Intelligent force testing device of steel pipe scaffold based on wireless transmission

Abstract

The present invention discloses a wireless transmission device for a steel pipe scaffold bearing test. The wireless transmission device comprises a wireless signal receiving and processing module, a power supply, a sensing element, an analog-to-digital conversion module, an intelligent logic module and a wireless signal transmission module; wherein the sensing element, the analog-to-digital conversion module, the intelligent logic module and the wireless signal transmission module are electrically connected in proper order; the sensing element is arranged on the external surface of the end portion of a steel pipe; the lead-out / lead-in wires of the sensing element are connected with other elements in the steel pipe through the steel pipe port; through holes are arranged on the shell of the steel pipe; and the wireless signal transmission module includes a transmitting antenna which is exposed from the steel pipe by means of the through holes. The wireless sensing device provided by the present invention adopts a mode that wireless elements and circuit elements are built-in so as to prevent the circuit from exposing and to overcome the shortage that a transmission cable is prone to breakage when the current pressure transducer carries out a bearing test for the steel pipe scaffold.

Description

technical field [0001] The invention relates to a wireless sensing device for stress testing steel pipe scaffolding, in particular to a wireless sensing device for pressure of steel pipe scaffolding in various construction processes and temporary support processes. Background technique [0002] The formwork support system composed of steel pipe scaffolding is used as the carrier of the concrete structure construction, which will bear the self-weight load of the newly poured concrete structure and the construction live load. Due to the insufficiency of the existing steel pipe scaffolding calculation theory, the defects in the scaffolding process and the absence of construction management, the scaffolding support system is prone to collapse accidents, and monitoring the force of the scaffolding is one of the main means to prevent such accidents. . The force test of the steel pipe scaffold usually uses a pressure ring sensor, and the data is collected by manually using a mobil...

AI Technical Summary

Problems solved by technology

The force test of the steel pipe scaffold usually uses a pressure ring sensor, and the data is collected by manually using a mobile measuring device on a regular basis. This is not conducive to timely changes in the force of the steel pipe scaffold. Therefore, the force monitoring of steel pipe scaffolding has gradually changed to a long-term test method. However, the current long-term test method mainly uses wired data transmission to achieve data collection. There is a problem that the transmission cable is extremely vulnerable to falling objects on the upper floor during construction. Insufficient personnel damage caused the frequent interruption of signal collection, and it was still impossible to collect countermeasures in time for the stress changes of steel pipe scaffolding
