【発明の詳細な説明】
本発明は、建物のコンクリート階段の仕上げ工法に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a finishing method for concrete stairs in a building.
建物の外部階段にはコンクリート製のものも多く、当然
のことながら型枠を組んでコンクリートを打設して施工
する。Many of the external staircases of buildings are made of concrete, and naturally they are constructed by building formwork and pouring concrete.
第３図〜第５図はこのようなコンクリート階段を示すも
ので、図中１は蹴込み、２は踏面で、壁３との境界部に
は一段深く形成した排水側溝４を設け、また踏面２の先
端に磁器タイル類のノンスリップ材５を埋設している。Figures 3 to 5 show such concrete stairs. In the figures, 1 is a riser, 2 is a tread, and the boundary with the wall 3 is provided with a drainage gutter 4 that is deeper than the tread. A non-slip material 5 made of porcelain tiles is buried at the tip of the tile.
かかるコンクリート階段は、施工の一例として階段用の
コンクリートを打設し、充分な硬化を待って、前記ノン
スリップ材５を踏面２上にモルタルで貼付け、そのあと
蹴込み１及び踏面２をモルタルで仕上げていた。As an example of construction, such concrete stairs are constructed by pouring concrete for stairs, waiting for sufficient hardening, pasting the non-slip material 5 on the treads 2 with mortar, and then finishing the risers 1 and treads 2 with mortar. was.
特に外部階段の場合は、直射日光の他に風雨にさらされ
る時間が多く、時間の経過とともに仕上げられたモルタ
ル等にクラックが発生し、それより下地のコンクリート
面からのモルタル及びノンスリップ材の剥離が生じやす
い。Particularly in the case of external stairs, they are often exposed to wind and rain in addition to direct sunlight, and over time cracks occur in the finished mortar, etc., and the mortar and non-slip material peel off from the underlying concrete surface. Easy to occur.
また、コンクリート打設後、墨出しを行ない、下地塗り
をしてからノンスリップ材を配置し、また仕上げモルタ
ルを塗るなど工程数が多い。しかも仕上げの日数に加え
て、各仕上げ工程間には相当の乾燥期間を要し、工期が
長くなる。In addition, after concrete is poured, there are many steps such as marking, applying a base coat, placing non-slip material, and applying finishing mortar. Moreover, in addition to the number of days required for finishing, a considerable drying period is required between each finishing process, which lengthens the construction period.
当然のことながら工事中の階段は通行止めとなるため、
作業動線が制限されその期間が長いと建築工事全体の作
業性も著しく低下する。Naturally, the stairs will be closed to traffic during construction.
If the work flow line is restricted and the period is long, the workability of the entire construction work will be significantly reduced.
本発明の目的は前記従来例の不都合を解消し、施工の簡
略化ひいては工期、工費の削減を実現できるコンクリー
ト階段の仕上げ工法を提供することにある。An object of the present invention is to provide a finishing method for concrete stairs that eliminates the disadvantages of the conventional example and can simplify the construction and reduce the construction period and cost.
本発明は前記目的を達成するため、コンクリート打設後
蹴込み用型枠がセットされている段階で、ノンスリップ
材を下面に両面接着テープで貼付けた左官定木を、該型
枠の」二端と平行にセットし、また、踏面コンクリート
の金鏝押えを行いコンクリート硬化後に蹴込み用型枠及
び左官定木を取外すことを要旨とするものである。In order to achieve the above-mentioned object, the present invention installs a plastering board with a non-slip material pasted to the lower surface using double-sided adhesive tape at the two ends of the formwork at the stage when the riser formwork is set after concrete is poured. The gist of this project is to set the concrete in parallel with the tread surface, press down the tread concrete with a metal trowel, and remove the riser formwork and plastering timber after the concrete has hardened.
〔作用］
本発明によれば、コンクリート打設後これが硬化する前
に左官定木を介してノンスリップ材を一挙にセットでき
、コンクリート硬化後は該ノンスリップ材が自動的に埋
設されていることになる。[Function] According to the present invention, the non-slip material can be set all at once through the plastering timber after concrete is poured and before it hardens, and the non-slip material is automatically buried after the concrete hardens. .
このように、コンクリート打設後すぐに階段の仕上げに
着手でき、犬１↑１な工期の短縮となる。In this way, finishing of the stairs can be started immediately after concrete is poured, which shortens the construction period by 1↑1.
以下、図面について本発明の実施例を詳細に説明する。 Embodiments of the present invention will be described in detail below with reference to the drawings.
