Description

  The present invention relates to a fall prevention device that closes an opening of a frame scaffold temporarily installed at a construction site or the like to prevent the fall.

  Frame scaffolds generally used in the construction industry, etc. are torii-type and gate-shaped building frames arranged in parallel at predetermined intervals, and the opposing building frames are cloth plates (scaffolding plates) and X at their upper and lower ends. They are connected by braces (crossing crosses) intersecting in the shape of a letter, and the same building frame is added upward using a joint above and assembled to the required height.

  However, since a large opening is created between the diagonal bar below the brace and the fabric board attached so as to connect the lower ends of the building frames, the worker falls off the foot, Occupational accidents such as dropping components have occurred.

  From such a background, it is necessary to install a horizontal rail, a skirting board, a mesh sheet or the like so as to close the opening, and various fall prevention tools and methods have been proposed.

  For the purpose of closing the opening, Patent Document 1 describes an example using a crossing bar with a handrail. In this example, handrails by pipes that are locked in the vicinity of the lower end of the crossed bar that is X-shaped in the open state and are stretched horizontally are provided with through-holes in the slanted-up pieces provided at the left and right ends. It is provided so that each bar can be inserted and folded so that it can overlap with the crossing bars.

  By this crossing bracing with a handrail, it is possible to easily hand over or remove the handrail simultaneously with the bracing, and if the handrail is positioned and attached to the foot, it is possible to prevent the operator from falling.

  As an example of a baseboard, a baseboard scaffolding base as described in Patent Document 2 has been proposed. This skirting board is attached to the main body part that forms a strip-shaped metal plate into a plate shape, and both ends in the longitudinal direction of this main body part, and a convex part and a concave part are formed at the end opposite to the side connected to the main body part. Framed scaffolding, which is composed of a connecting part and an arc-shaped leaf spring scissors that are attached to one side of the convex part of the connecting part. It is to be attached to.

  With this skirting board, a rising part is formed on the side of the fabric frame with a plate, so it is possible to prevent accidents caused by falling off of the foot or accidental dropping of tools and equipment, and to improve safety at the construction site. .

  On the other hand, as an example of a sheet-like fall prevention tool, a fall prevention structure as described in Patent Document 3 has been proposed. The structure consists of a flexible vertical sheet material and a horizontal sheet material combined to form a fall prevention sheet, and a plurality of overhang brackets are attached to the scaffold body at appropriate intervals, and between the pillars of the scaffold body and overhang brackets. Horizontal support bars are installed between them, and both the upper and lower ends and connecting portions of the fall prevention sheet are attached to these horizontal support bars, and the fall prevention sheet is stretched in an L shape on the scaffold main body and the extension bracket.

  With the above-described fall prevention structure, even if an operator or the like falls, it can be prevented from jumping out of the scaffold with the vertical sheet, and the horizontal sheet can prevent the fall.

  However, in the crossing with the handrail of Patent Document 1, since only the handrail is stretched over the opening of the brace and the cloth board, even if it is effective in preventing the operator from falling, a tool or a small member Can not prevent the fall.

  In the skirting board for frame scaffolding of Patent Document 2, since the skirting board main body is made of a metal plate, the weight of the skirting board itself becomes heavy. It is not easy to handle long metal plates in a framework scaffold that is not wide enough, and it is not efficient in terms of transporting equipment.

  The fall prevention structure described in Patent Document 3 seems to have a high effect of preventing the fall of workers and articles, but in order to stretch the fall prevention sheet, the number of equipment such as brackets and horizontal support bars increases. It takes time to assemble and disassemble the scaffold.

  It is normal to keep the equipment cost of the framework scaffolding low at the construction site, etc., and the number of equipment is as small as possible, it can be easily installed with light weight, and it is difficult to disseminate unless it is inexpensive.

  The purpose of the skirting board is to provide an inexpensive fall prevention sheet that reliably closes the opening between the diagonal bar of the brace and the cloth plate to prevent the fall of workers and tools, etc., and is light and easy to install. This is realized by only having a flexible sheet and a bar-shaped crosspiece member and facilitating the attachment to the scaffold.

