Description

This idea relates to a structure using a beam frame.

Generally, temporary scaffolding is installed along the outer wall of various buildings such as buildings and structures, and is used by workers for repairs and painting. As a structure for temporary scaffolding, there is a structure in which a plurality of columns are arranged at predetermined intervals along the outer wall of a building, adjacent columns are connected by a beam frame, and a scaffold plate is fixed to the beam frame. .. In addition, if there is an entrance / exit in the building, the columns should be placed avoiding the vicinity of the entrance / exit, and a beam frame with a longer span than the others should be hung between the columns on both sides of the entrance / exit. An opening having a width that allows vehicles and the like to pass through is set (see, for example, Patent Document 1).

JP-A-2018-138717

The width required for the opening depends on the site where the temporary scaffold is used. When the width of the entrance / exit of a building is wide, a beam frame having a relatively long span is required because the distance between the columns located on both sides of the entrance / exit is wide. On the other hand, if the width of the doorway is not so wide, the distance between the columns is not so wide, so a beam frame with a long span cannot be used, and the length is relatively short according to the width of the doorway. Beam frame is required.

As described above, in the temporary scaffold using the conventional beam frame structure, for example, a beam frame having a total length of 7.2 m, a beam frame having a total length of 5.4 m, and a beam frame having a total length of 3.6 m are used depending on various site conditions. It was necessary to prepare a large number of a plurality of types of beam frames having different span lengths, such as a beam frame having a total length of 2.7 m. Procuring a large number of beam frames or storing them is not preferable because it leads to high cost.

Therefore, an object of this invention is to reduce costs related to procurement and inventory of members in a structure using a beam frame such as a temporary scaffold.

In order to solve the above problems, the present invention includes a plurality of columns in parallel, a longitudinal beam frame spanned between the columns, and fixing means for fixing both ends of the beam frame to the columns. In the structure provided with, the beam frame includes a plurality of divided beam members divided along the longitudinal direction and a connecting means for detachably connecting the opposing ends of the divided beam members. Adopted.

Here, the divided beam member includes an upper beam member extending in the longitudinal direction and a lower beam member located below the upper beam member, respectively, and the connecting means is provided on the upper beam member. It can be composed of a connecting means and a lower connecting means provided on the lower beam member.

Further, the upper connecting means may include a tubular member provided on one side of the split beam member and extending in the longitudinal direction, and an insertion member provided on the other side and inserted into the tubular member.

Further, the lower connecting means includes a first vertical through hole provided in one of the divided beam members, a second vertical through hole provided in the other, the first through hole, and the second through hole. It can be provided with at least one pin inserted into the.

In a structure using a beam frame such as a temporary scaffold, it is possible to reduce costs related to procurement and inventory of members.

An embodiment of this device is shown in FIGS. 1 to 8C. In the structure according to this embodiment, a plurality of columns 11 and 11 are arranged along the outer wall of the building at predetermined intervals, and the adjacent columns 11 and 11 are connected by a beam frame 20 and the beam frame 20 is connected. It is a structure for fixing the scaffolding plate 2 on which the worker walks. Further, around the scaffolding plate 2, a horizontal member or a diagonal member serving as a handrail is provided as needed.

In this embodiment, as shown in FIG. 1, the columns 11 are arranged in pairs on the side near the outer wall (inner side) and the side far from the outer wall (outer side) of the building. A plurality of sets of the two columns 11 are installed along the outer wall at required intervals. Both ends of the long beam frame 20 are fixed to the columns 11 by fixing means 30. That is, the support column 11 functions as a beam frame support portion 10 that supports both ends of the beam frame 20 in the longitudinal direction. The beam frame 20 is fixed to the inner support column 11 near the outer wall and the outer support column 11 on the far side, respectively, and two parallel beam frames 20 support both sides of the scaffolding plate 2 in the width direction. The lower end of the support column 11 is placed on the ground via the pedestal 12 and the height adjusting device 13. The pedestal 12 is composed of a flat plate-shaped member 12a and a male screw member 12b rising from the plate-shaped member 12a. The adjusting device 13 is composed of a nut member provided at the lower end 11a of the support column 11, and the height of the support column 11 can be adjusted by adjusting the screwing amount of the nut member with respect to the male screw member 12b. The support column 11 is composed of a tubular body having a circular cross section.

