Description

Sleeve grouting plumpness monitor Technical Field The utility model relates to the technical field of sleeve grouting, in particular to a sleeve grouting fullness monitor. Background The connection between each fashioned post beam slab wall part of assembled building is through reinforcing bar sleeve connection, and two reinforcing bars are connected respectively at telescopic both ends, in order to make sleeve, part, the combination of reinforcing bar fastening as an organic whole, pours into a kind of concrete grouting material into the sleeve into, and after the grouting material solidifies, sleeve and both ends reinforcing bar fastening combine. Aiming at the phenomenon of non-filling of the sleeve grouting, a common detection mode is to monitor and detect the filling fullness of the sleeve grouting by a damping vibration method. However, the existing sleeve grouting satiation detector is high in price, the miniature sensor of the detector cannot be taken out after grouting solidification, the cost is too high, the detector is not suitable for wide application, only individual sleeve grouting can be sampled and detected, and the requirement of production safety detection cannot be met obviously due to the fact that the number of grouting sleeves used in an assembled building is extremely large. The utility model patent with publication number of CN215339849U discloses a sleeve grouting fullness monitor, which belongs to the field of sleeve grouting and solves the problems that the internal fullness cannot be observed, the fullness monitor is high in price and the operation is complex in the prior art when sleeve grouting is carried out.
