FIG. 1 shows a construction state of this example, and FIG. 2 shows a gate-shaped PC column and beam. The PC column beam body 1 is integrally formed by arranging a half-split column part 2 that vertically divides the column on both sides and interposing a horizontal beam part 3 at its upper end. Each half split pillar part 2
A splice sleeve 21 into which a connecting rebar can be inserted is buried at the lower end thereof, and is opened at the lower end, and a connecting rebar 22 inserted above the splice sleeve 21 is projected upward from the upper end.

Further, each half-split column 2 is provided with an insertion hole 23 extending in the direction along the beam 3, and a sheacotter recess 27 is formed in the mating end face of the half-split column 2. further,
At the upper end of the beam 3, a reinforcing bar 31 is projected. The half column portion 2 and the beam portion 3 are arranged in a formwork, reinforced with concrete, and integrally produced in a factory.

In this example, as shown in FIG. 1 and FIG. 3, the rebars 2 for connection, which suspend the PC column beam 1 and project from the floor 4, are provided.
2 are inserted into the splice sleeve 21 at the lower end of the half column 2, and each PC column 1
Are continuously installed on the floor 4. Then, as shown in FIG. 3, the PC steel rod 24 is inserted into the communicating insertion hole 23 and fixed by the nut 25, and the mortar sealing 26 is applied to the mating surface of the half-divided column portion 2 having the sheer cotter recess 27 to form the pillar. 20 is formed. The mating surface of the half column 2 is about 1 to 2 cm.

The pillar 20 thus formed is strongly friction-bonded to the joint surface by the compressive force applied to the PC steel rod 24 to ensure the integration, and the sheer cotter recess 27 is formed.
Mortar sealing 2 on the mating surface of the half column 2
By doing this, it is firmly formed. Further, the beams are directly arranged between the columns by the beam portions 3.

Then, as shown in FIG. 1, the PC wall plate 5 is installed on the floor by inserting the connecting rebar 42 projecting from the floor 4 into the splice sleeve 51 embedded at the lower end thereof, and connecting it to the pillar 20. Set up. Then, the PC floorboard 6 is placed on the upper ends of the pillar 20, the beam portion 3 and the PC wall board 5, and the upper reinforcing bar 7 connected to the reinforcing bar 31 for reinforcing bars of the beam section 3 of the PC column beam body 1 is placed thereon. Then, concrete is cast on them to form the floor 4.

As a result, the concrete is placed at the base of the pillar 20, so that the pillar 20 is further fixed, and the reinforcing bar 22 for connecting, the reinforcing bar 31 for reinforcing the beam 3 and the PC wall board 5 are arranged on the floor 4.
That is, the connecting reinforcing bar 42 of FIG. Therefore, if the construction is performed in the same manner as described above, the floors on the upper floors are sequentially formed.

As described above, according to this embodiment, the columns 20 are strongly frictionally connected by the compressive force of the PC steel rods 24 by combining the half-split column parts 2, and in particular, the beam parts 3 are integrally connected.
The process of connecting the beams is not required, and the upper reinforcement for forming the floor and concrete driving are simplified. Furthermore, since the beams are integrally formed with the pillars, the mounting positions of fittings such as window sashes and doors are predetermined, so it is possible to calculate the installation of them, or to integrate them into the PC pillar beam body in advance. Since it can be formed, quick and easy construction can be achieved.

Although this example is constructed as described above, the present invention is not limited to this. For example, regardless of the shape of the half column and the beam, the type of the PC steel rod, the number to be attached, and the fastening means are not limited.

As shown in FIG. 4, similarly to the present embodiment, a half columnar portion 2 having a splice sleeve 21 and a connecting rebar 22 is provided.
The horizontal beam portion 30 is integrally formed on the upper end of the
The rebar reinforcing bar 301 may be projected on the open end face of the PC column beam body 10 having the rebar reinforcing bar 302 projecting on the upper end of the beam part 30. As shown in FIG. 5, the open end face of the beam part 30 may be formed. After continuously installing the respective PC column beam bodies 10 in a state of facing each other, the PC steel rods 24 are inserted and fixed in the insertion holes 23 which are communicated with each other, and the mortar sealing 26 is applied to the mating surface of the half-divided column portion 2. The pillars 20 may be formed, the reinforcing bars 301 for reinforcing bars of the beam portions facing each other may be connected to each other, and the concrete 303 may be placed therebetween to form the connected beams. According to this, in addition to the effect of the present example, a long beam can be easily formed because the beam is divided.

Further, the fitting state of the half-split column portion is also appropriate, and by changing the position of the insertion hole of the PC steel rod, it is possible to form a column having a beam portion at a right angle as shown in FIG.

[0017]

According to the first aspect of the present invention, by connecting the combined half-split column portions with the PC steel rod, the columns strongly frictionally coupled by the compressive force are integrally formed, and the beam portions are integrally connected. Therefore, the step of connecting the beams is not required, and the effect of simplifying the upper reinforcement for forming the floor and the concrete driving is great.
In addition, since the beam is a PC column beam integrally formed with the column, the mounting position of a fitting such as a window sash or a door is determined in advance,
There is also a great advantage that easy and quick construction can be achieved because the mounting of them can be performed, or the fittings can be preliminarily incorporated into the PC column and beam and integrally formed. Further, claim 2 is
By connecting the combined half-divided pillars with PC steel rods, the strongly frictionally connected pillars are integrally formed, and the upper bar reinforcement and concrete driving for floor formation are simplified, and the beams are integrally connected. Since the part is divided, a long beam can be easily formed.