Here, various structures may be adopted as the fixing means 30, but in this embodiment, a structure using a wedge member is adopted. As shown in FIGS. 4A to 5, the fixing means 30 includes a locking portion 30a attached to the support column 11, a holder member 30b fixed to the end of the beam frame 20, a locking portion 30a, and a holder member 30b. It is provided with a connecting member 33 for connecting the above.

The locking portion 30a is composed of a flange 31 that projects and is fixed to the outer periphery of the support column 11. Since the support column 11 can be formed by appropriately connecting pipe bodies having a predetermined length, the flange 31 can be set to a required height by connecting the pipe bodies to which the flange 31 is welded at an appropriate position. Further, it is also possible to arrange a plurality of flanges 31 at predetermined intervals along the axial direction of the support column 11. The flange 31 is made of an annular metal plate having a predetermined thickness, and the support column 11 is inserted into a hole provided in the center thereof, and the edge of the hole and the outer periphery of the support column 11 are fixed by welding. The flange 31 is provided with a plurality of locking holes 32 around the axis of the column 11. In this embodiment, four locking holes 32 are provided in the equally divided directions around the axis of the column 11, so that the beam frame 20 can be fixed to the column 11 in all directions around the axis (every 90 °). However, the orientation and number of the locking holes 32 can be freely set. For example, the locking holes 32 may be provided on two sides of the support column 11 around the axis (every 180 °) or three sides around the axis (every 120 °).

As shown in FIG. 5, the holder member 30b is provided with a groove 35 cut to a predetermined depth in the horizontal direction at the tip thereof, and is provided with a fitting hole 36 penetrating in the vertical direction. The groove 35 is formed with a width slightly larger than the thickness of the flange 31, so that the flange 31 can enter the inside. The position of the through hole 36 and the position of the locking hole 32 match with each other in a state where the outer edge of the flange 31 is in contact with the bottom of the groove 35. The holder member 30b is supported with its upper and lower end faces of both sides of the groove 35 in contact with the outer surface of the support column 11. Further, the through hole 36 has a length slightly larger than the width of the connecting member 33 (the length connecting the front end 36b and the rear end 36a along the longitudinal direction of the beam frame 20) and the plate thickness of the connecting member 33. The width is slightly large (the width in the direction orthogonal to the longitudinal direction of the beam frame 20). Further, a retaining portion 37 is provided on the lower inner surface of the front end 36b of the fitting hole 36.

The coupling member 33 is inserted into the fitting hole 36 and the locking hole 32 in a state where the fitting hole 36 and the locking hole 32 are aligned in the vertical direction. As shown in FIG. 4C, the coupling member 33 includes a wedge portion 33b that enters the locking hole 32, a horizontal portion 33a that is connected to the upper portion of the wedge portion 33b and extends toward the rear end side, and a lower portion from the rear end of the horizontal portion 33a. It is a U-shaped member including an insertion portion 33c that extends to and enters between the outer edge of the flange 31 and the rear end of the fitting hole 36. The wedge portion 33b tapers downward, and the surface that abuts on the front end (outer surface of the strut 11) of the locking hole 32 is parallel to the axial direction of the strut 11 and abuts on the rear end of the locking hole 32. The surface is a tapered surface that is inclined with respect to the axial direction of the column 11. By the action of this tapered surface, the coupling member 33 is prevented from coming off. Further, at the lower end of the insertion portion 33c, a pin 33f is provided to prevent the coupling member 33 from coming off when the coupling member 33 is pulled up. Further, the front end 33d at the lower end of the insertion portion 33c also comes into contact with the stopper 37 at the lower end of the holder member 30b to prevent the connecting member 33 from coming off. The beam frame 20 and the support column 11 are connected by the connecting member 33.

