Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a formwork used for constructing a structure for the purpose of protecting a slope, and more particularly to a formwork that can be easily assembled.

[0002]

[Prior Art]

 The applicant of the present invention discloses the invention according to Japanese Patent Application No. 61-142332 (Japanese Patent Publication No. 33856 / SHO). According to the invention, the formwork is installed on the slope in a grid pattern, and the formwork is installed so as to surround the grid-like intersection. A hardening material is cast into the formwork to form a grid-like method frame part and a cross-reinforcement part that reinforces the intersections.The cross-reinforcement part protects the intersections where stress concentrates and strengthens the strength. It will be a large slope protection structure. In order to connect and fix the formwork of the method frame part and the formwork of the cross reinforcement part by such a construction method, the weir plates of both formwork were tied with a binding wire.

[0003]

[Problems to be solved by the device]

 With this method of connecting the weir plates to each other by the binding line, the binding by the binding line is weak, and the sagging is caused by the weight of the fresh concrete cast in the formwork of the cross reinforcement part and the formwork of the method frame part. It was happening. This could impair the appearance of the entire structure. In addition, the binding work with the binding wire is extremely troublesome, and the construction period was lengthened.

The present invention has been made to solve the above problems, and provides a formwork that is easy to assemble and that is used for a slope protection structure that does not sag due to the weight of concrete. The purpose is to do.

[0005]

[Means for Solving the Problems]

 The formwork for slope protection structure according to the present invention uses a net-like material for the form plate and the cross reinforcing plate. Expanded metal plate is used for the cross reinforcing plate. For the cross reinforcing plate used for the cross reinforcement, the hooks are projected at both left and right ends, and the hooks protruding from one end are bent at an acute angle. This cross reinforcing plate is laid across the vertical and horizontal formwork so as to intersect the formwork plate, the bent hooking part is hooked on the mesh of the formwork plate, and the hooking part protruding to the other end is the other formwork. Insert into the mesh of the board. The four cross reinforcing plates surround the cross reinforcing portion.

Further, the hooking portion protruding from one end of the cross reinforcing plate is bent at an acute angle, and the hooking portion protruding at the other end is bent at an obtuse angle. This cross reinforcing plate is laid across so that it intersects the vertical and horizontal formwork plates, the hooked part bent at an acute angle is hooked on one formwork, and the hooked part bent at an obtuse angle is meshed on the other formwork. It can also be inserted alongside the formwork plate.

[0007] A reinforcing material is fixed to the cross reinforcing plate, both ends of this reinforcing material are projected from both left and right ends of the cross reinforcing plate as hooks, and the hooks are inserted into the meshes of the horizontal and vertical formwork plates. It is possible to hook.

【Example】

 Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings. In FIG. 1, both the cross reinforcing plate 1 and the mold plate 2 are made of expanded metal. Expanded metal is a reticulated material that is made by drawing a number of slits in a steel sheet and then stretching it. Hook portions 3 are fixed to the left and right ends of the cross reinforcing plate 1 by welding or the like, and the hook portions 3 at one end are bent at an acute angle. The cross reinforcing plate 1 is laid vertically and horizontally so as to cross the form plates 2 and 2 of the form frame 4 assembled. The hook portion 3 that is bent at an acute angle is hooked on the one mold plate 2. The hook portion 3 protruding at the other end is inserted into the mesh of the form plate 2. The four cross reinforcing plates are used to surround the crossing portions of the vertical and horizontal formwork 4, 4. 5 is a reinforcing bar arranged in the formwork 4/4. In this state, mortar 6, which is a cement-based hardening material, is placed in the mold 4 and in the space surrounded by the mold plate 2 and the cross reinforcing plate 1. Since both ends of the cross reinforcing plate 1 are hooked on the mold plates 2 and 2, the sagging does not occur even if the weight of the mortar 6 is applied.

As shown in FIG. 2, the hook portions 3 are slightly projected from the left and right ends of the cross reinforcing plate 1 made of expanded metal. The hook 3 protruding from one end of the cross reinforcing plate 1 is bent at an acute angle, and the hook 3 protruding from the other end is bent at an obtuse angle. The hook portion 3 bent at an acute angle of the cross reinforcing plate 1 is hooked on the mesh of one of the mold plates 2, and the hook portion 3 bent at an obtuse angle of the other end is inserted in the mesh of the other mold plate 2 to form a mold. Place along the frame plate 2. As a result, neither of the hook portions 3 on both ends protrudes inside the form 4, and the bar arrangement of the reinforcing bar 5 is not hindered.

FIG. 3 shows a case in which flat reinforcing members 7 are fixed to the cross reinforcing plate 1 by welding or the like, and both left and right ends thereof are adopted as the hooks 3.3. This is hooked on the mesh of the form plates 2 and 2 of the horizontal and vertical form frames 5.5. Since the reinforcing members 7 and 7 reinforce the cross reinforcing plate 1 and the labor for fixing the hook portions 3 one by one can be omitted, the round rod-shaped reinforcing members 7 and 7 can also be adopted. In the embodiment shown in FIGS. 1 and 2, the hook portions 3 are separately fixed and fixed, but the continuous reinforcing member 7 as shown in FIG. 3 is fixed and both ends thereof are hooked by the hook portions 3 and 3. Can also be used as a bend

[0011]

[Effect of the device]

 The present invention has the above-mentioned configuration, and a cross-strengthening plate surrounds the crossing portion of the vertical and horizontal formwork, and a stiffening material is placed on it to reinforce it, thus constructing a strong slope protection structure. can do. Expanded metal is used as a cross reinforcing plate, and by hooking the protruding parts at the left and right ends, the reinforcing plate will not be displaced even by the weight of the hardened material. Therefore, the shape of the entire structure can be finished aesthetically. Also, the installation of the cross reinforcing plate is extremely easy and the construction period can be shortened. Further, by fixing the reinforcing material and projecting the left and right ends of the cross reinforcing plate with both ends as hooks, it is possible to save labor for reinforcing the cross reinforcing plate and attaching the hooks.
