Problems solved by technology
[0004] At present, there are still very few testing instruments for measuring the anti-skid performance of building floors in my country, and there is no unified regulation on the evaluation standards and technologies for the anti-skid performance of the ground, which has caused many difficulties and problems in actual operation.

Embodiment Construction
[0017] Such as Figure 1-Figure 5 As shown, the present invention is mainly made up of base 14, support 16, friction slider 2, sleeve 8 with scale, guide rail 18, spring 10 and force applying device.
[0018] exist figure 2 , Figure 4 and Figure 5 Among them, the rubber block 13 is placed in the concave hole of the friction slider 2. According to the needs of different test conditions, the rubber block 13 can also be easily replaced with other friction materials, such as leather, Naolite, etc. The baffle plate 1 is to keep the friction slider 2 sliding in a straight line. The spring 10 is placed in the sleeve 8 , one end is fixedly connected with the sleeve 8 , and the other end is connected with the friction slider 2 through the connecting rod 17 . The bracket 16 is fixedly installed on the base 14, and the bracket 16 is provided with a guide rail 18, the sleeve 8 is placed in the guide rail 18, the sleeve 8 and the guide rail 18 form a sliding fit, and the upper surfa...

The invention discloses a mechanical building ground anti-skidding performance tester, mainly comprising a pedestal, a bracket, a friction slip, a graduated sleeve and a spring, the bracket is fixedly installed on the pedestal, a guide rail is arranged on the bracket, the sleeve is arranged in the guide rail, the sleeve and the guide rail form sliding fit, the spring is arranged in the sleeve, and one end of the spring is fixedly linked with the sleeve while the other end of which is connected with the friction slip through a connecting rod. In the mechanical building ground anti-skidding performance tester, the sleeve is moved so as to extend the spring, until the friction slip slides, and finally a frictional factor can be solved through a displacement value. With the tester, the frictional factor of the building ground can be conveniently tested so as to provide basis for estimating ground anti-skidding performance, simultaneously, the mechanical building ground anti-skidding performance tester is featured by clear and understandable principle, simple structure and convenient operation, and both can be used in a laboratory and at site.
Description
technical field [0001] The invention relates to a detection instrument, in particular to an instrument for measuring the anti-skid performance of the ground. Background technique [0002] Most economically developed areas and densely populated areas in my country are in the subtropical climate zone, which is warm, humid and rainy all year round. No matter at home or in commercial places or other public places, when it rains, after cleaning, in wet seasons or when bathing, the anti-skid performance of the ground will drop sharply, often causing slipping, falling accidents, and even serious casualties. Every year, the number of people injured due to slippery ground in our country is on the rise. Every day, tens of thousands of people are injured due to slipping and falling. The problem of ground anti-skid safety has become a new issue of public safety. [0003] Evaluating the anti-skid performance of the ground is generally achieved by measuring the coefficient of friction be...
