Description

[Detailed description of the invention] The present invention relates to a device for joining building materials for wooden buildings (7), and in particular, connects horizontal frames such as beams, girders, sills, and foundations that are perpendicular to each other to a single through column. related to a device for

Traditional wooden frame buildings had a variety of construction methods for joints and joints, and these were processed at the construction site.
The drawbacks were that the construction period was long and the construction cost was high.

This invention standardizes all building materials and their joining structures, centrally processes all joints, joints, etc. in the factory, and at the construction site, these processed parts are used as joining fittings, dowels, etc. This invention was made in connection with the invention of a new wooden frame construction method that allows for the easy assembly of high-quality buildings simply by joining the wooden frames together.

The purpose of this invention is to be suitable for mass production in a factory, with almost no processing required at the construction site, and therefore with little variation in quality and strong joints.
The purpose of the present invention is to provide a framework structure for a wooden building that has excellent resistance to lateral loads and torsional loads caused by earthquakes, etc.

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 1 is an exploded perspective view showing an embodiment in which the present invention is applied to the joining of girders, and FIG. 2 is a diagram showing the joined state.

A second
The end faces of the girders 2, 2 forming the members are joined to form a cross-shaped girder joint.

Both the girders 1 and 2 have shallow central grooves 13, 13 and 21, 21 along the longitudinal direction on both upper and lower side surfaces.

This is used when constructing intermediaries such as lintels and shims, and is also effective in distinguishing between upper and lower surfaces.

The dimensions of this groove are such that the cross-sectional area of the member is lQQ mm
In the case of IQQ mm, for example, width 30mm x depth 10m
It is m.

The end surface of the second member 2 has a portion 2 corresponding to the central groove 21.
4. For example, if the width of the central concave groove 21 is 39 mm, leave a 30 mm wide part in the center, and make a width of 2, for example, on both the left and right sides.
Concave grooves 23A and 23B with a diameter of 0 mm and a depth of 15 mm are carved in the vertical direction.

As a result, the end face has, for example, a central protrusion 2 with a width of 3Qmm.
4 and a left end protrusion 25A and a right end protrusion 25B each having a width of 15 mm are formed.

Further, a dowel hole 26 is bored approximately at the center of the central protrusion 24 to a predetermined depth.

Recesses 14 and 15A are formed at predetermined positions on the side surface 11.12 of the first member 1 in correspondence with such unevenness and dowel holes on the end surface.
, 15 B are carved so as to fit with the end surface of the second member, and the dowel is inserted through the dowel hole at the construction site to fit into the dowel hole 26 on the end surface of the second member.
so that it fits.

At the height of the end of the second member 2 where the dowel holes 26 are removed, --striped horizontal cut grooves 27 are carved, and the cut grooves 27 intersect with the cut grooves 27 on both left and right sides outside the central groove groove 21. Pin holes 28A, 28B are drilled at predetermined positions, and both left and right sides 29A,
A second bolt through hole 30 is drilled horizontally through 29B.

On the other hand, first bolt through holes 16A and 16B are also drilled in the horizontal direction near the joint surface of the first member 1 at the same height as the cut groove 27, passing through both the left and right side surfaces 11.12. .

The joining fittings 3 are made of backing plates 31 and 32 bent at right angles.
and has a penetration plate 33 that is integrally provided on one side 31 of the backing plate and perpendicular to the backing plate along the offshore center, and one side 31 of the backing plate.
Bolt holes 34, 34 are vertically symmetrically drilled in the plate, a bolt hole 35 is bored approximately in the center of the other side 32 of the backing plate, and a bottle hole 36 is bored in the penetration plate 33.

Either one of the bolt holes 34, 34 matches the bolt holes 16A, 16B of the second member in the joined state, and the bottle hole 36 is manufactured in advance in a factory so that it matches the pins JL28A, 28B of the second member. ing.

Note that if the center position of the pin hole 28A or 28B of the second member is eccentrically located farther from the end face than the center position of the pin hole 36 of the penetration plate 33, within the limits of the pin radius, the driving of the pin 6 will be easier. As a result, the second member is strongly pressed against the first member 1, and the joint structure is tightened.

The penetration part 33 of such a joining fitting 3 is made to penetrate into the cut groove 27 of the second member 2 joined to the first member 1 joined by the dowel and the dowel hole as described above, and both members 1 , 2 are attached to each of the four adjacent corners. First, lightly tighten the opposing second bolt holes 34 and 34 of the joining fittings and the bolt holes 30 of the second member with bolts 4, and then lightly tighten the bolts 4. The bolt holes 16A and 16B of the first member of the opposing first bolt holes 35 and 35 of the metal fittings are tightened strongly with the bolts 5, and then the pins 6 are driven into the bottle holes 28A and 28B.

