Description

Technical Field

[0001] The present disclosure relates to a reinforcing structure for aluminum profiles.

Background Art

[0002] Conventionally, aluminum profiles have been used in many building materials due to the characteristics of the material itself, such as light weight and easy workability. In recent years, in large building materials that are increasing, as a means of suppressing the deflection of building materials due to strong winds and snow accumulation, methods of improving the section modulus of the profile by increasing the wall thickness or outer diameter of the aluminum profile, or inserting steel materials into the hollow interior as reinforcing members and performing reinforcement methods by bolt fastening or adhesive bonding are being carried out.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In the method of improving the section modulus of the profile, there are problems such as a decrease in designability and workability due to an increase in the size and weight of the profile. In the reinforcement method by bolt fastening or adhesive bonding, there are problems such as distortion occurring in the profile or the reinforcing member and deterioration of the joint portion due to the difference in the coefficient of thermal expansion between different materials.

[0005] The present disclosure has been made in view of the above circumstances, and provides a reinforcing structure for an aluminum profile that can suppress the influence of deformation of one of the profile and the reinforcing member on the deformation of the other due to temperature change while suppressing the size of the profile.

Means for Solving the Problems

[0006] The reinforcement structure of the aluminum profile according to one aspect of the present disclosure is formed of an aluminum material and has a hollow inside. Form The profile is provided with a reinforcing member that is disposed in the hollow in a non-bonded state with the profile and is formed of a material different from the aluminum material. The reinforcing member is disposed so as to stretch in the first direction in which a load acts on the profile. The profile is formed in an annular shape that is substantially rectangular in a cross-sectional view perpendicular to the longitudinal direction and has a first plate portion and a second plate portion that face each other in the first direction. The reinforcing member has a first reinforcing plate portion disposed along the first plate portion, a second reinforcing plate portion disposed along the second plate portion, and a wall portion that connects the first reinforcing plate portion and the second reinforcing plate portion, and is formed in a substantially H shape in a cross-sectional view perpendicular to the longitudinal direction. The first reinforcing plate portion is disposed with a gap on the inner surface of the first plate portion, and the second reinforcing plate portion is disposed with a gap on the inner surface of the second plate portion. .

Modes for Carrying Out the Invention

[0008] (First Embodiment) Hereinafter, the reinforcement structure of the aluminum profile according to the first embodiment will be described with reference to the drawings. As shown in FIG. 1, the reinforcement structure 1 of the aluminum profile according to the present embodiment includes a profile 10 and a reinforcing member 20. The reinforcement structure 1 of the aluminum profile is used for building materials such as fittings, for example.

[0009] The profile 10 is a long member that extends in a direction perpendicular to the plane of FIG. 1. The vertical direction in the plane of FIG. 1 is defined as the T1 direction (first direction), and the horizontal direction in the plane of the drawing is defined as the T2 direction (second direction).

[0010] The profile 10 is formed of an aluminum material. The profile 10 is formed in an annular shape that is substantially rectangular in a cross-sectional view perpendicular to the longitudinal direction. Inside the profile 10, a hollow portion s1 is formed. The hollow portion s1 is formed over substantially the entire length of the profile 10 in the longitudinal direction.

[0011] The profile 10 has a first plate portion 11, a second plate portion 12, a third plate portion 13, and a fourth plate portion 14.

[0012] The first plate portion 11 and the second plate portion 12 are formed in a flat plate shape. The plate surfaces of the first plate portion 11 and the second plate portion 12 face in the T1 direction. The first plate portion 11 and the second plate portion 12 are arranged to face each other in the T1 direction.

[0013] The third plate portion 13 and the fourth plate portion 14 connect the end of the first plate portion 11 and the end of the second plate portion 12. The third plate portion 13 and the fourth plate portion 14 are formed in a flat plate shape. The plate surfaces of the third plate portion 13 and the fourth plate portion 14 face in the T2 direction. The third plate portion 13 and the fourth plate portion 14 are arranged to face each other in the T2 direction.

[0014] On the inner surface of the first plate portion 11, a first rail 15 is provided substantially at the center in the T2 direction. The first rail 15 is provided over substantially the entire length of the first plate portion 11 in the longitudinal direction. The first rail 15 has a pair of first ribs (holding portions) 15a. The first ribs 15a extend from the first plate portion 11 toward the second plate portion 12 side. The pair of first ribs 15a are arranged at intervals in the T2 direction. The distance between the pair of first ribs 15a is substantially the same as the plate thickness of a reinforcing member 20 described later or slightly longer than the plate thickness of the reinforcing member 20.

