Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure for a profile, and more particularly, to a joint structure for an extruded or drawn profile made of, for example, aluminum or another metal material or plastic.

[0002]

2. Description of the Related Art Generally, in order to obtain a wide plate from an extruded profile of a metal material such as aluminum, extrusion is performed by a large extruder, and a plate formed by bending and extruding by an extruder is formed by rewinding the plate. A plurality of extruded sections can be
G (Tungsten Inert Gas Arc)
Welding and MIG (Metal Inert Gas Ar
c) Means of forming a sheet material by welding or the like are known.

However, in the above-mentioned means, in the case of using a large extruder, the production equipment becomes large and the capital investment cost increases, and the wall thickness increases as the width of the plate material increases. In the case of bending, the cost increases, the work of rewinding the extruded shape in a bent state is troublesome, and it is not possible to expect a high flatness in the obtained plate.In the case of welding, the welded part and its There is a problem that the appearance of the plate material is impaired due to the high frequency of occurrence of distortion and protrusions in the vicinity, and that the material of the shape material is limited to those suitable for welding.

Therefore, as a means for solving the above problem, it is conceivable to bond a plurality of extruded members with an adhesive and join them. In this case, in order to widen the bonding area and firmly adhere, a convex ridge is provided on the end face of the joint of the profiles, and these ridges are engaged with each other, and an adhesive is interposed between the engaging portions of the two profiles. It is possible to adhere.

[0005]

However, in order to maximize the adhesive force of the adhesive and effectively bond the adhesive, it is necessary to form an adhesive gap having an appropriate interval between the meshing portions. Therefore, the shape and position of the ridges provided on the end faces of the joints of the shaped members are required to have considerably high precision and accuracy in the manufacturing stage, and are manufactured in order to manufacture such highly accurate shaped materials. However, there has been a problem that the labor and cost of the method increase. Further, even if a high-precision shaped member is manufactured, there is a problem that skill is required for the bonding operation to form the adhesive gap, and the bonding operation is troublesome.

The present invention has been made in view of the above circumstances, and an adhesive gap having an appropriate interval is easily formed by forming a correcting convex portion at a joint portion of one of the shaped members to be joined. It is an object of the present invention to provide a joint structure of shaped members that can reduce the labor of the joining operation, and that can form a flat, beautiful-looking, and higher-strength plate material.

[0007]

In order to achieve the above object, the present invention is configured as follows.

According to the first aspect of the present invention, a joint having at least two ridges is formed at an end of the profile on the joint side.
This is a joint structure of a profile in which the joints of the two profiles to be joined are meshed with each other and an adhesive is interposed between the meshing portions of the two profiles, and the ridge of the both profiles is an adhesive gap. The straightening is performed by moving the convex portion of the joint portion of the other profile toward the convex portion of the one profile so as to form the adhesive gap. And a projection for use. In this case, it is preferable to form an adhesive pool on the end face side of the ridge that is continuous with the adhesive gap at the joint of the profile members (claim 2).

[0009] Further, the correcting convex portion may be one which moves the convex ridge of the other profile toward the convex ridge of one profile so as to form the adhesive gap having an appropriate interval. The shape may be arbitrary, but it is preferable to form a straight or arcuate inclined surface for moving the ridge of the above-mentioned profile (claim 3). In this case, a straight or arc-shaped inclined surface for moving the ridge of the shape member may be formed on both sides of the correcting convex portion (claim 4).

According to the first aspect of the present invention, the ridge provided at the joint of the other profile is moved by the correcting ridge provided at the joint of the other profile, and is moved. By forming an adhesive gap having an appropriate interval between the ridge and the ridge provided on one of the profiles, the ridges can be firmly adhered to each other, and the joint can be prevented from being shifted. Further, the bonding operation can be easily performed. In this case, since the excess adhesive is absorbed by the adhesive pool by forming the adhesive pool on the end face side of the ridge connected to the formed adhesive gap, the adhesive having a more uniform and appropriate spacing is provided. A gap can be formed (claim 2).

