Description

  The present invention relates to a baseboard for a scaffold, and more particularly to a baseboard erected along a side edge of a footboard of a scaffold.

  When constructing various structures such as buildings such as apartment buildings and office buildings, structures such as bridge piers, etc., it is common to tentatively install scaffolding around the buildings. As a scaffold, a number of pillars are set up at predetermined intervals, and a horizontal member constituting a scaffold in the depth direction of the scaffold is spanned between the two pillars or is cantilevered on one pillar. It is well known that a tread (also called a scaffold) is bridged between horizontal members.

  By the way, in the scaffolding, there is a case where a baseboard is erected along a side edge portion of a tread so that a building part, a working tool, and the like are not accidentally dropped from the tread. Various skirting boards have been devised from the past. Among them, as disclosed in Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2009-275348), the gap between the scaffolding strut and the tread board is included. Some of the mounting angles are variable so that they can stand up along the side edge of the treadle even if the dimensions are different. Below, the skirting board disclosed in Patent Document 1 will be described using the words and symbols of Patent Document 1.

  A skirting board 1 disclosed in Patent Document 1 is attached to a safety handrail 5 assembled to a pedestal 9 of a building frame 12 by skirting board mounting brackets 3 and 4. The skirting board 1 is configured such that the mounting angle with respect to the scaffolding is variable by rotating the skirting board body 2 pivotally attached to the skirting board mounting brackets 3 and 4 with respect to the baseboard mounting brackets 3 and 4. It is configured. Further, the skirting board 1 has an angle / posture holding means 8, and the angular posture holding means 8 holds a required angular posture of the baseboard body 2.

  Here, the angle posture holding means 8 has a rod 25 supported so as to be slidable in the longitudinal direction of the skirting board main body 2, and locking pins 26 and 27 provided at both ends of the rod 25. Then, the rod 25 is slid to selectively lock the locking pins 26 and 27 at both ends in any of the plurality of angle changing pin holes a, b, and c provided in the base metal mounting brackets 3 and 4. By doing so, the angular posture of the skirting board body 2 can be adjusted in a plurality of stages and held at a required angular posture.

  In the skirting board mentioned above, after attaching a safety handrail to a scaffolding, it must be attached to this safety handrail, making the safety handrail an essential requirement.

  In addition, in the above-mentioned skirting board, when the skirting board main body is held at a required angle posture when being attached to the scaffolding, or when the skirting board main body inclined when being detached from the scaffolding is changed to an upright state, the rod is slid. The locking pin must be inserted and removed from the angle changing pin hole, which is complicated.

  The present invention has been made in view of the above circumstances, and provides a skirting board that can be attached to a scaffolding column without a safety handrail and that can easily change the angular posture of the skirting board body. Is an issue.

The main means taken by the present invention to solve the above problems are as follows:
"A frame having a pair of left and right vertical bars and a horizontal bar horizontally disposed between the vertical bars,
A fixture provided on the left and right of the frame, and fixed to a supporting column of the scaffold;
A skirting board main body disposed between the vertical bars and having an upper portion rotatably supported by the vertical bars so as to be inclined with respect to the frame body;
A locking pin provided on the frame,
An upright holding locking portion that is provided on the baseboard main body and is held by the locking pin and holds the position of the baseboard main body with respect to the frame in an upright state;
A connecting member having a long hole through which the locking pin is inserted and rotatably connected to a lower portion of the baseboard body;
A locking portion for maximum inclination holding provided at one end of the elongated hole, and held in a state where the posture of the baseboard body with respect to the frame body is inclined to the maximum by being locked by the locking pin;
Provided between both ends of the long hole, and held by the locking pin, the posture of the baseboard body with respect to the frame body is held in a midway state from an upright state to a maximum inclined state. Scaffolding for a scaffold characterized by having a locking portion for holding an intermediate slope ”
It is.

  In the skirting board having the above-described configuration, the frame is provided with a fixture that is fixed to the scaffolding column, and the fixture can be attached to the scaffolding column without a safety handrail.

