Description

Technical Field

[0001] This invention relates to the field of fire protection, and more particularly to a fire-resistant partition system. Background Technology

[0002] my country has strict fire protection requirements for buildings. Buildings are usually divided into different fire protection zones, and fire isolation measures must be set up between each fire protection zone. In the event of a fire, the fire isolation measures must be able to completely isolate each fire protection zone to prevent the fire from spreading across zones. At the same time, the drainage system and ventilation system must be isolated at the isolation points of each fire protection zone.

[0003] To meet the fire isolation requirements of drainage and ventilation systems at the partitions between fire compartments, independent drainage and ventilation systems are typically installed in each fire compartment. Each fire compartment is equipped with a sump and a drainage pump, all connected to the outdoor drainage system via pressure pipes. Similarly, independent ventilation systems are usually installed in each fire compartment, requiring a large number of electrically controlled isolation valves, or each fire compartment may have its own independently installed electrically controlled isolation valves. However, this method suffers from drawbacks: a large number of drainage and ventilation systems are present, their distribution is dispersed, drainage and ventilation outlets are difficult to locate, and control and maintenance are extremely labor-intensive. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the existing technology in which the ventilation system and drainage system of the building are numerous and difficult to arrange, control and maintain, and to provide a fire-fighting partition system and an integrated pipe gallery including the same.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A fire-resistant partition system comprising:

[0007] Fire doors;

[0008] A drainage system and a drainage baffle, wherein the drainage system includes a drainage ditch, the drainage baffle cooperates with the drainage ditch, and the drainage baffle is set corresponding to the fire door, the drainage baffle does not block the drainage ditch when the fire door is opened, and can block the drainage ditch when the fire door is closed;

[0009] A ventilation baffle and a ventilation system are provided. The ventilation system includes a ventilation hole located above the drainage ditch. Both the ventilation baffle and the ventilation hole are provided corresponding to the fire door. The ventilation baffle cooperates with the ventilation hole. The ventilation baffle does not cover the ventilation hole when the fire door is opened and can cover the ventilation hole when the fire door is closed.

[0010] In this technical solution, a ventilation damper is installed to cooperate with the ventilation opening. In the event of a fire or other emergency, the fire door is closed, and the ventilation damper closes the ventilation opening at the same time. Normally, the fire door is open, and the ventilation damper does not close the ventilation opening, which does not affect the normal operation of the ventilation system.

[0011] Drainage baffles are installed to open or close the drainage ditch. In the event of a fire or other emergency, the fire doors are closed, and the drainage baffles isolate the drainage ditch to cut off the drainage system. Under normal circumstances, the fire doors are open, the drainage baffles do not isolate the drainage ditch, and the drainage system operates normally.

[0012] Ventilation openings are located above drainage ditches to prevent water overflow from affecting ventilation at the openings and to improve the reliability of the fire-fighting partition system.

[0013] Preferably, the ventilation system includes a ventilator that is compatible with the ventilation opening.

[0014] In this technical solution, the ventilator is matched with the ventilation hole, and the number and position are adapted to the ventilation hole. When the ventilation hole is unobstructed, the ventilator ventilates from the ventilation hole.

[0015] Preferably, the ventilation baffle can move up and down or left and right relative to the ventilation hole; or the ventilation baffle is fixed to the fire door.

[0016] In this technical solution, the ventilation damper is fixed to the fire door and can move with the fire door, opening or closing the ventilation hole synchronously with the opening or closing of the fire door. The structure is simple and reliable.

[0017] The ventilation damper can move up and down or left and right relative to the fire door. It can be installed on the fire door or around the ventilation opening, offering flexible placement. When the fire door is open, the ventilation damper must not cover the ventilation opening to ensure the normal operation of the ventilation system. When the fire door is closed, the ventilation damper moves relative to the ventilation opening to completely cover it, thus isolating the ventilation system. The ventilation damper can be installed on the fire door or around the ventilation opening.

[0018] Preferably, the ventilation baffle is a synchronously moving structure or a foldable and retractable structure.

