  Hereinafter, a preferred embodiment of a wooden block support of the present invention will be described in detail with reference to the attached drawings. The wooden column support 1 according to the present embodiment is mainly provided on a pedestal 3 provided on a foundation 2 and a pedestal 3 as shown in FIGS. It is comprised from the insertion body 5 for connecting with the column base part 4a of the wooden column 4 installed above.

  The base body 3 is formed of a U-shaped member formed by bending a flat plate into a U shape, and a bottom wall 3a and a pair of left and right side walls 3b and 3c raised from the left and right ends of the bottom wall 3a are formed. And the rear wall portion 3d is formed by the flat plate member welded to the rear of the U-shaped member, and the ceiling wall portion 3e is formed by the flat plate member welded to the upper portion of the flat plate member and the U-shaped member. Is formed, whereby the pedestal 3 is closed on three sides by the side wall portions 3b and 3c and the rear wall portion 3d, and the opening 6 (see FIG. 3) is formed on the front side which is one of the sides. It is formed in a rigid hollow box shape. As to the directions, the left and right direction may be the front and back direction, and therefore, the front and rear direction may be the left and right direction.

  The pedestal 3 is installed on the base 2 at the bottom wall 3a. In this pedestal 3, a wood beam 7 provided on the foundation 2 to constitute a foundation is in a direction of abutting against the side wall portions 3b and 3c, the rear wall portion 3d and the opening 6 in the front, rear, left and right direction. Be placed. In addition, on the ceiling wall 3 e of the pedestal 3, a column base 4 a of the wooden column 4 is installed.

  The wooden column 4 and the wooden beam 7 are usually formed with a square cross section of the same size, and the external dimensions of the pedestal 3 are adjusted to the sectional dimensions of the wooden column 4 and the wooden beam 7. The external form is formed into a substantially cubic hollow box.

  An anchor bolt 8 which is a joining member for joining and fixing the pedestal 3 on the foundation 2 is disposed at the center of the bottom wall portion 3a that defines the hollow internal space S inside the pedestal 3 and is formed. The hole 9 to be inserted is formed to penetrate in the vertical direction. The hole 9 allows positional deviation between the position of the anchor bolt 8 projecting upward from the foundation 2 and the position of the core of the wooden column 4 provided on the pedestal 3, thereby making the pedestal 3 a foundation 2 It is formed with a hole diameter larger than the bolt diameter of the anchor bolt 8 so that it can be installed on top.

  Of the left and right side wall portions 3b and 3c, one of the side wall portions (the right side wall portion 3c in the drawing) and the rear wall portion 3d A plurality of insertion holes 13 (see FIGS. 2 and 3) for inserting bolts 12 which are fastened to the nuts 11 and connect the pedestal 3 to the wood beam 7 are suitably formed in a predetermined number.

  The longitudinal direction end of the wood beam 7 is connected to the side wall portion 3c and the rear wall portion 3d in which the insertion holes 13 are formed, with the spacer 14 interposed therebetween. With respect to the other side wall (the left side wall 3b in the figure), the longitudinal direction end of the wood beam 7 separately fixed to the foundation 2 is abutted in a non-joining manner via the spacer 14 (See Figure 1).

  The ceiling wall 3e of the pedestal 3, that is, the flat plate material constituting the ceiling wall 3e, will be described in detail later, but as shown in FIG. 5, the slits 15 for assembling the insertion body 5 into the pedestal 3. Are vertically penetrated. Fig. 5 (A) is a bottom view of the ceiling wall portion (flat plate material) 3e, and Fig. 5 (B) is a cross-sectional view taken along the line B-B in Fig. 5 (A).

  The insertion body 5 is formed by using a flat plate member 16 and is placed on the ceiling wall 3e of the pedestal 3 so as to be inserted into the kerf formed in the column height direction in the column base 4a of the wooden column 4. In the height direction of the wooden column 4. The plate member 16 is used with its length direction oriented in the column height direction.

  In the present embodiment, as shown in FIGS. 6 and 7, the insertion body 5 is formed in a planar cross shape by using a pair of plate members 16. FIG. 6A is a front view showing one plate member 16 of the two sheets, and FIG. 6B is a front view showing the other plate member 16.

  First, the plate member 16 alone constituting the insertion body 5 will be described. The insertion body 5 may be configured of one plate member 16.

  A concave portion 16d is formed downward in the lower portion of the plate member 16 constituting the insertion body 5 in the vertical direction, and the upper portion of the plate member 16 is formed in the width direction of the lower portion of the plate member 16 by the concave portion 16d. As a result, the cross-sectional area of the plate member 16 is reduced, and a pair of leg portions 16a rich in tensile deformation ability in the longitudinal direction of the plate member 16, that is, the height direction of the wooden column 4 is formed.

