【発明の属する技術分野】
本発明は、建築物の内装を改修するにあたり、床下地の養生中に次工程の施工を行なうことできる脚体、足場および施工方法に関するものである。
【0002】
【従来技術】
近年、オフィスビル,学校,駅等の建築物での非住宅トイレ空間の改修において、床下地の工程では、モザイクタイル等の既存床上にまず、下地プライマーを塗付し、1日養生後、次に床下地材としてセルフレベリング材の流し込みを行なう。セルフレベリング材が硬化するまで、気温20℃、湿度65%の環境下で2日程度の養生、冬場の場合、3〜7日程度の養生を行ない、次工程の施工を行っている。
【0003】
【発明が解決しようとする課題】
従来では養生中は、次工程の施工ができないことにより、床下地の工程だけで4〜9日間かかり、工期が長くなっている上、トイレの使用ができない。
【0004】
特開平10−231165には、気温20℃,湿度65%の環境下で、3時間で硬化する組成物が開示されている。しかし、こういった超速硬性セルフレベリング材を使用しても、冬場では、超速硬性セルフレベリング材でも、12時間以上の養生が必要であるため、セルフレベリング材を流し込んだ当日には、次工程の施工はできない。
【0005】
非住宅トイレ空間の改修では、近年、周辺テナントへの影響を考慮して、トイレの使用頻度の少ない週末だけで工事を行なう要望があるが、その際、前述したように下地プライマー及びセルフレベリング材の養生時間が必要であるため、週末だけでの工事を行なうことができずに、要望に応えられないことがある。
このような場合、床下地材上に足場を設置すれば、前記足場上で次工程の作業を行なうことができると考えられるが、床下地材が硬化後に足場を取り除く際、足場と床下地材が密着し、簡単に足場を取り外すことができない。
【0006】
そこで本発明は、上記課題を解決するためになされたものであり、床下地材を施工した後、前記床下地上に足場を載置し、前記床下地材の養生中に前記足場上で次工程の作業を行なうことができ、さらに前記床下地材が硬化後、簡単に足場を回収することができる脚体、足場及び施工方法を提供することを目的とする。
【0007】
【課題を解決するための手段】
上記目的を達成するために請求項1記載の発明は、床下地材上で使用される脚体であって、脚部と板部とからなり、前記脚部が前記板部の各々の頂点に1本づつそれぞれ個別に着脱自在に取付けられていることを特徴とする脚体を提供する。
【0008】
本発明では、前記脚部が前記板部に対して着脱自在に取付けられているため、前記床下地材が硬化後、まず、前記板部を取り外した後、前記脚部を抜き取ることができ、簡単に足場の回収作業を行なうことができる。
即ち、床下地材が硬化した後、板部を取り外す際、板部と脚部が一体構造であると、脚部を真上に引き上げなければ板部が取り外せないが、本発明のような板部を脚部から取り外す構造をとることで、床下地材が硬化後、まず、板部を取り外し、次いで脚部を抜き取ることができ、容易に脚体の回収作業を行なうことができる。
また、床下地材が硬化した後、板部を取り外し、脚部を床下地材と面一で切断すれば、後工程の穴の補修作業を省略することができる。
【0009】
請求項2記載の発明は、請求項1記載の脚体において、脚部が板部側に向かって太くなるテーパー構造を有していることを特徴とする。
【0010】
この発明では、床下地材が硬化後、前記脚部を取り外す際に前記脚部がテーパー構造を有しているため、床下地材から簡単に抜き取ることができ、足場回収の作業性を向上することができる。
【0011】
請求項3記載の発明は、前記脚体の少なくとも2つ以上に板材を覆い被せ足場としたことを特徴とする。
【0012】
この発明では、足場としての広い面積が確保できるため、足場上での作業性を向上することができ、さらに板部と脚部から構成される脚体をコンパクトにすることができ、運搬性が向上する。
【0013】
請求項4記載の発明は、請求項3記載の足場において、前記板材の少なくとも端部と前記板部を固定することを特徴とする。
【0014】
この発明では、前記板材の端部のがたつきを軽減でき、さらに足場としての強度が増大する。
【0015】
請求項5記載の発明は、請求項1または2に記載の脚体と、該脚体同士を繋ぐ板材とからなる足場セットを提供する。
