组立02.jpg

 

  H型钢组装采用中间焊点、自动对中组立机;组装前,零件、部件全部检查合格;连接接触面和焊缝边缘30-50mm范围内的铁锈、毛刺、污垢、冰雪等清理干净。组装精度完全满足国家标准《钢结构工程施工及验收标准-GB50205-2001规定。


  Asscmblling of H shape stccl with the middle joint and auto alignment machine. Checking all components and ensuring they are qualif-ied before assemblling. Cleaning the rust, burrs, diriy, ice or snow on the contact surface and the surface within 30-50mm of the weld edges. Assembling precision fully meets the national standard of GB5025-2001:Code for acceptance of construction quality of steel structurcs.

  碳素结构钢在环境温度低于-16℃时,低合金结构钢在环境温度低于-12℃不得进行冷矫正和冷弯曲;碳素结构钢和低合金结构钢在加热矫正时,加热温度不得超过900℃;矫正后的钢材表面无明显的凹痕或损伤,划痕深度小于0.5mm;钢结构矫正后的偏差符合现行国家标准《钢结构工程施工及验收规范》GB50205-2001。


  Carbon structure steel and -12℃ for low-alloy structure steel. The temperature of heated correction couldn't higher than 900℃  for both steels. There will not be obvious dents and damage and the scratches deeper than 0.5mm on the corrected surface. The deviation after corrected is according to the national standard GB50205-2001 .

  钢构件在涂层之前应进行除锈处理,锈除得干净则可提高底漆的附着力,直接关系到涂层质量的好坏。本公司采用大型抛丸清理机满足这一涂装工艺的要求,使构件达到Sa3除锈等级。该机设有多个抛丸器大型清理室,可满足各种钢构件及H型钢的表面清理要求。


  Before coating, rust treatment should be done, for steel components rust primer in addition to clean and can improve the adhesion of the coating is directly related to the quality of the good or bad. The company uses a large

abrator coating process to meet this requirement, so that components reach Sa3 rust grade. The machine has a number of large-scale clean-up shot blasting rooms, which can meet various requirements of steel components and surface

cleaning H-beam.
