Abstract

The invention discloses a non-nail connection combined fire-proof exhaust duct and a producing method thereof. The non-nail connection combined fire-proof exhaust duct is formed in a manner that a plurality of fire-proof slabs are cut to have meshing structures at connecting positions at the lateral end according to the size required by design requirements, the corresponding meshing structures of the slabs are butted and fitted, and adhesive is coated on the connecting positions. According to the novel connecting technique, the combined fire-proof box exhaust duct overcomes the fatal defects that traditional nail connection combined fire-proof exhaust ducts in the market are not corrosion resistant, not durable, and the whole flue may cause smoke leakage or falling apart. The combined fire-proof exhaust duct in the novel connecting technique is resistant to corrosion due to SO2, CO2, H2O (vapor) and free C1- ions, safe, reliable and long in service life, and the product quality conforms to national standards. Besides, the connecting technique can also be applied to parallelly connecting small fire-proof slabs into large ire-proof slabs.

Description

technical field [0001] The present invention relates to a box body flue exhaust duct or other exhaust ducts made of fireproof materials, especially a fireproof box body flue exhaust duct or other various box bodies and kitchen flues made of several pieces of fireproof boards using a nail-free joining process , Air conditioning exhaust pipe, elevator exhaust duct, toilet exhaust duct and enterprise workshop exhaust duct. Background technique [0002] Glass magnesium fireproof board has the characteristics of high mechanical strength, fire prevention, water resistance, energy saving, environmental protection, can be sawed, nailed, and reprocessed. In fact, this kind of board belongs to the category of magnesite cement products. The product development of my country's magnesite industry has experienced several ups and downs. As early as the 1950s, my country started the development and utilization of magnesite resources. Due to the limitation of production conditions and techn...
