Description

The present invention relates to an adhesive method and an adhesive structure of a structure, and more particularly to an adhesive method and an adhesive structure of a structure using a structural adhesive.

Structural adhesives are used in a wide range of fields such as vehicles, electrical equipment, ships, construction / civil engineering, and space industry. According to JIS (Japanese Industrial Standards) K6800, "structural adhesive" is defined as "reliable adhesive that can withstand a large load for a long period of time".

For example, a room temperature curable structural adhesive is often used to attach ship fixtures. By using such a structural adhesive, even if the part to which the fixture is attached is a thin steel plate, thermal deformation such as welding strain does not occur, and it is used as one of the alternative means for welding. ..

By the way, since it takes at least 10 minutes or more for the structural adhesive to be able to hold the structure to be bonded, the worker holds it by hand or fixes the structure using a jig. It is necessary to do it.

Further, Patent Document 1 describes a method of adhesively joining members to each other by using a heat-curable structural adhesive, which is a room temperature curing type on the outside along the applied structural adhesive. It is disclosed that after applying an instant adhesive and temporarily joining the two in that state, a curing treatment is performed by heating the structural adhesive.

Japanese Unexamined Patent Publication No. 2005-350547

As described above, holding the structural adhesive until it is cured with the assistance of an operator or a jig is wasteful in working time and increases the working cost. Further, in a structure attached to an exposed portion such as a ship's fixtures (receptacle, lighting, electric wire support, equipment installation base, etc.), a certain strength is required for the adhesive portion.

In the invention described in Patent Document 1 described above, since the instant adhesive is arranged on the outside of the structural adhesive, the end portion of the structural adhesive exists at a position sandwiched between the members to be bonded. It will be. In general, structural adhesives shrink during curing and are prone to cracking at their ends. Such cracks cause a decrease in the strength of the bonded portion.

The present invention has been devised in view of such problems, and is capable of temporarily fixing the structure at the time of bonding and maintaining the strength of the bonded portion after bonding. The purpose is to provide a structure.

According to the present invention, there is a method of adhering a predetermined structure to the surface of a portion to be adhered, which is a coating area calculation step of calculating a coating area of a structural adhesive and a temporary fixing adhesive, and the structural bonding. A shape specifying step for specifying the shape of an adhesive portion having an adhesive surface having a size equal to or larger than the total area of the coating agents and the temporary fixing adhesive, and the structural adhesive and the temporary adhesive on the adhesive surface. It includes a coating step of applying a stopping adhesive and a bonding step of pressing the adhesive surface against the surface of the bonded portion to bond the adhesive, and the structural adhesive protrudes from the outer periphery of the adhesive surface in the bonding step. As described above, there is provided a method for adhering a structure, which comprises applying the structural adhesive in the coating step.

In the coating area calculation step, the coating area of the structural adhesive is calculated based on the weight of the structure, and the coating area of the temporary fixing adhesive is the weight of the support member that supports the main body of the structure. It may be a step of calculating based on.

In the shape specifying step, the adhesive portion has a main adhesive surface to which the structural adhesive is applied and an auxiliary adhesive surface to which the temporary fixing adhesive is applied, and the auxiliary adhesive is provided near the center of the adhesive surface. The step may be a step of specifying the shape of the adhesive portion so that the surface is arranged and the main adhesive surface is arranged on the outer periphery thereof.

In the shape specifying step, the adhesive portion has a main adhesive surface to which the structural adhesive is applied and an auxiliary adhesive surface to which the temporary fixing adhesive is applied, and the auxiliary adhesive surface is provided on the outer periphery of the main adhesive surface. The step may be a step of specifying the shape of the adhesive portion so as to arrange a plurality of tabs forming the above.

The coating step may include a step of linearly applying the structural adhesive so as to form a plurality of rows.

Further, according to the present invention, the structure is such that a predetermined structure is adhered to the surface of the bonded portion, and the size is equal to or larger than the total area of the structural adhesive and the temporary fixing adhesive. Provided is an adhesive structure of a structure having an adhesive surface and including an adhesive portion configured such that the structural adhesive protrudes from the outer periphery of the adhesive surface at the time of adhesion.

The coating area of the structural adhesive may be calculated based on the weight of the structure, and the coating area of the temporary fixing adhesive may be calculated based on the weight of the support member that supports the structure.

