Description

Technology Field

[0001] The present invention relates to a gauge for irregular fillet welding used, for example, when measuring the throat thickness of irregular fillet welding in steel frame fabrication or steel frame construction. Background Technology

[0002] Conventionally, a welding gauge for measuring the throat thickness of a fillet of this type of fillet weld comprises: a gauge body disposed between the plate surface of a flange member and the plate surface of a web member that are adjacent to each other in an orthogonal manner, and having a pair of mutually orthogonal contact surfaces formed to make contact with the plate surface of the flange member and the plate surface of the web member, respectively; and a main scale body slidably disposed on the gauge body in a direction in which a bisector line extending from the intersection point of each extension line of each of the pair of contact surfaces is an vertex, wherein the throat thickness is the distance between a reference point, which is the intersection point of each extension line of each of the pair of contact surfaces, and the surface of the fillet, wherein a throat thickness scale is formed on the gauge body with the reference point as the zero scale and in the direction in which the bisector line extends, and an actual throat thickness scale on the main scale body It is known that there is a structure in which a reading indicator is formed for reading. Prior art literature

[0003] Japanese Patent Publication No. Sho 34-4635 The problem to be solved

[0004] However, in the case of the above-mentioned conventional structure, for example, as shown in FIG. 14, the welding gauge is structured such that a pair of mutually orthogonal contact surfaces (not shown) are formed on the gauge body (1) to contact the plate surface (F1) of the flange material (F) and the plate surface (W1) of the web material (W), respectively. Therefore, an opening is formed on the end surface (W2) of the web material (W) that contacts the plate surface (F1) of the flange material (F), and the actual throat thickness (α) in the so-called irregular fillet welding, in which the end surface (W2) of the web material (W) having the opening is welded orthogonally to the plate surface (F1) of the flange material (F), cannot be measured.

[0005] Accordingly, according to the “General Incorporated Association of Japan Construction Industry Standard for Steel Welding (as of July 1, 2018) Standard for Fillet Welding,” when measuring the throat thickness (α) in terms of the bevel angle (θ) and bevel depth (D), the interrelationship between the plate thickness (T) of the web member (W), the bevel angle (θ), and the bevel depth (D) is determined as shown in [Table 1] below.

[0006]

[0007] Also, for example, as shown in FIG. 14 above, the neck thickness (α) is the starting point (K) of the improvement surface (K), which is the vertex (θ0) of the improvement angle (θ) of the improvement. S A reference point (O) as a )(so-called, root) and an endpoint (K) of the improvement surface (K) E A line segment (L) that makes the angle of intersection with the plate surface (F1) of the flange member (F) passing through ) equal to the improvement angle (θ). S The perpendicular line (H) from the vertex (θ0) drawn to ) LSince it is the distance between the feet (H) of the ) as shown in FIG. 14, when the bevel angle (θ) is 60°, the bevel depth (D) is 12.0 mm when the plate thickness (T) of the web member (W) is 40 mm, and the bevel depth (D) is 5.5 mm when the plate thickness (T) of the web member (W) is 19 mm, a welding gauge (E) with a bevel angle (θ) of 60° and a bevel depth (D) of 12.0 mm is manufactured, and a throat thickness (α) with a bevel depth (D) of 5.5 mm cannot be measured using this welding gauge (E). That is, even for a bevel surface (K) with the same bevel angle (θ), if the bevel depth (D) changes from bevel depth (D)1 to bevel depth (D)2, the perpendicular line (H) passing through the apex (θ0) of the bevel angle (θ) L The position of ) is perpendicular H L1 Perpendicular H from L2 There is a positional misalignment of the difference (D2-D1) between the groove depth D1 and the groove depth D2, and because of this, a welding gauge (E) with a groove depth (D) of 12.0 mm and a groove angle (θ) of the same angle cannot measure a throat thickness (α) with a groove depth (D) of 5.5 mm. Therefore, even if the groove angle (θ) is the same angle, a dedicated welding gauge (E) must be manufactured to measure a throat thickness (α) with a different groove depth (D), and it is necessary to manufacture several types of welding gauges (E) for each groove angle (θ) and groove depth (D). Consequently, the management of welding gauges (E) becomes complicated, and there are problems such as reduced workability for measuring throat thickness or the occurrence of artificial errors in measurement. means of solving the problem

[0009] In addition, the invention described in claim 2 is characterized by having a pair of mutually orthogonal contact surfaces formed on the gauge body to contact the plate surface of the flange material and the plate surface of the web material, respectively, and each of the pair of contact surfaces is formed at a position where a bisector line with the intersection point of the extension lines of each contact surface is the vertex and a perpendicular line extending from the vertex of the improvement angle of the improvement is converging, and a throat thickness scale for a fillet is formed on the gauge body, and the throat thickness scale for the fillet is a length scale in the direction in which the perpendicular line extends, with the reference point as the vertex as the zero scale, and a reading indicator for reading the throat thickness scale for the fillet is formed on the main body, and a measuring point is provided on the rear end of the main body opposite to the measuring point to contact the surface of the fillet and to measure the actual throat thickness of the fillet. Effects of the invention

[0010] As described above, in the invention of claim 1, when measuring the throat thickness of a groove with the same groove angle, a welding gauge according to the groove angle is manufactured, and by sliding the antagonist of the welding gauge, the throat thickness of a different-shaped fillet weld with different groove depths can be measured.

