Description

The structure with 270° opening fireproof smoke shielding door

The present invention provides a structure with 270-degree opening fire-proof smoke-shielding door which can effectively shield the gaps between various structures, so that the fire-proof door has both 270-degree rotation and good smoke-shielding effect.

Most of the urbanites live in high-rise buildings. When a fire occurs in a high-rise building, due to the crowded environment and the design of the building structure, the chimney effect is likely to occur. Therefore, in addition to fire fighting and sprinkler equipment, fire doors will also be installed on each floor. . Fire doors are generally set at the passageway on the side of the elevator or escape ladder. In order to facilitate the daily passage of residents, the current method of opening them normally and closing them in case of fire is often used. Requirements and other factors, it must have the performance of fire prevention and smoke shielding, so it is often equipped with fire doors that open at 270 degrees.

However, in order to make the fire door rotate 270 degrees, the general practice is to design the shape of the adjacent sides of the door body and the frame body as a 1/4 arc or a beveled angle, which greatly increases the difficulty in the process and the corresponding cost. It can only increase the distance between the door and the frame, but it will reduce the ability of the fire door to block fire and smoke. If the metal sheet is used to connect the door and the frame, in order to expand the distance, try to use each other. The close-fitting metal sheet blocks the thick smoke, but the thick smoke is pervasive under high temperature and high pressure, and the metal sheet cannot reliably isolate the thick smoke, and the sheet metal can set the position of the rubber strip is limited, and it is difficult to fill this loophole. Furthermore, There is a risk of deformation of the metal sheet after reaching a certain high temperature, and it may also cause the door to be unable to open and close again.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the creators of this new model and related manufacturers in this industry are eager to research and improve.

Therefore, in view of the above-mentioned deficiencies, the creator of this new model has collected relevant information, evaluated and considered from various parties, and based on years of experience accumulated in this industry, through continuous trials and revisions, before designing this kind of structure that can effectively cover various structures. The gap between the fire doors has a 270-degree rotation and a good smoke-shielding effect. The new patented structure of the fire-proof smoke-shielding door with 270-degree opening.

The main purpose of the new model is: the second fireproof frame is designed with an adjoining surface, a front surface and a butting surface for setting a plurality of smoke shielding seals, so that the fire door can not only be opened 270 degrees, but also have good smoke shielding. effect and fire protection.

In order to achieve the above purpose, the main structure of the new model includes: at least one first fireproof frame, at least one first shaft member, a second fireproof frame, an abutting surface, a front surface, a butting surface, and a plurality of second shaft centers parts, at least one first sealing part, at least one second sealing part, and a movable sealing part. Wherein, the first shaft member is arranged on the first fireproof frame, the second fireproof frame is pivoted on the first shaft member to rotate between the closed position and the first open position, and the abutting surface is connected to the first fireproof frame. The frames are arranged adjacently, the front surface is arranged on one side of the adjoining surface, the butting surface is arranged on one side of the front surface, and the second axis piece is arranged on the butting surface and is used for pivoting a fire door, so that the fire door can be closed when it is closed. Rotating between the position and the second open position, the first seal is arranged between the first fireproof frame and the adjoining surface, the second seal is arranged between the front surface and the fire door, and the movable seal is arranged on the fire door bottom.

The new type utilizes the ground hinge to rotate the first axis piece, so that the second fireproof frame takes the first axis piece as the axis to drive the fire door to rotate between the first open position and the closed position, and push the door manually. , so that the fire door can be rotated between the closed position and the second open position with the second axis piece as the axis, so as to achieve the purpose of being able to open 270 degrees. And because the second fireproof frame has an adjoining surface, a front surface and a butting surface, it is slightly rectangular as a whole, so that the first sealing member and the second sealing member can be placed in proper positions to prevent smoke from passing through the first fireproof frame. The gap with the second fireproof frame, or the gap between the second fireproof frame and the fireproof door, and cooperate with the movable seal at the bottom of the fireproof door, so that when the fireproof door is in the closed position, it has the advantage of multi-faceted smoke shielding and achieves effective barrier. The purpose of smoke and fire safety.

With the above technology, the conventional 270-degree open fire door can be met with the requirement of rotating action, which leads to difficult manufacturing process and high cost. The distance between the door and the frame is too large to prevent smoke, and the metal sheet is not conducive to the installation of adhesive strips, etc. The problem points are broken through to achieve the practical progress of the above advantages.

The abutting surface 33 on one side, the second fireproof frame 3 in this embodiment is an example of an L-shaped column with an approximately rectangular cross-section;

A plurality of second shaft elements 4 are arranged on the abutting surface 33 and are used for pivotally connecting a fire door 5, so that the fire door 5 can be rotated between the closed position and a second open position. Door 5 series takes a single door as an example;

at least one first sealing member 61 is disposed between the first fireproof frame 1 and the abutting surface 31;

at least one second sealing member 62 is disposed between the front surface 32 and the fire door 5; and

A movable seal 63 is arranged at the bottom of the fire door 5 to cover the gap between the fire door 5 and the ground;

The inner aggregates of the first fireproof frame 1 , the second fireproof frame 3 and the fireproof door 5 are fireproof and heat-insulating materials, such as calcium silicate board, and the first sealing member 61 , the second sealing member 62 and the movable sealing member 63 It is a fireproof rubber strip, and its material can include polyvinyl chloride (Polyvinyl Chloride, PVC), rubber and graphite.

From the above description, the structure of the present technology can be understood, and according to the corresponding cooperation of the structure, the gap between the structures can be effectively shielded, so that the fire door 5 has the advantages of 270-degree rotation and good smoke shielding effect. A detailed explanation will be given below.

