Detailed Description of the Invention A1. Purpose of the Invention [Industrial Application Field] This invention relates to concrete formwork used for the corner parts of structures, or corner parts of external walls, internal walls, retaining walls, etc. of buildings. It is also used privately as a finishing material.

[Prior Art 1] Currently, in the civil engineering and construction industry, construction work is delayed due to a shortage of formwork carpenters, and construction costs are rising accordingly. In order to solve this problem, the present applicant first filed Japanese Patent Application No. 1,513.
No. 21, Japanese Patent Application No. 2-11'3290, Japanese Patent Application No. 2-178
626 and Japanese Patent Application No. 2195335 (hereinafter referred to as the prior art), a formwork panel was proposed.

However, this prior art is a formwork panel on a straight line,
No proposals have been made for corner areas.

[Problems to be solved by the invention; The present invention solves the shortage of skilled workers, which is currently becoming a social problem,
Furthermore, it is an object (technical means) to further develop the above-mentioned formwork panel, which does not require skilled workers, and to provide a formwork panel that can be processed even at corners.

2. Structure of the invention [Means for solving the problems] In order to achieve the above object, the corner formwork panel of the invention adopts the following structure (technical means).

That is, the side plate 1 which is substantially rectangular is bent at a certain angle, or the side plate 1 is formed substantially bent by joining a plurality of side plates. What is the structure of the pillars 2 fixed on the side surfaces? Engagement tools 4 are fixedly installed at both upper and lower ends of the pillars 2 to connect the adjacent formwork panels B, and these are connected by means of connectors 3. Basically, two or more pillars are installed on the side plate at positions where the side plate is stable. The formwork panels installed facing each other are identified by separators 6 provided as necessary near the upper ends of the columns. Further, it is characterized in that horizontal crosspieces 5 are provided between the pillars as necessary depending on the installation situation of the side panels.

[Function] In constructing a wall using this bent formwork panel, each formwork panel is arranged in the vertical direction, and in the lateral direction, the bent formwork panel or the formwork panel E of the prior art of the previous application is arranged. (
(the side panels do not bend) and are fixed with horizontal crosspieces as necessary.

Therefore, even if the structure has an arbitrary shape, the folded formwork panel A and the formwork panel E of the prior art can be used in combination, making it possible to construct structures of various shapes.

[Example] An example of the bent formwork panel of the present invention will be described based on the drawings.

(First Embodiment) Figures 1 to 4 are diagrams of the first embodiment, and Figure 1 shows the assembly when the bent formwork panel A of the present invention is applied to a corner part as an example. In a perspective view, FIG. 2 shows formwork panel A in FIG. 1 combined with basic formwork panel C and adjacent formwork panel (
A perspective view of the assembled and laminated formwork panels including B and E) is shown.

FIG. 3 shows a cross section taken along line AA in FIG.

FIG. 4 is a detailed perspective view of the connection when the pillars are connected.

The folded formwork panel A of the present invention refers to a formwork panel including folded portions, curved portions, and corner portions of a construction.

Follow. The formwork panel A is used in combination with the formwork panel E of the prior art recently disclosed by the present applicant.

That is, the corner form panel A of the corner part is used for the corner part of the structure, and the form panel E of the prior art is used for the direct part.

If the horizontal building is located at a bend from a corner, corner form panel A and bend form panel B are used.

In Figure 1, the side plate is bent at almost a right angle at the center between the two supports of the inner formwork panel, and correspondingly, the two horizontal beams are also broken and fixed near the center in the horizontal direction. ing.

As described in the prior art, the formwork panel has one or more pillars fixed to a substantially rectangular side plate, and engaging tools 4 are fixed to the upper and lower ends of the pillars. The engaging tool engages with the engaging tool of the adjacent column. A separator is provided at any position of the support to connect the opposing support, or one or more places are provided for each support.
Install separators on every other and every two or more pillars. Also, the separator may be installed on the horizontal crosspiece. Also, horizontal crosspieces may or may not be provided depending on the shape of the formwork panel. If horizontal crosspieces are provided, one or more of them shall be provided between the formwork panels and the supports of adjacent formwork panels, or both.

