て型枠とその工法が要望されている現状にある。The plywood of wood which is widely used as a formwork at present is the above-mentioned (a), (c), (d).
Is excellent, but the finished concrete surface needs to be repaired and reuse is limited to a part. Moreover, recently, the disposal of industrial waste is gradually becoming difficult and the processing cost is soaring. In addition, the disposable formwork is regarded as a problem from the viewpoint of protecting wood resources. On the other hand, as other mold materials, an iron plate or the like is used in part, but the iron plate is excellent in (b) and (e), but (a), (c), and (d) There's a problem. Further, the wood wool cement board is good in the above (a) and (d), but is not good in other points. In addition, as a so-called discarded form that is not removed after use as a form, PC boards and metal plates with tiles and stones attached to the surface, fiber reinforced concrete, etc. are used in some cases, and in this case the finished surface is well However, there is a problem that the formwork is disassembled and discarded, but there are problems such as heavy weight, being unable to be processed, and having almost no air permeability, so that its use is limited. Furthermore, whichever formwork is used, a supporting member for holding this formwork is required, and generally steel pipes are often used, but it is difficult to handle long steel pipes depending on the construction site, or noise during handling. Is often a problem, and therefore, there is a demand for a discarding formwork and a construction method thereof which are excellent in each of the above conditions.

水率とはALC研究会報告書の吸水係数(一面吸水)の
試験方法による48時間値である。The ALC plate used in the present invention has a thickness of less than 75 mm, preferably 50 mm or less, a one-sided water absorption rate of 5% or less, preferably 2% or less, and further, the reinforcing bars are welded in which the horizontal bars are bent in a corrugated manner. It is desirable to process the one in which the gold steel is buried into a desired size before use. The one-sided water absorption rate is a 48-hour value according to the water absorption coefficient (one-sided water absorption) test method of the ALC Research Group report.

れば、前記のような問題は発生せず絶縁体を貼着する必
要がない。The reason is that a normal ALC panel having a thickness of 75 mm or more and a water absorption on one surface of 10% or more is used.
When concrete is poured directly on the panel surface, depending on the amount of concrete, the panel may absorb water from the concrete contact surface, adversely affecting the hardening of the concrete, and shrinking when hardening the concrete may cause cracks in the ALC panel. This is because it is necessary to attach an appropriate insulator to the inner surface of the ALC panel. On the other hand, the thickness is less than 75 mm, preferably 50 mm to 35 mm,
Furthermore, if the water absorption on one surface is 5% or less, preferably 2% or less, the above problems do not occur and it is not necessary to attach an insulator.

The number of supporting devices can be reduced.

By using the board as a waste formwork for the inside and outside walls of buildings, foundations, pillars, beams, and floors, it does not adversely affect the hardening of concrete without adhering an insulator to the inner surface, and it has moisture permeability. Therefore, the excess water of the poured concrete can be evaporated. After the concrete is placed, it can be used as the outer surface as it is in close contact with the concrete, so the dismantling of the formwork, carrying out, repair of the finishing surface, etc. are simplified, the construction period can be shortened, and the surface of the ALC plate is precut Alternatively, if a painted design panel is used for the outer wall, it is possible to have an excellent design appearance. Furthermore, if it is used indoors, it becomes a wall surface with excellent heat insulation and sound absorption properties, and since the interior material can be attached to the surface, finishing is easy.

む利点がある。Further, as described above, when the water absorption on one surface of the ALC plate is 2% or less, the water absorption of the concrete is small and the scattered concrete does not adhere to the panel, so that the finished appearance is good. Also, even if the thickness is as thin as 50 to 35 mm, if a reinforcing reinforcing bar having a welded wire mesh with lateral corrugations bent in a corrugated manner is used, there is less risk of damage during handling, and the number of supporting tools attached is also small. It has the advantage of being small.

A pad for supporting the surface of the ALC plate, which is attached to the separator penetrating the other ALC plate for wall surface or the frame which is erected at a desired interval in opposition to the LC plate,
The tip of the separator that does not protrude from the LC plate surface is screwed to the back surface, and the front surface is made up of a jig that can be screwed with a pad. If the formwork is assembled with this support tool, it can be attached at any position. It is possible, sufficient strength is maintained without using a supporting member such as a steel pipe, it can be easily attached and detached, and the finished appearance is good because the separator is not exposed on the surface of the ALC plate.

上げが容易となる。As described above, according to the present invention, the thickness 7
ALC boards of less than 5 mm are used for building interior and exterior walls, foundations, pillars,
Since it is used as a discarding form for beams and floors, concrete can be smoothly hardened without attaching an insulator to the inner surface, and since it has moisture permeability, excess water of poured concrete can be evaporated. In addition, after placing concrete, it can be used as the outer surface as it is in close contact with the concrete, so the dismantling of the formwork, carrying out, repairing the finishing surface, etc. can be simplified and the construction period can be shortened. Or, since a painted design panel can be used for the outer wall, it can have an excellent appearance. Furthermore, when it is used indoors, the wall surface has excellent heat insulating properties and sound absorption properties, and an interior material can be attached to the surface of the wall surface, which facilitates finishing.
