2. Description of the Related Art Conventionally, as a formwork of this type, an actual flat 2-11
There is a concrete foundation stone formwork described in Japanese Patent No. 6538 and Japanese Utility Model Laid-Open No. 2-26240. This formwork has a peripheral frame shape provided with an opening of a frame body into which concrete is poured. Then, for example, in order to install a concrete foundation for a pipe support stand, a formwork should be installed in advance before constructing this stand, after which the stand is installed, and after the piping is finished on this stand, the formwork is completed. Concrete, mortar, etc. are poured into and used as it is as a foundation.

On the other hand, in the column base type foundation,
Used to form a recess for the hauling attachment at the top edge of the ram.
The column formwork used is described in Japanese Utility Model Publication No. 3-22359.
It is

[Problems to be Solved by the Invention] However, since the conventional formwork needs to be installed around the legs of the mount in advance before constructing the mount, it is forgotten to install the formwork. In this case, the installed pedestal must be lifted and installed, which is an inconvenient task.

Also, since a lot of work is done between the installation of the formwork around the legs of the gantry and the pouring of concrete into the formwork, careless contact with the formwork installed at the proper position is made. There is a risk that the installation position will be misaligned by doing so. Moreover, even if concrete flows into the formwork at a regular installation position, there is a case where the momentum of the concrete flows in causes a positional shift, and it was necessary to carefully and carefully perform the concrete inflow work.

On the other hand, it is used for a column-based foundation.
The column formwork can only be used for special column-based construction.
If possible, install around the foot of an already installed frame.
It is difficult to use it as a formwork. Ie this
Column formwork connecting means slide fit up and down
Parts are used, so the formwork is assembled after construction of the gantry.
When you try to do so, one of the formwork lifted up will hit the stand.
It may not be possible to connect them by contact .

Moreover, the mold is to be assembled from the side surface.
Then, pour concrete into the assembled formwork
Then, there is a problem that Toro flows out from this connection part.
Jijiru Therefore, this invention was devised to solve the above-mentioned problems, and it can be installed after construction of the gantry .
The purpose of the invention is to provide a resin base formwork that can prevent the spillage of the toro .

[0008]

In order to achieve the above-mentioned object, the present invention is a frame-shaped scrap frame for forming a concrete foundation, in which the frame body is vertically divided into a plurality of connecting bodies 1. This is because the joint 2 is divided and a joint 2 for connecting the connecting bodies 1 to each other from the side surface is provided in the divided portion.

The joint 2 is provided with a plug piece on the divided side edge of the connector 1.
2A and a locking hook 2B are provided, and the insertion piece 2A faces each other.
Horizontally inserted into the insertion recess 2a provided on the divided side edge of the connector 1.
In addition, the locking hook 2B is also connected to the opposite connecting body 1.
From the side to engage with the locking hole 2b provided on the divided side edge of the
To do .

Further, the connector 1 is provided with an adhesive recess 3 for applying the adhesive P on the bottom thereof.

Further, the frame body to which the connecting body 1 is connected is formed in a plane circular shape as means for solving the problem.

[0012]

In other words, according to the present invention, the plurality of frame bodies 1 are connected to each other by the joint 2 in a frame shape.

The joint 2 includes an insertion piece 2A and an insertion recess 2
a is to prevent the outflow of the toro, and the locking hook 2B and the locking hole.
The frame 1 is connected and fixed to each other by 2b.
It

The adhesive P applied to the recess 3 at the bottom of the connector 1 fixes the connector 1 to the floor or the like.

The frame members connected in a plane circular shape can be accurately arranged only by aligning the core of the frame member with the installation position.

[0016]

Embodiments of the present invention will be described in detail below with reference to the drawings.

Reference numeral 1 shown in the drawings is a connecting body which is formed of a plastic material and constitutes a side plate of the mold.
By connecting the connecting bodies 1 to each other with the joints 2, a frame-shaped mold is formed (see FIG. 1). Joint 2 in the illustrated example
Is the insertion piece 2A and the locking hook 2B on the divided side edge of the connection body 1.
The insertion piece 2A is horizontally inserted into the insertion recessed portion 2a provided on the divided side edge of the opposing connecting body 1, and the locking hook 2B is also a division of the opposing connecting body 1. The locking hole 2b provided on the side edge is horizontally locked and connected (see FIG. 2). By forming the joint 2 in this way, it becomes possible to mount the devised form from the side of the foot of the mount. Therefore, it can be mounted without being affected by a low pedestal or by a pipe installation base installed above the problem.

An adhesive recess 3 for applying the adhesive P is provided at the bottom of the connector 1. The adhesive recess 3 shown in the figure is the connection body 1.
The application piece 3A is formed so as to project from the bottom toward the inside of the frame, and the height of the application piece 3A is made slightly higher than that of the bottom of the connector 1 to form the adhesive recess 3 (see FIG. 3). At this time, the through hole 3 that vertically penetrates the coating piece 3A
When B is provided and the adhesive P applied to the lower surface of the coating piece 3A is pushed out to the upper surface of the coating piece 3A through the through hole 3B, a stronger fixing force can be obtained.

The frame body to which the connecting bodies 1 are connected is formed in a plane circular shape. Further, the frame body has a step portion 1A formed at a position that divides the height into two parts, and the lower portion is bulged more than the upper portion with the step portion 1A as a boundary. By forming in this way, the stability of the formwork and the foundation after concrete injection can be enhanced.

[0020]

The present invention achieves the original purpose by being configured as described above.

That is, since the frame body is vertically divided into a plurality of connecting bodies 1 and the joints 2 for connecting the connecting bodies 1 to each other from the side surfaces are provided, after the pedestal is constructed or the pipes are installed. Even if it is, it can be easily mounted around the legs of the gantry. As a result, there is no need to pre-install it around the legs of the gantry, and the possibility that the installation position will be misaligned due to the subsequent work is eliminated.

Moreover, the joint 2 is a divided side edge of the connector 1.
The insert piece 2A and the locking hook 2B are provided on the
Water is placed in the insertion recesses 2a provided on the divided side edges of the opposing connecting body 1.
Insert flat and the locking hooks 2B also face each other
Locks from the side surface to the locking hole 2b provided on the divided side edge of the connector 1.
After connecting the concrete, it will be connected.
Toro can be prevented from flowing out of the part .

Further, by providing the adhesive recess 3 for applying the adhesive P on the bottom of the connecting body 1, the connecting body 1 installed around the legs of the frame can be fixed. Therefore, not only unexpected contact but also displacement of the concrete due to the force of inflow is prevented, so that the installation can be accurately performed with a simple operation.

Further, when the frame body to which the connecting body 1 is connected is formed in a plane circular shape, the accurate arrangement can be achieved only by aligning the core portion of the frame body with the installation position. Therefore, for example, even when many concrete foundations are continuously provided along the pipe supporting frame, the appearance is extremely good.

As described above, according to the present invention, it is possible to mount the pedestal after the construction, and moreover, to wash the concrete.
You can prevent the Toro from flowing out from the connecting part after entering
Exhibits various effects practically useful, such as that.
