Description

  The present invention relates to a bag.

  Conventionally, a fence has been provided above the opening of a building such as a window or an entrance to block rain and sunlight. Such a bag is required to be lightweight, to have high strength, and to be difficult to deteriorate due to changes in temperature and humidity.

In order to obtain a bag satisfying such a requirement, it is conceivable to use a sandwich panel as disclosed in Patent Document 1, for example. In addition, the sandwich panel of Patent Document 1 includes two face materials arranged so as to face each other and a core material arranged between the two face materials, and the core material and each surface. The material is joined by brazing material.
JP-A-11-347722

  Incidentally, since the brazing material of Patent Document 1 uses a binary eutectic of aluminum (Al) -silicon (Si), it is necessary to heat to about 600 ° C. during brazing. Since the melting temperature and brazing temperature of aluminum or aluminum alloy that is a material of the core material are close to each other, there is a possibility that the face material and the core material are softened during the brazing, thereby causing distortion and bending. In particular, when the upper face material is softened, a portion that is not in contact with the core material hangs down, so that a large number of dents are generated on the surface of the face material, and repair with a putty or the like is unavoidable.

  In addition, if the face material is thickened or an iron plate coated with an aluminum film on the surface as in Patent Document 1 is used as the face material, the problem that a depression is formed on the surface of the face material can be solved. However, since the weight of such a sandwich panel is increased, if this is used as a bag, a great deal of labor is required for the installation work at the construction site.

  Then, this invention makes it a subject to provide the wrinkles which a dent does not generate | occur | produce on the surface of a face material, although it is lightweight.

The present invention, which was created to solve such problems, is a gutter attached to a building, and two aluminum or aluminum alloy face materials arranged facing each other in the vertical direction, and the two sheets Each of the face materials and the core material comprises 27 to 37% by mass of copper and silicon. 5-10 mass% is included, and the remainder is joined to each other by a powdery brazing material made of aluminum and inevitable impurities.

  The form of the core material is not particularly limited. For example, a core material may be a material in which a plurality of cylindrical bodies are gathered in a honeycomb shape or a corrugated plate material.

  According to this type of brazing, the brazing material that joins each face material and the core material has a composition close to the ternary eutectic. The melting point of the material is lowered. In other words, in this kite, the brazing temperature can be set to a temperature sufficiently lower than the melting temperature of aluminum or aluminum alloy that is the material of the face material and core material. Therefore, even if the thickness of the face material is reduced, the surface of the face material is unlikely to be depressed.

  In addition, the scissors according to the present invention in which the face material and the core material are joined by brazing are subject to aging deterioration due to changes in temperature and humidity, compared to the scissors that join the face material and the core material with an adhesive. It also has the side effect of being difficult. In addition, when a baking coating that has a short drying time and excellent durability and adhesion is applied to a ridge that joins the face material and the core material with an adhesive, the adhesive is heated by the heat (about 120 to 160 ° C) due to the baking coating. However, if it is a spear according to the present invention that is joined with a brazing material, there is no fear that the brazing material will be altered even if baking coating is performed. Become.

Incidentally, the brazing material, after melting an alloy of the composition, Ru der those obtained by spraying quenched in a vacuum or in an inert gas. If the brazing material is in powder form, not only will it be easy to mix with the flux required to remove the oxide during brazing and brazing, but it will also reduce the amount of oxide in the brazing material. Therefore, the amount of flux can be reduced.

  In addition, from the viewpoint of obtaining a light wrinkle, it is preferable that the plate thickness of the face material is small. However, if the thickness is less than 0.5 mm, the strength of the wrinkle itself may be insufficient. desirable. Further, from the viewpoint of obtaining a wrinkle having no dents on the surface (that is, no need for repair), it is preferable that the plate thickness of the face material is large, but if it exceeds 2.5 mm, the weight increases. It is desirable that it is 5 mm or less.

