Description

  The present invention relates to an inner joint for eaves that can connect eaves and eaves without impairing the beauty.

  Since the conventional outer joint for eaves is exposed to the outer surface of the connecting part of the eaves and impairs the appearance, the outer joint body of the outer shape along the inner surface of the eaves main body composed of the outer piece, the bottom piece, and the inner piece An inner joint for eaves has been proposed in which a movable part for bonding that can be cut and raised by cutting out from the upper end to the bottom piece of the outer side is proposed (Patent Document 1).

  This joint has the advantage that the working time can be shortened because the joint body and the movable part for bonding are integrally formed. On the other hand, the temporary fixing time must be shortened to prevent the adhesive from drying. There was a problem that it was difficult to adjust the overall balance of the eaves and connect them. For this reason, there is often a gap between the ends of the eaves to be connected. In particular, when this gap is viewed from the ground (front), the ears of both connected eaves There was a problem that the gap between the ears was conspicuous and the aesthetic appearance was impaired.

The problem that a gap is generated between the ends of the eaves and the aesthetic appearance is impaired is a problem that can occur in all of the inner joints. Such a problem cannot be neglected in view of the trend of emphasizing the appearance of houses in recent years.
JP 2002-13259 A

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an eaves-inner joint having a good appearance with no conspicuous gap generated between the connected eaves end portions.

  In order to achieve the above-mentioned object, the eaves-inner joint according to the present invention is internally fitted along the inner surfaces of both eaves end portions to be connected to conceal the gap generated at the butted portion of both eaves eaves The blindfold is provided at the upper end of the front surface.

In the inner joint for eaves of the present invention, both the eaves end at the opening of the intermediate portion of the temporary fixing member and the temporary fixing member fitted along the inner surface of the both ends of the eaves to be connected A blindfold piece for concealing a gap generated at the abutting portion of both eaves ridges is provided at the upper end of the front surface of the temporary fixing member or the bonding member. preferable. Further, the temporary fixing member and the bonding member are preferably formed separately, the engaging ear edge is formed so as to substantially follow the cross-sectional shape of the front ear part of the eaves, and the upper end of the engaging ear edge is More preferably, the cross-sectional shape is curved in the inner direction of the eaves. Furthermore, the width of the blindfold is preferably 5 to 20 mm.
The bonding member may be formed continuously with the temporary fixing member at the rear end.

  Since the inner joint for eaves of the present invention is an inner joint, it is not exposed to the outer surface of the connecting portion of the eaves unlike the conventional outer joint, and the appearance is not impaired. In addition, since a blindfold is provided at the upper front end of the inner joint for eaves to hide the gap generated at the abutting part of both eaves, the gap generated between the eaves end and the eaves end is on the inside (back ) So that the gap is not noticeable even when viewed from the outside (front).

  Further, a temporary fixing member that is internally fitted along the inner surfaces of both eave ridge ends to be connected, and an adhesive along the inner surfaces of both eave ridge ends at the opening of the intermediate portion of the temporary fixing member. The inner joint for the eaves eaves provided on the upper front end of the temporary fixing member or the bonding member is made up of the blindfolds. In addition to obtaining the same effect of concealing gaps as above, the balance of the entire eaves is adjusted with the temporary fixing members fitted inside the butted parts of both eaves to be connected. And the position of the temporary fixing member can be sufficiently adjusted. In particular, the inner joint for eaves in which the temporary fixing member and the bonding member are separately formed has an adhesive on the outer surface of the bonding member after the position adjustment. And apply the adhesive member into the opening of the temporary fixing member. Since the eaves can be connected by bonding the inner surface of the mating part and the bonding member, the adhesive applied to the outer surface of the bonding member is dried before fitting into the opening of the temporary fixing member. There is also an effect that the connection work can be performed without worrying that the adhesive adheres to unnecessary portions on the inner surface of the eaves when the position of the temporary fixing member is adjusted.

