Hereinafter, embodiments of the pipe packing system according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a diagram showing a state in which a plurality of metal pipes 10 (steel pipe materials, etc.) are bundled and fixed by using the pipe packing system 1 according to the present invention. As shown in the figure, the pipe packing system 1 is composed of a support member 2 (2a to 2c), a connecting material 3, a stopper 4, a cover material 5, and an end cap 6 (6a, 6b).

The support member 2 is composed of a metal square pipe (flat pipe) having a rectangular contour in a cross section orthogonal to the longitudinal direction, and in the present embodiment, the support member 2 has three supports as shown in FIG. The members (the uppermost support member 2a, the middle support member 2b, and the lowermost support member 2c) are used so as to be held in the horizontal direction. As shown in FIG. 2, bolt insertion holes 21 penetrating in the vertical direction are formed at both ends of the uppermost support member 2a and the lowermost support member 2c, respectively. Further, notches 22 are formed at the center positions in the width direction at both ends of the support member 2b in the middle stage.

A reinforcing material 23 (see FIG. 2) is inserted inside the support members 2a and 2c. The reinforcing member 23 is a short metal joint 23b in which two metal rod-shaped members 23a having the same length as the support members 2a and 2c are arranged side by side at predetermined intervals and arranged between them, respectively. They are connected by welding, and are arranged inside the support members 2a and 2c (center position in the width direction) as shown in the cross-sectional view of FIG.

Reinforcing plates 23c are fixed to both ends of the reinforcing material 23. A bolt insertion hole 23d is formed in the reinforcing plate 23c at a position overlapping the bolt insertion holes 21 of the support members 2a and 2c. When the support members 2a and 2c are connected to each other by using the connecting member 3 shown in FIG. 1, the reinforcing plate 23c is deformed inward around the bolt insertion hole 21 due to the tightening force of the connecting member 3. This is to prevent this. Since the tightening force of the connecting member 3 acts on the upper surface side of the uppermost support member 2a and acts on the lower surface side of the lowermost support member 2c, the tightening force of the connecting member 3 acts on the lower surface side of the uppermost support member 2a. The reinforcing plate 23 is inserted in the direction in which the reinforcing plate 23c is on the upper side (the direction in which the top and bottom of the reinforcing material 23 shown in FIG. 2 is reversed), and the reinforcing plate 23c is inserted with respect to the lowermost support member 2c. The reinforcing material 23 is inserted in the downward direction (the same direction as the reinforcing material 23 shown in FIG. 2).

On the other hand, the reinforcing member 24 (see FIG. 2) is inserted inside the support member 2b. The reinforcing material 24 has almost the same structure as the reinforcing material 23 inserted in the support members 2a and 2b, but is different from the reinforcing material 23 in that the reinforcing plate 23c is not fixed. The reinforcing member 24 is also arranged inside the support member 2b (at the center position in the width direction).

The connecting member 3 is for connecting and fixing both ends of the three support members 2a to 2c, and in the present embodiment, as shown in FIG. 1, a bolt 31 (stud bolt) and a nut. It is composed of 32. The diameter of the bolt insertion holes 21 (see FIG. 2) of the support members 2a and 2c is set to be slightly larger than the diameter of the bolt 31.

The stopper 4 is made of a flexible synthetic resin, and is composed of an upper portion 42, a middle portion 43, and a lower portion 44, as shown in FIG. 4 (2). The upper portion 42 and the lower portion 44 have a basic shape such that a lateral triangular prism is removed from a rectangular parallelepiped, and the middle portion 43 has a through hole 45 penetrating in the horizontal direction in the center. The through hole 45 of the middle stage portion 43 corresponds to the contour shape of the cross section (cross section orthogonal to the longitudinal direction) of the support member 2 (see FIGS. 1 and 2), and the support member 2 can be inserted without difficulty. It is formed to a size that allows the stopper 4 to be mounted on the outer peripheral portion of the support member 2 exactly.

An upward tapered portion 42c is formed in the upper portion 42 at a position above one opening 45a of the through hole 45, and the upper portion 42 is scooped downward from the upper surface portion 42b to reach a position near the through hole 45. The plurality of cutting portions 42a and the plurality of cutting portions 42a cut inward from the upward tapered portion 42c are formed so as to be parallel to each other in the width direction of the stopper 4. Further, in the lower portion 44, a downward tapered portion 44c is formed at a position below one opening 45a of the through hole 45, and a downward tapered portion 44c is formed, and the lower portion 44 is scooped upward from the lower surface portion 44b to a position near the through hole 45. A plurality of cutting portions 44a reaching up to and a plurality of cutting portions 44a cut inward from the downward tapered portion 44c are formed so as to be parallel to each other in the width direction of the stopper 4.

These hollows 42a and 44a give the stopper 4 made of synthetic resin an appropriate flexibility, and as a result, the pipe 10 (see FIG. 1) can be suitably held, and only by the volume thereof. The amount of synthetic resin raw material used can be reduced. In the present embodiment, the hollow portion 42a is formed inward from the upper surface portion 42b and the upward tapered portion 42c, and the hollow portion 44a is formed inward from the lower surface portion 44b and the downward tapered portion 44c. However, it may be formed inward from any other surface (outer surface).

The cover material 5 is formed by molding a synthetic resin into a square cylinder (see FIG. 5), and the inside of the cylinder is a cross section (cross section orthogonal to the longitudinal direction) of the support member 2 (see FIGS. 1 to 3). It is set to a dimension that corresponds to the contour shape and allows the support member 2 to be easily inserted (a dimension that can be just mounted on the outer peripheral portion of the support member 2).

