Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, it is difficult to arrange insertions such as pipes and futon cages as per the design drawings, and they will inevitably shift from the designed positions. Therefore, generally, a futon cage without an opening for passing the insertion is brought to the site, and so-called on-site fitting is often performed, that is, a hole-opening operation is carried out on-site according to the actual position of the insertion.

[0005] An object of the present invention is to provide a futon cage capable of coping with positional deviation on-site.

Means for Solving the Problems

[0006] The futon cage of the present invention includes a cage body 10 having an opening 11a1 on the front surface for protruding the tip of an insert 110 passing through the interior to the outside, and restraining members 20, 20A attached to the opening 11a1 for suppressing the outflow of the stuffing material 30 from the gap between the insert 110 and the opening 11a1, and is characterized in that the restraining members 20, 20A have insertion holes 22a for inserting the insert 110.

[0007] Preferably, in the futon cage 1, the restraining members 20, 20A include a net body 21 attached to the opening 11a1. Further, preferably, the restraining members 20, 20A include an annular body 22 attached to the outer periphery of the insert 110, and the net body 21 is attached to the outer periphery of the annular body 22.

[0008] Also, preferably, the restraining member 20 is smaller than the opening 11a1.

[0009] Alternatively, preferably, the restraining member 20A is larger than the opening 11a1. In this case, preferably, the restraining member 20A is overlapped with the front surface of the cage body 10 from the inside.

[0010] The construction method of the futon cage of the present invention includes a step of opposing the back surface of the cage body 10 having an opening 11a1 on the front surface for protruding the tip of an insert 110 passing through the interior to the outside to the slope 100, a step of attaching restraining members 20, 20A having insertion holes 22a for inserting the insert 110 to the opening 11a1 for suppressing the outflow of the stuffing material 30 from the gap between the insert 110 and the opening 11a1, and a step of filling the cage body 10 with the stuffing material 30.

[0011] In addition, another futon cage construction method of the present invention includes a step of installing the cage body 10 on the slope 100, a step of providing an opening 11a1 on the front surface of the installed cage body 10 for protruding the tip of the insert 110 passing through the inside to the outside, and a step of installing the restraining members 20, 20A for suppressing the outflow of the filling material 30 from the gap between the insert 110 and the opening 11a1, which have insertion holes 22a for inserting the insert 110, on the opening 11a1, and a step of filling the cage body 10 with the filling material 30.

Advantages of the Invention

[0012] In the futon cage and construction method of the present invention, even if the size of the opening is made larger than the insert considering displacement, the outflow of the filling material can be suppressed by the restraining member. Further, when an opening is provided in the cage body in advance, on-site drilling work is unnecessary. When providing an opening on-site, drilling can be accurately performed according to the position of the insert.

[0013] In the above futon cage, when the restraining member includes a net body attached to the opening, the restraining member can be made to fit with the cage body also composed of a net. Further, when the restraining member includes an annular body attached to the outer periphery of the insert and a net body is attached to the outer periphery of the annular body, the outflow of the filling material can be further suppressed.

[0014] Further, when the restraining member is smaller than the opening, the restraining member can be passed through the opening, and for example, the work of positioning the restraining member on the back side of the front surface of the cage body can be easily performed, etc., improving workability.

[0015] When the restraining member is larger than the opening, by overlapping the restraining member on the front surface of the cage body from the inside, the pressure received by the restraining member from the filling material can be transmitted to the cage body, simplifying the fixing of the restraining member to the cage body.

Embodiments for Carrying Out the Invention

[0017] Next, an embodiment of the futon cage 1 of this invention will be described in detail with reference to the drawings. As shown in FIGS. 1, 2, and 4, the futon cage 1 of this invention includes a cage main body 10 having an opening (first opening) 11a1 on the front surface for protruding the tip of an insertion member 110, such as a drain pipe, passing through the inside of the futon cage 1 to the outside, and a suppression member 20 attached to the first opening 11a1 to suppress the outflow of the stuffing material 30 from the gap between the insertion member 110 and the first opening 11a1.

