At this time, since the tip of the slope forming portion 6 is arranged along the lower surface of the horizontal joint bar 3, there is a dimensional error in the horizontal joint bar 3, and the protrusion dimension L2 (see FIG. 2) changes. However, this can be absorbed by the joint material 1 and the mounting portion 7 can be brought into close contact with the inner surface of the formwork 2.

The joint material 1 as a whole rotates counterclockwise in FIG. 4A with the position near the base end of the horizontal portion 5 as a fulcrum, and a gap is generated between the slope forming portion 6 and the horizontal joint rod 3. Ready-mixed concrete may flow into the space inside the joint material 1. The inflow of the ready-mixed concrete is a serious problem since it is not known until the mold 2 and the joint material 1 are removed after the pre-cast concrete 4 is cured.

能となり、施工性を向上させることができる。As described above, the present invention relates to a joint material installed at the position of a horizontal joint bar attached to the inner surface of a formwork. A horizontal portion extending to the frame side; a slope forming portion extending obliquely downward from a tip of the horizontal portion, and a tip contacting the horizontal joint bar; and rising along a mold inner surface from a base end of the horizontal portion;
And a mounting portion fixed to the formwork via a stopper, so that the horizontal joint rod only needs to have a function of positioning the joint material, and thus the size is small. In addition to this, it is possible to easily mount the device at an accurate position. For this reason, while positioning of a joint material becomes easy, weight reduction of the whole formwork is also attained and workability can be improved.
