Description

The present invention relates to a suspension scaffold suspended from a beam member such as a steel frame in a building.

2. Description of the Related Art Conventionally, there is known a suspension scaffold in which a gondola-shaped scaffold structure is suspended on a beam member such as a steel frame in a building, and is used for work at a high place.

In general, a suspension mechanism for a suspension scaffold is configured by a support arm that extends from the upper end of the support structure's column so as to cross the upper surface of the beam member, and a locking means provided on the support arm. The locking means is configured to be detachably locked to the locking edge of the beam member.

The locking means is slidably and fixedly mounted in the longitudinal direction of the support arm, so that even if the width of the beam member at the site is different, the locking means is engaged with the beam member accordingly. It is comprised so that it can be latched to a stop edge part.

Japanese Patent Laid-Open No. 2015-212477 Japanese Patent No. 3590360

The suspension mechanism proposed in the above-mentioned patent document is such that the support arm is formed of a screw rod, and a locking means made of a cylindrical member provided with a claw fitting is slidably fitted to the screw rod so that the tail end of the screw rod The wing nut is configured to be screwed.

Therefore, according to such a suspension mechanism, the engaging means is moved forward along the screw rod in a state where the support arm made of the screw rod is placed in a transverse posture on the upper surface of the beam member. The claw fitting of the locking means is locked to the locking edge of the beam member, and in this state, the wing nut is fastened so that the locking means does not move backward, so that the scaffold structure is suspended from the beam member. It is possible to make it.

Therefore, in order to fix the locking means so that it does not move backward with the claw fitting of the locking means being locked to the locking edge of the beam member, the wing nut is engaged from the tail end of the screw rod. There is a problem that a long distance to reach the stop means must be screwed, and the operation is complicated and requires a long time to complete the operation.

By the way, in the case of the technique proposed by the patent document, the suspension mechanism will not fall off the beam member unless the wing nut is loosened. However, if the wing nut is loosened, the locking means slides along the screw rod, the claw fitting is moved backward from the locking edge of the beam member to release the locked state, and the scaffold component is There is a risk of falling from the beam member.

In order to solve such a problem, for example, an insertion hole may be arranged in a row at a predetermined interval in the support arm, and a fixing pin provided in the locking means may be configured to be inserted through the insertion hole. As a result, the locking means can be securely fixed to the support arm.

However, in this case, since the fixing position of the locking means is limited to the position of the insertion hole, in the present situation where the width dimension of the beam member varies from site to site, the locking means must always be engaged with the locking edge of the beam member. This creates a new problem that cannot be stopped.

For this reason, this invention makes it a subject to provide the suspension scaffold provided with the suspension mechanism which solved the said problem.

Therefore, the present invention is configured as means, with respect to the scaffold structure suspended on the work side, with both sides of the beam member in the building as the working side and the non-working side, respectively, and the upper end of the column of the scaffold structure A support arm that extends from the section so as to cross the upper surface of the beam member, and a locking device that is mounted on the support arm and removably engages with a locking edge on the non-working side of the beam member In the suspension scaffold provided with a suspension mechanism constituted by the support arm, the support arm has a fixed element lined up at a predetermined interval in the longitudinal direction, and the locking device is attached to the fixed element of the support arm. A fixed body having a fixing means that is selectively fixed to the locking member, and a locking body having a locking portion that is locked to a locking edge of the beam member. The body connects the locking part to each other through the connecting means. Kigakari Tomeen lies in comprising linked to freely and fixable moving forward and locking member in a direction to retract against the unit.

In a preferred embodiment of the present invention, the fixed body is slidably mounted on the support arm, and the fixing element is constituted by an insertion hole that crosses the support arm, and the insertion member is detachably inserted into the insertion hole. The fixing means is constituted by a fixing pin to be inserted.

Preferably, the connecting means gradually moves the locking body downward when the locking body moves forward toward the locking edge of the beam member with respect to the fixed body. The locking body abuts against at least one of the support arm and the fixed body from below, thereby preventing the locking body from moving backward along the inclined guide path. Locking means are provided.

