Description

Technical Field

[0001] The invention belongs to the technical field of reinforced molds, and in particular relates to a forming template for chamfering the outer corners of a steel mold. Background Art

[0002] Fair-faced concrete refers to the concrete construction that is completed without any coating or mounting on the surface. The original texture and feel of the concrete are maintained in appearance. After the concrete solidifies and hardens, it generally appears gray, with the characteristics of being unpretentious, heavy and elegant, showing a kind of plain concrete technology. It is mostly used in ancient or retro buildings. The appearance of fair-faced concrete buildings may seem simple, but it is a kind of noble simplicity. It does not seek luxury or clichés, but has a heavy and elegant architectural emotion, which has a great decorative effect. Now the scope of application is becoming more and more extensive. Fair-faced concrete has perfect decorative effect, excellent waterproof and durable Acidity and alkalinity have been widely used in many fields, such as parking posts, signboards, subway tunnels, etc. used in the municipal field. Benches, walls, floors, sculptures, flower beds, etc. in garden landscapes can all be made of fair-faced concrete. It not only has decorative effects but is also strong and durable, and has good weather resistance. In addition, when modern buildings are delivered, if it is a rough house, such a house can achieve the decorative effect of fair-faced concrete through imitation fair-faced concrete technology. After decoration, it has the most essential beauty. Fair-faced concrete is also a highly plastic material. By processing the mold, the shape of the fair-faced concrete can be made more complex, and you can create any shape you want.

[0003] Since fair-faced concrete is formed in one go, it is not easy to repair or chisel, and does not require plastering, which greatly reduces the generation of construction waste and creates a comfortable living environment for us; fair-faced concrete is naturally stable, with a simple appearance and taste, and unlike some decorative materials that are elegant and heavy, fair-faced concrete itself has a warm, soft, and rigid feeling, which not only has a great impact on our sensory experience, but also can express the feeling of the building. Therefore, most architects believe that fair-faced concrete looks simple, but it is more in line with the needs of modern aesthetics than magnificent decorations. It can be said to be a gorgeous and simple way; since fair-faced concrete is formed in one go and does not require other decorations, the use of chemical products such as paint and finishes is abandoned, which reduces the cost of later maintenance. The construction of fair-faced concrete adopts dry hanging, which is simple to construct, reduces on-site operations and the generation of a large amount of construction waste, and is beneficial to environmental protection.

[0004] The Chinese invention patent with publication number CN107489271A (application number: CN201610412734.X) provides a large-section ultra-high-definition water-repellent concrete column formwork with four-corner arc grooves and a construction method.

The middle flat plate is concave toward the inside of the formwork, and the arc plate is bent toward the inside of the formwork. Then they are assembled in a certain order to form a column formwork with four sides closed, and then channel steel is welded on the outside for reinforcement. The formwork and construction method can ensure the appearance quality of the concrete. Due to the reasonable design of the formwork, the efficiency of formwork assembly and dismantling is greatly improved.
