Mode for Carrying Out the Invention

[0009] Hereinafter, this embodiment will be described in detail with reference to the drawings. Figs. 1 to 9 are for explaining this embodiment.

Example

[0010] <Configuration> Hereinafter, the configuration of this example will be described.

[0011] Figs. 1(a) to (d) are partial perspective views of the outer wall 2 of the building 1. In this case of the figure, the outer wall 2 is composed of three outer wall materials 3 to 5. The outer wall materials 3 to 5 are, for example, of a tile-like type. Between the adjacent outer wall materials 3 to 5, they are slightly separated from each other via the joint part 6.

[0012] Reform and maintenance, for example, involve the operation of removing the middle outer wall material 4 from the outer wall 2 while leaving the outer wall materials 3 and 5 on both sides as they are among the outer wall materials 3 to 5.

[0013] The building 1 can be any type such as a detached house or an apartment house. In this example, the building 1 is a unit building. A unit building is a building 1 that can be constructed in a short period by transporting building units prefabricated in a factory to a construction site and assembling them at the construction site.

[0014] The building unit has a unit frame of a box frame structure in its skeletal part, which is formed by connecting the upper ends of four columns in a rectangular shape by four ceiling beams 26 and connecting the lower ends of the four columns in a rectangular shape by four floor beams 27. In the case of a unit building, the outer wall 2 is attached to the surface facing the outside (outdoor side) of the building unit installed at the outer peripheral part of the building 1.

[0015] The outer wall 2 is an outer wall that constitutes the outer peripheral surface of the building 1. The outer wall materials 3 to 5 are members that constitute the outer wall 2. In this embodiment, the outer wall materials 3 to 5 are arranged side by side with respect to the building 1 in a direction (vertical state) that extends long in the vertical direction 13. However, the outer wall materials 3 to 5 may be arranged vertically with respect to the building 1 in a direction (horizontal state) that extends long horizontally.

[0016] Among these, in the figure, the outer wall materials 3 and 4 are facing materials, and the outer wall material 5 is a corner material. However, the configuration of the outer wall materials 3 to 5 is not limited to this. The outer wall materials 3 to 5 are attached from the indoor side to wall fixing members such as intermediate columns installed in the outer peripheral portion of the building 1 with fixtures such as rivets.

[0017] The outer wall material 4 is removed from the side surface of the building 1 by an operation from the outside of the building 1 using the outer wall replacement jig 11 as shown in FIGS. 2(a) and 2(b). At this time, the outer wall protection jig 12 according to this embodiment is used. The outer wall protection jig 12 is a long member that protects the side edge portions 15 of the outer wall materials 3 and 5 on both sides that are close to the side edge portion 14 (of the outer wall material 4 to be removed) over substantially the entire length direction (vertical direction 13) of the side edge portion 15. In the figure, the outer wall material 5 is a facing material instead of a corner material.

[0018] The side edge portion 14 of the outer wall material 4 and the side edge portions 15 of the outer wall materials 3 and 5 are the sides (left and right sides) that are located on the left and right of the outer wall materials 3 to 5 and extend in the vertical direction 13. The side edge portions 14 and 15 are installed in parallel with a slight interval from each other to form the joint portion 6.

[0019] For the basic configuration as described above, in this embodiment, the following configuration may be provided.

[0020] (1) As shown in FIGS. 3 (to FIGS. 8), the outer wall protection jig 12 extends linearly along the side edge portions 15 of the outer wall materials 3 and 5, It is provided with a jig body 23 having an L-shaped cross section, which has an edge surface protection portion 21 for protecting the edge surface of the side edge portion 15 and a surface protection portion 22 for protecting the surfaces of the outer wall materials 3 to 5. The jig body 23 has a telescopic mechanism 25 whose length can be adjusted according to the length dimension 24 of the side edge portion 15 (or the height dimension of the outer wall materials 3 and 5, Fig. 1).

[0021] Here, the edge surface is the left and right side surfaces that form the thickness of the outer wall materials 3 and 5. Alternatively, the edge surface is the surface of the side edge portion 15 of the outer wall materials 3 and 5 that faces the thickness direction and the vertical direction 13 of the outer wall materials 3 and 5. The edge surface protection portion 21 is a portion that protects the edge surface of the outer wall materials 3 and 5, and has a uniform width that is approximately the same as or slightly narrower than the width of the edge surface (the thickness of the outer wall materials 3 and 5), and extends in the longitudinal direction of the jig body 23. The edge surface protection portion 21 is installed in a substantially abutting state against the edge surface of the outer wall materials 3 to 5.