According to the first or second aspect of the present invention, the locking device 11 is provided with a fixing means 24 that is selectively fixed to the fixing elements 15 arranged at intervals on the support arm 10. Since the body 17 and the locking body 18 provided with the locking portion 18a locked to the locking edge 1b of the beam member 1, the fixing means 24 is fixed to the fixing element 15, The locking device 11 can be fixed to the support arm 10 so that it cannot move and cannot be detached. The locking device 11 is fixed so as to be immovable immediately after the fixing body 17 is moved along the support arm 10 to a predetermined position and then the fixing means 24 provided on the fixing body 17 is fixed to the fixing element 15. As a result, the speed and ease of work are greatly improved as compared with the conventional screw rod and wing nut configuration.

At this time, the locking body 18 is configured to be movable back and forth and fixed toward the locking edge 1b of the beam member 1 with respect to the fixed body 17 by the connecting means 27. Even when the locking portion 18a and the locking edge portion 1b are not locked to each other due to the interval pitch P and a gap S is generated, the locking portion 18a is moved by moving only the locking body 18. There is an advantage that can be suitably locked to the locking edge 1b.

According to the third aspect of the present invention, the connecting means 27 is an inclined guide path that gradually moves downward when the locking body 18 is moved in the forward direction toward the locking edge 1b. 30, the locking body 18 abuts the support arm 10 or the fixed body 17 from below when trying to move the locking body 18 in the backward direction along the inclined guide path 30. Since the locking means 32 for preventing the movement in the backward direction is provided, even if the locking state of the locking body 18 by the connecting means 27 is lost, the locking portion 18a is separated from the locking edge 1b. There is an effect that can be surely prevented and a safe locking state can be realized.

The suspension mechanism 3 includes a support arm 10 extending so as to cross the upper surface of the beam member 1 from the upper end portion of the support 5a of the first frame 5 in the scaffold structure 2, and the support arm 10 It is comprised by the latching device 11 mounted.

The beam member 1 is generally formed of a steel frame and is typically formed of an H-shaped steel. Of the edges on both sides of the upper surface, the edge facing the working side X1 is used as the fixed edge 1a. The suspension mechanism 3 can be fixedly locked by using the edge facing the non-working side X2 as the locking edge 1b.

At this time, since the beam member 1 has a different width dimension W depending on the site, the suspension mechanism 3 is configured to be able to fix the locking device 11 to the beam member 1 corresponding to the different width dimension W. Has been.

The bracket 14 is pivotally connected to the bracket 14 via a pivot 14. Therefore, as shown in FIG. 7, the support arm 10 is folded so as to overlap along the support column 5 a when the scaffold structure 2 is folded.

The arm body 12 of the support arm 10 has fixing elements 15 arranged in a row at predetermined intervals in the longitudinal direction, and in the case of the illustrated embodiment, the fixing element 15 is configured by an insertion hole 15 a that crosses the arm body 12. ing. In addition, the tail end portion (free end portion) of the arm body 12 is provided with a retaining means 16 made of a plate fixed to the side surface of the arm body 12 by bolts and nuts.

The locking device 11 includes a fixed body 17 that is slidably mounted on the arm body 12, and a locking portion that is connected to the fixed body 17 and is locked to the locking edge 1 b of the beam member 1. It is comprised by the latching body 18 provided with 18a.

Therefore, as shown in FIG. 3, the suspension mechanism 3 supports the locking device 11 in a state where the fixed edge portion 1 a of the beam member 1 is in contact with the claw portion 13 a of the claw fitting 13 of the support arm 10. By sliding along the arm 10 and fixing it at a predetermined position, the locking edge portion 1b of the beam member 1 is locked and fixed by the locking portion 18a.

As shown in FIG. 4, the fixed body 17 is formed by cutting an extrusion molding material such as aluminum, and is inserted in an H-shaped section so as to be slidably extrapolated to the arm body 12. A slider 20 having a path 19, a lateral groove-shaped receiving portion 21 extending on a side portion of the slider 20, and a connecting plate portion 22 suspended from the lower surface of the slider 20 are provided.

A substantially U-shaped holding bracket 23 is fixed to the receiving portion 21 of the fixing body 17, and the holding bracket 23 holds a fixing means 24 including a fixing pin 24 a penetrating through the insertion path 19. ing. The fixing pin 24 a is elastically biased by a spring 25 in a direction penetrating the insertion path 19, picks up the head 24 b that protrudes outside the holding bracket 23, and pulls out against the spring 25. By moving in the direction, the distal end portion of the fixing pin 24 a can be escaped from the insertion path 19.

