Abstract

The present invention relates to a manhole mold for coupling connection pipes capable of adjusting the height. The manhole mold forms a manhole by using an inner mold and an outer mold. The outer mold includes a frame; an outer plate which is coupled to the frame and has a through hole for coupling connection pipes; and an auxiliary outer plate for controlling the height that the outer plate is coupled to the frame.

Description

[0001] The present invention relates to a manhole for connecting a height-adjustable connecting pipe,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a manhole form, and more particularly, to a manhole form for connection to a manhole, which can easily form a joining part even if the joining angle and height are changed.

In order to construct a wall or a column in a modern building or a civil engineering site, the plate is poured into a desired shape and then concrete is poured therein to cure and then the form is separated.

The manhole is installed at every interval so that the manager can access the water supply, sewage, power line, communication line, etc. for repair or inspection after the land is buried underground. A common method of manufacturing such a manhole uses a form.

Prior art for such a circular tube-shaped form includes applications 10-2000-0087617 and 10-2007-0089730 filed in the Korean Intellectual Property Office.

In order to join the connecting pipe connected to the manhole in the process of forming the manhole, conventionally, in the process of forming the manhole in advance using the cylindrical mold, a hole is formed larger than the connecting pipe, .

However, the conventional manhole making method has a problem that it is difficult to cope with a case where the height at which the connecting pipe and the manhole are connected is changed or the connecting angle is changed.

The height adjustable manhole form connecting manhole form according to the present invention provides a height adjustable manhole form connecting manhole form applicable to a height and a connecting angle of a connecting pipe connected to a manhole, There is a purpose.

A manhole form for manhole connection according to the present invention is a manhole form for forming a manhole through an inner formwork and an outer formwork, the outer formwork comprising a frame, a through hole for connecting the connecting pipe, And an auxiliary outer sheath for adjusting a height at which the outer sheath is coupled to the frame.

The outer mold is formed by stacking an upper outer mold and a lower outer mold, and a plurality of protrusions are formed on an upper surface of the lower outer mold to determine a fastening angle.

The height adjustable manhole form for connecting pipe can adjust the height of the shell plate coupled to the frame of the outer formwork and adjust the angle at which the upper formwork and the lower formwork are fastened, Even if the angle is changed, there is an advantage that it can be easily applied in the field.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view illustrating a manhole form for connecting a connecting pipe, which is adjustable in height, according to a preferred embodiment of the present invention; FIG.
2 is a perspective view illustrating a height-adjustable manhole form for connecting a connecting pipe according to another preferred embodiment of the present invention.
3 is an enlarged view of Fig.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view illustrating a manhole form for connecting a connecting pipe, which can be adjusted in height, according to a preferred embodiment of the present invention.

The height-adjustable connecting pipe manhole formwork according to the present invention includes a manhole former for forming a manhole through an inner formwork and an outer formwork, which is the same as a form used in a conventional manhole forming method.

That is, a concrete molding is put in a space between an inner mold and an outer mold to form a manhole through curing. In this manhole forming process, a connector mold is used to connect the connecting pipe connected to the manhole.

However, the present invention includes the frame 110, the outer plate 120, and the auxiliary outer plate 130 in the outer mold.

First, the frame 110 is a basic frame that forms the framework of the outer formwork, and is made of iron material. The outer plate 120 is coupled to the frame 110 and has a through-hole 122 for connection pipe connection.

Here, the connection pipe is inserted through the through hole 122 and connected to the manhole through the concrete molding.

As shown in FIG. 1, the height at which the coupling pipe is coupled with the manhole can be changed according to the field conditions. In order to solve this problem, an auxiliary sheathing 130 for adjusting the height of the outer sheathing 120 to be fixed to the frame 110 is additionally coupled to the frame. Here, as shown in FIG. 1, the outer plate 120 and the auxiliary outer plate 130 are formed in the form of an arc in the case of a cylindrical manhole.

That is, when the outer panel 120 is coupled as in the case where the left auxiliary outer panel 130 is coupled to the frame 110 as shown in FIG. 1, adjustment can be performed even when the connection pipe is engaged at a high position, (120) are coupled at a low position.

The frame 110 is coupled to the outer panel 120 and the auxiliary outer panel 130 by forming guide grooves on the inner side of the frame and fastening both ends of the outer panel 120 and the auxiliary outer panel 130 to the guide grooves Method is preferably used.

2 is a perspective view illustrating a height-adjustable manhole form for connecting a connecting pipe according to another preferred embodiment of the present invention.

The embodiment shown in FIG. 2 is divided into an upper outer mold and a lower outer mold, and is different from the example shown in FIG. 1 in that the height difference at which connection pipes are connected is different or the connecting angles are different .

That is, the outer mold can be formed by stacking the upper outer mold 102 and the lower outer mold 104, and the tightening angle between the lower outer mold 104 and the upper outer mold 102 can be changed.

3 is an enlarged view of Fig.

As shown in FIG. 3, a plurality of protrusions 103 may be formed on the upper surface of the lower outer mold 104 to adjust the angle at which the upper outer mold 102 is coupled.

That is, the lower outer mold is fixed according to the connection angle of the connection pipe connected to the lower mold, and then the angle of the upper outer mold is adjusted according to the connection angle of the connection pipe coupled to the upper outer mold .

As described above, it is a principal object of the present invention to provide a height-adjustable manhole form for connecting a connecting pipe, and since the above-described embodiment is only one embodiment with reference to the drawings, Should be determined by the claims.
