Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a formed steel bar used for a prefabricated plate. Background Art

[0002] At present, with the rapid development of prefabricated buildings in my country, the construction method of prefabricated slabs is becoming more and more common. However, whether it is a fully prefabricated slab or a prefabricated composite slab, most of them require extended reinforcement. The current reinforcement method of prefabricated slabs is roughly the same as that of cast-in-place slabs, using separate reinforcement, and setting a 180° hook at the end of the bottom reinforcement and a 90° hook at the upper reinforcement of the slab.

[0003] Separate reinforcement is not easy to automate during factory prefabrication, and the hooks on the protruding reinforcement of the prefabricated panels increase the difficulty of demoulding during prefabricated panel production. This prefabricated panel reinforcement method currently commonly used in the market increases the difficulty of automated production and has high labor costs. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a formed steel bar for plate prefabricated parts, which can solve the problem that the steel bars are not easy to be automatically formed due to separate reinforcement and the problem that the extended steel bars with hooks affect the demoulding, and can significantly improve the automation level of plate prefabricated parts production.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A shaped steel bar for a plate prefabricated part, comprising a first serpentine steel bar and a second serpentine steel bar;

[0007] Preferably, the first serpentine steel bar and the second serpentine steel bar are embedded in the main body of the prefabricated plate;

[0008] Preferably, the first serpentine steel bar and the second serpentine steel bar are stacked in two layers and intersected to form a mesh, and the intersection angle is 60° to 120°; optimally, the intersection angle is 90°.

[0009] The utility model does not limit the order of the first serpentine steel bar and the second serpentine steel bar. The "first" and "second" are only used to distinguish the serpentine steel bars in two directions.

[0010] Preferably, the first serpentine steel bar and the second serpentine steel bar are both formed by mechanical staggered pulling.

[0011] Preferably, the first serpentine steel bar and the second serpentine steel bar partially extend outwards for connecting the prefabricated plate with other components.

[0012] The utility model does not limit the connection method of the first serpentine steel bar and the second serpentine steel bar at the intersection position; as the best connection method, the connection method is pressure welding. The utility model does not limit that each intersection needs to be connected.

[0013] The production process of the formed steel bar of the utility model may include the following steps:

[0014] The first serpentine steel bar and the second serpentine steel bar are produced by a drawing forming method respectively;

[0015] The first serpentine steel bar and the second serpentine steel bar are stacked and intersected, and then connected by pressure welding.

[0016] Compared with the prior art, the beneficial effects of the utility model include:

[0017] (1) The formed steel bar of the utility model has no hooks, which does not hinder the side mold from being dismantled by moving in one direction, and is conducive to automated operation;

[0018] (2) The shaped steel bar of the utility model is formed by mechanical operation to form a serpentine steel bar, which is then overlapped and welded into a mesh shape. It can be produced automatically, which is beneficial to reducing costs and improving efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figures 2-3 As shown, the first serpentine steel bar 11 and the second serpentine steel bar 12 are formed by staggered pulling of mechanical pulling cylinders 2. Before pulling, the steel bar is located in the middle of each mechanical pulling cylinder 2, and then the mechanical pulling cylinders 2 are staggered and reversely pulled to a predetermined length to form a serpentine steel bar.

[0032] It should be noted that the present invention does not limit the pulling mechanism to a cylindrical body, but may also be a pulling mechanism body of other shapes.

[0033] Preferably, the first serpentine steel bar 11 and the second serpentine steel bar 12 are stacked in two layers and intersected to form a mesh, and the intersection angle is 60° to 120°; in this embodiment, the intersection angle is 90°.

[0034] The present invention does not limit the connection method of the first serpentine steel bar 11 and the second serpentine steel bar 12 at the intersection position; the connection method of this embodiment is pressure welding connection. The present invention does not limit that every intersection point needs to be connected.

[0035] Preferably, the first serpentine steel bar 11 and the second serpentine steel bar 12 partially extend outwards for connecting the prefabricated plate with other components.

[0036] like Figure 4 As shown, the production process of the formed steel bar 1 of the utility model includes the following steps:
