る。2. Description of the Related Art To perform joint construction using a so-called elastic joint material in which a reinforcing cap is covered at the upper end of a joint material body formed of a synthetic resin foam, conventionally, a metal plate or the like is used. A method is widely used in which a pair of support legs formed is attached to the side surface of a joint material, the height is adjusted by the bending angle of the support legs, and then the support leg portions are fixed with mortar.
3-51611). In this method, the fixing operation with the mortar is complicated, or the thickness of the pressing concrete located at the upper part of the mortar becomes thin and cracks occur (see Japanese Utility Model Laid-Open No. 50-54817). It has been pointed out that it cannot be cut.

材を利用しない型式の目地材が提案されている。In order to cope with the above, a support member is made of a synthetic resin foam, or a trapezoidal portion is continuously formed at a lower portion of a joint material main body to form a base portion, and a support leg or a support member is not used. A type of joint material has been proposed.

It is provided in a size of about 1.2 m, which is connected in a forward, T-shaped or cross-shaped configuration. In the joint material of the above-mentioned type, that is, the joint material having a trapezoidal portion formed continuously in the lower portion of the joint material main body, the connection is difficult because the supporting leg or the supporting member is not used. Improper connection at the ends of the joint material is not only unsightly in appearance, but also tends to cause deformation of the end of the upper cap, causing damage to the joint. Also, if the joint of the joint material is poor and the concrete is poured while the joint portion has a gap, the concrete may enter the joint portion and impair the function as the joint.
