Heat-resistant fireproof roll door structure improvement

This creation is related to a high resistance to deformation, and the door rail lifting action is smoother and the door can be improved to achieve better heat resistance.

According to the heat-resistant fire-proof roll door, the heat-resistant material is filled in each fire-proof roll door to alleviate the heat penetration and achieve the heat-blocking effect; as used in Taiwan Patent Publication No. M405475 "heat-resistant fireproof roll door structure" "This is a modified creation of the patent application for the Taiwan Patent Application Publication No. 201109514 "Improvement of Heat-Resistant Fire-Proof Rolling Door Structure", which has caused a bending deformation and a fire-resistant heat-resistance failure; The distance between the axis of the hook-shaped folded portion and the one side is short, and the hook-shaped folded portions are bent in the same direction, so that the weight of the connection can be withstood in the series connection, and the bending and deformation can be reduced to achieve better. The heat-resisting and fire-resisting effect, only in the implementation, the series connection between the two or two rolls of the door must be in the form of a forward and reverse form to form a door curtain, which makes the axis of the hook and eye not fall on the same line, It is not located on the center line between the first and second sections, causing the skewed door pieces to be slanted in series. (Because the center of gravity is unstable or there is no righting guide due to the rolled door itself) In this case, when each roll of door enters the lift rail Being guided back, it will cause excessive collision and friction with the door rail. In addition to affecting the smoothness of the lifting movement, it will also affect the smoothness or reliability of the movement of each roller door piece in the door rail. There are concave arc faces on both sides of the rolling door piece, because the rolled door piece is overlapped and closed in the door rail, because of the concave curved face There will be gaps between the door rails and the door rails, so that the space on both sides of the door curtain is not easy to require complete airtightness, which affects the fire source temperature or the barrier property of smoke intrusion.

The main purpose of the present invention is to provide an improved structure of the heat-resistant fireproof roll door, wherein a roll of the door piece is joined by the first piece and the second piece to form a chamber, and the heat-insulating material is filled in the chamber. The main part is that the piece has an inner end surface, and a concave curved portion is formed on the surface of the inner end surface, and the upper and lower ends are bent outward to form an upper inner fold surface and a bottom inner fold. a front surface of the upper inner folding surface having a first upper hanging portion bent upwardly and then bent inwardly and downwardly, and a front end of the bottom inner folding surface is opposite to the first hanging portion The lower oblique angle of the upper end of the upper portion is formed by a first pull-down portion corresponding to the first upper hanging portion; the second segment and the first segment are mutually engaged to form a chamber for filling the heat-resistant material , having an outer end plane, the upper and lower ends of the outer end plane, each bent inwardly, having an upper outer folded surface and a bottom outer folded surface, the upper outer folded surface, the height of which is slightly lower than the first section The height of the upper inner fold face, and the inner end is opposite to the shape of the first upper hanging portion of the first segment, a second hanging portion that is connected to the upper hanging portion and combined by the splicing of the first and second hanging portions to form a door hook with a blink, and the bottom outer folding portion and the upper and outer folding portions The distance is equivalent to the distance between the upper inwardly folded surface and the bottom inwardly folded surface of the first segment, and the inner end extends upward to form a meandering portion, forming a guiding surface parallel to the outer end plane and generating an activity. a space, and the end of the beak portion has a second pull-down portion that is parallel to the first pull-down portion and is connected by the first and second pull-down portions with respect to the shape of the first pull-down portion of the first segment Combine to form a piece of hook, and the door pulls The hook has a hoe corresponding to the mortise of the door piece hook; and between the two pieces of the door piece of the majority of the rolling door piece, the door piece hook is laterally inserted into the movable space and the door piece hook is used for the interlocking cooperation. The door curtain of the fireproof roll door is completed; by each roll piece, the force acting point of the first upper hanging portion and the first pull-down portion of the first segment is the same as the distance of the inner end face, and The force acting points of the second upper hook portion and the second pull-down portion of the two segments are the same as the distance between the outer end planes, and even the first and second upper hanging portions and the first and second pull-down portions are formed. The hook point of the hook hook and the hook of the door hook is the same as the center line between the inner end surface and the outer end plane, which causes the first and second pieces to complement each other and improve the door hook and the door hook. The anti-deformation ability; in addition to the serially connected roll pieces in the chassis, the door can be strongly supported by the non-deformable door pull hooks, so that there is no release between the roll pieces on the reel In addition to the coiling and winding action, when each of the roll sheets enters the door rail, the door hooks are pulled between each roll door. The head concentric buckle pulls the door hook and blinks, and uses the pulling force to be evenly located on the center line of the rolling door piece, and cooperates with the guide to face the door piece hook for linear straightening guidance, so that each roll door is at The lifting action in the door rail does not swing, which increases the smoothness of the lifting and lowering displacement of the rolling door piece, especially when the successively rolling door pieces successively enter the door rail to descend and close the door closing action, the door piece hook is in the movable space. The process of moving up and away from the door hook is further guided by a straight line guiding the side of the door hook, so that the bottom inner fold surface and the bottom outer fold surface are smoothly adhered to the inner fold face and the upper outer fold face. The sealing effect, in addition, the outer surface of the second segment of each roll can be flat against the door rail to achieve a comprehensive sealing of the door curtain as a whole, thereby exerting a more effective heat-blocking effect.

The second purpose of this creation is to provide an improved structure of the heat-resistant fireproof roll door. The second upper hanging portion of the second segment is combined with the first upper hanging portion of the first segment to form a door hook with a blink, and the tail end of the second hanging portion is The back hook portion of the first hanging portion is bypassed, and the first hook portion and the second hook portion are combined and joined by the hook portion of the first hook portion. Fixed time.

A further object of the present invention is to provide an improved structure of a heat-resistant fireproof roll door, wherein a second pull-down portion of the second segment is joined in parallel with a first pull-down portion of the first segment to form a a hook of the first piece of the head, the tail end of the first pull-down portion has a reverse hook portion that rewinds the second pull-down portion, and the second pull-down portion is clamped by the back hook portion , 俾 can increase the fixation of the first pull-down portion and the second pull-down portion when combined.

The structure of the heat-resistant fireproof roll door is improved. As shown in FIG. 1 and FIG. 2, a roll piece 10 is mutually engaged by the first piece 11 and the second piece 12 to form a chamber 13 and is inside the chamber 13.
