【Example】

Embodiments of the present invention will be described below with reference to the drawings. FIG. 5 is a diagram showing the bottom net body unit members in two rows shown in FIG. 4 in an unfolded state. The present invention is applied to bottom net body unit members A ₂₁ , A ₂₂ or bottom net body unit members A ₃₁ , A ₃₂ and bottom net body unit members A ₄₁ , A _{42 which} are connected in the column direction).

In this case, the two bottom net body unit members A ₂₁ , A ₂₂ or A ₃₁ , A ₃₂ or A ₄₁ , A ₄₂ are respectively used in the factory for the bottom net body, the partition net body, the end net body, and the side net. After the net is assembled and connected at the connecting portion, it is sent as a set from the factory to the construction site. In the present invention, the bottom net unit members A ₂₁ and A ₂₂ or A ₃₁ , Although the connection part with A ₃₂ or A ₄₁ , A ₄₂ is connected with the same structure as the conventional one (connection of the frame body of the bottom net body by the coil spring), when the bottom net body is folded, The present invention relates to a means for reducing the influence of partition nets located between bottom nets and helping to make them compact during transportation.

As an embodiment of the present invention, a bottom net body unit member A is shown in FIG. The bottom net body unit member A includes a bottom net body 3 in which an iron wire rhomboid net 2 is stretched over a frame body 1 having a width of 1 to 2 m and a length of 2 to 4 m. , Side nets 4 as vertical partitions corresponding to the size of the bottom net unit member A, end nets 5 as lateral partitions corresponding to the size of the bottom net unit member A, slopes A partition net 6 for laterally partitioning the size of the bottom net body unit member A located at a portion is provided.

Like the bottom net body 3, each of the side net body 4, the end net body 5, and the partition net body 6 has a structure in which an iron wire diamond net is stretched around the frame body. The frame body having a size of 0.2 to 1 m and a length of 2 to 4 m, the end net body 5, and the partition net 6 are a frame body having a height of 0.2 to 1 m and a length of 1 to 2 m. .

In FIG. 1, the side net body 4 ₁ , the end net body 5 ₁ , the first bottom net body 3 _{1 to} which the partition net body 6 ₁ is attached, the side net body 4 ₂ , the end net body 5 ₂ , the partition net assembly 6 ₂ second bottom net body 3 ₂ which consists part of the attached is a first bottom net body 3 ₁ frame 1 ₁ and the second bottom net body 3 ₂ frame 1 ₂ and the The state where the facing portions are connected and assembled by a coil spring 7 as a connecting means B of a known means is shown.

According to the present invention, when the two first bottom net bodies 3 ₁ and the second bottom net bodies 3 ₂ are assembled and produced by a factory and then transported to the construction site from the factory, the coil spring 7 is used. when folded into the first bottom net body 3 ₁ of frame 1 ₁ and clamshell around the connection portion of the second bottom net body 3 ₂ of the frame 1 ₂ connect, the first bottom grid member Each of the partition net body 6 ₁ and the partition net body 6 ₂ sandwiched between 3 ₁ and the second bottom net body 3 ₂ moves so as to be separated from the position of the connection portion B to facilitate folding. be able to.

With respect to the connecting portion B connected by the coil spring 7, the first bottom net body 3₁And the second bottom net 3₂Includes a reinforcing frame 8 supported in a direction orthogonal to the frame body of the connecting portion B. ₁ , 8₂Each has a partition net 6₁, 6₂Is installed. In the present invention, this reinforcing frame 8₁, 8₂At the position of, the first bottom net 3₁, Second bottom net 3₂Each wire mesh 2₁, 2₂Are locked with a predetermined pitch P, and the partition net body 6₁, 6₂The wire nets are also locked with the same pitch P.

Each reinforcing frame 8₁, 8₂Partition net body 6 attached to₁, 6₂A magnified view of the section is shown in FIG. In FIG. 2, the first bottom net body 3 on the left side₁Partition net body 6 ₁ Is located at a location where construction is performed on site, and the second bottom net body 3 on the right side is₂Partition net 6₂Shows the state of being arranged at a position moved away from the connecting portion B.

As is clear from FIG. 2, at the position of the connecting portion B, the side net body 4 ₂ attached to the second bottom net body 3 ₂ on the right side is located, and the side net body 4 ₂ is orthogonal to the connecting portion B. one bottom net body 3 ₁ and the reinforcing frame _81, 82 which are respectively disposed in the second center position of the bottom net body 3 _2, the partition net body 6 _and 62 of the frame, a predetermined pitch The wire nets at intervals of P are located so as to face each other, and the reinforcing frames 8 ₁ and 8 ₂ and the frame bodies of the partition nets 6 ₁ and 6 _{2 which} face each other are halved of the interval of the predetermined pitch P. They are coupled by a coupling coil 9 shorter than one length. In this case, the coupling coil 9 is located when the reinforcing frames 8 ₁ and 8 ₂ and the frame bodies of the partition nets 6 ₁ and 6 ₂ are installed at the site (first bottom net in FIG. 2). body 3 ₁ partition network element 6 ₁ position in), the range of a predetermined pitch P, is attached to the reinforcing frame _81, 82 side in a position farthest from the connecting portion B.

Therefore, the coupling coil 9 having a length equal to or smaller than half the pitch interval P surrounds the reinforcing frame 8 ₁ and the frame body of the partition net body 6 ₁ between the pitches of the wire meshes, and Since both ends of the connecting coil 9 are locked to the reinforcing frame 8 ₁ side, the frame body of the partition net body 6 ₁ is connected to the reinforcing frame 8 _{1 of} the first bottom net body 3 ₁ at the connecting portion B ₁ . It is possible to move the wire in a direction away from the position of at least half of the pitch interval P of the wire mesh. The moved state can be understood from the second bottom net body 3 ₂ disposed on the right side of Figure 2.

Therefore, in the factory, the connecting portions B of the opposing frame bodies of the two bottom net bodies are connected by the coil springs 7, and the side net bodies are attached to the frame body 1 and the reinforcing frame 8 of each bottom net body 3. The end net body and the partition net body are attached respectively. Among them, the partition net body and the like which are attached in the direction orthogonal to the connecting portion B are approximately half the attachment pitch P of the wire net 2 to the reinforcing frame 8. When the bottom nets 3 ₁ , 3 ₂ are folded in two via the connecting part B when transported from the factory to the construction site by being locked by the coupling coil 9 having the length shown in FIG. As described above, the partition nets 6 ₁ and 6 ₂ and the end nets 5 ₁ and 5 ₂ fall between the two bottom nets 3 ₁ and 3 ₂ and at the same time, the distance from the connecting portion B is P / 2. Move away. In this drawing, the side net body 4 ₂ is located at the position of the connecting portion B in a tilted state, and the side net body 4 ₁ attached to the bottom net body 3 ₁ is located at the end position distant from the connecting portion B. They are arranged in parallel with the net body 3 ₁ .

Therefore, by moving the net located between the bottom nets 3 ₁ , 3 ₂ from the position of the connection portion B, it is possible to compactly fold the two bottom nets. At the site, the stone net is formed in a short time by opening the folded bottom net, raising the partition net, etc., and fixing the partition net returned to the predetermined position.