  FIG. 1 shows a baseboard sheet 10 according to a first embodiment of the present invention installed on the beam side and the frame side of a frame scaffold 1. A frame scaffold 1 includes a plurality of gate-shaped building frames 2 erected in parallel, the building frames 2 are connected by braces 4, and a cloth plate 3 is placed between the upper ends of the building frames 2 to provide a scaffold for workers. It is what.

  The building frame 2 mainly includes a pair of building pipes 2a parallel to the vertical direction and a horizontal crosspiece pipe 2b connecting the vicinity of the upper end of the building pipe 2a, and these are constituted by circular steel pipes. The building frame 2 shown in this embodiment has a height of about 170 cm, a width of about 122 cm, an installation interval of about 183 cm, and the building pipe 2a is a steel pipe having a diameter of 42.7 mm.

  Stepped pipe-shaped joints 5 with thick middles are inserted into the upper ends of the two building pipes 2a of the building frame 2, respectively, and the same building frame 2 is connected and inserted on the upper side. The frame scaffold 1 is assembled.

  The brace 4 is a bar that is flatly crushed at both ends of a circular pipe and is pivotally attached to the center of its length so that it can pivot around its length. Handing over. The two building pipes 2a of the building frame 2 are provided with claw pins called gravity locks 2c projecting inward and downward at two locations, and are provided at the ends of the brace 4. The brace 4 is fixed by inserting the gravity lock 2c into the through hole. The claw provided near the tip of the gravity lock 2c is urged by a spring from the inside of the pin. When the end of the brace 4 is inserted all the way into the back, the claw rises to prevent the brace 4 from coming off. ing. The position of the gravity lock 2c shown in the present embodiment is located approximately 33 cm above the lower end of the cloth plate 3 below the gravity lock 2c.

  The cloth plate 3 is formed into a box shape by bending the four sides of a rectangular thin steel plate downward, and hooks are provided at the four corner positions to be hung between the horizontal beam pipes 2b of the building frame 2 to form a step board. The lower end of the four sides is bent downward depending on the equipment manufacturer, but it is further bent to prevent injury and reinforcement of the operator, and a strip-shaped reinforcing bar 3a is provided across the opposite sides of the bent part. Some are also available.

  In order to attach the skirting sheet 10, a horizontal beam 6 is provided between the building pipes 2a as a bar-shaped horizontal beam member. As shown in FIG. 3, the horizontal rail 6 is formed by flattening both ends of a circular pipe in the same manner as the brace 4 and providing a through hole on the flat surface, and below the building frame 2 erected in parallel. After attaching the brace 4 between the gravity locks 2c, it is inserted and fixed so as to overlap. The horizontal beam 6 shown in this embodiment is a steel pipe having a diameter of 27.2 mm and a plate thickness of 1.6 mm, and the pitch of the end through holes is about 183 cm corresponding to the installation span of the building frame 2.

  FIG. 7 shows a rear view of the skirting sheet 10 according to the present embodiment. The skirting sheet 10 mainly includes a sheet main body 11 and fixing means provided at the lower edge portion 12 thereof, and gripping means provided at the upper edge portion 13.

  For the sheet body 11, a horizontally long rectangular mesh sheet made of a material such as polyester is used. By using a mesh sheet, it is flexible and can be easily folded, and is lightweight and easy to handle.

  Further, it is desirable that the material of the sheet has strength, flameproofness, and translucency that cannot be easily broken. If it has flameproofness, it is hard to burn even if the welding sparks come into contact with it, and if it has translucency, the brightness in the frame scaffold 1 can be secured and work can be performed safely. The lateral length of the sheet body 11 is preferably about the inner dimension between the building frames 2 arranged side by side. In this embodiment, the sheet length is about 176 cm and the height is about 57 cm. Moreover, although the mesh sheet was used in the present Example, of course, you may use a sheet | seat without a hole for the purpose of shielding.