  Further, the inner joint for eaves ridges is formed so that the engagement ear edge substantially conforms to the cross-sectional shape of the front ear part of the eaves rod, and the upper end of the engagement ear edge is curved in the inner direction of the eaves ridge. Since the finger is easily hooked on the upper end of the engagement ear edge, the workability is improved.

  Furthermore, the inner joint for eaves eaves whose width of the blindfold is 5 to 20 mm, the width of the blindfold is not wider than necessary, and the end portion above the fitting step portion of the joint body and the eaves end portion Since the gap is wide enough to cover the gap formed between them from behind, the gap can be reliably hidden, and the amount of resin used can be saved.

  Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings, but the present invention is not limited to these embodiments.

  FIG. 1 is a perspective view of an inner joint for eaves-holding according to an embodiment of the present invention, FIG. 2 is a perspective view of a temporary fixing member for the inner joint, and FIG. 3 is a perspective view of a bonding member for the inner joint. 4 is a perspective view showing a state where the temporary fixing member is fitted inside the butted end of the eaves and temporarily fixed, and FIG. 5 is a perspective view showing a state where the eaves are connected by the inner joint.

  An eaves-inner joint A shown in FIG. 1 (hereinafter simply referred to as an inner joint) is fitted into a synthetic resin temporary fixing member 1 shown in FIG. 2 and an opening 13 in the middle of the temporary fixing member 1. 3. This is composed of the synthetic resin bonding member 2 shown in FIG. 3, and connects the eaves 30 and the eaves 30 from the inside as shown in FIG.

  The temporary fixing member 1 shown in FIGS. 2 and 4 includes a front plate 10, a bottom plate 11 and a rear plate 12 along the inner surface shape of the eaves 30 and 30 to be connected. Is formed with an engagement ear edge 10a to be engaged with the front ear portion 30a of the eaves rod 30 from the inside, and a blindfold piece 3 is integrally provided at an intermediate portion of the engagement ear edge 10a. . Further, an engagement ear edge 12b is formed at the upper end of the rear surface plate 12 to be engaged with the rear ear portion 30b of the eaves rod 30 from the inside, leaving the engagement ear edges 10a and 12b, An opening 13 into which the bonding member 2 is fitted is formed in an intermediate portion of the bottom plate 11 and the rear plate 12 in the length direction, and the front plate 10, the bottom plate 11, and the rear plate 12 are sandwiched between the openings 13. Is divided into two in the length direction.

  The longitudinal ends 10 and 10 of the front plate 10 divided into two and the longitudinal ends 12 and 12 of the rear plate divided into two are connected by reinforcing members 5 and 5. This reinforcing member 5 is a plate-like body formed integrally with the front plate 10 and the rear plate 12, and external force is applied from the front and rear to both ends in the longitudinal direction of the front plate 10 and the rear plate 12 divided into two. Also, both end portions in the length direction are formed so as not to be deformed so as to incline toward the inner side of the eaves. On the other hand, since the front plate 10 and the rear plate 12 are difficult to fit into the eaves bowl 30 unless they are elastic to the inside to some extent, the reinforcing member 5 is approximately 1 in height of the front plate 10 and the rear plate 12. It is preferably provided at a height of about / 2.

