Adjustable building anchor rod anti-pulling detection device

Abstract

The invention relates to the field of constructional engineering, in particular to an adjustable building anchor rod anti-pulling detection device which comprises a supporting plate and a fixing plate, an anchor rod anti-pulling detection instrument is installed on the supporting plate, a through opening is formed in the middle of the fixing plate, and the supporting plate and the fixing plate are connected through an angle adjusting device. The angle adjusting device comprises an adjusting structure and a fixing structure, the fixing plate is attached to the mounting face, then the angle between the supporting plate and the fixing plate is adjusted through the adjusting structure, and therefore the supporting plate is perpendicular to the axis direction of the anchor rod; and then the adjusting structure is fixed through the fixing structure, and the fixing plate can be fixed to the mounting faces with different gradients so as to adapt to the situation that the mounting faces and the axis direction of the anchor rod form different angles.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to an adjustable construction bolt pullout detection device. Background technique [0002] Anchor rods are the basic components used for support in engineering, and can be used for main body reinforcement of building walls, slopes, tunnels, dams, etc. As a tension member that goes deep into the ground, the anchor rod is connected to the engineering structure at one end, and the other end goes deep into the ground. According to GB50086-2001 "Technical Specifications for Bolt Shotcrete Support", the bolt support must be tested for strength, which includes the part of the bolt pullout test. According to the relevant requirements of the bolt pullout force test, the tension and When locking, the pressure-bearing surface of the testing instrument pedestal should be flat and perpendicular to the axis direction of the anchor rod. The direction of the anchor may not be vertical, and...

According to GB50086-2001 "Technical Specifications for Bolt Shotcrete Support", the bolt support must be tested for strength, which includes the part of the bolt pullout test. According to the relevant requirements of the bolt pullout force test, the tension and When locking, the pressure-bearing surface of the testing instrument pedestal should be flat and perpendicular to the axis direction of the anchor rod. The direction of the anchor may not be vertical, and special types such as anti-floating anchors often have a certain degree of bending at the protruding end of the anchor. This type of anchor often needs to be straightened first when measuring with a common anchor pullout instrument , very inconvenient
