Description

  The present invention relates to a scaffolding handrail structure, and is particularly suitable for use in forming a scaffolding handrail including handrail bars and baseboards on a work scaffold composed of a single tube scaffold formed by combining long and short single tubes vertically and horizontally. The present invention relates to the improvement of the scaffolding rail structure.

  Traditionally, when building structures, etc., work scaffolds are provided as temporary structures for workers, and work scaffolds tend to be formed with frame scaffolds in recent years. In view of the superiority of the storage state, it is sometimes formed with a conventional single-tube scaffold.

  The framed scaffolds are arranged at equal intervals so that the framed frames formed in a portal form are orthogonal to the wall of the structure, and the parallel building frames are connected by a standardized scaffolding plate as a horizontal member. At the same time, in order to prevent the side-by-side building frames from collapsing, the brace of a fixed shape is connected to a scaffolding column that is a vertical column that forms the building frame, so that it is assembled in the lateral direction.

  In the case of framed scaffolds, each building frame is connected to each building frame and extended upward, and a scaffolding plate is installed between the building frames extended above, and the building frame extended upwards. Combining comrades with a bracelet, so-called assembling upwards to form a working scaffold.

  On the other hand, a single-tube scaffold is a work scaffold formed by assembling long and short single tubes vertically and horizontally using a clamp that is a dedicated connector, and the long scaffold pillars, which are longitudinal members, are placed on the wall of the structure. The front and rear scaffolding struts are arranged side by side in parallel at an arbitrary interval, and the front and rear scaffolding struts are connected by a short horizontal member as a connecting member, and the laterally aligned scaffolding struts are They are assembled vertically and horizontally by connecting with a long horizontal material that is a directional material.

  When assembling the single pipe scaffold, the long horizontal member is placed and connected to the horizontal member, and a scaffold plate is bridged over the horizontal member, and this scaffold plate is called, for example, a wire. It is bound to a horizontal member with soft iron wire to form a work place where workers can enter.

  In the work scaffold formed as described above, whether it is a frame scaffold or a single pipe scaffold, the scaffold plate may be used as a place for entry of the worker who is a user and a passage, As a measure to ensure the safety of workers, handrails that are traditional handrails have been provided, but in recent years, materials, tools, etc., have been prevented from falling from the work platform, that is, from the scaffolding board. A baseboard is provided.

  Therefore, for example, in the proposal disclosed in Patent Document 1, since the handrail bar and the baseboard enable the length adjustment, the work scaffolding is composed of a frame scaffold formed by a shaped member, Regardless of whether it consists of a single tube scaffold formed of a single tube of any length dimension, it is possible to form a scaffold rail with a handrail bar and a baseboard to the work scaffold, that is, to realize a scaffold rail structure .

Japanese Utility Model Publication No. 3-082663

  However, in the case of the proposal disclosed in Patent Document 1, labor is required for the work when realizing the structure of the scaffolding handrail to the working scaffold, in other words, when forming the scaffolding handrail including the handrail rail and the baseboard to the working scaffold. In addition, there is a problem that the scaffold strut, which is a component of the work scaffold, needs to be modified.

  That is, in the proposal disclosed in Patent Document 1, handrail bars and baseboards are separately formed, and the handrail bars and baseboards that are separately formed are connected to a scaffold column that forms a work scaffold by appropriate connection means. Thus, a scaffolding handrail including a handrail bar and a baseboard is formed on the work scaffold.

  Therefore, according to the proposal of the above-mentioned literature disclosure, when forming a scaffolding handrail with handrail bars and baseboards in the work scaffold, the work of connecting the handrail bars and baseboards to the scaffolding pillars that respectively form the work scaffolding Therefore, there is a problem that labor is required for the work of forming the scaffolding handrail on the work scaffold.

  Further, in the above proposal, the connection of the handrail bar and the baseboard to the work scaffold is based on the connection means, but the structure of this connection means is not limited to the handrail crossbar and the baseboard but also to the scaffolding pillar that forms the work scaffold. Since it is provided, there is a problem that the work scaffolding needs to be modified in forming the scaffolding handrails including handrail bars and baseboards in the work scaffolding.

  The present invention was devised in view of the above-mentioned circumstances, and the purpose of the present invention is that it does not require modification to the work platform, and does not require labor and labor. It is to provide a scaffolding handrail structure that is optimal for forming a scaffolding handrail having a handrail bar and a baseboard on the scaffolding.