The end caps 6 (6a, 6b) are used by being attached to both ends of the support member 2 (see FIGS. 1 and 2). More specifically, the end cap 6a shown in FIGS. 6 (1) and 6 (2) is attached to both ends of the uppermost support member 2a and the lowermost support member 2c, and is the support member 2a or the support member. The shape and dimensions are set so that the end of 2c can be covered as a whole, and the bolt insertion hole 21 formed at the end of the support member 2a or the support member 2c when mounted (see FIG. 2). A bolt insertion hole 61 is formed at a position corresponding to the above.

On the other hand, the end caps 6b shown in FIGS. 6 (3) and 6 (4) are attached to both ends of the support member 2b (see FIGS. 1 and 2) in the middle stage, and the ends of the support member 2b as a whole. The notch 62 is formed at a position inside the notch 22 (see FIG. 2) formed at the end of the support member 2b when the support member 2b is mounted, while being set to a shape and dimensions that can be covered with the support member 2b. Has been done. The width dimension of the notch 62 is set to be slightly larger than the diameter of the bolt 31 (see FIG. 1).

Here, to explain how to use the pipe packing system 1 according to the present invention, first, as shown in FIG. 7, the support member 2 is inserted into the through hole 45 of the stopper 4 and the inside of the cylinder of the cover material 5, and the stopper is stopped. 4 and the cover material 5 are attached to the outer peripheral portion of the support member 2.

The stopper 4 and the cover material 5 are provided on both the left and right sides of one cover material 5 so that the upward tapered portion 42c and the downward tapered portion 44c are both inside (cover material 5 side). By arranging and combining them one by one, it functions as a set of pipe holding means 7 (see FIG. 7), and has the same number of pipes as the pipes 10 (see FIG. 1) arranged in parallel in the horizontal direction to be supported by the support member 2. The holding means 7 is attached to each support member 2 (support members 2a to 2c shown in FIG. 1). That is, as shown in FIG. 1, when three pipes 10 are to be supported in parallel in the horizontal direction, three sets of pipe holding means 7 are attached to one support member 2.

Further, as shown in FIG. 8, end caps 6a are attached to both ends of the uppermost support member 2a and the lowermost support member 2c, and end caps 6b are attached to both ends of the middle support member 2b, respectively. Mounting. Then, the end caps 6a and 6b are fixed to the ends of the support members 2a to 2c by any fixing means (for example, bolts and nuts, clamps, etc.) (not shown).

Next, as shown in FIG. 9, two support members 2c (lowermost support members) to which the stopper 4, the cover material 5, and the end cap 6a are attached are arranged in parallel at appropriate intervals. The pipe 10 is placed at an appropriate position above them (more specifically, the position above each cover material 5, the position indicated by the broken line in FIG. 9), and the vicinity of both ends of the pipe 10 is the two support members. It shall be in a state of being supported by 2c respectively.

Subsequently, the middle support member 2b to which the stopper 4, the cover material 5 and the end cap 6b are attached is placed on the lowermost support member 2c and the pipe 10, and the pipe 10 and the stopper are further placed on them. 4. The cover material 5 and the uppermost support member 2a to which the end cap 6a is attached are placed in order. Then, as shown in FIG. 1, the uppermost support member 2a and the lowermost support member 2c are connected by a connecting member 3 (bolts 31 and nuts 32).

To connect the uppermost support member 2a and the lowermost support member 2c by the connecting member 3, the bolts 31 are inserted into the bolt insertion holes 21 (see FIG. 2) formed at both ends thereof. This is done by tightening the nuts 32 attached to both ends of the bolt 31. Further, regarding the support member 2b in the middle stage, the inner region of the notch 22 (see FIG. 2) formed at both ends (and the notch 62 (see FIG. 6) of the end cap 6b mounted on the support member 2b). Is in a state where the bolt 31 passes through.

Then, as shown in FIG. 1, each pipe 10 is firmly attached (at six points) by the support members 2 (cover material 5) above and below the pipes 10 and the four stoppers 4 attached to the support members 2 respectively. A plurality of pipes 10 can be suitably bundled and fixed without being supported and causing rattling or misalignment. Further, since the cover material 5 made of synthetic resin is attached to the support member 2, it is possible to suitably avoid damage to the surface of the pipe 10 due to contact between the metal materials.

Further, the pipe packing system 1 according to the present invention can be manufactured at an extremely low cost as compared with the conventional pipe packing equipment. To explain this point concretely, as described above, the composite support member constituting the conventional packing equipment for pipes requires the production of a complicated mold at the time of manufacturing, and one molding is performed by one molding process. Since only products can be obtained, the manufacturing cost per product increases, but both are general-purpose products (as the support member 2 and the connecting material 3 constituting the pipe packing system 1 according to the present invention). (Flat pipes, bolts, and nuts) can be used, and since the stopper 4 and the cover material 5 both have a simple shape, it is not necessary to use a complicated mold for molding, and it is extremely. It can be manufactured easily and efficiently. Therefore, the pipe packing system 1 according to the present invention can be manufactured at an extremely low cost as compared with the conventional product.

As an embodiment of the pipe packing system 1 according to the present invention, an example of bundling and packing a total of six pipes (three rows in a row and two steps in a vertical direction) is shown in FIG. And / or by stacking more middle support members 2b between the support members 2a, 2c, it is possible to bind and pack a larger number of pipes 10. Further, by selecting a smaller or larger size stopper 4 and a cover material 5, it can be applied to a pipe having a diameter different from that of the pipe 10 shown in the figure.

Further, it supports means (for example, bolts and nuts, clamps, etc.) (not shown) for preventing the stopper 4 or the cover material 5 mounted on the support member 2 from moving in the longitudinal direction of the support member 2. It can also be applied to the member 2, the stopper 4, or the cover material 5.
