Description

  The present invention relates to the field of a wall penetrating device fixed to a wall hole.

  The wall penetrating device fixes a frame material composed of a cylindrical portion and an edge portion to which an elastic seal material is attached to a wall hole by a fixing means. At the time of fixing, the elastic seal material of the cylindrical portion may be rubbed or broken by friction, resulting in a gap. Since this fixing mistake is blocked by the edge, the fixing operator cannot confirm. For this reason, the water droplet which propagates an outer wall leaks to an inner wall side through a wall hole.

  Therefore, in Patent Document 1, the size of the dharma type ring is adjusted with a turnbuckle. However, there is a risk of water leakage because an elastic sealing material cannot be attached to the turnbuckle joint of the Dalma ring. Further, since the Dalma type ring is screwed to the wall, the Dalma type ring is distorted by tightening the screw to form a gap, which may cause water leakage. Furthermore, since the screw hole is formed on the side of the wall hole, the wall may collapse and leak water.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding components are denoted by the same reference numerals.
The wall penetrating device includes an edge member disposed in the front opening of the wall body, a cylindrical member disposed in the wall hole, a back member serving as a connecting means for mounting and fixing to the wall body, and an outer peripheral portion of the cylindrical member. The cylindrical member is configured as a diameter-enlarged body made of a variable-shaped cylindrical member that can be expanded in diameter separately from the edge member, and is configured by adhering an elastic seal member to the entire periphery thereof.

  As a specific example, in the wall penetrating device of FIG. 1, the deformable cylinder member 10 having the elastic seal member 11 attached to the entire circumference, the edge member having the elastic seal member 21 attached separately from the variable cylinder member 10. A frame member is constituted by the connecting member 24 having a U-shape in plan view and connecting the edge member 20 to the variable cylindrical member 10.

Next, the assembly procedure will be described with reference to FIGS.
First, the deformable cylindrical member 10 is fixed to the wall hole H of the wall W (FIG. 2A). As shown in FIG. 1, the deformable cylindrical member 10 has the cutting part 12 in the axis ax direction. Therefore, if the left and right sides are shifted in the axis ax direction as indicated by dotted lines at the cutting part 12, the diameter is larger than the wall hole H. Further, the elastic seal member 11 can be fixed without being bent or broken. Thus, the deformable cylindrical member 10 functions as a diameter-expandable body that can be expanded separately from the edge member, and the elastic seal member 11 can be uniformly brought into close contact with the inner peripheral surface of the wall hole H without difficulty. it can.

  Subsequently, the edge member 20 is brought into intimate contact with one end of the deformable cylindrical member 10, and the elastic seal members 11 and 21 are brought into contact with each other (FIG. 2B). Furthermore, the plate portion 24A of the connecting means 24 is applied to the struts 22 in the radial direction of the edge member 20, and the engaging portion 24B is brought closer to the inner wall (FIG. 2 (c)).

  Here, when the nut 25 is tightened on the bolt 23 of the support 22, the nut 25 presses the plate portion 24 </ b> A against the support 22. As a result, the edge member 20 integral with the column 22 presses the outer wall, the engaging portions 24B of the plate portion 24A engage with the inner wall from both sides of the column 22 through the variable shape cylindrical member 10, and the edge member 20 is variable. It is connected to one end of the cylindrical member 10 (FIG. 2D). Finally, the cover 30 is fixed by the nut 31 and the assembly is completed when the pipe P is passed (FIG. 3). Thus, the connecting means 24 functions as a back member that is attached to the support column 22 as a projecting body that projects in the radial direction and engages with the inner surface of the wall body.

The effect of the invention will be described with reference to FIG.
In the prior art of FIG. 4B, as described above, the elastic seal member 121 is rolled or broken in the wall hole H to form a gap. In addition, this fixing mistake is blocked by the edge member 120 and cannot be confirmed by the fixing operator. For this reason, water droplets attached to the location a on the outer wall, which is often decorated, are transmitted through the location b between the outer wall and the elastic seal member 121 and leak to the inner wall side through the location c of the wall hole H.

