Description

[Technical Field]

[0001] The present invention relates to a temporary shed (hereinafter referred to as a "temporary shed") that is installed on a station platform or the like. [Background technology]

[0002] A covered structure installed on a platform to protect passengers from getting wet in the rain or snow is called a shed or roof (see Patent Document 1 and Non-Patent Document 1). Due to the aging of this shed and its lack of earthquake resistance, when carrying out repair work, rebuilding work, reinforcement work or other construction work, it is necessary to construct a temporary shed inside the existing shed to ensure the safety of passengers getting on and off. For this temporary shed, members for constructing temporary scaffolding (hereinafter simply referred to as "scaffolding members") as shown in Non-Patent Document 2 may be used as a framework.

[0004] [Non-Patent Document 1] "Seismic reinforcement of rail-construction platform roofs for conventional lines" https: / / jr-central.co.jp / news / release / _pdf / 000043224.pdf [Non-patent document 2] "ND System Darwin" https: / / www.nrg.co.jp / nikkenlease / handling / kensetsu?detail=3411 Summary of the Invention [Problem to be solved by the invention]

[0005] However, when using scaffolding members for temporary houses, there is still room for improvement in the following respects. (1) Scaffolding components can only be installed within the span specified for temporary scaffolding. Therefore, the width of the platform (opening width) is limited by the span of the beams installed on the left and right sides of the temporary shed. (2) Depending on the span of the support pillars installed in the longitudinal direction of the temporary shed, there is a risk that the support pillars may be located in front of the boarding and alighting doors of trains stopping at the platform. (3) The pillars intended for use as temporary scaffolding have flanges along their longitudinal direction for attaching connecting members and handrail materials. Therefore, it was necessary to protect the pillars so that these flanges would not get in the way of passengers getting on and off the platform.

[0006] Therefore, an object of the present invention is to provide a temporary house that is more convenient. [Means for solving the problem]

[0007] The present invention, which has been made to solve the above-mentioned problems, is a temporary shed to be installed on a platform of a railway station, and comprises at least a plurality of portal frames installed at intervals along the longitudinal direction of the platform, the portal frames having at least a set of pillars erected at intervals along the width of the platform, brackets that are detachable from the pillars, and beams connecting the brackets, the pillars having at least a connectable portion provided at a predetermined position in the longitudinal direction of the pillars, the brackets having at least a connecting portion connectable to the connectable portion and an attachment portion to which the beams can be attached, and the connection position of the beams with the attachment portion is configured to be movable in the longitudinal direction of the beams. In addition, the present invention may be configured so that the beam material comprises a frame-shaped member having an upper chord member and a lower chord member, the mounting portion has at least an upper chord side mounting fixture capable of mounting the upper chord member and a lower chord side mounting fixture capable of mounting the lower chord member, the upper chord side mounting fixture being a hook-shaped member, and the lower chord side mounting fixture being a clamp-shaped member. In addition, the present invention may be configured so that the support pillars have at least a lower support pillar and an upper support pillar, each of which has a connected portion, and among the connecting portions provided on the bracket, the connecting portion corresponding to the connected portion at the top of the upper support pillar is of a wedge tightening type, and the connecting portions corresponding to the remaining connected portions are of an insert type. Furthermore, the present invention may be configured so that it further includes a hoisting device capable of suspending the beam from an existing structure on the platform, and the lower support is removed from the support that is the object for attaching and detaching the bracket that is the object for attaching the beam suspended by the hoisting device. In addition, the present invention may be configured such that the support pillar does not have any protrusions on its outer periphery below the connected portion. [Effects of the Invention]

[0008] According to the present invention, at least one of the following effects can be achieved. (1) The beams can be attached to the posts and brackets at any point along the length of the beams, so the opening width of the temporary shed can be freely set. (2) When attaching a beam between posts, the upper chord side fixture, which is made of a hook-shaped member, is first engaged with the upper chord and temporarily placed in place, allowing the connection position between the post and the beam to be adjusted. Then, by fastening the lower chord side fixture, which is made of a clamp-shaped member, to the lower chord, the beam can be fixed in place relative to the post while preventing it from falling or collapsing. (3) By providing a hanging device that can hang beams, it is possible to avoid the risk of the boarding and alighting doors of trains stopping at the platform interfering with the support pillars. (4) By not providing any protrusions on the outer periphery of the support pillar below the connected part, the burden of protective work to ensure that it does not interfere with passengers getting on and off the platform is reduced.

