Description

Product Introduction:

Applicable to the testing of wind-pressure resistance performance of exterior wall external thermal insulation materials adhered to the base wall.

Reference standard:

JGJ 144-2019 Technical Code for Exterior Wall External Thermal Insulation Engineering

JG/T 149-2003 “Exterior Wall External Thermal Insulation System with Expanded Polystyrene Boards and Thin Plaster Finish”

JG/T 158-2013 “Materials for Exterior Wall External Thermal Insulation Systems Composed of Rubber Powder and Expanded Polystyrene Granules”

GB/T 36585-2018 “Test Method for Dynamic Wind Pressure on External Wall External Thermal Insulation Systems”

Product Features:

1. Computer control system and its console: primarily composed of electrical components, a microcomputer system, instruments, pushbuttons, and other automatic and electrical control elements.

2. Negative-pressure chamber: It mainly consists of a negative-pressure mounting box, mounting fixtures, an internal illumination system, a differential pressure transmitter, and pressure-sensing tubing, among other components.

3. Variable-frequency fan and pressure-regulating system: primarily composed of a high-pressure centrifugal fan, an AC variable-frequency drive, a power supply and control board, and a brake.

4. Piping and Pulsation Pressure System: Primarily composed of 160 mm-diameter piping, pipe fittings, pneumatic pulsation valves, an air pump, and two‑position three‑way valves, among other components.

5. Specimen frame: Primarily fabricated by welding together 14# channel steel, Φ12 threaded steel bars, lifting rings, and support pivots. It is used for casting concrete specimen walls; the standard configuration includes two specimen frames, allowing one to be in use while the other is employed for preparing and curing the external thermal insulation system.