  Three hook fittings 14 are provided at intervals along the edge of the lower edge 12 near the lower edge 11a of the seat body 11 as fixing means. The hook metal fitting 14 is formed by bending a steel plate into a U-shape, and as shown in the right side view of the sheet in FIG. The abutment plate 15 is applied to the opposite surface of the sheet, the sheet is sandwiched between the hook metal fitting 14 and the abutment plate 15, and fixed with rivets. The height protruding from the sheet surface of the hook metal fitting 14 is set to a dimension that can be sufficiently hooked to the bent portion below the side surface of the cloth board. In this embodiment, the height is 40 mm and the metal fitting width is 50 mm. Further, although an example in which three hook fittings 14 are provided has been described, a single member having a long L-shaped section along the lower edge 11a may be used, and the attachment method to the sheet main body 11 may be performed by welding or stitching.

  The upper edge portion 13 near the upper edge 11b of the seat body 11 is provided with three magic tapes (registered trademark, the same applies hereinafter) 16 as fastening members at positions immediately above the hook fitting 14 as gripping means. Each of the magic tapes 16 has a strip shape with a width of 100 mm, and the width direction is set to the length direction of the upper edge 11b of the sheet body 11, and is sewed and fixed to the sheet body 11 from the upper edge 11b to slightly below the middle of the sheet. In this embodiment, a magic tape having both hooks and loops that are not distinguished between males and females was used, and the length from the upper end to the lower end of the magic tape 16 shown in FIG. 7 was about 42 cm.

  By providing the magic tape 16 downward from the sheet upper edge 11b as described above, when the sheet upper edge 11b is folded downward, the inner facing surfaces thereof are stuck together and fixed. The belt-like magic tape 16 is provided so as to be slightly longer than the middle of the sheet so that the folding length is not limited.

  On the other hand, flaws of the mesh sheet are appropriately prevented at the left and right edges of the front surface of the sheet body 11, and eyelets 18 are respectively attached to the lower corner and slightly below the middle of the sheet to provide through holes. The eyelet is fixed through a string 19 so that other objects and the sheet can be tied and fixed.

  Next, a method for attaching the baseboard sheet 10 configured as described above to the frame scaffold 1 will be described.

  The baseboard sheet 10 according to the present invention is used upward from the second stage of the frame scaffold 1 that is normally assembled. First, the lower edge 11a of the sheet body 11 is hung along the side of the cloth plate 2 on the spar side and the case side, and the hook metal fitting 14 provided on the lower edge 12 is hooked on the bent portion below the side of the cloth plate 2. . Then, in order to prevent the hook metal fitting 14 from being detached, the sheet upper edge 11b is placed on the horizontal rail 6 provided between the building pipes 2a and is folded downward from the outside of the frame scaffold 1 and is folded with the magic tape 16 facing the folded inner side. Fix it. At this time, the sheet can be stretched in a tensioned state by pulling until the upper edge 11b of the sheet is fixed. Moreover, since the operator who spreads hooks the hook metal fitting 14 to the bending part of the side surface lower end of the cloth board 2 in which he / she rests, it becomes an unsafe action to look down from the cloth board 3. Therefore, it is desirable that there is an auxiliary worker at the lower stage to assist or check for hooking.

  Since the belt-like magic tape 16 is provided from the upper edge 11b of the sheet downward to a position slightly below the middle of the sheet, the folding length is not limited and the sheet can be expanded with an appropriate tension. In this embodiment, the distance between the lower end of the cloth plate 3 and the horizontal beam 6 is about 33 cm, and the open height of the baseboard sheet 10 is about 57 cm. Therefore, the folded length of the upper edge 13 wrapped around the horizontal beam 6 is about It became 20cm. Moreover, even if the position of the horizontal beam 6 is different using different building frames, the folding length can be adjusted and attached. Further, in this embodiment, the magic tape 16 with no distinction between male and female is used, so there is no need to determine the positions of the female and male tapes, and the processing is not troublesome.

  Next, the eyelet 18 and the string 19 provided on the left and right edges of the seat body 11 are respectively bound to the adjacent building pipe 2a. By doing so, even if the hook metal fitting 14 is removed or the magic tape 16 is removed, there is no fear that the skirting sheet 10 will fall or be blown away by the wind. In addition, since the sheet body 11 can be appropriately tensioned in the left-right direction when being bound, the gap between the building pipe 2a and the edge can be eliminated, and safety is improved.

