Description

Technical Field

[0001] The utility model relates to the technical field of prestressed tendon support frames, in particular to a vertical prestressed tendon support frame for a wall anchored in a raft slab. Background Technique

[0002] With the gradually complex design of buildings, in order to meet the requirements of structural bearing capacity, deformation and crack control, prestressed tendons are increasingly widely used in beam, slab, wall and column components in building structures. The prestressed tendons in beams and slabs are generally laid horizontally along with the beam and slab steel bars, and the anchorage end and the tension end are both relatively easy to construct. In the wall, the prestressed tendons are generally laid vertically, the anchorage end is left in the concrete, and the tension end is at the top of the wall. The lateral stiffness of the prestressed tendon is extremely small, and it needs to be fixed or supported when laid vertically.

[0003] Existing construction techniques generally lay the vertical prestressed tendons flat on the top surface of the raft slab steel bars, or set up support frames on the work surface where support frames can be erected. The former is easy to contaminate the prestressed tendons or cause the anchorage end of the prestressed tendons to be fixed in the concrete raft slab, and the concrete needs to be chiseled to ensure the construction quality of prestressing. The latter can only solve the construction method when the raft slab and the vertical prestressed tendons can be cast separately.

[0004] However, there are still the following disadvantages: when the prestressed tendons are anchored in the raft slab, there is no support or fixing work surface for the support frame. Constructing according to the traditional scheme will cause pollution of the wall prestressed tendons. Therefore, a vertical prestressed tendon support frame for a wall anchored in the raft slab is designed. Content of the Utility Model