[0019] In this technical solution, the ventilation damper is configured as a structure that moves synchronously with the fire door or is foldable and retractable. When the fire door is closed, the ventilation damper moves synchronously or unfolds to a position that covers the ventilation opening. The foldable and retractable ventilation damper structure is in a folded state when the fire door is open, thus occupying less space.

[0020] Preferably, the fire-fighting partition system further includes a drainage system, the drainage system including a drainage ditch, characterized in that the fire-fighting partition system further includes a drainage baffle that cooperates with the drainage ditch, the drainage baffle not blocking the drainage ditch when the fire door is opened, and blocking the drainage ditch after the fire door is closed.

[0021] Preferably, the fire door is a revolving door, the drainage ditch includes at least one drainage arc segment coaxial with the fire door, the drainage baffle is disposed at the bottom of the fire door and located within the drainage arc segment, the width of the drainage baffle is smaller than the cross-sectional dimension of the drainage ditch, and the cross-sectional dimension of the drainage baffle parallel to the plane of the fire door matches the cross-sectional dimension of the drainage ditch.

[0022] In this technical solution, the fire door is a revolving door, and a drainage baffle is installed at the bottom of the fire door. During the opening or closing of the fire door, the drainage baffle rotates along with the fire door. The drainage ditch includes a drainage arc section coaxial with the fire door, and the drainage baffle is located within the drainage ditch. During the rotation of the fire door, the drainage baffle rotates within the drainage arc section of the drainage ditch. The fire door plane refers to the width × height plane of the fire door. The cross-sectional dimensions of the drainage baffle, parallel to the fire door plane, match the cross-sectional dimensions of the drainage ditch. When the fire door is closed, the drainage baffle completely blocks the drainage ditch. The width of the drainage baffle refers to the dimension along the thickness direction of the fire door. The width of the drainage baffle is smaller than the cross-sectional dimension of the drainage ditch, ensuring that the drainage baffle does not completely block the drainage ditch when the fire door is open, thus guaranteeing the normal operation of the drainage system.

[0023] Preferably, the drainage arc segment includes a first drainage arc segment located in the opening direction of the fire door, and the central angle corresponding to the first drainage arc segment is at least 90°.

[0024] In this technical solution, the first drainage arc segment is located in the opening direction of the fire door and is at least 90°, ensuring that the drainage baffle can rotate at least 90° within the drainage ditch, that is, ensuring that the fire door can be opened at least 90°.

[0025] Preferably, the fire-resistant partition system further includes a drainage ditch cover plate covering the drainage arc section, the drainage ditch cover plate being fixed to the bottom of the fire door and located above the drainage ditch.

[0026] In this technical solution, a drainage ditch cover is installed above the drainage arc section to cover the drainage ditch and prevent people from stepping into it. The drainage ditch cover is adapted to the drainage ditch, and can cover the drainage arc section within the rotation range of the fire door.

[0027] Preferably, the fire-resistant partition system further includes a door closer for opening and / or closing the fire door, the door closer being connected to the fire door.

[0028] In this technical solution, a door closer is installed, which can automatically close the fire door in the event of an emergency;

[0029] And / or after the emergency has ended, the door closer can open the fire door.

[0030] Preferably, the number of fire doors is at least two, and the two fire doors are connected to each other. Each fire door is provided with at least one ventilation baffle, one ventilation hole, one drainage baffle, and one door closer.

[0031] In this technical solution, in the event of an emergency, the door closer can automatically close the fire door and isolate each fire compartment, including isolating the ventilation and drainage of each fire compartment;

[0032] And / or after the emergency has ended, the door closer can open the fire doors, connecting the various fire compartments, including connecting the ventilation and drainage of each fire compartment. Preferably, the number of fire doors is at least two, and the area between the two fire doors is connected. Each fire door is provided with at least one ventilation baffle, one ventilation hole, one drainage baffle, and one door closer; when the fire doors are open, the ventilation holes are connected, and the drainage ditches are also connected.

