Description

Fireproof smoke-proof heat-insulation door sheet

Technical Field

The present invention relates to a fire-proof, smoke-proof and heat-insulation door leaf, and more particularly to a rolling door and a door leaf thereof, which are installed in a building and matched with a rolling door machine.

Background

The conventional fire-proof rolling door is only filled with fire-proof material in the rolling door sheets, such as taiwan patent publication No. I371521, "door sheet member, fire-proof heat-insulation door sheet and rolling door", publication No. I668360, "fire-proof heat-resistant smoke-shielding rolling door sheet structure", publication No. M450612, "improved structure of heat-resistant fire-proof rolling door sheet", publication No. M405475, "improved structure of heat-resistant fire-proof rolling door sheet", publication No. M512058, "improved structure of fire-proof rolling door sheet", and so on. However, this method cannot completely block heat conduction, because the two metal door panels are embedded into each other, and high temperature can be transmitted to all the door panels by heat conduction, so the effect of completely blocking heat cannot be achieved.

Furthermore, recently, in order to solve the above-mentioned heat conduction problem caused by the direct contact of the metal door sheets, many heat insulation technologies have been applied to the rolling door sheets, such as taiwan patent publication No. M437372, "fire-proof rolling door sheet structure", and No. M585827, "fire-proof heat-resistant door sheet and rolling door using the same. However, the above-mentioned thermal insulation technology only uses the thermal insulation material to insulate between the front and rear metal door panels, so that the heat conduction problem can be effectively blocked, but the assembly of the door panel is too complicated, and the metal door panels and the thermal insulation material need to be connected by screws or rivets, and the heat may still be conducted through the screws or rivets.

Therefore, the rolling door slat with simple structure and convenient assembly and capable of completely blocking heat conduction is a urgent need for the industry and the public.

Disclosure of Invention

The main object of the present invention is to provide a fire-proof, smoke-proof and heat-insulation door leaf and a rolling door having the same, so as to completely block the heat conduction between the front and rear door leaves, thereby achieving the effect of completely insulating heat, and effectively preventing smoke from passing through the gap between the door leaves, and the door leaf is easy to assemble, low in cost, high in reliability and long in service life.

In order to achieve the above object, the present invention provides a fire-proof, smoke-proof and heat-insulation door sheet, which mainly comprises a first shell, a second shell, and an intermediary heat-insulation body; the first shell comprises an upper pivot part, an upper clamping part, a lower pivot part and a lower clamping part, wherein the upper pivot part and the lower pivot part are respectively positioned at two corresponding side ends of the first shell, the upper clamping part is adjacent to the upper pivot part, and the lower clamping part is adjacent to the lower pivot part; the second shell comprises a first clamping part and a second clamping part, and the first clamping part and the second clamping part are respectively positioned at two corresponding side ends of the second shell; the intermediate heat-insulating body comprises an upper coupling part and a lower coupling part, the upper clamping part of the first shell and the first clamping part of the second shell are fixed on the upper coupling part, and the lower clamping part of the first shell and the second clamping part of the second shell are fixed on the lower coupling part, so that the intermediate heat-insulating body is arranged between the first shell and the second shell; the first shell and the second shell are isolated from each other by the intermediary heat insulation body so as to block heat conduction.

As mentioned above, the fireproof, smoke-proof and heat-insulation door sheet of the present invention mainly separates the first housing from the second housing through the intermediary heat-insulation body, and thereby blocks the heat conduction between the two housings; moreover, the first shell and the second shell are directly assembled on the intermediate heat-insulating body, other connecting auxiliary components are completely not needed, the structure is quite simple, the assembly is quite convenient, and the safety and the reliability are realized; above all, the effects of fire prevention and complete blocking of heat conduction can be achieved.

Detailed Description

Before the fire-proof, smoke-proof and heat-insulation door slats and the rolling door having the same are described in detail in the present embodiment, it should be particularly noted that similar components will be denoted by the same reference numerals in the following description. Moreover, the drawings of the present disclosure are for illustrative purposes only and are not necessarily to scale, nor are all details presented in the figures.

