Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for easily forming a mold by arranging a frame plate when constructing a basic concrete for a house or the like.

[0002]

2. Description of the Related Art FIG. 6 shows a conventional formwork structure. This formwork structure consists of plywood (a) and (a) arranged side by side at a specified interval.Therefore, a bottom frame (b) with both ends standing vertically is placed on the ground. The lower ends of the veneer plates (a) and (a) are fixed to the bottom frame (b). And plywood (a),
The upper plate (c) is passed to the upper end of (a) and is nailed, and both veneer plates (a) and (a) stand upright while maintaining parallel to each other. Concrete is poured into the space between both plywood (a) and (a).

When the poured concrete has hardened, the veneer boards (a) and (a) are removed, and another rise is created on the base of the created concrete foundation. Veneer boards are installed side by side to make a stand-up formwork. By the way, the conventional work of assembling the formwork is very troublesome and can be reused by using the veneer plate as a frame plate, but the cost is also high. Creating the base of the basic concrete and then forming the rising on the base requires about 2 man-hours for the production of the formwork and the pouring of the concrete, as compared with the case of creating the basic concrete at once. It will be doubled.

[0004]

As described above, the conventional formwork structure has the above problems. The problems to be solved by the present invention are these problems, and provide a formwork structure capable of simultaneously forming a base and a rise, and a formwork structure capable of easily assembling the formwork. In particular, the present invention provides a holder for a frame plate for constructing a mold structure, which has a structure that saves labor for mounting the frame plate.

[0005]

The formwork structure of the present invention is constructed so that the base and the rising of the foundation concrete can be constructed at the same time. Then, a frame plate holder is used to form the mold, and a predetermined mold can be easily assembled only by setting the frame plate in the frame plate holder. In this case, a stand-up frame plate can be set on the holder, and the base frame plate is attached to a fastening tool connected to the reinforcing frame. By the way, in this formwork, a reinforcing bar which is a framework of the basic concrete is arranged. As the reinforcing bar, a "reinforcing frame for wooden house foundation" according to No. Kaikai 3-29538 is used.

The holder has a support plate for holding the stand-up frame plate, and has a structure capable of adjusting the height of the support plate. The base plate and the bar member are attached to the lower end of the holder for rising so as not to fall, but a plurality of holders are connected at regular intervals instead of being an independent body one by one.

A connecting member such as a connecting rod (connecting bar) is used as the connecting means of the holder and is welded to the base plate or the bar material. Further, in the present invention, a steadying member is attached so as to connect both the support tools so that the support plate for holding the rising frame plate does not swing. Of course, the steady rest does not have to be mounted between all the supports, but may be provided at a suitable place.

On the other hand, the base frame plate is connected to the horizontal frame side portion of the foundation building streak frame, and is attached to this horizontal fastener. The fastener has an engaging portion for engaging with a lateral line of the horizontal frame, and also forms a fitting portion for attaching the base frame plate. The locking portion is a concave groove into which a lateral line fits, or is provided at an arm end extending from the fitting portion, and an L-shaped receiving portion is formed on the opposite side of the fitting portion. A crosspiece is set in the receiving portion and supports the base frame plate fitted and attached to the fitting portion. Of course, when the base frame plate is strong, the crosspiece is not necessary, and therefore the receiving portion may be omitted.

By the way, in the formwork structure of the present invention, a frame having a plurality of holders is arranged at predetermined intervals, and a standing frame plate is set on these holders to form a formwork. Then, a base frame plate is attached to the fastener connected to the horizontal frame of the foundation building streak frame, concrete is poured into the rising formwork, and concrete accumulated between the frame plates for the base is the base of the basic concrete. , The concrete held between the one rising frame plate can be built up at once without building the base and rising separately. In this case, the height of the rising frame plate is adjusted by adjusting the support plate. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

Can be obtained.

[0019]

According to the formwork structure of the present invention, since the frame plate holder is used, the setting of the frame plate is very simple, and the formwork can be installed in a short time. In addition, since the frame plate holder has a plurality of legs attached to the connecting member at regular intervals, the work of arranging it on the ground is easy, and it is not necessary to position the support member, and the frame plate holder is accurately arranged. You can Then, a support plate is attached to the support bolt of the support, but the support bolt is passed through the bolt hole formed in the support plate and the level is made simply by tightening with the thumbscrew, and the leveling is easy. Fixed.

Further, the base and the rising of the basic concrete can be formed at the same time, and the labor saving can be significantly reduced as compared with the conventional work. Further, in this frame plate holder, since the height of the holding plate for holding the rising frame plate can be freely adjusted, the rising frame plate can be arranged according to the height of the base. Furthermore, since a steadying member is provided on the support attached to the connecting member as needed, the support and the rising frame plate are accurately positioned without swinging. On the other hand, the support plate is provided with a fastening piece and a locking piece on both sides so that the rising frame plate does not rise and come off due to the buoyancy of concrete poured into the formwork.
