[Industrial applications]

 TECHNICAL FIELD The present invention relates to a building connecting tool for straddling a base and a pillar to join the base and the pillar.

[0002]

[Prior art]

 In the past, when building a house, etc., a pillar was installed on the base, and the pillar was connected and fixed to the base by forming a hoso on the side of the pillar at the joint between the base and the pillar. However, a mortise hole that fits with the mortise was formed on the side of the base, and the column mortise was fitted into the mortise hole of the base.

[0003]

[Problems to be solved by the device]

 However, according to the conventional fixing method, the base and the column are only joined and fixed by the fitting of the column mortise and the base mortise hole, and the joint strength cannot be said to be sufficient. There was a risk that the pillar could pull out from the base in response to the vertical shaking caused by the earthquake. Moreover, the processing of hozo was very time-consuming. The present invention has been made in view of the above points, and an object of the present invention is to provide a construction connecting metal fitting that does not require a tenon to be provided on a column and has a high joint strength at a joint.

[0004]

[Means for Solving the Problems]

 The construction connecting fitting of the present invention comprises a connecting fitting main body comprising a connecting rod having a fixing pin insertion hole penetrating the connecting rod and a seat plate provided at one end of the connecting rod, and the fixing of the connecting fitting main body. It is characterized by comprising a fixed pin inserted into the pin insertion hole.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The drawing shows one embodiment of the present invention, FIG. 1 is a perspective view showing an example of the construction connecting fitting of the present invention, and FIG. 2 is a state in which a pillar is connected to a base using the construction connecting fitting 1 of the present invention. FIG. 6 is a vertical cross-sectional view taken along the axis of the connecting rod.

As shown in FIG. 1, a building metal fitting 1 of the present invention comprises a metal fitting body 2 and a fixing pin 3. In the connecting fitting body 2, a disc-shaped seat plate 6 is fixed to the lower end of a cylindrical connecting rod 5 by welding or the like, and the connecting rod 5 has a thickness of at least the base from the lower end face of the seat plate 6. Fixed pin insertion holes 4c and 4d, which are circular in cross section and perpendicular to each other in the direction perpendicular to the axis, are formed adjacent to each other through the connecting rod 5 and are further fixed to the above positions. Fixed pin insertion holes 4a and 4b similar to the fixed pin insertion holes 4c and 4d are formed above the pin insertion holes 4c and 4d. A notch 7 having a tapered notch is formed at the upper end of the connecting rod 5.

The fixing pin 3 is a round bar body having a diameter slightly smaller than the diameter of the fixing pin insertion hole 4 of the connecting fitting body 2 and having both end peripheral portions tapered.

FIG. 2 is a perspective view for explaining a means for joining a pillar to a base using the construction connecting fitting of the present invention. As shown in FIG. 2, in order to join the pillar to the base using the construction metal fitting 1 for construction of the present invention, as shown in FIG. The periphery of the through hole 9 is cut by the size and thickness of the seat plate 6 of the coupling fitting body 2 to form a recess 14 in which the seat plate 6 can be embedded. Further, the post 11 is provided with a dowel hole 12 into which the connecting rod 5 can be inserted and a pin hole 13 into which the fixing pin 3 can be inserted (FIG. 9 (a)).

Then, the connecting rod 5 is inserted into the through hole 9 of the base 8 from the side of the recess 14 until the seat plate 6 is embedded inside the recess 14, and the upper part of the connecting rod 5 is the base 8. The foundation 8 is installed on the foundation concrete 10 in a state of protruding upward from the upper surface, and the connecting rod 5 protruding upward from the upper surface of the foundation 8 is inserted into the mortise hole 12 of the pillar 11. The pillar 11 is placed on the base 8 and the pillar 11 is fitted into the connecting rod 5, and the fixing pin insertion holes 4a, 4b, 4c, 4d formed in the connecting rod 5 and the positions corresponding to these are provided. The fixing pins 3 are inserted in the direction of the arrow a in the figure over the pin holes 13 of the punched columns 11, respectively, so that the columns 11 do not move in the axial direction of the coupling rod 5 by the fixing pins 3. 2 and the pillar 11 is joined to the base 8 via the building connection fitting 1 (see FIG. b)).

In the present invention, the connecting rod 5 constituting the connecting fitting body 2 has relatively high rigidity, is strong against external force such as tension, compression, and twisting, is excellent in punching and cutting workability, and is relatively inexpensive. Iron, various steels, stainless steels and the like are preferably used.