The locking body 18 forms a groove portion 26 into which the connecting plate portion 22 of the fixed body 17 is slidably inserted. The locking body 18 is connected to the beam member between the connecting plate portion 22 and the groove portion 26. A connecting means 27 is provided to be movable and fixed in a direction of moving forward and backward with respect to one locking edge 1b.

The connecting means 27 guides the first bolt 28a and the first nut 28b, the second bolt 29a and the second nut 29b, and both the bolts 28a and 29a provided in the locking body 18 through the groove 26. Is formed by an inclined guide path 30 formed by a long hole formed in the connecting plate portion 22, and the inclined guide path 30 is engaged with the beam member 1 as shown by an arrow F in FIG. 4. With respect to the forward movement direction toward the edge 1b, it is formed so as to be gradually inclined downward. In the illustrated embodiment, the first bolt 28a is a butterfly bolt.

A jaw member 31 made of a substantially L-shaped metal plate is fixed to the end of the locking body 18 in the forward movement direction F, and the locking portion 18a is formed by the standing portion of the jaw member 31. The latching portion 18b is formed by the lateral tongue piece.

Locking means 32 is provided at the end of the locking body 18 in the backward movement direction (the direction opposite to the forward movement direction F). The lock means 32 includes a fixing nut 33 fixed to the locking body 18 and a lock bolt 34 including a butterfly bolt screwed upward from the lower side of the fixing nut 33. In addition, it is preferable that a locking spring 35 made of a compression spring is interposed between the head of the lock bolt 34 and the fixing nut 33.

(Operation of the suspension mechanism)
The locking device 11 inserts the connecting plate portion 22 of the fixed body 17 into the groove portion 26 of the locking body 18, and causes the first bolt 28 a and the second bolt 29 a to pass through the groove portion 26 and the inclined guide path 30. The first nut 28b and the second nut 29b are screwed to the insertion ends, respectively, so that the locking body 18 is connected to the fixed body 17 for use.

Then, after inserting the arm body 12 of the support arm 10 into the insertion path 19 of the fixed body 17, the retaining means 16 is fixed to the tail end portion of the arm body 12, and the support arm 10 and the locking device 11 are assembled. As shown in FIG. 1, the scaffold structure 2 is suspended from the beam member 1 by the suspension mechanism 3 configured as described above.

With the locking device 11 positioned near the tail end of the support arm 10, the claw portion 13 a of the claw fitting 13 at the base end portion of the support arm 10 is fixed to the fixed edge 1 a of the beam member 1 as described above. After the support arm 10 is placed on the upper surface of the beam member 1 in a transverse state, the locking device 11 is locked to the locking edge 1 b of the beam member 1.

As shown in FIG. 5B, the fixed body 17 can be slid along the arm body 12 of the support arm 10 by retracting the fixing pin 24 a from the insertion path 19. Then, as shown in FIG. 5C, the fixing body 17 can be fixed to the arm body 12 by passing the fixing pin 24 a through the insertion path 19 and passing through the insertion hole 15 a of the arm body 12. . Therefore, as shown in FIG. 5 (A), by selecting the insertion hole 15a arranged in the arm body 12, the fixing pin 24a is positioned at the position where the locking portion 18a is closest to the locking edge 1b. It is inserted through the insertion hole 15a.

In this state, the fixing body 17 is fixed to the arm body 12 so as not to move and to drop off because the fixing pin 24a penetrates both the slider 20 and the arm body 12. The fixing pin 24a does not necessarily have to be configured to pass therethrough. In short, any configuration may be used as long as the fixing means 24 of the fixing body 17 is fixed to the fixing element 15 of the arm body 12.

By the way, as shown in FIG. 5A, the fixing elements 15 including the insertion holes 15a are arranged in the longitudinal direction of the arm body 12 at a pitch P of a predetermined interval. In the state fixed to 15, the locking part 18a and the locking edge 1b may not be locked to each other, and a gap S may be generated.

