Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for attaching a face plate to an arch-type greenhouse, and is particularly aimed at applying a synthetic resin face plate to an arch-type greenhouse.

Traditionally, arch-shaped greenhouses with a semi-cylindrical appearance,
It has excellent strength against external forces such as wind pressure and snow accumulation, and is available in single-panel type (see Figure 1) or multi-panel type (see Figure 2). By the way, most arch-type greenhouses are assembled by bending galvanized steel pipes into an arc shape to form an arch material, and then stretching a synthetic resin film such as vinyl chloride onto the arch material. However, conventional arch-shaped greenhouses using vinyl chloride film as a covering material have drawbacks in weather resistance, resulting in reduced light transmission during use and damage due to reduced strength.
The dressing had to be replaced every season or every year or two. Replacing this covering material requires an enormous amount of labor as greenhouses tend to become larger year by year, and there remains the problem of disposing of the film when it is no longer needed, so an improvement in this area has been strongly desired. In this regard, using a material such as methacrylic resin, which has excellent weather resistance, as the covering material will extend the life of the covering material and eliminate the hassle of replacing it, but since conventional arch-shaped greenhouses are made exclusively for film, hard synthetic resin It is not possible to lay boards, and such greenhouses have not yet appeared.

The present invention has been made in view of this situation, and the gist thereof is to provide a plurality of grooves having at least two inverted gutter-like engagement grooves 11 in the longitudinal direction and curved or inclined in the longitudinal direction. a synthetic resin face plate 1, a holding member 2 having a string storage groove 21 at the outer center approximately and whose cross-sectional shape approximately matches the cross-sectional shape of the engagement groove 11, and a string made of an appropriate material. 3, the synthetic resin face plate 1 is sequentially installed by engaging the engagement groove 11 with the arch material A of the arch-type greenhouse that has been assembled in advance, and the outside of the engagement groove 11 of the synthetic resin face plate 1 is the presser material 2 on the side
are brought into contact with each other continuously or intermittently, and further, the string 3 is passed through the string storage groove 21 of the presser material 2, and the string 3 is tied tightly, and the synthetic resin face plate 1 is mounted by pressing it against the arch material A. The first invention provides a face plate mounting structure for an arched greenhouse characterized by the following: a plurality of grooves having at least two inverted gutter-like engagement grooves 11 extending in the longitudinal direction and curved or inclined in the longitudinal direction; A synthetic resin face plate 1, a presser plate 2' having a pair of string storage grooves 21' at both outer ends and whose cross-sectional shape approximately matches the cross-sectional shape of the engagement groove 11, and an appropriate material. A string 3 consisting of
The synthetic resin face plate 1 is sequentially laid by engaging the engagement groove 11 with the arch member A of the arch-type greenhouse that has been assembled in advance, and the retaining member is placed outside the engagement groove 11 of the synthetic resin face plate 1. 2' are brought into continuous or intermittent contact with each other, and the strings 3 are passed through the pair of string storage grooves 21 of the presser material 2' and the strings 3 are tied tightly, and the synthetic resin face plate 1 is pressed against the arch material A. The second invention provides a structure for attaching a face plate of an arch-type greenhouse, which is characterized in that it is attached in this manner.

Hereinafter, the present invention will be explained in more detail with reference to drawings of embodiments.

Figures 1 and 2 show the framework of an arched greenhouse in the face plate mounting structure of the present invention.
Figure 1 shows an example of a single-building type, and Figure 2 shows an example of a multi-building type. Although the face plate mounting structure of the present invention can be applied to any type of arch-shaped greenhouse, it is particularly suitable for an arch-shaped greenhouse of the type in which the purlin material B is located inside the arch material A as shown in the figure. In the figure, C is a channel steel used in the multi-building type, and D is a support.

