Description

[Detailed description of the invention] [Industrial field of application] The present invention provides a method for inserting pipes so that the surroundings of the pipe insertion hole can be covered even after the pipe is inserted through the pipe insertion hole formed in the wall of a building. a cylindrical portion that fits into the hole;
It consists of an annular flange part for abutting against the surface of the building wall at one end side in the cylinder axis direction of the cylinder part, and the whole is divided into two parts in the radial direction, and the divided edges of both divided members are engaged with each other. This invention relates to a wall cap that has a connecting portion that joins together.

[Conventional technology]

Conventionally, the connecting portion of the wall cap is composed of a locking portion that can be fitted and removed only by relative movement of the two divided members toward and away from each other in the radial direction, and a protrusion for engaging the locking portion. It was on.

[Problem that the invention attempts to solve]

However, after inserting the pipe or a pipe cover containing the pipe into the pipe insertion hole in the building wall,
A cylindrical portion of the wall cap fits into the insertion hole,
In addition, when installing the pipe or pipe cover so that it fits externally, there is no space between the wall cap and the pipe,
If you try to fill the wall cap with putty or the like so that there are no gaps, or if you try to fit the wall cap and piping cover tightly together so that there are no gaps between them, stress will be applied to the wall cap in the direction of diameter expansion. As a result, there were cases in which both the divided members separated from each other.

An object of the present invention is to enable the two divided members to be connected to each other and to prevent the two divided members from separating from each other even if stress is applied in the diametrical direction.

[Means for solving problems]

The characteristic structure of the wall cap of the present invention is that the connecting portion consists of an engaging protrusion and an engaging recess that can be fitted into and separated from each other only by relative movement of both divided members in the direction of the cylinder axis. There is, and its effects are as follows.

[Effect]

In other words, in order to connect both divided members to each other,
With the cylindrical axis direction of the split member aligned with the length direction of the pipe or pipe cover, one of the split members is inserted into the pipe insertion hole of the building wall along the outer circumferential surface of the pipe or pipe cover. Then, by simply moving the other divided member along the outer circumference of the pipe or pipe cover so as to approach the insertion hole, the engaging protrusion and the engaging recess of the connecting part will fit into each other. , since the two divided members are easily connected together, and the two divided members can be separated only by relative movement in the direction of the cylinder axis, stress in the direction of diameter expansion is applied to both the divided members. Even if you do, you will never leave.

[Effect of idea]

Therefore, although the wall cap can be easily attached even after the piping or the piping cover has been inserted into the insertion hole, it is difficult to attach the wall cap and the piping or the wall cap and the piping cover, for example, between them. In order to prevent the formation of gaps, the filling can be strongly pushed in or elastically tightly fitted, ensuring that the pipe insertion holes formed in the wall are completely closed and finished neatly, ensuring a beautiful appearance. It can be adjusted to Furthermore, when the wall is an outer wall of a building, it is possible to reliably prevent rainwater and wind from entering through the pipe insertion holes.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 1 and 2, there is a cylindrical portion 4 having an inner surface having approximately the same shape and dimensions as the outer periphery of the piping cover 2 that accommodates the air conditioning piping 1, and a cylindrical axis direction of the cylindrical portion 4. It consists of an annular flange part 5 which is connected to one end side and is for abutting against the surface F of the building wall W, and the whole is divided into two in the radial direction, and the dividing edges 6 of both dividing members 3A and 3B are formed. The wall cap 3 is constructed by forming a connecting portion 7 that engages and connects the two.

As shown in FIG. 5, the wall cap 3 has a cylindrical portion 4 fitted and held in each end of an insertion hole 8 for the pipe 1 formed in the building wall W, and is connected to the cylindrical portion 4. The annular flange portion 5 is brought into contact with the surface F of the building wall W, and the piping cover 2 containing the air conditioning piping 1 is placed inside the cylindrical portion 4 so as to be in surface contact over the entire inner circumference of the cylindrical portion 4. Insert it through the insertion hole 8.
It is designed to cover the surrounding area.

As shown in FIGS. 1 to 4, the connecting portion 7 of the wall cap 3 connects the two divided members 3A,
The engaging protrusion 7A and the engaging recess 7B can be fitted into and separated from each other only by relative movement in the direction of the cylinder axis of the member 3B.
are integrally formed on the flange portion 5 and the divided edge portion 6 of the cylinder portion 4, respectively, over substantially the entire length along the cylinder axis direction.

Next, to explain how to attach the wall cap 3 to the insertion hole 8, one of the divided members 3A is attached to the piping cover 2 inserted into the insertion hole 8 of the building wall W so that the axial directions thereof are aligned with each other. After fitting the pipe cover 2 along the outer periphery of the pipe cover 2 into the pipe insertion hole 8 of the building wall W until the flange part 5 comes into contact with the wall surface F, the other divided member 3B is inserted.
While moving along the outer periphery of the piping cover 2 so as to approach the insertion hole 8, the engaging convex portion 7A of the connecting portion 7 is moved.
and the engagement recess 7B are fitted into each other by relative sliding, and when the flange portion 5 of the other divided member 7B comes into contact with the wall surface F, both the divided members 3A, 3B
are formed in one wall cap 3. Then, the pipe cover 2 is firmly and tightly fitted and held by the cylindrical part 4 of the wall cap 3 so that there is almost no gap between the two parts 3 and 2, and in this state, the flange part 5 is fixed with bolts 9 or the like. By fixing the piping cover 2 to the wall W, the piping cover 2 is stably held in position (FIG. 5).

[Another example]

Even if the engagement convex portion 7A and the engagement recess 7B are formed only in a part of the flange portion 5 and the cylinder portion 4 in addition to substantially the entire length along the cylinder axis direction, the flange portion 5
Alternatively, it may be formed only on either one of the cylindrical portions 4.

The shapes of the engaging protrusion 7A and the engaging recess 7B can be modified in various ways as long as they can be fitted into and separated from each other only by relative movement in the direction of the cylinder axis.

What is inserted through the insertion hole 8 may be only the piping 1 in addition to the piping cover 2, and the piping 1 may be used for hot water supply in addition to air conditioning. Electric wiring may be inserted and arranged.

The wall body W may be an outer wall of a building other than a wall formed inside a building.
