である。However, even in this construction method using precast concrete members, although various improvements have been made to the mutual connection structure between these members, there are not always sufficient structures and it cannot be said that it satisfies all conditions. Ta. In view of the above, the present invention was created by making a compromise between the precast concrete construction method and the on-site construction method, thereby employing the best of both methods.

である。Hereinafter, the present invention will be described with reference to the embodiments shown in the attached drawings. 1 is a longitudinally split precast reinforced concrete beam member on both sides, and a large number of rectangular reinforcing bars 2, 2', 2, etc. are connected at regular intervals. The Nada reinforcing bars and the upper main reinforcements 3, 3', 3'' are arranged in parallel, and the lower end main reinforcements 4, 4', 3'' are arranged in parallel.
4'' are similarly integrated to form a reinforcing bar cage, and the majority of the reinforcing bars 2, 2', 2 are connected in parallel, except for one side and a portion of the two adjacent sides. It is made by pouring concrete so as to be embedded in the concrete frame. 5 is an intermediate auxiliary vertically split precast reinforced concrete beam member, and evenly rectangular deep reinforcing bars 6, 6', 6'' are used.・
... are arranged in parallel at regular intervals, and upper end main reinforcements 7, 7', 7'' and lower end main reinforcements 8, 8', 8 are placed below the upper and lower sides of these rectangular deep reinforcing bars. '' are arranged in parallel and piled up to form a reinforcing bar cage, and the center portions of the upper and lower two sides of the many parallel reinforcing bars 6, 6', 6'', etc. of this reinforcing bar cage are concreted. It is embedded in the body of the sea bream and has both sides protruding from the inside of the concrete body of the sea bream.

After making the state as shown in Figure 2, passing through the overlapping part of these deep reinforcement bars, inserting the upper end main reinforcements 9, 9' and the lower end main reinforcements 10, 10', and connecting them to the bottom reinforcement bars, respectively. Necessary formwork or precast slabs are placed on the bottom part, and concrete is poured between both vertically split precast reinforced concrete beam members to complete the beam. In the case of a large beam, as shown in FIG. Beam main reinforcements 11, 11', 12, 12 are installed in the overlapping parts of the reinforcement bars protruding from sections 1, 5, 1'.
′ is penetrated, and necessary formwork or precast slabs are placed in the gap between the two, and then concrete is poured into the gap to complete the girder.

。Since the vertically divided precast reinforced concrete beam village according to the present invention has the structure as described above and is used as described above, the tin heavy machinery used for erection is small.
Moreover, by combining precast parts and on-site construction, we succeeded in shortening the construction period and reducing construction costs.
