Description

  The present invention relates to bracing for temporary scaffolds.

  Temporary scaffolding will be installed on the outer periphery of the building during construction work. In this case, first, a plurality of support columns are arranged at predetermined intervals. A scaffolding plate is installed between the columns to form a one-level scaffold. And the support | pillar is sequentially added upwards, and a scaffold board is constructed similarly, and the scaffold of several levels is formed. In the construction work of such a temporary scaffold, as a safety measure for the work of adding the scaffold upward, the scaffolding material such as diagonal, horizontal, or vertical is used as a handrail before the scaffold plate is constructed. Arranged.

  When the scaffolding is arranged, the brace for temporary scaffolding is detachably attached to the wedge support (holder) of the scaffolding column. In the case of a general scaffold column, as shown in FIG. 12, it is arranged at four locations 90 ° around the column (see, for example, the drawings of Patent Document 1). Specifically, the lower wedge receiver 2 is composed of 2a, 2b, 2c and 2d, and the upper wedge receiver 3 is composed of 3a, 3b, 3c and 3d. The upper and lower wedge receivers have the same shape. When diagonal members, horizontal members, etc. are attached to the wedge receivers disclosed in FIG. 12, the diagonal members, horizontal members, etc. are attached to the opposite wedge receivers (for example, between 3a and 3c) between the two scaffold columns. (See Patent Document 1). Alternatively, the diagonal member, the horizontal member, and the like are engaged between the wedge receivers on the left and right of the wedge receivers at the opposite positions (for example, between 2b and 2b) (see, for example, Patent Documents 2, 3, 4, etc.).

  In diagonal members, horizontal members, etc. installed between the scaffolding struts, improvements have been made for securing the scaffold strut wedges firmly and easily (see Patent Documents 2, 3, 4 etc.). ). However, in reality, the correspondence between the diagonal members, the horizontal members, and the like and the wedge receivers that accept them are fixed. For this reason, there is a demand to flexibly select a wedge receiver used for anchoring diagonal materials, horizontal materials, etc. in consideration of the structure of the building where the temporary scaffolding is constructed, workability at the site, and the like. Moreover, since materials such as diagonal materials and horizontal materials are procured according to the position of the wedge receiver to be used at present, it is complicated.

  Therefore, it is possible to select the mounting position of the wedge support of the scaffolding strut on the side of the diagonal material or horizontal material provided for the temporary scaffolding for the temporary scaffolding, and the configuration of the bracing that can flexibly respond to the structure of the building and field work is desired. It came to.

  As shown in FIG. 1, the brace 10 for temporary scaffolding of the embodiment includes two diagonal members 12 and 12 and a horizontal member 11 that are laid between the scaffolding struts 1 and 1. The diagonal members 12 and 12 are arranged in an X shape so as to intersect between the scaffolding columns 1 and 1. The lower connecting portions 20 are respectively provided at the lower end portions 16 of both diagonal members 12. The lower connecting portion 20 is detachably attached to the lower wedge receiver 2 provided on the scaffolding column 1. In addition, a horizontal member 11 is pivotally attached to the upper ends 14 of both diagonal members 12, 12 and is attached to both ends of the horizontal member 11 so as to be removable with respect to the upper wedge receiver 3 provided on the scaffolding column 1. The upper connection part 40 is provided.

  The arrangement and structure of the lower wedge receiver 2 (2a, 2b, 2c, 2d) and the upper wedge receiver 3 (3a, 3b, 3c, 3d) in the scaffold column 1 are the same as the scaffold column 1 of FIG. 12 disclosed in the background art. This is the same as the structure of the wedge receiver in FIG. The upper wedge receiver and the lower wedge receiver have the same shape. In the present specification, for convenience of explanation, the wedge holders of the scaffolding columns are distinguished from each other.

  The structure of the upper connection part 40 of an Example is demonstrated using FIG.2 and FIG.3. As can be understood from FIG. 2 from the main top view in the vicinity of the upper connecting portion 40, the upper connecting portion 40 is arranged in the order of the diagonal member 12, the horizontal member 11, the upper wedge member 50, and the auxiliary plate member 60 from the lower side of the drawing. The And the axial support pin 45 has penetrated said 4 types of members, and each member is slidably overlapped. Further, the fixing pin 41 is inserted through the upper wedge member 50 and the auxiliary plate member 60.

