Circular anchor backing plate and manufacturing method thereof

Abstract

The invention discloses a circular anchor backing plate, which comprises a left loading plate, a right loading plate and a circular base plate, wherein the cross sections of the left loading plate and the right loading plate are semicircular; the lower side parts of the left loading plate and the right loading plate are provided with grouting grooves; the edges of two sides of the left loading plate are provided with bulges extending outwards; the edges of two sides of the right loading plate are embedded into the bulges of the left loading plate to be fixedly connected with the left loading plate; the edges of the bottoms of the left loading plate and the right loading plate are provided with flanges extending outwards; the base plate is provided with a boss which is downwards sunken; the flanges of the left loading plate and the right loading plate are embedded into the boss of the base plate to be fixedly connected with the base plate; the boss is provided with a through hole through which a steel strand passes and grouting holes in the corresponding positions of the grouting grooves. The anchor backing plate is molded through stamping and welding, compared with a casting manufactured by a conventional process, has the advantages of being light in weight, easy to machine and high in strength, can be used for greatly improving production efficiency and is energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of anchoring devices, and in particular relates to a circular anchor backing plate and a manufacturing method thereof. Background technique [0002] The construction of roads and railways in my country is developing rapidly. In order to ensure the safety of roads and railways, the application of prestressed products is indispensable. The prestressed anchors used in concrete structures are mainly composed of anchor pads, anchor plates, clips, etc. In the construction process of beams and slabs of highways and railways, the anchor plates and reinforced spiral steel bars are pre-embedded in the concrete of the beams and slabs, and then the prestressed steel strands are passed through the anchor plates at both ends of the beams and slabs. The anchor plate and clips fix the prestressed steel strand, and then the prestressed steel strand is stretched by the tensioning machine to make the beam slab have a certain rad...

AI Technical Summary

Problems solved by technology

At present, the circular anchor backing plate is mainly cast iron or steel castings formed by integral casting, but the circular anchor backing plate processed by casting technology has the following defects: 1. The casting has many impurities and is brittle, and it is easy to burst when it is collided. A large number of waste products are easy to be generated in the transportation and construction links, which makes the reliability of the product poor and the cost is high; 2. The melting of raw materials in the casting process consumes a lot of energy, and the casting process and the machining process after casting molding generate a lot of dust, and the production environment is harsh. High energy consumption and not environmentally friendly; 3. The production process is backward, the shape and size of the castings are unstable, the shape is rough, and the manufacturing cycle is long
