15-4 PREFITTING AND MACHINING (PREMACHINING) DOORS
The doors may be machined at the factory to receive various types of hardware. Factory machining can prepare the door to receive cylindrical, tubular, mortise, unit, and rim locks. Other hardware such as finger pulls, door closers, flush catchers, and hinges (butts) are also provided for. Bevels are put on the doors, and any special requirements are handled.
Premachining is popular as it cuts job labor costs to a minimum, but coordination is important because the work is done at the factory from the hardware manufacturer’s templates. This means that approved shop drawings, hardware and door schedules, and the hardware manufacturer’s templates must be supplied to the door manufacturer.
From the estimator’s point of view, premachining takes an item that is difficult to estimate and simplifies it considerably. Except where skilled door hangers are available, premachined doors offer cost control with maximum results. For this reason, they are being used more and more frequently.
15-5 PREFINISHING DOORS
Prefinishing of doors is the process of applying the desired finish on the door at the factory instead of finishing the work on the job. Doors that are premachined are often prefinished as well. Various coatings are available including varnishes, lacquer, vinyl, and polyester films (for wood doors). Pigments and tints are sometimes added to achieve the desired visual effect. Metal doors may be prefinished with baked-on enamel or vinyl-clad finishes. Prefinishing can save considerable job-finishing time and generally yields a better result than job finishing. Doors that are prefinished should also be premachined so that they will mot have to be “worked on” on the job. The prefinished door must be handled carefully and installed at the end of the job so that the finish will not be damaged; it is often difficult to repair a damaged finish. Care during handling and storage is also requisite.
参考答案:15-4 PREFITTING 和用机器制造的(PREMACHINING) 门 门也许用机器制造在工厂接受各种各样的类型硬件。工厂用机器制造可能准备门接受圆柱形, 筒形, 榫眼、单位, 和外缘锁。其它硬件譬如手指拉扯, 门closers 、充足的俘获器, 和铰链(靶垛) 并且被提供为。斜面把放在门上, 并且所有特别要求被处理。 Premachining 普遍因为它减少工作人工成本对极小值, 但协调重要因为工作被完成在工厂从硬件制造商的模板。这意味着, 批准购物图画、硬件和门日程表, 并且硬件制造商的模板必须被提供给门制造商。 从估计物的观点, premachining 采取难估计的项目并且可观地简化它。除了熟练的地方门挂衣架是可利用的, premachined 门提议成本控制以最大结果。因此, 他们越来越频繁地被使用。 15-5 PREFINISHING 门 门Prefinishing 是申请渴望的结束的过程在门在工厂而不是完成在工作的工作。是的门premachined 经常prefinished 。各种各样的涂层是可利用的包括油漆、亮漆、乙烯基, 和聚酯薄膜(为木门) 。颜料和色彩有时增加达到渴望的视觉效果。金属门也许是prefinished 以烘烤在搪瓷或乙烯基穿的结束。Prefinishing 可能节省可观的工作精整时间和一般产生一个更好的结果比工作精整。prefinished 的门应该并且是premachined 以便他们意志mot 必须"工作在" 在工作。prefinished 门必须仔细地被处理和被安装在工作的结尾以便结束不会被损坏; 它经常难修理损坏的结束。关心在处理和存贮期间并且是必需品。