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. [Example]

[0011] <1> Overall configuration (Fig. 1) The temporary shed according to this embodiment is a temporary structure installed on a platform of a railway station. Figure 1 shows the overall configuration of a temporary shed to be installed inside an existing shed (not shown) installed on a railway station platform. The X direction shown in FIG. 1 indicates the longitudinal direction of the platform, and the Y direction indicates the width direction of the platform. The temporary shed of the present invention comprises at least a plurality of portal frames A1 installed at intervals in the longitudinal direction of the platform (X direction in Figure 1), and further comprises connecting members A2 connecting the portal frames A1 together, roofing materials A3 constituting the roof portion of the temporary shed, and the like.

[0012] <1.1> Connecting material (Fig. 1) The connecting member A2 according to the present invention is a member that connects the portal frames A1 together. In the present invention, the number, shape, structure, arrangement, etc. of the connecting material A2 are not particularly limited. In this embodiment, it has a connecting material A2 (shown in Figure 1) that connects the beam members 33 of the beam member 30 described later, and a connecting material (not shown in Figure 1) that connects the connected portions 11 (11b) provided on the upper support pillars described later.

[0013] <1.2> Roofing materials (Figure 1) The roof material A3 according to the present invention is a member that connects the portal frames A1 together and constitutes the roof portion of the temporary shed. In the present invention, the number, shape, structure, arrangement, etc. of the roofing material A3 are not particularly limited. In this embodiment, scaffolding boards that make up temporary scaffolding are used as roofing material A3, and the roof portion of the temporary shed is constructed by engaging multiple roofing materials A3 between the upper chord members 31 of the beam members 30 described below.

[0014] <1.3> Gate-type frame (Fig. 1) The portal frame A1 according to the present invention is a member that constitutes the framework of the temporary shed. In the present invention, the number, shape, structure, arrangement, etc. of the portal frames A1 are not particularly limited. In this embodiment, the portal frame A1 is configured to include at least a set of pillars 10, brackets 20 attached to each pillar 10, and beams 30 connecting the pillars 10 via the brackets 20 attached to each pillar 10. Each part of the portal frame A1 will be described in detail below.

[0015] <2> Supports (Figures 1 and 2) The support pillars 10 are members located on both sides of the portal frame A1 and function as pillar portions that support the beams 30, the roof material A3, the connecting materials A2, and the like. In the present invention, two support pillars 10 installed at an interval in the width direction of the platform (Y direction in FIG. 1) are defined as a set of support pillars 10 that constitute the portal frame A1. In the present invention, the support 10 may be a newly designed dedicated product, or a publicly known support 10 member used in temporary scaffolding may be used. In this embodiment, the support pillar 10 is configured to be divided into upper and lower pillars, and includes a lower support pillar 10A that is erected on platform B and an upper support pillar 10B that is connected to the top of the lower support pillar 10A.

[0016] <2.1> Connected part (Fig. 1, Fig. 2) At a predetermined position in the longitudinal direction of the support 10, a mounting portion 11 for connecting a connecting material A2 or a bracket 20 is provided. In the present invention, the number, shape, structure, and connecting mechanism between the connecting portion 21 and the connected portion 11 relative to the support 10 are not particularly limited. In this embodiment, as shown in FIG. 1, one connected portion 11 (11a) is provided on the lower support 10A, and two connected portions 11 (11b, 11c) are provided on the upper support 10B. Each of the connected parts 11 is composed of a disk-shaped member that is cross-shaped when viewed from above, and at the points extending in the cross direction, it has through holes 111 into which the connecting parts 21 provided on the brackets 20 described later, or connecting material A2 (not shown in Figure 1) that connects the posts, can be inserted.

