Abstract

PROBLEM TO BE SOLVED: To provide a structure which can ensure the water tight performance of a joined part. SOLUTION: The back surfaces of a pair of band plates 3 arranged so as to be a L letter shape section are mutually integrated connectingly by a connection hardware 4 and also at least one side of the back surface edge parts of a pair of band plate positioned on a back surface crossing part is lost and a water tight material 5 is filled in the groove 6 formed by this loss. Thereby, as at least one side of the back surface edge part of the band plate positioned on the back surface crossing part of a pair of band plates 3 mutually integrated connectingly is lost and the water tight material 5 is filled in the groove 6 formed by this loss, even if a clearance δ is generated on the corner by the machining accuracy of the joined surface of a pair of band plates 3 and the warp of the band plate 3, the clearance is perfectly sealed by the water tight material 5 filled in the groove 6. In other words, by filling up the water tight material 5 filled in the groove 6, the clearance δ can be buried in the range of the size (t) of the water tight material 5 of the direction orthogonally crossing with the joined surface 3a of the band plate 3 and then the water tightness is garanteed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a corner cover according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a cross-sectional plan view showing a structure of a corner cover according to an embodiment of the present invention, FIG. 2 is a cross-sectional plan view showing a construction state of the corner cover of this embodiment, and FIG. FIG. 3 is a plan view of a band plate to be configured. As shown in FIG. 2, the outer wall panels 1 and 1 are arranged in a direction orthogonal to each other, and a gap formed between the outer wall panels 1 and 1 at a corner is covered by a corner cover 2.

The corner cover 2 is, as shown in FIG.
The vehicle includes a pair of band plates 3 and 3 serving as an exterior plate, a connecting hardware 4 and a watertight material 5 for connecting the pair of band plates 3 and 3. The strip 3 is formed of ceramic or the like, and the outer wall panel 1 is formed.
If the same material is used as the exterior plate 1b, a sense of unity can be provided. Further, since the end faces (joining surfaces) 3a are brought into contact with each other so that the pair of strips 3 and 3 have an L-shaped cross section, the end faces 3a are inclined as shown in FIG. Further, at least one of the pair of band plate back surface edge portions located at the back surface crossing portion of the pair of band plates 3 and 3 is deficient, and a groove 6 is formed in the back surface crossing portion along the vertical direction by the deficient portion 3b. Is done. In this case, the edge of the rear surface of the band plate 3 is cut off so that a surface along the width direction and the thickness direction of the band plate 3 is formed.
In addition, as shown in FIG.
When b and 3b are formed, the groove 6 is formed by the mutually lacking portions 3b and 3b. When only the one strip 3 has the missing portion 3b, the missing portion 3b and the end face of the other strip 3 are formed. 3
The groove 6 is formed by a. The groove 6 formed by the defect is filled with the watertight material 5 formed of an adhesive elastic resin or the like.

The connecting metal member 4 is an angle-shaped metal member capable of connecting the pair of band plates 3 and 3 to each other on the back surface. In this case, the two pieces of the connecting hardware 4 are respectively brought into contact with the back surfaces of the pair of strips 3, 3, and the connecting hardware 4 is fixed by the rivets 7 embedded in the strip 3, whereby the pair of strips 3, 3 are fixed. 3 are connected and integrated. Instead of the rivet 7, the connecting hardware 4 may be fixed with a fixing tool such as a nail. The metal fitting 4 is elongated in the vertical direction so as to cover the groove 6 over the entire length.

Further, as shown in FIG. 2, a temporary fixing metal 8 is attached to the back surface of the corner cover 2 and the outer wall panel 1 is provided.
And the hole 10 provided in the frame 1a. In the construction state, both side edges of the corner cover 2 are brought into contact with the frame 1a of the outer wall panel 1 and the temporary fixing hardware 8 is inserted into the holes 10.
To be engaged. At this time, the surfaces of the band plate 3 of the corner cover 2 and the exterior plate 1b of the outer wall panel 1 are substantially flush,
At the joint between the two members 1b and 3, a bond breaker 11,
The caulking 12 and the joint makeup cover 13 are attached.

