Description

[Detailed Description of the Invention] (Industrial field of application) This invention is a column angle setting table that can be used when building columns such as columns and pillars of a building structure on a foundation in a straight or inclined manner. Regarding

(Prior Art) When building a building structure, for example, pillars, as shown in FIG. 7, an earthbuilder builds a foundation 1 according to a design drawing or the like and buries anchor bolts 2 in this foundation, Base plate 4 of pillars 3 on the completed foundation 1
The method of burying the foundation 1 and the base plate 4 with a cement mixture or the like is widely adopted after placing them, and fastening the buried anchor bolts 2 with the nuts 2a to build the pillars 3 on the foundation 1. There is.

(Problems to be solved by the invention) However, in the above-mentioned conventional pillar-shaped building structure, since the base plate 4 is placed on the foundation 1, when the flatness of the foundation surface 1 is poor, the base plate 4 is distorted. There is a problem that it is difficult to build the pillars 3 vertically with respect to the foundation 1 when there is unevenness or when there is variation in the construction work.

Further, depending on the building structure, the structure itself may be inclined and constructed. In such a structure, it is necessary to incline the pillars, but the above-described conventional pillar building structure cannot cope with this.

(Means for Solving the Problem) As a result of earnest research to solve the above-mentioned problems, the present inventor has installed a spherical or conical base between the foundation and the pillar base plate, and The present invention has been completed, paying attention to the fact that the angle of the pillars with respect to the foundation can be freely set by changing the contact position with the foundation or the pillars base plate.

That is, the pillars angle setting table according to the present invention is disposed between the upper surface of the foundation and the lower end surface of the pillars, and the pillars angle setting table for setting the pillars at an arbitrary angle with respect to the foundation, The angle setting base consists of an upper half and a lower half that are integrated with each other.
The upper surface of the upper half portion is formed into a substantially spherical shape having a radius of curvature R that is 1/2 or more of the outer diameter dimension D or a substantially conical surface with a depression angle α of 15 ° or less, while the bottom portion of the lower half portion is at least the surface. Is made of a weldable material so that it can be welded to the lower end surface of the columns, and at least one working end surface for welding and handling is formed on the lower half side portion.

In the angle setting table, the upper half part and the lower half part may be integrally manufactured from the beginning, or the upper half part and the lower half part may be separately formed and fixed to each other.

The material of the angle setting table may be any material such as a cement mixture or a metallic material such as iron, and the upper half and the lower half may be formed of the same material or different materials. Since it is important to be able to weld the angle setting base to the column base plate by reversing it, it is possible to make the entire lower half part with a material that can be welded, for example, iron, etc. The material may be formed such that its surface, in particular at least the bottom surface, is coated with a weldable material.

The work surface of the lower half part is for ensuring the handleability of the angle setting table, but at the same time, it serves as a welding point when welding the angle setting table and the pillar base plate. Therefore, this working end face may be provided on the entire circumference of the side face of the lower half part, or may be provided on a part of the side part.

Next, the reason for measuring conditions such as dimensions in the present invention will be described.

The radius of curvature R is the outer diameter dimension D on the upper surface of the upper half of the angle setting table.
1/2 or more of the substantially spherical shape, or the depression angle α is set to a substantially conical surface shape of 15 ° or less, the radius of curvature R is less than D / 2, or the depression angle α is more than 15 °. This is because, in the conical surface shape, the pillars are greatly inclined even if the contact position with the pillars is slightly changed, which makes the construction work of the pillars complicated.

Further, when the upper surface of the upper half portion is formed in a substantially conical surface shape, it is desirable that the depression angle α be 5 ° or less so that the same inclination angle setting function as in the case of the substantially spherical shape is exhibited.

If the total height H of the angle setting table exceeds 300 mm, not only will the pillars become unstable when they are built, but they will also be bulky at construction sites that require a large amount of handling. Since it becomes very complicated, it is desirable to set it to 300 mm or less.

(Operation) When building pillars, place an angle setting table on the upper surface of the foundation,
Place the pillars on it, or weld the angle setting lower half side of the pillars to the bottom end surface of the pillars with the working end surface, and place the base plate of the pillars on the upper surface of the foundation to set the angle. The position of the pillars with respect to the foundation may be set to a desired angle by appropriately adjusting the contact position between the upper surface of the upper half of the base and the upper surface of the foundation or the bottom surface of the pillars. Is set.

In addition, since the angle setting table is formed separately from the foundation, the foundation setting work and the pillar construction work are not complicated, and the height of the angle setting table is substantially constant.
The height of the pillars will not be uneven.

Further, since the working end face is formed on the lower half side portion of the angle setting table, the angle setting table is very easy to handle.

Further, since the lower half of the angle setting table can be welded, the angle setting table can be welded to the pillar side, and as a result, the construction work of the pillars, especially the centering work, is very easy.

