Description

【0001】
【発明の属する技術分野】
本発明は、木造建築の床または屋根に使用されるALCパネルに関するものである。
【0002】
【従来の技術】
一般に、木造建築の床または屋根にALCパネルを敷設するときは、図5および図6に示すように、隣接するALCパネル10の小口面同士を当接させ、パネルの少なくとも短辺小口両端部を梁5に架けた状態で敷き詰める。
また、柱3、間柱8、筋かい9とパネル10とが干渉するときは、柱等を避けるために、パネルの干渉する部位に切り欠き2を設けてから施工している。
例えば、図5に示すように、木造建築に通常使用される柱の幅T=120mm角の柱3の周囲においては、その柱3の幅Tの1/2とクリアランスC(柱3とパネル10との隙間)とを加えた部位をALCパネル10から切り欠いている。
このとき、この切り欠き2の部位にパネルの長さ方向に埋設された補強筋4(主筋4a)または幅方向に埋設された(副筋4b)の一部が切断されて、パネルに切り欠き2が設けられることになる。
【0003】
また、工場生産されるALCパネル10の長さ寸法は規定されている一方で、木造建築は梁5などの下地材寸法あるいは施工の誤差があるため、パネル10の短辺小口両端部を架ける梁5の間隔Z(図6参照)にバラツキが生じ易い。
このため、床パネル10を敷設する実際の施工現場では、図7に示すように、隣接するパネル同士の短辺小口の突き合わせ位置7が梁5の中心からずれて、どちらか一方のパネルの端部の梁5への架かり代が小さくなってしまうことがある。
【0004】
このとき、梁5の中心からずれている長いパネル側の端部を長さ調整のために短辺小口面と平行に切除すると、端部に埋設されていた副筋4bも同時に除去されてしまう。すると、副筋4bが埋設されていないパネル端部が梁5に架けられるという危険な状態が発生してしまう。このため、長さ調整のためにパネル小口面端部を切断することはできない。
そこで、通常、この問題を解決するために、図7に示すように、架かり代の小さいパネル下部に、梁と平行な受け材6を追加して設置することによりパネル10を支えている。
【0005】
【発明が解決しようとする課題】
通常、柱3等との干渉を避けるために、埋設された補強筋4の主筋4aまたは副筋4bの一部が切断されて切り欠き2が形成されている。このため、パネル10の長さ方向に埋設される主筋4aの場合、その一部が切断されてもパネル全体の曲げ強度が低下しないように、余分の主筋4aを予め埋設させておくことになる。
しかし、この方法は切断される主筋4aの位置及び本数を予測することが困難であるとともに、製造コストが増加するという問題点があった。
さらに、切断されて露出した主筋4aの断面に錆が発生する問題もあった。
【0006】
また、短辺小口端部の梁5への架かり代の小さいパネル10が発生して、梁5の一カ所でも受け材6を追加すると、その調整作業が次々と隣接する梁5へと順送りされていく。そして、床全体の梁部において受け材6の設定が必要となり、施工効率を著しく低下させていた。
そこで、本発明の目的は上記問題点を解決して 、木造建築の床施工においてパネルに切り欠きを設けても、余分な主筋をパネルに予め埋設させておく必要がなく、かつ、施工効率も低下させないALCパネルを提供することにある。
【0007】
【課題を解決するための手段】
木造建築の床または屋根用のALCパネルにおいて、
そのALCパネルの長辺小口面から50mm〜100mmまでの位置、および短辺小口面から20mm〜30mmまでの位置を補強筋が埋設されていない無筋部分とし、その内側に補強筋を埋設したALCパネルを採用した。
【0008】
【発明の実施の形態】
以下、本発明の実施形態を図1〜4に基づいて説明する。なお、符号は従来例と同一のものは同一符号を付した。
図1は本発明の実施形態を示すALCパネル1の斜視図、図2はそのパネルの平面図、図3はそのパネルの断面図、図4は切り欠きが設けられたパネルの平面図、をそれぞれ示す。
本発明は、木造建築の床または屋根用のALCパネルの周縁部を無筋部分としたパネルである。
すなわち、図1、図2及び図3に示すように、本発明のパネル1は、その長辺小口面から50mm〜100mmまでの位置Y、および短辺小口面から20mm〜30mmまでの位置Xは補強筋4が埋設されていない無筋部分であり、その内側に補強筋4が埋設されているALCパネルである。
【0009】
これにより図4に示すように、通常の木造建築の柱3、間柱8、筋かい9とパネル1とが干渉する部位に切り欠き2(2a、2b、2c、2d)を設けても、埋設された補強筋4(主筋4a及び副筋4b)が切断されることがなくなる。
また、補強筋4のうち特に副筋4bがパネル1の短辺小口面から20mm〜30mmまでの位置Xの内側に埋設されているため、隣接パネル1との突き合わせ位置7が梁5の中心からずれても、パネル1の短辺小口面から内側に15mm以下を切除して長さ調整をすることにより突き合わせ位置7を調整することが可能となる。これにより、従来例の図7に示す受け材6を梁に追加して設置する必要がなくなる。
【0010】