  In order to achieve the above-described object, the structure of the scaffolding handrail structure according to the present invention is a scaffolding handrail structure in which a scaffolding handrail having a handrail bar and a baseboard is formed on the working scaffold. A pair of left and right scaffolding struts, and the scaffolding handrail is positioned and standing between the left and right scaffolding struts and is paired on the left and right A left handrail post that is adjacent along the foothold post, a right handrail post that is adjacent along the right foothold post, and a handrail crossing over the upper ends of the right handrail post and the left handrail post The left handrail post is formed in a frame shape integrally including a baseboard connected to each lower end portion of the right handrail post, and the left handrail post is formed on the upper end portion adjacent to the handrail bar. Grip the left scaffolding strut One connecting means or other connecting means, and an engaging portion for allowing the left scaffolding strut to be present inside at a lower end portion adjacent to the baseboard, wherein the handrail is opposed to the right scaffolding strut The right handrail strut is engaged at the lower end adjacent to the baseboard so that the right scaffold strut is present on the inner side, with one connecting means or other connecting means for gripping the right scaffold strut at the right end. And the engaging portion engages the left scaffolding strut and the right scaffolding strut with the left scaffolding strut and the right scaffolding strut facing inside, and the one connecting means or another Assume that the scaffolding handrail is formed on the working scaffold when the connecting means grips the left scaffolding strut and the right scaffolding strut.

  Preferably, the handrail bar is connected to the left handrail post and the right handrail post by welding, and the baseboard is connected to the left handrail post and the right handrail post using a bolt nut, One connecting means or the other connecting means is connected to the left handrail post or the handrail bar by welding, or is swingably or pivotally connected, and the engaging portion is the left handrail post and the handrail. It is assumed that the right handrail post is connected by welding.

  Preferably, the one connecting means is formed in a laterally U-shape in a plan view, and the receiving portion through which the left scaffold strut or the right scaffold strut is inserted is inserted into the receiving portion. And when the receiving part receives the left scaffold strut or the right scaffold strut, the wedge is fitted into the receiving part, and the one connecting means is the left scaffold strut or Assume that the right scaffolding column is gripped.

  Further, preferably, the other connecting means is formed in a lateral C shape in a plan view, and a receiving portion for allowing the left scaffolding strut or the right scaffolding strut to be present on the inside, and pivotally attached to the receiving portion. A pushing part and a stopper pivotally attached to the receiving part, and when the receiving part receives the left scaffolding strut or the right scaffolding pillar, the pushing part is the left scaffolding pillar or the right scaffolding pillar. And the stopper is connected to the pushing portion, and the other connecting means grasps the left scaffold strut or the right scaffold strut.

  Preferably, the working scaffold comprises a single pipe scaffold for connecting long and short single pipes with a clamp, and the single pipe scaffold comprises the left scaffolding strut and the right scaffolding strut comprising a long longitudinal member. At the same time, it is assumed that a scaffolding plate that allows an operator to enter is bridged over the horizontal member connected to the vertical member by the clamp.

  Therefore, according to the scaffolding handrail structure of the present invention, since the scaffolding handrail is formed on the work scaffolding, the scaffolding handrail is formed in a frame shape integrally including a handrail bar and a baseboard. Compared to the case where the handrail bars and baseboards are separately formed and also formed separately from the handrail support pillar or the scaffold support pillar, the work for forming the scaffolding handrail on the work scaffold is time-consuming. It can be done quickly.

  And, according to the scaffolding handrail structure of the present invention, the handrail strut that connects the handrail bar and the baseboard in the scaffolding handrail, and the handrail bar in the scaffolding handrail forms a working scaffold by one connection means or other connection means. Connected to the left and right scaffolding struts.

  At this time, the one connecting means is formed in a wedge structure, so that the handrail pillar is connected to the left scaffolding pillar by the insertion of the wedge, and the handrail bar is connected to the right scaffolding pillar. It is formed on the handrail side and not on the work platform side.

  In addition, the other connecting means is formed in a clamp structure, so that the handrail column is connected to the left scaffolding column, and the handrail bar is connected to the right scaffolding column. It is not formed on the work scaffold side.

  As a result, according to the scaffolding handrail structure of the present invention, when the scaffolding handrail is formed on the work scaffold, the work of forming the scaffolding handrail on the working scaffold can be easily and quickly practiced, and the working scaffold side needs to be modified. Will not.

  When the scaffolding handrail is configured to allow adjustment of the length in the lateral direction, whether the work scaffold is composed of a frame scaffold formed of a shaped member, or an arbitrary length Even in the case of a single-pipe scaffolding formed of a single-pipe size, it is possible to form a scaffolding handrail having handrail bars and baseboards to the work scaffold.

  The present invention will be described below on the basis of the illustrated embodiment. The scaffolding handrail structure of the present invention is not limited to the case of forming a scaffolding handrail having handrail bars and baseboards in a framed scaffolding. It is suitable for forming, that is, embodying a scaffolding handrail including a handrail bar and a baseboard on a work scaffold composed of a pipe scaffold.

  Therefore, in the following illustration and description, it is assumed that the work scaffold is composed of a single pipe scaffold. However, as shown in FIGS. 1 and 2, the single pipe scaffold is composed of long and short single pipes to form a work scaffold S. In general, a single tube that is long and short in an arbitrary size is assembled vertically and horizontally using a clamp C that is a dedicated connector.

  To explain a little, in the case of a single tube scaffold, a long scaffold pillar P, which is a longitudinal member, is paralleled in a lateral direction at an arbitrary interval while being paired in series toward a wall surface of a structure not shown. The scaffold struts P to be connected are connected by a short horizontal member B as a connecting member, and the scaffold struts P aligned in the horizontal direction are connected by a long horizontal member H as a horizontal member to be assembled vertically and horizontally.

