The present invention relates to a support for supporting an object to be supported, a support set comprising a set of supports, and a support structure.

Conventionally, shaped steels, such as H-shaped steels, formed into various cross-sectional shapes depending on the application are known. In general, various shaped steels are manufactured by hot rolling using a universal rolling mill, or by welding a flange material and a web material.

When such T-shaped steel or H-shaped steel is used as a support for supporting a rectangular flat object (for example, a partition, a frame, etc.), the corner of the panel material interferes with the above-mentioned projection. Therefore, it is necessary to cut the corner portion of the panel material, and the panel material can not be applied as it is at the construction site. Alternatively, it is necessary to scrape (finish) the above-mentioned protrusion, which causes problems such as a reduction in the strength of the support and an increase in the manufacturing cost.

The two flange members are formed by welding so as to face each other, and the shape of the weld between the flange member and the web member satisfies the conditions of α + γ ≦ 2 mm and β + δ ≦ 2 mm. (Here, one plate surface of the web material is referred to as a first surface, and the back surface of the first surface is referred to as a second surface,

A method of manufacturing a support according to an aspect of the present invention is a method of manufacturing a support for supporting an object to be supported, wherein two metal flanges are provided at both ends of the metal web. A step of joining by laser welding so that two flange members face each other is included, and the shape of the welded portion between the flange member and the web member satisfies the conditions of α + γ ≦ 2 mm and β + δ ≦ 2 mm.

In this embodiment, a method for installing a panel material as an example of a supported object using a support in one embodiment of the present invention will be described.

The support target object of the support of the present invention is not necessarily limited thereto. The support target may be, for example, an object having a shape in which the portion supported by the support is flat and the corners of the portion in contact with the support are at right angles. The shape of the side (the side exposed to the external environment) not in contact with the support is not particularly limited, and may have a projecting portion or a complicated shape such as decoration. Moreover, the support target object which the support body of this invention makes object does not have big weights, such as a building material panel, but is a comparatively lightweight (for example, unit weight is 30 kg / m < ² > or less) object. Specifically, for example, a frame, a guide plate, a partition plate (partition), a mirror plate, a panel for a balcony or a terrace, other small panels, and the like can be mentioned. Such a support target is hereinafter 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 in which the support 1A is an H-shaped steel whose cross section perpendicular to the longitudinal direction is an H-shape 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, the support 1A extends in a direction perpendicular to the paper surface, and the downward direction on the paper surface is the gravity direction.

As shown in FIG. 1, in the support structure 10A, an H-shaped support 1A is disposed between two columns (other objects) 5, and the

opposing flange members

2 and 3 in the support 1A are Each is fixed to the support 5 by a countersunk screw (fixer) 7. In the support structure 10A, a panel member 6 is fixed to one surface of the web member 4 connecting the flange member 2 and the flange member 3 by a flathead screw 7. Hereinafter, in the present specification, the flange member 2 and the flange member 3 may be collectively referred to as

flange members

2 and 3.

The support 5 is, for example, a rectangular bar, but is not limited to this, and the specific embodiment is not particularly limited as long as it has the fixing surface 51 capable of fixing the

flange members

2 and 3. For example, a part of a structure (frame of a building, etc.), an existing installation (furniture, an outdoor structure, etc.), or a part of a wall may be used as the support 5 to install the support 1A. It may be an object actively prepared for Specifically, the support 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 provided with the flange member 2, the flange member 3 and the web member 4 and has the following configuration. That is, the flange member 2 and the flange member 3 are positioned such that the plate surfaces face each other and the 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 respectively, and the end of the web material 4 and the

flange materials

2 and 3 are respectively laser welded. In other words, the support 1A is formed by laser welding two

flange members

2 and 3 so that the two

flange members

2 and 3 face each other at both ends of the web member 4.

In addition, the web material 4 is laser-welded so that the end is positioned at the center of the flange 2 and the flange 3 in the H-shaped cross section of the support 1A.

The

flange members

2 and 3 and the web member 4 are flat plates made of metal, and the metal may be, for example, iron, steel (steel), stainless steel, aluminum, other metal or alloy, or 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 noted above, as used herein, the term "metal" is meant to include alloys.

