JP 2003-119903 A (all pages)

  By the way, in order to insert the coupling pin or the bolt, as a matter of course, it is necessary to previously form an insertion hole (a lower hole) in both the lower end portion of the column member and the insertion portion of the connecting member. However, if there is a shift in the position of these insertion holes (lower holes), there arises a problem that the connecting pin or the like cannot be penetrated.

  In addition, the number and arrangement of the connecting pins need to be changed as appropriate according to the load acting on the pillars, etc., and the number of pillars used in houses etc. is enormous. It is very laborious and labor intensive to drill a hole.

  Such problems are not limited to the connection structure between the foundation and the pillar material, but the connection structure between the foundation and the pillar, the connection structure between the pillar material and the pillar material, the connection structure between the pillar material and the beam material, and the wall. This is a problem that is commonly applied to a connection structure between structural members such as a connection structure between a beam and a beam.

  Then, this invention is a connection structure of the structural member with favorable workability, Comprising: It aims at providing the connection structure of the structural member with favorable productivity of the various members which comprise the said connection structure.

  The present invention created in order to solve such problems includes a first structural member, a second structural member connected to the first structural member, the first structural member, and the second structural member. A connecting member interposed at a boundary portion between the second structural member, a slit is formed at an end of the second structural member, and the connecting member A fixing portion fixed to the first structural member and an insertion portion inserted into the slit, and the insertion portion of the connecting member and the end portion of the second structural member are It is characterized by being joined by a drilling tapping screw threaded from the surface of the second structural member.

  Such a connection structure of the structural members is configured to join the end portion of the second structural member and the insertion portion of the connection member using a drilling tapping screw that does not require a pilot hole. The productivity of the second structural member and the connecting member is improved by the amount that is favorable and does not require the preparation of the lower hole. In addition, in the conventional structure member connection structure in which the end portion of the second structural member and the insertion portion of the connection member are fixed with a connection pin or bolt, the same number of pilot holes as the number of connection pins and the like are drilled in advance. Since the number of connecting pins and the like cannot be changed after drilling the pilot hole, the drilling hole is not required according to the connection structure of the structural members according to the present invention. It is possible to arbitrarily set the number of tapping screws.

  In the connecting structure for structural members according to the present invention, the connecting member may be made of an aluminum alloy, and further, the connecting member may be made of an extruded shape made of an aluminum alloy. In this way, the productivity of the connecting member is further improved.

  In the connecting structure of the structural members according to the present invention, the first structural member is a base installed along the upper surface of the foundation, and the second structural member is a pillar material or a brace, and the connecting member The fixed portion may be fixed to the upper surface of the base using anchor bolts planted on the foundation.

  If it does in this way, the foundation which is the 1st structural member, and the pillar material which is the 2nd structural member can be connected easily and certainly, and also using the anchor bolt in which the connecting member was planted on the foundation Since it is fixed, the pulling force acting on the connecting member is reliably transmitted to the foundation.

  In the connecting structure of structural members according to the present invention, the first structural member is a base, the second structural member is a pillar material or a brace, and the base is installed along the upper surface of the foundation. A base lower layer portion and a base upper layer portion fixed to the upper surface of the base lower layer portion, and the fixing portion of the connecting member is attached to the base lower layer portion using anchor bolts planted on the foundation. It may be fixed.

  If it does in this way, the foundation which is the 1st structural member, and the pillar material which is the 2nd structural member can be connected easily and certainly, and also using the anchor bolt in which the connecting member was planted on the foundation Since it is fixed, the pulling force acting on the connecting member is reliably transmitted to the foundation.

  In the connecting structure of structural members according to the present invention, the base may be one in which the lower layer portion is made of an aluminum alloy hollow extruded shape and the upper layer portion is made of wood.

  If it does in this way, it will become possible to hit a nail with respect to a foundation upper layer part. That is, it becomes possible to fix the pillar material, the structural plywood, and the like to the base in the same manner as a conventional wooden house. In addition, since the lower layer of the foundation is made of an extruded shape made of an aluminum alloy, the foundation of an aluminum alloy foundation such as “no damage from white ants” or “no corrosion or dimensional change due to moisture” In addition, the weight of the entire foundation is still lighter than the conventional wooden foundation, so its transportation and handling at the construction site are also good.

  In the structure for connecting structural members according to the present invention, a recess is formed along the longitudinal direction at the center in the width direction of the base lower layer portion, and the fixing portion of the connection member protrudes from the bottom surface of the recess. It may be fixed to the bottom surface of the recess using the anchor bolt.