  Further, the skirting board main body is rotated with respect to the vertical crosspiece of the frame body to be maximally inclined from a state standing upright with respect to the frame body (hereinafter referred to as “upright state”) (hereinafter referred to as “maximum inclination state”). However, in the upright state, the upright holding locking portion of the skirting board main body is locked to the locking pin of the frame body, so that it is held in the upright state. And in the state where the baseboard body is inclined, in the maximum inclination state, the maximum inclination holding locking portion of the long hole of the connecting member is locked to the locking pin of the frame, so that the baseboard body is held in the maximum inclination state. In an intermediate state from the upright state to the maximum inclined state (hereinafter referred to as “intermediate inclined state”), the locking portion for holding the intermediate portion of the long hole of the connecting member is locked to the locking pin of the frame body. Thus, it is held in an inclined state on the way. Therefore, the skirting board main body can be operated by a simple operation such as releasing the locking of the upright holding locking part, the maximum tilting holding locking part or the mid-tilt holding locking part and the locking pin and rotating the skirting board main body. The angle and posture can be changed.

  Furthermore, the angle / posture adjustment of a plurality of stages of the baseboard body including the halfway inclined state from the upright state to the maximum inclined state can be realized by a compact structure with a single locking pin.

  In addition, the mid-tilt holding latching portion is not limited to being provided at one location between both ends of the long hole of the connecting member, and is provided at a plurality of locations between the upright state and the maximum tilted state. You may enable it to implement | achieve the halfway inclination state of two steps or more.

In the means described above,
The upper part of the baseboard body is supported by the vertical beam so as to be rotatable and slidable, and slides and descends with respect to the frame as it rotates and tilts with respect to the frame. Scaffolding for scaffolds characterized by
Is preferable.

  If the skirting board main body is simply pivotable on the vertical beam of the frame and the angle posture of the skirting board main body is variable, the lower the skirting board main body is tilted, the more the lower part of the skirting board body rises, and from the footboard of the scaffolding There is a possibility that the skirting board main body is largely separated upward.

  On the other hand, in the skirting board of the above configuration, the skirting board main body is rotatably and slidably supported on the vertical bars of the frame body. The skirting board slides down. Therefore, it is possible to realize a skirting board in which the skirting board main body is difficult to be separated upward from the footboard of the scaffold even when the skirting board main body is largely inclined.

  In addition, various structures can be adopted as a structure that supports the skirting board main body so as to be rotatable and slidable with respect to the vertical crosspiece of the frame body. For example, a support shaft is provided on the vertical crosspiece, and the baseboard main body is provided. A structure in which a long shaft is provided and a support shaft of the vertical beam is inserted into the long hole, or conversely, a support shaft is provided in the base plate body, and a long hole is provided in the vertical beam. The structure etc. which let the support shaft penetrate can be illustrated.

In the means described above,
“The connecting member is in contact with the base plate body inclined at an inclination angle equal to or larger than the inclination angle in a state in which the intermediate tilt holding locking portion is locked to the locking pin, and the width of the connection member with respect to the frame body A contact portion that prevents further rotation of the connecting member that rotates relative to the baseboard body as the tree body tilts is provided,
The intermediate inclination holding locking portion and the maximum inclination holding locking portion are recessed in the upper part of the long hole, respectively, and the locking pin is fitted above the long hole. Scaffolding for scaffolding "
Is preferable.

  If the baseboard body is supported so as to be rotatable and slidable with respect to the vertical beam of the frame, the baseboard body in an inclined state is allowed to be lifted upward within the range in which it can slide. Is done.

  Therefore, as described above, the width is greater than the inclination angle (angle formed by the vertical beam of the frame body and the baseboard body) in the intermediate inclination state in which the intermediate inclination holding engagement portion is engaged with the engagement pin. If the abutment part that abuts against the baseboard body when the wood body tilts and prevents further rotation of the connecting member that rotates with respect to the baseboard body is provided, the width of the intermediate slope state and the maximum slope state The connecting member can be moved upward by lifting the wood body. And if each of the latching part for inclination holding in the middle and the latching part for maximum inclination holding is recessed at the upper part of the long hole and fits the locking pin above the long hole, By lifting and moving the connecting member upward, the locking of the intermediate tilt holding locking portion or the maximum tilt holding locking portion by the locking pin can be released.

  Therefore, according to the skirting board of the above configuration, the locking of the maximum inclination holding locking part or the middle inclination holding locking part by the locking pin can be released by a simple operation such as lifting the base board body. It is possible to change the angular posture of the skirting board body more easily.

