本発明に係る請求項1の円筒金網枠体では、円筒金網枠本体に中詰材を投入すると、各円弧金網枠片は、中詰材の投入に伴う圧力(土圧)によって、相互の間隔(各円弧金網枠片間の間隔/隙間)を広げつつ離間(移動)する。各円弧金網枠片は、中詰材の投入に伴って、一方の円弧金網枠片の周端縦金属線及び補強縦金属線を各補強金具に当接(接触)することなく、各周端縦金属線及び各補強縦金属線で各コイル金属線を各円弧金網枠片が離間する方向に弾性変形して広げつつ相互に離間(移動)する。各補強金具は、中詰材の投入によって、一方の円弧金網枠片の周端縦金属線及び補強縦金属線と当接することなく、充填隙間の範囲において各円弧金網枠片の離間(移動)を許容し、中詰材を充填した円筒金網枠本体において、一方の円弧金網枠片の周端縦金属線及び補強縦金属線と当接する。
これにより、円筒金網枠体は、中詰材の投入から充填までの間に、各補強金具を円周方向各端の一方の円弧金網枠片の周端縦金属線及び補強縦金属線に当接することなく、中詰材の充填に伴って、各補強金具が周端縦金属線及び補強縦金属線に当接するので、周端縦金属線及び補強縦金属線を変形(曲げる等の変形)させない。円筒金網枠体は、中詰材の投入に伴って、弾性変形した各コイル金属線(バネ力)によって各円弧金網枠片の各周端縦金属線及び各補強縦金属線を締付け、各円弧金網枠片の連結を維持する。
円筒金網枠本体内に中詰材を充填すると、各補強金具は、一方の円弧金網枠片の周端縦金属線及び補強縦金属線に当接する。各補強金具は、他方の円弧金網枠片の周端縦金属線及び補強縦金属線に取付けられる。

In the cylindrical wire mesh frame body of claim 1 according to the present invention, when the filling material is charged into the cylindrical wire mesh frame main body, the arcuate wire mesh frame pieces are spaced apart from each other due to the pressure (earth pressure) accompanying the charging of the filling material. Separate (move) while widening (interval / gap between each arc wire mesh frame piece). Each arcuate wire mesh frame piece has its peripheral end without abutting (contacting) the peripheral vertical metal wire and the reinforcing vertical metal wire of one of the arcuate wire mesh frame pieces with the filling material. Each coil metal wire is elastically deformed in the direction in which each arcuate wire mesh frame piece is separated by the vertical metal wire and each reinforced vertical metal wire, and is separated (moved) from each other while being widened. Each reinforcing metal fitting is separated (moved) from each arc wire mesh frame piece within the range of the filling gap without contacting the peripheral vertical metal wire and the reinforcing vertical metal wire of one arc wire mesh frame piece by inserting the filling material. In the cylindrical wire mesh frame main body filled with the filling material, it comes into contact with the peripheral vertical metal wire and the reinforcing vertical metal wire of one of the arcuate wire mesh frame pieces.
As a result, the cylindrical wire mesh frame body hits each reinforcing metal fitting with the peripheral end vertical metal wire and the reinforcing vertical metal wire of one arc wire mesh frame piece at each end in the circumferential direction during the period from the charging of the filling material to the filling. Since each reinforcing metal fitting comes into contact with the peripheral vertical metal wire and the reinforcing vertical metal wire as the filling material is filled without contact, the peripheral vertical metal wire and the reinforcing vertical metal wire are deformed (deformation such as bending). I won't let you. In the cylindrical wire mesh frame body, each arcuate vertical metal wire and each reinforcing vertical metal wire of each arcuate wire mesh frame piece are tightened by each elastically deformed coil metal wire (spring force) with the addition of the filling material. Maintain the connection of the wire mesh frame pieces.
When the filling material is filled in the cylindrical wire mesh frame body, each reinforcing metal fitting comes into contact with the peripheral end vertical metal wire and the reinforcing vertical metal wire of one arc wire mesh frame piece. Each reinforcing metal fitting is attached to the peripheral end vertical metal wire and the reinforcing vertical metal wire of the other arcuate wire mesh frame piece.
As a result, each reinforcing metal fitting is a cylindrical wire mesh frame main body filled with a filling material, and even if a load [for example, a load (weight) of a structure] is applied from one of the cylinder end openings, each peripheral end vertical metal wire And by being attached to and abutting against each reinforced vertical metal wire, it is possible to prevent the arcuate wire mesh frame pieces from being separated from each other. Each arc wire mesh frame piece has each peripheral end vertical metal wire and each reinforcing vertical metal while widening the mutual interval (gap) by the load acting on the cylindrical wire mesh frame main body filled with the filling material from one of the cylinder end openings. Each coil metal wire is elastically deformed by a wire to try to separate (move) in the direction of separation, but each reinforcing metal fitting has each circumference in cooperation with each peripheral end vertical metal wire and each reinforcing vertical metal wire. It is possible to prevent the arc wire mesh frame pieces from being separated from each other on the opening side of one of the cylinder ends at each end in the direction.
In this way, the cylindrical wire mesh frame body suppresses the separation (movement) of each arcuate wire mesh frame piece by the cooperation of each reinforcing metal fitting, each peripheral end vertical metal wire, and each reinforcing vertical metal wire. Even if a load (weight) such as a structure is applied to the main body of the cylindrical hole wire mesh frame filled with the filling material from the opening, each coil metal wire that elastically deforms on one cylinder end opening side at each end in the circumferential direction is It is possible to prevent the cylindrical wire mesh frame body from collapsing (breaking / disassembling) due to the detachment from the arcuate wire mesh frame body and the separation of the arc wire mesh frame pieces.
In claim 1, the cylindrical wire mesh frame body is composed of a metal cylindrical wire mesh frame main body (each arc wire mesh frame piece, each reinforcing vertical metal wire and each coil metal wire), and a metal reinforcing metal fitting. The load bearing stress (kN / m 2 ) can be increased (increased), and the applicable range for the load of the structure can be expanded.

