金属螺柱轨道布局和击落

在一开始的时候...

您是与蓝图，一堆螺柱和支架的工作。下一步是什么？希望你有机会到看打印几天来熟悉平面图，墙体剖面图，立面图和细节。它更容易获得建筑师的脑海里，当你看到他们的意图。更妙的是访问该网站，然后再开始的机会。在这一点上经常访问的网站是不可能的，但是，你在现场几乎到达“盲”。在任何情况下，你需要攻击计划。之前展开的版画，走现场，回答几个问题。是空间的增加？你必须匹配现有的材料？ Is it a new work out of the ground? Do you have multiple floors with framing that has to line up? How high is your deck? What does it consist of? Is the floor old concrete or new? Did the steel erection/masonry/concrete people do a good job (are things level, plumb, and square)? Are you under roof and dried in? Is there temporary power? Have you worked with this general contractor or these other sub contractors before? The answers to these questions affect how you proceed.

布局

问问你的总负责人是否有任何问题。到这个时候，他应该知道了。大多数人愿意承认这一点，而且现在纠正差异比等到它们出现在地毯上或橱柜上要容易得多，也更好。智能框架可以涵盖很多问题，首先是布局。展开你的印刷品，并尝试将图纸定位到实际的建筑布局。这有助于避免“北/南、东/西”的混淆。我喜欢用一个滚动的迷你脚手架作为桌子。携带你的框架正方形，额外的粉笔，和50'和100'的卷尺上你的迷你脚手架。如果刮风的话，你可以用它们来按住你的画。寻找两个最长的外壁，它们之间的维度是90度。 The longer the wall, the less likely it is out of square. These will be your reference lines. Check them for square. If you don’t have a convenient set of walls to use for reference, create your own lines. Find the center of each end of your project, chalk a center line, then chalk a 90 degree line off that. Use the largest 3:4:5 multiple you can. (A right triangle where the sides are in the ratio of 3:4:5 will give you a 90 degree angle every time.) Start with a line, mark the point you want to square, and make a second mark 4' down the line. Measure off your first mark approximately square to your line, sweeping a small arc at 3' with your pencil. Place your tape on the 4' mark and measure back 5' toward your arc. Sweep an arc at this measurement. The point where the two arcs intersect is square to your original mark. Any multiple of 3:4:5 (such as 6:8:10, 12:16:20, 30:40:50, etc.) will produce the same results. Use the largest multiple that is practical. Take care to "nail" the intersection point when striking the line.

按照你的方式在平面上工作，把建筑师的尺寸加起来。一般情况会告诉你尺寸是粗糙的还是光滑的。如果没有，那么看看打印上的开口和房间大小。如果它们是偶数，那么很可能打印与完成尺寸。小心你的数学。糟糕的添加总是会导致问题。现在测量工作的总体规模。这些应该和印花相配。如果没有，那就找±号。这将给你空间来决定墙壁的位置和房间的大小。 If the discrepancies are large, bring the Job Super in on it. He can pass the problem up the chain of command to get a decision. Next, it would not hurt to find out from which direction the plumbers and electricians pulled. It is easier for you to move your walls than for the plumber to move his pipes. This is the choice most Supers make, so save yourself time and money by clarifying these potential conflicts. Move a chalk line, not a wall.

