    Abstract: PROBLEM TO BE SOLVED: To simplify a treatment work for peeling off prevention, and raise adhesion by the use of an auxiliary tool for mortar adhesion in which a flat base plate part to be fixed on the floor surface of an exterior wall and a number of locking parts to be buried and locked to mortar are molded integrally with resin. SOLUTION: The auxiliary tool for mortar adhesion 5 is formed so that a disclike base plate part 1 consisting of fiber-reinforced resin and a number of looplike locking part 2 being projected in row at one side surface of a base plate 1 are molded integrally. Firstly the exterior surface of a mortar outer layer 22 is contacted with the rear surface side of the base plate 1 of the auxiliary tool 5, and an anchor pin 23 is driven in an insertion hole 4. When uncured mortar 24 is applied, the locking parts 2 come deeply in the inner part of mortar 24, so that mortar 24 solidifies covering the joint part 2 so as to crease a high adhesion. Also, the base plate 1 is increased in its strength and elastic modulus, and the locking parts 2 come to have characteristics of large toughness and tenacity, and further its supporting strength is improved, as a result, mortal 24 is further more prevented from peeling off.

    Abstract: PROBLEM TO BE SOLVED: To improve pull-out load, corrosion resistance for concrete and cost reduction by forming a cylindrical main body with a polyamide resin containing short glass fiber and by forming projected portions in one united body on the outer peripheral portion of the main body. SOLUTION: A cylindrical device P is embedded in a concrete panel segment and used as a coupling portion for suspending metal. The cylindrical device P is made by forming a ring-shaped projected portion 2 on the outer peripheral wall of a cylindrical main body 1 and a recessed portion 4 formed in one multi- stage body with an internal thread 3 formed on the inner peripheral wall. The cylindrical device P is made of a fiber-strengthened polyamide resin containing 15 to 45 wt.% short glass fibers thereby increasing the tensile strength and modulus of elasticity of the cylindrical device P and also increasing the pull-out load by the unique construction of the projected portion 2. Also, it can be easily formed by the injection molding at a low manufacturing cost.
