Description

Technical Field

[0001] The utility model relates to the technical field of reinforced concrete structures, in particular to a shear wall surface post-planted steel bar anchoring structure. Background Art

[0002] In renovation and reinforcement projects, when beams or floor slabs are added to the outside of the concrete shear wall, it is often necessary to plant reinforcement outside the shear wall. Due to the limited thickness of the existing shear wall, the anchorage length of the post-anchored reinforcement often cannot meet the requirements. Due to insufficient anchorage length, the stress on the reinforcement cannot be guaranteed. To meet the anchorage length requirements as much as possible, the diameter of the reinforcement can generally be reduced as much as possible to meet the anchorage length requirements. However, for beam reinforcement, due to the large stress on the beam, the diameter of the longitudinal stress-bearing reinforcement of the beam cannot be too small. Under the condition of a certain wall thickness, the reinforcement anchorage length cannot meet the requirements. To this end, we propose a post-anchorage reinforcement anchorage structure outside the shear wall. Utility Model Content

[0003] The purpose of the utility model is to provide a post-planted steel bar anchoring structure outside a shear wall surface to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a post-planted steel bar anchoring structure outside a shear wall, comprising a concrete wall, one side of the concrete wall being connected to a beam, and a post-anchor steel bar inserted into the interior of the concrete wall, one end of the post-anchor steel bar passing through the interior of the beam, and the other end of the post-anchor steel bar passing through the surface of the concrete wall, and a back steel plate being fixedly connected to the surface of one end of the post-anchor steel bar located outside the concrete wall, and the back steel plate is in contact with the surface of the concrete wall.

[0005] Preferably, one end of the rear anchoring steel bar exposed outside the concrete wall is provided with a thread, and a bolt is installed on the surface of the rear anchoring steel bar through the thread, and the bolt abuts against the surface of the back steel plate.

[0006] Preferably, the end of the rear anchoring steel bar exposed outside the concrete wall is not provided with a thread, and the rear anchoring steel bar is welded to the back steel plate.

[0007] Compared with the existing technology, the beneficial effects of the present invention are: this scheme improves the anchoring effect of the rear anchoring steel bars and meets the force requirements of the rear anchoring steel bars through the structural setting of the rear anchoring steel bars, the back steel plate and the bolts, and solves the anchoring problem of thin wall steel bars. At the same time, the back steel plate and the rear anchoring steel bars can be fixed with bolts or welding, which further improves the convenience of installation of the device.

[0010] Example

[0011] See also Figure 1 , the utility model provides a technical solution:

[0012] A post-anchoring structure for steel bars outside a shear wall: a beam 2 is fixedly connected to one side of a concrete wall 1, and post-anchoring steel bars 3 are inserted into the interior of the concrete wall 1. One end of the post-anchoring steel bars 3 extends into the interior of the beam 2, and the other end of the post-anchoring steel bars 3 extends to the surface of the concrete wall 1. A backing steel plate 4 is fixedly connected to the surface of the end of the post-anchoring steel bars 3 located outside the concrete wall 1, and the backing steel plate 4 contacts the surface of the concrete wall 1. The structural arrangement of the post-anchoring steel bars 3 and the backing steel plate 4 improves the anchorage of the post-anchoring steel bars 3, meets the force requirements of the post-anchoring steel bars 3, and solves the problem of steel bar anchoring in thin walls.

[0013] The end of the rear anchor steel bar 3 exposed outside the concrete wall 1 is provided with a thread, and the back steel plate 4 is fixed by a bolt 5. The end of the rear anchor steel bar 3 exposed outside the concrete wall 1 is not provided with a thread, and the back steel plate 4 is welded and fixed to the rear anchor steel bar 3.
