回弹仪是一种机械式非破损检测仪,其工作原理是:砼或其他建筑材料的极限抗压强度与表面硬度,冲击锤的回跳高度之间,在一定的条件下存在着函数关系,利用这一规律可制作成各种规格的回弹仪,它具有结构简单、轻巧、便于携带、操作方便、测试迅速等特点,适用于野外和现场作为非破损测强与工程质量检查手段,根据用途和冲击动能大小的不同,回弹仪分为以下几种: 1.HT225型回弹仪,也叫中型回弹仪,可供一般建筑物,桥梁和工地,预制厂等对各
The rebound tester is a mechanical non-destructive tester. Its working principle is: there is a functional relationship between the ultimate compressive strength and surface hardness of a concrete or other building materials, and the rebound height of an impact hammer under certain conditions. The use of this law can be made into a variety of specifications of the rebound instrument, it has a simple structure, lightweight, easy to carry, easy to operate, rapid test and other characteristics, suitable for field and field as a non-destructive strength measurement and engineering quality inspection methods, According to the purpose and impact of different kinetic energy, the rebound instrument is divided into the following types: 1.HT225 type rebound instrument, also called medium-type rebound instrument, can be used for general buildings, bridges and construction sites, precast plants, etc.
