Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fire safety, and in particular relates to a self-linking fireproof partition ventilation structure. Background Art
[0002] Fire safety involves personal safety. According to Article 6.1.1 of the General Code for Fire Protection of Buildings GB55037-2022, Article 5.2.5 and Article 5.2.6 of the Design Code for Fire Protection of Garages, Repair Garages and Parking Lots GB50067-2014, the test method of the Test Method for Fire Resistance of Ventilation Ducts GB / T17428, and Article 3.1 and Article 5.1 of the Fire Dampers for Building Ventilation and Smoke Exhaust Systems, there are certain requirements for the installation of fire dampers. Fire dampers mainly play the role of smoke and fire prevention in pipes. Due to the properties of common materials such as cold-rolled steel plates, galvanized steel plates, and stainless steel plates on the market, they cannot meet the requirements of "thermal insulation" in fire resistance tests. In addition, the requirements for fire resistance time and fire resistance integrity of fireproof partitions and fire walls are clearly defined. As a result, fire dampers based on fire dampers do have the hidden danger of not meeting the requirements of the regulations. As a result, fire inspection and acceptance in some areas (such as Xiamen, Fujian) clearly pointed out that fire dampers cannot meet the fire resistance limit requirements of corresponding fire partition walls / firewalls, and fire vents are not allowed to be directly installed on fire partition walls / firewalls. Fire-resistant air ducts must be installed within 2m before and after the fire dampers. However, in actual applications, for most equipment room side walls with exhaust vents, side wall fire air supply vents, and charging pile unit indirect air supply vents, according to the fire inspection and acceptance requirements, 2 meters of pipes are installed before and after the fire vents for fireproofing. This causes insufficient height of the on-site pipelines, affects the passage outside the machine room, reduces the overall appearance of underground garages and other buildings, and wastes materials and labor.

[0028] Reference Figure 1-6 As shown, a self-linked fireproof partition ventilation structure includes an air supply port 1, a slide 2, a fireproof heat insulation board 3 and a pin traction assembly 4, wherein the slide 2 is vertically arranged on the outside of the air supply port 1, and the slide 2 is arranged on both sides of the air supply port 1. The length of the slide 2 is not less than twice the height of the air supply port 1, and the slide 2 extends above the air supply port 1; the fireproof heat insulation board 3 is arranged in the slide 2, and the size of the fireproof heat insulation board 3 is greater than or equal to the size of the air supply port 1; the pin traction assembly 4 is arranged on the upper end face of the air supply port 1, one end of the pin traction assembly 4 is abutted, and the other end is linked with the screw head 5 of the fire damper handle.
[0029] The present application provides a device that can be linked and closed by setting a fireproof heat insulation board 3 at the air supply port 1 in the event of a fire, thereby avoiding the need to set a 2-meter pipeline before and after the fireproof air port for fireproof wrapping, resulting in insufficient height of the on-site pipeline, affecting the passage outside the machine room, resulting in a decline in the overall appearance of buildings such as underground garages, and waste of materials and labor. The fireproof heat insulation board 3 closes or opens the air supply port 1 by sliding up and down on the slide 2, and the opening and closing of the fireproof heat insulation board 3 is achieved by the bayonet traction assembly 4. In the normal state, the bayonet traction assembly 4 is locked and fixed above the air supply port 1; when a fire occurs, the screw head 5 of the fire damper handle rotates to drive the bayonet traction assembly 4 to be pulled out from the lower end of the fireproof heat insulation board 3, and the fireproof heat insulation board 3 descends along the slide 2 to close the air supply port 1.
[0030] When the screw head 5 of the fire damper handle is closed, a stroke of 1 / 4 of the circumference, about 21 mm, can be generated, which is sufficient to open the latch 42.
