Description

  The present invention relates to a gap closing material capable of closing a gap formed at a non-elevating side end of a staircase opening of a frame scaffold used in a construction site or the like, and a frame scaffold incorporating this gap closing material.

  As for frame scaffolds used in construction sites, for example, “building frame type scaffolds” in which struts or handrail frames are attached to building frames, support members and brace materials (also called diagonal materials), and the like. There is a “tightening type scaffolding” in which scaffolding members such as handrail members are tightly assembled.

  A “building frame-type scaffold” is usually formed by assembling a plurality of H-shaped or torii-shaped building frames composed of horizontal rails and vertical columns. In other words, a plurality of building frames are erected at right angles to a structure such as a building at a predetermined interval, and a plurality of building frames are installed by fixing a streak or a handrail frame between vertical columns of adjacent building frames. After the frame is self-supporting, one or two or more cloth frames with floors (also referred to as cloth plates) are bridged between the horizontal bars of the adjacent building frames to form one unit of scaffolding. Next, a separately prepared building frame was erected on the building frame that had already been erected, and in the same manner, a streak and a handrail frame were attached and fixed between adjacent building frames, and then newly erected. A one-step scaffold is formed by laying one or more cloth frames with a floor on the horizontal rail of the building frame. By repeating this sequentially, the entire framework scaffolding is formed.

  An example of forming a building-frame-type frame scaffold using an H-shaped building frame (hereinafter referred to as “H frame”) as this building frame is shown in FIG. (a) is a front view, (b) is a right side view.

  The three H frames 1 are arranged at equal intervals at right angles to the building 22, and the handrail frame 10 is attached to the lock fitting 6b on the opposite side of the building between the adjacent H frames. Make them independent. Further, the handrail frame 10 is attached to the lock fitting 7b on the side opposite to the building, and the handrail frame 13 on the building side is attached to the lock fitting 7a and fixed. Thereafter, the cloth frame 11 with a floor is bridged between the horizontal rails 3 of the H frame 1 adjacent to the first stage to form a first stage scaffold. Next, the lower part of the vertical column 2 of the H frame 1 separately prepared is placed on the vertical column 2 of the first stage H frame 1 that has already been erected, and fixed with a fixing pin (not shown). Thus, the second stage H frame 1 is erected. Thereafter, in the same manner as the first stage, the handrail frame 10 is attached to the lock fittings 6b and 7b on the side opposite to the building, and the handrail frame 13 is attached and fixed to the lock fitting 7a on the building side. A cloth frame 11 with a floor is bridged on the horizontal rail 3 of the H frame 1 of the eye to form a second stage scaffold. The third stage scaffolding is assembled in the same manner as the second stage scaffolding. That is, the handrail frame 10 is attached to the opposite side of the building, the handrail frame 13 is attached and fixed to the building side, and then the cloth frame 11 with a floor is bridged on the horizontal rail 3 of the third H frame 1. To form a third stage scaffold. In this way, the frame scaffold is formed until the required number of steps is reached.

  As another example of using a building frame, FIG. 2 shows an example in which a building frame-type frame scaffold is formed using a torii-shaped building frame (hereinafter referred to as “torii frame”). (a) is a front view, (b) is a right side view.

  First, three torii frames 4 are arranged at equal intervals at right angles to the building 22, between the adjacent torii frames 4 and a streak 13 is attached to the lock fitting 8b on the opposite side of the building, and also on the building side. The first stage scaffolding is formed by attaching the strut 13 to the lock fitting 8a and allowing the first stage torii frame 4 to stand on its own. Thereafter, a floor-mounted cloth frame 11 serving as a second-stage scaffolding plate is bridged between the horizontal rails 3 at the upper part of the first-stage adjacent torii frame 4, and then the first-stage torii frame 4 already erected. The lower part of the vertical column 2 of the torii frame 4 prepared separately is placed on the vertical column 2 and fixed with a fixing pin (not shown), whereby the second stage torii frame 4 is erected. Thereafter, in the same manner as the first stage, the streak 13 is attached to the lock fitting 8b on the side opposite to the building, and the streak 13 is also attached to the lock fitting 8a on the building side, so that the second stage torii frame 4 The second stage scaffolding is formed by allowing the to stand independently. Thereafter, a floor-mounted cloth frame 11 serving as a third-stage scaffolding plate is bridged between the horizontal rails 3 on the upper side of the second-stage adjacent torii frame 4, and then the second-stage torii frame 4 already erected. The lower part of the vertical column 2 of the torii frame 4 prepared separately is placed on the vertical column 2 and fixed with a fixing pin (not shown), so that the third level torii frame 4 is erected. Thereafter, in the same manner as in the second stage, the streak 13 is attached to the lock fitting 8b on the opposite side of the building, and the strut 13 is also attached to the lock fitting 8a on the building side, and the third stage torii frame 4 A third-stage scaffolding is formed by allowing the to stand independently. In this way, the frame scaffold is formed until the required number of steps is reached.

