AI Technical Summary

Technical Problem

The existing leveling device for prefabricated bridge beams has problems such as the wedge-shaped concrete cushion stones being easily damaged, the leveling accuracy is difficult to guarantee, and the wedge-shaped steel plates are high in processing costs and complex installation.

Method used

A leveling device for inlaid support steel plates of prefabricated beams is designed, including support steel plates, inlaid grooves, bolts and flexible material filling layers. Through the adjustment of bolts, the embedding depth control of the support steel plate is achieved, and the flexible material filling layer is used to prevent concrete slurry from entering the gap.

Benefits of technology

The device can adjust the embedding depth according to the on-site situation, improve leveling accuracy, reduce processing and installation costs, and is suitable for industrial prefabricated construction and meet project quality requirements.

Abstract

The utility model discloses a precast beam embedded support steel plate leveling device which comprises a support steel plate, the support steel plate is located on one side of the bottom of a beam body, a sunken groove is formed in the position, corresponding to the support steel plate, of the bottom of the beam body, the support steel plate is embedded into the sunken groove, a bolt movably penetrates through the periphery of the bottom of the support steel plate, and the support steel plate is embedded into the sunken groove. The bottom end of the bolt is sleeved with a nut in a screwed mode, the length of the portion, extending into the support steel plate, of the top end of the bolt is adjusted through the nut, the beam body is placed on the beam bottom die, and the space between the beam bottom die and the support steel plate is filled with a flexible material filling layer. The leveling device can adjust the embedding depth of each angular point on site according to actual conditions, meanwhile, the bolts for adjustment are standard parts, the machining precision is reliable, the use cost is low, construction is convenient and fast, and the leveling device is more suitable for leveling construction of the prefabricated beam embedded support steel plate. The device can save labor, accelerate the construction progress and meet the engineering quality requirement.
