轻型钢结构有效的保证了刚架的平面外整体稳定性。若檩条或檩托板孔径过大过长，隅撑就失去了应有的作用。下面就来讲讲济南轻钢结构存在的质量问题及预防！

The light steel structure effectively guarantees the out of plane overall stability of the rigid frame. If the hole diameter of purlin or purlin supporting plate is too large and too long, the corner brace will lose its due role. Now let's talk about the quality problems and prevention of Jinan light steel structure!

隅撑角钢与钢梁的腹板直接连接，当刚架受侧向力时，使腹板在该处局部受到侧向水平力作用，容易导致钢梁局部侧向失稳。

The corner brace angle steel is directly connected with the web of the steel beam. When the rigid frame is subjected to lateral force, the web will be locally subjected to lateral horizontal force at this location, which is easy to cause local lateral instability of the steel beam.

有的工程所用檩条仅用电镀，造成工程尚未完工，檩条早已生锈。檩条宜采用热镀锌带钢压制而成的檩条，且保证一定的镀锌量。

Purlins used in some projects are only electroplated, resulting in that the project has not been completed and the purlins have already rusted. Purlins should be made of hot-dip galvanized strip steel, and a certain amount of galvanizing should be guaranteed.

因墙面开设门洞，擅自将柱间垂直支撑一端或两端移位。同一区隔的柱间支撑、屋面水平支撑与刚架形成纵向稳定体系，若随意移动其位置将会破坏其稳定体系。

One or both ends of the vertical support between columns shall be displaced without authorization due to the door opening on the wall. The column bracing, roof horizontal bracing and rigid frame of the same partition form a longitudinal stability system. If their positions are moved randomly, their stability system will be destroyed.

有些单位为了节省钢材和人工，将檩条和墙梁用钢板支托的侧向加劲肋取消，这将影响檩条的抗扭刚度和墙梁受力的可靠性。故施工单位不得任意取消设计图纸的一些做法。

In order to save steel and labor, some units cancel the lateral stiffeners supported by steel plates for purlins and wall beams, which will affect the torsional stiffness of purlins and the reliability of wall beams. Therefore, the construction unit shall not arbitrarily cancel some practices of design drawings.

有的单位擅自增加屋面荷载，原设计未考虑吊顶或设备管道等悬挂荷载，而施工中却任意增加吊顶等悬挂荷载，从而导致钢梁挠度过大或坍塌。任何单位均不得擅自增加设计范围以外的荷载。

Some units increase the roof load without authorization. The original design did not consider suspended loads such as suspended ceilings or equipment pipes, but they arbitrarily increase suspended loads such as suspended ceilings during construction, resulting in excessive deflection or collapse of steel beams. No unit shall increase the load beyond the design scope without authorization.

屋面板未按要求设置，将固定式改为浮动式，使檩条侧向失稳。往往设计檩条时，会考虑屋面压型钢板与冷弯型钢檩条牢固连接，能可靠的阻止檩条侧向失稳并起到整体蒙皮作用。

The roof panel is not set as required, and the fixed type is changed to the floating type, which causes lateral instability of the purlin. When designing purlins, the roof profiled steel plate and cold-formed steel purlins will be firmly connected, which can reliably prevent the lateral instability of purlins and play the role of integral skin.

刚性系杆、风拉杆的连接板设置位置高低不一，使得水平支撑体系不在同一平面上，从而影响刚架的整体稳定性。刚性系杆与风拉杆构成水平支撑体系，其设置高度在同一坡度方向应保持一致。

The connecting plates of rigid tie rods and wind pull rods are set at different positions, which makes the horizontal support system not on the same plane, thus affecting the overall stability of the rigid frame. The rigid tie rod and wind pull rod form a horizontal support system, and their setting heights shall be consistent in the same slope direction.
