Abstract

The utility model relates to an embedded pipe for electrical equipment wires in building construction, particularly to a PVC threading pipe and a reducing casing thereof. The PVC threading pipe has a regular triangular cross section, and the inner edge and the outer edge at the 60-degree corner site are both in circular arc-shaped transition; and the pipe joint for connecting the PVC threading pipe with a junction box is a reducing pipe joint, the cross sections of one end and the other end of the pipe joint are in shapes of a regular triangle and a round respectively, and the pipe joint body between the two end surfaces are in circular arc-shaped transition. The PVC threading pipe has higher load-bearing capacity and firmer pipe body, so that the pipe is not easily damaged during construction due to the treading of workers. The PVC threading pipe is convenient for the construction and saves a large number of manpower and materials, so as to save investment.

Description

PVC penetration pipe and pipe thereof connect

Technical field:

The utility model relates to the pre-pipe laying of construction electric equipment circuit, particularly a kind of PVC penetration pipe and reducing sleeve pipe thereof.

Background technology:

At present common pvc pipe material all cross section all is circular, placing and doing in the pre-buried pipe construction process, especially in the pre-buried pipe construction process of the circuit of top board, because the contact area of circular pipe and template is very little, the workmen jam on or above when having weight to place, be very easy to be crushed, thereby cause this section pvc pipe material to be scrapped, must could use through changing.But in the practice of construction process, because workmen's limited amount, often there are many impaired tubing to be found and to change, in the threading process in later stage, can cause the plugging phenomenon after all like this, handle plugging, not only need to pick cutter top board or body of wall, thereby destruction building structure influences construction effect, and changes the repeated use that tubing can cause material, a large amount of waste materials, in addition, in the stringing work progress and in the concreting process, must must there be special workman to overhaul the tubing of damage, this has not only expended manually, also can bring inconvenience to concrete building smoothly.In the pipeline process of handling shutoff, picking cutter top board or body of wall needs a large amount of artificial, a large amount of concrete can be used in floating slit of picking cutter, and these all are very big losses, and this mending course also can have influence on the effect of wall plastering and carrying out smoothly of next process.

The utility model content:

The utility model is intended to effectively solve the problems that existing PVC penetration pipe brings to construction, and provides a kind of novel PVC penetration pipe and pipe thereof to connect.

The technical solution adopted in the utility model is: a kind of PVC penetration pipe and pipe thereof connect, and this its cross section of PVC penetration pipe is equilateral triangle, and 60 degree angles are located inside and outside edge and all are arc transition; This PVC penetration pipe is connected with terminal box with pipe and connects to reducer pipe connects, and this pipe connects one end cross section and is equilateral triangle, and other end cross section is rounded, and the pipe junctor between the both ends of the surface is arc transition.

Compared with prior art, the beneficial effects of the utility model are: bearing capacity is stronger, and body is firmer, can not damage easily because of trampling of workman in work progress, and convenient construction is saved great amount of manpower and material, thereby economized on the use of funds.

Description of drawings:

Fig. 1 is a PVC penetration pipe structural representation described in the utility model.

Fig. 2 is a PVC penetration pipe pipe joint structure schematic diagram described in the utility model.

Embodiment:

The utility model is described in further detail below in conjunction with drawings and Examples.

The described PVC penetration pipe of present embodiment is the DN20 pipe, and as shown in Figure 1, this PVC penetration pipe 1 its cross section 2 is equilateral triangle, and 60 degree angles are located inside and outside edge 3 and all are arc transition.This tube wall thickness 1.6mm, inner triangular form are that diameter is the circumscribed equilateral triangle of the circle of 16.8mm, and outside triangular form is that diameter is the circumscribed equilateral triangle of the circle of 20mm.

As shown in Figure 2, this PVC penetration pipe 1 is connected with terminal box with pipe and connects to reducer pipe connects, and this pipe connects one end cross section 5 and is equilateral triangle, and other end cross section 6 is rounded, and the pipe junctor 4 between the both ends of the surface is arc transition.

PVC penetration pipe 1 described in the utility model designs according to leg-of-mutton stability principle, the stress surface of tubing is a plane, stress surface has increased, and the pressure that can bear is greatly improved, can not trampling or the pressure of weight and infringement easily because of the workman.Its pipe inside also is the equilateral triangle structure, and does fillet respectively and handle inside and outside place, 60 degree angle, has made things convenient for the threading operation.

Because existing terminal box all be a circle, is designed to triangle so pipe described in the utility model connects the one end, the other end is designed to circle, has made things convenient for docking of PVC penetration pipe 1 and terminal box.

Claims

1. PVC penetration pipe and pipe thereof connect, and it is characterized in that this its cross section of PVC penetration pipe is equilateral triangle, and 60 degree angles are located inside and outside edge and all are arc transition; This PVC penetration pipe is connected with terminal box with pipe and connects to reducer pipe connects, and this pipe connects one end cross section and is equilateral triangle, and other end cross section is rounded, and the pipe junctor between the both ends of the surface is arc transition.
