Description

  The present invention relates to a panel transport jig used when transporting a panel such as a floor panel or a roof panel, and a panel transport method using the same.

  A construction method is known in which a building is constructed by transporting panels such as floor panels and roof panels manufactured in a factory to a construction site, lifting them with a crane, and installing them at predetermined positions (Patent Documents 1 and 2). reference).

  A normal floor panel has a structure having high rigidity with a peripheral edge surrounded by a frame material, and can withstand a load caused by a twist acting upon lifting.

  Patent Document 1 discloses a structure in which corners of a floor panel to which a bracket for attaching a hanging bolt for hooking a crane hook is fixed are reinforced by a connecting material.

  Furthermore, Patent Literature 2 discloses a lifting jig that can be attached with one touch to an engagement hole provided on a side end surface of a building panel. By using this lifting jig, it is not necessary to drive a wedge into the side end surface of the building panel.

JP 2000-297475 A Japanese Patent Laid-Open No. 2002-339569

  However, the load acting at the time of lifting is a temporary load. If reinforcement is performed in accordance with the load, there is a case where excessive rigidity is obtained after installation in the building. Moreover, when joining to an adjacent structure body etc., the perimeter of a panel may not be surrounded by the frame material.

  Accordingly, an object of the present invention is to provide a panel transport jig and a panel transport method capable of resisting a load that temporarily acts during transport.

  In order to achieve the above object, a transportation jig for a panel according to the present invention is a transportation jig for a panel in which a plate material is attached to the upper surface of a small beam arranged at a substantially parallel interval. The beam has a configuration in which both ends of the beam are opened, a transport beam passed in the direction orthogonal to the axis of the beam at both ends of the beam, and a plurality of the beam attached to a side surface of the transport beam. And a support metal fitting inserted into the opening of the beam.

  Here, at least one end of the transport beam may be joined to the end of the small beam via a fixing bracket. The support metal fitting may be an L-shaped metal fitting whose upper surface projects in a bowl shape.

  And the invention of the panel transport method is a panel transport method using any one of the panel transport jigs described above, wherein the support fitting attached to the side surface of the transport beam with respect to the opening of the small beam Respectively, a step of attaching the transportation jig to both side edges of the panel, a step of transporting the panel to which the transportation jig is attached to a destination, and the transportation beam at the destination. The method includes the steps of connecting a wire to lift the panel, installing the panel at a predetermined position, and removing the transportation jig after the panel is installed.

  The transport jig for the panel of the present invention configured as described above is a panel in which a panel to be transported is a plate with a plate attached to the upper surface of a small beam disposed at a substantially parallel interval. It is the structure where both ends of were opened. In other words, a panel that does not have a frame member arranged at a side edge that is oriented in a substantially orthogonal direction with respect to the small beam is an object to be transported.

  Such a panel has lower rigidity than that of the frame surrounded by the frame material on the entire periphery of the side edge. However, in the transport jig of the panel of the present invention, the transport beam is substantially perpendicular to the small beam. It functions as a frame material arranged on the directed side edge.

  For this reason, it can counter the load which acts temporarily at the time of transportation. In addition, this transportation jig is economical because it can be collected and reused after the panel is installed at a predetermined position.

  Furthermore, if at least one end of the transport beam is joined to the end of the small beam via a fixing bracket, it is possible to reliably prevent the transport jig from coming off at an unintended timing.

  In addition, if the upper surface of the support bracket protrudes in a bowl shape, the load on the panel can be supported by the bowl-shaped part inserted into the opening of the beam, and no joining work is required. It is possible to easily perform attachment and removal.

  And if it is the transportation method of the panel of this invention, a panel is temporarily reinforced at the time of transportation, and the number of members of a panel and an assembly man-hour can be reduced by collect | recovering transportation jigs after panel installation.

  The panel transported by the transport jig 20 of the present embodiment is an architectural panel such as the floor panel 1 that forms the floor surface, the roof panel or the roof panel that forms the roof surface.

  For example, the floor panel 1 is formed in a substantially rectangular shape in plan view, and is arranged to form a floor surface such as a floor ground or a floor finish surface. As shown in FIG. 2, the floor panel 1 includes floor beams 12A, 12,..., 12B as small beams arranged at intervals in parallel, and a floor plate that is a plate material attached to the upper surface thereof. 11, 11, 11 </ b> A.