また、ALCパネル1は、パネルの厚さが100mm以下になると、要求されるパネル曲げ強度が小さくなるため埋設される補強筋4の数も減少する。
このように、1本の補強筋4の切断がパネル曲げ強度へ与える影響が大きくなる厚さ100mm以下のパネルにとっては、本発明の効果が一層発揮されるようになり、より好ましい。
そして、ALCパネル1の厚さが80mm以下であって、主筋4aと副筋4bとが格子状に溶接固定された格子状補強鉄筋が1枚のみ埋設されたパネルにおいては、同様の理由により、さらに本発明の効果が発揮されるようになり望ましい。
また、切り欠きを設けるときに鉄筋に比べて長さ方向の切断が非常に困難なラス網またはメッシュ筋が補強筋4として埋設されている厚さ80mm以下のパネルであると、切り欠き加工の作業性が著しく向上する。
【0011】
また、ALCパネル1の長辺小口面から内側へ60mm〜90mmまでの位置の内側に補強鉄筋4が埋設されていると、通常の柱3の一辺が105mm〜135mmである木造建築に対して、柱の幅Tの1/2=52〜68mmとクリアランスC(10mm〜20mm)とを加算した寸法がパネル1の無筋部分と一致するようになる。
これにより、柱3等を避けるために切り欠き2の加工をしても、切り欠き加工後のパネル外周縁部に沿って補強筋4が配設されることとなり、また、補強筋4(副筋4b)が十分な架かり代で梁5に架かるようになりパネル面へ垂直方向に働く積載荷重等への信頼性が向上する。
【0012】
主筋4aと副筋4bとを格子状に溶接固定した格子状補強鉄筋4が2枚連結されたカゴ状補強鉄筋4が埋設されているALCパネルであると、切り欠き加工のときに、複数本の鉄筋を切断する必要がなくなるため切断用の刃の寿命が延びるとともに作業性も著しく向上する。
なお、床用ALCパネルの施工で本発明を説明をしたが、屋根用パネルの施工においても同様の効果が得られる。
【0013】
【実施例】
図1、図2及び図3に示すように、ALCパネル1(長さ1820mm、幅606mm、厚さ80mm)の長辺小口面から85mmまでの位置Y、および短辺小口面から25mmまでの位置Xを補強鉄筋4が埋設されていない無筋部分として、その内側に補強鉄筋4が埋設されたパネルを製造した。
このとき補強鉄筋4は、直径5mmの主筋4a(4本)と副筋4b(7本)とを格子状に溶接固定した格子状補強鉄筋を2枚連結させたカゴ状補強鉄筋とした。
【0014】
主な部材の断面寸法が、次に示すような一般的木造建築に床パネル1を敷設した。
柱3   :120mm×120mm  間柱8 :105mm×35mm
筋かい9 :105mm×45mm
梁5   :幅120mm×せい210mm
梁の間隔Z:約910mm
そして、図4に示すように、柱3、間柱8および筋かい9を避けるためにALCパネル1の一部に切り欠き2a、2b、2c、2dを設けた。
ALCパネル1と柱3、間柱8、筋かい9とのクリアランスが20mmになるように、それぞれ次に示す寸法(パネル幅方向への寸法×パネル長さ方向への寸法)で、ALCパネル1を切り欠いた。
切り欠き2a(柱3)       : 80mm×80mm
切り欠き2b(柱3)            : 80mm×160mm
切り欠き2c(間柱8)          : 80mm×75mm
切り欠き2d(柱3+筋かい9) : 80mm×220mm
【0015】
また、実際の梁間隔は、部材寸法及び施工誤差により905〜915mmとバラツキがあったため、隣接するALCパネル1の短辺小口での突き合わせ位置7が、梁3の中心からずれる不具合を生じていた。
そこで、ALCパネル1の短辺小口端部を15mm以下(両端部をあわせて30mm以下)切断することにより長さ調整をして、突き合わせ位置7を梁3の中心に一致た。これにより、すべてのALCパネル1の端部において、梁への十分に架かり代を確保してALCパネル敷設をすることができた。
【0016】
これらの結果、ALCパネル1内部の補強筋4は1本も切断されることがなく、かつ、梁5に受け材6を追加することもなく、木造建築の柱3、間柱9、筋かい9を避けながらALCパネル1を床に敷設することができた。
【0017】
【発明の効果】
本発明によれば、木造建築の床または屋根にALCパネルを敷設するときに、柱、間柱、筋かい等を避けるためにパネルの一部を切り欠いても、そのパネルの曲げ強度を減少させない。
さらに、切り欠きの加工時に埋設された補強筋を切断する必要がないため、切断工具の寿命を延ばすとともに作業性を向上させる。
また、施工時における補強筋の切断を予測して、余分な補強筋を予め埋設しておく必要もなくなる。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an ALC panel used for a wooden building floor or roof.
[0002]
[Prior art]