[0015] On the inner surface of the second plate portion 12, a second rail 16 is provided substantially at the center in the T2 direction. The second rail 16 is provided along substantially the entire length in the longitudinal direction of the second plate portion 12. The second rail 16 is arranged to face the first rail 15 in the T1 direction. The second rail 16 has a pair of second ribs (holding portions) 16a. The second ribs 16a extend from the second plate portion 12 toward the first plate portion 11 side. The pair of second ribs 16a are arranged at intervals in the T2 direction. The distance between the pair of second ribs 16a is substantially the same as the plate thickness of the reinforcing member 20 described later or slightly longer than the plate thickness of the reinforcing member 20.

[0016] The reinforcing member 20 is arranged in the hollow s1. The reinforcing member 20 is formed in a flat plate shape. The plate surface of the reinforcing member 20 faces the T2 direction. The reinforcing member 20 is provided along substantially the entire length in the longitudinal direction of the profile 10. The shape of the reinforcing member 20 is not limited to a flat plate shape, and may be formed of a square tube or the like formed in a rectangular shape in a cross-sectional view perpendicular to the longitudinal direction, and may be configured to increase the distance between the pair of first ribs 15a and the pair of second ribs 16a and be arranged therebetween.

[0017] The reinforcing member 20 is formed of a material different from the aluminum material forming the profile 10. The reinforcing member 20 is formed of a material having higher rigidity than the aluminum material. The reinforcing member 20 is formed of, for example, CFRP (Carbon Fiber Reinforced Plastics) or steel material.

[0018] The reinforcing member 20 is in a non-bonded state with the profile 10. The reinforcing member 20 is not chemically bonded such as with an adhesive to the profile 10, nor is it mechanically fastened such as with double-sided tape or bolt fastening.

[0019] One end portion 20a of the reinforcing member 20 is held by the first rail 15 and sandwiched between the pair of first ribs 15a. The other end portion 20a of the reinforcing member 20 is held by the second rail 16 and sandwiched between the pair of second ribs 16a.

[0020] The end portion 20a of the reinforcing member 20 is in contact with the first plate portion 11 and the second plate portion 12, or is arranged with a slight gap from the first plate portion 11 and the second plate portion 12.

[0021] A load such as an external force acts on the profile 10 in the T1 direction in the use state. When the profile 10 is used such that the longitudinal direction of the profile 10 faces the width direction of the fitting in the horizontal frame or horizontal sash of the fitting, a load acts in the first direction T1 due to gravity, air pressure in the indoor and outdoor directions, etc. When the profile 10 is used such that the longitudinal direction of the profile 10 faces the vertical direction in the vertical frame or vertical sash of the fitting, a load acts in the first direction T1 due to the opening and closing of the shoji, air pressure in the indoor and outdoor directions, etc.

[0022] When a load acts in the T1 direction, the end portion 20a of the reinforcing member 20 abuts against the first plate portion 11 and the second plate portion 12 and resists in the T1 direction, thereby suppressing the deformation of the profile 10 such as the deflection of the first plate portion 11 and the second plate portion 12.

[0023] When arranging the reinforcing member 20 inside the profile 10, it is only necessary to insert it from the longitudinal end portion of the reinforcing member 20 between the pair of first ribs 15a and between the pair of second ribs 16a.

[0024] In the reinforcing structure 1 of the aluminum profile configured in this way, when a load acts on the profile 10 in the T1 direction, the reinforcing member 20 resists against the load by stretching in the T1 direction. Since the reinforcing member 20 is arranged in the hollow of the profile 10, it is not necessary to increase the profile 10 itself such as the wall thickness of the profile 10, and the size of the profile 10 can be suppressed.

[0025] In the reinforcing structure 1 of the aluminum profile, the reinforcing member 20 is formed of a material different from the aluminum material forming the profile 10, and there may be a difference in the coefficient of thermal expansion between the reinforcing member 20 and the profile 10. Since the reinforcing member 20 is not joined to the profile 10, it is suppressed that the deformation of one of the reinforcing member 20 and the profile 10 affects the deformation of the other due to temperature change.