The beam frame 20 is a longitudinal member that is hung between adjacent columns 11 and 11. In a general temporary scaffold, the distance between the columns 11 and 11 is approximately a specified length, and the entire temporary scaffold is unified. However, in places where people, vehicles, etc. pass under the beam frame 20, it is necessary to widen the space between the columns 11 and 11 to provide an opening for passage. The width W (see FIG. 1) required for this opening varies from site to site. Therefore, in order to cope with the spacing between the columns 11 and 11 that differ depending on the site, in the present invention, the beam frame 20 is divided into a plurality of divided beam members 20A and 20B along the longitudinal direction, and the divided beam members 20A, It is configured to include a connecting means J for detachably connecting the facing ends (hereinafter referred to as facing ends) of the 20Bs. The height H required for the opening (see FIG. 1) is adjusted by setting the position of the fixing means 30 with respect to the support column 11.

As shown in FIG. 1, the split beam members 20A and 20B include an upper beam member 21 extending in the longitudinal direction and a lower beam member 22 located below the upper beam member 21 along the upper beam member 21. There is. Further, the upper beam member 21 and the lower beam member 22 are connected by a vertical member 23 in a direction orthogonal to the longitudinal direction and an oblique member 24 in a direction forming an acute angle with respect to the longitudinal direction. Holder members 30b corresponding to the fixing means 30 are attached to the ends of the split beam members 20A and 20B on the support column 11 side (hereinafter, referred to as support column side ends). In this embodiment, the fixing means 30 is provided at the support end of each of the upper beam member 21 and the lower beam member 22, but a configuration in which the fixing means 30 is provided only on the upper beam member 21 is also conceivable. Further, the connecting means J for detaching the facing ends of the split beam members 20A and 20B is composed of an upper connecting means 40 provided on the upper beam member 21 and a lower connecting means 50 provided on the lower beam member 22. ing. The upper beam member 21, the lower beam member 22, the vertical member 23, and the diagonal member 24 are all made of hollow tubular members, and all of them have a circular cross section in the embodiment.

In this embodiment, as shown in FIG. 1, the beam frame 20 is composed of two divided beam members 20A, 20B, but this is composed of three or more divided beam members 20A, 20B .... Is also possible. FIG. 2 is a modification of FIG. 1, in which the beam frame 20 has a relatively long length in the longitudinal direction, that is, the first split beam member 20A and the first split beam member 20A in the longitudinal direction. An example of the second split beam member 20B having a short length is shown. Further, FIG. 3 is a further modification of FIG. 1, in which the beam frame 20 is also relative to the first split beam member 20A having a relatively long length in the longitudinal direction and the first split beam member 20A. An example of the second split beam member 20B having a short length in the longitudinal direction is shown. However, in the example of FIG. 3, the length of the first split beam member 20A on the right side in the drawing is shorter than that of the example of FIG. 2, and corresponds to a relatively narrow opening.

Here, as shown in FIGS. 6A to 7B, the upper connecting means 40 is a tubular member extending in the longitudinal direction provided on one of the split beam members 20A and 20B (in the embodiment, the second split beam member 20B side). It includes a 42 and an insertion member 41 provided on the other side (on the side of the first split beam member 20A in the embodiment) and inserted into the tubular member 42. The insertion member 41 is composed of a tubular member or a shaft-shaped member inserted into the end of the upper beam member 21 (denoted by the reference numeral 21a in the drawing) on the side of the first split beam member 20A. On the other hand, the tubular member 42 is formed by the end portion of the upper beam member 21 (denoted by the reference numeral 21b in the drawing) on the second split beam member 20B side, but is separate from the upper beam member 21. The tubular member 42 may be fixed to the end of the upper beam member 21 by welding or the like. The inner diameter of the tubular member 42 is set so that the insertion member 41 inserted therein fits into the tubular member 42 without rattling. The structure of the connecting means J configured by using the plug-in member 41 and the tubular member 42 is referred to as a plug-in type connecting structures 40a and 40b.