[0022] The surface is the surface (outer surface) of the outer wall materials 3 and 5 exposed on the outside of the building 1. The surface protection portion 22 is a portion that protects the surface of the outer wall materials 3 and 5, and has a uniform width that is approximately the same as that of the edge surface protection portion 21, and extends in the longitudinal direction of the jig body 23. The surface protection portion 22 is installed in a substantially abutting state against the surface of the outer wall materials 3 and 5.

[0023] The jig body 23 is a portion that constitutes the main part of the outer wall protection jig 12, and is made of metal or resin. The jig body 23 may be fixed to the surfaces of the outer wall materials 3 and 5 on both sides with a tape 28 (Fig. 1) or the like.

[0024] The length dimension 24 of the side edge portion 15 is the distance from one end to the other end of the side edge portion 15. In this embodiment, the length dimension 24 is the distance (height dimension) from the upper end to the lower end of the outer wall materials 3 and 5. In the building 1, outer wall materials 3 to 5 of basically the same height are used for the same part of the outer wall 2.

[0025] For the outer wall materials 3 and 5, there are those with various length dimensions 24, for example, as shown in Figs. 9(a) and 9(b), and they are appropriately used separately. In the figure, 26 is the ceiling beam of the building 1, and 27 is the floor beam of the building 1. The circles in the figure are the attachment positions of the fixtures.

[0026] For example, the lower outer wall members 3 and 5 in (a) have a length dimension 24 from the lower part of the ceiling beam 26 to above the floor beam 27. The higher outer wall members 3 and 5 in (b) have a length dimension 24 from the upper part of the ceiling beam 26 to the lower part of the floor beam 27. For the outer wall members 3 and 5 having such various length dimensions 24, it is preferable that one type of outer wall protection jig 12 can be used to cope with them. For this purpose, the jig body 23 has a variable length (FIGS. 4 and 5). The length of the jig body 23 is the distance between both ends of the jig body 23 (the distance from the upper end to the lower end).

[0027] The expansion and contraction mechanism 25 is a mechanism for changing and adjusting the jig body 23 to an arbitrary length. The expansion and contraction mechanism 25 will be described later.

[0028] (2) The jig body 23 may have a gripping portion 31 (FIG. 3) at an intermediate portion in the longitudinal direction of the surface protection portion 22.

[0029] Here, the longitudinal direction is the longitudinal direction of the jig body 23 and the surface protection portion 22, and when the outer wall protection jig 12 is installed on the side edge portion 15 of the outer wall members 3 and 5, it is directed in the vertical direction 13.

[0030] The intermediate portion is the portion between both ends of the jig body 23. The intermediate portion is preferably installed at a position close to the center in the longitudinal direction of the jig body 23.

[0031] The gripping portion 31 is a handle or a holding part for gripping the jig body 23. The gripping portion 31 is integrally fixed to the surface of the surface protection portion 22 on the side opposite to the outer wall members 3 and 5 (the outside of the building 1). The gripping portion 31 has at least a parallel portion 31a that is installed substantially in parallel with a required interval (a degree that a hand or finger can enter) with respect to the surface protection portion 22, and a connecting portion 31b that connects the parallel portion 31a to the surface protection portion 22, and is thus, for example, U-shaped or L-shaped.

[0032] (3) The jig body 23 may be divided into a plurality of divided pieces 41 to 43 (FIG. 3). The adjacent divided pieces 41 to 43 may be detachably connected.

[0033] Here, the divided pieces 41 to 43 are obtained by dividing the jig body 23 into at least two pieces in the longitudinal direction, preferably three or more pieces. In this embodiment, the jig body 23 is divided into three pieces: an intermediate divided piece 41 (FIG. 6) and divided pieces 42 and 43 on both sides (or above and below) (FIGS. 7 and 8).

[0034] The intermediate divided piece 41 is the shortest. The divided pieces 42 and 43 on both sides (or above and below) are substantially the same in shape, size, and length, except that they are opposite in left-right (or up-down) orientation. The divided pieces 42 and 43 on both sides (or above and below) are arranged to abut against the intermediate divided piece 41 from below. Then, the divided pieces 41 to 43 are connected in a state where the edge surface protection parts 21 and the surface protection parts 22 are stacked vertically.

[0035] A cushion material 44 (FIG. 6) may be attached to the surface of the edge surface protection part 21 and the outer wall materials 3 and 5 of the surface protection part 22 of the intermediate divided piece 41 that abuts against them. The cushion material 44 is formed thicker than the thickness of the upper and lower divided pieces 42 and 43, and is attached to the position of the gripping part 31 so as not to interfere with the ends of the upper and lower divided pieces 42 and 43.

[0036] Similarly, a cushion material 44 (FIGS. 7 and 8) may be attached to substantially the entire area of the surfaces of the edge surface protection parts 21 and the outer wall materials 3 and 5 of the surface protection parts 22 of the upper and lower divided pieces 42 and 43 that abut against them. These cushion materials 44 soften the impact on the side edges 15 of the outer wall materials 3 and 5 when the jig body 23 is installed, protect them, and prevent damage.

