DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a roof structure for a greenhouse or the like.

[0002]

2. Description of the Related Art When roof glass is roofed in a greenhouse or the like, the upper glass sheet is generally superposed on the upper surface of the lower glass sheet, similarly to the case of roof tiles. For example, see JP-B-53-22428, JP-A-1-60659, and JP-B-57-43705. Such a structure is convenient for flowing rainwater from the upper side to the lower side,
When a particularly large glass is attached, there is a problem that construction work on site is difficult, and the strength is weak when it is blown by a strong wind.

[0003] Accordingly, the present applicant has assembled the entire periphery of a square plate glass in a grid shape with rafters and joints made of an aluminum molded product on an inclined beam, and further pressed the four sides of the glass plate with holding members arranged on them. (Japanese Patent Application No. 5-273208, Utility Model Registration No. 3005)
No. 350). Since such a greenhouse can employ a sheet glass several times as large as the conventional one, there is an advantage that the construction work is simplified and the lighting efficiency is improved.

[0004]

Since the greenhouse proposed by the present applicant uses rafters and joints made of extruded aluminum, the production cost is high. In addition, since the rafters and the joining material are assembled three-dimensionally on the inclined beams, the daylighting rate is not so high for sunlight from oblique directions. The present invention can basically adopt a sheet glass of the same size as the greenhouse proposed by the present applicant,
It is an object of the present invention to provide a roof structure such as a greenhouse in which manufacturing and construction costs are low and the lighting efficiency is further improved for sunlight in oblique directions.

[0005]

A roof structure such as a greenhouse according to the present invention comprises a plurality of inclined beams arranged in parallel with each other.

Is shown. In addition, a line 10 in the inclined direction schematically shows the position of a glass mounting vertical member (hereinafter, simply referred to as a mounting vertical member) or an inclined beam thereunder, and a horizontal line 11 shows the position of a purlin material. ing. The structural members for supporting the glass plate 12 on the surface of the greenhouse 1 are substantially the same as the conventional greenhouse, as shown in FIGS. 5 and 6, and are located at the positions of the vertical lines 13 on the side walls 6, 7 in FIG. A mountain-shaped ramen consisting of a stud 14 and an inclined beam 15 at the position of the oblique line 10 is vertically arranged at a pitch P3 of about 3 m, and a brace 16 is stretched between adjacent studs 14. In addition, reference numeral 17 in FIG.

Next, returning to FIG. 1, the structure of the roof 2 will be described in detail. Purlin members 18 are horizontally arranged between adjacent inclined beams 15 at a pitch P4 of about 1200 mm. The purlin 18 has substantially the same length as the interval between the inclined beams 15, and both ends thereof are fixed to the side surfaces of two adjacent inclined beams 15. More specifically, as shown in FIGS. 2 and 4, a support bracket 19 is fixed substantially horizontally to the side surface of the inclined beam 15, and both ends of the purlin 18 are placed on the support bracket 19, and And is fixed by bolts 20.

In this embodiment, the inclined beam 15 is made of H-shaped steel as in the prior art. The support bracket 19 is made of an angle material (angle steel) as shown in FIG. 3 and is arranged in a V-shape that opens upward, and its root end is welded to the side surface of the inclined beam 15 by welding or the like. It is fixed at. The purlin 18 is made of thin lip grooved steel, and its opening 21 is directed upward. Purlin material 1
The upper surface of 8 is flush with the upper surface of the inclined beam 15. Both the purlin 18 and the inclined beams 15 can be manufactured by hot-dip galvanizing a structural steel.

The support bracket 19 is, as shown in FIG.
Although it is provided substantially horizontally on both sides of the side surface of the inclined beam 18, it is preferable that the free end is fixed so that it is slightly higher than the horizontal. As a result, the purlin 18 is supported in a shape in which the center portion is warped upward, so that when the purlin 18 is bent by the weight of the glass plate 12, it becomes substantially horizontal. The support bracket 19 has another hole 22 at the base side in addition to the hole through which the bolt 20 passes, and the hole 22 is used to insert a lever rod for adjusting the inclination of the support bracket 19. Hole.

