Description

  The present invention relates to a joinery that is provided at an opening of a building and is formed of an extruded aluminum material.

JP 2014-109091 A

In the field of joinery, joinery made of aluminum alloy with excellent corrosion resistance, light weight, and excellent workability has been developed for a long time. Currently, aluminum is not mainstream in terms of strength. In a long frame material such as a large window, a frame material or the like, reinforcement has been performed by a steel reinforcing member having a strength higher than that of aluminum.
In recent years, joinery is required to have high fireproof performance. For joinery made of an aluminum alloy whose melting point is lower than that of iron, a steel reinforcing member is provided so as not to cause harmful deformation in fireproofing. (For example, “Explanation of standard specifications for fire doors made of aluminum alloy” issued in 2002 by the Association of Curtain Walls and Fire Protection Openings, etc.) A fitting has been developed in which a reinforcing member made of steel is disposed on the frame material to prevent deformation such as melting of the frame material and collapse of the shoji in a fire.
In this way, in conventional joinery, making use of the characteristics of the material of aluminum to form a joinery that is lightweight and has excellent workability and operability, the weakness of being made of aluminum is compensated by a steel reinforcing member. And, it was strong and excellent in fire resistance, and formed a fitting that was well balanced as a whole.

However, strengthening joinery made of aluminum alloy with steel reinforcing members means that the presence of iron reinforcing members may adversely affect the intrusion of flames, smoke, toxic gases, etc. in the initial stage of a fire. There was sex.
That is, the reinforcement as shown in the prior art document is usually performed by fixing a steel reinforcing member with a screw or the like at a fixed position set at predetermined intervals with respect to the aluminum brazing material. However, since the thermal expansion coefficient of aluminum is about 1.9 times higher than that of iron, when the firewood stretches due to heat in the early stage of fire, the elongation is fixed between the fixed positions by the steel reinforcing member. There is a possibility that the splitting material limited in elongation and stretched may be bent. Then, due to the bending of the brazing material, the hermetic material provided on the brazing material is separated from the frame material, and the airtightness between the window frame and the shoji is impaired at the initial stage of the fire. There was a risk of gas intrusion.
In addition, for large fittings, it was inevitable that the shoji would become heavier by reinforcing the shoji frame with a steel reinforcing member.

  The present invention can solve the above-mentioned problems and the like, and when reinforcing the shoji of an aluminum shoji, etc., a research on the reinforcing member, which has been conventionally made of steel, has been made anew. In addition, it is found that the same aluminum alloy as that of the eaves and the like can be reinforced, and it is possible to provide a joinery that can suppress adverse effects caused by the difference between the eaves and the material of the reinforcement member.

And a shoji that is supported so as to be openable and closable with respect to the window frame. A reinforcing member made of metal is fixed.

(Features of joinery of embodiment of the present invention)
The joinery of the above embodiment of the present invention is characterized in that the reinforcing member disposed in the hollow portion of the vertical wall main body portion made of an aluminum shape is made of aluminum.
When reinforcing a frame member or a frame member (for example, a summon bowl 34) made of an aluminum shape with a reinforcing member, as shown in FIG. 4B, strength and heat resistance that can compensate for the weakness of aluminum. It is usual to use a reinforcing member s made of a steel material such as high steel. Even if the steel reinforcing member s is not used, it has been common knowledge that the reinforcing member is formed of a material having at least the same strength or heat resistance as that of aluminum and is fixed to the frame material or the brazing material.
Considering that the frame material and the brazing material are reinforced with aluminum, which is the same material, as shown in FIG. 4 (a), the thickness of the frame material and the brazing material is added to the thickness of the reinforcing member. The formation of the thick portion is advantageous from the viewpoint of manufacturing and cost, and it has not been considered at all to reinforce the frame material and the brazing material by separately forming the aluminum reinforcing member.

  The joinery of the embodiment of the present invention uses a steel material such as steel as a reinforcing member by reinforcing an aluminum reinforcing member that is not normally employed when reinforcing a frame member or a frame member made of an aluminum shape. The present inventors have found that the problems caused by this can be solved, and that sufficient flame shielding performance can be ensured in the event of a fire.

