題がある。However, in the above-mentioned conventional method of joining the PC vertical member to the concrete member below by the simultaneous injection method of grout, the connection is made from the injection hole of one mortar filling type joint. Through the narrow gap between the reinforcing bars inserted in this joint, grout is simultaneously injected into the joint space between the PC vertical member and the concrete member and into all mortar-filled joints, and further, the grout is pushed upward. Therefore, mechanical equipment such as an injection pump having a large discharge force is required. In addition, there is a problem that the injection time varies considerably depending on the pumping capacity, the viscosity of the grout, etc., and the working efficiency is reduced.

The precast concrete vertical member is erected by building a mortar-filled joint by fitting a mortar-filled joint to the main member with a spacer interposed on the concrete member whose main bar projects upward, and the precast concrete vertical member and the concrete member formed by this spacer. The outer peripheral part of the joint space is provided with grout, and the grout is simultaneously injected into the joint space and the mortar-filled joint through the grout injection hole to integrally join the precast concrete vertical member to the concrete member.

Since it is carried out through the grout injection hole that penetrates the inside of the vertical member in the vertical direction, as in the conventional case, from the injection hole of one mortar-filled joint, through the narrow gap between this joint and the rebar inserted in the joint, PC The grout can be injected much more smoothly than the method in which the grout is injected into the joint space between the vertical member and the concrete member and into all the mortar-filled joints. Moreover, since the injection port is located above the mortar-filled joint, the grout drops in weight and reaches the upper end of each mortar-filled joint due to the head difference. Therefore, it is usually easy to inject grout without using an infusion pump.
