  Usually, in the shape steel, a projecting portion such as a fillet or a weld bead is formed at a butt portion (joint portion) between the flange material and the web material. For example, as shown in FIG. 10, the T-section steel 100 described in Patent Documents 1 and 2 has a fillet portion 110 having an arc-shaped cross section, and the radius r of the arc is 2 to 10 mm. Yes. For example, as described in Non-Patent Document 1, commercially available H-section steel has a radius r of the arc of the fillet portion of 8 mm or more.

  When such a T-shaped steel or H-shaped steel is used as a support for supporting a rectangular flat plate-like object (for example, a partition or a frame), the corners of the panel material interfere with the protrusions. Therefore, it is necessary to cut out the corners of the panel material, and the panel material cannot be directly constructed at the construction site. Alternatively, the protrusions need to be cut (finished), which causes problems such as a decrease in strength of the support and an increase in manufacturing costs.

  An object of one embodiment of the present invention is to provide a support body that does not require a step of cutting the protruding portion and can be constructed using a support object as it is at a construction site.

  Further, in the support in one aspect of the present invention, the two flange members have a length from the welded portion to one end portion of the flange member and the other flange member in the direction of a perpendicular line standing on the first surface. At least one of the lengths to the end portions may be different from each other.

  In the support in one aspect of the present invention, one of the two flange members may extend only from the weld portion to the first surface side of the web member.

  In the support in one aspect of the present invention, at least one of the two flange members may have a first opening through which a fixture for fixing the support to another object is passed.

  Moreover, the support body in 1 aspect of this invention may have the 2nd opening part which lets the said web material pass the fixing tool for fixing the said support target object to the said support body.

  The support set in one aspect of the present invention includes the set of the supports.

  The support structure in one aspect of the present invention includes the support set and a support object supported by the support.

The support object may be, for example, an object having a shape in which a portion supported by the support has a flat plate shape and a corner of the portion in contact with the support has a right angle. The shape of the side not in contact with the support (the side exposed to the external environment) is not particularly limited, and may have a protruding portion or a complicated shape such as decoration. Moreover, the support object which the support body of this invention makes object does not have large weight, such as a panel for building materials, but is a comparatively lightweight object (for example, unit mass is 30 kg / m < ² > or less). Specific examples include a frame, a guide plate, a partition plate (partition), a mirror plate, a balcony or terrace panel, and other small panels. Hereinafter, such a support object is simply referred to as a panel material for convenience of explanation.

<Support structure>
FIG. 1 is a cross-sectional view showing a configuration of a support structure 10A including a support 1A in the present embodiment. In the present embodiment, the case where the support 1A is an H-shaped steel having a H-shaped cross section perpendicular to the longitudinal direction will be described. That is, FIG. 1 is a schematic view showing a cross section of the support structure 10A when the support structure 10A is cut perpendicularly to the longitudinal direction of the support 1A. In FIG. 1, it is assumed that the support 1 </ b> A extends in a direction perpendicular to the paper surface, and the downward direction on the paper surface is the direction of gravity.

  As shown in FIG. 1, the support structure 10 </ b> A has an H-shaped support 1 </ b> A disposed between two struts (other objects) 5, and the opposing flange member 2 and flange member 3 in the support 1 </ b> A are arranged. While being fixed to the support | pillar 5 with the countersunk screw (fixing tool) 7, the panel material 6 is being fixed to the one surface of the web material 4 which connects the said flange material 2 and the flange material 3 with the countersunk screw 7. FIG. Hereinafter, in the present specification, the flange material 2 and the flange material 3 may be collectively referred to as flange materials 2 and 3.

  Although the support | pillar 5 is a square, for example, it is not limited to this, A concrete aspect will not be specifically limited if it has the fixing surface 51 which can fix the flange materials 2 and 3. FIG. For example, a part of a building (such as a building framework), an existing installation (furniture, an outdoor structure, etc.), or a part of a wall may be used as the column 5 to install the support 1A. The object may be actively prepared. Specifically, the column 5 may be a square steel pipe, wood, angle steel, or the like.