[0033] In this technical solution, the fire-resistant partition system includes at least two fire doors. When the fire doors are open, all ventilation openings and drainage ditches are connected, including at each fire door. Areas corresponding to multiple fire doors can share the ventilation system and drainage system, reducing the number of ventilation and drainage systems.

[0034] An integrated utility tunnel, comprising the fire-resistant partition system described in any of the foregoing technical solutions.

[0035] The positive and progressive effects of this invention are as follows:

[0036] By installing ventilation baffles and drainage baffles, ventilation baffles close ventilation holes and drainage baffles block drainage ditches in the event of fire or other emergencies, thus achieving fire-resistant partitioning. Applying this fire-resistant partitioning system to integrated utility tunnels allows multiple fire compartments to share ventilation and drainage systems, reducing the number of ventilation and drainage systems required and simplifying the layout of the fire-resistant partitioning system.

[0052] Floor 2. Detailed Implementation

[0053] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0054] Figures 1-9 This is a schematic diagram of the structure of a fire-fighting partition system 1 provided in an embodiment of the present invention.

[0055] like Figure 5 As shown, the fire-resistant partition system 1 includes a fire door 10 ( Figure 5 Unmarked, see Figure 1 ), ventilation system (not marked in the figure), ventilation baffle 42, drainage system 30 ( Figure 5 Unmarked, see Figure 3 ), Drainage baffle 32.

[0056] The ventilation system includes ventilation holes 41 and a ventilator 43; the drainage system 30 includes a drainage ditch 31 and a drainage ditch cover 33; the fire door 10 is located above the ground level 2 and includes a door frame 11, a door leaf 12, a door lock 14, a handle 15, and fire-resistant glass 16. The door leaf 12 and the door frame 11 are connected by a hinge 13, and the door leaf 12 can rotate around the hinge 13. The fire-resistant glass 16 is transparent to allow observation of the fire compartments on both sides of the fire door 10.

[0057] A ventilation baffle 42 is fixed to the door leaf 12. The shape, position, and size of the ventilation baffle 42 are adapted to the ventilation opening 41, ensuring that when the fire door 10 is closed, the ventilation baffle 42 can completely cover or block the ventilation opening 41, thus completely isolating the ventilation system. The ventilation opening 41 is located above the door frame 11 of the fire door 10, and the corresponding ventilation baffle 42 is also located above the door leaf 12 of the fire door 10, so that when the fire door 10 is open, the ventilation baffle 42 does not obstruct entry and exit from the fire door 10. The ventilation opening 41 is located above the drainage ditch 31 to prevent water overflow from the drainage ditch 31 from affecting the ventilation of the ventilation system.

[0058] like Figure 8 As shown, the drainage ditch 31 is located below the fire door 10 and also below the floor 2. The drainage baffle 32 is fixed to the bottom of the door leaf 12 and located within the drainage ditch 31. The drainage ditch cover 33 is located above the drainage ditch 31 and fixed to the bottom of the door leaf 12. The dimensions of the drainage baffle 32 in the plane of the door leaf 12 are adapted to the cross-sectional dimensions of the drainage ditch 31. When the door leaf 12 is closed, the drainage baffle 32 can isolate the drainage ditch 31. Figure 4 As shown, the width of the drainage baffle 32 (in the width direction of the door leaf 12) is smaller than the cross-sectional dimension of the drainage ditch 31. When the fire door 10 is fully open, the drainage baffle 32 cannot block the drainage ditch 31, and the drainage system 30 operates normally. Figure 9 As shown, the drainage ditch 31 includes a drainage arc section 310. During the rotation of the fire door 10, the drainage baffle 32 moves with the door leaf 12 and moves within the first arc section 311 of the drainage ditch 31. The first arc section 311 is 90°, ensuring that the drainage baffle 32 can rotate 90°, that is, the door leaf 12 of the fire door 10 can rotate 90°.

