The present invention has the following effects. (1) In the first aspect of the invention, the wire includes a first inclined portion, a first substantially V portion, a second inclined portion, a connecting portion to the next substantially Λ portion, the substantially Λ portion, and the next third inclined portion. Forming a connection portion, a third inclined portion, a second substantially V portion, and a fourth inclined portion. In the second aspect of the invention, the first inclined portion, the first substantially V portion, the second inclined portion, the connection portion to the first substantially Λ portion, the first substantially Λ portion, and the second substantially Λ portion are provided on the wire. Forming a second connection portion, a second substantially Λ portion, a connection portion to the third inclined portion, a third inclined portion, a second substantially V portion, and a fourth inclined portion. On the other hand, in the conventional measurement frame described in Patent Document 1 (hereinafter referred to as the prior art), in the measurement frame having a function of fixing (floating and holding) one core material, there are six steel wires. In addition, the number of wire connecting (connecting) points such as welding of these steel wire rods reaches eight, resulting in high costs. On the other hand, in the present invention, it does not require as many as six steel wires as in the above-mentioned prior art to have a function of fixing at least one upper and one lower core material, for example, one wire Since the inspection frame can be manufactured from the above, cost reduction can be achieved. Moreover, the amount of wire necessary for obtaining a measurement frame capable of reliably forming a bulging body having a predetermined shape and a predetermined strength is, for example, 245 cm in the above-mentioned prior art, and the measurement obtained by the present invention. The frame is 195 cm, which is about 20% less, and the cost can be reduced in terms of the material used.

(2) For example, as shown in FIGS. 11 to 18, the first and second inclined portions that serve as a measure of the bulging body shape are provided in one measurement frame via the two connection portions 10 ′ and 10 ″. (5, 7) and the third and fourth inclined portions (13, 15) are arranged to face each other at an appropriate interval in the length direction of the measurement frame (the direction indicated by the double arrow D). For example, as shown in FIGS. 1, 3, 6, 7, and 9, the first and second bulges can be used as a guide for the shape of the bulging body due to the presence of the connecting portion that connects the second substantially Λ portion and the third substantially Λ portion. The inclined portion and the third and fourth inclined portions are disposed to face each other with an appropriate interval in the length direction of the measurement frame (the direction indicated by the double arrow D). For example, in the ones shown in FIGS. 1, 3, 6, 7, and 9, the first substantially V portion and the second substantially V portion are provided on the opposed inclined portions, respectively, on the opposite inclined portions side. , A first substantially Λ portion, a second substantially Λ portion, a third substantially Λ portion, and a fourth substantially Λ portion, respectively. Therefore, for example, when forming a grid-like bulging body, only one inspection frame of the present invention is installed on one side of the grid-like core material, and one upper core material is connected to the first substantially V portion and the second portion. Since it can be fixed (positioned) at approximately two portions of the V portion, the two lower core members are also fixed (positioned) at any one of the first approximately Λ portion to the fourth approximately Λ portion. So, for example, installation of one inspection frame, for example, the upper one and lower two core materials are fixed (positioned) in one place, respectively, compared to the measurement frame, the work of placing the curing material For example, since the upper one core and the lower two cores can be fixed (positioned) at two locations, respectively, it is possible to reliably form a bulging body having a predetermined shape and a predetermined strength. it can.

(3) Even if one side of the grid-like core material becomes longer, the first substantially Λ portion and the second substantially Λ are formed according to the length, for example, as shown in FIGS. Since the connecting portion for connecting the portions can be set to an appropriate length along the side direction, it is not necessary to provide a plurality of measurement frames on one side of the grid-like core material, which is economical. Moreover, in what is shown in FIGS. 11-18, since two said connection part 10 ', 10' 'can be set to an appropriate length, it provides multiple test frames in one side of a lattice-like core material. It is not necessary and is economical.

(4) Also, in the present invention, due to the presence of the two connecting portions 10 ′ and 10 ″ including one substantially Λ portion 9 ′ for floatingly holding one lower core member, or Due to the presence of the connecting portion connecting the first substantially Λ portion and the second substantially Λ portion, a work space for binding and fixing the core material is opened, and a wide work space can be secured. In this case, the two connecting portions 10 ′ and 10 ″ including the one approximately Λ portion 9 ′ are formed at a low position in contact with a covering material such as a wire mesh, or the first approximately Λ By forming the connection portion connecting the portion and the second substantially Λ portion at a low position so as to be in contact with a covering material such as a wire mesh, a wider working space in the measurement frame can be secured.

(5) In addition, the measurement frame for double reinforcement that fixes the upper and lower two-stage core material obtained by the manufacturing method having the above-mentioned characteristic configuration is not bulky, so it does not take up storage space, and can be carried and transported. It is also easy and has the advantage of excellent workability on site. (6) In addition, any of the measurement frames according to the present invention can be easily adapted to the unevenness of the slope by simply bending one wire rod that is an intermediate part of the measurement frame according to the unevenness of the slope. It is possible to reduce the waste of the curing material to be provided later.

The direction of shifting is along the D direction. The continuous portions 7a and 7a 'are located on the same horizontal plane as the horizontal sides 30 and 30', respectively.