  The support 1A of the present embodiment is an H-shaped steel including the flange material 2, the flange material 3, and the web material 4, and has the following configuration. That is, the flange member 2 and the flange member 3 are positioned so that their plate surfaces face each other and their longitudinal directions are parallel to each other. The web material 4 is disposed so that the longitudinal direction is parallel to the flange material 2 and the flange material 3, and the end portion of the web material 4 and the flange materials 2 and 3 are respectively laser-welded. In other words, the support 1 </ b> A is formed by laser welding the two flange members 2 and 3 to both ends of the web member 4 so that the two flange members 2 and 3 face each other.

  Further, the web member 4 is laser-welded so that end portions thereof are located at the center portions of the flange member 2 and the flange member 3 in the H-shaped cross section of the support 1A.

  The flange members 2 and 3 and the web member 4 are metal flat plates. Examples of the metal include iron, steel (steel), stainless steel, aluminum, other metals or alloys, and the like. It can be appropriately selected based on the desired properties (corrosion resistance, strength, etc.) of the support 1A and the manufacturing cost. As described above, in this specification, the term “metal” means an alloy.

  The thickness of the flange member 2 is T2, the plate width is w2, and the length in the direction perpendicular to the plane including the directions of t2 and w2 (the direction passing through the paper surface in FIG. 1) is L2 (not shown). And Similarly, the thickness of the flange member 3 is t3, the plate width is w3, the length in the above direction is L3 (not shown), the thickness of the web member 4 is thickness t4, the plate width is w4, and the above. The length in the direction is L4 (not shown). In the present specification, the plate width of the flange material refers to the direction corresponding to the height direction of H in the cross section perpendicular to the plate surface of the web member 4 and the plate surface of the flange members 2 and 3 in the support 1A. It means length. Moreover, the board | plate width of a web material means the length of the direction equivalent to the width | variety (horizontal width) direction of H in the H-shaped cross section of 1 A of support bodies.

  The flange material 2 has a thickness t2 of 1.6 mm to 4.5 mm, a plate width w2 of 50 mm to 100 mm, and a length L2 of 300 mm to 3000 mm. The flange material 3 has a thickness t3 of 1.6 mm to 4.5 mm, a plate width w3 of 50 mm to 100 mm, and a length L3 of 300 mm to 3000 mm. The web material 4 has a thickness t4 of 1.2 mm to 3.2 mm, a plate width w4 of 41 mm to 196.8 mm, and a length L4 of 300 mm to 3000 mm.

  In the support 1A of the present embodiment, the plate width w2 of the flange member 2 and the plate width w3 of the flange member 3 are the same width. In addition, the thickness, the plate width, and the length of the flange member 2, the flange member 3, and the web member 4 may be appropriately selected according to the shape and weight of the panel member 6 as a support object. Further, the flange material 2, the flange material 3, and the web material 4 may be made of the same material or different kinds of materials.

  The panel material 6 has, for example, a flat plate shape with a plate thickness of 40 mm to 195 mm. The panel material 6 is not limited to this, and it is sufficient that the panel material 6 has at least a rectangular flat plate portion, and the portion on the flat plate is in a space surrounded by the flange material 2, the flange material 3, and the web material 4. The panel material 6 is supported by fitting.

  The flange member 2 is formed with a hole (first opening) 21 through which a flat head screw 7 for fixing the support 1 </ b> A to the column 5 is passed. In the supporting structure 10 </ b> A, the flange member 2 is fixed to the support column 5 with a flat head screw 7.

  Similarly, the flange member 3 is also formed with a hole (first opening) 31 through which a flat head screw 7 for fixing the support 1 </ b> A to the column 5 is passed. In the support structure 10 </ b> A, the flange member 3 is fixed to the support column 5 with a flat head screw 7.

  Here, the countersunk screw 7 may be used to screw the flange members 2 and 3 so as to reach the column 5. An adjusting member (not shown) may be provided between the plate surface of the flange members 2 and 3 and the fixed surface 51, and the plate surface and the fixed surface 51 of the flange members 2 and 3 are not in contact with each other. May be. When the width of the support 1 </ b> A is shorter than the distance between the two columns 5 by the adjusting member, the support 1 </ b> A can be stably installed by making up for the lacking portion.