-Temperature simulation-
Simulation of how temperature changes occur in firewood reinforced with aluminum reinforcement members in order to infer the superiority of reinforcement with aluminum reinforcement members over reinforcement with steel reinforcement members Analysis was performed.
The simulation was performed using general-purpose CFD (computational fluid dynamics) software. The calculation was performed in two dimensions and an unsteady radiant heat conduction analysis was performed. Air is essentially a fluid, but in the calculation, calculation is performed as a solid. As a boundary condition, a temperature at a position 100 mm away from the analysis target was set as a temperature according to a temperature curve according to the standard heating curve (ISO834), and radiant heat from that portion was set to be given to the heating surface of the brazing material. The heat dissipating surface is set as a model that performs at a temperature (20 ° C) and heat transfer coefficient (5 W / (m ² · K)) assuming heat transfer from the outside. The temperature of the member was determined. The standard heating curve used (ISO834) is shown in FIG.

  In the simulation, as an embodiment of the present invention, a reinforced material (case 1) reinforced using a 2 mm thick aluminum reinforcing member a, and a steel reinforcing member s 1.6 mm thick as a comparison object. Reinforcement member integrated case material (case 2) with a reinforcing fire sash and a reinforcing member integrated type made up of a thick wall material kt to which a thickness t (2 mm) equivalent to an aluminum reinforcement member is added (case 2) I went about case3).

FIGS. 6A to 6C show the configurations of the brazing material k, the thick-walled brazing material kt, and the reinforcing members a and s used in the cases 1 to 3.
For the basic material k used in the simulation, the basic part is assumed to be a hollow structural material with a rectangular cross-section of 31.4 (expected size) mm x 20.0 (finding size) by modeling the summon of a shoji screen. The one surface of the finding surface was the heating surface and the other surface was the heat dissipation surface. The thickness of the finding surface on the heating surface side is 2.3 mm, the expected surface on the side where the reinforcing member is not fixed and the thickness of the heat radiating surface are 1.1 mm, and the expected surface thickness on the side where the reinforcing member is fixed is 1 0.0 mm. As for the inner diameter of the hollow portion of the brazing material, the expected dimension is 28.0 mm, and the found dimension is 17.9 mm.

The reinforcing member a used for the case 1 is a substantially U-shaped plate made of aluminum having a thickness of 2.0 mm, the expected dimension is 27.0 mm, and the found dimension is 16.9 mm. One side wall a2 of the U-shaped plate member has a fixing portion a4 for fixing to the saddle member.
The reinforcing member s used for case 2 is a steel U-shaped plate material with a thickness of 1.6 mm, and the expected size is 27.0 mm and the found size is 16.9 mm, similar to the aluminum reinforcing member a of case 1. did. One side wall s2 of the U-shaped plate member has a fixing portion s4 for fixing to the saddle member.
The reinforcing members a and s of case1 and case2 are inserted with the substantially U-shaped bottom portions a1 and s1 facing the finding surface on the heating surface side of the brazing material k, and fixing the substantially U-shaped one side walls a2 and s2. The portions a4 and s4 are fixed in close contact with the prospective surface on one side of the brazing material, and a space d2 of 0.5 mm is set for the portions other than the fixed portion, assuming non-contact due to surface irregularities or the like.

Further, between the bottom portions a1 and s1 of the reinforcing members a and s and the finding surface on the heating surface side of the brazing material k, and a prospective surface on the other side of the other side walls a3 and s3 of the reinforcing members a and s and the brazing material k. Is set to a distance d1 of 1.0 mm. By setting the interval d1 of 1.0 mm, it becomes difficult for the heat of the brazing material k to be directly transmitted to the reinforcing members a and s, and the temperature rise of the reinforcing members a and s can be suppressed.
The interval d1 of about 1.0 mm can also be assumed as play that is required when the reinforcing members a and s are inserted into the rib k.
Both ends of the reinforcing members a and s on the heat radiating surface side are brought into close contact with the finding surface on the heat radiating surface side of the brazing material k.
The brazing material kt used for case 3 is 4.3 (= 2.3 + 2.0) mm in which the thickness of the finding surface on the heating surface side is increased by the thickness dimension of the reinforcing member a, and similarly, the reinforcing member is not fixed. The thickness of the prospective surface on the side and the heat dissipation surface is 3.1 (= 1.1 + 2.0) mm, and the thickness of the prospective surface on the side on which the reinforcing member is fixed is 3.0 (= 1.0 + 2.0) mm. It was.