(Example) Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 to 3 show a column angle setting table according to an embodiment of the present invention. In the figure, 10 is an angle setting table made of a weldable ferrous metal material, and the total height H of the angle setting table 10 is set to 300 mm or less, for example, 30 mm.

The angle setting table 10 is composed of an upper half 11 having a substantially spherical upper surface and a lower half 12 having a cylindrical shape. The outer diameter dimension D of the upper half 11 is 15 mm or more and 30 mm or less, for example, 44 mm. Is set,
The upper surface of the upper half portion 11 has a radius of curvature R of D / 2 or more, for example, 44 mm.
Is formed into a substantially spherical shape.

The side surface 13 of the lower half portion 12 has a height h of 1 mm or more, and the side surface 13 is a working end surface.

Further, a center mark 14 is formed at the center of the upper surface of the angle setting table 10, and positioning marks 15 are formed on the side surface 13 of the lower half portion 12 at 90 ° intervals as required.

Next, the usage method will be described. When building the pillars 3, first, as shown in FIG. 2, the pillars 3 on the upper surface of the foundation 1
Finding the position to build, put some positioning mark there, put the center mark 14 or the positioning mark 5 of the angle setting base 10 on it, and place the angle setting base 10,
The base plate 4 of the pillars 3 is placed on it, or as shown in FIG. 3, a positioning mark is placed on the bottom surface of the base plate 4, and the center mark 14 or the positioning mark 15 of the angle setting base 10 is added to it. And the bottom surface of the lower half portion 12 of the angle setting base 10 are brought into contact with each other, and the entire circumference of the side working end surface 13 of the lower half portion 12 or a part thereof and the bottom surface of the base plate 4 are welded together. The base plate 4 of 3 is placed on the base 1 in alignment with the positioning marks on the upper surface of the base 1.

The base plate 4 of the pillars 3 thus placed is fastened by screwing the embedded anchor bolts 2 and the nuts 2a to build the pillars 3 on the foundation 1. Further, for example, the left and right nuts 2a are appropriately rotated to form the pillars 3 It may be adjusted straight or at a predetermined angle.

In the pillar angle setting table of the present embodiment as described above, the spherical angle setting table 10 is provided between the base plate 4 of the pillars 3 and the foundation 1, and the angle is obtained by appropriately turning the nut 2a. Since the contact position between the setting table 10 and the base plate 4 or the foundation 1 is changed, the angle of the pillars 3 can be arbitrarily set by a simple operation.

By the way, as another method of setting the angle of the pillars 3, a method of forming a hemispherical surface of mortar or the like on the foundation 1 to form an angle setting base portion is conceivable.
It is necessary to form the angle setting base part once the foundation 1 is substantially solidified, the work of making the base is very complicated, and the heights of the angle setting base parts are likely to be uneven, so that the pillars 3 It is difficult to make the heights even. On the other hand, in the main pillar angle setting table, since the angle setting table 10 is formed separately from the foundation 1, it suffices to place the angle setting table 10 on the foundation 1,
The work of making the foundation does not become complicated, and the angle setting table 10 can be manufactured in advance in accordance with the standard at the factory etc. As a result, the height of the angle setting table 10 is made uniform and the construction height of the pillars 3 is increased. The height can be adjusted to a predetermined height.

Further, in the main pillar angle setting table, the lower half portion 12 of the angle setting table 10 has a cylindrical shape, and the side surface thereof serves as the working end surface 13. The angle setting table 10 can be handled very easily when it is placed on the column 1 or welded to the column 3 base plate 4, and the construction work of the column 3 can be simplified.

Further, in the angle setting table of the main pillars, since the lower half portion 12 of the angle setting table 10 can be welded, the angle setting table 10 can be welded and fixed to the pillars 3 side in advance, and as a result, on the foundation 1. The center position of the pillars 3 can be aligned by a simple work of placing the pillars 3, and the construction work can be simplified.

FIG. 4 shows a second embodiment of the present invention, in which the upper surface of the upper half 11 of the angle setting table 10 is formed into a substantially conical surface with a depression angle α of 15 ° or less, for example, 5 °. In this way, the upper surface of the upper half 11 of the angle setting base 10 may be formed into a substantially conical shape.

Further, FIG. 5 shows a third embodiment of the present invention. In this embodiment, the entire angle setting base 10 is formed in a substantially spherical shape, and a part of its side is cut out to form a working end face 13. The work end face 13 is formed on the angle setting base 10 in this manner.
It may be formed on at least a part of the side portion of the lower half portion 12.

FIG. 6 shows a fourth embodiment of the present invention. In this embodiment, the lower half 12 of the angle setting base 10 is connected to the outer diameter D of the upper half 11.
The diameter is set to be larger, and thus the dimension of the lower half portion 12 of the angle setting base 10 can be set arbitrarily.

(Effects of the Invention) As described above, according to the pillars angle setting table of the present invention, the pillars angle setting base is disposed between the upper surface of the foundation and the lower surface of the pillars, and the upper half upper surface thereof and the upper surface of the foundation or the pillars.
