Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to the attached drawing 1, the pile top elevation control device of the utility model is shown, which comprises a PVC through pipe 1 and a rod member 2, wherein two ends of the rod member 2 in the length direction are respectively provided with a template 3, the templates 3 are slidably connected with the inner wall of the PVC through pipe 1, a pipe orifice at the first end of the PVC through pipe is radially provided with a limiting part, and the length specifications of the rod member and the PVC through pipe 1 at least meet the following requirements: when the template at the first end of the rod piece is contacted with the limiting piece, the template at the second end of the rod piece is flush with the pipe orifice at the second end of the PVC through pipe (or slightly higher than the pipe orifice). The second end of the PVC through pipe is provided with a handle bar, one side of the handle bar is connected with an annular part, the annular part is sleeved on the outer wall of the PVC through pipe, and the pile top elevation control device can be positioned by utilizing the handle bar, if the handle bar is fixed on an external pile casing. Wherein, the rod is preferably a light rigid rod.

Specifically, in this embodiment, the PVC pipe 1 is a circular pipe, the template 3 is a circular plate, the shape of the template 3 is consistent with the shape of the pipe orifice of the PVC pipe 1, and the diameter of the template 3 is equal to (or slightly smaller than) the inner diameter of the pipe orifice of the PVC pipe 1, the inner wall of the PVC pipe 1 should be kept smooth or a lubricant should be used to reduce the friction coefficient so as to reduce the friction between the template 3 and the inner wall of the PVC pipe 1, so that the template 3 can slide up and down along the inner wall, when concrete begins to be poured, the template 3 in the device will start to rise synchronously with the rise of the concrete surface, during the use, in order to avoid the template 3 at the first end of the rod 2 falling off, the pipe orifice at the first end of the PVC pipe 1 is provided with a stopper 4 in the radial direction, during the use, the first end of the PVC pipe 1 is aligned to the area to be poured, and at the same time, for the convenience of measurement and calculation, when the template of member 2 first end and locating part 4 contact, the template 3 of member 2 second end is flushed with the second end mouth of pipe of PVC siphunculus 1 (or is a little higher than the mouth of pipe), can calculate like this and confirm that concrete placement is accomplished the face height present ground elevation (measurable) + the come-up height-device length of template 3.

In order to avoid the device to influence the use because of rocking, be close to 1 second end department of PVC siphunculus and be equipped with barre 5, one side of barre 5 is connected with annular portion 6, annular portion 6 cup joints on 1 outer wall of PVC siphunculus, has certain gap between barre 5 and the PVC siphunculus 1, before the operative installations, can be with pour the section of thick bamboo wall embedding gap of district outside protection section of thick bamboo, the device just can rely on barre 5 to fix the one side at outside protection section of thick bamboo like this.

Further, the rod member 2 is a lightweight rigid rod member, and in use, in order to prevent the rod member from falling into the concrete when the concrete surface rises, the rod member 2 must be lightweight so as to float on the concrete surface, and therefore, the rod member 2 is a lightweight rigid rod member, and similarly, the form 3 must be lightweight together, and specifically, the rod member 2 and the form 3 are made of an inorganic composite material using alkali-resistant glass fibers as a reinforcing material and thioaluminate low-alkalinity cement as a cementing material, and may be a lightweight galvanized wire pipe.
