New elastic modulus tester for concrete test block

Abstract

The invention provides a new elastic modulus tester for a concrete test block. A lower mounting plate and an upper mounting plate are coaxially fixed on the lower end and the upper end of the concretetest block respectively. Fastening screws are arranged on the lower mounting plate and the upper mounting plate respectively, and are tightly fixed with the outer wall of the concrete test block. A tester mounting seat is installed on the upper mounting plate, and a microdeformation detector is mounted on the tester mounting seat. The end part of a lower vernier and the side wall of the lower mounting plate are provided with a plug and a jack which are matched for plug-in connection. The end part of an upper vernier and the side wall of the upper mounting plate are provided with a plug and ajack which are matched for plug-in connection. A ruler body is penetrated and inserted in the lower vernier and the upper vernier in turn. The lower vernier and the upper vernier are respectively provided with vernier fastening screws. One ends of the vernier fastening screws pass through the side walls of one sides of the lower vernier and the upper vernier to cooperatively clamp the ruler body.The end parts of the lower vernier and the upper vernier arranged up and down are respectively fixedly cooperatively connected with the lower mounting plate and the upper mounting plate, so that the height can be adjusted at random on a height ruler by the lower mounting plate and the upper mounting plate, and the detection range can be adjusted at random.

Description

technical field [0001] The invention relates to a novel concrete test block elastic modulus measuring instrument. Background technique [0002] Currently used concrete test block elastic modulus tester such as figure 1 As shown, it consists of a lower mounting plate 1, a set screw 2, an upper mounting plate 3, a detector mounting seat 4, a micro-deformation detector 5, a tightening bolt 6 and a spacer 7. its top view see figure 2 , and the test block in the middle (rectangular test block in the figure). The current basic practice is: the size of the rectangular test block: length X width X height is 150X150X300. First use the altimeter on the concrete test block according to the image 3 For the dimensions shown, draw the location line. Insert the lower mounting plate 1 into the outside of the concrete test block, align the set screw 2 with the center of the cross drawn on the positioning line and tighten it. When tightening, ensure that the lower mounting plate 1 coin...

AI Technical Summary

Problems solved by technology

[0004] The existing problems of the elastic modulus tester are as follows: 1) all parts of the elastic modulus tester are separated, and each test must be installed one by one, which wastes a lot of time; 2) because the upper and lower mounting plates do not have a fixed relative position , before installation, you must draw a line on the test block to determine the installation anchor point