The plate thickness of the flange member 2 is T2 and 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 sheet in FIG. 1) is L2 (not shown) I assume. Similarly, the plate thickness of the flange member 3 is thickness t3, the plate width is w3, the length in the above direction is L3 (not shown), the plate thickness of the web 4 is thickness t4, the plate width is w4, and The length of the direction is L4 (not shown). In the present specification, the plate width of the flange material is the height of the H shape in the cross section (the cross section of the H shape) perpendicular to the plate surface of the web material 4 and the

flange materials

2 and 3 in the support 1A. It means the length of the direction corresponding to the vertical direction. Further, the plate width of the web material means the length in the direction corresponding to the H-shaped width (lateral width) direction in the H-shaped cross section of the support 1A.

As a specific example, the flange member 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 member 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 board 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 have the same width. The thickness, plate width, and 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 the object to be supported. Moreover, the flange material 2, the flange material 3, and the web material 4 may be the same material as each other, or may be different materials from each other.

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

The flange member 2 is formed with a hole (first opening) 21 through which a countersunk screw 7 for fixing the support 1A to the support 5 is inserted. In the support structure 10 A, the flange member 2 is fixed to the support 5 by a countersunk screw 7.

Similarly, the flange member 3 is also formed with a hole (first opening) 31 through which a countersunk screw 7 for fixing the support 1A to the support 5 is inserted. In the support structure 10 A, the flange member 3 is fixed to the support 5 by a countersunk screw 7.

Here, it may be screwed so as to reach the support 5 from the

flange members

2 and 3 using the countersunk screw 7. An adjustment member (not shown) may be provided between the plate surfaces of the

flange members

2 and 3 and the fixing surface 51, and the plate surfaces of the

flange members

2 and 3 and the fixing surface 51 are not in contact with each other. May be By using the adjusting member, even when the width of the support 1A is shorter than the distance between the two columns 5, it is possible to compensate for the shortage and stably install the support 1A.

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

The countersunk screw 7 is inserted into the web member 4 through the panel member 6 so as to be screwed into the hole 42. Here, a hole may be formed in advance in the panel member 6, or when the panel member 6 is applied to the support 1A, the hole may be opened by an electric drill or the like. When a hole is formed in the panel member 6 in advance, the panel member 6 may be disposed so that the position of the hole and the hole 42 may be aligned, and may be fixed by the countersunk screw 7.

When the countersunk screw 7 is used as a fixing tool, the head of the countersunk screw 7 can be easily embedded in the

flange members

2 and 3. Therefore, when installing the panel material 6, interference of the head of the flat screw 7 with the panel material 6 can be suppressed.

Moreover, by using the flathead screw 7, the head of the screw does not protrude on the surface of the panel material 6 on the opposite side to the contact surface 61. As a result, safety and design can be enhanced.

The countersunk screw 7 is an example of a fixing tool, and other fixing tools may be used as appropriate.

In addition, the panel material 6 may be supported only by placing the panel material 6 on the web material 4 without fixing the flat plate screw 7.

In the case of using, for example, a conventional H-shaped steel 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 member and the web member. It is necessary to cut out the corners of 6 or (ii) cut the fillet or weld bead in the support 1A. As a result, at the construction site, the panel material 6 could not be constructed as it is. Alternatively, it is necessary to scrape (finish) the above-mentioned protrusion, which causes problems such as a decrease in the strength of the support and an increase in the manufacturing cost.

<Welded part shape of support 1A>
The welded portion shape of the support 1A of the present embodiment will be described below.

The support 1 A of the present embodiment has a welded portion 8 formed by melting the

flange members

2 and 3 and the web member 4 in the joint portion between the

flange members

2 and 3 and the web member 4. FIG. 2 is a partially enlarged view of a welded portion 8 between one of the flange members 2 and the web member 4 in the support 1A of the present embodiment.

Here, the surface on the opposite side of the front plate surface (first surface) 41 in the web material 4 is referred to as a back plate surface (second surface) 43. In this case, the laser is irradiated from the back plate surface 43 side of the web material 4 to form the welded portion 8. Moreover, when the surface by the side of the web material 4 in the flange material 2 is made into the web side plate surface 22, the shape of the welding part 8 can be represented 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 The length of the weld 8 projecting along the back plate surface 43 of the web material 4 from 22 is β, and the length of the weld 8 projecting along the web side plate surface 22 of the flange 2 from the front plate surface 41 side Let γ be a length, and let δ be the length of the weld 8 projecting along the web side plate surface 22 of the flange member 2 from the front plate surface 41 side.