  As described above, according to the present invention, it is possible to provide a skirting board that can be attached to a scaffolding pillar without a safety handrail and that can easily change the angular posture of the skirting board main body.

It is a front view which shows an example of the baseboard which concerns on this invention. It is the A section enlarged view of FIG. It is BB sectional drawing of FIG. It is a figure which shows the halfway inclination state of the baseboard main body shown in FIG. It is a figure which shows the maximum inclination state of the baseboard main body shown in FIG.

  Hereinafter, an example as an embodiment of a baseboard for scaffolds according to the present invention will be described in detail with reference to the drawings.

  1-3, an example of the baseboard 100 for scaffolds which concerns on this invention is shown. In addition, in this example, many standing in the length direction of the scaffold extending along the wall surface of the building at a predetermined interval and arranged in parallel in the depth direction of the scaffold (the width direction of the tread 5). The main structure is a support 1, a horizontal member 3 laid between the support pillars 1 in the depth direction of the scaffold, and a tread 5 extended between the horizontal members 3. The wedges 4 of the horizontal member 3 are fitted into the pockets 2 provided in the above, and the column 1, the horizontal member 3 and the step plate 5 are assembled by hooking the hook 6 of the step plate 5 to the horizontal member 3. In the “tightening type scaffold”, an example in which the present invention is applied as a baseboard 100 erected along the side edge portion of the step board 5 is shown, but the baseboard of the present invention is not limited to the wedge-type scaffolding, but a portal type. It can be applied as a baseboard for other types of scaffolds, such as a frame scaffold using a building frame.

  The skirting board 100 includes a frame 10 having a pair of left and right vertical bars 11a and 11b and horizontal bars 12a and 12b provided between the vertical bars 11a and 11b, and the vertical bars 11a and 11b of the frame 10. And a baseboard body 20 that is rotatably supported by the vertical rails 11a and 11b. By rotating the baseboard body 20, the angular posture of the baseboard body 20 with respect to the frame body 10 is increased. It is configured to be variable.

  In this example, as the horizontal rails 12a and 12b constituting the frame body 10, a pair of upper and lower horizontal rail frames 12a of the horizontal rail 12a disposed at the upper portion of the frame body 10 and the horizontal rail 12b disposed at the lower portion thereof. , 12b, but one of the upper and lower horizontal rails 12a, 12b may be omitted.

  The left and right vertical bars 11a and 11b of the frame body 10 are provided with a fixture 15 fixed to the support column 1 of the scaffold, so that the baseboard 100 can be directly attached to the support column 1 of the scaffold. . Specifically, the fixing tool 15 is formed in a wedge shape, and is fixed to the column 1 by being fitted into the pocket 2 of the column 1. Here, by appropriately setting the specific structure of the fixture 15, it is possible to realize a baseboard that can be attached to another type of scaffold such as a frame scaffold.

  The upper part of the skirting board main body 20 is supported not only by the vertical bars 11a and 11b of the frame 10 so as to be rotatable, but also by being slidable. Specifically, a long hole 21 is provided in a side surface of the baseboard body 20, and a support shaft 13 protruding from the vertical bars 11 a and 11 b is rotatable in the long hole 21 and the long hole 21 is elongated. It is slidably inserted in the direction. Therefore, when the skirting board main body 20 is rotated and tilted with respect to the frame body 10, the skirting board main body 20 descends with respect to the frame body 10 as the tilting is greatly performed (see FIGS. 4 and 5). Accordingly, it is possible to prevent a problem that the lower end of the skirting board main body 20 is largely separated upward from the tread board 5 by tilting the skirting board main body 20 greatly with respect to the frame body 10.

  Further, the lower part of the skirting board main body 20 is connected to the vertical bars 11 a and 11 b of the frame body 10 via a connecting member 30. Specifically, one end side of the connecting member 30 is rotatably connected to the lower portion of the skirting board main body 20 via the connecting pin 40, and the other end side of the connecting member 30 is the vertical rails 11 a and 11 b of the frame body 10. It is slidably connected to the vertical bars 11a and 11b via a locking pin 14 provided in the frame. More specifically, the connecting member 30 is provided with a long hole 33, and the locking pin 14 of the vertical rails 11 a and 11 b is inserted into the long hole 33 so as to be slidable in the longitudinal direction of the long hole 33.

  The baseboard body 20 is formed by stretching a face material on a frame-like frame, and in this example, an expanded metal is adopted as the face material. A resin plate or the like can be used as the face material.