  Here, the small beams forming the side edge portions on both sides of the floor panel 1 are the floor small beams 12A, 12B, and the small beams arranged between the floor small beams 12A, 12B are the floor small beams 12,. . Hereinafter, the common configuration will be described using the reference numerals of the floor beam 12.

  The floor beam 12 is formed of, for example, a hollow rectangular steel pipe having a substantially rectangular cross-sectional view. And both ends of the floor beam 12 are openings 121 and 121. The number and interval of the floor beams 12,... Used for one floor panel 1 can be arbitrarily set.

  On the other hand, the floor plates 11 and 11A are plate materials having a substantially rectangular shape in plan view that are bridged between a pair of or three or more floor beams 12 and 12. The floor boards 11 and 11A are made of hard wood cement board, plywood, etc., and the length is substantially the same as the floor beam 12 and the width is placed on one of the floor beams 12, 12A and 12B. Molded to length.

  Further, wooden bars 111 and 111A having a length equal to or shorter than the distance between the floor beams 12 and 12 can be attached to the lower surfaces of the floor plates 11 and 11A. For example, a wooden crosspiece 111 having a length approximately equal to the interval between the floor beams 12 and 12 is attached to the edge of the floor plate 11A at the right end shown in FIG. .

  Further, the wooden crosspiece 111A is opened from the end of the wooden crosspiece 111 by the width of the floor beam 12 and the wooden crosspiece 111A having a length of about the interval between the floor crossbeams 12 and 12B is attached in the direction orthogonal to the floor beam 12. It is done. In short, the wooden crosspiece 111 is accommodated between the floor beam 12 and 12, and the wooden crosspiece 111A is accommodated between the floor beam 12 and 12B.

Further, drill screws 112,... Are screwed from above the floor plates 11, 11, 11A toward the upper surfaces of the floor beams 12A, 12B, 12,.

  In the floor panel 1 manufactured in this manner, the floor beams 12A, 12,..., 12B and the floor plates 11, 11, 11A are integrated, but the floor panel 1 is oriented in the direction perpendicular to the axis of the floor beams. The frame material such as the floor beam is not arranged, and the rigidity is lower than that of the panel surrounded by the frame material on all four sides. In particular, the floor beam 12 is weak against bending in the direction perpendicular to the axis.

  Therefore, the transportation jig 20 is attached during transportation. As shown in FIG. 1, the transport jig 20 includes a transport beam 2 that is passed in the direction perpendicular to the axis of the floor beam 12 at both ends of the floor beam 12, and the side surface of the transport beam 2.

The lower surface portion 23 having a substantially L shape in cross section is formed into a substantially C shape in cross section. For the transport beam 2, C-shaped steel (grooved steel with a lip) or the like can be used.

  The length of the transport beam 2 is substantially equal to the distance between the floor beams 12A and 12B that form both side edges of the floor panel 1. The transport beam 2 has an open side directed to the opposite side of the floor beam 12 and makes the outer surface of the side surface portion 21 face the floor beam 12.

  The support fitting 3 is attached to the outer side surface of the side surface portion 21. The support metal fitting 3 is an L-shaped metal fitting having a flange 3 a that extends in a hook shape to form a support surface, and a hanging portion 3 b that contacts the outer surface of the side surface portion 21.

  The flange portion 3a of the support fitting 3 is disposed at substantially the same height as the upper surface portion 22 of the transport beam 2 and forms the upper surface. The drooping portion 3 b disposed along the outer surface of the side surface portion 21 is fixed to the side surface portion 21 by a bolt 31.

  Specifically, as shown in FIG. 1, the bolt 31 is inserted from the side of the floor beam 12 toward the support fitting 3, and a nut 32 is attached to the tip of the bolt 31 protruding to the open side of the transport beam 2.

  The plurality of support fittings 3,... Are attached to the side surfaces 21 of the transport beam 2 in accordance with the positions of the openings 121,. A fixing bracket 4 is attached to the end of the transport beam 2 on the floor beam 12A side.

  As shown in FIG. 4A, the fixing bracket 4 includes an attachment piece 4a that is brought into contact with the side surface portion 21 of the transport beam 2, and a protruding piece 4b that protrudes from the inner side edge of the attachment piece 4a toward the floor beam 12A. Thus, it is formed in a substantially L shape in plan view.