The adhesive portion has a main adhesive surface to which the structural adhesive is applied and an auxiliary adhesive surface to which the temporary fixing adhesive is applied, and a plurality of auxiliary adhesive surfaces are formed on the outer periphery of the main adhesive surface. It may have tabs.

According to the structure bonding method and bonding structure according to the present invention described above, after calculating the coating area of the structural adhesive and the temporary fixing adhesive required for bonding the structure, the structural adhesive and the temporary fixing adhesive are temporarily applied. By specifying the area of the adhesive surface to which the stopping adhesive is applied and the shape of the adhesive portion, the structural adhesive required for adhering the structure can be applied to the adhesive surface, and the structural adhesive can be applied. A temporary fixing adhesive required to hold the structure until it hardens can be applied to the adhesive surface. Therefore, the structure can be adhered to the surface of the bonded portion without the assistance of an operator or a jig, and the structure can be easily temporarily fixed at the time of adhesion.

Further, according to the present invention, the structural adhesive protrudes from the outer periphery of the adhesive surface at the time of bonding, so that even if shrinkage occurs during curing of the structural adhesive, the adhesive surface of the structure It is possible to reduce cracks that occur between the surface of the bonded portion and the surface of the bonded portion. Therefore, it is possible to suppress a decrease in the strength of the bonded portion and maintain the strength of the bonded portion after bonding.

The method of adhering the structure 1 according to the first embodiment of the present invention is a method of adhering the structure 1 to the surface of the bonded portion 2, and the coating area of the structural adhesive 3 and the temporary fixing adhesive 4. A shape that specifies the shape of the adhesive portion 11 having an adhesive surface 11a having a size equal to or larger than the total area of the coating area calculation step Step 1 and the coating areas of the structural adhesive 3 and the temporary fixing adhesive 4. The specific step Step 2, the coating step Step 3 for applying the structural adhesive 3 and the temporary fixing adhesive 4 to the adhesive surface 11a, and the bonding step Step 4 for pressing the adhesive surface 11a against the surface of the bonded portion 2 to bond them. Including, the structural adhesive 3 is applied in the coating step Step 3 so that the structural adhesive 3 protrudes from the outer periphery of the adhesive surface 11a in the bonding step Step 4.

The structure 1 is, for example, an accessory such as a receptacle, a lighting, an electric wire support, and an equipment installation stand, but is not limited thereto. Further, the bonded portion 2 is an exposed portion that forms a flat surface such as a floor surface, a wall surface, and a ceiling surface of a ship. Further, the structure 1 includes, for example, as shown in FIG. 3C, a main body portion 1a and a support member 1b that supports the main body portion 1a. Therefore, in the structure 1, after the support member 1b is fixed to the bonded portion 2, the main body portion 1a is attached to the support member 1b.

The coating area calculation step Step 1 includes a first calculation step Step 11 for calculating the coating area of the structural adhesive 3, and a second calculation step Step 12 for calculating the coating area of the temporary fixing adhesive 4. In addition, either of the first calculation step Step 11 and the second calculation step Step 12 may be processed first, or may be processed at the same time.

The structural adhesive 3 is, for example, a second-generation acrylic structural adhesive suitable for adhering metals, but the structural adhesive 3 is appropriately selected depending on the materials of the structure 1 and the bonded portion 2. Can be done. When the structure 1 is a ship's fixture, the structural adhesive 3 is preferably a room temperature curable type.

Since the structural adhesive 3 is a member that holds the structure 1 (main body 1a and support member 1b) after curing, it needs to have at least strength that can hold the weight of the structure 1. Therefore, the coating area of the structural adhesive 3 is calculated based on the weight of the structure 1 (main body portion 1a and support member 1b). When the support member 1b is sufficiently lighter than the main body 1a, the coating area of the structural adhesive 3 may be calculated based on the weight of the main body 1a.

The temporary fixing adhesive 4 is, for example, an instant adhesive containing cyanoacrylate as a main component, but is not limited thereto. Further, depending on the weight and material of the support member 1b, the temporary fixing adhesive 4 may be a double-sided tape.

The temporary fixing adhesive 4 only needs to have a strength capable of holding the support member 1b until the structural adhesive 3 is cured, and does not need to have a strength high enough to hold the main body portion 1a. Therefore, the coating area of the temporary fixing adhesive 4 is calculated based on the weight of the support member 1b.

