Railing post

Construction line → pre-embedded bolts in foundation concrete → (steel structure processing) portal frame hoisting → crane beam installation → steel beam installation → roof truss, roof panel and eaves installation → wall panel installation → steel structure painting.
 

(1) In accordance with the design requirements and the drawings, the elevation and axis will be verified and approved in cooperation with the civil engineering unit.

(2) Before construction, use theodolite to recheck the axis, and use the level to determine the elevation, and use the ink line to make a mark on the fixed object that is not easily damaged, indicate the elevation, and make a record.

(3) After determining the axis and elevation, that is, after placing the large sample, then placing the small sample, that is, determine the edge line of the connecting surface and the vertical and horizontal cross axis of each steel column on the foundation concrete, that is, the position of the column foot of the portal frame .

(4) When positioning the rigid frame, try to avoid the collision between the column foot of the rigid frame and the bolt to avoid the deformation of the bottom surface of the rigid frame column, and reduce the contact surface with the foundation concrete from the surface, and the bending deformation of the bolts will cause the bolts to be straightened. The strength loss to the bolt afterwards.
