Description

  The present invention relates to a mounting structure for a beam frame used in a temporary scaffold assembled at a construction site or the like, in particular, a wedge-tight scaffold.

  Conventionally, a temporary scaffold is provided along a building such as a building at a construction site, and is used by a site worker for repairing or painting a building. In recent years, so-called wedge-tightened scaffolds in which wedges are used to connect a plurality of types of temporary members used in temporary scaffolds have been employed (see, for example, “Patent Document 1”).

  As shown in FIG. 13, the wedge-tightened scaffold is usually constructed by erecting a support column 41 for each basic span (for example, 1829 mm) and connecting each temporary member to the support column 41. When the wedge-binding scaffold is provided along a building having a condominium or a store, an opening S having a predetermined space may be formed depending on the entrance of the condominium or the store (see FIG. 13). Through this opening S, people can go in and out of an apartment, a store, etc., or carry things.

  When the opening S is formed in the wedge-tightening type scaffold, a temporary member is also provided in an upper part of the opening S, so that a beam frame 42 for supporting them is usually attached. The beam frame 42 is attached to the upper part of the opening S so as to extend in the lateral direction on both the front step side (side close to the building) and the rear step side (side far from the building) (in FIG. 13, the rear step step). Only the side beam frame 42 is shown.).

  The beam frame 42 has substantially the same length as the width of the opening S. As shown in FIG. 14, two horizontal members 43 and 44 are arranged in parallel, and they are connected by a vertical member 45, a diagonal member 46, and the like. Has been formed. A tenon 47 is formed on the upper portion of the vertical member 45 so as to be continuous with the vertical member 45. In the tenon 47, a support column 41 disposed in an upper portion of the opening S is fitted and erected.

  As shown in FIG. 15, the end portion of the beam frame 42 is connected to a flange 48 provided on the support column 41. More specifically, the connecting member 49 of the beam frame 42 is sandwiched between the flanges 48, and the wedge 50 is passed through the connecting member 49 and is fastened to the latching hole 51 formed in the flange 48, whereby the beam frame 42. Are connected to the support column 41.

  In a wedge-tight scaffold, the installation interval W (see FIG. 13) between the support columns 41 adjacent to each other in the left-right direction is usually a basic span, and the support column 41 is erected for each basic span. Therefore, the width of the opening S is set so that the basic span is a reference, that is, a width that is a multiple of the basic span.

  Similarly, since it is necessary to maintain the basic span of the support column 41 also in the upper portion of the opening S, the beam frame 42 is provided with the vertical members 45 and tenons 47 at the interval W that matches the installation interval of the support columns 41. (See FIG. 14).

  Here, in a construction site, there is a case where it is desired to set the width of the opening S to an arbitrary width. For example, when the building is a store, the width of the opening S is matched with the width of the entrance of the store, or when the vehicle passes through the opening S, the width of the opening S is slightly larger than the width of the vehicle. It may fit the large width.

  However, as described above, the width of the opening S in the wedge-tight scaffold is substantially the same as the length of the beam frame 42 and is set to a width that is a multiple of the basic span of the column 41. If the width of S is set to an arbitrary width, the conventional beam frame 42 cannot be used.

  Therefore, the field worker must prepare a beam frame having a width other than a multiple of the basic span, and the width of the opening S is often different for each construction site. There was annoyance that it was necessary to prepare a beam frame corresponding to S for each construction site. In addition, when the number of types of beam frames increases, there is a problem that the management thereof becomes complicated.

In a normal wedge-tightened scaffold, the scaffold plate 2 is supported by the arm wood 4 and the handrail frame 3 (not shown) is connected to the other retaining hole 6 of the flange 5.

  Returning to FIG. 1, in the wedge-binding scaffold, an opening S having a predetermined space may be formed depending on the entrance of a condominium, a store, or the like. A pair of beam frames 11 for supporting a temporary member disposed in the upper portion of the opening S is attached. The pair of beam frames 11 are attached to the upper part of the opening S so as to extend in the horizontal direction on both the front step side (side closer to the building) and the rear step side (side far from the building). In FIG. 1, only the beam frame 11 on the rear foot side is shown.

  Here, the opening S is usually set so that the width thereof is substantially the same as a multiple of the basic span (for example, 1829 mm) between the struts 1, but any arbitrary number other than a multiple of the basic span is necessary. Sometimes set to width. The mounting structure of the beam frame 11 of this embodiment is easy to the set width of the opening S even when the width of the opening S may be set to an arbitrary width other than a multiple of the basic span. It can correspond to.