  In the case of a single pipe scaffold, a scaffold plate (not shown) is bridged on a horizontal member B parallel in the horizontal direction, and this scaffold plate is also not shown, but for example, soft iron called a wire It is bound to the horizontal member B with a wire to form a place for workers to enter.

  Incidentally, in the following description, for ease of understanding, for the scaffold strut P forming the work scaffold S composed of a single tube scaffold, the scaffold strut P on the left and right in the front row in FIG. In FIG. 2, the left and right scaffolding pillars P are a left scaffolding pillar P1 and a right scaffolding pillar P2, respectively.

  On the other hand, the frame scaffolding is not shown in the figure, but the fixed building frames formed in a gate shape are arranged at equal intervals so as to be orthogonal to the wall surface of the structure, and the parallel building frames form a horizontal member In order to prevent the collapse of the parallel building frames, the fixed braces are connected to the scaffolding struts, which are parallel vertical struts, so as to prevent the collapse of the parallel building frames.

  In the case of framed scaffolds, each building frame is connected to each building frame and extended upward, and a scaffolding plate is installed between the building frames extended above, and the building frame extended upwards. Combining comrades with a bracelet, so-called assembling upwards to form a working scaffold.

  By the way, the scaffolding handrail structure of the present invention is suitable for use in forming the scaffolding handrail F including handrail bars and baseboards on the working scaffold S composed of a single tube scaffold as well as the working scaffold composed of a frame scaffold. There are the following reasons.

  As is well known, framed scaffolds form work scaffolds by connecting the stylized components, but they form a building frame as a component and form vertical frames between the left and right columns, that is, between the scaffold columns. As for the provision, for example, as disclosed in Japanese Patent Application Laid-Open No. 2010-196403, there are many proposals for a leading handrail.

  This leading handrail is based on the idea of providing a handrail bar on the upper stage before the upper stage is continuously formed when the lowermost stage of the work scaffold consisting of the framework scaffold is completed. While called an “advanced” handrail, it is formed so that it is possible to provide a handrail bar on the upper portion of the work scaffold with a simple operation even if the upper foot, ie, the scaffold is not formed.

  This is due to the fact that the frame scaffold itself is formed of formed components. In this regard, a single-tube scaffold is formed of a single tube that is long and short in an arbitrary size. In addition, the handrail bar is often formed on the assembled work scaffold S in a “retrofitting” posture using, for example, a single tube and a clamp. In fact, no proposal has been made to enable a handrail to be provided on the work platform S and a baseboard in a simple work.

  Therefore, the applicant of the present application makes it possible to provide a handrail with a simple work like the above-mentioned preceding handrail on the work scaffold S composed of the assembled single pipe scaffold, It is a proposal to make it possible.

  Based on the above assumptions, the scaffolding handrail will be described. As shown in FIGS. 1 and 2, the scaffolding handrail F is located on the working scaffold S, and the left and right scaffolding columns P facing outward, that is, in front view. Thus, a pair of left and right scaffolding struts P1 and P2 that are aligned in parallel in the left-right direction is positioned and erected.

  Incidentally, the standing state of the scaffolding handrail F is not shown, but it is the same even in the framed scaffolding. Therefore, as will be described later, the scaffolding handrail F is used as the left scaffolding column P1 and the right scaffolding column P2. The same applies to the positioning procedure between the two.

  The scaffolding handrail F is located in the work scaffold S, and is positioned between the left scaffolding strut P1 and the right scaffolding strut P2, and is erected on the left scaffolding strut P1 and the right scaffolding strut P2. It is assumed that at least the upper end of the scaffolding handrail F and further the lower end of the scaffolding handrail F are moved into and out of the work scaffold S, that is, swinging is prevented.

  Therefore, in the present invention, the scaffolding handrail F is a pair of left and right handrail struts 1 adjacent along the left scaffolding strut P1 and the right handrail strut 2 adjacent along the right scaffolding strut P2, A handrail bar 3 spanning the upper ends of the left handrail post P1 and the right handrail post P2 and a baseboard 4 connected to the lower ends of the left handrail post P1 and the right handrail post 2 are integrally formed. It is assumed that the frame is formed.

  In the present invention, the scaffolding handrail F includes an engaging portion that engages with the left handrail post P1 and the right handrail post P2 on the lower side, and the left handrail post P1 and the right handrail post on the upper side. It is assumed that one connecting means 6 for gripping P2 or another connecting means 8 is provided.

  By the way, the scaffolding handrail F according to the present invention includes an intermediate rail 5 parallel to the handrail rail 3 and the baseboard 4 between the railing rail 3 and the baseboard 4. It is provided based on the fact that it is stipulated in the related laws and regulations concerning the handrail device.

  As described above, in the present invention, the scaffolding handrail F is formed in the frame shape, so that the scaffolding handrail F is formed on the work scaffold S. In the scaffolding handrail F, the handrail bar 3 and the baseboard 4 are separately formed, and the handrail post, that is, the left handrail post 1 and the right handrail post 2 are formed separately. Compared to the case where it is made, or compared to the case where it is formed separately from the scaffolding column P, that is, the left side scaffolding column P1 and the right side scaffolding column P2, as proposed in the above-mentioned Patent Document 1. Thus, the work of forming the scaffolding handrail F on the work scaffold S can be easily and quickly performed without requiring labor.

