Description

The present invention relates to a cap-type flushing structure with a roof gradient type gantry, which is installed in a house and smoothly guides flue gas generated by burning solid fuel such as firewood or coal to the flue and does not cause rain leakage. It can also be used for liquid fuel and gaseous fuel stoves and combustion products.

Traditionally, it is recommended that the chimney of the stove is well-opened, but it is known that there are many methods for removing the wall without removing the roof because of concerns about rain leaks.

In this way, even though it was said that roofing was good, there was a drawback that a roof-opening type flue could not be made due to concerns about rain leaks.

In Japan, where there is a lot of rain, a lot of skylights that are suitable for Western-style houses have recently been used, so there may be a way to reduce rain leaks.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention

The problem to be solved is considered to be a method in which rain leakage can be reduced by using a rain dampener, a draining sheet or the like like the above-mentioned skylight.
However, when a draining sheet is used for many years, a phenomenon of rain leakage occurs, which is a phenomenon caused by depending on the sealing material. It is thought that the rain leak cannot be stopped if the exclusive drainer is not used.
In Japan, there are many types of roofing materials such as roof tiles, metal sheet metal, and flat panels, so it is difficult to carry out rain.

It is generally known to perform rain by sealing material processing (caulking material).

If used carefully, the stove itself and the chimney itself will last about 20 years, but the sealing material is said to last only about 5.6 years. And since the building law has been revised and rain leaks have been determined to have a 10 year warranty, it is the responsibility of construction companies, so there are currently few construction shops that use rooftops to install flues.

There is a problem in that it results in relying on a sealing process that is said to have no years and no drainage.
Means for solving the problem

The present invention solves the above-mentioned problems of the prior art, attaches a stand in a roofless chimney, attaches an upright integrated type or drains up and down, etc., and has a chimney connection at the tip of the cap type flushing. It has been connected, a double insulation chimney with a storm collar attached to the connection chimney by laser welding etc. is connected to it, and a retrofit storm collar is attached to the connection part, of course with a roof gradient type frame Double insulation chimneys shall be installed where cap-type flushing is applied.

In order to improve the performance of rain anyway, it is necessary to prepare drainage for tiles, metal roof flats, and drainage for cement flats for the tiles, and to improve the performance of rain in the flue by adding cap-type flushing. .

The cap-type flushing structure with a roof gradient type frame according to the present invention is provided with an integrated draining or bi-directional draining, and a drainage is provided at the valley and mountain parts of the draining, and the flushing is also capped. By making it into a mold, it is possible to obtain a state in which the rain finish is remarkably improved without relying on the sealing process. A double insulation chimney is connected immediately above the cap-type flashing, a connection band is provided, and a double chimney with a fixed storm collar is attached directly by laser welding etc. A storm collar attached later is installed just above the chimney connection band, and the sealing process is performed here, so that it does not rely on the sealing as a whole, so it is a problem to provide a better rain finish. .

I would like to talk about why roofless flues are so good

時 に There is a draft effect (chimney pulling force) immediately when the stove is ignited, and the only thing that burns up is the roof removal construction. Why is the top removal, that is, the roof removal construction has good air pulling? The more you use it, the more smoothly the combustion starts from ignition and you can go to combustion in a short time.
It is said that no one can imagine that a wood stove can ignite and burn so smoothly. If the cap type flushing structure with a roof gradient type gantry according to the present invention is used without depending on the sealing process, the construction is streamlined, the process is shortened, and the rain finish is improved, so that it becomes more practical.

Embodiments of the present invention will be briefly described with reference to the drawings.

I will explain using a drawing of a cap-type flushing with a roof-gradient mount.

The base 1 is set up rather than the base plate material 11, and the integrated drainer 5 is attached so that the rainwater flows well.
In addition, the exclusive drainer 5 has never made rainwater go elsewhere by attaching a water return 13 to the valley and mountain.
For the drainer 5 on the eaves side, the water return 13 is used only as a mountain and the valley is used as a water return 13 so that rainwater can flow through the roof finish 12 immediately.

7 The inside of the penetrating part is made of calcium silicate board 7 and so on.
The wooden crate 1 is provided with a foundation so that the chimney fixing bracket 3 can be firmly attached to the wooden crate 1, and the lower part of the wooden crate 1 is dropped in the opening of the talc 10 and the field plate 11 The wooden crate 1 is finished so that it can be easily dropped without sliding off the roof. The rest is good if you just screw it in with nails.
Double insulation chimney 6 is filled with high-performance insulation silica and rock wool, and is manufactured as double insulation chimney 6.
The ceiling partition plate 8 is made of metal and is fastened with screws or nails 17 so that the inside of the through portion can always be inspected.

For the cap-type flushing 2, we paid great attention to the rain and made a structure that would not leak rain. The polite installer will put the sealing 9 in the water return 13 part. And more polite installers can also add an L-shaped drainer to the flared portion of the cap-type flushing 2 to make it more perfect.

A double insulated chimney 6 is connected immediately above the cap-type flashing 2 14 A double insulated chimney fitted with a fixed storm collar 4-1 by laser welding etc. 19 is connected about 50 mm to 70 mm above the connection 14 Then, it is assumed that the rear storm collar 4 is attached immediately above the connection band 14 (lower stage), and the sealing treatment 9 is performed here.
The double insulated chimney 6 is fixed to the gantry 1 by the fixing bracket 3.

