常見的彩鋼板屋面的主要形式有：直立鎖邊型、角馳型、卡口型、明釘型等。鋼結(jié)構(gòu)廠房屋面的加固方式主要有加大構(gòu)件截面法和增加支點(diǎn)加固法。

鋼梁鋼檁條屋面結(jié)構(gòu)的鋼梁加固，主要為在鋼梁下增設(shè)T型鋼或C型鋼，用以增加鋼梁截面，提高承載力。鋼檁條加固方式一般在檁條兩端加設(shè)支撐

點(diǎn)，減少檁條跨度以增加檁條的承載力。對(duì)于彩鋼板屋面的加固，比較適用的方法：增加型鋼。因?yàn)樵趯?shí)施中存在焊接工序，一般要求在施工時(shí)地

The main forms of the common color steel plate roof are: vertical lock edge type, Angle gallop type, bayonet type, bright nail type, etc. The reinforcement

method of steel structure workshop roof mainly includes the method of increasing component section and increasing fulcrum reinforcement. The

reinforcement of the steel beam of the steel purlin roof structure is mainly for adding T-type steel or C-type steel under the steel beam to increase the section

of the steel beam and improve the bearing capacity. Steel purlin reinforcement is generally added with support points at both ends of the purlin to reduce the

span of the purlin to increase the bearing capacity of the purlin. For the reinforcement of color steel plate roof, the more applicable method: adding section

steel. Because there is a welding process in the implementation, it is generally required that there should be no production or stacking of flammable materials

on the ground during the construction.
