Description

[Technical Field]

[0001] The present invention relates to an architectural wall structure, and more particularly to an architectural wall structure in which wall panels are assembled into a rectangular area formed by a pair of columns standing on a foundation and a girder connecting the columns, and a construction method thereof. [Background technology]

[0002] As an example of such an architectural wall structure, one such as that described in Patent Document 1 is known. According to this structure, pins are driven laterally into the wall panel through the pillars. However, in a structure with a continuous rectangular area, this method makes it difficult to drive pins laterally, making construction difficult. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 7-197765 Summary of the Invention [Problem to be solved by the invention]

[0004] In view of the above-mentioned conventional circumstances, an object of the present invention is to provide an architectural wall structure that is easy to construct and has high strength, and a construction method thereof. [Means for solving the problem]

[0005] In order to achieve the above object, the architectural wall structure according to the present invention is characterized in that a wall panel is incorporated into a rectangular area formed by a pair of columns standing on a foundation and a girder beam connecting them, metal flanges fixed to the columns are extended to the wall panel, grooves are formed on the side of the wall panel that allow the panel to slide up and down relative to the flange, drift pins are driven into through holes formed in the flange and holes formed in the wall panel in a direction intersecting the plane of the wall panel and fixed therein, and a shear key is interposed between the foundation and the girder beam and the wall panel.

[0006] The operation of the present invention will be explained with reference to Figure 15. A typical structure in which a girder beam and a column are rigidly connected functions as a "rigid connection" (shown on the left side of the figure). However, the architectural wall structure of the present invention can function as a "pin connection" (shown on the right side) that allows for slight angular displacement. When a vertical load is applied, a moment generated in the girder beam also occurs in the column in a rigid connection, whereas a pin connection only generates a moment in the girder beam. Furthermore, when a horizontal load is applied, a moment also occurs in the girder beam and column in a rigid connection, but in a pin connection, the horizontal load is supported by the wall panel, shear key, and drift pin, so no moment occurs in the girder beam or column. As a result, even a pin connection that does not rigidly connect the girder beam and column can reasonably withstand vertical and horizontal loads, and can be constructed by simply driving pins, making construction easy. Of course, even when the girder beam and column function as a rigid connection, the pin connection still supports horizontal loads, improving the overall load resistance.

[0007] Furthermore, the horizontal bearing capacity is achieved by storing the flange in a groove formed on the side of the wall panel and driving in the drift pin by sliding the wall panel up and down. Furthermore, the shear key can be inserted from the top and bottom during construction, which also easily achieves horizontal bearing capacity. The drift pin can be driven from the front or back of the wall, making construction easy.

[0008] In addition to the above, another flange of another metal fitting fixed on the column may be extended to the girder beam, and another groove that can slide up and down relative to the other flange may be formed on the side of the girder beam, and the groove formed on the side of the wall panel may also slide up and down relative to the other flange, and drift pins may be driven into the through holes formed in the other flange and the holes formed in the girder beam in a direction intersecting the plane of the wall panel and fixed thereto.

[0009] With this configuration, other metal fittings used to join the girder beams do not interfere with the sliding movement of the wall panel, allowing the girder beams to be attached rationally and facilitating construction.

[0010] In the above configuration, the wall panel and the girder and / or the column may be of the same thickness. According to this configuration, if the wall panel and the girder are of the same thickness, there is no obstruction of the view in the vertical direction. On the other hand, if the wall panel and the column are of the same thickness, the column does not obstruct the view in the horizontal direction. As a result, a spacious space is created.

[0011] In the above-mentioned configuration, the key insertion holes in the girder beam and the wall panel into which the shear key is inserted may be formed in the vertical direction. In the above-mentioned construction, the shear key can be inserted vertically, which makes the construction more efficient.

[0012] In the above configuration, the key insertion holes of the wall panel into which the shear keys are inserted in the vertical direction may be formed symmetrically in pairs on the left and right upper surfaces of the wall panel when viewed from the front, and may be capable of inserting a lifting weight. According to this configuration, during the above construction, the wall panel is lowered while being appropriately positioned between a pair of pillars, and after the construction is smoothly completed, the shear keys can also be easily installed.

