Description

  The present invention relates to a construction method that can easily construct a wooden building close to a boundary with an adjacent land, and more particularly, to a construction method that can construct a wooden building skillfully even in a narrow land blocked on three sides.

  As for the erection method for constructing a wooden building in the vicinity of the boundary with the adjacent land, the methods described in Patent Documents 1 to 6 are known. Here, in Patent Document 1, after constructing two rows of left and right outer walls in the depth direction from the frontage side, the left and right outer walls are moved toward a target position based on a work scaffold located between the left and right outer walls. The construction method is described.

  In this invention, the outer wall upper part is moved outward and inclined with the outer wall lower part as a fulcrum, and then returned to the vertical posture by moving the outer wall lower part, and by repeating this alternate operation, the left and right direction of the outer wall is repeated. The move to is completed.

  However, the above moving method not only lacks smooth movement, but, for example, when a through pillar cannot be used as in a three-story house, the outer wall surface is inclined at the timing when the outer wall is inclined. There is a high possibility that cracks will occur, and if cracks occur, there will be a problem that the precious outer walls will be spoiled.

  On the other hand, in Patent Documents 2 to 6, a method of constructing a pair of left and right outer walls on a carriage on which rollers are arranged, making one outer wall a fixed state, and using this as a reaction force to move the other outer wall Is adopted.

  However, this construction method has a problem that the construction work of the central part of the building constituting the inside of the outer wall is extremely difficult, particularly in a narrow area where three sides are closed. In other words, in such a narrow area, after fixing the left and right outer walls at the target position, there is no choice but to configure the center of the building from the innermost part to the frontage part. The work platform must be disassembled and removed to the frontage side, which is very difficult. In addition, even after the innermost building work, the building work must be repeated while moving the work scaffold to the frontage side, which is also complicated in this sense. This problem of complexity is exactly the same in the case of the invention of the cited document 1.

  Furthermore, since it is necessary for the inventions of Patent Documents 2 to 6 to maintain one side of the outer wall before moving arranged on the carriage in a fixed state on the carriage, the outer wall and the base on one side During this period, it is necessary to fix and place the temporary braces with a special structure, which not only increases the work load of the attachment and detachment work, but also increases the construction cost by the amount of the special structure temporary braces. .

  In addition, in the inventions of Patent Documents 2 to 6, in order to horizontally move the outer wall on the other side using the outer wall on the one side in a fixed state as a reaction force body, a long elongated member called a staggered beam is required. The work becomes difficult by the length. Moreover, in order to move the outer wall, it is necessary to arrange a large number of elongated members at various locations on the outer wall, and it is not easy to maintain the optimum position while extending the tip of the elongated member. There is a risk that a part of the outer wall is subjected to local stress during the extension work.

  In order to avoid the above problem, it is possible to provide a dedicated reaction force body (reaction wall) close to the inside of the temporarily installed outer wall, but the reaction wall has a height corresponding to the outer wall. Therefore, a large amount of extra costs are required for installation and removal.

  In addition, after moving the outer wall to the target position, it is necessary to lower the outer wall on the foundation after removing unnecessary parts such as the carriage, but there is enough work space for removing the carriage etc. In order to ensure, the higher the rise amount of the outer wall, the higher the possibility that local stress will be applied to the left and right outer walls at the time of the rise and the subsequent fall. In consideration of the possibility of the outer wall falling down, the outer wall restraint cannot be relaxed.

  When local stress of a level that cannot be ignored occurs during the horizontal movement of the outer wall (extension of the extension member) or the vertical movement of the outer wall (up / down), especially when a through pillar is used as in a three-story house. If it cannot be used, the outer wall will be cracked, and if such an accident occurs, the outer wall will be spoiled.

  The present invention has been made in view of the above-described problems, and can smoothly proceed with construction work even in a narrow area where three sides are closed, and even on an outer wall where a through pillar cannot be used. It is an object of the present invention to provide a erection method that can finish construction work at low cost without using stress and using a special member.