  If it does in this way, it will become possible to suppress the thickness of a base upper layer part to the required minimum, and it will become possible to attain weight reduction of the whole foundation by extension. In other words, considering the installation of pillars etc. on the upper surface of the foundation upper layer part, it is desirable that the upper end of the anchor bolt does not protrude from the upper surface of the foundation upper layer part. In order to achieve the above, it is necessary to make the thickness of the upper layer of the base more than the protruding length from the insertion hole of the anchor bolt. Only the thickness of the base upper layer can be reduced. And since the ratio of the wood which occupies for the whole foundation becomes small by the part which thickness of a foundation upper layer part becomes small, as a result, it becomes possible to achieve weight reduction of the whole foundation. Further, there is an advantage that positioning of the connecting member becomes easy.

  In the connecting structure of the structural members according to the present invention, a pair of partition walls facing each other with the anchor bolt interposed therebetween are formed inside the foundation lower layer portion and below the bottom surface of the recess. Also good.

  In this way, even when a vertical load is applied to the connecting member, deformation that occurs on the bottom surface of the recess is reduced.

  In the connection structure of the structural member according to the present invention, the fixing portion of the connection member has an insertion hole into which the anchor bolt can be inserted, and the insertion portion of the connection member is positioned above the insertion hole. It may have an opening at the part to be.

  If it does in this way, since the insertion part of a connection member will be located just above an anchor bolt, balance is good.

  According to the connection structure of the structural member which concerns on this invention, while the construction property improves, the productivity of the various members which comprise the said connection structure improves.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the accompanying drawings.

(First embodiment)
FIG. 1 shows a structural member connection structure according to a first embodiment in which a pillar material 20 as a second structural member is connected to a base 10 as a first structural member, and a large pull 30 is connected to the base 10. This is a large-scale connection structure. Here, a connecting member 40 is interposed at a boundary portion between the base 10 and the column member 20, and a large pull connecting member 50 is interposed at a boundary portion between the base 10 and the large pull 30. .

(Base)
The foundation 10 as the first structural member includes a foundation lower layer portion 10A installed along the upper surface of the foundation K, and a foundation upper layer portion 10B fixed to the upper surface of the foundation lower layer portion 10A. In the present embodiment, the base 10 is installed on the upper surfaces of a plurality of spacers S, S,... Arranged at predetermined intervals on the upper surface of the foundation K.

  As shown in FIG. 2, the base lower layer portion 10 </ b> A is made of an aluminum alloy hollow extruded shape, and a concave portion 17 is formed along the longitudinal direction at the center in the width direction of the upper portion. The structure of the base lower layer portion 10A will be described in more detail. The base lower layer portion 10A includes a lower wall 11, a pair of left and right side walls 12 and 12 suspended from the lower wall 11, and the side walls 12 and 12. A pair of left and right partition walls 13, 13 suspended from the lower wall 11, a bottom wall 14 connecting the upper ends of the partition walls 13, 13, and a pair of left and right walls suspended from the end of the bottom wall 14 Inner walls 15 and 15 and a pair of left and right upper walls 16 and 16 that connect each inner wall 15 and each side wall 12 are provided, and a recess 17 is formed by the bottom wall 14 and the pair of inner walls 15 and 15. .

As shown in FIGS. 3A and 3B, the lower wall 11 has an insertion hole 11a formed at the center in the width direction. The anchor bolt B planted in the foundation K is inserted through the insertion hole 11a.
Each side wall 12 is suspended from the edge of the lower wall 11 at a position slightly inside. That is, the edge 11 b of the lower wall 11 protrudes laterally from the lower end of each side wall 12. In other words, it can be said that an overhanging portion is formed on the side surface of the base lower layer portion 10A so as to project toward the side.
The partition walls 13, 13 are formed inside the base lower layer portion 10A and below the bottom surface of the recess 17, and face each other with the insertion hole 11a of the lower wall 11 and the insertion hole 14a of the bottom wall 14 interposed therebetween. ing.
The bottom wall 14 has an edge projecting outward from the partition wall 13, and an insertion hole 14 a through which the anchor bolt B is inserted is formed in the center in the width direction. That is, the insertion hole 14 a is formed in the bottom surface of the recess 17.
The inner walls 15, 15 are opposed to each other with the insertion hole 14 a of the bottom wall 14 interposed therebetween. The separation distance between the inner walls 15, 15 (that is, the width of the recess 17) is slightly larger than the width of the fixing portion 41 of the connecting member 40 described later, and the height of each inner wall 15 is greater than the thickness of the fixing portion 41. Is also getting bigger.

