Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a positive angle reinforcement device for a clear water concrete covering template. Background Art
[0002] Fair-faced concrete is cast in one go without any external decoration. The exterior wall concrete is formed directly by the combination of the texture and feel of the main structural concrete itself and the carefully designed and constructed open joints, Zen joints and tension bolt holes. When pouring this type of concrete, it is necessary to first support the covering formwork so that the pouring can be completed smoothly.
[0003] The formwork reinforcement at the positive corner of ordinary concrete exterior wall generally adopts the form of back-rib pulling. However, due to manual pulling, the pulling force is difficult to control. Too much or too little pulling force may cause the wall at the positive corner of the exterior wall to deviate, and the verticality control effect of the wall is not good. For special-shaped fair-faced concrete exterior walls, there will be more positive corners. At the same time, since fair-faced concrete has high requirements for the one-time casting and forming effect of the facade, repairs are not allowed. Therefore, the covering formwork is reinforced in the current form of pulling, which will affect the casting effect of the fair-faced concrete. Therefore, a fair-faced concrete covering formwork positive corner reinforcement device is proposed. Utility Model Content
