Types of building formwork
Keywords: building formwork
1. Divided by materials According to different materials, building formwork can be divided into wood formwork, steel-wood formwork, steel formwork, steel bamboo formwork, plywood formwork, plastic formwork, glass fiber reinforced plastic formwork, aluminum alloy formwork and so on. (1) The tree species of wood template are generally pine and fir. As a result of lumber consumption is larger, repeated utilization rate is low, to economize lumber, should use less or need not wood template as far as possible. (2) Steel-wood formwork is a type of formwork with Angle steel as the frame and wood as the panel. It can make full use of short wood and can be used for many times. (3) plywood template is a type of template with plywood as the panel and Angle steel as the frame. It has the advantages of high strength, small weight, no warping, no cracking and few seams. (4) The frame of steel bamboo formwork is Angle steel, and bamboo plywood is the panel. Its stiffness is large, not easy to deform, light weight, easy to operate. (5) steel formwork is generally made into a finalizing template, with connecting members assembled into a variety of shapes and sizes, suitable for a variety of structural forms. (6) plastic template, glass fiber reinforced plastic template, aluminum alloy template has the characteristics of light weight, large stiffness, convenient assembly, high turnover rate, but because of the high cost, has not been widely used in construction. |