[0059] like Figure 3As shown, the drainage ditch cover 33 is arc-shaped, and its shape and size are adapted to the drainage arc section 310 of the drainage ditch 31. The drainage ditch cover 33 has a radius of 270°. Figure 9 As shown, the drainage arc segment 310 of the drainage ditch 31 is 180°, of which the first drainage arc segment 310 is 90°. The central angle of the drainage ditch cover 33 is larger than the central angle of the drainage arc segment 310, as shown. Figure 4 , Figure 5 , Figure 6 As shown, when the fire door 10 is closed, partially open, or fully open, the drainage ditch cover 33 can cover the drainage arc section 310 of the drainage ditch 31 to prevent accidental stepping into the drainage ditch 31.

[0060] In other embodiments, the ventilation baffle 42 can be configured to move synchronously, fold, or otherwise move relative to the ventilation opening 41. When the fire door 10 is open, the ventilation baffle 42 does not cover the ventilation opening 41; after the fire door 10 is closed, the ventilation baffle 42 moves or unfolds to cover the ventilation opening 41, thus blocking the ventilation system. In other embodiments, the drainage baffle 32 can also be configured to move or fold relative to the drainage ditch 31.

[0061] In other embodiments, the fire door 10 can be configured as a revolving door, a sliding door, or other forms to achieve opening and closing.

[0062] like Figure 5 As shown, the fire-fighting partition system 1 also includes a door closer 20, with one end connected to the door frame 11 and the other end connected to the door leaf 12. In this embodiment, the fire-fighting partition system has multiple fire doors 10, each fire door 10 having two ventilation openings 41, two ventilation baffles 42, one drainage baffle 32, and one door closer 20. Adjacent fire doors 10 are interconnected. The area between two fire doors constitutes a fire compartment, and the ventilation openings 41 connect to each fire compartment, as do the drainage ditches 31.

[0063] like Figure 4 As shown, normally the door leaf 12 is fully open outside the door frame 11, the ventilation baffle 42 cannot cover or block the ventilation hole 41, the ventilation system works normally, the ventilation fan 43 is used to ventilate from the ventilation hole 41 at the top of the door frame 11, and the open door frame 11 can also ensure ventilation, the ventilation of each fire compartment is connected; the drainage baffle 32 cannot block the drainage ditch 31, the drainage ditches of each fire compartment are connected, the drainage system 30 works normally.

[0064] like Figure 6As shown, in the event of a fire hazard or emergency, each door closer 20 can automatically close its corresponding door leaf 12, and the closed door leaf 12, together with the door frame 11, forms a fire-resistant partition; the ventilation baffle 42 will completely cover the ventilation opening 41. Figure 6 The ventilation vents 41 are not marked, and the ventilation systems of each fire compartment are also isolated; the drainage baffles 32 isolate the drainage ditches 31, and the drainage systems 30 of each fire compartment are also isolated.

[0065] After the firefighting operation is completed and confirmed by staff, the doors 12 of each fire door 10 are manually reopened, and the ventilation and drainage systems 30 of each fire compartment are simultaneously restored to normal operation. In other embodiments, after the firefighting operation is completed and confirmed by manual inspection, the doors 12 of the fire doors 10 can also be automatically opened directly by the door closer 20. In this embodiment, multiple fire compartments can share the ventilation and drainage systems, reducing the number of ventilation and drainage systems and simplifying the layout of the fire partition system.

[0066] In other embodiments, the door closer 20 may not be provided, and the fire door 10 may be opened or closed manually.

[0067] In this embodiment, both the ventilation baffle 42 and the drainage baffle 32 are fixed to the door leaf 12 of the fire door 10 and move together with the door leaf 12, which can realize the simultaneous isolation or connection of ventilation and drainage in each fire compartment, thereby improving the reliability of the fire isolation system.

[0068] In this embodiment, the fire-fighting partition system includes a control module. The control module is electrically connected to sensors installed within the integrated utility tunnel and determines the hazard based on sensor signals, thereby controlling the action of the door closer. Simultaneously, when the control module controls the door closer to close the fire door, it also controls the ventilation fan to stop ventilation.

[0069] By applying the fire-resistant partition system from any of the foregoing embodiments to a utility tunnel, a utility tunnel with fire-resistant partition function can be obtained. For details on how to apply the fire-resistant partition system to a utility tunnel, please refer to the prior art.
