Scaffold fastener tightening torque monitoring device

Abstract

The invention relates to the technical field of building construction, and discloses a scaffold fastener tightening torque monitoring device which comprises a T-shaped bolt, a strain gauge and a digital display detector. The strain gauge is fixed to the surface of an unthreaded rod section of the T-shaped bolt through a sputter coating technology, and the digital display detector is fixed to a scaffold through a metal hoop. A connecting wire is arranged at the tail end of the strain gauge, the digital display detector is connected with the strain gauge through the connecting wire, and a bridge, an A / D conversion module and a single chip microcomputer are arranged in the digital display detector. The connecting wire is connected with the bridge and the strain gauge, the bridge is electrically connected with the A / D conversion module, and the A / D conversion module is electrically connected with the single chip microcomputer. Compared with the prior art, the scaffold fastener tightening torque monitoring device can monitor and collect the torque change condition of a scaffold fastener in real time, and multiple guarantees are provided for the scaffold construction safety; the tightening torque information is collected through the T-shaped bolt, the original structure of the scaffold is not changed, the installation is easy and convenient, and the usage effect is excellent.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a monitoring device for tightening torque of scaffold fasteners. Background technique [0002] Fastener-type steel pipe scaffolding uses steel fasteners as connecting parts. The tightening degree of the fastener bolts has a significant impact on the bearing capacity of the steel pipe scaffolding. If the tightening torque is insufficient, the fasteners are prone to slipping during the concrete pouring process. Therefore, in In the process of scaffolding construction, attention must be paid to the fastening quality of fastener bolts. [0003] In the prior art, the tightening torque inspection of fasteners is generally carried out after the installation is completed, and the torque wrench is mainly used for manual inspection, which has a large workload and low efficiency; the installation workers often operate only by hand feel and experience in the process of tighteni...

Problems solved by technology

[0003] In the prior art, the tightening torque inspection of fasteners is generally carried out after the installation is completed, and the torque wrench is mainly used for manual inspection, which has a large workload and low efficiency; the installation workers often operate only by hand feel and experience in the process of tightening bolts. It is impossible to determine whether the tightening torque has reached the standard during the installation process, which will further increase safety hazards; in addition, during the concrete pouring process, the deformation of the frame caused by sudden load changes or vibration may also lead to loosening of the fastener bolts, which is difficult to detect in time
