Description

The present invention relates to a pipe house applied to agriculture or facility horticulture, and realizes a structure that can withstand strong winds such as typhoons while being a simple structure.

In a house for horticulture, in order to be able to withstand typhoons, etc., it is common to construct a main frame with steel frames and a concrete foundation structure. Since it takes a period of time, the high cost prevents the spread. Also, dismantling and relocation are extremely difficult. On the other hand, the pipe-structured house is a simple structure formed by pipes, and the foundation work and other constructions are also simple. As a result, it can be realized at low cost, but it is disadvantageous in that it is weak against typhoons.

Under these circumstances, various improvements have been made in order to increase the wind resistance as much as possible in a pipe house with a simple structure. For example, as described in Japanese Patent Application Laid-Open No. 2003-259742, It has been proposed to fix a horizontal plate and a radial slat on the side of the column, insert it into a vertical hole dug into the ground, and embed it into a pipe house column. On the other hand, regarding the structure of the above-ground part of a pipe house, it is common to enhance wind resistance by means such as reinforcement using braces or wires, or by using a lot of reinforcing materials.
JP2003-259742

Post structure, such as the Patent Document 1, although it is very effective in enhancing the wind resistance, and if a strong wind continues long, is insufficient when wind is strong, damage inevitable. The technical problem of the present invention is to make it possible to effectively improve wind resistance while paying attention to such problems and taking advantage of the characteristics of an inexpensive pipe house with a simple structure.

The technical problem of the present invention is solved by the following means. Claim 1, the side surface of the pipe house, can you make a plurality of struts for scaffold into the ground at a predetermined pitch, end uprights wife surface side, one-third or less of the narrow strut pitch of the strut pitch In addition, the wind-resistant pipe house is characterized in that the lower ends of the columns having a narrow pitch are connected to each other by a horizontal plate in the ground . Thus, keep upright side struts into the ground at a constant pitch, the end uprights of his wife surface side, because you have to 1/3 or less of the narrow strut pitch of the strut pitch, the most powerful wind pressure The strut on the wife side can be strengthened. And since the lower end of this edge part support | pillar and the adjacent support | pillar is mutually connected by the horizontal board in the ground, lower ends are mutually connected and it becomes an integral structure, and intensity | strength improves further. Further, when the connecting means is a horizontal plate and is buried in the ground, the connecting means functions as a support for preventing the support from coming off, so that the support structure is further strengthened.

According to the second aspect of the present invention, at least the lower end of the support near the side surface and the lower end of the support facing the wife surface among the side support columns are connected to each other by a horizontal plate in the ground. The wind-resistant pipe house according to claim 1. Thus, among the struts on the wife side, at least the lower end of the struts near the side surface and the lower end of the side struts on the side of the wife surface are connected to each other with a horizontal plate in the ground, so In addition, since the lower ends of the corner end columns are connected to the lower ends of the two columns at an interval of 90 degrees, a more robust column structure is obtained.

According to a third aspect of the present invention, in the pipe house, a wire is provided between the ridge portion and the base side of the side column so that a wire can be stretched between at least the ridge portion and the base side of the ground portion of the side column. The wind-resistant pipe house according to claim 1 or 2, wherein a connecting means is provided. As described above, the wire connecting means is provided on the ridge portion and the base side of the side column so that the wire can be stretched between the base side of the ground portion of the side column and the ridge portion. Since connection means are prepared in advance in this way, when the typhoon approaches, just connect the wire to the connection means on the base side of the peak and side column, and tighten the wire with the turnbuckle, the most strength It is possible to prevent the weak roof portion from being crushed by wind pressure.

A fourth aspect of the present invention is the wind resistant pipe house according to the first, second, or third aspect, wherein the height of the peak portion of the pipe house is less than 3 m. In this way, the height of the peak part of the pipe house is less than 3 m, so the wind perception is weaker than that of a pipe house with a normal peak height of 3 m or more. Wind resistance can be further strengthened in combination with reinforcing the wire and stretching the wire between the ridge and the side strut base.