  Moreover, when the said core material consists of an aggregate | assembly of a some cylindrical body, it is desirable that the side surfaces of the said adjacent cylindrical body are mutually joined through the said brazing material. In this way, since a plurality of cylindrical bodies are integrated, it is possible to obtain a high strength ridge.

  In the case where the core material is composed of a plurality of cylindrical bodies, each cylindrical body includes a cylindrical main body part and a support part provided on the inner peripheral side of the main body part, It is desirable that the upper and lower ends of the main body portion and the upper and lower ends of the support portion are in contact with the face materials. When the support portion of the cylindrical body is brought into contact with the face material, it is possible to surely prevent the face material from sagging in a portion not in contact with the main body portion, so that the surface of the face material becomes smooth. In addition, if a part of a rectangular plate material is bent into a cylindrical shape to form a main body part, and the remaining part of the plate material is bent to the inner peripheral side of the main body part to form a support part, the cylindrical body described above can be simplified. Can be created.

  According to the present invention, it is possible to obtain a wrinkle that is light but does not generate dents on the surface of the face material.

Here, the brazing material will be described in detail.
The brazing material contains 27 to 37% by mass of copper (Cu) and 5 to 10% by mass of silicon (Si), and the balance is made of aluminum (Al) and inevitable impurities. The brazing material may be divided into an aluminum silicon alloy (Al—Si based alloy) and copper (Cu) before heating and become an alloy having the composition described above during heating, or before brazing (brazing) It may be an alloy of the above composition from the previous).

  Examples of the brazing material that becomes an alloy having the composition described above upon heating include, for example, an aluminum or aluminum alloy in which an aluminum silicon alloy (Al-Si alloy) and copper (Cu) are used as the face material 12 (or the cylindrical body 131). There is a clad product made of rolled material.

  Examples of the brazing material having the above composition before heating include, for example, a powdered material obtained by melting an alloy having the above composition and then spraying it in a vacuum or an inert gas and quenching. The brazing material obtained by such a manufacturing method has a fine spherical shape having an average particle diameter of 10 to 100 μm, but its surface contains almost no impurities such as oxides. It becomes possible to reduce. Here, the vacuum is an atmosphere having a degree of vacuum of 200 torr or less, and the inert gas is a gas that does not oxidize the brazing material. For example, an argon-based noble gas, reduction of hydrogen, etc. Gas, non-oxidizing gas such as nitrogen.

  The powder brazing material may be used after adding pure water to make it uniformly turbid and slurrying. In addition, when a mixed slurry is formed by mixing a fluoride-based flux containing cesium fluoride (CsF) having a solid content of 11% by mass or more into the slurry, the brazing material and the flux are brought together in one step. Since it can apply to the material 12 etc., manufacture becomes easy.

  The fluoride-based flux is obtained by adding cesium fluoride to a potassium fluoride-based non-corrosive flux (commonly known as “Nocolok (registered trademark)”). The flux to which cesium fluoride is added has a lower melting point than that of the flux to which cesium fluoride is not added.

  The solid content of the fluoride-based flux may be 3 to 50 mass% with respect to the solid content of the mixed slurry. If it is such a range, it will become possible to maintain the certainty of brazing, suppressing the usage-amount of an expensive flux.

  In addition, as another form of the brazing material having the above-described composition before heating, for example, an alloy (brazing material) having the above-described composition is made of aluminum or the face material 12 (or the cylindrical body 131). The rolled material made of aluminum alloy may be clad, or of course, the rolled material may be clad with the alloy having the above composition and the flux.

The manufacturing conditions and the like shown below are that the frame 11 is formed of JIS3003 alloy, the rolled plate of JIS3003 alloy having a thickness of 1.5 mm is used as the face material 12, and the plate material of JIS3003 alloy having a thickness of 0.5 mm is used as the diameter. This is a case where a cylindrical body 131 to be the core material 13 is formed into a cylindrical shape of 25 mm.

