Description

Technical Field

[0001] The invention belongs to a building smoke prevention and exhaust system, and in particular relates to a smoke supply and exhaust pipeline structure of the smoke prevention and exhaust system and an installation method thereof. Background Art

[0002] Traditional vertical air supply ducts or smoke exhaust ducts of building smoke exhaust systems are mostly built around the reserved holes on the top of each floor to the bottom of the upper beam or slab to form civil air ducts. During the masonry process, the expansion coefficients of the blocks and concrete wall materials are often different, resulting in structural cracks between the blocks and the shear wall; the mortar between the blocks is not full, resulting in gaps between the blocks; the masonry is not standardized, resulting in the blocks not biting each other at the corners of the well, forming through seams; the setting or number of tie bars is unqualified, resulting in gaps after the wall is deformed. All of the above reasons lead to poor tightness of the civil air duct and large air leakage.

[0003] In addition, the inner wall space of the civil engineering air duct is small, and plastering is difficult, and often no plastering or partial plastering occurs. Even if plastering is performed, it is impossible to achieve a smooth and flat plastering surface. Therefore, the resistance along the civil engineering air duct is large.

[0004] Due to the poor tightness of civil engineering air ducts and the large resistance along the way, the cross-sectional area of ​​the building smoke exhaust system air duct design must be increased. When selecting fans, the flow rate, total pressure indicators and fan power must all be increased, resulting in increased system construction costs and operating costs. In particularly serious cases, the smoke exhaust system will lose its function, causing significant losses and threats to national property and people's lives.

[0005] The traditional vertical smoke supply and exhaust duct structure in current buildings is basically the same as the general rectangular metal ventilation duct. The construction method is prefabrication in the factory or processing area and on-site assembly. Because vertical smoke supply and exhaust ducts are mostly arranged at the corners of two mutually perpendicular shear walls and have a large length and width ratio, when assembling the duct sections, the flange connection bolts on one side of the shear wall that are more than 500 mm from the outside to the inside are left empty because they are beyond the reach of the operator's arm, causing the problem of air leakage in the smoke supply and exhaust ducts to still exist; in addition, in order to reserve operating space and fix the load-bearing bracket, when the air duct is installed along the wall, it is necessary to leave more than 200 mm from the wall surface. Fig.10 Therefore, compared with the civil construction air duct, this type of smoke supply and exhaust duct, in addition to reducing the medium resistance along the way, is still not very tight, and each side consumes more than 200 mm of building space, which not only causes certain difficulties in building design, but also occupies the effective use space of the building and increases the construction cost.

The pressing plate pressing block 14 is arranged along the length direction of the pressing plate part 13. The pressing plate pressing block 14 is pressed against the surface of the pressing plate part 13 by bolts, so that the pressing plate part 13 is fixedly connected to the rear panel 2 and the shear wall 1.

[0043] An overlap portion 7 is provided at the upper end or the lower end of the rear panel 2, and the overlap portion 7 is a bent structure. During the installation and fixing process of the upper and lower adjacent rear panels 2, the overlap portion 7 is adopted in the direction of wind to reduce air leakage or smoke leakage; specifically, during the installation process, the overlap portion 7 of one of the two adjacent rear panels 2 is overlapped at one end of the other rear panel 2; for the mechanical pressurized air supply and smoke prevention system, because the medium in the pipe flows from top to bottom, the overlap portion 7 of the rear panel 2 at the upper end is overlapped on the rear panel 2 at the lower end; for the mechanical smoke exhaust system, because the medium in the pipe flows from bottom to top, the overlap portion 7 of the rear panel 2 at the lower end is overlapped on the rear panel 2 at the upper end; a sealing gasket 8 is provided between the overlapping parts of the two rear panels 2, and a lap seam pressing block 9 is provided at the upper end of the overlapping parts of the two rear panels 2 for pressing the overlapping parts of the two rear panels 2, and the overlapping parts of the two rear panels 2 are fixed to the shear wall 1 by expansion bolts.