  Further, the scaffolding handrail F is integrally formed in a frame shape, so that it is advantageous in that the number of parts can be reduced and the area for storage and storage when not in use can be made large. .

  Returning, the scaffolding handrail F according to the present invention may be formed of any material as long as it has a predetermined configuration, but most of this kind of scaffolding handrail is conveyed by the operator, that is, by the hand. Considering that there are many opportunities, it is preferable that the aluminum alloy be formed as light as possible, for example, by selecting an aluminum alloy as a material.

  By the way, in the scaffolding handrail F according to the present invention, the left handrail support column 1, the right handrail support column 2, the handrail beam 3 and the middle beam 5, which are constituent members, are pipe materials whose diameter is smaller than that of the scaffolding column P. In particular, it is composed of a square pipe. This is for reducing the total weight of the scaffolding handrail F formed in a frame shape as much as possible, and for the handrail bar 3 for the left handrail column 1 and the right handrail column 2. And the connection of the middle rail 5 to the left handrail support column 1 and the right handrail support column 2 by using bolts and nuts are easier than in the case of a round pipe, and when not in use. This is a setting from the standpoint that stacking and storage can be easily performed compared to the case of using round pipes. Therefore, the left handrail post 1, the right handrail post 2, and the handrail Pier 3 and inside 5 does not exclude that it is formed by a round pipe it is a matter of course.

  The left handrail support column 1 and the right handrail support column 2 are made of a pipe material as shown in the figure, but the left handrail support column 1 and the right handrail support column 2 are the handrail beam 3 and the baseboard 4 and further the middle beam 5. If the frame-shaped body is formed by integrally connecting the two, the pipe may be made of an angle material or other shape material as long as it has a predetermined mechanical strength. Of course.

  From the viewpoint of ensuring personal safety such as preventing the operator from falling from the work scaffold S, the handrail bar 3 is formed by selecting an arbitrary member as long as it has a predetermined mechanical strength. good.

  However, in the case of the handrail 3, in view of the fact that the worker's body is often touched or touched by the hand, a member that does not feel uncomfortable or uncomfortable as much as possible is selected. From that point of view, it will preferably be a square pipe.

  When the handrail bar 3 is a square pipe, the left handrail post 1 and the right handrail post 2 are each a square pipe, and when the handrail bar 3 or both are round pipes, In comparison, it is advantageous in that the welding operation can be facilitated.

  The skirting board 4 is provided below the middle rail 5 arranged below the handrail rail 3, so that materials and tools that may be placed on a scaffolding board (not shown) are provided to the operator. Jumping out of the work platform S by being kicked by mistake is prevented in advance.

  From the viewpoint of preventing materials and tools that are kicked by an operator from jumping out of the work scaffold S, the baseboard 4 is formed of an arbitrary member as long as it has a desired so-called height. However, in other words, it is preferable to select and form a member that is not easily deformed even if it is accidentally kicked by an operator.

  From the above, as the baseboard 4, for example, a plate material is preferably selected. However, in the baseboard 4 formed on the work scaffold S, an operator may put his foot on the upper end. Also, from the viewpoint that it is necessary to provide a predetermined strength against external force such as impact, it is preferable that the upper and lower end portions be bent portions 4a and 4b so as to be in a so-called reinforcing state.

  When the baseboard 4 is connected to the left handrail support column 1 and the right handrail support column 2 and is temporarily deformed or the like due to the use of the bolt nut 41 (see FIGS. 2 and 3). Care is taken to make that exchange possible.

  As described above, the intermediate rail 5 is provided in accordance with the provisions of related laws and regulations, but in view of being an auxiliary member that ensures the mechanical strength of the handrail rail 3, it cannot be formed more simply than necessary.

  Therefore, in the illustrated embodiment, it is formed so as to have a mechanical strength substantially equivalent to that of the upper handrail bar 3 and is integrally connected to the left handrail post 1 and the right handrail post 2. It is supposed to.

  On the other hand, in consideration of the actual use of the scaffolding handrail F, it is well known that the middle rail 5 is easily deformed, such as being bent, compared to the handrail rail 3, and in view of this easy deformation, the illustrated embodiment is shown. In the embodiment, by using the mounting plate 51 (see FIGS. 2 and 5) and the bolt nut 52 (see FIGS. 2 and 5), the left handrail column 1 and the right handrail column 2 are detachably coupled. It is said.

  Returning, the scaffolding handrail F according to the present invention is provided with a connecting means 6 for gripping the left scaffolding column P1 at the upper end of the left handrail post 1 adjacent to the handrail bar 3 and the lower end adjacent to the baseboard 4. The left scaffolding strut P1 is made to be present on the inside, that is, the engaging part 7 is engaged with the left scaffold strut P1.

