Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a partially sloped beam material that allows a double-sided roof to be constructed easily and easily (expanded) to expand the living space of a house.

[Problems to be solved by conventional techniques and inventions] Conventionally,
Roof construction work is carried out by sequentially lifting and erecting the main house, nose purlin, etc. along with the ridgepole using bundles of beams at the top of the main body of the house, which increases the number of times each member is lifted and the work This lengthens the time, reduces construction efficiency, and increases construction costs.

Therefore, in Japanese Patent Application No. 63-36418, the present applicant proposed a plurality of mountain-shaped Ramen C-. devised a roof construction method that simplifies the construction work by forming in advance a roof frame structure e that is integrally connected by joint beams d, and erecting this structure between beams f and f at the upper end of the main body of the house. did.

However, although this product can further improve productivity and reduce costs by standardizing the above-mentioned angular Ramen C, it causes a reduction in the degree of freedom in design due to restrictions such as dimensions, and therefore, for example, as shown in FIG. ℃) as shown by the dashed line,
In order to expand the living space in response to the demands of residents, it is necessary to adopt new beam materials for roof support.

The object of the present invention is to provide a partially sloped beam material that is particularly suitable for use in houses with such mountain-shaped rigid frames, allows the construction of double-sided roofs to be expanded with ease and ease of construction, and allows for the expansion of living space.

[Means to solve the problem]

In order to achieve the above object, the partially inclined beam material of the present invention has an inner end fixed to a beam material to which the lower end of the pillar of the Yamagata frame is fixed, in which a gassho beam for forming a double-sided roof is spanned between the upper ends of the pillars. An inclined beam part is integrally provided at the outer end of the horizontal beam part projecting outwardly, the inclined beam part having the same slope as the joining beam and having an upper surface located at a height lower than the slope passing through the upper surface of the joining beam.

[Effect]

The slanted beam part of the partially slanted beam constructed in this way works together with the gassho beam of the Yamagata frame to form the climbing beam part for the roof assembly, and therefore the lower part of the double-sided roof extending from the gassho beam extends from its slope. It can be supported by beams, making it possible to form large double-sided roofs as required.

In addition, the horizontal beam can constitute a floor beam that supports the floor of the upper room together with the beam of the main body of the house to which the partially inclined beam is attached.

[Example] Hereinafter, we will take as an example the case where the partially inclined beam material 1 of the present invention is used to form a large double-sided roof R of a three-story house H illustrated by the dashed line in FIG. One embodiment thereof will be described based on the drawings.

In the figure, a partially inclined beam member 1 includes an inclined beam member 3 integrally provided at the outer end of a horizontal beam member 2, which is inclined along the roof slope of the roof R, and a beam member at the upper end of the house main body Ha of a house H. By fixing the inner end of the horizontal beam part 2 to 15, it is arranged so as to protrude outward from the eaves side.

The frame of the house H is schematically shown in FIG. 1, and beam members 15 are arranged between the middle pillars 14 and the upper ends of the house main body Ha to form the floor beams of the third floor room. Between .15 and 2
The roof R
An upper roof assembly J1 can be formed which supports the upper part of the roof assembly J1.

Note that such a roof bridge body 16 is assembled on the ground, then lifted using a crane or the like, and
bridged between.

The roof frame structure 16 has its lower end attached to the beam material 15.

A pair of left and right roof pillars 25 each having a sloped piece 23 at the upper end of the pillar 22 to be fixed are placed opposite each other with the sloped pieces 23.23 facing each other, and a ridge beam piece 26.26 that slopes on both sides of the ridge is placed between the ends of the roof pillars 25. A chevron-shaped frame 29 is provided with a dogleg-shaped beam 27 spanning over it.

In addition, in this example, there are two Yamagata Ramen noodles arranged in parallel.
3 ridgepole-like joint beams between 9! , Purlin-shaped joint beam 32.33
The roof frame structure 16 is formed by spanning the two and integrating the two.

As shown in FIG. 2, the pillar 22 forms the roof pillar 25 by integrally fixing the inclined piece 23 to the upper end of one flange of a base 35 made of H-shaped steel. A leg portion 36 having a base piece 39 bolted to the beam member 15 at the lower end is formed at the lower end of the leg portion 35 .

The leg portion 36 is formed with a place mounting piece 40A that protrudes in a direction perpendicular to the inclined piece 23, and the base 35 is formed with a beam connecting piece 40B extending in the same direction as the place mounting piece 40A. For installation, piece 40C protrudes.

Further, between each beam connecting piece 40B, there are horizontal connecting beams 41A, 4 which are perpendicular to the inclined piece 23 at a lower place different from the height of the inclined piece 23.
1B are connected, and each of the connecting beams 41A, 41B, together with the place B stretched between the mounting pieces 40A, 40C facing each other, strongly reinforces the upper roof fl&l1 body J1. The beam connecting piece 40B and place mounting pieces 40A and 40C are formed only on the inner side of the house on the pillar 22 located on the verge side.

In addition, both the inclined piece 23 and the doglegged beam 27 have the same cross-sectional shape as H.
The inclined piece 23 and the doglegged beam 27 are connected to form a gassho beam 30 which is made of shaped steel and is supported by the pillar 22 by connecting the tips thereof using a fitting 42.

The partially inclined beam member 1 of the present invention is attached to the beam member 15 that supports such an upper roof assembly J1, thereby forming a lower roof assembly J2 that supports the lower part of the roof aR.

The partially inclined beam member 1 includes a horizontal beam portion 2 whose inner end is fixed to the beam member 15 and projects outward, and an inclined beam portion 3 integrally formed with the outer pot thereof, and in this example, It is arranged in the same vertical plane as the gassho beam 30.

The partially inclined beam 1 is made of I-shaped steel with flanges horizontally provided at the upper and lower ends of the web, similar to the beam 15, and the web IA of the horizontal beam 2 is bolted to the connecting piece 45 protruding from the beam 15. By doing so, its inner end is fixed, and in this example, the upper end of the inclined beam portion 3 is fixed to the gassho beam 3.
