[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an architectural steel product mainly composed of an H-shaped steel, an I-shaped steel, etc., used for the construction of buildings and the like.
The present invention relates to a jig for a building steel product measuring instrument for measuring the total length, floor height, connection length, and the like formed on a steel frame (hereinafter referred to as “steel frame”) at the time of inspection or the like.

[0002]

2. Description of the Related Art Conventionally, steel pillars and beams used for building construction are manufactured in a single plant in a factory, and the single steel products are assembled at a building construction site by connecting the pillars and beams to form a building. I have. There are holes in steel products to connect columns and beams.

In order to control the quality of steel frame products, the length, floor height, connection length, etc. of columns and beams are measured for each part with reference to the distance between the holes. In order to measure the distance between the centers of the holes, as shown in FIG. 4, a score line 3 is formed at the center of the hole 2 formed in the H-shaped steel 1, and the length between the score lines 3 is directly read by a straight scale 6. It is conceivable to measure. However, in the case where such a ruled line 3 is used, if a rib 4 is welded between the holes 2, the rib 4 hinders direct measurement between the ruled lines 3. 3 is provided with an L-shaped insert 5, and a straight scale 6 is applied between the inserts 5 to form the hole 2.
To measure between the centers.

[0004]

In the case where the deposit 5 is used, since the measurement is performed while the deposit 5 is held down, it is not possible to accurately measure the interval between the ruled lines 3. In addition, it takes time and a person to fill the ruled line 3 in each hole 2. Also, the accuracy of the ruled line 3 varies from person to person, which has a bad influence on the quality.

Next, an embodiment of the present invention will be described with reference to the drawings.

FIGS. 1 and 2 show a first embodiment of the present invention. A steel beam 11 used for building construction or the like is provided with flange portions 13 on both sides of a web plate 12. The flange 13 has holes 14 for bolting and the like.
15 are provided. The jig body 16 inserted into each of the holes 14 and 15 is formed in a vertically long frusto-conical shape, and a top portion 17 is formed at the tip end thereof, and a taper portion 18 is formed over the entire peripheral surface. Further, the tapered portion 18 is provided with an engaging groove 20 over the entire direction of the central axis 19 of the jig body 16,
One edge 21 on the inner side of the engagement groove 20 is formed so as to coincide with the central axis 19 of the jig body 16. 22 is the jig body 16
A notch formed in a semicircular shape on the tip side of the notch, and the notch 22 and the engaging groove 20 form a projection 23. The convex part 23 is screwed with a thumbscrew 24 serving as a fixing tool. By tightening the thumbscrew 24, an L-shaped insert 25 formed to have the same width as the engaging groove 20 is fixed. In addition, 11 mm is a metal piece made of steel or the like formed in a U-shape attached to the beam 11,
A number of metal pieces 11A are attached to the beam. 26 is a beam
A hook formed on the flange portion 13 to carry 11.

Next, the operation of the above configuration will be described. First, when the jig body 16 is inserted into the hole 14 provided on one side of the beam 11 from the top 17 side, a taper portion 18 having the same diameter as the hole 14 is formed.
Are engaged and a temporary fixing state is established. Similarly the other hole 15
When another jig body 16 is inserted so as to engage from the top 17 side thereof, the portion of the tapered portion 18 having the same diameter as the hole 15 is engaged and temporarily fixed, and the center shaft 19 of the jig body 16 and each The positions of the holes 14 and 15 coincide with the center. And the pair of jig bodies
The insert 25 is inserted into each of the 16 engagement grooves 20, and the outer edge 25a of the outer side of the insert 25 is engaged with the end 21 of the engagement groove 20,
Together match the position of the central axis 19 of the end edge 25a and the jig body 16 of the Sashigane 25, the flange portion 13 of the bottom surface of the Sashigane 25
The mounting bracket 25 with each thumb screw 23.
Fix to 20.

In this state, the edge 25 of the pair of inserts 25
The length between the edges 21 of the engagement groove 20, that is, the length between the holes 14 and 15, can be accurately measured by placing a straight scale 27 between the holes a.

As described above, according to the above embodiment, the holes 14,
Center axis of jig body 16 provided with tapered portion 18 engageable with 15
The engagement grooves 20 are provided in the entire 19 direction, and the one side edge 21 on the inner side of the engagement grooves 20 is formed so as to coincide with the central axis 19 of the jig body 16, so that the holes 14, 15 are formed. After the jig main body 16 is inserted, the edge 25 of the engagement groove 20 is further engaged with the one side edge 25a on the outer side of the insert 25, and the insert 25 is simply inserted into the engagement groove 20. The length between the centers of the holes 14 and 15 can be measured. In particular, since the jig body 16 is formed in a conical shape and provided with a tapered portion 18, it is possible to cope with various diameters of the holes 14, 15 , and the engagement groove 20
It is formed over the entire length of the conical jig body 16 itself.
The one side edge 25a of the L-shaped insert 25 is
Not matching or engaging with the edge 21 of the groove 20
Alternatively, the jig body 16 is inserted into the holes 14 and 15 with the
The bottom of the insert 25 on the top of the flange 13
Hole (e.g., creating a gap)
Regardless of the diameter, when attaching the deposit 25 or the jig body 16
The displacement can be found immediately. Further, since the long piece 27 can be set while avoiding the metal piece 11A and the hook 26, the measurement can be performed without being disturbed by the metal piece 11A and the hook 26.

In addition, since the jig body 16 is temporarily fixed to the holes 14 and 15 and the measurement is performed with the insert 25 fixed to the engaging groove 20, the work of writing the ruled line is not only unnecessary. This eliminates the need to perform the measurement while holding down the insert 25 as in the conventional example, so that a highly accurate measurement operation can be performed.

FIG. 3 shows a second embodiment of the present invention.
The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

In this embodiment, a jig body 16 is inserted into a hole 14 formed in a web plate 12 of a beam 11 of a field welding type. The length between the holes 14 and 15 can be accurately measured without disturbing the ribs 28 by applying the straight scale 27 between the edges 25a of the insert 25.

The present invention is not limited to the above-described embodiment. For example, the jig body may be modified not to have a frustoconical shape but a sharp conical shape.

[0019]

According to the present invention, a conical jig main body which can be inserted into a hole formed in a building steel frame product, and which is formed over the entire length of the jig main body in the center axis direction, engages with an L-shaped insert. And an engagement groove provided so as to be capable of being provided, wherein one side edge of an inner side of the engagement groove is formed so as to coincide with a central axis of the jig body, and an inner side of the engagement groove is formed. It is designed to engage one side edge with the edge of the insert, and easily measures the length between the centers of holes even if there is an obstacle etc. in the middle of the steel frame.
And can be installed and fixed regardless of the hole diameter.
Can quickly detect misalignment when attaching the
It is possible to provide a jig for an expensive measuring instrument for building steel products.
