Description

  The present invention relates to an attachment that is attached to a structure and supports a lifting device or a ladder, and a frame body used for the attachment.

  Conventionally, when carrying long and heavy objects such as kitchen sets into the room on the 2nd floor or higher at the stage of interior finishing during construction of a building such as a house, the interior space is narrow because it goes through the indoor stairs. The finish could be damaged. In order to avoid this, it was unloaded on the veranda and carried into the room through a large opening such as a sweeping window. Here, unloading is done by human power, and the moving contractor takes care of the outside of the building according to the method of carrying large furniture into the room, and lifts the furniture etc. to the veranda using a special rope and from the large window The work to carry in was performed by about three people.

  Recently, in order to increase the efficiency of transportation, a cart (lifter) of a lifting machine as shown in Patent Document 1 has been used, and a cart that can load a long and heavy object such as a kitchen set has been used. Yes. In this case, since a heavy object is unloaded, it is necessary to firmly fix the ladder-shaped guide rail to the handrail of the veranda and the waist wall to prevent the ladder from tipping over, but the fixing method is not particularly fixed. .

  Here, a general ladder fixing tool for carrying materials such as tiles has a column base at the tip, and this column base is placed on the roof, and is fixed to a veranda handrail or a waist wall. Not available. Therefore, Patent Document 2 discloses a guide rail for a lifting lift for mounting and installing the tip end portion of the guide rail on the veranda so that the back plate of the loading platform of the lifting lift is located at substantially the same height as the upper edge surface of the veranda. The attachment is disclosed. This attachment consists of a fixed-side mounting bracket body having a pair of arms extending in the horizontal direction, and a movable-side mounting bracket body having a fitting portion fitted to the arm section of this mounting bracket body. In the mounting bracket body on the side, a stop member for locking the tip end portion of the guide rail of the unloading lift is provided so as to be positioned below the upper edge surface of the veranda. The attachment bracket body and the movable side body are connected by the arm part across the veranda waist wall, and the fitting part slides on the arm part and the fitting part is fixed to the arm part with a set screw at a predetermined position. To do. In addition, the front end surface with an adjusting screw is brought into contact with the waist wall surface of the veranda, and the veranda waist wall is clamped and fixed like a vise.

  However, in the attachment of the above-mentioned patent document 2, when the insertion depth to the waist wall of the veranda is shallow and the load is heavy, the unloading device (elevator) is wobbled or detached from the waist wall while carrying the load. (Elevator) There is a problem that it falls over itself. In addition, structures such as the lapel walls of the veranda, handrails and headboards are exterior-finished, and at the stage of unloading heavy objects, all scaffolds used during construction have been removed. However, the surface of these structures is required not to be scratched. However, when the above-described attachment is used, the surface of the structure is damaged when the metal part of the attachment contacts the structure. There's a problem. Furthermore, in the above-mentioned attachment, it is necessary to fix by tightening with an adjusting screw in order to increase the fixing strength, and the problem that the surface of the structure is damaged becomes more remarkable. Moreover, while it is calculated | required that the surface of a structure is not damaged, it was calculated | required to improve the workability | operativity of unloading work.

  Accordingly, the present invention provides an unloading device or an attachment that supports a ladder capable of preventing the surface of a structure from being damaged and improving workability, and a frame body used for the attachment. The purpose is to do.

  Here, as a result of diligent research, the present inventors have found the characteristics of the shape of the structure to be attached with the lifting device and the attachment for the ladder. In other words, the waist wall of the veranda where such an attachment is used has a lot of irregularities due to the provision of caps and handrails at the upper end, making it difficult to secure a support surface for the attachment. We found that a flat waist wall spreads in the region, and a sufficient support surface can be secured. In view of the feature of the shape of such a structure, the following attachment has been derived.