According to the fifth aspect of the present invention, on the side of the pipe house, a plurality of support columns for a frame are stood in the ground at a constant pitch, and the end support column on the end face side is set to a narrow support column pitch of 1/3 or less of the support column pitch. When a strong wind such as a typhoon hits a pipe house, it is reinforced by stretching a wire at least between the peak and the base of the side post, and if the strong wind leaves, it will interfere with the work in the house. In order to prevent this, the above-mentioned reinforcing wire is retracted, and this is a strong wind countermeasure method in a wind-resistant pipe house. As described in claim 3, since the wire connecting means is pre-equipped on the base side of the ridge and the side column, when a typhoon or the like approaches, the ridge and the side of the side column By stretching the wire between them, the roof part that is most vulnerable to strong winds can be effectively reinforced in a short period of time. Since the wire is detachable, when the strong wind leaves, it is only necessary to remove the reinforcing wire from the connecting means so as not to get in the way so as not to get in the way of work in the house.

As of claim 1, since the aft upright side struts into the ground at a constant pitch, the end uprights of his wife surface side, are to 1/3 or less of the narrow strut pitch of the strut pitch, most The strut on the side of the wife that receives a strong wind pressure can be strengthened. And since the lower end of this edge part support | pillar and the adjacent support | pillar is mutually connected by the horizontal board in the ground, lower ends are mutually connected and it becomes an integral structure, and intensity | strength improves further. Further, when the connecting means is a horizontal plate and is buried in the ground, the connecting means functions as a support for preventing the support from coming off, so that the support structure is further strengthened.

As in claim 2, at least the lower end of the strut near the side surface and the lower end of the side strut on the side of the wife surface are connected to each other by a horizontal plate in the ground. The side struts are strengthened, and the lower ends of the end struts at the corners are connected to the lower ends of the two struts at an interval of 90 degrees, resulting in a more robust strut structure.

According to a third aspect of the present invention, wire connecting means is provided on the ridge portion and the base side of the side column so that a wire can be stretched between the base side of the ground portion of the side column and the ridge portion. Since connection means are prepared in advance in this way, when the typhoon approaches, just connect the wire to the connection means on the base side of the peak and side column, and tighten the wire with the turnbuckle, the most strength It is possible to prevent the weak roof portion from being crushed by wind pressure.

Since the height of the ridge part of the pipe house is less than 3 m as in claim 4, the wind contact is weaker than that of a pipe house having a normal peak height of 3 m or more, and the angle between the side surface and the wife surface as described above. Wind resistance can be further strengthened in combination with strengthening the struts of the part and stretching a wire between the peak and the side strut base.

As described above, since the wire connecting means is preliminarily provided on the base side of the ridge and the side column, when a typhoon or the like approaches, the base of the ridge and the side column as described in claim 5. By laying the wire between the sides, the roof part that is most vulnerable to strong winds can be effectively reinforced in a short period of time. Since the wire is detachable, when the strong wind leaves, it is only necessary to remove the reinforcing wire from the connecting means so as not to get in the way so as not to get in the way of work in the house.

Next, an embodiment of how the wind-resistant pipe house according to the present invention is actualized will be described. FIG. 1 is a perspective view showing the whole of a wind-resistant pipe house according to the present invention. This figure shows only the framework without the insect net or vinyl sheet. Between the left side surface A and the right side surface B, an arch-shaped roof portion 1 is formed. On the left and right side surfaces A and B, a plurality of pipe-made side surface columns 2 are set up and inserted into the ground. And the arch-shaped pipe 3 is connected between the upper ends of the supports 2 and 2 on both the left and right side surfaces. The horizontal pipes P1, P2, P3, and P4 are connected and fixed to the support columns 2 and the arched pipes 3 in the horizontal direction. P1 is a lower horizontal pipe, P2 is a shoulder horizontal pipe, P3 is a middle horizontal pipe, and P4 is a ridge pipe or a ridge horizontal pipe.

