建筑问题:山坡上的小盒子

格雷戈里·哈维尔(Gregory Havel)

A song written by Malvina Reynolds in 1962 became a hit for Pete Seeger in 1963. *The first verse follows:

山坡上的小盒子
Little boxes made of ticky-tacky,
Little boxes, little boxes,
Little boxes, all the same.
有一个绿色和一个粉红色
还有一个蓝色的和黄色的
And they’re all made out of ticky-tacky
And they all look just the same.

这首歌是对1940年代后期和1950年代建造的住房发展的评论,以容纳第二次世界大战和朝鲜战争的退伍军人,他们已婚,需要房屋来养家。这些开发项目中有许多相同的房屋具有相同的平面图(照片1),并由最便宜的材料制成。通常,唯一的变体是油漆颜色。

Several fire service authors have suggested becoming familiar with these neighborhoods and model homes. If search and rescue or interior fire attack was needed, there was little possibility of firefighters becoming disoriented because all of the houses on a street had the same layout. A typical layout might be the following:

  • Through the front door is the living room, with the stairway to the second floor on the left and the stairway to the basement stairway below it;
  • 厨房和用餐区直接前进。
  • 浴室位于楼梯顶部的二楼。和
  • bedrooms on either side.

这是一个很好的建议,在过去的50年中为消防服务提供了很好的建议。但是,您必须记住,按照今天的标准,这些房屋很小。今天的这些房屋已有60至70年的历史。他们中的许多人都有增加,其中大多数至少进行了一次重塑。

Even though these houses were built cheaply, they were platform-framed using sawn lumber joists and studs. At that time, sawn lumber was likely to be full-dimension unplanned wood. Planed lumber was also available; a 2 × 4 actually measured 1.625 inches × 3.625 inches. Plywood was the only commonly used form of manufactured lumber. This is the “legacy” construction that Underwriters Laboratories and National Institute of Standards and Technology has used in fire comparison tests with several types of lightweight construction methods using manufactured wood materials. Although many of these houses were finished on the inside with gypsum drywall board, some used lath and plaster.

The additions to the original construction and remodeling are likely to have used I-joists, wood trusses, plywood, oriented strand board, sheet metal joist hangers, laminated veneer lumber and 2 × 4 lumber measuring 1½ × 3½ inches.

We can no longer depend on the identical layouts in houses in these neighborhoods as we did in the past; and we can no longer assume the patterns of fire behavior from house to house. A fire in an addition is likely to behave differently that a fire in the original part of the structure; and remodeled areas supported by modern lightweight materials and construction methods are likely to collapse more quickly than the original structure.

Although it is possible that some of these houses are unchanged from the day when they were built, it is more likely that there have been significant changes. Perhaps the stairway to the second floor was moved into an addition, and the stairway opening closed with lightweight construction materials (photo 2).

For their own safety, firefighters responding to one of these homes must assume that it has changed since it was built, and that lightweight construction materials have been substituted somewhere inside.