  As shown in FIG. 1, in the upper part of the plate member 16, a drift pin 17 which is in communication with a pin hole (not shown) for inserting a drift pin formed in the wooden column 4 and which penetrates into the wooden column 4. The number of holes 16 b to be inserted is appropriately formed in the same arrangement on both sides in the width direction of the plate member 16. The drift pin 17 penetrates from the pin hole of the wooden column 4 to the hole 16 b of the plate member 16, whereby the wooden column 4 and the plate member 16 are integrally connected.

  At the lower end side of each leg portion 16 a of the plate member 16, a lower end joint portion 16 c to be inserted into the slit 15 formed in the ceiling wall portion 3 e of the pedestal 3 is formed. In detail, on the lower end side of the leg 16a, it is directed to the recess 16d from the lower edge of the leg 16a to the vertical height position (shown by the dimension H in the drawing) by the thickness of the ceiling wall 3e. A locking projection 16e for locking the leg 16a to the upper surface 3f of the ceiling wall 3e is formed, and a lower end portion 16c is formed below the locking projection 16e to be inserted into the slit 15 .

  The vertical dimension H of the lower end joint portion 16c is formed so as to fit within the thickness of the ceiling wall 3e by the locking projection 16e formed at the height position of the thickness of the ceiling wall 3e. And when attaching the leg part 16a of the plate material 16, ie, the insertion body 5, to the base body 3, the latching protrusion 16e is latched by the ceiling wall part 3e, and functions as positioning of the leg part 16a in the up-down direction The lower end joint portion 16c inserted in the lower end portion 15c is positioned so that the lower edge (the lower edge of the leg portion 16a) is substantially flush with the lower surface 3g of the ceiling wall 3e.

  As described above, the plug-in body 5 according to the present embodiment is configured by welding and joining together a pair of plate members 16 in a plane cross shape.

  A vertically oriented cut 18 is formed in one plate member 16 downward from the upper end, and the other plate member 16 is vertically moved upward from the upper end of the recess 16 d. Longitudinal notches 18 are formed, and the combined length of the notches 18 is made to reach the recess 16 d from the upper end of the plate member 16.

  By aligning the notches 18 of the two plate members 16 with each other and relatively moving and fitting the plate members 16 with each other in the vertical direction, as shown in FIG. The flat cross-shaped insertion body 5 is formed. In each cut 18 of the plate member 16, a narrow portion 18a having a narrow cut width and a wide portion 18b having a wide cut width are formed in the vertical direction along the column height direction. In the illustrated example, one wide portion 18 b is formed between the upper and lower two narrow portions 18 a.

  The width dimension of the narrow portion 18 a is set to about the thickness dimension of the plate member 16 so that the other plate member 16 is held by the narrow portion 18 a of the one plate member 16. Also, the width dimension of the wide portion 18 b is set to be larger than the thickness dimension of the plate member 16 in order to allow the drift pin 17 to move in the lateral direction of the wooden column 4.

  Since the front and back of one plate member 16 is directed in the left and right direction, and the front and back of the other plate member 16 is directed in the front and rear direction, the insertion body 5 formed in a plane cross shape is therefore for inserting the drift pin 17 The holes 16 b are arranged so as to be directed in the lateral, front, rear, left, and right directions of the wooden column 4.

  Further, the insertion body 5 is provided with four legs 16a by two legs 16a formed on each of the plate members 16 respectively, and therefore, four lower end joint parts 16c are provided. Therefore, as shown in FIG. 5, four slits 15 are formed in the flat plate material forming the ceiling wall 3e of the pedestal 3.

  Each slit 15 is cut at the width dimension of the lower end joint 16c from the center position of each side defining the periphery of the ceiling wall 3e to the center of the ceiling wall 3e, thereby the periphery of the ceiling wall 3e It is formed in part 3h. The ceiling wall 3e is, except for the position of the opening 6 in the front, avoiding the center portion which is susceptible to out-of-plane deformation, the peripheral portion 3h rigidly welded to the left and right side wall portions 3b and 3c and the rear wall portion 3d. The slits 15 are formed, and the rigidity of the ceiling wall 3 e itself and the support strength against the force acting on the plug 5 connected to the wooden post 4 are highly secured.

  At the lower edge of the ceiling wall 3e facing the lower surface 3g of the ceiling wall 3e, the lower end joint 16c of the plate member 16 which is the insertion body 5 is joined to the ceiling wall 3e by the penetration welding W with little overfill. The groove 15a is formed. By inserting the joining lower end portion 16c of the insertion body 5 into the slit 15 in which the groove 15a is formed and joining by penetration welding W, as shown in FIG. 8, the central portion of the ceiling wall 3e is avoided. In the position, in other words, surrounding the central portion, the leg portion 16a is welded to the peripheral portion 3h.