Next, the operation of the corner cover will be described. As shown in FIG. 1, even if a gap δ occurs due to a variation in processing accuracy of the joining surface 3 a of the band plate 3 or a warp of the band plate 3, since the groove 6 is filled with the watertight material 5, the band plate is filled. 3
The gap δ can be filled in the range of the dimension t of the watertight material 5 in the direction orthogonal to the joining surface 3a. As described above, according to this embodiment, a pair of strips 3,
Since at least one of the pair of back edge portions of the pair of strips located at the intersection of the back surface 3 is cut off and the watertight material 5 is filled in the groove 6 formed by the cut, even if a gap δ occurs at the corner portion Is completely sealed by the watertight material 5 filled in the groove 6.

[0014] Further, if the metal plate (fixing tool) is bonded to the band plate 3 itself by driving due to the defect, the strength of the band plate 3 itself is reduced, and cracks and cracks are induced. By connecting the pair of band plates 3 and 3 to each other on the back side, fixing at a position where no deficiency occurs is possible, so that the strength of the band plate 3 itself does not decrease, and further, a corner having an L-shaped cross section is used. The effect of retaining and reinforcing the shape of the cover is enhanced.

When the bonding surface 3a is bonded with an adhesive, it is difficult to maintain the accuracy of the bonding surface and the amount of the adhesive applied to secure the smoothness and the bonding strength of the bonding surface of the adhesive, and to secure the bonding strength. Although the production lead time is prolonged due to the required curing and the production cost is increased due to the increase in the number of management steps, the use of the connection hardware 4 solves such a problem.

Furthermore, since the watertight material 5 of the adhesive elastic resin is filled in the groove 6 of the corner cover, even if both the strips 3 and 3 are deformed by an external force and both angles and the like change, the change follows. Thus, the watertight material 5 is not damaged. Also,
Since the groove 6 is filled with the watertight material 5 made of an adhesive elastic resin, the following range is sufficiently ensured. In addition, since the watertight material 5 is filled from the back surface and covered with the connecting hardware 4 to prevent the watertight material 5 from adhering to the outside, curing until particularly hardening of the surface is unnecessary, and the construction period can be shortened. The connecting hardware 4 may be a piece material.

The shape of the defective portion 3b formed in the strip 3 is not limited to the above-mentioned shape. For example, as shown in FIG. 4, the end face 3a may be formed into a shape in which the edge of the back surface of the strip is chamfered.
Further, as shown in FIG. 5, the shape may be such that the corner of the missing portion 3b is obtuse.

[0018]

According to the structure of the corner cover of the present invention, at least one of the pair of back side edges of the pair of strips located at the intersection of the back sides of the pair of strips connected and integrated with each other is cut off, and this cut off is made. Is filled with watertight material, so even if there is a gap in the corner part due to the processing accuracy of the joining surface of the pair of strips or warpage of the strip, etc., the watertight material filled in the groove part completely Sealed. That is, by filling the groove with the watertight material, it is possible to fill the gap in the range of the size of the watertight material in the direction orthogonal to the joining surface of the strip,
Water tightness is guaranteed.

According to the second aspect of the present invention, when the metal plate (fixing tool) is joined to the band plate itself by driving due to the defect, the strength of the band plate itself is reduced, and cracks and cracks are induced.
By connecting the pair of strips to each other on the back surface using the connecting hardware, it is possible to fix at a position where there is no defect, so that the strength of the strip itself does not decrease, and of course, a corner cover having an L-shaped cross section. And the effect of retaining and reinforcing the shape is enhanced.

According to the third aspect of the present invention, since the groove of the corner cover is filled with the watertight material of the adhesive elastic resin, even if both the strips are deformed by external force and both angles and the like change, the change follows the change. The watertight material is not damaged. In addition, since the groove portion is filled with the watertight material of the adhesive elastic resin, the following range is sufficiently ensured.
