First, the closing connector 1 is locked to the beam H at the flange H1 (attachment step). Specifically, the closing connector 1 is attached to the position of the flange H1 where the undulating portion 112 of the bridged deck plate 110 is arranged. When the closing connector 1 is attached to the flange H1 of the beam H, the distal end portion 44 of the pressing portion 42 is widened with respect to the mounting portion 41 so that the flange H1 is sandwiched between the mounting portion 41 and the pressing portion 42. , attach the closure connector 1 (see FIG. 3).

Next, the deck plate 110 is bridged between the beams H so that the closing portion 10 of the closing connector 1 closes the edge 200 (bridge process). First, one end of the deck plate 110 in the extending direction is brought closer to the closing connector 1 from obliquely upward. With the undulations 112 at one end of the deck plate 110 facing the closure 10, the other end of the deck plate 110 is lowered (see FIG. 4). In this state, the contact piece 14 of the closing portion 10 enters the inside of the inclined surface portion 113 of the undulating portion 112 of the deck plate 110 and contacts the inner surface of the inclined surface portion 113 . Since the contact piece 14 is elastically rotatable in the width direction W, it reliably contacts the inner surface of the inclined surface portion 113 .

The deck plate 110 approaches the closure part 10 while contacting the engagement part 30 of the closure connector 1 at the other end. The closing part 10 is elastically rotated to the rear side B in the direction away from the deck plate 110 in the front-rear direction FB.

In this state, the edges 200 at the ends of the deck plate 110 are closed by the closure parts 10 of the closure connector 1. FIG. In this state, the pressing portion 20 presses the deck plate 110 at the upper end face portion 114 toward the flange H1 side.

Next, a reinforcing bar 131 is arranged on the engaging part 30 and a bar arrangement part 130 is installed by arranging the reinforcing bar 131 in a grid pattern (bar arrangement step, see FIG. 5). After completion of the bar arrangement process, a concrete material is placed on the deck plate 110 to form the concrete structure 120 (see FIG. 6). This completes the process of building the composite slab structure 100 .

According to the closure connector 1 having the above configuration, several operations that have conventionally been performed in different operation processes can be combined into one operation, and the composite slab structure 100 can be constructed efficiently.

FIG. FIG. 9(b) shows a temporary fixing step (second step) in which the bridged deck plate 110 is temporarily fixed by welding to the beam H at the flat portion 111. FIG. FIG. 9(c) shows an edge closing step (third step) of closing the edge 200 with a closing cover. FIG. 9(d) shows a weld embankment (fourth step) in which a plurality of headed studs S are welded to the beam H in order to join the beam H and the concrete structure 120 together. Furthermore, although not shown, an arrangement step (fifth step) of arranging spacers on the deck plate 110, a reinforcement arrangement step (sixth step) of assembling the reinforcing bars 131 in a grid pattern on the deck plate 110, and a concrete material. There is a placing step (seventh step) of placing on the deck plate 110 .

Conventionally, the temporary fixing of the deck plate 110 and the beams H in the composite slab structure is performed by welding (second step), and a plurality of heads are attached for the purpose of integrating the concrete structure 120 and the beams H. Studs had to be welded longitudinally to beam H (fourth step). On the other hand, with the closure connector 1, at least the tacking and headed stud welding operations can be greatly reduced.

In addition, since the engaging portion 30 of the closure connector 1 according to the present invention 1 has the opening 31, it has a function of engaging with the concrete material and a function of joining the beam H, the deck plate 110 and the concrete structure portion 120 together. and a spacer function for the reinforcement 130 is provided. By using the closure connector 1 according to the present invention, the 2nd to 5th steps in the conventional construction method can be carried out in one step of the bridging process.

The closing portion 10 of the closing connector 1 is also provided with a contact piece 14 . The contact piece 14 guides the deck plate 110 with respect to the closing portion 10 when the closing portion 10 closes the edge 200, and is in elastic contact with the inner surface of the inclined surface portion 113 of the undulating portion 112 when closing the edge 200. Therefore, it is possible to reliably prevent the outflow of concrete from the edge 200. - 特許庁

Also, since the closure connector 1 has the locking portion 40, it can be easily attached to the flange H1 of the beam H. As shown in FIG.
