It is fixed by. The scaffold plate holder 36 has wall portions 36b as locking projections on both sides in the short (width) direction of the beam frame 3, and is formed in a substantially U-shaped cross section, with the open side facing upward. In this way, it is fixed to the end beam frame 4 and the central beam frame 5. The scaffold plate holder 36 is formed along the bottom surfaces 61a and 61b of the main body 61, which will be described later, constituting the scaffold plate 6 so that the scaffold plate 6 can be suitably supported from below. Specifically, the scaffold plate holder 36 is formed so that the degree of opening of the wall portion 36b increases as it extends along the side portion 61b extending obliquely with respect to the bottom portion 61a of the main body 61. ing.

  As shown in FIG. 2, the scaffold plate 6 is attached to the beam frame 3 from above and is arranged so as to be continuous in the longitudinal direction of the beam frame 3. Specifically, in the present embodiment, the two end-side scaffold plates 6a constituting the scaffold plate 6 and the central scaffold plate 6b provided therebetween are supported by the scaffold plate holder 36 from below. Attached to the two end beam frames 4 and the central beam frame 5 constituting the beam frame 3 from above.

<About connecting structure of scaffolding plates>
Next, with reference to FIG. 3, the connection structure of the adjacent end side scaffold board 6a and the center scaffold board 6b is demonstrated. 3A is a perspective view showing an end portion of the scaffolding plate 6 (end-side scaffolding plate 6a), and FIG. 3B is an illustration of adjacent scaffolding plates 6 (end-side scaffolding plate 6a and central scaffolding plate). It is a perspective view which shows the state which connected 6b).

  In the end side scaffolding plate 6a and the central scaffolding plate 6b, plates 63 projecting outward in the longitudinal direction from other parts are attached to respective ends facing each other in the longitudinal direction (also referred to as extending direction). It has been. The plate 63 corresponds to a protruding portion and a connecting portion according to the present invention, and is sandwiched between a receiving portion 64 and a lid 62 described later in a direction along the lid 62 as an upper plate of the scaffold plate 6. These are attached in a substantially horizontal direction by a rivet R4 described later. In particular, the plate 63 is attached so as to be biased to one side of the center of the lid 62 in the short direction.

Thus, between the receiving part 64 and the lid 62, the plate 63 is attached so as to be biased to one side with respect to the center of the lid 62 in the short direction, so that the lid 62 in the short direction A gap will be formed on the other side of the center.
As shown in FIG. 3 (b), this gap formed on the end-side scaffold plate 6a side is a fitting portion where a plate 63 attached to the central scaffold plate 6b adjacent to the end-side scaffold plate 6a is fitted. Yes, it functions as a fitting gap CL that is a connecting portion that connects the end-side scaffold plate 6a and the central scaffold plate 6b.
Similarly, in the center scaffold plate 6b, the plate 63 attached to the lid body 62 of the end side scaffold plate 6a is fitted into the fitting gap CL formed on one side of the center in the short side direction of the lid body 62. It will be.
Thus, the end-side scaffolding plate 6a and the central scaffolding plate 6b are connected by the pair of plates 63 and the fitting gap CL. Then, the one side plate 63 of the end side scaffold plate 6a and the central scaffold plate 6b and the upper surface of the other receiving portion 64 and the lower surface of the lid 62 are in surface contact with each other, whereby the end side scaffold plate 6a and the central scaffold plate 6b. The relative wobbling in the vertical direction is suppressed.

<About the components of the scaffolding plate>
Next, with reference to FIGS. 4-9, each component of the center scaffold board 6b among the scaffold boards 6 is demonstrated in detail. In addition, about the end side scaffold board 6a, the point which is not attached to the plate 63 and the receiving part 64 which are mentioned later on the side connected to the central scaffold board 6b, and the other side is the center scaffold board 6b. It is mainly different. Therefore, in order to avoid redundant description, description of the configuration of the end-side scaffold plate 6a is omitted.