The shape specifying step Step 2 is a step of specifying the shape of the adhesive portion 11 of the structure 1, that is, the adhesive portion 11 of the support member 1b in the present embodiment. The adhesive portion 11 has a flat plate shape that can be adhered to the adhered portion 2 forming a flat surface. The outer shape of the adhesive portion 11 is, for example, a quadrangular shape having an R shape at the corner portion, as shown in FIG. 2 (A), but is not limited thereto. The adhesive portion 11 may have an outer shape such as a circular shape, an elliptical shape, or a polygonal shape.

In the shape specifying step Step 2, for example, as shown in FIG. 2A, the adhesive portion 11 applies the structural adhesive 3 to the main adhesive surface 113 and the temporary fixing adhesive 4 to the auxiliary adhesive surface 114. This is a step of specifying the shape of the adhesive portion 11 so that the auxiliary adhesive surface 114 is arranged near the central portion of the adhesive surface 11a and the main adhesive surface 113 is arranged on the outer periphery thereof.

The area of the main adhesive surface 113 is specified to be larger than the coating area of the structural adhesive 3 calculated by the first calculation step Step 11 of the coating area calculation step Step1. Further, the auxiliary adhesive surface 114 is specified to have a size equal to or larger than the coating area of the temporary fixing adhesive 4 calculated by the second calculation step Step 12 of the coating area calculation step Step 1.

In this way, in the shape specifying step Step 2, after specifying the outer shape of the adhesive portion 11, the adhesive is bonded based on the coated areas of the structural adhesive 3 and the temporary fixing adhesive 4 calculated in the coating area calculation step Step 1. The final shape of the portion 11 is specified.

The coating step Step 3 includes a first coating step Step 31 for applying the structural adhesive 3 to the main adhesive surface 113, and a second coating step Step 32 for applying the temporary fixing adhesive 4 to the auxiliary adhesive surface 114. .. For convenience of explanation, in FIG. 2B, the structural adhesive 3 is shown in dark gray, and the temporary fixing adhesive 4 is shown in light gray.

In the coating step Step 3, for example, as shown in FIG. 2B, the structural adhesive 3 and the temporary fixing adhesive 4 are applied. The order of the first coating step Step 31 and the second coating step Step 32 is not limited to the order shown in FIG. 1, and the second coating step Step 32 may be processed first.

Further, as shown in FIG. 2B, the structural adhesive 3 and the temporary fixing adhesive 4 are applied in a linearly piled state so as to form a plurality of rows. By applying the structural adhesives 3 in a straight line at predetermined intervals in this way, not only can the structural adhesives 3 be evenly distributed over the main adhesive surface 113 at the time of bonding, but also the air during spreading Can be suppressed from being mixed. If air is mixed into the structural adhesive 3, the adhesive strength is lowered, so it is preferable to suppress the mixing of air.

Further, it is preferable that the structural adhesive 3 applied to both sides of the portion where the temporary fixing adhesive 4 is applied in a straight line is arranged on substantially the same straight line as the temporary fixing adhesive 4. With such an arrangement, the temporary fixing adhesive 4 can be sealed without leaking to the outside when the structural adhesive 3 is spread.

Further, the structural adhesive 3 applied to the peripheral edge of the adhesive surface 11a is applied in an amount that can protrude from the outer periphery of the adhesive surface 11a when the adhesive portion 11 is pressed against the adhesive portion 2. For example, in the structural adhesive 3 shown in FIG. 2B, it is defined as the first to fifth rows in order from the left.

The amount of the structural adhesive 3 in the first row is adjusted so as to protrude on the left side and the upper and lower sides of the figure of the adhesive surface 11a by spreading during adhesion. The amount of the structural adhesive 3 in the second row to the fourth row is adjusted so as to extend on both the upper and lower sides of the figure of the adhesive surface 11a by spreading at the time of adhesion. The amount of the structural adhesive 3 in the fifth row is adjusted so as to protrude on the right side and the upper and lower sides of the figure of the adhesive surface 11a by spreading at the time of adhesion.

In the bonding step Step 4, as shown in FIG. 2 (B), the adhesive portion 11 is pressed against the surface of the bonded portion 2 to spread the applied structural adhesive 3 and temporary fixing adhesive 4. This is a step in which the structural adhesive 3 is evenly distributed on the main adhesive surface 113 and is held in a state of protruding from the outer periphery of the adhesive surface 11a. At this time, since the temporary fixing adhesive 4 is evenly distributed on the auxiliary adhesive surface 114, the structure 1 (support member 1b) is shown in FIG. 2B without the assistance of a worker or a jig. It can be held in the indicated state.

