[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a PC formwork wall for construction of a building wall in a nuclear power plant or the like.

[0002]

2. Description of the Related Art In a conventional PC formwork method for construction of a building wall structure such as a nuclear power plant, a PC form made of precast concrete is used as a formwork as shown in the front view of FIG. 3 and the perspective view of FIG. I am using frame 1,
At a predetermined position of the PC form 1, an embedded hardware 3 having a stud 2 set up on the back side is embedded in advance in order to support various devices such as piping.

The PC formwork 1 is installed on the outside of the wall reinforcement by the vertical reinforcements 4 and the horizontal reinforcements 5, which have already been constructed. The PC formwork is made by placing concrete on the wall reinforcement on the back side. Build a building wall structure that is integrated with 1.

A plurality of PC molds 1 are connected to each other at their joints via a sealing rubber 6 and level adjusting bolts 7 by connecting metal fittings 8 to seal the cast concrete at the joints and PC. The positions of the molds 1 are adjusted and arranged.

[0005]

In the work of installing the wall formwork by the PC formwork 1, when the PC formwork 1 is installed at a predetermined position, the embedded metal article 3 previously attached to the PC formwork 1 is installed. There is a case where the position of the wall reinforcement due to the vertical reinforcement 4 and the horizontal reinforcement 5 interferes with the stud 2 of No. 4, and at this time, the position of the wall reinforcement is avoided from the stud 2 of the embedded hardware 3 each time. I was working on it.

Therefore, in the construction work of the wall skeleton using the conventional PC formwork 1, there is a problem that the work efficiency of installing the wall formwork is low. The object of the present invention is to provide a PC
By arranging the embedded hardware and the wall reinforcement in the formwork in advance and making it into a unit, interference between the embedded hardware and the wall reinforcement is eliminated, and a PC mold wall that improves the work efficiency of wall formwork installation. To provide.

[0007]

In order to achieve the above object, the PC formwork wall according to the invention of claim 1 is such that the formwork used for concrete pouring in the building wall frame is an embedded metal fitting in the PC formwork. It is characterized by a wall reinforcement that avoids the studs of this embedded metal fitting to form a unit.

According to a second aspect of the present invention, there is provided a PC formwork wall,
It is characterized in that the PC form wall is provided with fixing plates on both sides of which the PC form frames are fixed with lateral reinforcement of wall reinforcement. According to a third aspect of the present invention, there is provided a PC form wall, in which a plurality of arrangements of the PC form walls connect adjacent fixing plates with a connecting fitting.

According to a fourth aspect of the present invention, there is provided a PC formwork wall,
It is characterized in that a receiver for connecting the longitudinal reinforcements is provided above the longitudinal reinforcements which are wall reinforcements. A PC formwork wall according to a fifth aspect of the present invention is characterized in that after the PC formwork wall is installed, concrete is placed on the wall reinforcements to construct a building wall structure.

[0010]

According to the first aspect of the present invention, the PC formwork is pre-embedded with the embedding metal fittings, and the studs of the embedding metal fittings are avoided so that the longitudinal and horizontal reinforcements of the wall reinforcements are provided. Since it is unitized as a unit, there is no interference between the studs of the embedded metal fittings and the wall reinforcement when installing the formwork.

According to the second aspect of the present invention, the horizontal reinforcing bars are fixed by fixing plates installed on both sides of the PC formwork. In the invention according to claim 3, the arranged PC form walls are fixed to each other by connecting the fixing plates adjacent to each other on the left and right sides with the connecting fittings.

According to a fourth aspect of the present invention, the vertical reinforcement of the upper PC form wall is connected to the receiving member provided at the upper end of the vertical reinforcement of the lower PC form wall, and the upper and lower PC form walls are connected. Array. According to the fifth aspect of the present invention, the building wall structure integrated with the PC form wall is constructed by placing concrete on the wall reinforcement in the form installed by arranging the PC form walls.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. As shown in the perspective view of FIG. 1 and the back view of FIG. 2, the PC form wall 9 has the embedded metal fitting 3 embedded in a predetermined position of the PC mold 1, and the stud of the embedded metal fitting 3 is previously formed on the back side thereof. The vertical reinforcing bars 4 and the horizontal reinforcing bars 5, which are wall reinforcing bars, are assembled in a lattice form at a position where they do not interfere with 2.

Both ends of the horizontal bar 5 are provided by welding to fixing plates 10 fixed to both side surfaces of the PC form frame wall 9, and the upper end of the vertical bar 4 is a PC type installed above. A receiver 11 is provided which is connected to the vertical bars 4 of the frame wall 9. The vertical bar 4 is connected to the horizontal bar 5 at its intersection.

Further, a sealing rubber 6 is provided on one side surface and a bottom surface of the PC mold wall 9, and a bolt for adjusting the level of the PC mold wall 9 set above is provided on the upper surface. 7 is provided and configured.

Next, the operation of the above configuration will be described. When constructing a building wall structure, a plurality of PC formwork walls 9 are arranged in order to form a formwork of a predetermined shape prior to placing concrete.

The vertical arrangement of these is adjusted by the bolts 7 provided on the upper surface of the PC form wall 9, and the lower end of the vertical bar 4 is arranged vertically on the lower PC form wall 9. 4 is inserted into the receiving member 11 and connected to each other, and the PC mold wall 9 is closely adhered by the sealing rubber 6 on the bottom surface.

On the left and right sides of the arranged PC mold walls 9, through the rubber for sealing 6 arranged on one side,
Adjacent fixing plates 10 are connected by connecting fittings 12. By connecting the fixing plates 10 of the PC form wall 9 to each other, the lateral reinforcements 5 are also connected to each other, and are closely attached by the rubber 6 for sealing.

The building wall structure is constructed, for example, by assembling the molds with the PC mold walls 9 back to back and then placing concrete in the wall reinforcement. The cast concrete that is about to flow into the gap between the two is sealed by the sealing rubber 6.

Once the cast concrete is cured,
The building wall structure integrated with the PC form wall 9 is completed. Note that P
Studs 2 and longitudinal bars 4 of embedded hardware 3 in C-frame wall 9
And the interference with the horizontal bar 5, in each PC formwork wall 9,
It does not occur because it was constructed by avoiding it during manufacturing.

[0021]

As described above, according to the present invention, since the PC formwork and the embedded metal product are unitized together with the wall reinforcement, the interference between the stud of the embedded hardware and the wall reinforcement can be avoided, and the PC formwork wall. It is possible to construct a wall structure integrated with the above with good work efficiency. In addition, since the PC formwork wall is unitized, there is also an effect that the work process on site can be shortened.
