Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a slope protection construction formwork used when constructing a protective lattice frame on a slope surface.

[Conventional technology]

Slopes constructed with protective lattice frames have recently been attracting attention because they can be used in conjunction with grass and other vegetation work on the latticework within the lattice frames. For example, as shown in FIG. 5, the frame is constructed by attaching hooks 23, 23 at both ends of upper and lower connecting rods 22, 22, which are arranged in parallel at an appropriate interval in the longitudinal direction between the wire meshes 21, 21 installed oppositely on both sides. The wire meshes 21, 21 are engaged with each other.

[Problem that the invention attempts to solve]

However, when the above formwork is placed on a slope during slope protection construction and fresh concrete is poured between the wire meshes 21, 21, the wire meshes 21, 21 bulge outward due to the pressure of the fresh concrete at that time. This tends to cause deformation and has a negative effect on the strength of the slope protection lattice frame after concrete is poured.If wire mesh 21, 21 with a thick wire diameter is used to prevent this, the cost will be high. It was hot.

Therefore, the present invention aims to provide a formwork for slope protection construction that can prevent deformation due to the bulge of the wire mesh during pouring of fresh concrete and increase the strength of the slope protection lattice frame after concrete pouring. It is something to do.

[Means for solving problems]

In other words, the formwork for slope protection construction of the present invention has vertically long wire meshes installed on both the left and right sides, and inner hinges formed at required intervals on the horizontal reinforcing rods arranged above and below the outside of the wire meshes. The side protrusions are inserted through the mesh of the wire mesh on the corresponding side, and the L-shaped bent ends for the hinges of the connecting rods arranged vertically at a required interval in the vertical direction between the wire meshes are inserted into the mesh of the wire mesh on the corresponding side. The reinforcing rod is engaged with the inward protrusion of the reinforcing rod, and the center portions of the upper and lower connecting rods are connected by a vertical rod.

[Effect]

Such formwork is placed along the protective construction lattice frame to be formed on the slope during slope protection construction, and ready-mixed concrete is poured between the wire meshes. Then, the wire mesh tends to bulge outward due to the pressure of the fresh concrete during pouring, but the reinforcing rods connected by the connecting rods are located on the outside of the wire mesh and strongly prevent the wire mesh from expanding. Even after pouring fresh concrete, these reinforcing rods,
The connecting rods serve as reinforcing bones for the protective lattice frame.

In addition, when transporting and storing this formwork, the hinge between the inward protrusion of the reinforcing rod and the bent end of the connecting rod is used to move the wire mesh on both sides in parallel to form an overlapping state, thereby reducing the overall volume. .

〔Example〕

Next, an embodiment shown in FIGS. 1 to 4 will be described. The formwork of this example has vertically long wire meshes 1, 1 placed opposite each other on both the left and right sides, and is arranged in parallel above and below the outside of the wire meshes 1, 1. U-shaped inward protrusions 3, 3 for hinges are bent at required intervals on the reinforcing rods 2, 2 in the horizontal direction, and the inward protrusions 3, 3 are connected to the meshes of the corresponding wire meshes 1, 1. L-shaped bent ends 5 for hinges are inserted into the connecting rods 4 to 4, which are arranged vertically at required intervals between the wire meshes 1 and 1 and arranged vertically.
5, the bent ends 5, 5 are engaged with the inward protrusions 3, 3 of the corresponding reinforcing rods, and the upper and lower connecting rods 4, 4 are connected to each other.
A vertical rod 6 is passed across and welded to the center of the frame.

In the case of the formwork of this example, it is arranged along the protective construction lattice frame 8 to be formed on the slope surface 7,
As shown in FIG. 3, vertical rods 6 and connecting rods 4 are attached to reinforcements 9, 9 arranged above and below the central part of the protective construction lattice frame 8.

shall be.

During this pouring, the wire meshes 1, 1 tend to bulge outward due to the pressure of the fresh concrete, but the connecting rods 4
The reinforcing rods 2, 2 connected by ~4 are connected to the wire mesh 1,
1, and strongly prevents the wire meshes 1, 1 from expanding. Even after pouring the fresh concrete 10, these reinforcing rods 2, 2 and connecting rods 4 to 4 serve as reinforcing bones for the protective lattice frame 8.

In addition, when transporting and storing this formwork, the wire meshes 1, 1 are moved in parallel using the hinge between the inward protrusion 3 of the reinforcing rod and the bent end 5 of the connecting rod, so that the wire meshes 1, 1 are moved in parallel to the imaginary line in FIG. As shown by 11, they are placed in an overlapping state to reduce the overall volume.

[Effect of idea]

In this way, in the present invention, when pouring fresh concrete, the reinforcing rods connected to the connecting rods are placed on the outside of the wire mesh, which strongly prevents the wire mesh from expanding outward and prevents it from losing its shape. , these connecting rods and reinforcing rods can play the role of reinforcing bones even after concrete is poured, increasing the strength of the lattice frame for slope protection construction.Furthermore, during transportation and storage, the hinges of the connecting rods and reinforcing rods can be used to keep the wire mesh parallel. They can be moved and stacked to reduce the overall volume.