Therefore, as shown in FIG. 6A, when the first bolt 28a and the second bolt 29a are loosened, the locking body 18 can move in the forward direction F along the inclined guide path 30. The locking body 18 is moved to a position where the locking portion 18a abuts and locks with the locking edge 1b, and after the movement, the first bolt 28a and the second bolt 29a are fastened, whereby the locking body 18 is secured. Is fixed to the fixed body 17.

At this time, with respect to the two bolts of the first bolt 28a and the second bolt 29a, a loose fastening bolt may be constituted by one of the first bolts 28a formed of a butterfly bolt. In this case, the 2nd volt | bolt 29a comprises the support means loosely inserted by the inclination guide path 30, and cooperates with the 1st volt | bolt 28a and supports the latching body 18 to the inclination guide path 30 so that a movement is possible. As a result, only the first bolt 28a needs to be relaxed or fastened, and the locking body 18 can be moved and fixed quickly and easily.

Further, after the locking body 18 is fixed to the fixed body 17 by the fastening bolt 28a in a state where the locking portion 18a is in contact with the locking edge 1b, as shown in FIG. The lock bolt 34 that constitutes is screwed upward against the loosening prevention spring 35, and the tip of the lock bolt 34 is brought into contact with the lower surface of the arm body 12.

As a result, even if the fastening bolt 28a is loosened and the locking body 18 tries to move in the backward direction as shown by the arrow R in the drawing, the moving direction is set to the oblique upward direction along the inclined guide path 30. Therefore, it is received by the lock bolt 34 and the backward movement is prevented. Accordingly, the locking portion 18a is not separated from the locking edge portion 1b, and the locked state is not released.

In the case of the illustrated embodiment, the lock bolt 34 is configured to prevent the locking member 18 from moving backward by contacting the lower surface of the arm body 12, but the lock bolt 34 contacts the fixed body 17. You may comprise so that it may be made. For example, in the illustrated configuration, the fixing nut 33 may be fixed to the side portion of the locking body 18, and the upper end of the lock bolt 34 may be in contact with the lower surface of the receiving portion 21 of the fixing body 17. However, it is possible to obtain a locking effect that prevents the locking member 18 from moving backward.

As a result, the suspension mechanism 3 ensures the safety of the worker who performs the work at a high place while riding on the scaffolding structure 2 by enabling a reliable locking and fixing state with respect to the beam member 1.

By the way, since it is common to perform the high-altitude work while moving along the longitudinal direction of the beam member 1, after the predetermined work is finished, the locking device 11 is connected to the locking edge of the beam member 1. In a state of being separated from the portion 1b, the suspension mechanism 3 is moved in the longitudinal direction of the beam member 1 together with the scaffold component 2, and the locking device 11 is again locked to the locking edge 1b of the beam member 1, Work at a high altitude.

In this case, the locking body 18 is moved in the backward direction R by loosening the fastening bolt 28a after the locking bolt 34 of the locking means 32 is retracted from the lower surface of the arm body 12 by the reverse procedure. Then, as shown in FIG. 5A, if the locking portion 18a is moved away from the locking edge portion 1b, the suspension mechanism 3 including the support arm 10 can be moved along the upper surface of the beam member 1. After the movement, the locking portion 18a may be locked again with the locking edge 32 by locking the locking portion 18a again with the same procedure as described above.

Thus, even when the suspension mechanism 3 is moved along the beam member 1, the fixing pin 24 a of the fixing body 17 may be left in the insertion hole 15 a, and the entire locking device 11 is supported by the support arm. There is no need to move a large amount above 10. In particular, as shown in FIG. 5A, by forming the interval pitch P of the insertion holes 15a densely, the latching portion 18a can be placed below the latching edge portion 1b even while the suspension mechanism 3 is moving. Thus, the support arm 10 can be prevented from moving upward away from the beam member 1, and the scaffold structure 2 together with the suspension mechanism 3 can be prevented from falling from a high place. There are advantages.

(Other configurations)
As described above, as shown in FIG. 7, the scaffold component 2 can be folded from the gondola form so that the work floor 4 and the second frame 6 overlap each other toward the first frame 5. The support arm 10 of the suspension mechanism 3 is also folded so as to be superposed along the column 5a. Furthermore, the skirting board 9 of the work floor 4 is folded inside the scaffolding frame 4b.