第１図は本発明のコンクリート階段の１実施例を示す縦
断側面図で、図中６は合板製の蹴込み用型枠、７は該型
枠６の固定用桟木である。FIG. 1 is a longitudinal sectional side view showing one embodiment of the concrete staircase of the present invention, in which 6 is a plywood riser form, and 7 is a crosspiece for fixing the form 6.
この蹴込み用型枠６はその上端を踏面２の仕上げ天端に
カットし、また下端に下方の桟木７とともにテーパー状
に切欠き８を設けた。The riser form 6 has its upper end cut to the finished top end of the tread 2, and its lower end is provided with a tapered notch 8 together with the lower crosspiece 7.
このような型枠６は、図示しない側桁用型枠及び底部型
枠などと組合わさって階段用コンクリート打設のための
枠組となる。Such formwork 6 is combined with side girder formwork and bottom formwork (not shown) to form a framework for pouring concrete for stairs.
第２図は前記枠組の一部材である側溝ヌスミ板１０の配
設状態を示したものであり、該ヌスミ板１゜は解体を容
易にするため端部にテーパー１０ａをつけた。また、こ
のヌスミ板１０は図示は省略するが、コンクリート打設
時のエアー抜き穴を付ける。FIG. 2 shows the arrangement of the side gutter bulging board 10, which is a member of the framework, and the lining board 1° has a tapered end 10a to facilitate disassembly. Further, although not shown in the drawings, this hollow board 10 is provided with air vent holes during concrete pouring.
階段コンクリート１３は最下段から最上段まで−・度に
打上げるものとし、踏面２のコンクリート吹出しを防止
するため合板ベニヤ等による仮蓋９をしておく。Stair concrete 13 is to be launched from the bottom step to the top step in steps of -1, and a temporary cover 9 made of plywood veneer or the like is provided to prevent the concrete from blowing out from the tread 2.
そして、最上段までコンクリート１３が打上った段階で
、前記仮Ｍ９を撤去する。Then, when the concrete 13 has been poured to the top level, the temporary M9 is removed.
このようにしてから、下面に両面接着テープ１１を介し
てノンスリップ材５を貼付けた左官定木１２を前記蹴込
み用型枠６の上端と平行にセットするが、この段階では
コンクリート１３は未硬化の状態であり、ノンスリップ
材５は表面を残してコンクリート１３中に没入する。After doing this, the plastering board 12 with the non-slip material 5 attached to the lower surface via the double-sided adhesive tape 11 is set parallel to the upper end of the riser form 6, but at this stage the concrete 13 is uncured. In this state, the non-slip material 5 is immersed into the concrete 13 leaving the surface intact.
なお、ノンスリップ材５の表面にある左官定木１２は該
ノンスリップ材５０表面にコンクリートが付着するのを
防止するとともにノンスリップ材５を乱れないで規定位
置に固定する役割を有する。The plastering wood 12 on the surface of the non-slip material 5 has the role of preventing concrete from adhering to the surface of the non-slip material 50 and fixing the non-slip material 5 at a specified position without disturbing it.
同時に踏面２の金鏝押えを行なうが、左官定木１２を利
用してこの作業ができる。この金鏝によるコンクリート

欠き８は、金鏝が入りやすくするのに役立つ。また、踏
面２には第１図矢印のごとく水勾配をつける。At the same time, the tread 2 is pressed down with a metal trowel, and this work can be done using the plastering board 12. When pressing concrete with this trowel, the notch 8 at the lower end of the riser form 6 serves to facilitate the insertion of the trowel. Additionally, the tread 2 is provided with a water gradient as shown by the arrow in Figure 1.
コンクリート１３の硬化後に、ノンスリップ材５は埋設
された状態で、該コンクリート１３で拘束されるので、
これを残して左官定木１２を外し、また蹴込み用型枠６

放しの仕上げとする。After the concrete 13 hardens, the non-slip material 5 is buried and restrained by the concrete 13.
Leaving this in place, remove the plastering tree 12, and then remove the formwork 6 for the riser.
Remove the mold. The riser 1 formed by this formwork 6 has an exposed finish.
以上述べたように本発明のコンクリート階段の仕上げ工
法は、コンクリート打設直後から仕上げ作業に入れるも
のであり、大幅な工程の短縮と工費の削減が図かれる。As described above, the concrete staircase finishing method of the present invention allows the finishing work to begin immediately after concrete is poured, thereby significantly shortening the process and reducing construction costs.
また、仕上げ内容としてもモルタル工法によるものでは
ないので、モルタル及びノンスリップ材の剥離を将来起
こすこともなく、良好なものが得られる。Furthermore, since the finish is not based on the mortar method, a good finish can be obtained without causing peeling of the mortar and non-slip material in the future.