Referring to fig. 1 and fig. 2, fig. 1 is a sectional view of a first embodiment of the fire-proof, smoke-proof and heat-insulation door sheet of the present invention, and fig. 2 is a sectional exploded view of the first embodiment of the fire-proof, smoke-proof and heat-insulation door sheet of the present invention. The fire-proof, smoke-proof and heat-insulation door leaf 1 as shown in the figure is mainly composed of three components, namely a first shell 2, a second shell 3 and an intermediate heat-insulation body 4.

The first housing 2 includes an upper pivot portion 21, an upper engaging portion 23, a lower pivot portion 22, and a lower engaging portion 24, wherein the upper pivot portion 21 and the lower pivot portion 22 are respectively located at the upper and lower ends of the first housing 2, the upper engaging portion 23 is adjacent to the upper pivot portion 21, and the lower engaging portion 24 is adjacent to the lower pivot portion 22.

To explain, the first casing 2 includes an upper surface 201, a lower surface 202, and a side surface 203, and the upper pivot portion 21 is integrally wound around the first casing 2 to form a hook shape, and protrudes from the upper surface 201 in a direction away from the lower pivot portion 22, that is, upward and protrudes out of the upper surface 201. In addition, the lower pivoting portion 22 is also integrally formed by winding the first casing 2 into a hook shape, and protrudes from the side surface 203 toward the direction away from the lower engaging portion 24, and the lower end edge of the lower pivoting portion 22 is flush with the lower surface 202, i.e., protrudes toward the inner side of the door panel.

Furthermore, the first housing 2 of the present embodiment further includes a retaining protrusion 25, which is formed by integrally bending and protruding the first housing 2 from the side surface 203 toward the same direction as the lower pivoting portion 22, and the retaining protrusion 25 is adjacent to the lower pivoting portion 22, and the height of the retaining protrusion 25 protruding from the side surface 203 is greater than the height of the lower pivoting portion 22 protruding from the side surface 203. Therefore, when the door panels are connected in series, i.e. the lower pivoting portion 22 and the upper pivoting portion 21 of another door panel are pivoted with each other, the anti-slip protrusion 25 can stop the upper pivoting portion 21 of the other door panel from separating from the upper opening of the lower pivoting portion 22, as shown in fig. 3.

As shown in the figure, the upper engaging portion 23 and the lower engaging portion 24 of the present embodiment are formed by bending two corresponding ends of the first housing 2 in a direction toward each other. Accordingly, it is quite obvious that all the structures on the first housing 2, including: the upper pivot portion 21, the lower pivot portion 22, the upper engaging portion 23, the lower engaging portion 24, and the retaining projection 25 are formed by integrally bending the first housing 2, and thus the manufacturing is easy.

On the other hand, the second housing 3 includes an upper surface 301, a lower surface 302, a side surface 303, a first engaging portion 31, a second engaging portion 32, and a smoke blocking tab 304; the first engaging portion 31 and the second engaging portion 32 are respectively located at two corresponding sides of the second housing 3, namely, at the upper surface 301 and the lower surface 302. Further, like the upper engaging portion 23 and the lower engaging portion 24 of the first housing 2, the first engaging portion 31 and the second engaging portion 32 of the second housing 3 are formed by bending two corresponding ends of the second housing 3 in a direction toward each other.

Furthermore, the smoke barrier tab 304 of the present embodiment protrudes from the lower surface 302 in a direction away from the upper surface 301, that is, downward, and the smoke barrier tab 304 protrudes out of the side surface 303. Thereby, when the door panels are connected in series, the smoke barrier tab 33 does not cause a hindrance to the engagement of the upper and lower door panels with each other, and the flow of smoke from the air gap between the door panels can be effectively blocked, as shown in fig. 3.

The intermediate thermal isolator 4 of the present embodiment includes an upper end surface 401, a lower end surface 402, an upper coupling portion 41, and a lower coupling portion 42, wherein the upper coupling portion 41 of the present embodiment includes a first upper slot 412 and a second upper slot 413 disposed on the upper end surface 401, and the lower coupling portion 42 includes a first lower slot 422 and a second lower slot 423 disposed on the lower end surface 402. Accordingly, the upper engaging portion 23 and the lower engaging portion 24 of the first housing 2 are respectively fitted in the first upper engaging groove 412 and the first lower engaging groove 422, and the first engaging portion 31 and the second engaging portion 32 of the second housing 3 are respectively fitted in the second upper engaging groove 413 and the second lower engaging groove 423. That is, the thermal conduction can be blocked by firmly attaching both sides of the intermediate heat interrupting body 4 by the structural stress of the first and

second cases

2 and 3 themselves, and also thereby isolating them from each other.