  The support structure 10 </ b> A is configured such that the contact surface 61, which is one plate surface of the panel material 6, contacts the front plate surface 41, which is one plate surface of the web material 4, that is, the web material 4 is the panel material 6. It is arranged to support the bottom of the. The panel material 6 and the web material 4 are fixed by a countersunk screw 7. The web member 4 has a hole (second opening) 42 through which the countersunk screw 7 for fixing the panel material 6 to the support 1A is passed. Is formed.

  The flat head screw 7 is inserted into the web member 4 through the panel member 6 so as to be screwed into the hole 42. Here, holes may be formed in the panel material 6 in advance, and when the panel material 6 is applied to the support 1A, the holes can be formed by an electric drill or the like. In the case where holes are formed in the panel material 6 in advance, the panel material 6 may be arranged so that the positions of the holes and the hole portions 42 are aligned, and fixed with the countersunk screws 7.

  When the countersunk screw 7 is used as a fixture, the head of the countersunk screw 7 is easily embedded in the flange members 2 and 3. Therefore, it is possible to suppress the head of the countersunk screw 7 from interfering with the panel material 6 when the panel material 6 is installed.

  Further, by using the countersunk screw 7, the head of the screw does not protrude from the surface of the panel material 6 opposite to the contact surface 61. As a result, safety and design can be improved.

  The countersunk screw 7 is an example of a fixture, and other fixtures may be used as appropriate.

  Moreover, the structure which supports the panel material 6 only by mounting the panel material 6 on the web material 4 without fixing with the flat head screw 7 may be sufficient.

  For example, when a conventional H-shaped steel is used as the support 1A of the support structure 10A as described above, a fillet or a weld bead is formed at the joint between the flange material and the web material. It is necessary to cut out the corner of 6 or (ii) to cut the fillet or the weld bead in the support 1A. As a result, the panel material 6 could not be constructed as it was at the construction site. Alternatively, it is necessary to cut (finish) the protruding portion, which causes problems such as a decrease in strength of the support and an increase in manufacturing cost.

<Welding part shape of support 1A>
Support body 1A of the present embodiment has welded portion 8 formed by melting flange materials 2 and 3 and web material 4 at a joint portion between flange materials 2 and 3 and web material 4. FIG. 2 is a partially enlarged view of the welded portion 8 between the one flange member 2 and the web member 4 in the support 1A of the present embodiment.

  Here, a surface opposite to the front plate surface (first surface) 41 in the web material 4 is a back plate surface (second surface) 43. In this case, the laser beam is irradiated from the back plate surface 43 side of the web material 4 to form the welded portion 8. Moreover, when the web material 4 side surface in the flange material 2 is the web side plate surface 22, the shape of the welded portion 8 can be expressed as follows.

  That is, the length of the welded portion 8 protruding along the surface of the web material 4 from the web side plate surface 22 of the flange material 2 on the front plate surface 41 side is α, and the web side plate surface of the flange material 2 on the back plate surface 43 side. 22, the length of the welded portion 8 projecting along the back plate surface 43 of the web member 4 is β, and the length of the welded portion 8 projecting along the web side plate surface 22 of the flange member 2 from the front plate surface 41 side. Let γ be the thickness, and δ be the length of the welded portion 8 projecting along the web side plate surface 22 of the flange member 2 from the surface plate surface 41 side.

  In support body 1A in the present embodiment, the shape of welded portion 8 satisfies the conditions of α + γ ≦ 2 mm and β + δ ≦ 2 mm. Such a shape of the welded portion 8 can be realized by a manufacturing method of the support 1A of the present embodiment described later. In the support 1A, the shape of the welded portion formed by laser welding satisfies the conditions of α + γ ≦ 2 mm and β + δ ≦ 2 mm as it is without performing processing such as cutting.

  That is, in the support 1 </ b> A of the present embodiment, the length of the protruding portion in the welded portion 8 is small. Therefore, the corner portion of the panel material 6 does not interfere with the protruding portion of the welded portion 8. As a result, the panel material 6 is formed in a space surrounded by the flange materials 2, 3 and the web material 4 without processing the corners of the panel material 6 and without cutting the protruding portion of the welded portion 8. 6 can be fitted.

