DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings, in which the prefabricated outer corridor 1 according to the present invention is applied to a two-story apartment building 2 which is a building.

The prefabricated outer corridor 1 according to the present invention is, for example,
As shown in FIG. 1 and FIG. 2 or FIG. 5, a girder 4 is provided in a substantially horizontal direction along a side wall 3 of an apartment 2, and a plurality of pillar members are separated from the side wall 3 by a predetermined distance at predetermined intervals. 6 is erected, and the front girder 5 is laterally installed between these pillars 6. A joist 7 is installed between the receiving girder 4 and the front girder 5 to form a shaft assembly.

Structural members such as the receiving girder 4, the front girder 5, the column member 6, and the joists 7 used for the above-mentioned frame assembly are formed in a desired shape or size in advance in a factory, and necessary brackets are also attached. is there.

On the other hand, the flooring unit 8 laid on the above-mentioned frame is a substantially rectangular frame member 11 having a vertical member 9 and a horizontal member 10, and a floor plate 1 attached to the upper surface of the frame member 11.
2 and the floor plate 12 is attached to both ends of the frame member 11 leaving a mounting space 13 in which a suspending tool described later can be mounted. This floor material unit 8 is also produced in the factory together with the above-mentioned structural members.

The floor unit 8 will be described in more detail with reference to FIGS. 1 and 4. The floor material unit 8 comprises a pair of facing vertical members 9 and horizontal members 1 made of square pipe material or C-shaped steel.
0 is formed in a substantially rectangular shape, a plurality of auxiliary vertical members 9a are interleaved in a ladder shape between the horizontal members 10 in a direction substantially parallel to the vertical members 9, and at the same time, two auxiliary vertical members 9a are substantially parallel to the horizontal members 10. The frame member 11 is formed by interposing the auxiliary horizontal members 10a between the vertical members 9 in a grid pattern.

A floor plate 12, which will be described later, is attached to the frame member 11 as described above, leaving a mounting space 13 at which both ends can be fitted with a suspender, and the floor member unit 8 is thus constructed. This floor material unit 8 includes, for example, a 3M unit (8a) capable of attaching six floor plates 12 described later as shown in FIG. 4 (A), and four floor plates 12 as shown in FIG. 4 (B). Although a 2M unit (8b) that can be attached is prepared, the floor plate 12 is not attached at both ends in the factory to form a mounting space 13 at which the suspending tool can be mounted. That is, since the floor board 12 is not attached to the end of the frame member 11 in the longitudinal direction (longitudinal direction of the outer corridor), a space is provided between the vertical member 9 and the horizontal member 10 or the auxiliary vertical member 9a and the auxiliary horizontal member 10a. Therefore, a suspending tool can be attached to the vertical member 9 and the horizontal member 10 or the auxiliary vertical member 9a and the auxiliary horizontal member 10a, and especially when laying the auxiliary horizontal member 10a and the auxiliary vertical member 9a. Since it does not interfere with the receiving girder 4, the front girder 5, and the frame material 11 already laid, it is possible to mount the suspending tool at a desired position and in a hanging manner. It is to be noted that the vertical members 9 and the horizontal members 10 can also be mounted by attaching a suspending tool such as a hook to the outside from the mounting empty portion 13 side. In this mounting mode, the girders 4, 5 and the like can be installed. It does not interfere with.

As shown in FIG. 4 (A), the floor material unit 8 includes a standard type in which the auxiliary cross member 10a projects from the vertical member 9, and as shown in FIG. 4 (B), the auxiliary cross member 10a. For the ends (for the wives) that do not protrude from the vertical member 9 are prepared in the respective lengths.

The floor plate 12 attached to the frame member 11 having the above-described structure has a metal core material 14 formed of, for example, a damping steel plate or a general steel plate, and a coating layer 15 made of synthetic rubber or the like.
It is a rectangular plate material coated with. Also, this floor board 12

When the and are formed, in order to connect the adjacent floor boards 12,
When the first step portion 16 and the second step portion 17 are fitted to each other, the projecting piece 17b and the groove portion 17a are deformed and the first step portion 16 and the second step portion 17 are brought into close contact with each other in a watertight manner. Therefore, the watertightness is remarkably improved, and no water leaks downstairs.
The first step portion 16 and the second step portion 17 are, of course, formed on the floor plate 12 that is fixed to the frame member 11 at the factory in advance, and also on the floor plate 12 that closes the mounting space 13 later on site. It is formed and can be fitted in the same procedure.

Further, the first step portion 1 provided on the side edge of the floor plate 12
6 and the second step portion 17 can also be formed in a corrugated shape, as shown in FIG. Also in this case, the both step portions 16, 1
7 can be engaged with each other to prevent rainwater from entering. It should be noted that the first step portion 16 and the second step portion 17 may be engaged with each other to prevent rainwater from entering, or if the invaded rainwater can be drained in a desired direction, It may have a shape.

