Description

[0001]
[Technical field to which the invention belongs]
In the present invention, for example, a separator used in the foundation work of a wooden building is laid on a bottom base portion of a solid foundation in which concrete is placed in the entire area under the floor, which is one of the ant-proof and earthquake-proof foundations. Shape that can be removed from the concrete and reused after the part is cured.
[0002]
[Prior art]
"Solid foundation" defined in Ministry of Construction Notification No. 1347 (May 23, 2000) was added to the structure of the foundation of wooden buildings. Many "solid foundations" are being adopted for ground with a soil strength of 20KN or more.
The base part of this “solid foundation” is defined by the Building Standards Law from the viewpoint of health and must be exposed at least 50 mm above the ground. On the upper part of the foundation bottom plate, concrete is cast using a conventional embedded separator at the rising portion.
[0003]
As shown in design registration number 0989519, the conventional embedded separator has an inverted U-shaped cross section, so the bottom of the separator is about 3mm empty, and there is almost no strength and water resistance after concrete casting. ).
[0004]
Therefore, the foundation of a wooden building is made by exterior finishing, etc., usually by bending and removing the outer peripheral portion of the used separator and then mortar brushing finishing, but there are the following problems.
[0005]
[Problems to be solved by the invention]
In other words, non-waterproof embedded separators have little drainage of rainwater, and drainage work is carried out with buckets and small pumps every time it rains during construction until the construction of window glass and exterior finishes. Forced. In addition, if the building owner fills the outer periphery of the foundation by 50 mm or more in the kitchen garden after moving in, the rainwater often flows back under the floor and becomes unsanitary.
[0006]
Also, if the building owner fills the outer periphery of the foundation by 50 mm or more in a kitchen garden after moving in, rainwater will often flow back under the floor and become unsanitary.
[0007]
The foundation exterior mortar finish etc. peels off due to deterioration and vibration caused by minor earthquakes.
[0008]
Furthermore, conventional foundation exterior finishing, etc., is performed at the latter half of the entire construction process, after the completion of water supply / drainage and gas piping burial, and when the ground around the building is leveled.
[0009]
To shorten the foundation work period and prevent detachment such as mortar finish, the concrete foundation finish is most suitable.
[0010]
[Means for Solving the Problems]
The said subject which concerns on this invention is eliminated by the separator of the following structure.
[0011]
The separator, which has been placed on a solid foundation floor for placing concrete at a predetermined interval, has a short-side central cross section in the long-side direction extending the driving part (3) that receives the initial movement hit. Recycled with a driven-in part characterized by initial movement and withdrawal of the separator from the concrete after the concrete is hardened by a raised part that has an impact force transmission function with an integrally molded product that is raised in a square shape Shape separator.
[0012]
Reusable separator with a single-piece molded part that can be struck with a hand hammer after the concrete has hardened to its design strength to cure solid foundations and prevent cracking.
[0013]
Due to the raised part with impact force transmission function, the driven part (3) that receives the impact for the initial movement, the part that fixes the formwork (4), and the part that determines the thickness of the concrete (2) are linked together, ready-mixed concrete The initial movement of the hammering work such as a hand hammer is possible when it is cured to the design standard strength after 4 weeks.
[0014]
The part (2), which determines the thickness of the concrete, is a reusable separator with a drive-in part whose cavity serves as a drain for rainwater on the foundation floor.
[0015]
In addition, the reusable separator with the driven-in part can be reused to recover the part that determines the thickness of the mold fixing part and the concrete after the concrete has hardened.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a reusable separator with a driving portion according to the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing a usage form of a reuse type separator with a driving portion before attaching a mold to a portion 4 for fixing a pair of molds.
[0017]
Since the reusable separator with a drive-in part in this embodiment is intended for reuse, the short-side central cross section in all of the long-side direction in which the drive-in part (3) receiving the impact for initial movement is extended in FIG. However, the separator body is released from the concrete that has been hardened to the design standard strength by the raised part that has an impact force transmission function. As the material, it is easy to attach and detach the component 1 to be removed, and a synthetic resin molded product and a lightweight alloy molded product that are light in weight and have a strong driving portion 3 that receives the impact for initial movement are suitable materials.
[0018]
Although the existing separator in FIG. 3 was an inverted U-shaped iron plate folded product, the bottom of this basic drain separator is smoothed so that no latency is accumulated.
[0019]
There are raised portion of the impact force transfer function in the integral molding of all the short side middle section of the long-side direction that extends the implantation portion 3 for receiving the initial moving blow has raised shaped B in FIG.
[0020]
In Fig. 5, the part 2 that defines the thickness of the concrete by stopping the formwork is sloped at the top so that it can be pulled out easily.
[0021]
【The invention's effect】
As described above, the reusable separator with a driving portion according to the present invention has the following effects.
[0022]
The holes where the reusable separator with the driving portion was located at an interval of about 60CM became the rainwater drainage on the basement under construction. The rainwater drainage port can save a great deal of time and money for pumping rainwater until the end of the outer wall during construction.
[0023]
In addition, the concrete hole from which the reusable separator with a driving portion is pulled out is filled with a waterproof mortar on the inside, and a waterproof resin such as silicone is filled on the outside, thereby eliminating underfloor flooding from the flower bed after moving in.
[0024]
Furthermore, by pulling out the separator, it is possible to finish the outer periphery of the foundation with concrete, and mortar finishing is not required.
[0025]
And, the concrete finish with the foundation outer part exposed will lead to the early dismantling of the outer scaffold and lead to a shortened construction period.
[0026]