The front face C and the rear face D are also erected by inserting a plurality of face posts 4 into the ground, and the upper ends of each of the face posts 4 are arched on the face side. It is connected to the pipe 3. And the horizontal pipe P5 is connected and fixed also to each wife surface support | pillar 4 .... In addition, although the door for entrance / exit is arrange | positioned at the wife surface side, illustration is abbreviate | omitted. In the frame structure as described above, an insecticidal net is covered on the entire surface of the frame using an attachment means called Binipet (trademark), and a vinyl sheet is placed on the net to be fixed.

Each side support 2 ... and the end face support 4 ... have a structure as shown in FIGS. FIG. 2 is a perspective view and a plan view of the columns 2 and 4. The struts 2 and 4 are usually made of metal pipes, and a horizontal plate 7 is fixed to the lower end of the struts 2 and 4 at a right angle to the struts 2 and 4 by means such as welding. If the columns 2 and 4 have a diameter of about 5 cm, one side of the horizontal plate 7 is suitably about 15 cm, which is about three times the diameter of the columns 2 and 4. The struts 2 and 4 have vanes 8 that are fixed by welding in the radial direction on the side surfaces of the portions embedded in the ground. The slats 8, may be fixed two to one 80 degree intervals, Ru possible der is good, or in only one provided by fixed four to 90 degree intervals, as shown in a cross shape . When provided at intervals of 180 degrees, slits may be formed at intervals of 180 degrees near the lower ends of the columns 2 and 4, and one iron plate may be inserted therein and fixed by welding.

The lower ends of the blades 8 and 8 are connected and fixed to the upper surface of the horizontal plate 7. That is, the connecting portion 9 is fixed by welding to each other. The dimension in the diameter direction of the blades 8 , 8 is preferably about the same as the dimension of one side of the horizontal plate 7. The thickness of the blade plate 8, the horizontal plate 7, and the support columns 2, 4 is not particularly limited, but about several mm is suitable. In addition, the hole which leads in the support | pillars 2 and 4 is opened in the center of the horizontal board 7, and the rain water in the support | pillars 2 and 4 drains into the ground.

When using the support columns 2 and 4, as shown in FIG. 3, the horizontal plate 7 and the blade plates 8 and 8 are inserted and buried in the ground. That is, a vertical hole having a size enough to contain the horizontal plate 7 and the blades 8 and 8 is dug in the ground, and the horizontal plate 7 and the blades 8 and 8 of the columns 2 and 4 are inserted therein. After the uprights 2 and 4 are erected, earth and sand are backfilled on the horizontal plate 7 and the blade plates 8 and 8. Stones or the like may be embedded on the horizontal plate 7 for pressurization.

Thus, when the horizontal plate 7 at the lower end of the columns 2 and 4 and the portions of the side blades 8 and 8 are inserted and embedded in the vertical holes dug into the ground, the horizontal plate 7 acts as a stopper and prevents settlement. The support columns 2 and 4 do not easily come off or sink. Moreover, the shaking of the support | pillars 2 and 4 can also be suppressed. In particular, since the blade plates 8 and 8 are attached, it is possible to effectively suppress the swing of the columns 2 and 4 against an external force perpendicular to the surface of the blade plates 8 and 8. Note that the blades 8 and 8 also prevent the support columns 2 and 4 from rotating. As described above, since the pillars 2 and 4 having a simple structure having the horizontal plate 7 and the blades 8 are simply embedded in the ground, the pillars 2 and 4 can be prevented from shaking, coming off, or sinking due to a typhoon. It is extremely effective as a fixing structure for the 2 and the wife face support 4.

The side struts 2 ... and the end face struts 4 ... in FIG. 1 are set up at a pitch of 2.4 m, for example, but the struts 24 at the corners of the end face C side and the side faces A and B side, The side strut 2a and the end face strut 4a adjacent to the part strut 24 have a structure as shown in FIG. The pitch between the corner struts 24 and the adjacent side struts 2a is set to 0.6 m with respect to the pitch 2.4 m of the side struts 2. Moreover, the horizontal plates 7, 7 at the lower ends of the columns are connected in a bridge shape by a horizontal connecting plate 7a. The horizontal plates 7, 7 a, 7 may be an integrated single plate, or a separate horizontal plate 7 a may be provided between the square horizontal plates 7, 7 as shown in FIGS. You may weld and connect. Further, the vertical iron plate 10 is erected on the horizontal connecting plate 7a and welded. The vertical iron plate 10 is also welded and fixed to the adjacent corner column 24 and the side surface of the side column 2a .