Before the structural adhesive 3 is cured, as shown in FIG. 3A, the structural adhesive 3 is in a state of being raised from the peripheral edge of the adhesive portion 11 (a state of being convex outward). After that, when the structural adhesive 3 hardens with the passage of time, the structural adhesive 3 shrinks, and as shown in FIG. 3B, the portion protruding from the peripheral edge of the adhesive portion 11 is recessed (a state in which the portion protruding from the peripheral edge portion 11 is recessed. It will be transformed into an inwardly convex state).

In this way, by shrinking the structural adhesive 3 at the portion protruding from the peripheral edge portion of the adhesive portion 11, cracks generated between the adhesive surface 11a and the surface of the adhesive portion 2 can be suppressed. Therefore, it is possible to suppress a decrease in the strength of the bonded portion 11 and maintain the strength of the bonded portion 11 after bonding.

After the structural adhesive 3 is cured, the main body 1a is attached to the support member 1b as shown in FIG. 3C. The configurations of the main body 1a and the support member 1b shown are merely examples, and are not limited to the configurations shown.

According to the method for adhering the structure 1 according to the first embodiment described above, the adhesive surface 11a has a size equal to or larger than the total area of the coating areas of the structural adhesive 3 and the temporary fixing adhesive 4. The adhesive structure of the structure 1 including the adhesive portion 11 configured so that the structural adhesive 3 protrudes from the outer periphery of the adhesive surface 11a at the time of adhesion is formed.

Next, a modified example of the coating step Step 3 will be described with reference to FIGS. 4 (A) and 4 (B). Here, FIG. 4 is a diagram showing a modified example of the coating process, (A) is a first modified example, and (B) is a second modified example.

In the first modification shown in FIG. 4A, the position where the temporary fixing adhesive 4 is applied is changed to the position in the fourth row from the left. As described above, the position where the temporary fixing adhesive 4 is applied does not necessarily have to be the central portion of the adhesive surface 11a, but is a region close to the central portion (for example, the position of the second row or the fourth row). May be good. Even when the temporary fixing adhesive 4 is applied to such a position, the temporary fixing adhesive 4 can be sealed inside with the structural adhesive 3 in the bonding step Step 4.

In other words, the position where the temporary fixing adhesive 4 is applied is not preferably arranged in the first row or the fifth row. In this case, in the bonding step Step 4, the temporary fixing adhesive 4 is pushed out of the bonding surface 11a by the spreading of the structural adhesive 3, and the strength required for temporary fixing of the structure 1 can be maintained. It is predicted that it will not be possible.

In the second modification shown in FIG. 4B, the structural adhesive 3 and the temporary fixing adhesive 4 are diagonally applied. In the bonding step Step 4, if the structural adhesive 3 can be projected to the outer periphery of the adhesive surface 11a while sealing the temporary fixing adhesive 4, the direction in which the structural adhesive 3 and the temporary fixing adhesive 4 are applied is It can be set arbitrarily.

Next, the method of adhering the structure according to the second embodiment of the present invention will be described with reference to FIGS. 5 (A) to 6 (F). Here, FIG. 5 is an explanatory view showing a method of adhering a structure according to a second embodiment of the present invention, in which (A) shows a shape specifying step and a coating step, and (B) shows a bonding step. ..

The basic flow of the bonding method of the structure 1 according to the second embodiment is the same as that of the first embodiment shown in FIG. In this second embodiment, the shape of the adhesive portion 11 of the structure 1 in the shape specifying step Step 2 and the coating method of the structural adhesive 3 and the temporary fixing adhesive 4 in the coating step Step 3 are different.

In the shape specifying step Step 2 in the second embodiment, the adhesive portion 11 has a main adhesive surface 113 to which the structural adhesive 3 is applied and an auxiliary adhesive surface 114 to which the temporary fixing adhesive 4 is applied, and the main adhesive surface 113. This is a step of specifying the shape of the adhesive portion 11 so that a plurality of tabs 11b forming the auxiliary adhesive surface 114 are arranged on the outer periphery of the adhesive portion 11.