Referring now also to FIG. 3, there is shown a partial cross-sectional view of a preferred embodiment of the present tambour door; as shown in the figure, the rolling door of the present embodiment is formed by connecting a plurality of fire-proof, smoke-proof and heat-insulation door slats 1 in series according to the previous embodiments; the adjacent door panels 1 are pivotally connected to each other by the upper pivot portion 21 and the lower pivot portion 22 of the first casing 2, and the smoke blocking tab 304 of the second casing 3 partially covers the lower door panel. That is, when the rolling door falls down, the smoke barrier tab 304 can just cover the air gap between the two door leaves, so as to form a barrier between the two door leaves, and completely prevent smoke from passing through the gap between the two door leaves, thereby achieving the effect of preventing smoke from diffusing.

Moreover, as shown in fig. 3, when the rolling door falls, the first casing 2 and the second casing 3 of this embodiment do not directly contact, the first casing 2 of this embodiment still contacts the first casing 2 only with the upper and lower lamellae 1, and the second casing 3 contacts the second casing 3 only with the upper and lower lamellae 1. Therefore, when a fire actually occurs, the heat source from the inner side or the outer side of the door leaf 1 is not transmitted to the other side through the heat conduction between the metal door leaves of the first casing 2 and the second casing 3, but the heat conduction is completely blocked by the intermediate heat blocking body 4, so as to achieve the effects of heat blocking and fire prevention.

In summary, the present invention fixes the first housing 2 and the second housing 3 by using the clamping groove method, and the assembly can be completed by aligning the upper clamping portion 23 and the lower clamping portion 24 of the first housing 2, and the first clamping portion 31 and the second clamping portion 32 of the second housing 3 with the first upper clamping groove 412, the second upper clamping groove 413, the first lower clamping groove 422, and the second lower clamping groove 423 of the intermediate heat blocking member 4, respectively, and pushing the clamping portions into the clamping grooves, and further, there is no directional limitation on the intermediate heat blocking member 4, and the manufacturing process is simple, safe, reliable, and durable, and more importantly, the heat transmission and the smoke spreading can be completely blocked.

Referring to fig. 4 and 5, fig. 4 is a sectional view of a second embodiment of the fire-proof, smoke-proof and heat-insulation door slat of the present invention, and fig. 5 is a partial sectional view of a roll-up door formed by the door slats of the second embodiment. As shown in the figure, the main differences between the second embodiment and the first embodiment include: the upper coupling part 41 and the lower coupling part 42 have different forms, different means for blocking smoke, and the lower pivot part 22 of the first housing 2 is partially recessed.

To explain, the upper coupling portion 41 and the lower coupling portion 42 of the present embodiment respectively employ the larger upper recess 411 and the larger lower recess 421, so that the assembly process is more convenient, and the upper engaging portion 23 and the first engaging portion 31 can be more easily inserted into the upper recess 411, and the lower engaging portion 24 and the second engaging portion 32 can be more easily inserted into the lower recess 421.

Further, a smoke blocking groove 33 is recessed in a position corresponding to the first engaging portion 31 on the side end surface of the second housing 3, and a smoke blocking protrusion 34 is recessed downward in a position corresponding to the smoke blocking groove 33 on the lower side of the second housing 3. The smoke blocking groove 33 is recessed from the outer side end surface of the second housing 3, and the smoke blocking protrusion 34 protrudes from the lower surface of the second housing 3 in a direction away from the smoke blocking groove 33, that is, extends downward from the lower edge of the side end of the second housing 3.

On the other hand, a first side opening groove 43 is formed in the intermediate heat insulation body 4 corresponding to the lower pivoting portion 22 of the first shell 2; a second side open slot 44 is arranged in the middle heat insulation body 4 corresponding to the smoke blocking groove 33; the first side opening slot 43 is used for partially accommodating the lower pivoting portion 22 of the first housing 2, and the second side opening slot 44 is used for accommodating the smoke blocking groove 33 of the second housing 3.

