Description

[Detailed description of the invention] <Industrial field of application> This invention involves assembling and forming a concrete pouring surface of a required area by arranging, stacking and connecting multiple concretes of the same shape and size in multiple rows and stages. There is no need to form continuous straight joints in either the above-mentioned juxtaposition direction or stacking direction in the concrete formwork at the site. Reduces the burden on components, simplifies and streamlines formwork assembly work,
End concrete used by connecting to the horizontal assembly direction ends of regular hexagonal or approximately regular hexagonal concrete formwork, which is effective in contributing to reductions in construction costs, when assembled and fixed. Regarding formwork. Specifically, a plurality of hexagonal concrete formworks in which circumferential side plates for overlapping and fixing are fixed and continuous around the entire outer edge of a regular hexagonal or approximately regular hexagonal flat plate in a posture perpendicular to the plate surface of the flat plate. The present invention relates to an end concrete formwork for filling in irregularities formed at the ends in the horizontal assembly direction and finishing the outer edges in a straight line when the concrete is assembled and fixed.

<Prior Art> The hexagonal concrete formwork as described above was first developed by the inventor of the present invention, and has already been disclosed and put into practical use as seen in Japanese Patent Publication No. 58-51807. However, to date, when hexagonal concrete formwork is arranged side by side or stacked in multiple rows or stages and connected, it is necessary to fill in the unevenness formed at the horizontal ends and to finish the outer edges in a straight line. A dedicated end formwork has not been developed, and as a means for finishing the end part, a hexagonal concrete formwork 3 cut into two halves along one diagonal line is used as a means for finishing the ends. A trapezoidal concrete formwork 06 is prepared separately, and this trapezoidal concrete formwork 06 is fitted into the recess formed by the hexagonal concrete formwork 3 and connected, and the outside edges of this trapezoidal concrete formwork 06 and the hexagonal concrete formwork 3 are A method was adopted in which a linear support member 07 was applied in the vertical direction to fixedly connect the support member 07.

<Problems to be solved by the invention> When using the conventional edge treatment method as described above, the area formed between the top and bottom of the hexagonal concrete formwork,
Not only is it necessary to manufacture and prepare two types of end treatment members: the trapezoidal concrete form that fills the recess corresponding to the hexagonal bisect shape, and the support member that will serve as the vertical column, but it is also necessary to prepare the two types of end treatment members on-site. The problem was that the number of fixed connections between parts increased, making the work that much more difficult.

<Means for Solving the Problems> In view of the above circumstances, the present invention makes it possible to fill a recess and form a vertical through column by connecting only a single member, and eliminates the need for the end portions required when assembling a hexagonal frame. The purpose is to provide an end concrete formwork that can be processed with very good workability, and in order to achieve this purpose, the end concrete formwork according to the present invention has a hexagonal flattened shape in the hexagonal concrete formwork. A rectangular plate having a length equal to the length of the cut diagonal line plus the length of one side of the hexagonal flat plate and an appropriate width on the cut edge side of a plate portion in which a flat plate is cut into two equal parts along one diagonal line. A flat plate made by integrating a series of parts, a flat plate made by dividing it into two parts, or a flat plate made by connecting two parts, has a posture perpendicular to the surface of the flat plate on the entire outer periphery of the flat plate. The structure is characterized by the fixed circumferential side plate being fixed and continuous.

<Function> The end concrete formwork according to the present invention having the above-mentioned characteristic configuration is formed by assembling and connecting hexagonal concrete formworks in multiple rows and stages in parallel, stacked and connected to form a concrete pouring surface of the required area. In this state, a plurality of pieces are stacked vertically with the bisected plate part fitted into the recess formed between the upper and lower hexagonal concrete forms at the horizontal end thereof, By fixedly connecting the upper and lower sides to each other via their circumferential side plates and to the hexagonal concrete formwork, it is used to form a concrete pouring surface whose outer edges are finished in a straight line up and down. It is.

<Example> An example of the present invention will be described below in detail based on the drawings.

In FIGS. 1 and 2, 3 is a hexagonal concrete formwork, which is placed around the entire outer edge of a regular hexagonal flat plate 1 in a position perpendicular to the surface of the flat plate 1 for superimposition and fixing. The peripheral side plate 2 is formed by bending the peripheral side plate 2 so as to be integrally fixed and continuous, and the peripheral side plate 2 is formed with bolt holes 2a for fixed connection. Reference numeral 6 denotes an end concrete formwork, which includes a trapezoidal plate portion 4a obtained by cutting the regular hexagonal flat plate 1 of the hexagonal concrete formwork 3 into two halves along one diagonal line, and a length of the cut diagonal line. A rectangular plate portion 4b having a length l ₁ plus the length l ₂ of one side of the regular hexagonal flat plate 1 (l = l ₁ + l ₂ ) and an appropriate width h, and a rectangular plate portion 4b having an appropriate width h. On the cut edge side, there is a flat plate 4 integrated in a series in a rotationally symmetrical state with the center of symmetry being bisected in the longitudinal direction of the cut edge, and on the entire outer periphery of the flat plate 4. It is constructed by integrally fixing circumferential side plates 5 that are perpendicular to the plate surface of the hexagonal concrete formwork 3 and have the same protrusion as the circumferential side plates 2 of the hexagonal concrete formwork 3, and the circumferential side plates 5 is formed with a fixing connection bolt 5a.

FIG. 3 shows that the hexagonal concrete formwork 3 is arranged and stacked in multiple rows and stages, and the peripheral side plates 2 are fixedly connected to each other via bolts and nuts 8 to cover the required area of concrete pouring surface. It is in the assembled and formed state, and by assembling and connecting a plurality of the above-mentioned end concrete forms 6 vertically at the ends in the assembly direction as explained in the <Operation> section above, a vertical straight line is formed. It has an outer end side of , and is treated to close the end so that it also serves as an end support column.

4 to 7 show modified examples of the end concrete formwork 6, and the one shown in FIG. 4 shows the rectangular plate portion 4 constituting the flat plate 4.
The one shown in FIG. 5 is one in which the cut edge of the plate portion 4a, which is cut into two halves, is biased toward only one side in the longitudinal direction, and is integrated in a series, as shown in FIGS. 1 and 2. The flat plate 4 shown in FIG. 6 is divided into two halves, and the circumferential side plate 5 is fixedly connected to the entire outer periphery of the flat plate 4'. A double type in which a circumferential side plate 5 is fixedly connected to the entire outer periphery of a flat plate 4″ that is integrally connected to the
The one shown in the figure is of a double offset type, in which two of the offset type shown in FIG. 4 are integrally connected one above the other. Furthermore, in any of the above embodiments, reinforcing ribs 9 may be appropriately provided as shown by imaginary lines to increase the strength.

<Effects of the invention> As can be understood from the detailed description above, the end concrete formwork according to the invention can be assembled in a state in which continuous straight joints are not formed. In terms of workability, when assembling formwork is constructed using hexagonal concrete formwork, which can be expected to have very excellent practical effects as mentioned above, unavoidable damage occurs at the ends in the horizontal assembly direction. It serves both as a member for filling the formed unevenness and revealing a vertically straight outer edge, and as a vertical through-post for receiving and supporting the formwork group located at the end. Compared to the conventional example described above, only one type of end treatment member is required, making it easier to manage the parts on site, and reducing the number of fixed connections, resulting in a significant improvement in overall work efficiency. be.