  The engagement ear edge 10a formed at the upper end of the front plate 10 of the temporary fixing member 1 is curved so as to substantially follow the cross-sectional shape of the front ear portion 30a of the eaves rod 30, and the upper end of the engagement ear edge 10a is It is provided with a substantially S-shaped cross-sectional shape that is curved inwardly of the eaves so as to gradually move away from the front ear portion 30a, and by using such a shape, when the temporary fixing member 1 is fitted, Also when removing, it becomes easy for a finger to be caught by the upper end part of the front ear | edge part 30a, and workability | operativity improves. The engagement ear edge 12b formed at the upper end of the rear plate 12 has a substantially L-shaped cross-sectional shape corresponding to the rear ear portion 30b of the eaves rod 30. Then, as shown in FIG. 5, the position corresponding to the butted portion of the eaves rods 30 and 30 of the engagement ear edge 10a (in this embodiment, the engagement ear edge 10a of the front plate 10 of the temporary fixing member 1). A blindfold piece 3 is erected upward from an intermediate portion in the length direction. When the eaves rod 30 and the eaves rod 30 are connected to each other, the blindfold piece 3 causes a gap S generated between the upper end portion of the eaves ear portion 30a and the upper end portion of the eaves ear portion 30a from behind. By covering, it hides so that it is not conspicuous, and covers from the back to the upper end of the eaves ear part 30a. Moreover, the width of the blindfold 3 is formed within a range of 5 to 20 mm sufficient to cover the gap S from behind, and is not formed wider than necessary, so that the amount of resin used can be saved. You can also.

  In this embodiment, the blindfold 3 is provided in the middle part of the engagement ear edge 10a of the front plate 10a. However, when the gap S is located in a part other than the middle part of the engagement ear edge 10a, it is adjusted accordingly. Needless to say, it should be provided. Moreover, the shape of the blindfold 3 may be any shape as long as it covers the gap S from behind. For example, the blindfold 3 having the same shape as the ear 30a of the eaves 30 is formed on the ear 30a of the eaves 30. The gap S may be hidden along the line.

  In addition, the adhesive applied to the bonding member 2 when the bonding member 2 is fitted into the opening 13 at the middle in the length direction of the engagement ear edge 10 a at the upper end of the front plate 10 of the temporary fixing member 1. A protruding piece 4 for preventing scraping is provided to protrude rearward. The tip surface of the protruding piece 4 is formed in a rounded curved surface so that the bonding member 2 can be smoothly fitted into the opening 13 with a small resistance, and in particular, the R surface in the sliding direction when fitting. It is even better to have it formed. Further, the projecting dimension of the protruding piece 4 is such that when the bonding member 2 is fitted, the protruding edge 4 is placed between the engagement ear edge 10 a at the upper end of the front plate 10 of the temporary fixing member 1 and the front plate portion 20 of the bonding member 2. A clearance larger than the coating thickness of the adhesive is formed, and the corner portion where the front plate portion 20 rises substantially vertically from the front end of the bottom plate portion 21 of the bonding member 2 is in sliding contact with the same corner portion of the eaves rod 30. There are no projecting dimensions. Specifically, a projecting dimension of about 2 to 25 mm is optimal.

  In addition, the mark which shows the position which matches the edge part of the eaves rods 30 and 30 in the length direction center of the engagement ear edge 10a of the front plate 10 of the temporary fixing member 1 or the engagement ear edge 12b of the rear surface plate 12 is shown. In that case, there is an advantage that the alignment becomes easy and the workability is improved.

  As shown in FIGS. 3 and 5, the bonding member 2 includes a front plate portion 20, a bottom plate portion 21, and a rear plate portion 22 along the inner surface shape of the eaves rod 30 to be connected. The member 1 is adapted to be fitted into an opening 13 formed in the middle portion in the length direction.

  The shape of the front plate portion 20, the bottom plate portion 21, and the rear plate portion 22 of the bonding member 2 is substantially the same as the front plate 10, the bottom plate 11, and the rear plate 12 of the temporary fixing member 1. An engagement edge 20 a having a substantially S-shaped cross section is formed at the upper end of the plate portion 20 to be engaged with the engagement ear edge 10 a at the upper end of the front plate 10 of the temporary fixing member 1 from the inside.

  A concave notch 6 is formed at an intermediate position in the length direction of the engaging edge 20a (a position corresponding to the protruding piece 4). When the bonding member 2 is fitted into the opening 13, the protrusion The piece 4 fits into the notch 6.

  On the other hand, on the outer surface of the bonding member 2, four grooves 2a extending from the front plate portion 20 through the bottom plate portion 21 to the rear plate portion 22 are provided, and in the four grooves 2a, synthetic rubber is provided. The waterproof packing 2b which consists of etc. is inserted. In addition, you may increase / decrease the number of the groove | channel 2a and the packing 2b suitably.

