Description

[Detailed Description of the Invention] The present invention relates to a support for a post that is disposed on an inclined foundation such as a staircase to support a post used for a handrail or the like.

(Prior Art) Posts used in prefabricated stair handrails are supported by inserting their lower ends into box-shaped supports and attaching the supports to concrete foundations. . The support used here is usually
It has a lower surface that is perpendicular to the support column so that it can be installed on a flat foundation that does not slope, so if the foundation surface is sloped, the lower surface of the support should be adjusted at the site to match the sloped foundation surface. It is necessary to match the foundation surface to the underside of the support by cutting it diagonally to fit the foundation surface, or, conversely, by chipping away at said foundation at the point where the support will stand. When such treatment is carried out, the appearance of the area is damaged, but since caulking is generally applied on the foundation, the lower part of the support is buried and there is no problem. However, this is troublesome as it adds extra work at the site, and reduces work efficiency.

(Problem to be Solved by the Invention) Therefore, it may be considered to place the lower surface of the support body at an angle in advance as a support for the column for the stair handrail. However, the angle of the slope of the stairs varies depending on the conditions at the construction site, which causes inconveniences in terms of parts management and production, such as the need to prepare many types of supports with different slopes.

(Purpose of the invention) The present invention was made based on the above circumstances, and provides a support for a column whose structure is devised so that it is compatible with the range of inclination angles of stairs that will be put into practical use. This is what I am trying to do.

(Means for Solving the Problem) Therefore, in the present invention, as will be clear from the examples described below, a box-shaped support 8 into which the pillar 3 is inserted is placed on an inclined foundation 1 such as a staircase. In the support for a column, the lower part of the column 3 used for a handrail 4 or the like is inserted and supported from the upper surface opening of the support 8. Slanted support surface 8a formed at the average inclination angle of foundation 1
The left and right sides thereof are formed into left and right side wall surfaces 8b, 8b, in which a cross pin insertion hole 12 consisting of a round hole and a mounting hole 5 are formed at one place above the middle part and one place below the middle part, respectively. The front and rear sides thereof are formed into front and rear wall surfaces 8c, 8c which are formed to widen in the front and back direction, and the width between the upper ends of the front and rear wall surfaces 8c, 8c is approximately equal to the front and rear width of the above-mentioned column 3, and the above-mentioned With the lower part of the column 3 inserted through the upper opening of the support 8, the column 3 is inserted through the insertion hole 5 formed through the column 3 so as to communicate with the cross pin insertion hole 12. It is characterized in that it is pivotally supported by a cross pin 6 so as to be freely rotatable back and forth, and its lower part is fixed by a set screw 14 screwed through the mounting hole 5.

The lower surface of the support body 8 is an inclined support surface 8a formed at an expected average inclination angle of the foundation, for example, 40 degrees, and the lower surfaces of the flanges 9, 9 are aligned with this inclined support surface 8a. Further, the support body 8 is arranged on the left side in the direction perpendicular to the direction of inclination thereof.
Cross pin insertion holes 12, 12 through which the cross pin 6 is inserted are bored in the right side wall surfaces 8b, 8b, and at a level below the cross pin insertion holes 12, 12, a required tilting allowable range, for example, front and back. The front and rear wall surfaces 8c, 8c are formed so as to be inclined downward and widen toward the front and back so that the support column 3 can be tilted within a range of 5 to 10 degrees.
Incidentally, one of the front and rear wall surfaces 8c, 8c may be formed vertically, and the other may be formed in an inclined shape. Further, the upper edges 8c', 8c' of the front and rear wall surfaces 8c, 8c end at the level of the cross pin insertion holes 12, 12, and the upper edges of the left and right side wall surfaces 8b, 8b end at the upper edge 8c'. , 8c'.

In addition, the foundation 1 has a trust tapping screw 10.
The handrail 4 includes a cap 4a, a bottom plate 4b for receiving the cap 4a, a lattice 4c extending downward from the bottom plate 4b, and a lower end of the lattice 4c. It is equipped with a rim 4d, etc., and the Kasagi bottom plate 4b and the rim 4d are attached to the support 3 via attachment fittings.

Further, in this embodiment, the cross pin insertion holes 1 are provided in the left and right side wall surfaces 8b, 8b of the support body 8.
Screw mounting holes 15, 15 into which setscrews 14 for supporting and fixing are inserted are bored below 2, 12.

In such a configuration, the support column 3 is inserted into the support body 8, and the cross pin 6 is first inserted into the cross pin insertion hole 5 via the cross pin insertion holes 12, 12, and the support column 3 is pivotally supported by the support body 8. do. In this state, the support 8 is placed on the foundation 1, and the support 8 is fixed to the foundation 1 by screwing the trust tapping screw 10 into the fissure plug 13. In this state,
The column 3 is rotated around the cross pin 6 to tilt the column 3 within the support 8 and stand up in the vertical direction.
Then, the support column 3 is inserted through the screw mounting holes 15, 15.
When a hole 16 is made with a drill or the like and a set screw 14 is screwed into the hole 16, the column 3 is fixed to the support body 8 in its upright state. As mentioned above, for the pillar 3 constructed in this way, the Kasagi bottom plate 4b, the trunk rim 4d
etc. are attached to form the handrail 4.

In addition, in the above embodiment, the cross pin 6 is connected to the support column 3.
The nut 7 is screwed on the opposite side of the pillar 3 to attach it, but by using a tapping screw as the cross pin 6 and screwing it in from both sides of the support 3, it is possible to pivot the support 8. It goes without saying that the structure may be configured so as to support it.

(Effects of the invention) As detailed above, the present invention is based on Basic 1.
The lower part of the column 3 is inserted and held via the cross pin 6 into the left and right side wall surfaces 8b, 8b of the support body 8, which is fixed by bringing the lower inclined support surface 8a into contact with the support body 8. After the column 3 is rotated in the vertical direction, the lower part thereof is fixed with the set screw 14, so there is no need to manually support the center of gravity of the column 3 while rotating the column 3 in the vertical direction. , the rotation operation work and the fixing work can be easily performed. Further, the cross pin insertion hole 12 for inserting the cross pin 6 provided on the left and right side wall surfaces 8b, 8b of the support body 8 and the mounting hole 5 for screwing the set screw 14 at the lower part thereof are both round holes, and are vertically oriented. The fixed support column 3 does not tilt due to loosening of screws, etc., and is excellent in terms of safety.