The reason why 1.6 mm was selected as the thickness of the reinforcing member s for case 2 to be compared is that workability (ease of bending) and workability as a reinforcing member placed in a cage from standard steel materials This is the same as the reinforcing member used in a conventional fire sash.
The reason why 2.0 mm was selected as the thickness of the reinforcing member “a” of the case 1 according to the embodiment of the present invention was selected based on whether the weight advantage over the case 2 could be sufficiently exhibited.
Specifically, when it is actually formed as a reinforcing member (length = 1261 mm), it is less than half of the reinforcing member (mass: about 1.054 kg) made of steel material with a thickness of 1.6 mm in case 2. As the mass reinforcing member, an aluminum reinforcing member (mass: about 0.445 kg) having a thickness of 2.0 mm was used.

  For each case, the heating surface temperature A1 to A3, the reinforcing member temperatures B1 to B3 and the radiating surface temperatures C1 to C3 of the firewood shown in FIGS. 6 (a) to 6 (c) are determined every 5 minutes from the start of heating, The results are summarized in Table 1.

From Table 1 above, the following points can be understood.
(1) For case 2 reinforced with a steel reinforcing member s, the heating surface temperature A2 of the brazing material k is 391.9 ° C. at the point of 10 minutes from the start of heating, whereas the reinforcing member temperature B2 is The temperature is 370.1 ° C., and it is considered that there is a difference between the thermal elongation of the aluminum brazing material k and the thermal elongation of the steel reinforcing member s.
Specifically, assuming that the length of the brazing material k is 2000 mm, the thermal expansion coefficient of aluminum (23.0 (10 ⁻⁶ / ° C.)) and the thermal expansion coefficient of steel (12.1 (10 ⁻⁶ / ° C.)) )), The thermal elongation of the brazing material portion is 17.1 mm (= 23.0 × 10 ⁻⁶ × 2000 × (391.9-20)), whereas the heat of the steel reinforcing member s is The elongation is 8.5 mm (= 12.1 × 10 ⁻⁶ × 2000 × (370.1-20)), and a difference in thermal elongation of about 10 mm occurs.
On the other hand, in case 1 according to the present invention, the reinforcing member a is the same material as the brazing material k, so that there is almost no difference between the thermal elongation of the reinforcing member a and the thermal elongation of the brazing material k. Specifically, the thermal expansion of the brazing material k is 15.6 mm (= 23.0 × 2000 × (359.0-20)), whereas the thermal expansion of the aluminum reinforcing member a is 14. 7 (= 23.0 × 2000 × (340.2-20)), and the difference in thermal elongation remains at 1 mm or less.

(2) After 30 minutes from the start of heating, the case 1 which is an embodiment of the present invention has a heating surface temperature A1 of 642.2 ° C and a reinforcing member temperature B1 of 611.9 ° C. The case 2 reinforced by the steel reinforcing member s has a heating surface temperature A2 of 671.0 ° C. and a reinforcing member temperature B 2 of 650.1 ° C., both of which are higher than the case 1 Has reached. This is considered to be caused by differences in the volume of the steel reinforcing member s, the specific heat of the material, the thermal conductivity, and the like.
Since the melting point of steel is 1539 ° C., the reinforcing member s does not melt, but the heating surface temperature A2 of the brazing material k exceeds the melting point of aluminum (660 ° C.). After 30 minutes from the start of heating, the aluminum brazing material k starts to melt.
(3) In case 3 in which the brazing material kt is formed as an integral body of aluminum, the reinforcing member temperature C3 is substantially the same as the heating surface temperature A3, whereas in case 1 which is an embodiment of the present invention, Although the heating surface temperature A1 is higher than that of case 3, the reinforcing member temperature B1 is suppressed to about 10 ° C. lower than the reinforcing member temperature B3 of case 3 until 30 minutes after the start of heating.
It is considered that the heat transfer to the reinforcing member a is hindered by the contact thermal resistance and the gap between the brazing material k and the reinforcing member a, and the temperature rise of the reinforcing member a is suppressed.
By suppressing the temperature rise of the reinforcing member a, the reinforcing member a is delayed from reaching the melting temperature.
As mentioned above, it is a guess by simulation, and the above-mentioned phenomenon does not necessarily appear in an actual dredging material, but it is considered that the same tendency is observed in an actual dredging material.