[0026] In the reinforcement structure 1 of the aluminum profile, a pair of first ribs 15a and a pair of second ribs 16a for holding the reinforcing member 20 are provided in the hollow s1 of the profile 10. Thereby, rattling, displacement, etc. of the reinforcing member 20 are suppressed.

[0027] In the reinforcement structure 1 of the aluminum profile, the reinforcing member 20 is held by a pair of first ribs 15a and a pair of second ribs 16a provided at intervals in the T2 direction on the profile 10. Thereby, the movement of the reinforcing member 20 in the T2 direction is restricted.

[0028] (Second Embodiment) Next, the reinforcement structure of the aluminum profile according to the second embodiment will be mainly described with reference to FIG. 2. In the description of the embodiments shown below, the same members as those described above are denoted by the same reference numerals, and the description thereof will be omitted.

[0029] As shown in FIG. 2, in the reinforcement structure 1A of the aluminum profile, the reinforcing member 20 is held by a pair of attachments (holding portions) 30. The attachment 30 is disposed in the hollow s1 of the profile 10. The attachments 30 are disposed on both sides in the T2 direction with the reinforcing member 20 interposed therebetween. The pair of attachments 30 are symmetrically disposed about the center in the T2 direction.

[0030] The attachment 30 is a short member. A plurality of attachments 30 are arranged at intervals in the longitudinal direction of the profile 10.

[0031] The attachment 30 is formed in a substantially C shape in a cross-sectional view perpendicular to the longitudinal direction. The attachment 30 has a holding wall portion 31 and a bent wall portion 32.

[0032] The holding wall portion 31 is formed in a flat plate shape. The plate surface of the holding wall portion 31 faces the T2 direction. The holding wall portion 31 is arranged along the surface 20b of the reinforcing member 20 that faces the T2 direction. One end portion 31a of the holding wall portion 31 in the T2 direction does not reach the first plate portion 11. The other end portion 31a of the holding wall portion 31 in the T2 direction does not reach the second plate portion 12.

[0033] The bent wall portion 32 extends in a direction away from the surface 20b of the reinforcing member 20 from both end portions 31a of the holding wall portion 31 in the T1 direction. The end portion 32a of the bent wall portion 32 is in contact with or is arranged with a slight gap from the third plate portion 13 and the fourth plate portion 14.

[0034] The holding wall portion 31 is adhered to the reinforcing member 20 using a sponge-like double-sided tape 36. The holding wall portion 31 may be adhered to the reinforcing member 20 using an adhesive or a double-sided tape that is not sponge-like. The reinforcing member 20 is sandwiched by the attachment 30 from both sides in the T2 direction.

[0035] In the aluminum profile reinforcing structure 1A configured as described above, when a load acts on the profile 10 in the T1 direction, the reinforcing member 20 stretches in the T1 direction and resists the load. Since the reinforcing member 20 is arranged in the hollow of the profile 10, it is not necessary to increase the profile 10 itself such as the wall thickness of the profile 10, and the size of the profile 10 can be suppressed.

[0036] In the aluminum profile reinforcing structure 1A, the reinforcing member 20 is formed of a material different from the aluminum material forming the profile 10, and there may be a difference in the coefficient of thermal expansion between the reinforcing member 20 and the profile 10. Since the reinforcing member 20 is not joined to the profile 10, it is suppressed that the deformation of one of the reinforcing member 20 and the profile 10 affects the deformation of the other due to temperature change.

[0037] In the reinforcement structure 1A of the aluminum profile, the reinforcing member 20 is held by being sandwiched by the attachments 30 from both sides in the T2 direction. As a result, the movement of the reinforcing member 20 in the T2 direction is restricted. Since the attachment 30 can be a separate member from the profile 10, there is no need to use a dedicated profile.

[0038] In the reinforcement structure 1A of the aluminum profile, the attachment 30 and the reinforcing member 20 are fixed by a sponge-like double-sided tape 36. As a result, the vibration generated in the profile 10 is absorbed by the sponge-like double-sided tape 36, so that rattling noise can be suppressed.

[0039] (Third Embodiment) Next, the reinforcement structure of the aluminum profile according to the third embodiment will be mainly described with reference to FIG. 3. As shown in FIG. 3, the reinforcing member 20B is disposed in the hollow s1 so as to be self-supporting. The reinforcing member 20B is formed in a substantially rectangular shape in a cross-sectional view perpendicular to the longitudinal direction of the profile 10. The reinforcing member 20B is disposed along substantially the entire length of the profile 10 in the longitudinal direction.

