However, in general, the joint material is a rubber-based member and is easily deteriorated by being affected by ultraviolet rays, temperature changes, and the like. Therefore, if the joint material deteriorates and its elasticity decreases after a certain period of time, the joint material may crack or peel off. When the joint material is cracked or peeled off, the joint is usually repaired by peeling off the old joint material and replacing it with a new joint material.

The repair of this joint is performed, for example, according to the procedure of steps T1 to T7 shown in FIG. That is, first, the old joint material is removed with a cutter knife or the like (step T1). Next, masking tape is applied around the end of the outer wall plate (step T2), and then the adhesive for joints is applied to the end face of the outer wall plate (step T3). In addition, an adhesive prevention tape for the joint material is attached to the convex portion of the hat joiner (step T4). After that, a new joint material is filled in the gap of the outer wall plate (step T5), and the joint material is pressed with a spatula or the like to form a groove-shaped joint (step T6). Finally, the masking tape is peeled off, and the joint material is waited to harden (step T7) to complete the repair of the joint.

The repair work of the above joint requires skillful work skills, requires a great deal of labor, and has a problem that the repair cost is high. In addition, even if the old joint material is replaced with a new joint material, the joint material is liable to deteriorate from the beginning, so there is a problem that it must be repaired again after a predetermined period (about 10 years) has passed.

The differences from the first embodiment will be mainly described.

<Joint cover member and joint repair method of the first embodiment>
The joint cover member of the first embodiment according to the present embodiment and the joint repair method using the joint cover member will be described with reference to FIGS. 1 to 6. FIG. 1 shows a schematic perspective view of the joint cover member of the first embodiment according to the present embodiment in an attached state.

The cross-sectional view of the plate is shown. FIG. 6 shows a flowchart showing a joint repair method using the joint cover member shown in FIG.

(Structure of joint cover member)
As shown in FIGS. 1 to 4, the joint cover member 5 of the first embodiment according to the present embodiment has a convex portion 21 of the hat joiner 2 fixed to the furring strip 11 of the building frame 1 and the convex portion. A joint used for repairing a joint 4 in which a rubber-like joint material 41 is filled in a gap between the ends 31 of the outer wall plate 3 fixed to the furring strip 11 with the ends 31 facing each other across the 21. It is a cover member. The outer wall plate 3 corresponds to, for example, ceramic siding or the like. Here, the outer wall plate 3 is formed in a rectangular plate shape, and its long side is extended in the vertical direction. The joint cover member 5 is attached along the long side of the outer wall plate 3.

Further, the joint cover member 5 is formed between a pair of external flange portions 511 that are in contact with the outer surface 311 of the end portion of the outer wall plate 3 and the external flange portions 511, and is separated from the joint material 41 and faces the joint material 41. It includes a cover body 51 having a joint facing portion 512, and an elastic body 52 joined to the back surface of the cover body 51 and in contact with the front surface of the joint material 41 and the end portion 31 of the outer wall plate 3. Further, the cover body 51 is fastened to the hat joiner 2 via a screw member 6 inserted from the outer surface of the joint facing portion 512 and engaged with the convex portion 21. The cover body 51 is preferably formed of, for example, an aluminum-zinc alloy-plated steel plate having high rust prevention performance (commonly referred to as "galvalume steel plate (registered trademark)"). The plate thickness of the cover body 51 is preferably, for example, about 0.3 to 0.5 mm. Here, the elastic body 52 is formed in a rectangular cross section, but the contact surface with the joint material 41 may be formed in a semi-cylindrical shape. This is because the joint material 41 is often recessed in an arc shape.

Further, the screw member 6 is penetrated from the head portion 61 to the outer surface of the screw portion 62 by intersecting the vertical hole 63 formed in the axial direction of the screw portion 62 and the vertical hole 63 on the back surface side of the convex portion 21. The adhesive 7 injected from the head opening 631 of the vertical hole 63 in a state where the horizontal hole 64 is provided and the screw portion 62 is engaged with the convex portion 21 is the screw penetrating portion of the horizontal hole 64. It is preferable that the screw portion 62 and the convex portion 21 are connected so as to protrude from 641. The screw portion 62 of the screw member 6 and the convex portion 21 of the hat joiner 2 can be more firmly connected via the adhesive 7, and the screw member 6 for fastening the joint cover member 5 is loosened due to a temperature change or the like. This is because the sealing property of the joint cover member 5 can be further improved. The screw member 6 is selected so that the screw portion 62 engages with the convex portion 21 of the hat joiner 2 but is not inserted into the building skeleton 1. Further, a driver groove is formed in the head 61.

