[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support for supporting opposite left and right concrete forms at a base end of a concrete wall having a predetermined concrete space when a concrete wall having a predetermined width is constructed. Things.

[0002]

2. Description of the Related Art Conventionally, there is a support as shown in FIG. 5 for supporting a concrete formwork with a predetermined concrete driving space therebetween when constructing a concrete wall having a predetermined width. This known support (C) is formed by bending a strip-shaped thin metal plate (13), and the left and right side plates (14),
(14) and the intermediate rising pieces (15) and (15) sandwich one end of the formwork (B), thereby supporting the left and right formworks (B) and (B) at a predetermined interval. It has become.

[Problems to be solved by the invention]

[0003] In this known support (C), after removing the formwork by applying concrete, the side plate (14) and a part of the horizontal plate are exposed to the outside. They are leveled and buried with mortar or cement to hide them. However, the gap between the side plate (14) and the constructed concrete wall is so narrow that it is difficult to strike outward with a hammer and the concrete wall is damaged, and the work of embedding the remaining flattened portion with cement is troublesome. It is.

Accordingly, an object of the present invention is to enable the left and right concrete forms to be reliably supported at predetermined intervals during concrete construction, and to easily remove a residual portion exposed to the outside after concrete construction. Thus, a support for a concrete formwork is provided.

[0005]

Means for Solving the Problems In order to achieve the above object, the present invention takes the following technical means. That is, the support for the concrete formwork according to the present invention is an integrated press-formed product made of a thin metal plate material, and a strip-shaped horizontal plate member (1) having an appropriate width and the horizontal plate member. (1) Side plate portions (2) and (2) bent upward at right angles from both ends, and rising pieces provided at predetermined intervals near both ends of the horizontal plate member (1). (3),
(3), wherein the distance between the rising piece (3) and the side plate portion (2) adjacent thereto is formed to have a dimension substantially equal to the thickness (L) of the formwork (B). Upper piece (3), (3)
A perforation (4) for facilitating the cutting is formed along the width direction of the horizontal plate member (1) at the bent base end portion of the side plate portion (2), and (2) . Is a tool such as a bar
Into the perforation
(4) The outer part is bent upward and cut off.
It has a structure in which a tool insertion hole (5) for removing is provided.

[0006]

[Function] As shown in FIG. (4), the support (A) configured as described above fixes the horizontal plate member (1) to the base body (2) through appropriate means such as nailing, The side plates (b) of the concrete forms (B) and (B) are fitted between the rising pieces (3) and the side plates (2), and the left and right forms (B) and (B) It is kept separated by the concrete driving space. After concrete construction,
After removing (B), insert a tool such as a bar from the tool insertion hole (5) and pry up the side plate parts (2) and (2) together with the end of the horizontal plate member exposed to the outside, The exposed part of the support can be easily cut off from the perforations (4).

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the embodiments shown in FIGS. In the drawings, reference numeral (A) denotes a support for a concrete formwork according to the present invention, which is integrally formed by pressing a thin metal plate. This support (A) includes a horizontal band-shaped horizontal plate member (1) having an appropriate width, and side plate portions (2) and (2) bent upward at right angles from both ends of the horizontal plate member (1). ), And rising pieces (3) and (3) which are stamped and erected at predetermined intervals from each other near both ends of the horizontal plate member (1). The horizontal plate member (1) and the rising pieces (3), (3) and the side plate portion
In (2), (2), a plurality of reinforcing ribs (6), which are curved in a semicylindrical shape, are formed along the length direction to increase the bending strength.

The rising piece (3) and the side plate (2) adjacent thereto
As shown in FIG. 4, the gap is substantially equal to the thickness (L) including the side plate (b) of the mold (B). The rising pieces (3), (3) are formed at intervals substantially equal to the width of the concrete to be constructed. Further, the rising piece (3),
Perforations at the base end of (3) to facilitate cutting
(4) is formed along the width direction on the back surface of the horizontal plate member (1). In the present embodiment, V cuts (9) and (9) are provided on both sides of the horizontal plate member (1) on the line of the perforation (4) to further facilitate cutting. May not be required. Further, an insertion hole (5) for inserting a rod-shaped tool is provided in the center of the lower part of the side plate portions (2), (2).

In the embodiment shown in the figures, the side plate portions (2), (2) are formed with a hooking piece (8) which is divided so as to be easily bent by two slits (7), (7). ing. The entrances of the slits (7), (7) are slightly widened so that the hook piece (8) can be easily folded. The metal plate material of the support shown in the example is 1.6 mm, and the support is formed with a total length of 220 mm and a width of 34 mm. And it is changed according to the form dimensions.

The support (A) configured as described above is shown in FIG.
As shown in, fixed to the base body (12) with nails (11) through holes (10) provided in the horizontal plate member (1), concrete formwork (B),
The side plate (b) of (B) is fitted between the rising piece (3) and the side plate part (2), and the locking piece (8) is bent inward to lock the formwork side plate (b). Then, the left and right formwork (B), (B) are held with a predetermined concrete driving space. After concrete construction, raise the retaining piece (8), remove the formwork (B), (B), insert a tool such as a bar from the tool insertion hole (5), and insert the side plate (2),
By prying (2) together with the end of the horizontal plate member exposed to the outside, the exposed part of the support is easily perforated.
It can be cut and removed from (4).

Although the representative embodiment of the present invention has been described above, the present invention is not necessarily limited to the structure of the above embodiment. For example, the above perforation for cutting
(4) can also be formed by corrosion lines or V-grooves, and these configurations are also included in the perforation (4). In addition, the Kamaboko-shaped reinforcing rib (6) shown in the above embodiment.
It is also possible to omit the hooking piece (8) divided by the slits (7) and (7) of the side plate portion. In addition, the present invention can be implemented by appropriately changing the range within a range having the constituent requirements and having an effect.

[0012]

[Effects of the Invention] Since the support of the present invention is constructed as described above, after the concrete work, after removing the formwork, a tool such as a bar is inserted from the tool insertion hole and the side plate portion is inserted. By prying up with the end of the horizontal plate member exposed to the outside, the exposed portion of the support can be easily cut and removed from the perforation, and thereby, the side plate portion exposed to the outside can be removed as in the related art. It is possible to omit troublesome work such as striking outward with a hammer and leveling it, embedding it with mortar or cement and finishing it beautifully without damaging the concrete wall, Since it is an integrated press-formed product made of thin plate material, it can be manufactured at low cost.
There is a remarkable effect.