In the support 1A in the present embodiment, the shape of the welding portion 8 satisfies the conditions of α + γ ≦ 2 mm and β + δ ≦ 2 mm. Such a shape of the welding portion 8 can be realized by the method of manufacturing 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 1A of the present embodiment, the length of the protruding portion in the welding portion 8 is small. Therefore, the corner portion of the panel material 6 does not interfere with the protruding portion of the welding portion 8. As a result, the panel material is formed in a space surrounded by the

flange members

2 and 3 and the web member 4 without processing the corners of the panel material 6 and without cutting the projecting portion of the welding portion 8 or the like. 6 can be fitted.

Accordingly, it is possible to provide a support that does not require the step of scraping the protruding portion and can be constructed using the support object as it is at the construction site. Thereby, the manufacturing cost of the support 1A and the construction cost of the support structure 10A can be suppressed without reducing the strength of the support 1A.

Further, the

flange members

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

On the other hand, when the support is made of resin or the like, although it is possible to manufacture so as to reduce the amount of protrusion of the joint, it is likely to cause deterioration etc. outdoors and to increase the strength. Then, the manufacturing cost may increase. 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 manufacturing itself may be difficult.

Moreover, it is preferable that the protrusion amount of the welding part 8 of the support body 1A is 1 mm or less, and it is more preferable that it is 0.75 mm or less. The amount of projection of the welding portion 8 is the maximum length of the lengths of the projecting welding portions shown by the above α, β, γ and δ.

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

<Method of Manufacturing Support 1A>
An example of the manufacturing method of the support body 1A of this embodiment is demonstrated below. In the method of manufacturing the support 1A for supporting the panel member 6, the two

flange members

2 and 3 made of metal are laser-welded so that the two

flange members

2 and 3 face the both ends of the web member 4 made of metal. The shape of the welded portion 8 between the

flange members

2 and 3 and the web member 4 satisfies the conditions of α + γ ≦ 2 mm and β + δ ≦ 2 mm.

Generally, in the laser welding method, the amount of protrusion of the weld can be relatively suppressed. However, as in the case of support 1A of the present embodiment, it is assumed that the welded portion satisfies the conditions of α + γ ≦ 2 mm and β + δ ≦ 2 mm because the strength of the welded portion is reduced by a general laser welding method. It was not easy to do with such a small amount of protrusion, nor was it easy.

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

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

Generally, the heat input at the time of welding by laser welding may thermally deform the shape of the flange material. A method for correcting such thermal deformation is known, and as a laser welding equipment, equipment having a correction mechanism of such a flange material was used. Furthermore, as the laser welding equipment, equipment that also has a mechanism for suppressing the bending deformation of the web material when correcting the thermal deformation of the flange material was used.

In addition, conditions such as the target position for irradiating the laser beam and the irradiation angle were examined to reduce the amount of protrusion of the weld. The technique described in Patent Document 3 can be used for this.

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

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 portion has desired strength characteristics and the amount of protrusion of the weld portion is reduced. Become.

As described above, according to the method of manufacturing support 1A of the present embodiment, it is possible to manufacture support 1A in which the shape of weld 8 satisfies the condition 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 is fixed to the support 5, and the panel material 6 can be fitted as it is without processing the corner portion, to form the support structure 10A.

<Modification>
(A) Although the support 1A and the support structure 10A of the present embodiment are in the use mode in which they are horizontally placed so that the direction of gravity is downward, the support and the support structure in one aspect of the present invention are Not limited to this.

Specifically, it may be a pillar of a building, a frame, a handrail of a balcony, or the like. Moreover, this is the same as in the other embodiments described later, and the support structure in one aspect of the present invention is appropriately configured such that the panel material can be horizontally placed, vertically placed, or obliquely placed. be able to.

(B) The support 1A of the present embodiment has the shape of an H-shaped steel in which the end of the web 4 is welded to the center of the

flanges

2 and 3, but the support in one aspect of the present invention The end of the web 4 may be welded at a position where it is biased to one end of the

flanges

2 and 3. That is, in the H-shaped cross-sectional shape, the position of the web material 4 may be shifted upward or downward to form an eccentric shape.

The support in one aspect of the present invention may be an I-shaped cross section.