  As shown in FIG. 2, the base upper layer portion 10B is made of wood set to the same width as the upper surface of the base lower layer portion 10A, and a plurality of drilling tapping screws 19, 19 screwed from the upper surface side. Are fixed to the upper surface (left and right upper walls 16, 16) of the base lower layer 10A. Note that the thickness of the base upper layer portion 10B is a minimum thickness necessary for driving a nail for fixing the structural plywood 60 (see FIG. 1) and a nail for fixing the spacer 70 (see FIG. 1). If it is. Further, the base lower layer portion 10A and the base upper layer portion 10B are previously integrated in a factory or the like before they are installed on the upper surface of the foundation K (see FIG. 1).

  In this embodiment, the drilling tapping screws 19 are arranged in two rows along the longitudinal direction of the base upper layer portion 10B, and in each row, the interval between the drilling tapping screws 19 adjacent in the longitudinal direction is constant. ing. In this way, for example, when the structural plywood 60 (see FIG. 1) or the like is fixed to the side surface of the base upper layer portion 10B, the position of the drilling tapping screw 19 cannot be directly observed. Since the plurality of drilling tapping screws 19, 19,... Are arranged at equal intervals in the longitudinal direction, the position of the drilling tapping screw 19 is grasped by using the column material 20 (see FIG. 1) as a reference. As a result, it is possible to drive the nail while avoiding the drilling tapping screw 19. In addition, when the drilling tapping screw 19 is used, the base lower layer portion 10A and the base upper layer portion 10B are firmly coupled to each other, and the lower hole is not required, so that the base 10 can be easily manufactured.

  Further, in the base upper layer portion 10B, an opening 18 is formed in a portion located above the insertion holes 11a and 14a of the base lower layer portion 10A. The opening 18 may have any shape that allows at least the nut N to be screwed into the anchor bolt B to be inserted. In the present embodiment, the opening 18 has a rectangular shape, and as shown in FIG. The fixed part 41 is formed in a size that can be inserted. In addition, although illustration is abbreviate | omitted, in the foundation K, the some anchor bolt B (refer Fig.3 (a)) is planted at predetermined intervals, and it corresponds to this in the base upper layer part 10B. Also, a plurality of openings 18 are formed at predetermined intervals.

  In addition, as shown in FIG. 3A, since the pillar material 20 and the like are installed on the upper surface of the base upper layer portion 10B, the depth of the concave portion 17 of the base lower layer portion 10A and the thickness of the base upper layer portion 10B are as follows. It is desirable to set the size so that the upper end of the anchor bolt B does not protrude from the upper surface of the base upper layer portion 10B. Although it is possible to make the upper surface of the base lower layer portion 10A flush without providing the recess 17, the thickness of the base upper layer portion 10B is made larger than that shown in FIG. 3 (a). Since it is necessary to enlarge, after all, the ratio of the wood which occupies for the base 10 becomes large, and the weight of the base 10 whole will increase. On the other hand, when the concave portion 17 is provided in the base lower layer portion 10 </ b> A, the thickness of the base upper layer portion 10 </ b> B can be reduced by the depth of the concave portion 17. In other words, when the recess 17 is provided in the base lower layer portion 10A, the proportion of the wood in the base 10 is reduced by the thickness of the base upper layer portion 10B, and the weight of the entire base 10 is reduced.

  Moreover, the base 10 is fixed along the upper surface of the foundation K using the anchor bolt B, as shown in FIG. In order to fix the base 10 along the upper surface of the foundation K, the base 10 is installed on the upper surfaces of the spacers S, S,... While the anchor bolts B are inserted through the insertion holes 11a, 14a of the base lower layer portion 10A. What is necessary is just to screw the nut N in the thread part of the anchor bolt B which protruded from the bottom face of the recessed part 17 of 10 A of parts. In addition, since the pair of partition walls 13 and 13 that are opposed to each other with the insertion holes 11a and 14a interposed therebetween are formed inside the base lower layer portion 10A and below the bottom surface of the concave portion 17, the nut N is firmly tightened. Even so, the deformation occurring on the bottom surface of the recess 17 is very small.

  And according to such a base 10, it becomes possible to hit a nail on the upper surface or the side of the base upper layer portion 10B. That is, as shown in FIG. 1, the structural plywood 60, the stud 70, and the like can be fixed to the base 10 in the same manner as a conventional wooden house.

  In addition, since the base 10 is made of an extruded material made of an aluminum alloy, the base 10 is made of aluminum such as “not subject to white ant corrosion” or “no corrosion or dimensional change due to moisture”. It also has the advantages of an alloy base, and further, the weight of the base 10 as a whole is still lighter than that of a conventional wooden base.