  That is, the attachment according to the present invention is an attachment that is attached to a structure and supports a lifting device or a ladder, and the attachment is separated from the first member and the first member extending in the vertical direction in a side view. Attached to the first member at a position opposite to the second member, a second member extending in the vertical direction so as to face each other, a connecting member connecting the upper end side of the first member and the upper end side of the second member, And a support member that supports the unloading device or the ladder, and is arranged at a position on the side facing the second member at least on the lower end side of the first member, and protects the structure from the first member. A protective member and a planar second protective member disposed at a position facing the first member on at least the lower end side of the second member and protecting the structure from the second member. And butterflies.

  According to such an attachment, the first member and the second member that extend in the vertical direction and are spaced apart from each other, and the connecting member that connects the first member and the second member are provided. Therefore, from above the structure (convex structure) such as the waist wall of the veranda, a frame body having a U-shaped cross section (lower side) opened to the lower side constituted by the first member, the second member, and the connecting member The attachment can be attached to the structure in such a manner as to insert the recessed body opened into the structure. Further, since the support member is attached to the first member on the side opposite to the second member (that is, the outside of the structure), the attachment is attached to the structure and the horizontal rail or ladder of the unloading device is attached. It can be hung on a stepping bar or the like to support the unloading device and the ladder. Furthermore, since the first protective member is arranged on the side facing the second member in the first member, and the second protective member is arranged on the side facing the first member in the second member, The first protective member may be interposed between the structure and the first member, and the second protective member may be interposed between the structure and the second member. This prevents the first member or the second member from coming into direct contact with the structure at the time of attachment, and can prevent the surface of the structure from being damaged. In particular, in the attachment according to the present invention, the first protection member is disposed at least on the lower end side of the first member, and the second protection member is disposed at least on the lower end side of the second member. As described above, the structure to which the attachment is to be attached has many irregularities such as handrails and headboards on the upper end side, while the flat waist wall spreads below the headboards, providing a strong support surface. It is a structure that can be secured. Therefore, by extending the lower ends of the first member and the second member to the position of the waist wall surface, the first protection member and the second protection member can contact the structure on the wide and strong waist wall surface. That is, the attachment can be attached to the structure such that the first and second members sandwich a wide and strong waist wall via the first protective member and the second protective member. Furthermore, since the first protective member and the second protective member are planar members, the attachment can be firmly supported by the wide and strong waist wall surface. Accordingly, the attachment can be sufficiently fixed to the structure without causing positional displacement or rattling. That is, when attaching the attachment to the structure, it is possible to eliminate the need for fixing with a screw or the like, so that the surface of the structure can be prevented from being damaged. Moreover, since attachment can be performed by the operation of simply sandwiching the structure between the first member and the second member via the first protection member and the second protection member, the attachment operation can be easily performed. Moreover, when carrying in to the second floor using the indoor staircase, the attachment is configured to be lightweight and easy to carry in. As described above, the surface of the structure can be prevented from being damaged, and workability can be improved.

  In the attachment according to the present invention, it is preferable that the lengths of the first member and the second member in the vertical direction are larger than the distance between the first member and the second member. For example, when the lengths of the first member and the second member are too short, the installation position is changed from the upper end of the structure (for example, so as to roll toward the outside of the veranda) due to the load applied during the unloading operation. There is a possibility of slipping, loose fixing and rattling, or attachment coming off from the upper end of the structure and dropping off. However, the first member and the second member have a length in the vertical direction that is larger than the distance between the first member and the second member to ensure a sufficient length. Therefore, it is possible to prevent the falling off more reliably. Thereby, even if the weight of the object to be unloaded becomes heavy, the attachment can be attached to the structure without being fixed with screws or the like.

  In the attachment according to the present invention, it is preferable that the first member is longer in the vertical direction than the second member. A support member that supports the unloading device is attached to the first member. Therefore, when the unloading device is supported, the attachment acts on the attachment so that the lower end side of the first member is pressed toward the structure so that the moment rolls toward the outside of the veranda, and falls off to the support member side. Therefore, by increasing the length of the first member, it is possible to more reliably prevent the attachment from being displaced or rattling.