  Therefore, it is possible to provide a support body that does not require a step of cutting the protruding portion and can be constructed using the support object as it is at the construction site. Thereby, the manufacturing cost of 1 A of support bodies and the construction cost of 10 A of support structures can be suppressed, without reducing the intensity | strength of 1 A of support bodies.

  Further, the flange members 2 and 3 and the web member 4 constituting the support 1A are made of metal, and can be made excellent in durability (for example, corrosion resistance) by appropriately selecting the material. Therefore, the support 1A can be suitably used not only indoors but also outdoors, and can be excellent in aesthetics.

  On the other hand, when the support is made of a resin or the like, it can be manufactured so that the protruding amount of the joint portion is reduced. However, it tends to be deteriorated outdoors and tries to increase the strength. This can increase manufacturing costs. Furthermore, in order to manufacture a long support having a length in the longitudinal direction of 300 mm to 3000 mm, the manufacturing equipment becomes large and the manufacturing itself may be difficult.

  Moreover, as for 1 A of support bodies, it is preferable that the protrusion amount of the welding part 8 is 1 mm or less, and it is more preferable that it is 0.75 mm or less. The protruding amount of the welded portion 8 is the maximum length of the protruding welded portions indicated by α, β, γ, and δ.

  That is, in the support 1A, the lengths of the protruding welds indicated by α, β, γ, and δ are preferably 1 mm or less, and more preferably 0.75 mm or less.

<Method for producing support 1A>
The manufacturing method of the support 1A for supporting the panel material 6 is such that two metal flange members 2 and 3 are laser welded so that the two flange members 2 and 3 are opposed to both ends of the metal web material 4. The shape of the welded portion 8 between the flange materials 2 and 3 and the web material 4 satisfies the conditions of α + γ ≦ 2 mm and β + δ ≦ 2 mm.

  In general, in the laser welding method, the protruding amount of the welded portion can be relatively suppressed, but the welded portion satisfies the conditions of α + γ ≦ 2 mm and β + δ ≦ 2 mm as in the support 1A of the present embodiment. In general laser welding methods, since the strength of the welded portion is reduced, it is not assumed, and it is not easy to make such a small protrusion amount itself.

  The present inventors have made it possible to realize the support 1A and the support structure 10A as described above by repeatedly improving the laser welding equipment and examining various conditions of laser welding.

  That is, the process of joining by the above-mentioned laser welding can be performed as follows.

  Generally, the shape of the flange material can be thermally deformed by heat input during welding by laser welding. A method for correcting such thermal deformation is known, and laser welding equipment having such a flange material correcting mechanism was used. Further, as the laser welding equipment, one having a mechanism for suppressing the bending deformation of the web material when the thermal deformation of the flange material is corrected was used.

  In addition, the projecting amount of the welded portion was reduced by examining conditions such as the target position and irradiation angle of the laser beam. About this, the technique of patent document 3 can be used.

Specifically, the target position (irradiation position) X from the flange material on the surface of the web material is expressed as “X = Tw · tan θ” (Tw: plate thickness of the web material, θ: laser incident angle with respect to the flange material). Define. Here, the upper limit value of the target position X is “2.5 × (D / 2)” in consideration of the laser beam diameter D and the melting width (variation depending on conditions: about 1.1 to 2.5 times). It becomes. From this, the range of the irradiation angle θ is obtained as “0 <θ ≦ tan ⁻¹ ((2.5 × D / 2)) / Tw”.

  By finely adjusting the target position X and the irradiation angle θ within the above range, it is possible to perform laser welding so that the weld has desired strength characteristics and the protruding amount of the weld becomes small. Become.

  As described above, according to the manufacturing method of support 1A of the present embodiment, support 1A can be manufactured in which the shape of welded portion 8 satisfies the conditions of α + γ ≦ 2 mm and β + δ ≦ 2 mm. Therefore, it is not necessary to cut the welded portion of the support 1A. Then, at the construction site, the manufactured support 1A can be fixed to the support column 5, and the panel material 6 can be fitted as it is without processing the corners to form the support structure 10A.
