Japanese Patent Laid-Open No. 2002-146918 [0004]
[Problems to be solved by the invention]
The conventional example has a special shape for the head of the bolt rod that constitutes the receiving projection so that the latching rod does not come off from the receiving projection (so that the horizontal member does not separate from the column). Bolts must be specially facilitated.
[0005]
In addition, the bolt 杆 is tightened to the column by screwing the nut, but the nut is forgotten to be tightened or the nut is loosened over time, and the desired hooking state for the column of the horizontal member is maintained. It may be difficult.
[0006]
In consideration of such a situation, the present invention has been devised to provide an apparatus that can reliably maintain the joining state of the horizontal member to the structural member.
[0007]
[Means for Solving the Problems]
A bearing composed of a screw member that penetrates the structural material and a nut material that is screwed and tightened to the joint surface of the structural material, such as a column or trunk, with a horizontal member, such as a beam or girder. On the other hand, the horizontal member is provided with an engaging groove for engaging the receiving protrusion from the lower end side, and an engaging groove for engaging with the receiving protrusion. The basic means is to cross the engagement groove, and for this basic means, for example, a flange piece is provided on the circumferential side of the nut material, facing the joint surface via a latching hook. By adding, a stable joining state of the horizontal member to the structural member can be obtained.

DETAILED DESCRIPTION OF THE INVENTION
The drawings show an embodiment of a joining apparatus for joining horizontal members in a wooden building according to the present invention, FIG. 1 is a longitudinal sectional view, FIG. 2 is a transverse sectional view, and FIG. 3 is a partially enlarged view of FIG.
[0009]
In the figure, 3 is a pillar (or a trunk difference), and the bolt 3 is passed through one of the side surfaces of the pillar 3 in each of the insertion holes 18, 18, 18 arranged in the longitudinal direction in the pillar 3, A receiving protrusion 4 or a second protrusion formed by screwing a nut material 4A into the tip 13a of the bolt rod 13 protruding from the other side surface which is a joint surface 3a to the horizontal member (beam or girder) 1. A receiving protrusion 4 'is provided.
[0010]
The nut member 4A, which constitutes the receiving protrusion 4 or the second receiving protrusion 4 'with the bolt rod tip 13a, is a cap nut composed of a screw cylinder 14 and a head portion that is connected to one end of the screw cylinder 14. The head is configured by interposing a flange piece 17 between the hexagonal head portion 15 and the truncated cone-shaped portion 16 adjacent to the screw cylinder 14 portion, and the flange portion 17 portion is a column. 3 having an outer diameter protruding from the peripheral side of the truncated cone-shaped portion 16 and the screw cylinder 14 so as to face the joint surface 3a, and the truncated cone-shaped portion disposed between the flange piece 17 and the screw cylinder 14 16 is arranged coaxially with the screw cylinder 14 and gradually increases in diameter from the screw cylinder 14 toward the flange piece 17 and is provided with a tapered edge 16a on the circumferential side.
[0011]
A receiving protrusion 4 projecting in a longitudinal direction on the joint surface 3 a of the column 3 and second receiving protrusions 4 ′ and 4 ′ immediately below the receiving protrusion 4 are formed on the end surface of the horizontal member 1. A latching rod 5 or a second latching rod 5 ′ which is accommodated in the vertical engaging groove 7 and is laterally provided on the horizontal member 1 so as to cross the engaging groove 7 and correspond to each protrusion 4. In addition, a latch rod 6 is provided on the horizontal member 1 in the same manner as the second latch rod 5 'below the lowermost support protrusion 4'. The horizontal member 1 is joined to the column 3 so that the lowest support protrusion 4 is sandwiched between the hooks 5 '.