Figures 3 to 8 show examples of the synthetic resin face plate 1 used in the present invention.
is obtained by molding a transparent synthetic resin such as methacrylic resin (including one reinforced with glass fiber), vinyl chloride resin, or FRP as shown in the figure. The synthetic resin face plate 1 shown in FIGS. 3 and 4 has the most basic shape.
Three inverted gutter-like engagement grooves 11 are arranged in succession in the longitudinal direction, and are slightly curved in the longitudinal direction, as is clear from FIG. The inverted gutter-like engagement groove 11 provided in the synthetic resin face plate 1 serves as an engagement groove for engaging the synthetic resin face plate 1 with the arch material A, and in order to install the same face plate 1 on the arch material A, at least two Requires. Note that the shape of the inverted gutter-like engagement groove 11 is not limited to that shown in the drawings, and may be a little wider. Fig. 5 shows another example of the synthetic resin face plate 1, in which the space between the three inverted gutter-like engagement grooves 11 is slightly bulged upward when viewed from the cross-sectional direction (X-X line in Fig. 3). It is something that Figure 6 also shows another example.
It has a continuous waveform when viewed from the cross-sectional direction, and this waveform also serves as the inverted gutter-like engagement groove 11. The synthetic resin face plate 1 is slightly curved as shown in FIG. 7, but the degree of this curvature is determined by the curvature of the arch material A and the like. Of course, instead of being curved, it may be formed to be inclined in stages as shown in FIG. In short, it is sufficient that the synthetic resin face plate 1 is curved or inclined so that it fits comfortably when laid on the arch material A.

9 and 10 are perspective views showing a first embodiment of the face plate mounting structure of the present invention, in which 1 is a synthetic resin face plate, 2 is a holding member, and 3 is a string. Here, the first invention is characterized in that it is attached using a holding member 2 as shown in FIG. That is, this presser member 2 is made of a metal material such as aluminum or a synthetic resin material, and has a string storage groove 21 approximately in the center outwardly.
In addition, the cross-sectional shape is the cross-sectional shape of the inverted gutter-like engagement groove 11 of the synthetic resin face plate 1 (the cross-section in this case is as shown in FIG.
- points to the X-ray direction). The string storage groove 21 is not limited to the illustrated example as long as it has a shape that allows the string 3 to be stored here and not to be accidentally removed. In the first invention,
Since the presser member 2 is bound with one string 3, the string storage groove 21 is provided at approximately the center on the outside. In addition, since the presser member 2 is brought into contact with the inverted gutter-like engagement groove 11 so as to straddle it, it needs to substantially match the cross-sectional shape of the engagement groove 11 . In this case, the degree of matching between the two cross-sectional shapes is not more than accurate, but during construction,
It is sufficient that the handle does not fall over on the engagement groove 11. Note that the material of the string 3 used in the present invention is not particularly limited, and strings having a certain strength and durability such as strings made of fibers such as hemp, strings made of synthetic resin, strings made of metals such as wire, etc. Any is fine as long as it is.

Next, a construction method of the face plate mounting structure of the first invention will be explained. Synthetic resin face plates 1 as shown in FIG. 3 are sequentially laid on the arch material A of an arch-type greenhouse that has been assembled in advance as shown in FIG. 1 or 2 while engaging the inverted gutter-like engagement grooves 11. . Normally, several synthetic resin face plates 1 are laid on one side of the slope of an arch-shaped greenhouse, and the entire installation is carried out by laying further synthetic resin face plates 1 in the depth direction, but the synthetic resin face plates 1 are overlapped in the direction of the slope. In order to prevent the sheets from shifting, it is preferable to use an adhesive tape 4 at the overlapping portion as shown in FIG. 9. Moreover, in order to improve the airtightness and watertightness of this part, a suitable packing may be interposed in this overlapping part. In addition, when installing a skylight at the top of the greenhouse or a side window on the side, lay the synthetic resin face plate 1 except for that part, and install the movable skylight or side window in that part. do it. Next, the presser member 2 is continuously or intermittently brought into contact with the outside of the inverted gutter-like engagement groove 11 of the synthetic resin face plate 1, and the string storage groove 2
Pass string 3 through 1 and bind it. In addition, 5 in the figure
is the support rod for string 3. Here, the term "continuously abutting the presser material 2" means that the length of the presser material 2 is the length of the inclined surface on which the synthetic resin face plate 1 is laid in an arched greenhouse, and the length of the presser material 2 is the length of the slope surface on which the synthetic resin face plate 1 is laid. It refers to contact across the length (actually, over the entire length of the inverted gutter-like engagement groove). When constructed in this manner, when the synthetic resin face plate 1 is pressed against the arch material A by tying the strings 3, the pressure can be applied to the entire length of the face plate 1, which is desirable. On the other hand, partially contacting this means that the presser member 2 cut short as shown in FIG.
Similarly, the string 3 is placed in the string storage groove 21 of the presser foot 2.
The synthetic resin face plate 1 is constructed so as to be pressed against the arch material A by tightening it through the arch material A. Compared to the former, in the latter case, the presser material 2 can be saved, although there are some disadvantages in uniformity of pressing force, time and effort of construction, etc.
In addition, when abutting the presser material 2, double-sided adhesive tape or adhesive may be used in combination to prevent the abutment position from shifting.

