The vertical plate part 4C is configured to be fixed to the vertical plate part 4C using fasteners 18 such as bolts and nuts.

The beam mounting bracket A is integrally formed by bending a metal plate, etc., and has hook portions 19 a and 1 at the upper end.
A pair of left and right vertical plate portions 19b having a diameter of 9 a'.

19b', and both vertical plate parts 19b, 19b'
The connecting plate portion 19C has a substantially U-shaped planar shape and is dimensioned to tightly fit into the hollow portion of the beam 5.

Also, both vertical plate portions 19b. 19b' has a vertically elongated hole in its upper half and a round hole in its lower half, and the stopper 15 is inserted between these holes and the horizontally elongated holes in the vertical plate portions 4a and 4f. It is configured to pass.

Round holes for fasteners 20 such as bolts and nuts are formed in both side surfaces of the connecting plate portion 19C and the beam 5 that fits on the outside thereof, so that the two parts 19C and 5 are tightened and fixed. It is configured.

Therefore, when connecting the girder 4 and the beam 5, for example,
First, the hook parts 19 a and 19 a' of the beam mounting bracket A are hooked and placed on the hook part 4 g and the vertical plate part 4 a of the girder 4 from above, and then the vertical plate parts 19 b and 19 b' of the bracket A are hooked and placed. are applied to the vertical plate portions 4a and 4f of the girder 4, and both are tightened and fixed with the fasteners 15.

In this case, the hook parts 19a and 19a' are connected to the vertical plate part 4a.
Since the beam attachment fitting A is temporarily fixed on the girder 4 by being hooked on the hook portion 4g along the line, the position of the fitting A and the operation of the stopper 15 can be easily performed.

Next, the end of the beam 5 is attached to the connecting plate part 19C of the beam mounting bracket A.
The fitting part of both 5 and 19C is fitted to the outside of the stopper 20.
The bolts are tightened and fixed, thereby allowing the girder 4 and beam 5 to be connected as shown in FIG.

This work is also performed with the beam 5 temporarily fixed by the beam mounting bracket A, that is, with the weight of the beam 5 being supported by the connecting plate portion 19C, so that the fasteners 20, etc. can be easily operated. Moreover, as mentioned above, the vertical plate part 19
b, 19b' are integrated by the connecting plate part 19C, so for example, when connecting a girder and a beam using a pair of separately manufactured angle members, There is no inconvenience that the distance between the angle members deviates, and the beam attachment fitting A can also be used as a connecting fitting between the abutting ends of the beams 4 when connecting the beams 4 to each other.

In FIG. 3, 21 is a beam support angle that connects the beam 5 and the beam support column 6, and 22 is a fastener such as a bolt or nut for tightening or fixing these.

The hanging plate portion 4d functions as a positioning portion that engages with the upper edge of the wall panel 8, a reinforcing portion for the girder 4 itself, and a portion for preventing rainwater from entering.

Note that the girder 4 is not limited to the one in the above embodiment; for example, the longitudinal cross section has an e shape or the one shown in FIG.

Since it is in contact with both sides of b, it is strong against forces in the left and right directions, and since lip b is present, it is also strong against forces in the vertical direction.

The hole for inserting the stopper 25 provided in the hollow rectangular cylindrical shaft body 23b is a horizontally elongated hole so that the positional relationship with the main building 7 can be adjusted in the longitudinal direction of the main building 7. 2
4 is provided with a tapped hole for screwing into it.

Note that 7C is a stopper insertion hole. In addition, among the purlin mounting brackets B, the purlin mounting bracket B, which is fixed on the beam 5 at the end in the girder direction, has a mounting piece 23a' at one end of the horizontal plate part 23H for attaching other objects such as a throat plate. It is desirable to form it by folding it in one piece.

Further, in the above embodiment, the horizontal plate portion 23a is directly fastened to the upper surface of the beam 5 using the fastener 24, but for example, as shown in FIG. Plate portions 23C bent downward at right angles are provided at both ends of a, and these plate portions 23C are placed against both sides of the beam 5, and are configured to be fixed with fasteners 24. It is also possible to implement.

It is manufactured by bending process, and has a T-shaped planar shape.

That is, the horizontal plate part 26a and the vertical plate part 26b located at the middle part in the longitudinal direction form a T-shaped planar shape, and the vertical plate part 26b has a hole 27 for inserting an anchor bolt. .

Reference numeral 28 indicates a first rising piece bent at the inner edge of the vertical plate portion 26b, and reference numeral 29 indicates an edge formed at the longitudinally intermediate portion of the horizontal plate portion 26a and on the opposite side from the vertical plate portion 26b. The second rising pieces 30 and 31 are formed by bending, and the third rising pieces 30 and 31 are bent in pairs at both ends of the horizontal plate portion 26a in the width direction at both sides of the second rising piece 29. It's a piece.

Reference numeral 32 denotes tapped holes formed in each of these rising pieces 28, 29, 30, and 31 by burring.

The above-mentioned foundation metal fitting C is fastened onto the foundation concrete 13 through the hole 27 and the anchor bolt 14, and the metal fitting C is connected to the lower frame 2, stud 3, and beam support column 6 as follows. There is.

That is, as shown in FIG. 6, the third rising piece 30 and the fourth rising piece 31 have opposing ends of a pair of lower frames arranged in series aligned with the outer surfaces of the respective rising pieces 30 and 31. Similarly, the lower end of the stud 3 is placed on the outside of the second rising piece 29, and the lower end of the stud 3 is placed on the outside of the second rising piece 29, and the lower end of the stud 3 is placed on the outside of the second rising piece 29.

When placed on the top surface, the main building, which has a flower-shaped longitudinal section and is composed of a groove-shaped plate section opening downward and a lip bent outward from the surface, is attached to the beam using a stopper. The lower surface of the groove bottom of the template portion contacts the upper edge of the hollow square cylindrical shaft,
Since the lip is fitted into the hollow rectangular cylindrical shaft in a state raised from the horizontal plate part, and the fitting parts of both are fixed with a stopper, the following effects can be obtained. It will be done.

That is, the hollow rectangular cylindrical shaft of the purlin mounting bracket is strong against vertical and horizontal forces, and the purlin, which has a flower-shaped longitudinal section, is attached to its groove-shaped plate. The lower surface of the groove bottom of the part is in contact with the upper edge of the hollow square cylindrical shaft, and the lip of the purlin is raised from the horizontal plate part of the lower end of the hollow square cylindrical shaft. The load is supported by the hollow rectangular cylindrical shaft that is strong against vertical and horizontal forces, and the main building does not wobble and is extremely robust.

Moreover, since the purlin is fitted to the hollow square cylindrical shaft with its lip raised above the horizontal plate at the lower end of the hollow square cylindrical shaft, the length of the hollow square cylindrical shaft is Therefore, even if the length of the hollow rectangular cylindrical shaft body is changed according to the roof slope, a purlin with the same vertical width can be used, and many types with different vertical widths can be used. There is no need to prepare the main house.

Moreover, since the vertical cross section of the purlin is hole-shaped, simple manufacturing methods such as bending of colored iron plates can be adopted, and since the purlin mounting bracket has a simple structure, there are fewer welding points, making it easy and inexpensive. There are effects that can be produced.
