Description

[Technical field]

[0001] The present invention relates to a supporting structure for an inclined structural member and a supporting method for an inclined structural member. [Background technology]

[0002] The following Patent Document 1 shows a structure in which a large roof angle member is supported by a stand. This stand is provided with a pin shoe seat that is rotatably supported on a shaft, and the inclined large roof angle member is placed on this pin shoe seat. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 115760 / 1983 Summary of the Invention [Problem to be solved by the invention]

[0004] As in Patent Document 1, in order to support an inclined structural member, it is necessary to support the load while holding the inclined structural member along the slope so that the inclined structural member does not slide down. However, with the configuration in Patent Document 1, it is difficult to support the load when there is a deviation in the slope direction, such as in the case of a shed roof.

[0005] In consideration of the above, an object of the present invention is to provide a supporting structure for an inclined structural member and a supporting method for an inclined structural member that can prevent the inclined structural member from sliding down. [Means for solving the problem]

[0006] The support structure for an inclined structural member of claim 1 comprises an inclined stand having a base plate placed horizontally on a support, legs rising from the base plate, and an inclined plate fixed to the upper ends of the legs, a holder having a stopper joined to the upper surface of a flange provided on the inclined structural member and arranged with its lower surface in contact with the inclined plate, a first holder fixed to the inclined plate, a second holder to which the stopper is engaged, and a connecting member connecting the first holder and the second holder.

[0007] In the support structure for an inclined structural member of claim 1, the inclined plate of the inclined frame placed on the shoring is placed in contact with the flange of the inclined structural member to support the inclined structural member. Therefore, the inclined structural member can be stably supported during construction without applying horizontal force to the shoring.

[0008] In addition, the first holder and the second holder fixed to the inclined plate are connected by a connecting member, and a stopper joined to the flange of the inclined structural member is engaged with the second holder, thereby preventing the inclined structural member from sliding off the inclined stand.

[0009] Furthermore, after the shoring, the inclined frame and the holder are removed, the stopper remains on the inclined structural member, but since the stopper is joined to the upper surface of the flange, it is not visible from below and is unlikely to spoil the aesthetic appearance of the inclined structural member.

[0010] The support structure for an inclined structural member of claim 2 is the support structure for an inclined structural member of claim 1, in which the first holder and the second holder are angle irons, one piece of the second holder is arranged along the flange, and the other piece and the first holder are joined by a bolt as the connecting member.

[0011] According to the support structure for a tilting structural member of claim 2, the tilting frame and the tilting structural member can be easily separated by attaching and detaching the bolts.

[0012] A supporting structure for a tilting structural member according to claim 3 is the supporting structure for a tilting structural member according to claim 1 or 2, in which the stoppers are thicker than the second holder and are provided on both sides of the second holder.

[0013] According to the support structure for the tilting structural member of claim 3, the stopper is thicker than the second holder. Therefore, even if the connection between the first holder and the second holder becomes loose, the stopper is unlikely to be released from its engagement with the second holder. In addition, since the stoppers are provided on both sides of the second holder, the tilting structural member and the tilting frame are unlikely to shift relative to each other even during an earthquake, and can be stably supported.

[0014] The method of supporting an inclined structural member of claim 4 comprises the steps of: welding a stopper to an upper surface of a flange provided on an inclined structural member that is installed at an incline with respect to a horizontal plane; welding a first holder to the inclined plate of an inclined frame having a base plate, legs rising from the base plate, and an inclined plate fixed to the upper ends of the legs; engaging a second holder to the stopper, connecting the first holder and the second holder with a connecting member, and engaging the inclined frame to the inclined structural member; and placing the base plate of the inclined frame in a state engaged with the inclined structural member on a support.

[0015] In the method for supporting a tilting structural member according to claim 4, the second holder of the tilting frame is engaged with a stopper welded to the upper surface of the flange provided on the tilting structural member. This allows the tilting frame to be engaged with the tilting structural member, so that the tilting frame can be suspended from the tilting structural member for transportation.

[0016] When the base plate of the tilt frame is placed on the support, the stopper is engaged with the second holder of the tilt frame, thereby preventing the tilt structural member from sliding off the tilt frame. Effect of the Invention

[0017] According to the present invention, it is possible to prevent the inclined structural member from slipping down. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, a support structure for an inclined structural member and a support method for an inclined structural member according to an embodiment of the present invention will be described with reference to the drawings. Components indicated by the same reference numerals in each drawing are the same components. However, unless otherwise specified in the specification, each component is not limited to one, and may be present in multiple numbers.

