摘要

TLDRDenne video gennemgår tre metoder til at hænge rektangulære luftkanaler op i loft, på loftet eller i en kravleplads. Første metode indebærer placering af S-locks og brug af skulder som støtte til kanalen. Anden metode involverer at hænge en sekundær kanal på forhånd for at lette installation. Den tredje metode består i at samle flere sektioner af kanalen på jorden og derefter hænge dem samlet. Det er også vigtigt at forsegle kanalerne med mastic for at forhindre lufttab. Videoen giver detaljerede instruktioner om, hvordan man bruger bærebeslag og skruer korrekt for at sikre holdbarhed. Der diskuteres også sikkerhed og forebyggelse af nedfald af kanaler. Hvis der er behov for isolering, anbefales det at tilføje det efter påføring af mastik og før ophængning.

    Crammy Glacio fra AEC Surface Tech præsenterer tre metoder til at hænge rektangulære kanaler i loftet, et loftsrum eller et kravlerum. Først viser han de målte dimensioner af kanalerne og drive hangers (11 og en kvart tommer). Derefter demonstrerer han, hvordan man hurtigt laver en drive cleat, inklusiv bøjningsprocessen ved hjælp af håndbremser. Han understreger sikkerheden ved at lave huller i cleat ved at bruge enten en ridseprik eller en lynskrue og den foretrukne brug af galvaniserede deckscrews for at sikre holdbarhed i våde områder.

视频问答

  • Hvad er den mest almindelige metode til at hænge luftkanaler?

    Den mest almindelige metode er at placere S-locks på den eksisterende kanal på forhånd og derefter bruge skulderen som støtte til at løfte og justere den nye kanal på plads.

  • Hvilken type skruer anbefales til at sikre kanalophæng?

    Det anbefales at bruge galvaniserede decks-kruer, da de er modstandsdygtige over for korrosion og derfor holder længere.

  • Hvordan kan man forhindre lufttab i kanalerne?

    Efter installationen bør kanalerne forsegles med mastic for at forhindre lufttab.

  • Hvornår bør man tilføje isolering til luftkanaler?

    Isolering bør tilføjes efter påføring af mastik og før ophængning, især hvis kanalerne hænges i uopvarmede områder.

  • Hvordan kan man håndtere en stram installation?

    Hvis pladsen er begrænset, kan man præ-hænge kanalen og lade den svinge for lettere at fastgøre S-locks. Man kan også trimme kanterne af kanalen for bedre pasform.

