Description

  The present invention relates to a connection structure between a base made of an extruded shape made of an aluminum alloy and a wooden pillar.

  As this type of connection structure, a structure in which a base and a pillar material are connected via a connection hardware provided on the upper surface of the base is known (see, for example, Patent Document 1 to Patent Document 3).

JP2003-119903A (FIG. 2) Japanese Patent Laying-Open No. 2003-160978 (FIG. 5) Japanese Patent Laying-Open No. 2004-245043 (FIG. 7)

  However, in such a conventional connection structure, it is necessary to fix the connection hardware to the base by some means before installing the pillar material, so that the work on the construction site is complicated accordingly. There is a problem.

  Therefore, the present invention is a connection structure between a base made of an aluminum alloy extruded profile and a wooden pillar, and the foundation and the pillar can be easily and reliably built into the foundation. It is an object to provide a connection structure.

  The present invention for solving such a problem is a joining structure of a base made of a hollow aluminum alloy extruded profile and a wooden pillar, and the lower end of the pillar is on the upper surface of the foundation. It is characterized by being inserted into the inside of the base from the formed opening.

  According to such a connection structure between the base and the pillar, the positioning of the pillar can be achieved by simply inserting the lower end of the pillar into the opening provided on the upper surface of the base and fitting the lower end into the interior of the base. Since the temporary fixing is completed, the pillar material can be easily and surely built on the foundation. Moreover, according to this connection structure, since the lower end portion of the column material enters the inside of the base, the lower end portion of the column material is restrained by the base, and as a result, even in the temporarily fixed state, Inclination or the like hardly occurs. In addition, since it is not necessary to provide a connection hardware between the upper surface of the base and the lower end portion of the pillar material, the number of parts can be reduced, and as a result, the cost can be reduced. In addition, the base is made of extruded aluminum alloy that is light in strength, so it is easy to handle on the site, and is not affected by white ants. Even if it does, it does not decay. In addition, the extruded profile has high manufacturing accuracy and does not change over time in cross-sectional dimensions, and therefore does not cause harmful distortion in the connecting portion with the column. In addition, it is lighter and more workable than a conventional wooden base.

  In the present invention, a fixing tool penetrating the lower end portion of the pillar material may be driven from the side surface of the base. In this way, the pulling strength of the column material is improved, so that a more robust connection structure can be provided.

  Further, in the present invention, a pair of partition walls are integrally extruded along the longitudinal direction of the base inside the base, and the column member is provided to protrude from the column main body and the lower end surface of the column main body. The tenon may be fitted between the partition walls in a state in which the lower end surface of the column main body is in contact with the upper surface of the base. In other words, three hollow portions may be formed in the base by a pair of partition walls arranged inside the base, and a columnar boss may be inserted into the hollow portion located at the center thereof. Thus, if a partition wall is provided in the inside of a base, it will become a cross-sectional structure strong against a vertical load. In addition, because the bottom is provided with a tenon at the lower end of the pillar material, and this teno is fitted between the two partition walls, the partition wall does not get in the way when building the pillar material, and it is placed on the top surface of the base. The positioning and temporary fixing of the column members are completed simply by inserting the tenon into the provided opening and fitting the tenon between the pair of partition walls inside the base. It should be noted that in order to provide a tenon at the lower end of the pillar material, it is necessary to process the end of the wood material. Even when wood is pre-cut at a factory, it is preferable because existing factory equipment corresponding to the conventional frame construction method can be used as it is.

  According to the connection structure between the foundation and the pillar material according to the present invention, the pillar material can be easily and reliably built into the foundation.

As shown in FIG. 3B, the opening 12b is formed in the center of the base 10 in the short direction (left and right in FIG. 3B), and the central hollow portion 10B (see FIG. 3). 3 (see (a)). In addition, the opening part 12b is shape | molded by the rectangle in this embodiment, The lateral width b is equal to the separation distance of the partition walls 14 and 14. FIG.

  As shown in FIG. 4, a pair of pin insertion holes 13 a and 13 a (see FIG. 4) are formed in the side wall 13 side by side in accordance with the position where the column member 20 is connected. In addition, the fixing tool 30 is inserted in each pin insertion hole 13a.

  As shown in FIG. 3A, the partition walls 14, 14 partition the space formed by the lower wall 11, the upper wall 12, and the side walls 13, 13 (that is, the internal space of the base 10). It is arranged along the longitudinal direction of the base 10 (the direction perpendicular to the paper surface in FIG. 3 (a)), and faces the bolt insertion hole 11a of the lower wall 11 and the bolt insertion hole 12a of the upper wall 12 therebetween. Yes. The partition wall 14 is formed with pin insertion holes (not shown) in accordance with the positions of the pin insertion holes 13a, 13a (see FIG. 4) of the side wall 13. Further, the partition walls 14 and 14 are integrally extruded together with the lower wall 11, the upper wall 12 and the side wall 13.

