ると、小口塞ぎ板が必要となるばかりでなく、
PC床版の高さ分だけ下階のPC壁の天端のレベル
を下げなければならず、接合部分におけるコンク
リート量が多くなる問題があつた。 Conventionally, the edge of a groove-shaped PC floor slab was placed on the top of the PC wall, the edge of this PC floor was closed with an edge closing plate, and a convex kotsuta was installed on the opposing surfaces of the upper and lower PC walls. There is a structure in which loop anchor bars are integrated with cast-in-place concrete to connect a PC wall and a PC floor slab (Utility Model Publication No. 57-96312). This type of structure not only requires an edge closing plate, but also
The level of the top of the PC wall on the lower floor had to be lowered by the height of the PC floor slab, which caused the problem of an increased amount of concrete at the joint.
本発明の目的は小口塞ぎ板が不要であつて、
PC壁の天端のレベルを上げて接合部分における
コンクリート量を減ずることができるPC壁とPC
床版との接合構造を提供することにある。 The object of the present invention is to eliminate the need for an edge closing plate,
PC wall and PC that can raise the level of the top of the PC wall and reduce the amount of concrete at the joint area
The purpose is to provide a joint structure with the floor slab.

谷部の底部と一致するレベルである。 The present invention provides a joining recess at the top end of the PC wall on the lower floor, a kotsuta at the lower end of the PC wall on the upper floor, a joining bar protruding from the top end and the lower end, and the upper end of the PC wall on the lower floor. A supporting protrusion is provided on the side surface of the wall to support the groove-shaped PC floor slab. And on the support protrusion,
The inner surface of the end of the groove provided in the longitudinal direction of the PC floor slab is placed. The PC wall and PC floor slab are then integrated using cast-in-place concrete.
If the level of the upper end of the supporting protrusion is the same as or lower than the level of the top of the wall on the lower floor, the wall can close the edge of the PC floor slab, but if it exceeds the level of the top of the wall. In this case, the shape of the supporting protrusion needs to be such that the mouth can be sealed. The maximum level of the upper end of the support protrusion when it exceeds the level of the top of the wall is as follows. In other words, the level of the top of the PC floor slab when it is supported by the support protrusion matches the bottom of the valley of the PC floor slab if it were placed on the top of the PC wall. level.

A joint recess 1a is formed at the top, and the upper floor
A kotsuta 2a is protruding from the lower end of the PC wall. Each joining recess 1a faces the valley between the joints 2a. Loop anchor reinforcements 3 and 4, which are connection reinforcements, respectively protrude from the valley between the joining recess 1a and the joint 2a, and the opposing loop anchor reinforcements are arranged in an overlapping state. 6c is the valley of the PC floor slab 6.

It matches the level of the top. This support protrusion is
The groove-shaped PC floor slabs 6, 6 are placed and supported on the upper surface thereof. The PC floor slabs 6, 6 have an M-shaped cross section with two continuous grooves 6a, 6b in the longitudinal direction, and the outer shape of the support protrusion follows the inner surface shape of the groove. The upper surfaces of the end inner surfaces of the grooves 6a and 6b of the PC floor slabs 6 and 6 are placed on the upper surfaces of the support protrusions 5 and 5 to support the PC floor slab.

The shape is not limited to the above example, and includes, for example, a V-shape, a square shape, and the like. Also PC floor slab 6
The upper inner surface of the groove 6a is PC as shown in FIG.
If the support protrusion 5 is at the same level as or lower than the top of the wall 1, the outer shape of the support protrusion 5 does not need to match the inner shape of the groove. Further, the joint reinforcement is not limited to the loop anchor reinforcement, but may be a stretched wall reinforcement, and as a connection method, reinforcing bars may be connected using a joint.
