Disclosure of Invention

The to-be-solved technical problem of the utility model is: how to make the water and electricity spool can not the draw-in groove when threading, save construction period, practice thrift construction cost.

In order to solve the technical problem, the technical scheme of the utility model a reducing sleeve based on assembled is provided, a serial communication port, include with the pre-buried first tub of sealing connection's of operation hole upper end second pipe, with the pre-buried fourth tub of sealing connection's of operation hole lower extreme third pipe, the pipe diameter of second pipe is less than the pipe diameter of third pipe, through gradual change pipe transitional coupling between second pipe and the third pipe.

Preferably, the second pipe and the third pipe are made of PVC.

Preferably, the caliber of the second pipe is the same as the caliber of a fourth pipe pre-embedded at the lower end of the operation hole, and the caliber of the third pipe is the same as the caliber of the first pipe pre-embedded at the upper end of the operation hole.

Preferably, the outer diameter of the second tube is matched with the inner diameter of the first tube, and the outer diameter of the fourth tube is matched with the inner diameter of the third tube.

Preferably, the pipe diameters of the second pipe and the fourth pipe are the same as those of the design drawing; the pipe diameters of the third pipe and the first pipe are both larger than those of the design drawing.

The utility model discloses a reducing sleeve pipe is convenient for install, comprises different bore spool, utilizes the pipe diameter difference to come the work of mutually supporting, finally reaches a purpose that saves time and save labour. The utility model discloses a reducing sleeve pipe can use in the construction procedure of civil engineering construction and the installation of the integral shear wall structure water and electricity of assembly, and the construction is simple and convenient, reduces construction cost, and safe and reliable avoids the construction loaded down with trivial details, and can use for a long time.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

The utility model relates to a reducing sleeve based on assembled, as shown in fig. 1-7, it includes with the pre-buried first pipe 1 sealing connection's of operation hole 6 upper ends second pipe 2, with the pre-buried fourth pipe 4 sealing connection's of operation hole 6 lower extremes third pipe 3, the pipe diameter of second pipe 2 is less than the pipe diameter of third pipe 3, manages 5 transitional coupling through the gradual change between second pipe 2 and the third pipe 3. The outer diameter of the second tube 2 matches the inner diameter of the first tube 1 and the outer diameter of the fourth tube 4 matches the inner diameter of the third tube 3.

The pipe diameters of the second pipe 2 and the fourth pipe 4 are the same as those of the design drawing; the pipe diameters of the third pipe 3 and the first pipe 1 are both larger than those of the design drawing. The second tube 2, the third tube 3 and the gradual change tube 5 are of an integrated structure. The second tube 2, the third tube 3, the first tube 1 and the fourth tube 4 are all made of PVC materials.

The caliber of the second pipe 2 positioned at one end of the reducing sleeve is the same as that of the fourth pipe 4 pre-embedded at the lower end of the operation hole 6, and the caliber of the third pipe 3 positioned at the other end of the reducing sleeve is the same as that of the first pipe 1 pre-embedded at the upper end of the operation hole 6. The operation hole 6 is used for connecting the threading pipes in the prefabricated wall panel.

The utility model discloses a reducing sleeve's use as follows:

the method comprises the following steps: pre-burying a first pipe 1 with a diameter slightly larger than that of a design drawing at the upper end of an operation hole 6 of a prefabricated wall plate according to the drawing size, and pre-burying a fourth pipe 4 with the same diameter as that of the design drawing at the lower end of the operation hole 6;

step two: after the prefabricated wall board is installed, the water and electricity are subjected to a sleeve program, and the reducing sleeve of the utility model is placed according to the upper part and the lower part;

step three: coating the outer sides of the second pipe 2 at one end of the reducing sleeve and the pre-buried fourth pipe 4 at the lower end of the operation hole 6 with special glue for connecting pipes in advance;

step four: when the water and electrician takes over the pipe, the second pipe 2 at one end of the reducing sleeve pipe is inserted into the first pipe 1 pre-buried at the upper end of the operation hole 6 by utilizing the pipe diameter difference, and the third pipe 3 at the other end of the reducing sleeve pipe is sleeved outside the fourth pipe 4 pre-buried at the lower end of the operation hole 6;

step five: after the installation is accomplished, treat the glue performance, be about to the utility model discloses a reducing sleeve pipe is fixed in the centre, supplies later stage threading operation.

Wherein, the first pipe 1 of reserving in prefabricated wallboard upper end can not be less than drawing design spool bore according to the standard requirement, so reserve a little more with the bore of the first pipe 1 of reserving in prefabricated wallboard upper end, makes things convenient for reducing sleeve pipe upper end disect insertion to install. The upper end of the reducing sleeve adopts a second pipe 2 with the same caliber as required by a drawing, a third pipe 3 at the lower end is slightly larger than the caliber required by the drawing, a fourth pipe 4 reserved at the lower end of the prefabricated wallboard can be directly sleeved in, and the fourth pipe 4 reserved at the lower end of the prefabricated wallboard is designed to have the same caliber as the drawing.
