DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple structure which can be used as a working house, a warehouse, a breeding house for livestock such as cows, horses, pigs, chickens, and other mushroom houses at a construction site.

[0002]

2. Description of the Related Art Conventionally, cattle and chicken breeding houses, for example, have reinforced concrete columns and roof skeletons, or lay corrugated slate or galvanized iron on the pillars as roofing materials. Some are ventilated and cooled.

[0003]

However, in the former reinforced concrete construction, the construction cost is high, so that in reality, construction of such a breeding house requires a public subsidy. In addition, the latter structure requires less construction cost like the former structure, but the rise of the temperature inside the structure is inevitable, so fans and the like are installed in high temperature regions,
Nevertheless, it is unavoidable that the temperature is still high, and as a result, livestock stunts and fatal accidents occur at a considerable rate.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, an object of the present invention is to provide a low-cost construction, excellent heat insulation effect, and a good environment in comparison with the prior art. Another object of the present invention is to provide a simple structure that is resistant to strong winds.

A second feature of the present invention is that the upper surface of the sheet material is covered with a sheet for preventing separation of the sheet material, and a windproof mesh sheet is attached to the frame with a predetermined gap below the sheet material. It is located.

[0007]

Embodiments will be described with reference to the drawings.
As shown in FIG. 1, the structure of the skeleton (body) according to the present invention includes a column 1 erected at a predetermined interval, a beam 2 supported by the top of the column, and supported by the upper surface of the beam. A rafter (rafter) material 3 provided in a direction intersecting with the beam material. In addition, this frame is
By inclining at 0 degrees, drainage from the upper surface of the sheet material 4 described later is improved.

As shown in FIGS. 2 and 3, a sheet material 4 is laid on the upper surface of the rafter material 3, and the sheet material is prevented from peeling off from the frame by wind protection of the sheet material. This sheet is formed into a mesh sheet having a hole width of about 1 to 5 mm using a constituent resin such as polyethylene. further,
The sheet material 4 and the separation preventing mesh sheet 5 are connected to each other by a lower surface 6 of the sheet material and a stopper 6 provided at an interval of about 50 cm. As shown in FIGS. 2 and 4, the structure of the stopper 6 is such that a groove-shaped stopper 61 having an open top surface and an enlarged bottom portion is fixed on the slack material 3 with screws at predetermined intervals. A sheet material 4 and a mesh sheet 5 are bent and inserted into the bottom of the groove of the stopper in a two-layer state.
A stop plug 62 that is continuous in a trapezoidal shape as shown in (B), that is, a zigzag shape and can be stretched against its elastic force is inserted so as to be positioned on the mesh sheet. In this insertion work, when the stopper plug 62 is extended and the stopper plug is narrowed and inserted, after insertion, the state shown in FIG. 4 is obtained by its own elastic restoring force. The mesh sheet 5 and the sheet material 4 are laid on the upper surface of the rafter 3 in a connected state.

[0009] As shown in FIG.
The windproof mesh sheet 7 is stretched downward with a predetermined gap. The windproof mesh sheet 7 is similar to the mesh sheet 5 for preventing peeling, and is formed of a synthetic resin into a mesh having a hole width of about 1 to 5 mm. The windproof mesh sheet 7 is provided for measures against wind storms, and the windproof mesh sheet reduces the speed of the wind rising from the holes. Therefore, the hole width of the windproof mesh sheet 7 is a problem. According to the experimental example, it has been found that when the mesh has a width of 2 mm, the wind speed toward the sheet material 4 can be reduced by almost half. Further, in front of the planted pillar 1 at the front position, a feed trough 8 for feeding the livestock is installed.

The sheet material 4 will be described. As shown in FIGS. 5 and 6, the air-permeable reinforcing material 42 is laminated on a non-woven fabric 41, and is pressed by a metal roll heated to 120 ° C. It is made by joining. And
The non-woven fabric 41 is made by fiberizing high-density polyethylene by a flash spinning method, and selects a high-density synthetic resin long-filament filament bonded and joined (for example, DuPont's “Tyvek 760AG” registered trademark). It is. The breathable reinforcing material 42 is formed by laminating a synthetic resin thread in a weft manner, and the synthetic resin thread is formed of a high-density polyethylene (density = 0.956 g / cm ³ , MFR
= 1.0 g / 10 min.) As an outer layer, a film having a three-layer structure is cut into a tape shape by coextrusion blown molding, and a stretching temperature of 11 is obtained by a hot plate contact stretching method.
It is stretch-oriented at 5 ° C. and a stretching ratio of 5.2 times, subjected to an Anning treatment at 120 ° C., and formed into a three-layer flat yarn having a fineness of 350 dr.
Is woven at a driving density of 8 × 8 yarns / inch with a Sulzer-type loom using this flat yarn as a weft yarn, and 115 °
C is pressurized by a metal roll heated, and the intersection of the processes is heat-sealed.
