Description

本発明は、吹込み用断熱材の送込み方法、送込み装置及び送込みノズルに関する。   The present invention relates to a blowing method, a feeding device, and a feeding nozzle for a blowing heat insulating material.

グラスウール、ロックウール、セルローズ等からなる小片を吹込み用断熱材とし、該断熱材を、図４に示すように、吹込み装置５１を用いて、壁５２内に吹き込む場合に、壁５２内の空間部５３が空気の逃げ場のない空間部であると、該空間部に断熱材を吹き込むのが困難であることから、内装ボードを付ける前の壁５２に、寒冷紗などのメッシュ５４を付けて断熱材５８の吹込みを行う必要がある。なお、吹込み装置５１において、５５はブロワー、５６は断熱材収容器、５７はホースである。   When a small piece made of glass wool, rock wool, cellulose, or the like is used as a heat insulating material for blowing, the heat insulating material is blown into the wall 52 using a blowing device 51 as shown in FIG. If the space 53 is a space without air escape, it is difficult to blow a heat insulating material into the space. Therefore, the wall 52 before attaching the interior board is attached with a mesh 54 such as a cold chill to insulate it. It is necessary to blow the material 58. In the blowing device 51, 55 is a blower, 56 is a heat insulating material container, and 57 is a hose.

しかしながら、リフォームなどで、建物に備えられた既存の壁の内部に断熱材を吹き込む場合は、壁に内装ボードが付けられていて壁内の空間部に空気の逃げ場がないことから、内装ボードに上記の吹込み装置５１のホース５７を差し込む差込み口を設けて吹込みを行っただけでは、断熱材を吹き込むのが困難であるか、あるいは、吹込みに長い時間を要してしまう。そのため、内蔵ボードを取り外して、図４に示すように、寒冷紗などのメッシュ５４を付けて吹込みを行い、吹込み完了後、内装ボードを付け直すしかないが、それでは、施工がきわめて厄介なものになってしまう。   However, when insulative material is blown into the existing walls of a building for renovation, etc., the interior boards are attached to the walls and there is no air escape in the space inside the walls. It is difficult to blow in the heat insulating material or it takes a long time to blow just by providing the insertion port into which the hose 57 of the blowing device 51 is inserted and blowing it. Therefore, the built-in board is removed, and as shown in FIG. 4, it is necessary to blow with a mesh 54 such as a cold chill, and after the blowing is completed, the interior board must be reattached. Become.

本発明は、上記のような問題点に鑑み、空気の逃げ場のない空間部に対してであっても、吹込み用断熱材を能率良く送り込んでいくことができる、吹込み用断熱材の送込み方法、送込み装置及び送込みノズルを提供することを課題とする。   In view of the above-described problems, the present invention provides a blown heat insulating material that can efficiently blow the blown heat insulating material even in a space without air escape. It is an object to provide a feeding method, a feeding device, and a feeding nozzle.

上記の課題は、空気の逃げ場のない空間部に吹込み用断熱材を送り込む方法であって、
断熱材吐出口よりも基端側に位置して、送込み空気を逃がすが断熱材を逃がさない空気抜き部が設けられた断熱材送込み装置を用い、
前記空間部に口を明け、送込み装置の吐出口を、空気抜き部が外に位置するように前記口にセットし、送込み装置を駆動して送込み用の空気を断熱材吐出口に向けて送ることを特徴とする、吹込み用断熱材の送込み方法によって解決される。 The above-mentioned problem is a method of sending the insulating material for blowing into the space portion where there is no escape place of air,
Using a heat insulating material feeding device provided with an air vent portion that is located on the base end side from the heat insulating material discharge port and escapes the inflow air but does not escape the heat insulating material,
Open the mouth in the space, set the discharge port of the feeding device to the mouth so that the air vent is located outside, and drive the feeding device to direct the air for feeding toward the heat insulating material discharge port This is solved by a method of feeding a thermal insulation material for blowing.

この方法では、送込み装置の断熱材吐出口よりも基端側に位置して空気抜き部が設けられているので、空気の逃げ場のない空間部の口に装置の吐出口をセットし、装置を駆動すると、送込み空気は、空気の逃げ場のない空間部には入り込めないため、空気抜き部を通じて外に排気される。そして、断熱材は、空気抜き部までを送込み空気に連れられて移動し、空気抜き部から先は、空気抜き部までを送込み空気に連れられて移動していく断熱材に後方より押し動かされ、吐出口から押し出されて、空間部内に送り込まれていく。こうして、空気の逃げ場のない空間部に対してであっても、吹込み用断熱材を能率良く送り込んでいくことができる。   In this method, since the air vent is provided on the base end side of the heat insulating material discharge port of the feeding device, the discharge port of the device is set in the mouth of the space where there is no air escape, and the device is When driven, since the inflow air cannot enter the space where there is no air escape, it is exhausted outside through the air vent. And the heat insulating material is moved to the air vent part by being brought in by the air, and the tip from the air vent part is pushed and moved from the rear by the heat insulating material to the air vent part and being moved by the air, It is pushed out from the discharge port and sent into the space. In this manner, the blowing heat insulating material can be efficiently fed even to a space where there is no air escape.

