The bifurcated portion C13 extends from the flange portion 13B in the length direction of the brace body 11, and has two extending portions 17 facing each other in a direction perpendicular to the length direction of the brace body 11. , 18. 7 and 8, these extending portions 17 and 18 are provided at the base portion on the side of the flange portion 13B between the extending portions 17 and 18 in the connector main body 13. They are joined together by a joint 19 .

As can be seen from FIGS. 7 and 8, the upper and lower surfaces of the connecting portion 19 are tapered so as to approach each other as they extend from the flange portion 13B side in the direction in which the extending portions 17 and 18 extend. It has an inclined surface.

As shown in FIGS. 7 and 8, the bifurcated portion 13C is provided with a through-hole portion 20 penetrating in a direction perpendicular to the longitudinal direction of the brace body 11 at a location away from the flange portion 13B. Since the through-holes 20 are formed in the respective extensions 17 and 18, the forked portion 13C has two through-holes divided between the two extensions 17 and 18. 20 are provided. Further, the bifurcated portion 13C is provided with a through hole portion 21 penetrating in a direction perpendicular to the length direction of the brace body 11 at a location near the flange portion 13B. 19 is provided, the through-hole portion 21 as one hole formed continuously with the two extending portions 17 and 18 and the coupling portion 19 is formed in the connector main body. 13 (see FIG. 9, which is a cross-sectional view along line S9-S9 in FIG. 6B, and FIG. 10, which is a cross-sectional view along line S10-S10 in FIG. 5A).

As shown in FIGS. 8 and 9, the connecting pin 14 of this embodiment includes an insertion shaft portion 14A with a short dimension, an operation shaft portion 14B with a long dimension, and these insertion shafts. It has a J-shape or a substantially J-shape in plan view, which is composed of the connection portion 14C connecting the portion 14A and the operation shaft portion 14B. The insertion shaft portion 14A is removably inserted into the through-hole portion 20, and the operation shaft portion 14B is removably inserted into the through-hole portion 21, whereby the connecting pin 14 is set in the connecting device main body 13. The insertion shaft portion 14A and the operation shaft portion 14B are slidable relative to the connector body 13 in a direction perpendicular to the length direction of the brace body 11. The portion 14A and the operating shaft portion 14B are parallel to each other and extend in the sliding direction perpendicular to the length direction of the brace body 11. As shown in FIG.

As can be seen from FIGS. 7 and 8, the insertion of the insertion shaft portion 14A into the through-hole portion 20 and the insertion of the operation shaft portion 14B into the through-hole portion 21 are performed by two extensions forming the bifurcated portion 13C. Of the portions 17 and 18, the insertion is performed from the extending portion 17 side which is the connecting portion 14C side of the connecting pin 14. By this insertion, the insertion shaft portion 14A is divided into two pieces as shown in FIG. The operating shaft portion 14B reaches the through hole portion 20 of the extending portion 18 on the side opposite to the connecting portion 14C and has a longer dimension than the insertion shaft portion 14A. passes through the through-hole portion 21 and protrudes outside the extension portion 18 . The coil spring 15, which is an elastic member as described above, is fitted to the outer peripheral portion of the operating shaft portion 14B projecting outside the extension portion 18 in this way, and one end of the coil spring 15 in the length direction is fitted. The other end of the coil spring 15 in the length direction is a plate-shaped spring receiving member that is fitted to the outer circumference of the tip of the operating shaft portion 14B. 22, and is prevented from coming off from the tip of the operating shaft 14B by a fixing pin 23 press-fitted into a hole formed in the tip of the operating shaft 14B.

Since the coil spring 15 arranged between the base of the bifurcated portion 13C and the spring bearing member 22 is compressed in this way, the tip of the insertion shaft portion 14A extends to the connecting pin 14. An elastic biasing force of the coil spring 15 is constantly applied to maintain the state of being inserted forwardly into the through-hole portion 20 of the portion 18 . Further, as shown in FIG. 11, when the operator applies a pushing operation force to the distal end portion of the operation shaft portion 14B against the elastic biasing force of the coil spring 15, the connecting pin 14 is moved to the insertion shaft portion 14A. slides in a retreating direction in which the distal end portion of the extending portion 18 escapes from the through hole portion 20 of the extending portion 18 .

