Double-leaf fireproof door syn-position device with door magnetic system and installation method of double-leaf fireproof door syn-position device

Abstract

The invention provides a double-door fireproof door syn-position device with a door magnetic system and an installation method of the double-door fireproof door syn-position device. The double-door fireproof door syn-position device with the door magnetic system comprises a door magnetic switch and a permanent magnet; the syn-position device comprises two bases, a supporting component and a long-leg sliding rail. The two bases are symmetrically arranged at the two ends of the door magnetic switch and arranged in the middle of the upper door frame. One end of the supporting component is arranged between the two bases, and the free end of the supporting component can slide relative to a long-leg sliding rail arranged on the outer door leaf. The door magnetic switch is embedded in the base of the syn-position device, so that the syn-position device and the door magnetic system can be mounted at the same time under the condition that an existing fireproof door is not damaged and replaced, and the problem that the syn-position device cannot be mounted due to conflict between mounting positions of the syn-position device and the door magnetic system is solved. In addition, compared with a common normally-closed type double-door fire exit door magnet needing to be provided with two door magnet systems (namely, two door magnet switches and a permanent magnet), the field installation time is shortened, and the installation cost is reduced.

Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a double-leaf fire door sequencer with a door magnetic system and an installation method thereof. Background Art

[0002] In order to meet the needs of the final commissioning and daily use and management of the building, it is currently more common to install normally closed fire door magnets on double-leaf and multi-leaf fire doors in some floors, equipment rooms and other areas. Normally closed fire door magnets monitor and record the opening, failure and closing status information of the normally closed fire doors, and feed the information back to the fire door monitoring host (or fire door monitoring extension). Among them, for double-leaf fire doors, the concave and convex matching structure of the closed vertical edges of the two doors is used to achieve the sealing of the door. When using, the inner door leaf close to the door frame must be closed first according to the design requirements, and then the outer door leaf must be closed. Otherwise, the door will not be closed properly and a gap will be left. According to fire protection regulations, many passages and rooms need to be normally closed. In order to control the orderly closing of fire doors after entering and exiting, fire door sequencers are installed to solve this problem.

[0003] However, the door magnetic switch in the normally closed fire door is generally installed in the center of the door frame, which conflicts with the installation position of the fire door sequencer, resulting in the fire door sequencer not being installed. Summary of the invention

[0004] The purpose of the present invention is to provide a double-leaf fire door sequencer with a door magnetic system and an installation method thereof, so as to solve the problem that the fire door sequencer cannot be installed due to the conflict between the installation positions of the fire door sequencer and the door magnetic switch body.

[0005] In order to solve the above technical problems, the present invention provides a double-leaf fire door sequencer with a door magnetic system, and the double-leaf fire door sequencer with a door magnetic system comprises:

[0007] A sequencer comprises: two bases and a supporting component; the two bases are symmetrically arranged at the two ends of the door magnetic switch and are both arranged in the middle of the upper door frame; one end of the supporting component is arranged between the two bases.

[0008] Optionally, in the double-leaf fire door positioner with a door magnetic system, the positioner also includes: a long-leg slide rail, which is arranged on the outer door leaf to provide a movement path for the free end of the supporting component.

[0009] Optionally, in the double-leaf fire door positioner with a door magnetic system, the positioner further includes: a bracket, which is arranged on the inner door leaf to support the supporting component.

[0010] Optionally, in the double-leaf fire door positioner with a door magnetic system, the positioner also includes: a Leroy triangle component, which is arranged between the base and the supporting component on one side adjacent to the inner door leaf, and its longitudinal outer edge is higher than the fixed end of the supporting component and the base.

[0011] Optionally, in the double-leaf fire door positioner with a door magnetic system, the supporting component includes: a bearing sleeve, a long leg and a roller, and both ends of the bearing sleeve are arranged between two bases; one end of the long leg is vertically fixed on the bearing sleeve, and the other end is connected to the roller.

[0012] Optionally, in the double-leaf fire door positioner with a door magnetic system, each base includes: a first component and a second component perpendicular to the first component, and the door magnetic switch is arranged between the first components of the two bases; and the supporting component is arranged between the second components of the two bases.

[0013] Optionally, in the double-leaf fire door positioner with a door magnetic system, each base includes: a first bolt hole opened on the first component and a second bolt hole opened on the second component, and the door magnetic switch and the supporting component are respectively connected to the base by bolts passing through the first bolt hole and the second bolt hole.

