Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to the mounting structure of an inorganic rain gutter manufactured by molding foamed concrete, cement material mixed with inorganic fibers, or other inorganic material. .

[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 for promoting fireproofing measures for buildings.Moreover, it has high strength and does not deteriorate due to ultraviolet rays, industrial smoke, or temperature, 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.

As the above-mentioned mounting structure for inorganic rain gutters, the present applicant fixed the mounting hardware to multiple locations on the roofing material, such as the fascia of the eaves, so that the rain gutter receiving brackets could not be seen from the front, and these We considered fitting bolts protruding from the mounting bracket into holes made at multiple locations on the back wall of the inorganic rain gutter, and then tightening nuts onto the bolts.

[Problem that the invention attempts to solve]

However, although inorganic rain gutters have the various advantages mentioned above, they also have a considerable weight and are almost impossible to deform elastically. Not only is it not easy to properly fit the bolts into the mounting bracket bolts, but when installing multiple inorganic rain gutters together, it is easy to create a step at the joint, and if a step occurs, it is necessary to correct it. The problem was that it wasn't easy.

This invention solves these problems and improves the workability of arranging and fixing the gutter during construction, and when performing joint construction, it is possible to perform construction without creating a step at the joint. The purpose of the present invention is to provide a structure for attaching an inorganic rain gutter that can be easily installed.

[Means for solving problems]

In order to solve the above problems, the mounting part structure of the present invention is such that the upper end of the rear wall of the inorganic rain gutter, in which the front wall is separate from the bottom wall and the rear wall, is suspended from a mounting bracket fixed to the eaves. The main feature is that the rear wall is fixed at a proper position to a support member provided at the eaves by a fixing means.

[Effect]

The inorganic rain gutter installed with the above configuration is
The front wall can be fixed at the appropriate place on the back wall with the fixing means by hanging the bottom wall and the back wall, which are separate from the front wall, from the mounting bracket fixed to the eaves. Fixing work can be done easily without getting in the way. Then, by joining the front wall after fixing, an inorganic rain gutter is constructed, and the rain gutter receiving metal fittings are not visible from the front. In addition, when constructing joints, if the back wall is fixed to the support member with the adjacent bottom wall and rear wall suspended from the same mounting bracket, the joints of the inorganic rain gutter after construction can be fixed. There are no steps in the area.

〔Example〕

Hereinafter, a mounting structure according to an embodiment of the present invention will be described.

In FIGS. 1 and 2, the rain gutter A is composed of an inorganic molded product made from cement material mixed with inorganic fibers, and its front wall 6 is connected to the bottom wall 4 and rear wall 1. It is separate from the integral body, and the front wall 6 is joined to a rising portion 43 formed at the front end of the bottom wall 4 via an adhesive. The height of the rising portion 43 is set lower than the thick portion 12 of the rear wall 1, which will be described later. Also, the rising part 4
A stepped portion 44 is provided at the upper end of the front wall 6, and the engaging portion 61 formed on the back surface of the front wall 6 is engaged with the stepped portion 44 to join the two, which increases the joining area. This not only increases the strength of the joint, but also prevents the front wall 6 from falling forward. If the front wall 6 is made separate in this way, it is convenient that the eaves gutter can be redesigned by replacing only the front wall 6, which serves as a decorative board. Furthermore, the work of hanging the rain gutter from the mounting bracket requires only the integral part of the bottom wall and the rear wall, and the weight of the inorganic rain gutter can be dispersed, making the work of hanging and joining easier. On the other hand, an engaging portion 2 projecting outward from the inorganic rain gutter A is integrally provided at the upper end of the rear wall 1. In addition, if the inorganic rain gutter A is formed with a large number of hollow parts 71 partitioned by ribs 7 as shown in the figure, weight reduction can be achieved without significantly reducing the strength. Such an inorganic rain gutter A is constructed by attaching the engaging portion 2 to an engaging piece 111 of a mounting bracket 110 that is fixed to a plate-shaped support member 100 provided perpendicularly to the eaves by appropriate means such as nailing or screwing. By fitting into the recess 21 of the inorganic rain gutter A, the rear wall 1 of the inorganic rain gutter A is suspended from the mounting bracket 110 and prevented from falling. Further, a part of the rear wall 1 is thicker than other parts, and the thick part 12 is in contact with the support member 100 at the lower part of the mounting bracket 110. It is fixed by a fixing means 3 such as a screw screw. Furthermore, the bottom wall 4 of the inorganic rain gutter A extends rearward, and a protruding strip 42 provided at the end of the extending portion 41 extends to the eave ceiling 1.
It is in contact with the lower surface of 20. Note that 5 is a washer interposed between the head 31 of the fixing means 3 and the rear wall 1.

