[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting metal fitting for building which is provided straddling a base and a pillar in a wooden building, and is used for joining the base and the pillar.

[0002]

2. Description of the Related Art Conventionally, when building a house or the like, a method of installing a pillar on a base and connecting and fixing the pillar to the base is as follows. A tenon is formed on the base, and a tenon hole is formed on the base side so as to fit the tenon, and the tenon of the pillar is fitted into the tenon hole of the base.

[0003]

However, according to the conventional fixing method, only the base and the column are joined and fixed by fitting the tenon of the column and the tenon hole of the base, and the joint strength is not sufficient. In other words, there is a risk that the pillars may be pulled out of the base against pitching caused by a direct type earthquake or the like. In addition, the processing of the tenon is very time-consuming. In order to solve such a problem, the applicant of the present invention has provided a connecting bracket body in which a fixing pin insertion hole penetrating the connecting rod is provided in the connecting rod and a seat plate is provided at one end of the connecting rod. There has been proposed an architectural connection fitting comprising a fixing pin inserted into the fixing pin insertion hole of the connection fitting main body (Japanese Utility Model Application No. 5-6985).
issue). According to this connection fitting, when connecting and fixing the column and the base, it is not necessary to provide a tenon on the column, and the joint strength between the column and the base is high and there is no possibility that the column is pulled out from the base. .

[0004] However, when the foundation and the column are to be connected using the above-mentioned architectural connection fitting, a pin hole is previously formed in the column at a position determined by the position of the fixing pin insertion hole of the connecting rod and the thickness of the base. Since, for example, if the thickness of the base is thinner than originally planned, a gap is created between the base and the pillar when the pillar and the connecting rod are fixed by the fixing pin, If the column is to be brought into close contact with the base, the position of the pin hole of the column and the position of the fixing pin insertion hole of the connecting rod are shifted, and the column cannot be fixed to the connecting rod. Further, if the thickness of the base is thicker than originally planned, the lower end of the pillar comes into contact with the base, and the positions of the pin holes of the pillar and the fixing pin insertion holes of the connecting rod are shifted, so that the pillar cannot be fixed to the connecting rod. Furthermore, if the position of the pin hole formed in the column is shifted from the beginning in the vertical direction, or if the lower end of the column is cut off in the process of processing the column, the same problem as described above occurs. And as a result of these problems, pillars and base materials processed with the wrong dimensions become unusable, so that these building materials are wasted, or otherwise it takes time to rework. There are drawbacks.

[0005] The above problems can be solved by preparing architectural fittings of various types of dimensions, but preparing multiple types of specifications whose usage frequency is not determined is also wasteful as described above. It is. In addition, there is also a disadvantage that in the above-mentioned connecting bracket, a tightening force between the column and the base is not obtained, and when the column or the base shrinks due to drying, a gap may be generated between the column and the base. Have.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and enables the base and the column to be closely contacted and connected regardless of the thickness of the base or the position of the pin hole of the column. It is an object of the present invention to provide an architectural connection fitting which does not cause a gap between its joints even when a column or a base contracts. That is, the architectural connection fitting of the present invention can be screwed to a connection rod having a fixed pin insertion hole formed at a predetermined position and a female screw or a male screw formed at an end, and a screw at an end of the connection rod. It comprises a pedestal having a male screw or a female screw, and a fixing pin inserted into the fixing pin insertion hole of the connecting rod.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. The drawings show one embodiment of the present invention, and FIG. 1 is a perspective view showing an example of a connecting metal fitting for construction of the present invention.

[0008] The architectural connection fitting 1 of the present invention comprises, for example, a connection rod 2, a pedestal 3 and a fixing pin 4 as shown in FIG. 1. The connecting rod 2 has a cylindrical shape, and fixed pin insertion holes 5a and 5b having a circular cross section and having a circular cross section perpendicular to the axis and perpendicular to each other at a position above the lower end by a predetermined length are adjacent to each other. And the fixing pin insertion hole 5
a, fixed pin insertion holes 5c, 5d similar to the fixed pin insertion holes 5a, 5b are formed above the fixed rod insertion holes 5a, 5b, and at the lower end of the connection rod 2 along the axis of the connection rod 2; A spiral female screw 6 is formed, and the diameter of the hollow portion of the connecting rod except for the female screw is larger than the maximum diameter of the spiral male screw 9 of the pedestal 3 described later. A notch 7 having a tapered shape is formed at the upper end of the connecting rod 2. The pedestal 3 is provided with a helical male screw 9 projecting upward and screwable to the helical female screw 6 at the center of a disc-shaped seat plate 8. The fixing pin 4 is a round rod having a diameter slightly smaller than the diameter of the fixing pin insertion hole 5 of the connecting rod 2 and having both ends formed in a tapered shape.