[0014] Optionally, in the double-leaf fire door selector with a door magnetic system, the long-leg slide rail is arc-shaped and the selector is a stainless steel selector.

[0015] The present invention also provides a method for installing a double-leaf fire door sequencer with a door magnetic system, the method comprising: S1, first fixing the base of the sequencer in the middle of the upper door frame, and then connecting the door magnetic connection line of the door magnetic switch to the reserved pipeline on the wall;

[0016] S2. Install a permanent magnet on the outer door leaf of the fire door at the position corresponding to the door magnetic switch.

[0017] Optionally, the installation method of the double-leaf fire door sequencer with a door magnetic system further includes:

[0018] S3. Install a bracket on the inner door leaf of the fire door at a position corresponding to the fixed end of the supporting component of the sequencer;

[0019] S4. Install a long-leg slide rail on the outer door leaf of the fire door at the free end of the supporting component of the sequencer.

[0021] On the other hand, by adding a bracket and a Lelo triangle component, contact is established between the supporting component and the base and the bracket based on the Lelo triangle component. Since the edge of the Lelo triangle component is arc-shaped, rolling friction reduces damage to the fire door and reduces noise.

[0022] On the other hand, by installing a long-leg slide rail on the outer door leaf corresponding to the free end position of the supporting component, the collision between the selector and the fire door (door frame and outer door leaf) when the fire door is closed is reduced, thereby reducing noise, extending the service life of the selector, and reducing damage to the fire door leaf and door frame.

[0023] On the other hand, the selector is made of stainless steel, which has a stable structure, high yield resistance, is not easy to be damaged, and has a beautiful appearance. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The following is a further detailed description of the double-leaf fire door sequencer with door magnetic system and its installation method proposed by the present invention in combination with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer according to the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0046] In the description of the invention, it is necessary to understand that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “clockwise”, “counterclockwise”, etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the invention.

[0047] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0048] In the invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to the specific circumstances.

[0049] Please refer to Figure 1 and Figure 8 The double-leaf fire door sequencer with a door magnetic system includes: a door magnetic system and a sequencer, the door magnetic system includes: a door magnetic switch 41 and a permanent magnet 43, the permanent magnet 43 is arranged on the outer door leaf 2; the sequencer includes: two bases 11 and a supporting component; the two bases 11 are symmetrically arranged at both ends of the door magnetic switch 41, and are both arranged in the middle of the upper door frame; one end of the supporting component is arranged between the two bases 11.

[0050] like Figure 1 As shown, by embedding the door magnetic switch 41 in the two bases 11 of the sequencer, the sequencer and the door magnetic system can be installed at the same time without destroying or replacing the existing fire door, avoiding the problem that the sequencer cannot be installed due to the conflict between the installation positions of the two. In addition, compared with the general normally closed double-door fire door magnetic, two sets of door magnetic systems (i.e., two door magnetic switches 41 and permanent magnets 43) need to be installed, which reduces the on-site installation time and installation cost.

[0051] For further information, please refer to Figure 1 , Figure 6 , Figure 7 , Figures 11 to 14 , the sequencer also includes: a long-leg slide rail 32 and a bracket 31. The long-leg slide rail 32 is arranged on the outer door leaf 2 to provide a movement path for the free end of the supporting component; the bracket 31 is arranged on the inner door leaf to support the supporting component and reduce the damage caused by the direct contact between the supporting component and the inner door leaf. By installing the long-leg slide rail 32 on the outer door leaf corresponding to the free end position of the supporting component, the collision between the sequencer and the fire door (door frame 3 and outer door leaf 2) when the fire door is closed is reduced, thereby reducing noise, extending the service life of the sequencer, and reducing damage to the door leaf and door frame of the fire door. Preferably, as Figure 7 As shown, the long-leg slide rail 32 is arc-shaped.

[0052] The shunter is a stainless steel shunter, which is made of stainless steel and has a stable structure, high yield resistance, is not easy to be damaged, and has a beautiful appearance.

[0053] For better, please refer to Figure 1 , Figure 4 , Fig.13 and Fig.14 The sequencer also includes: a Leroy triangular component 12, which is arranged between the base and the supporting component on one side of the inner door leaf, and its longitudinal outer edge is higher than the fixed end of the supporting component and the base. Based on the additional bracket and the Leroy triangular component 12, the supporting component and the base are in contact with the bracket based on the Leroy triangular component 12. Since the edge of the Leroy triangular component 12 is arc-shaped, rolling friction reduces damage to the fire door and reduces noise.