[0018] First, the cage main body 10 will be described. The cage main body 10 is substantially box-shaped. The cage main body 10 includes a front net 11 that constitutes the front surface and the front half of the bottom surface of the cage main body 10, a rear net 12 that constitutes the rear surface and the rear half of the bottom surface of the cage main body 10, a pair of side nets 13 that constitute the side surfaces of the cage main body 10, a lid net 14 (see FIG. 2) that closes the upper opening of the box body B formed by connecting the front net 11, the rear net 12, and the side nets 13, and a connecting tool (for example, a coil: not shown) for connecting each net. Further, the cage main body 10 may be reinforced with stays connecting the front and rear, and the rear and bottom surfaces.

[0019] The dimensions of the cage body 10 are as follows: the length (width) in the left - right direction is, for example, 1000 - 3000 mm, particularly 2000 mm; the length (depth) in the front - rear direction is, for example, 800 - 1500 mm, particularly 1200 mm; and the height is, for example, 300 - 800 mm, particularly 500 mm.

[0020] The front net 11, rear net 12, side nets 13, and lid net 14 are all made of welded wire mesh and have vertical wires V and horizontal wires H (see Fig. 3B). For the front net 11, the pitch of the vertical wires V is smaller than the pitch of the horizontal wires H and is set to 1 / 3 or less. Specifically, the pitch of the vertical wires V is, for example, 20 mm, and the pitch of the horizontal wires H is, for example, 75 mm. The rear net 12 and side nets 13 can have the same pitch as the front net 11. However, it is not necessarily required to have the same pitch, and it can be changed as appropriate. Both the vertical wires V and horizontal wires H are metal wires, particularly zinc - aluminum alloy - plated iron wires. The wire diameter is, for example, 4 mm or more.

[0021] In the front net 11, the vertical wire V is bent in a substantially L - shape and includes a vertical net portion 11a and a bottom net portion 11b. Similarly, in the rear net 12, the vertical wire V is bent in a substantially L - shape and includes a vertical net portion 12a and a bottom net portion 12b. Then, while butting the tip of the bottom net portion 11b of the front net 11 and the tip of the bottom net portion 12b of the rear net 12, and connecting them to each other with a connector, a groove body substantially U - shaped in side view is formed. The box body B is formed by closing both side surfaces of the groove body with the side nets 13.

[0022] Incidentally, the first opening 11a1 is provided in the vertical net portion 11a of the front net 11. Its shape is a substantially rectangular shape that is long in the vertical direction when viewed from the front side. Its size is at least larger than the diameter of the insertion object 110. Preferably, it is 1.5 times or more the diameter of the insertion object 110, and more preferably 2 times or more. Also, it is larger than at least one of the pitches of the vertical line V and the horizontal line H, preferably both. That is, the first opening 11a1 is not a mesh but an intentionally provided opening. Such an opening can be formed by removing the portion corresponding to the first opening 11a1 after forming the net by combining the vertical line V and the horizontal line H, or by combining the vertical line V and the horizontal line H with a length that takes the first opening 11a1 into consideration in advance. As shown in FIG. 2, the first opening 11a1 is provided at a position shifted to one side (left side) from the center in the left-right direction of the front net 11 when viewed from the front side. Also, it is provided at a position shifted downward from the center in the vertical direction. The periphery (top, bottom, left, and right) of the first opening 11a1 is not open over the entire circumference.

[0023] Also, in the vertical net portion 12a of the back net 12, an opening (second opening) 12a1 is provided for protruding the rear end of the insertion object 110 from the futon cage 1 or protruding the embedded object 120 (see FIG. 4) described later into the futon cage 1. This second opening 12a1 is, like the first opening 11a1, a substantially rectangular shape that is long in the vertical direction when viewed from the front side. The size of the second opening 12a1 is not particularly limited as long as it is larger than at least the diameter of the insertion object 110. The second opening 12a1 is provided above the first opening 11a1 in order to match the insertion object 110 that slopes upward (for example, a 5-degree drainage slope) toward the rear.

