Abstract
The utility model provides a kind of sealing, fireproof air-conditioner air supply device, it includes square airduct main body, airduct main body madial wall is coated with fireproof coating layer, airduct main body lateral wall is coated with flame retardant coating, turn round into hook again after the outside flanging of airduct body end, the straight flange edge inwall of described hook is 45 ° of hypotenuses; The flanging of airduct body end corner is cut into hypotenuse and point forms straight line connection bit centered by airduct main body corner; Flanging between adjacent airduct main body is connected by connection strap; Connection strap main body is made up of rectangle pipe, one of them side cut-away grooving of rectangle pipe, and the side of groove both sides is to tube cavity bending button limit at 45 °; Hook after fastening and button limit are close to.This programme adopts assembly type intercalation structure, namely ensures ventilation duct bonding strength, reduces labour intensity, saves operating expenses, can prevent fires again, strengthens use safety.
Description
Technical field
The utility model relates to air-conditioning, refers in particular to a kind of sealing, fireproof air-conditioner air supply device.
Background technology
Air-conditioning refers to uses artificial means, the parameter such as temperature, humidity, cleanliness factor, speed of building/structures environment air is carried out to the process of regulation and control.It is made up of cold and heat source system and air handling system.The principle of vaporizing liquid refrigeration is adopted to provide institute's chilling requirement, in order to offset the refrigeration duty of indoor environment for air handling system; Heating provides the heat of offsetting indoor environment thermic load for air handling system.Existing air-conditioning is in the syndeton of ventilation shaft port, and multiplex angle iron flange or punch forming flange are connected to the port of ventilation duct, then is docked by the flange of ventilation duct by the mode of screw fastening, adopts this process method construction efficiency low and costly.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of structure is simple, easy to operate, the air-conditioner air supply device of good airproof performance, fireproofing and heat resistant.
For achieving the above object, technical scheme provided by the utility model is: a kind of sealing, fireproof air-conditioner air supply device, it includes square airduct main body, airduct main body madial wall is coated with fireproof coating layer, airduct main body lateral wall is coated with flame retardant coating, turn round into hook again after the outside flanging of airduct body end, the straight flange edge inwall of described hook is 45 ° of hypotenuses; The flanging of airduct body end corner is cut into hypotenuse and point forms straight line connection bit centered by airduct main body corner; Flanging between adjacent airduct main body is connected by connection strap; Connection strap main body is made up of rectangle pipe, one of them side cut-away grooving of rectangle pipe, and the side of groove both sides is to tube cavity bending button limit at 45 °; Hook after fastening and button limit are close to; Hook and detain the joint clearance place on limit by injecting glue or the sealing of packing strip of paper used for sealing.
The flanging end of described airduct main body is provided with elastic sealing gasket.
The utility model has the advantage of: adopt assembly type intercalation structure, namely ensure ventilation duct bonding strength, reduce labour intensity, save operating expenses, namely fireproof coating and flame retardant coating can be incubated, and prevent heat energy from spreading, and can prevent fires again, strengthen use safety.