[0020] In addition, explanations of configurations and symbols that are duplicated in each drawing may be omitted. Note that the present disclosure is not limited to the following embodiments, and may be implemented by making appropriate modifications, such as omitting configurations, replacing them with different configurations, or combining one embodiment and various modified examples, within the scope of the purpose of the present disclosure.

[0021] <Support structure for inclined structural members> The support structure for the inclined structural member according to the embodiment of the present invention (hereinafter sometimes referred to as the "support structure") is a structure for stably supporting the inclined structural member 80 shown in FIG. 1 so as to prevent it from slipping off.

[0022] 2(A), the inclined structural member 80 is provided with an H-shaped steel 82 at its lower part. A flange 84 of the H-shaped steel 82 is supported by a support structure. The support structure is formed with the inclined frame 20, stoppers 30A, 30B, and holder 40, and is provided at multiple locations below the inclined structural member 80.

[0023] (Tilt stand) The inclined platform 20 is a structure disposed between the shoring 12 and the inclined structural member 80, and transmits the vertical load of the inclined structural member 80 to the shoring 12. The shoring 12 is a temporary support structure constructed on, for example, scaffolding 10, as shown in FIG.

[0024] The tilt stand 20 includes a base plate 22, legs 24, and a tilt plate 26, each of which is made of a steel plate.

[0025] The base plate 22 is a steel plate placed horizontally on the support 12. The legs 24 are steel plates whose lower end surfaces are fixed to the base plate and which rise up from the base plate in the vertical direction. The upper end surfaces of the legs 24 are formed at an incline with respect to the horizontal direction. The inclined plate 26 is a steel plate whose lower surface is fixed to the upper end surface of the legs 24. The inclined plate 26 is disposed at an incline with respect to the horizontal direction.

[0026] The inclined plate 26 is disposed in contact with a flange 84 of the inclined structural member 80. Here, as shown in Fig. 1, the H-shaped steel 82 forming the inclined structural member 80 does not have a constant inclination angle with respect to the horizontal plane. For example, the inclination angle of the H-shaped steel 82 on the right side of the paper in Fig. 1 is larger than the inclination angle of the H-shaped steel 82 on the left side.

[0027] 2(A) can be appropriately changed according to the inclination angle of the H-shaped steel 82. This allows the inclined plate 26 to be disposed in contact with the flange 84 of the inclined structural member 80.

[0028] The support structure of the present invention can also be applied to a case where the H-shaped steel 82 in the inclined structural member 80 is formed at a constant angle. In this case, the angle of the upper end surface of the leg portion 24 may be made constant.

[0029] (stopper) The stoppers 30A and 30B are steel plates with a thickness H1 (see FIG. 2(B)) joined to the upper surface of the flange 84 that forms the inclined structural member 80. The stoppers 30A and 30B are arranged at a distance W1 in the longitudinal direction of the flange 84. The stopper 30A is arranged at a higher position than the stopper 30B. Furthermore, as shown in FIG. 2(C), the stoppers 30A and 30B are provided on both sides of the web 86 of the H-shaped steel 82, respectively.

[0030] The stoppers 30A and 30B are welded to the flange 84 at three sides other than the sides facing each other in the longitudinal direction of the flange 84. In each drawing, a bead B is illustrated as necessary.

[0031] (holder) As shown in FIG. 2(B), the holder 40 includes an angle member 42 as a first holder, an angle member 44 as a second holder, and a bolt 46 as a connecting member.

[0032] One piece of the angle material 42 is welded to the lower surface of the tilt plate 26 of the tilt stand 20. The other piece of the angle material 42 is disposed facing downward.

[0033] The angle material 44 is a member to which the stopper 30A is locked when the tilted platform 20 is placed on the support 12. The angle material 44 is also a member to which the stopper 30B is locked when the tilted platform 20 is locked to the tilted structural member 80 and is not “placed” on the support 12, as shown in FIG. 3(C).

[0034] As shown in Fig. 2(A), the angle iron 44 is disposed along the flange 84 with one end sandwiched between the two stoppers 30A and 30B. The width W2 of the angle iron 44 is approximately 5 mm smaller than the distance W1 between the stoppers 30A and 30B. On the other hand, as shown in Fig. 2(B), the thickness H2 of the angle iron 44 is smaller than the thickness H1 of the stoppers 30A and 30B.