この発明では、あらかじめ汎用性のある大きさを足場セットとして容易しておくことで、特異な現場を除いて、養生中であってもすぐに次工程の施工ができる。
【0016】
請求項6記載の発明は、床下地材を施工し、次いで前記床下地材の養生中に作業を行なうために、請求項1ないし4のいずれかに記載の脚体を前記床下地材上に設置すると共に、請求項3または請求項4に記載の板材を前記脚体に載せ、前記床下地材が硬化した後、前記板材および前記脚体の板部を取り除き、次いで前記脚体の脚部を除去することを特徴とする。
【0017】
本発明では、前記脚部が前記板部に対して着脱自在に取付けられているため、前記床下地材が硬化後、まず、前記板部を取り外した後、前記脚部を抜き取ることができ、簡単に足場の回収作業を行なうことができる。
また、床下地材が硬化した後、板部を取り外す際、板部と脚部が一体構造であると、脚部を真上に引き上げなければ板部が取り外せないが、本発明のような板部を脚部から取り外す構造をとることで、床下地材が硬化後、まず、板部を取り外し、次いで脚部を抜き取ることができ、容易に脚体の回収作業を行なうことができる。
また、床下地材が硬化した後、板部を取り外し、脚部を床下地材と面一で切断すれば、後工程の穴の補修作業を省略することができる。
このように、この発明では、前記床下地材の養生中に次工程の作業を行なうことができる施工方法であるため、従来の養生後に次の工程に移る工法に比べて、トイレ改修工事期間を大幅に短縮することができる。
【0018】
【発明の実施の形態】
以下、図1から図10を基に本発明の一実施例を具体的に説明する。
本発明の脚体は少なくとも1本の板部1と脚部2で構成されるが、図1では脚部2を板部1の4隅にそれぞれ取付けた例を示す。
図2では、脚体を床下地材3上に載置した例を示す。脚部2は少なくとも部分的に床下地材3に埋没され、板部1を支持している。ここで、脚部と床下地材3の接触面積はできる限り少ない方が、脚部を取り除いた後の穴の補修作業が少なくてすむ。
また、脚部がテーパー構造を有していると、床下地材から簡単に抜き取ることができるので、作業性を向上することができる。
さらに、床下地材の乾燥の点から板部1は床下地材3と接触しない構造が好ましい。
床下地材3は、図示の例では、下地プライマーまたはセルフレベリング材であるが、モルタルまたはコンクリート等でも良く、特に限定されない。
【0019】
図3は、板部1から脚部2を取り外しできる脚体の例を示す断面図である。
板部1と脚部2は面ファスナまたは両面テープ等の着脱可能なテープ4で固定しているので板部1から脚部2を容易に取り外すことができる。
また、板部1と脚部2に板状磁石を接着すれば、さらに簡単に板部1と脚部2を着脱することができる。
また、床下地材3が硬化した後、板部1を取り外す際、板部1と脚部2が一体構造であると、脚部2が真上に引き上げなければ板部1が取り外せない。図3(b)のように板部1と脚部2を取り外すことができる構造であれば、床下地材3が硬化後、まず、板部1を取り外し、次いで脚部2を抜き取ることができ、容易に脚体の回収作業を行なうことができる。
【0020】
図4は、脚体の壁際の納まりを示す断面図である。
脚体の壁際の納まりについては、既存壁5に突き付けるのではなく、図4に示すように50mm程度空かして載置すれば、足場の施工後、巾木、壁下地、壁仕上げ等の壁の施工を行なうことができる。
【0021】
図5は、板部1と板材6の形状の一例について表した図である。
板部1及び板材6は、作業者が脚体または足場上で作業しやすいことから平面形状が好ましいが、特に板部1は、図5に限定されるものではなく、円形等でもよい。
【0022】
図6は脚体に板材を覆い被せて、使用した場合の足場構造の斜視図である。
脚体の少なくとも2つ以上に板材6を覆い被せれば、足場としての広い面積が確保できる。さらに板材6を使用する場合には、脚体をコンパクトにすることができ、脚体の運搬性が向上する。
また、板材6は1枚とは限らず、2枚重ねて使用すれば、足場としての強度が増大するので、複数枚使用してもよい。
