【考案の詳細な説明】
本考案は、天井型枠などの脱型に利用できる天
井などのインサートに関するものである。[Detailed Description of the Invention] The present invention relates to an insert for a ceiling, etc., which can be used for demolding a ceiling formwork, etc.
従来より、例えば天井型枠を脱型する場合、天
井型枠はバールでこじつて脱型するのであるが、
梁や壁などに囲まれた比較的面積の小さい部分に
おける隅は、バールなどが差込みにくく脱型作業
が面倒であつた。 Traditionally, for example, when demolding ceiling formwork, the ceiling formwork is removed by prying it with a crowbar.
It was difficult to insert a crowbar into the corner of a relatively small area surrounded by beams or walls, making demolding work troublesome.
本考案の目的は、インサートを用いて天井など

ｂに収納可能である。 1 and 2, the insert main body 1 is provided with a mounting portion 1a on its outer periphery, and a nail hole 1b passes through this mounting portion in the thickness direction.
A bolt storage hole 2 is provided in the axial center of the insert main body 1, facing upward from the bottom surface. This storage hole 2
The upper side is a female screw part 2a, and the lower side is a flange storage hole part 2b with a tapered cross section.
Furthermore, the opening at the lower end is a washer storage hole 2c having a larger diameter than the storage hole 2b. A bolt 3 is housed in the bolt housing hole 2. As shown in Figures 1 and 3, this bolt has a male threaded part 4 on the upper side, a conical flange part 5 which is a pressing part almost in the center, and a rotary operation part 6 on the lower side. A groove 6a into which the tip of a screwdriver can be inserted, for example, is formed on the end face of the part. The male threaded portion 4 is screwed to the female threaded portion 2a of the insert body, and the flange portion 5 is connected to the storage portion 2.
It can be stored in b.

内に遊嵌している。 Furthermore, when the insert main body 1 is attached to the upper surface (inner surface) of the ceiling formwork K with nails 8, 8, the end of the rotation operation part 7 is inserted into the hole Ka pre-drilled in the formwork.
It fits loosely inside.

に固定する。 Next, installation of the insert will be explained. First, the bolt 3 is stored in the storage hole 2 of the insert body 1 in advance. In this state, first, the hole Ka made at the end of the formwork near the formwork side of the beam H to be constructed.
Place the insert main body 1 on top and position the lower end of the bolt operation part 6 in the hole. Then, attach the mounting part 1a of the insert body 1 to the formwork K using nails 8, 8.
Fixed to.

ルト３はインサート本体１から外れる。 Also, the operation of demolding the formwork K using this insert will be explained. After removing the beam formwork,
As shown in Fig. 1, when a screwdriver is inserted into the hole Ka of the formwork K and the tip of the screwdriver (not shown) is inserted into the groove 6a of the rotation operation part 6 of the bolt 3 and rotated, the male screw 4 is inserted. Female thread part 2 of main body 1
As the flange portion 5 pushes down the formwork K via the washers 7, the formwork K comes out of the nails 8, and the formwork eventually reaches the ceiling of the slab S as shown by the imaginary line. Remove the mold from the surface,
After that, the raised formwork K is removed. At this time, the bolt 3 is removed from the insert body 1.

Although there is an advantage that the rotation operation can be performed smoothly, the flange portion 5 may of course be brought into direct contact with the upper surface of the formwork K without using a washer. The flange portion may be provided all around the outer periphery of the bolt, or may be provided protrudingly at multiple locations on the outer periphery.

り込まない。 As described above, according to the present invention, it is possible to easily and reliably remove the formwork in areas that are difficult to remove by using the bolts of the inserts that have been attached to the formwork in advance during the framing of the formwork. This can improve building construction efficiency. Also, the presence of the bolt prevents concrete from entering the bolt storage hole of the insert body during concrete pouring.
