Abstract

The invention discloses a device and a method for testing the anti-pressure ability of reinforcing steel bars for buildings, and relates to the technical field of anti-pressure ability testing of reinforcing steel bars. The problem that the flexibility of the steel bar at different temperatures is not measured is solved. The device comprises a shell, two first sliding grooves are formed in the inner wall of the bottom of the shell, two supporting frames are slidably connected to the interiors of the two first sliding grooves through two adjusting mechanisms correspondingly, and limiting mechanisms are arranged on the outer walls of the tops of the two supporting frames correspondingly; the testing method of the device comprises the following steps: limiting the reinforcing steel bar; adjusting a supporting point; adjusting the temperature of the reinforcing steel bar; and carrying out pressing measurement. By arranging the sliding frame and the telescopic mechanism, the semiconductor cooler can be in contact with the reinforcing steel bar, the semiconductor cooler is connected with two different metal conductors through the conductor, then direct current is connected, the temperature is changed, and therefore the reinforcing steel bar is cooled or heated, and the compression resistance of the reinforcing steel bar at different temperatures is measured.

Description

technical field [0001] The invention relates to the technical field of steel bar compression testing, in particular to a testing device and a testing method for the steel bar compressive capacity used in construction. Background technique [0002] In the prior art, building materials are a general term for materials used in civil engineering and construction engineering, and can be divided into structural materials, decorative materials and some special materials. The requirements for structural materials are extremely strict, because structural materials are directly related to the quality of building structures. Stability, among which reinforced concrete is the main building structure type in our country. The strength of the steel bar directly affects the structural strength of the concrete. For example, the compressive performance of the steel bar is directly related to the bearing capacity of the concrete. Therefore, the compressive test of the steel bar is very important...
