1984年起,我公司采用远红外加热管(内热法)养护混凝土,这种方法设备简单,操作方便,升温速度快,养护周期短,费用低,是一种较理想的混凝土冬期养护法。一、电热管的埋设 1.埋设方法在钢筋绑扎前,根据构件的截面尺寸和热工计算确定电热管的排列位置。采用木模板时,用木钻在梁、柱的两侧钻φ25mm孔,待钢筋绑扎完毕后在孔内穿入3/4英寸薄壁铁管,其两端可超出模板1cm。 2.电热管的排列电热管的排列可根据构件的截面尺寸和
Since 1984, our company has adopted far-infrared heating tubes (internal heat method) to preserve concrete. This method is simple and easy to operate, has a fast heating speed, short maintenance cycle, and low cost. It is an ideal method for concrete winter maintenance. First, the embedding of electric heating tube 1. Before laying the reinforcing steel bar, according to the size of the member and the thermal calculation to determine the arrangement of the heating pipe. When using a wooden formwork, use a wooden drill to drill φ25mm holes on both sides of the beam and column. After the reinforcements are tied, 3/4 inch thin-walled iron pipes are drilled in the holes, and the two ends can exceed the template by 1cm. 2. Arrangement of electric heat pipes The arrangement of electric heat pipes can be based on the cross-sectional dimensions of the components and