  The fixing bracket 4 is joined to the side surface portion 21 by a bolt 41 and a nut 41a. The protruding piece 4b is brought into contact with the edge 122 which is the outer surface of the floor beam 12A from the outside.

  Then, the bolt 42 is inserted from the outside toward the protruding piece 4b, and a nut 42a is attached to the tip of the bolt 42 protruding to the inner space side of the floor beam 12A. In this way, the fixture 4 is joined to the end of the floor beam 12A.

  On the other hand, as shown in FIG. 4B, the cover plate portion 5 serving as a fixing bracket attached to the end portion on the floor beam 12B side of the transport beam 2 is joined to the end portion so as to close the opening 121 of the floor beam 12B. The

  A fixing nut 51 is joined to the inner side surface of the floor beam 12B of the cover plate part 5, and the tip of the bolt 52 inserted from the open side of the transport beam 2 toward the side part 21 is Screwed into the fixing nut 51.

  In this way, both ends of the transport beam 2 are fixed to the floor panel 1 via the fixing bracket 4 and the cover plate portion 5, and the support brackets 3,... Are openings 121,.・ It will be in the state just inserted in.

  Further, by joining to one floor beam 12A by the fixing bracket 4 and joining to the other floor beam 12B by the cover plate part 5, accuracy error at the time of manufacturing the floor panel 1 is reduced. Absorption is possible.

  Next, a method for transporting the floor panel 1 using the panel transport jig 20 of the present embodiment will be described.

  First, in the factory, as shown in FIG. 2, floor beams 12A, 12,..., 12B are arranged in parallel at predetermined intervals, and an adhesive 13 is applied to each upper surface. And floor board 11,11,11A to which wooden crosspiece 111,111A was attached as needed is installed on floor beam 12A, 12, ..., 12B.

  Drill screws 112,... Are screwed into positions overlapping the peripheral edges of the floor plates 11, 11, 11A and the floor beams 12A, 12,. The openings 121 and 121 at both ends of the floor beam 12B are closed by the cover plate portions 5 and 5 at this time.

  Subsequently, as shown in FIG. 1, the transportation jigs 20 and 20 are attached to both side edges of the floor panel 1. .. Are fixed to the side surface 21 of the transport beam 2 by bolts 31 and nuts 32 in accordance with the positions of the openings 121... Of the floor beams 12.

  Further, the fixing bracket 4 is fixed to the end of the transport beam 2 facing the floor beam 12A by a bolt 41 and a nut 41a. The transport jig 20 assembled in this manner is directed in the direction orthogonal to the axis of the floor beam 12 so that the opening 121 of the floor beam 12 faces the support fitting 3 side.

  And the support metal fittings 3 ... of the transport jig 20 are inserted in the openings 121, ... of the floor beams 12, ..., respectively. Moreover, with respect to the cover plate part 5, one end of the transport jig 20 is fixed to the floor beam 12B by screwing a bolt 52 from the open side of the transport beam 2.

  Furthermore, the other end of the transport jig 20 is fixed to the floor by joining the fixing bracket 4 having the protruding piece 4b in contact with the edge 122 of the floor beam 12A to the floor beam 12A with a bolt 42 and a nut 42a. Fix to the beam 12A.

  The transport beam 2 can be firmly attached by joining the floor beam 12B via the cover plate portion 5. In addition, by joining the floor beam 12A via the fixing bracket 4, the manufacturing error of the floor panel 1 can be absorbed and the transport beam 2 can be attached.

  Further, a suspension bolt 25 is attached to the long hole 24 (see FIG. 4A) of the upper surface portion 22 of the transport beam 2 as shown in FIG. The floor panel 1 whose side edges are reinforced by the transportation jigs 20 and 20 has a structure capable of withstanding a load that temporarily acts during transportation.

  For example, when the floor panel 1 is lifted by hooking the suspension bolts 25, 25, a load such as torsion that does not act at the time of installation may occur on the floor panel 1, but by attaching the transportation jigs 20, 20, Deflection when the floor panel 1 is lifted can be reduced to prevent deformation and damage.

  The floor panel 1 to which the transportation jigs 20 and 20 are attached is loaded from a factory onto a truck and transported to a construction site as a destination. And at a construction site, a hook is hung on the suspension bolts 25,... Attached near the both ends of the transport beams 2 and 2, and is lifted by a crane.

