Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connection device for eaves gutters, particularly inorganic eaves gutters that are more rigid and heavier than eaves gutters made of synthetic resin molded products.

[Conventional technology]

Eaves gutters that collect rainwater that falls on the roof and guide it to the vertical gutters are commonly made of synthetic resin molded products, but with the trend towards luxury in recent years, eaves gutters have been made to be less conspicuous. There is a growing demand for eaves to be constructed to give a smooth finish to the eaves. The above-mentioned inorganic eaves gutters were developed by the applicant to meet such demands, and are particularly suitable for use in ceramic houses.

FIG. 9 shows an example in which an inorganic eaves gutter 1 is attached to a fascia 2 at the eaves. In this example, an inverted L-shaped upper protrusion 4, which is integrally provided on the upper part of an inorganic eaves gutter 1 having a large number of hollow parts 3, is attached to the fascia 2 by a screw 6.
After being engaged and supported by the engaging tool 8 fixed by the
is pressed against the fascia 2 with an engaging tool 9 and fixed with a mounting screw 7. When the inorganic eaves gutter 1 is installed in this way, the inorganic eaves gutter 1 and the fascia 2 create a sense of unity, the inorganic eaves gutter 1 becomes less noticeable, and the eaves end has a clean and elegant finish. I can feel it.

However, the inorganic eaves gutter 1 is made of a cement-based material molded into a concave groove shape, and is considerably heavier and more rigid than the eave gutter made of conventional synthetic resin molded products, making it susceptible to deformation. Therefore, not only in the state illustrated in Figure 9 but also in any currently conceivable mounting structure, both heavy inorganic eaves gutters cannot be accurately connected at the connection point between the inorganic eaves gutters. It is difficult to align the positions, and even if the alignment can be done accurately, the ends of the two sides will not match due to differences in shape due to molding errors of the inorganic eaves gutters on both sides, unevenness of the fascia, etc., and furthermore, due to aging after installation, The position gradually shifts. Additionally, inorganic eaves gutters have the property of shrinking due to water absorption due to the characteristics of the material. Mismatching, misalignment, or shrinkage of these ends can cause water leakage at the connection. Therefore, even if a two-component adhesive is used to bond the inorganic eaves gutters on both sides, the adhesive cannot absorb the misalignment, misalignment, or shrinkage of the ends, resulting in the water leakage. It is impossible to reliably prevent this over a long period of time.

Therefore, the applicant has proposed a means for accurately positioning the respective inorganic eaves gutters connected to each other,
Various studies were conducted on ways to absorb the misalignment between the two inorganic eaves gutters.

The present invention was completed as a result of these studies, and provides a connecting device that can effectively absorb the mismatch in shape and misalignment between the two inorganic eaves gutters, and can be easily molded from synthetic resin. The purpose is to

[Means for solving problems]

In order to solve the above problems, the eaves gutter connection device of the present invention consists of a pair of connecting members fixed to the ends of each eaves gutter to be connected to each other, and these connecting members are fixed to one end of each eaves gutter. When the convex portion of the other connecting member is fitted into the recess provided in the connecting member, a space for filling the sealant to hold the sealant is formed between both connecting members. The main point lies in the way it is structured.

[Effect]

In the above configuration, if the space for sealing material filling formed between both connecting members is filled with sealant, there may be mismatches in shape or misalignment between the inorganic eaves gutters that are connected to each other, or the installation Even if the position shifts over time or the inorganic eaves guttering shrinks due to water absorption, the sealant will always maintain the watertightness required at the connection, and water will not leak from the connection. No worries. Furthermore, since the sealing material is filled in the space, the sealing material is prevented from protruding from between the two connecting members, and furthermore, the sealing material is not exposed to the sun or the outside air.
The sealant exhibits a water leakage prevention effect over a long period of time without degrading its performance.

〔Example〕

FIG. 1 is a perspective view showing a pair of connecting members 11 and 12 constituting a connecting device according to an embodiment of the present invention.

One of the connection members 11 includes a mounting part 15 having a U-shaped cross section formed by mounting mounting plates 14, 14 protruding from a backing plate part 13, and a mounting plate part 14 at both ends of the mounting part 15 in the width direction. It consists of plate-like protrusions 16, 16 protruding in the opposite direction to the protrusion 1.
6, 16 and the backing plate part 13 form a recessed part 17, and its overall shape is an H-shaped cross section. In addition, this connecting member 11 has a ninth shape when viewed from the front.
Although the shape is similar to the end face shape of the inorganic eaves gutter 1 illustrated in the figure, the mounting plate portion 14 on the outside of the portion corresponding to the upper protrusion 4 and lower protrusion 5 of the inorganic eaves gutter 1 is omitted. The upper protrusion 4 and the lower protrusion 5 can be inserted therein. Note that the rear side of the outer mounting plate portion 14 may be completely removed.

