Description

  The present invention relates to a rain gutter mounting structure that is attached to a folded-plate roof of a building, and more particularly, to a rain gutter mounting structure that stabilizes a large gutter suspended from a folded-plate roof so that it does not shake during construction or strong winds.

  Conventionally, a structure using suspension means is known as a method of attaching a large rain gutter to a folded plate roof. Such a gutter mounting structure is disclosed in Patent Document 1, for example.

  As shown in FIG. 9, the gutter mounting structure 31 of Patent Document 1 fixes the upper end portion of the vertical member 2 with the hanging bracket 1 fixed to the lower end portion to the mountain portion 4 of the folded plate roof 3 and the hanging bracket 1. Is reinforced by a reinforcing diagonal member 5.

  The reinforcing diagonal member 5 is formed of a belt-like material, and an engaging portion 10 bent in a substantially U shape is formed at one end of the reinforcing diagonal member 5, and the engaging portion 10 is separated from the upper end portion of the vertical member 2. It fixes to the front-end edge of the peak part 4 of the folded-plate roof 3 with the thumbscrew 32 in the position.

  On the other end of the reinforcing diagonal member 5, a coupler 6 integrally formed of synthetic resin is pivotally attached to the side surface of the rear end portion of the reinforcing diagonal member 5 via a shaft pin 33. The coupler 6 includes a recess 7 having a side opening 8 penetrating vertically and opening to the side, and the recess 7 is fitted from the side opening 8 to the middle portion of the vertical member 2.

  When the vertical member 2 is inserted from the side opening 8, the side opening 8 expands against the elasticity of the coupler 6, and when the vertical member 2 is fitted in the recess 7, The opening 8 is contracted by an elastic restoring force. For this reason, in a state where the vertical member 2 is fitted in the concave portion 7, the outer peripheral surface on which the male screw 9 of the vertical member 2 is formed is engaged with the inner peripheral surface of the concave portion 7.

  Thus, since the reinforcing diagonal member 5 is constructed and fixed between the middle portion of the vertical member 2 and the position of the folded plate roof 3 away from the upper end portion of the vertical member 2, the vertical member 2 is substantially the same. It becomes vertical and can prevent shake reliably.

Since a concave portion 7 is formed in the joint 6 of the reinforcing diagonal member 5 so as to penetrate vertically and open to the side, the concave portion 7 is fitted to the vertical member 2 from the lateral opening 8 during construction. The material 5 can be easily attached. Moreover, since the engaging part 10 bent in a substantially U shape is formed at one end of the reinforcing diagonal member 5, the engaging part 10 can be easily engaged with the tip edge of the peak part 4 of the folded plate roof 3. And it can be reliably coupled and fixed.

<Configuration of rain gutter mounting structure>
Below, the 1st Embodiment of this invention is described based on FIGS.

  As shown in FIGS. 1 and 2, the gutter mounting structure 11 of the present invention is a gutter mounting structure that is suspended by a hanging means 15 from a mountain portion 14 a of a folded plate roof 14 via a hanging bracket 13 of the gutter 12. It is.

  Here, the rain gutter 12 has a concave cross-sectional shape, and is provided with a concave ear portion 12a as an outdoor side gutter suspension portion and a convex ear portion 12b as an indoor side gutter suspension portion at the upper end. The hanging bracket 13 has a central portion 13c that is substantially horizontal and protrudes from both ends, and hook-like ear holding portions 13a and ear holding portions 13b are formed at both ends. The rain gutter 12 is suspended from the folded plate roof 14 by the suspending means 15 with the ears 12a and the ears 12b held by the ear holding part 13a and the ear holding part 13b of the hanging bracket 13, respectively.

  The suspending means 15 is composed of a vertical member 16 and a reinforcing diagonal member 17, and the vertical member 16 is an all-threaded round bar having a diameter R = 9.525 mm (wit screw W3 / 8) and formed at the upper end 16a and the lower end 16b. The male screw portion 16 c penetrates the peak portion 14 a and the central portion 13 c of the hanging metal fitting 13, and is fixed to the mountain portion 14 a and the hanging metal fitting 13 with a pair of nuts 18, respectively.

  Here, a packing 19 for preventing leakage of rainwater from the through hole 14c through which the vertical member 16 penetrates the peak portion 14a and absorbing vibration is inserted outside the peak portion 14a.

  The reinforcing diagonal member 17 is formed of a strip plate having a thickness of 2 mm. The horizontal portion 17b provided on the upper end portion 17a of the oblique main member 17e is connected to the oblique main member 17e of the reinforcing oblique member 17 at one end 17c along the mountain portion 14a at a position away from the upper end portion 16a of the vertical member 16. The other end 17d extends from the upper end portion 16a of the vertical member 17 to a position away from the one end 17c in the opposite direction.

  And the hole 20 provided in the horizontal part 17b is formed in a U-shaped hole so that the vertical material 16 can be inserted from the side surface 17h of the horizontal part 17b. The horizontal portion 17 b is fixed to the peak portion 14 a together with the vertical member 16 through the hole 20.

  Two sets of holding portions 21 that hold the lower portion of the vertical member 16 as much as possible are provided in a short cylindrical shape surrounding the vertical member 16 on the vertical portion 17g connected to the lower end portion 17f of the oblique main member 17e.

  As shown in FIGS. 3, 4, 5, and 6, the shape of the reinforcing diagonal member 17 is formed such that the horizontal portion 17b has a length L1 = 94 mm and the vertical portion 17g has a length H1 = 42 mm. The vertical interval between the horizontal portion 17b and the vertical portion 17g is H2 = 78 mm, the length L2 from the other end 17d of the horizontal portion 17b to the center of the hole 20 is L2 = 25 mm, and the distance from the one end 17c to the center of the hole 20 Length L3 = 69 mm.

