Description of the Related Art In recent years, with the automation of construction methods for steel-framed buildings (a fully automatic building construction system), a method of connecting a PC slab to a steel beam instead of a slab slab by a formwork method has been adopted. ing. In this method, connecting ends of PC slabs to be connected to each other are installed on a steel beam, and a gap (groove) formed between the ends of the PC slabs.
Mortar, concrete and other fillers are integrated and integrated, so conventional work such as assembling and dismantling of formwork and supports, dismantling, and casting concrete in place can be largely omitted. . Therefore, the floor slab is
The use of the C-plate is advantageous for labor saving and is considered to be a necessary floor construction method system when the construction is automated.

プするおそれがあった。However, since it is difficult to join and integrate with a steel beam, it is difficult to secure out-of-plane rigidity (stiffness effect as a composite beam). Effective), and it was not possible to treat it as a composite beam. This is because we do not treat as a composite beam,
Floor slab construction is easy, but in the case of high-rise buildings, the structure tends to be soft and easy to shake, which means that it is necessary to increase the steel beam size and increase rigidity to compensate for it . Therefore, since the rigidity of the steel frame is increased, the use amount of the steel frame is increased, and there is a possibility that the cost is significantly increased.

クリート等の充填材２４を充填する。FIG. 6 shows a method of connecting a PC floor slab disclosed in Japanese Patent Application Laid-Open No. H8-60776. In the case of this connection method, a recess 16 is formed at the connection end of the PC floor slab 12 so as to be cut out in an L-shaped cross section from the end face to the upper side.
An angle steel 18 having an L-shaped cross section is embedded along the bottom surface 16a and the side surface 16b. At this time, the angle iron 18 is welded to the anchor bar 14 of the PC plate 12. When connecting the PC slab 12, the PC slab 12 is placed on the flange 10a of the steel beam 10 with the connection ends thereof abutting each other. In this state, the horizontal wall 18a of the angle iron 18 embedded in the recess 16 is set. The connecting steel plate 20 is bridged across the connecting steel plate 20 and the horizontal wall 18a.
And weld. Next, a filling material 24 such as mortar or concrete is filled in the groove 22 formed by the concave portion 16 at the butted portion of the PC floor slab 12.

ことが構造的に困難である。However, in the above connection method, the connecting steel plate 20 is bridged across the horizontal wall 18a of the angle iron 18 embedded in the concave portion 16, and the end face of the connecting steel plate 20 is fillet welded to the horizontal wall 18a. By doing so, the connection between the two is achieved, and it is structurally difficult to absorb the upper and lower construction errors.

のレベル調整を必要とし、施工作業性が悪い。More specifically, the PC floor slab 12 is placed on the steel beam 10 with the connecting ends thereof abutting, and in this state, the connecting steel plate 20 is laid across the horizontal wall 18a of the angle steel 18 embedded in the concave portion 16. At that time, if there is a vertical misalignment between the two horizontal walls 18a, even if it is a slight error, an unevenness occurs between the connecting steel plate 20 and the horizontal wall 18a,
Good welding cannot be performed. Therefore, level adjustment between the two horizontal walls 18a is required, and construction workability is poor.
【０００８】また、溶接は接続鋼板２０の端面でのみ行
われているため、剛性の確保が片面的となる。Further, since the welding is performed only on the end face of the connection steel plate 20, the rigidity is one-sided.

Because the joints are joined, even if the height positions of the steel plates are slightly shifted due to construction errors, the height positions of the connecting steel plates can be adjusted and absorbed, and the positions of the steel plates Even if it is shifted, it can be dealt with by shifting the position of the connecting steel plate in the horizontal plane within the range of the width of the steel plate. Further, since both ends of the connection steel plate can be welded to both sides of the steel plate, greater rigidity can be obtained as compared with conventional single-side welding. Therefore, it can be sufficiently used as a composite beam. Further, since the connecting steel plates are arranged in the vertical direction, the connecting steel plates effectively function together with the studs to prevent slippage of post-cast concrete.
