2. The column height is 3600~5300mm, the fire height is 3000~4700mm, and the fire resistance test of the steel structure column with a protective layer (fireproof coating) is subjected to various cross-sectional shapes and sizes of single and multiple composite loads.

3. Temperature determination of selected measurement points with different sections and different depths inside the column.

4. Fire resistance test of other items (such as safes) that are on fire on all sides.

Intelligent test device for fire resistance performance of fire damper. The configurations we provide below are for reference only;

Scope of application: It is suitable for load-bearing and non-load-bearing components such as walls, beams, columns, floor, ceilings and roofs, and other structures, accessories or structures can be used as references. This testing machine is suitable for the test of all components of GB/T9978.1~9 and ISO834-1~9 standards.

=Conform to standards: GB/T9978.1-2008, GB/T9978.2-2008, GB/T9978.3-2008 "Fire Resistance Test Methods for Building Components Part I: General Requirements", ISO834-1:1999 "Fire Resistance Test Building Components Part I: General Requirements"

Main parameters:

Laboratory: 4.5M(length)x4.5M(width)x3.5M(height), the indoor use of high temperature insulation materials.

Loading device: Mechanical loading is adopted to move the overhead crane in the building. Homogeneous, central, pivotal, or eccentric loading can be simulated.

Supporting frame: connected to a wedge bracket on the frame by four rollers.

Thermocouples: including furnace thermocouples, backside heat couples, mobile thermocouples, internal thermocouples, and ambient temperature thermocouples are distributed in various areas.

Furnace pressure measurement probe: T-shaped measuring probe, measurement accuracy ± 2Pa

Specimen gap measuring probe: 6mm diameter ± 0.1mm diameter ±0.2mm diameter

Combustion system: gas distribution system (within 10 meters), flamethrower (not less than 20) and regulating valves

Combustion gas source: propane with purity of more than 95%, liquefied gas (provided by the user)

Gas flow: 0~100L/min Measurement accuracy 2.5 grade

Air flow: 0~50m3/min Measurement accuracy≤±0.5m3/min

Gas tank capacity: ≥50kg×6

Furnace temperature control system: the maximum sampling point is 10 points

ventilation system and control damper, etc

Measuring range of radiant heat on the backfire surface of the specimen: 0~10W/cm2

The temperature and pressure control in the furnace is realized by connecting the RS485 of the computer to the control system, and the DC output voltage of the combustion test sensors such as thermocouples and pressure sensors is converted into digital form, which can then be transmitted to the computer system for display and storage.