As shown in FIGS. 9 and 11, the base of the bifurcated portion 13C is provided with a recess 24 formed with a depth from the side of the extension 18, and the recess 24 is located at the base of the bifurcated portion 13C. Since the diameter is larger than that of the through-hole portion 21 provided in the above-described through-hole portion 21 and is formed coaxially with this through-hole portion 21, the recessed portion 24 also serves as a part of the through-hole portion 21. ing. The bottom portion 24A of the recess 24 is in contact with one end of the coil spring 15 in the length direction. The length dimension can be large. As a result, when an operator applies a pushing force against the elastic biasing force of the coil spring 15 to the distal end portion of the operating shaft portion 14B of the connecting pin 14, the coil spring 15 can be compressed and deformed sufficiently. Therefore, the connecting pin 14 is slidably moved in the backward direction until the tip of the insertion shaft portion 14A escapes from the through hole portion 20 of the extension portion 18 and reaches the through hole portion 20 of the extension portion 17 sufficiently. Can be slid in amount.

In order to connect both ends of the brace 10 in the length direction according to the present embodiment to the two upper and lower horizontal members 4 as described in FIG. As shown in FIG. 11, an operator pushes the distal end of the operating shaft portion 14B of the connecting pin 14 against the elastic biasing force of the coil spring 15 for each of the connecting devices 12 which are connected to each other. As a result, the distal end portion of the insertion shaft portion 14A of the connecting pin 14 is slid in the retreating direction of escaping from the through hole portion 20 of the extension portion 18, and thereafter, is attached to the main body 4A of the horizontal member 4 as a part of the horizontal member 4. The projecting piece portion 4C provided above is inserted between the two extending portions 17 and 18 forming the bifurcated portion 13C. Next, when the pushing operation force acting on the distal end portion of the operating shaft portion 14B of the connecting pin 14 is released, the insertion shaft portion 14A of the connecting pin 14 slides forward due to the elastic biasing force of the coil spring 15. As shown in FIG. 12, the portion 14A is inserted into a hole 25 provided in the protruding portion 4C so that each of the longitudinal ends of the brace 10 is provided in the connector 12. It will be connected to the upper and lower two horizontal members 4 via the connecting pins 14 provided.

Since the forward sliding force is always applied to the insertion shaft portion 14A after this due to the elastic biasing force of the coil spring 15, both ends in the length direction of the brace 10 are connected to the two upper and lower horizontal members 4. state can be maintained.

When inserting the protruding piece 4C between the two extensions 17 and 18 forming the bifurcated portion 13C, the flanges of the two extensions 17 and 18 are inserted as described above. The upper and lower surfaces of the connecting portion 19 that connects the base portion of the portion 13 side are tapered and inclined toward each other as they extend in the extending direction of the extending portions 17 and 18 from the flange portion 13B side. Even if the projecting piece 4C comes into contact with the connecting portion 19, the projecting piece 4C can be more reliably and easily inserted between the extending portions 17 and 18 due to the guiding action of these inclined surfaces. can do.

In addition, in order to release both ends of the brace 10 in the length direction from the connection with the two upper and lower horizontal members 4, the operator must move the tip portion of the operation shaft portion 14B of the connection pin 14 for each connection tool 12. is pushed against the elastic biasing force of the coil spring 15, the insertion shaft portion 14A retreats and escapes from the hole 25 of the projecting piece portion 4C. The operation of extracting the projecting piece portion 4C from between 17 and 18 can be performed.

As described above, at the longitudinal ends of the brace 10 according to the present embodiment, the holes 25 provided in the horizontal members 4, which are elongated members for constructing the shoring, which is a temporary structure, are provided. A connecting pin 14 inserted removably and a coil spring 15 serving as an elastic member for elastically biasing the connecting pin 14 in the forward direction in which the connecting pin 14 is inserted into the hole 25 are provided. A configured link 12 is provided so that the operation for linking the longitudinal ends of the brace 10 to the horizontal member 4 is accomplished by inserting the link pin 14 into the hole 25 so that the link pin 14 can be coiled. After retracting against the elastic biasing force of the spring 15, the connecting pin 14 can be advanced by the elastic biasing force of the coil spring 15 and inserted into the hole 25. Therefore, this connecting work can be shortened. It will become easier in time.

In addition, the connecting pin 14 according to the present embodiment includes an insertion shaft portion 14A that is inserted into the hole 25 by being advanced by the elastic biasing force of the coil spring 15, and in order to escape the insertion shaft portion 14A from the hole 25, The operating shaft portion 14B is operated to retract the insertion shaft portion 14A against the elastic biasing force of the coil spring 15. The operation for retracting by pressing can be easily performed by operating the operating shaft portion 14B instead of operating the insertion shaft portion 14A.