[0013] In the above configuration, the key insertion hole of the wall panel into which the shear key is inserted may be formed in one location on the lower surface of the wall panel at the center of the left and right sides when viewed from the front. According to this configuration, when inserting the lower shear key into the key insertion hole while lifting the wall panel, adjustment is easy if there is only one location, improving construction efficiency.

[0014] In the above configuration, a notch may be provided at the outer corner of the wall panel, and a water stop may be provided between the notch and the column. This configuration prevents water from entering the interior from the outside through the gap between the column and the wall panel. Moreover, it is possible to make the column and the wall surface flush.

[0015] In the above configuration, an outer panel wider than the column may be attached to the outer surface of the column, and a water stop may be provided between the back surface of the outer panel and the wall panel. This configuration prevents water from entering the interior from the outside through the gap between the column and the wall panel. Moreover, the water stop is not visible from the outside, so it does not detract from the aesthetic appearance.

[0016] In the above configuration, a notch may be provided on the side surface near the inner corner of the wall panel, and a water stop may be provided between this notch and the column. In the case of CLT, etc., which will be described later, if there are knots or the like in the laminated wood, water may seep into the interior through these knots, and this water stop prevents water that has entered through the knots or the like from seeping into the interior.

[0017] In the above-mentioned configuration, the pillar may be formed so that its front-to-back depth is greater than its left-to-right width when viewed from the front of the wall panel. With this configuration, the strength of the building against wind pressure in a direction perpendicular to the wall panel can be improved.

[0018] In each of the above configurations, the wall panel may be made of CLT.

[0019] In addition, in each of the above configurations, the drift pin may be removable, and the hole formed in the wall panel may be a through hole, so that the drift pin can be removed, and the components can be dismantled and re-installed.

[0020] In each of the above configurations, the girder may connect the pair of columns via beams provided on each of the columns.

[0021] On the other hand, in order to achieve the above object, the construction method of the architectural wall structure according to the present invention is characterized in that it is a method of incorporating a wall panel into a rectangular area formed by a pair of columns standing on a foundation and a girder beam connecting them, in which a metal flange is fixed to the column and extends to the wall panel, a groove that can slide up and down relative to the flange is formed in advance on the side of the wall panel, a drift pin driven from a hole formed in the wall panel in advance can be passed through a through hole formed in the flange in advance, and a lower shear key is protruded upward from the base part between the pair of columns. a key insertion pilot hole is formed in the lower surface of the wall panel, and key insertion holes for inserting an upper shear key are formed in the upper surface of the wall panel and the lower surface of the girder beam; the wall panel is moved from above to below while sliding the groove relative to the flange between the pair of columns; the lower shear key is inserted into the key insertion pilot hole; the girder beam is lowered from above to below while inserting the upper shear key into the key insertion hole; and the drift pin is driven commonly into the hole in the wall panel and the through hole in the flange, thereby fixing the girder beam to the pair of columns.

[0022] In the above characteristic method, another flange of another metal fitting is fixed to the column and extended to the girder beam, another groove that can slide up and down relative to the other flange is formed in advance on the side of the girder beam, a drift pin driven from a hole pre-formed in the girder beam can be passed through a through-hole pre-formed in the other flange, the wall panel is moved from above to below between the pair of columns while sliding the groove relative to the other flange and the flange, the girder beam is moved from above to below between the pair of columns while sliding the other groove relative to the other flange, and the drift pin is driven commonly into the hole in the girder beam and the through-hole in the other flange, and the girder beam is fixed to the pair of columns.

[0023] In addition, in each of the above characteristic methods, the key insertion holes of the wall panel may be formed symmetrically in pairs on the left and right upper surfaces of the wall panel when viewed from the front, and weights may be inserted into the pair of key insertion holes of the wall panel, the wall panel may be lowered from above via the weights, the weights may be removed from the key insertion holes of the wall panel, and the upper shear key may be inserted, and the girder may be moved from above to below.