Please also refer to the first to the eighth figures, which are the three-dimensional view to the door opening schematic diagram of the preferred embodiment of the new model. The fire door 5 of this embodiment is set at the passage of the escape ladder, and can be normally opened at the first opening position under normal circumstances, and the opening position is almost parallel to the wall W, so it does not affect the normal walking of the user, and can also Keep the passageway unobstructed. When a fire occurs, the fire door 5 can be closed. At this time, the hinge 21 (which can be a manual hinge 21 or an electric hinge 21) is used to rotate the first shaft member 2, so that the second fireproof frame 3 is moved to the first The axis member 2 is the axis, and the fire door 5 rotates 180 degrees from the first open position and stops at the closed position.

As shown in Figure 6, Figure 6A and Figure 7, when the fire door 5 is in the closed position, the second fire frame 3 is pressed against the first fire frame 1, so that the The first sealing member 61 is pressed by the adjoining surface 31 of the second fireproof frame 3 to prevent smoke from escaping from the gap between the first fireproof frame 1 and the second fireproof frame 3, and since the fire door 5 is connected to the second fireproof frame 3 simultaneous turns to make the setting The second sealing member 62 on the second fireproof frame 3 is maintained in a tightly combined state with the fireproof door 5, so as to prevent smoke from escaping from the gap between the second fireproof frame 3 and the fireproof door 5 (in Fig. The arrows indicate smoke), at the same time, the movable seal 63 located at the bottom of the fire door 5 also shrinks inwardly due to the impact of the telescopic top rod 631, and squeezes the elastic element 632 (in this embodiment, the shrapnel is used as an example) to make it happen After deformation, the sealing strip 633 is extruded downward, so as to prevent smoke from escaping from the gap between the fire door 5 and the ground G by the sealing strip 633 . In this way, when the fire door 5 is in the closed position, the first sealing member 61 , the second sealing member 62 and the movable sealing member 63 can be used to provide the advantage of multi-faceted smoke shielding, so as to effectively block the smoke and improve the fire safety.

As shown in Figure 8, the fire door 5 should be kept in the closed position as much as possible during the fire to prevent the spread of smoke and fire, but in order to ensure that the escape personnel can still pass through, the escape personnel can directly push the fire door 5 to make the fire door 5. Taking the second shaft member 4 as the shaft center, it rotates 90 degrees from the closed position and stops at the second open position.

From this, it can be seen that the fire door 5 of the present invention has the characteristic of opening at 270 degrees, and on this basis, the adjoining surface 31 , the front surface 32 and the butting surface 33 of the second fireproof frame 3 can still be used to arrange a plurality of fireproof rubber strips on the Appropriate location, in order to greatly improve the smoke shielding ability and enhance the overall fire safety.

Please also refer to the ninth to the thirteenth figures, which are the three-dimensional perspective views to the smoke shielding schematic diagrams (3) of still another preferred embodiment of the new model.

This shows that the new model is suitable for different environments .

As shown in Figures 10 and 11, the side of the fire door 5 adjacent to the second vertical frame 35 has a concave portion 53, so the second shaft member 4 is arranged in the concave portion 53, which can well hide the The two shaft members 4, especially when the fire door 5 is in the closed position, can almost completely hide the second shaft member 4, and then cooperate with the cover member 531 to cover the inner recess 53 where there is no second shaft member 4, so that the fire door can be completely hidden. 5. In the second open position, the exposed area of the inner recess 53 can be reduced, and the appearance can be enhanced. In addition, the fire door 5 is provided with an electromagnetic buckle type locking member 8, so that when the fire door 5 is in the normal open state, the fire door 5 can be fixed on the side of the wall W by the locking member 8, and an electric control element 81 is arranged. The electronic control element 81 is an electronic device with a fire alarm detection function such as a signal receiver or a smoke sensor. The first time a fire occurs, the locking member 8 is automatically unlocked, and the controlled hinge 21 moves to automatically close the fire door 5 . The fire door 5 is also provided with a hidden door bow 7. After the user pushes the fire door 5 to the second opening position and passes through, the hidden door bow 7 can be used to automatically return the fire door 5 to the closed position. In order to avoid the time to close the fire door 5 when escaping in a hurry, the fire door 5 cannot function.

As shown in Figure 10, Figure 12 and Figure 12A, the first sealing member 61 is disposed on the first horizontal frame 11 and the first vertical frame 12 of the first fireproof frame 1 at the same time, and the second The sealing member 62 is disposed on the second horizontal frame 34 and the second vertical frame 35 on the front surface at the same time. Therefore, the first sealing member 61 can further prevent the smoke from escaping from the gap between the first horizontal frame 11 and the rear side of the fire door 5 . The second sealing member 62 can further prevent the smoke from escaping from the gap between the second horizontal frame 34 and the front side of the fire door 5 (the smoke is indicated by an arrow in Figure 12A), and the movable sealing member 63 shields the fire door 5 The gap between the bottom and the ground can achieve the effect of three-sided smoke shielding, so as to greatly improve the smoke shielding ability. As shown in Figure 13, because the fire door 5 of this embodiment is a double door, there may be a gap between the first door leaf 51 and the second door leaf 52, so the third sealing member 9 is used to cover it, so as to further achieve fire protection. For the effect of shielding smoke from the four sides of the door 5, the third sealing element 9 in this embodiment is arranged on the fire door 5 by a combination of a metal sheet 91 and a fireproof rubber strip 92, and the number is taken as an example, and they are respectively arranged on the fire door 5 front and rear sides.