[0031] The fireproof time of fireproof insulation board 3 is 2H / 3H, depending on the specific use site requirements. The specific materials of fireproof insulation board 3 can be referred to: steel fireproof insulation finished composite board, the base material is non-combustible A2 grade inorganic microporous magnesium crystalline silicon board (density ≤350KG / m3, does not contain polystyrene and wood chips and other combustibles), the fire resistance limit should comply with the relevant requirements of the "Technical Standard for Building Smoke and Exhaust System" (GB51251-2017); when the fire resistance limit is ≤1.0 hour, the total thickness of the composite board is ≥10mm, when the fire resistance limit is ≤2.0 hours and >1 hour, the total thickness of the composite board is ≥15mm, when the fire resistance limit is ≤3.0 hours and >2 hours, the total thickness of the composite board is ≥40mm, and the inner and outer surfaces are covered with 0.2mm color steel plate.
[0032] Furthermore, the bayonet traction assembly 4 is provided with a slide rail 41, a bayonet 42, a spring 43 and a steel wire rope 44. The slide rail 41 is fixed to the upper end surface of the air supply port 1, the bayonet 42 is slidably arranged at the front end of the slide rail 41, and the overhead line extends out of the air supply port 1 to abut against the lower side edge of the fireproof insulation board 3. A baffle 45 is provided at the end of the slide rail 41, and the spring 43 is arranged between the bayonet 42 and the baffle 45. One end of the steel wire rope 44 passes through the baffle 45 and is connected to the bayonet 42, and the other end is connected to the screw head 5 of the fire damper handle.
[0033] In the normal state, the front end of the latch 42 is pushed out of the slide rail 41 under the action of the spring 43, and abuts against the lower end of the fireproof insulation board 3, fixing the fireproof insulation board 3 above the air supply port 1; when a fire occurs, the screw head 5 of the fire damper handle rotates, driving the wire rope 44, and the wire rope 44 overcomes the force of the spring 43 to pull the latch 42 backward, so that the latch 42 is separated from the fireproof insulation board 3, and the fireproof insulation board 3 falls on the slide 2 under the action of gravity, closing the air supply port 1.
[0034] Furthermore, a transmission wheel 46 is provided at the corner between the bayonet 42 and the line connecting the steel wire 44 of the screw head 5 of the fire damper handle.
[0035] The transmission wheel 46 allows the steel wire rope 44 to have better sliding force, thereby preventing excessive friction, or the steel wire rope 44 from being worn or damaging other components due to long-term pulling.
[0036] Furthermore, at least one pulley (not shown) is provided on the wire rope 44 between the transmission wheel 46 and the screw head 5 of the fire damper handle, and the pulley is arranged on the vertical lines on both sides between the transmission wheel 46 and the screw head 5 of the fire damper handle.
[0037] By setting a pulley, the pulling force of the screw head 5 of the fire damper handle on the steel wire 44 can be reduced to avoid damaging the fire damper; thereby, the elastic force of the spring 43 can be increased to ensure the force of the latch 42 on the fireproof insulation board 3. In order to match the torque of the screw head 5 of the fire damper handle, multiple pulleys can be set to form a pulley group to reduce the pulling force.
[0038] Furthermore, a roller or a ball (not shown) is provided between the slide 2 and the fireproof heat insulation board 3 , and the roller or the ball is installed on the slide 2 or the fireproof heat insulation board 3 .
[0039] The smoothness of the falling of the fireproof and heat-insulating board 3 is improved by adding rollers or balls to avoid jamming.
[0040] Furthermore, the latch 42 is a wedge-shaped block.
[0041] The wedge-shaped block facilitates the removal of the latch 42 from the fireproof insulation board 3 .
[0042] Furthermore, the fireproof heat insulation board 3 is provided with a vertical slide plate at a position corresponding to the latch 42 .
[0043] This prevents the locking pin 42 from being pushed out and causing damage to the fireproof and heat-insulating board 3 , or even causing the fireproof and heat-insulating board 3 to get stuck.
[0044] Furthermore, the steel wire rope 44 is welded or fixedly connected to the screw head 5 of the fire damper handle by a clamp.
[0045] Furthermore, a wind blade 11 is provided at the front end of the air supply port 1.
[0046] The wind blade plate 11 prevents debris or mice from entering the air supply port 1. The wind blade plate 11 can be arranged on the inner side of the fireproof and heat-insulating board 3, or on the outer side.
[0047] Furthermore, a limiting plate 21 is provided at the lower end of the slideway 2 .
[0048] The height to which the fireproof and heat-insulating board 3 descends is limited.
[0049] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