  Thereby, the oblique main member 17e is formed at an angle β = approximately 40 degrees with respect to the vertical portion 17g. The hole 20 has a U-shape formed by connecting a semicircle with a radius R2 = 5 mm provided at the center of the horizontal portion 17b and a line having a width R1 = 10 mm perpendicularly from the side surface 17h to the side surface 17h. The width of the band-shaped reinforcing diagonal member 17 including the horizontal portion 17b is formed with the same width S = 25 mm as the inner method of the peak portion 14a.

  The holding part 21 includes an arc part 22 and a base 23 for fixing the arc part. The circular arc part 22 of the holding part 21 has a short cylindrical shape with a height T1 = 14 mm, and is formed in two sets by cutting out a substantially 1/4 circular arc region of the entire circumference, and is continuously formed integrally with the base 23 in between. Is done. The total length T in the vertical direction is 40 mm.

  The cross-sectional shape of the arc portion 22 is an arc having an inner radius G1, and an opening portion 21c is provided with a receiving width G2. The opening portion 21c further includes a small arc-shaped receiving guide portion 21d that curls outward.

  Here, the arc portion 22 is formed with an inner radius G1 = 3.9 mm with respect to the center Q1, and therefore, when the vertical member 16 having a diameter R = 9.525 mm is inserted, (G1 × 2) <R. Therefore, the vertical member 16 can be reliably and stably held. The center Q1 is disposed so as to be located on the perpendicular bisector of the base 23.

The receiving width G2 = 5.9 mm of the receiving guide portion 21d is smaller than the diameter R = 9.522 mm of the vertical member 16 in order to hold the vertical member 16 so as not to be detached, and is formed in a relationship of G2 <R. In addition, since the width G3 = 8.4 mm of the receiving guide portion 21d is formed wider than the receiving width G2, the vertical member 16 can be easily addressed and guided. (G3> G2)
The base 23 has a width S1 = 20 mm and a vertical length T2 = 10 mm, and is provided with a gap of T3≈1 mm with respect to the upper and lower arc portions 22. The base 23 is provided with two sets of mounting holes Q2, and is fixed to the vertical portion 17g with a screw or the like (not shown).

  Since the material of the suspending means 15 and the hanging metal fitting 13 requires strength, stainless steel, galvanized metal, or the like is used.

<Operation of rain gutter mounting structure>
As described above, even when a force swaying in the lateral direction of the rain gutter works, either one end 17c or the other end 17d, which is both ends of the horizontal portion 17b of the reinforcing diagonal member 17, abuts the folded plate roof 14, The suspension means 15 is in a state of being substantially supported by the folded plate roof 14 at two points. For this reason, the suspending means 15 is reliably stable because it is less likely to sway and deform even during construction or during strong winds with respect to the lateral direction of the rain gutter. In addition, since the structure is simple, the cost can be reduced.

  Since the hole 20 of the horizontal portion 17b is a U-shaped hole, it can be easily inserted into the vertical member 16 from the side surface 17h of the horizontal portion 17b by retrofitting, and the work process is flexible, so that workability is improved.

  Since the holding portion 21 is formed by cutting out a substantially ¼ arc region of the entire circumference of the short cylindrical shape, it is not necessary to insert the holding portion 21 into the vertical member 16 in advance. Since the holding portion 21 can be attached even after being attached to 14, the convenience of attachment is excellent, and the work process is flexible, so that workability is improved.

  Since the width of the horizontal portion 17b of the reinforcing diagonal member 17 is formed with the same width S = 25 mm as the inner method of the peak portion 14a, the horizontal portion 17b of the reinforcing diagonal member 17 can be simply slid along the inner method of the peak portion 14a. Since the horizontal portion 17b can be adjusted to the mounting position, the mounting operation can be facilitated. Moreover, since it is hold | maintained by the internal method of the peak part 14a so that there may be no backlash, the suspension means 15 with respect to the vertical direction of the gutter 12 can be prevented from shaking.

  In this way, since the suspension means 15 can be manufactured with a simple structure, the cost can be reduced, and it is easy to install, and the shaking of the rain gutter in the lateral direction can be reliably prevented, so that it is difficult to shake even during construction or during strong winds. Deformation can be prevented.

<Second Embodiment of the Present Invention>

  As shown in FIGS. 7 and 8, the holding portion 21a is a short cylindrical portion 22a having an inner diameter G = approximately 10 mm and a total length T = 40 mm surrounding the vertical member 16, and a base 23a for fixing the short cylindrical portion 22a is provided. Prepare.

  If it is this shape, since the holding | maintenance part 21a will certainly increase intensity | strength compared with 1st embodiment formed by notching the substantially 1/4 circular arc area | region of a short cylinder-shaped perimeter, the suspension means 15 is further provided. It can be fixed stably. In this case, before attaching the vertical member 16 to the folded plate roof 14, the holding portion 21 a needs to be fitted in the vertical member 16 in advance.

  As mentioned above, although embodiment of this invention was described based on drawing, all said Example shows an example of this invention, and it cannot be overemphasized that this invention should not be limited to these.

  For example, the holding part 21 may be a set of holding parts 21 instead of providing two sets of upper and lower parts. In this case, it is preferable to make the height of the holding portion 21 a little higher because the holding force can be compensated. The hole 20 of the horizontal portion 17b may be a circular hole provided at the center of the horizontal portion 17b instead of the U-shaped hole. Moreover, the same structure as the said Example can be implemented also with respect to the rain gutter and hanging bracket which have other various cross-sectional shapes.
