Description

[Detailed Description of the Invention] In addition, when a wall, tree, etc., such as a building or the like, is arranged in a J [-], the penetration point a = the path duct 1 = to be placed. .

Since the duct housing of the pass duct is made of metal sills such as MS, there is a possibility that the connection between the duct housing and the opening edge should be made at the penetration points of walls, floors, etc. %/& also specified to be fireproof and dust closed.

However, how about the bus duct & fittings?

:Pair of left and right cross-roads = shaped Il plate 1・'('
, -A''F!!Mze4: A horizontal MrIIJ abbreviation constructed by combining a pair of horizontal IM direction F-plates 2 and 2 with each folded fiber 1' and 2'! Shape data hacking 3
Circle C: encloses 41j of strip conductors 4 of several phases. i.e. anchor 1
Bad C: As shown, the # shape of the outer periphery of the duct housing 5 is complicated and vho, so when 411/opening of the floor, etc. - 65 = insertion arrangement, the opening between the opening edge and the duct housing 3 is closed i. Therefore, the outer part of the duct housing 6; the large carved shape of the partition plate 7 to be deposited, or the multi-shaft.

Ichinoseki C of the alignment part between the hole paper and the duct housing 3:
Filling #1 with sealing material 8 is troublesome.

As shown in Figure 112, 55: When filling both sides of the opening 6 with partition plates 7 and 7, the partition plates 7 and 7 and E= When filling with non-combustible material 9 such as Rotsu Takuru, it is necessary to block both sides of the opening 6 with partition plates 7 and 7. .

In the case where the sealing material is directly filled between the duct housing 5 and the opening edge without using a partition plate, it is possible to fill the seal material directly between the duct housing 5 and the opening edge.

It is easy to attach the partition plate 7.54 = The arc in Fig. 1: Divides the left and right halves 11; The partition a of the rim 41 is thin, so I processed it: (W, and the duct housing 3
It is unavoidable that the emblem should be completely attached to the outer part of the bottle, so it is unavoidable to attach the bottle to the outside.

Then, in the 19th century, due to the size of the partition plate 7, the length of the molded material 8 for the 7-ru material became longer, making it difficult to make the strips. Therefore, the finish of the closing treatment is likely to cause ff (: fi 1), and it is difficult to maintain a certain spinning effect and casting effect, and safety C: There is a problem.

The main point is the above-mentioned point -: the box, the above-mentioned cross-type pass duct - knitting is carried out in the building - the opening in the floor, etc. l1llI: the closing procedure for spinning and spinning when inserted and placed. To be able to do something is to be done.

In other words, bus ducts & ets are connected to openings 6 in buildings, floors, etc.
When inserting and arranging the opening 1164 of the duct housing 13 into the duct housing 13, the opening 1164 of the duct housing 13 is formed into a 7J shape, and its cross section is square in the length direction t of the duct housing 3. :WallI made the gist of the above-mentioned traversal as a means of forming anyis regrets.

Figure g3 and Figure 4 show parts 1m and 1m of both side plates 1 and 1 of the duct housing 3, respectively.

fll has a convex shape; another 111fiIB that has been bent and formed is fixed to each outer side I11α of both side plates 1-1 with a bathing stone, etc. 1. Dig the concave shape on the outside of the 12-1 side 111, and It forms part 3, and in this case also @l11 and iIl
Straighten the space between the material 1B: When you finish the material

In the example shown in FIG. 5 above, the convex bend 11ja of the side plate 1 is

Even when the sound is loud, the space &: above the conductor 4 between the two side plates 1 and 1 contains a certain amount 14I=subena 11.

The figure shows Iori Sada and 1 g in the case of close contact #insulated path duct.
! In the case of a gas-insulated type path duct, use
6 = Fireproof partition plate is installed in the right place in the door and %Ah.

The example in Fig. 6 shows that the outside of the duct housing 3 is assembled with the diagonal cylinder 12.
Part 6: Transverse-1 shaped part 3 formed by %U.

Kaku IIIi 11 Company 12 (Looking at the second generation, the steel plate outside mt = * of the duct housing 3 may be in the same layer.

And the space between -411 and corner 11s company 12 is a heat-resistant
Mll@re by filling with fireproof sealing material 13.

Even if the outside of the corner member 12-C: the partition plate 7 is stuck.

In Fig. 6 and Fig. 5, the outer periphery 5 of the transverse m-square part 3 m: the partition 17 is fixed in advance. If the screw is fixed, the connection with the duct housing 3 must be made of heat-resistant and fire-resistant material. 4. Opening s61 in the wall, floor, etc. 5 of the proboscis: inserted through the duct 8 to at least the above-mentioned duct 3;

The lengthwise direction of the duct housing 3 is closed by the rectangular cross section of 7. In order to close the connection between the inserted rear row 6 and the duct housing 5, the C 2 position is also divided into the partition I.
For i7, you only need to prepare a pair of U-shaped ones on the left and right, and the #-shaped one is simple and can be easily machined using a 66 to 90-degree V-rim board.

And the length 1 of the connection between the pair of T-shaped partitions horizontal 7 and the duct housing 5 and the duct housing 5 is the conventional abbreviation!屡横l
In the case of the duct housing of 11fwJ (: It is shorter than that, and the Ichinoseki is small e%A, so Ichinoseki 1;
It is easy to fill the opening ii and the duct housing 3t is small.
and 1, if the partition 417 is not used, and if it is possible to fill the cool material directly into the threshold, the opening of the duct housing 3 can be done by crossing the opening of the duct housing 3. r1m is 7
Since it is filled with J shape, it is easy to fill the V part with 6 and C:
The amount of parts used in the duct is small and it is clean, and the cross section of 2/3 of the duct is 1 fm, 7F model value is 5 m, or the length of the duct housing is 73 m.
・The opening 11161H of the floor, etc. 5 is inserted and the machining process of the head is 1g;
There are few differences between people, and the effect of preventing the spread of fire is certain.

When the cross section of the duct housing 3 is made of noncombustible material 1°/15, the noncombustible material 1°/15 is
Together with Mll & action, it acts as a material for the heat of the conductor, and the heat is released to the outside.

The outer circumference i of the transverse m rectangular part 3 m of the housing 5 of the non-axial bus duct unit: If the partition plate 7 is solidified in advance, 1
1. Opening of wood etc. 5 61: When the bus duct 1 is inserted and placed, insert it until the above partition fE7 reaches the wall/floor etc. This saves the trouble of making sure that the device is not inserted properly, and the work is easy. The role of a plumber is to raise and raise a horse, and to raise the head of the company.
The effect is 66°. Partition plate 7 is bell, floor, etc. 5 t=178
M Mlj or anchor gel, anchor pin, etc. 14≦
I can enjoy both of them.

Since the above-mentioned partition plate 7 is located outside the cross-sectional cedar part S of the data housing 3, it should be screwed in place. You can easily cool the material directly into the furnace with a knee opening.
Open the knit for the pass duct through the partition [7] [661:
