Inspection and requirements of frameless fireproof glass in engineering application

2020-03-09 2025

The fire-resistant function of frameless fire-proof glass for building is obtained by directly inlaying frameless fire-proof glass in the wall hole or combined with the structure, and then inlaying it in the wall hole to make components according to gbl2513. It includes the determination of fire-resistant integrity, fire-resistant heat insulation and thermal radiation intensity. Meanwhile, the measurement of thermal insulation is based on the back fire surface temperature.

Fire resistance and thermal insulation refers to the temperature rise of single point at the temperature measuring point on the back fire surface of the test piece of 180 ℃ and uniform temperature rise of 140 ℃.

Thermal radiation intensity refers to the critical radiant heat illuminance reaching 0.42w/cm2 at 3M from the back fire surface of the test piece, and the critical radiant heat illuminance reaching 3.35 w / cm2 at a distance equal to 1.2 times its smaller standard (length or width). Fire resistance function test: the whole frameless fireproof glass shall be embedded in the fixed structure, and the fire resistance function test shall be carried out according to gb12513. The fire standard height of frameless fireproof glass shall not be less than 1100mm, the width shall not be less than 600mm, and the sample shall be vertical to the equipment. The fixed structure and equipment method used in the test shall be the same as that used in practical engineering, and the structure and equipment method of fixed structure shall be recorded in the method of drawings.

Bending test: place the glass vertically, place a ruler horizontally close to the surface of the sample for measurement, and indicate it in the percentage of the ratio of the height of the arc to the length of the chord when it is arched; The waveform is indicated by the percentage of the ratio of the height from trough to peak to the distance from peak to peak (or trough to trough). The products shall be packed in wooden cases or other packing boxes. The glass shall be placed vertically in the box. Each glass shall be wrapped with plastic cloth or paper. The light and soft materials that are not easy to cause glass scratches and other appearance defects shall be used between the glass and the packing box.
