DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of attaching a PC outer wall plate having a window sash to a PC outer wall plate attached to a building frame.

[0002]

2. Description of the Related Art Conventionally, when mounting an outer wall of a building composed of a window sash and a PC board to a building frame, the PC outer wall board is lifted and guided using a crane or the like, and is sequentially mounted and fixed at a predetermined position of the building frame. The work of suspending the window sash and fitting the glass was performed in a separate process.

[0003]

However, of the PC outer wall boards to be mounted, the P on the window of the waist wall joint is not provided.
Attention was required when attaching the C outer wall plate. That is, a PC with a configuration in which the lower half window sash is attached
In the case of the outer wall plate, it is attached to a fastener mounted on an existing beam by a crane or the like, but at the time of this mounting work, a mounting table for temporarily mounting the PC outer wall plate was necessary. .

In such a mounting method,
Since the PC outer wall plate, the window sash, and the glass are separately mounted in three steps, the steps are complicated, and there is a problem that the construction period is significantly increased.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a method of mounting a window sash on a PC outer wall plate and attaching it to a building frame. After suspending the PC outer wall plate on a gantry by a suspending jig and mounting a window sash through a reinforcing jig attached to the PC outer wall plate, the PC outer wall plate with the window sash mounted thereon is removed. This is achieved by a method of attaching a PC outer wall plate having a window sash, which comprises removing the reinforcing jig after attaching to a building frame.

[0006]

As described above, the PC outer wall plate is hung on the gantry by the hanging jig, the window sash is mounted on the PC via the reinforcing jig to be mounted on the PC outer wall plate, and the glass is fitted. By adopting the method of removing the reinforcing jig after attaching the installed integrated PC outer panel to the frame of the building, it is conventionally necessary to provide a mounting base for mounting the PC outer panel to the beam. Instead, a separate process for attaching the window sash can be performed at the ground level, thereby achieving labor savings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for mounting a PC outer wall plate having a window sash according to the present invention will be described below with reference to FIGS. 1 to 5 are explanatory diagrams of the flow of the mounting operation. Hereinafter, each member and jig used in the method of the present invention will be described.

Reference numeral 1 denotes an assembling base, on which a suspending jig 2 is provided. Reference numeral 3 denotes an upper floor and a lower floor PC floorboard attached to the beam H, and another PC outer wallboard 14 is already disposed on the PC floorboard 3. Reference numeral 4 denotes a PC outer wall plate suspended by a bolt V at the lower end of the suspending jig 2, and reference numeral 4a denotes a bolt drilled in the PC outer wall plate 4 and used for temporary connection with the suspending jig 2. The holes 4b are bolt holes for fixing to a building frame, and the bolts 4c are bolt holes used for temporary connection with a reinforcing jig 5 described later.

Reference numeral 5 denotes a reinforcing jig which is temporarily connected to the PC outer wall plate 4 and is used to ground the window sash 6 on the PC outer wall plate 4. 5a is a brace for vertically holding the reinforcing jig 5. Reference numeral 6 denotes a window sash having glass incorporated therein. The lower end of the PC outer wall plate 4 and the existing P
It is attached to the upper end of the C outer wall plate 14 by a mounting bracket K, respectively.

Reference numeral 7 denotes a bracket used for temporarily connecting the window sash 6 to the reinforcing jig 5. Hereinafter, the mounting operation of the PC outer wall plate using the method of the present invention based on the above configuration will be described with reference to FIGS. The hanging jig 2 provided on the assembly base 1 is connected to the bolt hole 4a of the PC outer wall plate 4 with a bolt V.
(Refer to FIG. 1) The reinforcing jig 5 is temporarily connected to the bolt hole 4c of the PC outer wall plate 4 with a bolt V. Further, a brace 5a is attached along the reinforcing jig 5 in order to keep the reinforcing jig 5 vertical.
(See FIG. 2) Then, the upper end of the window sash 6 is fixed by the mounting bracket K below the PC outer wall plate 4, and the lower end is temporarily connected to the reinforcing jig 5 via the mounting bracket K and the bracket 7, thereby completing the ground work. .

(Refer to FIG. 3) Guide the PC outer wall plate 4 to the predetermined position,
The PC outer wall plate 4 is fixed to the upper floor plate 3 with bolts V in a stable state using the camber C or the like. Next, the bracket 7 connecting the lower end of the window sash 6 and the reinforcing jig 5 is removed, and the lower end of the window sash 6 and the existing PC outer wall plate 14 are fixed to the lower floor plate 13 by the mounting bracket K. Thus, the PC outer wall plate 4 is attached to the building frame. Then, the suspending jig 2 and the reinforcing jig 5 holding the upper end of the PC outer wall plate 4 are removed from the PC outer wall plate 4 to complete the operation. (Refer to FIG. 5) As described above, the distortion of the screwed portion caused by the inevitable vibration when the PC outer wall plate 4 screwed so as to suspend the window sash 6 at the lower end to the predetermined position is conventionally used. By using the reinforcing jig 5 according to the present invention, the mounting can be performed while maintaining the set accuracy without being generated.

[0011]

According to the present invention, a method for mounting a PC outer wall panel having a window sash according to the present invention is a method for mounting a PC outer wall panel having a window sash to a building frame. The PC outer wall panel is suspended on a gantry by a suspending jig. After mounting the window frame on the reinforcing jig temporarily fixed to the PC outer wall plate, installing the PC frame wall plate with the window frame mounted on the building frame, and then removing the reinforcing jig. This is a characteristic construction method. According to this method, the PC outer wall plate on which the window frame is grounded via the reinforcing jig is attached to the building frame, and then the reinforcing jig is removed. The work can be performed in a safe place and smoothly.
