Древесина является самым древним строительным материалом. По сравнению со стальным брусом он легче, дешевле, проще в обработке, а его механические свойства хорошие. С другой стороны, древесина имеет определенные недостатки. Во-первых, он горит и поэтому не подходит для огнестойких зданий. Во-вторых, он разлагается.
Сеголня количество древесины используется для огромного числа целей. В строительстве также используется древесина.
Древесина - это название, применяемое к материалу, полученному из деревьев. Древесина, используемая для строительных целей, делится на две группы: хвойные и лиственные. Древесина лиственных пород используется главным образом в декоративных целях, например, для облицовки мебели, а некоторые из них выбраны для структурного использования из-за их высокой прочности и долговечности. В современном строительстве древесина часто используется для оконных и дверных рам, напольных покрытий, заборов и ворот, настенных панелей, для временных построек и неокрашенных внутренних деревянных конструкций.
Древесина не может быть использована ни для работы плотников, ни для столярных работ сразу же после ее вырубки из-за большого количества сока, который в ней содержится. Устранение этой влаги увеличивает прочность, долговечность и упругость древесины.
We decided to have a special celebration of Mother's Day. We thought it a fine idea. It made us realise how much Mother had done for us for years, and all the efforts and sacrifices that she had made for our sake. So we decided that we'd make it a great day, a holiday for all the family, and do everything we could to make Mother happy. Father decided to take a holiday from his office, so as to help in celebrating the day, and my sister Ann and I stayed home from college classes, and Mary and my brother Will stayed home from High School. It was our plan to make it a day just like Christmas or any big holiday, and so we decided to decorate the house with flowers. We asked Mother to do it, because she always does it. The two girls thought it would be a nice thing to dress in our best for such a big occasion, and so they both got new hats. Father had bought silk ties for himself and us boys. We were going to get Mother a new hat too, but it turned out that she liked her old hat better than a new one. After breakfast we decided that we would hire a motor car and take Mother for a beautiful drive away into the country. But on the very morning of the day we changed the plan a little bit. We all felt that it would be nicer to have a definite purpose. It turned out that Father had just got a new rod the day before, and he said that Mother could use it if she wanted to: in fact, he said it was practically for her, only Mother said she would rather watch him fish than fish herself. So we got everything arranged for the trip. Mother cut up some sandwiches and packed all up in a basket for us. When the car came to the door, it turned out that we couldn't all get in. Father said that he could stay at home and work in the garden. The girls said that Mother had only to say the word and they’d gladly stay t home and work. In the end it was decided that Mother would stay at home and have a lovely restful day round the house. It turned out anyway that Mother didn't care for fishing and also it was just a little bit cold and fresh out-of-doors, though it was lovely and sunny, and Father was afraid that Mother might take cold if she came. We had the loveliest day. Father and the boys fished, the girls met quite a lot of people. We all had a splendid time. It was quite late when we got back. We sat down to dinner. It was grand. When it was over all of us wanted to help clear the things up and wash the dishes, only Mother said that she would really much rather do it. When we all kissed Mother before going to bed, she said it had been the most wonderful day in her life and I think there were tears in her eyes.
