Description

[Detailed explanation of the invention] This invention is a balcony deck mounting structure, and more specifically, a deck that can be easily installed at the installation site from a deck unit assembled as a single unit by connecting the deck plate to the joists in a factory etc. This relates to the mounting structure.

For conventional balcony decks, the component parts are transported to the installation site in pieces, that is, in an unattached state, and after the pillars are erected, beams are placed between each pillar and between the pillar and the building in a U-shape. Alternatively, it is suspended and fixed in a cross-section shape, and a large number of joists are hung separately between opposing beams and fixed to the beams by screws or welding, and deck plates are placed side by side on the top of the joists and attached to the joists. They are constructed and installed in a sequentially fixed manner.

Therefore, since the deck components are independent until they are assembled on site, it takes a lot of effort and time to load and unload them onto transport vehicles, handle them at the installation site, and connect each component. Each joist supporting the joists is attached to the beam separately, and a deck plate is attached to each joist to attach the deck section, which has the drawback of requiring a long construction time.

Therefore, the inventor of this invention connected the joists and deck plates in advance in a factory, assembled them into a single unit, transported this to the installation site, and installed it at the site by simply lifting the deck unit and connecting it between the columns and between the columns and the frame. We devised a deck unit that can be easily installed by simply fixing it to a beam suspended between the two.

The purpose of this invention is to provide a mounting structure that can safely and reliably fix this deck unit with as few steps as possible, thereby simplifying the on-site construction of a balcony and shortening the construction time.

Next, one embodiment of this invention will be described in detail based on the drawings.

FIG. 1 is a plan view of a balcony B with a deck unit D mounted thereon using the deck mounting structure according to the invention, attached to a building H.

Pr, Pc, and Pt are pillars, h f and h f' are handrails on the nail surface, and hsths' are handrails on the side.

In general, a deck unit only needs to have a deck plate and a joist for supporting the deck plate by withstanding vertical loads and fixing it to a beam. When fixing to the beam, it is necessary to fix each joist to the beam, which is undesirable because the number of fixing operations increases by the number of joists.

If both longitudinal ends of the joists are fixed to the connecting rails on the same side of each joist, then in order to fix the decking unit to the beam, all you have to do is fix the two rails at each end of the joists. Often the number of fixing points can be minimized.

Therefore, in this invention, as shown in FIG. 2, a deck joist 3 is stretched across and fixed between the parallel front rail 1 and rear rail 20, and a deck plate 4 is fixed to the upper surface of the joist. The purpose of this invention is to provide a mounting structure that allows for easy mounting.

The deck unit D has a front rail 1 formed into a long length with a cross-sectional shape, and a rear rail 2 similarly formed into a long length with a cross-sectional shape. A plurality of joists 3 are arranged parallel to each other on a common plane, and between the two rails, extending from one rail 1 to the other rail 2 in a direction perpendicular to the longitudinal direction of the rails. Each joist is arranged at an appropriate interval and fixed to both rails, and a plurality of deck plates 4' extending in a direction parallel to the rails are placed and fixed on the upper surfaces of the joists.

To explain in more detail, the front rail 1 has a horizontal part 1a and a vertical part 1.
b, and the vertical portion 1b extends above the upper surface of the deck plate 4 placed on the joist 3, and its height is appropriate for abutting and supporting the upper end of the inner surface of the front beam 9, which will be described later. Height is set.

Further, in the horizontal part 1a, holes 1 are provided at appropriate intervals in the longitudinal direction.
c is provided.

The rear rail 2 also has a horizontal part 2a and a vertical part 2b, and the vertical part 2
b has a height equal to the upper surface of the joist 3.

A similar hole 2c (FIGS. 13 and 14) is provided in the horizontal portion 2a.

As shown in FIG. 3, the joist 3 is made, for example, in the shape of a rectangular tube, and has a screw hole 3a inside.

Then, both end surfaces in the longitudinal direction are brought into contact with the vertical parts 1b and 2b of the rails 1 and 2, respectively, and screws 5 are inserted from the outside of each vertical part.
By screwing into the screw hole 3a, the rail 1
, 2 and each joist 3 are fixed.

However, any other means of securing the rail and joist may be used.

The deck plate 4 integrally has a fitting groove 4a extending in the longitudinal direction at one end in the width direction, a locking edge 4b at the other end, and a groove 4c opening on the upper surface in the middle. The deck plate is brought close to the rear rail 2 and fixed by screwing the screws 6 into each joist 3 from the groove 4c, and the locking edge 4b of the next deck plate is pushed into the insertion groove 4a of the previously fixed deck plate. Similarly, remove the screw 6 from the groove 4c.
Screw into each joist 3 and fix.

Thereafter, other deck plates are connected and fixed like a single plate in the same way, without forming gaps between them that may cause rain leaks.

7 is the groove 4c after fixing the deck plate to the joist.
This is a cover that fits into the groove to close the groove.

The deck plate 4 may be a single piece having a width from the front rail 1 to the rear rail 2 and having grooves 4c at appropriate intervals in the width direction.

However, in order to facilitate manufacturing and handling, the illustrated example is generally used.

As mentioned above, the front and rear rails 1.2
, a plurality of joists 3 and a plurality of deck plates 4 are connected in advance at a factory or the like using screws 5 and 6 and assembled into a single unit, and this is transported to the balcony installation site.

The balcony shown in FIG. 1 uses two deck units connected together.

Therefore, loading and unloading onto the transport vehicle and handling at the site can be carried out with only 21 deck units, so that the time required for loading and unloading and handling is greatly reduced.