  Next, the operation of the wooden column support 1 according to the present embodiment will be described. When manufacturing the pedestal 1, first, a flat plate member constituting the rear wall portion 3 d is welded to a U-shaped member constituting the bottom wall portion 3 a and the pair of left and right side wall portions 3 b and 3 c of the pedestal 3 Join. Further, a pair of plate members 16 is assembled in a cruciform shape to form the insertion body 5.

  Then, the lower end joint portion 5c of the insertion body 5 is inserted into the slit 15 having the groove 15a of the flat plate material constituting the ceiling wall 3e, and the lower surface 3g of the ceiling wall 3e is along the groove 15a. Penetration welding W is performed to join the plug body 5 to the ceiling wall 3e.

  Thereafter, the lower surface 3g of the ceiling wall 3e to which the insertion body 5 is joined is welded to the upper portion of the left and right side wall portions 3b and 3c and the rear wall 3d. As a result, the wooden column pedestal 1 in which the inserting body 5 is provided on the hollow box-shaped pedestal 3 having the opening 6 formed on the front side is completed.

  In the pillar base 1 for wooden columns according to the present embodiment, the lower end joint portion of the insertion body 5, that is, the lower end joint portion 16c of the leg portion 16a of the plate member 16 has the lower edge thereof the lower surface 3g of the ceiling wall 3e The hollow box-shaped base body 3 is surrounded by the wall portions 3a to 3e of the ceiling wall portion and the like because it is formed with the dimension H that fits within the thickness of the ceiling wall portion 3e so as to be substantially flush. Because the insertion body 5 does not protrude and there is no protrusion, the hollow internal space S inside the pedestal 3 is widely used to the last position of the walls 3a to 3e. Can.

  At this time, since the locking projection 16e divides the lower end joint portion 16c of the leg portion 16a and is locked to the upper surface 3f of the ceiling wall 3e, the locking projection 16e is positioned, and the lower end joint portion 16c is positioned. The lower end of the plug 5 can be made flush with the lower surface 3g of the ceiling wall 3e to reliably prevent the insertion body 5 from projecting into the internal space S of the pedestal 3.

  The lower end joint portion 16c of the insertion body 5 is formed with a dimension H which does not protrude from the ceiling wall 3e, and when inserted into the slit 15 and welded and joined, the lower end joint 16c faces the lower surface 3g of the ceiling wall 3e. The hollow internal space S inside the base body 3 can be widely secured because it is joined by the penetration welding W with little overfill at the groove 15a formed at the edge.

  When weld joint between the plug body 5 and the ceiling wall 3e is performed on the upper surface 3f of the ceiling wall 3e, when installing the wooden column 4 on the ceiling wall 3e, removal of welding surplus or the lower surface of the wooden column 4 In the present embodiment, since welding of the plug body 5 and the ceiling wall 3e is performed on the lower surface 3g of the ceiling wall 3e, the upper surface of the ceiling wall 3e is required. 3f can be maintained on a flat surface, and the wooden column 4 can be installed easily and properly.

  In the construction using the wooden column support 1 according to the present embodiment, the anchor bolt 8 projecting upward from the foundation 2 is inserted into the hole 9 of the bottom wall 3 a of the pedestal 3 to mount the pedestal The bottom wall 3 a of the body 3 is placed on the foundation 2.

  Next, the wood beam 7 as a base is butted to the pedestal 3 from either the left or right (right in FIG. 1) and the rear two, and the hollow internal space S of the pedestal 3 in the hollow box shape Then, in a work from the front opening 6, the wood beam 7 in two directions is temporarily tightened by the bolt 12 via the spacer 14 on the rear wall 3 d and the right side wall 3 c. Before and after the temporary tightening of the bolt 12, the nut 19 is inserted inward of the pedestal 3 by the operation from the front opening 6 in the internal space S of the pedestal 3 of the hollow box shape. Temporarily tighten to 8.

  Next, the wooden column 4 is erected from above in the column height direction in the insert 5 provided upright on the pedestal 3, and the insert 5 is inserted into the column base 4 a of the wooden column 4. In this manner, when the positioning of the wooden column 4 and the wooden beam 7 of the base and the pedestal 3 is determined, the gap between the anchor bolt 8 and the hole 9 caused by the positional deviation between them is closed. A conventionally known eccentric ring part 20 is mounted.

  Thereafter, in the hollow internal space S of the base 3 in the form of a hollow box, the nut 19 is fully tightened to the anchor bolt 8 by work from the front opening 6, and the above bolt 12 is fully tightened to the wood beam 7. Do. As a result, the wooden column support 1 according to the present embodiment is joined and fixed on the foundation 2 via the anchor bolt 8, and at the same time, the positions of the wooden beam 7 and the wooden column 4 are determined.

