Description
技术领域technical field
本发明涉及测量工具技术领域，尤其是涉及一种混凝土扩展度测定仪。The invention relates to the technical field of measuring tools, in particular to a concrete expansion degree measuring instrument.
背景技术Background technique
混凝土拌合物性能检测是混凝土技术质量控制中的必要手段。混凝土扩展度测量是大坍落度混凝土所必须检验的项目，特别是自密实混凝土。Concrete mixture performance testing is a necessary means in the quality control of concrete technology. Concrete expansion measurement is a must-test item for large slump concrete, especially self-compacting concrete.
依据《普通混凝土拌合物性能试验方法标准》(GB/T 50080-2016)第5.1.3要求：“扩展度试验，应使用卷尺测量混凝土拌合物展开扩展面的最大直径以及与最大直径呈垂直方向的直径”，与扩展面最大直径垂直的直径，应当经过最大直径的中点。According to the requirements of Section 5.1.3 of "Standards for Performance Tests of Ordinary Concrete Mixtures" (GB/T 50080-2016): "In the expansion test, a tape measure should be used to measure the maximum diameter of the expansion surface of the concrete mixture and the distance between the maximum diameter and the maximum diameter." "Diameter in the perpendicular direction", the diameter perpendicular to the maximum diameter of the extension surface, shall pass through the midpoint of the maximum diameter.
工程实际测量混凝土扩展度时，通常采用卷尺测量混凝土扩展面的最大直径，根据记忆大致找出最大直径的中心点位置，将卷尺旋转90°，使卷尺经过最大直径的中点。When actually measuring the expansion of concrete in engineering, a tape measure is usually used to measure the maximum diameter of the concrete expansion surface, and the center point of the maximum diameter is roughly found according to memory, and the tape measure is rotated 90° so that the tape measure passes through the midpoint of the maximum diameter.
以上测量过程存在以下不足：由于只能通过目测将扩展面的边缘对应至卷尺的刻度，无法准确读数，因此，在测量与扩展面最大直径垂直的直径时，无法准确定位扩展面最大直径的中点位置；当测量扩展面最大直径时，卷尺的角度已经变化，凭记忆无法准确定位扩展面最大直径的中点。The above measurement process has the following disadvantages: since the edge of the expansion surface can only be visually matched to the scale of the tape, it cannot be read accurately. Therefore, when measuring the diameter perpendicular to the maximum diameter of the expansion surface, it is impossible to accurately locate the center of the maximum diameter of the expansion surface. Point position; when measuring the maximum diameter of the expansion surface, the angle of the tape measure has changed, and the midpoint of the maximum diameter of the expansion surface cannot be accurately located by memory.