As can be inferred from the verification by the above simulation, as shown in FIG. 4 (b), in order to improve the strength of the firewood in the event of a fire, the steel reinforcing member s is fixed in the hollow portion of the firewood k. Then, in the event of a fire, the reinforcing member s fixed in the hollow portion of the brazing material k remains and the shape of the shoji remains for a predetermined time even if the outdoor wall of the brazing material (summoning kite) k is directly exposed to the flame and melts. Can be maintained. However, even if the reinforcing member s is maintained, it is not preferable that the brazing material k melts at an early stage, which leads to communication between the inside and outside of the room.
In addition, since the thermal expansion coefficient of aluminum is much larger than that of steel, when the brazing material k is stretched by heat after the fire breaks out, the stretch is fixed by a screw or the like with the steel reinforcing member s. When the splitting material k which is limited by an interval (for example, 400 mm) and whose elongation is limited is bent, for example, when the saddle material is a door toe, the outdoor side of the metal vertical rod 241 shown in FIG. There was a risk that the airtight material s1 disposed on the door wall 241c would be separated from the right vertical frame 14 and that flames and smoke would enter from the separated portion.

Further, for example, as shown in FIG. 5 (a), a fixing means such as a screw that fixes both the extension Lk of the rib k and the extension Ls of the reinforcing member s (Lk−Ls) is used. A large force is applied, and as a result, the screw hole h provided at the bottom of the glass front opening of the brazing material k spreads to fix the reinforcing member s to form a long hole portion H, and the formed long hole portion There is a risk of leakage of toxic gas generated by burning a sealing agent for sealing the panel body such as glass from H.
In addition, even during normal use, due to the difference in potential between aluminum and steel, potential corrosion may occur in the brazing material k, which is an aluminum shape, due to long-term use of the joinery.

  On the other hand, as shown in FIG. 4 (a), when the thickness t portion is formed by increasing the dimension corresponding to the thickness of the reinforcing member a in order to improve the strength of the brazing material k, the strength at the normal time is obtained. However, in the event of a fire, the outdoor wall portion of the firewood kt is directly exposed to the flame, so that the entire thickness t portion of the outdoor wall portion is directly heated and melted, and the shape of the shoji cannot be maintained.

  On the other hand, as shown in FIG. 4 (c), in order to improve the strength of the firewood (for example, summon firewood) k at the time of fire, a separate member is provided in the hollow portion of the firewood (for example, summon firewood) k. When a certain aluminum reinforcing member a is fixed, in the event of a fire, the outdoor wall of the firewood (e.g., summon firewood) k is directly exposed to the flame and heated, but the reinforcement member a is made of firewood (e.g., firewood) Since it is a separate member from k, the heat of the brazing material (for example, summoned rice cake) k is not directly transferred. And the contact thermal resistance in the contact part of an aluminum material and an aluminum material is larger than the contact thermal resistance in the contact part of an aluminum material and a steel material, and the contact part of the brazing material (for example, summoned rice cake) k and the reinforcement member a In addition, heat is not easily transmitted in the case, and the reinforcing member a disposed in the hollow portion of the brazing material k is disposed at an interval of about 1.0 mm with respect to the inner wall of the hollow portion of the brazing material k. Heat transmission of the brazing material k is suppressed to the aluminum reinforcing member a formed as a separate object from the material k and inserted into the hollow portion.