  Further, in the attachment according to the present invention, the structure has a waist wall and has a protruding portion protruding outward from one waist wall surface or the other waist wall surface in the thickness direction of the waist wall. One protective member is disposed between one waist wall surface of the waist wall and the first member, and the second protection member is disposed between the other waist wall surface of the waist wall and the second member, and the first protection member or The thickness of the second protective member is preferably larger than the protruding amount of the protruding portion. As a result, even if the structure has portions that protrude outward from the waist wall (such as headboards and handrails), the thickness of the protective member is larger than the protruding amount of these protruding portions. The one member or the second member and the projecting portion of the structure can prevent the exterior finish surface such as the waist wall of the veranda of the building that is the structure from being damaged without being in contact with each other.

  In the attachment according to the present invention, it is preferable that the first protective member and the second protective member are made of a cloth, a foamed resin, or rubber. By using such a material as the material of the first protection member or the second protection member, the protection member can be directly fixed to the first member or the second member. As a result, the workability of the attachment work can be improved, and the attachment can be used repeatedly without changing the protective member.

  In the attachment according to the present invention, the structure has a waist wall and has a headboard and a handrail on the upper end side of the waist wall, and the first protection member and the second protection member are mutually on the upper end side. While being connected, it is preferable to protect the headboard and the handrail from the first member, the connecting member, and the second member. As a result, the mounting surfaces of the first member, the connecting member, and the second member can all be covered with the protective member, and not only the waist wall but also the headboard and handrail can be reliably protected.

  In the attachment according to the present invention, the portion of the support member that supports the unloading device or the ladder is disposed below the upper ends of the first member and the second member, and is spaced apart from the first member in the horizontal direction. It is preferable that they are arranged. With such a configuration, it is possible to cope with the posture of the elevator when the elevator in the unloading apparatus reaches the upper end side of the guide rail and becomes an unloading state.

  In the attachment according to the present invention, it is preferable that the first member, the second member, and the connecting member are constituted by a frame having an L-shaped cross section. Thus, the weight of the entire attachment can be reduced by adopting the frame structure. Moreover, compared with the case where a board | plate material is used as a 1st member, a 2nd member, and a connection member, while being able to improve the intensity | strength of an attachment, a deformation | transformation can also be suppressed.

  In the attachment according to the present invention, the frame body and the protection member can be separated from each other, and the frame body is separated from the first member and the first member extending in the vertical direction so as to face the first member. A second member extending in the direction, a connecting member connecting the upper end side of the first member and the upper end side of the second member, and being attached to the first member at a position opposite to the second member, And a support member that supports the ladder.

  ADVANTAGE OF THE INVENTION According to this invention, while being able to prevent the surface of a structure from being damaged, workability | operativity can be improved.

It is a side view which shows the use condition of the attachment and frame body which concern on embodiment of this invention. It is a perspective view which shows the attachment and frame body which concern on embodiment of this invention. It is a side view of the attachment concerning a modification.

  Hereinafter, embodiments of an attachment and a frame body according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a side view showing a usage state of the attachment 1 and the frame body 2 according to the present embodiment. FIG. 2 is a perspective view showing the attachment 1 and the frame body 2 according to the present embodiment. In FIG. 1, cross sections of a waist wall ST 1, a coping ST 2, and a handrail ST 3 of a veranda, which are structures ST to which the attachment 1 is attached, are shown. The attachment 1 is attached to the upper edge of the structure ST and has a function of supporting the unloading device 100. In recent years, raising the floor (2nd floor or higher) kitchen components are getting bigger and weight increasing year by year, making it difficult to walk down the stairs and ensuring safety (existing buildings inside / outside / products / people). In such a case, the hand of the worker (cross tile attaching work) is stopped and the process is affected. However, the attachment 1 according to the present embodiment can cope with such a problem. Furthermore, since the attachment 1 can reduce the time for on-site delivery, it reduces the time spent on the site (parking) and responds to the reduction of neighborhood complaints and the neighborhood performance. The attachment 1 is attached so as to cover the upper edge of the structure ST from above, and protects the vicinity of the upper edge of the structure ST. Thereby, the attachment 1 can set the unloading apparatus 100 with respect to structures ST, such as a veranda, without the unloading apparatus 100 contacting directly. The left side of FIG. 1 is the outside of the veranda (outside of the building), and the right side of the page is the inside of the veranda (inside of the building).