  In order to achieve the above object, the erection method according to the present invention completes the foundation of a wooden building and then completes the center of the building except for the outermost part of the building that reaches the left and right outer walls as seen from the frontage. Corresponding to the construction of the central part process and the construction of the central part of the building, the guide rail is arranged on the base to the target position where the outer wall should be constructed, and the left and right outer walls are placed on the guide rail via the carriage. The outer wall process to be completed, the preparation process of bridging a plurality of link members that can be extended in the horizontal direction between the central part of the building and the outer wall, and the plurality of link members are integrally extended, thereby extending the outer wall to the center of the building. A horizontal movement step for moving the outer wall to the target position apart from the part, a vertical movement step for moving the outer wall that has reached the target position upward, removing the rails and carriages, and then lowering on the foundation, and a link member Remove the left and right outside And the left and right base ends of the link members are arranged in the depth direction, with column members located at the outermost part of the center of the building and column members constituting the outer wall. It is held by a penetrating shaft member.

  In the present invention, since the center of the building is completed first, after the outer wall is moved to the target position, it is only necessary to construct the outermost part of the building between the center of the building and the outer wall. Even on the ground, there is no difficulty in work as in the conventional method. In other words, in the final process, it is only necessary to place a horizontal member between the center of the building and the outer wall and to lay the floor, etc., and the floor is already laid on each floor of the center of the building. There is no particular need for a work platform, and a low-cost and high-efficiency construction method is realized with no waste.

  Moreover, in this invention, since it transfers to a preparation process and a horizontal movement process in the state which the building center part was completed, it is not necessary to reinforce a building center part by the temporary brace etc. of a special structure like the conventional construction method. Also, in the horizontal movement process, the link member spanned between the center of the building and the outer wall is extended, so a relatively small and light link member is sufficient, and preparation work and horizontal movement work are easy. Accurate horizontal movement is possible as long as the overall length is short.

  Further, in the present invention, the left and right base ends of the link member are held by the shaft member that penetrates the left and right column members standing facing each other in the depth direction. Can be swung. Therefore, even when the amount of rise and fall in the up and down movement process is large, the occurrence of local stress can be prevented by moving the appropriate position of the link member including the mechanical backlash part. Therefore, even when the through pillar cannot be used in the outer wall, the outer wall is not cracked.

  In the present invention, preferably, an auxiliary pillar is fixed inside the pillar material constituting the outer wall, the lower end of the auxiliary pillar is pressed to raise the outer wall, and the lower end of the auxiliary pillar is lowered to lower the outer wall. Is placed on the foundation. If such a structure is taken, the up-and-down movement process can be realized smoothly.

  Moreover, it is preferable that this additional column is fixed by connecting an upper tube column and a lower tube column that are continuous through a horizontal member. By adopting such a configuration, for example, local stress can be effectively prevented even when a through pillar is not used for the outer wall.

  The link member according to the present invention includes a movable main body configured to be able to artificially change the distance between the contact plates disposed at both ends, and swing arms disposed at both ends of the movable main body. Each of the swing arms includes a penetrating portion penetrating the cylindrical body fixed to the movable main body portion, a connecting portion fixed to both ends of the penetrating portion, and a connecting portion connecting the base ends of the two connecting portions to each other And the connecting portion is arranged so as to function as a shaft member penetrating in the depth direction each of the pillar material located at the outermost part of the center of the building and the pillar material constituting the outer wall. Is preferred.

  In this case, since a general-purpose part such as a pipe support can be used as the movable main body portion, it is very effective in reducing the construction cost.

  It is preferable that the rotation of the penetrating portion of the swing arm is configured to be regulated at the position of the cylindrical body. In this case, the link member in which the rotation of the penetrating portion is restricted functions like a brace when the outer wall moves up and down, so that the outer wall can be effectively prevented from falling down.

  Here, when the vertical movement amount is relatively small, not only the horizontal movement process but also the vertical movement process is preferably executed in a state where the movable main body and the swing arm are integrated. . On the other hand, when a large amount of vertical movement is desired, in the vertical movement process, it is preferable that both or one of the swing arms is configured to be swingable with respect to the movable main body.

  According to the present invention described above, the construction work can proceed smoothly even in a narrow area where three sides are closed, and there is no local stress even on the outer wall where a through pillar cannot be used, and a special member is used. Construction work can be completed at low cost without any problems.