The other connecting member 12 has a pair of plate-shaped protrusions 21, 21 protruding at an interval from a mounting part 20 having a U-shaped cross section, which is formed by protruding mounting plate parts 19, 19 from a backing plate part 18. It will be set up. Similarly to the above, this connecting member 12 has a shape similar to the end face shape of the inorganic eaves gutter 1 illustrated in FIG. 9 when viewed from the front. The upper projection 4 is removed by removing the corresponding portion of the outer mounting plate portion 4.
and a lower protrusion 5 can be inserted therein.

FIG. 2 shows the state in which the above connection device is used. As shown in the figure, the attachment part 15 of one of the connection members 11 is fitted into the end of the inorganic eaves gutter 1,
A silicone-based or urethane-based sealant 22 is used in the gap l between the mounting plate parts 14, 14 and the inorganic eaves gutter 1.
is filled. The attachment part 20 of the other connection member 12 is fitted into the end of another inorganic eaves gutter 1,
A gap l between the mounting plate parts 19, 19 and the inorganic eaves gutter 1 is filled with a sealing material 23. Also,
A sealing material 24 is filled in a space formed when the convex portions 21, 21 of the other connecting member 12 are fitted into the recessed portion 17 of one connecting member 11.

According to such a configuration, even if a positional shift occurs between the inorganic eaves gutters 1, 1 that are connected to each other,
The sealing material 24 filled in the space is deformed according to the degree of the positional shift without forming a gap to ensure the necessary watertightness. Furthermore, even if the inorganic eaves gutters 1, 1 absorb water and contract, the sealing material 24 deforms according to the extent of the contraction without creating any gaps, thereby ensuring the necessary watertightness.

By the way, the work of attaching one connection member 11 to the inorganic eaves gutter 1 via the sealing material 22 and the work of attaching the other connection member 12 to another inorganic eaves gutter 1 via the sealing material 23 are both Do it on the ground. However, one connection member 1
The convex part 21 of the other connecting member 12 is connected to the concave part 17 of one.
The work of fitting each inorganic eaves gutter 1, 1
This is done by sliding these inorganic eaves gutters 1, 1 laterally while being engaged and supported by the engaging tool 8 shown in FIG. Therefore, in order to fill the space with the sealant 24, the sealant 24 is held in the recess 17 or between the convex parts 21 and 21 before the slide. At the same time, the sealing material 24 is crushed to fill the space. In this case, even if there is a positional shift between the two inorganic eaves gutters 1, 1, the blank space is completely filled in by the sealing material 24.

Note that it is customary to apply a sealer coating to the surface of the inorganic eaves gutter 1 to make it waterproof, but when connected using a connecting device as described above,
It is preferable to apply a sealer coating to the connecting portions so that the respective connecting members 11 and 12 are not noticeable.

In such a connection device, as shown in FIG.
The convex portion 21 of the other connecting member 12 attached to the end of the connecting member 12 is fitted, and the space formed by the fitting is filled with the sealing material 24.

FIG. 7 shows yet another embodiment. In this embodiment, one of the connection members 11 is provided with a recess 17 having an arcuate cross section, and the other connection member 12 is provided with a protrusion 21 with a round cross section. mounting part 15,
20 is configured to have a U-shaped cross section, and predetermined portions corresponding to the upper projection 4 and lower projection 5 of the inorganic eaves gutter 1 are cut out, which are the same as those in FIG. 1. .

In such a connecting device, as shown in FIG. 8, the space on both sides of the recess 17 that is created when the projection 21 is fitted into the recess 17 is filled with a sealing material 24.

[Effect of idea]

Since the connecting device of the present invention is constructed as described above, it is possible that the inorganic eaves gutters that are connected to each other may be misaligned, or that the inorganic eaves gutters may become misaligned over time after installation, or that the inorganic eaves gutters may absorb water. Even if the sealing material contracts, the required watertightness of the connection part is always maintained reliably by the sealant, and there is no risk of water leakage from the connection part. Furthermore, since the sealant is filled into the above-mentioned space, the sealant is prevented from protruding from between the two connecting members, resulting in a clean appearance and reducing the performance of the sealant. It has a waterproof effect for a long time without any damage. Further, since both of the pair of connecting members are compatible with injection molding of synthetic resin, there is an advantage that they can be manufactured with high precision and at low cost.
