Roof connected with steel frame beam through Z-shaped steel purlines and construction method of roof

DONG YOU / YANG ZIYE / FAN ZHICHAO

The invention relates to a roof adopting Z-shaped steel purline and steel frame beam connection and a construction method of the roof adopting Z-shaped steel purline and steel frame beam connection, which comprises a steel frame beam, angle steel purline supports and Z-shaped steel purlines, and is characterized in that the steel frame beam is made of H-shaped Q235 steel; the angle steel purlin holder is made of L-shaped Q235 steel; four mounting holes are uniformly distributed in a long flange of the angle steel purlin holder and are used for connecting the Z-shaped steel purlins; the angle steel purlin holder is welded on the steel frame beam; an upper hole and a lower hole are formed in the end part of the Z-shaped steel purlin, and the distance between the two holes is equal to the distance between the upper hole and the lower hole of the long flange of the angle steel purlin support; by additionally arranging the steel frame beams, the angle steel purlin supports and the Z-shaped steel purlins, the overall strength and durability of the roof are improved.

本发明涉及屋顶采用Z型钢檩条与钢架梁连接及其施工方法，包括钢架梁、角钢檩托和Z型钢檩条，其特征在于：所述的钢架梁为H型Q235钢；所述的角钢檩托为L型Q235钢；所述的角钢檩托长翼缘上均匀分布四个安装孔，用于Z型钢檩条之间的连接；所述的角钢檩托焊接在钢架梁上；所述的Z型钢檩条端部有上下两个孔，两个孔间距同角钢檩托长翼缘的上下孔间距；通过新增钢架梁、角钢檩托和Z型钢檩条，从而提高屋顶整体的强度和耐久性。
