In the drawings, reference numeral 1 denotes a PCa outer wall plate, and a convex portion 1a is integrally provided on the back surface thereof. Although 1'is also a PCa outer wall plate, this is already integrated with a PCa beam or a PCa column, and it is a PCa outer wall plate with a window sash consisting of a PCa outer wall plate 1 and a continuous window type window sash (P
The outer wall plate unit (Ca) is temporarily mounted on the waist wall. 2 is an upper frame of the window sash, 3 is a lower frame of the window sash, 4 is a cuboid arranged between the upper frame 2 and the lower frame 3, and the cuboid 4 is
As shown in FIG. 5, a plurality of ribs are made of an aluminum material having a rectangular cross section formed on the inner wall surface.

Reference numerals 5a and 5b are round head bolts, and 6a and 6b are nuts to be screwed with the bolts 5a and 5b. These nuts 6a and 6b are embedded in the upper and lower ends of the upright 4. That is, the projecting lengths of the bolts 5a and 5b from the vertical ends are freely adjustable, and are used for adjusting the position of the PCa outer wall plate unit as described later. 7 is a reinforcing member having an L-shaped cross section.
The Ca outer wall plate 1 and the upright 4 are attached, and the lower end thereof is further attached to the waist wall 1 '. The use state of the reinforcement member 7 is as shown in FIGS. 4 and 5, and the bolts 8a and 8b are used to connect the PCa outer wall plate 1 and the reinforcement member 7, and the connection between the upright 4 and the reinforcement member 7. Bolts 9a, 9b are used for connecting the waist wall 1'and the reinforcing member 7 with bolts 10. These various bolts are screwed with nuts (not shown) arranged on the mating member. .

Reference numeral 11 is a push-pull bolt, and the push-pull bolt 11
Has one end screwed into a nut embedded in the convex portion 1a, and
The other end is connected to a mounting member 12 having an L-shaped cross section, a part of which is embedded in a PCa beam. Reference numeral 13 denotes a sliding fastener, which together with the push-pull bolt 11 is used for attaching the PCa outer wall plate 1 to the PCa beam as shown in FIG.
The position of the PCa outer wall plate 1 is adjusted by the sliding fastener 13.

Reference numeral 14 is a PCa pillar, 15 is a PCa beam, 16 is a window glass, and 17 is cast concrete. Next, a method of mounting the PCa outer wall plate with the window sash will be described. Even in the construction method of this embodiment, a window sash is joined to the lower portion of the PCa outer wall plate 1 to form a PCa outer wall plate unit,
The steps up to hoisting the PCa outer wall plate unit by a crane (not shown) are performed in the same manner as in the past.

The PCa outer wall plate unit thus hung up is placed on the waist wall 1 ', as shown in FIG. Here, FIG.
The state where the PCa outer wall plate unit is supported by the upright 4 is shown in FIG. As can be seen from FIG. 3, since the PCa outer wall plate unit is supported via the bolts 5a and 5b,
An excessive force does not act on the upper frame 2 and the lower frame 3 of the window sash, and the upper frame 2 and the lower frame 3 of the window sash are less likely to be damaged. The protruding length of the bolts 5a and 5b is PCa.
When the outer wall plate unit is placed on the waist wall 1 ', the PCa outer wall plate unit is appropriately positioned and adjusted.

Furthermore, in order to prevent the PCa outer wall plate unit temporarily mounted on the waist wall 1'from collapsing in the front-rear, left-right direction, as shown in FIGS.
a Attach to outer wall plate 1, upright 4 and waist wall 1 '. continue,
As shown in FIG. 6, the convex portion 1a of the PCa outer wall plate 1 and the unfinished PCa beam 15 on the upper floor are connected using a push-pull bolt 11, and the sliding fastener 13 is attached as shown in FIG. , The position of the PCa outer wall plate 1 is adjusted.

After the mounting position of the PCa outer wall plate unit is determined, concrete is poured to the height shown by the phantom line in FIG. 7 to form the floor surface of the upper floor, and the PCa outer wall plate 1 is fixed. . After curing the cast concrete, the bolts 5a and 5b are loosened to release the force against the load exerted by the PCa outer wall plate unit, and the reinforcing member 7 is also removed.

The installation work on the upper floor is also carried out by repeating the above steps. As described above, according to the construction method of this embodiment, since the PCa outer wall plate with the window sash can be reliably supported by the load receiving bolts built in the upright of the window sash, no erection stand or the like is required at all, and it is simple and The PCa outer wall plate unit can be safely supported in a temporarily fixed state. That is, PCa is made by the upright window sash.
Since the outer wall plate unit can be supported, the stability is high and the risk of an accident is extremely low as compared with the case where the erection table is used.

Moreover, with the PCa outer wall plate temporarily mounted on the waist wall, the PCa is fixed by the bolts built in the upright of the window sash.
Since the mounting position of the outer wall plate can be easily adjusted, workability is excellent, and a small reinforcing member having a simple structure can be used, so that the cost is low.

[0020]

According to the present invention, when installing a PCa outer wall plate to which a window sash is attached in advance to the frame of a building, the work safety is high, and the mounting position of the PCa outer wall plate can be easily adjusted. The work of attaching the outer wall plate can be performed efficiently.