In the above mounting structure, since the rear wall 1 is suspended by the mounting bracket 110 and a part of the weight of the inorganic rain gutter A is supported, it is necessary to support the entire weight of the rain gutter A by the fixing means 3. There is no. Therefore,
There is no need to use a very strong fixing means 3. Further, since the rear wall 1 is suspended from the mounting bracket 110 and is fixed to the support member 100 by the fixing means 3 with the thick part 12 of the rear wall 1 in contact with the support member 100, The fluttering of the rain gutter A due to wind pressure etc. is reliably prevented. moreover,
Even if a gap S is left between the support member 100 and the eaves 120 as shown in the figure, there is no risk that this gap S will be covered by the rear wall 1 and the extension 41 and rain will blow in. It disappears. Therefore, there is an advantage that the rear wall 1 can also be used as a fascia, which is normally provided to close the gap between the eaves and the ceiling of the eaves. However, it is of course also possible to use a fascia as the support member 100. In addition, since the bottom wall 4 extends rearward and the protruding strip 42 provided at the end of the extending portion 41 is brought into contact with the lower surface of the eave ceiling 120, there is a gap between the inorganic rain gutter A and the eave ceiling 120. Another advantage is that there are no gaps between the roof and the eaves, making the eaves clear and clean when viewed from below.

Next, an example of the construction procedure for the inorganic rain gutter A installed as described above will be explained.

First, short mounting fittings 110 are fixed at appropriate positions on the support member 100 at intervals. At this time, it goes without saying that the flow gradient of rainwater to be applied to the inorganic rain gutter A should be taken into consideration. Note that the mounting bracket 110 is not limited to the above-mentioned short one, but may be a long one. Next, attach the engaging part 2 of the inorganic rain gutter A, which is an integrated body consisting of the bottom wall 4 excluding the front wall and the rear wall 1, to the mounting bracket 1.
10 to suspend the rear wall 1 from the mounting bracket 110, and the thick portion 12 of the rear wall 1 is brought into contact with the support member 100. When installing inorganic rain gutter A,
In this state, adjust the joint parts of the integrated body so that there are no steps, and then insert the fixing means 3, for example screw screws, from multiple places on the rear wall 1 into the thick part 12.
is driven into the support member 100 to fix the rear wall 1 at a predetermined location. At this time, the suspended integral object does not have the front wall 6, and the rising part 43
Since this is lower than the thick portion 12, the screw screw can be driven in easily without being obstructed by the front wall 6 or the rising portion 43. Thereafter, the front wall 6 is joined to the rising portion 43, and the inorganic rain gutter A is attached to the eaves. In addition, when constructing the joints of the above-mentioned inorganic rain gutter A, the engaging parts 2, 2 of the rear wall 1 of the left and right integral parts at the joints are connected to one mounting bracket 110.
This is advantageous because the difference in level between the joints is naturally eliminated and no adjustment is required. Therefore, it is no longer necessary to manually support the integrated object and adjust it so that there are no steps at the joints, improving work efficiency and ensuring reliable work.
Furthermore, as shown in FIG. 2, if a line A such as a convex strip or a groove is inserted into the inner surface of the rear wall 1 and the driving level of the fixing means 3 is indicated by this line A, then this line A can be used to indicate the driving level of the fixing means 3. As a guide, it becomes possible to easily drive the fixing means 3 into an appropriate location.

FIG. 3 shows a mounting bracket 110 formed with a recess 13 on the back surface of the upper end of the rear wall 1 and fixed to the support member 100.
This figure shows an inorganic rain gutter A in which the rear wall 1 is suspended from a mounting fitting 110 by inserting the recessed part 13 into the protruding piece 112 of the figure. The points that the rear wall 1 is fixed to the support member 100 by fixing means 3 such as screw screws, and that the thick part 12 provided in a part of the rear wall 1 is in contact with the support member 100 are shown in FIG. and the same as described in FIG.

In the mounting structure shown in FIG. 4, an engaging portion 8 that protrudes forward is integrally provided at the upper end of the rear wall 1, and an engaging piece 111 of a mounting bracket 110 fixed to an eaves member 130 such as a roofing board at the eaves. engaging the engaging portion 8, and
A rear wall 1 is fixed to a support member 100 using fixing means 3 such as screw screws.

The mounting structure shown in FIGS. 3 and 4 also provides the same effect as that explained in FIGS. 1 and 2. Therefore, in FIGS. 3 and 4,
The same parts as those described in FIG. 1 and FIG. 2 are given the same reference numerals, and detailed description thereof will be omitted.

FIG. 5 shows another embodiment of the present invention, in which an engaging part 2 protrudes outward from the upper end of the rear wall 1 of the inorganic rain gutter A, and the bottom wall 4 extends rearward and further downward. The fixing part 15 is formed by the fixing part 15. In this example,
A mounting bracket 110 is fixed to the fascia, which is the support member 100, and the engaging part 2 of the inorganic rain gutter A is inserted into the mounting bracket 110 to suspend the rain gutter A.
is fixed to the fascia using fixing means 3 such as screw screws. Note that instead of fixing the fixing portion 15 directly, it may be fixed using another fixing tool 16 made of metal or the like, as shown by the imaginary line. Further, the same parts as those in FIG. 1 are given the same reference numerals and detailed explanations will be omitted.

[Effect of idea]

As explained above, according to the mounting part structure of the present invention, during construction, it is only necessary to hang the integral body consisting of the bottom wall and rear wall without joining the front wall to the mounting bracket, and it is possible to Work on rain gutters can be done easily, and joining work on front walls can be done similarly, improving workability. In addition, in the case of joint construction, it is possible to install the joint without creating a step between the bottom wall and the rear wall by simply hanging it from the mounting bracket, making it easy to install the joint without a step. It has great practical effects.