  On the other hand, a “tightening type scaffold” is a structure in which scaffolding members such as handrail members, brace members, and brace members are attached to support members provided with a plurality of attachment members called “tops” through the tops. After these scaffold constituent members are fastened together with a wedge or the like, they are assembled by suspending one or more floored cloth frames.

  FIG. 3 shows an example of the structure of a tight-binding scaffold. (a) is a front view of a binding type scaffold, (b) is an enlarged view of the periphery of the top indicated by a circle in (a), and (c) is a right side view of the binding type scaffold.

  In the binding type scaffolding, three columns 14 are erected on the building side and on the opposite side. Each column 14 is formed by vertically adding column members 16 having a plurality of tops 20. A brace member 19 is attached between adjacent struts 14 on the building side via a top 20, and a work handrail 15 is interposed between adjacent struts 14 on the opposite side of the building via a top 20. Are attached and fastened with a wedge or the like at the top 20. Further, an arm wood 21 is attached between the building-side column 14 and the column 14 on the opposite side of the building via a frame 20, and is fastened with a wedge or the like at the frame 20. The first-stage scaffolding is formed by bridging the cloth frame 11 with a floor therebetween. The brace material 19 may be attached between the columns 14 on the opposite side of the building.

  The second stage scaffold is formed in the same manner as the first stage scaffold. If necessary, a brace member 19, a handrail member 15, and a brace member 21 are attached and tightened via a frame 20 after a separately prepared strut 14 is vertically added to the upper end of the strut 14 of the first stage scaffold. Then, it is formed by bridging the cloth frame 11 with a floor. By repeating this in sequence, a multi-stage tight scaffold is formed.

  In this way, a frame scaffolding is formed, in which one or two cloth frames with floors are placed between adjacent crosspieces or timbers of adjacent building frames so that workers can move the frame scaffolds horizontally. This is used as a work floor and a passage. That is, it is bridged between the adjacent horizontal rails 3 in the case of a building frame type scaffold, and between the adjacent arm lumbers 21 in the case of a tight type scaffold. At this time, according to the width of the work floor and passage of the frame scaffold, that is, depending on the length of the horizontal rail of the building frame or the length of the arm lumber, by placing one or more floored cloth frames side by side, A working floor or passage is formed.

  In addition, the width of the cloth frame with a floor is usually used in two types of 240 mm width and 500 mm width, and they are referred to as a small anti (also referred to as a small cloth board) and a large anti (also referred to as a large cloth board), respectively. .

  FIG. 4 shows two examples of a cloth frame with a floor. (a) is a small anti 25 and (b) is a large anti 26. Both are plan views. The small anti 25 in (a) is a 240 mm wide cloth frame with only one main material 30 having a width of 240 mm, and the large anti 26 in (b) has two main materials 30 having a width of 240 mm arranged side by side. It is shown that this is a cloth frame with a floor having a width of 500 mm. In these examples, an embossing 71 is applied to the upper surface of the floor material portion 31 in order to prevent a worker from slipping when walking on a cloth frame with a floor. Moreover, in order to prevent the main material 30 from bending in the width direction, a crosspiece 70 is provided below the central portion of the main material 30.

  And the length of the horizontal frame of the building frame and the length of the arm timber have an inch size and a meter size, but the inch size usually has three types of 610mm, 914mm and 1219mm, and the meter There are usually three types of sizes, 600 mm, 900 mm, and 1200 mm.