  4A is a front view showing the main body 61 constituting the scaffold plate 6 (central scaffold plate 6b), FIG. 4B is a plan view of the main body 61, and FIG. 4C is the main body. FIG. FIG. 5A is a front view showing the lid 62 constituting the scaffold plate 6 (central scaffold plate 6b), FIG. 5B is a plan view of the lid 62, and FIG. 4 is a side view of a lid body 62. FIG. Further, FIG. 6A is a front view showing the receiving portion 64 constituting the scaffold plate 6 (central scaffold plate 6b), and FIG. 6B is a plan view of the receiving portion 64. FIG. 7 is a plan view showing the plate 63 constituting the scaffold plate 6, and FIG. 8 is a side view showing the attachment reinforcing plate 65. 9 (a) is a front view showing the scaffold plate 6 (central scaffold plate 6b), FIG. 9 (b) is a plan view of the scaffold plate 6, and FIG. 9 (c) is a side view of the scaffold plate 6. It is.

  As shown in FIG. 9, the central scaffolding plate 6 b has a lid mainly composed of a main body 61 having a substantially inverted Ω cross section and a U-shaped lid body 62 covering the main body 61 from above. It has a box shape. As will be described later, the main body 61 and the lid 62 are fixed by a rivet R1 which is a so-called blind rivet.

  As shown in FIG. 4, the main body 61 includes a long plate-like bottom portion 61a, a pair of side portions 61b extending obliquely upward from both short-side ends of the bottom portion 61a, and a bottom portion 61a from the upper ends of the pair of side portions 61b. The edge portion 61c extends outward in the lateral direction in parallel with the edge portion 61, and the hanging portion 61d extends so as to hang vertically from the lateral direction outer end portion of the edge portion 61c.

In particular, the inclination angle of the pair of side portions 61b extending obliquely from both sides in the short side direction of the bottom portion 61a is about 110 °. The inclination angle and interval of the pair of side portions 61b substantially coincide with the inclination angle and interval of the pair of wall portions 36b of the scaffold plate holder 36 with respect to the portion extending substantially horizontally. As described above, the side portion 61b of the main body 61 is formed along the scaffold plate holder 36, thereby restricting the main body 61 and consequently the scaffold plate 6 from moving in the lateral direction of the beam frame 3. , Can suppress wobble.
Further, two through holes 61e drilled in the plate thickness direction are formed at predetermined intervals in the longitudinal direction on both ends in the longitudinal direction of the main body 61 in the hanging portions 61d on both sides in the short direction. The through hole 61e is a hole through which a rivet R1 (described later) for fixing the main body 61 and the lid body 62 is passed.

As shown in FIG. 5, the lid 62 has a U-shaped cross-section with the open side facing downward, and a top plate portion 62a serving as a scaffold for the operator, and a short direction of the top plate portion 62a And extending portions 62b extending downward (from the side of the beam frame 3) from both ends, and are formed of a plate material such as aluminum.
In addition, two through holes 62e drilled in the plate thickness direction are formed at predetermined intervals in the longitudinal direction on both ends in the longitudinal direction of the lid body 62 in the extending portions 62b on both sides in the lateral direction. . The through hole 62e is a hole through which a rivet R1 (described later) for fixing the main body 61 and the lid body 62 is passed.

The extension 62b of the lid 62 has a function of restricting movement of the lid 62 and the scaffold plate 6 in the short direction by engaging with the wall portion 36b of the scaffold plate holder 36 together with the main body 61. . As shown in FIGS. 5B and 5C, the extending portion 62b is formed shorter in the longitudinal direction than the top plate portion 62a. Specifically, the extension portion 62b is formed with a notch 62c so as to be shortened by the length of the portion to which the receiving portion 64 is attached from both longitudinal ends of the top plate portion 62a.
In addition, since the main body 61 and the lid body 62 of the scaffold plate 6 are made of a plate material, they can be easily formed by press working, and the weight is reduced by forming a hollow between the two.