Further, the upper connecting means 40 includes a stopper device that determines the positions of the upper connecting means 40 with respect to each other in the longitudinal direction. The stopper device includes a contact member 43 provided on the upper beam member 21 on the first split beam member 20A side and a contact member 44 provided on the upper beam member 21 on the second split beam member 20B side. It is composed of. The abutting member 43 is composed of a receiving member 43b having a U-shaped cross section fixed to the upper beam member 21 by welding or the like, and a bolt 43a screwed into the female screw portion of the receiving member 43b. Further, the contacted member 44 is composed of an L-shaped member having an L-shaped cross section fixed to the upper beam member 21 on the second split beam member 20B side by welding or the like. When the head of the bolt 43a abuts on the end surface of the contacted member 44, further approach of the first split beam member 20A and the second split beam member 20B is restricted, and both are positioned in the longitudinal direction. Will be done.

Further, as shown in FIGS. 6A to 7B, the lower connecting means 50 has a first through hole 53 in the vertical direction provided in one of the first split beam member 20A and the second split beam member 20B, and the other. It includes a second through hole 56 in the vertical direction provided, and at least one pin 52 inserted into the first through hole 53 and the second through hole 56. In this embodiment, as shown in FIG. 7B, the first through hole 53 is provided in the first connecting member 51 provided in the first split beam member 20A, and the second connection provided in the second split beam member 20B. The member 55 is provided with a second through hole 56. The first connecting member 51 is a pair of pairs protruding in the same direction from the upper end and the lower end of the base portion fixed to the end portion of the lower beam member 22 (denoted by the reference numeral 22a in the drawing) on the first split beam member 20A side. It is a member having a U-shaped cross section with a connecting piece. The first through hole 53 is provided in a pair of connecting pieces of the first connecting member 51 and is vertically aligned so that one pin 52 can be inserted. The second connecting member 55 is a pair of pairs protruding in the same direction from the upper end and the lower end of the base portion fixed to the end portion of the lower beam member 22 (denoted by the reference numeral 22b in the drawing) on the second split beam member 20B side. It is a member having a U-shaped cross section with a connecting piece. The pair of connecting pieces are connected and reinforced by vertical ribs. The second through hole 56 of the second connecting member 55 is provided in the pair of connecting pieces, and the upper and lower positions are aligned so that one pin 52 can also be inserted.

The first connecting member 51 and the second connecting member 55 are aligned so that the first through hole 53 and the second through hole 56 are located in a straight line. The positioning of the lower connecting means 50 can be performed in a state where the upper connecting means 40 is already connected. Since the tubular member 42 having a circular cross section and the insertion member 41 can rotate relative to each other in a state where the upper connecting means 40 is connected, the first connecting member 51 of the lower connecting means 50 is connected. This is because the second connecting member 55 and the second connecting member 55 can swing in the depth direction of the paper surface shown in FIG. 6B. That is, the pair of connecting pieces of the second connecting member 55 can be inserted between the paired connecting pieces of the first connecting member 51, and the first connecting member 51 and the second connecting member 55 are longitudinally formed in the inserted state. This is because it can move (swing) relative to the direction orthogonal to the direction. If the pin 52 is inserted through the first through hole 53 and the second through hole 56 aligned in a straight line, the connection between the first split beam member 20A and the second split beam member 20B is completed. The pin 52 is held by the upper holding portion 54 provided on the vertical member 23 so as not to fall downward. The structure of the connecting means J configured by using the first connecting member 51 and the second connecting member 55 is referred to as a swing alignment type connecting structure 50a, 50b.

The lower connecting means 50 is formed by reversing the structures of the upper connecting means 40 and the lower connecting means 50 used in the above embodiment and using the plug-in member 41 and the tubular member 42. The swinging position-aligning connection structures 50a and 50b configured by using the first connecting member 51 and the second connecting member 55 may be adopted as the upper connecting means 40. Further, the plug-in type connection structures 40a and 40b may be adopted for both the upper connection means 40 and the lower connection means 50, and the swing alignment type connection structures 50a and 50b may be used for the upper connection means 40 and the lower connection means 50. It may be adopted for both. Further, a connecting means J having a configuration different from that of the connecting means J of each of the above embodiments may be adopted for the upper connecting means 40, the lower connecting means 50, or both.