[0016] And, from the definition of this throat thickness (α), the general formula for the relationship between the improvement angle (θ), improvement depth (D), and throat thickness (α) is as follows [Equation 1].

[0017] [Mathematical Formula 1]

[0018]

[0019] In this case, as shown in FIG. 6, in addition to the gauge body (1) and main body (2), a setting contact surface (3a) is formed that is freely slidably disposed on the gauge body (1) in a direction perpendicular to the plate surface (W1) of the web material (W) and has a setting point (S) for setting the improvement depth (D) by contacting the plate surface (W1) of the web material (W), and a sub-body (3) is provided for setting the improvement depth (D) of the improvement formed on the end surface (W2) of the web material (W).

Also, in this case, the auxiliary body (3) is provided so as to slide freely by means of four guide pins (3d…) of the gauge body (1) and sliding surfaces (3b·3b), and an elongated hole (3c) is formed in the auxiliary body (3), and a rotating handle (3e) is screw-attached to the female screw (1e) of the gauge body (1) through the elongated hole (3c), and the above The vertebral body (3) is provided with a freely adjustable position.

[0022] Also, in this case, as shown in FIG. 9, a pair of mutually orthogonal contact surfaces (1b·1b) are formed on the gauge body (1) so as to contact the plate surface (F1) of the flange material (F) and the plate surface (W1) of the web material (W), respectively, and the pair of contact surfaces (1b·1b) each have an extension line (F) of each contact surface (1b·1b). I ·W I The intersection point (I) of ) is the vertex (I O The bisector (B) made of ) S ) and the vertex (I) of the improvement angle (θ) of the above improvement O The above perpendicular line (H) extending from ) L Each is formed at a position where ) coincides, and a throat thickness scale (α) for a fillet (M) is formed on the gauge body (1). N ) is formed, and the throat thickness scale (α) for the fillet (M) N ) is the above vertex (I O With the reference point (O) as ) as the zero scale, the above perpendicular line (H L) becomes a length scale in the direction of extension, and a throat thickness scale (α) for the fillet (M) on the main body (2).

[0023] Since the first embodiment of this case is configured as described above, when measuring the throat thickness (α) using a welding gauge (E) with a groove angle (θ) of 60° as shown in FIGS. 6, 7, and 8, first, the anterophyte (3) is operated in sliding motion corresponding to the groove depth (D), and when the groove depth (D) is 12.0 mm, as shown in FIG. 7, the setting index (S) of the anterophyte (3) I ) Improved depth scale (D M By aligning it with the 12.0 mm scale of ), and thereby substituting the bevel angle (θ) of 60° and the bevel depth (D) of 12 mm into the general formula of [Mathematical Formula 1], the theoretical throat thickness (α) is obtained as 20.8 mm, as shown in the upper part of [Mathematical Formula 2], and the actual throat thickness (α) of the fillet (M) after welding is measured and the quality of the weld can be determined by comparing it with the theoretical throat thickness of 20.8 mm. Furthermore, when the bevel depth (D) is 5.5 mm, as shown in FIG. 8, the setting index (S) of the antagonist (3) I ) Improved depth scale (D M By aligning it with the 5.5 mm scale of the above [Equation 1], and substituting the bevel angle (θ) of 60° and the bevel depth (D) of 5.5 mm into the general formula, the theoretical throat thickness (α) is obtained as 9.5 mm, as shown in the lower part of [Equation 2]. Then, the actual throat thickness (α) of the fillet (M) after welding is measured, and the quality of the weld can be determined by comparing it with the theoretical throat thickness of 9.5 mm.