(C) A modified example of the support structure 10A of the present embodiment will be described with reference to FIG. FIG. 3 is a cross-sectional view showing a configuration of a modification of a support structure 10A including the support 1A in the present embodiment.

As shown in FIG. 3, in this modification, the panel member 6 is fixed to the web member 4 by bolts 91 and nuts 92. Thus, the bolt 91 and the nut 92 can be used as an example of a fixing tool. A washer (not shown) may be interposed between the nut 92 and the web member 4.

It is preferable that the head of the bolt 91 be embedded in the panel material 6 so as not to protrude from the panel material 6.

Further, the fixing tool used to fix the

flange members

2 and 3 to the support 5 is not limited to the countersunk screw 7. For example, various anchor bolts may be used as an example of a fixing tool. It may be appropriately selected according to the material of the support 5.

(D) A modification of the support 1A of the present embodiment will be described with reference to (a) to (d) of FIG. (A) to (d) of FIG. 4 are cross-sectional views showing the configuration of a modification of the support 1A in the present embodiment.

The support in one aspect of the present invention may have different plate widths of the two flange members (hereinafter, a shape in which the plate widths of the two flange members are different may be referred to as different width flange shape). In other words, the two flange members have a length from the weld 8 to one end of the flange member and a length from the other end in the direction of the perpendicular line on the plate surface of the web member 4 At least one of them may be different from each other. Specifically, the following configuration may be employed.

As shown in (a) of FIG. 4, in the support 1 A 1 in one modification, the plate width of one of the flange members 3 a 1 is shorter than that of the flange member 2. Assuming that the length from the weld 8 to one end is wl and the length from the other end to ws, the flange 3a has wl> ws, and the length of wl is the flange 2 The length is the same as the length from the welded portion 8 to the end portion in the above.

Further, as shown in (b) of FIG. 4, in the support 1A2 in one modified example, the plate width of one of the flange members 3a2 is shorter than that of the flange member 2. The flange members 3a2 have equal lengths from the weld 8 to both ends.

Further, in the different-width flange-shaped support body in one aspect of the present invention, one of the two flange members is from the welded portion 8 only on the side of one plate surface of the web member 4 (for example, the front plate surface 41). It may extend. Specifically, the following configuration may be employed.

As shown in (c) of FIG. 4, in the support 1A3 in one modification, the plate width of one of the flange members 3a3 is shorter than that of the flange member 2. It extends only to the side of the plate surface. The flange 3 a 3 has a length from the weld 8 to the end equal to the length from the weld 8 to the end of the flange 2.

Further, as shown in (d) of FIG. 4, in the support 1A4 in one modification, the plate width of one of the flange members 3a4 is shorter than that of the flange member 2, and from the welded portion 8 to the web member 4 It extends only to one side of the plate surface. The flange 3 a 4 has a length from the weld 8 to the end shorter than the length from the weld 8 to the end of the flange 2.

Even in the case where such a different-width flange-shaped support is used, a support structure that supports the panel material 6 can be configured as in FIG. 1.

The configuration other than that described in the present embodiment is the same as that of the first embodiment. Further, for convenience of explanation, members having the same functions as the members shown in the drawings of the first embodiment are given the same reference numerals, and the description thereof will be omitted.

In the support structure 10A of the first embodiment, the support 1A having an H-shaped cross section is disposed between the two columns 5, and the panel material 6 is placed on the web material 4 that is bridged between the two columns 5. It was in the form to be placed. On the other hand, in the support structure 10B according to the present embodiment, the two supports 1B are provided, and the support 1B is fixed to each of the two columns 5, and the supports 1B have different widths. It differs in that it has a flange shape.

FIG. 5 is a cross-sectional view showing a configuration of a support structure 10B including the support 1B in the present embodiment.

As shown in FIG. 5, the support 1B of the present embodiment has the same shape as that described as the support 1A4 (see (d) in FIG. 4) in the fourth modification of the first embodiment, It has a J-shaped cross section.

The support 1B is a J-shaped steel provided with the flange member 2, the flange member 3b, and the web member 4b, and has the following configuration. That is, although the flange member 2, the flange member 3b, and the web member 4b are arranged in the same manner as the support 1A of the first embodiment, the flange member 3b has a shorter plate width than the flange member 2 and the web member 4b.
