A method of finishing it smooth using etc.
４） 最近では、打設した下地材の硬化が完了する前に
ＳＬ材を流し延べる工法が提案されている。4) Recently, a construction method has been proposed in which SL material is poured before the hardening of the cast base material is completed.

昭６０−２２３５７３号）などがある。4-1) After pouring concrete, a cement-based slurry is poured and hardened while a slight amount of breathing water remains on the concrete surface (Japanese Unexamined Patent Publication No. 1983-
155434) and; 4-2) After placing concrete, breathing water is forcibly removed when the concrete has finished settling, and then SL material is poured onto the concrete surface (Japanese Patent Application Laid-Open No. 60-223573). )and so on.
１）の方法は、下地材を打設し、硬化養生してからセメ

練した左官技術を必要とするなどの難点がある。Method 1) requires two discontinuous steps, as the base material is poured, cured, and then finished with cement mortar.
The required construction period will be longer. There are also disadvantages in that poor adhesion may occur on discontinuous surfaces, and that skilled plastering techniques are required to obtain surface smoothness.

、それでも接着不良を生じやすいという難点がある。Method 3) also requires two discontinuous steps to cast the base material and pour the SL material after hardening and curing, resulting in a long construction period. This requires cleaning the surface of the base material, applying a primer, etc., and even then, there is a drawback that poor adhesion is likely to occur.

着性が充分でないという難点がある。In methods such as 4-1) or 4-2), in which SL material is poured before the hardening of the poured concrete is completed, it is necessary to check the water drainage of the concrete or force breathing water. Even if the concrete is simply removed and the SL material is poured, there is a problem that the integration of the concrete and the SL material is insufficient and the adhesion is not sufficient.
本発明の目的は、下地材の打設とＳｔ、材の流し延べを
連続して行い施工時間を短縮すると共に下地材とＳＬ材
との接着面の強度を確保し、容易に床の平滑面を得るこ
とができる床仕上げ工法を提供することにある。The purpose of the present invention is to shorten the construction time by continuously placing the base material and pouring the St and material, and to ensure the strength of the bonding surface between the base material and the SL material, so that it can be easily applied to the smooth surface of the floor. Our goal is to provide a floor finishing method that can achieve the desired results.

グ材の施工方法」を要旨とする。In other words, the present invention relates to a self-leveling method in which a cement-based mortar or concrete is used as a base material, and a self-leveling material is poured over the base material to form a smooth floor surface, in which the base material is poured and leveled. Then, before the hardening of the base material is completed, the surface of the base material is roughened and the self-leveling material is poured on."
以下、本発明の方法について説明する。The method of the present invention will be explained below.

ィミックストコンクリートなどを含む。The method of the present invention targets floors of structures in which cement mortar or concrete is cast as a base material, and examples of concrete include lightweight concrete, crushed stone concrete, watertight concrete, pre-punk concrete, ready-mixed concrete, and the like.
下地材打設後の均平化は、通常トンボや木ゴテなどを用
いて行っているが、本発明の方法ではトンボで均すだけ
で充分である。Leveling after pouring the base material is normally done using a dragonfly or a wooden trowel, but in the method of the present invention, leveling with a dragonfly is sufficient.
本発明で下地材表面の目荒しとは、硬化完了前の下地材
の表面を引っ掻くことにより、該表面にまんべんなく細
かい筋目をつけることをいう。In the present invention, roughening the surface of the base material refers to creating fine lines evenly on the surface of the base material by scratching the surface of the base material before completion of hardening.
筋目の深さは０．１ｍ以上とすればよいが、作業性や下
地材中の骨材の大きさなどの点からあまり深くするのは
好ましくない、好ましくは０．３〜３０ｕ１更に好まし
くは１〜Ｉｏｎとするのがよい。The depth of the creases may be 0.1 m or more, but from the viewpoint of workability and the size of the aggregate in the base material, it is not preferable to make it too deep. ~Ion is preferable.
この処理に・よって、打設後に分離して表面に浮上して
くる、セメントや骨材に含まれていたノロや不硬化物な
どを下地材表面から除くかまたは再び下地材中に捲き込
み、更に下地材の表面積を増大させる。Through this treatment, slag and uncured substances contained in cement and aggregate that separate and float to the surface after pouring are removed from the surface of the base material or rolled into the base material again. Furthermore, the surface area of the base material is increased.

示されているような道具を用いるのがよい。To roughen the surface of the base material in the method of the present invention,
There are no particular restrictions on shape or structure as long as it can fulfill the above functions, but when the surface of the poured base material is soft, use brooms such as bamboo brooms, Mukujun brooms, scrubbing brushes, or bristles. Hard brushes, etc., or if the surface of the base material becomes hard, use a dragonfly-shaped or trowel-shaped tool made of metal, hard plastic, wood, bamboo, etc. with many hard rod-shaped protrusions, such as JP-A It is preferable to use a tool such as that disclosed in Publication No. 59-203157.

率が低下する。The distance between the rod-like protrusions may be set as appropriate, but the diameter is preferably about 5 days or less. If the distance between the protrusions is too wide, the scratching operation will have to be repeated many times, resulting in poor efficiency. Also, if the diameter is too large, the efficiency of the roughening process will decrease.
ＳＬ材層の厚さは通常、１００を基準とすることが多い

〜３０ｗ＋、局部的には５０１ｍ程度になることもある
。The thickness of the SL material layer is usually based on 100 mm, but the actual thickness may vary depending on the finish of the surface of the base material.
~30w+, locally it may be about 501m.

第１図に示すような、川の支流が本流に集まるような形
に適宜の間隔で設けるとよい。When pouring the skin onto the surface of the base material, the breathing water on the surface of the base material generated by material separation will be pushed away from the starting point to the end point of pouring the SL material, so a drainage hole should be provided in advance at the point where the pouring of the SL material ends. It is a good idea to remove the breathing water by holding the SL material to a suitable width and depth when leveling the poured base material. It is preferable to provide water guide grooves at appropriate intervals in a shape such that tributaries of a river converge on the main stream, as shown in FIG. 1, for example.

滑面を得ることができる。After pouring the base material, the SL material is subsequently poured without waiting for the completion of hardening of the base material, with or without breathing water, and without special pretreatment to eliminate breathing water. Since it can be stretched, the time required for floor construction can be significantly shortened, and the strength of the adhesive surface between the base material and the SL material can be ensured, making it possible to easily obtain a smooth floor surface.