  Therefore, normally, when installing a cloth frame with a floor as a work floor and a passage of a frame scaffold, a large anti (500 mm width) is used to form a width of 600 to 610 mm, and 900 to 914 mm. To form a width, one large anti (500 mm width) and one small anti (240 mm width) are placed side by side, and two large antis (500 mm width) are formed to form a width of 1200 to 1219 mm. They will be placed side by side.

  FIG. 5 shows three examples when the cloth frame 11 with a floor is installed as a work floor and a passage between the horizontal frames 3 of adjacent building frames. (a) is an installation example with a width of 600 to 610 mm, (b) is an installation example with a width of 900 to 914 mm, and (c) is an installation example with a width of 1200 to 1219 mm. Each is an enlarged view (plan view) of the vicinity of the horizontal rail 3 when the cloth frame 11 with a floor is installed between the horizontal rails 3 of adjacent building frames. (a) 600-610 mm width from one large anti 26 (500 mm width), (b) 900-914 mm width from one large anti 26 (500 mm width) and one small anti 25 (240 mm width), And it is shown that the 1200 to 1219 mm width of (c) is formed from two large anti-26 (500 mm width).

  Furthermore, in the framework scaffold, the stairs are frameworkd so that workers can assemble or disassemble the framework scaffold or move up and down in the framework scaffold, regardless of whether it is a building scaffold or a tight scaffold. Need to be incorporated into the scaffold. In this case, the stairs can be incorporated into the frame scaffold by replacing one or two of the floor-attached cloth frames in the upper stage scaffold, instead of being replaced by a staircase member to which a gripping fitting is attached.

  FIG. 6 shows two examples (plan view) when a stepped member 75 is incorporated, taking a 900 to 914 mm wide frame scaffold as an example. The staircase member 75 can be incorporated on either the road side or the building side as shown in (a) and (b). In both cases (a) and (b), the cloth frame 11 with a floor is adjacent to each other with a large anti 26 having a width of 500 mm and a small anti 25 having a width of 240 mm arranged in parallel in the horizontal direction. It was spanned between the crosspieces 3 of the building frame, and the small anti 25 remained as a passage as it was, and the staircase member 75 was incorporated in the place where there was the large anti 26 (500 mm width). I understand.

  Here, when the staircase member 75 is incorporated, the remaining small anti-layer 25 becomes a passage, but a staircase opening is formed in the scaffold at the upper stage of the staircase.

  Therefore, when the staircase member is installed, the remaining cloth frame with the floor becomes a passage, but in this state, from the non-elevator side end of the staircase and the side surface of the remaining cloth frame with the floor, May fall into the staircase opening.

  For this reason, a staircase opening handrail is installed on the non-elevator side end of the staircase and the remaining side surface of the cloth frame with the floor so that the worker does not fall into the staircase opening.

  FIG. 7 is a front view showing an example of a staircase opening handrail.

  The staircase opening handrail 32 includes a girder member 33 having gripping metal fittings 50 at both ends, a frame-shaped handrail frame composed of two left and right support members 34, an upper rail member 35, and a middle rail member 36, It consists of a rotating handrail material 39 that is rotatably mounted in the horizontal direction between the balustrade material 35 and the middle balustrade material 36, and has a vertical column fixing bracket 38 in the middle. Both are fixed perpendicular to the girders. Here, the frame-shaped handrail frame composed of the left and right support columns 34, the upper rail material 35, and the middle rail material 36 prevents the worker from falling from the side surface of the cloth frame 11 with the floor, A rotating handrail material 39 that is rotatably mounted in the horizontal direction between the upper and lower handrail members 35 and 36 prevents a worker from falling from the end of the staircase on the non-elevating side. become.

  FIG. 8 and FIG. 9 show an example when the staircase opening handrail is attached to a building frame type scaffolding made of a torii frame. 8 is a plan view, and FIG. 9 is a left side view.

  By hooking the holding metal fittings 50 provided at both ends of the girder 33 of the staircase opening handrail 32 to the horizontal rails 3 of the adjacent torii frame, the stairway opening handrail 32 is placed between the horizontal rails 3 of the adjacent torii frame. Install in parallel with the cloth frame 11 with a floor. Then, the rotating handrail material 39 attached between the upper handrail material 35 and the middle handrail material 36 is rotated in the horizontal direction and pulled out, and the vertical column fixing bracket 38 provided in the middle of the rotating handrail material 39 is connected to the torii gate. Fix to the vertical column 2 of the frame.

