Description

Technical Field

[0001] The present application relates to the technical field of defects in the mortar bedding layer of shear walls, and particularly relates to a detection device for defects in the mortar bedding layer of precast shear walls. Background Art

[0002] The mortar bedding is placed on the ring beam cornice for the precast slab. The two components are in direct contact, and the contact surface is not necessarily flat, so there will inevitably be some gaps. During the installation of precast shear walls, to solve this problem, before placing the precast shear wall, a layer of mortar is first laid flat on the ring beam, and then the precast shear wall is placed in the mortar. After the mortar solidifies and hardens, the two components can be bonded together; however, to ensure the stability of the precast shear wall, it is necessary to detect the defects in the mortar bedding layer.

[0003] In the patent document with the published publication number CN207976435U, a detection device for defects in the mortar bedding layer of precast shear walls is provided. This published patent document solves the problem that the defects in the mortar bedding layer of precast shear walls cannot be detected, effectively improves the quality of precast structures, and promotes the wide application of precast structures; however, for the above-mentioned published patent, it is necessary to manually tap the position to be detected with a hammer, and the detection is not convenient to use. Utility Model Content

[0004] Aiming at the deficiencies of the prior art, the present application provides a detection device for defects in the mortar bedding layer of precast shear walls, which overcomes the deficiencies of the prior art and aims to solve the problems in the prior art.

[0005] To achieve the above object, the present application provides the following technical solution: A detection device for defects in the mortar bedding layer of precast shear walls, including a shear wall, a precast connection part, and a detection component. There is a mortar bedding layer between the shear wall and the precast connection part. The detection component includes a frame body, a mounting plate, and an ultrasonic flaw detector. The frame body is arranged in front of the mortar bedding layer. Symmetrically arranged moving grooves are opened on the inner walls of the top and bottom of the frame body. The mounting plate is inside the frame body. Symmetrically fixed connection moving blocks are arranged on the top and bottom of the mounting plate. The moving blocks are inside the moving grooves, and the moving blocks are slidably connected with the moving grooves. Detection holes and round holes are opened on the mounting plate. The ultrasonic flaw detector is arranged on the front side of the mounting plate, and a detection probe is connected to the ultrasonic flaw detector through a wire. The detection probe passes through the detection hole, and a marking pen passes through the round hole. The marking pen is slidably connected with the round hole.

[0006] By adopting the above technical solution, the ultrasonic flaw detector arranged on the front side of the mounting plate and the detection probe passing through the detection hole can quickly detect defects in the grouting layer. Moreover, due to the sliding connection between the moving block and the moving groove, the mounting plate can slide horizontally and laterally, so as to move the ultrasonic flaw detector and the detection probe along the grouting layer, thereby quickly adjusting the detection position. And through the marker pen slidably connected to the round hole, the marker pen can be quickly slid to mark the detected defective part, which is relatively convenient to use.

[0007] As a preferred technical solution of the present application, four mounting grooves are opened on the front side of the mounting plate, and bolts penetrate through both sides of the mounting plate. Four corners at the rear side of the ultrasonic flaw detector are fixedly connected with mounting blocks, threaded holes are opened on the mounting blocks, the mounting blocks are located inside the mounting grooves, and the mounting blocks are adapted to the mounting grooves. The bolts are threadedly connected to the mounting plate, and one end of the bolts is located inside the threaded holes.

[0008] By adopting the above technical solution, rotate the bolt to screw its one end out of the threaded hole, then the restriction on the mounting block can be released. Then move the ultrasonic flaw detector forward to move the mounting block out of the mounting groove, and the ultrasonic flaw detector can be removed, which is convenient for the installation and disassembly of the ultrasonic flaw detector.

[0009] As a preferred technical solution of the present application, chutes are opened on the front side of the mounting plate above and below the detection hole. Slide bars are slidably connected inside the chutes. The front sides of the slide bars are located outside the chutes, and springs are fixedly connected to the slide bars. One end of each spring is fixedly connected to the inner wall of the chute. Clamping members are symmetrically arranged on the upper and lower sides inside the detection hole. Connecting rods are fixedly installed on the sides of the two clamping members away from each other. One end of each connecting rod penetrates through the detection hole and is fixedly connected to the corresponding slide bar.

[0010] By adopting the above technical solution, applying opposite forces to the two slide bars, the slide bars squeeze the springs and move. The slide bars drive the two clamping members to move in opposite directions through the connecting rods, thereby releasing the fixation of the detection probe. This is not only convenient for the installation and disassembly of the detection probe, but also can increase the stability of the detection probe during the detection process.

[0011] As a preferred technical solution of the present application, the detection hole and the marker pen are at the same height.

[0012] By adopting the above technical solution, it is convenient to mark the detection location.

[0013] As a preferred technical solution of the present application, support shafts are arranged at the four corners at the rear side of the frame body, and suction cups are fixedly installed at the rear ends of the support shafts.

[0014] By adopting the above technical solution, it is convenient to fix the frame body on the front side of the grouting layer.

[0015] As a preferred technical solution of the present application, threaded grooves are provided at the four corners on the rear side of the frame body, and a threaded shaft is fixedly connected to the front end of the support shaft.

[0016] By adopting the above technical solution, the installation and disassembly of the support shaft are facilitated, thereby reducing the space occupied by the device when it is idle.

And through the marker pen slidably connected to the round hole, the marker pen can be quickly slid to mark the detected defective part, which is relatively convenient to use.

[0019] 2. Through the bolts, mounting grooves, mounting blocks and threaded holes, the installation and disassembly of the ultrasonic flaw detector are facilitated. And through the chute, detection hole, sliding rod, spring, connecting rod and clamping member, not only the installation and disassembly of the detection probe are facilitated, but also the detection probe can be limited during the detection process, increasing the stability during the detection process.