As shown in FIG. 3, a glass mounting cross member (hereinafter referred to as a mounting cross member) 30 made of a weather-resistant material is mounted on the upper surface of the purlin 18. Mounting cross member 3
0 is an intervening part 3 interposed between the edges of the upper and lower glass plates 12
2 and a plate-like pressing portion 33 provided on the upper surface of the interposition portion 32, and is a long material having a substantially T-shaped cross section. The intervening portion 32 is shaped like a square pipe, and has a slot 35 for passing a T-bolt 34 having a square head on the lower surface.
Is formed, and the entire side wall and the remaining lower surface portion are
A T-slot is slidably engaged with the head of the T-bolt 34.

Reference numeral 36 in FIG. 3 denotes a seal member made of synthetic rubber such as ethylene propylene rubber, which is provided between the lower edge 12a of the upper glass plate 12 and the upper edge 12b of the lower glass plate 12 and the interposed portion 32. Is provided with a cushioning material 37 made of a foamed sheet (sponge) of ethylene propylene rubber. The lower edge 12a of the upper glass plate 12 and the upper edge 12b of the lower glass plate 12 are sandwiched and held between the sealing material 36 and the holding portion 33. Therefore, there is no step between the upper glass plate and the lower glass plate, and the glass plate is attached to the upper surface of the purlin 18 so as to be flush. Note that the glass plate 12 in FIG. 3 uses a laminated glass in which a synthetic resin sheet is sandwiched between two glass plates and bonded. However, it may be a single piece of glass, or a double-layered glass having a heat insulating layer in some cases.

The mounting cross member 30 can be integrally formed by extruding aluminum. In addition, when it is susceptible to corrosion, such as when used in a barn such as a pig farm, it is preferable to manufacture from a highly corrosion-resistant material such as a stainless steel plate. In that case, it can be manufactured by, for example, bending and welding a stainless plate material. In the embodiment of FIG. 3, the purlin 18 in the form of a grooved steel with a lip is inserted into its opening 2.
1 is arranged so as to face upward. When dew condensation occurs on the inner surface of the glass plate 12, the dew forms as water droplets and is collected so as not to cover crops inside the greenhouse. Can be flowed.

As shown in FIG. 4, a substantially T-shaped glass mounting vertical member (hereinafter referred to as mounting vertical member) 40 is mounted on the upper surface of the inclined member 15. A plate-like holding portion 41 for sandwiching the side edge of the glass plate 12 in the mounting vertical member 40.
And a pair of interposed portions 42 protruding from the lower surface thereof. Each of the interposed portions 42 is provided with a T-shaped groove 45 for slidably engaging a head of a T-bolt 44 for attaching the mounting vertical member 40 to the inclined member 15. Mounting vertical member 4
Numeral 0 is disposed on the upper surface of the inclined member 15 via a seal member 46 such as ethylene propylene rubber, and is fixed to the inclined member 15 by a T bolt 44. As a result, both side portions of the glass plate 12 are supported on the upper surface of the inclined beam 15, and are fixed by the mounting vertical members 40 with play in the left and right direction with the interposed portion 42.

Between the glass plate 12 and the holding portion 41, a buffer material 47 made of a foamed sheet (sponge) such as ethylene propylene rubber is interposed. 3 is also held down by the mounting vertical member 40 together with the glass plate 12. On both sides of the lower part of the inclined material 15, a purlin material 18 is provided.
A gutter section 48 for collecting dew condensation generated on itself is provided. The vertical mounting member 40 attached to the inclined member 15 can also be formed of a metal material having high weather resistance, such as an extruded aluminum product or a stainless welded product.