[0012]
In addition, since the receiving protrusion 4 or 4 'receives the load of the horizontal member 1 via the hooking rod 5 or the second hooking rod 5', if the protruding amount from the column 3 is large, the load resistance is increased. Therefore, it should be reduced as much as possible, but reducing the protruding amount of the receiving protrusions 4 and 4 ′ means that the hanging rod 5 installed horizontally on the horizontal member 1 side This means that the horizontal position of the second hook 5 'approaches the end face side of the horizontal member 1. And since the load of the horizontal member 1 will be loaded by the latching rods 5 and 5 'being latched on the receiving protrusions 4 and 4', the horizontal installation of the latching rods 5 and 5 ' The closer the position is to the end face of the horizontal member 1 (joint surface with the column 3), the more easily the horizontal member 1 is torn due to the concentration of its own weight on the hooks 5 and 5 '.
[0013]
In the embodiment, in order to prevent this tear due to the load resistance of the receiving protrusion 4 and the weight of the horizontal member loaded on the latching rods 5 and 5 ′, the engagement groove 7 provided in the horizontal member 1 A pair of reinforcing plates 2 and 2 made of a steel plate (metal plate) is provided. That is, the engagement groove 7 is composed of a rectangular large portion 7a and small diameter portions 7b and 7b which are communicated in the form of slits at both corners of the back wall of the large diameter portion 7a. The reinforcing plate 2 is superposed on the inner side of the side wall of the engaging groove 7 (large diameter portion 7a) so that the base end side is inserted into the small diameter portion 7b of the base plate 7, and is arranged in the vertical direction on the base end side of the reinforcing plate 2 A fixing rod (drift pin) 9 is driven into the through hole through a first fitting insertion hole 8 provided in the horizontal member 1 so as to cross the engaging groove small diameter portion 7b and to coincide with the through hole. Then, a pair of reinforcing plates 2 and 2 are inserted and installed in the engaging groove 7 with a gap 10 therebetween.
[0014]
And the reinforcement board 2 assembled | attached to the horizontal member 1 has the 2nd through-holes 11 and 11 provided in the front end side arranged in the vertical direction similarly to the said through-hole provided in the vertical direction in the base (rear) end side. ′, 11 ′, 11 ′, which are positioned in the large-diameter portion 7 a of the engaging groove 7, in the horizontal direction 1 like the first fitting insertion holes 8, 8, 8 in the vertical direction These are aligned with the second insertion holes 12, 12 ', 12', 12 'provided side by side.
[0015]
The horizontal member joining apparatus according to the embodiment includes a reinforcing plate 2 on the horizontal member (beam or girder) 1 side, and a receiving protrusion 4 and a second receiving protrusion 4 on the pillar (or body difference) 3 side. 'Is provided as described above, and the latching rod 5, the second latching rod 5' and the latching rod 6 which are installed horizontally on the side of the horizontal member 1 through the reinforcing plate 3 are assembled to the receiving protrusion 4. Thus, the horizontal member 1 is joined to the column 3.
[0016]
In order to obtain the joining state of the horizontal member 1 to the column 3, as described above, the receiving projection 4 and the second receiving projection 4 ′ are arranged directly below the receiving projection 4 on the column 3 side. On the other hand, on the horizontal member 1 side, as described above, the uppermost second through hole 11 of the reinforcing plate 3 assembled by the fixing rod 9 and the horizontal member 1 that coincides with the second through hole 11 are provided. A horizontal member 1 in which a latching rod 5 is installed so as to intersect with the engaging groove 7 so as to be fitted into the uppermost second insertion hole 12 provided, and the latching rod 5 is assembled. When the end portion is positioned directly above the receiving protrusion 4 and lowered, the horizontal member is engaged while the receiving protrusion 4 is relatively engaged in the engagement groove 7, that is, the gap 10 between the reinforcing plates 2 and 2. One end part descends, and with this descending, the latching bar 5 laid horizontally on the upper side of the end part of the horizontal member 1 also descends, and finally the uppermost support protrusion projecting on the column 3 side. 4 and the horizontal member 1 is a support for the hook 5 It is temporarily joined to the pillar 3 by the engaging relationship to child 4.
