DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter suspender for a folded plate roof which is fixedly attached to a folded plate roof and holds a gutter.

[0002]

2. Description of the Related Art Conventionally, there are various types of gutter hanging tools for folded-plate roofs. Installation of gutter hanging devices on folded-plate roofs or eaves gutters on gutter hanging devices, after installation, are sufficiently resistant to external forces and vibrations such as wind and snow, and gutter hanging devices are firmly attached. Is desirable.

A gutter hanging device described in Japanese Utility Model Laid-Open Publication No. 3-41024 is known as such a gutter hanging device for a folded-plate roof. The gutter hanging device described in Japanese Utility Model Laid-Open Publication No. 3-41024 has a threaded rod set up almost at the center of a gutter support having gutter ear holding portions at both ends, and a fixing hole is formed near the upper end. A horizontal piece protrudes below the band-shaped plate body, a vertical screw hole is formed in the horizontal piece, and the upper end of the screw rod is inserted and screwed into the screw hole.

In this gutter hanging device, a fixing hole is formed in the longitudinal direction substantially at the center of the gutter support, and the lower end of the threaded rod is inserted into the fixing hole and fastened with a nut. Move the screw rod in the fixing hole, adjust the length of the gutter hanging tool from the folded plate roof, tighten with nuts, fix the gutter support and the screw rod, and attach the gutter to the gutter support. Attach it.

[0005]

However, the gutter hanging device described in Japanese Utility Model Application Laid-Open No. 3-41024 is fastened only by tightening nuts.
Nuts are not tightened properly due to poor scaffolding and poor visibility, and after installation, nuts are gradually loosened due to external force or vibration such as wind and snow, and nuts come off. There was a problem.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a gutter hanging device which can be easily mounted on a folded-plate roof, and after installation, the nut is gradually loosened due to external force or vibration such as wind and snow, so that the nut does not come off. Is provided.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and the invention according to claim 1 is characterized in that a lower end of a suspension bolt and a gutter ear holding portion are provided at both ends. In a gutter hanging device for a folded plate roof in which a gutter supporting member having an insertion hole in the center is fixed by a nut, upper and lower nuts fixed to hanging bolts are notched in a substantially vertical direction in the center. A U-shaped loosening prevention member having a portion, which is sandwiched in a state where a suspension bolt is inserted into the notch.

The invention according to claim 2 is for a folded plate roof in which a gutter support having a gutter ear holding portion at both ends and an insertion hole at the center is fixed to a lower end portion of a suspension bolt by a nut. In the gutter hanging device of the above, the gutter support is provided with a stepped portion which is lowered one step adjacent to the insertion hole on one side in the short direction of the gutter support, and the step of the gutter support is provided between the nuts. And a slack preventing member having a central portion formed into an elliptical rod-like body, which is sandwiched with the longitudinal direction of the rod-like body being horizontal, so that the slack preventing member is rotatable.

The material of the gutter support, the suspension bolt, and the loosening prevention member in the present invention may be any suitable material such as a metal or a synthetic resin.
It is preferable because it is excellent in strength and rust prevention. In particular, it is preferable for the loosening prevention member to have spring elasticity, since the nut can be firmly pressed by the spring elasticity.

According to the first aspect of the present invention, the shape of the loosening prevention member is such that a notch is provided in a substantially central vertical direction, and upper and lower nuts are fitted into the U-shaped loosening prevention member. If it can be locked, it may be in an appropriate shape, for example,
If a vertical plate body facing upward is provided at the upper end of the U-shape of the loosening prevention member and a projecting portion is provided at the lower front end toward the inside, the vertical plate is brought into contact with the suspension bolt. By inserting the suspension bolt into the notch and inserting the upper and lower nuts into the loosening prevention member, the projecting portion at the lower end portion is hooked on the nut, and the loosening prevention member can be locked to the nut. Therefore, it is preferable.

In the second aspect of the present invention, the shape of the loosening prevention member may be an appropriate shape as long as the center portion is formed as an elliptical rod having a cam function and is rotatable.
For example, both ends of the anti-loosening member are small round bars, the central portion is an elliptical bar having a cam function, and the handle is upwardly directed to the small round bar at one end so as to be substantially orthogonal to the longitudinal side of the bar. If provided, by turning this handle to the left or right, the longitudinal direction of the elliptical rod becomes vertical, and the upper and lower nuts can be pressed in the longitudinal direction of the rod. preferable.

[0012]

According to a first aspect of the present invention, there is provided a U-shaped loosening prevention member having a cutout in a substantially central portion in a vertical direction. The cutout is fixed to the hanging bolt with the hanging bolt inserted into the cutout. Since the upper and lower nuts are sandwiched, insert the upper and lower nuts and gutter support into the suspension bolts, tighten the gutter support with the upper and lower nuts, and fit the upper and lower nuts into the loosening prevention member, The upper and lower nuts can be locked by the shape-preventing loosening members, so that the upper and lower nuts are not loosened even when external force or vibration such as wind and snow is applied to the upper and lower nuts.

According to a second aspect of the present invention, the gutter support is provided with a step which is lowered by one step adjacent to the insertion hole on one side in the short direction of the gutter support, and the gutter support is provided between the nuts. The step part of the tool and the loosening prevention member whose central part is made into an elliptical rod-like body,
Since the bar is sandwiched with the longitudinal direction in the horizontal direction and the loosening prevention member is made rotatable, insert the nut and gutter support into the suspension bolt, tighten the gutter support with the upper and lower nuts, and perform the cam function. By rotating the loosening prevention member having the upper and lower nuts, the longitudinal direction of the elliptical rod-shaped body becomes the vertical direction, and the upper and lower nuts can be pressed and locked in the longitudinal direction of the rod-shaped body, and the nut can be locked. Even if external force or vibration such as wind or snow is applied to the nut, the nut is not loosened.
