The basic contents and requirements for the installation of light steel structures are the same as those for ordinary steel structures. In the construction of steel column foundations, the positioning and protection of the anchor bolts should be well done, and the foundation and elevation of the anchor bolts should be controlled. After the foundation construction, the following inspections shall be carried out:
(1) Whether the position of the axes of each row is correct;
(2) Whether each span meets the design requirements;
(3) Whether the base top elevation meets the design requirements;
(4) Whether the position and elevation of the anchor bolt meet the design and specification requirements.
Before the components are hoisted, according to the relevant provisions in the "Code for the Construction and Acceptance of Steel Structure Engineering", the shape and cross-sectional geometry of the components shall be inspected. The deviation shall not exceed the specified value; the components shall be numbered according to the requirements of the design drawings and pop up. Installation center mark. The steel column should pop up the center mark and elevation mark in both directions; mark the location of the lashing point; measure the length of the column, and record the length error in detail, and use the oil pen to write on the plane next to the center mark on the lower part of the column to prepare for the foundation top. The surface elevation is adjusted in the secondary grouting layer.
Components entering the construction site must have quality assurance documents and detailed acceptance records; they should be stacked in designated areas according to the type, model, and installation sequence of the components. The strata of the component stratum shall have sufficient supporting surfaces to prevent the fulcrum from sinking; when the same type of components are stacked, the fulcrum of each component shall be on the same straight line; the deformed components shall be promptly corrected, and the components may be installed after being inspected.
The work table of the tile press machine has six processes, namely, the flipping of the worktable of the six-way runner. In addition to the mechanical indexing and positioning of the first-grade machine, a set of precision positioning mechanism is also provided to completely ensure the work during each punching process. The accurate positioning of the mold, the mounting slide is a box structure, sliding guide rails and guide rails on the fuselage, the contact length is large, each stamping of the upper mold, the process has a second stamping of the mold that is the first mold After the secondary pressure billet is in place, the upper mold rises by 10 ,, so that after the slush billet is fully exhausted, the upper mold presses the sliver again downwards before returning to the highest position, thus the service life of the mold is longer.
