Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a skeleton structure provided in a corner portion of a planar rectangular skeleton formed of vertical columns in wooden construction and cross beams connecting them. The present invention relates to a strut fastening device for a wooden building that reinforces the structure.

[Conventional technology]

The wooden construction is a shield structure, and each part of the wall forms a quadrangle, but it is unstable with respect to the lateral force caused by wind and earthquake, so diagonal members, that is, braces and orientations, etc. Used to reinforce. The foundation and base of a conventional wooden building are made extremely strong by the above-mentioned reinforcing members and anchor bolts. Compared to this, the skeleton near the roof is weak. It is due to the fact that the roof tiles are quite heavy, the use of long pillars that reach the roof is rarely used, and that the wooden structure is assembled by grooves and mortises. There is a drawback in that it is necessary to make the column thicker by strengthening these parts and to use a complicated and expensive reinforcing member.

[Problems to be solved by the invention]

Therefore, the present invention avoids the conventional drawbacks of wooden buildings, keeps the weight of the roof in good balance, is strong against strong winds such as typhoons and vibrations due to earthquakes, and can strengthen the frame with a simple structure. It is an object of the present invention to present a supporting strut fastening device.

[Means for solving problems]

The above-mentioned problems are provided in the corner portions of the vertical rectangular frame formed from the vertical columns in the wooden construction and the cross girders connecting them, and in the wooden structure column fastening device for reinforcing the frame structure, A pillar fastening metal fitting that can be fixed to the pillar and the cross girder is composed of two metal plate fitting members, a pivot part that allows them to pivot along the pillar outer edge, and a cross girder in each end region of the fitting member. The upper and lower clamping members are angled to fit each other, the length of each clamping member is longer than the lateral width of the cross beam, and one strut is fastened to connect the upper and lower clamping members. At least one on the metal fittings
By a fastening device for a wooden building, a plurality of fastening bolts are attached, and vertical struts located diagonally to each other in a plane rectangle are stretchably adjusted by tension means provided between the fastening bolts. Will be resolved.

〔Example〕

 The present invention will now be described in detail with reference to the illustrated embodiment.

It is premised that the framework of a wooden building is made of wood and has a substantially rectangular parallelepiped shape, and that its wall body is appropriately provided with a diagonal member as usual.

FIG. 1 shows a strut fastener 1 of a strut fastening device according to the present invention.
Is shown before it is attached to the corner of a wooden building. The column fastening metal fitting 1 has two metal fitting members 2 and 3 made of a metal plate. A pivot portion 4 is formed so that the metal fitting members 2 and 3 can be bent at a right angle at a corner portion, and a bolt 5 and a nut 6 are used to fix the pivot portion 4. In the respective end regions of the metal part 2 or 3 opposite the pivot part 4, the upper and lower clamping members 12, 13 and 12 ', 1 angled at right angles, i.e. bent or welded.
3'is provided.

As can be seen from FIG. 2, the metal fitting member 2 conforms to the vertical width of the cross beam 9, and the holding members 12 and 12 ′ are longer than the horizontal width of the cross beam 9. The metal members 2 and 3 and the upper and lower holding members 12, 13 and 12 ', 13' respectively have transverse beams 9 and 10.
There are provided an appropriate number of holes 14 for fixing with, for example, nails. If the cross girder 10 has a different vertical width from the cross girder 9, the metal fitting 3 is made to fit the cross girder 10 and, at that time, a step difference occurs at the pivot part 4.

A hole (not shown) for connecting the upper and lower clamping members is formed at the free end of each clamping member 12, 13 and 12 ', 13', and the fastening bolt 15 is tightened through the hole. In FIG. 2, since the upper and lower clamping members do not overlap each other, two fastening bolts 15 are required. However, depending on the case, the clamping members may be extended and overlapped so that one fastening bolt 15 is tightened. You can also do it.

When the clamping members 12, 13 and 12 ', 13' are tightened with the fastening bolts 15, the upper sleeve 17 and the lower sleeve 18, which have a diameter slightly larger than the shaft diameter of the fastening bolts 15, form the upper clamping members 12 and 13 with each other. It is inserted between the sandwiching members 12 'and 13' at the lower part and the lower part. Further, between these upper and lower sleeves 17 and 18, a T-shaped connecting member 20 having a long hole 20 'having substantially the same width as the axis of the fastening bolt 15 is inserted. The T-shaped connecting member 20 further has a hole 20 ″ in the T-shaped leg portion, and a tension bar made of an iron round bar or a stainless round bar bent in a U-shape in the hole 20 ″.
21 can be hooked.

FIG. 3 shows an example in which the strut fastening device according to the present invention is actually applied. 4 vertical columns 8 and cross girders 9 and 10
Of the four strut fasteners of the four strut fasteners fixed to the corners of the skeleton assembled into a plane square by means of the strut fasteners 1,1 and 1 ', 1' that are diagonally located
They are connected to each other via a tension bar 21 and a turnbuckle 22. Therefore, it is determined whether the screws provided at the free ends of the tension bars 21 have mutually opposite pitches, or whether the inner screws formed on the turnbuckle 22 have opposite directions. When the frame of the wooden building is erected, the turnbuckle 22 can be tightened or loosened to easily adjust the frame.

In FIGS. 1 and 2, the upper sleeve 17 and the lower sleeve 18 have substantially the same length, but in order to raise or lower the position of the T-shaped connecting member 20, that is, the position of the tension bar 21. The length ratio of the upper sleeve 17 and the lower sleeve 18 can be changed.

The method of tensioning as shown in FIG. 3 can be set at a frame near the roof or between the ceiling and the floor of the first floor in the case of a two-story wooden building.

[Effect of device]

Since the present invention has the above-mentioned configuration, the horizontal girders and vertical columns of the frame of a wooden building can be always held in a good balance, and it is resistant to a large external force, for example, strong wind such as typhoon or vibration due to earthquake. It is possible to save wood, and it is possible to obtain the advantage that the 3-5 minutes columns are now 3/3 minutes and the 3/3 columns are 3 inches in terms of strength. Further, when the skeleton of the house stands up, it is possible to easily correct the force applied to the skeleton by adjusting the turnbuckles located on the diagonal line.
