Description

[Technical Field]

[0001] The present invention relates to a reinforcing device, and more particularly to a reinforcing device for reinforcing the strength of a pipe material. [Background technology]

[0002] Greenhouses are constructed to withstand external forces by using the repulsive force of arch-shaped bent pipe materials. Therefore, the wider the opening, the greater the bending moment that occurs in the arch pipe materials, making them more likely to collapse. To counter this, it is necessary to increase the diameter of the pipe materials or add appropriate reinforcement materials.

[0003] In addition, since greenhouses are used outdoors and are exposed to strong winds and snow, they need to be strong.

[0004] Since a large amount of pipe material is used, it is important to reinforce the strength of the pipe material, and for example, a double arch structure is often used.

[0005] The double arch structure, as shown in Patent Documents 1 to 3, is constructed by placing two pipe materials in parallel and connecting the two pipe materials to provide strength reinforcement. An auxiliary tool is used for this connection (see especially Patent Document 3, Figure 2). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-22220 [Patent Document 2] Japanese Patent Application Laid-Open No. 2015-123010 [Patent Document 3] Japanese Patent Application Laid-Open No. 2016-44526 Summary of the Invention [Problem to be solved by the invention]

[0007] However, while tie bars and snow-resistant posts, which are common reinforcement methods, can be introduced inexpensively, they have the following problems. First, the load is concentrated on the area where the metal fittings are attached. Second, they can significantly reduce work efficiency depending on the usage environment. Third, there are cases where they cannot be installed at all due to the relationship with other structures or ancillary equipment.

[0008] Another problem with double arch structures made of pipe material is that two pieces of pipe material are required. This is true for new construction, but when trying to use a double arch structure made of pipe material on an already-installed greenhouse, not only do you need more pipe material, but you also need to connect the two pieces of pipe material together, which requires auxiliary tools for that connection. What's more, adjusting the connection using the auxiliary tools is time-consuming and troublesome.

[0009] Therefore, the present invention provides a reinforcing tool that does not require two pipe materials, solves the problem of cumbersome work, and solves the problem of load on the pipe materials. [Means for solving the problem]

[0010] A first aspect of the present invention is a reinforcing device for reinforcing the strength of pipe materials used in greenhouses, comprising a triangular main body, an insertion portion provided at a first vertex of the triangle for passing the pipe material through, and a first connecting portion provided at a second vertex different from the first vertex of the main body, for rotatably connecting the second vertex to one vertex of the main body of another second reinforcing device arranged adjacent to the triangular main body.

[0011] The second aspect of the present invention is the first aspect, further comprising a second connecting portion provided at a third vertex of the main body that is different from the first and second vertices, and rotatably connecting the third vertex to one vertex of the main body of yet another third reinforcing element that is arranged adjacent to the other side of the triangular main body.

[0012] In a third aspect of the present invention, in the first or second aspect, the triangular body is formed by connecting plate members corresponding to the respective sides of the triangle at their ends.

[0013] A fourth aspect of the present invention is the triangular body of the first aspect. [Effects of the Invention]

[0014] According to the present invention, the installation space is not large, the installation location can be selected arbitrarily, and the work is easy. In addition, the effect of reducing the load on the pipe (= the effect of improving the strength of the greenhouse) is significantly high, and strong reinforcement can be obtained by the true truss structure.

DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, examples of the present invention will be described with reference to the drawings, but the present invention is not limited to the following examples.

[0017] FIG. 1 is a diagram showing an example of a frame using pipe materials for a greenhouse in which reinforcing members according to an embodiment of the present invention are used in succession.

[0018] Referring to Fig. 1, in a greenhouse frame 1, a plurality of reinforcing members 5 are used for each of one pipe material 3a, one pipe material 3b, and one pipe material 3c. Twenty reinforcing members 5 are used for one pipe material 3a. Twenty reinforcing members 5 are also used for one pipe material 3b. Six reinforcing members 5 are used for one pipe material 3c.

[0019] The reinforcing element 5 has a triangular body (see also FIG. 9) described below, insertion portions through which the pipe materials 3a, 3b, and 3c are inserted, and a connecting portion that connects to an adjacent reinforcing element (see also FIG. 10).

[0020] Figure 2 is an oblique view of an example of the triangular body of the reinforcement device of Figure 1, Figure 3 is a front view of an example of the triangular body of the reinforcement device of Figure 1, Figure 4 is a back view of an example of the triangular body of the reinforcement device of Figure 1, Figure 5 is a right side view of an example of the triangular body of the reinforcement device of Figure 1, Figure 6 is a left side view of an example of the triangular body of the reinforcement device of Figure 1, Figure 7 is a plan view of an example of the triangular body of the reinforcement device of Figure 1, and Figure 8 is a bottom view of an example of the triangular body of the reinforcement device of Figure 1.

[0021] 2 to 8, the reinforcing member 5 is made up of three long boards 7a, 7b, and 7c joined at their ends to form a triangle. The three ends are connected by grommets. Furthermore, the three long boards 7a, 7b, and 7c have raised portions 9a, 9b, and 9c on the outside along their extension direction. These raised portions 9a, 9b, and 9c are intended to ensure the strength of the long boards 7a, 7b, and 7c.

[0022] Figure 9 is a diagram showing an example of an actual product corresponding to the triangular main body of the reinforcing device shown in Figures 2 to 8, and Figure 10 is a diagram showing an example of an actual product corresponding to the triangular main body of the reinforcing device shown in Figures 2 to 8, equipped with an insertion portion and a connecting portion as an auxiliary device and connected together.

[0023] Referring to FIG. 10, a first vertex 11, which is one vertex of the reinforcing element 5, is provided with an insertion portion 13 through which the pipe material 3a or the like in FIG. 1 passes. A first vertex 11a of an adjacent reinforcing element 5a is also provided with an insertion portion 13a through which the pipe material 3a or the like in FIG. 1 passes. A second vertex 15, which is another vertex of the reinforcing element 5, is provided with a first connecting portion 19 that rotatably connects to a third vertex 17a of the adjacent reinforcing element 5a. The first connecting portion 19 is constructed by overlapping and fastening the eyelet hole on the second vertex 15 side with the eyelet hole on the third vertex 17a using a bolt and nut. The same applies below. A third vertex 17, which is yet another vertex of the reinforcing element 5, is provided with a second connecting portion that rotatably connects to the second vertex of the adjacent reinforcing element on the opposite side, although this is not shown in FIG. 10. The second vertex 15a of the reinforcing element 5a is provided with a connecting portion that is rotatably connected to the third vertex of the adjacent reinforcing element.

[0024] As described above, by connecting the reinforcing members, the side opposite the first vertex through which the triangular pipe material passes is connected. This connection of the side serves as the second reinforcement in the double arch structure made up of two pipe materials. Moreover, since it can rotate in increments of the length of one side of the triangle, it provides flexibility in installation. Therefore, this reinforcing member can provide both strong reinforcement and ease of installation.

[0025] In the above embodiment, three long plates are used to form a triangular main body, but a triangular plate may also be used. The raised portion is not essential, and the necessity of the raised portion may be determined depending on the plate thickness, for example. [Explanation of symbols]
