Description

[Detailed description of the invention] [Field of industrial application] This invention is a joint structure of an inorganic rain gutter manufactured by molding foamed concrete, cement material mixed with inorganic fibers, or other inorganic material. Regarding.

[Conventional technology]

Although commonly used rain gutters are constructed from synthetic resin molded products, the applicant has devised an inorganic rain gutter made from cement-based materials mixed with foamed concrete or inorganic fibers. This inorganic rain gutter is nonflammable, so it is useful in promoting fireproofing measures for buildings.Moreover, it has high strength and does not deteriorate due to ultraviolet rays, industrial smoke, or low temperatures, so it is weather resistant and frost resistant. It has various advantages such as excellent durability and stretch resistance. In addition, its material properties make it a heavy and elegant rain gutter, so it should be prized as a rain gutter for modern buildings, especially concrete buildings.

Such inorganic rain gutters can be installed by directly attaching the wall to roofing materials such as eaves fascias with screw screws, or by supporting them from below with gutter holders attached to the fascia, etc. However, if the length of the inorganic rain gutter is insufficient, additional legs will be installed as necessary.

[Problem that the invention attempts to solve]

However, although inorganic rain gutters have the various advantages mentioned above, they are quite heavy, so when the joints are constructed, they tend to create gaps or steps at the joints.

In other words, in order to reduce the weight of inorganic rain gutters,
Although a plurality of longitudinally extending hollow portions partitioned by ribs are formed in the inorganic layer forming the outer wall consisting of the bottom wall, the front wall, and the rear wall, the Because of the heavy weight of the inorganic rain gutter, it is difficult to manually support the inorganic rain gutter when constructing the joints and adjust the joints so that there are no gaps or differences in level. There were many cases where there was a difference in level.

The present invention solves the above problems, and provides a joint structure that effectively utilizes the hollow part provided in the inorganic layer that forms the outer wall of the inorganic rain gutter to reduce its weight. In order to solve the above problems, this book aims to prevent gaps and steps from forming at the joints of inorganic rain gutters that have been constructed with joints.[Means to solve the problem] The joint structure of the invention is that one end of the rod-shaped connecting body is fitted into the hollow part of one of the inorganic rain gutters that are butted against each other, and this connection is inserted into the hollow part of the other inorganic rain gutter. The gist is that the other end of the body is fitted and a sealing material is loaded between both inorganic rain gutters.

[Effect]

According to the joint structure of the above configuration, the inorganic rain gutters are positioned relative to each other by the connecting body fitted into the respective hollow parts of the inorganic rain gutters that are butted against each other, and both inorganic rain gutters are The gaps between the two are filled with a sealant.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view showing an inorganic rain gutter A and a connector B having a rod-shaped connector 1. As shown in FIG. The inorganic rain gutter A (hereinafter referred to as the rain gutter) shown in the same figure is composed of a molded product made from cement-based material mixed with foamed concrete or inorganic fibers. This rain gutter A integrally has an engaging portion 3 projecting outward from the rain gutter A at the upper end of the rear wall 2, and a part of the rear wall 2 has a thick wall portion that is thicker than other parts. 21. Furthermore, the bottom wall 4 extends rearward, and a protruding strip 42 is formed at the end of the extending portion 41. On the other hand, the front wall 5 is separate from the integral body of the rear wall 2 and the bottom wall 4, and the front wall 5 is attached to a rising portion 43 formed at the front end of the bottom wall 4 via an adhesive. It is configured to be joined. The rain gutter A has a groove formed by the rear wall 2, the bottom wall 4, and the rising part 43, and rainwater flows down the groove, so the front wall 5
It will also function as a decorative plate.

In such a rain gutter A, a plurality of hollow portions 71 partitioned by ribs 7 are formed in the inorganic layer forming the rear wall 2 and the bottom wall 4. Further, a plurality of hollow portions 71 similarly partitioned by ribs 7 are formed within the inorganic layer forming the front wall 5. By forming the hollow part 71 in this way, the rear wall 2 and the bottom wall 4 are integrated, and the front wall 5
Despite the weight reduction achieved, its strength itself is comparable to that of a solid material.

Figure 2 shows the rain gutter A installed at the eaves. As is clear from the figure, the engaging portion 3 formed on the rear wall 2 is suspended from a mounting bracket 110 fixed to a plate-shaped support member 100 provided at the eave by an appropriate means such as nailing. At the same time, the thick part 21 of the rear wall 2 is connected to the support member 10.
0, and is fixed by screw screws 130, and furthermore, the protrusion 42 of the extending portion 41 is in contact with the lower surface of the eave ceiling 120. As a result, the gap between the support member 100 and the soffit 120 is covered by the rear wall 2, so a fascia that is normally provided to close the gap between the eaves and the soffit 120 is provided on the rear wall 2. It is also used for both purposes. However, it is of course possible to provide the support member 100 with a fascia. Further, the front wall 5 is joined to the rising portion 43 of the bottom wall 4 via an adhesive. In addition,
The rising portion 43 has a stepped portion 44 at its upper end, and an engaging portion 51 formed on the back surface of the front wall 5 is connected to the stepped portion 4.
4 prevents the front wall 5 from falling forward.

Next, the connector B shown in FIG. The above-described connecting body 1 is provided so as to protrude to both sides of the partition plate 8. The connecting body 1 has a thickness that allows it to be inserted into the hollow portion 71 without play. In such a connector B, the connector 1 does not necessarily have to be provided corresponding to all the hollow parts 71 of the bottom wall 4, the rear wall 2, and the front wall 5. It is sufficient to provide corresponding portions 71.