  First, the structure ST to which the attachment 1 is attached will be described. As shown in FIG. 1, the structure ST includes a veranda wall ST1, a cap ST2 for protecting the upper end of the hip wall ST1 from rain, and a handrail ST3 provided above the cap ST2. I have. The waist wall ST1 extends vertically upward from a floor surface (not shown) on the outer edge side of the veranda. The waist wall ST1 has a waist wall surface WF1 on one side (outside the veranda) in the thickness direction of the waist wall ST1, and has a waist wall surface WF2 on the other side (inside the veranda) in the thickness direction. The waist wall surface WF1 and the waist wall surface WF2 can function as support surfaces for supporting the attachment 1, and are planes having an area and strength sufficient to function as the support surfaces.

  The outer shell part ST2 is arranged so as to cover the upper end surface of the waist wall ST1 mainly for waterproofing. The headboard ST2 includes an upper wall W1 extending horizontally along the upper end surface of the waist wall ST1, a side wall W2 that protects the upper end portion of the waist wall ST1 from the outside of the veranda, and a side wall W3 that protects the upper end portion of the waist wall ST1 from the inside of the veranda. I have. The width of the upper wall W1 of the cap wall ST2 is formed larger than that of the waist wall ST1 in the thickness direction of the waist wall ST1. Accordingly, the side wall W2 is a protruding portion that protrudes outward in the thickness direction from the waist wall surface WF1. Further, the side wall W3 is a protruding portion that protrudes outward (inside the veranda) in the thickness direction from the waist wall surface WF2. The protrusion amount of the side wall W3, that is, the distance between the outer surface of the side wall W3 and the waist wall surface WF2 is indicated by t1 as shown in FIG. Although omitted in FIG. 1, the protruding amount of the side wall W2, that is, the distance between the outer surface of the side wall W2 and the waist wall surface WF1 is also t1. The handrail ST3 extends along the upper end of the waist wall ST1 above the upper wall W1 of the coping ST2.

  Next, the unloading apparatus 100 supported by the attachment 1 and the structure ST will be described. The unloading device 100 is a device having a function of unloading heavy objects from the ground to the second and third floor verandas. With the unloading device 100, for example, a heavy object such as a kitchen counter for upper floors can be lifted and lowered. As shown in FIG. 1, the unloading apparatus 100 includes a ladder-shaped guide rail 101 and an elevator 102 that loads a heavy object and can be lifted and lowered along the guide rail 101. The unloading device 100 includes a reinforcing frame and a driving mechanism for supporting a heavy object, but only main components are shown in FIG. 1 for ease of explanation. Moreover, the structure of the unloading apparatus 100 is not specifically limited, For example, you may use the thing of a structure as shown to Unexamined-Japanese-Patent No. 6-144799.

  The guide rail 101 is a pair of long members having a U-shaped cross section extending in the vertical direction, and is fixed to each other by a plurality of horizontal members 103 extending in the horizontal direction. The elevator 102 includes a main body 104 that moves in the vertical direction along the guide rail 101, a flat plate 105 for loading heavy objects, and a flat plate 106 for leaning heavy objects. The elevator 102 is in a state where the main body 104 is rising along the guide rail 101 (this state is hereinafter referred to as “unloading state”) and a state where the main body 104 has finished climbing the guide rail 101 ( This state is hereinafter referred to as “unloading state”). In FIG. 1, the unloading state is indicated by a two-dot chain line, and the unloading state is indicated by a solid line.

  As shown in FIG. 1, the posture of the main body 104 and the flat plate 105 is the same in both the unloading state and the unloading state. In other words, the flat plate 105 maintains a horizontal spreading posture in any state. On the other hand, the flat plate 106 maintains an attitude of tilting upward so as to be parallel to the guide rail 101 in the unloaded state, and in the horizontal direction so as to form the same plane as the flat plate 105 in the unloaded state. Maintain a posture that spreads out.

