Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an improvement that makes it possible to eliminate the obstruction of structural functions and poor lighting caused by snow in areas with heavy snowfall in buildings with membrane roofs. It concerns structural roofs.

In general, membrane structure roofs are unsupported, can economically form large span spaces, and allow outside light to pass through the roof surface to capture daylight to a certain extent. (A), providing a comfortable space for people.However, in areas with heavy snowfall, overload or uneven load may occur on the roof due to snow, which may impede its structural function. In some cases, you may end up in a state where you lose all daylight.

The object of the present invention is to enable a membrane structure roof to function reliably in snowy regions as well as non-snowy seasons, and to completely eliminate poor lighting caused by snowfall.

The structure of the present invention is that //1 part of the film has light transmittance and heat resistance.
It consists of an upper membrane and a lower membrane 9, and a heating wire sealed in a heat-resistant tube is interposed between the upper and lower membranes. In Snowfall Lr.9, snow is removed by generating heat on the roof surface using heating wires to melt the snow, and during the snowfall season, Lr
i It generates heat in advance to prevent snow accumulation to a minimum, and when it snows quickly, complete snow removal is possible by using all auxiliary snow removal.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The external membrane constituting the membrane roof is a mat-like membrane with predetermined dimensions.
! It is formed by using a large number of films, and as shown in FIG. The upper membrane is made of a semi-transparent weather-resistant membrane material, and as this weather-resistant membrane material, Teflon (trade name) coated glass fiber cloth or the like is used. The lower film 3 is made of a more transparent and heat-resistant film material. Between the upper membrane 2 and the lower membrane 3, there is a pneumatic heating line 4 as shown in Figure 2.3.
A heat-resistant silicone tube 5 having a flat cross section, which is sealed inside, is interposed, and the upper and lower membranes and the tube are bonded to each other. This tube is arranged in a meandering and looped manner on the lower membrane 3, leaving a width at the periphery where it is bonded to the upper membrane 2. The tube 5 has a flat cross section,
An internal gap 6.6 is provided on both sides of the heat generation m4 to prevent the adhesion between the two upper membranes 2.3 from peeling off due to air expansion around the tube during heat generation.

Connection ends 7 and 7a are attached to both ends of the heating wire 40.
At the end, this ±-÷ square is made to protrude from the lower blade of the lower membrane 3.

Here, the mounting structure of the outer membrane 1 will be explained with reference to FIGS. 4 and 5.

The outer periphery of the outer membrane 1 is wrapped around the roof cable 8 once.

The couple with the external membrane wrapped around it is held between a pipe 10 placed around the roof via a 541 plastic resin member 9 and an aluminum frame 11 built along the couple. It is fixed to the pipe by.

With the above configuration, when it snows, the connection end 7.
The heating wire 4 is energized through the wire 7a to generate heat in the membrane 1, melting snow, and removing snow. During the fall season, heat is generated in advance to limit snow accumulation. In the event of heavy snowfall, 4m snow removal is also used to completely remove snow.

In order to prevent the heat generated by the heating wires 4 from propagating into the large inner space and wasting the amount of heat needed to melt the snow, a predetermined space is left inside the outer membrane 1 as shown in Fig. 5. It is desirable to provide the internal membrane 13 and maintain the internal membrane in the entire couple 8, thereby increasing the thermal efficiency. It is necessary to use a highly transparent film material for the internal film 13 so as not to obstruct daylight, and an opening is provided as necessary.

As explained above, according to the present invention, it is possible to melt and remove accumulated snow by heating one layer at 7 o'clock in the morning, thereby eliminating overloads, uneven loads, and poor lighting caused by accumulated snow on membrane roofs. can do.
