The invention discloses an environment-friendly suspended ceiling mounting structure with a refractory brick. The environment-friendly suspended ceiling mounting structure comprises the refractory brick (1) and a square tube (2), the refractory brick (1) is connected with the square tube (2) through a custom-made suspension piece (3), and the square tube (2) is fixed to a suspended ceiling keel. The section of the custom-made suspension piece (3) is in a U shape, the custom-made suspension piece (3) covers the square tube (2) from the outer side and extends to the refractory brick (1), threaded holes are formed in the custom-made suspension piece (3), and the custom-made suspension piece (3) fixes the square tube (2) and the refractory brick (1) through screws and caps. The refractory brick can be applied to the field of the suspended ceiling, and the application of environment-friendly materials is widened. Batch production can be achieved to improve benefits, comprehensive cost is saved, high-quality productization decoration is implemented, and green engineering is constructed. Large-batch production of factories can be achieved to achieve the productization decoration concept, construction cost and environmental pollution can be effectively lowered, and the modern decoration aethestic standard is met.