The connecting portion 8 includes a horizontal side portion 30 and a continuous portion 7a, and the connecting portion 12 includes a horizontal side portion 30 'and a continuous portion 7a'. Further, the first substantially Λ portion 9 is bent toward the leg 20 in a direction perpendicular to the D direction from the downstream end n of the continuous portion 7 a and is connected to the horizontal side portion 30 in an obliquely upward direction. Through the apex T that is higher than the same horizontal position where the installation portion 7a is formed by a predetermined length e, it is further provided so as to bend toward the leg 20 and obliquely downward. On the other hand, the second substantially Λ portion 11 is bent to the side of the leg 22 in a direction perpendicular to the D direction from the end n ′ of the continuous portion 7a ′, and is connected to the horizontal side portion 30 obliquely upward.

Further, the connecting portion 10 is formed in a single horizontal straight line, which is the bottom end 9a on the downstream end side of the first substantially Λ portion 9 and the upstream end side of the second substantially Λ portion 11. The hem end 11a is connected (connected).

In this embodiment, the connecting portion 10 is positioned on the same horizontal plane as the horizontal side portions 30 and 30 ′, the horizontal side portions 25 and 25 ′, and the connecting portions 7 a and 7 a ′, and is in contact with the upper surface i of the wire net K. It is formed at such a low position (abuts).

Thus, in the wire bending apparatus, one wire R is bent in the order of the first step, the second step, the tenth step and the eleventh step, and the inspection frame 1 having a desired shape is obtained. Can be obtained. Then, a covering material such as a rhombus metal mesh K having a mesh of about 5 to 6 cm, for example, is laid on the pre-shaped slope 2 and an anchor (not shown) is driven into the slope 2 at an appropriate interval to form the wire mesh K. Fix to slope 2. Next, the reinforcing bars 3 and 4 having a diameter of, for example, about 6 to 10 mm are combined and arranged on the wire mesh K in a substantially square lattice shape having a side L of about 1 to 2 m. Then, the inspection frame 1 obtained by the wire bending device is arranged at the approximate center of each grid-like side composed of the reinforcing bars 3 and 4 so that the arc-shaped portions A and A straddle the reinforcing bars 3 and 4 and the wire mesh. Place on K. In this embodiment, the concave portion 24 of the leg 20, the concave portion 24 ′ of the leg 21, the leg 21 and the leg 23 are placed on the slope 2, and the connecting portion 10, the horizontal side portions 30 and 30 ′, and the horizontal side The measurement frame 1 is arranged with the portions 25, 25 ′ and the continuous portions 7a, 7a ′ being in contact with the upper surface i of the wire mesh K. However, the arrangement of the measurement frame 1 can be appropriately changed according to circumstances. Since this inspection frame 1 serves as a guide for the spray width and spray width height of the mortar 17 or the like, it is sufficient that at least one is provided on each side of the lattice frame. When the length L (see FIG. 1) is 1 to 2 m and the length Q of the measurement frame 1 is 40 to 50 cm, it is only necessary to provide one measurement frame 1 on each side. Further, when the side length L is larger, the length Q of the inspection frame 1 may be made larger. That is, the inspection frame 1 in which the length of the connecting portion 10 is made larger may be used. And in this embodiment, since the said connection part 10 is formed in the low position which touches the upper surface i of the metal-mesh K, and the work space which performs a bundling and fixing work is open | released, in the measurement frame 1 The operator can easily put his hands into the first substantially V portion 6, the second substantially V portion 14, the first substantially Λ portion 9 and the second substantially Λ portion 11 of each of the reinforcing bars 3 and 4, and the inserted reinforcing bars 3. And 4 of the first substantially V portion 6, the second substantially V portion 14, the first substantially Λ portion 9, and the second substantially Λ portion 11 can be easily inserted, bound, and fixed. For example, a low slump mortar having a moisture content of about 7 to 8% is sprayed on the grid-like reinforcing bars 3 and 4 configured as described above by a civil engineering sprayer such as a mortar gun machine. In this case, a measurement frame 1 serving as a guide for the spray width and spray height of 17 such as mortar is provided on each side of the lattice frame formed by the reinforcing bars 3 and 4. By simply spraying 17 such as mortar, a lattice method frame M made of 17 having a predetermined size can be easily formed. In other words, in this embodiment, the lattice-like method frame M having a lower end width of 35 cm and a height of about 15 cm can be formed, and the lattice-like method frame M having a predetermined size and a predetermined strength can be reliably formed. Subsequently, the vegetation material is sprayed into the frame of the grid-like method frame M by using a power sprayer or the like to form a vegetation layer J (thickness of about 3 to 5 cm from the slope 2). It is also possible to introduce vegetation into the slope, which greatly contributes to the improvement of the landscape of slope 2 and the permanent stability of slope 2 due to the roots and stems of the vegetation. In this case, before spraying the mortar and the like 17 forming the grid-like frame M, a sheet for protecting the mortar and the like 17 from adhering to the ground (slope) 2 in the frame is installed, After forming the shape method frame M, before the vegetation material is sprayed, the sheet is removed, so that the vegetation introduced by spraying can be well attached to the natural ground (slope) 2. In addition, when greening in the frame of the grid-like frame M is not required, the ground between the frame frames (slope) by spraying 17 with mortar or the like in the frame or covering with a padding material such as crushed stone. Two protections are possible.
