Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a gabion used for construction work such as seawalls, flood banks, and erosion control.

[Prior Art] There are two types of gabions: those that are cylindrical in the assembled state and square (rectangular) gabions, also known as "futon baskets," and both are filled with stones, etc. used. These are generally composed of a trunk-like mesh section, an upper surface mesh section that covers the open upper surface of the trunk-like mesh section, and a lower surface mesh section that closes the opened lower surface. In addition, this trunk-shaped net portion may be formed by connecting a plurality of side net portions separated by each side to each other to form a cylindrical or rectangular trunk shape, or furthermore, a plurality of partition net portions may be formed inside the trunk portion. Some rooms are divided into rooms.

One of the construction methods for assembling a predetermined gabion by connecting multiple net sections together is to transport the individual net sections that make up each section to the site without assembling them, and then attach the side net sections, partition net sections, etc. to the site. A method of assembling and integrating the trunk-like netting part and the bottom netting part sequentially, filling the inside with stones etc. during installation, and then installing the same net part by covering the top surface with the top netting part. There is.

[Problem that the invention aims to solve] This method allows each mesh section to be stacked, so many mesh sections can be transported at once, but it requires complicated assembly work on site, which reduces work efficiency. There was a problem that became extremely bad. Therefore, in this method, a structure is desired that allows the mesh parts to be connected and assembled with a simple operation.

The present invention has been made in view of the above problems, and its purpose is to provide a gabion with a structure that allows a large number of gabions to be transported at one time and improves workability during construction.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a gabion in which a side net is arranged upright on a bottom net and assembled into a predetermined shape, and the intermediate portion of the side net is assembled into a predetermined shape. The side mesh body is formed into an L-shape by being bent at the intermediate portion, and a first side mesh portion is provided on one side and a second side surface mesh portion is provided on the other side with the intermediate portion sandwiched therebetween. The lower end of the first side mesh portion and the lower end of the second side surface mesh portion are respectively placed in contact with each other on the bottom mesh portion.

[Function] According to the above configuration, when the lower end of the first side net and the lower end of the second side net are brought into contact with the bottom net, and the side net is disposed on the bottom net, ,
The first side net portion and the second side net portion, which are bent and intersect with each other, support each other and maintain the side net body in an upright state. Therefore,
When assembling the gabion, the side nets can be temporarily placed in a stable state by standing them in place on the bottom net without using any special supporting members, and then they can be easily fixed permanently using another connecting member. can do.

Further, one of the first side netting section and the second side netting section is used as a partitioning netting section for dividing the inside of the gabion main body into a plurality of rooms, and the other one is used as a part forming the outer surface of the gabion main body. Furthermore, both of these mesh sections can be attached at the same time. This can improve workability. In addition, before installation, the side mesh can be removed from the bottom mesh and the bottom mesh and side mesh can be stacked in contact with each other, so for example when storing in a warehouse. Also, many net sections can be arranged in a small space.
At the same time, it is possible to carry many nets at once when transporting them to the site. Thereby, storage costs and transportation costs can be reduced.

[Example] Hereinafter, an example of the present invention will be described in detail using the drawings.

FIG. 1 schematically shows an embodiment of a gabion to which the present invention is applied.

In the figure, a gabion 1 is composed of a box-shaped gabion body 2 with an open top while being installed on site, and an upper mesh body 3 that closes the top opening of the gabion body 2 after installation of the gabion body 2. ing.

Furthermore, the gabion main body 2 includes a bottom net portion 4 placed on the slope, and this bottom net portion 4
A first side mesh portion 5 forming a trunk-like mesh portion on top, a second side surface mesh portion 6 that divides the internal space defined by the first side mesh portion 5 into a plurality of small rooms, etc. It consists of The first side mesh portion 5 and the second side surface mesh portion 6 are integrally formed as a side surface mesh body 8.

The bottom mesh portion 4 is formed into a plate shape by a frame body 7 formed in the shape of a window frame using a relatively thick wire or the like, and a wire mesh 10 woven into the frame body 7 in a substantially diamond shape. It is placed in close contact with the slope.

On the other hand, the side netting body 8 consisting of the first side netting section 5 and the second side netting section 6 is formed into a window frame shape using a relatively thick wire such as wire, as shown separately in Fig. 5. It is composed of a frame 17 and a wire mesh 20 woven around the frame 17 in a substantially diamond shape.
Further, the middle part of the frame 17 is bent to form an L-shape, and a first side mesh part 5 is on one side of the middle part, and a second side face mesh part 6 is on the other side of the middle part. each formed. Note that a reinforcing member 18 made of the same wire rod as the frame 17 is attached to the intermediate portion by welding and fixing the upper and lower ends to the frame 17, respectively.
When this side net 8 is attached to the bottom net 4, first the lower end of the first side net 5 and the lower end of the second side net 6 are connected as shown in FIGS. 1 and 2. are temporarily placed in contact with predetermined positions on the bottom net portion 4, and the first side net portion 5
It is stably supported by the L-shaped bend formed by the and second side mesh portion 6. The side nets 8 are sequentially arranged with the middle portion of the next side net 8 adjacent to the free end portion of the first side net portion 5, and the second side net 8 is placed in the last portion. A plate-shaped side net portion formed only of the side net portion 6 is arranged. Next, the reinforcing material 18 provided between the bottom mesh portion 4 and the side mesh portion 8 and the intermediate portion of the side mesh portion 8 and the free end of the first side mesh portion 5 adjacent to the reinforcing material 18 A coil spring 9 is attached between the parts and the parts are connected and fixed to each other.
The connection and fixation using the coil spring 9 first brings the parts to be connected together into a state in which they are in contact with each other, as shown in FIG. Next, when the coil spring 9 is rotated and pushed in from one end side, a portion of the frame body 17 in both mesh portions is commonly disposed within the loop of the coil spring 9, thereby connecting them to each other.

Next, the top net 3 is formed independently from the gabion main body 2, and is made of relatively thick wire or the like, like the bottom net 4 and the side net 8 that form the gabion main body 2. A frame body 17 formed in the shape of a window frame with wire rods
A metal mesh 30 is woven into the frame 17 in a substantially diamond shape to form a plate shape.

Therefore, the gabion 1 configured in this way is
Until the transport is completed to the site, the top mesh 3, bottom mesh 4, and side mesh 8 can be disassembled and transported in a stacked state, so that the multiple mesh parts 3, 4 can be transported without being bulky. , 8 can be carried alone. Thereby, transportation costs can be reduced.

On the other hand, at the site, the bottom net section 4 is laid on the slope,