The roof structure constructed as described above is shown in FIG.
As shown in the figure, a stud 14 is erected on the ground, an inclined beam 15 is assembled thereon, a purlin material 18 is stretched between them, and a glass plate 12 is arranged on them while being arranged in order from one side and the lower side. The mounting vertical members 40 are sequentially attached to the inclined beams 15, and the mounting horizontal members 30 are attached to the purlin 18, whereby the shapes shown in FIGS.
Similarly, the front and rear side wives 4 and 5 and the side walls 6 and 7 are similarly fitted with the purlin 18 to the stud 14 and the glass plate 12 is fitted thereinto, and the mounting vertical member 40 and the mounting cross member 30 are attached. You can easily assemble it just by attaching it. As described above, the seal members 36, 37, and 4 are provided between the inclined member 15 and the mounting vertical member 40 and the glass plate 12, and between the purlin 18 and the mounting horizontal member 30 and the glass plate 12, respectively.
6, 47 are interposed. Usually, various caulking materials and sealants are interposed at the time of assembling and construction to ensure the sealing action.

FIG. 7 shows the wives 4, 5 and the roof 2 of the greenhouse of FIG.
2 shows an example of the configuration of a connecting portion with the above. A flat bar 4 receiving the glass plate 12 of the front or rear side wives 4, 5 on the upper side of the studs 14 of the wives 4, 5 on the side surface of the inclined beam 15.
9 and a glass plate 12 between the flat bar 49 and the flat bar 49.
The glass pressing member 50 is attached so as to sandwich the. The vertical mounting member 40 on the upper part of the inclined beam 15 and the glass holding member 5
A sealing material 52 is interposed between the horizontal rib 51 and the horizontal rib 51. In addition, a sealing material 52 for sealing a gap between the connection portions is provided on a side surface of the glass pressing member 50.

In the greenhouse roof structure configured as described above, the periphery of the glass plate 12 is inserted between the purlin 18 and the mounting cross member 30 and between the inclined beam 15 and the mounting vertical member 40, Since the glass plate 12 is firmly surrounded and supported by these four members, the glass plate 12 is not blown by strong wind. Therefore, a glass plate as large as about 3 m on the left and right can be adopted. Further, it is not necessary to use a large number of rafters and joining materials, and the glass plate can be sufficiently supported only by the inclined beams and the purlin material. Moreover, in this roof structure, the number of glass plates 12 is reduced to about one-fifth of that in the conventional greenhouse, so that the assembling work is greatly simplified. Furthermore, since the purlin material is interposed between the inclined beams,
Both have a so-called planar configuration, and shadows are less likely to be formed than in a conventional structure in which a purlin material and a joining material are stacked on an inclined beam. Therefore, the lighting efficiency is high.

In the above embodiment, a glass plate is used as the light-transmitting plate, but a synthetic resin plate having a high strength and a high light-transmitting property, such as a polycarbonate material, can also be used. The vertical mounting member and the horizontal mounting member can be made of a metal material such as aluminum or stainless steel, or, for example, a synthetic resin, particularly a fiber-reinforced synthetic resin. In the above-described embodiment, the H-shaped steel is used as the inclined beam. However, an inclined beam made of wood products or other materials, such as a large-sized laminated wood, may be employed.

Further, the roof structure of the present invention can be applied to a roof structure of a hall or other buildings in addition to the above-mentioned agricultural buildings such as greenhouses and livestock barns. In that case, a structural material such as the above-described large-sized laminated material can be used for the inclined beams and the purlin material.

[0025]

According to the roof structure of the present invention such as a greenhouse, since the entire periphery of the light-transmitting plate is fixed, a large light-transmitting plate having high supporting strength can be adopted. Therefore, the number of parts is small and assembly is easy. In addition, the number of rafters is greatly reduced, and since the inclined beams and the jointing material form a so-called planar lattice structure, the daylighting rate is extremely large as compared with a conventional greenhouse.