Further, in the illustrated embodiment, the floor plate 12
An embossed pattern 18 for preventing slip is formed on the upper surface side, and a water blocking rib 19 is provided on the lower surface side. The covering layer 15 for covering the core material 14 is set to have a thickness on the upper side of the core material 14 thicker than a thickness on the lower side of the core material 14 so that the core material 14 is not thinned during walking. The cushioning property of is improved. Specifically, for example, the thickness of the core material 14 is 3.2 mm, the thickness of the coating layer 15 on the upper side is 2.8 mm, the thickness on the lower side is 1.5 mm, and the total thickness is 7.5 mm.
It is a degree.

On the other hand, in the joint floor plate 12 'used for the joint portion of the floor material unit 8, as shown in FIG. 7, an opening 21 is formed at one end of the core material 14 so that the vertical gutter 20 can be inserted therethrough. It is provided. Further, the synthetic rubber coating layer 15 that coats the core material 14 is provided with a cutting portion 22 at a position corresponding to the opening portion 21 so that an insertion portion capable of communicating the upper and lower sides of the floor plate 12 can be opened.

In the embodiment shown in FIG. 8, the cutting portion 22 is formed by thinning the thickness of the portion corresponding to the opening 21, which facilitates cutting of the thinned portion. . In the embodiment shown in FIG. 8, a concave portion is formed on the back surface side to reduce the wall thickness, and the upper surface is formed flat so that the cutting portion 22 is not noticed.

On the other hand, in the embodiment shown in FIG. 9, a V groove 23 is formed in the coating layer 15 on the lower surface side as the cutting portion 22,
By inserting a knife along the V groove 23, the insertion portion corresponding to the vertical gutter 20 to be inserted can be easily opened. That is, a plurality of V-grooves 23 are formed in concentric circles or substantially squares corresponding to the cross-sectional shape of the downspout 20, and the V-grooves 23 corresponding to the size and shape of the downspout 20 to be inserted are selected. If cut off, a gutter insertion part that fits the gutter 20 can be opened. For example, the square gutter shown in FIG.
When passing as 0, the standard size of the square gutter is 65 mm.
When the corner V groove 23 is prepared and the circular gutter shown in FIG. 10 (B) is passed as the vertical gutter 20, the V groove 23 having a diameter of 50 mm and a diameter of 60 mm which are standard dimensions of the circular gutter is prepared. 65
50mm and 60mm round V inside the square V groove 23 mm
If the grooves 23 are formed concentrically, they can be appropriately selected according to the size and shape of the downspout 20 used at the site. Further, in the embodiment shown in FIG. 9, the V-groove 23 is formed on the back surface of the floor plate 12, but since the installation work of the downspout 20 is generally performed after the assembly work of the outer corridor is completed, it is formed on the front surface (upper surface). It is easier to perform the excision work.

Next, a method of constructing the outer corridor 1 as described above will be described. First, together with the foundation work, the support girder 4 is attached to the joint bracket 24 provided on the side wall 3 of the building with the bolt B in a substantially horizontal direction. Although not shown, a backup material is attached to the upper part of the receiving girder 4.

At the end of the outer corridor 1, the girder 4 and the girder 25
Is attached by a bolt B, and a prism 26 is erected on the tip side of the girder 25 as a kind of column member 6. In addition, a plurality of middle pillars 27 are erected as a kind of pillar material 6 at predetermined intervals between the prisms 26. Furthermore, the front girder 5 is placed between each of the above pillars.
And a joist 7 is installed between the receiving girder 4 and the front girder 5 to form a shaft assembly. In addition, joists 7 are floor material units 8
Since the main purpose is to keep the distance between the receiving girder 4 and the front girder 5 at a predetermined length until the installation of
It does not necessarily have to be provided. This is because, after the floor material unit 8 is laid, the frame material 11 functions as a conventional joist. However, as described above, if the joists 7 are provided, it is easy to maintain the distance between the receiving girder 4 and the front girder 5 at a predetermined length.
It is easy to lay the floor unit 8.

When the joist 7 is attached, normally, FIG.
As shown in (A) and (B), a plate-shaped attachment piece 28 formed at the tip of the joist 7 is attached to the attachment portion 4a of the receiving girder 4 and fastened with bolts B and nuts N. In addition, bolts B and nuts N are similarly fastened to the side of the center pillar 27.

On the other hand, in the portion through which the vertical gutter 20 passes, as shown in FIGS. 3C and 3D, a U-shaped fastening piece 29 is attached to the tip of the joist 7 so as to join the receiving beam 4. The fastening piece 29 is formed on the mounting portion 4a of the receiving girder 4, and the bolt B,
The vertical gutter insertion space 30 through which the vertical gutter 20 is passed is formed by tightening with the nut N. The bolts B and nuts N are used to fasten the center pillar 27 as in the case of the normal joist 7. When the joist 7 is not provided, the vertical gutter insertion space 30 may be formed by using the independent fastening piece 29.

