钢格板长度和宽度所允许的偏差都为±5mm
钢格板需要由负载扁钢和横杆按一定的经纬排列且留有一定的间距而成格栅,经向为长度方向是负载扁钢,纬向是宽度方向为横杆。在横杆和负载扁钢每个交插点处都需要将其固定住,可以焊接处理,但是最好是压力电阻焊,但也可采用电弧焊焊接。如采用压锁方法固定时可用压力机将横杆直接的压入负载扁钢内从而达到固定的效果。
The steel grating needs to be made of the load flat steel and the cross bar arranged according to certain longitude and latitude with certain spacing. The longitude direction is the load flat steel, and the latitude direction is the width direction is the cross bar. It is necessary to fix the cross bar and load flat steel at each intersection, which can be welded, but it is better to use pressure resistance welding, but it can also use arc welding. If the press lock method is used for fixing, the cross bar can be directly pressed into the load flat steel by a press to achieve the fixed effect.
钢格板上的负载扁钢可以采用平面扁钢、 I型扁钢或纵剪带钢这几类。如果是用于平台就是走道上的钢格板,其最小宽度不能够小于300mm。在负载扁钢之间的间距推荐采用30mm,35mm或者40mm,而横杆之间的间距推荐采用100mm,76mm或50mm。
The load flat steel on the steel grid can be plane flat steel, I-type flat steel or longitudinal shear strip steel. If it is used for the steel grating on the platform or walkway, its minimum width shall not be less than 300 mm. It is recommended to use 30mm, 35mm or 40mm spacing between load flat steel and 100mm, 76mm or 50mm spacing between cross bars.
钢格板长度和宽度所允许的偏差都为±5mm,负载扁钢的不垂直度需要小于扁钢宽度的10%。横杆边缘对钢格板中心的偏斜长度应小于5mm,其纵向弯曲挠度要小于其长度的1/200,而横向弯曲挠度则要超过其宽度的1/100。
The allowable deviation of the length and width of the steel grating is ± 5mm, and the non perpendicularity of the load flat steel needs to be less than 10% of the width of the flat steel. The deflection length of the edge of the cross bar to the center of the steel grating shall be less than 5mm, the longitudinal bending deflection shall be less than 1 / 200 of its length, and the transverse bending deflection shall be more than 1 / 100 of its width.