また、脚体に板材6を覆い被せて使用する場合に、板材6の少なくとも端部と板部1をビス等で固定すれば、板材6の端部のがたつきを軽減でき、さらに足場としての強度が増大する。
【0023】
現場に応じて床面積及び出隅、入隅の数が異なるので、現場毎に板部1または板材6の形状は異なる。現場にて足場の加工を行なう場合、板部1及び板材6に加工性の良い合板、パーティクルボードを使用すれば、簡単に作業することができる。
一方、現場で加工場を確保できない場合や少しでも工期を短くしたい場合は、事前に現場に応じた形状で足場を用意すれば、床下地材3を流し込んだ直後に足場組みの作業を行なうことができ、工期短縮できる。
【0024】
また、汎用性のある大きさをあらかじめ足場セットとして容易しておくと、特異な現場を除いては、養生中であってもすぐに次工程の施工ができる。
【0025】
図7は、脚部2形状の一例について表した図である。
脚部2は、床下地材3が硬化した後、脚部2を取り外しやすいため、テーパー形状が好ましい。板部1における1枚あたりの脚部2の数量は、脚体が自立し、撓まない程度の間隔で設けられている限り、特に限定されず、1本でも良い。
脚部2の設置位置については、板部の各々の頂点に脚部2を設ければ脚体が安定し、脚体の端部に荷重がかかっても、脚体が倒れたりすることはない。
材質については、脚体を支持する必要があるため、例えば真鍮、金属のような剛性の高いものが望ましいが、特に限定されず、生産性の高い樹脂製でエポキシ、塩ビ、ノリル等を用いても良い。
また、脚部2の高さについては、市販されている床下地材3の最大施工厚みが20mm程度あるため、施工誤差を考慮して、少なくとも30〜40mm以上の高さは確保できる形状が望ましい。
【0026】
図8は、脚部が床下地材内に埋没したまま脚体を回収する例について表した図である。
これまでの例では、床下地材3が硬化した後、板部1を取り外し、脚部2を抜き取る施工手順であった。
これに対して、図8のように、床下地材3が硬化した後、板部1を取り外し、脚部2を床下地材3と面一で切断すれば、後工程の穴の補修作業を省略することができる。
なお、この場合は、脚部2に抜け防止部を設け、床下地材3から簡単に抜き取れないような構造が望ましい。
【0027】
図9(a)は、足場上に養生シートを敷き詰めた場合における足場構造の断面図である。図9(b)は、足場上に養生シートを敷き詰めた場合における足場構造の斜視図である。
床下地材3上に脚体を載置した後、ビニル系の養生シート7を既存壁5面と仮固定すれば、壁仕上げ材や配管の切断作業上、発生する粉じんが床下地材3表面に付着するのを防ぐことができる。
【0028】
図10は、本発明の標準的な施工手順を表した図である。
まず、床下地材3の施工がトイレの奥から入口に向かって行なわれる。
次に、図10(a)に示すように、トイレの入口から奥に向かって400mm×400mmの板部1と4本の脚部2で構成された脚体を900mm程度の間隔で設置していく。次に、図10(b)に示すように900mm×1800mmの板材6を脚体の上に覆い被せて載置し足場とし、各々の板部1と板材6をビス等で固定する。
(施工面積が狭く、脚体上で作業ができる場合は、板材を載置しなくてもよい。)
次に、図10(c)に示すように養生シート7を部分的に既存壁5と仮固定し、全面に敷きつめる。
以上の作業により、床下地材3の上方に足場が載置され、次工程の施工を行なうことができる。
その後、床下地材3が硬化した後、まずビスを取り外し、板材6を取り外し、続いて板部1を取り外す。そして、部分的に床下地材3内に埋没された脚部2を抜き取る。
最後に、脚部2が埋没していた床下地材3表面の凹部を補修用の速硬性パテで埋め戻し、長尺塩ビシートまたは塩ビタイル等の床仕上げ材の施工を行なう。
【0029】
【発明の効果】
本発明によれば、床下地材が養生中であっても、取り外し可能な脚部と板部とからなる脚体または足場を床下地材上に載置し、その上で次工程の施工ができるので、工期を短縮することができる。
また、本発明の脚体は床下地材が硬化した後に、板部を取り外し、その後脚部を抜き取ることができるので、簡単に足場の回収作業を行なうことができる。

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.