  As described above, if the groove 2a is provided on the outer surface of the bonding member 2 and the packing 2b is fitted, the bonding member 2 is not sufficiently bonded to the inner surface of the connection end portion of the eaves bowl 30. However, since the packing 2b is in close contact with the inner surface of the connecting end portion of the eaves rod 30 and exhibits a waterproof effect, it is possible to prevent water from leaking out from the connecting portion of the eave rod 30 and excessive adhesive. Even if it is applied, the adhesive can be prevented from protruding outside the packing 2b, so that the adhesive does not leak from the butted portions of the eaves 30 and 30. And even if some shift | offset | difference arises in the butt | matching edge part of the eaves bowl 30 and 30, a shift | offset | difference can also be corrected with the flexible packing 2b.

  In order to connect the eaves 30 and 30 using the inner joint A as described above, the ends of the eaves 30 and 30 are butted together as shown in FIG. The engagement edge edges 10a and 12b are engaged with the ear portions 30a and 30b of the eaves rods 30 and 30 from the inner lower side and temporarily fixed. And in this temporarily fixed state, the balance of the whole eaves 30 and 30 connected is fully adjusted.

  Next, an adhesive is applied to the outer surface of the bonding member 2, and the upper end of the rear plate portion 22 of the bonding member 2 is locked to the bottom surface of the engagement ear edge 12 b of the rear plate 12. The bonding member 2 is rotated downward as a fulcrum, and the engagement edge 20a at the upper end of the front plate 20 is engaged with the front ear 30a of the eaves 30 using the elastic deformation of the bonding member 2. The adhesive member 2 is fitted into the opening 13 by engaging with the auricle edge 10a from the lower side inside, and the adhesive member 2 is bonded to the inner surface of the butted end portion of the eaves rod 30 and 30, and both eave rods 30 and 30 are attached. Connect. At this time, the protruding piece 4 provided at the upper end of the front plate 10 is in sliding contact with the outer surface of the bonding member 2, and the engagement ear edge 10 a at the upper end of the front plate 10 and the outer surface of the front plate portion 20 of the bonding member 2 In order to ensure the clearance between the two, the clearance prevents the adhesive applied to the bonding member 2 from being scraped off.

As described above, the inner joint A adjusts the balance of the entire eaves by temporarily fixing the ends of the eaves 30 and 30 to be connected by the temporary fixing member 1, so that the balance is carefully taken over time. After that, the adhesive can be applied to the bonding member 2 and fitted into the opening 13 to bond the ends of the eaves 30 and 30, so that the adhesive does not have to dry before bonding. In addition, the adhesive member 2 can be prevented from being scraped off by the protruding pieces 4 when the adhesive member 2 is fitted into the opening 13 as described above. The eaves 30 and 30 can be connected by firmly and watertightly adhering to each other, and the workability is very good. Moreover, if there is no blindfold piece 3, since the gap S generated between the upper end portion of the eaves hook portion 30a and the upper end portion of the eaves hook portion 30a is conspicuous, the aesthetic appearance is impaired. When the blindfold 3 is formed as described above, the gap S is covered from behind, and the gap S is not conspicuous even when viewed from the front. Since it cannot be seen from below, the appearance of the connecting portion of the eaves 30 and 30 is good, and the aesthetic appearance of the building is not impaired. In particular, the blindfold piece 3 in this embodiment is erected up to the upper end of the front ear portion 30a of the eaves bowl 30, and its width is set within a range of 5 to 20 mm, so the effect of concealing the gap S is remarkable. It is.
In the inner joint A for eaves eaves according to the present embodiment, the temporary fixing member 1 and the bonding member 2 are formed separately, but the bonding member 2 is continuously connected to the temporary fixing member 1 by the plate portion 22 thereafter. May be formed.