  Here, the rotating handrail material 39 of the staircase opening handrail 32 is fixed at right angles to a frame-shaped handrail frame composed of two left and right support members 34, an upper rail material 35, and a middle rail material 36. Rather than being fixed, it is the mainstream that is fixed obliquely. In other words, the rotating handrail material 39 of the staircase opening handrail 32 is not fixed at a right angle but fixed obliquely with respect to the girder 33 laid between the horizontal rails 3 of the adjacent torii frame. However, it has become mainstream. This is because when a worker who has walked a passage made of a wide cloth frame with a floor reaches a portion where a staircase is installed, it is necessary to change the course to a passage made of a narrow cloth frame 11 with a floor. This is because it is necessary to secure the passage width as wide as possible. The reason for this will be described with reference to the drawings.

  FIG. 10 is a cross-sectional plan view taken along the line B-B in FIG. 9, and is an example in which the rotating handrail material 39 of the staircase opening handrail 32 is fixed at a right angle to the frame-shaped handrail frame. A stiffener called cricket 41 is provided in the upper part inside the torii frame. As long as the worker walks in the center of the passage made of a wide cloth frame with a floor, the cricket 41 will not interfere with walking. Absent. However, when the course is changed from a wide cloth frame with a floor to a narrow cloth frame 11 with a floor, if the rotating handrail material 39 of the staircase opening handrail 32 is installed at a right angle, the post material of the cricket 41 and the handrail frame Since the space between 34 is narrow, the passage width becomes extremely narrow.

  In contrast, FIG. 11 is a cross-sectional view taken along the line B-B in FIG. 9, and is an example in which the rotating handrail material 39 of the staircase opening handrail 32 is fixed obliquely with respect to the frame-shaped handrail frame. A stiffener called cricket 41 is provided in the upper part inside the torii frame. When the course is changed from the wide floored cloth frame to the narrow floored cloth frame 11, the staircase opening handrail 32 rotates. Since the handrail material 39 is installed obliquely, the space between the cricket 41 and the support material 34 of the handrail frame is widened. Therefore, the passage width can be increased.

  However, when the rotating handrail material 39 of the staircase opening handrail is obliquely fixed with respect to the frame-shaped handrail frame in this way, a triangular gap 43 is formed at the end portion on the non-lift door side. Since there is a possibility that an operator will fall into the triangular gap 43 and fall down, and there is a possibility that the tool may fall to the lower stage from the triangular gap 43. A triangular gap plugging material is installed on the triangular gap 43.

  Patent Document 1 has two gripping metal fittings on the first side opposite to the side rail of the building frame that hits the non-elevator side end of the frame scaffold, and makes a right angle with this first side, A triangular gap closing material has been proposed that has a hook-shaped latch on the second side of the stairway opening that faces the girder of the stairway opening handrail in parallel.

  FIG. 12 is an example in which the triangular gap closing material proposed in Patent Document 1 is fixed to a triangular gap formed at the end of the non-lift port side, (a) is a plan view, and ( b) is a front view taken along line AA in (a).

  The triangular gap plugging material 44 is formed by connecting two gripping metal fittings 50 provided on the first side 45 facing in parallel to the horizontal frame of the building frame to the non-elevating side end of the frame scaffold. 3, the hook-shaped latch 48 provided on the second side 46 facing the parallel member 33 of the staircase opening handrail of the stairway opening is placed on the stirrer material 33 of the stairway opening handrail, Formed at the end of the non-lift door side by placing the side surface of the cloth frame 11 with the floor installed parallel to the girder material 33 of the staircase opening handrail on the restraining protrusion 49 of the hook-shaped latch 48 It closes the gaps between the triangles.

JP 2002-30805 A

  However, when the triangular gap plugging material 44 proposed in Patent Document 1 is installed, the two gripping metal fittings 50 provided on the first side 45 of the triangular gap plugging material 44 are connected to the horizontal rail of the building frame. 3, the hook-shaped latch 48 provided on the second side 46 is placed on the girder 33 of the staircase opening handrail, and further, the staircase opening is formed on the restraining protrusion 49 of the hook-shaped latch 48. It is necessary to place the side face of the cloth frame 11 with a floor installed in parallel with the handrail girder 33.