  Hereinafter, examples will be described in more detail. FIG. 1 is a plan view showing a state in which a building center part 1 is completed in a narrow area where three sides including the innermost part are closed, and outer walls WAL are temporarily installed on the left and right sides thereof. That is, FIG. 1 finished the center part process which completes the building center part 1, and the outer wall process which temporarily installs the outer wall WAL in the state hold | maintained at the building center part 1 with the link member LINK (FIG. 5). The state is illustrated, and the building outermost part 2 is in an incomplete state. FIG. 2 shows the relationship between the lower part of the outer wall WAL viewed in the A direction and the B direction indicated by arrows in FIG. 1 and other members. About the 1st jack MJ arrange | positioned at the subsequent vertical movement process, this is shown with the broken line.

  This embodiment shows a case where a three-story wooden building is constructed close to the boundary line with the adjacent land, and the building central part 1 in FIG. It is fixed on the foundation 3 and completed including the floors of each floor. In addition, the arrangement | positioning of the pillar shown in the figure and a horizontal member is not limited at all, Of course, it changes suitably.

  In the state of FIG. 1, outer walls WAL are temporarily installed on the left and right sides of the completed building central part 1, and the temporarily installed outer walls WAL are moved to the target position shown in FIG. It is necessary to fix to the foundation 3 extended in the up-down direction of FIG. Then, a framework of the wooden building is completed through a final process in which a horizontal member or the like is fixed between the fixed outer wall WAL and the building center portion 1 to construct the outermost buildings 2 and 2 of the building.

  In the state of FIG. 1, a guide plate 6 is fixed to the end of the base 4 extending in the left-right direction, and the foundation 3 is concealed by the guide plate 6 extending beyond the base 4 (FIG. 2 ( b)). Under the guide plate 6 extending beyond the base 4, a temporary wood 8 having the same height as the base 4 is arranged and fixed to the guide plate 6.

  As shown in FIG. 2, the guide plate 6 is provided with two rows of guide rails RL in a triangular plate shape, and stoppers SP are fixed to the base end and the end of each guide rail RL. As illustrated, the outer wall WAL is constructed on a carriage 7 provided with two wheels, and the two wheels are rotatably disposed on the corresponding rail RL. The carriage 7 is screwed in the horizontal direction with respect to the base material 5 constituting the outer wall WAL, and the removal thereof is easy.

  As described above, in this embodiment, it is assumed that a three-story wooden building is constructed, and it is practically impossible to configure the outer wall WAL with through pillars. Therefore, in this embodiment, the upper and lower tube pillars 11 and 12 are made continuous through the horizontal member 10 to construct a three-story structure.

  In addition, the upper and lower tube columns 11 and 12 are connected to each other, and a supplementary column 9 is disposed inside the tube column, and these are fixed to the upper and lower tube columns 11 and 12, respectively. Further, the metal plate PT is fixed so as to cover the upper and lower tube columns 11 and 12 and the auxiliary column 9, thereby reinforcing the integrity of the upper and lower tube columns 11 and 12 and the auxiliary column 9. Yes.

  In the horizontal movement process, the outer wall WAL reinforced by the accessory pillar 9 and the metal plate PT is pressed by a link member LNK described later, and moves horizontally on the guide rail RL to a target position. The target position is directly above the temporary wood 8 set to the same height as the base 4 (see FIG. 2).

  As shown in FIG. 2B, a separation distance D defined by the height of the carriage 7, the guide plate 6, the base 4, and the like is formed between the lower end surface of the outer wall WAL (base material 5) and the foundation 3. In the horizontal movement process, the lower end surface of the outer wall base material 5 moves along the illustrated reference line ST.

  FIG. 3 shows a plan view of the outer wall WAL moved to the target position, and the outer wall WAL at this time is located immediately above the temporary wood 8 shown in FIG. Even in this completed movement state, the distance between the lower end surface of the outer wall base material 5 and the foundation 3 is D.

  Next, it is necessary to raise the outer wall WAL at this position slightly to remove the carriage 7, the guide plate 6, and the temporary wood 8, and then lower the outer wall WAL onto the foundation 3. Therefore, a plurality of first jacks MJ are arranged at appropriate positions to hold the lower end surface of the outer wall WAL (base material 5) moved to the target position. As shown by a broken line in FIG. 2A, the plurality of first jacks MJ are arranged at an appropriate interval on the foundation 3 on which the outer wall WAL is to be placed.