The operation for retracting the insertion shaft portion 14A against the elastic biasing force of the coil spring 15 may be performed by pulling the connecting portion 14C of the connecting pin 14. FIG.

In addition, the connector 12 according to the present embodiment includes a connector body 13 that is coupled to the end portion of the brace body 11, and the connector pin 14 is attached to the connector body 13 in the longitudinal direction of the brace body 11. The connecting pin 14 has an insertion shaft portion 14A and an operation shaft portion 14B extending parallel to the sliding direction. are connected by the connecting portion 14C, the connecting pin 14 is perpendicular to the length direction of the brace body 11, compared to the case where the connecting pin is linear extending in the above-described sliding direction. can be shortened in the direction forming the , and thus the entire coupling 12 including the coupling pin 14 can be miniaturized.

In addition, in this embodiment, one longitudinal end of the coil spring 15 fitted to the outer periphery of the operating shaft portion 14B of the connecting pin 14 is connected to the base of the forked portion 13C provided in the connector main body 13. The other end of the coil spring abuts on the spring bearing member 22 provided on the operating shaft portion 14B, whereby the insertion shaft portion 14A is pushed into the connecting pin 14 by the elastic biasing force of the coil spring 15 as described above. A forward force is applied to insert the coil spring 15 into the hole 25, and the connector main body 13 is provided with a recess 24 into which a part of the coil spring 15 in the length direction is inserted. The length dimension of the natural length can be increased by the depth of the recess 24 . Therefore, the longitudinal end of the brace 10 connected to the horizontal member 4 is removed from the horizontal member 4 by inserting the insertion shaft portion 14A of the connecting pin 14 into the hole 25 of the projecting piece 4C. In some cases, the amount of movement for retreating the insertion shaft portion 14A against the elastic biasing force of the coil spring 15 is determined by the two extending portions 17 and 18 forming the forked portion 13C of the connector main body 13. Of these, the insertion shaft portion 14A can be moved out of the through-hole portion 20 of the extension portion 18, and the distal end portion of the insertion shaft portion 14A can reach the through-hole portion 20 of the extension portion 17 by a large amount of movement. This eliminates the work of removing the ends of the braces 10 connected to the horizontal members 4 in the length direction from the horizontal members 4 and the work of connecting the ends of the braces 10 in the length direction to the horizontal members 4 . It can be implemented more reliably.

Further, in this embodiment, the coupler main body 13 has two extending portions 17 and 18 each extending in the longitudinal direction of the brace main body 11 with a space therebetween in the sliding direction of the connecting pin 14 . A through hole portion 20 into which the insertion shaft portion 14A of the connecting pin 14 is slidably inserted is provided in these extension portions 17 and 18, and the hole 25 into which the insertion shaft portion 14A is inserted is , is formed on a plate-like protruding piece 4C provided on the horizontal member 4, and by inserting this protruding piece 4C between the two extending portions 17 and 18, the insertion shaft portion 14A is inserted into the hole. 25, the insertion shaft portion 14A can be guided through the through-hole portions 20 provided in the two extension portions 17 and 18 and can be slid stably.

Further, after the longitudinal end of the brace 10 is connected to the horizontal member 4 by inserting the insertion shaft portion 14A of the connecting pin 14 into the hole 25 formed in the protruding portion 4C, the shoring is performed. When an axial force such as a tensile force or a compressive force in the length direction of the brace 10 acts on the brace 10 due to an acting lateral load or the like, the through holes 20 provided in the two extensions 17 and 18 Since the insertion shaft portion 14A is supported at two points in the axial direction, this axial force can be effectively supported by the couplings 12 provided at the ends of the brace 10 in the longitudinal direction.

Furthermore, each of the connecting devices 12 provided at both ends in the length direction of the brace 10 is composed mainly of a connecting device main body 13, a connecting pin 14, and a coil spring 15. 2, in these connecting tools 12, the forward sliding direction of the connecting pin 14 for inserting the insertion shaft portion 14A into the hole 25 of the projection portion 4C of the horizontal member 4 is the same direction. Therefore, the operator who performs the work for connecting both ends of the brace 10 in the length direction to the two horizontal members 4 above and below performs this work from the same side with respect to these horizontal members 4.
