Definitions

  • This invention relates to a reusable mesh mould for placing concrete, and relates to a construction method using this mould.
  • Mesh mould used to place concrete material are already known and the prior art mesh moulds have a structure in the form of a net, such as a wire net, stretched onto a frame, but it does not use a material that has strength as to support the horizontal loads of placed concrete material, so that horizontal loads cannot be supported.
  • a reusable mesh mould for placing concrete having an upright panel in which a mesh is stretched onto a frame, and the panel has both an outer frame forming a periphery thereof and also an inner frame joined to said outer frame, the panel having the strength to support a horizontal load of a concrete material placed within the mould, without being supported by supporting vertical pillars and auxiliary horizontal square bars.
  • the invention also includes a mesh mould construction method comprising the steps of:
  • One or more spacers may be used to connect the panels on opposite sides of the mould.
  • reinforcing bars are erected in the concrete material 4 that is in a mixed state.
  • the concrete material 4 that has a state of liquidity and does not have a state of solidity cannot maintain its own shape, as shown in Fig. 1(a), and therefore, it tends naturally to move from higher place to a lower place because of its weight (in other words, has a condition of stable potential energy).
  • the concrete material 4 enclosed in a mould by panels at both sides, including a mesh mould will attempt to move under gravity and, as a result, applies inevitably a horizontal load to the mould panels 1 as shown in Fig. 1(b), the horizontal load increasing as the position becomes lower.
  • the present invention is characterized in that the frame itself of the mesh mould has a strength that can support such a horizontal load.
  • the mesh mould panels are placed at both sides of the space into which the concrete material 4 is to be poured, the concrete material 4 can be supported until concrete is hardened, without being supported by substantially vertical supporting pillars and substantially horizontal auxiliary square bars, in spite of the fact that the mixed concrete material applies horizontal loads to the panels.
  • the mesh mould can also be integrated with the concrete structure if desired.
  • Fig. 2 shows a typical shape of a concrete mould panel 1 of the present invention.
  • the supporting frame 11 has not only an outer frame 11A but also an inner frame 11 B that is joined to the outer frame.
  • the thickness of the outer and inner frame parts 11, material, the width of the outer frame 11A, and the vertical and horizontal widths of the inner frame 11 B depend on the horizontal thickness and height of concrete to be placed.
  • the strength of the frame 11 is required in proportion to an increase in the height of the concrete structure and in proportion to a decrease in the horizontal thickness thereof.
  • the thickness of the outer and inner frame parts and the interval between the outer frame parts and the interval between the inner frame parts can be adapted proportionately as the height of the concrete structure to be placed becomes higher and the width thereof becomes narrower.
  • the frames 11 of the mesh mold panels1 erected at both sides are connected to each other by one or more separators 2 as shown in Fig.3, and thereby the erected state of the mould can be secured.
  • the separator 2 may have a bar shape that requires a given longitudinal length, and an ordinary connection method can be adopted in which the separator is connected to the frame 11 by, for example, a nut and bolt connection or a twisted wire connection.
  • FIG. 3 A side view is shown in Fig. 3, based on the mesh mould being flat. If a ferroconcrete structure or a concrete structure to be constructed is curved horizontally, a curved structure can be obtained by a previous arrangement in which the horizontal outer frame parts 11 of the mesh mould and the inner frame 11 thereof are curved.
  • Fig. 4 shows a mesh mold of the present invention and a typical example of a construction method that uses this.
  • Fig. 4(a) shows the shape of a typical mesh mould panel1 used in the present invention.
  • a number of vertical and horizontal inner frame parts 11 B are adopted in the mesh mould panel1 of the present invention as shown therein.
  • the height is substantially 1.2m, and the width in the lateral direction is about 1.5m to 1.8m. This derives from the fact that these widths best facilitate work for setting the mesh mould at both sides of the space into which the concrete is to be poured.
  • the diameter of the metal wires making up the mesh of the mesh mould is normally 0.4 to 0.6mm
  • the diameter of the frame parts 11 enclosing the mesh and in the vertical direction is normally 10 to15mm
  • the diameter of the frame parts 11 in the lateral direction is normally 5 to10mm.
  • the diameters of the metal wires and frame parts can be changed as required.
  • Fig. 4(b) shows the shape of a spacer 2 conveniently used in the present invention.
  • the spacer 2 has folds or hooks at both ends thereof in order to be hooked on to the frames 11.
  • a supporting frame 3 is disposed at the bottom in this embodiment, as shown in Fig. 4(c), and the mesh mould panels 1 are fitted into the supporting frame 3.
  • the shape of the supporting frame 3 is not limited to any specific one. Usually, fitted parts thereof are buried in the ground, and upper parts thereof on the ground are branch-shaped. The branch-shaped part thereof supports the frame 11 located at the lower end of the mesh mould panel 1. If the mesh mould is supported by the supporting frame 3, the mesh mould will be erected very stably.
  • a case is shown in which a single mesh mould panel 1 is used in the height direction.
  • an upper mesh mould panel 1 and a lower mesh mould panel 1 it is quite possible to connect an upper mesh mould panel 1 and a lower mesh mould panel 1 to each other by means of wire, and stack them successively so as to form a concrete structure having a necessary height.
  • the mesh mould construction method can be realized only by the separator connection without the complex work of, as in a situation of the prior art mesh mould, setting up and removing the substantially vertical supporting pillars and the substantially horizontal auxiliary square bars.
  • the frame of the mesh mould of the present invention has, by itself, a strength enough to support a horizontal load, and therefore, it can exert strong supporting integrally with the erected concrete even after the concrete structure is constructed.