  Next, the plurality of first jacks MJ are lifted all at once to raise the outer wall WAL by a predetermined amount (U), thereby forming a work space for removing the carriage 7 and the guide plate 6.

  And after removing unnecessary things, such as temporary wood 8 and the trolley | bogie 7, the some temporary base 13 is arrange | positioned so that it may span between the bases 4 from which the guide plate 6 was removed. In FIG. 3A, a temporary base 13 spanned between adjacent bases 4 is described in a mesh pattern. Note that the temporary base 13 on the base 4 does not appear in FIG.

  Next, an appropriate number of second jacks WK are arranged on the temporary base 13. Although not particularly limited, in FIG. 3, three second jacks WK are arranged corresponding to one outer wall WAL. Then, by raising the plurality of second jacks WK, a gap is formed between the first jack MJ and the outer wall WAL, and all the first jacks MJ are removed.

  Subsequently, it is necessary to lower the outer wall WAL onto the foundation 3, and FIG. 4 shows a start state in which a lowering operation is to be executed. 4A is a drawing in the AA direction indicated by an arrow in FIG. 3, and FIG. 4B is a drawing in the BB direction. The drawing is placed on the temporary base 13 spanned on the base 4. A state in which the two jacks WK are arranged is shown. Note that at this timing, the carriage 7, the guide plate 6, the temporary wood 8, and the first jack MJ are all removed, and thus are indicated by broken lines.

  In the state shown in FIG. 4, the base material 5 of the outer wall WAL is placed on the foundation 3 by lowering the outer wall WAL by a predetermined length D + U by lowering the plurality of second jacks WK synchronously. Can do. Here, the rising amount U is set to the minimum value necessary for the removal operation of the unnecessary material, and the descending amount D is the height of the reference line ST. In this embodiment, as shown in FIG. The base 4, the guide rail RL, the carriage 7, etc. are uniquely determined based on the height dimensions.

  When the left and right outer walls WAL and WAL are subjected to the horizontal movement process and the vertical movement process described above and the two outer walls WAL and WAL are fixed to the foundation 3, the installation work of the outer wall WAL is completed. Therefore, after that, when the building outermost portions 2 and 2 are constructed by fixing a horizontal member or the like between the outer wall WAL and the center portion 1 of the building, the framework of the wooden building is completed. In addition, about the left and right outer walls WAL, WAL, after finishing the final installation of one outer wall WAL, it is common to shift to the installation of the other outer wall WAL, but according to the present invention, the left and right outer walls WAL, WAL can be moved horizontally at the same time.

  The procedure for completing the framework of the wooden building has been described above. Next, the link member LNK used in the horizontal movement process and the vertical movement process will be described.

  FIG. 5 is a perspective view showing the link member LNK. As shown in the figure, the link member LNK has a movable main body 20 capable of appropriately extending the axial length, and swing arms 21 (21L, 21R) arranged at both ends of the movable main body 20. It is configured.

  As shown in FIG. 7, the movable main body 20 is configured to include an outer tube 22 having a screw formed at the distal end, and an inner tube 23 inserted from the distal end side of the outer tube 22. Abutting plates 24 and 25 are fixed to the proximal end side of the inner tube 23 so as to be orthogonal to the axial direction of the movable main body 20. Cylindrical bodies 26 and 27 are fixed to the contact plates 24 and 25, respectively. In addition, two operation handles HD are arranged on the threaded portion of the outer tube 22 so that the threaded portion is screwed. The cylindrical bodies 26 and 27 are formed with vertical through holes (not shown) parallel to the plate surfaces of the contact plates 24 and 25.

  As shown in FIG. 5, a pair of outer grooves GV extending in the shape of a long hole in the axial direction are formed in the threaded portion of the outer tube 22 at symmetrical positions in the radial direction. Further, the inner tube 23 is formed with a pair of round holes HO penetrating the inner tube 23 in the radial direction. In this embodiment, the pair of round holes HO are formed at a plurality of locations (three locations) apart from each other in the axial direction of the inner tube 23.