  As described above, since there is no protrusion in the internal space S of the pedestal 3 as described above, the wooden column support 1 according to the present embodiment is a nut for the anchor bolt 8 implemented from the front opening 6 The fastening work of 19 and the fastening work of the bolt 12 for connecting the wood beam 7 can be smoothly performed, and the base body 3 can be efficiently installed on the foundation 2 without any trouble, and the installation workability is remarkably improved. Can be improved.

  After that, the pedestal 3 is provided in an arrangement in which the remaining wood beams 7 abut on the left side and the front side.

  Next, the drift pin 17 is inserted into the wooden column 4 through the pin hole and is inserted into the hole 16b of the insertion body 5, thereby connecting the wooden column 4 with the wooden column support 1. As described above, the wooden column 4 is supported by the wooden column support 1.

  The above-described installation procedure is an example, and installation may be performed according to any procedure. For example, in a working process in a pre-cut factory for processing pin holes of the drift pins 17 into the wooden columns 4, the wooden column support 1 according to the present embodiment is connected to the wooden columns 4 in advance. The attached wooden pillar 4 may be carried to the site and built at a predetermined position on the foundation 2.

  In a building using the wooden column support 1 according to the present embodiment, the pulling force acting on the wooden column 4 is pulled upward to the insertion body 5 on the pedestal 3 through the drift pin 17. Act as a force. The pull-out force can be supported by the plate member 16 which is the insertion body 5, in particular, by the leg portion 16a which is narrowly formed by the recess 16d and is rich in tensile deformation ability in the height direction of the wooden column 4. It is possible to reduce the burden on the wooden column 4 and improve the structural performance. On the other hand, the pressing force acting on the wooden pillar 4 can be sufficiently supported by the rigid pedestal 3.

  Moreover, the slit 15 which inserts the insertion body 5 connected with the wooden pillar 4 and joins this to the base body 3 avoids the center part of the ceiling wall part 3e, and forms in the peripheral part 3h of the ceiling wall part 3e Since the peripheral portion 3h is a rigid portion joined to the pair of left and right side wall portions 3b and 3c and the rear wall portion 3d of the base body 3, the plug-in body 5 is a ceiling wall susceptible to out-of-plane deformation The plug 5 can be fixed and supported on the pedestal 3 with high strength compared to the case of joining to the central portion of the portion 3e, whereby the pullout force acting from the wooden pillar 4 is sufficiently loaded and supported can do.

  Since the insertion body 5 is formed in a flat cross shape, and thereby the hole 16b through which the drift pin 17 is inserted is formed to be directed to the lateral, front, rear, left and right of the wooden column 4, the drift relative to the wooden column 4 A large number of pins 17 can be inserted from four directions to connect the wooden column 4 and the insertion body 5, and the wooden column 4 can be attached to the wooden column support 1 with high bonding strength.

  In the planar cross-shaped plug-in body 5, two plate members 16 in which the vertical slits 18 are respectively formed are fitted to each other from the upper and lower direction, and one slit plate 18 is used to connect the other plate Since the narrow portion 18a for holding the material 16 and the wide portion 18b for allowing the drift pin 17 to move in the lateral direction of the wooden column 4 are formed, the plate members 16 are integrated in the narrow portion 18a. The wide portion 18 b functions not only to secure the property but also to the wooden column 4 to relieve the tensile stress which may occur in the lateral direction perpendicular to the column height direction.

  In detail, in the general part where the fiber direction is along the height direction (longitudinal direction), the wood column 4 exerts the intended strength against the tensile force acting in the fiber direction, but “wooden” of the wood Since tensile force acts in the direction perpendicular to the fiber direction at portions such as nodes and nodes, which may cause breakage, it is preferable to reduce the tensile stress in the direction orthogonal to the fiber direction, in particular, It is required to reduce the influence of such tensile stress around the drift pin 17.

  The wide portion 18 b is formed by widening the notches 18 formed in the vertical direction in the plate member 16 inserted in the column height direction of the wooden column 4, whereby the holes 16 b on both sides of the notches 18 are formed. Since the drift pin 17 to be inserted is allowed to move in the lateral direction of the wooden column 4, that is, in the lateral direction orthogonal to the height direction (fiber direction) of the wooden column 4, the fiber direction orthogonal to the wooden column 4 is orthogonal. It is possible to prevent the breakage of the wooden column 4 by relieving the tensile stress in the direction.

  In the pillar base 1 for wooden columns according to the present embodiment, although the case where the insertion body 5 is formed into a plane cross shape from the pair of plate members 16 has been described, the insertion body 5 Even if it is composed of a sheet of plate material 16, or the slit 15 is not formed at a position corresponding to the opening 6 on the front side, a pair of left and right side wall portions 3b and 3c and a rear wall portion to which the ceiling wall 3e is joined The slits 15 may be formed at three locations corresponding to 3 d, and the insertion body 5 may be used in the form of a flat convex shape in which the lower end joint portion 16 c is inserted into the slits 15.