Figure 3 shows rain gutter A, which is connected by connecting device B.
This shows the state in which A′ is added. As shown in the figure, one end 11 of the connecting body 1 of the connecting tool B is fitted into the hollow part 71 of one of the rain gutters A and A' that are butted against each other, and the other end 11 of the connecting body 1 of the connecting tool B is inserted The other end 12 of the connecting body 1 is fitted into the hollow portion 71'. A silicone or urethane sealant is filled between the rain gutters A and A' to prevent water from leaking.

When rain gutters A and A' are connected in this way, both rain gutters A and A' are mutually positioned by the connecting body 1 of the connector B, so these rain gutters A,
As long as the thickness of the outer wall of A' is the same, there will be no step at the joint. Furthermore, the gap between the joints is filled with the sealant 9, so
No water leaks from the joints. In addition, the above-mentioned connector B has a front wall 5 attached to one partition plate 8.
Since the connecting body 1 fitted into the hollow part 71 and the connecting body 1 fitted into the hollow parts 71 of the bottom wall 4 and the rear wall 2 are provided, the front wall 5 is a separate rain gutter. A has the advantage that the front wall 5 is firmly assembled to the bottom wall 4 and the rear wall 2 by the connector B. Furthermore, if a plate body 81 is provided on the lower edge of the partition plate 8 like the connector B shown in FIG.
As shown in FIG. 3, when the sealant 9 is loaded between the rain gutters A and A', the sealant 9 is received by the plate 81, so there is an advantage that the sealant 9 does not flow down.

FIG. 4a shows a modification of the connector B described in FIG. 1. This connector B omits the part corresponding to the front wall 5 of the rain gutter A and the part corresponding to the plate 81 from the partition plate 8 in the connector B explained in FIG. Portion 8 corresponding to bottom wall 4
The vertical width of 2 is the same as the thickness of the connecting body 1, and further,
The front surface of the connecting body 1 provided on a portion 83 corresponding to the rear wall 2 of the rain gutter A is flush with the front end surface of the portion 83, and further provided on the portion 84 corresponding to the extension portion 41 of the rain gutter A. The lower surface of the connecting body 1 that is
It is flush with the lower end surface of 4. In addition, the fourth
Since the rain gutter A shown in Fig. a is similar to the rain gutter A described in Fig. 1, corresponding parts are given the same reference numerals and detailed explanations are omitted.

When a rain gutter is connected using such a connector B, the connector 1 is covered and hidden by the sealant 9 loaded into the gap between the bottom walls 4 and 4', as shown in Fig. 4b. becomes invisible. Further, a sealing material 9 is similarly filled in the gap between the rear walls 2 and 2', so that the connecting body 1 is no longer visible from the outside. Therefore,
By making the sealing material 9 the same color as the rain gutters A and A' (for example, the color of cement), there is an advantage that the connecting parts of the rain gutters A and A' become less noticeable. Further, since the gap for loading the sealing material 9 is widened, it can be loaded reliably and has the advantage of preventing water leakage. Other points are the same as those explained in FIG. 3.

FIG. 5 shows another modification of the connector B.
This connector B is provided with a collar 10 at a location slightly deviated to one side from the center of the rod-shaped connector 1. When connecting rain gutters using such a connector B, one end 11 of the connector 1 is inserted into the hollow part of one of the rain gutters that are abutted against each other, and What is necessary is just to fit the other end part 12 of the connecting body 1 into the hollow part, and to load the sealing material between both rain gutters. Furthermore, according to the connector B shown in FIG. 5, it is possible to connect rain gutters that are butted together at a predetermined interval without moving them. That is,
In that case, as shown in Fig. 6a, insert the long end 12 of the connecting body 1 in the connecting tool B into the hollow part 71 of one rain gutter A until the collar 10 touches the end surface of that rain gutter A. Place the short end 11 opposite the hollow part 71' of the other rain gutter A', then pull out the connecting body 1 from one rain gutter A and connect the short end 11 to the other rain gutter A'. 6b into the hollow part 71', and then the 6b
As shown in the figure, sealant 9 is loaded between both rain gutters A and A'. Even with the joint structure shown in FIG. 6b, no gaps or steps are created at the joint.

In the above explanation, the connector B shown in FIGS. 1 and 4a is provided with the number of connectors 1 necessary for adding rain gutters to M partition plates, and simultaneously connects these connectors 1 to the hollow of the rain gutter A. The connecting tool B in FIG. 5 has one connecting body 1,
This connecting body 1 is individually fitted into a plurality of hollow parts 71 of the rain gutter A, but in addition to these, there are also a plurality of connecting devices in which a plurality of connecting bodies are provided on one small piece of partition plate. Of course, it is also possible to connect the rain gutters by interposing them between individual rain gutters, or to make one end 11 of the connector B in FIGS. 1 and 4a longer than the other end 12. Furthermore, if the connecting body 1 is provided with a taper, it can be easily inserted into the hollow portion 71.

[Effect of idea]

As explained above, when the joint structure of the present invention is adopted, even if the rain gutter is relatively heavy because it is made of inorganic material, the hollow space in the inorganic layer forming the outer wall By making effective use of the sections, it becomes possible to connect rain gutters to each other with good workability without creating gaps or differences in level. Also,
Construction is economical because it only requires the use of a rod-shaped connecting body and sealant.