Generally, when laying an ALC panel on the floor or roof of a wooden building, as shown in FIGS. 5 and 6, the edge faces of adjacent ALC panels 10 are brought into contact with each other, and at least both short edge edges of the panel are joined. Spread it over the beam 5.
When the columns 3, the studs 8, the struts 9 and the panel 10 interfere with each other, the notch 2 is provided in a portion where the panels interfere with each other in order to avoid the columns and the like.
For example, as shown in FIG. 5, around a pillar 3 having a width T = 120 mm square, which is generally used for wooden construction, about 1/2 of the width T of the pillar 3 and a clearance C (the pillar 3 and the panel 10). (A gap between the ALC panel 10) is cut out from the ALC panel 10.
At this time, a part of the reinforcing bar 4 (main bar 4a) buried in the length direction of the panel or a part of the reinforcing bar 4 (sub bar 4b) buried in the width direction is cut at the portion of the notch 2, and the panel is cut out. 2 will be provided.
[0003]
In addition, while the length of the ALC panel 10 produced in the factory is specified, the wooden building has a base material dimension such as the beam 5 or an error in the construction. Variations easily occur in the interval Z (see FIG. 6) of No. 5.
For this reason, at the actual construction site where the floor panel 10 is laid, as shown in FIG. 7, the abutting position 7 of the short side edge of the adjacent panel is shifted from the center of the beam 5, and the end of one of the panels In some cases, the margin of the part to be connected to the beam 5 may be reduced.
[0004]
At this time, if the long panel-side end shifted from the center of the beam 5 is cut in parallel with the short side edge for the length adjustment, the auxiliary streak 4b buried at the end is also removed at the same time. . Then, a dangerous state occurs in which the end of the panel where the sub-reinforcement 4b is not buried is hung on the beam 5. For this reason, it is not possible to cut the edge of the panel forefront to adjust the length.
Therefore, in order to solve this problem, as shown in FIG. 7, a panel 10 is supported by additionally installing a receiving member 6 parallel to the beam at the lower part of the panel having a small margin.
