Abstract

The invention relates to a construction method for adjusting steel plate embedded parts to reach design and construction accuracy. The construction method comprises following steps: welding four screw rods in the vicinity of four right-angle positions under a pre-embedded steel plate having a pre-embedded steel plate anchor bar when each pre-embedded steel plate is installed; first screwing leveling nuts to each rotary screw rod and penetrating into sleeves; welding sleeves with sleeve fixation rebars; anchoring sleeve fixation rebars to a fundamental plane prior to installation of the pre-embedded steel plate; measuring and adjusting each leveling nut such that the elevation of top surface and horizontal plane accuracy of the pre-embedded steel plate satisfy the design requirement; and ultimately, screwing clamp nuts and fixing the pre-embedded steel plate in order to prevent the pre-embedded steel plate from being lifted by uplift pressure of concrete during the process of pouring foundation concrete. The construction method for adjusting the steel plate embedded parts to reach design and construction accuracy has following beneficial effects: when hole opening operation is not conveniently performed for the pre-embedded steel plate and no installation and leveling device is available, the method and a device are easy and practical; operation is performed easily; and easy operation, high installation accuracy and efficiency are obtained.
