Description

Technical Field

[0001] The utility model relates to the technical field of building moulds, in particular to a chamfering mould for a foundation platform of a transformer substation. Background Art

[0002] Usually, during the construction of substation projects, the upper surface corners of the foundation platform concrete components are all right angles. This right-angle shape not only has rigid lines and lacks aesthetic appeal, but also causes stress concentration at the right angles after forming. It is easy for the upper surface corners of the components to collapse and break due to subsequent construction processes, making it very difficult to protect the finished product.

[0003] For example, a Chinese patent (publication number: CN205134356U) discloses a chamfering mold for a substation foundation platform, which mainly solves the problems of high cost, easy wear and low chamfer quality of the chamfering mold in the prior art. It includes a steel plate mold, a chamfering mold, a positioning plate and an L-shaped connecting plate; wherein the outer side of the steel plate mold has a skirt surrounded by a first side and a second side, and the second side is provided with a second connecting hole; the L-shaped connecting plate is in the shape of an angle steel, and the connecting parts on both sides thereof are respectively connected to the adjacent steel plate molds by bolting so that the two steel plate molds are spliced ​​at 90°; the chamfering mold is a long strip structure with a quarter arc shape with a concave lower side, a guide bolt is provided on the upper side of the chamfering mold, and the ends of the two adjacent chamfering molds are spliced ​​by chamfering with a tip; the positioning plate is clamped and fixed on the skirt, and the guide bolt is inserted into the positioning plate and is provided with a limit nut. It has a simple structure and is easy to operate, can realize the recycling of the mold, and effectively improves the construction quality.

[0004] The above-mentioned substation foundation platform chamfering mold still has certain shortcomings. The positioning plate is fixed to the skirt through a slot, and the guide bolt is inserted into the positioning plate, and a limit nut is provided on the guide bolt. In specific use, the chamfering mold can be moved up and down relative to the steel plate mold by adjusting the limit nut. However, after the chamfering mold moves downward, it is limited by the limit nut. However, there is a certain gap between the chamfering mold and the positioning plate. The chamfering mold will move downward under the action of external force, and the chamfering mold cannot be stably fixed. Therefore, the present application proposes a substation foundation platform chamfering mold to solve the above problems. Utility Model Content
