Description

Technical Field

[0001] The utility model belongs to the technical field of engineering detection equipment, and in particular relates to an auxiliary bracket for a rebound tester. Background Art

[0002] The mortar rebound test hammer is a device for testing the compressive strength of mortar. Its working principle is that the spring in the rebound test hammer drives the impact hammer, and the impact rod hits the sample surface to generate a restoring force of instantaneous elastic deformation. This restoring force drives the impact hammer to drive the pointer to rebound and indicate the rebound distance (i.e., the rebound value). The rebound value can be used as one of the relevant indicators for evaluating the compressive strength of mortar. The mortar rebound test hammer is suitable for non-destructive testing of the compressive strength of masonry mortar in sintered ordinary brick masonry of general industrial and civil buildings. It is the most widely used non-destructive testing instrument for concrete compressive strength for on-site testing. It is also the fastest, simplest and most economical test method for obtaining concrete quality and strength.

[0003] However, according to the national standard, when measuring concrete structural parts, it is usually necessary to evenly test the data of 16 points in a test area. During the test, the rebound hammer needs to be manually held to apply force. During each operation, the operator needs to keep the rebound hammer vertical to the structural part, which is inconvenient in use. Utility Model Content

[0004] In order to solve the above-mentioned deficiencies in the prior art, the utility model provides an auxiliary bracket for a rebound tester.

[0005] The present application proposes an auxiliary bracket for a rebound tester, comprising two front and rear frames, which are connected by a number of spring telescopic rods. A long strip block that can move up and down is movably installed in the front frame, a through groove is provided at the front end of the long strip block, and guide grooves are provided at the upper and lower inner walls of the through groove respectively. A guide block that always moves in the guide groove is slidably installed in the guide groove, connecting plates are fixedly installed at the opposite ends of the two guide blocks, and arc-shaped clamping plates that can move relatively are respectively arranged at the opposite ends of the two connecting plates, and suction cups are fixedly installed at the four corners of the rear end of the frame located at the rear.

[0006] Specifically, the inner walls on both sides of the frame located in the front are respectively provided with sliding grooves, and sliding blocks are respectively fixedly installed on both sides of the two long blocks, and the sliding blocks are inserted into the sliding grooves.

[0007] Specifically, a screw rod is installed on a bearing on one side of the front end of the connecting plate, and the opposite ends of the two screw rods are fixedly connected by a connecting block, the threads of the two screw rods are opposite, a fixed plate is fixedly installed on the other side of the front end of the connecting plate, and the two fixed plates are fixedly connected by a guide rod, a nut is fixedly installed on one side of the front end of the arc-shaped clamping plate, and the screw rod passes through the nut, and a guide sleeve is fixedly installed on the other side of the front end of the arc-shaped clamping plate, and the guide rod passes through the two guide sleeves.

[0009] Place the frame on the test area, suck the outer surface of the test area with the suction cup, place the rebound hammer between the two arc-shaped clamps, and then clamp the rebound hammer with the two arc-shaped clamps. When testing in the test area, the rebound hammer can move back and forth left and right through the movement of the guide block in the guide groove, and then the long block can move up and down, thereby driving the rebound hammer to move up and down. Multi-point detection can be performed in the test area, and through the spring telescopic rod, when the rebound hammer is pressed backward, the frame in front can be driven to move backward, which is more convenient during the detection process, and the rebound hammer can also be kept vertical to the test area during the detection process, so that the detection is more accurate.

The frame 1 is placed on the test area, the suction cup sucks the outer surface of the test area, the rebound hammer is placed between the two arc-shaped clamping plates 6, and then the two arc-shaped clamping plates 6 clamp the rebound hammer. When the test is carried out in the test area, the rebound hammer can be reciprocated left and right by moving the guide block in the guide groove, and then the long block 2 can move up and down, thereby driving the rebound hammer to move up and down, and multiple points of detection can be carried out in the test area. When the rebound hammer is pressed backward through the spring telescopic rod, the frame in front can be driven to move backward, which is more convenient during the detection process, and the rebound hammer can also be kept vertical to the test area during the detection process, so that the detection is more accurate.
