Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building base arranged along the upper surface of a foundation.

[0002]

2. Description of the Related Art Generally, as a building base fixed along an upper surface of a foundation made of concrete, a base made of wood having a rectangular cross section is widely used even in conventional construction methods and prefabricated construction methods. The base made of wood is fixed by anchor bolts standing upright on the foundation. Also, pillars and studs are erected through the base.

However, conventional wood bases have
There were the following problems. (1) It is easily damaged by termites and easily corroded by moisture. (2) By repeatedly absorbing and releasing moisture, the cross-sectional dimensions of the base change over time, which causes distortion in the building. (3) Since it is heavy, it is not suitable for workability at the site and tends to increase the cost. (4) Since both the portion that supports concentrated load, such as directly below the pillar, and the portion that does not support concentrated load have the same cross section, the weight becomes large and the material of the base is wasted. (5) Since the processing accuracy is low and the dimensions are easily changed, it is difficult to form a modular unit and the workability of the building is deteriorated. (6) It is easy to lead to environmental damage due to logging.

[0004]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems in the prior art, is free from termite feeding damage, corrosion due to moisture or dimensional change, is lightweight, and has improved processing accuracy and workability. While having the required strength as a structural material, it also provides a favorable building base from the environmental perspective,
This is an issue.

[0005]

In order to solve the above-mentioned problems, the present invention applies an extruded profile of an aluminum alloy to a building base, and at the same time, anchor bolts and the like penetrate and loads at least in the vertical direction are concentrated. It was made with the idea of arranging a vertical partition wall in the part to be added.
That is, the building base (Claim 1) of the present invention is a building which is arranged along the upper surface of the foundation and is formed of an extruded profile made of one or more aluminum alloys fixed on the foundation by bolts. A foundation, at least
In the portion fixed to the foundation with bolts, the outer diameter has a substantially rectangular cross section and has a hollow portion with a similar shape to the cross sectional shape along the longitudinal direction, and near the center of the cross section of the hollow portion in the width direction. A pair of vertical partition walls are formed at positions sandwiching the bolt.
The base includes both a first building base described below and a second building base described later. Further, the first building base (claim 2) in the present invention is for a building which is arranged along the upper surface of the foundation and is formed of an extruded profile made of an aluminum alloy fixed on the foundation by bolts. A base, which has a hollow portion having a substantially rectangular outer cross section and a shape similar to the cross sectional shape along the longitudinal direction, and a position where the bolt is sandwiched near the center in the width direction in the cross section of the hollow portion. In addition, a pair of vertical partition walls are formed. The bolts include not only anchor bolts, but also bolts that are screwed into connection fittings that fix columns.

[0006] According to these, since the building base is formed by the extruded profile of aluminum alloy, the base has a stable cross section, shape and strength for a long period of time without corrosion by termites, corrosion by moisture or dimensional change. . Further, the weight can be reduced, the processing accuracy is high, the workability of the building can be improved, and it is preferable from the environmental viewpoint. Moreover, the outer shape has a rectangular cross section and a hollow section having a rectangular cross section along the longitudinal direction, and by forming a pair of vertical partition walls at a position sandwiching the bolt near the center in the width direction of the hollow section, 3 Two hollow parts are formed. For this reason, for example, a pair of partition walls will be arranged near the portion through which the anchor bolts standing from the foundation penetrate, and buckling deformation of the base due to the tightening force of the bolts can be easily and reliably performed. It can be prevented. Therefore, the required strength as a structural material can be reliably imparted. The longitudinal direction is the same as the extruding direction of the extruded profile forming the base. Further, the width direction refers to a horizontal (width) direction in a cross section orthogonal to the extruding direction of the extruded profile, which is the indoor or outdoor direction of the base.

On the other hand, a second building base of the present invention (claim 3) is a base body which is arranged along the upper surface of the foundation and is formed of an extruded profile made of an aluminum alloy, and a longitudinal direction of the base body. A base for a building, which is fitted at a predetermined position in the direction and is fixed to the foundation together with the base body by a bolt made of the same extruded shape as described above, wherein the base body has an opening. The section has a substantially U-shaped cross section with an opening toward the foundation side, and the reinforcing member has a hollow section having a substantially rectangular outer cross section and a shape similar to the cross section along the longitudinal direction, and A pair of vertical partition walls is formed near the center in the width direction, sandwiching the bolt.