Further, the elastic body 52 is preferably a rubber-based sponge member 52S in which bubbles are semi-continuously dispersed. The sponge member 52S is, for example, a soft semi-continuous foam rubber containing EPDM (ethylene, propylene, diene rubber) as a main component, and one having an acrylic pressure-sensitive adhesive formed on one side thereof is more preferable. The sponge member 52S can absorb rainwater that has entered through the gap between the cover body 51 and the outer wall plate 3, and when the surface of the joint material 41 comes into contact with the end portion 31 of the outer wall plate 3, the sponge surface is exposed. This is because it is flexibly deformed and easily adheres to the surface of the joint material 41 and the end portion 31 of the outer wall plate 3. Further, the sponge member 52S can enhance the heat insulating effect on the joint material 41 by the air layer contained in the air bubbles, and can delay the progress of deterioration of the joint material 41. The size of the bubbles in the sponge member 52S does not necessarily have to be uniform.

Further, in the cover body 51, it is preferable that the circumscribed flange portion 511 and the joint facing portion 512 are connected by a vertical wall portion 513 that stands up in the front and back directions of the outer wall plate 3. The circumscribed flange portion 511 formed parallel to the end outer surface 311 of the outer wall plate 3 and the joint facing portion 512 are connected by a vertical wall portion 513 formed perpendicular to the end outer surface 311. This is because the cross-sectional coefficient of the cover body 51 can be increased, and the rigidity of the cover body 51 against warpage, twisting, etc. in the longitudinal direction can be increased. Therefore, the sealing performance of the joint cover member 5 can be improved, the weight of the cover body 51 can be reduced, and the number of screw members 6 can be reduced. The circumscribed flange portion 511 is formed with a goby folded portion 511H in which an outer edge portion abutting on the outer surface 311 of the end portion of the outer wall plate 3 is bent inward and overlapped. By forming the goby folding portion 511H, rust prevention performance and safety performance can be improved.

Here, the joint facing portion 512 is formed with substantially the same width as the groove width 4H of the joint 4, and is connected to a pair of vertical wall portions 513 that stand up from the circumscribed flange portion 511 in the front direction of the outer wall plate 3. As a result, the rigidity of the cover body 51 can be further improved, and deformation of the joint facing portion 512 when the cover body 51 is fastened to the hat joiner 2 by the screw member 6 can be further avoided. Further, the sponge member 52S, which is an elastic body 52, is fitted in the gap between the vertical wall portions 513 and is joined to the back surface of the joint facing portion 512. As a result, when the cover body 51 is fastened to the hat joiner 2 by the screw member 6, the elastic body 52 (sponge member 52S) is compressed so that the surface of the joint material 41 and the end portion 31 of the outer wall plate 3 are further brought into close contact with each other. The sealing property can be improved.

(Joint repair method using joint cover member)
As shown in FIGS. 3, 5, and 6, first, in the cover body forming step S1, the steel plate cut to a predetermined width and length is bent to form the cover body 51 of the joint cover member 5. In the cover body 51, after bending the goby folding portion 511H, the circumscribed flange portion 511, the vertical wall portion 513, and the joint facing portion 512 into a predetermined hat cross section, only the goby folding portion 511H is moved to the back surface side of the circumscribed flange portion 511. It is formed by hemming bending so as to overlap. After that, a screw pilot hole 512P is formed in the joint facing portion 512 corresponding to the fastening position of the screw member 6.

Next, in the elastic body forming step S2, the elastic body 52 (sponge member 52S) formed to have a predetermined width is cut into a predetermined length. The thickness of the elastic body 52 (sponge member 52S) is selected according to the degree of shrinkage of the joint material 41 with respect to the end outer surface 311 of the outer wall plate 3. Further, the elastic body 52 (sponge member 52S) is formed with a notch portion 521 corresponding to the fastening position of the screw member 6 (screw pilot hole 512P formed in the joint facing portion 512). The notch portion 521 is preferably formed in a V shape or a U shape so as to avoid being caught by the screw groove of the screw portion 62.