  That is, in order to install the triangular gap closing material 44 proposed in Patent Document 1, it is necessary to incorporate it when assembling the work scaffold, and conversely, when disassembling the work scaffold, they are installed in parallel. It is necessary to remove the cloth frame 11 with the floor first.

  Further, as shown in FIG. 6, since the staircase member 75 can be incorporated on either the road side or the building side, the triangular gap 43 formed at the end portion on the non-lift door side has an oblique side when viewed from above. There are two types: appearing on the left and appearing on the right. However, the triangular gap plugging material 44 proposed in Patent Document 1 has a special shape in the hook-shaped latch 48 provided on the second side 46 facing the beam member 33 of the staircase opening handrail of the stairway opening in a special shape. Therefore, the triangular gap plugging material 44 cannot be turned over and used. Therefore, the triangular gap plugging material 44 proposed in Patent Document 1 needs to be prepared in two types when the oblique side 47 appears on the left and on the right when viewed from above.

  The present invention relates to a triangular gap closing material for closing a gap formed at a non-elevating side end of a staircase opening of a frame scaffold used in a construction site or the like, in order to solve such a problem. The present invention provides a triangular gap plugging material that can be easily installed and used upside down without being bound by the time of assembly or disassembly of the frame scaffold, and this gap plugging material It is an object to provide a framework scaffold incorporating the above.

  In order to solve the above-described object, the present inventors have made various studies, and as a result, have obtained the findings shown in the following (a) to (f).

  (a) The triangular gap closing material proposed in Patent Document 1 has a first side that is parallel to the horizontal beam of the building frame that hits the non-elevator side end of the frame scaffolding, and is perpendicular to the first side. And the second side is the side facing the stairs opening handrail parallel to the beam of the staircase opening. And in order to close the triangular gap formed at the end of the non-elevating door side, the procedure for installing the triangular gap closing material is to attach the two grip fittings attached to the first side to the horizontal frame of the building frame After that, after placing the hook-shaped latch provided on the second side on the girder of the staircase opening handrail, the floor parallel to the girder of the staircase opening handrail is mounted on the protrusion of the hook-shaped latch. It will be fixed by placing the side of the fabric frame.

  However, in this procedure, it is not possible to install a triangular gap-closing material before the cloth frame with a floor parallel to the girder of the staircase opening handrail is bridged between the crosspieces of the adjacent building frame or the arm lumber. .

(b) Make it possible to install a triangular gap-closing material before the floor-mounted cloth frame parallel to the girder of the staircase opening handrail is bridged between the crosspieces of the adjacent building frame or the arm lumber. To do this, reverse the procedure and attach it to the girder of the staircase opening handrail first. In other words, the side facing the girder of the staircase opening handrail of the stairway opening of the frame scaffolding is the first side, is perpendicular to this first side, and is located on the side of the building frame or on the side of the arm lumber The side may be the second side. And a clamp etc. should just be installed in the 1st edge or its extension part as an attachment metal fitting for attaching the triangular gap closing material to the girder material of the stairway opening handrail of a staircase opening. At this time, if the triangular gap closing material is attached so as to be rotatable in the vertical direction with the mounting bracket as a horizontal axis, the installation angle of the triangular gap closing material can be adjusted.

  In this way, by attaching the triangular gap plugging material to the girder of the staircase opening handrail of the staircase opening, even after the cloth frame with the floor parallel to the girder of the stairway opening handrail is bridged, A gap closing material can be attached to close a gap formed at the end of the stairway opening on the non-lift port side. It is also possible to assemble or dismantle the frame scaffolding with the triangular gap closing material attached to the stair opening handrail girder of the stair opening.

Therefore, such a triangular gap closing material can be installed and removed at any time, so there is no need to worry about the order of installation and removal.
(c) In addition, the triangular gap closing material proposed in Patent Document 1 has a floor after the first side is attached to the crosspiece of the building frame and the second side is placed on the girder of the staircase opening handrail. It is possible to close the gap formed at the end portion on the non-elevating / lowering opening side of the staircase opening only after the labor of placing the side surface of the cloth frame is taken. However, the side facing the stairs opening handrail parallel to the girder of the staircase opening is defined as the first side, the side perpendicular to the first side and the side located on the side of the building frame or on the side of the arm timber is the second side. In the case of a triangular gap closing material as the side, it is only necessary to place the second side on the crosspiece or arm timber of the building frame that forms the frame scaffold, so it is necessary to provide a gripping member on the second side Absent.

