Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a metal fitting device for joining end parts of a fired material which is interposingly mounted on each corner of a column and a base, left and right bases or beams in construction. It is a thing.

[Conventional technology]

When connecting both ends of a conventional hitting material and another fitting member, each end surface of the hitting material and each inner surface of the fitting member joined to the end are fitted in a combination like a tenon and a mortise. After the unevenness is machined and then these machined parts are combined, a screw rod is skewed through an insertion hole penetrating the combined part and a nut is screwed and fastened to one of the protruding parts. ing.

[Problems to be solved by the device]

However, it is extremely laborious and time-consuming to make a combination for each attachment part of each piece of wood as mentioned above, and often a gap is created in the combination part, which results in a tight and strong bond. There was a pity that I couldn't do.

This plan is a cup-shaped main body that is suitable for a cylindrical cavity and a circular insertion hole that can be easily drilled by a drill or a hole-breaker for a fired material and an attachment member in order to eliminate conventional disadvantages. The fitting for metal fittings consisting of the tube and the tube is combined with a known washer, screw rod, and nut to form a fitting metal fitting device, and by using this device, anyone can always easily and tightly and firmly join the fitting fitting. It was done.

[Means for Solving the Problems]

That is, the metal fitting device for connecting the fired material in the construction of the present invention is constructed such that the inner wall of the cup-shaped main body fitted in the inner wall of the inner wall of the inner wall of the fired material is fitted with the cylindrical hole. A base end of a long pipe body inserted into an insertion hole formed from the center of the pipe to the outer end of the fired material is implanted, and the hollow portion of the pipe body penetrates to the outer surface of the cup-shaped main body. The insertion fitting that is configured and the insertion hole of the fitting other member that is formed on the same axis as the insertion hole of the fired material are skewed into the tubular body of the insertion fitting and one end is inserted. A threaded rod of the fitting for projecting to the outer end side of the fired material, a washer provided on the outer end slope of the fired material, and a projecting portion of the screw rod to the outer end side slope of the fired material is inserted, and the washer And a nut that is screwed and fastened to the projecting portion of the above-mentioned screw rod toward the sloped side of the outer end of the fired material. It is characterized in.

[Action effect]

As described above, in the present proposal, it is sufficient to form a cylindrical cavity and a circular insertion hole at the joining portion of the fired material and other members, respectively, so these can be easily and accurately formed with a drill or a hole-breaker. However, by using the metal fitting device which is constructed by adapting these to the cavity and the insertion hole, each fitting part is always tightly and firmly bonded together with the strength due to the pipe body and the screw rod. Since it does not require the skill and time required to form unevenness by cutting wood for each part, it has a great advantage that construction can always be done quickly and easily.

〔Example〕

As shown in the drawing, a columnar cavity R is provided on the slope of the inner end of the fired material 1 and an insertion hole H is formed in the same axial direction from the center of the cavity R to the outer end of the fired material 1. Then, the cup-shaped main body 2 of the insertion fitting 8 is fitted in the cavity R, the tube body 3 of the insertion fitting 8 is inserted in the insertion hole H, and the same axis line as the insertion hole H is inserted. A nut 7 is screwed and fastened through a deforming washer 6 to a projecting portion of a screw rod 5 with a screw head that passes through the pipe body 3 through an insertion hole H'of the beam member 4 that has been drilled. In addition to the joining, the striking material 1 was joined to the pillar 9 using the fitting material device for joining the striking material of the present invention in the same manner as described above.

[Brief description of drawings]

1 is a side view of an insertion fitting according to the present invention, FIG. 2 is a plan view of the same as above, and FIG. 3 is interposed at a corner of a joint between a column and a beam. FIG. 3 is a schematic side view with a main part missing showing a state in which both ends of a fired material are connected by a metal fitting device for a fired material of the present invention. 1 is a fired material, 2 is a cup-shaped main body, 3 is a tubular body, 4 is a beam, 5 is a screw rod, 6 is a deforming washer, 7 is a nut, 8 is a fitting for fitting, 9 is a pillar, and R is a cylindrical fossa Parts, H, H'are holes.