At that time, as described above, the pin tip slope aligns the eccentric bottle holes, so that the second member 2 is aligned with the first member 1.
Move it to the side and press it strongly.

Next, the bolts 4, which were initially lightly tightened, are strongly tightened to complete the joining operation and obtain the joining structure shown in FIG. 2.

FIG. 3 shows a joining state in which end faces of girders 71, 72, 73 and beams 74, which are orthogonal to each other, are joined to the four sides of one through column 7 as another embodiment of the present invention. 4
The figure shows a partially exploded perspective view.

The first point in which this embodiment differs from the previous embodiment is the structure of the joining fitting 75.

That is, as shown in the figure, the shape and dimensions of the two faces 76 and 77 of the backing plate bent at right angles are the same, and the penetration plates 78 and 79 are provided on each face, respectively, forming a plane symmetrical shape.

The second difference is a measure to prevent mutual interference between the uneven structures formed on the end faces of adjacent girders or beams.

That is, as shown in FIG. 4, the lower halves of the left end protrusion 81 and the right end protrusion 82 of the girder 72 are removed, leaving only the upper half, while the left end protrusion 83 of the beam 74 The upper part of the right end protrusion 84 corresponding to the remaining part of the girder 72 was removed, and the combined remaining parts of the girder 72 and the remaining parts of the beam 74 in the joined state were carved on the ridge 85 of the through column 7. It is intended to fill one cavity.

Similarly, the lower half of the girder 71 is removed like the girder 72, and the upper half of the girder 73 is removed like the beam 74.

FIG. 5 shows a single girder 9 as yet another embodiment of the present invention.
The partially exploded perspective view of the T-shaped joint structure in which the ends of two girders 91 and 92 are joined by abutting against each other on both left and right sides of the ends of the figure is shown.

This embodiment differs from any of the previously described embodiments in that the joining metal fittings 91 and 92 are used on one side of the girder 91.92.
This is the structure of 3.

That is, the backing plate 94 has a straight planar shape, and penetration plates 96 and 97 are provided on both sides of the portion that contacts the end surface 95 of the girder 9, and two adjacent corners of the T-shaped girder 9, 91 and 92 are provided. It faces the joining fittings 98 and 99 attached to the.

Each of the penetration plates 96 and 97 has a bottle hole drilled therein, and bolt holes are provided on both upper and lower sides of the penetration plate mounting position of the backing plate, similar to the above-mentioned joining fittings.

In FIG. 6, as another embodiment of the present invention, a girder beam 101 is attached to the top of a column 100. A partial sectional view of a column three-way girder joint structure in which girders 102 and 103 are joined on three sides is shown.

This embodiment is different from any of the embodiments described above in the structure of the joining fittings 104 used on one side of the beam 101 and the girder 103.

That is, the backing plate 105 has a straight planar shape, and the support plate 105 has a straight planar shape, and the
A penetration plate 106 is provided at the part that comes into contact with the side surface of 03, and bolt holes 107 for individual attachment with bolts are provided on the other side.
is perforated.

Therefore, the beam 101 constitutes the first member, and the girder 103 constitutes the second member.

Note that the joining fitting 108 used at one corner has the same structure as the fitting 3 shown in FIG. 1, and the joining fitting 109 used at the other corner is the same as that shown in FIG. It has the same structure as the metal fitting 75 shown.

According to the present invention, the joining is completed by simply inserting the penetrating plate into the pre-cut groove, driving the pin into the pin hole, inserting the bolt into the bolt hole, and tightening, so it depends on the skill of the worker. Therefore, a bonded structure with consistent quality can be obtained extremely easily and in a short time.

Further, according to the present invention, since the cut groove is formed in the horizontal direction, that is, along a plane parallel to the neutral plane of the second member, the strength against tension, compression, and bending of the second member is reduced. There is no lateral force or torsion on the second member, and the pair of joining metal fittings fixed to both left and right sides and the uneven fitting portion formed on the end face absorb this force, making it extremely rigid. An excellent bonding structure can be obtained.

Furthermore, the center position of the pin hole of the second member and the center position of the pin hole of the penetration plate are made eccentric, and by driving the pin, the two centers are made to coincide, and the end surface of the second member is strongly pressed against the first member. In this case, the joint can be easily and firmly tightened, resulting in a more robust structure.