  Here, the base 10 is fixed to the foundation K by screwing the nuts N into the anchor bolts B inserted through the bolt insertion holes 11a and 12a. Note that two large and small washers W1 and W2 are interposed between the top surface of the base 10 and the nut N. Here, the large washer W1 is formed in a size and shape that can block the bolt insertion hole 12a, and is disposed so as to straddle the pair of partition walls 14,14.

  As shown in FIG. 4, the column member 20 includes a long column main body 21 and a side wall 22 protruding from the lower end surface of the column main body 21.

  In this embodiment, the column main body 21 has a square cross section, and the length of one side thereof is equal to the horizontal width of the base 10 (see FIG. 3A).

Further, the lateral width b 'of the side wall 22 is shorter than the length A of one side of the column main body 21, and is substantially equal to the lateral width b of the opening 12b. In other words, in the present embodiment, the cross-sectional dimension / cross-sectional shape of the tenon 22 is substantially equal to the shape / dimension of the opening 12b. If it does in this way, since the tenon 22 will fit in the opening part 12b without gap, when the pillar material 20 stands upright on the base 10, the positioning of the base 10 in the longitudinal direction becomes easy. The horizontal width b ′ of the tenon 22 is equal to the separation distance between the partition walls 14 and 14, and when the tenon 22 is inserted into the opening 12b, the tenon 22 is separated from the partition wall as shown in FIG. 14 and 14 enter without gaps.

  In addition, the height c ′ of the tenon 22 is slightly smaller than the height (depth) of the hollow portion 10 </ b> B. In this way, when the tenon 22 is fitted into the hollow portion 10B, a gap is secured between the lower end surface of the tenon 22 and the lower wall 11 of the base 10, and as a result, the lower end surface of the column main body 21 is the base. 10 is surely brought into contact with the upper surface of 10.

  In addition, what is necessary is just to cut the material end of a wooden square material by a suitable means in order to provide the tenon 22 in the lower end part of the column material 20. Here, if it is processing to the extent that the hozo 22 is provided, it is easily accepted by carpenters who are good at conventional shaft construction methods and prefabrication construction methods, and even when wood is pre-cut at the factory, the conventional shaft construction method. It is preferable because existing factory equipment corresponding to the above can be used as it is.

  In the present embodiment, the fixing tool 30 shown in FIG. 4 includes a drift pin having the same length as the lateral width of the base 10, and includes a pin insertion hole 13 a in the side wall 13, a pin insertion hole (not shown) in the partition wall 14, 22 is inserted into the pin insertion hole 22a. The fixing tool 30 is inserted into the hollow portion 10B of the base 10 in the hollow portion 10B (see (b) of FIG. 3) of the pillar material 20 and then inserted into the other through the pin insertion hole 13a on one side wall 13 of the base 10. It is driven toward the pin insertion hole 13a of the side wall 13.

  As shown in FIG. 4, the large fork 40 is made of a hollow aluminum alloy extruded shape, and is fixed to the side surface of the base 10 via a bracket 50 protruding from the side surface of the base 10. Here, the end of the lower wall 41 of the large fork 40 is cut out in accordance with the protruding portion of the bracket 50, and the end of the large fork 40 is covered with the bracket 50 as shown in FIG. The bracket 50 is fixed.

  The bracket 50 is obtained by cutting an extruded shape made of an aluminum alloy with an appropriate length, and is fixed to a side surface of the base 10 by a drilling tapping screw D. More specifically, referring to FIG. 4, the bracket 50 includes a contact plate 51 fixed to the side surface of the base 10, and a pair of projecting plates 52 and 52 suspended from the contact plate 51. The projecting plates 52, 52 are provided with a connecting plate 53 provided so as to connect the tips of the projecting plates 52, 52. Here, the U-shaped section formed by the protruding plates 52 and 52 and the connecting plate 53 is formed in a size and shape that can be inserted into the inside of the large pull 40, and the end of the large pull 40 is formed. When covering the bracket 50, the outer surfaces of the protruding plates 52, 52 abut against the inner side surface of the large pull 40, and the upper ends of the protruding plates 52, 52 and the connecting plate 53 are in contact with the upper surface of the large pull 40. In the present embodiment, since the positions of the upper ends of the protruding plates 52 and 52 and the connecting plate 53 are lowered by the thickness of the large pull 40 from the upper end of the contact plate 51, the end of the large pull 40 Is covered with the bracket 50, the upper surface of the fork 40 and the upper surface of the base 10 are flush with each other.

Next, with reference to FIG. 4, the construction procedure of the connection structure according to the present embodiment will be described.
First, the base 10 is fixed to the foundation K. More specifically, after the spacers S are arranged on the upper surface of the foundation K at appropriate intervals, the base 10 is inserted into the bolt insertion holes 11a and 12a of the foundation 10 while the anchor bolts B protruding from the foundation K are inserted. After mounting the two large and small washers W1 and W2 on the anchor bolt B protruding from the top surface of the base 10 and screwing the nut N thereon, the base 10 is attached to the foundation K. Fixed.