  As shown in FIG. 9, plates 63 described later are fixed to both side ends in the longitudinal direction of the lid 62 by rivets R <b> 4 which are so-called blind rivets at positions sandwiched between receiving portions 64 and the lid 62 described later. Has been. Specifically, four through holes 62d penetrating in the thickness direction are formed on one side of one end side in the longitudinal direction of the lid body 62 from the center in the lateral direction. With respect to the four through holes 62d, other four through holes 62d are formed at positions that are rotationally symmetric (two-fold symmetric) with the center of the lid 62 as a central axis in plan view. A plate 63 described later is fixed to the lid 62 by passing the rivet R4 through the through holes 62d. The plate 63 and the receiving portion 64 are also provided in two so as to be rotationally symmetric (two-fold symmetric) with the center of the lid 62 in the plan view as the central axis.

The receiving portion 64 is a member that supports a plate 63, which will be described later, from the lower side, and is formed in a U-shaped cross section as shown in FIG. At both ends, side portions 64d are formed extending upward.
The receiving portion 64 includes a protruding portion-side bottom portion 64b on one side in the short direction of the lid body 62 on the side to which the plate 63 is attached, and a fitting hole-side bottom portion 64a facing the fitting gap CL. .

A through hole 64 c penetrating in the vertical direction is formed in the protruding portion side bottom portion 64 b at intervals in the direction along the short direction of the lid body 62. The through hole 64c is a hole through which the two rivets R4 for fixing the lid body 62, the plate 63, and the receiving portion 64 are passed.
And the protrusion part side bottom part 64b is formed longer in the direction along the longitudinal direction of the cover body 62 than the fitting hole side bottom part 64a. The protruding portion side bottom portion 64b of the receiving portion 64 is formed in this manner, so that the contact area with the plate 63 is increased while compensating for the reduction in rigidity due to the provision of the through hole 64c. It is possible to support the plate 63 suitably while suppressing the above.

  The side portion 64 d is formed at a height of about １ ／ of the height of the lid body 62, and the upper end portion thereof is welded to both sides in the short direction of the lid body 62 and joined to the lid body 62. ing. Further, the side portions 64 d at both ends in the short side direction of the lid body 62 in the receiving portion 64 are welded to both sides in the short side direction of the lid body 62 at positions where the upper ends thereof coincide with the upper surface of the lid body 62. The receiving portion 64 is attached to the lid body 62 at the end portions of the adjacent scaffold plates 6 in the longitudinal direction facing each other.

  As shown in FIG. 7, the plate 63 has a shape in which two rectangles are obliquely overlapped in plan view. In other words, a square notch 63a with one corner in the plate 63 is cut out, and the diagonal corner is also cut out by a rectangular notch 63b. The plate 63 shown in FIG. 3 does not show the notch 63b, the chamfer 63c, or the like, but the plate 63 shown in FIG. 3 is simplified for explanation, and the specific shape is shown in FIG. It is shown in

Thus, by forming the notch 63a in the plate 63, the plate 63 can be positioned in the longitudinal direction of the lid 62 by bringing the edge of the notch 63a into contact with the receiving part 64.
Furthermore, by forming the notch 63 b in the plate 63, the portion of the plate 63 that protrudes from the lid 62 can be disposed closer to the end than the center in the short direction of the lid 62. For this reason, when connecting the plate 63 which protrudes from the adjacent end side scaffold board 6a, it can suppress that a mutual plate 63 interferes. Furthermore, in a portion where the through-hole 63d is formed and is disposed below the lid body 62, a large area can be secured and can be stably attached by a rivet R4 described later.

At one of the other corners of the plate 63, a chamfer 63c that is cut obliquely is formed. Thus, the chamfer 63c is formed, so that the plate 63 can be easily inserted into the fitting gap CL.
Further, the plate 63 is formed with four through holes 63d through which the rivet R4 is passed, and the rivet R4 is passed through the two through holes 63d that are positioned on the end of the lid 62 in the longitudinal direction. Accordingly, the lid body 62 and the receiving portion 64 are fixed integrally.

  An attachment reinforcing plate 65 shown in FIG. 8 is attached to the inner surface side of the extending portion 62b extending downward from both sides of the lid 62 in the short direction. The attachment reinforcing plate 65 is provided for reinforcement of attachment by the rivet R1 passing through the through hole 61e of the main body 61 and the through hole 62e of the lid body 62 as described above. The attachment reinforcing plate 65 is made of a rod-shaped plate material, and two through holes 65a for passing the rivets R1 are formed on both ends thereof. The two through holes 65a are formed at substantially the same interval as the through hole 61e of the main body 61 and the through hole 62e of the lid 62.