[0054] Please refer to Figure 5 The supporting component includes: a bearing sleeve 20, a long leg 21 and a roller 22. The two ends of the bearing sleeve 20 are arranged between the two bases 11; one end of the long leg 21 is vertically fixed on the bearing sleeve 20, and the other end is connected to the roller.

[0055] Please refer to Figure 2 and Fig. 9Each base includes: a first component and a second component perpendicular to the first component, the door magnetic switch 41 is arranged between the first components of the two bases; the supporting component is arranged between the second components of the two bases; wherein each base includes: a first bolt hole opened on the first component and a second bolt hole opened on the second component, the door magnetic switch 41 and the supporting component are respectively connected to the base by bolts penetrating the first bolt hole and the second bolt hole.

[0056] Accordingly, this embodiment also provides a method for installing a double-leaf fire door sequencer with a door magnetic system. Figures 1 to 15 The installation method of the double-leaf fire door sequencer with door magnetic system described in this embodiment is described in detail.

[0057] First, execute step S1, first fix the base of the sequencer in the middle of the upper door frame 3, and then connect the door magnetic connection line 42 of the door magnetic switch 41 to the reserved wall pipeline 4;

[0058] Next, step S2 is performed to install a permanent magnet 43 at a position corresponding to the door magnetic switch 41 on the outer door leaf 2 of the fire door;

[0059] Next, step S3 is performed to install a bracket 31 on the inner door leaf 1 of the fire door at a position corresponding to the fixed end of the supporting component of the sequencer;

[0060] Next, step S4 is executed to install the long-leg slide rail 32 at the free end position of the supporting component of the sequencer on the outer door leaf 2 of the fire door.

[0061] Please combine Figure 1 , Figures 13 to 15 The working principle of the double-leaf fire door sequencer with door magnetic system of the present invention is as follows:

[0062] The base of the sequencer is divided into two (i.e., the original one base design is divided into two bases), firstly, the door magnetic switch 41 is fixed to the bases 11 on both sides by screws, and then the door magnetic switch 41 is installed in the middle of the upper door frame 3, and the long leg 21 naturally droops due to gravity. When the two doors are closed and run to the sequencer, the long leg 21 supports the outer door leaf 2, and the bracket 31 is installed at the corresponding position of the inner door leaf 1. When the inner door leaf 1 continues to run and the long leg 21 is supported by the bracket 31 (corresponding to Fig.14 The middle bracket 31 supports the Leroy triangle component and indirectly supports the long leg 21), and the outer door leaf 2 is closed to achieve the effect of orderly closing of the two door leaves. Limited by the working principle of the sequencer, the inner door leaf 1 is a prerequisite for the outer door leaf 2 to be closed, so the door magnetic system mainly monitors the switch state of the outer door leaf 2. When the outer door leaf 2 is closed, the distance between the door magnetic switch 41 and the permanent magnet 43 is within a certain range, and the door magnetic system will send a fire door closing signal and feed back the fire door closing signal to the fire alarm monitoring system.

[0063] It should be noted that, for the aforementioned method embodiments, for the sake of simplicity, they are all expressed as a series of action combinations, but those skilled in the art should be aware that the present application is not limited by the described order of actions, because according to the present application, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the present application.

[0064] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0065] The present invention has the following advantages:

[0066] 1) By embedding the door magnetic switch in the base of the sequencer, the sequencer and the door magnetic system can be installed at the same time without destroying or replacing the existing fire door, avoiding the problem of the sequencer being unable to be installed due to conflicts in the installation positions of the two. In addition, compared with the general normally closed double-door fire door magnetic, two sets of door magnetic systems (i.e. two door magnetic switches and permanent magnets) need to be installed, which reduces the on-site installation time and installation costs.

[0067] 2) Based on the addition of a bracket and a Lelo triangle component, the support component and the base are in contact with the bracket based on the Lelo triangle component. Since the edge of the Lelo triangle component is arc-shaped, rolling friction reduces damage to the fire door and reduces noise.

[0068] 3) By installing a long-leg slide rail on the outer door leaf corresponding to the free end position of the supporting component, the collision between the selector and the fire door (door frame and outer door leaf) when the fire door is closed is reduced, thereby reducing noise, extending the service life of the selector, and reducing damage to the fire door leaf and door frame.

[0069] 4) The positioner is made of stainless steel, with stable structure, high yield resistance, not easy to damage and beautiful appearance.

[0070] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
