Abstract
Description
[Technical field]
[0001] The present invention relates to a connecting jig for single-tube pipes, a pipe house, and a construction method for a pipe house. [Background technology]
[0002] Conventionally, there has been known an agricultural pipe house that is constructed by creating a framework using single-tube pipes and covering the framework with an exterior wall material of a resin film (for example, Patent Document 1). The framework is composed of single-tube pipe supports erected from the ground, and horizontal and vertical rafter pipes that connect the supports.
[0003] In order to connect single-tube pipes, connection tools such as a single-tube pipe clamp as described in Patent Document 2 or a single-tube pipe screw-fixing joint (for example, "Kanta-kun" by Joint Kogyo Co., Ltd.) that fixes single-tube pipes with insert screws are used. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Publication No. 3237392 [Patent Document 2] Japanese Patent Application Publication No. 8-82091 Summary of the Invention [Problem to be solved by the invention]
[0005] In recent years, as pipe houses have become larger, it has become necessary to use longer single-tube pipes or to connect single-tube pipes to make them longer. This results in a large load being placed on the connections between the posts, horizontal rafter pipes, and rafter pipes. In particular, with single-tube pipe clamps, the central axes of the posts and rafter pipes are not on the same plane (hereinafter, the expression "the central axes are misaligned" will be used). As a result, the posts cannot support the rafter pipes from directly below, and there is a risk of the structure being weak.
[0006] Since the angle of the connection is fixed for single-tube pipe joints, there are limitations to the design of pipe houses, and it is necessary to prepare a connection jig according to the connection part, which may lead to a lack of versatility. Fixing with screws may not provide sufficient strength to prevent the pipes from coming loose.
[0007] Therefore, an object of the present invention is to provide a connecting member for single-tube pipes, a pipe house, and a method for constructing a pipe house, which can be used to construct a large, strong pipe house. [Means for solving the problem]
[0008] In order to achieve the above object, the invention described in claim 1 comprises: A connection jig for connecting single-tube pipes used in the construction of pipe houses, etc. The method includes a connecting jig for a support that connects a horizontal rafter pipe to a support erected from the ground, and a connecting jig for a rafter pipe that connects a rafter pipe to the horizontal rafter pipe, The connecting jig for the support includes a horizontal rafter pipe fixing member, a support fixing member, and a connecting member for connecting the horizontal rafter pipe fixing member and the support fixing member, The horizontal rafter pipe fixing member includes a main body portion which is an annular member into which the horizontal rafter pipe can be inserted and fixed; The pillar fixing member is connected to the horizontal rafter pipe fixing member and includes a cylindrical main body portion that can be placed over the tip of the pillar, and a support member that is a plate-like member that is erected inside the main body portion toward the opening and is inserted into the single pipe, The rafter pipe connecting jig includes a second horizontal rafter pipe fixing member, a rafter pipe fixing member, and a connecting member that connects the second horizontal rafter pipe fixing member and the rafter pipe fixing member, The second horizontal rafter pipe fixing member has a main body which is an annular member into which the horizontal rafter pipe can be inserted and fixed; The rafter pipe fixing member is connected to the second horizontal rafter pipe fixing member and includes a cylindrical main body portion that can be placed over the end of the rafter pipe, and a support member that is a plate-like member that is erected inside the main body portion toward the opening and is inserted into the single pipe, A single pipe is inserted into the main body of the rafter pipe fixing member of the connecting jig for the support, and the single pipe is tightened and fixed toward the support member with a fixing screw through a fixing portion formed at a position corresponding to the end of the support member; A single pipe is inserted into the main body of the second rafter pipe fixing member of the rafter pipe connecting jig, and the single pipe is tightened and fixed toward the support member with a fixing screw via a fixing portion formed at a position corresponding to the end of the support member; The technical means used is to insert a horizontal rafter pipe into the connecting members of the connecting fixture for the pillar and the connecting jig for the rafter pipe, bringing them into contact with each other, and connecting them so that the central axis of the pillar and the central axis of the rafter pipe are on the same plane.
[0009] The invention described in claim 2 uses the technical means of a pipe house that is installed using a single-tube pipe, and is equipped with a body having a connection part that is connected using the connection jig described in claim 1 so that the central axis of the support and the central axis of the rafter pipe are on the same plane.