[0029] The present invention will now be described in more detail with reference to the accompanying drawings. The architectural wall structure according to the present invention is composed of the structures and members shown in Figures 1 to 14 and 16 to 22, and its effects are shown in the second column of Figure 15.

[0030] As shown in Figures 1 to 6, columns 11 and beams 12 are joined in that order onto a concrete foundation 10, and a girder beam 13 is joined onto the column 11 via the beam 12 and beam support hardware 40A, 40C, forming a rectangular space into which CLT 14 wall panels are installed.

[0031] The parts and structure of each member are shown below: The drift pin 20 shown in Figure 11 has a tapered portion 21 and a knurled retainer 22, and can be pulled out by threading the male screw into the female screw portion 23.

[0032] 3, 4, 5c, and 13a-d, the column base support 30 is configured such that an anchor bolt 31 integrated with the foundation 10 is fixed in an end hole 32y of the column base 32 via a long-hole washer 32a and a nut 34, and a column base metal fitting 33 is inserted into a central hole 32x for fixation. The drift pin 20 is driven into a through-hole formed in the column base metal fitting 33 and the lower end of the column 11 and fixed therein.

[0033] The beam support hardware 40 shown in Figures 3, 4, 5a-d, 8a-d, 9a-d, and 10 comes in different sizes 40A-40C, and each has a first hardware 41 and a second hardware 42 positioned on both sides of the column 11 and beam 12, and fastened to web holes 45a and web nuts 45b between a pair of webs 45 with flange bolts 43 passing through them. The pair of flanges 44 slide into grooves formed in the sides of the CLT 14 and girder beam 13, and similar through holes h are formed in the CLT 14 and girder beam 13 at positions that match the multiple through holes 44a (H) formed in the flanges 44, and drift pins 20 are driven in.

[0034] The through-holes (h) may be configured as holes with a bottom, and in this specification, the term "hole" refers to both holes with a bottom and through-holes. If the through-holes (h) are configured as holes, the drift pins 20 can be driven in from either direction, which promotes the reuse of the CLT 14. It is not necessary to use all of the multiple through-holes (holes) (h); selective use of some of them further promotes the reuse of the CLT 14.

[0035] The tenon pipes 50 and tenon pipes 51 shown in Figures 3, 4, and 12c to 12f have through holes H oriented in different directions and are inserted into holes between the pillars 11 and beams 12, and drift pins 20 are driven into the through holes formed in the pillars 11 and beams 12 to secure them in place.

[0036] The upper shear key 60 shown in Figures 6, 7a, 7b, 12a, 12b, 18a, and 18b is inserted into holes formed in the girder beam 13 and the CLT 14, and the drift pins 20 are driven into and fixed in the through holes formed in the girder beam 13 and the CLT 14.

[0037] The leg shear key structure 70 shown in Figures 6 and 14a-d has an anchor plate 73 and anchor bolts 72 fixed to the foundation 10, and a leg shear key 71 bolted to these. The tie bar 83 shown in Figures 2bc, 4 and 5 is fixed to the beam 12 via a truss bracket 81 and a clevis 82, and is fastened to other beams, columns, etc. to support the structure.

[0038] As shown in Figures 5a, 5b, 18a-d, and 19a, grooves 13a, 14a are formed on both sides of the girder beam 13 and CLT 14 to receive the pair of flanges 44 of the beam support hardware 40 and allow it to slide up and down. The upper beam support hardware 40B, 40C in Figures 18a and 18c have the same flange 44 width as the lower beam support hardware 40B in the same figures, and the grooves 13a, 14a can be slid up and down in common.