The present invention is exactly the same as the technical concept of the formwork panel of the prior art described above, and the difference is that the side panels and horizontal crosspieces are bent as described above.

In the inside bent formwork panel shown in Figure 1, the side plate 1
It is bent almost at a right angle near the center of the side plate, and a support post 2 is glued to the side of the side plate near the center of the bend, and the cross section of the support post is a hollow rectangle, and its upper end is an engaging A recessed tool 41 is provided at its lower end with an engaging tool 4 of an engaging member 42. A separator hole 61 is provided near one end of the column, and a separator hole 61 is provided in the separator hole of the opposing column.
6 and tighten between the struts with a separator fastener 62.

Two horizontal crosspiece brackets 51 are fixedly installed near the upper and lower ends of the side surfaces in the long direction of the pillar, and two horizontal crosspiece main brackets are also fixed on the opposite side of the support. The ends of the horizontal crosspieces 5 are placed on the horizontal crosspiece supports and fixed with horizontal crosspiece submersible holes 52 such as bolts.

The horizontal crosspieces 5 at the bent portions of the side panels are bent horizontal crosspieces corresponding to the side panels.

The preferred materials for the side planks and supports are wood, hennium, plastic, iron, aluminum, etc., or other materials may be used as long as they are suitable for the purpose of the formwork panel.

The opposing bent panel A° has side plates, supports, and horizontal crosspieces like the formwork panel A, and the bending position of the side plate is also at a position opposite to the formwork panel A. The frame panel A and the opposing formwork panel A° have similar shapes.

The difference in the folding formwork panel A° is that the width of the side plates between the supports is longer, and if the concrete placement pressure cannot be handled, supports are installed near the bends of the side plates as necessary. In this case, the horizontal crosspieces also connect the supports in the same manner as described above. Since the separator 6 in this case does not have opposing supports, it is connected and tightened with the horizontal crosspieces.

In this way, the installation location of the separator is not limited to only between each support, but may be installed between each horizontal crosspiece or between a horizontal crosspiece and a support, depending on the situation at the site.

As for the construction method, folded formwork panels C for the foundation will be installed on site.

The structure of the formwork panel C, as shown in Fig. 2, is that it is fixed to the lower end of a rectangular plate or support, the height of the support and side plate is short, and there is one horizontal crosspiece. Install the opposing formwork panel C°, which is bent near the center, and install the other adjacent formwork panels. After installation, the separator 6 is passed through the separator hole and temporarily tightened with a fastener 62.

Next, the engagement members 42 of the bent formwork panel A are fitted into the engagement recesses 41 of the formwork panel C.

In FIG. 4, the connecting penetration hole 32 provided in the engagement member 42 of the formwork panel A and the connection penetration hole 32 of the engagement recess 41 of the formwork panel C match after fitting, so this hole Then, the connecting ring 31 of the connecting tool 3 is compressed, and then the connecting wedge 30 is driven into the connecting horizontal hole 33.

Since the connecting rod 301 is fixed at the end of the connecting ring,
The five engaging tools and the engaging concave tool are sufficiently tightened after being fitted and will not come off even under concrete pouring pressure and vibration. In this way, other adjacent formwork panels are also masonry and connected in a similar manner.

Separators are temporarily tightened after each masonry or after masonry is completed.

After the masonry is completed, concrete 7 is poured between the formwork panels.

The side plates receive the concrete casting pressure, and the pressure is transmitted to the horizontal beams, supports, and supports. The separator takes care of the swelling of the pillar. The vertical stress is borne by the pillars, and the horizontal stress is borne by the crosspieces.

As described above, the formwork panel of the present invention can fully achieve its purpose by allocating functions and configuring each member.

After the concrete has hardened, the formwork panels are removed in the reverse order of the masonry method.

(Second Example) As mentioned above, structures have various shapes such as bends, but it is currently difficult to create formwork panels that match the shape of horizontal structures due to the lack of craftsmen. Have difficulty. There is a need for a product that saves the labor of craftsmen as much as possible, even when it comes to bends and corners.