[0044] A connecting flange 10 is fixed to the outside of the front panel 5, which is flush with the upper and lower end faces of the front panel 5. During the installation process, the upper and lower adjacent front panels 5 are fixedly connected by the connecting flange 10, and a flange sealing gasket 11 is provided between the two connecting flanges 10. The two connecting flanges are fixedly connected by fastening bolts 12 to achieve a horizontal connection between the two front panels 5; the connecting flange 10 is prefabricated on the front panel 5 or the connecting flange is riveted to the front panel 5; the connecting flange 10 is an L-shaped structure, one side of the connecting flange 10 is fixedly connected to the outer side surface of the front panel 5, and the other side of the connecting flange 10 is parallel to the end of the front panel 5, so that the two front panels 5 are conveniently fixedly connected by the connecting flange 10.

[0045] The end of the connecting flange 10 is provided with a fixing foot 12, which is fixedly connected to the shear wall 1 by bolts to transfer the weight of the front panel 5 to the shear wall. The plane where the largest surface of the fixing foot 12 is located is perpendicular to the plane where the largest surface of the connecting flange 10 is located.

[0046] It also includes a through-thread screw 17 for reinforcing the front panel 5. A through hole coaxial with the fixing hole of the shear wall 1 is opened in the middle of the front panel 5 and the rear panel 2. An expansion bolt 15 is arranged in the fixing hole of the shear wall 1. One end of the through-thread screw 17 is fixedly connected to the internal thread hole of the expansion bolt 15. One end of the through-thread screw 17 is fixed to the shear wall 1 through the expansion bolt 15. The other end of the through-thread screw 17 passes through the flue formed by the rear panel 2 and the front panel 5. The outer side of the rear panel 2 is fixed to the through-thread screw 17 through a nut 16, and both sides of the front panel 5 are fixed to the through-thread screw 17 through the nut 16; thereby, the stability of the front panel 5 is enhanced; the through-thread screw 17 is locked with the rear panel 2 through a nut, a washer is arranged between the nut and the rear panel 2, and the through-thread screw 17 is locked with the front panel 5 through a nut, and a washer is arranged between the nut and the front panel 5.

[0047] For multi-layer floor structures, each floor is provided with a reserved channel 6, and the rear panel 2 and the front panel 5 both pass through the reserved channel 6. The side of the front panel 5 and the side wall of the reserved channel 6 of the floor are sealed by fireproof mud. The rear panel 2 and the front panel 5 on the multi-layer floor are continuously connected, and there is no need to specially set the height of the rear panel 2 and the front panel 5 for a specific height. The rear panel 2 and the front panel 5 have strong versatility, and the problem of sealing the rear panel 2 and the front panel 5 at the upper end of each layer with the floor is avoided, thereby improving the sealing of the rear panel 2 and the front panel 5.

[0048] It also includes a support base 4 for adjusting the support height of the front panel 5. The support base 4 includes a base 18 and a screw rod 20 that is an integral structure with the base 18. An adjusting nut 19 is provided at the upper end of the screw rod 20. During use, the front panel 5 needs to be supported. The base 18 is set on the upper surface of the floor slab of this layer, so that the screw rod 20 on the base 18 is aligned with the flange body of the lowest front panel 5 on the floor slab of this layer. The adjusting nut 19 on the screw 20 is adjusted to contact and support the flange body of the front panel 5. The supporting force on the screw 20 is directly applied to the connecting flange of the front panel 5, forming a bottom supporting structure for each layer, which can not only bear the dead weight of the smoke exhaust pipe on each layer, but also adjust the horizontality of the connecting flange.

[0052] Step 3), finally, the fixing feet 12 of all the connecting flanges 10 are fixedly connected to the shear wall 1 by bolts.

[0053] For a multi-layer floor structure, a support seat 4 is set on each floor layer, and the base 18 of the support seat 4 is set on the bottom surface of the floor layer. The screw 20 on the base 18 is adjusted to be aligned with the flange body of the lowest front panel 5 on the floor layer, and the adjusting nut 19 on the screw 20 is adjusted to contact and support the flange body of the front panel 5 to form a bottom support structure for each layer.

[0054] In step 1), fireproof glue is applied to the outer side of the rear panel 2 before the rear panel 2 is fixed to the shear wall 1, which not only improves the connection strength between the rear panel and the shear wall, but also increases the tightness of the connection between the rear panel and the shear wall, thereby reducing the noise of pipeline operation.

[0055] In step 1), two adjacent rear panels 2 are fixedly connected to the shear wall 1 by bolts at their overlapped positions along the wind.