Therefore, compared to the general (conventional) flushing, because the stand 1 is attached, the drainer 5 is started up greatly, so the rain finish is improved, and by using the cap type flushing 2, the rain finish is very heavy. became much better.
The storm color is also in two stages, and the upper part is laser welded 19 directly on the double insulated chimney 6, so this also seems to improve the rain performance.

Example 1
FIG. 1 is a diagram for exhausting smoke from stoves and combustion products according to the first embodiment of the present invention. A stand 1 is attached to the roof portion, and a stand is provided. The heavy insulated chimney 6 is further fixed with the fixing bracket 3.
It is assumed that the fixture 3 is fixed so that the connection 14 of the double chimney 6 comes immediately above the cap-type flashing 2.
Connection of roof and building in the flue, installation of an integrated large drainer 5 to ensure the rain finish in fixing, and fixing to the wooden crate 1 with screws etc. from the side By fixing the flushing 2 to the wooden crate 1 from the side of the drainer 5, it is now confirmed that the rain will surely be carried out.
First, a connection 14 of a double insulation chimney 6 is provided immediately above the flushing 2 with a roof-gradient-type frame, and a storm collar 4-1 fixed by laser welding or the like 19 is attached about 50 mm to 70 mm from the connection. Connect a double insulated chimney, connect with connection 14, attach a storm collar 4 on the back just above the connection band 14 and seal treatment 9 here, it will be more rainy The
7 The inside of the penetration part has a non-combustible finish.
The ceiling partition plate 8 (metal plate) is fastened with screws or nails 17 so that the penetration part can be inspected from below the ceiling so that it can always be inspected.
Double insulation chimney 6 is packed with high performance insulation silica etc. and rock wool rock wool, so it provides a high insulation chimney with a roof gradient type frame that can propose a stove environment without worrying about fire This is a cap-type flushing structure with a roof gradient type gantry that can fully draw out the performance of the stove by the cap-type flushing 2.

Example 2
Next, a second embodiment of the present invention will be described. The indoor ceiling is not always a sloped ceiling. In the case of a horizontal ceiling, the double insulated chimney 6 is also lowered from the horizontal ceiling for construction work, and the ceiling partition plate 8 should be prepared with a horizontal object. To do.
The horizontal partition plate 8 is also constructed in a state where it is possible to inspect the inside of the flushing structure with a roof gradient type frame at any time.
The chimneys around the ceiling will be finished with non-combustible materials.
Then, underneath the double insulated chimney 6 that is below the horizontal ceiling, a single chimney 16 will be installed to dissipate warm air throughout the house.
Up to now, both Example 1 and Example 2 were considered as construction work only by a specialist specialized in stoves, but when using the newly developed cap type flushing structure with a roof gradient type frame, Cap work flushing structure with a roof gradient type gantry, which can be installed even by a woodworking contractor (carpenter) such as a sheet metal builder involved in construction work, with a gantry immediately after the upper wing or at the upper wing, and a dedicated drainer Since the body is constructed, the tile construction company and the roof construction company can construct the roof work quickly, and the roof construction with good rain can be done.
Chimney construction can also be carried out independently of roof construction, and it has become more rational and economical than previously thought.
The roofing contractor also took about 1 or 2 days for the construction around the chimney, but it took about half a day, making the construction work much easier.
Also, by removing the roof, the chimney maintenance becomes very easy. That is why ignition and combustion will be smooth, and if the roof is removed, the flame will be used for the draft effect. It sucks as well as it is, and it goes to the point where it burns very quickly.
Until now, it took about 35 to 40 minutes for the stove body to reach 200 degrees, but if it is roofed, it takes about 20 minutes to reach 200 degrees. When it burns in, black smoke is emitted during that time, unburned material (black smoke) continues for a long time, and it adheres to the inside of the chimney. The repetition is related to chimney cleaning.
What can be thought of is that roofing is also the best way to bring out the performance of wood burning stoves.
Chimney cleaning will be completed in one season, and it will only be necessary to clean up at the end.
However, if you use a non-ginger or non-clean burning stove, it may be cleaned monthly.
For this reason, it is important to use the cap-type flushing structure with a roof-gradient frame that has a good roofing structure and is well suited to rain.
Using this product can be said to be an economical construction method that is very rational in terms of construction method and subsequent maintenance.
Stove construction work so far, the first opening after the upper wing, opening around and making the surroundings incombustible, fixing the double insulated chimney to the field board,
After that, the roof construction worker was holding only the flashing while doing the construction.
2nd external chimney finish after roof construction
Near the completion of the 3rd time, the stove body and chimney connection and test burning have been carried out.
When installing this development product, when installing and installing this cap type flushing structure with a roof gradient type frame,
1st frame installation and draining installation
External chimney construction completed and flushing construction completed
Near the completion of the second time (last), stove body and chimney connection and test burning
In the future, the first construction will be performed by a roofing contractor or woodworker (carpenter) instead.
I think that you can ask.
As a stove contractor, it is considered that only the second (last) work is required.
Reduce the complexity and time-consuming and high-tech work.
Providing a flushing structure that can reduce the construction time and greatly shorten the process by bringing it into the roof construction process is a very rational and economical construction method.