[0037] And between adjacent divided pieces 41, 42 and 41, 43, an overlapping portion 45 of a required length is provided. For the divided pieces 41 to 43, the periphery of this overlapping portion 45 is a detachable connecting portion. Being detachable means that it is relatively easy to integrally couple or separately separate. The divided pieces 41 to 43 can be used separately according to the situation, or can be appropriately connected and used as shown in FIGS. 4 and 5. FIG. 4 shows a state where the divided pieces 41 to 43 are connected in three, and FIG. 5 shows a state where the divided pieces 41 and 43 are connected. Also, although not particularly shown, for example, the middle divided piece 41 can also be used alone.

[0038] (4) The expansion and contraction mechanism 25 may include a long hole 51 provided on one of the divided pieces 41 to 43, a fixing bolt 52 erected from the other of the divided pieces 41 to 43, and a wing nut 53 screwed from the tip side to the fixing bolt 52 passed through the long hole 51.

[0039] Here, the long hole 51 is provided for the divided pieces 41 to 43 that are on the upper side when stacked, for example, the middle divided piece 41 (FIG. 6). The long hole 51 is a pair of through holes respectively provided so as to extend from the vicinity of both ends to the vicinity of the gripping portion 31 of the surface protection portion 22 of the middle divided piece 41. The two long holes 51 are preferably set to a length equal to or greater than the height difference between the highest outer wall members 3 to 5 and the lowest outer wall members 3 to 5.

[0040] The fixing bolt 52 is provided for the divided pieces 41 to 43 that are on the lower side when stacked, for example, the divided pieces 42 and 43 on both sides (FIGS. 7 and 8). The fixing bolt 52 is erected substantially perpendicular to the end portion (lower end portion or upper end portion) of the surface protection portion 22 on the side of the middle divided piece 41 in the divided pieces 42 and 43 on both sides.

[0041] The wing nut 53 is a nut provided with two finger hooks so that it can be rotated by a finger. The wing nut 53 is screwed onto the fixing bolt 52 passed through the long hole 51 from the tip side of the fixing bolt 52 in a state where the intermediate split piece 41 and the upper and lower split pieces 42 and 43 are overlapped. As a result, the overlapping portion 45, which is the connecting portion between the split pieces 41 to 43, becomes the expansion and contraction mechanism 25.

[0042] Then, by sliding the fixing bolt 52 along the long hole 51 toward the end of the intermediate split piece 41, the jig body 23 becomes longer. Conversely, by sliding the fixing bolt 52 along the long hole 51 toward the center end of the intermediate split piece 41, the jig body 23 becomes shorter. The overlapping portion 45 becomes shorter when the jig body 23 is extended and longer when the jig body 23 is contracted. Note that the expansion and contraction amounts of the split pieces 42 and 43 on both sides with respect to the intermediate split piece 41 may be the same or different.

[0043] <Operation> The operation of this embodiment will be described below.

[0044] For example, when removing or replacing a part of the outer wall 2 of the building 1 during renovation or maintenance, first, as shown in Fig. 1(a), the outer wall protection jig 12 adjusts the length of the jig body 23 in advance to match the height of the outer wall materials 3 to 5. The outer wall protection jig 12 with the adjusted length places the jig body 23 in contact with the side edges 15 (and the side edge 14 of the outer wall material 4 to be removed) of the outer wall materials 3 and 5 on both sides adjacent to the outer wall material 4 to be removed. Then, the entire area of the side edges 15 of the adjacent outer wall materials 3 and 5 is physically protected from external forces, the outer wall replacement jig 11, etc. by the jig body 23. The jig body 23 is mounted using the joint portion 6 between the outer wall materials 3 to 5. Although the outer wall protection jig 12 is shown installed simultaneously on the side edges 15 of the outer wall materials 5 on both sides in the figure, the outer wall protection jig 12 may be installed sequentially on the side edge 15 on the side where the outer wall replacement jig 11 is used.

[0045] At this time, the length adjustment of the jig body 23 can be performed by the number of divided pieces 41 to 43 used and the adjustment by the expansion and contraction mechanism 25. The jig body 23 abuts and protects the edge surfaces of the side edge portions 15 of the outer wall materials 3 and 5 adjacent to each other at the edge surface protection portion 21, and at the same time, abuts and protects the surfaces of the outer wall materials 3 and 5 adjacent to each other at the surface protection portion 22.

[0046] Next, as shown in FIG. 1(b), the jig body 23 of the outer wall protection jig 12 is fixed to the surfaces of the outer wall materials 3 and 5 on both sides with the tape 28. The tapes 28 are installed in appropriate positions in a required number so as to span between the surface protection portion 22 and the surfaces of the outer wall materials 3 and 5.