[0024] Next, the suppression member 20 will be described. As shown in FIG. 3B, the suppression member 20 is smaller than the first opening 11a1 and can pass through the first opening 11a1 without tilting the suppression member 20 with respect to the vertical net portion 11a. This suppression member 20 includes a net body 21 and an annular body 22.

[0025] The net body 21 is made of a welded wire mesh and, as shown in Fig. 3A, includes vertical wires V and horizontal wires H. Both the vertical wires V and the horizontal wires H are metal wires, particularly zinc-aluminum alloy-plated iron wires. The wire diameter is, for example, 4 mm or more. The pitch of the vertical wires V and the pitch of the horizontal wires H of the net body 21 are the same as or smaller than those of the front net 11. Also, the pitch of the vertical wires V is smaller than the pitch of the horizontal wires H. It is preferable that the net body 21 has the same material and wire diameter as the cage body 10 and the same or smaller pitch, so that it has durability equal to or better than that of the cage body 10.

[0026] When viewed from the front side, the net body 21 has a substantially rectangular shape. Its size is smaller than that of the first opening 11a1. Here, the size of the first opening 11a1 is not limited to the innermost dimension. That is, since both the front net 11 and the net body 21 are nets, for example, even if the vertical wires V interfere with each other, they can be shifted left and right by the thickness of the vertical wires V so that they no longer interfere with each other, and the net body 21 can be passed through the first opening 11a1. Therefore, when the tips of the vertical wires V and the horizontal wires H of the front net 11 protrude toward the first opening 11a1 side, as long as the protruding part does not interfere with the horizontal wires H and the vertical wires V of the net body 21 that are perpendicular to the protruding part, the dimension obtained by ignoring the protruding part is taken as the size of the first opening 11a1.

[0027] The net body 21 is provided with holes 21a that are slightly larger than the outer diameter of the inserted object 110. These holes 21a are larger than at least either the pitch of the vertical wires V or the horizontal wires H, preferably both. That is, the holes 21a are not mesh openings but intentionally provided openings. Such openings can be formed by removing the portion corresponding to the holes 21a after forming the net by combining the vertical wires V and the horizontal wires H, or by using vertical wires V or horizontal wires H with lengths that take the holes 21a into account in advance. The periphery (top, bottom, left, and right) of the holes 21a is not open over the entire circumference.

[0028] The annular body 22 is a packing made of, for example, synthetic rubber. It is substantially donut-shaped or substantially cylindrical, and the central hole serves as an insertion hole 22a for inserting the insert 110. The diameter of the insertion hole 22a is, for example, 100 mm (when the insert 110 is a PV pipe with a diameter of φ75). This annular body 22 is attached to the holes 21a of the net body 21. In this state, it can also be said that the net body 21 is attached to the outer periphery of the annular body 22. The annular body 22 covers the tips of the vertical lines V and horizontal lines H of the net body 21 on the side of the holes 21a.

[0029] Next, based on FIG. 4, the construction method of the futon cage 1 will be described.

[0030] First, the cage body 10 having the first opening 11a1 is installed on the stepped slope 100 (cage body installation step: S1). In the case of multi-stage stacking, after constructing the lower futon cage, the cage body 10 is installed on top of it. For example, in the case of a 4-stage stack, since the buried object 120 such as a drain pipe is provided in the part corresponding to the third stage from the bottom, the cage body 10 having the first opening 11a1 is installed in the third stage. Also, the back surface of the cage body 10 is opposed to the slope 100, and it is installed so that the second opening 12a1 is aligned with the position of the buried object 120.

[0031] Next, the insert 110 is connected to the buried object 120 (insert connection step: S2). At this time, the insert 110 is passed through the first opening 11a1, and the tip is projected outside from the first opening 11a1. The rear end is connected to the buried object 120 using the second opening 12a1. In the case of the conventional futon cage 1 without the first opening 11a1 and the second opening 12a1, a drilling operation is required here, but in the futon cage 1 of the present invention, since the first opening 11a1 and the second opening 12a1 are provided in advance, the drilling operation is unnecessary and the workability is good.