  FIG. 3 is a main exploded perspective view of the upper connecting portion 40. A shaft support hole 17 is formed in the diagonal member 12, a shaft support groove hole 43 that is a long hole in the longitudinal direction is formed in the horizontal member 11, a shaft support hole 55 is formed in the upper wedge member 50, and the auxiliary plate member 60. In the longitudinal direction, a shaft support groove hole 65 which is a long hole is formed. Therefore, the shaft support pin 45 passes through the shaft support hole 17, the shaft support groove hole 43, the shaft support hole 55, and the shaft support groove hole 65. As can be understood from the shape of each hole shown in the drawing, the diagonal member 12 and the upper wedge member 50 are only rotated. On the other hand, the horizontal member 11 and the auxiliary plate member 60 can be moved laterally (moving in the longitudinal direction of the horizontal member) in addition to rotation.

  In the upper connecting portion 40 provided in the horizontal member 11, the upper wedge member 50 is formed with a groove portion 51 that is engaged with the upper wedge receiver 3 and becomes a long hole in the horizontal direction. The fixing pin 41 is inserted into the groove 51 and the fixing pin hole 61 of the auxiliary plate member 60. Similarly, as can be understood from the shapes of both holes shown in the drawing, the auxiliary plate member 60 can move in the horizontal direction by the length of the long hole shape with respect to the upper wedge member 50.

  The upper wedge member 50 is attached so as to be movable in a horizontal first position and a second position (both described later) with respect to the fixing pin 41 of the end portion 42 of the horizontal member 11. The upper wedge member 50 is provided with an upper short leg portion 52 and an upper long leg portion 53, and an upper leg portion 54 is formed between the both leg portions 52, 53. Therefore, when the upper short leg portion 52 and the upper long leg portion 53 are inserted into the upper wedge receiver 3, the upper wedge receiver 3 is sandwiched by the upper leg portion 54, and the upper wedge receiver 3 and the upper connecting portion 40 are engaged. Is done. A flange 56 is formed at the tip of the upper long leg 53. The eaves part 56 is for improving the fixing property (hook condition) between the upper wedge receiver 3 and the upper wedge member 50 (see FIGS. 4 and 5).

  The upper end 14 of the diagonal member 12 is formed as an arcuate edge 15. Therefore, when the upper wedge member 50 moves laterally (moves in the longitudinal direction of the horizontal member) between the first position and the second position (both described later) along the groove 51, the diagonal member 12 moves to the fixing pin 41. On the other hand, it becomes a structure which can contact | abut, rotating the position of the circular-arc-shaped edge 15. This is because when the angle between the diagonal member 12 and the horizontal member 11 is changed, the arc-shaped end edge 15 of the diagonal member 12 almost always abuts against the fixing pin 41, so that the angle between the diagonal member 12 and the horizontal member 11 is increased. Deformation can be stabilized.

  In the upper connection part 40 of the embodiment, an auxiliary plate member 60 is also provided. The auxiliary plate member 60 has a restriction piece 62. The diagonal member 12 is pivotally attached to the upper wedge member 50 and the horizontal member 11 by a pivot pin 45 so as to be rotatable. For this reason, if there is no restriction piece 62, the diagonal member 12 easily turns carelessly. Then, the handling at the time of engaging the upper connection part 40 to the upper wedge receiver 3 (3a, 3b, 3c, 3d) tends to become complicated. Therefore, the restriction piece 62 is provided together with the auxiliary plate member 60. As can be understood from FIG. 2 described above, the restriction piece 62 has a positional relationship covering the upper portion of the diagonal member 12. Since the diagonal member 12 receives the resistance of the restricting piece 62, the rotation of the diagonal member 12 to be lifted more than necessary is suppressed.

  The relationship between the first position and the second position in the upper wedge member 50 of the upper connecting portion 40 will be described using the front view of the main part of FIGS. 4 and 5. FIG. 4 shows a state in which the upper connecting portion 40 is engaged with a wedge receiver disposed on the side of the wedge receiver facing the scaffolding columns 1 and 1. Specifically, the upper connecting portions 40 and 40 at both ends of the horizontal member 11 are engaged with the upper wedge receivers 3b and 3b (see FIG. 12) of the scaffolding columns 1 and 1.

  In the case of engagement between the upper wedge receivers 3b and 3b, it is necessary to extend the distance between the upper wedge receivers 50 of the upper connecting portion 40 disposed at both ends of the horizontal member 11 by a predetermined amount. Therefore, in the upper connecting portion 40 of the embodiment, the shaft support groove holes 43 that are elongated holes in the longitudinal direction are formed in the both end portions 42 of the horizontal member 11 as described above. Therefore, although the upper wedge member 50 and the diagonal member 12 are only allowed to rotate by the shaft support of the shaft support pin 45, the horizontal wedge member 50 and the horizontal member 11 can be easily moved in the horizontal direction. The angle of the diagonal member 12 with respect to the scaffolding column 1 is changed, and the position of the diagonal member 12 is also adjusted in the lower connecting portion 20 described later. The positional relationship between the upper wedge member 50 and the horizontal member 11 in FIG. 4 is the first position. In the embodiment, the angle formed between the diagonal member and the scaffolding strut when constituting the first position is 60.5 °.

