膠合板is used extensively in the building trades, so carpenters to cabinetmakers to home improvement enthusiasts alike should recognize the standard sizes it comes in. A standard sheet is 4 by 8 feet and can be found in a series of thicknesses, with specialized sizes likewise offered for crafting projects or large construction jobs.

尺寸公差
膠合板由薄薄的軟木製成，在層中粘在一起，用木紋的每層垂直於下一個。其尺寸公差 - 特別是對於厚度 - 小於建築業交易中使用的公用級膠合板。公用事業膠合板的耐受性為1/32英寸，而櫥櫃膠合板為1/64英寸。
Actual and Nominal Thicknesses
The nominal (stated) thicknesses of plywood varies from 1/8 inch (3.2 mm) to 1 1/4 inches, which is comparable to 31.75 mm. Therefore, a sheet of plywood with a stated thickness of 3/8 inch is, in fact, 11/32 inches thick.
了解膠合板大小
當您購買膠合板時，您將想考慮不僅僅是眾多分級類別;您還需要知道尺寸是什麼意思。在一個大型家用改善中心購物可能會導致您認為這是一種簡單的事情，即用所需的厚度選擇4 x 8張，但它並不容易 - 特別是如果您到專門的伐木工人或木工商店。
厚度
必須認識到所列厚度是標稱尺寸，而不是真實測量是至關重要的。就像建築工木材一樣，所說的尺寸因真實測量而異，膠合板表項的完全相同：
陳述與實際尺寸
- 1/4英寸等於11/32英寸
- 1/2英寸等於15/32英寸
- 5/8-inch equals 19/32-inch
- 3/4-inch equals 23/32-inch
Specialized woodworking stores might stock plywood in extra thicknesses.
If someone is creating a bookshelf in which a “3/4-inch” plywood rack is positioned into a dado slot cut with a 3/4-inch router bit, there will be a really obvious 1/32-inch space, and the rack will feel a bit loose in the dado. All great cabinets and woodworking tasks require taking into account the distinctions between real and stated measurements of the boards.
Lots of sellers now identify plywood items with the real thicknesses, along with the nominal thicknesses just to ensure consumers know what they are purchasing.
膠合板床單的尺寸
大型箱子通常為硬木麵孔或打磨的鬆樹提供理想的，用於4 x 8英尺的床單中的木工任務。它們可能同樣提供“項目麵板”件，測量2 x 2英尺或2 x 4英尺。這些工作麵板通常由商店從大麵板切割到大小的大小，以滿足區域需求。
專業的木工商店經常提供一係列硬木麵板。波羅的海樺樹（包括樺木貼麵）的膠合板）經常進入5 x 5英尺的麵板。
為什麼標稱大小不同於實際尺寸？
所述尺寸與其真實尺寸之間的區別是由於其平麵和幹燥的原因，這減少了從最初磨碎的測量結果中的測量結果。例如，一個鬆樹板首先被壓碎於精確的2×4英寸測量，但隨後的刨料和幹燥過程將電路板縮小約半英寸。
With wood boards offered in stores, the distinction in real vs. stated measurements is generally about 1/16 inch. When utilizing strong woods in their projects, woodworkers have to keep this in mind.
使用膠合板物品，實際和規定的厚度之間的區別是由於在所有層實際粘在一起並幹燥後完成麵板臉部的打磨程序。這種打磨通常消除了電路板的約1/32英寸。
使用膠合板的提示
使用膠合板不斷經驗。膠合板床單的大小使它們難以在一個小型工作室管理。處理大膠合板的大床單將更容易利用這些標準技術，用於精確設計，切割和裝配。
Keep in mind that if you are using the larger, utility-grade plywood, you’ll need more framing to keep it sturdy. Larger plywood panels are more susceptible to cracking and breaking than shorter boards. Keep the spaces between studs or rafters narrow to ensure the plywood doesn’t sag or become vulnerable to the weight it’s meant to bear.
準確布局
在討論您需要做的內容之前要切割精確的膠合板，您需要將膠合板床單放入工作室或車庫中。切割精確的部件，特別是從片產品外，以強大的結構開頭。在這裏，該結構包括精確的設計線。
The easiest type of design that you can utilize with big sheets is to merely make numerous marks all along your sheet. You can line up a woodworking ruler or a straightedge with a set of the marks and draw the lines with your pencil or marker.
光滑，精確的削減
After determining and identifying your lines, you’re now ready making precise cuts for matching those lines. When working with a smaller sheet, using a table saw is the fastest method to cut pieces to size. For larger sheets, you’ll want to use a track saw. Jigsaws are best for curves.
集會
隨著項目的所有碎片出發並妥善削減，您都設置為完成任務完成。你的精確切割碎片贏得了意義的事情，但是，如果你粘上你的碎片歪曲。
When you’re ready to assemble your project, you first need to choose your glue. For most projects with plywood, you’re going to have multiple pieces to assemble, and they’re often large. For simpler assemblies, Titebond II works well.
最後，確保您擁有所有夾具，您需要安全地保持碎片。在牢牢方向角落後，繼續沿著你的關節夾緊夾緊，使某些區域被拉緊。不要太緊，無法避免翹曲麵板。
Now you can drive in your screws if your project requires it. Despite the fact that the screws protect the joints, I’ll often let the clamps stay on for a number of hours to ensure an excellent bond.
