Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a concrete-embedded formwork used in facilities such as a legal frame for the protection of sloping ground.

(Prior Art) Conventionally, as a work for protecting the slope of a sloping ground, a concrete frame is installed. For the construction of this method frame, a method of using an embedded formwork made of wire mesh, which has good workability, is often used instead of the method using a general temporary formwork. Those using this embedded formwork are, for example, as shown in Japanese Utility Model Publication No. 54-21844 and Japanese Patent Publication No. 56-9622, those in which opposing mesh formwork plates are connected by a spacer are installed in the ground. After that, the main feature is that the main bars are assembled between the mesh form plates.

(Problems to be Solved by the Invention) The above-mentioned conventional embedded formwork has an advantage that it is easy to install the embedded formwork at a predetermined position. Since the assembling is performed after the embedded formwork is installed, the formwork and the spacers obstruct the work, which makes the work of the formwork less efficient.

The present invention was made in order to solve the above-mentioned conventional drawbacks, and the reinforcing bars such as the main bars are first assembled, and the embedded formwork is securely and easily operated at the predetermined positions with respect to the pre-assembled reinforcing bars. It is intended to be able to be installed in, so that efficient formwork construction can be performed.

(Means for Solving the Problems) Regarding the configuration of the present invention for achieving the above object,
The present invention will be described with reference to the drawings corresponding to the embodiments. According to the present invention, one side surface of a mold plate 1 made of mesh is provided with a required space in each of a length direction and a height direction of the mold plate 1. , The joint members 4 and 4 that engage with the reinforcing bars installed in advance in the natural ground are rotatably attached in the vertical direction, and the joint members 4 and 4 are connected in series in the length direction of the form plate 1. It is characterized by being connected by the connecting rods 9 and 10.

(Operation) Since the present invention is constructed as described above, the form plate 1
The more protruding joint members 4 and 4 have the protruding portion 5 vertical as shown in FIG. 2 from the use posture in which the protruding portion 5 is in a horizontal state as shown in FIG. It will be possible to freely rotate to the folded posture in the state. Since the connecting members 4 are connected by the connecting rods 9 and 10, the connecting members 4 and 4 connected in series in the lengthwise direction of the form plate 1 are interlocked with each other and have a high strength structure.

When storing or transporting the formwork, the joint members 4, 4 should be folded as shown in FIG. 2 to reduce the protruding length of the joint member 4,
In use, the joint member 4 is brought into a protruding state as shown in FIG. 1, and the bent portion formed by the protruding portion 5 corresponding to the tip end portion of the joint member 4 and the leg portion 7 is hooked on the main bar 13.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes an embedded formwork plate, which is formed by connecting a number of vertical lines 2, 2 and horizontal lines 3, 3 in a mesh. As the material of the vertical wire 2 and the horizontal wire 3, iron wire material, reinforced paper, glass fiber, plastic material or the like is applied.

On one side surface of the form frame plate 1, a joint member 4 for engaging a reinforcing bar such as a main bar installed in advance of the form frame plate 1,
4 is installed. The joint members 4, 4 are attached to the horizontal line 2 which is a constituent member of the mold plate 1 at predetermined intervals in the upper and lower parts of the mold plate 1 in the length direction of the mold plate 1. And is vertically rotatable.

Each joint member 4 is formed in a U-shape by bending a rod made of a reinforcing bar, a plastic material, or the like, and providing leg portions 6 and 7 that are bent at substantially right angles in the same direction at both ends of the protruding portion 5. An engaging portion 8 is formed on the distal end portion of one leg portion 6 by winding it around the horizontal wire 2. The joint members 4, 4 attached to the upper portion of the form plate 1 and the joint members 4, 4 attached to the lower portion of the frame plate 1 are leg portions 6, 4 in the same posture.
6 and the protrusions 5, 5 are connected by connecting rods 9, 10. Therefore, the joint members 4 and 4 joined at the upper and lower portions of the form plate 1 are integrally rotated via the connecting rods 9 and 10, respectively, and the projecting portion 5 in FIG. 1 is oriented horizontally. The mounting posture can be changed from the used state to the folded state in which the protruding portion 5 in FIG. 2 is oriented in the vertical direction.

Next, in using the formwork of the present invention constructed as described above, first, the rebar assembly on the natural ground 11 is preceded. Third
As shown in the figure, an anchor 12 is driven into the natural ground 11, and a required number of main bars 13 and 13 are arranged at a required interval and joined by a hoop bar 14 to form a reinforcing bar assembly 15. in this case,
Reinforcing bar assembly by connecting reinforcing bar assembly 15 and anchor 12, etc.
Set 15 to the required ground clearance. Then, as shown in FIG. 1, the connecting members 4, 4 of the formwork plate 1 are arranged such that the projecting portions 5 are in the horizontal direction, and the leg portions 7 are hooked on the main bar 13, so that both sides of the reinforcing bar assembly 15 are attached. The form plates 1 and 1 are attached, and the joint member 4 and the main bar 13 are bound and fixed with an iron wire or the like.

Since the above-mentioned formwork is formed as a standard length product suitable for transportation, when the method frame to be constructed is long, the formwork is arranged in the length direction. At that time, since each formwork is installed by being connected to the main bar, it is not necessary to connect the formwork members.

After the formwork is installed, concrete 16 such as concrete or mortar is placed or sprayed, and the formwork and the rebar assembly 15 are embedded in the concrete 16 to establish the legal framework. .

(Effects of the Invention) As described above, the formwork of the present invention has one side surface of the formwork plate made of mesh, with a required space in each of the lengthwise direction and the heightwise direction of the formwork plate. Since the joint member that engages with the reinforcing bar that was installed in advance in the natural ground is rotatably attached in the vertical direction, and the joint members that are connected in series in the length direction of the form plate are connected by the connecting rod, There are many advantages like.

(1) Since the joint member that engages with the main bar is projected and attached to the form plate, it is easy to assemble the form frame to the bar arranged by the rebar pre-assembly, and therefore, as in the conventional case, Compared with the method of assembling the rebar after the formwork is installed, the rebar is easily assembled and the formwork can be easily installed, and the workability is remarkably improved, and it is particularly suitable for construction on a sloped ground with poor scaffolding.

(2) Since the formwork can be installed by engaging with the main bar, it does not require many spacers as in the conventional case, and the position setting of the formwork is easy and reliable, and the cover of the regular size of concrete is not covered. Can be secured.

(3) Since the joint members are rotatably attached and can be folded into a state in which the protruding length is small, it is convenient for transportation and storage, and since each joint member in series is connected in series,
Easy to rotate.
