Also, in FIG.
The mounting piece 4 extending rearward at the same height as the mounting piece 2a of the joist hook 2 is provided on the side surface on the side of the connecting support member 5.
a is formed, and a joist screw 61 with a square washer for joist is screwed into the mounting piece 4a. The screwing of the retaining screw 33 to the spar 4 and the attachment of the joist screw 61 to the mounting piece 4a are preferably performed at a factory.

FIG. 4 shows an attachment structure of the girder 3 to the joist 2 and the girder 4. On the end face of the joist hook 2 side of each joist beam 3, a joist beam bracket 41 formed in a deformed L shape is screwed sideways. The fixing piece 41 a of the bracket 41 for the girder is screwed to the inner wall surface of the girder 3 so as to be inserted into the hollow portion 3 a of the girder 3.
b is a screw hole 4 through which the upper large coach screw 12 is inserted.
2 and a downward cutout hole 43 in which the lower large coach screw 12 is hooked. Thereby, the notch hole 43 is hooked from the upper side to the lower large coach screw 12 screwed halfway into the joist hook 2, and the end of the girder 3 on the joist hook 2 side is forwardly attached to the joist hook 2. It is designed to be hooked in a retaining state. The attachment of the bracket 41 for the girder to the girder 3 is preferably performed at a factory.

On the other hand, a corner member 51 is screwed to an end of the girder 3 on the side of the beam 4. Corner member 51

FIG. 5 shows an attachment structure of the joist 6 to the joist hook 2 and the girder 4. As described above, joist hanging 2 and girder 4
The mounting pieces 2a and 4a are respectively opposed to each other.
Are provided, and a joist screw 61 is screwed into the mounting pieces 2a and 4a. A mounting piece 6a extending laterally from the lower end is formed in the joist 6, and cut-out holes 62, 6 are formed on the joist hook 2 side and the girder 4 side of the mounting piece 6a, respectively.
2 are formed. Each cut hole 62 is made of a joist screw 6
One shaft portion has a width to be inserted, and extends in parallel to the end face of the joist 6. When the both ends of the joist 6 are laid over the mounting pieces 2a, 4a of the joist hook 2 and the spar 4, respectively, when the joists 6 are slid toward the joist screws 61, 61 in the temporarily tightened state, the cut holes 62 are formed. The joists 6 are received by the joist screws 61 so that the joists 6 can be hooked on the joist hooks 2 and the spar 4 in a state where the joists 6 cannot be pulled out upward.

The procedure for assembling the framework of the deck 1 constructed as described above will be described step by step with reference to FIG. First, one end of the joist hook 2 is lifted up and applied to a desired position on the outer wall W, and this end is temporarily fastened to the outer wall W with a small coach screw 11. Next, the other end of the joist rack 2 is lifted, and after being horizontal, the small coach screw 11
This end is fully fastened to the outer wall W. Here, the small coach screw 11 in the temporarily tightened state is fully tightened, and the outer wall W of the joist hook 2 is tightened.
Temporarily fix to.

Next, each connecting support member 5 incorporating the column 7 is connected.
The end on the side of the joist hook 2 is hooked to the joist hook 2, and the column 7 is set at a predetermined position while being horizontal. Here, after finely adjusting the position of the connecting support 5 in the front-rear direction along the long hole 23 of the connecting support bracket 21, the screws 22 for the connecting support are fully tightened, and
Is fixed to the ground (placement of foundation concrete). When the foundation concrete has solidified, lift one end of the girder 4 and hook it to the end on the girder 4 side of one connecting support 5 and then lift the other end and likewise connect the other end It is hooked on the end of the support member 5 on the side of the beam 4. In this state, while the one end of the spar 4 is moved up and down along the screw hole 35, the fool hole 34 of the spar bracket 31 is aligned with the screw hole of the spar 4,
A girder screw 32 is temporarily fastened to one end of the girder 4. Similarly, while leaving the level of the spar 4, the spar screw 32 is screwed into the other end (final tightening), and the preceding spar screw 32 is fully tightened again. 5 is fixed.

Next, the end of each joist beam 3 on the joist hook 2 side is lifted, and is hooked on the large coach screw 12 on the lower side.
Side end is fitted to the girder 4 and the girder 3 is joisted 2 and girder 4
Temporarily fix it in such a way as to span it. Then, the lower large coach screw 12 is fully tightened.
2 is screwed (finally fastened), and by this joint fastening, the permanent fixing of the joist hook 2 and the joist hook 2 of the girder 3 is simultaneously performed. next,
The girder screw 52 is screwed into the girder 4 to fix the girder 4 side of the girder 3 to the girder 4. Finally, after the joist 6 is placed so as to be passed to the joist hook 2 and the girder 4, it is slid in the left-right direction to lock both ends of the joist screws 61, 61.
1 and 61 are fully tightened, and the joist 6 is fixed to the joist hook 2 and the spar 4. Thereafter, the operation shifts to the work of laying deck materials.

As described above, according to this embodiment, as the structural materials of the deck 1, each of the joist rack 2 having a length and weight, the connecting support member 5 incorporating the column, the girder 4, the girder beam 3 and the joist 6 are used. At both ends, each member can be latched (temporarily fixed) to another member in a retaining state, so that when each member is incorporated into another member, it is not necessary to lift the entire member, and at the time of fixing In addition, there is no need to support the member. That is, the assembling work and the fixing work of each member to another member can be separated, and each member can be incorporated into another member one by one. Therefore, the assembling work of the deck 1 can be performed efficiently, and the assembler can perform the work alone. Moreover, the work such as screwing can be transferred to the work in the factory, so that the construction period as a whole assembling work can be shortened.

The large coach screw 12 allows the joist hook 2
And the girder 3 are fixed to the outer wall W by fastening together, so that the number of parts and the number of assembly steps can be reduced, and the work can be performed more efficiently.

In the above embodiment, in addition to the girder beam, the deck is supported by using the connecting support member with the built-in post. However, the girder beam is not required, and the connecting support member also serves as the girder beam. You may. In this case, the cost and the construction period can be further reduced. Further, each bracket may be formed integrally with each structural material. Furthermore, the shape and structure of each bracket and the hole for retaining the bracket are arbitrary as long as they can be inserted and removed with respect to the corresponding screw and can be prevented from coming off in a desired direction. Still further, the corner member may be constituted by a bracket for simply joining the girder and the end beam at a right angle.

[0026]

As described above, according to the structures such as terraces and balconies of the present invention, when assembling each structural material to another structural material, each structural material is incorporated into another structural material one by one. Accordingly, the assembling work can be performed efficiently, and the assembler can perform the work alone. In addition, since the assembling work can be performed in a state where various screws are screwed into the respective structural members, the screwing work of these screws can be performed at a factory, and the assembling work can be performed efficiently and in a short time. Can be done between.