[0035] The other piece of the angle material 44 is disposed downward and overlaps the angle material 42. The bolt 46 connects the two overlapping angle materials 42 and 44. The angle materials 42 and 44 are connected by the bolt 46 with the tilt plate 26 of the tilt platform 20 and the flange 84 of the tilt structural member 80 sandwiched between them.

[0036] <Support method for inclined structural members> In the method for supporting an inclined structural member according to the embodiment of the present invention, first, the stoppers 30A and 30B are welded to the inclined structural member 80. Specifically, as shown in Fig. 3(A), the stoppers 30A and 30B are welded to the upper surface of the flange 84 of the H-shaped steel 82 with a gap therebetween. In addition, the angle iron 42 is welded to the inclined plate 26 of the inclined frame 20.

[0037] 3(B) and (C), the angle members 42 and 44 are connected with the bolts 46, and the angle members 44 are locked to the stoppers 30B. As a result, the tilting platform 20 is locked to the tilting structural member 80, and the tilting platform 20 can be suspended from the tilting structural member 80 for transportation.

[0038] Then, the base plate 22 of the tilting frame 20 engaged with the tilting structural member 80 is placed on the support 12 as shown by the arrow in Fig. 3(C). This causes the stopper 30A to be engaged with the angle material 44 fixed to the tilting frame 20. As a result, the tilting structural member 80 is supported by the support 12 via the tilting frame 20. In addition, the tilting structural member 80 is prevented from sliding off the tilting frame 20.

[0039] The support of the inclined structural member 80 using the inclined platform 20 and the shoring 12 is a temporary support before the inclined structural member 80 is supported by a permanent structure. After the inclined structural member 80 is supported by a permanent structure, the inclined platform 20 and the shoring 12 are removed.

[0040] <Action and Effects> In the support structure for an inclined structural member according to the embodiment of the present invention, as shown in Fig. 2(A), the inclined plate 26 of the inclined platform 20 placed on the shoring 12 is placed in contact with the flange 84 of the inclined structural member 80 to support the inclined structural member 80. Therefore, the inclined structural member 80 can be stably supported during construction without applying a horizontal force to the shoring 12.

[0041] In addition, the angle iron 42 and the angle iron 44 fixed to the inclined plate 26 are connected with a bolt 46, and the stopper 30A joined to the flange 84 of the inclined structural member 80 is engaged with the angle iron 44. This prevents the inclined structural member 80 from sliding off the inclined plate 26.

[0042] Furthermore, after the support 12, the inclined platform 20, and the holder 40 are removed, the stoppers 30A and 30B remain on the inclined structural member 80, but since the stoppers 30A and 30B are joined to the upper surface of the flange 84, they are not visible from below and are unlikely to spoil the aesthetic appearance of the inclined structural member 80.

[0043] Furthermore, with this support structure, the tilting base 20 and the tilting structural member 80 can be easily separated by attaching and detaching the bolts 46 .

[0044] 2(B), the stoppers 30A and 30B are thicker than the angle iron 44. Therefore, even if the connection between the angle iron 42 and the angle iron 44 becomes loose, the stoppers 30A and 30B are less likely to be released from their engagement with the angle iron 44.

[0045] 2(A), stoppers 30A and 30B are provided on both sides of the angle member 44, so that the tilting structural member 80 and the tilting frame 20 are unlikely to shift relative to each other even during an earthquake, and can be stably supported. Also, as shown in FIGS. 3(B) and (C), the tilting frame 20 can be stably suspended from the tilting structural member 80.

[0046] <Modification> In the above embodiment, the stoppers 30A and 30B are made of steel plates, but the present invention is not limited to this embodiment. For example, as shown in Fig. 4(A) to (C), angle members 32A and 32B or channel members (not shown) may be used instead of the stoppers 30A and 30B. By using such members, the inclined structural member 80 and the inclined frame 20 can be made even less likely to slip.

[0047] In addition, in the above embodiment, the tilting platform 20, which is engaged with the tilting structural member 80, is placed on the support 12, but the embodiment of the present invention is not limited to this. For example, after the tilting platform 20 is placed on the support 12 as shown in Fig. 5(A), the tilting structural member 80 may be engaged with the tilting platform 20 using an angle member 44 as shown in Fig. 5(B) and (C). In this way, the present invention can be embodied in various forms. [Explanation of symbols]