  With the above contents, the skirting sheet 10 according to the present embodiment can be spread on the frame scaffold 1. Since the lower edge portion 12 of the seat body 11 is fixed with a hook metal fitting 14 that is simply hooked, and the upper edge portion 13 is folded back to the horizontal rail 6 and fixed with a magic tape 16, the attachment is very easy. Moreover, since the skirting board sheet 10 can be easily removed in the reverse procedure, there is no burden on the operator.

  In the above embodiment, an example in which the magic tape 16 is provided on the surface near the upper edge 11b of the sheet is shown. However, a belt with a magic tape protrudes from the vicinity of the upper edge 11b, and the horizontal rail 6 is held by the belt. You may make it do.

  Next, a second embodiment of the present invention will be described. FIG. 8 shows a second embodiment of the present invention in which a baseboard sheet 30 is provided on the beam side and the frame side of the frame scaffold 1. The structure of the frame scaffold 1 is substantially the same as that of the first embodiment. However, a cloth plate 3 provided with strip-like reinforcing bars 3a with the lower ends of the side faces across the opposite sides is used.

  A rear view of the skirting sheet 30 according to the present embodiment is shown in FIG. The skirting sheet main body 31 uses a mesh sheet in substantially the same manner as in the first embodiment. The lower edge 31a is prevented from fraying over its entire length, and the lower edge portion 32 is appropriately positioned slightly above the lower edge 31a. The eyelet 34 is attached at intervals and a through hole is provided. The eyelet 34 is fixed through a string 35 so that the sheet can be tied to another object.

  The upper edge portion 33 near the upper edge 31b of the sheet body is formed as a bag sewing shape along the edge as a gripping means. First, the upper edge 31b of the sheet is folded back and overlapped by about 150 mm parallel to the edge, and stitched parallel to the crease near the edge. By doing so, it becomes the bag sewing shape which both right and left ends opened.

  In the left and right edges of the sheet main body 31, two through-holes for fraying prevention processing and eyelets 34 are provided in the same manner as in the first embodiment, and a string 35 is attached.

  The skirting sheet 30 as the second embodiment is configured as described above. The finished dimensions of the baseboard sheet 30 shown in this example were about 176 cm in horizontal length and about 39 cm in height. Next, the attachment method will be described.

  First, since the upper edge portion 33 of the baseboard sheet 30 of this embodiment has a bag-sewn shape, the horizontal rail 6 as a horizontal rail member is inserted into the upper edge portion 33 in advance. Then, the horizontal rail 6 passed through is spanned between the construction pipes 2a on the beam side and the frame side and fixed. With the above configuration, the upper edge portion 33 is fixed to the cross rail 6 by the gripping means, and the lower edge portion 32 hangs downward along the side surface of the cloth board 3.

  Next, an operator at the lower stage of the stage to which the skirting sheet 30 is attached pulls the lower edge 32 of the sheet hanging down from above, and the reinforcing bar 3a on the back side of the overhead cloth board with the string 35 provided on the lower edge 32. Tie to and fix. At that time, it is desirable that the side surface of the cloth board 3 is in contact with the sheet body 31 without slack so as not to impair the function as a skirting board. If the length of the string 35 provided on the lower edge 32 and the binding place are adjusted accordingly. Good. In this embodiment, the distance between the lower end of the cloth plate 3 and the cross rail 6 is about 33 cm, and the height of the baseboard sheet 30 is about 39 cm, so that the eyelet 34 and the string 35 of the lower edge 32 are made of cloth. The plate 3 is positioned at a bent portion below the side surface, and is fixed to a reinforcing bar 3a at the place. In addition, the eyelet 34 and the string 35 provided on the left and right edges of the seat are the same as those of the first embodiment in the attaching method and the effect.

  With the above contents, the skirting sheet 30 according to the present embodiment can be spread on the frame scaffold 1. The upper edge 33 of the skirting sheet 30 is fixed with a previously inserted horizontal beam 6 and the lower edge 32 is fixed with a string 35 to the reinforcing beam 3a of the cloth board 3, so a tool is used. Without this, the skirting sheet 30 can be easily extended. Further, it is only necessary to fold back the sheet itself or to provide the eyelet 34 and the string 35, and the baseboard sheet can be manufactured at a low cost.