[0017] <2.2> Jack base (Fig. 2) A jack base 12 may be provided at the lower end of the support pillar 10 in the present invention. This jack base 12 allows the height of each support pillar 10 to be adjusted to accommodate the slope or unevenness of platform B. 2 has a base part 121 that contacts the installation surface, a screw shaft 122 that stands upright from the base part 121, and a rotating body 123 that can be moved by rotating on the screw shaft 122, and is configured to have a detachable handle (not shown) for rotating the rotating body 123. This is because if the handle remains fixed to the rotating body 123, there is a risk that people moving around the platform (such as passengers, employees, or workers) may get their feet caught in the handle and fall.

[0018] <2.3> Eliminating obstacles to pedestrians It is preferable that the support 10 of the present invention be configured so that, except for the connected portion 11 provided at a predetermined position in the longitudinal direction of the support 10, no protrusions are provided on the outer circumferential portion below the connected portion 11. This configuration is expected to prevent injuries caused by contact between the protrusions and people on the platform (passengers, employees, workers, etc.), and to reduce the burden of protective work to ensure that they do not get in the way of passengers. In this embodiment, as shown in FIG. 2, the lower support 10A is configured so that no protrusions are provided on the outer periphery below the connected portion 11 (11a) provided on the lower support 10A.

[0019] <3> Beam material (Figure 1) The beam 30 is a member for connecting a pair of supports 10 together. In the present invention, the shape and structure of the beam 30 are not particularly limited, and members of any shape, such as a rod shape or a frame shape (including an approximately truss shape or an approximately ladder shape), can be used. Furthermore, the beam material 30 in the present invention may be a newly designed product, or may be a known beam frame or the like used in temporary scaffolding. In this embodiment, the beam 30 is a substantially ladder-shaped frame member having at least an upper chord 31, a lower chord 32, and a beam 33. As shown in FIG. 1, the bundle 33 is provided with a disk-shaped flange for connecting the end of the connecting material A2.

[0020] <4> Bracket (Fig. 3, Fig. 4) The bracket 20 is a member that is interposed between the support 10 and the beam 30 to fix them in a predetermined positional relationship. The bracket 20 according to the present invention is provided with a mechanism (connecting portion 21) for connecting to the support 10 and a mechanism (mounting portion 22) for attaching a connecting portion to the bracket 20.

[0021] <4.1> Connection part (Fig. 3) The connecting portion 21 is a portion for connecting the bracket 20 to the support 10. In the present invention, the shape and structure of the connecting portion 21 are not particularly limited, as long as it has a shape and structure corresponding to the connected portion 11 provided on the support 10 described above. In this embodiment, as shown in Figures 3 and 4, the bracket 20 has three connecting portions 21 (21a, 21b, 21c), of which the uppermost connecting portion 21 (21b) uses a wedge tightening type connecting mechanism for the connected portion 11 (11b), and the remaining connecting portions 21 (21a, 21c) use an insertion type into through holes 111 provided in the connected portions 11 (11a, 11c).

[0022] In the present invention, although it is possible to make all of the connecting parts 21 wedge-tight, as in this embodiment, if only the top connecting part 21 (21b) is made wedge-tight, the convenience of the attachment and detachment operations is further improved.

[0023] <4.2> Mounting part (Fig. 4) The mounting portion 22 is a portion for mounting the beam material 30 to the bracket 20 . In the present invention, the shape, structure, and number of the attachment portions 22 are not particularly limited. In this embodiment, as shown in Figure 4, the mounting portion 22 is made up of two mounting fixtures (upper chord side mounting fixture 221 and lower chord side mounting fixture 222) spaced apart above and below the bracket 20 so as to correspond to the upper chord member 31 and lower chord member 32 that make up the beam member 30, and these mounting portions 22 are provided on opposite surfaces of the square pillars that make up the main body of the bracket 20. The bracket 20 can be made common to a set of pillars that make up the portal frame A1.