    this is crammy glacio from aec surface
  • 00:00:02
    tech and today what we're going over are
  • 00:00:03
    three methods in order to connect and
  • 00:00:05
    hang rectangular duct in a ceiling an
  • 00:00:08
    attic or in a crawl space
  • 00:00:13
    [Music]
  • 00:00:17
    so here we have 14 by eight rectangular
  • 00:00:20
    duct and you can see it actually
  • 00:00:21
    measures fourteen and a quarter inches
  • 00:00:24
    and here it measures about eight and
  • 00:00:27
    eight eight and a quarter or so so
  • 00:00:29
    basically we have these pieces of drive
  • 00:00:32
    hangers cut so that you have nine and a
  • 00:00:34
    quarter plus one inch plus one inch so
  • 00:00:37
    it's 11 and a quarter inches and so
  • 00:00:39
    we're going to be hanging our next piece
  • 00:00:40
    over here
  • 00:00:42
    and we have 14 and a quarter inches
  • 00:00:44
    between each one of these two pieces of
  • 00:00:46
    hanging drive
  • 00:00:48
    and what i'm going to do next i'm going
  • 00:00:50
    to show you how to make these real quick
  • 00:00:51
    and then we're going to go ahead and
  • 00:00:52
    show our three methods for hanging it up
  • 00:00:54
    so after we have our drive cleat cut out
  • 00:00:57
    of our long piece which is a 10 foot
  • 00:00:59
    section these are cut at 11 and a
  • 00:01:01
    quarter inches
  • 00:01:02
    what we do next is we take our hand
  • 00:01:04
    brakes and we have these little notches
  • 00:01:07
    on the handbrakes that's a quarter inch
  • 00:01:09
    half inch three quarter one inch so we
  • 00:01:11
    have it set at one inch right now and
  • 00:01:13
    we're just going to fold this over just
  • 00:01:15
    like this now you could leave the bottom
  • 00:01:17
    and fold that over after you hang the
  • 00:01:18
    duct or we could go ahead and and do
  • 00:01:21
    that as well
  • 00:01:22
    the big thing right now is when we're
  • 00:01:24
    putting these holes in depending on how
  • 00:01:26
    you put these holes this thing can spin
  • 00:01:28
    around and you want to be safe and not
  • 00:01:29
    try to cut yourself so
  • 00:01:31
    what i end up doing a lot of times is
  • 00:01:33
    i'll take a scratch aw and i'll just
  • 00:01:35
    punch a hole
  • 00:01:40
    so you could do it that way or what you
  • 00:01:42
    could do
  • 00:01:44
    is you could take a zip screw uh with a
  • 00:01:46
    drill bit on it in order to get your
  • 00:01:48
    second hole
  • 00:01:52
    so you could do it that way so either
  • 00:01:54
    way is good and we're going to be using
  • 00:01:56
    deck screws for this in order to mount
  • 00:01:58
    them into uh the joists i use two
  • 00:02:01
    galvanized deck screws because i know
  • 00:02:02
    they're not going to rot over time and
  • 00:02:04
    they're not going to fall out i've seen
  • 00:02:05
    enough ducts
  • 00:02:06
    actually fallen down the whole entire
  • 00:02:08
    duct falling down just because there's
  • 00:02:10
    one roofing nail that was nailed through
  • 00:02:12
    the bottom of this into the floor joist
  • 00:02:14
    and that's just pulled down over time
  • 00:02:15
    due to that wet crawl space
  • 00:02:18
    [Music]
  • 00:02:42
    [Music]
  • 00:02:52
    in this case the lip of the duct that's
  • 00:02:54
    going to come in is going to go inside
  • 00:02:56
    of this duct because you can see the lip
  • 00:02:58
    for this existing duct is right here in
  • 00:03:00
    the s-lock so this is what it looks like
  • 00:03:02
    right here
  • 00:03:03
    and same thing up here we have our lip
  • 00:03:06
    where we're going to be putting our
  • 00:03:08
    other piece is going to go above this
  • 00:03:10
    existing duct right here and so now
  • 00:03:13
    we're going to go ahead and get to
  • 00:03:14
    method one so for method one which is
  • 00:03:16
    the most common duct hanging method
  • 00:03:18
    we're going to put both of our pieces of
  • 00:03:19
    s-lock on our existing duct ahead of
  • 00:03:21
    time
  • 00:03:22
    and so these pieces of s-lock they're
  • 00:03:24
    also referred to as slip and slide are
  • 00:03:26
    cut to about 1 8 of an inch smaller than
  • 00:03:28
    the inside dimension of the duct
  • 00:03:30
    and you can see that both s locks are
  • 00:03:32
    facing the same direction so our new
  • 00:03:34
    duct is going to be coming right in uh
  • 00:03:36
    to the top section right here so method
  • 00:03:39
    one we're going to take our duct
  • 00:03:42
    and we're going to rest it on our
  • 00:03:43
    shoulder just like this we're going to
  • 00:03:44
    get this side lined up first so we're
  • 00:03:46
    going to kind of come at an angle like
  • 00:03:47
    this i have my hand on the ear right
  • 00:03:50
    here on purpose just to try to line it
  • 00:03:52
    up into that top s lock as well
  • 00:03:55
    we're going to take our drive while
  • 00:03:57
    we're holding this duct up with our left
