[0006] By the way, it is conceivable to attach a building construction accuracy adjusting jig to a structural member such as a column or a wall and adjust the inclination of the structural member.

[0007] In this case, for example, the building construction accuracy adjusting jig must be fixed to the structural member by temporary bolts, and it takes time and effort to install and remove the temporary bolts.

[0008] In consideration of the above facts, an object of the present invention is to easily fix a building construction accuracy adjusting jig to a structural member. ​[Means for solving the problem]

[0009] The erection accuracy adjustment jig according to claim 1 comprises a fixing part that is detachably fixed to a level adjustment bolt provided on the upper end surface of a structural member to be erected, and a support mounting part to which an extension support is attached.

[0010] The erection accuracy adjustment jig according to claim 1 comprises a fixing part and a support mounting part. The fixing part is detachably fixed to a level adjustment bolt provided on the upper end surface of the structural member to be erected. A telescopic support is attached to the support mounting part. In this state, the inclination of the structural member is adjusted by extending or retracting the telescopic support.

[0011] In this invention, as described above, the fixing part of the erection accuracy adjustment jig is detachably fixed to a level adjustment bolt provided on the upper end surface of the structural member. This eliminates the need, for example, to temporarily install and remove temporary bolts for fixing the fixing part of the erection accuracy adjustment jig to the structural member. Therefore, the erection accuracy adjustment jig can be easily fixed to the structural member.

[0012] The erection accuracy adjustment jig according to claim 2 comprises a horizontal flange portion disposed on the upper end surface of the structural member and a vertical flange portion disposed on the side surface or wall surface of the structural member, wherein the fixing portion is provided on the horizontal flange portion and the support mounting portion is provided on the vertical flange portion.

[0013] The erection accuracy adjustment jig according to claim 2 comprises a horizontal flange portion and a vertical flange portion. The horizontal flange portion is positioned on the upper end surface of the structural member. The horizontal flange portion is provided with a fixing portion which is detachably fixed to a level adjustment bolt provided on the upper end surface of the structural member.

[0014] On the other hand, the vertical flange portion is positioned on the side or wall surface of the structural member. This vertical flange portion is provided with a support mounting section to which an expansion support is attached.

[0015] By providing a fixing portion on the horizontal flange portion disposed on the upper end surface of the structural member, the fixing portion can be easily fixed to the leveling adjustment bolt provided on the upper end surface of the structural member.

[0016] The building erection accuracy adjusting jig according to claim 3 includes a fixing step of detachably fixing the building erection accuracy adjusting jig to a leveling adjustment bolt provided on the upper end surface of the structural member, and an adjustment step of expanding and contracting the telescopic support attached to the building erection accuracy adjusting jig to adjust the inclination of the structural member.

Mode for Carrying Out the Invention

[0021] Hereinafter, an embodiment will be described with reference to the drawings.

[0022] (Column) In FIG. 1, a column 30 during construction (during erection) by the construction method of the structural member according to the present embodiment is shown. The column 30 is, as an example, a wooden column (wooden pillar). Further, the column 30 is formed in a prismatic shape. Note that the column 30 is an example of a structural member.

[0023] (Fireproof board) As shown in FIGS. 2, 3, and 4, the column 30 has four side surfaces 30S. A fireproof board 36 is attached to each side surface 30S of the column 30. The fireproof board 36 is, for example, a gypsum board, a calcium silicate board, etc., and is attached to each side surface 30S of the column 30 by an adhesive, screws, etc. Note that the fireproof board 36 is an example of a fireproof coating material and a coating material.

[0024] The fireproof boards 36 are attached to each side surface 30S of the column 30 in a state of being laminated in a plurality of layers (in this embodiment, three layers). The column 30 is fireproof coated by these fireproof boards 36. Further, a side surface 36S of the column 30 is formed by the outer surface of the fireproof board 36.

[0025] Note that the fireproof board 36 is not limited to a plurality of layers and may be a single layer. Further, the fireproof board 36 can be omitted as appropriate.

[0026] (Cover plate) As shown in Figure 2, a cover plate 46 is provided on the upper end surface of the column 30. The cover plate (sealing plate) 46 is made of steel plate or the like. The cover plate 46 is superimposed on the upper end surface of the column 30, covering substantially the entire upper end surface.

[0027] A through hole is formed in the center of the cover plate 46, leading to a mounting hole 32, which will be described later. One end of the connecting pin 40 is inserted through this through hole in the cover plate 46 into the mounting hole 32 formed on the end face of the column 30.