Specifically, as shown in FIG. 5A, in the shape specifying step Step 2, the main adhesive surface 113 is formed into a substantially rectangular shape, and the substantially rectangular tabs 11b are formed at the four corners thereof. Then, in the coating step Step 3, the structural adhesive 3 is linearly applied to the main adhesive surface 113 so as to form a plurality of rows. Further, the temporary fixing adhesive 4 is applied to the central portion of the tab 11b constituting the auxiliary adhesive surface 114.

Further, in the bonding step Step 4, the structural adhesive 3 is applied so that the structural adhesive 3 protrudes from the outer periphery of the adhesive surface 11a (main adhesive surface 113) as shown in FIG. 5 (B). In the present embodiment, the tab 11b (auxiliary adhesive surface 114) is a portion used for temporarily fixing the support member 1b, and is a portion that is not required to have a strength capable of holding the structure 1 after the structural adhesive 3 is cured.

Since the strength required for holding the structure 1 is secured by the main adhesive surface 113, it is sufficient that the structural adhesive 3 protrudes from the main adhesive surface 113. In the present embodiment, since a part of the structural adhesive 3 is located under the tab 11b, there is a possibility that the structural adhesive 3 shrinks and cracks when it is cured. However, as described above, since the tab 11b is not a portion that guarantees the strength for holding the structure 1, the influence on the strength holding is small.

Next, a modified example of the shape specifying step Step 2 and the coating step Step 3 in the second embodiment will be described with reference to FIGS. 6 (A) to 6 (F). Here, FIG. 6 is a diagram showing a modified example of the shape specifying step and the coating process, where (A) is a first modified example, (B) is a second modified example, and (C) is a third modified example. D) is a fourth modification, (E) is a fifth modification, and (F) is a sixth modification.

In the first modification shown in FIG. 6A, a substantially circular tab 11b is formed at a corner of the main adhesive surface 113. Although not shown, the tab 11b may have other shapes such as an elliptical shape and a polygonal shape.

In the second modification shown in FIG. 6B, tabs 11b are formed at the corners of the main adhesive surface 113 so as to extend in the left-right direction of the drawing. Although not shown, tabs 11b may be formed at the corners of the main adhesive surface 113 so as to extend in the vertical direction in the drawing. Further, although not shown, the tabs 11b may be formed so that some tabs 11b extend in the left-right direction of the drawing and the remaining tabs 11b extend in the vertical direction of the drawing.

In the third modification shown in FIG. 6C, a tab 11b is formed at the center of each side of the main adhesive surface 113. Although not shown, the shape of the tab 11b may be a circular shape, a polygonal shape, or the like. The tabs 11b do not necessarily have to be formed at the center of each side as long as they are arranged in a well-balanced manner in the vertical and horizontal directions.

In the fourth modification shown in FIG. 6D, two tabs 11b are formed on each of the left and right sides of the main bonding surface 113. In this modified example, it can be said that the tab 11b shown in FIG. 6B is repositioned toward the center along the left and right sides. Although not shown, two tabs 11b may be formed on each of the upper and lower sides of the main bonding surface 113 in the drawing. Further, the number of tabs 11b formed on each side may be three or more.

In the fifth modification shown in FIG. 6 (E), a total of eight tabs 11b are formed at the corners of the main adhesive surface 113 so as to extend in the left-right direction and the up-down direction in the figure. Further, in the sixth modification shown in FIG. 6 (F), the tab 11b shown in FIG. 6 (E) is repositioned toward the center along each side.

As described above, the number and arrangement of the tabs 11b are arbitrarily set according to conditions such as the coating area of the temporary fixing adhesive 4, the weight and the position of the center of gravity of the support member 1b, and the environment of the place where the structure 1 is bonded. be able to.

According to the method for adhering the structure 1 according to the second embodiment described above, the adhesive surface 11a has a size equal to or larger than the total area of the coating areas of the structural adhesive 3 and the temporary fixing adhesive 4. The adhesive portion 11 is provided so that the structural adhesive 3 protrudes from the outer periphery of the adhesive surface 11a at the time of adhesion, and the adhesive portion 11 adheres to the main adhesive surface 113 to which the structural adhesive 3 is applied for temporary fixing. The adhesive structure of the structure 1 having the auxiliary adhesive surface 114 to which the agent 4 is applied and having a plurality of tabs 11b forming the auxiliary adhesive surface 114 formed on the outer periphery of the main adhesive surface 113 is formed.

It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention, for example, the present invention can be applied to structures other than the fixtures of a ship. is there.
