Description

  The present invention relates to a joining device for a shaft assembly using a pipe-like tenon material in a wooden building.

  A square frame is provided in the middle part of the pipe-shaped tenon material, with one half inserted into the column and the other half inserted into the base, and the lower end of the column is engaged with the square frame, and the column and base (shaft There is a structure in which the assembly members are joined to each other (for example, Patent Document 1).

Japanese Patent Laid-Open No. 10-338968

  The conventional structure has a complicated structure because the main tenon, which is the main material that functions as a joint fitting, is embedded in the pillar and the base so that the main body is integrated with a rectangular frame. On-site construction becomes complicated.

  In order to avoid this complexity, it may be possible to pre-assemble the joint fitting on the column side in the factory. However, assembling the joint fitting increases the so-called bulk, which causes inconvenience in transportation. In any case, there is a limitation in use because it is in a state at the time of joining and a part (square frame) of the joining metal fitting is exposed to the outside.

  The present invention was devised for the purpose of providing a joining device for a shaft assembly using a pipe-like tenon material in a wooden building, in which the joining bracket can be accommodated in the shaft assembly without being exposed to the outside. Is.

The lower framing material is provided with engagement holes in the position corresponding to mortise provided in the upper framework member to be bonded to framing material of the lower side, the engagement Goana, the mortise The pipe-shaped joint material to be engaged is engaged, and the pipe-shaped joint material is provided with a guide long hole extending in the axial direction and a connection hole disposed above the pipe-shaped joint material. Protruding edges for forcibly getting over the support rods are provided on the opposite side edges of the guide elongated holes at the lower side edges of the guide assembly. Then, when the support rod is clamped, a through hole for inserting the connection rod, which coincides with the connection hole, is provided laterally on the upper shaft assembly.

  Further, the pipe-shaped joining material is formed of a cylindrical body in which a rectangular metal plate is bent into a substantially S shape and a partition wall is provided in the center along the longitudinal direction, so that no welding work is required for forming the cylindrical body. Therefore, it is possible to obtain a pipe-shaped joining material at a low cost since it can be manufactured by simple bending, and it is possible to provide a joining device for a shaft assembly material that is further superior in joining strength.

  According to the present invention, the support rod can be joined in the lower shaft assembly material and the upper shaft assembly material, and both shaft assembly materials can be joined without being exposed to the outside. Since it is sufficient to hold the state where a part of the pipe-shaped joining material protrudes and to engage the upper shaft assembly with the protruding part, the joining work can be performed without any inconvenience.

FIG. 3B is a sectional view taken along line b-b. The perspective view of a pipe-shaped joining material. The partial front view of the other Example of a pipe-shaped joining material. Sectional drawing of FIG.

  In the figure, 1 is a pipe-shaped bonding material, and the pipe-shaped bonding material 1 is formed of a cylindrical body in which a rectangular metal plate is bent in a substantially S shape and a partition is provided at the center along the longitudinal direction. And a guide hole 2 which is long in the axial direction and which opens a part of the peripheral wall 1 ″ and communicates with each other through the partition wall 1 ′, and a connection hole 3 which is located above the guide slot 2 Protruding edges 6 and 6 are provided on the opposite side edges 2 'and 2' at the lower part of the guide slot 2, which are provided only on the partition wall 1 ', but may be provided on the peripheral wall 1 ". A gap between the projecting edge 6 and the lower edge 2 '' of the guide slot 2 is formed as an engagement gap 2a of a support rod 5 which will be described later, and the support gap 5a is moved upward when the engagement gap 2a is moved upward. The flange 5 is forcibly passed through the narrow portion of the guide slot 2 where the projecting edge 6 exists and engages.

  Then, the pipe-shaped joining material 1 is engaged with the engagement hole 4 provided on the upper surface of the lower shaft assembly material p to be joined to the upper shaft assembly material b with the guide long hole 2 side facing down. The support rod 5 having a circular cross section is passed through the guide elongated hole 2 and the through hole 10 provided at an appropriate position of the lower shaft assembly material p so as to coincide with the guide elongated hole 2 and joined. The material 1 is assembled to the lower shaft assembly material p, and the upper shaft assembly material b is provided with a mortise 7 that coincides with the engagement hole 4 and a through hole 8 that is orthogonal to the mortise 7. At the site, the bonding material 1 is pulled out from the engagement hole 4 so that the upper side on the connection hole 3 side protrudes, and the engagement gap 2 a provided in the bonding material 1 is moved upward, and the protruding edge 6 of the bonding material 1. Forcibly passing the narrow portion of the guide elongated hole 2 where the support rod 5 is engaged, and the support rod 5 is relatively engaged in the engagement gap 2a. Hooking to the extended state from the engagement hole 4 is maintained.

  Then, the upper shaft assembly material b is engaged with the mortise 7 by engaging the upper side of the pipe-shaped bonding material 1 projected from the engagement hole 4 of the lower shaft assembly material p, and the lower shaft assembly material b. Put the connection rod (drift pin) 9 in the through hole 8 provided on the connecting hole 3 of the bonding material 1 and the upper shaft assembly b corresponding to this, and place the upper and lower shaft assemblies b, p Join.

  In the embodiment, in the fastening bolts c, c ′, and c ′ for fixing the joint metal m for joining the horizontal member a which is another shaft member to the lower shaft member p, to the shaft member p. However, it is needless to say that the present invention may be applied to a joining apparatus having a structure that does not use the joining metal fitting m. In the case of the embodiment, the depth of the engagement hole 4 is shallower (shorter) than the length of the pipe-shaped bonding material 1 due to the positional relationship of the tightening bolts c and c ′ for fixing the bonding metal m to the shaft assembly p. The joining material 1 is assembled to the shaft assembly material p so that a part of the joining material 1 always protrudes from the shaft assembly material p, but the joining metal m and the fastening bolts c and c ′ for fixing the joining metal m are omitted. In the case of a structure that is not used (for example, a structure in which only the upper and lower shaft assembly materials b and p are simply joined together), the depth of the engagement hole 4 can be freely selected. If the length of the joining material 1 is equal to or longer than 1, the joining material 1 can be stored in its entire length in the engagement hole 4, and the shaft assembly material p assembled with the joining material 1 only by the support rod 5 is conveyed. Since the support rod 5 does not protrude, it is possible to prevent the conveyance amount from being reduced due to the protrusion.

  The pipe-shaped bonding material 1 shown in FIGS. 7 and 8 has a protruding edge 6 that is inclined so that the amount of protrusion gradually increases from the upper side to the lower side of the bonding material 1. The relative movement along the inclined shape can be performed smoothly, and the remaining points are the same as in the first embodiment.