The beam frame receiving member 21 includes a pair of U-shaped members 22 that are arranged in parallel in the left-right direction and support the beam frame 11. In order to support the beam frame 11, the pair of U-shaped members 22 are formed so that the curved surface portion is positioned below. The pair of U-shaped members 22 are provided with a flat upper connection member 23 and a lower connection member 24 for connecting them to the upper and lower portions of one side surface thereof.

  On the back side of the upper connecting member 23, an insertion piece 25 extending in the vertical direction is provided. The insertion piece 25 is inserted into the retaining hole 6 of the flange 5 positioned at the upper corner C (see FIG. 1) of the opening S when the beam frame receiving member 21 is attached. More specifically, the insertion piece 15 is inserted into the retaining hole 6 (see FIG. 2) on the opposite side of the retaining hole 6 to which the arm wood 4 is attached in the flange 5. On the other hand, a clamp 27 is bolted to the back side of the lower connecting member 24 via a flat mounting member 26, for example. The clamp 27 is for fixing the beam frame receiving member 21 to the column 1, and tightens the column 1 with a predetermined tightening torque when the beam frame receiving member 21 is attached.

  Each of the U-shaped members 22 is formed with a through hole 28 at the same height position on the opposing surface. A U-shaped bolt 29 is attached to the pair of U-shaped members 22 so as to pass through the through holes 28 and span the pair of U-shaped members 22. A wing nut 30 is screwed to the end of the U-shaped bolt 29. The wing nut 30 is used to fasten and fix the upper horizontal member 12 and the auxiliary horizontal member 17 of the beam frame 11 to the pair of U-shaped members 22.

  One or a plurality of beam frame passing members 31 are spanned between a pair of beam frames 11 attached to each of the front stepping side and the rear stepping side (in the depth direction in FIG. 1). The beam frame passing member 31 is arranged at a predetermined position of the upper horizontal member 12 of the beam frame 11 as will be described later. In FIG. 1, three beam frame passing members 31 are arranged.

  As shown in FIG. 8, the beam frame passing member 31 includes a long arm wood 4 and a column receiving member 32 connected to both ends thereof. The arm wood 4 includes a pipe-shaped main body 4a, a connecting member 8 and a wedge 7 provided at both ends of the main body 4a. The arm lumber 4 of the beam frame passing member 31 in the present embodiment is not newly designed and manufactured for the beam frame passing member 31, but is generally used in a wedge-tight scaffold as shown in FIG. The arm lumber 4 used for is used.

  FIG. 9 is a perspective view of the column support member 32, FIG. 10 shows the external shape of the column support member 32, (a) is a front view, (b) is a top view, and (c) is a right side view.

  The column receiving member 32 includes a cylindrical cylindrical portion 33, and a tenon 34 having a diameter slightly smaller than the diameter and a predetermined length is provided on the upper portion of the cylindrical portion 33. The tenon 34 is for erecting the support 1 by inserting the support 1. On the peripheral surface of the cylindrical portion 33, a flange 36 having three retaining holes 35 formed so as to spread in the horizontal direction is provided. In addition, a hook portion 38 having a U-shape in side view for hooking on the beam frame 11 is provided on a part of the peripheral surface of the cylindrical portion 33 via a connection portion 37 having a substantially U-shape in plan view. Yes. The hook portion 38 is formed so that the curved surface portion is positioned upward so as to be hooked to the beam frame 11.

  By connecting the connecting member 8 and the wedge 7 of the arm lumber 4 to the latching hole 35 formed on the opposite side of the hook portion 38 in the flange 36 of the prop receiving member 32, the prop receiving member 32 and the arm lumber are connected. 4 is integrated. Further, the other strut receiving member 32 is connected to and integrated with the connecting member 8 and the wedge 7 at the other end of the arm wood 4.

  Next, a procedure for attaching the beam frame 11 to the wedge-tight scaffold will be described.

  When the opening S is formed in the wedge-tightening type scaffold, in order to support the scaffold member disposed in the upper part of the opening S, the temporary member (the support column 1) is temporarily formed in the region where the opening S is formed. Temporary scaffolding by handrail material 3 and arm wood 4 etc. is temporarily assembled.