  FIG. 5 shows a state in which the upper connecting portion 40 is engaged with the wedge receivers facing each other between the scaffolding columns 1 and 1. Specifically, the upper connecting portions 40, 40 at both ends of the horizontal member 11 are engaged with the upper wedge receivers 3c and 3a (see FIG. 12) of the scaffolding struts 1, 1. In the case of engagement between the upper wedge receivers 3c and 3a, the distance between the upper wedge receivers 3c and 3a of the upper connecting portion 40 disposed at both ends of the horizontal member 11 is reduced by a predetermined amount compared to the first position. It is done. Therefore, in the upper connection portion 40 of the embodiment, the upper wedge member 50 and the horizontal member 11 are positioned in the horizontal direction because of the shaft support groove holes 43 formed in both end portions 42 of the horizontal member 11 in FIG. Easy to move. The angle of the diagonal member 12 with respect to the scaffolding column 1 is changed, and the position of the diagonal member 12 is also adjusted in the lower connecting portion 20 described later. The positional relationship between the upper wedge member 50 and the horizontal member 11 in FIG. 5 is the second position. In the embodiment, the angle formed between the diagonal and the scaffolding strut when constituting the second position is 59.5 °.

  Next, the structure of the lower connecting portion and the positional relationship of engagement between the lower connecting portion and the lower wedge receiver 2 of the scaffolding column will be described with reference to FIGS. The lower connecting portion 20 of the diagonal member 12 has a first position (see FIG. 4) relative to the diagonal member 12 corresponding to the movement of the upper wedge member 50 in the first position (FIG. 4) and the second position (FIG. 5). 6) and a lower movable member 30 that can move between the second position (FIG. 7) is attached. The lower movable member 30 is provided with a lower wedge member 25 that engages with the lower wedge receiver.

  The lower connecting portion 20 connects the two main body plate portions 21 and 22 by a beam portion 24 (plate connecting portion) (see particularly FIG. 8). Then, the lower wedge member 25 is placed immediately above the beam portion 24. The lower wedge member 25 includes a lower long leg portion 26 and a lower short leg portion 27, and a lower leg portion 28 is formed between the leg portions 26 and 27. An appropriate retaining portion 29 is also provided at the tip of the lower long leg portion 26.

  6 and 7, the lower wedge receiver 2 and the beam portion 24 of the lower connection portion 20 are in contact with each other, and the lower wedge member 25 is in contact therewith. Is pressed. The lower wedge receiver 2 and the beam portion 24 are sandwiched by the lower wedge member 25, and the engagement between the lower connecting portion 20 and the lower wedge receiver is completed. In the center of the main body plate portions 21 and 22, a wedge holding portion 23 penetrating the main body plate portion is provided. Since the lower long leg portion 26 of the lower wedge member 25 is in contact with the wedge holding portion 23, the lower plate portion 25 is inserted into the main body plate portions 21 and 22 when the lower connection portion 20 and the lower wedge receiver 2 are engaged. In addition, since the inadequate displacement of the lower wedge member 25 is suppressed, the fixability of the lower wedge member 25 is increased.

  In the lower movable member 30 of the lower connecting portion 20, a support pin portion 32 is provided through the main body plate portions 21 and 22 on the opposite side to the beam portion 24 (see FIG. 8). The support pin portion 32 is engaged with a lower groove portion 31 formed at the lower end portion 16 of the diagonal member 12. The lower groove portion 31 of the diagonal member 12 can be moved through the support pin portion 32. The lower groove portion 31 of the lower movable member 30 of the embodiment is formed as a groove hole penetrating the diagonal member 12 in a U shape in front view. And in order to contact with the support pin part 32 and to get caught by the support pin part, the advance groove hole 35 and the retreat groove hole 36 are drilled in the lower groove part 31 (refer FIG. 6, FIG. 7).

  Here, FIG. 6 shows a state of engagement between the lower connecting portion 20 provided at the lower end portion 16 of the diagonal member 12 and the wedge receiver disposed on the side of the wedge receiver facing between the scaffolding columns 1 and 1. Show. In the state shown in the drawing, the lower connecting portions 20 and 20 of the diagonal members are engaged with the lower wedge receivers 2b and 2b (see FIG. 12) of the scaffold column 1.