Accordingly, the reinforcing material a made of aluminum in which the heat transfer from the eaves k is suppressed, although the eaves k directly heated by a flame or the like at the time of a fire increases the surface temperature A1 of the heating surface with the lapse of time. , The temperature rise is suppressed compared with the reinforcement member temperature B3 of the reinforced material kt formed integrally with the reinforcement member portion, the melting point is suppressed, the shape of the shoji can be maintained, and sufficient A good flame barrier performance.
Further, even if heat at the time of fire is transmitted to the aluminum reinforcing member a at the initial stage of the fire and the temperature rises, the reinforcing member a is made of aluminum like the brazing material k. A difference in elongation generated between the member a and the member a can be minimized. Thereby, in the initial stage of the fire, the brazing material k and the reinforcing member a both extend to the same extent, so that the deflection of the brazing material k is suppressed, and in the initial stage of the fire, the airtightness between the brazing material k and the frame and between the brazing materials k. Can be delayed, and an excessive force is not applied to the screw hole or the like for fixing the reinforcing member a, and the formation of the long hole portion H in the screw hole can be suppressed.

As described above, the superiority in the case where the reinforcing member is made of aluminum has been described. However, in order to confirm the performance of the joinery in which the reinforcing member is made of aluminum, a fire test using an actual object was performed.
The fire prevention test was conducted in accordance with Article 2-9 of the Building Standards Act (No. 2 fire prevention equipment specified by fire doors and other government ordinances) and heated using a standard heating curve (ISO834) (FIG. 8).
In the fire prevention test, a reinforcing member 74 made of aluminum and having a thickness of 2 mm is used as the reinforcing member 74 disposed in the summoning cage 34 of the external shoji 3 in FIG. As the reinforcing member 73 and the door rod 24 of the shoji 2 and the reinforcing members 71 and 72 arranged in the summoning cage 23, aluminum reinforcing members having a thickness of 1.5 mm were used.
By using a 1.5 mm aluminum reinforcing member, the mass of the reinforcing member can be reduced to about one third of the steel reinforcing member.

Even after 20 minutes from the start of the test, the shoji does not collapse, and a large flame leak from the gap between the shoji and the saddle cannot be confirmed. I understood that.
When the surface of the heated surface of the shoji cocoon k is confirmed after the fire test, as shown in FIG. 7, the heated cocoon k is in progress of melting. Although the material k was left undissolved, the portion (C) of the brazing material close to the surface to be found melted and the reinforcing member arranged in the hollow portion was exposed. The portion (B) of the found surface of the brazing material k almost melted away, and only the alumite layer remained on the surface.
It was confirmed that the aluminum reinforcing member exposed from the brazing material k remained in the hollow portion of the brazing material in a shape relatively close to the original shape.

As described above, according to the present invention in which the eaves made of an aluminum shape member are reinforced by the reinforcing member made of aluminum made of another member, it is possible to ensure the flame shielding performance in the event of a fire. And the whole can be finished lightweight rather than using a steel reinforcement member.
As an example, in a sash with a waist window size (W1650, H1300), the reinforcing member placed in the downpile is changed from a steel reinforcing member (thickness: 1.6 mm) to an aluminum reinforcing member (external child summoning bowl). By changing the thickness to 2.0 mm, the external shoji door toe bowl and the inner shoji summon bowl, and the door toe bowl: 1.5 mm thick), the mass can be reduced by about 2.3 kg. The total weight of the body can be reduced from 12.2 kg to 9.9 kg.
In addition, in the sash of the terrace size (W1650, H2200), the reinforcing member arranged in the vertical gutter is changed from a steel reinforcing member (thickness 1.6 mm) to an aluminum reinforcing member (for a shoji summon bowl: thickness By changing to 2.0 mm, the external shoji door toe bowl and the internal shoji summon bowl, and the door toe bowl (thickness: 1.5 mm), the mass can be reduced by about 4.0 kg, and the total weight of the box As a result, the weight can be reduced from 18.2 kg to 14.2 kg.

  In addition, since the reinforcing member is made of aluminum, it can be manufactured by extrusion forming of aluminum in the same manner as the brazing material. Therefore, the reinforcing member can be manufactured using equipment for manufacturing the shape member, and the manufacturing cost can be reduced. Can be suppressed. Moreover, it can respond to complicated cross-sectional shape by extrusion formation of aluminum, and can respond to the reinforcement member of various joinery.

