Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, and in particular relates to a vertical reinforcement positioning device for vertical prefabricated components and its usage method. Background Technology

[0002] With the increasing prefabricated construction projects in cities, the quality of vertical prefabricated components such as precast walls and columns is receiving more and more attention. The positioning of vertical reinforcing bars in vertical prefabricated components is very important in the installation of these components, especially the positioning of vertical reinforcing bars in the first-floor vertical prefabricated components. This positioning is particularly important in the entire installation of vertical prefabricated components, determining many quality aspects such as quality deviation and installation. Therefore, whether the vertical reinforcing bars are installed in place is the key to determining the quality of vertical prefabricated components. Summary of the Invention

[0005] When one vertical insert is adjacent to multiple vertical inserts, preferably, the positioning unit is provided with multiple sets of connecting rods, each set of connecting rods corresponding one-to-one with adjacent vertical inserts. That is, each set of connecting rods corresponds to one adjacent vertical insert, each adjacent vertical insert corresponds to a set of connecting rods, and the other end of the set of connecting rods points to the adjacent vertical insert. Each set of connecting rods has one or more connecting rods, and the connecting rods are arranged vertically. To improve the positioning between adjacent vertical inserts, preferably, each set of connecting rods has at least two connecting rods. Preferably, the vertical inserts are arranged in an array, such as a rectangular array.

[0006] The structure of the fastener is not limited. As a preferred structure, the fastener has a through hole, the diameter of which matches the diameter of the vertical insert, allowing the vertical insert to be inserted into the through hole to form a tight seal. More preferably, the fastener is cubic in shape, and the through hole is a coaxial through hole running from the top to the bottom of the cube. As another preferred structure, the fastener has an internal hollow structure, with a first through hole at one end and a second through hole at the other end. The diameters of the first and second through holes match the diameter of the vertical insert, allowing the vertical insert to be inserted through the first through hole, pass through the hollow interior, and exit through the second through hole to form a tight seal. Preferably, the diameter of both the first and second through holes is adjustable. For example, the first through hole may be equipped with a spring structure for diameter adjustment; the second through hole may also be equipped with a spring structure for diameter adjustment.

[0007] The structure of the fastener is not limited. Preferably, the fastener is a screw and a nut, the connecting rod is provided with a through hole, the screw can pass through the through hole and can be displaced along the length of the connecting rod within the through hole; when the connecting rods of adjacent positioning units are connected, one end of the screw passes through the through holes of the connecting rods of two adjacent positioning units in sequence and is then fastened by the nut.

[0008] When positioning vertical reinforcing bars using the vertical reinforcing bar positioning device of the present invention, the following steps are included: (1) Fix the fasteners of each positioning unit to the outer periphery of the adjacent vertical reinforcing bars respectively; (2) Adjust the spacing between adjacent vertical inserts by adjusting the connection position of the connecting rods of adjacent positioning units, and then fix the connection position with fasteners.

[0009] When forming vertical precast members by casting, the following steps (3) and (4) are performed after step (2): (3) Concrete is poured between adjacent vertical reinforcing bars to form vertical precast members; (4) Remove all fasteners and remove all positioning units from each vertical insert.

[0010] Compared with the prior art, the present invention uses a fixing component and a connecting rod to form a positioning unit. Several positioning units are respectively set on adjacent vertical inserts. The connecting rods of adjacent positioning units are fastened with fasteners at adjustable intervals, thereby realizing the positioning of adjacent vertical inserts. It has the following beneficial effects: (1) The vertical bar positioning device of the present invention has a simple structure, low cost and is easy to install; (2) In this invention, after the fixing member is fixed to the vertical insert, the spacing between the adjacent vertical inserts can be adjusted by adjusting the connection position of the connecting rod of the adjacent positioning unit, so that each vertical insert can be adjusted to the position expected in construction. This adjustment method is simple and easy to implement, can save labor and costs, and can achieve accurate positioning of each vertical insert. (3) When the vertical bar positioning device of the present invention is used to cast and form vertical precast components, the construction is safe and reliable, and the efficiency is high. The vertical bar positioning in the obtained vertical precast components is accurate and of high quality, especially suitable for the first-floor vertical precast components.