[0005]
[Problems to be solved by the invention]
Usually, in order to avoid interference with the pillar 3 and the like, the notch 2 is formed by cutting a part of the main reinforcement 4a or the auxiliary reinforcement 4b of the embedded reinforcement 4. For this reason, in the case of the main reinforcement 4a buried in the length direction of the panel 10, an extra main reinforcement 4a is buried in advance so that the bending strength of the entire panel does not decrease even if a part of the main reinforcement 4a is cut. .
However, this method has problems that it is difficult to predict the position and the number of the main bars 4a to be cut, and the manufacturing cost increases.
Further, there is a problem that rust is generated on the cross section of the main bar 4a that is cut and exposed.
[0006]
In addition, when a panel 10 having a small margin for bridging the beam 5 at the edge of the short side edge is generated and the receiving material 6 is added at one place of the beam 5, the adjustment work is sequentially sent to the adjacent beam 5 one after another. Will be done. Then, it is necessary to set the receiving material 6 in the beam portion of the entire floor, and the construction efficiency has been significantly reduced.
Therefore, an object of the present invention is to solve the above-mentioned problems, even if a notch is provided in a panel in the floor construction of a wooden building, it is not necessary to bury an extra main reinforcement in the panel in advance, and the construction efficiency is improved. An object of the present invention is to provide an ALC panel that does not lower the ALC panel.
[0007]
[Means for Solving the Problems]
For ALC panels for wooden floors or roofs,
An ALC panel in which a position from 50 mm to 100 mm from the long edge of the ALC panel and a position from 20 mm to 30 mm from the short edge of the ALC panel are unreinforced portions in which no reinforcing bars are embedded, and reinforcing bars are embedded inside the portion. Panel was adopted.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to FIGS. In addition, the same code | symbol was attached | subjected to the code | symbol same as the conventional example.
FIG. 1 is a perspective view of an ALC panel 1 showing an embodiment of the present invention, FIG. 2 is a plan view of the panel, FIG. 3 is a cross-sectional view of the panel, and FIG. 4 is a plan view of a panel provided with notches. Shown respectively.
The present invention is a panel in which the periphery of an ALC panel for a floor or a roof of a wooden building has a straight portion.
That is, as shown in FIGS. 1, 2 and 3, the panel 1 of the present invention has a position Y from 50 mm to 100 mm from the long edge and a position X from 20 mm to 30 mm from the short edge. This is an ALC panel in which the reinforcing bars 4 are buried without reinforcing bars 4 buried therein.
[0009]
Thereby, as shown in FIG. 4, even if the notch 2 (2a, 2b, 2c, 2d) is provided in a portion where the panel 1, the pillar 3, the stud 8, the bracing 9, and the panel 1 of the ordinary wooden building interfere, The reinforcing bars 4 (the main bars 4a and the sub bars 4b) that have been cut are not cut off.
In addition, since the auxiliary reinforcing bar 4b of the reinforcing bar 4 is particularly buried inside the position X from 20 mm to 30 mm from the short edge of the panel 1, the abutting position 7 with the adjacent panel 1 is positioned from the center of the beam 5. Even if it is displaced, it is possible to adjust the butting position 7 by trimming 15 mm or less inward from the short side edge of the panel 1 and adjusting the length. This eliminates the need to additionally install the receiving member 6 shown in FIG.
[0010]
When the thickness of the ALC panel 1 is 100 mm or less, the required panel bending strength is reduced, so that the number of embedded reinforcing bars 4 is also reduced.
As described above, for a panel having a thickness of 100 mm or less, in which the influence of the cutting of one reinforcing bar 4 on the panel bending strength is large, the effect of the present invention is further exerted, which is more preferable.
For a panel in which the thickness of the ALC panel 1 is 80 mm or less and in which only one reinforcing reinforcing bar in which the main reinforcing bar 4a and the auxiliary reinforcing bar 4b are welded and fixed in a grid is buried, for the same reason, Further, the effects of the present invention are exhibited, which is desirable.
Further, when a notch is provided on a panel having a thickness of 80 mm or less in which a lath net or a mesh bar, which is extremely difficult to cut in the length direction as compared with a reinforcing bar, is buried as the reinforcing bar 4, the cutout process is performed. Workability is significantly improved.