Next, in the elastic body joining step S3, the elastic body 52 (sponge member 52S) is joined to the back surface of the cover body 51. Here, the elastic body 52 (sponge member 52S) is a soft semi-continuous foam rubber containing EPDM (ethylene, propylene, diene rubber) as a main component, and an acrylic adhesive is formed on one side of the elastic body 52 (sponge member 52S). It is attached to the back surface of the facing portion 512 via an acrylic adhesive 522. Further, in the state where the elastic body 52 (sponge member 52S) is attached to the joint facing portion 512 of the cover body 51, the contact surface 523 that comes into contact with the joint material 41 and the outer wall plate 3 is outward from the circumscribed flange portion 511. It protrudes to.

Next, in the cover fastening step S4, the cover body 51 to which the elastic body 52 (sponge member 52S) is joined is engaged with the convex portion 21 of the hat joiner 2 via the screw member 6. The screw member 6 has a vertical hole 63 formed in the axial direction of the screw portion 62 from the head portion 61 and a horizontal hole that intersects the vertical hole 63 on the back surface side of the convex portion 21 and penetrates to the outer surface of the screw portion 62. Using a screw provided with 64, the screw is inserted through the screw pilot hole 512P formed in the joint facing portion 512. Further, the adhesive 7 is injected from the head opening 631 of the vertical hole 63 in a state where the screw portion 62 is engaged with the convex portion 21 of the hat joiner 2. The adhesive 7 protrudes from the screw penetrating portion 641 of the lateral hole 64 and solidifies in a state where the screw portion 62 and the convex portion 21 are connected.

In the place where the joint material 41 has deteriorated by the above steps, the joint cover member 5 is simply attached to the hat joiner 2 by the screw member 6 without replacing the deteriorated joint material 41 with a new joint material. It can be repaired.

<Joint cover member of the second embodiment>
The joint cover member of the second embodiment according to the present embodiment will be described with reference to FIG. 7. 7A and 7B are cross-sectional views showing before and after mounting of the joint cover member of the second embodiment according to the present embodiment, in which FIG. 7A shows a cross-sectional view of the joint cover member before mounting, and FIG. 7B shows a cross-sectional view after mounting. The cross-sectional view of the joint cover member and the outer wall plate is shown. Here, regarding the joint cover member of the second embodiment, common reference numerals are given to the common points with the first embodiment, and the explanation thereof is omitted in principle, focusing on the differences from the first embodiment. Explain to. Further, since the joint repair method using the joint cover member of the second embodiment is common to the joint repair method using the joint cover member of the first embodiment described above, the description thereof will be omitted.

(Structure of joint cover member)
As shown in FIG. 7, the joint cover member 5B of the second embodiment according to the present embodiment sandwiches the convex portion 21 of the hat joiner 2 fixed to the furring strip 11 of the building frame 1 and the convex portion 21. A joint cover member used for repairing a joint 4 in which a rubber-like joint material 41 is filled in a gap between the ends 31 of the outer wall plate 3 fixed to the furring strip 11 with the ends 31 facing each other. The joint cover member 5B has a pair of external flange portions 511 that are in contact with the outer surface 311 of the end portion of the outer wall plate 3, and are formed between the external flange portions 511 and face each other at a distance from the joint material 41. A cover body 51 having a joint facing portion 512 and an elastic body 52B joined to the back surface of the cover body 51 and in contact with the front surface of the joint material 41 and the end portion 31 of the outer wall plate 3 are provided. Further, the cover body 51 is fastened to the hat joiner 2 via a screw member 6 inserted from the outer surface of the joint facing portion 512 and engaged with the convex portion 21. Further, the joint facing portion 512 is formed with substantially the same width as the groove width 4H of the joint 4, and is connected to a pair of vertical wall portions 513 that stand up from the circumscribed flange portion 511 in the front direction of the outer wall plate 3. The above configuration is basically the same as that of the first embodiment.

However, in the second embodiment, the elastic body 52B is different from the first embodiment in that the elastic body 52B is joined to the back surface of the circumscribed flange portion 511 across the gap between the vertical wall portions 513. That is, in the second embodiment, the elastic body 52B is formed to have a wide width, and a space is formed in the gap between the vertical wall portions 513. According to the above configuration, when the cover body 51 is fastened to the hat joiner 2 by the screw member 6, the elastic body 52B is compressed by the circumscribed flange portion 511 and brought into close contact with the surface of the joint material 41 and the end portion 31 of the outer wall plate 3. In addition to enhancing the sealing property, a space can be formed between the joint facing portion 512 and the elastic body 52B to enhance the heat insulating effect.

The elastic body 52B is preferably a rubber-based sponge member 52SB in which bubbles are semi-continuously dispersed.