  Next, a third embodiment of the present invention will be described. FIG. 13 shows a third embodiment of the present invention in which a baseboard sheet 50 is provided on the beam side and the frame side of the frame scaffold 1. Although the structure of the frame scaffold 1 is the same as that of Example 2, the gravity lock 2d of the building pipe 2a is slightly higher than that of Example 2, and the distance from the lower end of the cloth plate 3 is about 41 cm.

  FIG. 16 shows a rear view of the skirting sheet 50 according to this example. The skirting sheet main body 51 uses a mesh sheet in substantially the same manner as in the first embodiment. The lower edge 51a is prevented from fraying over its entire length, and the lower edge 52 is appropriately positioned slightly above the lower edge 51a. The eyelet 54 is attached at intervals and a through hole is provided. The eyelet 54 is fixed through a string 55 so that other objects and the sheet can be tied and fixed. These configurations are the same as those in the second embodiment.

  The upper edge portion 53 near the upper edge 51b of the seat body is formed as a bag sewing shape along the edge as a gripping means. First, the sheet upper edge 51b is folded downward about 240 mm parallel to the edge and overlapped, and stitched parallel to the crease near the edge. Furthermore, it is stitched in parallel with the crease in the vicinity of the middle of the folding allowance. By doing so, a bag-stitched gripping means having both left and right ends opened in two upper and lower stages is constituted. On the other hand, on the left and right edges of the sheet main body 51, two fraying prevention treatments and two through-holes with eyelets 54 are provided in the same manner as in the second embodiment, and a string 55 is attached.

  The skirting sheet 50 as the third embodiment is configured with the above contents. The finished size of the baseboard sheet 50 shown in this example is about 176 cm in horizontal length, the length from the upper edge of the upper sewed shape to the lower edge 51a is about 48 cm, from the upper end of the lower sewed shape to the lower edge 51a The length of was about 39 cm.

  Next, the attachment method will be described. The upper edge portion 53 of the skirting sheet 50 of this embodiment has a two-step upper and lower bag stitch shape, and a horizontal beam 6 as a horizontal beam member is inserted into the upper level in advance and passed therethrough. Then, the cross rail 6 passed through is spanned and fixed between the gravity locks 2d of the construction pipes 2a on the beam side and the frame side. Then, since the positional relationship between the finished dimensions of the sheet and the crosspieces 6 and the cloth board 3 is substantially the same as in the second embodiment, the lower edge portion 52 and the left and right edges are tied and fixed in the same manner with the string 55.

  The construction and usage of the skirting board sheet 50 of this embodiment are substantially the same as those of the embodiment 2, but the upper edge 53 is formed in a two-stage bag sewing shape, so that the horizontal rail 6 and the skirting board sheet when stretched are stretched. The length between 50 lower edges 51a can be adjusted in two steps. That is, when the position of the gravity lock differs depending on the type of building frame, if the position is high, the horizontal rail 6 is inserted into the upper sewing portion of the upper edge 53, and if the lower position is lower, the lower sewing portion. By inserting the horizontal rail 6 into the sheet, it is possible to prevent the lower edge portion of the sheet from being left unnecessarily, and when fixing to the reinforcing rail 3a of the cloth board 3, it can be fixed at substantially the same position. Therefore, when the distance between the lower end of the cloth plate 3 and the cross rail 6 is about 33 cm as in the second embodiment, the lower stage is used so that the eyelet 54 and the string 55 in the lower edge 52 are in the same positions as in this embodiment. It becomes. In addition, when a lower sewed portion is used, the upper portion hangs down with an excess, but it may be appropriately fixed with a string or the like.

  In the skirting sheet 50 as the third embodiment of the present invention as described above, similar to Example 2, it is only necessary to fold the sheet itself and to process the eyelet 54 and the string 55, and to produce the skirting sheet at a low cost. At the same time, it can be attached to building frames with different gravity lock positions.

  The present invention described above is not limited to the above-described embodiments, and various modifications can be made within the scope of the gist. For example, the fixing means for the lower edge of the sheet and the gripping means for the upper edge are not limited to those described in this embodiment, and a configuration in which a string is provided as the fixing means and a magic tape is used as the gripping means may be used.
