Abstract

PROBLEM TO BE SOLVED: To provide a partition post bearing metal fixture capable of greatly reducing the execution process for mounting it to a concrete floor surface and very easily and surely bearing loading work. SOLUTION: Since an internal wall of a loading hole 7 is directly pushed with an elastic bearing section 6 by motions inserting a bearing metal fixture 1 into the loading hole 7 excavated in a concrete floor surface 2, an outside case for loading the bearing metal fixture 1 is not required as usual. By the constitution, as the execution process for mounting the outside case to the concrete floor surface 2, such the execution process, etc., as the loading hole is filled with high accelerator of hardening and fixing or mortar, etc., to fix the bearing metal fixture can be omitted.

The inventor has found that the metal fitting has a single structure that ensures the same supporting function as the conventional one, and has completed the present invention.

The present invention has been made in view of such a problem, and the construction process for mounting on a concrete floor surface is greatly reduced, the mounting work is extremely easy, and the partition can be reliably supported. It is intended to provide a column support fitting.

[0021]

In order to achieve the above-mentioned object, a partition column supporting bracket of the present invention mounts a cylinder having an upper part opening in a mounting hole of a predetermined depth excavated on a concrete floor, A partition column support fitting adapted to mount and support one end of a column from the opening, wherein the cylindrical body is formed to have a slightly smaller diameter than the mounting hole, and a part of the cylindrical body has a diameter larger than the hole diameter. It is characterized in that an elastic support portion bulging in the outer diameter direction is formed as much as possible. According to this feature, since the inner wall of the mounting hole is directly pressed by the elastic support portion by the operation of inserting the supporting metal into the mounting hole excavated on the concrete floor, the mounting of the supporting metal as in the related art is performed. This eliminates the need for the outer case, thereby eliminating the step of filling and fixing, for example, a super-hardening agent or mortar as a construction step for attaching the outer case to the concrete floor surface.

In the partition column supporting bracket of the present invention, the elastic supporting portion is formed around the lower end portion with a plurality of vertically split grooves cut in the axial direction from the lower end portion, and is divided by the vertically split grooves. It is preferable that a bulging portion bulging in the outer diameter direction is formed on the divided piece. By doing so, it is possible to form a bulging portion having elasticity at the end of one pipe by bending the plurality of divided pieces formed by the vertically dividing grooves in the outer diameter direction.

The partitioning column support fitting of the present invention is provided with a diameter increasing means in which the partitioning column support fitting is mounted on the bottom of the mounting hole and the elastic support portion expands the diameter by the action of mounting the partitioning column support fitting into the mounting hole. It is preferable if done. By doing so, the elastic support portion is expanded by the diameter-expanding means in the mounting hole only by the action of mounting the partitioning column support bracket to the mounting hole, so that the inner wall surface is added to the elastic pressing force against the wall surface of the mounting hole. Can be pressed more strongly.

[0024] In the partitioning column support fitting of the present invention, the diameter expanding means is provided with a cored bar having a tapered shape through which an opening having an upper end formed at the lower end of the elastic support portion can be inserted at the bottom of the mounting hole. Preferably, when the partitioning column support fitting is mounted in the mounting hole, the opening expands the elastic support portion by an action of inserting the core bar. By doing so, the core metal is engaged with the opening by the axial pressing operation of mounting the partitioning column support bracket in the mounting hole, and the bulging portion is evenly expanded by the tapered surface. A uniform pressing force is generated against the inner wall of the hole, so that the column support bracket can be securely fixed.

It is composed of

A counterbore 8 having a diameter slightly larger than the diameter of the flange 4 and having a depth corresponding to the thickness of the flange 4 is formed at the periphery of the opening of the mounting hole 7. When the cylindrical body 3 of the metal fitting 1 is inserted and the flange 4 is supported in the counterbore hole 8, the upper surface of the flange 4 is flush with the concrete floor surface 2.

In the figure, reference numeral 9 denotes a cap for closing the opening of the support fitting 1. The cap 9 has an outer diameter formed so as to be insertable into the cylindrical body 3 of the support fitting 1, and has a locking hole 11 on the side surface. Is formed by a cylindrical core body 10 whose lower end is cut obliquely, and a disk 12 attached to the upper end of the core body 10.

The burrs around the counterbore hole 8 are removed by rags.

Next, as shown in FIG. 3 (d), when the distal end of the cylindrical body 3 of the support fitting 1 is pressed into the mounting hole 7 in the axial direction and is elastically supported by this pressing force. The portion 6 is reduced in diameter, and the inner wall of the mounting hole 7 is inserted while being elastically pressed, so that the flange 4 of the support fitting 1 is seated in the counterbore hole 8. Finally, the opening of the support fitting 1 is closed by the cap 9, and the construction process for mounting the support fitting 1 is completed as shown in FIG.

When the plurality of support fittings 1 are sequentially mounted on the concrete floor 2 in this manner, the cap 9 is removed from the support fitting 1, and the lower ends of the poles (not shown) are inserted and supported on these support fittings 1. The poles are erected on the concrete floor surface 2, and the plurality of erected poles are provided with projections on the upper or lower side surface as in the conventional case, and a net is stretched on these engagement parts. The fence is configured.

In this case, the cap 9 removed from the support fitting 1 is locked by inserting the through hole 11 formed in the cap 9 into the locking portion of the pole.

As described above, since the inner wall of the mounting hole 7 is directly pressed by the elastic supporting portion 6 and mounted by the operation of inserting the support fitting 1 into the mounting hole 7 excavated in the concrete floor surface 2, The mounting work of the support fitting 1 is extremely easy, and an outer case for mounting the support fitting is not necessary as in the conventional case. Thus, for example, ultra-hard fixing as a construction process for mounting the outer case on a concrete floor surface It is possible to omit a step of filling and fixing an agent or mortar or the like.

Further, an elastic bulging portion can be formed at the end of one pipe by bending a plurality of divided pieces formed by the vertically dividing grooves 5 to bend in the outer diameter direction.

The partitioning column support fitting 14 according to the present embodiment includes the elastic support portion 6.
An opening is formed at the lower end of the mounting hole 7.
The distal end of the tapered portion 16 of the cored bar 15 as a diameter expanding means installed at the bottom of the inside is configured to be insertable.

The column supporting bracket 14 thus constructed
According to the above, the elastic support portion 6 is expanded by the diameter expanding means in the mounting hole 7 only by the action of mounting the support fitting 1 in the mounting hole 7, and thus the elastic pressing force against the wall surface of the mounting hole 7 is increased. The wall surface can be pressed more strongly. Furthermore, mounting holes 7
The core metal 15 is engaged with the opening at the lower end of the support fitting 1 by the axial pressing operation for mounting the support fitting 1 therein, and the bulging portion 6 is evenly expanded in diameter by the tapered surface. A uniform pressing force is generated against the inner wall of the hole, so that the column support bracket can be securely fixed.