[0032] Next, attach the restraining member 20 to the outer periphery of the insert 110. Specifically, pass the insert 110 through the annular body 22. At this time, if a plurality of types of restraining members 20 with different diameters of the annular body 22 (holes 21a of the mesh body 21) are prepared, the cage body 10 can be used for inserts 110 with different diameters while using the same one. Also, if a blocking member formed by not providing holes 21a in the mesh body 21 is prepared, the same cage body 10 can be used for the part without the insert 110.

[0033] The front and rear positions of the restraining member 20 are adjusted so that the mesh body 21 is substantially flush with the vertical net portion 11a of the front net 11. When viewed from the front side, if the mesh body 21 is displaced with respect to the first opening 11a1 and a part of the mesh body 21 overlaps the vertical net portion 11a, it is preferable to arrange the mesh body 21 on the rear side of the vertical net portion 11a. Although pressure from the packing material 30 is also applied to the mesh body 21, if the mesh body 21 overlaps the vertical net portion 11a from the rear, the pressure can be borne by the vertical net portion 11a, and the forward movement of the restraining member 20 can be suppressed.

[0034] After adjusting the position, fix the mesh body 21 to the vertical net portion 11a (restraining member attachment step: S3). The fixing means 40 is, for example, a binding wire as shown in FIG. 3B. By tying the binding wire so as to straddle the vertical lines V of the front net 11 and the mesh body 21 and also so as to straddle the horizontal lines H of the front net 11 and the mesh body 21, it can support the pressure from the packing material 30, and the binding wire functions as a substitute for the horizontal line H and the vertical line V, and the outflow of the packing material 30 from the gap can be suppressed.

[0035] Next, fill the cage body 10 with the packing material 30 (filling step: S4). The packing material 30 is so-called crushed stone. Specifically, it is No. 1 to No. 4 of single-sized crushed stone, and No. 4 is particularly preferable. However, it is not limited to crushed stone, and as long as it is an object of a size that does not pass through the mesh, natural stone may be used, or an object heavier than water such as concrete or bricks may be used.

[0036] Finally, attach the lid net 14, and the construction of the futon cage 1 is completed.

[0037] Next, a modified example of the restraining member will be described. This restraining member 20A is larger than the first opening 11a1. Specifically, it is larger than the first opening 11a1 in either the vertical direction or the horizontal direction. However, as shown in FIG. 5, it is preferably larger than the first opening 11a1 in both the vertical and horizontal directions. In this way, when the restraining member 20A is larger than the first opening 11a1, the outer edge of the restraining member 20A can be overlapped with the vertical netting portion 11a from the inside of the cage body 10, and the pressure received by the restraining member 20A from the filling material 30 can be borne by the vertical netting portion 11a, making it easier to fix the restraining member 20A to the cage body 10. The fixing means 40 may be a binding wire or a coil. Also, when the lower end of the restraining member 20A is in contact with the bottom surface of the cage body 10, it may not be particularly fixed.

[0038] The restraining member 20A may be entirely composed of a plate material such as a metal plate. Even in this case, the outflow of the filling material 30 from the gap between the first opening 11a1 and the inserted object 110 can be suppressed. Note that the plate material includes those provided with only the insertion hole 22a, those provided with a hole for passing the fixing means 40 in addition to the insertion hole 22a, and those provided with a water-permeable hole in addition to the insertion hole 22a and the hole for the fixing means 40. For example, punching metal and expanded metal are also included in the plate material.

[0039] When the restraining member 20A is composed of a net body 21 and an annular body 22, as the annular body 22, it is preferable to use one in which an insertion hole 22a is provided in a metal plate, specifically, a circular or polygonal metal plate provided with an insertion hole 22a. If this annular body 22 is welded to the net body 21, a restraining member 20A with good appearance and excellent durability can be obtained. Also, if the welded portion is located on the back side of the annular body 22, that is, inside the cage body 10, the welded portion will not be exposed on the front surface, and the appearance will be even better.

[0040] Next, a construction method of the futon cage 1 when providing the first opening 11a1 on-site will be described with reference to FIG. 6.

