About.

  A conventional pipe house used in agriculture, horticulture or the like generally has a frame structure in which a plurality of arch pipes standing vertically at intervals are connected and fixed by a purlin pipe extending horizontally. The pipe house having such a configuration has been studied in the past to improve wind resistance because there is a possibility that the pipe house may collapse during a strong wind due to the approach of a typhoon or the like.

  For example, in Patent Document 1, when a plurality of frames for a frame constituting a pipe house are placed on the ground at intervals, the column pitch is narrowed and the lower ends of the columns are connected to each other on the ground surface side. By doing this, it is described that the support on the side of the wife face that is easily affected by wind is strengthened.

It is a principal part side view which shows an example of the pipe house which uses the fixture shown in FIG. It is process drawing for demonstrating an example of the reinforcement method of the pipe house using the fixture shown in FIG.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a side view of main parts of a pipe house according to an embodiment of the present invention, and FIG. 2 is a plan view of main parts of the pipe house shown in FIG. As shown in FIG. 1 and FIG. 2, the pipe house 1 includes a framework 4 constituted by a plurality of arch pipes 2, a pair of extending members 6, 6 constituting a support portion that supports each arch pipe 2, and a framework. 4 and a sheet-like member 8 that is stretched to 4.

  The arch pipe 2 has a shape in which a cylindrical member having openings at both ends is curved in an arch shape along a plane, and is formed from a metal material such as aluminum or steel, a synthetic resin, or the like.

  The pair of extending members 6 and 6 are prismatic or prismatic members made of a metal material or the like, and are arranged on the installation surface G with a space therebetween in parallel. Each extending member 6 is fixed to the installation surface G by driving an anchor pin 63 through fixing brackets 62 arranged at appropriate intervals along the longitudinal direction. A plurality of protrusions 61 are provided on the upper surface of each extending member 6 along the longitudinal direction.

  The protrusions 61 protrude obliquely upward so as to incline in the substantially longitudinal direction of the extending member 6 with respect to the vertical direction, and extend so that the inclination directions are alternately reversed between adjacent protrusions 61. It is fixed to the output member 6 by welding or the like.

  As shown in FIG. 3, the end of the arch pipe 2 is externally fitted to the protrusion 61, so that the arch pipe 2 is fixed in an inclined state with respect to the vertical plane V. The length of the protrusion 61 is preferably such that it can be reliably fixed by insertion into the arch pipe 2. When the protrusion 61 is long, the base end side of the protrusion 61 is covered with a reinforcing plate 64 or the like. It is preferable to reinforce. Thus, as shown in FIGS. 1 and 2, a plurality of arch pipes 2 are spanned between the pair of extending members 6, 6, and each arch pipe 2 extends along the longitudinal direction of the extending members 6, 6. Arranged.

  The plurality of arch pipes 2 have the same size and shape, and are arranged so as to be alternately inclined in the opposite direction with respect to the vertical plane V orthogonal to the arrangement direction. Portions where both side portions of the arch pipes 2 and 2 which are inclined in the opposite direction intersect with each other are connected and fixed by the connecting fitting 21. As the connection fitting 21, a known fitting used for connecting pipes can be used, and examples thereof include a steel plate fitting and a steel wire fitting. In FIG. 2, illustration of some of the connecting fittings 21 is omitted.

  The top of the center of the arch pipe 2 is joined to the top of the center of the other arch pipe 2 inclined in the opposite direction, and this joint is fixed by a connecting fitting 22. In this way, a plurality of arch pipes 2 are combined to form a skeleton 4. The connection between the tops of the arch pipes 2 is not essential, and the connection may be simply made in a contact state without using the connection fitting 22.

  The sheet-like member 8 can be formed from a transparent film made of a synthetic resin such as polyvinyl chloride. The method of attaching the sheet-like member 8 to the framework 4 is not particularly limited. For example, a sheet receiving member (not shown) having a U-shaped cross section is fixed along the longitudinal direction of the framework 4 in the same manner as a conventional pipe house, The sheet-like member 8 can be fixed to the framework 4 by fitting a meandering spring member (not shown) so that the sheet-like member 8 is sandwiched between the sheet-receiving member. The sheet-like member 8 does not necessarily need to cover the entire frame 4, and may be disposed so as to cover only the upper part of the frame 4, for example.

  A top pipe 23 that passes through the top of each arch pipe 2 and supports the sheet-like member 8 is provided at the upper center of the framework 4. Further, on both sides in the longitudinal direction of the skeleton 4, straight rod-like wife posts 24 constituting the wife face are fixed by being inserted into the insertion port of the extending member 6. The end post 24 is preferably provided in an inclined state as shown in FIG. 1 in order to reduce wind resistance. The entrance / exit of the pipe house 1 is formed between a plurality of upright door pipes 25.