[0024] [Mathematical Formula 2]

[0025]

[0026] In addition, when measuring the throat thickness (α) of a groove with the same groove angle (θ), a welding gauge (E) is manufactured according to the groove angle (θ). In this case, a welding gauge (E) for a groove angle of 60° is manufactured, and by sliding the antagonist (3) of the welding gauge (E) to move the gauge body (1) parallel in the direction in which the plate surface (F1) of the flange material (F) extends, the throat thickness (α) of a different shaped fillet weld with different groove depths (D) can be measured. This eliminates the need to manufacture a dedicated welding gauge (E) for measuring throat thickness (α) with different groove depths (D), and eliminates the need to manufacture various types of welding gauges (E) for each groove depth (D) when the groove angle (θ) is the same. Consequently, the management of the welding gauge (E) is simplified, the workability of measuring throat thickness (α) can be improved, and artificial errors in measurement can be prevented. There is a way to accurately determine the quality of irregular fillet welds by incorporating control tolerances.

[0027] Also, in this case, as shown in FIG. 9, a pair of mutually orthogonal contact surfaces (1b·1b) are formed on the gauge body (1) so as to contact the plate surface (F1) of the flange material (F) and the plate surface (W1) of the web material (W), respectively, and the pair of contact surfaces (1b·1b) each have an extension line (F) of each contact surface (1b·1b).

N Reading indicator (R) for reading ) I A) is formed, and a measuring point (Q) is provided at the rear end opposite to the measuring point (P) of the main body (2) to measure the actual throat thickness (α) of the fillet (M) in contact with the surface (M1) of the fillet (M). Therefore, the throat thickness (α) of the fillet weld that is not improved by the measuring point (Q) can also be measured, thereby increasing the flexibility of use.

[0033] Since the second embodiment of this case is configured as above, when measuring the throat thickness (α) using a welding gauge (E) with a groove angle (θ) of 50° as shown in FIGS. 10, 11, and 12, first, the anterophyte (3) is operated in sliding motion corresponding to the groove depth (D), and when the groove depth (D) is 13.5 mm, as shown in FIG. 11, the setting index (S) of the anterophyte (3) I ) Improved depth scale (D M By aligning it with the 13.5 mm scale of ), and thereby substituting the bevel angle (θ) of 50° and the bevel depth (D) of 13.5 mm into the general formula of [Mathematical Formula 1], the theoretical throat thickness (α) is obtained as 20.7 mm as shown at the top of [Mathematical Formula 3], and the actual throat thickness (α) of the fillet (M) after welding is measured, and the quality of the weld can be determined by comparing it with the theoretical throat thickness of 20.7 mm.

[0035]

[0036] However, when measuring the throat thickness (α) of a groove with the same groove angle (θ), a welding gauge (E) is manufactured according to the groove angle (θ). In this case, a welding gauge (E) for a groove angle of 50° is manufactured. By sliding the antagonist (3) of the welding gauge (E) to move the gauge body (1) parallel in the direction in which the plate surface (F1) of the flange material (F) extends, the throat thickness (α) of a different fillet weld with different groove depths (D) can be measured. This eliminates the need to manufacture a dedicated welding gauge (E) for measuring throat thicknesses (α) with different groove depths (D). Consequently, when the groove angle (θ) is the same, there is no need to manufacture various types of welding gauges (E) for each groove depth (D). As a result, the management of the welding gauge (E) is simplified, the workability of measuring throat thickness (α) can be improved, and artificial errors in measurement can be prevented. It is possible to accurately determine the quality of irregular fillet welds by incorporating control tolerances.

[0037] Also, in this case, as shown in FIG. 13, a pair of mutually orthogonal contact surfaces (1b·1b) are formed on the gauge body (1) so as to contact the plate surface (F1) of the flange material (F) and the plate surface (W1) of the web material (W), respectively, and the pair of contact surfaces (1b·1b) each have an extension line (F) of each contact surface (1b·1b). I ·W I The intersection point (I) of ) is the vertex (I O The bisector (B) made of ) S )(45°) and the vertex (I) of the improvement angle (θ) of the above improvement O The above perpendicular line (H) extending from ) L Each is formed at a position where ) coincides, and a throat thickness scale (α) for a fillet (M) is formed on the gauge body (1). N ) is formed, and the throat thickness scale (α) for the fillet (M) N ) is the above vertex (I O With the reference point (O) as ) as the zero scale, the above perpendicular line (H L) becomes a length scale in the direction of extension, and a throat thickness scale (α) for the fillet (M) on the main body (2). N Reading indicator (R) for reading ) I Since the measuring point (P) is formed and the measuring point (Q) is provided at the rear end opposite to the measuring point (P) of the main body (2) to contact the surface (M1) of the fillet (M) and to measure the actual throat thickness (α) of the fillet (M), the throat thickness (α) of the fillet weld that is not improved by the measuring point (Q) can also be measured, thereby increasing the flexibility of use.

[0038] In addition, the present invention is not limited to the above-mentioned embodiments, and the structure or shape of the gauge body (1), main body (2), and auxiliary body (3) may be appropriately modified and designed according to the flange material (F) and web material (W) and improvement angle (θ).