[0047] Thereafter, as shown in FIG. 1(c), the outer wall replacement jig 11 is inserted from the outside of the building 1 into the joint portion 6 between the outer wall material 4 to be removed and the adjacent outer wall materials 3 and 5 (FIG. 2(a)). Then, the outer wall replacement jig 11 is reciprocally tilted up and down in a state substantially perpendicular to the joint portion 6 (moved like prying, FIG. 2(b)). Thereby, fixtures such as rivets fixing the outer wall material 4 to the building 1 and the joint portions between the fixtures and the outer wall material 4 are physically broken by the outer wall replacement jig 11.

[0048] At this time, the outer wall replacement jig 11 is moved so as not to contact the jig body 23 of the outer wall protection jig 12 as much as possible. This is repeated at the positions of the fixtures while moving in one direction, for example, from the lower side to the upper side, along the same joint portion 6, and all the fixtures are sequentially broken, so that one side edge portion 15 of the outer wall material 4 is removed from the outer wall 2 of the building 1. Thereafter, the other side edge portion 15 is also removed from the outer wall 2 of the building 1 in the same manner.

[0049] Then, as shown in FIG. 1(d), the removed outer wall material 4 is removed, and a new outer wall material is attached to the removed portion of the building 1. Note that the outer wall material 4 is supported in advance so as not to fall or drop before all the fixtures are completely removed. Thus, the renovation and maintenance of the building 1 are completed.

[0050] <Effect> According to this embodiment, the following effects can be obtained.

[0051] (Effect 1) The outer wall protection jig 12 includes a jig body 23 having an L-shaped cross-section with an edge surface protection portion 21 and a surface protection portion 22, and the jig body 23 may have a telescopic mechanism 25 whose length can be adjusted according to the length dimension 24 of the side edge portion 15 of the outer wall materials 3 and 5. For example, when removing the existing outer wall material 4 from the building 1, the jig body 23 is attached to the opposing side edge portions 15 of the outer wall materials 3 and 5 adjacent to the outer wall material 4 to be removed. Thereby, the side edge portions 15 of the adjacent outer wall materials 3 and 5 are protected by the jig body 23, and damage to the side edge portions 15 of the adjacent outer wall materials 3 and 5 can be prevented.

[0052] At this time, by making the jig body 23 have an L-shaped cross-section, the jig body 23 can protect the edge surface of the side edge portion 15 of the adjacent outer wall materials 3 and 5 with the edge surface protection portion 21 and protect the surface of the adjacent outer wall materials 3 and 5 with the surface protection portion 22. Further, by adjusting the jig body 23 to be approximately the same length as the length dimension 24 of the outer wall materials 3 and 5 using the telescopic mechanism 25, the side edge portions 15 of the adjacent outer wall materials 3 and 5 can be protected over the entire area.

[0053] (Effect 2) In the outer wall protection jig 12, the jig body 23 may have a gripping portion 31 at the intermediate portion in the longitudinal direction of the surface protection portion 22. In this way, since the jig body 23 has the gripping portion 31, the jig body 23 is easy to hold and handle. And by holding the jig body 23 at the gripping portion 31, the workability of attaching the jig body 23 to the side edge portion 15 of the adjacent outer wall materials 3 and 5 with the tape 28 can be facilitated.

[0054] (Effect 3) In the outer wall protection jig 12, the jig body 23 may be divided into a plurality of divided pieces 41 to 43, and the adjacent divided pieces 41 to 43 (specifically, the divided pieces 41, 42 and the divided pieces 41, 43) may be detachably connected. In this way, by dividing the jig body 23 into a plurality of divided pieces 41 to 43, the jig body 23 is no longer a single long member, so that the handling of the jig body 23 becomes easy, and the jig body 23 can be easily loaded and transported onto the vehicle. And by making the number of the divided pieces 41 to 43 three or more, it becomes possible to change the length of the jig body 23 according to the number of connections of the divided pieces 41 to 43.

[0055] (Effect 4) In the outer wall protection jig 12, the expansion and contraction mechanism 25 may include a long hole 51 provided in one of the split pieces 41 to 43, a fixing bolt 52 erected from the other of the split pieces 41 to 43, and a wing nut 53 screwed from the tip side onto the fixing bolt 52 passed through the long hole 51. Then, by passing the fixing bolt 52 through the long hole 51 and screwing the wing nut 53, one and the other of the split pieces 41 to 43 can be connected. In this state, by loosening the wing nut 53 and sliding the fixing bolt 52 along the long hole 51 and then tightening the wing nut 53, the jig body 23 (one and the other of the split pieces 41 to 43) can be freely expanded and contracted within the range where the long hole 51 is formed.
