Description

Description: TECHNICAL FIELD The present invention relates to a house capable of increasing the strength of the frame base by sharing the horizontal force applied to the ridge truss with the multiple columns forming the frame base of the house. Frame structure.

[Background Art] The building trusses that form the ridge of the house are placed on the roof beams that span the columns. Conventionally, such a building truss has been started up only by fixing its lower end portion to a roof beam. Therefore, when horizontal force such as cross wind is applied to the ridge truss, the horizontal force is transmitted to the column closest to the ridge truss through the roof beam, resulting in uneven distribution of the horizontal force of each column. However, there is a problem that the strength and rigidity of the skeleton itself is reduced. This tendency is remarkable especially when the truss and the pillar are misaligned.

[Object of the Invention]

The present invention is based on the fact that the upper chord member of a ridge truss and the upper end portion of a column arranged away from the ridge truss in a direction perpendicular to the longitudinal direction of the ridge truss are connected by a connecting frame material. The purpose of the present invention is to provide a frame structure of a house that can increase the strength of the frame by dispersing the horizontal force applied to the pillars on each column to bear the load.

Further, the skeleton base 4 is formed on the cloth foundation B in this example as a skeleton of a horizontally-long rectangular total two-story house.

On the cloth foundation B, there are four column rows in which the columns 2 which are the through columns are juxtaposed in the lateral direction at substantially equal intervals and are vertically spaced from each other.
A row is provided. Further, in this example, the column rows located in the middle are slightly offset from the center. Each pillar 2 is the cloth foundation B
It is fixed by being connected to a base metal fitting (not shown) which is fixed to, and stands up on the cloth base B.

The roof beam 3 is bridged between the pillars 2 and 2 adjacent to the upper end of the pillar 2. In this example, the roof beam 3 has an outer beam 3A having an I-shaped cross section arranged on the outer frame of the frame base body 4 and an inner beam 3B arranged inside the frame, and the outer beam 3A and the inner beam 3B are , The contact plates attached to both ends are brought into contact with the side plates of the pillar 2, and the contact plate and the pillar 2
It is fixed to the pillar 2 by bolting the side plate of the.

By vertically and horizontally connecting the columns 2 and 2 by the roof beams 3 and 3, the roof beams 3 form a quadrilateral quadrangular frame 10 with the positions of the columns 2 as corners. Also roof beams 3
... is a combination of three horizontal beam rows E, F and G formed by connecting horizontal roof beams 3 and four vertical beam rows H, J, K and L, which are connected vertical roof beams. A lattice-shaped beam structure is formed by the combination.

Further, an auxiliary beam 12 connecting the columns 2 is provided at an intermediate position of the height of the columns 2.

Each of the frames 10 ... Has the braces 5, 5 in the diagonal direction thereof.
Are laid horizontally and in a cruciform manner. Therefore, a brace 5 connecting between the diagonal positions C of the quadrangle is attached to the frame base 4.

In this example, the ridge truss 6 is formed for the ridge portion of the dormitory roof, and is a lower chord member 21 slightly longer than the width dimension of the frame base 4.
And the upper chord member 22 which is shorter and smaller than the lower chord member 21 are arranged above and below with a space therebetween, and both ends of the upper and lower chord members 22 and 21 are connected by diagonal members 23 and 23 in a ladder shape A plurality of vertical members 29, 29 and truss members 30, 30 connecting the upper and lower chord members 22, 21 are arranged on the outer frame of the above.

Further, the ridge truss 6 is placed on the roof beam 3 across the vertical beam rows H, J, K and L at approximately the center of the frame base body 4 in the vertical direction. The ridge truss 6 has a roof beam 3 on the lower surface of the lower chord member 21 as shown in FIG.
The seat plate 24 which is aligned and attached to the roof beam 3 is fixed to the roof beam 3 by bolting or the like, and is attached upright on the upper surface of the frame base 4.

Two joints R at which the upper chord member 22 and the diagonal member 23 intersect,
A seat plate 27 having a mounting hole 26 is attached to the front surface of S.

Further, the frame base 4 has intersections M, N, P, Q, which intersect the vertical beam rows H, J, K, L of the transverse beam row F located in the middle, respectively.
That is, a mounting plate 32, which is located on the diagonal position C of the skeleton base 4 and has a mounting hole 31, overhangs the upper surface of the roof beam 3 and is attached to the upper end of the pillar 2.

In this example, the connection frame member 7 is a first connection frame member 7A that connects the joint R of the ridge truss 6 and the intersections M and N of the frame base body 4 and the second connection frame member 7A.
The connection frame member 7B and the third connection frame member 7C and the fourth connection frame member 7D that connect the intersections P and Q with the connection frame member 7B are provided.

Each connection frame member 7 is provided with side plates 36 and 37 facing the seat plate 27 and the mounting plate 32 at both ends of a frame member 35 having rigidity such as a channel member. The side plate 36 is provided with a bolt hole 39 aligned with the ridge truss mounting hole 26 and provided through the side plate 37, and the side plate 37 is provided with a bolt hole 40 provided at the same position as the mounting hole 31 of the frame base 4 through the side plate 36. .

Each of the connecting frame members 7 ... has the side plate 36 as the seat plate 2 of the ridge truss 6.
7 is fixed to the end portion of the upper chord member 22 of the ridge truss 6 by bolting with a bolt that inserts both the overlapping mounting hole 26 and the bolt hole 39 into 7, and the side plate 37 is mounted on the mounting plate 32. Mounting and mounting hole 31, bolt hole 40
The other end is fixed to the skeleton base body 4 by tightening a bolt passing through. Therefore, the connection frame member 7 is separated from the upper chord member 22 of the ridge truss 6 and a diagonal position C of the frame base body 4 to which the brace 5 is attached and in a direction perpendicular to the longitudinal direction of the ridge truss 6 from the ridge truss 6. The horizontal beam row F to be arranged
It is possible to obliquely connect the upper ends of the pillars 2 which are interposed between the pillars 2 and the ridge A with the vertical members 29, the roof beams 3 and the connecting frame members 7 to form a truss body in the shape of a right triangle. It Therefore, a horizontal force such as a side wind acting on the ridge truss 6 can be transmitted to the brace 5 via the connecting frame member 7.

However, the strong wind or the like blown toward the ridge portion A acts on the ridge truss 6 as a horizontal force. Such a horizontal force is transmitted to a diagonal position C of the skeleton base body 4 to which the brace 5 is attached, the majority of which passes through the connection frame member 7, and is further dispersed and transmitted to the columns 2 through the brace 5. Therefore, unlike the conventional structure, horizontal force is not concentrated and applied to a small number of columns 2 near the ridge truss 6, and the frame base body 4 has increased frame strength against horizontal force.

The connection frame member 7 includes the first and fourth connection frame members 7A, 7D,
Alternatively, either one of the second and third connecting frame members 7B and 7D may be omitted so that the horizontal force is transmitted by the two connecting frame members 7 and 7, and the ridge truss 6 is for a gable roof. It can be formed, and the present invention can be modified into various aspects.

〔The invention's effect〕

The ridge truss is fixed to a frame base having columns and roof beams connecting the upper ends of the ridge trusses, and horizontal braces are installed between the diagonal positions of the ridge trusses. Since the upper end of the pillar arranged away from the ridge truss in the direction of the right angle is connected by the diagonal connecting frame member, the horizontal force acting on the ridge truss is passed through the diagonal connecting frame member and the brace. Since it is possible to share a large number of columns, the frame strength and rigidity of the frame base can be increased in combination with the use of the diagonal connection frame material, and the durability of the house can be improved.
