との接触面積を大きくし、結合を確実にする。(Operation) The above means operates as follows. The PC board 1 for cantilevered slabs becomes the slab formwork as it is during slab construction. The anchor bars 5 and the fixing bars 6 aim to firmly anchor the cast-in-place concrete placed on the floor plate 1 and the floor plate. Further, the caulking groove step 4a increases the contact area between the floorboard 1 and the cast-in-place concrete, thereby ensuring a secure connection.
(実施例)
以下本考案の実施例について図面を参照して説
明する。(Example) Examples of the present invention will be described below with reference to the drawings.
PC板1の床板2は先端部に立上り部3を形成
し、この立上り部の内側に排水溝11を形成する
ための排水溝用段差4bと、コーキング用溝12
を確保するためのコーキング用溝用段差4aとが
階段状に連続して形成されている。 The floorboard 2 of the PC board 1 forms a rising part 3 at the tip, and inside this rising part there is a drain groove step 4b for forming a drainage groove 11, and a caulking groove 12.
The caulking groove steps 4a are continuously formed in a step-like manner to ensure the same.
PC板1内部には立上り部3からコーキング用

架されている。 One end of an anchor bar 5 is buried inside the PC board 1 from the rising part 3 to the caulking groove step 4a, and the other end of the anchor bar protrudes from the side surface of the step 4a, and its extension 5a crosses the step. It is suspended horizontally above the floor plate 2 in a cantilevered state as a fixed end.
床板2上には定着筋6の突出部が長手方向に列
設してあり、同様の定着筋が床板の幅方向に所定
間隔を置いて配筋してある。 Projecting portions of anchoring bars 6 are arranged in rows in the longitudinal direction on the floorboard 2, and similar anchoring bars are arranged at predetermined intervals in the width direction of the floorboard.

After placing the cast-in-place slab reinforcements 8 above,
Concrete is placed so that the terminal end (left end) of the slab top 9 is located above the step 4a, leaving room for creating caulking grooves and drainage grooves 11. Finally, caulking 10 is applied to the caulking groove 12 at the boundary between the terminal end of the slab top 9 and the step 4a, and then mortar is spread over the steps 4a and 4b to form a drain groove 11.

Contributing to the improvement of slab construction, anchor reinforcements and fixing reinforcements integrate the PC board and cast-in-place concrete to strengthen the anchorage between them, and by providing multiple steps, the connection between the PC board and cast-in-place concrete is strengthened. It is possible to provide a high-quality cantilevered slab that does not have defects due to skin separation at the boundary.