[0024] <4.2.1> Upper chord side fixture (Fig. 4) The upper chord side mounting fixture 221 is a part for mounting the upper chord member 31 that constitutes the beam member 30. In the present invention, the shape, structure, and number of the upper chord side mounting fixture 221 are not particularly limited, but it is more preferable that the upper chord member 31 be capable of longitudinal movement even after the upper chord member 31 has been attached. In this embodiment, the upper chord side mounting fixture 221 is a hook-shaped member with the receiving port for the upper chord member 31 facing upward. According to this configuration, when fixing the beam 30 to the bracket 20, there is no need to precisely adjust the positional relationship between the bracket 20 and the upper chord 31; the beam 30 can be temporarily fixed to the bracket 20 simply by first engaging the upper chord 31 with the upper chord side mounting fixture 221.

[0025] <4.2.2> Lower chord side mounting fixture (Fig. 4) The lower chord side mounting fixture 222 is a part for mounting the lower chord member 32 that constitutes the beam member 30. In the present invention, the shape, structure, and number of the lower chord side mounting fixtures 222 are not particularly limited. In this embodiment, the lower chord side mounting fixture 222 is a clamp-like member capable of gripping the lower chord member 32. According to this configuration, when attempting to fix the beam 30 to the bracket 20, the upper chord 31 is first engaged with the upper chord side mounting fixture 221 to temporarily fix the beam 30, and then the lower chord 32 is grasped with a clamp-like member, thereby allowing the beam 30 to be fixed to the bracket 20 without the risk of the beam 30 falling, etc.

[0026] <4.2.3> Other aspects In the present invention, for example, an embodiment in which the upper chord side mounting fixture 221 is a clamp-shaped member and the lower chord side mounting fixture 222 is a hook-shaped member may not be preferable from an operational standpoint. This is because when attempting to fix the beam 30 to the bracket 20, if the lower chord 32 is engaged with the lower chord side fixture 222 and the upper chord 31 is not fixed with the upper chord side fixture 221, there is a risk of the beam 30 collapsing around the lower chord 32 as its axis of rotation, resulting in a risk of accidental contact between the beam 30 and a worker.

[0027] <5> Summary (Figure 1) According to the temporary shed of this embodiment, the upper chord member 31 can be engaged with the upper chord side mounting fixture 221 at any longitudinal location, so the distance between the pillars 10 (opening width as temporary shed A) can be set to any length. [Example]

[0028] <1> Overall configuration (Fig. 5, Fig. 6) The temporary shed according to the present invention can also be configured to have a hoisting device 40 that can suspend the beam 30 from an existing structure on the platform. For example, as shown in Figure 5, depending on the length of the connecting material A2 connecting the gate-shaped frames A1 in the longitudinal direction of platform B, it is possible that the support pillar 10 (lower support pillar 10A in Figure 5) will overlap the position of the boarding and alighting door C of a train stopping at platform B. In this case, as shown in Figure 6, one possible method is to use mooring parts 34 provided on both ends of beam 30, which is connected to the interfering support pillar 10 via brackets 20, as the suspension point, and attach a suspension device 40 that takes up the reaction force from an existing structure (such as an existing shed) on platform B, and then transfer the weight of beam 30 to this suspension device 40, and then remove only the lower support pillar 10A. In this case, if a plug-in type is used for the lowest connecting portion 21 provided on the bracket 20 instead of a wedge fastening type, the removal of the lower support 10A becomes easier since there is no need to release the wedge fastening.

[0029] <2> summary According to this configuration, the number of support columns that make up the portal frame can be reduced as needed. [Example]

[0030] A structure employing the temporary shed structure of the present invention can also be used for the following purposes, for example. (Example 1) Temporary passageways constructed around or within stations In this example, it is possible to obtain effects such as increasing the degree of freedom in the opening width of the temporary passageway and reducing the obstruction to people passing through the passageway.
