As shown in Fig. 1, the easy demolding means for forming the coneslat of the present invention is such that it is easy to mold and quickly demolded when manufacturing the coneslat used as a concrete flooring material in a pig house, a pig house. It is composed of a main body 10 , an automatic opening/closing cap 20 , and a compressed air supply pipe 30 .

As shown in FIG. 2, the forming frame body 10 has a rectangular shape and a support leg 100 of a certain height is formed at each corner of the lower end and has a rectangular planar shape so that concrete mortar can be filled therein. A rectangular wall portion 102 is formed to protrude from the bottom 101 and the edge of the bottom 101, and the inner bottom 101 has a downward beam shape and a discharge hole forming mold 11 having a certain length. A plurality of is formed at regular intervals in the longitudinal and transverse directions.

The discharge hole forming mold 11 is formed of a downward light, as shown in FIG. 3 , a vertical piece 110 vertically extending from the top to the bottom and a predetermined height from the bottom of the vertical piece 110 . A first extension piece 111 extending toward the bottom and having a wider width toward the bottom, and a second extension piece extending from the lower portion of the first extension piece 111 to the bottom portion 100 and having a wider width toward the bottom. (112).

In more detail, the first extension piece 111 is formed to have a lower width of about 1 cm wider than that of the vertical piece 110 , and the second extension piece 112 is 2 cm wider than the first extension piece 111 . Alternatively, the width of the lower end is formed to be wide by about 4 cm, and the vertical piece 110, the first extension piece 111, and the second extension piece 112 are formed in the molding frame body 10 by the discharge hole forming mold 11 having the second extension piece 112. After curing the concrete mortar, when the cured cone slat is demolded from the mold body 10, the first extension piece 111 and the second extension piece 112 as shown in FIG. A two-stage inclined surface 1s is formed in the drain hole 1a of 1), and the separation of the cone 1 from the forming mold body 10 is facilitated by the two-stage inclined surface.

After curing the concrete mortar in the forming mold body 10 during molding, the cone slat 1 is molded after turning over the molding mold body 10 to separate the cone slat from the molding mold body 10 when curing is completed. Air is injected into the mold body 10, and the injected air allows the cone 1 to be easily separated from the molding mold body 10. The drain holes formed in the conventional cone slat do not have an inclined surface or are from the top to the bottom. It is formed in a form continuously extending to the mold, so it is not easy to separate the cone from the mold, and there is a problem in that the size of the drain hole must be formed large. When the two-stage inclined surface is formed by the first extension piece 111 and the second extension piece 112 formed as the lower part of the vertical piece 110, the constellate 1 is demolded from the mold body 10 Due to the two-stage inclined surface, it is easy to secure a space for air to enter, so that the separation of the cone 1 is made easy, and the separation of the cone 1 from the forming frame body 10 is made easy and easy.
