[Industrial applications]

 The present invention is used for new building construction, remodeling construction, building management, ceiling plumbing, lining, interior wall construction, stair work, maintenance work, etc., and also for venue construction, stage construction, etc. The present invention relates to a work floor unit in which a handrail is mounted on a horizontal member.

[0002]

[Prior art]

 Conventionally, handrail members are installed on the temporary work floor in order to prevent a fall disaster. The handrail member is known as a fixed type, an insertion type, or a suspension drawer type.

[0003]

[Problems to be solved by the device]

 However, the fixed type is inconvenient to work and is inconvenient to stack in the material storage area. The plug-in type has a relationship between the main body and parts, so it is inconvenient to manage those sets, and the suspension pull-out type ensures the height enough to hang down from the work floor level. Since it must be, it was disadvantageous from the viewpoint of space saving. Therefore, the present invention focuses on the horizontal material (horizontal structural material) that originally constitutes the temporary work floor, and constructs a handrail on the horizontal work material to integrate it into and out of the temporary work floor. It is an object of the present invention to provide a working floor unit in which a handrail is mounted on a horizontal member that is capable of space saving.

[0004]

[Means for Solving the Problems]

 Place the handrail horizontally to save space, and when the handrail is actually used, the handrail will be in an upright position. A sliding hinge mechanism is used so that changes can be made. In other words, two horizontal rail-shaped members of the ripped channel steel are provided facing each other, and two pairs of horizontal rail members, one pair of these horizontal rail members, are stacked and assembled into a cross girder. The cotter is hung between the lips of the horizontal member to allow the handrail to slide in and out in the axial direction of the horizontal member. A stopper is provided to prevent the cotter from slipping out, and a cutout that is large enough to accommodate the handrail is provided on the upper surface of the horizontal member, and the end opening of the handrail and the end of another handrail are provided. An attempt is made to provide a work floor unit in which a handrail is mounted on a horizontal material, which is characterized in that a handrail is laid across the mouth and fixed, and a work floor is attached on the horizontal material assembled in the girder. It is a thing.

The small face is a side face perpendicular to the material axis of a long product, and the lip groove steel is a kind of light weight steel. The double digit is a word that refers to a curly tree that is in the shape of a well or something that is in the shape of a well. The beams and girders, which are structural materials, may be made of lip grooved steel, and this may be used as is as a horizontal member for accommodating the handrail. There is no limitation to the shape like the lip channel steel described above as long as the handrail can be slid in and out of the horizontal member.For example, a double pipe is made by combining pipe members and the inner pipe is It may be applied to the handrail. Alternatively, a hanger rail on which the handrail is suspended may be assembled to the cross girder, and the hanger rail may be hung vertically on the back surface of the floorboard (see FIG. 18). The examples described below disclose girders and beams made of lip channel steel. When a pair of beams or girders facing each other is installed so that handrails can be taken in and out of each beam or girder from both sides, up to four handrails can be installed on the work floor. If it is sufficient to install one or two handrails, it is possible to simply apply the mechanism according to the present invention to the conventional arrangement of girders and beams without further stacking girders and beams to form a double girder. Conceivable. For the main and end openings, the thick wood end of the log is called the main opening and the tip end of the log is called the end opening.In the present invention, a handrail is inserted into the girder or beam made of lip channel steel. In this case, the end of the handrail that goes into the back is called the opening, and the front is the end. A lip is two small pieces that are opposed to each other and are bent inwardly formed in a lip channel steel. The cotter is one component that constitutes the joint, but in the present invention, it refers to the protruding rod attached to the shaft and is referred to as the cotter.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a girder (1) and a handrail (2) separately. The girder (1) is lip channel steel as shown in the enlarged sectional view taken along the line AA. In the AA line enlarged sectional view, (3) is a lid and (4) is a lip. In FIG. 1, (5) is a notch, (2) is a handrail, (6) is a handrail, and (7) is a cotter. Although only one handrail frame (referred to as the whole handrail (2) and handrail (6) combined) is shown in FIG. 1, notches are provided at both ends of the girder (1). It can be easily inferred that the handrail frame can be inserted from both sides of the girder (1) since the part (5) and the like are described. FIG. 2 is a perspective view showing a state in which the handrail frame is assembled on the girder (1). The gap between the lips (4) is set narrower than the width of the handrail (2). The crossover length of the cotter (7) is set slightly shorter than the internal dimensions of the lip channel steel.