  Specifically, the flat plate 106 is rotatably supported by a hinge portion 107 extending horizontally at the upper end portion of the main body portion 104 and supported by a support member 109 having a roller 108 that rolls on the outer surface 101 a of the guide rail 101. Has been. The support member 109 is vertically attached to the back side of the flat plate 106. In the unloaded state, the roller 108 rolls on the outer surface 101 a of the guide rail 101, so that the support member 109 extends outward so as to be perpendicular to the guide rail 101. As a result, the flat plate 106 is maintained in a posture parallel to the guide rail 101. On the other hand, when the unloading state is reached, the roller 108 moves from the outer surface 101a to the upper end surface 101b of the guide rail 101. Thereby, the flat plate 106 opens so as to fall around the hinge portion 107 and is maintained in a horizontal direction. As described above, when unloading the plate-shaped counter, the counter is lifted in a state of being supported so as to lean against the flat plate 106, and when the platen reaches the position of the veranda, it falls down in a horizontal state together with the flat plate 106. This facilitates unloading work on the veranda.

  The first protection member 3, the second protection member 4, and the third protection member 5 are separate from the frame body 2. The first protective member 3 and the second protective member 4 are connected by a string 31. In the use state, the string 31 passes between the third protection member 5 and the connecting member 8. Thereby, when setting the attachment 1, the position of the 1st protection member 3 and the 2nd protection member 4 can be maintained. The string 31 may pass between the caps ST2 and the handrail ST3. The first protective member 3, the second protective member 4, and the third protective member 5 are made of cloth, foamed resin, rubber, or the like that has elasticity (cushioning properties), shape following properties, and restoration properties. For example, urethane foam as a rubber-based material, such as bag cloth containing padding for curing used at construction sites of buildings, extruded polystyrene foam pieces, extruded polyethylene foam pieces, etc. used for foam insulation with foamed resin. A rubber piece or the like is used. The first protection member 3, the second protection member 4, and the third protection member 5 may be integrated with the frame body 2 in advance.

  Next, the dimensional relationship and positional relationship of the attachment 1 according to this embodiment will be described in more detail. First, the thickness of the first protective member 3 (and the distance between the waist wall surface WF1 and the first member 6) is set to be larger than the protruding amount of the portion protruding outward from the waist wall surface WF1 in the structure ST. . In addition, the thickness of the second protective member 4 (and the distance between the waist wall surface WF2 and the second member 7) is set to be larger than the protruding amount of the portion protruding outward from the waist wall surface WF2 in the structure ST. . In the present embodiment, as described above, the side walls W2 and W3 of the headboard ST2 are protruding portions, and the protruding amount is indicated by t1. Therefore, the thickness of the second protective member 4 (and the distance between the waist wall surface WF2 and the second member 7) indicated by t2 in FIG. 1 is set larger than t1. Although omitted in FIG. 1, the thickness of the first protective member 3 (and the distance between the waist wall surface WF1 and the first member 6) is also indicated by t2, and is larger than t1. As a result, a space is formed between the first member 6 and the coping ST2 without contact, and a space is formed between the second member 7 and the coping ST2 without contacting.

  In the present embodiment, the distance between the side walls W2 and W3 of the cap ST2 and the waist wall surfaces WF1 and WF2 is the protruding amount, but may be different depending on the shape of the structure ST. That is, in the structure on the upper end side of the structure ST, the distance between the portion arranged on the outermost side with respect to the waist wall surfaces WF1 and WF2 and the waist wall surfaces WF1 and WF2 corresponds to the protrusion amount. For example, when the side walls W2 and W3 of the headboard ST2 are curved toward the outside, the distance between the top of the curved shape and the waist wall surfaces WF1 and WF2 is the protruding amount. Alternatively, in the thickness direction of the waist wall ST1, when the handrail ST3 protrudes larger than the headboard ST2, or because the handrail ST3 is eccentric from the center line of the waist wall ST1, it is larger on one side than the headboard ST2. When it protrudes, the distance between the side surface of the handrail ST3 and the waist wall surface WF1 or WF2 is the protrusion amount. Further, the protruding amounts may be different from each other on the respective sides of the waist wall WF1, WF2.