  First, as shown in FIG. 6A, a mixed slurry formed by turbidity of a powdery brazing material and a flux is applied to one surface of the face material 12 and dried. The application method is not particularly limited, and for example, the mixed slurry may be sprayed with a spray or the like, or may be applied with a brush or the like. In addition, you may apply | coat the solution containing a flux after apply | coating the slurry formed by adding pure water to a powdery brazing material without using a mixed slurry, or after applying the solution containing a flux, The slurry may be applied.

  Next, as shown in FIG. 6B, a plurality of cylindrical bodies 131, 131,... Serving as the frame body 11 and the core material 13 are mounted on the surface of the one surface material 12 to which the brazing material is adhered. Then, the other face material 12 is placed on the frame 11 and the core material 13 with the surface to which the brazing material is attached facing down.

  Subsequently, the temporarily assembled bag body 10 is filled with nitrogen gas. Specifically, after placing a weight (not shown) on the other face member 12, the temporarily assembled bag body 10 is placed in a container, the inside of the container is evacuated, and then nitrogen gas is introduced into the container. Should be introduced. At this time, since the through-hole 131c is formed in the cylindrical body 131 serving as the core material, nitrogen is reliably introduced into the cylindrical body 131.

  Next, the temporarily assembled cocoon body 10 is put in a furnace, heated to 540 ° C. over about 40 minutes, and maintained at a temperature of 540 to 550 ° C. for about 5 minutes. Thus, the main body 10 in which the core 12 and the core material 13 are integrated with the brazing material is obtained. Since the brazing material is also sucked in between the side surfaces of the adjacent cylindrical bodies 131 and 131 (see FIG. 5A) by capillary action, the cylindrical bodies 131 and 131 are also joined to each other via the brazing material. The

A lock nut 633 is provided.

Next, an example of a procedure for attaching the fence 1 configured as described above to a building will be described.
First, as shown in FIG. 7, the attachment member 20 and the connection member 30 are fixed to the upper surface of the bag main body 10. Further, the lower end plug 63 of the suspension member R is connected to the connection member 30.

  The slope of the rod main body 10 can be adjusted by rotating the main member 61 of the suspension member R in an appropriate direction and increasing or decreasing the distance between the upper end plug 62 and the lower end plug 63. When the gradient of the scissors body 10 is determined, the locking nut 633 is moved to the main material 61 side and fastened.

  According to the scissors 1 having the above-described configuration, since the brazing material joining the face materials 12 and the core material 13 has a composition near the ternary eutectic, a binary eutectic brazing material is used. The melting point of the brazing material is lower than that of the conventional bran. In other words, in this saddle 1, the brazing temperature can be set to a temperature sufficiently lower than the melting temperature of the aluminum or aluminum alloy that is the material of the face material 12 and the core material 13, so that during brazing The face material 12 is not softened. Therefore, even when the plate thickness of the face material 12 is reduced, the surface of the face material 12 is unlikely to be depressed.

  Note that the heel 1 that joins the face material 12 and the core material 13 by brazing has aged deterioration due to changes in temperature and humidity compared to the heel 1 that joins the face material 12 and the core material 13 with an adhesive. It also has the secondary effect of being difficult to progress. Moreover, when the baking coating which has short drying time and is excellent in durability and adhesiveness is applied to the ridge which joins the face material 12 and the core material 13 with an adhesive, the heat (about 120 to 160 ° C.) due to the baking coating is applied. There is a possibility that the adhesive may change in quality, but if it is 庇 1 that is joined by a brazing material, there is no fear that the brazing material will change even if the baking coating is performed, so that it is possible to actively adopt the baking coating. .

  Moreover, since the support part 131b of each cylindrical body 131 used as the core material 13 is contact | abutted to the face material 12, it becomes possible to prevent the droop of the face material 12 reliably. That is, the surface of the face material 12 becomes smooth.