[0028] (Leveling bolt) The cover plate 46 is provided with multiple leveling bolts 60. These multiple leveling bolts 60 are arranged around the connecting pin 40 and protrude from the upper surface of the cover plate 46. The lower surface of the joint portion 52 of the upper precast beam 50 (see Figure 5), which will be described later, rests on these leveling bolts 60.

[0029] The cover plate 46 may be provided as needed and can be omitted as appropriate. If the cover plate 46 is omitted, the level adjustment bolt 60 can be provided, for example, on the upper end surface of the column 30.

[0030] (Connecting pin) A connecting pin 40 is provided at the upper end of the column 30, which is connected to the upper precast beam 50 (see Figure 5), described later. Specifically, a mounting hole 32 is formed in the center of the upper end surface of the column 30, into which one end of the connecting pin 40 is inserted. The mounting hole 32 is a circular, bottomed hole.

[0031] The connecting pin 40 is formed in a rod shape, for example, from a round steel bar. A pair of pin holes 42 are formed at one end of the connecting pin 40. The pair of pin holes 42 are circular through holes that penetrate the connecting pin 40 in the width direction (radial direction).

[0032] As shown in Figure 3, the pair of pin holes 42 intersect (are perpendicular to) each other when viewed from the axial direction of the connecting pin 40, and are offset in the axial direction of the connecting pin 40. A pair of fixing pins 44 are inserted into this pair of pin holes 42.

[0033] The pair of fixing pins 44 are formed from rod-shaped members such as drift pins. The pair of fixing pins 44 are inserted into a pair of pin holes 42 formed in the connecting pin 40, and also into a pair of pin holes 34 formed in the side surface 30S of the column 30.

[0034] The pair of pin holes 34 are circular through-holes that penetrate the column 30 and the mounting hole 32 in the width direction. In plan view, the pair of pin holes 34 intersect (are perpendicular to each other) and are offset in the direction of the column 30's material axis. The connecting pin 40 is fixed to the column 30 by inserting the fixing pin 44 into the mutually connecting pin holes 34 and 42.

[0035] The pair of fixing pins 44 are covered by the fire-resistant board 36. Furthermore, the connecting pins 40 are not limited to the pair of fixing pins 44; they may also be fixed to the column 30 by other fixing methods, such as adhesive.

[0036] As shown in Figure 3, the other end of the connecting pin 40 protrudes from the cover plate 46 that covers the end face of the column 30. A male thread is also formed on the other end of the connecting pin 40. This other end of the connecting pin 40 is inserted into the insertion hole 54 (see Figure 5) of the upper precast beam 50.

[0037] The male thread on the other end of the connecting pin 40 may be provided as needed, but can be omitted as appropriate.

[0038] (Upper precast beam) As shown in Figure 5, the upper end of the column 30 is connected to the upper precast beam 50 via a connecting pin 40 (pin connection). The upper precast beam 50 is made of precast concrete and is manufactured, for example, in a factory or site yard. The upper precast beam 50 is made of reinforced concrete and has multiple main beam reinforcements 56 and shear reinforcements 58 embedded inside.

[0039] The upper precast beam 50 is a continuous beam. This upper precast beam 50 has a joint portion 52 that connects to the upper and lower columns 30, and a beam portion (not shown) that extends from the joint portion 52.

[0040] The lower surface of the joint 52 rests on a number of leveling bolts 60 provided on a cover plate 46 that covers the upper end surface of the column 30. This creates a joint between the lower surface of the joint 52 and the cover plate 46 that covers the upper end surface of the column 30. This joint is filled with a filler material M.

[0041] An insertion hole 54 is formed in the center of the upper surface of the joint portion 52. The insertion hole 54 is a circular through-hole that penetrates the joint portion 52 in the beam-length direction (vertical direction). The insertion hole 54 is formed, for example, by embedding a sleeve in the joint portion 52. The other end (upper end) of a connecting pin 40 provided at the upper end of the lower column 30 is inserted into the lower end of this insertion hole 54.

[0042] Multiple leveling bolts 60 are provided around the insertion hole 54 on the upper surface of the joint portion 52. The multiple leveling bolts 60 protrude from the upper surface of the joint portion 52. A cover plate 46 that covers the lower end surface of the column 20 installed above the joint portion 52 is placed on top of these leveling bolts 60.