  Further, the lengths of the first member 6 and the second member 7 in the vertical direction (more specifically, the length of the portion related to the attachment of the frame body 2 to the structure ST) are the same as those of the first member 6 and the second member 7. It is larger than the distance which the member 7 separates. Furthermore, the first member 6 is longer in the vertical direction than the second member 7. The length of the first member 6 involved in the attachment of the frame body 2 is the distance between the lower ends of the frames 11 and 12 of the first member 6 and the planes 17a, 18a, 19a, and 21a of the connecting member 8, and L1 Is shown (see FIG. 2). The length of the second member 7 related to the attachment of the frame body 2 is the distance between the lower ends of the frames 13 and 14 of the second member 7 and the planes 17a, 18a, 19a and 21a of the connecting member 8, and is L2. Is shown (see FIG. 2). The distance at which the first member 6 and the second member 7 are separated is the distance between the flat surfaces 11a, 12a of the first member 6 and the flat surfaces 13a, 14a, 16a of the second member 7, and is indicated by L3. (See FIG. 2). At this time, L1 and L2 are larger than L3. Furthermore, L1 becomes larger than L2.

  Further, the arrangement and size of the support member 9 are determined according to the posture of the unloading device 100 in the unloading state. Specifically, the portion of the support member 9 that supports the unloading device 100, that is, the support rod 27 is disposed below the upper ends of the first member 6 and the second member 7, and the first member 6 in the horizontal direction. It is arrange | positioned away from. Specifically, in the unloading state of the unloading device 100, the position in the vertical direction of the support member 9 is set so that the distance between the flat plate 106 and the upper end of the attachment 1 is as small as possible. As a result, the position when the heavy object is lowered from the flat plate 106 is lowered, and the workability of the unloading work is improved. Further, in the unloading state of the unloading device 100, the position of the end portion of the flat plate 106 is as close as possible to the end portion inside the veranda of the attachment 1 (that is, the position of the second member 7 in the thickness direction of the waist wall ST1). The separation distance of the support member 9 from the first member 6 is set. For example, when the end of the flat plate 106 is too close to the outside of the veranda, the flat plate 106 becomes far away during the unloading operation, and it becomes difficult to unload. On the other hand, when the end portion of the flat plate 106 is too close to the inside of the veranda, the work space of the veranda becomes narrow. Therefore, in the present embodiment, the position of the end portion of the flat plate 106 is optimized, and the workability of the unloading work is improved.

  An operation procedure for unloading a heavy object using the attachment 1 as described above will be described. First, for example, the position where the unloading device 100 is set is determined on the waist wall ST1 of the veranda on the second floor. At this time, you may cover waist wall ST1, Kasagi ST2, and handrail ST3 with a curing futon. Next, the string 31 is straddled from above the waist wall ST1, the first protection member 3 is set on the waist wall surface WF1, and the second protection member 4 is set on the waist wall surface WF2. Thereafter, the frame body 2 is placed and fitted from above the waist wall ST1 so as to sandwich the first protection member 3, the waist wall ST1, and the second protection member 4. At this time, it is confirmed that the attachment 1 does not wobble.

  After attaching the attachment 1 to the structure, the guide rail 101 of the lifting device 100 is leaned against the support rod 27 of the attachment 1, and the horizontal member 103 of the lifting device 100 is fixed by the hooks 28 and 29. Thereby, the unloading apparatus 100 and the structure ST are fixed via the attachment 1. Thereafter, work personnel for unloading work are arranged (for example, one person on the first floor and two persons on the veranda), and a heavy object is placed on the flat plate 105 of the elevator 102 on the first floor. At this time, a heavy object can be placed so as to lean against the flat plate 106 inclined obliquely upward. Next, the elevator 102 is raised along the guide rail 101 to move the heavy object to the second floor. When the elevator 102 reaches the top of the guide rail 101, the flat plate 106 opens horizontally and enters an unloading state. Along with this, the heavy object leaning on the flat plate 106 also becomes horizontal. Thereafter, the heavy load is unloaded from the elevator 102 into the veranda. Thus, since the frame body 2 inserted into the structure ST presses the protective member and the waist wall surfaces WF1 and WF2 on both sides of the waist wall ST1 are sandwiched and do not wobble, the ladder is displaced even when the heavy object is unloaded. It won't collapse (prevent ladder collapse). In addition, since the load of the lifting device 100 is not directly applied to the waist wall ST1, the coping ST2 and the handrail ST3 (made of aluminum), the guide rail 101 is applied to the support rod 27, so there is no possibility of damage to the structure ST. . Further, for example, a heavy item such as a Peninsula counter (about 90 kg) is safely carried in a short time, and then, for example, the returnable packaging is also unloaded by the elevator 102, so that the safety in the room can be ensured. Furthermore, if the attachment 1 is used, a crew member of a truck delivering materials can perform work from unloading to unloading, and the work can be performed without being affected by the operator's specialized ability, season, or climate. .