  Further, in this scaffolding handrail F, the handrail bar 3 is provided with one connecting means 6 for gripping the right scaffolding pillar P2 at the right end facing the rightward scaffolding pillar P2, and the right handrail pillar P2 is the baseboard 4 It is assumed that the right scaffolding strut P2 is adjacent to the inside at the lower end adjacent to the inner side, that is, the engaging part 7 is engaged with the right scaffolding strut P2.

  As a result, the one connecting means 6 connects, or forms, the work handrail F to the work scaffold S without requiring any modification to the work scaffold S. As long as it is possible, it may be formed arbitrarily.

  Therefore, in the embodiment shown in FIG. 1 and FIG. 2, the one connecting means 6 is formed in a laterally U-shape in plan view, as shown in FIG. A receiving portion 61 for inserting the P1 or right scaffolding column P2, a wedge 62 fitted into the receiving portion 61, and a connecting portion 63 for connecting the receiving portion 61 to the handrail post 1 or the handrail 3; When 62 is inserted into the receiving part 61, one connecting means 6 is supposed to hold the left scaffolding column P1 or the right scaffolding column P2.

  Therefore, in the case of the one connecting means 6 having the so-called wedge structure, when the receiving portion 61 is in a position to insert the left scaffolding column P1 and the right scaffolding column P2, the receiving unit 61 When the wedge 62 is inserted, that is, by the operation of inserting the wedge 62 into the receiving portion 61, the upper end side of the scaffolding handrail F is connected to the work scaffold S, and the scaffolding including the handrail bar 3 and the baseboard 4 is provided. The handrail F can be formed on the work scaffold S in a stationary state.

  In addition, said connection part 63 forms the space of arbitrary dimensions between the scaffold support | pillar P1, P2 and the handrail support | pillar 1 and 2, and this operator forms a handrail support | pillar by forming this space. 1 and 2, the scaffolding handrail F is positioned between the left scaffolding strut P1 and the right scaffolding strut P2, or the scaffolding handrail F is positioned between the left scaffolding strut P1 and the right scaffolding strut P2. It will enable smooth practice of the removal work.

  As shown in FIG. 5, the engaging portion 7 is formed in a laterally U-shape in plan view with respect to the one connecting means 6 formed as described above, and the left scaffolding column P <b> 1 or the right side is formed on the inner side. A bracket 71 on which the scaffolding column P2 is present is provided.

  A connecting portion 72 is welded to the bracket 71, and the connecting portion 72 is connected to the lower ends of the left handrail post 1 and the right handrail post 2 by welding.

  Therefore, in this engagement portion 7, the lower end side of the scaffolding handrail F is connected to the work scaffold S when the bracket 71 is in a posture to allow the left scaffolding strut P1 and the right scaffolding strut P2 to be present inside. Thus, the scaffolding handrail F including the handrail bar 3 and the baseboard 4 can be formed in a state of being stationary on the work scaffold S.

  The connecting portion 72 forms a space of an arbitrary size between the scaffolding struts P1 and P2 and the handrail struts 1 and 2 in the same manner as the connecting portion 63 in the one connecting means 6 described above. Grips the handrail pillars 1 and 2 and positions the scaffolding handrail F between the left scaffolding pillar P1 and the right scaffolding pillar P2, or the scaffolding handrail F with the left scaffolding pillar P1 and the right scaffolding pillar P2. It is said that this space will be useful for the work to remove from between.

  By the way, when the scaffolding handrail F is connected to the left scaffolding column P1 and the right scaffolding column P2 in the work platform S, that is, when the scaffolding railing F is positioned between the left scaffolding column P1 and the right scaffolding column P2. The one connecting means 6 and the locking portion 7 do not hinder the operation, that is, the one connecting means 6 and the locking portion 7 should not interfere with the left scaffolding pillar P1 and the right scaffolding pillar P2. Is vital.

  On the other hand, in the assembled work scaffold S, the distance between the left scaffold strut P1 and the right scaffold strut P2 is the same regardless of whether the work scaffold S is a frame scaffold or a single tube scaffold. Therefore, in the scaffolding handrail F which is erected between the left scaffolding column P1 and the right scaffolding column P2, the one connecting means 6 and the engaging portion 7 are connected to the railing rail 3 or the baseboard. In the case of projecting in the axial direction that is the distribution direction of 4, it is impossible to stand between the left scaffolding pillar P1 and the right scaffolding pillar P2 in this state.

  Therefore, in the present invention, the scaffolding handrail F can be expanded and contracted in the axial direction, which is the direction in which the handrail bars 3 and the baseboards 4 are arranged, and stands between the left scaffolding pillar P1 and the right scaffolding pillar P2. When it is connected to the left scaffolding column P1 and the right scaffolding column P2, it is possible to return to the standard scale, in other words, in the scaffolding handrail F of the present invention, Consideration is given so that it can be formed not only on a work scaffold S made of a single pipe scaffold but also on a work scaffold S made of a frame scaffold.

  Therefore, first, the handrail bar 3 made of a pipe material is connected to the upper end of the left handrail support column 1 and extends toward the right handrail support column 2 at the base end as shown in FIG. As shown also in FIG. 6, a base 31 is connected to the upper end of the right handrail post 2 and an adjustment part 32 is provided with the tip extending toward the left handrail post 1.

