As a result members are unified, and a cost is reduced, and the free degree of ceiling composition is increased, and the roof truss of high precision can be formed.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides a framework structure for a roof frame using climbing beams, even when a bundle cannot be erected at the ridge. The present invention relates to a frame frame structure of a ridge part that can bridge the roof frame and can cope with variations in the distance between the bundles sandwiching the ridge part.

(Conventional technology) Conventionally, in order to form a sloping roof for a house, the roof structure was constructed by raising bundles from the lower beams and passing a gassho member extending from the ridge to the eaves at the top of the bundles. was forming.

[Problem to be solved by the invention]

However, in recent years, with the diversification of house structures, at the tips of multiple bundles erected on wooden beams, the main building has a horizontal frame, while the other has a frame that is slanted to match the slope of the roof. For example, it is becoming common practice to form a roof assembly consisting of a sloping roof in the gussho style by combining and connecting the climbing purlins.

On the other hand, as a standard for the plan dimensions of a house, Figure 9 (a)
The so-called single grid system, in which the distance between the centers of pillars b is the basic module P, as shown in FIG. There is a system. Therefore, when the bundle d is erected on the axis of the pillar, in the case of a double grid system, each purlin and climbing purlin will be longer by the cross-sectional dimension f of the pillar than in a single grid system. becomes.

Furthermore, in the case of a double grid, when only the lower part of one sloped roof is partitioned into two rooms as shown in Figure 9(C), the gable side dimensions of the house are smaller than those in Figure 9(b). Furthermore, the column will be elongated by the insufficient dimension, and if this increase is absorbed between the bundles that sandwich the ridge a, the horizontal length of the climbing beam C that forms the ridge will become even longer, resulting in IP+
-2N length. In this way, in the case of a single grid system, a double grid system, and a double grid system, the length of the beam materials differs depending on the difference in partitions, resulting in a variety of beam lengths, which complicates design and construction. Management is also not easy. In addition, in modern houses, the ceiling beams are separated due to reasons such as windows that guide sunlight into the room through the roof, and storage rooms that are installed in the attic. In many cases, as a result, the ridge cannot be supported by the bundle material.

The inventor completed the structure of the present invention in order to comprehensively solve the various problems mentioned above.

The present invention is based on installing a gassho member that forms the ridge part between a pair of beams parallel to the ridge part so that the length can be adjusted with the beam member, and without supporting the ridge part with bundles. The object of the present invention is to provide a frame frame structure for a ridge part that can form a roof frame accurately and reliably even when the dimensions of the beams differ, and that can solve the above-mentioned problems.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the frame frame structure of the ridge part of the present invention is a frame frame structure of the ridge part in which a sloped roof is formed on both sides of the ridge part. , a pair of beams are erected parallel to the ridge between the bundles arranged on both sides of the ridge and parallel to the ridge, and a pair of beams are erected parallel to the ridge, and a Mounting brackets each having a mounting piece extending obliquely upward on the slope of the sloping roof are each fixed, while a plurality of through holes are arranged in parallel in the length direction of the mounting piece, and between the facing mounting pieces, A pair of climbing beam members that intersect at the slopes of the intersecting sloped roofs are joined together in advance, and a gassho member is attached using a bolt passing through at least one of the plurality of through holes.

[Effect]

In the present invention, a pair of beam members is constructed between the bundle members arranged in parallel with the ridge, and a gassho member including a pair of climbing members that intersect at the slope of the sloping roof is attached to the beam members. The ridge can be formed without supporting the ridge from below.

Also, since the mounting bracket and gassho material that are fixed to the beam are attached using a bolt that passes through at least one of the multiple holes provided in the mounting bracket, the spacing between the opposing beams may be different. Even in this case, the gassho materials can be installed across the beams to form the ridge of the sloping roof.

As shown in FIG. 8, the beam members 3.3 may be adjusted by shifting the mounting pieces 7.7 on both sides at the same time and by the same dimension, thereby attaching the gassho members 5. In this case, the adjustment of the beam member 3 in the height direction may be omitted.

〔Effect of the invention〕

Like a ridge, the frame structure of the ridge of the present invention is such that a beam is passed parallel to the ridge between the bundles placed on both sides of the ridge, and a mounting bracket has a mounting piece extending diagonally to the beam. In addition to fixing the roof, the structure is such that a gassho material that can form a ridge is attached to the mounting piece, so the ridge can be formed without supporting it with bundled materials, increasing the degree of freedom in configuring the ceiling of the house, and allowing for a variety of designs. It can contribute to the

In addition, gassho materials have a structure in which they are installed using bolts that pass through one of the multiple through holes provided in the mounting piece in the length direction. Gassho materials can be installed between beams even if the spacing is different, and a single gassho material is sufficient even if the room partitions are different in a single grid system, double grid system, or even double grid system. Therefore, it is possible to promote the unification of components and reduce costs.