FIG. 2 to FIG. 4 are perspective views for explaining means for joining a column to a base using the connecting metal fitting for construction of the present invention. As shown in FIG. 2 (a), in order to join the column to the base using the connecting metal fitting 1 of the present invention, the mortise hole 14 and the fixing pin 4 into which the connecting rod 2 can be inserted into the column 13 in advance are inserted. Then, as shown in FIG. 2 (b), the connecting rod 2 is inserted into the tenon hole 14 of the column 13 with the notch 7 side as a tip, and then the connecting rod 2 is inserted into the connecting rod 2 as shown in FIG. The fixing pin 4 is inserted in the direction of the arrow in the drawing over the fixing pin insertion holes 5a, 5b, 5c, 5d formed and the pin holes 15 of the pillar 13 formed at positions corresponding to these holes. Pillar 13
Is fixed to the connecting rod 2.

On the other hand, as shown in FIG. 3A, a through hole 11 into which the connecting rod 2 can be inserted is formed in the base 10 in advance.
Further, on the lower surface of the base 10, the periphery of the through hole 11 is cut by the size and thickness of the seat plate 8 of the pedestal 3 to form a recess 12 in which the seat plate 8 can be embedded. As shown in (b), the seat plate 8 of the pedestal 3 is inserted into the depression 12 of the base 10 with the helical male screw 9 facing upward and buried, and the base 10 is placed on a foundation concrete 16. As shown in FIG. 3C, the pedestal 3 is fixed at a predetermined position by the base 10 and the foundation concrete 16.

Finally, as shown in FIG. 4, the column 13 to which the connecting rod 2 is fixed is rotated on the upper surface of the base 10 as indicated by an arrow, and the spiral female screw 6 of the connecting rod 2 is The screw 13 is screwed into the spiral male screw 9, whereby the column 13 and the base 10 are fastened and joined. At this time, the protruding portion of the connecting rod 2 which is inserted and fixed in the tenon hole 14 of the column 13 and whose lower end protrudes from the lower surface of the column 13 serves as a tenon, and is formed in the base 10. Since the through-hole 11 serves as a mortise, the pillar 13 can be reliably and smoothly installed at a predetermined position on the base 10.

In the present invention, the connecting rod 2, the pedestal 3, and the fixing pin 4 may be made of metal, but may be made of metal, but have relatively high rigidity and are resistant to external forces such as tension, compression, and torsion.
Iron, various steels, stainless steels, etc., which are rich in punching and cutting workability and are relatively inexpensive, are suitably used.

The shape of the connecting rod 2 is not limited to a cylindrical shape, but may be any shape such as a round bar or a square bar. However, when the connecting rod 2 is a solid rod and the screw formed at the lower end is a female screw, a hollow portion including the female screw is formed at least as long as the male screw of the pedestal, and It is preferable that the diameter of the portion excluding the female screw is larger than the maximum diameter of the male screw. With the above configuration, the connecting rod 2 can be screwed deeply until the lower end surface of the connecting rod 2 contacts the upper surface of the seat plate 8 of the pedestal 3. When the notch 7 is formed at one end of the connecting rod 2 as described above,
When the connecting rod 2 is inserted into the mortise hole 14 of the pillar 13 through the through hole 11 of the base 10, the notch 7 serves as a guide, so that the insertion operation can be performed smoothly, which is preferable.

The screw formed at the end of the connecting rod 2 is not limited to a helical female screw, but may be a helical male screw. In this case, as the screw provided on the pedestal 3, a spiral female screw that can be screwed to the above-mentioned male screw is adopted. As for the screws of the connecting rod 2 and the pedestal 3, the longer the length of the male screw, the longer or shorter the total length of the connecting metal fitting 1 for building by changing the screwing depth of both screws. Can be used in a wider range, so that it can be used for a base having various thicknesses or a column having pin holes at various positions, which is preferable. The length of the female screw may be any length that does not allow the screwed male screw to be easily pulled out, but a longer length is preferable because the male screw can be more firmly attached.

The shape of the fixing pin insertion hole 5 is not limited to a circular cross section, but may be any shape as long as the fixing pin 4 can be inserted. Further, the number of the fixing pin insertion holes 5 is not limited to the above, and may be any number.

The shape of the seat plate 8 constituting the pedestal 3 is not limited to a disk shape, but may be various shapes such as a square shape, a cross shape, a T shape, an L shape, and a Y shape. it can.