  In the handrail bar 3, the diameter of the adjustment portion 32 is larger than the diameter of the main body portion 31, and the main body portion 31 is inserted into the adjustment portion 32 so as to be able to appear and retract.

  By the way, from the viewpoint that the handrail bar 3 has the main body 31 and the adjustment portion 32 to enable the length adjustment, the adjustment portion 32 is formed with a diameter smaller than that of the main body 31 and is not shown. It goes without saying that the length can be adjusted by inserting the part 32 into the main body part 31 so as to be able to appear and retract.

  Returning to the handrail bar 3, an adjustment state maintaining means 33 is provided between the adjustment portion 32 and the tip of the main body portion 31. The adjustment state maintenance means 33 is connected to the adjustment portion 32. A long hole 32a that extends along the axial direction of the adjustment portion 32 that has been opened, and a bolt nut 33a that is threaded into the distal end portion of the main body portion 31 that is positioned inside the adjustment portion 32 through the long hole 32a. It is equipped with.

  Therefore, according to this adjustment state maintaining means 33, when the bolt nut 33a is loosened, the main body 31 and the adjustment part 32 can be moved relative to each other, and the length of the handrail bar 3 can be adjusted. When the bolt nut 33a is tightened, the length can be fixed in the handrail bar 3.

  As a result, in the scaffolding handrail F of the present invention, this is positioned between the left scaffolding strut P1 and the right scaffolding strut P2 in the working scaffold S, and this is the left scaffolding strut P1 and the right Removal from between the scaffolding strut P2 can be easily and freely realized.

  In addition, although the connection part 63 in the one connection means 6 described above is connected to the adjustment part 32 of the handrail bar 3 without any boundary, it may be connected later by using welding or the like. Of course it is good.

  Next, the baseboard 4 is in the present invention, and as shown in FIG. 5, the baseboard 4 is composed of a plate-like body having upper and lower ends bent portions 4 a and 4 b, and the base end is the lower end of the left handrail post 1. The base part 42 is connected to the lower part of the right handrail post 2 and the base end part is connected to the lower end part of the right handrail post 2 by using the bolt nut 41. And an adjustment portion 43 that extends toward the left handrail post 1 at the tip.

  In the baseboard 4, it is assumed that the height dimension of the adjustment section 43 is lower than the so-called height dimension of the main body section 42, and the adjustment section 43 is inserted into the main body section 42 so as to be able to appear and retract.

  By the way, from the viewpoint that the baseboard 4 has the main body part 42 and the adjusting part 43 to enable the length adjustment, the adjusting part 43 is formed taller than the main body part 42 to adjust the length. It goes without saying that the length adjustment may be made possible by inserting the main body portion 42 into and out of the portion 43 so as to freely appear and retract.

  Further, as shown in FIG. 2, the middle rail 5 made of a pipe material has a base end portion connected to an intermediate portion in the vertical direction of the left handrail post 1 and a tip portion in the vertical direction of the right handrail post 2. The main body 53 extending toward the center and the base end are connected to the vertical intermediate portion of the right handrail post 2 and the distal end extends toward the vertical intermediate portion of the left handrail post 1 And an adjusting unit 54.

  In the middle beam 5, it is assumed that the diameter of the adjustment unit 54 is smaller than the diameter of the main body 53, and the adjustment unit 54 is inserted into the main body 53 so as to be able to protrude and retract. From the standpoint of having the main body 53 and the adjustment portion 54 to enable length adjustment, the adjustment portion 54 is formed to have a diameter larger than that of the main body 53, and the main body 53 is adjusted. Of course, it may be inserted freely.

  Therefore, as described above, in the scaffolding handrail F formed in a frame shape, the handrail bar 3, the baseboard 4 and the middle bar 5 can be expanded and contracted in the axial direction which is the extending direction thereof. When positioning this scaffolding handrail F between the left scaffolding strut P1 and the right scaffolding strut P2 forming the work scaffold S, the so-called lateral total length is reduced so that the left scaffolding strut P1 and the right scaffolding. So-called unreasonable positioning with respect to the support P2 can be performed easily and quickly, and the work scaffold S can be easily and quickly removed from the left scaffolding support P2 and the right support support P2. It can be practiced.

  When the scaffolding handrail F is connected to and released from the left scaffolding strut P1 and the right scaffolding strut P2, only the operation of inserting / removing the wedge 62 into the receiving part 61 is provided in the one coupling means 6. This also makes it easy and quick to practice this.

  FIG. 7 shows a state in which a scaffolding handrail F according to another embodiment of the present invention is formed on a work scaffold S composed of a single tube scaffold. Hereinafter, the scaffolding handrail F of this other embodiment will be described. explain.

  In addition, in the place shown in this FIG. 7, the horizontal member H is connected to the clamp (refer the code | symbol C in FIG. 2) which connects the horizontal member B which forms the work scaffold S to the scaffolding column P, and a horizontal member. The illustration of the clamp (see symbol C in FIG. 2) is omitted.

