Further, in the illustrated embodiment, an embossed pattern 18 for preventing slip is formed on almost the entire upper surface, and a rib 19 for stopping water is provided on the lower surface.
The covering layer 15 that covers the core material 14 is designed such that the thickness of the upper side of the core material 14 is set to be greater than the thickness of the lower side of the core material 14 so that the core material 14 can be used for walking without thinning. The cushioning is enhanced. Specifically, for example, the thickness of the core material 14 is 3.2 mm, and the thickness of the covering layer 15 on the upper side is 2.8.
mm, the thickness on the lower side is 1.5 mm, and the overall thickness is about 7.5 mm.

On the other hand, in the joint floor plate 12 'according to the present invention used for the joint portion of the floor material unit 8,
As shown in FIG. 7, an opening 21 is provided at one end of the core member 14 so that the downspout 20 can be inserted therethrough. Further, the synthetic rubber covering layer 15 covering the core material 14 from above and below including the opening 21 to cover the entirety, and covers the opening 21, that is, the position corresponding to the opening 21. The cut-off portion 22 is cut off from the covering layer 15, and the cut-off portion 22 is cut off so that the floor plate 12 can pass through the opening 21 in the upper and lower directions.

In the embodiment shown in FIG. 8, the cut portion 22 is formed by forming a concave portion on the back surface side of a portion corresponding to the opening portion 21 to reduce the thickness, and the cut portion 22 is made thin. Facilitating resection of parts. In addition, the cutting part 2
The upper surface side of 2 is flat like the other upper surface portions so that the pedestrian is not conscious of the cut portion 22.

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 of the cut portion 22, and a knife is inserted along the V-groove 23 so that the downpipe 20 to be inserted can be inserted. Is formed so that the insertion portion corresponding to the above can be easily formed. That is, a plurality of V-grooves 23 corresponding to the outer shape or cross-sectional shape of a pipe material generally used as the downspout 20 are formed concentrically, and V-shaped grooves corresponding to the size and shape of the downspout 20 to be inserted are formed. If the groove 23 is selected and cut off, the downspout 2
A downpipe insertion section suitable for 0 can be opened. For example, FIG.
When the square gutter shown in FIG.
When the corner V-groove 23 is formed and cut at the site by a cutter along the V-groove 23 and the round gutter shown in FIG. A V groove 23 having a diameter of 50 mm and a diameter of 60 mm is prepared.

As shown in FIG. 11, round V-shaped grooves 23 having a diameter of 50 mm and 60 mm are formed concentrically inside a V-shaped groove 23 having a square shape of 65 mm (substantially square in section with a curved surface). If so, it can be appropriately selected according to the size and shape of the downspout 20 used at the site. In this case, each V
The position of the center of the groove 23 is the center through which the downspout 20 passes, and is standardized in advance with respect to the positional relationship with the pillar 6. Further, in the embodiment shown in FIG. 9, the V-groove 23 is formed on the back surface of the floor plate 12 '. However, since the installation work of the downspout 20 is generally performed after the outer corridor is completed, the surface (upper surface) is formed. It is easier to perform the excision work if it is formed.

When the groove 23 has a V-shaped cross section as shown in FIG. 13, the cutter blade is guided to the deepest portion of the groove 23, so that it is easy to cut along the groove 23. The cross-sectional shape of 23 is not limited to this,
For example, the section may be substantially U-shaped. Groove 23 of any cross-sectional shape
However, an inclined surface is formed outside the deepest part of the groove 23, and the dimension at the deepest part is the same as or slightly smaller than the dimension of the pipe material of the downspout 20 (the diameters of 50 mm, 60 mm, and 65 mm square). When the downpipe insertion section is set, a thin-walled deformed section having an inclined surface is formed in the rubber coating layer at the opening edge, and the inner peripheral edge of the thin-walled deformed section is elastically pressed against the downpipe 20 and securely adheres. It is desirable to be configured to be able to do so.
In addition, when the thin-walled deformed portion is formed, the portion having the normal thickness is cut vertically, and it is easy to deform by the portion thinner than the opening edge when the vertical gutter insertion portion is opened. It is easy to reliably press against the outer peripheral surface of the base.

