IMPROVEMENT OF MEASURING EQUIPMENT FOR EXPERIMENTAL CONTROL OF BUILDING STRUCTURES PARAMETERS ON A CONSTRUCTION SITE

Abstract

Abstract. The article analyzes the current state of measuring devices for recording deflections on the Ukrainian market. It concludes that there are no analogs to traditional deflectometers. The main features of using this equipment on construction sites or factory production sites are presented. The importance of installing measurement equipment with protection systems against structural collapse and avoiding external influences on the measuring equipment has been noted. The prototypes used by other organizations were reviewed. The prototype developed based on laser sensors showed satisfactory accuracy results. The low reliability of this approach was noted due to the imperfection of the optical system. A new design using digital devices for metalworking machines has been proposed. The measuring instrument consists of a digital micrometer, a plastic case, a counterweight basket, and steel weight plates. A comparison was made with two deflectometers that passed metrological control and verification. Minor deviations and discrepancies were reported. A repeat test was conducted using clock-type indicators. The results confirmed the high accuracy of measurements. Based on the conducted research, a conclusion was made about the admissibility of using the proposed device for deflection measurements. The main directions for improving the electronic system of the device and expanding its functionality were indicated. Prospects for registration “KYIVOBLSTANDARTMETROLOGY” indicate measurement accuracy at the level of 0.01 mm.