  Next, the operation and effect of the attachment 1 according to this embodiment will be described.

  The attachment 1 according to the present embodiment includes the first member 6 and the second member 7 that extend in the vertical direction and are spaced apart from each other, and the connecting member 8 that connects the first member 6 and the second member 7. ing. Therefore, the attachment 1 can be attached to the structure ST so as to cover the frame body 2 from above the waist wall ST1 of the veranda. In addition, since the support member 9 is attached to the first member 6 on the opposite side to the second member 7 (that is, the outside of the structure), the attachment 1 is attached to the structure ST and is unloaded. 100 can be supported. Further, the first protective member 3 is disposed on the side of the first member 6 facing the second member 7, and the second protective member 4 is disposed on the side of the second member 7 facing the first member 6. Therefore, at the time of attachment, the first protection member 3 is interposed between the structure ST and the first member 6, and the second protection member 4 is interposed between the structure ST and the second member 7. Can do. Thereby, it is possible to prevent the first member 6 or the second member 7 and the structure ST from coming into direct contact at the time of attachment, and it is possible to prevent the surface of the structure ST from being damaged. In particular, in the attachment 1 according to the present embodiment, the first protection member 3 is disposed at least on the lower end side of the first member 6, and the second protection member 4 is disposed on at least the lower end side of the second member 7. The structure ST to which the attachment 1 is attached has many irregularities such as handrails ST3 and Kasagi ST2 on the upper end side, and flat waist wall surfaces WF1 and WF2 spread on the lower side of Kasagi ST2 for strong support. It is the structure which can ensure a surface enough. Accordingly, by extending the lower ends of the first member 6 and the second member 7 to the positions of the waist wall surfaces WF1, WF2, the first protection member 3 and the second protection member 4 are wide and strong waist wall surfaces WF1, WF2. In contact with the structure. That is, the attachment 1 is attached to the structure by the first member 6 and the second member 7 so that the wide and strong waist wall surfaces WF1 and WF2 are sandwiched between the first protective member 3 and the second protective member 4. Can be done. Furthermore, since the first protective member 3 and the second protective member 4 are planar members, the attachment 1 can be firmly supported by the wide and strong waist wall surfaces WF1 and WF2. As a result, the attachment 1 can be sufficiently fixed to the structure ST without causing misalignment or rattling. That is, when attaching the attachment 1 to the structure ST, it is possible to eliminate the need for fixing with screws or the like, so that the surface of the structure ST can be prevented from being damaged. In addition, since the structure ST can be attached only by sandwiching the structure ST between the first member 6 and the second member 7 via the first protection member 3 and the second protection member 4, the attachment work can be easily performed. Can do. As described above, the surface of the structure can be prevented from being damaged, and workability can be improved.

  Moreover, in the attachment 1 which concerns on this embodiment, the length in the up-down direction of the 1st member 6 and the 2nd member 7 is larger than the distance which the 1st member 6 and the 2nd member 7 separate. For example, when the lengths of the first member 6 and the second member 7 are too short, the attachment 1 rolls from the upper end of the structure ST (for example, toward the outside of the veranda) due to a load related to the unloading operation. ) There is a possibility that the installation position shifts, rattles, and the attachment comes off from the upper end of the structure and falls off. However, the length of the first member 6 and the second member 7 in the vertical direction is made larger than the distance between the first member 6 and the second member 7 to ensure a sufficient length. Misalignment, rattling, and dropout can be more reliably prevented. Thereby, even if the weight of the object to be unloaded becomes heavy, the attachment 1 can be attached to the structure ST without being fixed with screws or the like.

