Abstract
The utility model discloses a power supply pipeline laying structure of a smoke exhaust fan for a profiled steel sheet roof, wherein a power supply threading pipe of the smoke exhaust fan, which is arranged in a hole of the profiled steel sheet roof, penetrates through a gap between the profiled steel sheet roof and a purlin, then extends into the hole for installing the smoke exhaust fan, and extends out of the side surface of the upper part of the hole and then is connected to a power supply point of the smoke exhaust fan. The power supply pipeline laying structure of the smoke exhaust fan for the profiled steel sheet roof directly utilizes the civil engineering opening of the roof smoke exhaust fan to lay the power supply pipeline without reserving a power supply sleeve on the roof, solves the technical defect of water prevention of the existing roof smoke exhaust fan power supply pipeline penetrating through the steel roof, realizes the standardization of pipeline and equipment installation, and achieves the effects of investment saving and convenient construction.
Description
Technical Field
The utility model relates to the technical field of laying of power supply pipelines of smoke exhaust fans, in particular to a laying structure of the power supply pipelines of the smoke exhaust fans for a profiled steel sheet roof.
Background
The profiled steel sheet roofing does not have waterproofing membrane, and the distribution pipe line of roofing smoke exhaust fan passes the waterproof of roofing and hardly does, consequently, how to do not have waterproofing membrane to the profiled steel sheet roofing, proposes the distribution pipe line of roofing smoke exhaust fan and lays to solve aforementioned waterproof problem, has important meaning.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a laying structure of a power supply pipeline of a smoke exhaust fan for a profiled steel sheet roof, aiming at the technical defects in the prior art, which can solve the waterproof technical defect of the existing steel roof through which the power supply pipeline of the smoke exhaust fan on the roof penetrates, realize the standardization of pipeline and equipment installation, and achieve the effects of saving investment and facilitating construction.
The technical scheme adopted for realizing the purpose of the utility model is as follows:
a power supply pipeline laying structure of a smoke exhaust fan for a profiled steel sheet roof is characterized in that a power supply threading pipe of the smoke exhaust fan, which is installed in a hole of the profiled steel sheet roof, penetrates through a gap between the profiled steel sheet roof and a purlin, extends into the hole for installing the smoke exhaust fan, and is connected to a power supply point of the smoke exhaust fan after extending out of the side face of the upper portion of the hole.
The power supply threading pipe is a wire pipe brushed with fireproof paint, and a galvanized steel pipe special for power distribution is adopted.
The hole is protruded upwards, the top end of the hole is away from a roof at a preset distance, the bottom of the smoke exhaust fan is supported at the upper end of the hole and is connected with the hole through a folded edge and a screw, and a fireproof flame-retardant damping pad is arranged between the bottom of the smoke exhaust fan and the upper end surface of the hole.
The bottom of the smoke exhaust fan is provided with a non-return air valve in the hole, and the power supply threading pipe penetrates upwards from a gap between the outer side of the non-return air valve and the inner wall surface of the hole.
And a reinforced steel beam is arranged at the bottom of the profiled steel sheet roof close to the opening and supports the profiled steel sheet roof.
The power supply pipeline laying structure of the smoke exhaust fan for the profiled steel sheet roof directly utilizes the civil engineering opening of the roof smoke exhaust fan to lay the power supply pipeline without reserving a power supply sleeve on the roof, solves the technical defect of water prevention of the existing roof smoke exhaust fan power supply pipeline penetrating through the steel roof, realizes the standardization of pipeline and equipment installation, and achieves the effects of investment saving and convenient construction.
Drawings
Fig. 1 is a schematic view of a power supply pipeline laying structure of a smoke exhaust fan for a profiled steel sheet roof according to an embodiment of the present invention.
Detailed Description
The utility model is described in further detail below with reference to the figures and specific examples. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
As shown in fig. 1, in the power supply pipeline laying structure of the smoke exhaust ventilator for the profiled steel sheet roof according to the embodiment of the present invention, the power supply threading pipe 6 directly penetrates through a gap between the profiled steel sheet roof 4 and the purlin 5, extends into the hole 10 where the smoke exhaust ventilator 1 is installed, and then is connected to the power supply point of the smoke exhaust ventilator 1.
The power supply threading pipe 6 is a wire pipe brushed with fireproof paint, and a galvanized steel pipe special for power distribution is adopted.
The hole 10 protrudes upwards from the roof, the top end of the hole is a preset distance away from the roof, the bottom of the smoke exhaust fan is supported at the upper end of the hole and is connected with the hole through a folded edge and a screw 3, and a fireproof flame-retardant damping pad 2 is arranged between the bottom of the smoke exhaust fan and the upper end surface of the hole.
The bottom of the smoke exhaust fan 1 is provided with a non-return air valve 9 in the hole 10, and the power supply threading pipe 6 penetrates upwards from a gap between the outer side of the non-return air valve 9 and the inner wall surface of the hole 10.
Wherein, the bottom of profiled sheet roofing 4 is nearly be provided with of entrance to a cave 10 and consolidate girder steel 7, it is right the profiled sheet roofing supports, consolidates the potential safety hazard that the girder steel can effectively avoid laying the cable and construct to the steel knot.
Wherein, a flue pipe fire damper 8 matched with a smoke exhaust fan can be arranged below the purline 5, as shown in fig. 1.
The power supply pipeline laying structure of the smoke exhaust fan for the profiled steel sheet roof directly utilizes the civil engineering opening of the roof smoke exhaust fan to lay the power supply pipeline without reserving a power supply sleeve on the roof, solves the technical defect of water prevention of the existing roof smoke exhaust fan power supply pipeline penetrating through the steel roof, realizes the standardization of pipeline and equipment installation, and achieves the effects of investment saving and convenient construction.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