  The selection of the lower wedge receiver 2 in FIG. 6 corresponds to the first position of the upper connecting portion 40 (upper wedge member 50) illustrated in FIG. In the case of FIG. 6, since the upper connecting portion 40 (upper wedge member 50) is already in the first position as described with reference to FIG. 4, the diagonal member 12 is disposed so as to extend diagonally between the scaffolding columns 1 and 1. It becomes. In this case, the support pin part 32 moves along the lower groove part 31, and the position where the diagonal member 12 can be made the longest is selected. Therefore, the support pin portion 32 is abutted against the advance groove hole 35 at the end of the lower groove portion 31. Accordingly, the positional relationship between the diagonal member 12 and the lower wedge member 25 is also defined. Accordingly, FIG. 6 shows the positional relationship of the first position for the diagonal member 12 corresponding to the first position of the upper wedge member 50.

  The subsequent selection of the lower wedge receiver 2 in FIG. 7 corresponds to the second position of the upper connecting portion 40 (upper wedge member 50) shown in FIG. In the case of FIG. 7, since the upper connecting portion 40 (upper wedge member 50) is in the second position as already described with reference to FIG. 5, the diagonal member 12 is arranged in a diagonal direction between the scaffolding columns 1 and 1. It becomes. In this case, the support pin portion 32 moves along the lower groove portion 31, and a position where the diagonal member 12 can be shortened is selected. Therefore, the support pin portion 32 is abutted against the receding groove hole 36 at the end of the lower groove portion 31. Accordingly, the positional relationship between the diagonal member 12 and the lower wedge member 25 is also defined. Accordingly, FIG. 7 shows the positional relationship of the second position with respect to the diagonal member 12 corresponding to the second position of the upper wedge member 50.

  FIG. 9 is a front view of the main part of the lower movable member 30A of the lower connecting part 20 according to another embodiment. In the drawing, a plurality of (two in the drawing) holding through holes 39 are provided in the lower end portion 16 of the diagonal member 12. In FIG. 9, since it becomes the 2nd position about the diagonal member 12, it is necessary to make the diagonal member 12 the shortest. Therefore, the retreat through hole 31a is selected from the holding through holes 39, and the through support pins 32a are inserted into the retreat through holes 31a and fixed to the main body plate portions 21 and 22. The receding through hole 31a is rotatable with the through support pin 32a.

  Although not shown, when the lower wedge receiver 2 of FIG. 6 is selected for the lower movable member 30A, the forward through hole 31b is selected, and the through support pin 32b is inserted therethrough, and the main body plate portions 21 and 22 are inserted. Fixed. Since the penetration support pin is attached and detached at any time, it is mainly formed from a combination of a bolt and a nut.

  Furthermore, the other Example in an upper side connection part is disclosed using FIG.10 and FIG.11. FIG. 10 is an exploded perspective view of main parts related to the upper connecting part 40X according to another embodiment. In this embodiment, the holding performance of the upper wedge member and the horizontal member is further improved. An upper jaw portion 44 and a lower jaw portion 46 are provided at the end of the end portion 42 of the horizontal member 11x, and the upper jaw portion 44 and the lower jaw portion 46 form a jaw opening 49 having a U-shape when viewed from the front. Therefore, the fixing pin 41 is accommodated in the chin opening 49.

  In the vicinity of the end portion 42 of the horizontal member 11x of the embodiment, a wedge member upper holding portion 47 and a wedge member lower holding portion 48 that are paired on the upper and lower sides of the horizontal member are provided. The wedge member upper holding portion 47 covers the upper side portion 57 of the upper wedge member 50 from the upper side, and the wedge member lower holding portion 48 covers the lower side portion 58 of the upper wedge member 50 from the lower side. As can be understood from the vertical cross-sectional view of the main portion of the upper connecting portion 40X in FIG. 11, the horizontal member 11x having the wedge member upper holding portion 47 and the wedge member lower holding portion 48 is also U-shaped in the side view sectional view. It is made. The upper wedge member 50 of this embodiment is sandwiched from the vertical direction by the horizontal member 11x.

  As described above, the upper wedge member and the horizontal member move in the horizontal direction between the first position and the second position. In particular, according to the structure of the horizontal member 11x in the upper connecting portion 40X shown in the figure, the upper wedge member 50 and the horizontal member 11x are restrained from moving in the vertical direction and the rotational direction, and rattling, and both move only in the horizontal direction.
