Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a multipurpose measuring jig used for manufacturing a single material of a steel frame product and assembling it.

[0002]

[Prior art]

 As a steel frame product used for a steel frame structure, for example, as shown in FIG. 2, there is a column structure 4 in which a plurality of beam joints 3 are projected on the outer surface of a column body 2 provided with a flange 1 at an end. After the manufacturing process and completion of the product as a product, the pillar structure 4 is measured from the axis of the pillar body 2 to the end of the beam joint 3, the horizontalness and verticalness of the joint end, and the pillar body 2. It is necessary to measure the size, twist, distortion of the weld, misalignment, and steps.

Conventionally, in the measurement of each part as described above, a scale is applied to the outer surface of the column main body 2 and the dimension up to the target point is read based on this, so that it takes time and time to perform the measurement. In addition to this, there is a problem that an error is likely to occur in the measurement, and a highly accurate measurement cannot be performed.

Therefore, an object of the present invention is to provide a measuring jig capable of easily and accurately performing various measurements on steel frame products.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention has a configuration in which a jig main body formed by using an aluminum mold material is provided with scale scales indicating the length dimension along the length direction.

[0006]

[Action]

 Fix the jig body with scale scales indicating the length along the length direction to both ends of the steel frame product with a vise or a piece, and glue the water thread stretched between the jig bodies. If it comes into contact with the end of the joint, the dimension from the axis of the column body to the end of the beam joint can be measured, and the above-mentioned dimension can be easily and accurately measured by visual inspection.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in the figure, a jig 11 for measuring a steel frame product includes a jig body 12 using an aluminum angle member, and a jig portion 12 on the outer surface of the jig body 12 at a position of a bent portion in the length direction. The jig body 12 is made of, for example, an aluminum angle member of 6 × 65 × 65, and its length may be arbitrarily selected within a range of about 200 mm to 4000 mm. The aluminum angle material is long and lightweight, and is convenient to handle.

As shown in FIG. 1 (A), the scale graduation 13 is a steel scale provided with graduations of a length dimension, and the scale graduation 13 extends over the entire length in the length direction with respect to the surface of the jig body 12. It is stuck and fixed. The scale scale 13 may be formed directly on the jig body 12.

An example of a steel frame product that is measured using the measuring jig 11 is a pillar structure 4 as illustrated in FIGS. 1B and 2, and as described in the section of the prior art. A flange 1 is provided at an end of a column main body 2 made of steel pipe or H-shaped steel, and a beam 3 is projected from the column main body 2.

In order to attach the jig 11 when measuring the pillar structure 4, a piece 14 and a vise 15 formed by cutting an angle member are separately prepared.

Next, a measuring method using the jig 11 will be described.

As shown in FIGS. 1B and 2, the scale graduation 13 faces upward with respect to the end face of the flange 1 provided on the column main body 2, and the upper surface of the scale graduation 13 passes through the axis of the column main body 2. The jig 11 is horizontally placed on the flange 1, and the jig 11 is fixed to the flange 1 using the piece 14 and the vise 15.

Further, a jig 11 is vertically stacked on the outer surface of the flange 1, and the jig 11 is arranged so that the surface on which the scale graduations 13 are provided passes through the axis of the column main body 2. 15 is used to fix the jig 11 to the flange 14 and the horizontal jig 11.

Further, similarly to the case of the flange 1, a horizontal jig 11 and a vertical jig 11 are fixedly arranged at the other end of the column main body 2.

Next, a water line 14 using fishing line is stretched between the facing jigs 11 and 11 and is stretched in a straight line in which the water line 14 is in contact with the end surface of the beam finishing port 3. By reading the position of the water thread 14 by the scale graduation 13, the dimension from the axis of the column main body 2 to the end face of the beam connector 3 can be visually confirmed. When a fishing line is used as the water line 14, there is no twisting and elasticity, so there is little sagging and the measurement accuracy is improved.

Further, since the water thread 14 is parallel to the line connecting the shaft centers of both ends of the column body 2, the parallelism of the end face of the beam port 3 with respect to the shaft center of the column body 2, the twist of the column body 2, etc. It can be measured by the thread 14.

Further, as shown in FIG. 2, if the jig 11 is fixed to the side surface of the beam port 3, it is possible to know the size of the water thread 14 up to the end face of the beam port 3. It is possible to calculate the actual length when the mouth 3 is short.

The use of the jig 11 is not limited to the measurement of the pillar structure 4 as shown in the drawing, but can be performed during the assembly of various structures using steel frames or the measurement of products. .

[Effect of device]

 As described above, according to the present invention, since the steel scale is provided in the length direction of the jig body using the aluminum mold material, if the steel frame product is attached and the water thread is stretched, the dimensions and twist of each part of the steel frame product are Distortions can be visually checked, and since the jig body is made of aluminum, it is lightweight and easy to handle. Therefore, various kinds of steel frame products can be easily and efficiently measured with high accuracy.