(Column material)
As shown in FIG. 4, the column member 20 as the second structural member has a slit 21 formed at the lower end thereof. The slit 21 is formed along a vertical plane and has a dimension that allows the insertion portion 42 of the connecting member 40 to be inserted.

(Connecting member)
The connecting member 40 is made of an extruded product made of aluminum alloy having an inverted T-shaped cross section, and includes a fixing portion 41 fixed to the base 10 and an insertion portion 42 inserted into the slit 21 of the column member 20. Yes.

  The fixing portion 41 has a rectangular shape, and is inserted into the concave portion 17 of the base lower layer portion 10A through the opening 18 of the base upper layer portion 10B. In the center of the fixing portion 41, an insertion hole 41a into which the anchor bolt B (see FIG. 3A) can be inserted is formed.

  The insertion part 42 is erected on the upper surface of the fixing part 41, and an opening part 42 a is formed at a position located above the insertion hole 41 a of the fixing part 41. That is, the insertion portion 42 includes a pair of plate-like leg portions 42b and 42b that are provided side by side with the insertion hole 41a of the fixing portion 41, and a plate-like head portion 42c that connects the upper ends of the leg portions 42b and 42b. And has a gate shape as a whole.

  In order to manufacture the connecting member 40, as shown in FIG. 5, the extruded shape A made of aluminum alloy having an inverted T-shaped cross section is cut to an appropriate length, and the lower portion of the vertical plate A2 is rectangular. It is only necessary to form the opening 42a by forming the opening 42a, and to form a through hole 41a by drilling a through-hole communicating with the opening 42a in the bottom plate A1. When the connecting member 40 is formed by processing the extruded shape A made of aluminum alloy in this way, the productivity of the connecting member 40 is improved. The connecting member 40 may be formed of an aluminum alloy casting.

  Moreover, the connection member 40 is fixed to the base 10 using the anchor bolt B, as shown in FIG. In order to fix the connecting member 40 to the base 10, as shown in FIG. 4, the fixing portion 41 of the connecting member 40 is inserted into the recess 17 of the base lower layer portion 10A from the opening 18 of the base upper layer portion 10B, and then fixed. The fixing portion 41 is placed on the bottom surface of the concave portion 17 while the threaded portion of the anchor bolt B is inserted into the insertion hole 41a of the portion 41, and then the anchor protruding from the bottom surface of the concave portion 17 as shown in FIG. A nut N may be screwed into the threaded portion of the bolt B.

(Connection structure of structural members)
As shown in FIG. 1, the column member 20 as the second structural member is connected to the base 10 as the first structural member via a connecting member 40. Further, the lower end portion of the column member 20 and the insertion portion 42 of the connecting member 40 are formed from the side surface (surface) parallel to the slit 21 (see FIG. 4) of the column member 20 and the head portion 42c (see FIG. 4) of the insertion portion 42. Are joined by a plurality of drilling tapping screws 22, 22 screwed through. The number of drilling tapping screws 22 may be appropriately changed according to the magnitude of the load acting on the column member 20, but is approximately in the range of two to seven. Although not shown, even when three or more drilling tapping screws 22 are used, each drilling tapping screw 22 is passed through the head portion 42c of the insertion portion 42 (see FIG. 4). The plurality of drilling tapping screws 22 are arranged in one horizontal row or two rows.

  And according to the connection structure of the structural member which uses the connection member 40, the base 10 which is a 1st structural member, and the pillar material 20 which is a 2nd structural member can be connected easily and reliably, Furthermore, a connection member Since 40 is fixed using the anchor bolt B planted on the foundation K, the pulling force acting on the connecting member 40 is reliably transmitted to the foundation K.

  Moreover, since the connection structure of such a structural member is the structure which joins the lower end part of the pillar material 20, and the insertion part 42 of the connection member 40 using the drilling tapping screw 22 which does not require a pilot hole, it is workability. Is improved, and the productivity of the column member 20 and the connecting member 40 is improved by the amount that does not require the preparation of the lower hole. Further, in the conventional structure member connecting structure in which the lower end portion of the column member 20 and the insertion portion 42 of the connecting member 40 are fixed with a connecting pin or a bolt, the same number of pilot holes as the number of connecting pins or the like are previously drilled. However, the number of connecting pins and the like cannot be changed after drilling the pilot hole. However, according to the connecting structure of the structural members described above, the pilot hole is not required. The number of 22 can be arbitrarily set.

  As shown in FIG. 3A, since the pair of partition walls 13 and 13 are formed inside the base lower layer portion 10A and below the bottom surface of the recess 17, the connecting member is interposed via the column member 20. Even if a large load is applied to 40, the deformation generated on the bottom surface of the recess 17 is very small.