  • 00:03:58
    hand and we're going to slide that up
  • 00:04:01
    just like that now we're going to take
  • 00:04:03
    this stuff and we're going to wiggle it
  • 00:04:06
    so it's all the way back like that
  • 00:04:08
    and then we're going to pull it like
  • 00:04:10
    this
  • 00:04:11
    so when we pull it like that it should
  • 00:04:12
    tighten the ears
  • 00:04:14
    in the back
  • 00:04:18
    just like that
  • 00:04:26
    then we can fold these over
  • 00:04:32
    next we're going to get our drill and
  • 00:04:34
    secure these
  • 00:04:35
    so now that we're we're here since these
  • 00:04:38
    pieces of drive were already pre-bent
  • 00:04:40
    we're just going to put one zip screw
  • 00:04:42
    right in the bottom here one here
  • 00:04:44
    and then we're going to fold these over
  • 00:04:48
    and we can put two screws in these so we
  • 00:04:50
    can either put two in the bottom or one
  • 00:04:52
    in the bottom and one in the middle
  • 00:04:54
    after putting your zip screws into the
  • 00:04:56
    drive in order to hold the duct you
  • 00:04:57
    would then take your mastic
  • 00:04:59
    in order to seal up your duct so you
  • 00:05:01
    don't have any air loss now we're going
  • 00:05:03
    to move on to method number two
  • 00:05:05
    method number two includes pre-hanging
  • 00:05:07
    this secondary duct right here and
  • 00:05:09
    you're only going to put the screws on
  • 00:05:10
    the bottom
  • 00:05:12
    of the hanging drive cleats and this
  • 00:05:13
    allows the duct to pivot back and forth
  • 00:05:16
    in order for you to put your s lock it
  • 00:05:19
    now you may need to do this if you have
  • 00:05:21
    a
  • 00:05:22
    hard position that this duct is in or
  • 00:05:23
    you have a long section of duct and you
  • 00:05:25
    can't hold it up in the air
  • 00:05:45
    now another thing in reference to this
  • 00:05:47
    if you're kind of stuck in a position
  • 00:05:48
    where you you can't go back and forth
  • 00:05:50
    with this duck and it's just tight right
  • 00:05:52
    here what you could do is you could take
  • 00:05:54
    your tin snips
  • 00:05:55
    in order to cut
  • 00:05:58
    like right here a half inch this way and
  • 00:06:00
    you can take your
  • 00:06:01
    other 10 snips and come this way and cut
  • 00:06:03
    a half inch and that will give you the
  • 00:06:05
    gap in order to basically hit on your
  • 00:06:08
    s-lock and you can you can hit it all
  • 00:06:09
    the way in same thing with the top and
  • 00:06:11
    then you can go ahead and put your your
  • 00:06:13
    drive in place for
  • 00:06:14
    a tight situation
  • 00:06:20
    [Music]
  • 00:06:31
    [Music]
  • 00:06:32
    so method number three is attaching
  • 00:06:36
    multiple lengths of duct work on the
  • 00:06:37
    ground and putting them together we're
  • 00:06:39
    going to be screwing them together you
  • 00:06:40
    take a long zip screw in order to do
  • 00:06:42
    that so the s-lock doesn't bend open
  • 00:06:45
    and then we're going to
  • 00:06:47
    mastic this together you could do as
  • 00:06:49
    many as even like say 24 foot of duct
  • 00:06:51
    work and just hang the whole section
  • 00:06:53
    together with two or three texts this
  • 00:06:55
    way it avoids you having to do this one
  • 00:06:58
    little section at a time so now we're
  • 00:07:00
    going to go ahead and add our mask to
  • 00:07:02
    this while it's on the ground so we can
  • 00:07:03
    get everything very easily at this point
  • 00:07:06
    we would also cut any colors in that we
  • 00:07:08
    need and we would seal them up against
  • 00:07:10
    the duck with the mastic
  • 00:07:27
    we're going to continue adding mastic to
  • 00:07:29
    this and then we're gonna hang our duck
  • 00:07:34
    [Music]
  • 00:08:02
    now that we have this all masticed up
  • 00:08:03
    and we have our bottom section screwed
  • 00:08:06
    i'm going to have brandon help me lift
  • 00:08:07
    all these sections of duct up at one
  • 00:08:09
    time and we're going to go ahead and
  • 00:08:10
    hang them in place
  • 00:08:19
    you got it thanks
  • 00:08:22
    [Music]
  • 00:08:43
    so
  • 00:08:47
    [Music]
  • 00:09:00
    all right good to go
  • 00:09:02
    we hung this duck without insulation but
  • 00:09:04
    if you were going to add insulation
  • 00:09:05
    because you're hanging in the duct in a
  • 00:09:07
    non-conditioned area you would add the
  • 00:09:09
    insulation after the mastic and have it
  • 00:09:11
    all taped and secured ahead of time
  • 00:09:12
    before you hang the duct so i hope this
  • 00:09:14
    video helped you understand multiple
  • 00:09:16
    methods in order to hang ductwork and
  • 00:09:18
    the different techniques in which you
  • 00:09:20
    could use and the the methods for the
  • 00:09:22
    the drive and the slide and how many
  • 00:09:25
    screws to put in all that type of stuff
