Abstract
The utility model relates to a prestress anchor bearing plate which can prevent cracks from being produced and improve durability of a concrete structure. Anchor bars are arranged on the anchor bearing plate at the area provided with indirect reinforcement steel bars (helical reinforcement or square grid reinforcement), and positions and gaps of the anchor bars are the same as those of the indirect reinforcement steel bars. The indirect reinforcement steel bars are bound or welded with the anchor bearing plate through the anchor bars. In a construction process, positions of the anchor bearing plate and the indirect reinforcement steel bars can be fixed relatively, a phenomenon of being easy to shift in the prior art due to the fact that the anchor bearing plate is bound with a construction member reinforcement steel bar is avoided, the indirect reinforcement steel bars can develop effects fully, and crack resistance and durability of a local bearing portion of the concrete construction member are improved.
Description
Affiliated technical field
The utility model relates to a kind of prestress steel bar stretching and anchoring device, especially can be convenient to the prestressed anchor backing plate that the degree of safety of prestressed concrete member was arranged and improved to Indirect reinforcement.
Background technology
At present, known anchor plate is comprised of anchor plate and supporting Indirect reinforcement (spiral reinforcement or grid reinforcing bar), colligation is fixed between Indirect reinforcement and the member reinforcing steel bar, during prestressed reinforcement stretch-draw, huge prestressing will pass to concrete by ground tackle and following little backing plate area thereof, therefore, concrete under the anchor plate is bearing very large local stress, it may make member produce longitudinal crack, even destroy, at component partial confined area configuration Indirect reinforcement, can obviously improve the crack resistance of partial pressing, prevent the generation in crack, improve the durability of concrete structure.But, in the practice of construction process, because the Indirect reinforcement colligation is insecure, in the concrete vibrating process, easily is shifted, comes off, thereby cause member the crack to occur, the safety of concrete structure is caused a hidden trouble.
Summary of the invention
Insecure in order to overcome existing anchor plate Indirect reinforcement colligation, the deficiency that easily is shifted, the utility model provides a kind of prestressed anchor backing plate, and this prestressed anchor backing plate can not only make Indirect reinforcement easily by the designing requirement setting, and Indirect reinforcement firmly is connected with anchor plate.
The technical scheme that its technical problem that solves the utility model adopts is: set up anchor bar at anchor plate, anchor bar is arranged on the zone of configuration Indirect reinforcement, its position, spacing are consistent with position, spacing that Indirect reinforcement is laid, Indirect reinforcement is by anchor bar and anchor plate colligation or weld together, in work progress, anchor plate will be relative fixing with the position of Indirect reinforcement, stopped original phenomenon of being shifted of easily occurring with the member reinforcing steel bar colligation, made Indirect reinforcement can give full play to its due effect.
The beneficial effects of the utility model are, in the prestressed concrete member work progress, have guaranteed the relative fixing of anchor plate and Indirect reinforcement position, thereby have improved crack resistance and the durability at concrete component partial pressing position, and are simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is constructional drawing of the present utility model.
1. anchor plates among the figure, 2. Indirect reinforcement, 3. anchor bar, 4. prestressed reinforcement.
3 anchor bars for setting up at anchor plate, its position, spacing are consistent with position, the spacing of Indirect reinforcement 2 layings.
The specific embodiment
Below in conjunction with accompanying drawing, the technical scheme that prestressed anchor backing plate of the present utility model is taked is described further.Its static structure is asked Shenfu figure: as shown in the figure, prestressed anchor backing plate of the present utility model mainly is made of anchor plate 1, Indirect reinforcement 2, anchor bar 3, prestressed reinforcement 4.In shape, structure and combination thereof, the prestressed anchor backing plate of the present utility model technical characterictic different from immediate prior art is: set up vertical anchor bar 3 on the anchor plate 1, be combined into the fixed structure with tree-shaped projection, its function has been the fixedly effect of Indirect reinforcement 2.During the concrete component construction, Indirect reinforcement 2 is in place afterwards and anchor bar 3 colligations or welding, the then concreting set up on the anchor plate.So just realized the purpose of the technical problem that prestressed anchor backing plate solution Indirect reinforcement of the present utility model and anchor plate firmly are connected.
Claims (1)
1. prestressed anchor backing plate is characterized in that: set up anchor bar on the anchor plate, anchor bar is arranged on the zone of configuration Indirect reinforcement, and its position, spacing are consistent with position, the spacing of Indirect reinforcement laying.