しかも、従来の吹込み装置に空気抜き口を備えさせるだけでも実施できるので、そのような実施を行う場合は、実施に要する設備コストを低く抑えることができる。   And since it can implement only by providing the conventional blowing apparatus with an air vent, when performing such implementation, the installation cost required for implementation can be suppressed low.

また、上記の課題は、断熱材吐出口よりも基端側に位置して、送込み空気を逃がすが断熱材を逃がさない空気抜き部が設けられていることを特徴とする、吹込み用断熱材の送込み装置や、断熱材吐出口よりも基端側に位置して、送込み空気を逃がすが断熱材を逃がさない空気抜き部が設けられていることを特徴とする、吹込み用断熱材の送込みノズルによっても同様に解決される。特に、送込みノズルの場合は、従来の吹込み装置にノズルを付けるだけで送込みを行っていくことも可能になる。   In addition, the above-mentioned problem is provided with a heat insulating material for blowing, which is provided on the base end side from the heat insulating material discharge port, and is provided with an air vent portion that allows air to escape but does not allow heat insulating material to escape. A heat insulating material for blowing, characterized in that an air vent part is provided on the base end side of the feeding device and the heat insulating material discharge port, and an air vent part that escapes the feeding air but does not escape the heat insulating material is provided. The same problem can be solved by the feeding nozzle. In particular, in the case of a feed nozzle, it is possible to feed by simply attaching a nozzle to a conventional blowing device.

本発明は、以上のとおりのものであるから、空気の逃げ場のない空間部に対してであっても、吹込み用断熱材を能率良く送り込んでいくことができる。   Since the present invention is as described above, the heat insulating material for blowing can be efficiently fed even to a space portion where there is no air escape.

次に、本発明の実施最良形態を図面に基づいて説明する。   Next, the best mode for carrying out the present invention will be described with reference to the drawings.

図１及び図２に示す第１実施形態おいて、１は吹込み用断熱材、２は断熱材送込み装置、３は送込みの対象である壁である。壁３は、両面に既にボード３ａ，３ａが取り付けられた建物の既設の壁からなっていて、内部４は空気の逃げ場のない空間部になっている。   In 1st Embodiment shown in FIG.1 and FIG.2, 1 is a heat insulating material for blowing, 2 is a heat insulating material feeding apparatus, 3 is the wall which is the object of feeding. The wall 3 is an existing wall of the building where the boards 3a, 3a are already attached on both sides, and the interior 4 is a space without air escape.

送込み装置２は、図１（イ）に示すように、吹込み用断熱材１を収容する収容器５と、送込み駆動源としてのブロワー６と、送込みホース７と、送込みホース７の先端部に取り付けられた送込みノズル８とを備えている。ノズル８は、図１（ロ）に示すように、先端部に広幅の扁平な断熱材吐出口９を備えると共に、該吐出口９よりも基端側に位置する周壁部分には多数のパンチング孔１０…が分散状態に明けられて空気抜き部が形成されている。各パンチング孔１０…のサイズは、断熱材１を逃がさないサイズに設定されている。また、断熱材吐出口９の幅方向中間部には遮風部１１が備えられ、遮風部１１を挟む両側から断熱材１が吐出するようになされている。なお、該遮風部１１は、図１（ハ）に示すように、省略されてもよい。   As shown in FIG. 1 (a), the feeding device 2 includes a container 5 for housing the blowing heat insulating material 1, a blower 6 as a feeding drive source, a feeding hose 7, and a feeding hose 7. And a feed nozzle 8 attached to the tip of the nozzle. As shown in FIG. 1 (b), the nozzle 8 has a flat and flat heat insulating material discharge port 9 at the tip, and a number of punching holes in the peripheral wall portion located on the base end side of the discharge port 9 10 ... are opened in a dispersed state to form air vents. The size of each punching hole 10 is set to a size that does not allow the heat insulating material 1 to escape. Further, a wind shielding portion 11 is provided in the intermediate portion in the width direction of the heat insulating material discharge port 9, and the heat insulating material 1 is discharged from both sides sandwiching the wind shielding portion 11. Note that the wind shield 11 may be omitted as shown in FIG.