[0041] First, place the cage body 10 without the first opening 11a1 on the stepped slope 100 (cage body installation step: S11). At this time, the back surface of the cage body 10 faces the slope 100. Also, the cage body 10 may be placed slightly shifted forward from its original installation position.

[0042] Next, connect the insertion member 110 to the embedded object 120 (insertion member connection step: S12). If the second opening 12a1 is required, it may be provided in advance or at this stage. Attach a suppression member 20A to the outer periphery of the connected insertion member 110. Thereby, even if the suppression member 20A is larger than the first opening 11a1, the suppression member 20A can be positioned on the rear side of the front surface of the cage body 10.

[0043] Next, provide the first opening 11a1 in the vertical wire portion 11a of the front net 11 constituting the front surface of the cage body 10 (opening formation step: S13). The first opening 11a1 is provided at the position where the vertical wire portion 11a and the insertion member 110 intersect. Since the insertion member 110 is already provided, it can be provided with higher accuracy compared to the case of providing it in advance. The first opening 11a1 is formed by cutting the vertical line V and the horizontal line H.

[0044] Next, project the tip of the insertion member 110 to the outside from the first opening 11a1. When the cage body 10 is temporarily placed slightly forward, by moving it backward, the tip of the insertion member 110 will naturally project to the outside from the first opening 11a1. Note that instead of moving the cage body 10 back and forth, the insertion member 110 may be inserted deeper into or pulled out from the embedded object 120.

[0045] Then, overlap the net body 21 of the suppression member 20A on the vertical wire portion 11a from the rear side and fix the net body 21 to the vertical wire portion 11a (suppression member attachment step: S14).

[0046] Next, fill the cage body 10 with the stuffing material 30 (filling step: S15), and finally attach the lid net 14 to complete the construction of the futon cage 1.

[0047] Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made and implemented within the scope of the present invention. For example, the material of the annular body 22 is not limited to synthetic rubber, and may be synthetic resin or metal. If a steel plate is processed into a substantially donut shape or a substantially cylindrical shape to form the annular body 22, durability equivalent to that of the cage body 10 and the net body 21 can be obtained. Further, the annular body 22 may be omitted. In this case, the holes 21a of the net body 21 become the insertion holes 22a. The tips of the vertical lines V and horizontal lines H of the net body 21 on the hole 21a side are preferably covered with a covering material such as rubber. Further, the suppression member 20 may be attached to the second opening 12a1. Further, when the mesh of the vertical net portion 12a of the rear net 12 is larger than the inserted object 110, the mesh can be replaced with the second opening 12a1. That is, the second opening 12a1 is not necessarily provided.

[0048] The order of each process is an example, and it may be changed or omitted as appropriate. For example, after attaching the suppression member 20 to the inserted object 110, the inserted object 110 and the embedded object 120 may be connected. Further, when the embedded object 120 and the inserted object 110 are integral, the inserted object connection process is omitted, and the cage body 10 is installed on the slope 100 while passing the inserted object 110 through the first opening 11a1 and the second opening 12a1. The inserted object 110 is not limited to a drain pipe, and may be a long body such as a ground anchor.

[0049] Although the front net 11 and the rear net 12 have the bottom net portions 11b and 12b, the box body B may be formed by separately providing a bottom net without having them.

[0050] The cage body 10 does not necessarily need to be provided with the lid net 14. A suppression member 20A larger than the first opening 11a1 may be used during the construction shown in FIG. 4, or a suppression member 20 smaller than the first opening 11a1 may be used during the construction shown in FIG. 6. Further, the suppression members 20 and 20A may be stacked on the front surface of the cage body 10 from the outside.

[0051] If this application is changed to a design registration application, the suppression members 20 in FIGS. 3 and 7 may be extracted from the futon cage 1 as "articles related to the design". At this time, the suppression member 20 may be referred to as a "closing panel for the futon cage". Further, the annular body 22 of the suppression member 20 may be regarded as "the part to receive design registration", and the mesh body 21 of the suppression member 20 may be regarded as "the part other than the part to receive design registration as a partial design".
