Description

[Detailed description of the invention] The present invention relates to a device for joining building materials made of wooden blocks;
This invention relates to a device for joining horizontally tilted platforms such as trunk inserts and foundations.

In conventional wooden frame buildings, various methods of working were used 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 join girders together.

The end faces of the horizontal second members 2, 2 are joined to both side surfaces 11, 12 of the horizontal first member 1, forming a cross-shaped joint.

Both the first member 1 and the second members 2, 2 have shallow central grooves 13, 13 and 2 along the longitudinal direction on both upper and lower sides.
1.21.

This is useful when constructing intermediaries such as lintels and water pipes.
Not only is it useful, but it is also effective in distinguishing between upper and lower surfaces.

At the pulley position of the first member 1, rectangular recesses 14, 14 are formed into which the entire width of the end face of the second member fits.

The depth of this recess is 100 mm x 1 in cross-sectional area of the member.
In the case of 00 mm, it is about 10 to 15 mm.

A dowel hole is drilled in the center of this recess 14, and a dowel hole 15 is inserted therein.
At the same time, dowel holes 22 are also bored in the end surfaces of the second members 2, 2, and the dowels 15 are fitted therein.

Furthermore, for example, L-shaped fastening is performed by clamping metal fittings 3, 3 with bolts on both left and right sides of the end of the second member, and
The bent portions are clamped to both left and right side surfaces of the first member with bolts to connect both members.

At that time, necessary holes among the reference holes 16° 23...23 that are drilled at predetermined positions in each member 1.2 can be enlarged and made into bolt holes using a drill with a guide part. .

Further, the reference hole 17.17 that is drilled at a predetermined position on the upper surface of the first member 1 can be similarly enlarged and made into a dowel hole, and the dowel can be inserted and a through post can be planted on the hole. .

Note that the cut lines 24 of the saw are provided in the vertical direction on both the right and left ends of the end surface of the second member 2, and in the horizontal direction passing through the center, as will be explained in later examples. This is for accurately and easily performing part deletion work.

Figure 2 shows girders 5 and 6 that are orthogonal to each other with the through-pillar 4 as the center.
．． 7 is an exploded perspective view of an embodiment in which the present invention is applied to a joint structure for joining a beam 7 and a beam 8.

This embodiment differs from the previous one in particular in that part of the end face of the second part 5, 6, 7.8 is removed along the saw line 24.

In other words, girder 5 and girder 7 are the lower half 51.71 of both left and right ends.
On the other hand, upper halves 61 of both left and right ends of the beam 6 have been deleted, and portions 81 of the beam 8 corresponding to the upper halves of the beams 5 and 7 have been deleted.

Therefore, in the joined state, the left and right end portions of the second members adjacent to each other do not interfere with each other.

Also in this embodiment, there are dowels 41, 42, 4 on the first member.
3 is provided and fitted into the dowel hole of the second member, and the respective members are tightened using metal fittings, as in the previous embodiment.

According to the present invention, the position of the dowel, the cutting line of the saw, the recess on the side of the first member, the reference hole for fixing the fastener, etc. are standardized, and all can be processed in the factory. The number of on-site construction days and amount of work for wooden buildings can be significantly reduced.

In addition, the position of the dowel, the cutting line of the saw, the recess on the side of the first member,
Since the holes for fixing the fasteners are made symmetrically, it is possible to use common parts such as beams and girders, which reduces the number of types of parts.

Further, in the present invention, the distance between the fitting surfaces of the recess of the first member or the adjacent other member and the convex portion of the second member is the second.
Since it is approximately equal to the opposite side of the end face of the member and is much larger than the conventional tenon, it is possible to obtain a stable and robust joint structure that is strong against lateral loads such as torsion and bending.