A straight or arc-shaped inclined surface is formed on the correcting convex portion, and the convex portion of the profile is moved by the inclined surface to correct the convex portion deformed by extrusion molding or the like. This makes it possible to relatively easily form an adhesive gap having a proper interval (claims 3 and 4).

[0012]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

First Embodiment FIG. 1 is a schematic perspective view showing an example of a profile according to a first embodiment of the present invention. FIG. 2 is an enlarged sectional view (a) and an enlarged sectional view of a portion A in FIG. (B), FIG. 3 is an enlarged sectional view of a main part (a) showing a joint structure of the profile members in the first embodiment, and FIG.
It is a part enlarged view (b).

The profile 1 is formed into a hollow rectangular shape by, for example, an extruded profile made of an aluminum alloy. A joining portion 2a is formed at a lower end of the profile 1 and a joining portion 2a is formed at an upper end thereof.
b is formed. The joining portion 2a includes at least two (three in the drawing) ridges 3 projecting from the lower end surface of the profile 1 and the profile 1 between the ridges 3.
And a correction projection 4 having a substantially arc-shaped cross section projecting from the lower end face of the correction member. In this case, a concave groove 3a for accumulating the adhesive is provided on the lower end surface of the ridge 3. Further, an arc-shaped inclined surface 4a is formed on both sides of the correcting convex portion 4 (see FIG. 2A).

The joining portion 2b is provided between the positioning ridges 5 projecting vertically upward from both ends in the short direction of the upper end face of the profile 1 and an appropriate distance between the positioning ridges 5. (Four in the drawing) projecting ridges 6A
To 6D. In this case, a notch 7 is provided at the upper end of the positioning ridge 5 on the opposite surface side, and the positioning ridge 5 and the ridge 6A or the ridge 6D, and the ridge 6B and the ridge 6C. Thus, a fitting recess 8 is formed (see FIG. 2B).

The ridges 6A to 6D are fitted into the fitting recesses 8
Is slightly inclined upward so as to widen the opening portion, and a bulge having an inclined surface which is in contact with the inclined surface 4a of the correcting convex portion 4 is provided at the upper end on the side opposite to the fitting recess 8. Part 6
a to 6d are provided.

Next, the joining of the profiles 1 configured as described above will be described with reference to FIG. First, the joint 2a of at least one of the sections 1 to be joined to each other
For example, an epoxy resin-based adhesive is applied to the surface of the ridges 3 or the surfaces of the alignment ridges 5 and the ridges 6A to 6D of the joint 2b. Then, the joint 2 of the two shaped members 1 to be joined
When a and 2b are engaged with each other, 3
Each of the ridges 3 is inserted into the fitting recess 8 of the other profile 1, and an adhesive gap is formed between the ridge 3 and the ridges 6A to 6D and the alignment ridge 5. 10 are formed.

When the ridges 3 are inserted into the insertion recesses 8, the ridges 6A to 6D are provided with bulges 6a to 6d provided at upper ends thereof.
Contact with the inclined surface 4a of the correcting convex portion 4, the convex lines 6C and 6D move toward the convex line 3, that is, are corrected substantially in parallel with the convex line 3, and the uniform and proper spacing is obtained. An adhesive gap 10 having a thickness of, for example, 0.05 to 0.15 mm is formed (see FIG. 3B). In addition, in the case of a general adhesive, the adhesive strength increases as the adhesive gap 10 decreases. Therefore, if an adhesive is interposed, the interval between the adhesive gaps 10 may be 0.05 mm or less.

