水泥门窗框具有取材容易,价格便宜,不腐烂变形等优点,可节省大量木材,在农村已逐步推广应用。但由于一般采用木模手工捣制成型,外观质量较差,在运输、安装中易出现裂缝,且小五金未能妥善固定,从而影响进一步推广。为了提高水泥门窗框的质量,改善使用性能,我院与扬州建筑材料构件三厂协作,开展了水泥门窗框成型机具和预埋件的研制工作,已于1984年4月通过了技术鉴定。成型机具的各项技术参数和性
The cement door and window frame has the advantages of easy material acquisition, low price, no rot deformation, etc., which can save a large amount of wood, and has been gradually applied in rural areas. However, due to the fact that wood molds are generally used for hand-made molding, the appearance quality is poor, and cracks easily occur during transportation and installation, and the hardware is not properly fixed, which affects the further promotion. In order to improve the quality of cement door and window frames and improve its performance, our institute cooperated with the third factory of building materials in Yangzhou to carry out the development of cement door and window frame forming machines and embedded parts. It passed the technical appraisal in April 1984. All kinds of technical parameters and properties of molding machines
