Abstract

The utility model discloses a joint clamping device and a joint clamping system. The joint clamping device comprises a clamping assembly and a screw rod assembly. The screw rod assembly comprises an adjusting rod, a screw rod and a nut, one end of the screw rod is fixedly connected with the adjusting rod, and the other end of the screw rod penetrates through the fixing rod to be in threaded connection with the nut. The adjustable clamping force is realized through the screw rod assembly, so that the adjustable clamping force is suitable for the practically existing joint gaps, and the adaptability of the device to different installation precision is improved. The width requirement of the movable rod and the fixed rod on the support template is relatively reduced by adjusting the angle between the movable rod and the fixed rod. The device allows larger installation tolerance, and improves the installation convenience and efficiency.

Description

Piece clamping device and piece clamping system Technical Field The utility model relates to the technical field of concrete construction, in particular to a joint clamping device and a joint clamping system. Background In an assembled concrete structure, the processing of the superimposed sheet joint is a key for realizing structural integrity and ensuring casting quality of a cast-in-situ layer. However, the prior art has the obvious problems that most devices which rely on rigid connection (such as a screw rod and a pre-buried sleeve) cannot adapt to the 5mm installation error allowed by the technical regulations of assembled concrete structures, manual gasket adjustment is needed, the efficiency is low, and slurry leakage is easy. The existing sealing mostly adopts static slurry stopping sheets or adhesive tapes (such as CN 110847413A), and cannot provide dynamic pressing force. Vibration during concrete pouring is easy to shift the sealing element, so that slurry seeps out, and secondary plugging is needed. Part of the supporting devices (such as arched angle brackets) have high requirements on the position of the embedded part. The pre-buried deviation (such as 10 mm) often leads to the device incapable of being installed or needing on-site reconstruction, and increases the construction difficulty. The traditional bolt clamping is easy to damage the edge (especially the thin plate) of the laminated slab due to overlarge strength, and slurry leakage is caused due to insufficient strength, so that the construction quality is difficult to ensure. Therefore, the prior art cannot meet the requirements of efficient, reliable and convenient superimposed sheet joint processing, and needs to be improved.