In this way, the corner struts 24 and the adjacent side struts 2a are connected by the horizontal connecting plate 7a and the vertical iron plate 10, so that they are inserted and buried in the grooves dug in the ground. By being connected to each other, the strength and strength of shaking and falling off in strong winds and other directions become robust. The pitch p between the side pillars 2a adjacent to the corner pillars 24 is desirably a narrow pillar pitch of about 1/3 or less of the pitch P between the side pillars 2.

The pitch i of the support posts 4 on the side of the end face C, D is 1 m in the illustrated example, but only the pitch with the support post 4 adjacent to the corner support post 24 may be narrower than the other support post pitch 1 m. Since it is only 1 m from the beginning and is becoming narrower, it is not always necessary to make it narrower. Even between the adjacent struts 4 a and corner post 24 wife surface, are connected like a bridge between the horizontal plate 7, 7 at the lower end a horizontal connecting plate 7b. Moreover, on this horizontal connecting plate 7b, Yes welded make a vertical steel plate 11, the vertical steel plate 11, both side surfaces of the adjacent corner posts 24 and Tsumamen post 4 a is fixed by welding. Therefore, Wife side pillar 4 a adjacent to corner post 24 is also not only improves wind resistant, corner post 24 is connected by a horizontal connecting plate 7b, 7a also side struts 2 a with wife surface post 4 a Therefore, the strength against the wind pressure in each direction is further improved.

Since the vertical iron plates 10 and 11 are weak in the compression direction, they may be connected by pipes similar to the columns 2 and 4 at positions near the upper ends of the vertical iron plates 10 and 11 in order to avoid buckling. The height of the blades 8 and 8 is, for example, 60 cm, and the blades 8 and 8 are embedded in the ground so that the upper ends of the blades 8 and 8 are located at a depth of about 15 cm in the ground. In the position of the ground surface E, between the side surface pillars 2 a and Tsumamen post 4 a, when provided with a connecting pipe of the chain line 12 direction connected to the diagonal directions, each strut 2 a, 4 a, 24 a wind Sexually improves. If the connecting pipe in the oblique direction is provided at the height of the blades 8 and 8, it is buried at a depth of about 15 cm in the ground, so that the oblique reinforcing pipe does not get in the way.

1 and FIG. 5 is a single continuous body. However, as shown in FIGS. 2 and 3, the horizontal plate 7 is placed on the pipe for embedding separately from the side pillars on the shoulder side. And blade plate 8 are installed, embedded in the ground as shown in FIG. 2 and FIG. 3, and then the shoulder side pillars are inserted into the ground part, and bolts are inserted into the lateral holes 20 to connect them. It is good to do. Pipes other than the side supports 2 should be assembled into a pipe house as shown in FIG. 1 by connecting short pipes, avoiding long materials that are difficult to transport and handle. The site | part to connect is arbitrary. Moreover, it can replace with the vertical iron plates 10 * 11 in FIG. 4, and can also use a punching metal, a metal mesh, etc. FIG. You may comprise a reinforcing bar in the shape of a lattice.

Figure 5 is a longitudinal sectional view of the X-X direction in House 1, are connected to arcuate pipe 3 between the upper end of the pillar 2, 2 left and right side surfaces. A normal house is reinforced by passing a beam pipe between the upper ends of the side supports 2 and 2, but in the case of the present invention, such a reinforcement pipe is not provided. Therefore, although it is inferior in wind resistance, since a wire is stretched and reinforced when a strong wind comes, a problem does not arise in particular. A connecting ring 13 for attaching a wire is fixed to the peak of the arched pipe 3 by welding. In addition, a connection ring 14 is welded and fixed to a lower portion or a root portion of the left side column 2, and a connection ring 15 is fixed to a lower portion or a root portion of the right side column 2 by welding. If necessary, the connection rings 16 and 17 may be fixed by welding on the shoulder S as well.