In addition, a dimensional error occurs during the production of the two sections 1 to be joined. Most of the dimensional error is caused by the ridge 6 in particular.
When the thickness of A to 6D is small, it is related to the angle α between the ridges 6A to 6D and the base of the joint 2b.
Errors such as 6D and the thickness of the positioning ridge 5 are generally small. For this reason, even if a dimensional error occurs at the time of manufacturing the profile 1, a major error, that is, the ridges 6A to 6D and the joint 2b
Of the angle α with the base is corrected by the inclined surface 4a of the correcting projection 4 at the time of joining the shaped members 1 as described above, so that the interval between the bonding gaps 10 is sufficient to obtain a sufficient bonding strength. It can be suppressed within the range of the appropriate interval.

At this time, an adhesive reservoir 3b is formed in a region surrounded by the adhesive reservoir concave groove 3a provided on the ridge 3 and the bottom of the fitting recess 8, and the alignment ridge 5 is further formed. An adhesive pool 7a is formed in a region surrounded by the provided notch 7 and the vicinity of the base of the ridge 3. Further, the ridges 6A-6
D and the inclined surface 4a of the convex part 4 for correction and the joint part 2a
An adhesive pool 9 is formed in a region surrounded by the base.

The shape of the inclined surface 4a of the correcting convex portion 4 is as described above, as long as the slight inclination of the ridges 6A to 6D can be surely corrected to form the adhesive gap 10 having uniform and appropriate intervals. The shape is not limited to a simple arc shape, and may be, for example, a straight shape. Further, the end face of the positioning ridge 5 and the joint 2a
As shown in FIG. 3 (a), the base may be in contact with the bases at both ends in the short direction, as long as an appropriate adhesive gap 10 is formed. Good. When a slight gap is formed, an adhesive may be interposed in this gap.

In order to more effectively and firmly bond the profiles with the above-mentioned adhesive, it is preferred that at least the surface of the region to which the adhesive is applied is subjected to a base treatment. In the case of the aluminum alloy material, the base treatment in this case includes, for example, degreasing, etching, and anodic oxide film treatment (alumite treatment) performed after the etching treatment, such as sulfuric alumite, phosphate alumite, and chemical conversion treatment. Since the adhesive strength depends on the anchor effect of the surface subjected to the base treatment, it is preferable to use an alumite treatment capable of forming innumerable holes having a large diameter on the metal surface so that the adhesive can easily enter. Further, in the alumite treatment, in consideration of the durability of the bonded joint portion, a sulfate alumite treatment capable of forming a thicker film than in the case of the phosphate alumite treatment is preferable. It is also possible to use a resin-coated material after the alumite treatment.

Second Embodiment Next, a second embodiment of the present invention will be described. FIG.
FIG. 5 is a schematic perspective view showing an example of a profile in the second embodiment of the present invention, and FIG. 5 is an enlarged sectional view (a) of a main part showing a state before joining of the profiles in the second embodiment, and a joining state. It is a principal part expanded sectional view (b).

The second embodiment is a case in which the inclined surfaces of the two correction projections are formed straight and on only one side, and two projections are bonded. In this case, the profile 11 to be joined is
For example, it is formed in a hollow rectangular shape by an extruded shape member made of an aluminum alloy, and has a joining portion 12a formed at a lower end thereof and a joining portion 12b formed at an upper end thereof.

As shown in FIG. 5A, the joint 12a
Is formed of two protruding ridges 13 protruding downward from the vicinity of both ends in the short direction of the lower end surface of the shape member 11. 13a are formed. Note that the ridge 13 is a double-shaped member 1
It is formed so as to be slightly inclined inward so that the combination of the two can be easily performed. The joining portion 12b includes a positioning ridge 14 projecting vertically upward from both ends of the upper end surface of the profile 11 in the short direction, and two projections projecting at an appropriate interval from the upper end surface of the profile 11. And the convex portion 15 for correction. In this case, the alignment projection 14 has a notch 14a formed inside the upper end portion, and the correction projection 15 has a straight inclined surface 15a whose outer surface expands from the distal end to the proximal end. Formed.