  When the movable main body 20 having such a configuration is used, the holding pin PN is inserted from one side of the outer groove GV between the two operation handles HD and HD, and the round hole HO of the inner tube 23 is formed. After passing through, it appears on the other side of the outer groove GV. Then, the holding pin PIN and the inner tube 23 are integrated, and the movement of the holding pin PN in the left-right direction is restricted by the operation handles HD, HD, so that the movable main body 20 can freely expand in the left-right direction. Is prevented.

  Then, when the two operation handles HD and HD are rotated in the same direction with the holding pin PN sandwiched between the operation handles HD and HD, the holding pin corresponds to the fact that the operation handle HD rotates the screw portion. PN moves in the axial direction of the movable main body 20, and the inner tube 23 integrated with the holding pin PN also moves in the axial direction of the movable main body 20 together with the movement of the holding pin PN.

  FIG. 6 illustrates the relationship between the left and right contact plates 24 and 25 of the movable main body 20 and the left and right swing arms 21L and 21R. As shown in FIG. 6A, the left swing arm 21 </ b> L is connected to the inner tube 23, and is fixed to the columnar shaft 30 (FIG. 7) penetrating the cylindrical body 27 and both ends of the columnar shaft 30. The connecting rod 31 includes a connecting rod 32 that connects the lower ends of the two connecting rods 31 to each other.

  On the other hand, as shown in FIG. 6B, the right swing arm 21 </ b> R is connected to the outer tube 22, and is fixed to the columnar shaft 33 (FIG. 7) penetrating the cylindrical body 26 and both ends of the columnar shaft 33. The connecting rod 34 and the connecting rod 35 for connecting the lower ends of the two connecting rods 34 to each other are provided.

  Here, the cylindrical shaft 30 and the cylindrical shaft 33 are formed with through holes in the radial direction corresponding to the through holes of the cylindrical bodies 27 and 26, and bolts BT are inserted into the through holes as necessary. And can be tightened with nuts. As shown in FIGS. 5 and 6, when the bolt BT is inserted into the through hole and tightened with a nut, the movable main body 20 and the left and right swing arms 21L and 21R are integrated.

  In this integrated state, when the link member LNK is positioned in the horizontal state, the angle α formed by the left and right connecting rods 31 and 34 with the vertical line corresponds to the thickness W of a general column material. As shown in FIG. 8, Sin (α) = z / R. Here, z = W / 2 + y, and y is the shortest distance from the center point of the cylindrical bodies 26 and 27 to the column surface (see FIG. 8). With this configuration, when the link member LNK is set in a horizontal state, the left and right contact plates 24 and 25 face each other in parallel with the column surface, and when the operation handle HD is operated, the movable main body portion The 20 contact plates 24 and 25 effectively press the left and right column surfaces.

  As shown in FIG. 8, when the link member LNK is used, the left and right connecting rods 32 and 35 are inserted into the facing column members, respectively. Therefore, in a state in which the movable main body 20 and the swing arm 21 are integrated, when the column member moves up and down, the movable main body 20 and the swing arm 21 are connected to the connecting rod 32 following the vertical movement. , 35 as a fulcrum.

  In this case, since the separation distance between the connection rod 32 and the connection rod 33 changes due to the vertical movement of the column material, in principle, stress is applied to the column material. However, in actuality, if the vertical movement range is small due to play provided around the connecting rods 32 and 35 and other appropriate play provided at the connecting portion of the link member LNK, no stress is applied to the column material. Never give. This point has been confirmed by the present inventor by repeatedly performing a lifting experiment in an actual building.

  When one or both bolts BT are removed, when the facing column member moves up and down, the left and right connecting rods 31 and 34 swing around the connecting rods 32 and 35 and the two cylinders The movable main body 20 swings around one or both of the shafts 30 and 33 as a fulcrum, and no stress is applied to the pillar material even when the vertical movement range is large.

  In this embodiment, the outer wall WAL is moved horizontally using the link member LNK that operates in this manner, and subsequently, the outer wall WAL is moved up and down, so that the construction can proceed extremely smoothly. . Moreover, since the link member LNK shown in FIGS. 5-6 can be easily comprised if the pipe support which is a general purpose product is remodeled, it is effective also in suppressing construction cost.

  Hereinafter, the operation of the link member LNK will be described just in case. FIG. 8 shows a state in which the link member LNK is bridged between the outermost column member 50 of the building center portion 1 and the column member 51 of the outer wall WAL. In this case, the movable main body 20 and the left and right swing arms 21L and 21R are integrated by tightening the nut of the bolt BT.

