Abstract

PURPOSE:To enhance the efficiency of snow-melting work by arranging snow- melting hot-water circulation pipes closely connected to each of structural members. CONSTITUTION:Membrane members 3 are arranged to the peripheral surfaces of structural members 2 arranged in the shape of a dome to form a dome structure 1. After that, each of the structural members 2 is formed in a pipe-like frame and, at the same time, hot water circulation pipes 4 arranged on the plane of the structure approximate by in the shape of a grating and closely connected to the structural members 2 are respectively laid. Then, hot-water is circulated in the pipes 4 by force, and a rising warmth layer moving in the direction of the arrow is established to melt snow. Warmth is concentrated to the top of the dome where snow is apt to pile up to melt the snow efficiently by the rising warmth layer.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a snow melting structure in a dome structure that can efficiently melt accumulated snow.

(Problems to be solved by conventional technology and invention) In recent years, a frame membrane structure in which a membrane material is arranged around the outer periphery of a dome-shaped structural member has been adopted as one of the structural methods for large-span structures. dome structures are becoming popular.

In structures with frame membrane structures, the membrane material first bears the burden of snow loads and wind loads, and the stress is transmitted to each structural member. There was a problem in that the span of the material could not be set very carefully, and the inherent structural rationality of the membrane structure could not be fully demonstrated.

Therefore, in order to prevent this problem, there is a method of installing a heating device or the like, but since the volume of the structure itself is large, the burden of equipment and operating costs is high.

An object of the present invention is to solve the above-described conventional problems and provide a snow melting structure for a dome structure that can efficiently melt snow.

(Means for Solving the Problems) In order to achieve the above object, the present invention melts snow by arranging hot water circulating vibrators for snow melting in close contact with each structural member of a dome structure. This is a characteristic feature.

(Example) Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, and shows a dome structure as a construction with a frame membrane structure according to the embodiment.
A membrane material 3 is arranged around the outer periphery of a structural member 2 arranged in a dome shape.

In this embodiment, each structural member 2 is formed of a vibrator-like frame, and is arranged in a substantially grid-like manner on the plane of the dome structure 1.

In this embodiment, each hot water circulation vibrator 4 is disposed in close contact with each structural member 2 disposed in a direction perpendicular to the drawing in FIG. 1.

In addition, in the figure, 5 is a connecting structure member disposed on the top of the dome structure l, 6 is a lower structure disposed along the outer peripheral edge of the membrane material 3, and 7 is the upper end of the lower structure 6. This rain gutter is disposed corresponding to the melt water guide portion 8 formed to protrude outward from the rain gutter.

In this embodiment having the above configuration, each hot water circulation vibrator 4 is piped in close contact with the structural member 2, and by forcibly circulating hot water in each hot water circulation vibrator 4, it is possible to move the hot water in the direction of the arrow in FIG. A moving rising warm air layer is formed, and this warm air layer enables effective snow melting.

At this time, since there is a heat transfer effect from each hot water circulation vibrator 4 to the structural member 2 in close contact with it, snow can be melted evenly.

Furthermore, the rising warm air layer causes warm air to concentrate at the top of the dome where snow tends to accumulate, making it possible to efficiently melt snow.

Furthermore, since the structure forms a warm air layer only near the bottom surface of the membrane material 3 necessary for snow melting, it has a higher energy saving effect and lower operating costs than a method that heats the entire inside of the dome structure. .

Furthermore, since the warm air layer blocks cold heat from entering from the outside, energy-saving heating is possible in this respect as well.

Further, since snow can be melted immediately when snow falls, melted snow water can be collected from the rain gutter 7 in a clean form and can be reused.

Next, FIG. 2 shows a second embodiment of the present invention. In this embodiment, structural members 2 are arranged on the plane of the dome structure 1 in a radial direction centered on the top of the dome. , each hot water circulation vibrator 4 is disposed in a direction substantially orthogonal to the valley structural member 2, and each hot water circulation vibrator 4 is connected to each structural member 2 that intersects with it.

This embodiment also has the same effects as those of the above embodiment.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications may be made without departing from the gist of the present invention, such as the arrangement of the structural members 2, etc., being able to adopt other suitable device modes. Examples are possible.

(Effects of the Invention) The present invention is constructed as described above, and by arranging hot water circulation vibrators for snow melting in close contact with each structural member,
It is possible to melt snow efficiently and in an energy-saving manner.