[0017]
At the time of this temporary joining (when the latching rod 5 is placed on the receiving projection 4), the latching rod 5 is formed by the inclination of the tapered edge 16a of the receiving projection 4 (conical trapezoidal portion 16). Accordingly, the horizontal member 1 is also moved and pulled toward the column 3 side, and a stable (temporary) joined state can be obtained (the relative positional relationship of each member is Of course, it is set so that the drawing operation is performed).
[0018]
In this temporarily joined state (in some embodiments, after obtaining this temporarily joined state, it is possible to fix the column 3 and the horizontal member 1 by shaving or the like), and the reinforcing plate on the horizontal member 1 side The second through-hole 11 'provided in 2 and the second fitting insertion hole 12' provided at the end of the horizontal member 1 so as to intersect with the engaging groove 7 are arranged at positions coincident with each other. The second hooking rod 5 'can be driven into and inserted into these, and the second hooking hole 12' (in FIG. ) And the second latching rod 5 ′ in the second lowest through hole 11 ′ (shown as 11 ′ b in the figure) that coincides with the second insertion hole 12 ′. The horizontal member 1 is joined to the column 3 by fitting and driving in the same manner as when fitting and driving into the fitting hole 12 ′ and the second through hole 11 ′.
[0019]
During the driving operation of the second hooking rod 5 ′ and the locking rod 6, each of the rods 5 ′, 6 forcibly contacts and presses the tapered edge 16 a of the receiving protrusion 4, A drawing operation in the direction of the pillar 3 is performed.
[0020]
In the joined state, the latching rods 5 and 5 ′ are latched by the receiving projections 4 and 4 ′ on the column 3 side, and the receiving projections 4 and 4 ′ are passed through the latching rods 5 and 5 ′. The load on the horizontal member 1 side is received.
[0021]
The locking rod 6 is in contact with the lower edge (tapered edge 16a) of the lowest support protrusion 4 ′ to prevent the horizontal rod 1 from rising along the column 3, and the latch rod 5 or other second By sandwiching the receiving protrusion 4 or 4 'with the hanging hook 5' (for example, in the case of the uppermost receiving protrusion 4, the hanging hook 5 is positioned in contact with the upper edge side thereof. The uppermost receiving protrusion 4 is sandwiched between the latching bar 5 and the locking bar 6 in contact with the lower edge of the lowermost receiving bar 4 '), and the column of the horizontal member 1 Preventing the departure from 3.
[0022]
In the figure, reference numeral 20 denotes a washer, and the washer 20 prevents the bolt head and the nut material 4A from collapsing into the pillar 3.
[0023]
In the embodiment, as shown in the drawings, the horizontal member 1 is joined only to one side (joint surface 3a) of the structural material (column 3). Therefore, the bolt member 13 is used on the one side. However, instead of the bolt rod 13 (with head), a screw rod provided with screw portions at both ends is used instead of the bolt rod 13 and the end portion is passed through the insertion hole 18. Projecting from both sides of the structural material, the nut material 4A is screwed and tightened to each end to form the receiving projection 14, and each receiving projection 14 on both sides of the structural material is laterally arranged as in the embodiment. Needless to say, the frame member may be joined, and the head of the bolt rod 13 according to the embodiment is merely the receiving protrusion 14 formed of the screw end portion and the nut member 4A, and the remaining points are implemented. Since it is the same as the form, description is abbreviate | omitted.
[0024]
【The invention's effect】
Since the present invention is configured as described above, it is possible to provide a device that can securely join the horizontal member to the structural material. Further, the bolt material is passed through the structural material, and the nut material is screwed to the tip of the bolt material. By simply doing this, it is possible to easily obtain a receiving projection for latching the latch on the side of the horizontal member, thereby shortening the construction period.
[0025]
In addition, since the hooking rod is hooked to the nut material that constitutes the receiving protrusion and the load of the horizontal member is applied, the nut material with respect to the bolt rod is prevented from loosening over time, and the receiving protrusion is prevented. It is possible to provide a device that can reliably maintain the initial latching state of the latching rod with respect to the child.
