By the way, the conventional assembly work of a formwork is very troublesome and can be reused by using the above-mentioned veneer plate as a frame plate, but the cost is also increased. In addition, when the foundation of the foundation concrete is created and then the rising is created on the base, the man-hour required for the production of the formwork and the pouring of the concrete is about 2 times compared to the case where the foundation concrete is created all at once. It will be doubled.
[0004]
[Problems to be solved by the present invention]
Thus, the conventional formwork structure has the above-mentioned problems. The problems to be solved by the present invention are these problems, and provide a formwork structure that can form a base and a rise at the same time, and can easily assemble the formwork. In particular, there is provided a frame plate holder for constructing a formwork structure, which has a structure that saves labor in attaching the frame plate.
[0005]
[Means for Solving the Problems]
The formwork structure of the present invention is constructed so that the base and rise of the basic concrete can be created at once. A frame plate holder is used to form the mold, and a predetermined mold can be easily assembled by simply setting the frame plate. In this case, a rising frame plate can be set on the holder, and the base frame plate is attached to a fastening device connected to the muscle frame. By the way, a reinforcing bar which is a framework of the foundation concrete is disposed in this formwork, and the “rebar frame for building a wooden house foundation” according to Japanese Utility Model Publication No. 3-29538 is used as the reinforcing bar.
[0006]
The holder has a support plate for holding the rising frame plate, and the height of the support plate can be adjusted. In addition, a base plate and a bar member are attached to the lower end of the holder for rising so as not to fall down, but a plurality of holders are connected at regular intervals instead of one individual body.
[0007]
A connecting member such as a connecting rod (connecting bar) is used as a connecting means for the holder, and is welded to the base plate or bar material. Further, in the present invention, the steadying member is attached so as to connect the two support members so that the support plate for holding the rising frame plate does not swing. Of course, the steady rest member does not need to be attached between all the supports, and may be provided at an appropriate place.
[0008]
On the other hand, a base frame board connects a fastening tool to the horizontal frame side part of the muscle frame for foundation construction, and is attached to this fastening tool. The fastener has a locking portion for locking to a side stripe of the horizontal frame, and forms a fitting portion for attaching a base frame plate. The locking portion is a concave groove into which the side stripe 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 that is fitted into the fitting portion and attached. Of course, when the base frame plate is strong, a crosspiece is not required, and therefore there is no need for a receiving portion.
[0009]
By the way, the formwork structure of this invention arrange | positions the flame | frame which has a some holder at predetermined intervals, sets a frame plate for a standup to these holders and comprises a formwork. A base frame plate is attached to the fastening device connected to the horizontal frame of the foundation building reinforcement frame, and concrete is poured into the above-mentioned rising frame, and the concrete accumulated between the base frame plates is the base concrete base. The concrete held between the rising frame plates can be built up at the same time without forming the base and the 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.
