Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a corridor attached to a large-scale building, and more specifically, it is mainly used for worker's movement (personal movement) for maintenance and inspection of the building inside and outside the building. Concerning the corridor structure

[0002]

[Prior art]

 In many cases, large-scale buildings are usually provided with walkways (walking walkways) that allow workers to come and go to various parts inside and outside the building for maintenance and inspection.

For example, in a factory or the like, cooling towers are provided for cooling factory water, air (gas), and the like. When these cooling towers also have a large capacity, workers are placed inside and outside the cooling tower. There is a walkway for people to come and go.

As described above, installation of a corridor attached to a large-scale building is subject to various restrictions. Generally, the structure is manually constructed in accordance with the corridor installation space set in the building. The installation method of assembling is adopted. In addition, this type of corridor is used by a specific person (worker) and is used relatively infrequently. In many cases, however, the number of parts is reduced as much as possible by using many commercially available general-purpose parts.

FIG. 3 is a partial perspective view of a conventional walkway structure.

In the figure, reference numeral 1 indicates a corridor attached to a building. In this corridor 1, a pair of left and right base bodies 2 are fixed in parallel at a predetermined interval, a floor material 3 is attached in a bridging manner between the left and right base bodies 2, and both base bodies 2 are provided with a predetermined base. The fence 4 is erected at a height, and the toe plate 5 is attached to the fence 4 separately from the base body 2 at a predetermined height from the floor material 3.

Commercially available chevron steel is used for the base body 2. One plate portion of the base body 2 (chevron steel) is oriented horizontally to form a horizontal plate portion 2a, and the other plate portion is oriented downward from the horizontal plate portion 2a. Vertical plates 2b are hung down, the left and right bases 2 are fixed on the beams 2c, and both side edges of the floor material 3 made of a checker plate or expanded metal are fixed on the horizontal plates 2a by a suitable stopper or the like. Is attached using. The fence 4 is composed of a commercially available steel pipe having an appropriate thickness, and the vertical rods 2a of the base 2 are provided with the supporting rods 4a at appropriate intervals. The horizontal rods 4b parallel to the book are installed. In addition, the toe plate 5 is a member that slips on the floor material 3 so that the toes (foot) do not come out when workers move in and out of the corridor 1. There is no limitation in terms of morphology, Generally, a member like a flat bar is used, and it is attached to the inside of the support rod 4a so as to be positioned above both side edges of the floor material 3.

[0008]

[Problems to be solved by the device]

 As described above, in the case of the conventional corridor structure in which the commercially available chevron steel is used for the base 2 forming the corridor, one floor plate 2a to which the flooring 3 is attached is attached to the other vertical plate portion 2b. Since the left and right bases 2 are fixed to the beam 2c, the beam 2c is provided with notches 2d for dropping the vertical plate portions 2b at both ends thereof, as shown in FIG. Needs cutting work such as. This makes the work complicated. In addition, a toe plate 5 is separately attached to the fence 4 in order to prevent the toes (foot) from coming out when workers go back and forth in the corridor 1. This is a fence structure. Complicates and affects the installation cost of the corridor.

The present invention has been made in view of the above points, and a cutting work for fixing the base to the beam is performed on the base forming the walkway while using commercially available angle steel. It is an object of the present invention to provide a walkway structure that does not require it, and that the base body itself exerts a toe plate function to simplify the structure.

[0010]

[Means for Solving the Problems] A first configuration of the present invention for achieving the above object is attached to a large-scale building, and is mainly used for maintenance and inspection of the building. In a corridor used for, a vertical plate that has two narrow and long plate parts that are connected at right angles, one plate part is oriented horizontally and the other plate part stands up from the horizontal plate part. And a pair of left and right bases fixed in parallel opposite to each other at a predetermined interval, and a flooring with both side edges attached to the base in a bridging manner between the left and right bases. It is a corridor structure.

The second structure is a corridor structure characterized in that chevron steel is used for the base body in the first structure, and the left and right base bodies are horizontally fixed on the beam.

A third structure is a walkway structure in which a fence is erected at a predetermined height with respect to the left and right base bodies in the first structure or the second structure.

[0013]

[Action]

 Since the base body is configured such that the other vertical plate portion stands up with respect to the horizontal plate portion to which the floor material is attached, it is possible to easily fix the left and right base bodies horizontally on the beam.

Since the vertical plate portion of the base body rises from both side edge portions of the floor material at a predetermined height and functions as a toe plate, the walkway structure can be simplified.

[0015]

【Example】

 An embodiment of the walkway structure according to the present invention will be described below.

FIG. 1 is a partial perspective view of a walkway structure showing an embodiment of the present invention.

It should be noted that the same or similar portions as those in FIG.

As a corridor 1 installed in a building, a pair of left and right bases 2 are fixed in parallel to a beam 2c at predetermined intervals, and a floor material 3 is attached in a bridging manner between the left and right bases 2. ing.

A commercially available chevron steel is used for the base body 2, one plate portion of which is oriented horizontally to form a horizontal plate portion 2a, and the other plate portion is formed of a vertical plate portion 2b which stands up from the horizontal plate portion 2a.

The floor material 3 is attached to the base body 2 inside the vertical plate portion 2b of the base body 2 with respect to the horizontal plate portion 2a, and when the left and right base bodies 2 are fixed to the beam 2c, 2 is laid horizontally on the beam 2c and the flat lower surface 2a of the flat plate 2a is brought into contact with the surface of the beam 2c and directly fixed by welding or the like, or fixed by using an appropriate stopper. .

In the case of the corridor 1 with a fence, as shown in FIG. 2, the fence 4 is erected at a predetermined height with respect to the left and right base bodies 2. The fence 4 is composed of a steel pipe or the like.

[0022]

[Effect of device]

 As described above, according to the present invention, commercially available chevron steel is used for the base body that constitutes the corridor, and one vertical plate portion on which the floor material is attached is raised against the other horizontal plate portion. Therefore, to fix the left and right bases to the beam, it is possible to easily fix the bases by placing them horizontally on the beam without the need for cutting the beam as in the conventional case, and to significantly reduce the corridor assembly time. In addition, the vertical plate part of the base body that rises from both edges of the floor material functions as a toe plate that prevents workers from slipping on the floor surface and keeping their toes (foot) out when workers walk up and down the corridor. The toe plate that is separately attached to the fence can be omitted as in the past, and the structure can be simplified and the number of parts can be reduced compared to the conventional corridor structure, and the cost can be provided at low cost. In addition, the base and beam are fixed to each other by making flat surfaces of the horizontal plate of the base and the beam surface contact each other so that the base and the beam are fixed back to back. For this reason, plating (hot dip galvanizing) does not require special holes for plating, and plating work can be done easily. In addition, when fixing the corridor to the building when installing the corridor in the building, place the lower surface of the horizontal plate of the base directly on the flat installation surface on the building side, and install appropriate bolts. Since it can be fixed using the fasteners of the above, it does not require a fixing gusset plate or the like provided on the building side, and the number of fasteners can be reduced, and workability can be significantly improved.
