The floor set 24 is used to construct a ground-level floor structure and a floor structure of a multi-storey building. The beam 18 shown in FIG. 3 receives a smaller load from the floor than the girder 22, and thus has smaller dimensions such as height and width than the girder 22.

The beam 18 and spar 22 each have a pair of structural elements 30. The structural elements 30 are
It has grooves 32A, 32B, and 32C. By three grooves 32A, 32B and 32C facing each other,
Substantially rectangular first to seventh planar portions 40A-40G are formed in the structural element 30 with adjacent surfaces substantially perpendicular to each other. The structural element 30 is manufactured from a metal plate such as a steel plate, an iron plate, or an aluminum plate. High tensile steel or the like may be used as the material of the steel sheet. For example, the structural element 30 may be manufactured by bending a steel plate by pressing or the like.

The pair of structural elements 30 of the beam 18 and the spar 22 are respectively formed of three grooves 32A, 32B, and 32C of one structural element 30 and grooves 32A and 32C at both ends of the other structural element 30. Corresponding grooves 32A at both ends
, And 32C are arranged in a row in the upper and lower rows so as to face each other. The pair of structural elements 30 arranged in one row above and below are joined by a pair of steel plates or channel steels to form an H-shape to form the beam 18 and the beam 22. Here, the upper structural element is referred to as the upper structural element, and the lower structural element is referred to as the lower structural element.

In order to connect the beam 18 and the beam 22 using the connecting member 10A, first, the beam 18 and the first connecting portion 12 of the connecting member 10A are connected. When the beam 18 and the first connection portion 12 are connected, the bottom portion 36 of the first connection portion 12 becomes the second and sixth planar portions 40B of the lower structural element 30 of the beam 18.
And 40F. Further, the pair of side walls 38 of the first connection portion 12 overlap the first and seventh planar portions 40A and 40G of the structural element 30 of the beam 18, respectively. A rivet, a drilling screw, a tapping screw, a screw nail, or a bolt is passed through a hole 52 provided in the side wall 38 of the first connection portion 12 to thereby connect the first connection portion 12 and the beam 1.
8 are fixed.

Next, the connecting member 10A to which the beam 18 is connected
Is connected to the digit 22. First, the concave portion 48 of the second connection portion 20
Into the groove 32A or 32C of the spar 22. For example, FIG.
The recess 48 of the left connecting member 10A is fitted into the groove 32C of the upper structural element 30 of the left beam 22, and the recess 48 of the right connecting member 10A is fitted into the right beam 2 as shown in FIG.
2 is fitted in the groove 32A of the upper structural element 30.

At this time, in the left connecting member 10A, the first extending portion 46 of the second connecting portion 20 overlaps the sixth plane portion 40F of the upper structural element 30 of the left girder 22, and the second extending portion The portion 34 overlaps the fifth flat portion 40E, and the third extension overlaps the fourth flat portion 40D.
On the other hand, in the right connecting member 10A, the first extension portion 46 of the second connection portion 20 overlaps the second plane portion 40B of the upper structural element 30 of the right spar 22, and the second extension portion 34 is formed.
Overlaps with the third planar portion 40C, and the third extension 54
Overlap the fourth plane portion 40D.

Further, the back wall 42 of the second connecting portion 20 of the connecting member 10A overlaps the first or seventh flat portion 40A or 40G of the upper structural element 30 of the spar 22. For example, the back wall 42 of the left connecting member 10A is
Overlaps with the seventh flat portion 40G of the upper structural element 30 of the right connecting member 10A, and the back wall 42 of the right connecting member 10A
A overlaps with A. Next, the hole 5 provided in the third extension 54
Rivets into holes 60 provided in the sixth and fourth extension portions 58,
Drilling screw, tapping screw, screw nail,
Alternatively, the second connecting portion 20 and the beam 22 are fixed by passing a bolt.

