Description

[Detailed explanation of the idea] This invention relates to a flat roof structure in a wooden frame building.

Traditionally, the roofs of wooden framework buildings were exclusively gable-shaped or hip-shaped, but flat roofs may be preferred in the future.

In addition, the applicant has standardized the structure of each part of the frame structure of wooden buildings in general, and all processing of joints, butt ends, joints, etc. is performed centrally in the factory using σ) machines, and at the construction site, We have already proposed a new invention and idea regarding a wooden frame construction method that allows for the easy assembly of high-quality wooden buildings simply by joining these processed members using joining metal fittings.

The purpose of the present invention is to provide a flat roof structure of a wooden frame structure that uses the above-mentioned new inventions and ideas to standardize the number of parts required for the entire building and the joint structure, thereby increasing the machining rate in factories. It's about doing.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a partial perspective view of an embodiment of the present invention, FIG. 2 shows an exploded perspective view of the first color section, and FIG. 3 shows an exploded perspective view of the section 2 in FIG.

Girders 2゜3 supported on the columns 1...1 on the outer periphery of the frame structure
are orthogonal to each other at the corner, but one of the girders 2 is extended outward from the corner pillar to provide a girder nose 4.

Also, a plurality of arms 5...5 are joined to the two outer surfaces of the girder 2 at appropriate intervals, and arms 6...6 are similarly joined to the outer surface 3A of the other girder 3. , Arms 5...5 and 6
...Cover each end surface of 6 with fascias 7 and 8.

The girders 2 and 3 formed in this way, the girder nose 4, and the armrest 5
... 5, 6... 6 and the fascia 7, 8, the roof is completed.

Figure 2 shows an exploded perspective view of the peak.

A recess 21 is formed at a predetermined position on the inner surface of the girder 2, a dowel hole is bored in the center of the recess 21, and a dowel 9 is inserted through the recess so as to protrude from the inner surface.

The left and right ends of the end face of the other girder 3 are removed to form a rectangular convex portion 31.
A dowel hole 32 is formed in the center of the dowel hole 32 so that the protruding part of the dowel 9 penetrates therethrough and the convex part 31 and the recess 21 fit together.

In addition, a horizontal cut groove 33 is cut along the neutral plane at the end of the girder 3, a bolt hole 34 parallel to the cut groove 33 is bored, and a bolt hole 34 is drilled in the end perpendicular to the cut groove 33. Drill two bottle holes 35° 35 on the left and right that open on the top surface.

The joining fitting 10.10 is a backing plate 10 bent in an L shape.
This is a metal fitting in which a penetration plate 102 is integrally formed on one side of the mountain side of 1. A bottle hole 103 is bored in the penetration plate 102,
1. It has a structure in which bolt holes 104 and 105 are bored on each side.

When using this joining fitting, the penetration plate 102 is inserted into the cut groove 33 from both left and right sides, and both fittings 10 and 10 are clamped to the ends of the girder 3 with the bolts 11.

In addition, at the same time as the attachment of the metal fittings, the dowel 9 is inserted into the dowel hole 32, and the recess 21 and the convex portion 31 are fitted.

After that, the metal fittings 10, 10 are firmly fixed to the girder 2 with the bolts l 2, 12, and then the pins 13.13 are driven from the pin holes 35.35 of the girder to the pin holes 103, 103 of the joining metal fittings. .

At this time, if the positions of the pin holes 35 of the girder and the pin holes 103 of the metal fittings are properly formed in advance, the girder 3 can be strongly pushed against the girder 2 by driving the pin 13, and the joint structure can be tightened. can.

After driving pin 13, Pol) 11.11 and Natsu 14
゜The joining work using the metal fittings is completed by strongly tightening 14.0 Fig. 3 shows an exploded perspective view of the structure in which the girder 15 and the arm 5 are joined to both the inner and outer sides of the girder 2 shown at the mouth in Fig. 1. .

In this case, four metal fittings 10, which are the same as those shown in FIG. 2, are used to support the arm 5 in a cantilevered manner.

That is, the base end of the arm 5 also has dowel holes (not shown in FIG. 2), cut grooves 51, and bolt holes 52, as in the girder end.
, pin holes 53, 53 are formed, and the dowel 9A is inserted through the dowel hole so that only one end thereof protrudes from the inner surface of the girder 2.

When assembling this, attach the metal fittings 10, 10 to the arm 5, attach the metal fittings 10, 10 to the girder 15, then join the arm 5 and the girder 15 to the girder 2, and first, attach the metal fittings 10, 10 with the poles 12, 12. ...Tightly fix 10 to digit 2.

Next, pins 13...13 are driven in to tighten the joint ends, and then bolts 11...11 are again strongly tightened to complete the work.

In the present invention, the joint structure that connects girders and girders or girders and arms is the frame structure of the wooden building, such as columns, girders, beams,
Since it is exactly the same as or similar to the joint structure that joins horizontal members such as the trunk frame, the shapes and dimensions of the wood and metal fittings parts, as well as the processing of the butt ends, are common, making the machining in the factory more efficient. This makes it possible to further promote the standardization of the number of parts.
