[0017] Figure 1 It is a schematic diagram of an embodiment of the utility model;

[0018] Figure 2 The utility model is a PVC pipe positioner according to an embodiment of the utility model. DETAILED DESCRIPTION

[0019] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] A PVC pipe positioning structure temporarily supported by a post-cast strip cantilever structure, comprising a beam slab 1, wherein a groove position on the upper part of the beam slab 1 forms a casting space for the beam body, a PVC pipe 2 under the beam slab is arranged at the bottom of the beam slab 1, a beam slab through hole is provided at the bottom of the beam slab 1 corresponding to the top position of the PVC pipe 2 under the beam slab, the beam slab through hole is communicated with the center hole of the PVC pipe 2 under the beam slab, a PVC pipe positioner 4 is arranged on the upper part of the PVC pipe 2 under the beam slab, the PVC pipe positioner 4 comprises: a lower PVC pipe connecting part 3 and an upper PVC pipe positioning part 5, the lower PVC pipe connecting part 3 extends into the PVC pipe 2 under the beam slab and is fixed, and the PVC pipe positioning part 5 extends out of the highest point of the beam slab 1.

[0021] It should be noted that after the device is installed, the PVC pipe 2 under the beam and slab supports the PVC pipe locator 4, so that a part of it is inside the PVC pipe 2 under the beam and slab, thereby accurately positioning the PVC pipe locator 4. At this time, the upper PVC pipe positioning part 5 on the top of the PVC pipe locator 4 extends out of the highest point of the beam and slab 1, that is, after the beam and slab are cast, a part of it will be exposed to the outside, thereby facilitating the positioning and installation of the PVC pipe on the upper temporary supporting beam and slab.

[0022] As a preferred embodiment, the lower PVC pipe connecting part 3 includes: an upper stirrup 6, which is sleeved on the outside below the PVC pipe positioning part 5, and a plurality of upper connecting ribs 8 are arranged between the upper stirrup 6 and the PVC pipe positioning part 5 to achieve support and fixation. The upper stirrup 6 is radially provided with a plurality of limiting ribs 11 in a circumferential direction, and the limiting ribs 11 overlap the top surface of the upper edge of the PVC pipe 2 under the beam slab.

[0023] It should be noted that usually the diameter of the PVC pipe positioning part 5 is larger than the diameter of the upper stirrup 6, the upper connecting rib 8 and the limiting rib 11, so as to ensure that the middle rod will not bend. At the same time, the length of the limiting rib 11 should not be too long. If it is too long, the device will not be able to fall into the beam and slab through hole.

[0024] As a preferred embodiment, a lower stirrup 7 is provided below the upper stirrup 6 , and the lower stirrup 7 and the lower outer portion of the PVC pipe positioning portion 5 are supported and fixed by a lower connecting rib 9 .

[0025] It should be noted that, by disposing the upper stirrup 6 and the lower stirrup 7, two-level positioning is formed, so that the PVC pipe 2 under the beam slab will not shake, thereby increasing the positioning accuracy.

[0026] As a preferred embodiment, the diameter of the upper stirrup 6 is larger than that of the lower stirrup 7 and both are smaller than the inner diameter of the PVC pipe 2 under the beam and slab.

[0027] It should be noted that the structure is to form the upper stirrup 6 and the lower stirrup 7 into a truncated cone-like structure, so that they can be conveniently placed in the inner hole of the PVC pipe 2 under the beam slab.

[0028] As a preferred embodiment, a plurality of support ribs 10 are arranged on the same side surfaces of the upper stirrups 6 and the lower stirrups 7. Such a structure makes the structure between the upper stirrups 6 and the lower stirrups 7 more stable and can withstand certain lateral stresses.

[0029] As a preferred embodiment, the distance between the upper stirrup 6 and the lower stirrup 7 is greater than 100 mm. Such a setting can prevent the distance between the upper stirrup 6 and the lower stirrup 7 from being too short, resulting in unstable installation and tipping.

[0030] As a preferred embodiment, the difference between the outer diameter of the upper stirrup 6 and the lower stirrup 7 and the inner diameter of the PVC pipe 2 under the beam and slab is 10-20 mm. This arrangement makes it easy to install and the gap will not be too large, which improves the convenience of installation and the installation accuracy.

[0031] As a preferred embodiment, the top of the PVC pipe positioning part 5 has an upper PVC pipe connection part, which is similar to the lower PVC pipe connection part 3, and is in an inverted state of the lower PVC pipe connection part 3, and the limiting rib 11 structure is removed. This structure can also be omitted in actual operation. It is only necessary to accurately know the position of the PVC pipe positioning part 5, and at least no large displacement or offset error will occur in the installation by naked eyes within an acceptable range. However, in order to better improve the installation accuracy of the upper PVC pipe, this structure can also be set. By setting this structure, the upper PVC pipe can be directly inserted without the operator's naked eye judgment, thereby improving work efficiency and installation accuracy.