  In the scaffolding handrail F shown in FIG. 7, it is assumed that the means for connecting the left scaffolding column P1 and the right scaffolding column P2 forming the working scaffold S comprises the other coupling unit 8. It is assumed that an opening A that allows the operator to pass through is formed in the part.

  The other connecting means 8 connects the work handrail F to the work scaffold S without any modification to the work scaffold S as a result, similarly to the one connection means 6 described above. As long as it is possible to do so, it may be formed arbitrarily, but in the illustrated case, it is formed in a clamp structure.

  That is, as shown in FIG. 8, the other connecting means 8 is formed in a horizontal C-shape in a plan view, and a receiving portion 81 for allowing the left scaffold strut P1 or the right scaffold strut P2 to be present inside, A pressing portion 82 pivotally attached to the receiving portion 81 and a stopper 83 pivotally attached to the receiving portion 81 are provided. When the receiving portion 81 receives the left scaffolding column P1 or the right scaffolding column P2, the pushing unit 82 swings. The stopper 83 is connected to the pushing portion 82 and the other connecting means 8 grips the left scaffolding column P1 or the right scaffolding column P2 while contacting the left platform column P1 or the right platform column P2. It is said.

  The left handrail post 1 that connects the handrail bar 3 to the upper end includes an engaging portion 7 at the lower end near the baseboard 4, and the right handrail post 2 has the engaging portion 7 at the lower end. The engaging portions 7 are engaged with the left scaffolding column P1 or the right scaffolding column P2.

  Therefore, in the case of the other connecting means 8 formed in the so-called clamp structure, the stopper 81 when the receiving portion 81 and the pushing portion 82 are in a posture to hold the left scaffolding column P1 and the right scaffolding column P2 is used. The upper end side of the scaffolding handrail F can be connected to the work scaffold S by the tightening operation, and the scaffolding handrail F including the handrail bar 3 and the baseboard 4 can be easily and quickly formed on the work scaffold S in a stationary state. It becomes possible.

  By the way, even in the scaffolding handrail F of this other embodiment, the handrail bar 3 and the baseboard 4 can adjust the length in the axial direction as the distribution direction of the handrail crosspiece 3 and the baseboard 4, The length of the middle rail 5 is not allowed to be adjusted.

  This is based on the fact that the scaffolding handrail F partially forms an opening A that allows the operator to pass through, and this opening A is adjacent to the right scaffolding column P2 in the illustration. It is supposed to be provided at the site.

  For this reason, the scaffolding handrail F includes an auxiliary handrail post 9 parallel to the left handrail post 1 and the right handrail post 2 between the left handrail post 1 and the right handrail post 2. The column 9 has an upper end connected to the handrail bar 3 and a lower end connected to the baseboard 4, and an intermediate rail 5 parallel to the handrail bar 3 and the baseboard 4 is interposed between the auxiliary handrail post 9 and the left scaffolding column 1. And an opening A is formed between the auxiliary handrail column 9 and the right scaffold column 2.

  Incidentally, the opening A allows the operator to pass through the passage, but if not used as a passage, it is so-called from the viewpoint that the middle rail 5 is required below the handrail rail 3. It is preferably maintained in a closed state.

  In view of this, as shown in FIG. 8, an auxiliary bar 55 that crosses the opening A is provided as shown by a one-dot chain straight line in FIG. 8. As indicated by the circular arc line, it may be formed in a twisted beam structure, and although not shown, it may be held in the middle beam 5 so as to be freely movable.

  Returning, even in this scaffolding handrail F, the handrail bar 3 is formed so as to freely expand and contract. However, a specific form thereof will be described. A main body 31 is connected to the upper end of the balustrade post 1 and has a distal end extending toward the right handrail post 2, and a base end is connected to the upper end of the right handrail post 2 and the distal end is connected to the left handrail. And an adjustment unit 32 extending toward the support column 1.

  In the handrail bar 3, the adjustment portion 32 is placed on the front end portion of the main body portion 31, and the inner side of the guide socket 34 provided at the upper end of the front end portion of the main body portion 31 is inserted. .

  Incidentally, a retaining pin 32b protrudes from the tip of the adjusting portion 32, and the retaining pin 32b interferes with the guide socket 34, so that the adjusting portion 32 comes out of the guide socket 34, that is, The adjustment unit 32 is prevented from being separated from the guide socket 34.

  Next, the baseboard 4 is basically formed of a plate-like body having upper and lower ends bent portions 4a and 4b so as to freely expand and contract following the handrail bar 3, and the base end is A main body portion 42 is connected to the lower end portion of the left handrail post P1 by using a bolt nut 41, and the distal end extends toward the right handrail post P2, and the base end portion is connected to the lower end portion of the right handrail post P2. An adjustment portion 43 that connects and extends the distal end portion toward the left handrail post P1, and the main body portion 42 connects the base end portion to the lower end portion and extends the distal end portion toward the adjustment portion 43. An insertion portion 44 formed in a rod shape is provided, and this insertion portion 44 is inserted into the adjustment portion 43 so as to be able to appear and retract, thereby enabling the length adjustment.

