Similarly, a new stepped floor unit structure is successively built adjacent to the stepped floor unit structure to complete the stepped floor on the entire foundation surface portion 2 in the hall.
A desk, a chair, a chair for a passenger seat, and the like are installed on each tread of the stepped floor structure.
The widths of the corrugated floor units of each corrugated floor unit structure are preferably basically the same from the materials, etc., but depending on the situation at the site, corrugated floors of corrugated floor unit structures of different widths may be constructed side by side. Also, the front and rear length of each stepped floor unit structure varies depending on the shape of the base surface portion and the like.

  The above-mentioned corrugated floor structure can be constructed in unit units (corrugated floor unit structure). However, depending on the convenience of construction, the work may proceed simultaneously with other corrugated floors. Laying of the stepping plate, the kicking plate, the finishing material, etc. may be performed integrally with the stepped floors of the plurality of stepped floor unit structures (laying over both).

Therefore, according to the first embodiment, each member is produced at the factory, and the step floor can be configured by assembling these members at the site, so that the productivity and economy are excellent, and the step floor is unitized. Work efficiency can be improved. Further, according to the above-mentioned corrugated floor, since each member is made compact and each member is assembled mainly using screws on site, the work can be performed quickly and easily and the workability is excellent.
In addition, the above-mentioned corrugated floors can be maintained in units as a unit, so that workability is good, and maintenance such as renewal can be easily performed. Even when a part of the entire corrugated floor structure is composed of other structures (for example, entrances and exits), the corrugated floor of the appropriate corrugated floor unit structure can be formed on the front, rear, left and right, and the form of the hole, etc. Can be flexibly adapted.

Next, a second embodiment will be described. Note that the same members and the like used in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted here.
FIGS. 12A and 12B show the kick members 150 and 151 according to the second embodiment.
The kick members 150 and 151 have a shape (one set) in which the portions of the kick plate portions are divided into upper and lower parts, and the upper side includes upper kick members 152 and 153 and the lower side includes lower kick members 154 and 155. . Each of these kicking materials is obtained by bending a rectangular steel plate.

The upper kick member 152 of the kick member 150 shown in FIG. 12A is a flat horizontal upper plate portion 156 and has an acute angle downward from the front portion of the upper plate portion 156 (for example, 80 degrees to 85 degrees). The upper kick plate portion 158 is bent. In addition, a downward flange piece 160 is formed at the rear end of the upper plate portion 156, and a plurality of screw holes 162 are provided in the lateral direction near the lower portion of the upper kick plate portion 158.
The lower kick material 154 has the same inclination angle shape as the upper kick plate portion 158 and is parallel to the upper kick plate portion 158 (for example, the plate surfaces of the two kick plate portions 158 and 164 are parallel to each other, or A lower kick plate portion 164 arranged in a state in which the two kick plate portions do not cross each other), and a flat horizontal lower plate portion 166 that is bent forward from the lower portion of the lower kick plate portion 164 Have Further, a downward support piece 168 is formed at the front end of the lower plate portion 166.

In addition, a downward support piece 178 is formed at the front end of the lower plate portion 176, and a plurality of screw holes 175 (for example, four locations) are provided vertically on the lower side of the lower kick plate portion 174.
Usually, the kicking plate portions of the upper kicking material 153 and the lower kicking material 155 are used in a form separated by a predetermined distance. For this reason, the upper kick material 153 and the lower kick material 155 are separated from each other in the vertical direction, and can be freely applied to the height of the kick depending on the degree of the clearance, and the member shape can be unified. I can plan.

In this way, by dividing the kicking material into an upper kicking material and a lower kicking material (one set), regardless of the height of the kicking, it can be used for any height kicking. It can be applied, and it is possible to construct various heights of kick with only one set of kick materials. Moreover, in the case of the aspect which left the upper kick material and the lower kick material, the material of the kick board part can be reduced and there exists an economical effect.
Further, the set of kick members 150 has a shape in which the angle formed by the upper plate portion (or lower plate portion) and the upper (or lower) kick plate portion is an acute angle or a right angle. It can be used properly by etc. The set of kick members 150 and 151 is attached to the upper portion of the receiving beam member 6 as in the case of the integral kick member 10 and forms the foundation of the tread surface of each step of the step floor.
In addition, the basic construction form and construction method of the set of kicking materials 150 and 151 are the same as those of the integral kicking material 10.

By this fixing member 200, the standing of the bundle member 8 using the hinge 190 with respect to the receiving member 6 is reinforced.

FIG. 16 shows a main part of a stepped floor unit structure (stepped floor structure) according to the second embodiment. In addition, regarding the stepped floor unit structure here, the place of adoption, the overall form, the construction method, etc. are substantially the same as in the first embodiment, and the same reference numerals are used for the same members, etc. The detailed description in is omitted.
In this stepped floor unit structure, as the member forming the base of the tread surface 13, the above-described vertically divided kick material 150, hinge 190, and the like are used.

Here, the bundle member 8 has the lower portion of the pipe portion 62 projecting into the inside from the opening portion 61 of the receiving beam material 6 and the lower end portion thereof is applied to the bottom plate portion 56 of the receiving beam material 6 or arranged in the vicinity thereof. Stand the bundle 8.
Then, a hinge 190 is arranged at a location where the lower part of the rear side of the bundle 8 and the upper part of the receiving beam 6 intersect, and the plate piece 192 of the hinge 190 is attached to the upper plate of the receiving beam 6 using the screw 105. It fixes to the one part 60,60. When the other plate piece 192 is not fixed to the bundle member 8 in advance, the plate piece 192 is similarly fixed to the side surface portion of the pipe portion 62 of the bundle member 8 using the screw 105.
Thus, the bundle member 8 is held so as to be pivotable in the front-rear direction with respect to the receiving beam member 6. At this time, the angle of the bundle member 8 with respect to the receiving beam member 6 is adjusted, and the bundle member 8 is erected accurately (vertically) (using the frictional force of the hinge 190, etc.).

Further, a fixing member 200 is used at a location where the lower part of the front side of the bundle member 8 and the upper part of the receiving beam member 6 intersect. The lower part of the fixing member 200 is inserted from the opening 61 of the receiving beam member 6, and the left and right engaging recesses 202, 202 are fitted into the upper plate pieces 60, 60 formed inwardly projecting, respectively. Then, the bundle member 8 is held vertically, the screw 105 is screwed into the screw hole 204 of the fixing member 200, and the upper portion of the fixing member 200 is fixed to the pipe portion 62 of the bundle member 8. In this state, the forward and backward rotation of the bundle member 8 is fixed, and the bundle member 8 is erected vertically above the inclined receiving beam member 6.
In the state where the bundle material 8 is erected temporarily with a hinge 190 and a kick material, a tread board, etc. are applied to the upper portion of the bundle material 8, the bundle material 8 can be maintained upright only with the hinge 190. . That is, the load applied to the bundle material 8 is mainly in the vertical direction, and even if a lateral force is applied, this is held by a tread plate or the like and the standing state of the bundle material 8 is maintained. For this reason, the fixing member 200 is used as an auxiliary to reinforce the standing fixing of the bundle member 8. In this case, it is effective to use a hinge that is hard to open and close.
