临街营业房在安装完铝合金地弹门的同时,从安全考虑,都要再安装相应于门洞口大小的钢制防盗门(或卷闸门),这样,每个营业门的洞口就要分别装上铝合金地弹门和钢制防盗门。为降低工程造价,又使营业房的房门具有防盗功能,我们对此进行了合二为一的组合。具体作法是:将铝合金门的框扇料全部不用(含配件),防盗门的框架改用壁厚2mm、60mm×30mm的方钢管制作。制作时先在靠外侧点焊15mm×2mm扁钢弯制组合的防盗花 While installing the aluminum alloy floor door in the street business room, from the safety considerations, the steel security door (or roll gate) corresponding to the size of the door opening must be installed. In this way, the opening of each business door must be installed separately. On the aluminum alloy floor door and steel security door. In order to reduce the project cost, and make the door of the business room have anti-theft function, we have made a combination of these two. The specific approach is: All aluminum alloy door frame fans (not including accessories), the security door frame is changed to a thickness of 2mm, 60mm × 30mm square steel pipe production. During the production, first weld the anti-theft flower on the outside by 15mm×2mm flat steel bending