  Further, in the attachment 1 according to the present embodiment, the first member 6 is longer in the vertical direction than the second member 7. A support member 9 that supports the unloading device 100 is attached to the first member 6. Therefore, when the unloading device 100 is supported, a moment acts on the attachment 1 in a direction in which the lower end side of the first member 6 is pressed against the structure ST. Therefore, by increasing the length of the first member 6, it is possible to more reliably prevent the displacement and backlash of the attachment 1.

  In addition, in the attachment 1 according to the present embodiment, the structure ST has a waist wall ST1, and a protruding portion (a side wall W2 of the coping ST2) projecting outward from the waist wall surfaces WF1, WF2 in the thickness direction of the waist wall ST1. , W3), the first protection member 3 is disposed between the waist wall surface WF1 of the waist wall ST1 and the first member 6, and the second protection member 4 is the second wall surface WF2 of the waist wall ST1. It arrange | positions between the members 7, and the thickness of the 1st protection member 3 and the 2nd protection member 4 is larger than the protrusion amount of a protrusion part. As a result, even if the structure ST has portions that protrude outward from the waist wall surfaces WF1 and WF2, the thickness of the protective members 3 and 4 is greater than the protruding amount of these protruding portions. Since is larger, it is possible to prevent the first member 6 and the second member 7 from coming into contact with the protruding portion of the structure ST.

  In addition, in the attachment 1 according to the present embodiment, the support rod 27 that supports the unloading device 100 in the support member 9 is disposed below the upper ends of the first member 6 and the second member 7, and is the first in the horizontal direction. The one member 6 is disposed apart from the one member 6. With such a configuration, it is possible to cope with the posture of the elevator 102 when the elevator 102 in the unloading device 100 reaches the upper end side of the guide rail 101 and enters the unloading state.

  Moreover, in the attachment 1 which concerns on this embodiment, the 1st member 6, the 2nd member 7, and the connection member 8 are comprised by the cross section L-shaped frame. Thus, the weight of the entire attachment 1 can be reduced by adopting the frame structure. Moreover, compared with the case where a board | plate material is used as the 1st member 6, the 2nd member 7, and the connection member 8, the intensity | strength of the attachment 1 can be improved and a deformation | transformation can also be suppressed.

  The present invention is not limited to the embodiment described above.

  For example, in the above-described embodiment, the first protective member and the second protective member are separated from each other, but may be integrated as a single protective member. In the example shown in FIG. 3, the first protection member 43 and the second protection member 44 are connected to each other on the upper end side via the third protection member 45. As a result, the first protection member 43, the second protection member 44, and the third protection member 45 protect the structure ST as a single protection member. As a result, the mounting surfaces of the first member 6, the connecting member 8, and the second member 7 can all be covered with the protective member, and not only the waist wall ST1 but also the headboard ST2 and handrail ST3 can be reliably protected.

  Further, in the above-described embodiment, the frame body 2 and the protection member are separated, but the protection member may be directly fixed to the frame body 2. At that time, it is preferable that the first protective member 3 and the second protective member 4 are made of cloth, foamed resin, or rubber. By using such a material as the material of the first protection member 3 or the second protection member 4, the protection member can be directly fixed to the first member 6 or the second member 7. This improves the workability of the attachment work of the attachment 1 and can be used repeatedly without changing the protective member.

  Moreover, the frame which comprises a frame body is not limited to a thing of a cross-sectional L-shape, A frame of a different shape can be used. Further, the first member, the second member, and the connecting member may be configured by combining three face materials in a U-shaped cross section instead of the frame structure. Moreover, although the unloading apparatus 100 was illustrated as an unloading work apparatus supported by an attachment, only a ladder may be sufficient.