  Further, it is possible to prevent the adverse effect caused by the difference in thermal expansion coefficient between steel and aluminum, reduce the risk of corrosion caused by the potential difference between steel and aluminum, and achieve a special effect.

In addition, the reinforcement technique by the reinforcement member of this invention is not only the reinforcement member arrange | positioned in the hollow part of a frame material or a brazing material, but the reinforcement member arrange | positioned in the glass front (panel opening) of a frame material or a brazing material, etc. It can also be employed for a reinforcing member disposed in a portion other than the hollow portion.
For example, in the above-described embodiment, the reinforcing members 61, 62, 63 made of steel such as steel or stainless steel can be constituted by reinforcing members made of aluminum.

(Other embodiments)
The reinforcing technique using the aluminum reinforcing member of the present invention can be applied not only to sliding windows but also to various window types such as open windows and sliding windows, but the application of the reinforcing technique is not limited to windows. However, it can be used for various building materials formed of an aluminum shape, and can be applied to, for example, a fire shutter device.

  As shown in FIG. 9, the shutter device 9 is disposed outside the sliding doors 2 and 3 in the sliding window and the like, and the chambers of the side walls 93 and 94 that also serve as the vertical frames 13 and 14 of the opening and closing windows. The guide rails 95 and 96 arranged on the outer side can open and close the end portions 972 of the slats constituting the shutter curtain 97.

  As shown in FIG. 10, the guide rail 95 has a guide groove 951 that opens in the inner circumferential direction, and the guide groove 951 of the guide rail 95 has a cross section that includes an outdoor wall portion 75 a and an outer peripheral wall portion 75 b. A substantially L-shaped aluminum reinforcing member 75 is disposed over substantially the entire length of the guide rail 95 in the longitudinal direction. The reinforcing member 75 reinforces the guide rail 95 by fixing the outer peripheral wall portion 75b to the bottom wall 951a of the guide groove 951 by a fixing means b such as a screw, so that the shutter device 9 Even if the guide rail 95 is melted, a hole communicating in the expected direction is prevented.

A groove-shaped guide rail auxiliary member 952 opening in the inner circumferential direction for guiding the end 972 of the slat 971 is disposed on the indoor side of the outdoor wall 75a of the reinforcing member 75 in the guide groove 951.
The indoor side wall 952a of the guide rail auxiliary member 952 extends in the inner circumferential direction, and the inner peripheral end of the outdoor wall portion 75a of the reinforcing member 75 and the inner peripheral end of the indoor side wall 952a of the guide rail auxiliary member 952 are provided. The heating expansion material f that expands by heating is arranged to face the part.

The thickness of the above-described aluminum reinforcing member of the present invention is not particularly limited, but the thickness necessary for firmly fixing the reinforcing member to the saddle member by a fixing means such as a screw is about 1.5 mm ( For a reinforcing member having a thickness of 1.5 mm and having a thickness of 1.5 mm, it is desirable that the thickness of the reinforcing member is 1.5 mm or more considering that the effect has been confirmed by experiments.
In this embodiment, the aluminum reinforcing member has a substantially U-shaped cross-section, but the cross-sectional shape is not limited to the U-shape, and is attached to the bottom of the glass front. The cross-sectional shape such as an L shape or a hollow shape is not limited as long as it includes a prospective surface for the purpose and a finding surface for suppressing penetration in the indoor / outdoor direction.

Furthermore, the distance between the brazing material and the aluminum reinforcing member is not limited to 1.0 mm. For example, if an interval of 1.0 mm or more can be provided, a further effect can be expected.
Moreover, in this embodiment, the reinforcement member which consists of aluminum materials is arrange | positioned and fixed with respect to the vertical shaft of a shoji, and the flame-shielding performance of the shoji as a whole is suppressed by suppressing the deformation of the relatively long vertical shaft. Although it is improved, the part where the reinforcing member is arranged and fixed is not limited to the vertical saddle of the shoji. It may be arranged and fixed in any part of a vertical frame such as a left and right vertical frame or a vertical frame. Furthermore, the flame barrier performance of the joinery can be improved even if it is disposed on any frame material or frame material that constitutes the window frame or the shoji.
