この発明は、土間コンクリート構造及びその施工方法に
関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a concrete structure with an earthen floor and a method of constructing the same.
（従来の技術）
従来、土間コンクリートの構造において、第２図に示す
ように土間コンクリートＣの誘発目地Ｍに樹脂モルタル
Ｐを充填するのみてあった。(Prior Art) Conventionally, in the structure of concrete with a dirt floor, as shown in FIG. 2, the induced joints M of the concrete with a dirt floor C are filled with resin mortar P.
他の例としては、第３図に示すように土間コンクリート
Ｃ１の誘発目地Ｍ１の上端角部にアングルＡ、Ａを取付
け、アンカー筋で固定して、誘発目地の角部を補強する
ものであった。As another example, as shown in Fig. 3, angles A and A are attached to the upper corner of the induced joint M1 of the concrete floor C1 and fixed with anchor bars to reinforce the corner of the induced joint. Ta.
（発明が解決しようとする課題）
第２図に示す従来例では、土間コンクリート上を例えば
台車等か走行すると、誘発目地の上端角部が欠ける問題
かあった。(Problems to be Solved by the Invention) In the conventional example shown in FIG. 2, when a truck or the like runs on a concrete floor, there is a problem in that the upper end corner of the induced joint is chipped.
第３図示の例では、アングルが一端角部を保護するため
に上側のような問題は生しないが、コンクリート収縮に
より誘発目地幅が広がり、土間コンリートの上面と目地
との間に段差ができ、このために台車等が誘発目地上を
通過する毎にガタ付いて台車等の円滑な走行が妨げられ
る他に、振動音が発生し、騒音の原因となっていた。In the example shown in Figure 3, the angle protects the corner at one end, so the problem like the upper side does not occur, but the induced joint width increases due to concrete shrinkage, and a step is created between the top surface of the concrete floor and the joint. For this reason, each time the cart or the like passes over the trigger joint, it rattles, which not only prevents the cart from running smoothly, but also generates vibration noise, causing noise.
この発明の目的は、目地幅が広がっても、台車等の円滑
な走行が妨げられることがなく、騒音の発生を抑制する
ことである。An object of the present invention is to suppress the generation of noise without hindering the smooth running of carts and the like even when the joint width increases.

リート１との付着を断っている。A protection member 3 made of a rope with a T-shaped cross section is provided at one end corner (upper end corner) 11.12 of the induced joint 2 of the concrete floor 1. The horizontal portion 31 of the protection member 3 covers the corner portions 11 and 12 at one end of the induced joint 2, and its upper surface forms the same plane as the upper surface of the concrete floor 1. The vertical portion 32 of the protection member 3 is located within the induction joint 2. In the protective member 3, extend the anchor reinforcement 4 diagonally downward from the intersection of the horizontal part 31 and the vertical part 32 at one (left) end corner of the induced joint 2, and attach the protective member to the earthen floor concrete. It is fixed at 1. Further, the adhesion preventing surface 33 of the protection member 3 facing the corner portion 12 at the other end, that is, both surfaces of the horizontal portion 31 and the vertical portion 32, is prevented from adhering to the dirt floor concrete 1 with grease or asphalt.

The same plane is ensured.

Due to the subsequent curing, the protection member 3 has an anti-adhesion surface 33 on one end corner 12 side of the dirt floor concrete 1.
It is fixed to the earthen floor concrete via the anchor reinforcement 4 in a state where the adhesion is broken.