[0039] As shown in Figures 7a-d, 18a, and 18b, when assembling the CLT 14, without the girder 13 in place, a pair of upper shear keys 60 driven into the top of the CLT 14 are fixed with drift pins 20. The pin body 101a of the lock pin 101 of the lifting weight suspension hardware 100 is passed through these and secured with the front plate 101b, after which the lifting weight is suspended and the leg shear keys 71 are inserted into the holes in the bottom of the CLT 14. The front plate 101b is inserted into the slit 101c and rotatably fixed with the spring pin 101d.

[0040] The flanges 44 of the beam support hardware 40B at four locations on each side fit into grooves in the CLT 14, and multiple drift pins 20 are driven into through holes 44a in the flanges 44 through through holes formed in the CLT 14, allowing the CLT 14 to support the shear force in the vertical direction.

[0041] Thereafter, the lifting hardware 100 is removed, and the girder beam 13 is attached to complete the structure. After the lifting hardware 100 is removed, the upper shear key 60 is inserted into a hole formed in the girder beam 13, and the drift pin 20 is driven into the through hole formed in the girder beam 13 and the through hole 44a of the beam support hardware 40, and fixed.

[0042] 19a-d and 20 show a water-stopping structure 90 that prevents the infiltration of water from the outside due to rain, etc. In Fig. 19a, a recess 14x, which is a cutout, is provided at the outer corner of the CLT 14, and a water-stopping caulking material 91a is provided between this recess 14x and the column 11. On the other hand, in Fig. 19b, a thin column 92, which is an outer plate that is wider than the column 11, is attached to the outer surface of the column 11, and a recess 92x is provided on the back surface of the thin column 92, and a water-stopping caulking material 91a is provided between the CLT 14 and the recess 14x.

[0043] CLT 14 is sometimes formed by stacking multiple thin plates. In this case, for example, if a knot is located in the outermost thin plate near the left and right ends of the CLT 14, water may seep in from the knot behind the caulking material 91a and enter the room. To prevent such water seepage, as shown in Figures 19c and 19d, water-stopping slits 14y, which are notches, may be cut into the side of the CLT 14 near the inner corners, and water-stopping gaskets 91b may be placed between the water-stopping slits 14y and the columns 11. The water-stopping slits 14y and water-stopping gaskets 91b can also prevent wind penetration, so the water-stopping slits 14y and water-stopping gaskets 91b are provided not only on the left and right sides of the CLT 14, but also on the top and bottom.

[0044] These waterproof structures 90 can be used together with the assembly of the CLT 14, or can be installed after the assembly of the CLT 14. The caulking material 91a and the waterproof packing 91b can also be used interchangeably.

[0045] As shown in Figure 21a, by making the pillars 11 thicker than the CLT 14, it is possible to improve the resistance to wind force acting on the plane of the CLT 14, as described above. On the other hand, as shown in Figure 21b, the short sides of the pillars 11 may be arranged in the thickness direction of the CLT 14, making the CLT 14 and the pillars 11 the same thickness. In the latter case, the spacing between the CLT 14 is wider than in the former case, but the pillars 11 do not block the horizontal space inside the room.

[0046] As shown in Figure 22a, by making the girder beam 13 thicker than the CLT 14, the strength of the girder beam 13 against vertical loads can be improved, as described above. On the other hand, as shown in Figure 22b, the CLT 14 and the girder beam may be made the same thickness. In the latter case, the girder beam 13 does not obstruct the vertical space inside the room as much as in the former case.

[0047] In each of the above-described embodiments, the girder beam 13 is configured to connect a pair of columns 11, 11 via a beam 12 provided above each column 11. However, as shown in Figure 23, a beam support metal fitting 40 may be fixed to each of the pair of columns 11, 11, and a girder beam 13 (13') may be attached to the pair of columns 11, 11. Furthermore, when a lower shear key is provided on the girder beam 13' provided in the middle of the column 11, an upper shear key identical to or having a similar structure to the upper shear key denoted by reference numeral 60 may be used instead of the leg shear key.

[0048] The above-described embodiments can be combined with each other and can be modified as appropriate without departing from the spirit of the present invention. [Industrial Applicability]