  Next, the beam frame receiving member 21 is attached above the temporarily assembled temporary scaffold. More specifically, the beam frame receiving member 21 is attached to each of the flanges 5 positioned at both upper corners C (see FIG. 1) of the opening S. That is, the insertion piece 25 of the beam frame receiving member 21 is inserted into the retaining hole 6 of the flange 5, and the column 1 having the flange 5 is tightened with a predetermined tightening torque by the clamp 27. As a result, the beam frame receiving member 21 is fixed to the support column 1 at the upper corner C of the opening S. Note that a total of four beam frame receiving members 21 are attached to the upper corners C on the front stepping side and the rear stepping side.

  Next, as shown in FIG. 11, the beam frame 11 is supported by the beam frame receiving member 21 fixed to the column 1. More specifically, the upper horizontal member 12 and the auxiliary horizontal member 17 of the mounting portion 16 of the beam frame 11 are arranged inside the pair of U-shaped members 22, and the U-shaped bolts 29 are connected to the pair of U-shaped members 22. The mounting portion 16 of the beam frame 11 is fixed to the beam frame receiving member 21 by being inserted into the through hole 28 and tightened with the wing nut 30.

  As shown in FIG. 12, the beam frame passing member 31 is disposed at a predetermined position (a position where the column 1 is erected) of the upper horizontal member 12 of the beam frame 11. In other words, the hook portions 38 of the both column receiving members 32 are hooked so that the beam frame passing member 31 is hung on the upper horizontal member 12 of each beam frame 11 on the front stepping side and the rear stepping side.

  Next, the struts 1 are inserted into the tenons 34 of the respective strut receiving members 32. And although not shown in FIG. 12, the scaffolding board 2 is arrange | positioned between the handrail materials 4 of the adjacent beam frame passing member 31 so that they may be spanned. Moreover, the handrail 3 is attached between the support | pillars 1 adjacent to the left-right direction. Thereafter, the temporary scaffold temporarily assembled in the region of the opening S is disassembled. Thereby, the space of the opening S is formed.

  Thus, the beam frame 11 can be easily attached to the upper part of the opening S by the beam frame receiving member 21. Since the beam frame passing member 31 can be hung to a predetermined position of the upper horizontal member 12 of the beam frame 11, the column 1 installed in the upper portion of the opening S can be erected at a suitable position. Since the width of the opening S can be set at the position where the support column 1 is arranged, the width of the opening S can be set to a width other than a multiple of the basic span, that is, the width of the opening S can be set to an arbitrary width. Can be set.

  Moreover, according to this embodiment, the beam frame 11 should just be larger than the width | variety of the opening S at least, and since it is supported by the beam frame receiving member 21, when the width of the opening S differs for every construction site However, it is not necessary to prepare beam frames with different lengths for each construction site. Also, there is no need to manage them. Further, since the beam frame 21 only needs to have a length larger than the width of the opening S, it does not require dimensional accuracy unlike the conventional beam frame 42. Therefore, the beam frame 11 can be easily manufactured.

  Further, the beam frame 11 is attached at a position deviated from a line connecting the axes of the respective struts 1 of the wedge-binding scaffold in plan view. Specifically, the beam frame 11 on the front step side is arranged closer to the building from the line connecting the axes of the columns 1 by the beam frame receiving member 21, and the beam frame 11 on the rear step side is arranged on each column 1. It is arranged at a position farther away from the building than the line connecting the axes. The conventional beam frame 42 is arranged on the same line as the line connecting the axes of the columns 1 and the length of the beam frame 42 and the width of the opening S are substantially the same. It was difficult to work. However, in this embodiment, since the beam frame 11 is attached at a position deviated from the line connecting the axes of the respective columns 1, workability at the time of attachment can be improved.

  Moreover, as the support | pillar receiving member 32 of this embodiment uses the versatile arm wood 4 as mentioned above, it can reduce manufacturing cost. Further, since the versatile arm wood 4 is used, for example, even if the width in the depth direction of the wedge-tightened scaffold is suddenly changed at the construction site, only the arm wood 4 needs to be replaced, so that it can be flexibly handled. be able to.

  The scope of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. For example, the shape, size, quantity, and the like of the beam frame 11, the beam frame receiving member 21, the beam frame passing member 31, and the column receiving member 32 in the above embodiment are not limited to the above embodiment, and can be appropriately changed in design. It is. For example, in the above-described embodiment, the flange 5 is provided on the support column 1. However, instead of the flange 5, for example, a U-shaped pocket body in a top view is provided, and each temporary member is connected to the pocket body. Good.
