Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a handrail anchor fixing jig for erecting a handrail support.

Prior Art When installing a new handrail after removing an existing handrail, it is desirable to erect supports without damaging the existing parapet.

For this purpose, it is conceivable to fix the handrail anchor 8 using the remaining part 11 after the removal of the existing column and attach the column to this as shown in FIG. If it is not fixed, the pillar cannot be erected accurately.

However, it is extremely difficult to adjust the fixing position of the anchor and weld it while supporting it.

Purpose of the invention This invention was made to solve the above-mentioned problems.It is possible to accurately adjust the fixing position of the handrail anchor, and it can also be easily supported for welding work. The purpose is to provide a jig for use.

Structure of the invention The handrail anchor fixing jig according to this invention is
It is formed into a U-shaped cross section by a board and parallel side plates at both ends of the board, one side plate is provided with a holding part that can move forward and backward on the opposite side plate, and the board is bored approximately in the center. a base having a hole, a long hole drilled on both sides of the hole, a height adjustment bolt screwed through and a level, and a clamper holding a handrail anchor by a clamper divided into two parts; A holding part consisting of a fixing plate provided at the lower end of the clamper division body and having a long hole bored orthogonally to the long hole is placed on the base plate of the base, and The above object is achieved by making adjustment possible with a bolt passing through the elongated hole.

Embodiments Hereinafter, this invention will be explained in detail based on embodiments shown in the figures.

In the figure, A is a handrail anchor fixing jig according to this invention, which consists of a base part B and a holding part C. The base B is formed into a U-shaped cross section by the substrate 1 and parallel side plates 2, 2 at both ends of the substrate 1. The distance between the side plates 2, 2 is formed to be sufficiently larger than the width of the parapet.

One side plate 2 is provided with a presser portion 3 that can move forward and backward on the opposing side plate 2 side. That is, a bolt hole 3' is bored in the side plate 2, and bolts 3b, 3b are screwed through the bolt hole 3'.
A presser plate 3a is attached to the tip of b. Further, the holding portion 3 may be constructed only of the bolts 3b, 3b.

A rectangular hole 4 is bored approximately in the center of the substrate 1 . Elongated holes 5, 5 are bored on both sides of the hole 4, respectively. In the embodiment, the elongated holes 5, 5 are formed long in the direction perpendicular to the side plates 2, 2, but they may be formed long in parallel to the side plates 2, 2.

Nuts 5a, 5a are housed in cases 5', 5', respectively, and are slidably but non-rotatably attached to the back surfaces of the elongated holes 5, 5.

Bolt holes 6' are formed in the vicinity of the four corners of the substrate 1, and a plurality of height adjustment bolts 6 are screwed through the holes 6'.

Further, the substrate 1 is provided with a spirit level 7 having air bubbles in the liquid.

The holding part C is formed by a rectangular cylindrical clamper 13 that grips and fixes the handrail anchor 8, and this clamper 13 is divided into two clamper segments 14, 14.
The clamper divided body 14 includes a half-square cylindrical divided body 14a, flanges 14b formed on both sides of the divided body 14a, and a fixing plate 14c formed at the lower end of the divided body 14a. has been done. A long hole 15 is bored in the fixing plate 14c. In the embodiment, the elongated holes 5, 5 of the substrate 1
is formed long in the direction perpendicular to the side plate 2, so that the long hole 15 of the fixing plate 14c is formed in the split body main body 14a.
It is formed long in the direction. The divided bodies 14, 14 configured as described above are attached to the flanges 14b, 14b.
and pass the bolt 16a through the nut 16.
b is screwed together to form the clamper 13.

The long hole 1 of the fixing plate 14c of this holding part C
5 through the long hole 5 of the board 1,
It is screwed into nuts 5a, 5a.

The installation work of the handrail anchor 8 using the handrail anchor fixing jig A configured as above will be explained.

Cut the existing handrail near the top of parapet 9 of the column and remove it. 11 is the remaining part of the pillar.

A cylindrical steel rod 12 is inserted into this remaining portion 11 and projected above the upper surface of the parapet 9.

A steel rod 12 is placed in the hole 4, and the base B of the handrail anchor fixing jig A is placed on the parapet 9, and its side plates 2 are straddled between the indoor and outdoor areas.

First, the height of the base B is adjusted in accordance with the water string D stretched along the parapet 9. That is, the height of the substrate 1 is adjusted by rotating the height adjustment bolt 6, and at the same time, the substrate 1 is adjusted horizontally using the spirit level 7.

Next, rotate the bolts 3b, 3b and press the holding plate 3a.
Press against the side of the parapet 9 to fix the base B.

A handrail anchor 8 held by a rectangular cylindrical clamper 13 of a holding part C is fixed onto the hole 4. The clamper 13 is divided into two parts 14, 1.
4, the clamper divided body 14 includes a half-width cylindrical divided body 14a;
It is composed of flanges 14b, 14b formed on both sides of the main body 14a, and a fixing plate 14c formed at the lower end of the main body 14a. A long hole 15 is bored in the fixing plate 14c. In the embodiment, since the long holes 5, 5 of the substrate 1 are formed long in the direction perpendicular to the side plate 2, the long holes 15 of the fixing plate 14c are formed long in the direction of the divided body main body 14a. The divided bodies 14, 14 configured as described above are attached to the flange 14.
b, 14b are aligned, the bolt 16a is passed through, and the nut 16b is screwed together to separate the divided body main bodies 14a, 1.
Install the handrail anchor 8 inside 4a.

As described above, the holding part C, which is the clamper 13 that grips the handrail anchor 8, is fixed on the base B. The long holes 5, 5 of the substrate 1 are made to correspond to the long holes 15 of the fixing plate 14c, and bolts 5b, 5b are screwed into nuts 5a, 5a to fix them. Since the elongated holes 5 and 15 are long in directions perpendicular to each other, the fixing position of the handrail anchor 8 in the width direction and the longitudinal direction of the parapet 9 can be adjusted.

Further, when fixing the handrail anchor 8 held by the holding part C to the base B whose height and horizontal adjustment have been made in advance, the handrail anchor 8 is automatically supported vertically and the handrail anchor 8 is fixed to the holding part C. The height of the handrail anchor 8 is automatically determined by determining how far it should protrude from the clamper 13 of C.

As described above, the connecting steel 17 is interposed between the positioned handrail anchor 8 and the steel rod 12 and welded.

Thereafter, the jig A consisting of the base B and the holding part C is removed and the column is fixed to the handrail anchor 8.

Effects of the invention This invention has the above configuration and can obtain the following effects.

I○ The base B has a height adjustment bolt, level, and long hole, and the holding part C holds the handrail anchor.
Handrail anchor positioning and position adjustment can be performed extremely easily.

B○ The handrail mounting anchor can be attached to the clamper of the holding part, making it extremely easy to weld the handrail anchor.

C○ Even if the top surface of the parapet is sloped, the base board can be easily adjusted using height adjustment bolts, and the parapet can be easily mounted regardless of the slope of the top surface.