  Next, the column member 20 is erected on the base 10. More specifically, in a state in which the column member 20 is substantially vertical, the tenon 22 formed at the lower end thereof is inserted into the opening 12b provided on the upper surface of the base 10, and the lower end surface of the column main body 21 is the base 10. When the tenon 22 is fitted into the base 10 until it comes into contact with the upper surface, the column 20 is erected on the base 10. In the present embodiment, since the size and shape of the opening 12b of the base 10 are formed such that the hoses 22 of the pillars 20 are just fitted, the hoso 22 is inserted into the openings 12b of the base 10 and a pair is formed. The positioning and temporary fixing of the column member 20 are completed simply by fitting between the partition walls 14 and 14. In the present embodiment, since the side wall 22 of the column member 20 is fitted between the two partition walls 14, 14, the partition walls 14, 14 become an obstacle when the column member 20 is built. There is no.

  Subsequently, the fixing tool 30 is driven through the pin insertion hole 13a of the one side wall 13 of the base 10, and penetrates into the pin insertion hole (not shown) of the partition wall 14 and the pin insertion hole 22a of the side wall 22, The tip is made to reach the pin insertion hole 13 a of the other side wall 13.

  Next, at the position where the large pull 40 is connected, the bracket 50 is applied to the side surface (side wall 13) of the base 10, and the drilling tapping screw D is driven into the contact plate 51 to fix the bracket 50 to the side surface of the base 10. . In the present embodiment, the fork 40 is connected to the base 10 so as to intersect with the column member 20, and therefore, when the bracket 50 is fixed to the side surface of the base 10, the pin insertion hole of the base 10 by the contact plate 51. 13a will be blocked. That is, the bracket 50 prevents the fixing tool 30 from coming out.

  Thereafter, the large pull 40 is dropped from above the bracket 50, the end of the large pull 40 is fitted into the bracket 50, and a drilling tapping screw (not shown) is driven from the side surface of the large pull 40 so as to penetrate the protruding plate of the bracket 50. Then, the end of the large pull 40 is fixed to the bracket 50.

  In addition, when constructing a floor set using the base 10 and the large fork 40, for example, in the case of a Western-style room, as shown in FIG. A joist 61 is disposed, and a base plywood 62 and a floor finishing material 63 may be laid on the upper surface of the joist 61. When constructing a Japanese-style room, as shown in FIG. 5 (b), the attachment position of the large pull 40 is lowered from that of FIG. The joist 61 may be disposed, and the base ply 62 and the tatami 64 may be laid on the joists 61 and the upper surface of the base 10. Lowering the position of the Japanese-style large fork 40 can make the upper surface of the tatami 64 and the upper surface of the floor finishing material 63 of the Western-style room flush with each other, which is suitable for building a barrier-free house. In FIG. 5, the bracket 50 (see FIG. 4) is not shown.

  And according to the connection structure comprised as mentioned above, the tenon 22 of the pillar material 20 is inserted in the opening part 12b provided in the upper surface of the base 10, and the tenon 22 is fitted inside the base 10 (hollow part 10B). As a result, the positioning and temporary fixing of the column member 20 are completed, so that the column member 20 can be easily and reliably built into the base 10. Moreover, according to this connection structure, since the tenon 22 of the column member 20 enters the hollow portion 10B of the base 10, the tenon 22 of the column member 20 is restrained by the base 10, and as a result, temporarily fixed. Even in this state, the column member 20 is unlikely to be inclined. Further, since there is no need to interpose a connection hardware between the upper surface of the base 10 and the lower end portion of the column member 20, the number of parts can be reduced, and as a result, the cost can be reduced. Become.

  Furthermore, since the base 10 uses an extruded aluminum alloy that is light in strength, it can be easily handled on site, and is not affected by white ants. It does not rot even if it faces. In addition, the extruded profile has high manufacturing accuracy and does not change over time in cross-sectional dimensions, so that no harmful distortion is caused in the connection portion with the column member 20. Moreover, since the partition walls 14 and 14 are provided in the base 10, the intensity | strength with respect to a vertical load is also large.

  Further, the pull-out strength of the pillar member 20 is improved by the fixing tool 30 penetrating the base 10 and the tenon 22 of the pillar member 20, so that it is possible to omit the hole down hardware and the like.

  Further, regarding the connection portion between the base 10 and the large pull 40, in this connection portion, the upper surface inside the large pull 40 abuts on the upper end surface of the bracket 50 (that is, the upper ends of the protruding plates 52 and 52). Since the downward movement of the pull 40 is restricted, the strength in the vertical direction is high, and the outer surface of the bracket 50 (that is, the outer side surface of the protruding plate 52) is in contact with the inner side surface of the large pull 40. Since the lateral movement of the large pull 40 is restricted, the strength against the horizontal load is high.

  In addition, in this embodiment, although the case where the large drawing 40 was connected to the position where the column material 20 is connected was illustrated, depending on a floor plan etc., the large drawing 40 can also be attached to another position.

It is a perspective view which shows the connection structure of the base and pillar material which concern on this embodiment.