  The connecting rods 32 and 35 of the left and right swing arms 21 are disposed so as to penetrate the column member 50 and the column member 51 of the outer wall WAL in a direction orthogonal to the drawing. Here, the through holes of the column members 50 and 51 are formed in a size having a margin at a position of a depth W / 2 from the surface of each column. Therefore, the entire contact plates 24 and 25 of the movable main body 20 are in contact with the left and right column surfaces. A plurality of link members LNK are arranged at appropriate positions, but the connecting portions of the upper and lower tube pillars 11 and 12 are positioned between the tube pillars 11 and 12 by arranging the link member LNK on the auxiliary pillar 9. It is preferable to adopt a configuration in which the horizontal member 10 (see FIG. 2) to be pressed is pressed by the contact plate 24 or the contact plate 25.

  Subsequently, the function of the link member LNK will be described in detail. In the following description, FIG. 8 shows a state in which the horizontal movement process of the outer wall WAL has been completed, and the subsequent vertical movement process starts. Assume. Further, the radius of rotation of the connecting rod 31 and the connecting rod 34 is R, and the shortest distance from the center of the cylindrical bodies 27 and 26 and the column surface is y. In such a case, the relationship of Sin (α) = z / R and Cos (α) = SQR / R is established with respect to the initial angle α formed by the connecting rods 31 and 34 with the vertical line at the start of the vertical movement process. To do.

As described above, z = W / 2 + y, W is the left-right width of the column members 50 and 51, and in FIG. 8, it is assumed that the two column members 50 and 51 have the same width. Further, SQR = route (R ² −z ² ), and in the following description, the separation distance between the two column members 50 and 51 is T.

  As described with reference to FIG. 4, in the vertical movement process, in the state of FIG. 8, the outer wall WAL is increased by the increase amount U, and then is decreased by the decrease amount D + U (the decrease amount D from the reference line ST). In the example, the link member LNK is used in the bolted state in the horizontal movement process unless the ascent amount U and the descending amount D are particularly large. Therefore, in the present embodiment, the link member LNK in which the movable main body 20 and the left and right swing arms 21 are integrated follows the vertical movement of the column member 51.

  FIG. 9 illustrates a state in which the outer wall WAL is lowered to the target position. In this case, the separation distance between the swing centers OO ′ of the left and right swing arms 21L and 21R is always T + W, W is the lateral width of the column members 50 and 51, and T is the width of the column members 50 and 51. The separation distance. Then, since the left outer wall WAL is lowered, if the free rotation of the link member LNK is allowed, the link member LNK will rotate about the swing center O of the right swing arm 21 and the left swing wall WAL. The drop amount D of the swing center O ′ of the moving arm 21 is (T + W) Sin (θ) in principle. Note that θ is an angle formed by the O-O ′ line with the horizontal line. Further, the horizontal movement amount of the swing center O ′ of the left swing arm 21, that is, the horizontal deviation δ is theoretically δ = (T + W) (1−Cos (θ)).

  However, when the amount of descent D is small and the condition of D << (T + W) is satisfied, (T + W) (1−Cos (θ)) ≈0, and in this embodiment, the left and right oscillations Since the appropriate play is provided at the swing centers O and O ′ of the arm 21 and the connecting portions of the link member LNK, the horizontal deviation δ can actually be made zero. Incidentally, even when the condition of D << (T + W) is not satisfied, for example, when T + W = 910 mm and D = 200 mm, the theoretical value of the horizontal deviation δ is about 22 mm. It is fully absorbable by playing.

  In this embodiment, since the integrated link member LNK functions as a brace that connects the two column members in the up and down movement process, the column member can be prevented from falling down.

  By the way, for example, when the bolting of the left swing arm 21L is released and the movable main body 20 can be freely rotated, the amount of lowering can be further increased. FIG. 10 illustrates this relationship, and shows a state in which the movable main body 20 is rotated by an angle θ from the horizontal state. In this case, since the connecting rod 31 of the left swing arm 21L rotates freely with respect to the movable main body 20, the angle with the vertical line is β. Therefore, the relational expression shown in FIG. 10 is established with respect to the separation distance T and the descending amount D, and by solving this, the inclination angle θ + α of the connecting rod 34 of the right swing arm 21R and the left swing arm 21L The inclination angle β of the connecting rod 31 can be uniquely specified. Further, since the maximum descent amount D 'can be specified based on the equation shown in FIG. 10, an appropriate descent amount D can be set within the range.