The present invention is based on the idea of the invention of the first embodiment described above,
The purpose is to provide an invention that requires as little craftsmanship and time as possible.

The difference between the present invention and the first embodiment is that connecting hinges 8 (hinges used in construction, etc.) are fixed to both formwork panels at positions where bending is required between the supports of the formwork panels. This allows for free bending angles.

Figure 5 is a perspective view of a formwork panel with a connecting hinge of the present invention, Figure 6 is a perspective view of a connecting hinge, Figure 6 (a) is a perspective view of a known hinge, and Figure 6 (b) is a perspective view of a connecting hinge. Figure 6(c) is a perspective view of the hinge blade embedded in the side plate, and Figure 6(c) is the hinge blade 8.
1 is exposed from the side plate and a deformable material is filled between them.

FIG. 7 shows a perspective view of the folding formwork panel when folded as shown in FIG. 54.

In FIG. 5, since a hinge 8 is fixed near the center of the side plate 1, the side plate can be bent freely.

A post 2 is fixed to the side plate near the center of each side plate on each side across the hinge.

A horizontal crosspiece support 51 is fixedly installed near the top and lower end of the support, and a horizontal crosspiece 5 is installed on one side of the support.

The reason why there is no horizontal crosspiece on the center side of the side plate is because the horizontal crosspiece is attached after the side plate is bent, so the horizontal crosspiece is installed according to the bending angle depending on the situation at the site, and the horizontal crosspiece is installed. It is fixed to the receiver 51 with horizontal crosspieces 52 such as bolts.

The folded form panel is shown in FIG. The method for installing the central bent horizontal crosspiece during construction may be to install it after fitting the support to the adjacent formwork panel [7]. Alternatively, it may be installed before the strut is fitted.

FIG. 6(a) shows a hinge used in a known door, and this hinge 8 is used for the side panel.

FIG. 6(b) shows a case where the hinge blade 81 is provided near the center of the thickness of the side plate, and the hinge is provided over the entire vertical width of the side plate.

If you do this, the concrete will get into the hinges and make the structure rough. If this is a concern, it is a good idea to cover the concrete with a thin, flexible material such as plastic or rubber. This flexible material 9 is represented by a dotted line.

Fig. 6(c) shows a case where the hinge is partially attached to the side plate and the blades 81 are exposed on the surface of the side plate, and the gap between the hinges is filled with a construction material 9 made of deformable material such as rubber or plastic. Install it to prevent concrete from leaking.

The method of using the bent formwork panel of the present invention is not limited to concrete formwork, but the use of the bent formwork panel can be expanded by burying the formwork panel.

That is, the conocrete side of the side plate 1 of the formwork panel described above is used as the decorative surface, the supports and horizontal crosspieces are set as the concrete side, and the side plate, supports and horizontal crosspieces are buried and used for concrete walls and pillar materials. I can do it.

Also, since it can be used as part or all of conventional reinforcing bars for columns and crosspieces, it will help with the recent shortage of reinforcing bars and formwork workers.

Note that the cross-sectional shapes of the pillars and crosspieces of the first and second embodiments and the decorative boards described above are not limited to rectangular shapes, but can be of any cross-sectional shape such as circular or L-shaped depending on the purpose of the structure.

The invention of using the side panel as a decorative board can also be applied to the prior art described above.

1.8 Effects of the Invention According to the first embodiment of the present invention, the side panels are bent at the factory or on site to match the shape of the bent portion, the support columns are fixed, and the horizontal crosspieces are installed as necessary. are installed in factories and on-site, so most of them are made in bent formwork panels or factories. Therefore, even an amateur can assemble and install it on-site.According to the second embodiment, hinges and other structures are provided at arbitrary positions on the side panels, so it can be assembled and installed on-site.
＼It can handle any type of bent structure, so construction can be done quickly.

In addition, the present invention can be used as a decorative board, and also serves as a support and a horizontal crosspiece or reinforcing bar, so it is very useful in solving the shortage of craftsmen.
