Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Technical Field] The present invention relates to a column base support used in the construction of a house or the like.

[Background technology]

Conventionally, as a structure for fixing a hollow column to a building structure such as a foundation, an anchor bolt 2 embedded in a building structure 1 in advance has a grooved cross section, as shown in FIG. 9 and FIG. There is one in which the column base support 8 is tightened and fixed with a nut 5, and the lower g6a of the column 6 is fitted into this. Note that the column 6 is fixed to the column base support 8 with bolts (not shown) as necessary.

However, in this structure, both flanges of the column pedestal support 8 stand up vertically, so when fitting the lower end 6a of the column 6 to the column pedestal support 8, the position must be adjusted accurately. Cannot be mated. Therefore, extra effort was required to fix the lower end 6a of the column 6.

Particularly, in the case of a member assembled into a gate shape by joining a through column and a beam on the 1st and 2nd floor, fitting the lower end 6a of the column 6 to the column base support 8 took more time because the member was large.

[Purpose of the invention]

An object of the present invention is to provide a column base support that allows easy installation of columns in the construction of houses and the like.

[Disclosure of the invention]

The column pedestal support of the present invention includes a column pedestal support main body having an outer peripheral shape that fits into the lower end of a hollow column, and an inclined guide protrusion extending inwardly and upwardly from the outer peripheral edge of the upper surface, and a column pedestal support main body that is attached to a building. A fixing part for fixing to the structure is provided.

According to the configuration of the present invention, when the lower end of the column is joined to the column base support, the inclined guide protrusion extending inwardly and upwardly from the outer periphery of the upper surface of the column base support body serves to guide the column's lower end. Even if the center of the pillar is slightly shifted from the center of the pillar base support, singing can be performed. Therefore, the fitting operation can be easily performed.

Embodiment: A first embodiment of the invention will be described based on FIGS. 1 and 2. This column base support is hollow (16 bottom 0
An inclined guide protrusion 4 extending inwardly and upwardly from the outer peripheral edge 3C of the upper surface on the column base support main body 3 having an outer peripheral shape that joins the i16a,
A fixing portion 9 for fixing the column base support main body 3 to the building structure 1 is provided.

As shown in FIG. 1, the column base support body 3 has an upwardly open box shape, and a hole for inserting the anchor bolt 2 is provided in the bottom portion 3b as a fixing portion 9. One side of the rising portion 3a is cut out to make it easier to tighten the napft 5.

The inclined guide protrusion 4 is located at the outer peripheral edge 3c of the upper surface of the column base support main body 3.
It extends inwards and upwards in a pyramidal shape, and the top is located at the center of the plane of the pedestal support main body 3, as shown in FIG.

Further, since the inclined guide protrusion 4 is not provided on the outer peripheral edge 3c of the upper surface of the notched side of the rising portion 3a, the nut 5 can be easily tightened. Although the column base support main body 3 and the inclined guide protrusion 4 are formed by bending steel materials, they may be formed by assembling separate steel materials by welding.

Duck: We will explain how to attach the column 6 using this column base support.

A column base support body 3 is inserted into an anchor bolt 2 embedded in a building structure 1 made of a cloth foundation, and fixed with a nut 5. After this, the lower end 6 of the column 6. , I to the column base support. Note that, if necessary, a threaded hole is provided in the column 6, and a bolt (not shown) is screwed in from the outside to tighten the column base support.

Note that this structure can be applied not only to cloth foundations but also to cases in which columns such as beams are installed on top of the building structure 1.

According to this configuration, when installing the column 6, the inclined guide protrusion 4 extending inward and upward from the upper outer peripheral edge 3C of the column base support main body 3 serves to guide the lower end 6a4 of the column 6. The fitting operation can be performed even if the center position of the two is slightly shifted.

Therefore, the lower end 6a of the pillar 6 can be easily fitted.

A second embodiment of the invention will be described based on FIGS. 3 and 4. This example differs from the first embodiment in that the inclined guide protrusion 10 provided on the column pedestal support body 3 does not extend to the center of the plane of the column pedestal support body 3, but ends halfway, and the fourth
As shown in the figure, the column pedestal support main body 3 is shaped such that an opening is also provided on the top surface thereof.

According to this configuration, the nut 5 can be tightened from above, so the nut 5 can be tightened more easily than in the first embodiment. The configuration and effects other than this are the same as those of the first embodiment, so their description will be omitted.

A third embodiment of the invention will be described based on FIGS. 5 and 6. In this example, an inclined guide protrusion 1o extending inwardly and upwardly is provided on the outer edge 13C of the upper surface of the rising portion of the column pedestal support main body 13 having a groove-shaped cross section.

With this configuration, the nut 5 can be tightened even from the top, making it easier. The configuration and effects other than this are the same as those of the first embodiment, so their description will be omitted.

A fourth embodiment of the invention will be described based on FIGS. 7 and 8. In this example, the pedestal support body 12 has a base plate 7 that extends outward from the rectangular cylindrical portion. The square tubular portion of the column base support main body 12 is the base plate 7.
It is attached by welding to the top. The inclined guide protrusion 11 extends upwardly and inwardly in a pyramidal shape from the upper outer peripheral edge 12a of the four sides of the pedestal support body 12, and its apex is located at the center of the plane of the pedestal support body 12. The base plate 7 has a fixing part 9 formed of a through hole located outside the rectangular tube part of the column base support main body 12, and is fixed to the building structure l by anchor bolts 2 and nuts 5.

According to this configuration, since the nut 5 is tightened on the outside of the rectangular tube portion of the column base support main body 12, the nut 5 can be tightened extremely simply. Other effects are the same as those of the first embodiment, so their description will be omitted.

Incidentally, in the first to fourth embodiments, the shape of the pillars 6 was all assumed to be square steel pipes, but the present invention can also be applied to the case of round steel pipes. In addition, the column base support body 3.12.13 and the inclined guide protrusion 4.10.11 may be solid and integrally molded in a block shape (or, the base plate 7 can also be integrally molded into a block). In this case, a hole through which a bolt can be inserted and tightened shall be provided at the center of the plane of the block.

〔Effect of the invention〕

According to the column pedestal support of the present invention, when installing the column, the inclined guide protrusion extending inward and upward from the outer peripheral edge of the upper surface of the column pedestal support body serves to guide the lower end of the column, so that the center of the column is This has the effect that the fitting operation can be easily performed even if the parts are misaligned.
