随着我国经济建设的发展,木材供应日益紧张。国内对建筑木材的节约代用作了广泛的研究和探讨,其中革新门窗框就是节约木材的新途径之一。近几年来,内浇外砌施工工艺出现后,为以现浇混凝土门框代替木门框提供了有利条件。现浇混凝土门框的试制成功,彻底改革了传统木门框作法,减少了木材消耗。 With the development of our country’s economic construction, the supply of timber has become increasingly tense. The domestic saving of construction timber has been used as an extensive research and discussion. One of the new ways to save wood is the renovation of window frames. In recent years, after the construction technique of internal pouring exterior bricklaying has emerged, favorable conditions have been provided for the replacement of wooden door frames with cast-in-place concrete door frames. The successful trial production of cast-in-place concrete door frames has completely reformed traditional wooden door frame practices and reduced wood consumption.
