Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to grinding used in the sash tipping method. The sash tipping method has recently been adopted at many construction sites as part of labor-saving efforts, but while it has achieved the objectives of shortening the construction period and saving labor, it has the disadvantage of reducing quality and accuracy by 1.
It's happening.

Conventionally, the formwork used in the sash tip construction method consists of a single formwork for the opening between the inner and outer walls of the building frame, and an opening frame is placed around it. It is difficult to remove and may cause deformation.

In cases such as wooden formwork, it is completely destroyed and removed.
The window limit is V, and even in the case of Kinka Circulation, extensive repairs will be required at the site limit. And, when removing the formwork r, there is a drawback that the concrete IJ is easily damaged, and a great deal of time is consumed in removing the formwork r.

Special request for these! r7-. The invention of No. 397KK, ``Formwork in the sash tipping construction method,'' is [an external formwork with an external formwork r on the inner periphery of the mouth part on the outside side of the opening of a concrete building. The opening frame of the sash prepared for the opening [The concrete wall is divided into the supporting internal formwork, and the external formwork and internal formwork are removable, and the concrete is poured separately into the external darkness and internal formwork. This is the case with the Satsushi construction method, which is fastened so that it can be dismantled after installation. Since the mold is divided into the inner and outer parts of the opening and joined together, the mold can be easily dismantled and the amount of concrete broken can be reduced. In addition, the weight of the straw is reduced, making it easier to handle, and deformation and damage to the formwork during disassembly are reduced. Since the internal formwork and external formwork r are separated at the outside surface of the sash opening frame, the internal formwork can be used regardless of the thickness of the concrete.

And it is possible to use the mounting frame r<jireshi. Furthermore, based on the above-mentioned invention, there have been many inventions and ideas that have made it easier to remove the adhesive by dividing and fastening the concrete formwork at the opening into upper and lower vertical shapes in the direction of projection. being done.

However, in each of the above-mentioned inventions and ideas, the concrete formwork for the opening is first assembled by fastening it to an outer plate that is supported by an external scaffold or the like. However, if this was done, the concrete would have to be brought inside, and it would be difficult to support the molds of the floorboards on the upper floor until after that. The work efficiency is not good because the outside plate of the concrete IJ-toe which is formed on the outside of the building is first erected. Therefore, the conventional method of supporting the opening frame by fastening the concrete crusher to the outside plate is accompanied by restrictions on the process.

However, it is difficult to use the concrete form r of the opening of one conventional row to support it from the indoor side. That is, since it is attached to the outer plate with respect to the outer plate r, it is cantilevered from the outer plate. Even if the outer plate of the formwork that forms the outer wall surface γ of the concrete formwork covers the opening Y, it will not cause any damage even if it is damaged, so it can be attached to the concrete formwork freely. However, since the inner panel on the indoor side is finished with a base material and serves as a concrete IJ-type, the opening cannot be covered or damaged.

Therefore, there is a problem in the sash tipping construction method that it is not possible to fix the concrete grinding surface to the inside of the room, as in the invention proposed by Takinori Ail.

Therefore, even if the form r of the opening can be held accurately and firmly, the opening frame cannot be fitted inside or on the outside, so it is necessary to provide some clearance r in the expected direction for assembly. Therefore, in the conventional example, in order to fix the opening frame r, a fixed foot of the sash opening frame r is provided on a bracket attached to the internal formwork from the inside side, and the sash opening frame r is pressed and fixed to the outside side. In this way, the position of the opening frame will be determined based on the outside reference.If the distance between the outside and inside walls of the concrete wall is not extremely accurate, the opening frame will move in and out from the indoor side.

The present invention is a concavity for openings used in the sash tipping method as a single row! J - To W 伜r The sash r of the formwork supports the internal formwork r so that it can be fixed to the inner board on the indoor side, and extends to the inside side and fits into the edge portion that comes into contact with the open frame r of the inner board. In the case where a fitting part r is provided, and a spraying member r is provided to the inner plate on the outside of the fitting part, an anchor and opening holding member r is further attached to the outer periphery of the opening frame, and the opening frame holding member is fixed to the inner plate. It is something that

Additional external formwork 3! f is an external formwork, which is separated from the external formwork 23 to facilitate demolding.

A stay 37 is arranged inside the external wall frame 3.

One end of the stay 37 abuts against the cross beam and 2/ and can be removed by tightening the bolt and nut 3g. The other end of the stay 370 is an outer plate, 3q' is a flange to be attached, and a reinforcing material is provided between the members on each side of the rectangular formwork section that will become the concrete mold around the outer periphery of the external formwork section 3.

The internal formwork 23 is pulled out to the inside, and the external formwork 23 is pulled out to the outside.Finally, the attached external formwork 3jtf is pulled out. Plug the hole in the inner material where nut/6 was inserted.

In accordance with the above, the present invention relates to a formwork used in the sash tipping method, in which an opening frame r is fitted into the formwork, an opening frame holding member k which also serves as an anchor r is placed in the opening frame outer periphery Q groove, and the opening frame Insulating material r for the interior plate that serves as the base for the interior finishing material and the inner grinding material
Since the opening frame is fastened through the opening frame, the position of the opening frame in the forward direction is T with respect to the inside plate r, so the opening frame is arranged at one foot position when viewed from the indoor side. Attachment member to the inner plate of the wall grinding in the opening formwork? Since it is provided, the grinding installation work can be performed by first standing the inner plate r.

The inside board is supported by the floor of that floor and the formwork is fixed to the inside board, so the inside board side is the reference point.9. The sash opening frame r can be placed at a fixed position in the expected direction. Since the internal formwork fits into the opening of the inner plate, a constant internal formwork can be used in which the opening frame is placed accurately regardless of the wall thickness.

The pressure of poured concrete is firmly supported by fastening the internal formwork to the inner plate and fitting the internal formwork into the opening of the inner plate. The inner periphery of the fitting part of the internal grinding is connected with a cross beam, and the cross beam is connected to the stay fixed to the external formwork, so the formwork divided into the inside and outside is firmly connected, and the Lj) III plate Heavy…
, there is little deformation of the concrete wall due to concrete placement pressure. Since I installed a cross beam R, is it internal Shun V? When inserting it into the inner plate opening, you can hold it by hand to align the position and work safely.