Further, the shape of the connecting rod 5 is not limited to a cylindrical shape, but may be any shape such as a round bar shape or a square bar shape. Further, as described above, if the notch 7 is formed at one end of the connecting rod 5, the notch 7 serves as a guide when the connecting rod 5 is inserted through the through hole 9 of the base 8 into the mortise hole 12 of the pillar 11. It is preferable because it plays a role and the insertion work can be done smoothly.

The shape of the fixing pin insertion hole 4 is not limited to a circular cross section, and may be any shape as long as the fixing pin 3 can be inserted. Further, the number of the fixing pin insertion holes 4 is not limited to the above and may be any number.

As the material of the seat plate 6, the same material as that of the connecting rod 5 can be used. The shape of the seat plate 6 is not limited to the disc shape, and may be various shapes such as a square shape, a cross shape, a T shape, an L shape, and a Y shape. Further, the seat plate 6 may be integrated with the connecting rod 5.

As the material of the fixing pin 3, the same material as that of the connecting rod 5 can be used. Further, as described above, when at least one end of the fixing pin 3 is formed in a tapered shape, when the fixing pin 3 is inserted into the fixing pin insertion hole 4, the tapered portion serves as a guide and can be easily inserted.

In using the building connecting fitting of the present invention, as shown in FIG. 3, the connecting fitting body is installed, and the fixing pin 3 is inserted between the pin hole 13 of the pillar 11 and the fixing pin insertion hole 4. After that, it is preferable in appearance to fill the hollow portion of the pin hole 13 (not particularly shown) with a plug to smooth the surface of the column 11.

Next, the operation of the construction connecting fitting of the present invention will be described. FIG. 3 is a vertical cross-sectional view showing a state in which a pillar is joined to a base by using the construction connecting fitting of the present invention. As shown in FIG. 3, the present invention connecting fitting 1 has a connecting rod 5 inserted into a through hole 9 formed in a base 8, and a lower peripheral wall of the connecting rod 5 is an inner wall of the through hole 9. Since it is supported by, it does not move not only in the horizontal direction (direction such as arrow a in the figure) but also in the inclined direction (direction such as arrow b in the figure), and the upper surface of the seat plate 6 at the lower end is the lower surface of the base 8. Since the connecting metal fitting body 2 is firmly attached to the base 8 without coming off in the upper surface direction of the base 8 because it is abutted against the base 8, the weight of the connecting metal 1 is applied to the foundation concrete 10 under the base 8. As a result, the base 8 is not directly applied.

The upper part of the connecting rod 5 projects above the base 8, and the projecting portion plays the role of a mortise, and the projecting portion of the connecting rod 5 is inserted into the mortise hole 12 formed in the pillar 11. Since it is inserted, the pillar 11 is securely installed at a predetermined position on the base 8. Further, in the state where the pillar 11 is installed on the base 8, the upper part of the connecting rod 5 is inserted into the hollow hole 12 of the pillar 11, so that the pillar 11 can be horizontally moved like the connecting rod 5. It does not move in the tilting direction.

Then, the fixing pin 3 is inserted across the fixing pin insertion hole 4 formed in the portion of the connecting rod 5 protruding above the base 8 and the pin hole 13 provided in the pillar 11. Then, the pillar 11 is engaged with the connecting fitting body 2 so that the pillar 11 does not come off in the axial direction of the connecting rod 5. As a result of the above, the base 8 and the pillar 11 are firmly joined so that the pillar 11 does not come off from the base 8.

[0019]

[Effect of the Invention] As described above, since the connecting fitting main body of the present invention has a structure in which the connecting fitting main body is provided with the seat plate at one end of the connecting rod, the connecting fitting main body is pulled out toward the upper surface of the base. The column can be firmly fixed to the base without any trouble, and the column can be engaged with the main body of the connecting metal fitting so that the column does not come off in the axial direction of the connecting metal fitting by the fixing pin. The base and the columns can be firmly joined to each other so that they will not come out of the base, and therefore the columns can be prevented from coming off the base due to a vertical shaking earthquake or the like. Further, since the seat plate is directly placed on the foundation concrete, the weight of the pillar is distributed between the portion applied to the foundation concrete through the connecting metal fittings and the portion directly applied to the foundation at the joint surface between the foundation and the pillar. Therefore, there is an effect that it is possible to prevent the pillar from being embedded in the base caused by directly supporting the pillar only at the joint surface of the base with the joint surface.

In addition, since the connecting rod of the main body of the connecting metal fitting of the present invention plays the same role as the hook, the pillar can be accurately installed at a predetermined position on the base. Moreover, there is no need to process the bases or pillars to provide the mortises, which has the effect of reducing the time and effort required for processing.
