Among the shorings, there is a wedge-clamping type shoring in which a wedge member or the like is used to connect other structural members to a post (see, for example, Patent Document 1).

FIG. 7 is a schematic front view showing an example of conventional wedge-clamping type shoring (hereinafter simply referred to as "shoring") disclosed in Patent Document 1 above. According to this figure, the shoring 31 includes, for example, jacks 32 arranged side by side on the foundation B, supports 33 connected to the jacks 32 and extending in the vertical direction, tie members 34 extending in the horizontal direction, and diagonally extending and an extending brace 35 .

FIG. 8 is a diagram showing a connection structure between the brace 35 and the strut 33 in the shoring 31. As shown in FIG. The brace 35 is formed by locking a locking member 37 on a holder 36 formed on the support 33 and by inserting and fixing a clamping member 38 corresponding to a wedge between the holder 36 and the locking member 37 . connected to

According to this shoring 31, when the brace 35 is connected to the strut 33, the field worker needs to drive the clamping member 38 with a hammer or the like. Therefore, there is a problem that the work of connecting the braces 35 and the struts 33 is troublesome.

Another example of conventional shoring is shown in FIG. According to this figure, another shoring 41 is similar in its basic construction to the shoring 31 shown in FIG. different in that

As shown in FIG. 10, the wedge-type clamp 45 is provided at the end of the brace 42 and is composed of a clamp movable portion 46, a clamp fixed portion 47, and a wedge 48. As shown in FIG. When the brace 42 is connected to the post 43, the post 43 is gripped by the clamp movable portion 46 and the clamp fixed portion 47, and the wedge 48 is tightened between the clamp movable portion 46 and the clamp fixed portion 47. Brace 42 is connected to strut 43 .

According to the other shoring 41, the field worker needs to drive the wedge 48 with a hammer or the like when connecting the brace 42 to the support 43, as with the shoring 31 shown in FIG. Therefore, the clamp movable portion 46 and the clamp fixed portion 47 may deviate from the desired gripping positions (see arrow S in FIG. 10), which may cause the supporting force of the shoring 41 to be impaired. In addition, since the site worker drives the wedge 48 with a hammer or the like, there is a problem that the work of connecting the brace 42 and the support 43 is time-consuming, like the shoring 31 shown in FIG.

In FIG. 2, scaffolding boards, braces 15, and the like, which will be described later, are omitted.

A plurality of flanges 7 are formed on each post 3 at predetermined intervals in the height direction (see FIGS. 2 and 3), and these flanges 7 allow other constituent members, for example, wedge members (see FIG. 3). ) or the like is used to tighten the support column 3 . In addition, through-holes 8 are formed in the column 3 at desired positions in the vicinity of its upper end and in the vicinity of its lower end. The through holes 8 are for connecting braces 15, which will be described later.

In this basic structure, a plurality of horizontal tethers 10 (referred to as "lower horizontal tethers 10") are provided so as to connect adjacent struts 3 at their lower portions. Moreover, in the upper part of the basic structure, a horizontal connecting member 11 (referred to as "upper horizontal connecting member 11") is provided so as to connect the adjacent struts 3 to each other. The upper horizontal tie member 11 is provided at a predetermined interval (for example, one layer) from the lower horizontal tie member 10 in the height direction. Each of the horizontal connecting members 10 and 11 has a main body portion 12 formed in a pipe shape, and connecting members 13 for connecting to the flanges 7 of the struts 3 are connected to both ends thereof.

A plurality of scaffolding boards (not shown) extending horizontally are installed on each of the horizontal tethers 10 and 11 . The scaffolding boards are installed by hooks (not shown) formed at the ends of the scaffold boards being hung over the horizontal tethers 10 and 11 .

A diagonally extending brace 15 is provided inside a frame-shaped region surrounded by the two struts 3, the lower horizontal tie member 10 and the upper horizontal tie member 11 in the basic structure. The brace 15 has an elongated main body portion 16 and U-shaped portions 17 provided at both ends of the main body portion 16 and formed in a substantially U-shaped cross section.

The U-shaped portion 17 is formed by being slightly bent with respect to the main body portion 16, and the bending directions of the U-shaped portions 17 are opposite to each other. As shown in FIG. 3, the U-shaped portion 17 has a pair of side wall surface portions 18 facing each other, and each side wall surface portion 18 is formed with a through hole 19 passing therethrough in the thickness direction thereof. These through holes 19 are for connecting the struts 3 . A mounting pin 21 is connected to one side of the side wall portion 18 via a chain 20 .

The body portion 16 of the brace 15 is composed of two cylindrical members with different diameters, the inner member being slidable inside the outer member. Thereby, the overall length of the braces 15 can be adjusted, for example, the length of the braces 15 can be adjusted according to the interval between the adjacent struts 3 .

As shown in FIG. 2(a), one end of the brace 15 (the upper end in the figure) is connected to one of the struts 3 (the right side in the figure) slightly above the basic structure. The other end (lower end in the figure) of the brace 15 is connected to the other strut 3 (left side in the figure) slightly below the basic structure.

When the brace 15 is connected to the strut 3 (see arrow P in FIG. 3), a field worker aligns the through hole 8 of the strut 3 with the through hole 19 of the U-shaped portion 17 of the brace 15. 4, the mounting pin 21 is inserted into the through holes 8 and 19 (see arrow T).

A horizontally extending second handrail 23 is fastened between the flanges 7 one below the flange 7 to which the first handrail 22 is fastened. These first and second handrails 22 and 23 are formed to avoid interference with the brace 15 to the outside. The first and second handrails 22, 23 are for preventing the site worker from falling from the scaffold board.

Further, a flat baseboard 24 is provided around the scaffolding boards (not shown) arranged on each of the horizontal tethers 10 and 11 . The baseboard 24 is for preventing the fall of scaffolding members, tools, etc. during the work of field workers, for example. In this embodiment, since the lower end of the brace 15 is connected to the other support column 3 instead of the lower horizontal tether 10, the scaffolding board can be placed on the plane surrounded by the lower horizontal tether 10 without any gap. can be placed. Therefore, in this case as well, scaffolding members, tools, and the like can be prevented from falling.

As described above, the braces 15 are connected obliquely between the adjacent struts 3, and the braces 15 and the struts 3 are connected by the mounting pins 21 passing through the through holes 8 and 19 formed in both. Therefore, field workers can easily connect the braces 15 to the struts 3 . Therefore, the workability at the time of connection can be improved, and the assembling work time of the shoring 1 can be shortened.

In the conventional configuration, wedges and wedge-type clamps were used to connect the braces and the struts, and it was necessary to drive the wedges with a hammer or the like, and there was a problem that the connection work was troublesome. According to the shoring 1, since the wedge itself is not used, these problems can be resolved. Moreover, since the clamp is not used, it is possible to avoid the problem that the clamp deviates from the holding position.
