Abstract
The utility model relates to a ventilation engineering of architectural equipment specifically is a fire resistive construction of tuber pipe discharges fume, it is including the tuber pipe body of discharging fume that has finished through the support mounting, characterized by: still include PLASTIC LAMINATED, inlayer light gauge steel, outer light gauge steel and fire protection sealant, inlayer light gauge steel sets up around the tuber pipe body surface of discharging fume, and the PLASTIC LAMINATED wraps up on inlayer light gauge steel's surface, and seam crossing between PLASTIC LAMINATED and PLASTIC LAMINATED sets up fire protection sealant, sets up outer light gauge steel in the dog -ear department of PLASTIC LAMINATED. This fire resistive construction of tuber pipe discharges fume practicality is strong, has reduced the steel consumption and has changeed in the control fire -protection rating for current fire resistive construction of tuber pipe discharges fume with the installation degree of difficulty, ensures the quality of products.
Description
Technical field
The utility model is related to the ventilating engineering of Architectural Equipment, specifically a kind of fire proof construction of smoke exhaust pipe.
Background technology
Fire prevention airduct traditional structure be：In the outer layer of galvanized iron sheet airduct, square steel is installed, installs on square steel more afterwards
PLASTIC LAMINATED simultaneously is allowed to fix with square steel, although so the fire resistance rating of airduct can be lifted, increased the weight of airduct simultaneously
Measure, for no reason occupy larger space and the waste for material is also apparent from.
Content of the invention
The purpose of this utility model is, provides a kind of light structure and can effectively reduce the fire prevention airduct of waste of material
New structure.
In order to achieve the above object, the utility model is realized in：
A kind of fire proof construction of smoke exhaust pipe, it includes the smoke exhaust pipe body having installed by support, and it is special
Levying is：Also include PLASTIC LAMINATED, internal layer lightgage steel joist, outer layer lightgage steel joist and fireproof seal gum, internal layer lightgage steel joist is arranged on row
The surrounding of cigarette airduct body surface, PLASTIC LAMINATED is wrapped in the surface of internal layer lightgage steel joist, connecing between PLASTIC LAMINATED and PLASTIC LAMINATED
At seam, fireproof seal gum is set, outer layer lightgage steel joist is set at the knuckle of PLASTIC LAMINATED.
A kind of fire proof construction of described smoke exhaust pipe, PLASTIC LAMINATED is fastened even with internal layer lightgage steel joist by self-tapping screw
Connect.
The new structure of this fire prevention airduct is practical, reduces steel consumption amount and installation difficulty with respect to existing fire prevention
It is more easily controlled fire-protection rating it is ensured that quality for the structure of airduct.
Brief description
Fig. 1 is the sectional view of the new structure of this fire prevention airduct.
Specific embodiment
Further illustrate the utility model below by way of specific embodiment.
As shown in figure 1, a kind of new structure of fire prevention airduct, including galvanized iron sheet wind 6, PLASTIC LAMINATED 3, internal layer lightgage steel joist
2nd, outer layer lightgage steel joist 1 and fireproof seal gum 5, internal layer lightgage steel joist 2 is arranged on the surrounding arm of angle on smoke exhaust pipe body 6 surface
Edge, PLASTIC LAMINATED 3 is wrapped in the surface of galvanized iron sheet wind 6（Lightgage steel joist containing internal layer 2）, between PLASTIC LAMINATED 3 is connected with PLASTIC LAMINATED 3
Seam crossing setting fireproof seal gum 5, at the surrounding corner edge of PLASTIC LAMINATED 3 arrange outer layer lightgage steel joist 1.
A kind of fire proof construction of described smoke exhaust pipe, PLASTIC LAMINATED 3 is tight with internal layer lightgage steel joist 2 by self-tapping screw 4
It is solidly connected.
The new structure of this fire prevention airduct is practical, reduces steel consumption amount and installation difficulty with respect to existing fire prevention
It is more easily controlled fire-protection rating it is ensured that quality for the structure of airduct.