[0043] As a result, a joint is formed between the upper surface of the joint 52 and the lower end surface of the upper column 20. This joint is filled with filler material M. In addition, by placing the cover plate 46 on top of the multiple level adjustment bolts 60, the multiple level adjustment bolts 60 do not sink into the lower end surface of the column 20.

[0044] A connecting pin 40 is provided at the lower end of the column 20. The connecting pin 40 protrudes from a cover plate 46 that covers the lower end surface of the column 20 and is inserted into the upper end side of the insertion hole 54 of the joint portion 52. In this state, the upper precast beam 50 and the columns 20 and 30 are joined by filling the insertion hole 54 with a filler material M.

[0045] The lower end of column 20 is constructed in the same way as the upper end of column 30, but inverted. Therefore, the explanation of the lower end of column 20 will be omitted as appropriate.

[0046] (Construction method for structural members) Next, an example of a construction method for the structural member according to this embodiment will be described.

[0047] (Structural component installation process) First, in the structural member installation process, the columns 30 to be erected are placed in predetermined positions on the foundation or beams (not shown).

[0048] (Fixed process) Next, as shown in Figures 1, 2, and 3, in the fixing process, the erection accuracy adjustment jig 80 is detachably fixed to the level adjustment bolts 60 provided on the cover plate 46 that covers the upper end surface of the column 30 installed in a predetermined position. In this embodiment, as an example, the erection accuracy adjustment jig 80 is fixed to adjacent level adjustment bolts 60.

[0049] Specifically, the erection accuracy adjustment jig 80 is formed, for example, from an L-shaped steel. This erection accuracy adjustment jig 80 has a horizontal flange portion 82 and a vertical flange portion 86 that are bent in an L-shape.

[0050] The horizontal flange portion 82 is positioned on a cover plate 46 that covers the upper end surface of the column 30. A fixing portion 82A is provided at one end of the horizontal flange portion 82. A U-shaped slit 84 is formed in the fixing portion (hook portion) 82A. By hooking this slit 84 onto the shaft of the level adjustment bolt 60, the fixing portion 82A is detachably fixed to the level adjustment bolt 60.

[0051] A vertical flange portion 86 is provided at the other end of the horizontal flange portion 82. The vertical flange portion 86 extends downward from the other end and is positioned on the side surface 36S of the column 30. A spacer 88 is positioned between the vertical flange portion 86 and the side surface 36S of the column 30. An ink base 90 is also attached to the vertical flange portion 86.

[0052] As shown in Figure 6, the ink base 90 has a base portion 92 and a support mounting portion 94. The base portion 92 is made of steel plate or the like. This base portion 92 is joined to the outer surface of the vertical flange portion 86 by bolts 96 and nuts 98 while overlapping it. The support mounting portion 94 is provided on the outer surface of this base portion 92.

[0053] The support mounting portion 94 is formed from a U-shaped curved steel rod or the like, with an open top. The support mounting portion 94 is also inclined outward as it extends downward, and its upper end is joined to the base portion 92 by welding or the like. The upper end of the telescopic support 100 (see Figure 3) is attached to the other end (curved portion) of this support mounting portion 94.

[0054] As shown in Figure 3, a pipe catch 102 is provided at the upper end of the telescopic support 100. This pipe catch 102 is detachably fixed to the support mounting portion 94. The lower end of the telescopic support 100 is fixed to a beam or slab (not shown).

[0055] (adjustment process) Next, as shown in Figure 1, in the adjustment process, the telescopic support 100 attached to the erection accuracy adjustment jig 80 is extended or retracted to adjust the inclination of the column 30.

[0056] Specifically, the telescopic support 100 has a telescopic section 104 that expands and contracts in the axial direction. The telescopic section 104 has an outer cylinder 104A and an inner cylinder 104B that is slidably inserted into the outer cylinder 104A. By sliding the inner cylinder 104B relative to the outer cylinder 104A, the telescopic support 100 expands and contracts. This adjusts the inclination of the column 30.

[0057] The extension and retraction of the telescopic section 104 is restricted, for example, by a pin that passes through the outer cylinder 104A and the inner cylinder 104B. In this embodiment, two telescopic supports 100 that extend and retract in two horizontal directions are attached to the column 30 in a plan view. This makes it possible to adjust the horizontal inclination of the column 30 in two directions.

[0058] (Removal process) Next, after joining the column 30 to the foundation, beams, etc. (not shown), in the removal process, the two expansion supports 100 are removed, and the two erection accuracy adjustment jigs 80 are removed.