Since the first invention has the above-described structure, the synthetic resin face plate 1 can be easily laid on the assembled arch material A, and the synthetic resin face plate 1 can be attached to the inverted gutter-like structure. Since the fitting groove 11 is pressed from the outside by the presser material 2, it does not move or scatter unnecessarily, and the bondage string 3
It also has the advantage of being able to function without coming off because it is accommodated in the string storage groove 21 of the presser member 2.
Furthermore, the synthetic resin face plate 1 of the present invention is provided with at least two inverted gutter-like engagement grooves 11 in its longitudinal direction, which serve as a kind of reinforcing rib. The expansion characteristic of synthetic resins,
It also has the effect of absorbing shrinkage as much as possible.

FIG. 11 shows an embodiment showing the face plate mounting structure of the second invention, in which a pair of string storage grooves 21' are provided at both outer ends, and the cross-sectional shape is that of the inverted gutter-like engagement groove 11. It is characterized by the use of a presser member 2' that substantially matches the cross-sectional shape. To explain the mounting structure in this case, the synthetic resin board 1 used is the one shown in FIGS.
The one shown in Fig. 2 or Fig. 2 is used. Then, the work is exactly the same as in the first invention up to the step of laying the synthetic resin face plate 1 on the arch material A, and then the holding member 2' as shown in FIG. A pair of strings 3 made of the same material as in the first invention are brought into contact with the outside of the matching groove 11 continuously or intermittently, and are passed through the pair of string storage grooves 21' to be tied tightly. In this case, the cross-sectional shape of the presser member 2' must also substantially match the cross-sectional shape of the inverted gutter-like engagement groove 11, but in the second invention, since the string 3 is tied at both ends, the first Compared to the invention described above, the accuracy of matching between the two cross-sectional shapes may be more gradual. Note that the meaning of bringing the presser plate 2 into contact continuously or intermittently is as follows.
This is the same as the second invention, and it is also the same that a double-sided adhesive tape or an adhesive can be used together when making contact. FIG. 12 shows another example of the presser plate 2' used in the second invention, in which the shape of the string storage grooves 21' at both ends is simpler than that of the one in FIG. It is now possible to manufacture it through processing. Of course, this example can also be constructed in the same manner as the case shown in FIG. 11, and the operation and effect are the same.

Although the embodiment of the second invention has been described above, this invention is not essentially different from the first invention. However, since a presser member 2' that is somewhat different from the first invention is used, when pressing the synthetic resin face plate 1 against the arch material A, the pair of strings 3 apply a pressing force from both ends of the presser member 2'. acts,
The synthetic resin plate 1 can be mounted stably, and the presser member 2' will not move unnecessarily, which is very convenient.

Since the present invention has the above-described structure, it is possible to reliably attach a synthetic resin face plate to an arched greenhouse with a simple operation, and the synthetic resin face plate has a predetermined strength and can be installed easily. The face plate does not deform due to the expansion and contraction of the synthetic resin, and due to the action of the holding material and strings, it is stably attached over a long period of time and does not move or scatter unnecessarily. This invention is inexpensive and has high practical value as a structure for attaching the front plate of a greenhouse.
