Description

Technical Field

[0001] The utility model relates to the technical field of mortar performance detection tools, and more specifically, to a tool for quantitatively characterizing the performance of mortar. Background Technique

[0002] Mortar is an adhesive substance used for bricklaying in construction. It is made by mixing a certain proportion of sand and cementitious materials (such as cement, lime paste, clay, etc.) with water. It is also called mortar. Commonly used mortars include cement mortar, mixed mortar (or cement-lime mortar), lime mortar, and clay mortar. The excellent workability of mortar, commonly known as good state, characterizes various properties of the mixture.

[0003] A mortar consistency meter is also called a mortar fluidity tester, which is an instrument for measuring the fluidity performance of mortar. It mainly consists of a cone (with a height of 145 mm, a bottom diameter of 75 mm, and a weight of 300 ± 2 g) with a sliding rod and a frustum-shaped metal cylinder container. The well-stirred mortar is filled into the container at one time until it is about 1 cm away from the upper mouth of the container and tamped according to the specified test method. Then the cone is allowed to freely sink from the center of the mortar surface. After 10 s, the falling distance is measured and read, in cm (accurate to 0.5 cm), which is the consistency value (also called the penetration depth) of the mortar.

[0004] However, when the existing mortar consistency meter detects the consistency of mortar, the connection part between the connecting shaft rod of the mortar test cone and the bracket of the mortar consistency meter is static friction. Therefore, during the free fall of the mortar test cone, the friction generated by the static friction is relatively large, which affects the detection accuracy of the mortar consistency. So we propose a tool for quantitatively characterizing the performance of mortar to solve the above problems. Content of the Utility Model

[0010] A connecting shaft rod is arranged between the guiding grooves, and the outer wall of the connecting shaft rod is in contact with the rubber sleeve. The bottom end of the connecting shaft rod is connected with a mortar test cone located above the mortar holding bucket;

A guide groove 6 is annularly arranged in the middle of the outer wall of the shaft head 8, and a rubber sleeve 7 is sleeved outside the guide groove 6;

[0031] A connecting shaft rod 9 is arranged between the guide grooves 6, and the outer wall of the connecting shaft rod 9 is in contact with the rubber sleeve 7. The bottom end of the connecting shaft rod 9 is connected to a mortar cone 10 located above the mortar holding bucket 2;

[0032] Above the roller 5, a positioning bolt 14 screwed to the guide seat 4 is provided, and the positioning bolt 14 abuts against the connecting shaft rod 9;

[0033] It should be noted that when using this tool for quantitatively characterizing the properties of mortar, an appropriate amount of uniformly stirred mortar to be tested is added inside the mortar holding bucket 2, and then the top of the mortar is leveled;

[0034] Place the connecting shaft rod 9 inside the guide seat 4, guide the connecting shaft rod 9 through the guide groove 6 provided on the outer wall of the roller 5, and use the rubber sleeve 7 to fit with the connecting shaft rod 9 to ensure the stability of guiding the connecting shaft rod 9. Then adjust the position of the mortar cone 10 so that its tip is flush with the top horizontal surface of the mortar. Then rotate the positioning bolt 14 to position the connecting shaft rod 9. After adjusting the position of the measuring gauge 3, loosen the positioning bolt 14 to make the mortar cone 10 drop. At the same time, guide the connecting shaft rod 9 by rotating the roller 5, reducing the resistance of the mortar cone 10 during the descending process. Then use the measuring gauge 3 to detect the consistency of the mortar, thereby ensuring the detection accuracy of the mortar consistency.

[0035] Such as Figure 1 、 Figure 4 As shown in the figure, butterfly bolts 12 are symmetrically screwed on the edge part of the upper surface of the base 1, and the butterfly bolts 12 penetrate through the base 1. A cushion block 11 is fixedly connected to the edge part of the lower surface of the base 1, and the lower surface of the cushion block 11 is on the same horizontal plane as the bottom end of the butterfly bolt 12. A spirit level 13 is installed on the edge part of the upper surface of the base 1 away from the cushion block 11;

[0040] It should be noted that during the descending process of the mortar cone 10, the tip of the mortar cone 10 is prevented from colliding with the inner wall of the mortar holding bucket 2 to ensure the test result of the mortar consistency.

[0041] As Figure 2 , Figure 3 shown, the spacing between the guide grooves 6 is adapted to the outer diameter of the connecting shaft rod 9;

[0042] It should be noted that during the falling process of the mortar cone 10, the connecting shaft rod 9 is guided by the rotation of the roller 5, and the resistance of the mortar cone 10 during the falling process is reduced through rolling friction.

[0043] In use: An appropriate amount of uniformly stirred mortar to be tested is added inside the mortar storage bucket 2, and then the top of the mortar is leveled.

The connecting shaft rod 9 is guided by the guide grooves 6 provided on the outer wall of the roller 5, and the rubber sleeve 7 is used to fit with the connecting shaft rod 9 to ensure the stability of guiding the connecting shaft rod 9. Then, the position of the mortar cone 10 is adjusted so that its tip is flush with the top horizontal plane of the mortar. Then, the positioning bolt 14 is rotated to position the connecting shaft rod 9. After adjusting the position of the measuring gauge 3, by loosening the positioning bolt 14, the mortar cone 10 falls, and at the same time, the connecting shaft rod 9 is guided by the rotation of the roller 5, reducing the resistance of the mortar cone 10 during the falling process. Then, the consistency of the mortar is detected by using the measuring gauge 3.