Deformation examples of the beam frame 20 are shown in FIGS. 8A to 8C. FIG. 8A shows an example in which the beam frame 20 is composed of the first divided beam member 20A and the second divided beam member 20B having the same length as each other. FIG. 8B uses the first split beam member 20A and the second split beam member 20B having the same length as those in FIG. 8A, but the length of each split beam member is the aspect of FIG. 8A. Is shorter than. Further, in FIG. 8C, the length of each split beam member is further shorter than that in the embodiment of FIG. 8B. In the examples of FIGS. 8A to 8C, the fixing means 30 provided on the lower beam member 22 employs an abutting member that abuts on the side surface of the support column 11, but the upper beam is the same as in the above-described embodiment. The same fixing means 30 as the member 21 may be adopted. Further, it is also conceivable that the lower beam member 22 is connected to the upper beam member 21 by bending both ends in the longitudinal direction upward so that the fixing means 30 of the lower beam member 22 is omitted. Further, as the fixing means 30, it is also possible to adopt a structure other than the embodiments shown in FIGS. 3A to 5 above.

Another embodiment is shown in FIG. In this embodiment, the beam frame 20 shown in the above embodiment and the structure 1 using the beam frame 20 are applied to a temporary stage. As shown in FIG. 9, the structure 1 constituting the temporary stage has a plurality of columns 11 and 11 at predetermined intervals along a direction in which the plurality of columns 11 and 11 intersect with each other (hereinafter referred to as the other direction). It is arranged. In this example, two columns 11 are arranged in parallel along one direction, and three columns 11 are arranged in parallel along the other direction. Further, a beam frame 20 connects adjacent columns 11 and 11 in one direction. As a result, three sets of the assembly including the two columns 11 and 11 parallel in one direction and the beam frame 20 connecting them are arranged in parallel along the other direction. Here, the corresponding first divided beam member 20A and the first split beam member 20A and the first divided beam member 20A so as to have a beam frame 20 of an appropriate length according to the distance (L1 + L2 = W) between the columns 11 and 11 required in one direction. Select the split beam member 20B of 2.

Further, a scaffolding plate 2 constituting the floor surface of the stage is fixed between the beam frames 20 and 20 arranged in parallel in other directions. Further, the same as in the case of the temporary scaffolding, a horizontal member or a diagonal member which serves as a handrail may be provided around the scaffolding plate 2. Further, an elevating facility such as a staircase (not shown) is provided at any of the edges of the stage. With the above configuration, a stage forming a rectangular shape in a plan view can be configured. The height of the scaffolding plate 2 can be changed by adjusting the position of the fixing means 30 for fixing both ends of the beam frame 20 to the support column 11 in the vertical direction. Further, the columns 11 and 11 arranged in parallel in other directions may be connected by the same beam frame 20 as the above configuration.

The distance L3 between the columns 11 and 11 arranged in parallel in other directions can also be changed as appropriate. When the beam frame 20 is provided along the other direction, the beam frame 20 has an appropriate length that matches the distance L3 between the columns 11 and 11 in the other direction, as in the case of one direction. It can be dealt with by selecting the first split beam member 20A and the second split beam member 20B. Further, as in the case of the temporary scaffolding, the scaffolding plate 2 can be dealt with by selecting a scaffolding plate 2 having an appropriate length that matches the distance L3.

Here, in FIG. 9, one direction in which the plurality of columns 11 are arranged in parallel and the other direction are set at right angles, but this angle is not limited to a right angle, and one direction and the other direction intersect each other. If it is a direction, the angle may be other than a right angle (acute angle or obtuse angle). In this case, the plan view shape of the stage can be a shape other than a rectangle, for example, a trapezoid or a parallelogram, so that the plan view shape of the scaffolding plate 2 in this case is required to match it. .. For example, the plan view shape of the scaffolding plate 2 may be a parallelogram. Further, the number of parallel columns 11 in one direction and the number of parallel columns in the other direction can be changed as appropriate, as in the case of the temporary scaffolding.

In each of the above embodiments, the structure of the present invention has been described by taking a temporary scaffold and a temporary stage used at a construction site or the like as an example, but the structure of the present invention is not limited to the temporary scaffold or the temporary stage, for example. It can also be applied to other applications such as temporary bridges and prefabricated racks (shelf).
