Guangzhou steel structure before the installation of steel roof truss, the installation unit does not civil units in the stent bearing embedded in the anchor bolts for inspection and acceptance. This is not re-measured, I do not know the embedded limb bolts and design drawings and steel roof truss at both ends of the installation hole size is consistent with the installation to be found only when the location, size, elevation or error, Installation is not on, need to hang down, the end of the bolt or roof trimming hole to be trimmed before they can be installed, both delay the construction period, but also increase the construction costs. So how do these problems be avoided?

Guangzhou steel structure steel truss before installation, civil engineering, manufacturing, installation of the three sides of the civil pillars to the following inspection and acceptance: Check the anchor bolts size, elevation, pitch, thread exposure length, etc. within the tolerable range, the span is with the steel structure size Consistent with the requirements of the drawings are consistent. After the acceptance of the acceptance, before the steel roof truss to install, to ensure that the installation location, elevation, span and so correct.