Next, the joining structure of the formed members 11 will be described with reference to FIG. An epoxy resin adhesive, for example, is applied to the surface of the ridge 13 or the alignment ridge 14 of at least one of the profiles 11, and the joints 12a and 12b are fitted (engaged) with each other. At this time, the two ridges 13 formed on the lower surface side of the profile 11
Is inserted between the positioning ridges 14 formed on the upper surface side of another shaped member 11 to be joined with the shaped member 11, so that the bulging portion 13 a of the ridge 13 and the inclination of the correcting convex portion 15 are inclined. Since the surfaces 15a come into contact with each other and the slight inclination of the ridge 13 is corrected to be substantially parallel to the alignment ridge 14, the adhesive having a uniform and appropriate interval between the ridge 13 and the alignment ridge 14 is provided. A gap 17 is formed.

In this case, also in the second embodiment, as in the first embodiment, a dimensional error occurs during the manufacturing of the profile 11. However, even if a dimensional error occurs, most of the error is related to the angle α between the ridge 13 of the joint 12a and the base of the joint 12a. It is corrected by the inclined surface 15 a of the projection 15. Therefore, the interval between the adhesive gaps 17 can be suppressed within a range of an appropriate interval (for example, 0.05 to 0.15 mm) for obtaining a sufficient adhesive strength.

On the upper end side of the adhesive gap 17, an adhesive pool 14b is formed in a region surrounded by the notch 14a of the positioning ridge 14 and the base side of the ridge 13. An adhesive reservoir 16 is formed in a region surrounded by the tip of the ridge 13 and the base of the ridge 15 for correction and the ridge 14 for positioning. As a result, the excess adhesive is absorbed by the adhesive reservoirs 14b and 16, so that the adhesive gap 17 at a more appropriate interval can be formed, and the excess adhesive can be prevented from leaking to the surface of the shape member 11. Aesthetic appearance can be improved.

The shape of the inclined surface 15a of the correcting projection 15 is such that if the slight inclination of the ridge 13 can be surely corrected to form the adhesive gap 17 with uniform and proper spacing, the straightness as described above is obtained. It does not need to be in a shape, and may be, for example, an arc-shaped inclined surface.

Third Embodiment Next, a third embodiment of the present invention will be described. FIG.

In the third embodiment, there are provided ridges 22 projecting from both ends in the short direction at the end of one of the shaped members 21 to be joined, and a fitting recess 23 formed by these ridges 22. At the end of the other shaped member 21, a fitting convex portion 28 fitted (engaged) with the fitting concave portion 23 and a correction convex portion 24 provided on both sides of the fitting convex portion 28 are provided. This is the case when it is formed.

In this case, the profile 21 in the third embodiment is used.
As shown in FIG. 6 (a), a ridge 22 having an inclined surface 22a which is inclined at an end so as to descend outward is provided at both ends in the short direction on one end surface. The projections 22 are slightly inclined, and fitting recesses 23 are formed between the ridges 22. In addition, the other end of the profile 21 forms a fitting projection 28 that can be fitted (engaged) into the fitting recess 23, and a boundary with the fitting projection 28 on the side surface of the profile 21. Is formed with a straightening surface 24a having a straight inclined surface 24a inclined inward in a direction opposite to the fitting projecting portion 28, and a base of the correcting projecting portion 24 and the fitting projecting portion 28 is formed. An adhesive pool recess 25 is formed with the side surface. Further, adhesive recesses 26 are formed in the vicinity of the front end surface on both sides of the fitting projection 28.