  As described above, the lid 63 constituting the central scaffold 6b of the scaffold 6 has a plate 63 and a rotational symmetry (two-fold symmetry) about the center of the lid 62 in plan view. Since the receiving part 64 is attached, there is no directionality. For this reason, when attaching the adjacent scaffold boards 6 mutually, it becomes possible to attach without minding the direction of the center scaffold board 6b, and can improve work efficiency.

In addition, as described above, the upper end of the side portion 64 d of the receiving portion 64 is welded to the lid body 62 so as to coincide with the upper surface of the lid body 62, and the side portion 64 d is about 1 in height of the lid body 62. / 3 height. For this reason, as shown in FIG. 3B, a space SP is formed below the plate 63, strictly below the receiving portion 64.
As described above, the notch 62 c is formed in the extending part 62 b of the lid 62, so that the space SP below the receiving part 64 is opened to the outside in the short direction of the lid 62. Yes.
As described above, since the space SP is opened by the notch 62c, the operator can easily access the beam frame 3 even when the scaffold plate 6 is attached to the beam frame 3. For this reason, it is possible to easily perform attachment work of handrails and other members (not shown) to the beam frame 3 without removing the scaffold plate 6.

<About clamp members>
Next, with reference to FIGS. 10 to 12, the clamp members 10 and 11 as the separation suppressing members that suppress the wobbling of the scaffold plate 6 will be described. 10 is a perspective view showing the end-side scaffold plate 6a fixed by the clamp members 10 and 11 attached to the support column 2. FIG. 11 is a perspective view showing the clamp member 10. FIG. 3 is a perspective view showing a member 11. FIG.

  The clamp members 10 and 11 have a function of directly suppressing the wobbling of the end-side scaffold plate 6a, in other words, a function of suppressing the end-side scaffold plate 6a from being separated from the beam frame 3. The said function is implement | achieved when the clamp members 10 and 11 are attached to the support | pillar 2 by the clamp parts 10a and 11a (clamped), and the horizontal wall 10d or the horizontal board 11b contact | abuts from the upper side to the end side scaffold board 6a. Is done. Thus, the wobbling of the end scaffolding plate 6a can be suppressed, so that the wobbling of the central scaffolding plate 6b fitted to the end side scaffolding plate 6a can be indirectly suppressed. Can be suppressed.

  The clamp member 10 has a substantially vertical direction in a state in which the clamp portion 10a, a locking holder 10b capable of attaching another member attached to the side portion of the clamp portion 10a, and the clamp portion 10a attached to the column 2 A vertical wall 10c as a vertical portion extending in the horizontal direction, and a horizontal wall 10d in contact with the upper surface of the end-side scaffolding plate 6a extending in a substantially horizontal direction.

  The clamp part 10a is a part for fixing to the support | pillar 2 by utilizing the fastening force by a screw. The locking holder 10b provided on the side portion of the clamp portion 10a is formed in a U-shaped cross section and extends vertically. Further, a vertical wall 10c extending substantially vertically is fixed so as to close the open side of the U-shaped section of the locking holder 10b. As described above, the clamp member 10 includes the locking holder 10b, so that a handrail or a connecting member for expanding a scaffold in a substantially horizontal direction can be provided in a space surrounded by the locking holder 10b and the vertical wall 10c. Since it becomes possible to insert and fit, expandability can be improved.

  The vertical wall 10c and the horizontal wall 10d are integrally formed with an L-shaped angle. In other words, the horizontal wall 10d is formed to bend and extend vertically from the lower end of the vertical wall 10c to the vertical wall 10c. The horizontal wall 10d is a pressing portion that comes into surface contact with the upper surface of the end-side scaffold plate 6a and suppresses the swinging of the end-side scaffold plate 6a, and the inner surface of the clamp portion 10a that extends along the column 2 extends.
