[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is used for constructing a wooden building, which is provided to straddle a pillar on a lower floor and a pillar on an upper floor through a beam and to connect both pillars through the beam. It is a connecting tool.

[0002]

[Prior art]

 Conventionally, in the construction of wooden houses, etc., when constructing a building with two or more stories, specifically, for example, when constructing a two-story wooden building, it is necessary to provide hoso holes above and below the beam, A method is to install a hoso on each pillar and connect the pillars on the first and second floors with beams by fitting the hoso and the hoso hole. A single pillar with a length from the first floor to the second floor, a so-called through-column, is used, and a tenon hole is provided on the side of this column, and the tenon of the beam with the tenon at the tip is fitted into the tenon hole of the above-mentioned column. By fixing the beam to the side surface of the column, or by using the above-mentioned through column, the beam receiving metal fixture is fixed to the column and the beam is supported by the beam receiving metal fixture. Is used.

[0003]

[Problems to be solved by the device]

 However, according to the former method, the processing of the tenon is very time-consuming, and the strength of the connection between the first- and second-tier pillars through the beams is sufficient due to the fitting of the tenon and the tenon hole. Instead, there was a risk that the columns would pull out from the beams and the structure on the second floor would collapse due to the vertical pulling out of the beam due to vertical earthquakes. Further, according to the latter method, since the beam is fixed to the side surface of the column, a force is constantly applied to cause the displacement of the fixing point, which causes a drawback that the fixing point is easily loosened. In the case of providing the mortise and the mortise hole, there is a drawback in that it takes the same labor as described above.

[0004]

[Means for Solving the Problems]

 The present invention has been made in view of the above points, and it is not necessary to provide a hoso on a pillar or a beam, and the pillars on the lower floor and the upper floor, for example, the pillars on the first and second floors can be firmly fixed through the beams. An object is to provide a building connection fitting that can be connected. That is, the construction connecting metal fitting of the present invention has two connecting rods each having a fixing pin insertion hole formed at a predetermined position and an internal thread or a male screw formed at an end thereof, and an end portion of each connecting rod. It is characterized by comprising a connecting rod having at least both ends of a male screw or a female screw capable of being screwed into a screw, and a fixing pin inserted into the fixing pin insertion hole of each of the connecting rods.

【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, and FIG. 1 is a perspective view showing one example of the construction connecting fitting of the present invention. For example, as shown in the figure, the construction metal fitting 1 for construction of the present invention comprises a connection rod 2 (21, 22), a connecting rod 3 and a fixing pin 4. Each of the connecting rods 21 and 22 is a cylindrical body having the same diameter and length, and a fixed pin having a circular cross section is inserted at a position inside a predetermined length from one end thereof in a direction perpendicular to the axis and in a direction perpendicular to each other. Holes 5a and 5b are formed so as to be adjacent to each other and penetrate the connecting rod 2, and above the fixing pin insertion holes 5a and 5b are fixed pin insertion holes similar to the fixing pin insertion holes 5a and 5b. 5c and 5d are bored, and a spiral female screw 6 is formed at the lower end of the connecting rod 2 along the axis of the connecting rod 2, and a female part of the hollow portion of the connecting rod 2 is formed. The diameter of the portion excluding the screw is larger than the maximum diameter of the male screw forming the connecting rod 3 described later. Further, a notch 7 having a tapered notch is formed at the upper end of the connecting rod 2. The connecting rod 3 is a full-threaded bolt having a spiral male screw formed over the entire length thereof and capable of being screwed into the spiral female screw 6. Further, the fixing pin 4 is a round bar body having a diameter slightly smaller than the diameter of the fixing pin insertion hole 5 of the connecting rod 2 and having both ends tapered.