一旦你满意你的出发点，开始布局。始终保持良好的细扫扫帚你，粉化，以避免碎片影响您的行之前席卷每面墙的位置。与您的帮助，如果你有一个在同一页上;沟通不畅是不是数学不好一个更普遍的问题。总是，总是降低你的变数。（我说这整个过程中取景。）无论您是使用磁带的末尾为“零”或切割一英寸，是一致的。如果你的粉笔线1/4” 想念你的布局标记，扫线，并再次罢工。在布局携带误区，一路过关斩将的过程，然后成长，通过我称之为“工作爬行”。开始完美的 - 你会不会变得更好。不要以为别人更远的路线会纠正的事情。 More likely, they will add their mistakes to yours and those mistakes will accumulate into sloppy, unacceptable work. Often, when chalking long walls, a third person will jump in and hold down the middle of the line with his finger, snapping each half. I discourage this because no matter how tight you pull your line (and it needs to be tight) unevenness in the floor often skews straightness. Pinning it down in the middle does not allow the line to self-correct when lifted before the snap. Just pull the line high and straight up, snap, and then have your helper do the same on the other end. Avoid lifting the line at an angle: that is the surest way to get a "double" line because the string will bounce on contact with the floor. I have found that marking and striking both sides of each wall is the best way to avoid "shoot-down" mistakes. If there is danger losing your lines, spray them with clear lacquer. I spray them lightly at the "crow’s feet" and will rechalk when shooting down track as necessary. How far you place door openings from inside corners is often spelled out on the prints; if not, try to leave your finisher enough room to get at least a 4” knife between the door frame and the adjacent wall. How wide you make door openings depends on the type of frame being used and how the door clips are attached. The rule of thumb for welded jambs is 2-1/8” X 2 plus the door width. So a 3’-0” door with welded jamb would require a 3’-4-1/4” opening. After-drywall knockdown frames typically need 1” past each side of the door, so a 3’-0” door with knockdown frame would require a 3’-2” opening.

跟踪

在布局完成后，首先开始考虑需要挂哪些墙。当然，外墙、走廊和全高度的墙需要在其他分区之前建好，但试着把它们想成一个干墙衣架，并为它们提供一个平滑的挂钩“路径”。我倾向于从左到右挂石膏板，所以我的角绕着房间逆时针旋转。这是右手衣架的自然进程。对于3-5/8 "墙，切断4-1/4 "到4-3/8 "的内部法兰的一端轨道，将接受浮动或拍击螺栓。(不要切断和折叠法兰出来!这会突出过干墙，给铺地板的人造成不必要的麻烦。)把另一块轨道的末端放在这一块的顶部，这样外部法兰接触。你应该在内部有一个足够宽的缝隙，以便石膏板在不绑定的情况下滑进去，但又不能太宽以至于浮动螺柱掉出来。根据这个经验法则，优先考虑你击落的东西:首先是角，然后是墙的末端，然后是门的边缘，然后是轨道末端，然后是其他所有东西。 For corners, line up both pieces of track on their marks and put firm pressure on the corner, taking care to not move the track, then shoot it down. I generally shoot my first pin about 2” off center in case it blows out. If it does, lift the track, brush out any debris, reset the track, and try again 2” away. One pin should hold both pieces down. Go to the other end of your track, shoot it down, and then fasten the rest of it. Some track will have a crown in it, so you might have to apply side pressure with your foot to align it to the chalk line. Some prints prescribe what fasteners you use and their spacing. As a general rule, 16” on center zigzagging as you go is enough for powder or gas loads. Small pieces of track can be hard to shoot down and keep aligned, so avoid using them near corners or doors unless you have to.

关于切割螺栓和轨道字

你可以用剪刀很容易地剪断20和25规格的石膏板。有些人喜欢剪断法兰，用一把实用刀在网上划痕，然后来回“折”轨道，直到它分开。这给你一个漂亮的直边，但是费时的。我最喜欢的方法是把两边的翻边都剪掉，把网折弯，然后点对点剪出一个微微弧线的“笑脸”。这是有效的，但它会在大量切割的工作中产生大量的手部疲劳。在较大的工作中，如果你使用的是锯，要了解燃烧的危险的金属镀锌。有足够的通风。浓缩的蒸汽可能会害死你。此外，操作锯时要采取一切预防措施:安装保护装置，固定刀架，佩戴护眼，并避免刀锋旋转。

自信伴随着能力。练习会让你变得更好。不要羞于检查你的工作。如果事情偏离正轨，回溯并找到问题所在。良好的布局和拍摄，使工作。挺括、笔直的线条是一个伟大的名片!好运！
