Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a PCC wall pressure plate having a finished surface such as tiles on the outer wall surface.

When the sash has continuous windows and tiles are pasted on the waist and lower walls, those areas often have spandrel-like PCC walls.

However, in this case, as shown in FIGS. 5 and 6, a spandrel-shaped PC board (A) having a finishing material (α) on the outer wall surface and a cast-in-place reinforced concrete girder (C) or a cast-in-place steel reinforced concrete girder (C' ) are separated from each other, and when designing and calculating the concrete cross section of the girder, the 9-rel span 20 plates are not added to the effective thickness of the girder, so the volume of concrete is large, which is uneconomical.

The present invention was proposed to solve this problem, and involves embedding the main beam reinforcement and part of the stirrup reinforcement surrounding the main reinforcement in a vertical slab with a finishing material layered on the outer wall surface. The present invention also relates to a PCC wall pressure plate having a finished surface characterized by the ends of the stirrup bars protruding from the inner surface.

PCC wall pressure according to the present invention As mentioned above, the main beam reinforcement and a part of the stirrup reinforcement surrounding the main reinforcement are embedded in the vertical plate with the finishing material layered on the outer wall surface, and the end of the stirrup reinforcement Since the section is configured as a half beam protruding from the inner surface of the vertical plate, when cast-in-place reinforcing bars or reinforced steel concrete girders are cast in contact with the inner surface of the PCC wall, the stirrups are placed inside the girder. The projecting part of the reinforcement is anchored and the girder integrated with the vertical plate is constructed. Therefore, the vertical plate is added to the effective thickness of the concrete cross section of the girder, and the wall plate is added to the spanned nine rails. By using 20 plates of the shape, the concrete volume does not increase and economical design and construction become possible.

Furthermore, since the finishing material is layered on the outer wall surface of the vertical plate in advance, finishing work can be carried out accurately and finishing work on site can be omitted, saving labor and shortening the construction period.

The present invention will be described below with reference to the illustrated embodiments.

(A) is a PC wall board in the shape of a sundrel, vertical version (1)
Finishing materials such as tiles are pre-applied to the exterior walls of buildings in factories.

The main beam reinforcement (
3) and the stirrup muscle (4) surrounding the main muscle (3)
is built-in, and the end of the stirrup strip (4) is a vertical version (
1) It protrudes from the inner surface.

As shown in Figs. 1 and 3, a cast-in-place reinforced concrete girder (B) or a cast-in-place steel reinforced concrete girder ( When B pieces are constructed, the same girder (B
) (B is integrated with the vertical plate (1) through the protruding part of the stirrup bar (4), and the main beam bar (3) and stirrup bar (4) in the same vertical plate (11) remain as they are. Said girder (B) (Constituting a part of the main beam reinforcement and stirrup reinforcement of B-ri.

By integrating the girder (B) (B and the PC wall slab) in this way, the vertical plate (1) is added as the effective thickness of the concrete cross section of the girder (■). This prevents the volume of concrete from collapsing, allowing for economical design and construction.

The girder casting surface of the vertical slab (1) is formed into a rough surface or provided with a bumper to integrate it with the girder placement concrete.

Furthermore, in the above embodiment, the stirrup bars (4) partially buried in the PC wall plate A) are arranged in an open type, but as shown in Fig. 4, the stirrup bars (4) are arranged in a closed type. Good too.

In the drawings, parts equivalent to those of the above embodiment are given the same reference numerals.

Although the present invention has been described above with reference to embodiments, the present invention is, of course, not limited to such embodiments, and can be modified in various designs without departing from the spirit of the present invention. .