[0010] The invention described in claim 3 uses a technical measure in which the pillar on which the connection portion is formed in the pipe house described in claim 2 is the main pillar.
[0011] The invention as recited in claim 4 employs a technical measure in which the pipe house as recited in claim 3 is formed so that a solar cell module can be installed on the roof.
[0012] The invention described in claim 5 is a construction method for a pipe house installed using a single-tube pipe, which uses the technical means of using the connection jig described in claim 1 to form a structure having a connection part in which the central axis of the support and the central axis of the rafter pipe are connected so as to be on the same plane. Effect of the Invention
[0013] The central axis of the support and the central axis of the rafter pipe are connected so that they are on the same plane, that is, the central axes are not misaligned, so the support can support the rafter pipe from directly below, improving structural strength.
[0014] The connecting jig for the pillars and the connecting jig for the rafter pipes are each equipped with a support member, so that the single pipe will not deform even if it is tightly tightened with fixing screws, thereby achieving high pull-out strength.
[0015] Since the horizontal rafter pipe fixing member is formed in a ring shape, the connection angle between the support and the rafter pipe can be freely set based on the horizontal rafter pipe. Also, the rafter pipe can be extended beyond the fixed length of the single pipe, which increases the degree of freedom in the design of the pipe house.
[0016] The pipe house of the present invention has a high structural strength, so that a large, heavy object can be placed on the roof. For example, it can be suitably used for installing a solar cell module. [Brief description of the drawings]

[0018] (Connection jig) The connection jig used in the construction of the pipe house of the present invention will be described with reference to the drawings. The pipe house is installed by combining single-pipe pipes. As the single-pipe pipe, for example, a standard single-pipe pipe with a diameter of 48.6 mm, a thickness of 1.8 mm (or 2.4 mm), and a length of 6 m can be used.
[0019] When constructing the pipe house of the present invention, the connection jig S is a connection jig 1 for a support pillar. It is used in combination with a rafter pipe connection jig 2.
[0020] As shown in FIG. 1-3, the post connecting jig 1 includes a horizontal rafter pipe fixing member 10, a post fixing member 20, and a connecting member 30.
[0021] The horizontal rafter pipe fixing member 10 has an inner dimension slightly larger than the outer diameter of the horizontal rafter pipe Y and includes a main body 11 which is an annular member into which the horizontal rafter pipe can be inserted. A screw portion 11a is formed to penetrate the main body 11. Also, a fixing screw 12 is provided.
[0022] The post fixing member 20 includes a main body 21, a support member 22, and a fixing screw 23.
[0023] The main body 21 is a cylindrical member with one end sealed, and has an inner diameter slightly larger than the outer diameter of the single-tube pipe that forms the support P, so that it can be fitted over the tip of the support P. Two screw portions 21a for fixing the support P are formed through the side surface of the main body 21 at positions corresponding to the ends of the support member 22.
[0024] The support member 22 is a plate-like member erected from the bottom 21b inside the main body 21 toward the opening, and is formed with a width slightly smaller than the inner diameter of the support P. When the main body 21 is placed over the tip of the support P, the support member 22 is inserted into the support P from the opening.
[0025] The connecting member 30 is a member that connects the horizontal rafter pipe fixing member 10 and the pillar fixing member 20. The connecting member 30 is erected from the upper part of the pillar fixing member 20, and is connected so that the horizontal rafter pipe fixing member 10 is positioned on the central axis of the pillar fixing member 20. In other words, when the pillar connecting jig 1 is connected to the pillar, the horizontal rafter pipe fixing member 10 is positioned on the central axis of the pillar P.
[0026] As shown in FIG. 4-6, the rafter pipe connecting jig 2 includes a horizontal rafter pipe fixing member 40, a rafter pipe fixing member 50, and a connecting member 60.
[0027] The horizontal rafter pipe fixing member 40 has the same structure as the horizontal rafter pipe fixing member 10 of the post connection jig 1, so a description thereof will be omitted. For the correspondence of the symbols, please refer to the explanation of the symbols.