[0011]
In addition, when the reinforcing steel bar 4 is buried inside the position from 60 mm to 90 mm inward from the long edge of the ALC panel 1, for a wooden building in which one side of the ordinary pillar 3 is 105 mm to 135 mm, The dimension obtained by adding 1 / of the width T of the column = 52 to 68 mm and the clearance C (10 to 20 mm) matches the straight portion of the panel 1.
Thereby, even if the notch 2 is processed to avoid the pillar 3 and the like, the reinforcing bar 4 is provided along the outer peripheral edge of the panel after the notch processing, and the reinforcing bar 4 ( The streaks 4b) are bridged on the beams 5 with a sufficient bridging margin, and the reliability with respect to the loading load acting on the panel surface in the vertical direction is improved.
[0012]
When an ALC panel in which a cage reinforcing bar 4 in which two main reinforcing bars 4a and a main reinforcing bar 4b are welded and fixed in a grid shape and two cage-shaped reinforcing bars 4 are connected is embedded, a plurality of reinforcing bars 4 Since it is not necessary to cut the reinforcing bar, the life of the cutting blade is extended and workability is remarkably improved.
Although the present invention has been described with reference to the construction of ALC panels for floors, similar effects can be obtained in construction of roof panels.
[0013]
【Example】
As shown in FIGS. 1, 2 and 3, the position Y of the ALC panel 1 (length: 1820 mm, width: 606 mm, thickness: 80 mm) from the long side small face to 85 mm, and the position from the short side small face to 25 mm A panel in which the reinforcing steel 4 was buried inside X was made as a straight part where the reinforcing steel 4 was not buried.
At this time, the reinforcing reinforcing bar 4 was a cage reinforcing bar in which two grid-shaped reinforcing bars in which a main bar 4a (four bars) and a sub-bar 4b (seven bars) each having a diameter of 5 mm were welded and fixed in a grid shape.
[0014]
The floor panel 1 was laid on a general wooden building whose main members had the following cross-sectional dimensions.
Pillar 3: 120mm x 120mm Stud 8: 105mm x 35mm
Bracing 9: 105mm x 45mm
Beam 5: width 120mm x 210mm
Beam spacing Z: about 910 mm
Then, as shown in FIG. 4, notches 2a, 2b, 2c and 2d were provided in a part of the ALC panel 1 in order to avoid the pillar 3, the stud 8 and the bracing 9.
The ALC panel 1 is dimensioned as follows (dimension in the panel width direction x dimension in the panel length direction) so that the clearance between the ALC panel 1 and the pillar 3, the stud 8, and the bracing 9 is 20 mm. Notched.
Notch 2a (pillar 3): 80 mm x 80 mm
Notch 2b (pillar 3): 80 mm x 160 mm
Notch 2c (Stud 8): 80 mm x 75 mm
Notch 2d (pillar 3 + bracing 9): 80 mm x 220 mm
[0015]
In addition, since the actual beam interval varied from 905 to 915 mm due to the member size and the construction error, the abutting position 7 at the short side edge of the adjacent ALC panel 1 was deviated from the center of the beam 3. .
Then, the short edge of the short side of the ALC panel 1 was cut by 15 mm or less (30 mm or less in total at both ends), the length was adjusted, and the butting position 7 coincided with the center of the beam 3. As a result, the ALC panels could be laid at the ends of all the ALC panels 1 while securing a sufficient margin for the beams.
[0016]
As a result, the reinforcing bars 4 inside the ALC panel 1 are not cut at all, and the supporting members 6 are not added to the beams 5, and the pillars 3, the studs 9, and the braces 9 of the wooden building are used. The ALC panel 1 was able to be laid on the floor while avoiding.
[0017]
【The invention's effect】
According to the present invention, when laying an ALC panel on the floor or roof of a wooden building, even if a part of the panel is cut out to avoid columns, studs, braces, etc., the bending strength of the panel is not reduced. .
Further, since it is not necessary to cut the reinforcing bars buried when the notch is machined, the life of the cutting tool is extended and workability is improved.
Further, it is not necessary to predict the cutting of the reinforcing bars at the time of construction and bury the extra reinforcing bars in advance.
