Construction points:
1. Glass bricks should be masonry built with two reinforced f6-f8 reinforcements. The base height should not exceed 150mm and the width should be more than 20mm above the glass brick thickness.
2. The application of metal profiles at the top and the ends of the glass brick partition wall should be greater than the brick thickness 10~18mm.
3. When the length or height of the partition is greater than 1500mm, install a steel bar every two layers in the vertical direction (when the length and height are all more than 1500mm, set two steel bars); set one steel bar every three vertical seams in the horizontal direction. . Rebar extends not less than 35mm into the slot. The height of glass blocks reinforced with reinforced steel shall not exceed 4m.
4. The two ends of the glass partition wall and the two sides of the metal profile shall have a slide joint with a width of not less than 4mm, and the joint shall be filled with linoleum; the glass partition plate and the belly side of the profile shall have expansion joints with a width of not less than 10mm to avoid the glass brick partition wall. damage.
5. The top brick of the glass brick should extend into the top metal profile slot 10~25mm, so as to avoid the broken glass brick due to rigid extrusion.
6. The seams between glass tiles must not be less than 10mm and not more than 30mm.
7. The joints between glass tiles and profiles, profiles and buildings shall be sealed with an elastic sealant.

The vibration sensor(Vibration Transmitter) is one of the key components in the testing technology of Vibration Measurement. Its main function is to receive the mechanical quantity and convert it into a proportional electric quantity. Because it is also an electromechanical conversion device. So we sometimes call it a transducer, a vibration pickup, etc.
Commonly used vibration sensors are as follows:
1. Piezoelectric resonant
The piezoelectric sheet is used to receive the vibration signal, and the resonance frequency of the piezoelectric sheet is relatively high. In order to reduce the resonance frequency, it is realized by increasing the mass of the piezoelectric sheet vibrating body, and using a spring ball instead of an appendage to reduce the two resonance frequencies and enhance the vibration effect. Its advantages are high sensitivity and simple structure. However, the signal needs to be amplified and sent to a TTL circuit or a single-chip microcomputer circuit, but it is enough to use a triode single-stage amplification
2. mechanical vibration
In the traditional vibration detection method, after being vibrated, the spring ball vibrates at a reduced amplitude for a long time, and this vibration is easy to be detected by the detection circuit. The vibration output switch signal is determined by the output impedance and the resistance value of the matching output. According to the input impedance of the detection circuit, it can be made into a high-impedance output mode.
3. Micro Vibration Sensor
The mechanical vibration sensor is miniaturized, the vibration body is carbonized and sealed, and its working performance is more reliable. The output switching signal is directly connected with the TTL circuit and or the input circuit of the single-chip microcomputer, and the circuit structure is simple. The output impedance is high, and the quiescent working current is small.
Advantages of Vibration Sensors
1. Small size and light weight. It can be applied to some vibration test systems that are greatly affected by the additional mass.
2. It has a wider response frequency range of 4Hz-2000Hz than the magnetoelectric speed sensor, and the mechanical moving parts are not easy to damage