[0028] The rafter pipe fixing member 50 has the same structure as the pillar fixing member 20 of the pillar connection jig 1 if the pillar P is replaced with the rafter pipe T, so a description thereof will be omitted. For the correspondence of the symbols, please refer to the explanation of the symbols.
[0029] The connection member 60 is a member that connects the horizontal rafter pipe fixing member 40 and the rafter pipe fixing member 50. The connection member 60 is formed to a dimension that does not interfere with the connection member 30 of the connection jig for the support 1 when connecting the single-tube pipe. The connection member 60 connects the horizontal rafter pipe fixing member 40 and the rafter pipe fixing member 50 so that the central axis of the horizontal rafter pipe fixing member 40 and the central axis of the support fixing member 20 are located on the same plane when the horizontal rafter pipe fixing member 10 (main body portion 11) of the connection jig for the support 1 abuts the horizontal rafter pipe fixing member 40 (main body portion 41) of the connection jig for the rafter pipe 2. In other words, when the rafter pipe T is connected to the horizontal rafter pipe Y by the connection jig for the rafter pipe 2, the central axis of the support P and the central axis of the rafter pipe T are located on the same plane.
[0030] (How to connect single pipes) A method for connecting the pole connecting jig 1 to the pole will be described with reference to FIG.
[0031] First, the pillar connection jig 1 is placed over the pillar P, and the end of the jig is butted against the bottom 21b. At this time, the main body 21 is placed over the exterior of the pillar, and the support member 22 is inserted inside. In other words, there is an area of the wall of the pillar sandwiched between the main body 21 and the support member 22.
[0032] Next, the outer surface of the support pillar P is fastened with the fixing screws 23 from the screw portions 21a in two places. Here, the screw portions 21a are formed at positions corresponding to the ends of the support members 22. As a result, even if the support pillar P is firmly fastened with the fixing screws 23, the support pillar P will not deform because it is supported from the inside by the support members 22.
[0033] The conventional fixing method was to tighten the single pipe with a set screw to prevent it from coming loose. However, tightening the set screw deforms the single pipe, making it thinner the further into the jig it goes, so the effect of preventing it from coming loose was weak. With the support post connection jig 1, even if the support post P is firmly tightened with the fixing screw 23, the support post P does not deform, so the support post can be firmly fixed.
[0034] (Connection method of posts, horizontal rafter pipes and rafter pipes) The connection jig S of the present invention is used for connection parts in three directions, namely, the support P, the horizontal rafter pipe Y, and the rafter pipe T. Hereinafter, a method for connecting a single pipe to the connection part will be described with reference to the drawings.
[0035] Here, we will explain how to connect the horizontal rafter pipes and rafter pipes to the main pillar in the center and the two center pillars adjacent to the main pillar, that is, the horizontal rafter pipe Y is the ridge pipe, at the top of the roof. Note that the connection method from the main pillar to the center pillar is the same, so only the connection method to the center pillar on one side will be explained.
[0036] First, the pillar connection jig 1 is placed over the tip of the main pillar P and the center pillar, and the pillar connection jig 1 is fixed to the pillar using the connection method described above.
[0037] Next, the single pipe for the horizontal rafter pipe is inserted into the connecting jig for the support 1 to form the horizontal rafter pipe Y. At this time, as shown in Figs. 8 and 9, two connecting jigs for rafter pipes 2A and 2B are arranged sandwiching the connecting jig for the support 1. The horizontal rafter pipe fixing member 40 (main body 41) of the connecting jig for the rafter pipe 2 is abutted against the horizontal rafter pipe fixing member 10 (main body 11) of the connecting jig for the support 1 and arranged sandwiching them. As a result, the central axis L of the connecting jig for the support 1, the central axis M of the connecting jig for the rafter pipe 2A, and the central axis N of the connecting jig for the rafter pipe 2B are placed on the same plane. Here, the central axis L of the connecting jig for the support 1 is the central axis of the main body 21 of the fixing member 20 for the support, and coincides with the central axis in the axial direction of the support P. Similarly, the central axis M of the rafter pipe connecting jig 2A and the central axis N of the rafter pipe connecting jig 2B are the central axes of the main body 51 of the rafter pipe fixing member 50, and coincide with the central axis in the axial direction of the rafter pipe T. Similarly, a horizontal rafter pipe Y, a connecting jig for a support 1, and two connecting jigs for rafter pipes 2 are arranged on the center column.
