Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an assembly structure for frame members in a wooden structure and a metal fitting used therein.

[Conventional technology]

In general, the framework of a wooden structure is constructed by installing vertically extending columns at predetermined intervals, and placing beams across predetermined portions of these columns horizontally, as well as diagonally extending braces. ing. For example, when connecting another beam in a T-shape to the side surface of a horizontally arranged beam, first, as shown in FIG. A hole 3 is provided on the upper end side of the recess 2.
will be established. Next, a protrusion 5 that can fit into the recess 2 of the beam 1 is provided on the upper end of the end face of the other beam 4, and a protrusion 5 that can fit into the dovetail hole 3 of the beam 1 is provided on the upper end of the protrusion 5. Provide dovetail and tenon 6. Then, the protrusion 5 of the beam 4 is inserted into the recess 2 of the beam 1.
The dovetail tenon 6 of the beam 4 is fitted into the dovetail hole 3 of the beam 1, and the beam is connected to the beam 1 in a 4T cross shape. Furthermore, if necessary, the connection between the beams 1 and 4 is reinforced using bolts, metal fittings, or the like.

[Problem that the invention seeks to solve]

However, in the above method, the beams 1 and 4 are connected by a complex-shaped joint consisting of a hole 3 and a dovetail tenon 6, etc., and a carpenter manually processes this joint to connect the beams, etc. Since the framework members are assembled, there are problems in that dimensional accuracy tends to be uneven and construction takes a long time. Furthermore, since the dimensional accuracy is non-uniform, there is a problem that the shaft assembly yield strength becomes non-uniform and the strength becomes weak. Furthermore, since the recess 2 and the dovetail hole 3 are provided, there is a problem that the missing portion of the beam 1 becomes large and the strength of the beam 1 becomes weak.

The present invention was developed in view of the above circumstances, and by eliminating joints using dovetail holes etc. and assembling with metal fittings, it is possible to improve strength and dimensional accuracy, and to quickly assemble the parts. Another object of the present invention is to provide an assembly structure for frame members that can be easily assembled, and metal fittings used therein.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention surrounds the upper surface and both side surfaces of one of the beams, and attaches to said beam a metal fitting having a U-shaped vertical section and whose side portions are vertically hung on both sides of the ceiling. attachment,
A plate-shaped horizontal piece with a through hole bored therein is extended from one side of the metal fitting in an upright state so as to be perpendicular to the side, and the end face and the upper and lower sides sandwiching the end face are attached to the end of the other beam. An open letter-shaped slit is drilled, and a through hole perpendicular to the slit is drilled in the side surface of the other beam, and with this through hole aligned with the through hole in the horizontal piece, By fitting the slits of the beams into the horizontal pieces, and inserting the rod-shaped fixtures into the through-holes, the frame member is assembled and fixed with one beam and the other beam in a T-shape. The first point is the assembly structure, and a temporary horizontal piece is extended horizontally in an upright state from one side of the metal fitting, which has a U-shaped vertical cross section with side parts hanging down on both sides of the ceiling. The second aspect is an assembly fitting for a frame member in which a hole for inserting a rod-shaped fixing fitting is bored in the horizontal piece.

[Effect]

The structure for assembling frame members of the present invention does not require a carpenter to assemble the beams while sequentially processing them, relying on his experience and intuition, as in the conventional example. It is assembled by using a beam with slits and connecting it with a metal fitting and a rod-shaped fixture. That is, at the end of the other beam connected to the side surface of one beam, a slit with an open end face and a top and bottom side sandwiching the end face, and a through hole orthogonal to the slit are provided. Then, attach the body part of the metal fitting with a U-shaped cross section to one of the beams, fit the slits of the other beam into both horizontal pieces of the metal fitting, and connect the through hole of the other beam and the through hole of the horizontal piece. By inserting rod-shaped fixtures into the respective holes, one beam can be assembled to the other beam in a T-shape. In this case, the assembly work is extremely easy, as all you have to do is align the through-hole of the other beam with the through-hole of the metal fitting, and insert the rod-shaped fixture into both holes, which greatly reduces the construction time. It becomes possible to shorten the length and assemble a frame assembly with excellent dimensional accuracy.

Furthermore, since metal fittings are used, the strength of assembling the beams together can be improved. Furthermore, by planting a vertical piece with a through hole from the ceiling of the metal fitting, this vertical piece can be used to attach other pipe columns, etc. to the top surface of the connecting part of the beams connected in a T-shape. It will be possible to plant.

Next, the present invention will be explained in detail based on examples.
