金属螺柱轨道布局和击落

一开始……

你是在工作中，蓝图，一堆铆钉和脚手架。下一步是什么？希望你有机会查看印刷品几天，以熟悉平面图，墙面，海拔和细节。当您看看他们的意图是什么时候，它更容易进入建筑师的头部。更好的是在开始之前访问该网站的机会。然而，经常访问该点的网站是不可能的，而且你几乎是“盲人”的网站。无论如何，您需要一个攻击计划。在您展开打印之前，请漫步网站并回答几个问题。空间是加法吗？你必须匹配现有材料吗？ 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

如果存在任何问题区域，请咨询您的一般主管。到了他应该知道的项目中的这一点。大多数人都愿意承认它，现在更容易且更好地纠正差异而不是等到他们在地毯或橱柜中出现。智能框架可以覆盖多种罪，这从布局开始。展开您的打印并尝试将图形定位为实际的建筑布局。这有助于避免“北/南，东/西”混乱。我喜欢用滚动的迷你脚手架作为桌子。在迷你脚手架上携带框架广场，额外的粉笔和50'和100'卷尺。如果它是Windy，你可以用它们按住你的图纸。寻找两个最长的外壁，尺寸被拉动为90度彼此。 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.

从平面图开始，把建筑师的尺寸加起来。一般条件应该告诉你尺寸是粗糙的还是精加工的。如果他们没有，那就查看打印上的开口和房间大小。如果它们是偶数，那么很可能是用完成尺寸绘制的。小心你的数学。糟糕的加法总是会导致问题。现在测量工作的整体尺寸。这些应该和指纹吻合。如果他们没有，寻找±符号。这样你就可以自由选择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.

一旦你对你的出发点感到满意，就开始你的布局。总是随身带着一把好的扫把，在用粉笔涂抹之前要扫每一个位置，以避免碎片影响线条。与你的助手保持一致(如果你有助手的话);沟通不畅是一个比糟糕的数学更普遍的问题。一定要减少变量。(我在整个构图过程中都是这么说的。)无论你是用胶带的尾端作为“零”还是切一英寸，都要保持一致。如果你的粉笔线错过了你的布局标记1/4英寸，扫线和再次打击。在布局上的错误会贯穿整个过程，然后通过我所说的“工作蠕变”而成长。完美的开始——你不会变得更好。 Don’t assume someone farther down the line will correct things. 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

布局完成后，开始考虑先挂哪面墙。当然，外墙、走廊墙和通高的墙需要在其余的分区之前建造，但试着像干墙衣架一样思考，为它们提供一个光滑的钉“路径”。我倾向于从左到右挂石膏板，所以我把我的角逆时针绕着房间转。这是右撇子悬挂器的自然过程。对于3-5/8 "墙，切割4-1/4 "到4-3/8 "的轨道内法兰的一端，将接收浮子或拍打螺柱。(不要切断和折叠法兰!这将突出过去的干墙和造成不必要的痛苦的地板工人。)将另一段轨道的末端放在这一段的顶部，这样外部凸缘就会接触到。你应该在里面有一个足够宽的缝隙，让石膏板滑进去而不绑定，但不是太宽，浮动螺柱掉出来。根据这条经验法则，优先选择你要击落的东西:首先是角落，然后是墙壁末端，然后是门边缘，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.

关于切割螺柱和轨道的一个词

您可以轻松切割20和25规格的干墙金属，剪排。有些人喜欢剪掉法兰，用公用事业刀得分，并“翼”来回轨道，直到它分开。这给了你一个漂亮的直边，但却是耗时的。我的首选方法是切割两个法兰，弯曲幅材，然后从点到点切割略微电弧“笑脸”。这是有效的，但它可以在很多切割的工作中产生很多手疲劳。在更大的工作岗位上，如果使用剁锯，了解燃烧镀锌金属的危险。有足够的通风。浓缩蒸气可以杀死你。另外，在操作剁锯时使用每次预防措施：有防护装置，确保库存，磨损眼睛保护，脱离叶片旋转的方式。

自信来自于能力。练习会让你变得更好。不要羞于检查你的工作。如果事情不正常，回头找问题所在。良好的布局和击落使工作。干脆，直线是一个伟大的名片!好运！