FIG. 2 and FIG. 3 are views for explaining means for connecting columns of the first floor and the second floor via a beam by using the building metal fitting of the present invention, and FIG. FIG. 3 is a perspective view showing a state in which two columns are connected to each other through a beam by using the construction connecting fitting of the present invention. In order to connect the pillars of the first floor and the second floor through the beams using the connecting fitting 1 for construction of the present invention, for example, as shown in FIG. 2 (a), the connecting rods are previously connected to the pillars 8 (81, 82). 2 (21, 22) can be inserted into a hollow hole 9 and a pin hole 10 into which a fixing pin 4 can be inserted. Then, as shown in FIG. 2 (b), the connecting rod 2 is connected to the hollow hole 9 of the pillar 8. After inserting the side with the cutout portion 7 as the front end, the fixing pin insertion holes 5a, 5b, 5c, 5d formed in the connecting rod 2 and the pin of the pillar 8 formed in a position corresponding thereto. The fixing pins 4 are inserted in the directions of the arrows in the drawing over the holes 10 to fix the connecting rods 2 to the columns 8. In this fixed state, the end portion of the connecting rod 2 projects outward from the end surface of the column 8.

On the other hand, a through hole 12 into which the connecting rod 2 can be inserted is previously formed in the beam 11 at a connecting position with the pillar 8.

Then, as shown in FIG. 3, a pillar 81 of the first floor to which the connecting rod 21 is fixed is fixed on the base (side not shown) with the side of the connecting rod 21 facing upward, and then fixed. The beam 11 is placed on the pillar 81 so that the more protruding connecting rod 21 is inserted into the through hole 12 formed in the beam 11. After that, the connecting rod 3 is screwed into the connecting rod 21 through the through hole 12 of the beam 11, and finally the second-level pillar 82, to which the connecting rod 22 is fixed in the same manner as the pillar 81, is attached to the upper surface of the beam 11 by the arrow in the figure. As shown, the connecting rod 21 of the column 82 is screwed into the connecting rod 3, thereby connecting the column 81 and the column 82 through the beam 11. At this time, the projecting portion of the connecting rod 2 which is inserted into and fixed to the mortise hole 9 of the pillar 8 and whose end portion is projected from the lower surface of the pillar 8 functions as a mortar and is also bored in the beam 11. Since the through hole 12 functions as a hollow hole, the beam 11 can be surely and smoothly installed at a predetermined position of the pillar 81 and the pillar 82 at a predetermined position of the beam 11.

In the present invention, the connecting rod 2, the connecting rod 3 and the fixing pin 4 may be made of metal, but they have relatively high rigidity and are strong against external forces such as pulling, compressing and twisting and punching. Iron, various steels, stainless steel, etc., which are relatively inexpensive and have excellent machinability, are preferably used.

The shape of the connecting rod 2 is not limited to a cylindrical shape, and may be any shape such as a round bar shape or a square bar shape. However, when the connecting rod 2 is a solid rod and the screws formed at both ends are female screws, the length of the hollow portion including the female screw is long and the female screw is excluded from the hollow portions. The diameter of the portion is preferably larger than the maximum diameter of the male screw. Further, as described above, when the cutout portion 7 is formed at one end of the connecting rod 2, the cutout portion 7 is formed when the connecting rod 2 is inserted through the through hole 12 of the beam 11 into the mortise hole 9 of the column 8. It is preferable because it plays the role of a guide and the insertion work can be done smoothly.

The screw formed at the end of the connecting rod 2 is not limited to the spiral female screw, but may be a spiral male screw. In this case, as the screw provided on the connecting rod 3, a spiral female screw that can be screwed into the spiral male screw is adopted. As for the screws of the connecting rod 2 and the connecting rod 3, the longer the length of the male screw is, the longer or shorter the total length of the building connecting metal fitting 1 can be changed by changing the screwing depth of both screws. Since it can be performed in a wider range, it can be used for beams having various thicknesses and columns having pin holes at various positions, which is preferable. The length of the female screw may be such that the screwed male screw cannot be easily pulled out, but a long length is preferable because the male screw can be gripped more firmly.

The shape of the fixing pin insertion hole 5 is not limited to a circular cross section, and 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 connecting rod 3 is not limited to the above-mentioned full threaded bolt, and may be formed with screws at least at both ends. Specifically, for example, both ends may be female screws, both ends may be male screws, or one end may be a female screw and the other end may be a male screw.