[0059] In this fixing process, the fixing portion 82A of the erection accuracy adjustment jig 80 is detachably fixed to the level adjustment bolt 60 provided on the upper end surface of the column 30. This eliminates the need for temporary bolts to fix the fixing portion 82A of the erection accuracy adjustment jig 80 to the column 30, for example. Therefore, the erection accuracy adjustment jig 80 can be easily fixed to the column 30.

[0060] In this embodiment, two telescopic supports 100 are attached to the column 30, but at least one telescopic support 100 can be attached to the column 30.

[0061] (Mechanism of Action and Effects) Next, the operation and effects of this embodiment will be described.

[0062] As shown in Figure 1, the erection accuracy adjustment jig 80 according to this embodiment comprises a fixing part 82A and a support mounting part 94. The fixing part 82A is detachably fixed to a level adjustment bolt 60 provided on the upper end surface of the column 30 to be erected. A telescopic support 100 is attached to the support mounting part 94. In this state, the inclination of the column 30 is adjusted by extending or retracting the telescopic support 100.

[0063] As mentioned above, the fixing portion 82A of the erection accuracy adjustment jig 80 is detachably fixed to the level adjustment bolt 60 provided on the upper end surface of the column 30. This eliminates the need for temporary bolts to fix the fixing portion 82A of the erection accuracy adjustment jig 80 to the column 30, for example. Therefore, the erection accuracy adjustment jig 80 can be easily fixed to the column 30.

[0064] Furthermore, the erection accuracy adjustment jig 80 includes a horizontal flange portion 82 and a vertical flange portion 86. The horizontal flange portion 82 is positioned on the upper end surface of the column 30. The horizontal flange portion 82 is provided with a fixing portion 82A that is detachably fixed to a level adjustment bolt 60 provided on a cover plate 46 that covers the upper end surface of the column 30.

[0065] On the other hand, the vertical flange portion 86 is positioned on the side surface 36S of the column 30. This vertical flange portion 86 is provided with a support mounting portion 94 to which the telescopic support 100 is attached.

[0066] By providing a fixing portion 82A on the horizontal flange portion 82 positioned on the upper end surface of the column 30, the fixing portion 82A can be easily fixed to the level adjustment bolt 60 provided on the upper end surface of the column 30.

[0067] (modified version) Next, a modified example of the above embodiment will be described.

[0068] In the above embodiment, a slit 84 is provided in the fixing portion 82A of the lateral flange portion 82 of the erection accuracy adjustment jig 80. However, the fixing portion 82A may be provided with anything other than a slit 84, such as a hook or clip that can be detachably attached to the level adjustment bolt 60.

[0069] Furthermore, in the above embodiment, a fixing portion 82A is provided on the lateral flange portion 82 of the erection accuracy adjustment jig 80. However, the fixing portion 82A is not limited to the lateral flange portion 82, and may be provided on a bracket or other fixing member such as a frame provided on the erection accuracy adjustment jig 80 instead of the lateral flange portion 82.

[0070] Similarly, in the above embodiment, a support mounting portion 94 is provided on the vertical flange portion 86 of the erection accuracy adjustment jig 80. However, the support mounting portion 94 is not limited to the vertical flange portion 86, and may be provided on a bracket or other mounting member such as a frame provided on the erection accuracy adjustment jig 80 instead of the vertical flange portion 86.

[0071] Furthermore, in the above embodiment, the upper end of the column 30 is joined to the upper precast beam 50 via a connecting pin 40. However, the joining structure between the upper end of the column 30 and the upper precast beam 50 is not limited to the connecting pin 40 and can be changed as appropriate.

[0072] Furthermore, the upper end of the column 30 may be joined not only to a concrete beam such as the upper precast beam 50, but also to, for example, a concrete beam formed by cast-in-place concrete, a steel beam, a slab, etc.

[0073] Furthermore, in the above embodiment, the column 30 is made of wood. However, the column 30 is not limited to wood; for example, it may be made of reinforced concrete, steel-reinforced concrete, or steel.

[0074] Furthermore, in the above embodiment, the structural member is a column 30. However, the structural member is not limited to a column 30, but may also be a wooden wall, a concrete wall, a steel wall, or the like. In this case, the vertical flange portion 86 of the erection accuracy adjustment jig 80 is positioned on the wall surface or side surface of the wall.

[0075] Although one embodiment of the present invention has been described above, the present invention is not limited to these embodiments, and various modifications may be used in appropriate combinations with one embodiment, and it goes without saying that the invention can be implemented in various forms without departing from the spirit of the present invention.
