Detailed Description

Preferred embodiments of the present application are described in detail below with reference to examples. However, it should be understood by those skilled in the art that these exemplary embodiments are not meant to limit the present application in any way. Furthermore, the features in the embodiments of the present application may be combined with each other without conflict. In different figures, identical components are denoted by identical reference numerals and other components are omitted for the sake of brevity, but this does not indicate that other components may not be included. It should be understood that the dimensions, proportions and numbers of elements in the drawings are not intended to limit the present application.

Herein, unless otherwise specified, "axial" means an extending direction of a rotation axis about which the connecting cylinder 23 rotates, "radial" means a radial direction with respect to the rotation axis, and "circumferential" means a circumferential direction with respect to the rotation axis, i.e., a direction surrounding the rotation axis.

As shown in fig. 1 and 2, a positioning device 1 according to an embodiment of the present application includes a bracket 10, a support rod 20, and a plumb bob 30.

Specifically, the bracket 10 is integrally formed in an elongated rod shape, the bracket 10 is movably and vertically placed on the ground, an annular installation groove 11 is formed at the upper portion of the bracket 10, a sleeve 23 at the end of the support rod 20 is rotatably sleeved on the installation groove 11, and the support rod 20 is perpendicular to the bracket 10.

The support rod 20 in this embodiment is a long round rod, the connection rod 21 is configured on the support rod 20, the connection rod 21 is perpendicular to the support rod 20, and the connection rod 21 is symmetrically distributed on two sides of the support rod 20.

For example, the connecting rod 21 is also held vertically to the bracket 10, that is, the connecting rod 21 is held horizontally.

Alternatively, the connecting rod 21 is integrally formed with the support rod 20.

In this embodiment, the two hammers 30 are hung on the connecting rod 21, and the two hammers 30 are symmetrically arranged on two sides of the supporting rod 20, and the plane of the two hammers 30 is perpendicular to the supporting rod 20.

The positions of the two hammers 30 can be adjusted by rotating the support bar 20, and the two hammers 30 are aligned with the ground mark 3 preset on the ground.

It should be noted that, in order to easily determine the position of the hammer 30, the length of the line of the hammer 30 is preferably set to ensure that the hammer body is slightly above the ground.

In this embodiment, the outer end of the supporting rod 20 is bent vertically upwards and then horizontally outwards to form the positioning portion 22, the positioning portion 22 includes a vertical section 221 and a horizontal section 222, the vertical section 221 is perpendicular to the supporting rod 20, and the horizontal section 222 is parallel to the supporting rod 20.

It should be noted that the plane where the positioning portion 22 is located is parallel to the plumb bob 30 and perpendicular to the plane where the plumb bob 30 is located, that is, the positioning portion 22, the support rod 20 and the bracket 10 are located on the same vertical plane, and the vertical plane is perpendicular to the plane where the two plumb bob 30 are located.

It can be understood that, because the two hammers 30 are aligned with the ground mark 3, the two hammers 30 are in the same plane with the ground mark and the plane is perpendicular to the cross section of the guardrail, and because the plane of the positioning portion 22 is also perpendicular to the plane of the two hammers 30, the plane of the positioning portion 22 is parallel to the cross section of the guardrail, so that the framework steel bar 2 and the cross section of the guardrail can be parallel as long as the bending portion of the framework steel bar 2 and the positioning portion 22 are in the same plane.

It can also be understood that, because the outside butt of the kink of skeleton reinforcing bar 2 is in vertical section 221, the top butt is in horizontal segment 222, consequently, through the perpendicular distance of injecing vertical section 221 and ground marking 33, can guarantee the vertical degree of skeleton reinforcing bar 2 installation, and in the same way, through the difference in height of injecing horizontal segment 222 and ground, can guarantee the mounting height of skeleton reinforcing bar 2.

It should be noted that, when the positioning device 1 is applied, it should be ensured that the bent portion of the framework steel bar 2 abuts against the inner side of the positioning portion 22, so as to ensure the accuracy of the framework steel bar 2 during installation, and after the framework steel bar 2 is positioned, the framework steel bar 2 and the embedded steel bar 4 are welded and fixed.

Although embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and should not be construed as limiting the present application, and that changes, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art within the scope of the present application.