Also by this, there is no fear of termite damage, corrosion due to moisture, dimensional change, and distortion of the building, and the base itself can be made lighter in weight, the processing accuracy is high, and the workability of the building is improved. Moreover, the reinforcing material is arranged only in the portion where the anchor bolt penetrates and the pillar is erected and the load in the vertical direction is concentrated, and the bolt near the center of the hollow portion of the reinforcing material in the width direction is sandwiched. A pair of vertical partition walls are arranged in the vertical position. As a result, three hollow parts are built in. Therefore,
Even if it receives a concentrated load due to tightening of anchor bolts, etc., it can be sufficiently supported, so that the building base can be further reduced in weight.

Further, according to the present invention, the pair of vertical partition walls formed in the hollow portion of the building base or the reinforcing material is more than the interval for evenly dividing the building base or the reinforcing material in the width direction. Also included is a building base (claim 4) located close to both sides of the bolt. According to this, since a pair of partition walls are arranged so as to sandwich these bolts on both sides of a portion that the anchor bolt penetrates and a bolt that is screwed with a connecting fitting inserted at the lower end of the pillar, the anchor bolt Even if a concentrated load such as tightening is applied, the load can be reliably supported without causing deformation such as buckling.

Further, in the present invention, the distance (inner) between a pair of vertical partition walls formed in the hollow portion of the building base or the reinforcing member is 1.1 to the outer diameter of the bolt.
It also includes a building base (Claim 5) in the range of 2.5 times. According to this, even if the base receives a concentrated load due to tightening of the anchor bolts, the load can be reliably supported without buckling. If the distance between the pair of partition walls is less than 1.1 times the outer diameter of the bolt, it becomes difficult for the bolt itself to penetrate.
When it exceeds 5 times, the horizontal piece at the upper end of the building base or the reinforcing material is deformed, and accordingly, the partition wall may start to buckle. In order to prevent these, the distance between the pair of partition walls is set within the above range. Distance between a pair of bulkheads
The lower limit of (inner) is 1.2 to 1 of the outer diameter of the bolt.
When the range is three times or more, the penetration of the bolt becomes easier, and due to contact with the bolt at the time of penetration,
There is also no risk of damaging the building base or reinforcements.

In addition, according to the present invention, when the building base is fixed on the foundation by the bolt and the nut screwed to the bolt, a washer is sandwiched between the nut and the upper surface of the base. , The width dimension of the washer is larger than the distance between the pair of partition walls.
(Claim 6) is also included. According to this, the tightening force of the bolt via the washer can be reliably received by the pair of partition walls, so that the deformation of the base can be more reliably prevented.

Vertical partitions 7a and 7b are formed at positions sandwiching 20. Therefore, when fixing the base 1 on the cloth foundation K, the bolts 20 and the nuts 22 can be firmly fixed, and it is possible to prevent the base 1 from buckling and deforming due to a strong tightening force. Further, the hollow portion 6 is not evenly divided, and the bolt 2
By arranging the pair of partition walls 7a and 7b near 0, the effect of preventing the deformation can be surely obtained.

Moreover, the distance w between the pair of partition walls 7a, 7b
Is set in the range of 1.1 to 2.5 times the outer diameter d of the anchor bolt 20 penetrating the hollow portion 6c and the like, and the width of the washer 21 is made larger than the distance w. Therefore, even if a vertical concentrated load is applied by the anchor bolt 20 and the nut 22, the vicinity of the center of the horizontal piece 2 at the upper end is deformed downward, and the partition walls 7a, 7b and the vertical pieces 3, 4 are buckled and deformed. The situation can be reliably prevented. Moreover, as will be described later, similar supporting strength can be exerted even when a vertical concentrated load caused by vertically suspending the pillar H on the horizontal piece 2 is received. Therefore, the building bases 1 and 1a have a small weight and have a required strength as a structural material for a building.