[0038] Next, one end of the rafter pipe T is inserted into the rafter pipe fixing member 50 of the rafter pipe connecting jig 2 for the support, and the other end is inserted into the rafter pipe fixing member 50 of the rafter pipe connecting jig 2 for the second support, and fixed against the bottom 52b.
[0039] Next, while maintaining the horizontal rafter pipe fixing member 40 (main body 41) of the rafter pipe connecting jig 2 abutting against the horizontal rafter pipe fixing member 10 (main body 11) of the connecting jig for pillar 1, the connecting jig for pillar 1 is fixed to the horizontal rafter pipe Y with the fixing screw 12, and the connecting jigs for rafter pipes 2A, 2B are each fixed to the horizontal rafter pipe Y with the fixing screw 23. The same is true for the center pillar. As a result, the rafter pipe T is fixed to the pillar P and the horizontal rafter pipe Y, as shown in Figure 10 (part A in the figure).
[0040] The central axes of each connection jig (central axis L of connection jig for pillars 1, central axis M of connection jig for rafter pipes 2A, and central axis N of connection jig for rafter pipes 2B) are on the same plane, so they are connected so that the central axis of pillar P and the central axis of rafter pipe T are on the same plane. In other words, since the central axes are not misaligned, pillar P can support rafter pipe T from directly below, improving structural strength.
[0041] In a similar process, the horizontal rafter pipes Y and the rafter pipes T can be connected to the center columns and between the center columns and side columns. As a result, as shown in Figure 11 (part B in the figure), the rafter pipes T can be connected and extended to form the framework of a large pipe house H.
[0042] By including such a process, for example, a structure having a sloping roof on both sides as shown in Fig. 12 can be created, and the structure can be covered with a resin film exterior wall material to create an agricultural pipe greenhouse. Since no protrusions are formed on the roof, there is no risk of the exterior wall material getting caught and damaged, or sagging and pooling water.
[0043] Using the pipe house construction method of the present invention, pipe houses of various shapes can be constructed. For example, a pipe house with a roof that is inclined on only one side or a pipe house with a convex roof by changing the angle when connecting the rafter pipes T can be constructed.
[0044] The pipe house of the present invention has a high structural strength, so large, heavy objects can be placed on the roof. For example, a solar cell module can be installed on the roof of an agricultural vinyl house. This allows agriculture and power generation to be carried out in one place, making it ideal for effective land use.
[0045] The pillar connection jig 1 and the rafter pipe connection jig 2 can rotate around the horizontal rafter pipe Y, so the connection angle between the pillar P and the rafter pipe T can be freely set. Also, the rafter pipe T can be extended beyond the standard length of a single pipe. This allows for greater freedom in the design of pipe houses.
[0046] (Effects of the embodiment) According to the present invention, the central axis of the pillar P and the central axis of the rafter pipe T (central axis L of the pillar connecting jig 1, central axis M of the rafter pipe connecting jig 2A, and central axis N of the rafter pipe connecting jig 2B) are connected so as to be on the same plane. In other words, since the central axes are not misaligned, the pillar P can support the rafter pipe T from directly below, thereby improving the structural strength.
[0047] The connection jig 1 for the support and the connection jig 2 for the rafter pipe each have a support member, so that even if the single pipe is tightly tightened with a fixing screw, the single pipe will not deform and high pull-out strength can be obtained.
[0048] Since the horizontal rafter pipe fixing member 10 and the horizontal rafter pipe fixing member 40 are formed in an annular shape, the connection angle between the support P and the rafter pipe T can be freely set based on the horizontal rafter pipe Y. Also, since the rafter pipe T can be extended beyond the fixed length of the single pipe, the degree of freedom in designing the pipe house can be increased.
[0049] Furthermore, since there are no protruding parts on the roof surface or attic, they do not get in the way when covering the pipe house with vinyl, installing a mounting base for solar cell modules on the outside, or installing electrical equipment or air conditioning equipment on the inside.
