formed, and the fixing structure is arranged on the support plate.
[0008] Furthermore, the support plate is a rectangular plate-shaped structure to facilitate plug-in cooperation with the vertical formwork, and the lower part of the support platform is an arc-shaped structure to facilitate casting to form a concave corner arc.