[0040] The reinforcing member 20B has a first reinforcing plate portion 21, a second reinforcing plate portion 22, a third reinforcing plate portion 23, and a fourth reinforcing plate portion 24.

[0041] The first reinforcing plate portion 21 and the second reinforcing plate portion 22 are formed in a flat plate shape. The plate surfaces of the first reinforcing plate portion 21 and the second reinforcing plate portion 22 face the T1 direction. The first reinforcing plate portion 21 and the second reinforcing plate portion 22 are disposed opposite to each other in the T1 direction. The first reinforcing plate portion 21 is disposed in contact with or with a slight gap from the inner surface of the first plate portion 11. The second reinforcing plate portion 22 is disposed in contact with or with a slight gap from the inner surface of the second plate portion 12.

[0042] The third reinforcing plate portion 23 and the fourth reinforcing plate portion 24 connect the end of the first reinforcing plate portion 21 and the end of the second reinforcing plate portion 22. The third reinforcing plate portion 23 and the fourth reinforcing plate portion 24 are formed in a flat plate shape. The plate surfaces of the third reinforcing plate portion 23 and the fourth reinforcing plate portion 24 face the T2 direction. The third reinforcing plate portion 23 and the fourth reinforcing plate portion 24 are arranged to face each other in the T2 direction. The third reinforcing plate portion 23 is arranged in contact with or with a slight gap from the inner surface of the third plate portion 13. The fourth reinforcing plate portion 24 is arranged in contact with or with a slight gap from the inner surface of the fourth reinforcing plate portion 24.

[0043] When loads act on the profile 10 in the T1 direction and T2 directions, the reinforcing member 20B resists the loads by stretching in the T1 direction and T2 directions.

[0044] In the aluminum profile reinforcing structure 1B configured as described above, when a load acts on the profile 10 in the T1 direction, the reinforcing member 20B resists the load by stretching in the T1 direction. Since the reinforcing member 20B is arranged in the hollow of the profile 10, it is not necessary to increase the size of the profile 10 itself, such as the wall thickness of the profile 10, and the size of the profile 10 can be suppressed.

[0045] In the aluminum profile reinforcing structure 1B, the reinforcing member 20B is formed of a material different from the aluminum material forming the profile 10, and there may be a difference in the coefficient of thermal expansion between the reinforcing member 20B and the profile 10. Since the reinforcing member 20B is not joined to the profile 10, it is suppressed that the deformation of one of the reinforcing member 20B and the profile 10 affects the deformation of the other due to temperature changes.

[0046] In the aluminum profile reinforcing structure 1B, the reinforcing member 20B itself is self - supporting in the hollow. If the reinforcing member 20B is arranged in the hollow, the reinforcing member 20B can reinforce the profile 10, so that a simple configuration can be achieved.

[0047] The various shapes, combinations, etc. of the constituent members shown in the above - described embodiments are examples, and various changes can be made based on design requirements and the like without departing from the gist of the present disclosure.

[0048] For example, in the first embodiment, when loads act on the profile member 10 in both the T1 direction and the T2 direction, rails such as the first rail 15 may also be provided on the third plate portion 13 and the fourth plate portion 14, and the reinforcing member may be cross-shaped in a cross-sectional view perpendicular to the longitudinal direction.

[0049] In the third embodiment, the reinforcing member 20B does not have to be formed in a substantially rectangular shape in a cross-sectional view perpendicular to the longitudinal direction of the profile member 10. For example, the reinforcing member 20B may be formed in a substantially H shape in a cross-sectional view perpendicular to the longitudinal direction of the profile member 10. The reinforcing member 20B may not have the third reinforcing plate portion 23 and the fourth reinforcing plate portion 24, and may have a wall portion connecting the middle in the T2 direction of the first reinforcing plate portion 21 and the middle in the T2 direction of the second reinforcing plate portion 22. The reinforcing member 20B may be formed in a substantially triangular shape in a cross-sectional view perpendicular to the longitudinal direction of the profile member 10. A configuration may be adopted in which one side of the triangle abuts on either the first plate portion 11 or the second plate portion 12, and the vertex opposite to one side of the triangle abuts on the other of the first plate portion 11 and the second plate portion 12.