  FIG. 5 illustrates the lower floor unit 6 which is a predetermined position where the floor panel 1 is installed. The lower unit 6 has a frame structure formed of pillar members 61,... Arranged at four corners, and beam members 62A, 62B spanned between upper ends of the pillar members 61,.

  The floor panel 1 lifted by the crane moves in the air without causing a large deflection and is installed on the upper surface of the lower floor unit 6. After confirming that the floor panel 1 is installed in a stable state, the transportation jigs 20 and 20 are removed.

  As shown in FIG. 4A, the transport jig 20 can release the joint via the fixture 4 by loosening the nut 42 a and removing the bolt 42. Moreover, as shown to FIG. 4B, joining via the cover board part 5 can be cancelled | released by loosening and removing the volt | bolt 52. FIG.

  And after removing the transport jigs 20 and 20, as shown in FIG. 6, each floor beam 12,... Is a beam which is an adjacent structure using a fixing bolt set 14,. It joins to material 62B, 62B. As described above, when the floor beams 12 are fixed to the beam members 62B and 62B directed in the direction perpendicular to the axis, the floor panel 1 has rigidity equivalent to that surrounded by the frame material on all sides. To prepare.

  Next, the operation of the panel transport jig 20 of this embodiment and the method of transporting the floor panel 1 using the same will be described.

  The panel transportation jig 20 of the present embodiment configured as described above has the floor beams 1A, 12,..., 12B on which the floor panels 1 to be transported are arranged substantially in parallel at intervals. This is a panel in which floor plates 11, 11, and 11A are attached to the upper surface.

  Then, both ends of the floor beam 12 are not blocked by a beam material or the like, and remain in the openings 121 and 121. In other words, the floor panel 1 having a simple configuration in which there is no frame member disposed on the side edge directed in the substantially orthogonal direction with respect to the floor beam 12 is a transport target.

  Such a floor panel 1 is less rigid than the one surrounded by the frame material on the entire periphery of the side edge, but by attaching the transportation jigs 20 and 20 of the panel of the present embodiment, The frame material oriented in a direction substantially orthogonal to the floor beam 12 is a highly rigid panel arranged on the side edge.

  For this reason, it is possible to counter a load such as a twist that temporarily acts during transportation. Moreover, since this transportation jig | tool 20 can be collect | recovered and reused after installing the floor panel 1 in a predetermined position, it is economical.

  Furthermore, if the end portion of the transport beam 2 is joined to the end portions of the floor beams 12A and 12B via the fixing bracket 4 and the cover plate portion 5, the transport jig 20 is detached at an unintended timing. Can be surely prevented.

  In addition, if the upper surface of the support bracket 3 is a flange portion 3a in which a support surface is formed by extending in a bowl shape, the flanges inserted into the openings 121,. The panel load can be distributed and supported by the portions 3a,.

  In addition, the support brackets 3,... That do not need to be joined only by being inserted into the openings 121,... ing.

  Further, if the floor panel 1 is temporarily reinforced during transportation, and the transportation jigs 20 and 20 are collected and reused after the floor panel 1 is installed at a predetermined position, the number of members and the assembly of the floor panel 1 Man-hours can be reduced.

  The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes that do not depart from the gist of the present invention are not limited to this embodiment. Included in the invention.

  For example, in the above-described embodiment, the floor panel 1 is described as an example of a panel, but the present invention is not limited to this. For example, the panel transportation jig of the present embodiment can be applied to building panels such as roof panels and various panels.

  Moreover, although the said embodiment demonstrated the method of attaching the transport jigs 20 and 20 after manufacturing the floor panel 1, it is not limited to this. For example, the support brackets 3,... Are attached to the transport beam 2 in advance, and the floor beams 1 are arranged in accordance with the positions of the support brackets 3,. If it is a method, it will become easy to position the floor beams 12,.

  Furthermore, in the said embodiment, although the edge part of the transport beam 2 was joined with the floor panel 1 via the fixing metal fitting 4 and the cover board part 5, it is not limited to this, It attaches to the transport jig 20 All the metal fittings to be used may be configured to be inserted into the openings 121 of the floor beam 12 like the support metal fittings 3.