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

At the end of the outer corridor 1, the girder 4 and the girder 25
Is attached by bolts B, and a prism 26 is erected on the tip end side of the girder 25 as a kind of the pillar 6. Further, a plurality of middle pillars 27 are erected between the prisms 26 at a predetermined interval standardized in advance as a kind of the pillar material 6. In addition, the front spar 5
And a joist 7 is erected between the receiving girder 4 and the front girder 5 to form a shaft assembly.

When the joist 7 is attached, usually, as shown in FIG.
As shown in (A) and (B), a plate-like mounting piece 28 formed at the tip of the joist 7 is attached to the mounting portion 4a of the receiving girder 4 and fastened with bolts B and nuts N. The center column 27 is similarly fastened with bolts B and nuts N.

On the other hand, in the portion where the downspout 20 passes (the standing position of the column member 6), as shown in FIGS. 3 (C) and 3 (D), A U-shaped fastening piece 29 is formed, and this fastening piece 29 is attached to the mounting portion 4 of the girder 4.
The vertical gutter insertion space 30 through which the vertical gutter 20 is passed is formed by tightening with the bolt B and the nut N in addition to a. Then, the center pillar 27 and the fastening are fastened by bolts B and nuts N in the same manner as the above-mentioned ordinary joists 7. When the joist 7 is not provided, the downspout insertion space 30 may be formed by using the independent fastening piece 29.

Next, the floor unit 8 is laid on the steel frame structure assembled as described above. At this time, the floor material unit 8 has a plurality of standard floor boards 12 attached to the frame material 11 in advance. Therefore, the weight of the floor unit 8 is considerably heavier than that of the single standard floor panel 12, and cannot be easily lifted by an operator. However, the flooring unit 8 has mounting cavities 13 at both ends where mounts can be mounted. Therefore, this mounting space 1
3, that is, a portion where the horizontal member 10 and the vertical member 9 and the auxiliary horizontal member 10a and the auxiliary vertical member 9a constituting the frame member 11 on which the standard floor panel 12 is not stuck are exposed, for example, a nylon sling 31 or a wire as a suspension tool. It can be hung with a tow through a rope.

Then, the floor material unit 8 suspended by a tow is lowered at a predetermined position, and is fixed to the receiving girder 4 and the front girder 5 with bolts B. Although not shown, the auxiliary vertical members 9a of the adjacent floor material units 8 may be connected with the joists 7 interposed therebetween.

Further, a joint frame 32 is attached to a connection portion of the floor unit 8. This joint frame 32
A rectangular standard joint frame 32 to be attached to a normal connection part
a and a vertical gutter mounting joint frame 32b which is mounted at a position where the vertical gutter 20 is inserted and which has an open end.

Then, the standard floor plate 12 and the joint floor plate 12 'according to the present invention are laid on the portion of the floor material unit 8 where the standard floor plate 12 is not stuck and on the upper surface of the joint frame 32. The fixing holes 32 (not shown) of 32 and the fixing holes 33 of both floor plates 12, 12 'are communicated with each other and are fixed in series with screws. A screw cap (not shown) is attached to the head of the screw and sealed.

As described above, at the construction site, the standard floor plate 12 attached to the mounting space 13 of the floor material unit 8 is the same as the standard floor plate 12 fixed to the floor material unit 8 in advance. This standard floor panel 12 has a length of 1350 mm and a width of 4 mm, for example.
It is about 55 mm. Also, the joint floor plate 12 'used in the joint portion, that is, the joint floor plate 12' to which the present invention is applied, which is attached to the joint frame 32, is formed to be approximately half the width (227.5 mm) of the ordinary standard floor plate 12. It is. An opening 21 is formed in the core member 14 of the joint floor plate 12 'as described above, and the opening 2
The cut portion 22 is formed in the coating layer 15 corresponding to No. 1.
Therefore, the joint floor plate 12 ′ according to the present invention is
When arranging in a position where the downspout 20 passes, if the end on which the cutting portion 22 is formed is directed toward the side wall of the building, the cutting section corresponding to the downspout 20 is installed at the construction site. By cutting off 22 using a cutter, the downspout insertion portion can be formed very easily.