When the profiles 21 formed as described above are engaged with each other, first, for example, an epoxy resin-based adhesive is applied to the surface of the fitting recess 23 or the fitting projection 28 of at least one of the profiles 21. Then, the fitting projection 28 is fitted (engaged) into the fitting recess 23. At this time, the inclined surface 22a formed at the tip of the ridge 22 on one of the profiles 21
By contacting the inclined surface 24a of the correction convex portion 24 in 1, the slightly inclined ridge 22 moves inward and is corrected. As a result, an adhesive gap 27 having a uniform and appropriate interval is formed between the ridge 22 and the side of the fitting projection 28, and the adhesive reservoir recess 25 or 2 is formed.
Adhesive pool 25a, 2 in a space surrounded by
6a is formed. In this case, the gap between the bottom surface of the fitting recess 23 and the bottom surface of the fitting projection 28 is slightly wide, and is not bonded by the adhesive.

It should be noted that the shape of the inclined surface 24a of the correcting convex portion 24 is such that if the slight inclination of the convex ridge 22 can be surely corrected and the adhesive gap 27 having a uniform and appropriate interval can be formed, the straight line as described above can be formed. It does not need to be in a shape, and may be, for example, an arc-shaped inclined surface.

Further, the joint structure of the profile according to the third embodiment is not necessarily limited to the above-described configuration.
For example, as shown in FIG. 7 (a), the fitting projection 28 in the profile 21 </ b> A having the same shape as the profile 21 is fitted into the fitting recess 23.
When fitted (engaged) with the fitting, the fitting projection 28 and the fitting recess 2
3, a notch 30 having a protruding piece 29 may be formed in the vicinity of the front end surface on both sides of the fitting projection 28. By forming in this manner, the surface area of the adhesive gap 27 increases, so that the adhesive can be more firmly bonded. The notch 30 and the ridge 22
The adhesive reservoirs 30a and 30 are located in a space surrounded by
b is formed, and the excess adhesive is supplied to the adhesive pools 30a, 30
7B (see FIG. 7B), it is possible to form the adhesive gaps 27 at more uniform and appropriate intervals.

(Not shown) with an adhesive or the like, and used as a standing signboard. In this case, the projection 3 of the joint 2a is exposed at the lower end of the display panel 42, and the movable projection 6 of the joint 2b is exposed at the lower end of the display panel 42. It is preferable that the upper frame 43 is attached to the upper end and the lower frame 44 is attached to the lower end for blindfolding.

As described above, by applying the joint structure of the profile members according to the first to third embodiments of the present invention to the display body, for example, the display surface member 42 of the vertical signboard 40, the strength and flatness can be improved. In addition, since the display surface material 42 having a smooth surface and a beautiful appearance can be obtained, the strength and durability of the standing sign 40 can be improved, and the image of the user of the standing sign 40, such as a company, can be improved.

Since the joining structure of the display panel 42 is the same as that of any of the first to third embodiments, the description is omitted.

Also, a curved material having a gentle curved surface is
By joining with the joining structure of the profiles according to any of the first to third embodiments, it is possible to form an arcuate roof used for, for example, a covered pedestrian bridge or a closed elevated shelter. An example of such an arcuate roof will be described with reference to FIG. Here, a case where the shape of the joints formed at both ends of the curved shape material is the same as the shape of the joints 2a and 2b of the shape material 1 in the first embodiment will be described.

In the above, each embodiment of the present invention has been described with respect to the case where an extruded member made of an aluminum alloy is used. However, if other materials are suitable for bonding with an adhesive, for example, It goes without saying that an extruded or drawn member made of a metal material (for example, steel or the like) other than a plastic material or an aluminum alloy may be used. Further, the shape is not necessarily limited to the case where the shape is formed to be hollow, and may be formed solid.

[0045]

As described above, according to the joint structure of the profile of the present invention, the following excellent effects can be obtained.

According to the first aspect of the present invention, the ridge provided at the joint of the other profile is moved by the ridge for correction provided at the joint of the other profile, and this ridge is moved. By forming an adhesive gap having an appropriate distance between the ridge and the ridge provided on one of the profiles, the ridges can be firmly adhered to each other, and the joint can be prevented from being displaced, Further, the bonding operation can be easily performed.