  Further, in the case of the triangular gap closing material having the first side as the side facing the girder of the staircase opening handrail of the stairway opening portion as described above, it can be used even if it is turned over. There are two types of gaps in the triangle formed at the end of the non-elevator side, when the hypotenuse appears on the left and when it appears on the right when viewed from the top. It is sufficient to prepare only one type of gap plugging material.

(d) In order to securely fix the triangular gap plugging material on the gap formed at the end of the stairway opening on the non-elevator side, it is opposed to the staircase handrail girder parallel to the staircase opening. In addition to the mounting bracket of the first side to be extended or an extension thereof, a fixing auxiliary bracket that can fix the gap closing material to the girder of the staircase opening handrail may be further provided on the first side. It is preferable that the fixed auxiliary metal fitting has a U-shaped cross section and can be rotated in the vertical direction with the fixed auxiliary metal fitting as a horizontal axis . Alternatively, one or two or more number wire holes are provided in the material portion of the gap plugging material, and the number wire is passed through this, and the wire is attached to the crosspiece of the building frame or the arm wood or the girder material of the staircase opening handrail. This also makes it possible to reliably fix the triangular gap plugging material on the gap formed at the non-lift port side end of the staircase opening.

  (e) Then, on the hypotenuse of the triangular gap plugging material, the embossed surface of the material part is prevented so that the operator does not slip and fall when the worker walks on the triangular gap plugging material. Processing or slip processing may be performed. In addition, it is preferable to provide a skirting board so that the foot does not slip and fall. The baseboard is preferably provided not only on the oblique side but also on the first side. In particular, when the baseboard is provided on both sides of the oblique side and / or the first side of the triangular gap plugging material, the baseboard is provided even when used upside down. When a worker walks on the top, he / she does not slip and fall. In other words, if the three-dimensional shape of the gap plugging material is vertically symmetrical with respect to the horizontal plane, a triangular gap plugging material can be used without distinguishing between the front and the back, which is preferable.

  (f) In order to facilitate transport of the triangular gap closing material, it is preferable to provide one or more handle holes in the material portion of the gap closing material.

The present invention has been completed based on such findings, and the gist of the following (1) to (6) gap closing material and (7) framework scaffold. Hereinafter, (1) to (7) may be collectively referred to as the present invention.

The gap closing material 44 is a substantially triangular material in which the first side 45 and the second side 46 form a right angle, and the first side 45 is parallel to the beam material of the staircase opening handrail of the stairway opening of the frame scaffold. In contrast, the second side can be placed on the crosspiece or arm timber of the building frame that forms the framework scaffold. Then, on the extension of the first side clamping is employed as a mounting bracket 51 which can be attached to the gap closing member 44, but since the clamp has a bolt 53 and a nut 54, the horizontal axis of this clamping The gap closing member 44 can be rotated in the vertical direction .

  Here, the first side 45 is further provided with a fixing auxiliary metal fitting 52 having a U-shaped cross section, and the gap closing member 44 can be fixed to the beam member 33 of the staircase opening handrail. Since the fixing auxiliary metal fitting 52 has the bolt 53 and the nut 54, it can rotate. Two wire holes 55 are provided in the material portion of the gap closing material 44. A base board 60 is provided on the hypotenuse 47 and / or the first side 45 of the triangular gap closing member 44. Further, a handle hole 56 is provided in the material portion of the gap closing material 44. The auxiliary fixing metal fitting 52, the wire hole 55, the base board 60, and the handle hole 56 are not necessarily required, but are preferably installed for the following reasons.

That is, the fixing auxiliary metal fitting 52 is fitted in the staircase opening handrail girder 33 by rotating the gap plugging material 44 in the vertical direction around the horizontal axis of the bolt 53 of the mounting bracket 51, so that the gap plugging material 44 is staircased. It can be fixed to the girder 33 of the open handrail. When there is a hole 55 for the number wire, a number line (not shown) can be passed through it, and the number line can be attached to the crosspiece 3 of the horizontal frame 3 of the building frame or the handrail 33 of the staircase opening handrail.