Next, the flooring unit 8 is laid on the steel frame structure assembled as described above. At this time, the floor material unit 8 used for the outer corridor 1 according to the present invention is provided with a plurality of floor plates 12.
Is attached to the frame material 11 in advance at the factory. Therefore, the weight of the floor material unit 8 is considerably heavier than that of the single floor plate 12, and the operator cannot easily lift it by hand. However, in the flooring unit 8 according to the present invention, the mounting space 13 where the suspending tool can be mounted at both ends.
Is left. Therefore, as a suspending tool, for example, as a suspending tool, the mounting empty portion 13, that is, the portion where the horizontal member 10 and the vertical member 9 and the auxiliary horizontal member 10a and the auxiliary vertical member 9a that form the frame member 11 to which the floor plate 12 is not attached is exposed. The nylon sling 31 and the wire rope can be passed through and lifted by a tow truck.

Then, the floor material unit 8 lifted by a tow truck is lowered at a predetermined position and fixed to the receiving beam 4 and the front beam 5 with bolts B. Although not shown, it is advisable to connect the auxiliary vertical members 9a of the adjacent floor material units 8 with the joist 7 in between.

A joint frame 32 is attached to the connecting portion of the floor material unit 8. This joint frame 32 is
A rectangular standard joint frame 32 to be attached to a normal connecting part
a and a vertical gutter mounting joint frame 32b which is mounted at a position where the vertical gutter 20 is inserted and whose one end is open.

Then, the floorboard 1 is provided on a portion of the flooring unit 8 where the floorboard 12 is not attached and on the upper surface of the joint frame 32.
2 is laid, the mounting holes (not shown) of the floor material unit 8 and the joint frame 32 and the fastening holes 33 of the floor plate 12 are made to communicate with each other, and they are fastened in series by screws. A screw cap (not shown) is attached to the head of the screw to seal it.

As described above, at the construction site, the floor plate 12 attached to the mounting space 13 of the floor material unit 8 is the same as the floor plate 12 previously fixed to the floor material unit 8. The floor plate 12 has a length of about 1350 mm and a width of about 455 mm, for example. Also, a joint floor plate 1 used for the joint section
2 ', that is, the floor plate 12 attached to the joint frame 32 is formed to have a half width (227.5 mm) of the normal floor plate 12 described above. In the core material 14 of the floor plate 12 'for joints,
As described above, the opening 21 is opened and the cut portion 22 is formed in the coating layer 15. Therefore, downspout 2
When arranging at a position where 0 passes, at the construction site,
The cutting part 22 corresponding to the downspout 20 is cut off with a cutter to form a downspout insertion part.

The joint floor plate 12 'has no difference in appearance except that the width thereof is half that of the ordinary floor plate 12, so that the joint floor plate 12' can be used for other joint portions. However, a joint floor plate using the core material 14 without the opening 21 may be prepared separately for a standard joint.

On the other hand, the staircase unit 35 is appropriately connected to one side of the outer corridor 1. Then, after adjusting the right angle and the water gradient as shown in each part, the bolts B fastening each part are finally tightened.
In addition, the gutter 20 is attached and the vertical gutter 20 is inserted into the vertical gutter insertion portion cut by the cutter as described above. Since the cover layer 15 is made of rubber at the opening edge of the vertical gutter insertion portion, if the cutting is appropriate with a cutter, the elasticity of the rubber causes the opening edge to adhere to the outer peripheral surface of the vertical gutter 20. For example, caulking material may be filled.

According to the prefabricated outer corridor 1 of the present invention having the above-described structure, the floor material unit 8 is left with the mounting space 13 and a plurality of floor plates 12 are previously attached to the other portions. Therefore, the number of man-hours on the site, particularly the work of fixing the floor plate, is significantly reduced, which can significantly reduce the construction time.

Further, since there is provided the mounting empty portion 13 in which the suspending tool including the sling 31 and the like can be mounted, even if the weight of the flooring unit 8 is increased, it can be suspended by the wrecker, which hinders the work. Not only is there no reduction, but labor can be reduced.

Further, the vertical gutter 20 can be arranged even in the middle of the outer corridor 1, and the inclination of the rain gutter can be optimally set even in the long outer corridor 1. Moreover, the vertical gutter insertion portion for inserting the vertical gutter 20 can be opened very easily by the cutter. It should be noted that not only the downspout 20 but also a member such as a gas pipe or a water pipe arranged outside the building can be inserted through the downspout insertion portion.

Although the present invention has been described above with reference to the illustrated embodiments, the present invention is not limited to the above-described embodiments, and can be appropriately implemented without departing from the configuration described in the claims.

[0035]

As described above, according to the present invention, since a plurality of floor boards are attached to the frame material in advance to form the floor material unit, the number of man-hours at the site is significantly reduced and the construction time is reduced. Can be significantly shortened. Also, the work of preliminarily attaching a plurality of floor boards to the frame material can be performed by a flow work in a factory where the working environment is far better than that of the construction site, so it is significantly more efficient than in the case of the construction site. It can be performed, and it is not necessary to work at a high position like a construction site, so safety can be improved. Further, even if the weight of the floor material unit is increased, it can be suspended by the wrecker using the mounting empty portion, so that not only the work is not hindered, but also the labor can be reduced.
