DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope stabilizing structure for stabilizing a slope by constructing a mold on a slope by casting a hardening material.

[0002]

2. Description of the Related Art A slope stable structure is used in which a mold is assembled on a slope and a hardening material such as mortar or concrete is cast and the entire structure extends on the slope like a lattice.
The applicant of the present application has disclosed a method of constructing this
The invention described in Japanese Patent Application Laid-Open No. 3-533 is disclosed. This means that the vertical formwork extending in the direction of the slope is continuously assembled, a horizontal formwork is spanned between the adjacent vertical formwork, and reinforcement is provided so as to surround the intersection of the vertical formwork and the horizontal formwork. A mold plate is hung diagonally between the molds, and a hardening material is also cast inside the four reinforcing mold plates to reinforce the intersection. Continuing the vertical formwork as in the present invention has the advantage that the setting material can be easily poured into the vertical formwork.

[0003]

However, if the horizontal form is laid on a single form plate and spanned between adjacent vertical forms, each time the distance between adjacent vertical forms is different, Accordingly, it is necessary to cut or add the form plate, which is extremely troublesome. Therefore, the work on site increases and the construction period becomes longer.

[0004] Further, if the reinforcing form plates are bridged one by one between the vertical form and the horizontal form, a part of the form plates located inside the reinforcing form plates is overlapped and wasted. At the same time, it is difficult to place a hardening material into a small space surrounded by the reinforcing form plate and the horizontal form.

[0005] Further, since the four reinforcing form plates are connected to the vertical form plate and the horizontal form plate at both ends, respectively, there are eight connecting portions surrounding the intersection. When there are a large number of connecting portions, any one of the connecting portions is disconnected due to the weight of the hardening material or the like, and there is a problem that repair work is increased. Furthermore, if both ends are connected to the vertical or horizontal frame, if the connection is not performed accurately enough, the upper, lower, left, and right connecting portions will shift, and the shape of the reinforcing portion will be unbalanced. .

Further, the reinforcing bars arranged inside the vertical and horizontal formwork are shifted up and down and intersect, so that the heights of the reinforcing bars with respect to the formwork plate are variously different. The reinforcing bars are supported by spacers that connect between the form plates as members for supporting the reinforcing bars.However, if the spacers can only be attached to the form plates at the same height, I can't support it.

[0007] The present invention has been made to solve the above-mentioned problems, and is easy to construct and does not waste material.
It is an object of the present invention to provide a slope stabilization structure that can be constructed as designed.

[0008]

SUMMARY OF THE INVENTION A slope stabilizing structure according to the present invention is formed by erecting a form plate made of expanded metal or crimped wire mesh in parallel to form a vertical form. Install continuously in the tilt direction. The vertical formwork is not limited to one long formwork plate, but may be a combination of a plurality of formwork plates. A plurality of such vertical forms are assembled at appropriate intervals. A horizontal form frame is placed between the adjacent left and right vertical frames with two form plates facing each other. The horizontal form is composed of a plurality of crimped wire meshes, and these are joined to form one form plate. Splicing refers to joining ends by overlapping each other. A plurality of rings are respectively mounted on the left and right form plates of the horizontal form. Attach spacer connecting bars according to the height of the reinforcing bars arranged inside, and connect the left and right form plates.

The ends of the two form plates of the horizontal form are bent approximately 45 degrees in the direction away from each other. A protruding portion is protruded from the tip of the form plate of the horizontal formwork. In the case of a crimped wire mesh, the tip of the lateral steel wire constituting the crimped wire mesh is made to protrude slightly longer as a protruding portion. In the case of expanded metal, a claw-shaped member can be protruded as a protruding portion. Alternatively, a protruding portion may be formed by protruding in a V-shape, leaving one square forming a net of the expanded metal. This steel wire is inserted into the mesh of the form plate of the vertical formwork, and the horizontal formwork is connected to the vertical formwork.

[0010] In the vertical form and the horizontal form as described above, reinforcing bars are arranged in the form plate along the length direction. The reinforcing bars arranged in the horizontal form penetrate the vertical form. Will do. A hardening material such as mortar, concrete, or resin mortar is poured into these molds to construct a structure in which vertical beams and horizontal beams extend in a grid on the slope. The hardening material cast between the form plates opened to the left and right of the horizontal form forms a reinforcing portion for reinforcing the intersection where the vertical beam and the horizontal beam intersect. The horizontal formwork described above may also be formed by combining a plurality of divided wire meshes.

[0011]

In order to join a plurality of expanded metal or crimped wire nets, the length of the overlapped portion is adjusted according to the interval between adjacent vertical forms, and the form plates of the horizontal form are joined together. It can be arranged exactly in between. The work is easy because the protruding portion protruding from the tip is hung by using expanded metal or crimped wire netting divided into a plurality of pieces. There is no waste of material because the form plate of the horizontal form also serves as the form plate of the reinforcing part. Since the bent horizontal frame is not doubled, it is easy to drive the hardening material into the reinforcing portion. It is only necessary to connect only the leading end of the horizontal formwork plate to the vertical formwork with few connecting points and little possibility of detachment, and the shape of the reinforcing portion can be easily formed. The spacer connecting bar can be hung on a ring of an appropriate height to support the reinforcing bar at an appropriate height.
