However, since the structure is dense, the adhesion to the concrete to be poured is low, and it is difficult to bear the load together with the concrete, and when it is used only as a formwork and exterior material. There are many.

粗度は低く、付着力の増大はさほど期待できない。Therefore, a wire brush is applied to the surface,
Even if you apply a green cut method that sprays sand and roughens the surface, only a fine silica surface appears,
The roughness is low and the increase in adhesive strength cannot be expected so much.

下面は、緻密な外面６とされる。Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes an embedded formwork plate of the present invention. The embedded formwork plate 1 is a laminate of a mortar layer 2 and a concrete layer 3. As an aggregate, the mortar layer 2 contains only fine aggregate. In addition to fine aggregate, gravel, crushed stone or the like having a size of 15 to 20 mm is used as the coarse aggregate 4 in the concrete layer 3. And on the surface of the concrete layer 3, coarse aggregate 4
The uneven surface 5 is exposed, and the lower surface of the mortar layer 2 is a dense outer surface 6.

強度部材となると共に外装材となる。As shown in FIG. 2, for example, the embedded formwork plate 1 is assembled into four form cylinders 7 to form a formwork, and concrete 8 is poured into the formwork to form the square cylinders 7 and the concrete 8.
Is used to form a pillar that is integrally connected. Therefore, the buried formwork plate 1 serves as a formwork for the concrete 8, but after the concrete 8 is hardened, it becomes a strength member integral with the concrete 8 and an exterior material.

いる。In order for the embedded formwork plate 1 to sufficiently bear the load as a strength member, it is necessary that the concrete 8 adheres with a strong adhesive force. Therefore, the surface of the concrete layer 3 has a rough aggregate. An uneven surface 5 having an exposed portion 4 is formed.

積層体１３として搬送させる。To manufacture the buried formwork plate 1, as shown in FIG. 3, an extruder 10 for extruding the mortar layer 2 through the die hole 10a and an extruder 11 for extruding the concrete layer 3 through the die hole 11a. Are placed one above the other and the die hole 10a
While the mortar layer 2 coming out of the mortar layer 2 is placed on the conveyor 12 and conveyed, the concrete layer 3 is superposed on the mortar layer 2,
It is conveyed as a laminated body 13.

は数ｍｍ程度とする。Next, after being cut to a certain size, the retarder 14 is applied to the upper surface of the concrete layer 3 before hardening as shown in FIG.
Is sprayed onto the mortar on the surface of the concrete layer 3 and the lower layer is cured. The penetration depth of the retarder 14 is about several mm.

る。Next, when the mortar in the surface layer portion, which has been delayed in hardening by the retarder, is washed away, the upper part of the coarse aggregate 4 is exposed from the hardened mortar portion of the concrete layer 3 and unevenness due to uneven penetration of the retarder is caused. Overlap with each other, and the uneven surface 5 having a complicated and large surface area appears. Thereby, the buried formwork plate 1 having a high adhesiveness with the concrete 8 to be poured can be obtained.

Alternatively, the mortar may be removed by scraping.

き強い付着力が生じ強固に結合する利点がある。As is apparent from the above description, since the buried formwork plate of the present invention is made of ordinary mortar and concrete, it has an advantage that it can be manufactured at low cost. Then, the surface of the coarse aggregate is exposed from the concrete layer to form an uneven surface, and since the mortar part also has unevenness and forms a wide adhesion surface, a strong adhesion force is obtained when the mold is assembled and concrete is driven in. There is an advantage that it occurs and is firmly bonded.

易に製造できる利点を有する。Further, according to the production method of the present invention, a laminate of a mortar layer and a concrete layer is formed by using a commonly used extrusion-molding means, and the mortar component on the surface layer of the concrete layer is removed. Since the uneven surface is formed only by doing, there is an advantage that it can be easily manufactured without using a special tool or member.