The leg of the present invention is composed of at least one plate portion 1 and leg portion 2, but FIG. 1 shows an example in which the leg portion 2 is attached to each of the four corners of the plate portion 1.
FIG. 2 shows an example in which the legs are placed on the floor base material 3. The leg portion 2 is at least partially embedded in the floor base material 3 and supports the plate portion 1. Here, if the contact area between the leg portion and the floor base material 3 is as small as possible, the repair work for the hole after removing the leg portion can be reduced.
In addition, when the leg portion has a tapered structure, it can be easily extracted from the floor base material, so that workability can be improved.
Furthermore, it is preferable that the plate portion 1 does not come into contact with the floor base material 3 from the viewpoint of drying the floor base material.
In the illustrated example, the floor base material 3 is a base primer or a self-leveling material, but may be mortar or concrete and is not particularly limited.
[0019]
FIG. 3 is a cross-sectional view showing an example of a leg body from which the leg portion 2 can be removed from the plate portion 1.
Since the plate portion 1 and the leg portion 2 are fixed by a removable tape 4 such as a hook-and-loop fastener or a double-sided tape, the leg portion 2 can be easily detached from the plate portion 1.
Further, if a plate magnet is bonded to the plate portion 1 and the leg portion 2, the plate portion 1 and the leg portion 2 can be attached and detached more easily.
Further, when the plate portion 1 is removed after the floor base material 3 is hardened, if the plate portion 1 and the leg portion 2 have an integral structure, the plate portion 1 cannot be removed unless the leg portion 2 is pulled up. If it is a structure which can remove the board part 1 and the leg part 2 like FIG.3 (b), after the floor base material 3 hardens | cures, the board part 1 can be removed first, and then the leg part 2 can be extracted. The leg can be easily collected.
[0020]
FIG. 4 is a cross-sectional view showing the fit of the leg body near the wall.
As for the fit of the legs near the wall, if it is placed about 50 mm away from the existing wall 5 as shown in FIG. Construction can be performed.
[0021]
FIG. 5 is a diagram illustrating an example of the shapes of the plate portion 1 and the plate material 6.
The plate portion 1 and the plate material 6 are preferably planar because the operator can easily work on the leg or the scaffold, but the plate portion 1 is not particularly limited to FIG. 5 and may be circular or the like.
[0022]
FIG. 6 is a perspective view of the scaffold structure when the leg is covered with a plate material.
If at least two of the legs are covered with the plate material 6, a large area as a scaffold can be secured. Furthermore, when using the board | plate material 6, a leg can be made compact and the transportability of a leg improves.
Moreover, since the board | plate material 6 is not restricted to 1 sheet | seat and the intensity | strength as a scaffold will increase if it uses two sheets, it may use several sheets.
In addition, when the leg material is covered with the plate material 6, if at least the end portion of the plate material 6 and the plate portion 1 are fixed with screws or the like, rattling of the end portion of the plate material 6 can be reduced, and as a scaffold The strength of the increases.