  By the way, the skirting board main body 20 is provided with an upright holding locking portion 22 in the lower part on the back side (the side facing the outside of the scaffold). As shown in FIG. 3, the baseboard body 30 is held upright with respect to the frame body 10 by engaging the locking pins 14 of the vertical bars 11 a and 11 b with the upright holding locking portions 22. The In particular, in this example, the upright holding locking portion 22 is bent upward, and the locking pin 14 is positioned above the upright holding locking portion 22 so that the baseboard body 20 is enlarged. As long as the lock pin 14 is not moved upward, the lock of the upright holding lock 22 by the lock pin 14 is not released, and the upright baseboard body 20 can be stably held.

  Further, the elongated hole 33 of the connecting member 30 is provided with a locking portion 33a for maximum inclination holding at one terminal portion (the upper terminal portion in FIG. 3), and is held at an intermediate position at a portion between both ends. A locking portion 33b is provided.

  As shown in FIG. 4, in the middle of tilting the skirting board main body 20 to the maximum, the latching portion 33b for holding the middle slope is latched to the latching pin 14 of the vertical rails 11a, 11b, and the tread 5 is By placing the lower end of the skirting board main body 20, the skirting board main body 20 can be held in a posture with an inclination angle in the middle. Then, as shown in FIG. 5, in the state where the baseboard body 20 is inclined to the maximum, the maximum inclination holding locking portion 33a is locked to the locking pin 14 of the vertical rails 11a, 11b. The skirting board main body 20 can be held in a posture with the maximum inclination angle.

  In this example, as shown in FIGS. 4 and 5, the maximum inclination holding locking portion 33 a and the midway inclination holding locking portion 33 b are connected to the connecting member 30 in a state where the baseboard body 20 is inclined as shown in FIGS. 4 and 5. As long as the connecting member 30 is not moved greatly upward, the maximum tilt holding locking portion 33a and the middle tilt holding locking portion 33b by the locking pin 14 are provided. The lock is not released and the baseboard body 20 in the inclined state can be stably held.

  The connecting member 30 includes a projecting piece 32 that is bent on one side (side toward the outside of the scaffold) of a flat plate-like main body plate 31 provided with a long hole 33. As shown in FIG. 4, the inclination angle of the intermediate inclination state in which the intermediate inclination holding engagement portion 33b is engaged with the engagement pin 14 (with the vertical bars 11a and 11b of the frame body 10 and the baseboard body 20). If the baseboard body 20 is tilted more than the angle, the contact portion that contacts the baseboard body 20 is configured. The function of the contact portion formed by the projecting pieces 32 will be described below.

  As shown in FIGS. 4 and 5, the baseboard 20 in the inclined state is supported by the vertical bars 11 a and 11 b of the frame body 10 so as to be slidable. It can be moved upward.

  On the other hand, when the baseboard body 20 is at least between the intermediately inclined state shown in FIG. 4 and the maximum inclined state shown in FIG. The lower end of the baseboard body 20 abuts the end of the projecting piece 32 on the baseboard body 20 side, and further rotation of the connecting member 30 with respect to the baseboard body 20 is prevented.

  Therefore, if the skirting board main body 20 is lifted in a state where the projecting pieces 32 of the connecting portion 30 are in contact with the skirting board main body 20, the connecting member 30 does not rotate with respect to the skirting board main body 20. At the same time, the connecting member 30 is lifted upward. Each of the maximum inclination holding locking portion 33 a and the midway inclination holding locking portion 33 b provided in the long hole 33 of the connecting member 30 is recessed in the upper portion of the long hole 33. When the connecting member 30 is lifted upward, the locking pin inserted into the maximum tilt holding locking portion 33a or the middle tilt holding locking portion 33b is inserted. 14 is disengaged into the long hole 33 and the locking by the locking pin 14 is released.

  Accordingly, when it is desired to change the inclination angle of the skirting board main body 20 in the middle inclined state as shown in FIG. 4 or to return the upright state to the skirting board main body 20 in the maximum inclined state as shown in FIG. The skirting board main body 20 may be rotated in the upright direction or the maximum inclination direction by lifting the 20 and releasing the locking by the locking pin 14, and the inclination angle of the skirting board main body 20 is changed by a simple operation. be able to.
