The column 2 is formed of, for example, a hollow rectangular prism made of steel. The beam 3 is formed of, for example, a steel H-shaped steel. The beam 3 is disposed such that the surface of the flange 31 is in a direction parallel to the foundation, and is connected to the column 2.
A deck plate 4 is bridged between the beams 3 and fixed to the upper surface of the flange 31 of the beam 3.

FIG. 2 is a perspective view of the deck plate 4 viewed from the back side, and FIG. 3 is a side view of the deck plate 4.
As shown in FIGS. 2 and 3, the deck plate 4 is formed of a thin steel plate having a rectangular shape in plan view, and one of the main surfaces (when the deck plate 4 is placed on the upper surface of the beam 3) In the surface facing the upper surface, a plurality of ribs 41 extending in one direction are provided. The ribs 41 are formed in parallel with each other at predetermined intervals, and are formed by bending the steel plates forming the deck plate 4 at a plurality of places. Both ends of the rib 41 are crushed in the height direction, and are formed so as to be able to be mounted on the upper surface of the flange 31 of the beam 3.
Between the ribs 41 on one main surface of the deck plate 4 (a position other than the ribs 41), a concave portion 42 recessed toward the other main surface is formed. The recesses 42 are respectively formed in the vicinity of both ends of the deck plate 4, and each recess 42 is in communication with the outside through the end of the deck plate 4. The communication port with the outside in the recess 42 is formed in a size that allows the spacer 5 to be inserted. Specifically, the width of the communication port is larger than the width of the spacer 5, and the height of the communication port is higher than the height of the spacer 5.
The surface of the deck plate 4 may be embossed.

FIG. 4 is a view showing a state in which the deck plate 4 is fixed to the upper surface of the flange 31 of the beam 3.
As shown in FIG. 4, the deck plate 4 is placed on the upper surface of the flange 31 of the beam 3 with the surface in which the recess 42 is formed down. The spacer 5 is inserted and fixed in a space surrounded by the upper surface of the flange 31 and the recess 42. The spacer 5 is a plate material having a rectangular shape in plan view, and is formed of the same steel material as the deck plate 4 and the beam 3. The spacer 5 is formed such that its main surface is smaller than the bottom of the recess 42 so that the spacer 5 can be completely inserted into the recess 42. The dimension of the spacer 5 depends on the adhesive strength of the adhesives 61 and 62, but for example, the longitudinal and lateral lengths are 40 mm and the plate thickness is 0.8 mm. The upper surface of the spacer 5 faces the recess 42 of the deck plate 4, and the lower surface of the spacer 5 faces the upper surface of the flange 31 of the beam 3. The adhesive 61 is injected into the gap between the upper surface of the spacer 5 and the recess 42, and the spacer 5 is fixed to the deck plate 4 by the solidification of the adhesive 61. An adhesive 62 is injected into a gap between the lower surface of the spacer 5 and the upper surface of the flange 31 of the beam 3, and the spacer 5 is fixed to the beam 3 by solidification of the adhesive 62. Then, the spacer 5 is fixed to the beam 3 and the deck plate 4 respectively, whereby the deck plate 4 is fixed to the beam 3 via the spacer 5.
The adhesives 61 and 62 can bond steel materials to each other, and are preferably, for example, a two-component mixture type acrylic adhesive. Here, as the adhesives 61 and 62, those made of the same material may be used, and when the materials of the beam 3 and the deck plate 4 are different, those made of different materials may be used.

<How to fix deck plate to beam>
Next, a method of fixing the deck plate 4 to the beam 3 will be described.
The recess 42 is formed in the deck plate 4 in advance. Here, the recess 42 is formed to communicate with the outside through the end of the deck plate 4.

Since this eliminates the need to transport the welder to the welding site, it is not necessary to consider the fall prevention measures of the welder and the routing of cables and the like. In addition, since no qualification is required to handle the adhesives 61 and 62, any worker at the construction site can fix the deck plate 4 and work efficiency can be improved.
In addition, since there is no need for welding work, there is no need to cure the lower part of the deck plate with a large cloth or the like so that sparks and other objects generated during the work do not fall, so work efficiency can be improved. .
By using the spacer 5, it is not necessary to fill the entire inside of the recess 42 with the adhesive, so the amount of the adhesive to be used can be reduced, and the construction cost can be reduced.
By sandwiching the spacer 5 between the beam 3 and the deck plate 4, the strength of the connection portion between the beam 3 and the deck plate 4 can be improved.
Since the recess 42 communicates with the outside through the end of the deck plate 4, the operation of inserting and fixing the spacer 5 into the recess 42 can be easily performed, and the operation efficiency can be improved.

<Others>
In addition, this invention is not limited to the said embodiment, It can change suitably in the range which does not exceed the scope of the present invention. For example, after applying the adhesives 61 and 62 to both main surfaces of the spacer 5, the spacer 5 is inserted into the recess 42, but is inserted into the recess 42 while holding the spacer 5. A procedure may be taken to inject the adhesive 61, 62.
Further, the recess 42 is not limited to the case where the recess 42 communicates with the outside through the end of the deck plate 4, and the recess 42 may be formed at a position away from the end of the deck plate 4. In this case, before mounting the deck plate 4 on the beam 3, it is necessary to provide the spacer 5 coated with the adhesive 61 and 62 at a position facing the recess 42.
In addition, when the bag 5 (for example, a balloon-like one) filled with the spacer 5 and the adhesives 61 and 62 is provided at the bonding portion of the deck plate 4 with the beam 3, and mounted on the beam 3 and fixed. The bag body may be ruptured to allow the adhesive 61, 62 to flow out, and the deck plate 4 may be fixed to the beam 3 with the adhesive 61, 62 that has flowed out. Here, as a method of rupturing the bag, a load may be applied from the upper side of the deck plate 4, or a hole may be made in the bag by a needle or the like.