[0023]
Since the floor area, the number of exit corners, and the number of entrance corners differ depending on the site, the shape of the plate portion 1 or the plate material 6 differs for each site. When processing the scaffolding at the site, if a plywood or particle board having good processability is used for the plate portion 1 and the plate material 6, the work can be easily performed.
On the other hand, if it is not possible to secure a processing site at the site or if you want to shorten the construction period as much as possible, prepare the scaffold in a shape that suits the site in advance, and work on the scaffold assembly immediately after pouring the floor base material 3 The construction period can be shortened.
[0024]
In addition, if the size with versatility is facilitated in advance as a scaffold set, the next process can be performed immediately even during curing, except in specific sites.
[0025]
FIG. 7 is a diagram illustrating an example of the shape of the leg 2.
The leg 2 is preferably tapered since the leg 2 is easy to remove after the floor base material 3 is cured. The number of the leg portions 2 per sheet in the plate portion 1 is not particularly limited as long as the legs are provided at intervals such that the legs are self-supporting and do not bend.
About the installation position of the leg part 2, if the leg part 2 is provided in each vertex of a board part, a leg will be stabilized, and even if a load is applied to the edge part of a leg, a leg will not fall down. .
As for the material, since it is necessary to support the leg, for example, a material having high rigidity such as brass or metal is desirable, but it is not particularly limited, and is made of highly productive resin using epoxy, vinyl chloride, noryl, etc. Also good.
Moreover, about the height of the leg part 2, since the maximum construction thickness of the floor base material 3 marketed is about 20 mm, the shape which can ensure the height of at least 30-40 mm or more is considered in consideration of a construction error. .
[0026]
FIG. 8 is a diagram illustrating an example in which the leg is collected while the leg is buried in the floor base material.
In the example so far, after the floor base material 3 hardened | cured, it was the construction procedure which removes the board part 1 and extracts the leg part 2. FIG.
On the other hand, as shown in FIG. 8, after the floor base material 3 is cured, if the plate portion 1 is removed and the leg portion 2 is cut flush with the floor base material 3, the hole repair work in the subsequent process is performed. Can be omitted.
In this case, it is desirable to provide a structure in which a leg prevention part is provided in the leg part 2 so that it cannot be easily removed from the floor base material 3.
[0027]
Fig.9 (a) is sectional drawing of a scaffold structure at the time of spreading a curing sheet on a scaffold. FIG. 9B is a perspective view of the scaffold structure when a curing sheet is spread on the scaffold.
After placing the legs on the floor base material 3, if the vinyl-based curing sheet 7 is temporarily fixed to the existing wall 5 surface, the generated dust will be generated on the surface of the floor base material 3 when cutting the wall finishing material and piping. Can be prevented from adhering to.
[0028]
FIG. 10 is a diagram showing a standard construction procedure of the present invention.
First, the construction of the floor base material 3 is performed from the back of the toilet toward the entrance.
Next, as shown in FIG. 10 (a), a leg body composed of a plate portion 1 of 400 mm × 400 mm and four leg portions 2 from the entrance of the toilet to the back is installed at intervals of about 900 mm. Go. Next, as shown in FIG. 10 (b), a plate material 6 of 900 mm × 1800 mm is covered and placed on the legs to form a scaffold, and each plate portion 1 and the plate material 6 are fixed with screws or the like.
(If the construction area is small and work can be performed on the legs, it is not necessary to place the plate.)
Next, as shown in FIG.10 (c), the curing sheet 7 is partially temporarily fixed with the existing wall 5, and it spreads over the whole surface.
With the above operation, the scaffold is placed above the floor base material 3, and the next process can be performed.
Thereafter, after the floor base material 3 is cured, the screws are first removed, the plate material 6 is removed, and then the plate portion 1 is removed. And the leg part 2 partially embedded in the floor base material 3 is extracted.
Finally, the concave portion on the surface of the floor base material 3 in which the legs 2 are buried is backfilled with a fast-curing putty for repairing, and a floor finishing material such as a long PVC sheet or a PVC tile is applied.
