Pre embedded steel bar inspection, repair, embedded reinforcement inspection,

A good cleaning groove and the beam of debris, first check the embedded tendons in good condition, such as deformation to straightening, making it one of the Qing good groove and the beam of debris, first check the embedded tendons in good condition, such as deformation should be straightened, and the exact form; if there is flaw and crushed, it must be planted, planting in accordance with the direction of the anchor bolt joints, and the form is accurate; if there are missing and damaged, it must be planted, planting in accordance with the direction of the anchor bolt joints, bolts and joints to ensure the anchor bolt has good welding stress and ensure anchorage. With the expansion joint of anchoring steel has good mechanical andThe welding reinforced design. Homologous pre buried steel of the same size of anchorage, anchorage construction, selection of reliable quality. Ensure the anchorage bar planting technique, were planted, were planted during the construction, the selection of reliable quality. To ensure the anchorage bar planting technique, adhesive should meet the requirements of welding, after welding bearing capacity decreased, and with the corresponding testing report. Meet the design requirements before the installation of telescopic device. After welding bearing capacity decreased, and has the corresponding testing report. To meet the design requirements before installation of expansion device. Finally, the corrosion of steel parts using iron rust brush clean. Finally, the corrosion of steel partWith the iron rust brush clean. Part of the use of iron rust and clean brush

Check whether the gap between the beam is in line with the requirements, if not in line with the need for processing has reached the requirements. Check the gap between the beam is in line with the requirements, if not in line with the need to handle has reached the requirements.

The check whether the corresponding embedded bar with a telescopic device anchoring ring, such as the existence of dislocation, phase torsion problems should be adjust the anchor ring. Check whether the corresponding pre buried steel and anchor ring expansion device, such as the existence of dislocation, phase torsion problems should be adjust the anchor ring.

How to ensure the effective connection of embedded steel ring and the welding seam, should be based on the actual size, preparation of a number of different specifications to ensure that the effective welded steel ring and embedded parts, should be based on the actual gap size, steel plate as liners. Steel as liners.

Check the concrete beam and the top beam at the end of the existence of defects, the defect should be reinforced. The top of the beam and end beam inspection of concrete defects, the defect should be reinforced.