It should be noted that, in the cross-sectional view of the intermediate heat insulating body 4 of the present embodiment, the first side opening groove 43 and the second side opening groove 44 are identical in size and are arranged diagonally, and are substantially symmetrical with respect to the diagonal line of the cross-sectional view, so when the first housing 2 and the second housing 3 are assembled on the intermediate heat insulating body 4, it is only necessary to align the lower pivot portion 22 of the first housing 2 with one of the first side opening groove 43 and the second side opening groove 44 and align the smoke blocking groove 33 of the second housing 3 with the other one of the first side opening groove 43 and the second side opening groove 44 without particularly positioning the intermediate heat insulating body 4 in a specific orientation, and the assembling process is quite simple.

In addition, as shown in fig. 5, it is a partial sectional view of the roll-up door constructed by the lamellae 11 of the second embodiment; as shown in the drawings, the rolling door of the present embodiment is formed by connecting a plurality of fire-proof, smoke-proof and heat-insulation door slats 11 of the second embodiment in series; wherein, the adjacent door sheets 11 are coupled with each other by the smoke blocking groove 33 and the smoke blocking convex 34 of the second housing 3; that is, when the rolling door falls down, the smoke-blocking protrusion 34 can be just completely accommodated in the smoke-blocking groove 33, so that a barrier is formed in the gap between the two door leaves, smoke can be completely prevented from passing through the gap between the two door leaves, and the effect of preventing smoke from diffusing can be achieved.

Please refer to fig. 6, which is a cross-sectional view of a third embodiment of the fire-proof, smoke-proof and heat-insulation door sheet of the present invention. The third embodiment of the present invention differs from the foregoing second embodiment mainly in that the upper surface 301 and the lower surface 302 of the second housing 3 of the present embodiment each form a high shoulder 35, while the corresponding sides of the upper surface 201 and the lower surface 202 of the first housing 2 each form a low shoulder 26. In other words, the upper pivoting portion 21 and the lower pivoting portion 22 of the present embodiment are located at about the middle position between the upper and lower sides of the door leaf body, and the left and right sides thereof have a low shoulder portion 26 and a high shoulder portion 35, respectively, and the upper pivoting portion 21 and the lower pivoting portion 22 are directly adjacent to the low shoulder portions 26.

Referring to fig. 7, a partial cross-sectional view of a rollup door formed by third embodiment of slats 111 is shown, wherein the rollup door of this embodiment is formed by serially connecting a plurality of fire-proof, smoke-proof and heat-insulation slats 111 according to the third embodiment. In addition, in the door sheets 111 connected in series up and down, the directions of the adjacent door sheets 111 are opposite to each other; that is, taking fig. 7 as an example, the opening directions of the upper pivoting portion 21 and the lower pivoting portion 22 of the upper door piece 111 are directed to the right side, and the opening directions of the upper pivoting portion 21 and the lower pivoting portion 22 of the lower door piece 111 are directed to the left side. In this way, the upper and lower door panels can be connected and hooked to each other.

In addition, in the present embodiment, the adjacent door sheets 111 are pivotally connected to each other by the upper pivot portion 21 and the lower pivot portion 22 of the first housing 2, and the adjacent door sheets are coupled to each other by the high shoulder portion 35 of the second housing 3 and the low shoulder portion 26 of the first housing 2; that is, when the rolling door falls down, the high shoulder 35 of the second housing 3 and the low shoulder 26 of the first housing 2 form a barrier in the gap between the two slats, so as to completely prevent smoke from passing through the gap between the two slats, thereby achieving the effect of preventing smoke from spreading.

On the other hand, the upper pivot portion 21 and the lower pivot portion 22 correspond to the upper coupling portion 41 and the lower coupling portion 42. That is, as shown in fig. 7, when the door leaf falls, the upper pivoting portion 21 and the lower pivoting portion 22 can be accommodated in the upper coupling portion 41 and the lower coupling portion 42 respectively and isolated from each other. Accordingly, in the door slats 111 connected in series up and down, the first housing 2 and the second housing 3, which are also located on the left side of the rolling door, do not directly contact with the first housing 2 and the second housing 3, which are also located on the right side of the rolling door, so that there is no heat conduction function when a fire occurs, and the high heat temperature can be completely blocked, thereby achieving the effects of heat resistance and fire prevention.

The above-described embodiments are merely exemplary for convenience of description, and the scope of the claims of the present invention should not be limited to the above-described embodiments.