FIG. 4 is an embodiment showing a state in which the girder (1) and the beam (8) are assembled in a cross girder. Installing the lid (3), the lip (4), and the notch (5) on the beam (8) is similar to that of the girder (1).

FIG. 5 is a perspective view showing a state in which a joist (9) is partially attached to the girder (1) and the beam (8) assembled in the cross girder and the floor board (10) is stretched. The floor board (10) is made of expanded metal or iron net.

The handrail (2) may be a handrail that can be expanded and contracted in stages as shown in FIG. For example, a handrail is made into a double pipe and small holes (11) corresponding to the respective pipes are bored, and a bar (12) which can pass through the small holes (11) responding to both is attached. Further, a hook member (14) having a handle (13) is installed on the side surface of the girder (1). The hook member (14) is set on the housing (16) while receiving the spring force of the spring (15). A hook receiver (17) with which the hook member (14) can be fitted is installed on the side surface near the main opening of the handrail (2).

FIG. 7 shows an embodiment in which a work floor unit in which a handrail is arranged on a horizontal member according to the present invention is transplanted to a foldable temporary work floor system. In this case, two work floor units are connected by a hinge (18). Folding legs that can support these work floor units use conventional systems.

When the handrail (2) that is designed to be slidable into and out of the girder (1) (see FIG. 2) is pulled out horizontally, the cotter (7) protruding from the main opening of the handrail (2) Slides on the inner top surface of the lip (4). When the cotter (7) hits against the lid (3) installed at the end of the girder (1), the handrail frame is no longer pulled out. After reaching that state, raise the handrail frame this time. When standing up, make sure that the cotter (7) is the center of rotation of the hinge. Figure 3 shows the handrail frame completely raised. When the handrail frame is completely raised, the body of the handrail (2) fits into the notch (5) formed at the end of the girder (1). This allows the outer surface of the handrail (2) and the end surface of the girder (1) to be flush. After the fitting is completed, the handrail (2) can no longer rotate, but it can still rotate in the returning direction, and cannot function as a handrail frame as it is. Therefore, the hook member shown in FIG. (14) is engaged with the hook receiver (17). Due to the engagement, the handrail frame cannot rotate in both directions, and can serve as a handrail frame. As shown in FIG. 6, when the handrail (2) is capable of expanding and contracting in stages, the height of the handrail can be adjusted by expanding and contracting the handrail (2).

The floor plate (10) is abutted on and fixed to the upper surface of the girder (1) and the upper surface of the joist (9) by contacting them. Therefore, the structure of the floor set consisting of the structural material and the floor board remains the same. The handrail frame is included in the girder (1) or the beam (8) which is a structural material. Therefore, the handrail frame can be taken in and out from here, and the work floor and the handrail frame can be integrated with each other, and the work floor equipped with the handrail frame can be compactly assembled to save space. Light-weight shaped steel such as lip channel steel has a larger cross-section coefficient than ordinary shaped steel with the same cross-sectional area, and because of its high cross-sectional efficiency in terms of cross-sectional area, it is widely used as a structural material.

[0013]

[Effect of device]

 According to the present invention, since the handrail frame is assembled in the inner space of the light-weight shaped steel that can be used as the structural material, the handrail frame can be smartly assembled to the work floor. Since the handrail frame fits on the back of the work floor, the work floor surface is cleaner than when the handrail frame is folded toward the top of the work floor. Even if the handrail frame that interferes with the work is stored, the handrail frame does not occupy the surface of the work floor and you can work safely at your feet. The work floor unit according to the present invention has a flat base plate shape including the handrail frame, which facilitates stacking at the collection site and improves the degree of integration. As a floor unit, for example, it can be incorporated as a work floor of a folding temporary work floor, or can be easily used as a work floor of a drive lifting work floor.
