Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for installing precast concrete wall plates (hereinafter referred to as PC wall plates) between two pillar steel frames built at predetermined intervals in a building using the PC construction method. ) are arranged flush over multiple floors, two on each floor, and these PC wall panels and PC wall panels and column steel frames are integrally connected. The purpose is to create a 1'0 wall slab with the same structure that is durable, easy to manage on-site, and easy to construct. The objective is to make it possible to construct walls that are durable and economical.

In order to prevent sudden destruction of the building's F floor during an earthquake, continuous diagonal walls from the foundation to a specified floor are constructed using cast-in-place concrete. T

In Fig. 1, b... is the column iron base, and C... is the beam main reinforcement.

In applying this idea to a continuous shear wall made of PC walls, the present invention devises the arrangement of diagonal members for bracing built into each PC wall plate, thereby creating a patterned structure. Using PC wall panels that have substantially the same structure, it is not possible to construct an effective brace with a group of PC wall panels, but the overall structure is an inverted V that is prone to bending and breaking.
It is designed to obtain a letter-shaped brace configuration, and consists of a water moka transmission material located along the upper edge of the wall board, and multiple mutually parallel reinforcements that are inclined with respect to this horizontal force transmission material. The diagonal members are provided in a positional relationship such that the lower end portions of the diagonal members adjacent to each other and the lower end portions of the diagonal members are located on the same vertical line; There are multiple lli! vcv or
In addition, two PCs are placed flush on each floor, and the PC
By connecting the C walls and the steel frames of the PC wall plates and columns through the horizontal force transmitting material and the diagonal material for forming the braces, a continuous seismic structure with inverted V-shaped braces is constructed. It is characterized by a structure with a wall.

According to this configuration, the following advantages can be obtained.

That is, I
Multi-layer resistance using cast-in-place concrete that strengthens the gf resistance and brings the failure mode closer to the bending failure type; a wall is made of PC
The VC structure is simply divided into each floor, and each floor is divided into two PC wall panels, diagonal members for brace construction, and diagonal reinforcing bars for the upper layer. It is built into a layout format divided according to the PC4 version, and
By placing these PC wall plates and columns between the steel frames, the PC wall plates and columns (and the steel frames can also be integrated into one piece).
□・ It is possible that in the case of a temple, the arrangement form of the diagonal members for ffJ* structure stored inside the PC wall board may be different from the PC on each floor.
The PC wall plate structure becomes random.

Therefore, it is necessary to manufacture many types of PC wall panels.
PC wall board production performance is poor, material management on site is troublesome, and there are restrictions on the compliance of PC wall board that is inserted between pillar steel frames, so construction workability is Not only is the production cost of slag high, but the overall cost is quite high.

As mentioned above, in this Hakumei, each P (3 wall slabs) is equipped with a horizontal force transmitting material, a plurality of diagonal members for constructing braces parallel to each other and marked with #+ to this horizontal force transmitting material. Inside R6f'L1 These diagonal members are installed in a positional relationship such that the lower end of the slope and the lower end of the slope of adjacent diagonal members are located on the same vertical line, so the individual PC wall panels Although this is not an effective bracing configuration, the overall structure of the frame is in an inverted V-shape, that is, the shear strength is reinforced to prevent bending failure.
JI mode braces can be obtained, and since all P (3 wall slabs) have virtually the same structure, productivity is high, material management is easy, and there are no constraints on the order of /T4. There are no problems, and the workability is good.

Therefore, a multi-layer corrosion-resistant wall that precedes bending failure can be constructed easily and adjacently.

μF1 An embodiment of the present invention will be described based on FIG. 2 and subsequent drawings.

Figure 2 shows the entire structure of a multi-layer shear wall for a building using the tx-pc construction method, and Figure 4 shows its main parts. As shown in Fig. 2, the PC wall board has a horizontal force transmitting material 2 located along the upper edge of the wall board, and a plurality of mutually parallel striations that are inclined with respect to the horizontal force transmitting material 2. The diagonal members 8 for construction are built-in, and the diagonal members for the brace construction that are connected to these diagonal members 8 are not internalized at all. In addition, the diagonal members 3... are phase! Diagonal members 8... are provided in such a positional relationship that the diagonal 'F end and the inclined lower end of each diagonal member 8 are located on the same vertical line.