As a result, each reinforcing metal fitting is a cylindrical wire mesh frame main body filled with a filling material, and even if a load [for example, a load (weight) of a structure] is applied from one of the cylinder end openings, each peripheral end vertical metal wire By being taken in and in contact with each other, the arcuate wire mesh frame pieces are prevented from being separated from each other. Each arc wire mesh frame piece has each coil metal wire at each peripheral end vertical metal wire while widening the mutual interval (gap) by the load acting on the cylindrical wire mesh frame main body filled with the filling material from one cylinder end opening. However, in cooperation with each peripheral vertical metal wire, each arc wire mesh frame piece is mutually deformed on one cylinder end opening side of each end in each circumferential direction. Suppress separation.
In this way, the cylindrical wire mesh frame body suppresses the separation (movement) of each arc wire mesh frame piece by the cooperation of each reinforcing metal fitting and each peripheral end vertical metal wire, so that the filling material is filled from one cylinder end opening. Even if a load (weight) of a structure or the like is applied to the cylindrical wire mesh frame body filled with This makes it possible to prevent the cylindrical wire mesh frame body from collapsing (breaking / disassembling) due to the separation of the arcuate wire mesh frame pieces.
In claim 2, since the cylindrical wire mesh frame body is composed of a metal cylindrical wire mesh frame main body (each arc wire mesh frame piece and each coil metal wire) and a metal reinforcing metal fitting, the load bearing stress (kN /). m 2 ) can be increased (increased), and the range of application to the load of the structure can be expanded.

In the "graph diagram" of FIG. 49, the horizontal axis (X-axis) is "displacement amount (mm) of the cylindrical wire mesh frame main body Y1 (upper loading plate)", and the vertical axis (Y-axis) is "loading pressure (kN / m)". 2 ) ”.

図49の「グラフ図」において、実施例1は、供試体1の耐荷圧力qmax=1230(kN/m)、供試体2の耐荷圧力qmax=1294(kN/m)、及び供試体3の耐荷圧力qmax=765(kN/m)を得た。全ての供試体1〜3の平均耐荷圧力qav=1096(kN/m)となる。 In the "graph diagram" of FIG. 49, in Example 1, the load-bearing pressure qmax = 1230 (kN / m 2 ) of the test piece 1, the load-bearing pressure qmax = 1294 (kN / m 2 ) of the test piece 2, and the test piece 3 The load-bearing pressure qmax = 765 (kN / m 2 ) was obtained.
