Welcome to Ji'nan Bojian Testing Machine Co., Ltd.

The test machine is mainly used to test the pressure test of anti static floor. It can measure the concentrated load, limit load, uniform load and other performance indexes of the anti static floor. This device can set the specified displacement displacement measurement force value, or set the specified force value to measure the change of displacement. The destructive pressure test can also be done directly, and the data of the instantaneous force values and the displacement data of the specimens are tested and recorded.

It mainly adopts the integrated structure of the brand high-performance motor and its drive system to drive the synchronous belt deceleration system, and then drives the screw pair to load after slowing down. The electrical part includes load measurement system and deformation measurement system. The device is fully controlled by the computer and displays the test curve in real time. It can edit and print test data report. It also has the function of limit protection, overload protection and so on.

The inspection of GB/T16825-1997 tensile testing machine is checked and checked.

Test method:

Test methods for concentrated load and limit load of floor.

Put the floor on the experimental equipment, adjust the four angle support to make the floor surface level, ensure that the four supports are simultaneously stressed.

1. specimens are placed to ensure that the force point is perpendicular to the floor plate, and the steel press head (No. 45 steel), which is 25.4mm, is placed in the central position of the measured floor to be compressed.

2. loading should be loaded slowly and continuously. After loading to the specified load value, the load should be loaded to 1min, and the load is added to 245N. The displacement sensor is cleared at this time.

3., when recording load and displacement curve, slow and even loading should be used, and loading speed should be controlled at about 1000N/min. After loading to the specified load value, record the deflection value of the bottom floor of the floor, then record the permanent deformation of the floor when unloading to pre load 245N.

4., slow and continuous uniform loading is used for concentrated loading. Until the floor is destroyed. (when the floor cracks, or the load displacement occurs, the collapse is broken.

Uniform load test method for flooring:

According to the following chart, the test method of the floor uniform load is carried out. The pressure block is placed in the illustrated position and loaded according to the loading mode of the concentrated load, until the value of the floor deflection exceeds the allowable value, that is, the average load value. Uniform load = floor load value / floor area when floor deflection exceeds allowable value.