As described above, since the connecting rings are provided in advance on the side support columns 2 and the arch pipe 3 side, when the typhoon approaches, the connecting rings are used to stretch the wires W1 to W3. Can do. That is, the wire W1 is stretched between the lower connection ring 14 and the peak connection ring 13 of the left side column 2 and tightened with a turnbuckle. Further, a wire W2 is stretched between the lower connecting ring 15 and the peak connecting ring 13 of the right side column 2 and tightened with a turnbuckle. In this way, as shown in FIG. 1, since the wires W1 and W2 are stretched between all the side columns 2 ... and the ridges, even if a typhoon arrives and a strong wind acts on the roof, The roof can be prevented from being crushed. That is, even if a force in the direction in which the wind pressure acts between the arched pipe 3 and the side column 2 is expanded, it is blocked by the wires W1 and W2, so that the roof can be prevented from being crushed. If necessary, if the wire W3 is stretched between the connecting rings 16 and 17 on the left and right shoulders and tightened with a turnbuckle, it acts as a resistance against the wind pressure from directly above. Since the wires W1, W2, and W3 interfere with the work in the house, when the typhoon leaves, the wires W1 to W3 are removed or loosened from the connection rings 13 to 17 to disturb the wires W1 to W3. Keep it away and tie it to a nearby skeleton.

As shown in FIG. 1, when also between adjacent struts 2 and A Chipaipu 3 tensioning the wire W4, W5, is more effective. That is, the wire W4 is stretched between the ridge connecting ring 13 and the shoulder connecting rings 16 and 17 adjacent to each other. Therefore, as is apparent from FIG. 5, the purpose of the wire W4 is not to prevent the roof from being crushed by a strong wind but to reinforce the adjacent arch pipes 3. As shown in FIG. 5, the wire connecting rings 18 and 19 are also fixed by welding at the position of the middle horizontal pipe P <b> 3 of the arch pipe 3. As shown in FIG. 1, a wire W <b> 5 is stretched between the middle connecting rings 18 and 19 and the adjacent shoulder connecting rings 16 and 17. The wires W5 ... and W4 ... are stretched between the adjacent peak connecting ring 13, the middle connecting rings 18, 19, and the shoulder connecting rings 16, 17, so that the adjacent arch pipe 3 ... and the side column 2 to between ..., not only pulling direction also acts as a reinforcement in the compressing direction. Since these wires W4 and W5 do not disturb the work in the house, they may be kept stretched at all times except during a typhoon. In addition, when a wire is stretched in an X shape, for example, between the middle coupling ring 19 facing the lower coupling ring 14 and between the middle coupling ring 18 facing the lower coupling ring 15 also on the wife surface or inside the house. Is more effective.

As shown in FIG. 1, a wire W6 may be stretched between the adjacent side struts 2. In place of this wire W6, an oblique pipe may be provided. A diagonal 20 is attached between the shoulder of the corner support 24 on the side of the wife face and the lower part of the adjacent support 2 to prepare for wind pressure in the compression direction from the face side. In the case of the arched roof structure as shown in FIG. 1, in principle, the left and right side surfaces are all symmetrical.

As described above, according to the wind resistance pipe house of the present invention, or reinforced by connecting the strut bottom in the side pillars or wife surface supports and the ground with a narrow standoff pitch only wife surface, the wire only when typhoon performs a typhoon measures and stretched, typhoon and remove Once you left, than so that does not interfere with the work of the house, is very reasonable as strong winds measures in the pipe house of inexpensive simple structure, in the House There is no hindrance to production work. Therefore, it is expected to spread as a pipe house complete with strong wind countermeasures.

It is a perspective view which shows the whole content of the wind-resistant pipe house by this invention. It is the detail of a support | pillar, (1) is a perspective view, (2) is a top view. It is a side view of the state where the lower end of the support was buried in the ground. It is a perspective view which shows the relationship between the corner | angular part support | pillar in an underground, and an adjacent support | pillar. It is a longitudinal sectional view of the X-X direction in house of Figure 1.
