Constructional engineering steel bar strength detection device

Abstract

The invention discloses a constructional engineering steel bar strength detection device. The constructional engineering steel bar strength detection device comprises a detection frame, and a replacement device is arranged at the bottom of the detection frame. With the replacement device, people can quickly replace a clamping device matched with the reinforcing steel bar according to the diameterof the reinforcing steel bar, and the applicability and the practicability of the reinforcing steel bar strength detection device are improved; with an angle monitoring device, people can observe thebending angle of the steel bar in real time; with a transmission device, the reinforcing steel bars can be kept still in any bending angle state, it is ensured that people can detect the bending strength of the steel bar at different bending angles, and the applicability and the practicability of the reinforcing steel bar strength detection device are further improved; through the cooperation of adriving device, the transmission device and a pressure applying device, people can apply bending force on the reinforcing steel bar by of the own gravity, the operation process is simple, convenient,time-saving and labor-saving, the detection work is easier, the practicability of the reinforcing steel bar strength detection device is further improved, and the practicability is remarkably improved.

Description

technical field [0001] The invention relates to the field of steel bar strength testing equipment, in particular to a construction engineering steel bar strength testing device. Background technique [0002] Steel bar refers to steel for reinforced concrete and prestressed reinforced concrete. Its cross section is circular, sometimes square with rounded corners. It is mainly used in various large, heavy, light thin-walled and high-rise building structures. It is divided into There are three types of steel bar, ribbed steel bar, and twisted steel bar. In recent years, the rapid development of high-rise buildings, large and medium-sized public facilities and municipal engineering, and new urban and rural residential construction in cities has made reinforced concrete structures the most widely used in today's society. A form of building structure, and the steel bar is the skeleton of the reinforced concrete structure, so the strength performance of the steel bar material plays...

Problems solved by technology

[0003] Existing steel bar strength testing devices for construction projects are usually composed of a testing frame and a testing instrument host. When in use, people place the steel bars to be tested inside the testing bracket, and then shake the rocker to move the pressing bar down. The pressing block under the pressing bar Apply pressure to the steel bar and bend the steel bar, the pressure sensor between the pressure bar and the pressing block can transmit the force received by the steel bar during the bending process to the main unit of the testing instrument in the form of electrical signals, and people can use the data on the main unit of the testing instrument to The flexural strength of the steel bar is known, but the bending angle of the steel bar is fixed by the existing construction steel bar strength detection device, people cannot detect the flexural strength of the steel bar at different bending angles, and cannot effectively measure the steel bar Fixed, during the bending test of the steel bar, the steel bar is easy to slide and pop up, causing safety accidents, and the safety performance is low. Therefore, it is urgent to design a device for detecting the strength of steel bars in construction engineering