  If the maximum drop amount D 'is exceeded, the left and right column members are attracted by the link member LNK, so that there is a risk that the outer wall WAL falls inward. In FIG. 10, the case where the maximum drop amount D ′ is exceeded is shown by a broken line for reference.

  As mentioned above, although the Example of this invention was described in detail, the concrete description content does not specifically limit this invention. For example, the connecting rods 31 and 34 of the left and right swing arms 21 may be freely rotated with respect to the movable main body 20, and in this case, the maximum lowering amount D ′ can be further increased. .

  Further, the link member LINK is not limited to the configuration shown in FIG. 5, and it is preferable that the axial length in the stretched state is shorter. That is, the left and right outer walls WAL are each temporarily installed in a state where they are held in the center 1 of the building. Therefore, if the outer wall WAL is as close as possible to the center 1 of the building, sufficient work can be performed outside the outer wall WAL. Space can be secured, which is preferable.

  FIG. 11 is a diagram illustrating a more preferable link member LNK ′. As shown in the figure, the link member LNK 'includes a movable main body portion 20 and swing arms 21L and 21R disposed at both ends of the movable main body portion 20 as in the case of FIG.

  The movable main body 20 includes an outer tube 22 formed with a screw in the axial direction, an adjustment tube 40 inserted into the outer tube 22, and an inner tube 23 inserted into the adjustment tube 40. ing. Except that the adjusting tube 40 is inserted, the link member LNK ′ in FIG. 11 is substantially the same as the link member LNK in FIG. 5, and the contact plate is disposed on the proximal end side of the outer tube 22 and the inner tube 23. 24 and 25 are fixed. Further, swing arms 21L and 21R are swingably attached to the outer tube 22 and the inner tube 23 through cylindrical bodies 26 and 27 (FIG. 11B) fixed to the contact plates 24 and 25, respectively. Yes.

  An outer groove GV extending in the shape of a long hole in the axial direction is formed in the screw portion of the outer tube 22, and an operation handle HD is disposed in the screw portion. In addition, the inner tube 23 and the adjustment tube 40 are formed with round holes HO at corresponding positions, and the holding pin PN is inserted, so that the outer tube 22 and the adjustment tube 40 or the adjustment tube 40 The tube 23 is integrated. In FIG. 11, for convenience, one operation handle HD is shown, but a plurality of operation handles are used as necessary.

  This link member LNK 'is bridged between the outer wall WAL and the pillar in the center 1 of the building, as in the embodiment of FIG. FIG. 11A shows this temporarily installed state. In this state, the operation handle HD is rotated in the forward direction to penetrate the outer groove GV of the outer tube 22 and the round hole HO of the adjusting tube 40. The first pin PN1 to be moved is moved leftward. Then, the adjustment pipe 40 integrated with the first pin PN1 moves to the left, so that the inner pipe 23 pressed by the adjustment pipe 40 moves to the left, and the outer wall WAL also moves to the left correspondingly. To do.

  Then, when the adjustment tube 40 and the inner tube 23 move to the limit position shown in FIG. 11B, the operation handle HD is reversely rotated and moved to the right while the outer wall WAL is appropriately held and adjusted. The tube 40 is also moved in the right direction. Next, the 2nd pin PN2 is inserted through the front-end | tip part of the adjustment pipe | tube 40, and the base end part of the inner pipe | tube 22, and both are integrated. As shown in FIG. 11C, in this state, the inner tube 22 protrudes appropriately from the adjustment tube 40.

  Next, when the adjustment tube 40 and the inner tube 23 are moved to the left by rotating the operation handle HD in the forward direction, the outer wall WAL can be moved to the target position correspondingly.

  Although simplified, the number of reciprocating movements of the operation handle HD and the number and position of the round holes HO can be changed as appropriate. Further, if the number of the adjusting pipes 40 is increased, the movement distance of the outer wall WAL, that is, the dimensional difference between the link member LNK 'when contracted and the longest link member LNK' can be increased.
