Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a clamping device for a concrete placing machine. Background Technology

[0002] Currently, in large-scale construction projects, concrete pump trucks combined with pump pipes and placing booms are commonly used for zonal pouring. During the pouring process, concrete pumping is paused when the concrete trucks are handed over; when the pouring point is moved, the tower crane moves the placing boom, pausing concrete pumping again. When concrete pumping is paused, residual concrete in the placing boom can easily flow out and fall onto the reinforcing steel in the unpoured areas. If the pause is prolonged, the concrete can easily clump and contaminate the reinforcing steel. Once contaminated, the steel is difficult to clean, and if not cleaned properly, it will directly affect the bond strength between the subsequent concrete and the reinforcing steel, impacting the quality of the concrete pouring and structural safety. Utility Model Content
