Description

The present invention is a tubular body that protects the gap between the wall and the tubular body when the tubular body with a protective cover for protecting the tubular body and the insulating material covering the tubular body surface is drilled through the wall. and a cover for the gap of the peripheral hole.

Conventionally, a tubular body for supplying high-temperature or low-temperature gas or fluid covers the surface of the tubular body with a heat insulating material in order to prevent heat exchange between the internal gas/fluid and the outside air. Since such heat insulating materials have relatively low durability, in order to protect the heat insulating materials, it is common to attach a protective cover made of an iron plate or stainless steel material so as to cover the entire tubular body including the heat insulating materials. is. When this tubular body itself is installed through the wall, a gap with the wall is generated.

As gap covers, protective covers are used which respectively fit the straight sections of the tube. With this protective cover, a gap is formed between the outer peripheral surface of the straight portion of the pipe and the wall, and it is difficult to eliminate the gap.

To prevent interference of a connecting portion with the outer diameter of a straight portion of a tubular body when attaching to the tubular body, to improve wearability, and to reliably cover the gap between the outer peripheral surface of the tubular body and the wall. Gap covers between the tube and the surrounding bore have been proposed.

In the gap cover between the tubular body and the peripheral hole, as a mechanism for connecting the two inner diameter covers 8 and 7 of FIG.

In this way, the gap cover between the tubular body and the surrounding hole prevents the outer diameter cover from interfering with the wall when the tubular body passes through the wall, thereby improving the mountability to the tubular body. can be configured to effectively protect the outer diameter of the

FIG. 4 is a diagram of a mounting configuration of a gap cover between a tubular body and a surrounding hole according to the first embodiment of the present invention;

In the state of attachment so far, the connecting portion has been attached away from the outer diameter portion of the tubular body. Moreover, a gap is formed between the outer peripheral surface of the tubular body and the inner peripheral surface of the gap cover between the tubular body and the peripheral hole of the wall. Therefore, it is difficult to attach the straight portion protection cover to the straight portion of the tubular body with improved adhesion.

Moreover, when the tubular body itself is deformed, it is assumed that the cross-sectional shape is different.
Even in such a case, it was difficult to mount the linear portion protective cover in a state of improved adhesion as described above.

SUMMARY OF THE INVENTION The present invention provides a gap cover between a tube and a surrounding hole, in which the straight portions can enhance the tightness at each position to protect the straight portions of the tube.

As described above, the gap cover between the tubular body and the surrounding hole of the present invention is configured such that the end sides of the engaging teeth abut against the engaging receiving teeth 7 of the female engaging portion 2 and are fixed, thereby achieving a straight line. It is applicable to a tubular body having a part.

(Structure of gap cover between tubular body and surrounding hole)
1 to 3 show a gap cover between the tubular body and the surrounding hole of the tubular body according to the present embodiment. FIG. 4 is an installation figure.

As shown in FIG. 1, the gap cover between the tubular body and the surrounding hole is formed by bending a sheet metal into a semi-cylindrical shape so as to correspond to the linear shape of the tubular body.

When attaching the gap cover between the tubular body and the surrounding hole to the straight part of the tubular body, the straight part of the tubular body is covered with two inner diameter covers so as to sandwich the straight part of the tubular body from the outer diameter side, and the tubular body and the surrounding hole are covered. The pipe is housed in the gap cover, and the jointed portion is attached at the outer diameter of the straight portion of the tubular body. The gap cover between the tube and the surrounding bore has this juncture feature, which is described below.

FIG. 2 is a cross-sectional view of a coupling portion showing an enlarged joining portion between the tubular body of the tubular body and the outer diameter cover of the gap cover for the peripheral hole according to the present embodiment.

As shown in FIG. 3, the connecting portion is formed to have a male-female structure in which one end is inserted into the other end for connection. It is composed of a joining portion 4 and a male engaging portion 3 .

The female engaging portion 8 has a face-to-face structure into which the male engaging portion can be inserted. In addition, this facing structure is provided on the inner surface side of the first inner diameter cover body.

The female engaging portion 4 is composed of a primary bent portion 5 formed by bending an end portion of the first inner diameter cover body 1 inward, and an extension portion from the primary bent portion extending outward in the middle. Engagement as a secondary bent portion 6 formed by folding to face the same secondary bent portion and a tertiary bent portion formed by bending an extension portion from the secondary bent portion inward. A V-shaped groove portion 12 into which a male engaging portion 3 (to be described later) is inserted is formed in a facing portion between the secondary bent portion and the primary bent portion.

The male engaging portion 7, which is inserted into the V-shaped groove portion 12 of the female engaging portion 4 and connected, is connected to the engaging teeth of the female engaging portion near the end portion of the second inner diameter cover body 2. It is formed with two engaging teeth 8 .

The engagement tooth 8 is formed in the end of the second inner diameter cover body 2, and the side edge of the notch formed in the width direction is pushed out from the outer surface to the inner surface to form a convex shape. This is what I made.