  On the other hand, in the invention of FIG. 4A, the diameter of the deformable cylindrical member 10 can be deformed to be smaller than that of the wall hole H, so that the elastic seal member 11 can be in close contact with the wall hole H without being bent or broken. Further, since the deformable cylindrical member 10 is separate from the edge member 20, the fixing operator can confirm and repair a fixing error without being blocked by the edge member 20. Therefore, even if a water droplet is transmitted from the location a to the location b on the outer wall, it does not pass through the location c.

  Further, since the edge member 20 is brought into intimate contact with one end of the deformable cylindrical member 10 by the connecting means 24 and the elastic seal members 11 and 21 are brought into contact with each other, the elastic seal member 11 is disposed around the entire circumference of the variable cylindrical member 10. As compared with Patent Document 1 using a turnbuckle, there is no place where the elastic seal member 11 cannot be pasted, and it can be waterproofed reliably. And it becomes waterproof at the location x where the elastic seal members 11 and 21 come into contact with each other, and the waterproof performance is improved.

  Furthermore, since the deformable cylindrical member 10 and the edge member 20 are coupled by the support column 22 and the connecting means 24, a screw or a screw hole is unnecessary, and the deformation of the deformable cylindrical member 10 and the collapse of the wall W can be prevented. Can be reliably waterproofed.

  Further, as shown in FIG. 5A, the pair of bent portions 13 to which the elastic seal member 11 is attached by bending the cut portion 12 to the inner peripheral side are formed at the time of fixing. The elastic seal members 11 come into contact with each other, and the cut portion 12 is reliably waterproofed.

In addition, there are the following variations.
<Variable shape cylindrical member>
In FIG. 1, the deformable cylindrical member 10 is easily deformed and easily fixed to the wall hole H by providing the cutting portion 12, but in addition to this, for example, as shown in FIG. If the variable shape cylindrical member 10 is divided by forming 12, the deformation of the variable shape cylindrical member 10 becomes easier and it becomes easier to fix to the wall hole H.

<Secondary waterproof>
A waterproof member 40 such as a hood may be provided on the outer wall side as shown in FIG. 6A, or the edge portion 14 provided with the elastic seal member 15 as shown in FIGS. You may provide in the other end of the variable shape cylinder member 10. FIG. By these, secondary waterproofing becomes possible and waterproof performance improves.

<Connecting means>
As shown in FIG. 7, when the edge member 20 is brought into close contact with one end of the deformable cylinder member 10, a number of elastic engagement portions 26 that engage the inner wall through the deformable cylinder member 10 are connected to the edge member 20 as connection means. It may be provided. The elastic engagement portion 26 functions as a back member that integrally attaches and fixes the edge member 20 and the variable shape cylindrical member 10 to the wall hole portion, and prevents deformation of the variable shape cylindrical member 10 and collapse of the wall W. The support 22 is not required, and the penetrating portion in the wall penetrating apparatus is expanded, so that the application is expanded.

  Note that the deformable cylindrical member 10 may be pressed against the inner periphery of the wall hole H by the elastic engagement portion 26 during the connection. Since the elastic seal member 11 of the deformable cylinder member 10 is pressed against the inner periphery of the wall hole H, it can be reliably waterproofed. This method is particularly effective when the deformable cylindrical member 10 is divided into a prismatic shape at the cutting part 12 and the elastic seal member 11 is difficult to adhere to the wall hole H as shown in FIG. That is, with respect to the right side portion of the square hole, the leg portion of the elastic engagement portion 26 acts elastically in the direction of expanding the diameter of the deformable cylindrical member 10, thereby ensuring the water stoppage by the elastic seal member 11. it can.

  As shown in FIG. 9, several connecting stays 16 and 27 that make a pair may be provided on the deformable cylindrical member 10 and the edge member 20 as connecting means. In FIG. 9, the bolts 28 and the nuts 29 are connected. In addition to preventing the deformation of the deformable cylindrical member 10 and the collapse of the wall W, the support 22 is not required, and the penetration portion in the wall penetrating device is widened, thereby widening the use. As the fixing means, for example, some of the engaging portions 17 that press against the inner wall side are provided on the deformable cylindrical member 10. In this case, if the diameter of the deformable cylindrical member 10 is changed to be smaller than that of the wall hole H as indicated by a dotted line, it can be fixed even from the outer wall side.

<Opening and closing configuration>