  In the pipe house 1 having the above-described configuration, the plurality of arch pipes 2 are arranged so as to incline in opposite directions alternately with respect to the vertical plane orthogonal to the arrangement direction, and the intersecting portions on both sides are connected by the connecting metal fittings 21. By being connected and fixed, the top portions are joined to each other, whereby a strong framework 4 can be easily configured. Further, since the outer shape of the upper portion of the skeleton 4 becomes a gentle curved shape due to the inclination of the arch pipe 2, the wind resistance received by the sheet-like member 8 stretched on the skeleton 4 can be reduced, and the skeleton 4 Can be prevented and the sheet-like member 8 can be prevented from being damaged. Furthermore, by arranging the arch pipes 2 in an inclined manner, the required number of arch pipes 2 can be reduced as compared with the case where the arch pipes 2 are arranged upright as in the prior art. As a result, the strength of the pipe house 1 can be improved while suppressing the burden of installation work and the manufacturing cost.

  If the inclination angle θ with respect to the vertical plane V of the arch pipe 2 shown in FIG. 3 is too small, it is difficult to improve the strength. On the other hand, if it is too large, it is difficult to secure the internal space of the pipe house 1 and the strength tends to decrease. The range of 30 to 60 degrees is preferable, and 45 degrees is more preferable. When the inclination angle θ is set to 45 degrees, the both sides of the arch pipes 2 and 2 are orthogonal to each other, so that the arch pipe 2 can be quickly and surely connected using the orthogonal type inexpensive connection fitting 21. Therefore, it is preferable from the viewpoint of manufacturing workability and manufacturing cost.

  In addition, as in the present embodiment, a pair of extending members 6 and 6 provided with a plurality of protrusions 61 projecting obliquely upward along the longitudinal direction extend parallel to each other along the arrangement direction of the arch pipe 2. By fixing to the installation surface G as described above, the arch pipe 2 can be easily installed at a predetermined inclination angle, so that the pipe house 1 can be installed and moved quickly and easily. In this case, since the arch pipe 2 can be installed simply by attaching the end of the arch pipe 2 to the projection 61, the installation workability of the pipe house 1 can also be improved from this point. In order for the arch pipe 2 to be securely fixed to the pair of extending members 6, 6, it is preferable that both ends of the arch pipe 2 are attached to the protrusions 61 in a state where a slight flexible deformation has occurred. . The arch pipe 2 can be fixed to the installation surface by a method of embedding both end portions of the arch pipe 2 in the ground as in the prior art.

  The number of the other arch pipes 2 whose both sides are connected to the both sides of one arch pipe 2 may be single, but the strength of the skeleton 4 can be more reliably ensured by using a plurality of them. Can be increased. However, if the number of other arch pipes 2 with respect to one arch pipe 2 is three or more, the arrangement of the arch pipes 2 becomes too dense and causes an increase in the number of parts. A configuration in which two arch pipes 2 inclined in opposite directions are connected to one arch pipe 2 is preferable.

  The pipe house of the present invention can be suitably used for agriculture and horticulture, but is not necessarily limited to this application, and can be applied to, for example, a garage or a barn.

  Further, as shown in FIG. 4, a plurality of protrusions 61 that are fitted on the ends of the arch pipe 2 are provided with different inclination angles with respect to the vertical direction, and are fixed to the extending member 6 by a reinforcing plate 64 or the like. May be. According to this configuration, the inclination angle of the arch pipe 2 can be easily adjusted by appropriately selecting the protrusion 61 to which the end of the arch pipe 2 is attached.

  Further, as shown in FIG. 5, a positioning knob 65 protruding vertically upward from the upper part of the extending member 6 is provided, and a through hole 62 a through which the knob 65 is inserted is formed in the fixing bracket 62 and fixed. You may make it prevent reliably the position shift of the extending member 6 with time.

  The pipe house of each of the above embodiments is configured such that both ends of the arch pipe 2 are attached to the protrusions 61 fixed to the pair of extending members 6, respectively, but detachably attached to the pair of extending members 6. The structure which supports the arch pipe 2 in an inclined state using the attached fixture may be sufficient. FIG. 6 is a plan view showing an example of such a fixture.

  A fixture 100 shown in FIG. 6A includes a substrate 110 and a mounting portion 120 fixed to the substrate 110. The substrate 110 is formed in a trapezoidal shape, and a plurality of attachment holes 212 are formed along the lower bottom portion so that the substrate 110 is attached to the extending member 6 in a direction in which the lower bottom portion is a lower portion. The attachment hole 212 is also formed near the upper bottom portion of the substrate 110. The mounting portion 120 is formed in a cylindrical shape so that the end portion of the arch pipe 2 is inserted therein, and is disposed so as to protrude obliquely upward in a direction in which the lower bottom portion of the substrate 110 faces downward. The inclination angle θ (see FIG. 3) of the mounting portion 120 when the lower bottom portion of the substrate 110 is horizontally disposed is not particularly limited, but is 45 ° in the present embodiment. The fixtures 100 and 200 can be made of metal, for example, and are preferably subjected to rust prevention treatment such as galvanization treatment.

