A circumferential rib element rims either open end of the sleeve with at least one of them being provided with a plurality of equidistantly spaced fastening locations.

Description

A plastic pipe sleeve and its method of installation

The present invention relates to a kind of be used for staying at concrete floor establish parts that are used to connect the duct of pipe subsequently, especially relate to a kind of plastic pipe sleeve that improves feature that has.

The plastic pipe sleeve of prior art is used to stay in concrete floor establishes the used duct of sewage, refuse and stack that connects subsequently between different floorings.These pipe boxes between concrete casting is in the floor are being fixed on earlier on the template of being made by veneer usually.The pipe box of prior art has several shortcomings.Their inner and outer wall all is (continuous) do not blocked and straight.The water that spills from top first floor often goes down along the outer wall seepage of pipe box, and this can cause some horrible and antihygienic consequences.Another shortcoming is because not convenient and do not mark the reference center point definitely on the pipe box of above-mentioned prior art, thereby difficult with the second pipe aligning that is connected another floor face and connect.

One object of the present invention is to provide a kind of simple structure of blocking the outline of straight line of pipe box outer wall.

Another object of the present invention is to provide a kind of structure that forms reference center's point on pipe box.

For achieving the above object, the outer wall of pipe box of the present invention forms a plurality of circumferential reinforcements.The structure that indicates central point is to realize by the monolithic stiffener with center ring hole, and this monolithic stiffener is removably across an opening of pipe box.

Below by accompanying drawing each embodiment with above-mentioned feature is described, wherein:

Fig. 1 a is the lateral longitudinal sectional drawing of a preferred embodiment of the present invention, shows the partial cross section of cylindrical shell;

Fig. 1 b is the vertical view of the embodiment of the invention shown in Fig. 1 a;

Fig. 2 is the sectional drawing of the embodiment of the invention after preferable mounting method according to the present invention installs;

Fig. 3 is the template as shown in Figure 2 under the embodiment of the invention dismounting after concrete floor forms;

Fig. 4 shows the perpendicular that the reference center that is used for first pipe box aligns with second pipe box;

Fig. 5 a is the lateral view of second embodiment of the present invention, and the wherein planetary fixing localization part of using is away from the monolithic stiffener;

Fig. 5 b is the lateral view of the present invention as shown in Fig. 5 a, and it can be installed with a kind of using method that reverses of the present invention.

Be used in concrete floor, staying as label 10 represented one embodiment of the invention and establish one and be the used duct of connecting pipe subsequently.Pipe box of the present invention is shown in Fig. 1 a and 1b by way of example.It is a pipe box with cylinder 11 two openends, hollow basically.On the outer wall of above-mentioned cylinder, be formed with four reinforcements, in the middle of wherein two 12b, 12c are positioned at along circumference.Other two 12a, 12d are positioned at the end near each opening of above-mentioned cylinder 11.Bottom reinforcement 12d also is provided with four

localization part

13a, 13b, 13c, 13d along the equally spaced fixedly usefulness of bottom opening.

For ease of describing, there are the parts of similar characteristics all to use identical label to represent in the pipe box of the present invention.In order to distinguish and to distinguish each separate part, on same numeral, add a lowercase.It is to be noted, four fixedly localization part, four reinforcements and four stiffeners of usefulness have been shown in Fig. 1 a and 1b.Yet above-mentioned parts also can adopt three to seven.

One reference center hole 31 is arranged at the center of integrally-built stiffener 30.For example wood screw 40 such connectors pass this hole pipe box of the present invention is remained on one preferably by being positioned on the following template 50 that veneer is made.At the joint of the inwall of stiffener 30 engagement cylinder shape housings 11, the thickness of stiffener weakens and reduces, and this makes after concrete floor 60 solidifies and after glued mould 50 quilts were removed, this integral body stiffener can be pulled down from cylindrical shell inside.Abutment 32 is favourable a little more than the bottom opening of above-mentioned housing, and it is preferably in 4 to the 8mm scopes at interval.The base of stiffener 30a, 30b, 30c, 30d preferably flushes with respect to following template 50 basically in addition, just can guarantee that pipe box 10 correctly and is securely located in the process of placing of concrete.

One preferable mounting method is illustrated in Fig. 2 and 3.On template 50, be marked with pipe and will pass that of concrete floor 60.Go out an aperture that passes above-mentioned point with an iron nail.Pipe box 10 is placed on the top of template 50, the reference center hole 31 of pipe box and above-mentioned hole alignment of going out.With a wood screw 40 pipe box 10 is fixed on the template 50.In order to strengthen fixation, hammer into the planetary fixing localization part 13 of using of the bottom opening of close cylindrical shell 11 with iron nail.

After concrete casting and solidifying, stripping 50 firmly removes simultaneously and forms whole stiffener 30.The leftover and plastic at stiffener tie point 32 places can be used the file filing before connecting pipe subsequently.

For the pipe that makes in the building building sewage that connects different floorings or refuse has the exhaust system of sealing, be very important with each central point alignment of each tube connector.Referring to Fig. 4, on concrete floor, be installed with a duct among the figure.A bit of extension places above-mentioned duct.Second pipe box is placed on the top of the pipe of extension, makes the centre bore 31 of stiffener 30 become the central point of pipe.One perpendicular adjustable ground hangs from second template 50 of above-mentioned floor top, just fixes together when the bottom centre's point with pipe aligns then.In case this point is marked on second template, just in second concrete floor, stays and establish a duct with second pipe box.

Fig. 5 a represents second embodiment, wherein fixingly is set on another opening away from the cylindrical shell 11 of stiffener 30 with localization part 13.For second embodiment pipe box is being fixed on first direction on the template 50, also use four iron wire stationary positioned parts 13 in addition.

Fig. 5 b represent will the modification pipe box 10 shown in Fig. 5 a to install the other way around in a kind of alternative method.On this second direction, stiffener 30 is positioned on the bottom opening.Fixedly the localization part 13 usefulness iron nails of usefulness directly are pinned on the following template 50.

Obviously for those technician in present technique field, also can make other distortion, also can go out other mounting method according to above-mentioned Variant Design to preferred embodiment.Yet, within the protection scope of the present invention that will be disclosed above all these modification all will fall into.
