Embodiment Construction

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with specific embodiments and accompanying drawings. Obviously, the described embodiments are only some preferred embodiments of the present invention, not all embodiments. Those skilled in the art can make similar modifications without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0021] Such as Figure 1-8 As shown, the present invention provides a positioning device for electric pre-embedded pipes piercing concrete foundations. 8 is located in the bolt through hole 2 opened around the positioning plate 1. The positioning plate 1 is provided with a pre-embedded pipe through hole 4. During the construction process, in order to prevent the occurrence of slurry leakage, a rubber sleeve is installed on the pre-embedded pipe through hole 4. Circle ...

Abstract

The invention proposes a positioning device for electric pre-embedded pipes passing through concrete foundations. The positioning device includes a positioning plate and positioning bolts. The positioning bolts are located in the bolt through holes opened around the positioning plate, and there are pre-embedded pipe through holes on the positioning plate. And there is a rubber ferrule on the through hole of the pre-embedded pipe. This positioning device ensures the positioning accuracy of the pre-embedded pipe and completely avoids the common phenomenon of honeycomb pitting when the pre-embedded pipe pierces through the concrete foundation. At the same time, the pre-embedded pipe is nested The rubber ferrule avoids the displacement of pre-embedded pipe fittings and grout leakage caused by vibration during concrete construction.

Description

technical field [0001] The invention relates to a positioning device, in particular to a positioning device for electric pre-embedded pipes penetrating concrete foundations. Background technique [0002] In the construction process of the existing substation, according to the engineering design requirements, a large number of electrical pre-embedded pipes need to be buried on the concrete foundation of the substation, and most of the pre-embedded pipes are of multi-layer structure. In the existing substation concrete foundation construction, the pre-embedded pipes are usually positioned according to the design requirements of the drawings, by opening the pre-embedded pipe through-holes on the wooden formwork. Due to the problem of wooden materials, when opening the pre-embedded pipe through-holes, The accuracy of the through-hole of the embedded pipe cannot be guaranteed, resulting in the occurrence of problems such as insufficient concrete plugging in the later stage. Duri...