  The mounting portion 120 may be fixed to the substrate 110 by welding or the like, but the mounting portion 120 can be attached to and detached from the substrate 110 using a U-bolt 122 or the like as in the present embodiment. Since it can be attached to both the front and back surfaces of the substrate 110, the direction in which the mounting portion 120 protrudes can be easily changed to enhance versatility. Moreover, you may comprise so that the inclination | tilt angle of the mounting part 120 can be adjusted by providing the insertion hole of the U volt | bolt 122 and changing the attachment angle of the U volt | bolt 122. The mounting of the arch pipe 2 to the mounting portion 120 can be performed by fitting the end portion of the arch pipe 2 to the mounting portion 120 instead of inserting the end portion of the arch pipe 2 into the internal space of the mounting portion 120.

  In the fixture 200 shown in FIG. 6B, a plurality of cylindrical mounting portions 220a and 220b are arranged symmetrically with respect to the trapezoidal substrate 210 so as to protrude in opposite directions in an inclined state. Further, it is fixed by U bolts 222a and 222b. The arrangement of the attachment holes 212 formed in the substrate 210 is the same as the attachment holes 112 of the substrate 110 shown in FIG.

  The pipe house 1 shown in FIG. 7 supports the arch pipe 2 using the fixtures 100 and 200 shown in FIG. 6 instead of providing the protrusions 61 on the pair of extending members 6 in the pipe house 1 shown in FIG. The configuration other than the fixtures 100 and 200 is the same as that of the pipe house 1 shown in FIG. The fixtures 100 and 200 shown in FIG. 7 are fixed to the outer surface sides of the pair of extending members 6 by reversing the front and back from the state shown in FIG. The method of fixing the fixtures 100 and 200 to the extension member 6 is not particularly limited. For example, the tapping bolt 66 is inserted into the attachment holes 112 and 212 of the fixtures 100 and 200 to penetrate the extension member 6 from the outer surface side. By doing so, the fixtures 100 and 200 can be fixed at arbitrary locations along the longitudinal direction of the extending member 6. In this way, after fixing the plurality of fixtures 100, 200 at predetermined positions of the extending member 6, the end portions of the arch pipe 2 are inserted into the respective mounting portions 120, 220a, 220b, whereby the pipe house 1 shown in FIG. Is completed. The lower ends of the mounting portions 120, 220a, 220b can be prevented from coming off by being closed in advance or being reduced in diameter by hitting with a hammer. The two types of fixtures 100 and 200 are not necessarily used in combination, and only one of them may be used. The fixtures 100 and 200 may be attached to the inner surface side or the upper surface side of the extending member 6 as long as interference with the arch pipe 2 is not a problem.

  As described above, by using the extending member 6 and the attachments 100 and 200 that are detachably attached to the extending member 6, the pipe house 1 can be easily carried and the assembly work and the removal work can be quickly performed. be able to. Moreover, since it is not necessary to embed the end part in the ground and to fix the arch pipe 2 as in the prior art, the arch pipe 2 can be installed on a concrete surface or the like, and the application can be expanded.

  The pair of support portions to which the fixtures 100 and 200 are detachably attached are not necessarily limited to the pair of extending members 6 as described above. For example, as shown in FIG. 8A, existing arch-shaped support pipes S arranged at intervals along one direction are fixed so as to stand upright with respect to the installation surface G. When the pipe house P exists, both end portions of the support pipe S can be used as a pair of support portions, respectively. The pipe house P has a known configuration in which central tops of a plurality of support pipes S are connected by a connector M to a purlin pipe U that extends in the arrangement direction.

  A method of reinforcing the pipe house P is as follows. First, as shown to Fig.8 (a), the fixtures 100 and 200 are attached to the both ends used as the lower part of both sides of the support pipe S from the inner side. The attachments 100 and 200 are attached to the support pipe S by, for example, inserting bolts 66 into the insertion holes formed in the support pipe S and the attachment holes 112 and 212 in the center of the attachments 100 and 200. be able to. Next, as shown in FIG. 8 (b), both ends of the arch pipe 2 are mounted on the mounting portions 120, 220a, and 220b of the fixtures 100 and 200, and the arch pipe 2 is supported, thereby supporting pipe S. The arch pipes 2 are arranged along the arrangement direction. The plurality of arch pipes 2 are arranged so as to incline in opposite directions alternately with respect to the vertical plane orthogonal to the arrangement direction, and the portions intersecting each other on both sides are connected and fixed similarly to the configuration shown in FIG. And the tops are joined together. Thus, a pipe house 1 ′ in which the pipe house P is reinforced from the inside by the plurality of arch pipes 2 is completed.

  The pipe house 1 'can be quickly and easily manufactured at low cost by effectively using the existing pipe house P. The fixtures 100 and 200 can be attached to both ends of the support pipe S from the outside, and the support pipe S may be reinforced from the outside.