  In other words, the adjusting portion 43 is made of a pipe material, and has a base end connected to the right handrail post 2 and a distal end extending toward the left handrail post 1. Although the insertion portion 44 is inserted into the adjustment portion 43 so as to be able to appear and retract, instead of this, the adjustment portion 43 may be inserted into the insertion portion 44 so as to be freely extended and retractable, although not shown.

  It is to be noted that the baseboard 4 is provided at the portion located in the opening A, and is provided with the insertion portion 44 formed in a rod shape that lowers the height, not the plate shape. This is because the passage is taken out, and consideration is given so as not to obstruct the operator from passing through.

  Therefore, as described above, like the scaffolding handrail F shown in FIG. 2 described above, in the scaffolding handrail F formed in a frame shape, the rails 3 and the baseboard 4 are in the respective extending directions. Since the scaffolding handrail F is positioned between the left scaffolding strut P1 and the right scaffolding strut P2 forming the work scaffold S, the total length in the lateral direction is reduced. The so-called unreasonable positioning between the left scaffold strut P1 and the right scaffold strut P2 can be easily and quickly performed, and the left and right scaffold struts P2 between the left scaffold strut P2 and the right scaffold strut P2 in the work scaffold S. It will be easy to remove from and be able to practice quickly.

  When the scaffolding handrail F is connected to and released from the left scaffolding column P1 and the right scaffolding column P2, in addition to the engagement of the engaging portion 7 to the left scaffolding column P1 and the right scaffolding column P2, Thus, since only the operation of connecting and disconnecting the other connecting means 8 to the left scaffolding column P1 and the right scaffolding column P2 is sufficient, this can be easily and quickly practiced.

  By the way, the scaffolding handrail structure according to the present invention is intended to be used when the scaffolding handrail F is formed on the work scaffolding S composed of a single pipe scaffolding. One connection means 6 provided on the side or another connection means 8 is formed on the work scaffold S by gripping the scaffold column P of the work scaffold S.

  On the other hand, the leading handrail is configured to rise with the lower side connected to a scaffolding column P that forms the lower work scaffold S, and is based on the lower work scaffold S, that is, the lower work scaffold S is When present, it is possible to form a handrail for the upper scaffolding.

  In other words, the scaffolding handrail F of the present invention does not rely on the lower work scaffold S, that is, the lower scaffold support P, in forming the work scaffold S, so the scaffold support P, that is, the work scaffold S is provided on the lower stage. Even if it does not exist, it has a feature that allows its formation.

  In addition, in the scaffolding handrail F of the present invention, when the gripping force of the one connecting means 6 or the other connecting means 8 on the scaffolding column P is reduced, the scaffolding handrail F formed in a frame shape is used as the scaffold. It is expected that it will slide down next to the column P.

  At this time, when the work scaffold S is a single pipe scaffold, the horizontal member C is positioned on the outside and the side of the scaffold support P, and therefore the scaffold handrail between the left scaffold support P1 and the right scaffold support P2. Even if F slides down, in the worst case, the lower end of the scaffolding handrail F is placed on the horizontal member C, and further sliding down is prevented.

  On the other hand, when the work scaffold S is composed of a frame scaffold, there is no scene where the horizontal member C is positioned outside or on the side of the scaffold column P. Therefore, between the left platform column P1 and the right platform column P2. When the scaffolding handrail F slides down, there is no member that prevents this, and means or a configuration for preventing the scaffolding handrail F from sliding down are required.

  From the above, it can be said that the scaffolding handrail F of the present invention has a feature that is suitable for forming a work scaffold S composed of a single pipe scaffold. However, as described above, the scaffolding handrail F of the present invention is based on a framework scaffold. It is not excluded that it is suitable for forming a working scaffold S.

  As described above, one connecting means 6 and the other connecting means 8 are connected to the handrail support column 1 or to the handrail bar 3 in a fixed state by welding. When positioning between the right scaffolding column P2 and the right coupling column P2, the one coupling unit 6 and the other coupling unit 8 are positioned quickly while avoiding any interference with the left platform column P1 or the right platform column P2. In order to make it possible, one connecting means 6 and another connecting means 8 may be held swingably or pivotably on the handrail support column 1.

  Further, in the above-described place, the position of the one connecting means 6 on the left and right or the other connecting means 8 and the position where the engaging portion 7 on the left and right is provided, that is, the height position in the vertical direction, Of course, the left and right scaffolding handrails F are connected to one scaffolding column P so that they do not interfere with each other.

  In the embodiment shown in FIG. 2 described above, another connecting means 8 may be provided in place of the one connecting means 6, and in the embodiment shown in FIG. Of course, instead of the means 8, one connecting means 6 may be provided.

  2 may be provided instead of the handrail bar 3 in the embodiment shown in FIG. 7, and conversely in the embodiment shown in FIG. Of course, instead of this, the handrail bar 3 in the embodiment shown in FIG. 2 may be provided.

  Although the description of the scaffolding handrail structure according to the present invention has been completed above, the above description is an example, and the configuration of the present invention is of course not limited to the above.