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

Next, the operation of the architectural connecting fitting of the present invention will be described with reference to FIG. As shown in the figure, the connecting rod 1 for construction of the present invention has the connecting rod 2 inserted into the hollow 9 of the column 8 so that it can be inclined in the horizontal direction (the direction of arrow a in the figure). It does not move in the direction of the middle arrow b), and since the connecting rod 2 is fixed to the pillar 8 by the fixing pin 4, it cannot be pulled out from the hollow hole 9 of the pillar 8.

When the columns 81 and 82 are connected via the beam 11 with the beam 11 interposed therebetween, the portions of the connecting rods 21 and 22 projecting from the end faces of the columns 81 and 82 are connected to the beam 11. The lower end of the connecting rod 21 and the upper part of the connecting rod 3 and the upper end of the connecting rod 22 and the lower end of the connecting rod 3 are screwed into the through hole 12 formed in 1, 82 are connected so as to clamp the beam 11 from both the upper and lower sides, so that the peripheral wall of the portion of the connecting rods 21, 22 protruding from the column is supported by the inner wall of the through hole 12 of the beam 11. Therefore, the column 81 and the column 82 do not move not only in the horizontal direction (direction of arrow a in the figure) but also in the direction of inclination (direction of arrow b in the figure), and the columns 81 and 82 are not disengaged only by pulling in both directions. Furthermore, the columns 81 and the beams 11 and the beams 11 and the columns 82 are Each is tightly coupled.

Further, since the beam 11 is fastened from both the upper and lower directions by the two columns 81 and 82, and the joint between the two columns and the beam is already compressed at a high density, for example, the beams and the columns are dried. Even if the parts other than the joint part may contract, no new contraction occurs in this joint part, and therefore, there is no fear that a gap is generated between the column and the beam.

The building metal fitting of the present invention is mainly used to connect a pillar on the lower floor and a pillar on the upper floor with a beam between them when mainly constructing a two-story building using a wooden structural material. It is used, but not limited to this, and may be applied as described above to, for example, a wooden three-story building or more.

[0019]

[Effect of device]

 Since the connecting fitting for building of the present invention is constructed as described above, the pillar on the lower floor and the pillar on the upper floor can be firmly connected to each other through the beam, and therefore the lower pillar due to a vertical shaking earthquake or the like can be connected. It is possible to prevent the beams from coming out of the columns on the floor, or the columns on the upper floor from coming off from the beams, or the columns on the lower floor, the columns on the upper floor, and the beams all coming off. Have. Also, since the lower side of the present invention connecting bracket is fixed to the pillar on the lower floor and not directly to the beam, the weight of the pillar on the upper floor is applied to the pillar on the lower floor via the connecting bracket. And the amount directly applied to the beam at the joint surface between the beam and the column. Therefore, there is an effect that it is possible to prevent the column from being embedded in the beam, which is caused by directly supporting the column only at the joint surface of the beam.

In addition, since the connecting rod of the present invention has the same function as the hoso, the beam can be installed accurately at the predetermined position of the pillar on the lower floor, and the pillar on the upper floor can be installed accurately. It can be installed accurately at a fixed position on the top surface. In addition, there is no need to process the beam or the column to form the mortise, which has the effect of reducing the time and labor required for the process.

In addition, in the construction connecting fitting of the present invention, since the connecting rod and the connecting rod can be screwed and fixed, the total length of the connecting fitting can be freely changed depending on the depth of screwing. . Therefore, if the building connection fitting of the present invention is used, for example, when a pin hole is drilled in a pillar and then the lower end of the pillar is scraped off, or the position of the pin hole is originally too low, or the opposite case to the above. , If the thickness of the beam is too thin, or in the opposite case, the length of the column or the thickness of the beam must be changed due to design changes. However, there is an advantage in that it is sufficient to use a connecting metal fitting with one type of dimension specification. Moreover, since a pillar or beam material that has been erroneously dimensioned can be used as it is without re-machining, it is a waste of material. There is an advantage that it can be eliminated and the labor of processing can be saved.

In addition, since the construction connecting fitting of the present invention is configured such that the connecting rod and the connecting rod can be screwed and fixed together, the beam can be fastened in the vertical direction by the two columns. There is an advantage in that there is no contraction between columns and beams at the joints between columns and beams, so that there is no risk of creating a gap between columns and beams.
