Description

Technical Field

[0001] The utility model relates to a vertical steel bar positioning device, in particular to a recyclable prefabricated reserved vertical steel bar positioning and isolation device, belonging to the technical field of shear wall construction. Background Art

[0002] During the installation process of prefabricated components, the problem of vertical reserved steel bar deviation is quite intractable and not easy to control. If no measures are taken, the reserved steel bars will shift, resulting in the inability to connect the next layer of precast components. If ordinary strong steel bar correction is adopted, due to the short reserved steel bars, the performance of the steel bars will change and it does not meet the specifications, affecting the overall stability of the wall structure. Moreover, the traditional steel bar positioning device cannot be recycled and combined in various ways, which increases the operation difficulty and reduces the use efficiency.

[0021] The following further explains and illustrates the present utility model in conjunction with the drawings:

[0022] Example, see Figures 1 - 4, A recyclable precast vertical reinforcement positioning and isolation device, comprising at least two reinforcement positioning and isolation units. Each reinforcement positioning and isolation unit consists of two reinforcement positioning and isolation modules. A cross bar 601 is provided between adjacent reinforcement positioning and isolation units, and a vertical bar 602 is provided between adjacent reinforcement positioning and isolation modules. The reinforcement positioning and isolation module consists of a conical sleeve 2 and a clamping piece 4. The conical sleeve 2 is sleeved outside the steel bar 1, and a clamping piece 4 is provided between the steel bar 1 and the conical sleeve 2. A hook 5 is provided at the top of the clamping piece 4.

[0023] Both the cross bar 601 and the vertical bar 602 are composed of a hook-shaped bar 701 and a limiting bar 702. The limiting bar 702 is sleeved at the end of the hook-shaped bar 701 and fixed by bolts.

[0024] There are six clamping pieces 4, distributed in upper and lower layers, and there are three clamping pieces 4 in each layer, evenly distributed in the gap between the steel bar 1 and the conical sleeve 2.

[0025] The size of each layer of clamping pieces 4 matches the internal gap of the conical sleeve 2 of that layer.

[0026] The conical sleeve 2 is processed from aluminum.

[0027] Both the cross bar 601 and the vertical bar 602 are processed from steel plates.

[0028] An extension plate 3 is provided on the outside of the top of the conical sleeve 2, and a jack 301 is provided on the extension plate 3.

[0029] The clamping pieces 4 between the steel bar 1 and the conical sleeve 2 are in two layers, with three clamping pieces 4 evenly arranged in each layer, and the size of each layer of clamping pieces 4 matches the size between the steel bar 1 and the conical sleeve 2.

[0030] In the above description, there are six clamping pieces, distributed in upper and lower layers, with three in each layer. The size of a single clamping piece in each layer matches the size between the inner wall of the conical sleeve of that layer and the steel bar. The upper and lower layers of clamping pieces are overall distributed in a sharp cone shape, and the bottom of the lower layer of clamping pieces penetrates the bottom of the conical sleeve.

[0031] The conical sleeve 2 is processed from aluminum.

[0032] Both the cross bar 601 and the vertical bar 602 are processed from steel plates.

[0033] In the above description, the size of the jack on the extension plate satisfies that both ends of the cross bar or the vertical bar can penetrate the extension plate.

[0034] In the above description, the two reinforcement positioning and isolation units are fixed by a cross bar, and the cross bar is connected to the extension plates of the conical sleeves in the adjacent two reinforcement positioning and isolation units.

[0035] In the above description, the number of the steel bar positioning and isolating units is determined according to the length of the wall.

[0036] In the above description, the dimensions of the horizontal tie rod and the vertical tie rod are as follows: the hook-shaped rod is processed twice with a steel plate having a length of 600 - 1000 mm, a height of 30 mm, and a thickness of not less than 7 mm; the limiting rod is processed from a steel plate with a height of 50 mm and a width of 20 mm. After installing the independent isolating device, the limiting rod can freely slide along the hook-shaped rod and is fixed by the bolt outside the limiting rod to achieve the effect of controlling the spacing.