壁３内の空間部４への吹込み用断熱材１の送込みは、図１（イ）に示すように、壁３の上部に送込み口１２を明け、そこに、図２（イ）（ロ）に示すように、ノズル８の吐出口９を、空気抜き部１０が外に位置するようにセットし、ブロワー６を駆動すればよい。なお、壁３に設ける送込み口１２は、ノズル８の先端部を差し込むことができる程度の孔でもよい。   As shown in FIG. 1 (a), the blowing heat insulating material 1 is fed into the space 4 in the wall 3 by opening an inlet 12 at the top of the wall 3, where FIG. As shown in (b), the discharge port 9 of the nozzle 8 may be set so that the air vent 10 is located outside and the blower 6 may be driven. Note that the inlet 12 provided in the wall 3 may be a hole to which the tip of the nozzle 8 can be inserted.

すると、ブロワー６の駆動でホース７内に送り込まれる空気は、空気の逃げ場のない壁３内の空間部４には入り込めないため、図２に示すように、ノズル８の空気抜き部１０を通じて外に排気される。そして、断熱材１は、空気抜き部１０までを送込み空気に連れられて移動し、空気抜き部１０から先は、空気抜き部１０までを送込み空気に連れられて移動していく断熱材に後方より押し動かされ、図２（イ）（ハ）に示すように、吐出口９から押し出されて、壁３内の空間部４内に送り込まれていく。こうして、空気の逃げ場のない壁３内の空間部４に対して、吹込み用断熱材１を能率良く送り込んでいくことができる。なお、断熱材１の送込みを終えた後、壁３の送込み口１２を塞げばよい。送込み口１２は小さくてよいので、壁３の修復も容易である。   Then, the air sent into the hose 7 by the drive of the blower 6 cannot enter the space portion 4 in the wall 3 where no air escapes, so that the air is discharged through the air vent portion 10 of the nozzle 8 as shown in FIG. Exhausted. And the heat insulating material 1 moves to the air vent part 10 by being brought in by the air, and from the rear to the heat insulating material from the air vent part 10 to the air vent part 10 and being moved by the air. As shown in FIGS. 2 (a) and 2 (c), they are pushed out and pushed out from the discharge port 9 and fed into the space 4 in the wall 3. Thus, the blowing insulation 1 can be efficiently fed into the space 4 in the wall 3 where no air escapes. In addition, what is necessary is just to block the inlet 12 of the wall 3 after finishing feeding of the heat insulating material 1. FIG. Since the inlet 12 may be small, the wall 3 can be easily repaired.

図３に示す第２実施形態は、空気は逃がすが断熱材は逃がさないメッシュ材１３でノズル８の周壁を形成することで空気抜き部を備えさせたもので、第１実施形態と同様の原理により、空気の逃げ場のない壁３内の空間部４に対し、吹込み用断熱材１を能率良く送り込んでいくことができる。   In the second embodiment shown in FIG. 3, the air vent is provided by forming the peripheral wall of the nozzle 8 with the mesh material 13 that allows air to escape but does not allow the heat insulating material to escape, and is based on the same principle as in the first embodiment. The heat insulating material 1 for blowing can be efficiently fed into the space 4 in the wall 3 where there is no air escape.

以上に、本発明の実施形態を示したが、本発明はこれに限られるものではなく、発明思想を逸脱しない範囲で各種の変更が可能である。例えば、本発明では、送込み装置の具体的構成に制限はなく、ブロワーと、断熱材吐出口と、空気抜き部が備えられたものであればよい。   Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in this invention, there is no restriction | limiting in the specific structure of a feeding apparatus, What is necessary is just to be provided with the blower, the heat insulating material discharge port, and the air vent part.

また、断熱材送込みの対象は、壁に限らず、空気の逃げ場のない、あるいは、空気の逃げ場のある、様々な空間部であってよい。空気の逃げ場のある空間部に対しても、本発明の送込み装置、送込みノズルを用いることで、送り込まれた断熱材に送込み空気が吹き付けられることがなく、送り込まれた断熱材の吹き散りを抑えながら、断熱材の送込みを行っていくことができる。   In addition, the target for feeding the heat insulating material is not limited to the wall, and may be various space portions where there is no air escape place or where there is an air escape place. By using the feeding device and the feeding nozzle of the present invention even in a space where air escapes, the blown-in insulation material is not blown into the sent insulation material. Insulating material can be fed while suppressing scattering.

また、本発明では、空気抜き部から抜かれる空気をブロワーに返流することで空気を循環させるようにするのもよく、その場合は、周囲の空気が送込み空気で不本意に動かされるのを防ぐことができる。   Further, in the present invention, it is also possible to circulate the air by returning the air extracted from the air vent to the blower, in which case the surrounding air is unintentionally moved by the feed air. Can be prevented.
