The Use Of Pre-embedded Anchor Bolts

The quality of the embedded parts of the anchor bolts will affect the installation quality of the steel structure building, so we must master and control the position, verticality, length and elevation of the anchor bolts, so as to reduce the workload of reaming and adjustment, In addition, it can prevent rework, so it is of great significance to improve the quality of steel structure installation. The pre-embedding method of the anchor bolts here can adopt the direct pre-embedding method or the reserved hole method. What should be emphasized here is that the supervision engineer must strictly check the rationality and reliability of the construction method of the embedded bolts before the foundation concrete is poured, and whether the measured indicators are within the scope of the standard rules. If the equipment is installed on a concrete beam, the anchor bolts are generally pre-buried. If the equipment foundation has other special requirements, the casing can also be pre-embedded on the concrete beam by the civil engineering professional to facilitate the penetration of the anchor bolts. The size of the casing here should make the clearance between the anchor bolt and the casing at least 10mm, so that the bolt position can be adjusted and sand filled and compacted when the equipment is installed.
