Detailed Description
In order to make the objects, technical solutions and advantageous effects of the present utility model more apparent, preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding of the skilled person.
As shown in fig. 1, the concrete elastic modulus positioning scriber comprises a handle 1, a fixing rod and a frame 4, wherein the frame 4 is of a rectangular structure, scale marks are arranged on the four sides of the frame 4, the handle 1 is arranged at the center inside the frame 4, the longitudinal fixing rod 5 is symmetrically arranged on the frame 4 along the handle 1, the transverse fixing rod 3 perpendicular to the longitudinal fixing rod 5 is arranged at the transverse center of the longitudinal frame 4, and positioning hole rings 2 corresponding to each other are formed in the overlapping positions of the transverse fixing rod 3 and the longitudinal fixing rod 5.
In this embodiment, the frame 4 is made of a metal material with a hard texture and is not easily deformed. The bottom surface is smooth, and the flatness is not more than 0.02mm per 100 mm. The whole rule width is 20mm, and the thickness is 2mm. The structure is as follows: the whole appearance is made of metal which is hard in material and not easy to deform. The design of the frame considers the allowable deviation of the size of a test piece, and the 3.3.2 rule of the 'standard for testing the physical and mechanical properties of concrete' GB/T50081-2019: the size tolerance of the side length, the diameter and the height of the test piece is not more than 1mm; provision in clause 3.3.4: the included angle between the adjacent surfaces of the test piece is 90 degrees, and the tolerance of the included angle is not more than 0.5 degrees, so that the outer frame is designed to be 301mm long by 151mm wide, and the included angle is 90 degrees. The frame is provided with scales, and the graduation value is 0.5mm. The middle points of the long side and the short side of the outer frame are 0 scale marks, the outer frame extends to two sides respectively, the transverse fixing rods 3 and the longitudinal fixing rods 5 are arranged in a staggered mode, are double-field-shaped and are connected with the frame 4, and the middle cross point of the double-field-shaped fixing rods is a positioning hole circular ring 2, and the outer diameter is 10mm multiplied by the inner diameter is 2mm. The distance between the center points of the two positioning hole circular rings 2 is 150mm.
The application method of the utility model comprises the following steps: the frame 4 is horizontally placed on the side face of the test piece and is tightly attached to the side face of the test piece, scales of short sides on two sides of the frame 4 are equal, scales of long sides on two sides of the frame are equal, a marker pen or other streakable pens are adopted to mark positioning points on the test piece at the positioning hole ring 2, the test piece is turned over, the 4 side faces of the test piece are marked with positioning points, the elastic modulus tester is arranged on the test piece, 8 test piece fastening screws are overlapped with the marked positioning points, and finally the screws are screwed.