It should be noted that the joint floor plate 12 'has a width that is half that of the normal standard floor plate 12.
Since there is no noticeable difference in appearance, it can be used for other joints. Even when the V-groove 23 is formed on the upper surface of the floor plate, the position is the end of the floor plate 12 'and the shape of the V-groove 23 is circular or substantially square and looks like a pattern. Never.

On the other hand, the staircase unit 35 is appropriately connected to one side of the outer corridor 1. After adjusting the right angle and the water gradient as in each part, the bolts B fixing the respective parts are fully tightened.
In addition, a gutter is attached, and the vertical gutter 20 is inserted into the vertical gutter insertion portion of the joint floor plate 12 ′ according to the present invention, which can be formed by cutting off the vertical gutter 20 with the cutter as described above. Since the coating layer 15 is made of rubber at the opening edge of the downspout, the opening edge is in close contact with the outer peripheral surface of the downspout 20 due to the elasticity of the rubber, and a gap is hardly formed between the two. Therefore, if the opening edge of the downspout insertion portion is in close contact with the outer peripheral surface of the downspout 20, the appearance is good and there is no need to fill the gap with a caulking material.

According to the joint floor panel 12 'according to the present invention having the above-described structure, the downspout 20 can be disposed even in the middle of the outer corridor 1, and even if the outer corridor 1 is long, the downspout 20 can be rained. The inclination of the gutter can be set optimally. Moreover, the downspout insertion portion for inserting the downspout 20 can be opened very easily by a direct cutter without drawing a marking line, and the practical value is extremely high. In addition, the downspout 2
Not only 0 but also a member provided outside the building, such as a gas pipe or a water pipe, can be inserted.

Although the present invention has been described with reference to the illustrated embodiment, the present invention is not limited to the above-described embodiment, and can be appropriately implemented without departing from the configuration described in the claims. For example, in the illustrated embodiment shown in the drawings, the floor plate of the present invention is applied to a joint portion of a floor material unit in which a floor plate is previously attached to a frame material, but the floor plate according to the present invention includes a receiving girder. The present invention is also applicable to an external corridor in which a floor panel is individually provided between the front girder. In this case,
The arrangement position of the downspout can be set more freely. The opening may be formed only at one end of the core material as in the above-described embodiment, or may be formed at both ends. If openings are formed at both ends and cut portions are formed at both ends in this manner, directionality is reduced at the time of laying, and work becomes easier.

[0035]

As described above, the present invention is a floor plate in which a metal core material is covered with a rubber covering layer, so that footsteps of pedestrians are not affected, and the present invention is silent. Since the opening was provided and the cut portion was formed in the coating layer at a position corresponding to the opening, the rubber cut portion was cut off with a cutter to connect the floor material vertically with the core material opening. Notches can be easily opened. Therefore, even in the case of a floor plate having a metal core material, it is possible to extremely easily open the downspout insertion portion for inserting the downspout, and the labor and time for attaching the downspout can be remarkably reduced. According to the second aspect of the present invention, the cut section is thinned, so that the downpipe insertion section can be more easily opened. According to the third aspect of the invention, since the cutting position is indicated by the groove, the preparation work for drawing the marking line by measuring the size is not required, and the downspout insertion portion is accurately positioned by the direct cutter. Since the opening of the opened downspout can be formed with the correct shape and dimensions, and the opened edge is made of rubber, the elasticity of the rubber makes the opening edge easily adhere to the downspout, and a gap is hardly generated.