Also, contrary to the above procedure, the second connecting section 2
The beam 18 may be connected to the connection member 10A after the 0 concave portion 48 is fitted into the groove 32A or 32C of the spar 22. The beam 18 and the beam 22 can be easily connected by placing the beam 18 on the bottom 36 of the connection member in a state where the second connection portion 20 of the connection member 10A is held by the beam 22 in advance.

Using the connecting member 10A, the beam 18 and the beam 22
Is connected, the height of the upper surface of the beam 18 and the height of the upper surface of the girder 22 are substantially the same, so that the height of the floor set 24 can be minimized. Therefore, the floor set 24
It is possible to minimize the height of the whole building using the slab. Further, since the second connecting portion 20 of the connecting member 10A is configured so that the concave portion 48 is fitted into the groove 32A or 32C of the spar and fixed, the bending moment applied to the connecting portion between the beam 18 and the spar 22 can be minimized. .

FIG. 4 shows another embodiment in which a beam and a girder are connected by using a connecting member 10A to form a floor set 62. While the pair of girders 22 in FIG. 3 have the same height, FIG.
In the pair of columns 64 and 66, the height of the left column 64 is higher than the height of the right column 66. Therefore, the beam is inclined from left to right. Since the connection member 10A holds the beam 18 at the bottom portion 36 and the pair of side walls 38 of the first connection portion, the beam 18 can be held even when the beam 18 is inclined. Therefore, an inclined floor structure or a roof structure can be constructed by connecting the pair of girders 64 and 66 having different heights by the beam 18 using the connecting member 10A.

By using the floor set 62, a roof structure can be easily constructed without using a complicated structure such as a truss. For example, the upper end of the inclined beam 18 is set as the vertex of the joint portion of the roof structure, and the lower end of the beam 18 is set as the end of the roof structure. Then, by installing a shingle on the beam 18, an inclined roof structure can be constructed.

FIG. 5 shows another embodiment of the connecting member.
The connecting member 10B shown in FIG.
2 has the same configuration as the connecting member 10A shown in FIGS. 1 and 2 except that the upper end of the second connecting member 12 is higher than the upper end of the side wall 38 of the first connecting portion 12. Since there is a difference between the height of the upper end of the side wall 38 of the first connection portion 12 and the height of the upper end of the back wall 42 of the second connection portion 20, the floor material having the difference of the heights is removed from the first connection portion 1.
When installed at the upper end of the second side wall 38, the height of the upper surface of the flooring material and the height of the first extension 46 of the second connection portion 20 match. Therefore, a floor structure having no step between the upper surface of the floor material and the upper surface of the girder 22 can be constructed.

For example, after connecting the second connecting portion 20 to the beam 22, the beam 18 having substantially the same height as the side wall 38 is connected to the first connecting portion 12. At this time, the height of the upper surface of the beam 18 matches the height of the upper end of the side wall 38. Since a difference in height occurs between the upper surface of the beam 18 and the upper surface of the girder 22, when a floor material having a thickness corresponding to this difference in height is installed on the upper surface of the beam 18, the height of the upper surface of the floor material and the girder are changed. 22 and the height of the upper surface thereof coincides with each other. Therefore, the floor structure has no step between the upper surface of the flooring material and the upper surface of the girder 22.

The configuration is such that the first extension part 46, the second extension part 34, and the third extension part 54 are removed from OB. Connection member 10 shown in FIG.
Similarly to B, the upper end of the back wall 42 of the second connecting portion 20 is formed higher than the upper end of the side wall 38 of the first connecting portion 12. Therefore, the beam 1 having substantially the same height as the side wall 38
8 is connected to the first connecting portion 12, and when a flooring material having a difference in height between the upper end of the back wall 42 and the upper end of the side wall 38 is installed at the upper end of the side wall 38 of the first connecting portion 12, A floor structure having no step between the upper surface of the floor material and the upper surface of the girder 22 can be constructed. In addition, the connecting member 10C includes the first extension 4
6, since there is no need to form the second extension portion 34 and the third extension portion 54, it is easy to manufacture, and the material cost can be reduced.
