Description

Technical Field

[0001] The utility model mainly relates to the technical field of wall strength detection, in particular to a device for measuring a rebound detection angle in a rebound test. Background Art

[0002] In construction projects, strength testing of walls is one of the most important steps. Strength testing can help ensure the structural stability and safety of the building. The main purpose of strength testing is to determine the compressive strength of building materials (such as concrete) to ensure that they meet the design and construction requirements. In the process of wall strength testing, testers often use digital rebound testers. Digital rebound testers are an instrument used to measure the hardness of materials. It determines the hardness of materials by measuring the size of the elastic deformation of the material surface. The principle is based on the elastic deformation and rebound characteristics of the material. The hardness value of the material is calculated by measuring the rebound height of the material surface.

[0003] The existing technology usually uses an ordinary protractor to measure the rebound detection angle of the rebound test, which is inefficient and cannot read the readings in real time as the rebound hammer test angle changes; using an ordinary protractor to measure the rebound detection angle of the rebound test cannot adapt to the real-time measurement of the rebound test angle of concrete components with changing angles, which can easily cause errors in the rebound test angle.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0022] Please refer to the attached Figures 1 to 3 A device for measuring the rebound detection angle in a rebound test includes a box body 1, which is provided with an angle detection mechanism and a horizontal detection part. The angle detection mechanism cooperates with the horizontal detection part. An adjustable fixing component is provided on the outer side of the box body 1, and the fixing component is used to fix the box body 1 on the rebound tester 4.

[0024] The implementation principle of the device for measuring the rebound detection angle in the rebound test of the utility model is as follows:

[0025] Place the box 1 on top of the rebound hammer 4. Adjust the level of the box 1 to ensure that when the rebound hammer 4 is placed horizontally, the liquid level in the box 1 coincides with the 0° horizontal line of the angle ruler 2 inside the box 1. After adjusting the two clamping rings 3 to the appropriate size, use the fixing screws 31 to secure the box 1 to the rebound hammer 4.

[0026] The rebound hammer 4 equipped with the device is held perpendicular to the surface of the concrete component according to the existing technology or existing regulations.

[0027] At this time, the liquid in the box 1 flows along the rebound hammer 4, and the liquid surface has an inclined angle.

[0028] The angle of the liquid surface displayed on the angle ruler 2 is read through the angle ruler 2 in the box 1. This angle is the rebound detection angle of the rebound test and is recorded.