When at least one end of the fixing pin 4 is formed in a tapered shape, the tapered portion serves as a guide when the fixing pin 4 is inserted into the fixing pin insertion hole 5 so that it can be easily inserted.

In using the architectural connection fitting of the present invention, the connection fitting main body is installed, and the fixing pin 4 is inserted between the pin hole 15 of the column 13 and the fixing pin insertion hole 5. It is preferable in appearance to fill the hollow portion with a plug (not particularly shown) to smooth the surface of the column 13.

Next, the operation of the construction fitting of the present invention will be described. FIG. 5 is a longitudinal sectional view showing a state in which the pillar is joined to the base using the connecting metal fitting for construction of the present invention. As shown in FIG. 5, the connecting metal fitting 1 for the construction of the present invention has the connecting rod 2 inserted in the tenon hole 14 of the pillar 13 so as to be horizontal (arrow a in the drawing).
Direction) and the tilting direction (the direction of the arrow b in the figure), and the connecting rod 2 is fixed to the column 13 by the fixing pin 4 so that it does not pull out from the tenon hole 14 of the column 13. Further, since the upper surface of the pedestal 3 is in contact with the lower surface of the base 10, the connecting rod 2 and the pedestal 3 do not come off in the direction of the upper surface of the base 10.

When the column 13 is set on the base 10, the connecting rod 2 is inserted into the through hole 11 formed in the base 10, and the lower end of the connecting rod 2 and the pedestal 3 are connected to the base. 10 and the column 13 is thereby fastened to the base 10, so that the lower peripheral wall of the connecting rod 2 is supported by the inner wall of the through-hole 11 so that it is horizontal (arrow a in the figure). Direction) as well as in an inclined direction (arrow b direction in the figure), and the connecting rod 2 and the pedestal 3 do not fall out toward the upper surface of the base 10, so that the column 13 does not fall out of the base 10. Pillar 13 is base 10
And the weight on the pedestal 3 via the connecting rod 2 is reduced by the foundation concrete 16 under the base 10.
, So that it does not directly touch the base 10.

Further, since the column is fastened to the base and the joint between the column and the base has already been compressed at a high density, for example, if the base or the column is dried and parts other than the joint are shrunk. If so, no new shrinkage occurs at this joint, so there is no danger of creating a gap between the column and the base.

[0022]

[Effects of the Invention] Since the connecting metal fittings for construction of the present invention are configured as described above, the pillars can be firmly joined and fixed on the base, so that the pillars do not come off from the base due to a pitching earthquake or the like. It has an effect that can be prevented. In addition, since the pedestal is placed directly on the foundation concrete, the weight of the column is divided into a part applied to the base concrete via the connecting metal fitting and a part directly applied to the base at the joint surface between the base and the column. Therefore, there is an effect that it is possible to prevent the pillar from sinking into the base caused by directly supporting the pillar only at the joint surface with the pillar of the base.

In addition, since the connecting rod of the present invention has the same function as the tenon, the pillar can be accurately set at a predetermined position on the base. In addition, there is no need to perform a process for providing a tenon on the base or the pillar, which has the effect of reducing the time and effort for processing.

Further, the connecting metal fitting for construction of the present invention can be fixed by screwing the connecting rod and the pedestal, so that the total length of the connecting metal fitting can be freely changed depending on the depth of the screw. Therefore, if the architectural connection bracket of the present invention is used,
For example, after drilling a pin hole in a pillar, if the lower end of the pillar has been scraped off or if the position of the pin hole was originally too low, the reverse of the above, if the base was too thin, The reverse is the case where the design change requires a change in column length or base thickness.
There is an advantage that only one type of dimensional specification fitting is sufficient, and even if pillars or base materials that were temporarily processed with the wrong dimensions can be used as they are without rework, waste of material is reduced. There is an advantage that it can be eliminated and labor of processing can be saved.

Further, the connecting metal fitting for architectural construction of the present invention allows the connecting rod and the pedestal to be screwed together and fixed, so that the column can be fastened to the base, so that the connecting portion between the column and the base can be used. This has the advantage that no shrinkage of the base occurs and therefore there is no danger of a gap being created between the column and the base.

In addition, since the connecting rod and the pedestal of the architectural connecting bracket of the present invention are originally formed as separate bodies, the column is joined to the base after the base is installed on the foundation concrete. In the past, there is an advantage that the connecting rod does not protrude on the base and there is no extra protrusion on the base during the construction, so that the construction work is not hindered for safety.