The engaging teeth 8 are aligned in the vertical and horizontal directions with a predetermined interval that allows the engagement surfaces of the engagement receiving teeth 7 to be arranged, and are linear as described above. By doing so, the tip abutment surfaces T of the engagement receiving teeth can be arranged in a horizontal row.

By forming the mountain shape in this way, it is possible to arrange the front end abutting surfaces T of the engagement receiving teeth 7 at a predetermined angle and symmetrically. Then, it becomes possible to fix in a state in which the angle between the tip abutment surface T of the engagement receiving tooth and the end side that engages with the tip abutment surface T is matched. Therefore, the front end abutment surface T of the engagement receiving tooth can be brought into contact with the entire end side of the engaging tooth 8 and fixed, thereby reducing stress during fixing.

In such a configuration, when engaging the male engaging portion 3 with the female engaging portion 4, the male engaging portion is positioned between the primary bent portion 5 and the secondary bent portion 6 of the female engaging portion. is inserted into the V-shaped groove formed in 1, and is inserted and connected until the engaging receiving tooth 7 gets over the engaging tooth 8. - 特許庁Elastic force and external force of the gap cover between the tubular body and the surrounding hole are applied to the connected portion, and a force is applied in the direction in which both the inner diameter cover bodies are separated from each other. The engagement receiving tooth of the female engaging portion abuts and is fixed to the end side of the engaging tooth of one of the interlocking teeth, thereby preventing the inner diameter cover bodies from moving in the direction of separating from each other. I try to connect them.

Here, in order to form the female engaging portion 4 and the male engaging portion 3 as described above, first, the front end side of the sheet metal forming the first inner diameter cover body 1 is attached to the second inner diameter cover body. 2 by extending the length necessary for the primary bending portion 5, the secondary bending portion 6 and the tertiary bending portion 7, and the sheet metals constituting both inner diameter cover bodies are formed respectively. It is formed by die-cutting with a metal frame so that the width gradually narrows toward the tip.

Then, in the sheet metal forming the first inner diameter cover body 1, the end portion is bent inward to form a primary bent portion 5, and the extension portion from this primary bent portion is bent outward in the middle. By folding back to form a secondary folding portion 6 and by folding an extension portion from the secondary folding portion inward to form an engagement receiving tooth 7, a secondary folding from the primary folding portion 5 is performed. It can be configured so that the width becomes slightly narrower toward the tip of the engaging receiving tooth through the curved portion.

The plate width at the tip of the male engaging portion 3 is formed to correspond to the plate width of the primary bent portion 5 of the female engaging portion 4, and the gap between the primary bent portion and the secondary bent portion 6 The shape is such that it can be easily inserted into the V-shaped groove portion 12 formed in . The plate width of the male engaging portion may be any plate width that can be ensured when it is inserted into the V-shaped groove portion of the female engaging portion and connected to the engagement receiving tooth 7, and is particularly limited to this. you will not be

(Method of attaching gap cover between tube and surrounding hole)
When attaching the tubular body and the gap cover for the peripheral hole constructed in this way to the tubular body, the end portions of the first inner diameter cover body 1 and the second inner diameter cover body 2 are expanded in a direction away from each other. At the same time, the tubular body is sandwiched between the first inner diameter cover body and the second inner diameter cover body from the outer diameter side of the straight portion from this pushed-out end portion. Then, the first and second interior cover bodies are connected to each other at the connecting portion and attached to the tubular body.

When the gap cover between the tubular body and the surrounding hole is installed on the straight part of the tubular body, the protruding part is prevented from interfering with the inner diameter of the straight part of the tubular body, thereby improving the mounting performance.

FIG. 3 is an explanatory diagram showing a state in which the tubular body and the gap cover for the surrounding hole are attached to the tubular body, and FIG.

In this embodiment, it is attached to a tubular body having a straight portion with enhanced adhesion.

For mounting on such a tubular body, first, the straight part of the tubular body is covered with two inner diameter cover bodies (1, 2) so as to sandwich from the outer diameter side, and the gap cover between the tubular body and the surrounding hole is Cover the gap between the pipe body and the wall and connect the connecting parts to install.

When connecting the male engaging portion 3 to the female engaging portion 4, the male engaging portion is formed between the primary bent portion 5 and the secondary bent portion 6 of the female engaging portion. It is inserted into the groove portion and engaged by inserting until the engagement receiving tooth 7 gets over the engagement tooth 8.例文帳に追加As a result, the gap cover between the tubular body and the peripheral hole is attached so as to wrap the entire straight portion of the tubular body.

At the time of mounting, the mounting work can be performed smoothly without interfering with the outer diameter surface of the straight portion of the tubular body. It is possible to position them at an appropriate facing angle so that they can be easily inserted into the groove 12, so that the connecting work can be easily performed, and the mounting work can be smoothly performed.
