Building Curtain Wall Wind Resistance And Debris Carrying Detection Equipment Execution Standard GBT29738-2013

【 Product Overview
This device is designed and developed in accordance with the new standard "Classification and Testing Method for Wind-carried Debris Impact Resistance of Building Curtain Walls and Doors and Windows" modified from foreign standards such as ASTM E1886-2005 and ASTM E1996-2008. It is a performance testing equipment for wind-carried debris impact resistance. The testing objects are limited to the specimens themselves of building curtain walls, exterior doors and Windows, and storm protection devices, and do not involve the connection parts between building curtain walls, exterior doors and Windows, and storm protection devices and other structures. This device is simply designed and easy to assemble. The pressure is adjustable and controllable, and the emission height is adjustable, which is convenient for experimental operation.

4. Requirements for steel balls: Mass 2g±0.1g, diameter 8mm;
5. Steel ball launch speed: 39.7m/s
6. Rated voltage of solenoid valve: AC 220V;
7. The detection device consists of the projectile, the launching device, the speed measurement device and the passive pressure box
8. The wooden blocks are made of pine or softwood, with a dry density of 500kg/m ³ ±25kg/m ³, a cross-sectional height of 38mm±1mm, and a width of 89mm±1mm. One end of the wooden block specimen is called the impact end, and the other end is the end.
【 Product Features
This device uses two photoelectric sensors of the same model and records the time it takes for the projectile to pass through the two sensors through an electronic timer. The response frequency of the electronic timer shall be no less than 10KHz, and the response time shall not exceed 0.15ms. The speed of the projectile is the calculated value of the distance between the two photoelectric sensors divided by the time recorded by the electronic timer.
