Abstract

PURPOSE:To enhance the easiness in execution of works by mounting a window frame to a PC exterior wall plate through a reinforcing jig, erecting it and fixing to a building mass, and removing the reinforcing jig. CONSTITUTION:With a bolt V, a PC exterior wall plate 4 is fixed to a hang jig 2 which is hung down at a mount table for ground assembly, and a reinforcing jig 5 is coupled with the wall plate 4 by the bolt V. The top of a window sash 6 is secured to the lower part of the wall plate 4 through a metal fixture K, while the bottom is coupled with the reinforcing jig 5 by the use of the fixture K and a bracket 7. This is erected in a specified place on the building mass and stabilized using a camber C, etc., and the wall plate 4 is secured to the over-floor floor plate 3 with the bolt V. The bracket 7 is removed, and the bottom of the sash 6 is fixed by the fixture K to an existing PC exterior wall plate 14 of the under-floor. The jigs 2, 5 are removed from the exterior wall plate 4. This ensures safety, simplifies the processes, and shortens the construction term.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for mounting a PC outer wall plate having a window sash, which is one of the PC outer wall plates to be mounted on a building frame.

[0002]

2. Description of the Related Art Conventionally, when an outer wall of a structure composed of a window sash and a PC board is attached to a building frame of a building, the PC outer wall board is lifted and guided by a crane or the like, and then sequentially attached and fixed to predetermined positions of the building body. The work of hanging the window sash and fitting the glass was done in a separate process.

[0003]

However, among the PC outer wall plates to be mounted, the P on the window of the waist wall joint is mounted.
C When attaching the outer wall plate, caution was required. That is, a PC with a configuration in which the lower half window sash is mounted
In the case of the outer wall plate, this is attached to a fastener attached to an existing beam by a crane or the like, but at the time of this mounting work, a pedestal for temporarily mounting this PC outer wall plate was required. .

Further, in such a mounting method,
Since the PC outer wall plate, the window sash, and the glass are separately installed in three steps, the steps are complicated and 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 thereof is a method of attaching a window sash to a PC outer wall plate in advance and attaching it to a building frame. That is, the PC outer wall board is hung on a frame by a hanging jig, and after the window sash is mounted and assembled through the reinforcing jig mounted on the PC outer wall board, the PC outer wall board on which the window sash is already mounted is mounted. This is achieved by a method of attaching a PC outer wall plate having a window sash, which is characterized in that the reinforcing jig is removed after the attachment to a building frame.

[0006]

As described above, the PC outer wall board is hung on the frame by the hanging jig, the window sash is mounted through the reinforcing jig mounted on the PC outer wall board, and the glass is fitted into the window sash. By adopting the construction method of removing the reinforcing jig after mounting the already mounted integrated PC outer wall board to the building frame, conventionally, a pedestal for attaching the PC outer wall board to the beam is required. Instead, another process of attaching the window sash can be performed at the ground assembly position, and labor saving can be achieved.

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 views of the flow of the mounting operation. Each member and jig used in the construction method of the present invention will be described below.

Reference numeral 1 is an assembly frame, and a hanging jig 2 is provided below the assembly frame. Reference numeral 3 denotes a PC floor board for upper and lower floors attached to the beam H. The PC floor board 3 is already provided with another PC outer wall board 14. Reference numeral 4 denotes a PC outer wall plate which is hung and suspended from the lower end of the hanging jig 2 by a bolt V, and 4a denotes a bolt which is pierced in the PC outer wall plate 4 and is temporarily connected to the hanging jig 2. Holes 4b are bolt holes for fixing to the body of the building, and 4c are bolt holes used for temporary connection with a reinforcing jig 5 described later.

Reference numeral 5 denotes a reinforcing jig that is temporarily joined to the PC outer wall plate 4 and is used for assembling the window sash 6 on the PC outer wall plate 4. Reference numeral 5a is a brace for vertically holding the reinforcing jig 5. Reference numeral 6 is a window sash in which glass has been incorporated, and 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 is a bracket used when temporarily joining the window sash 6 to the reinforcing jig 5. Hereinafter, the work of attaching the PC outer wall plate using the construction method of the present invention having the above-described configuration will be described with reference to FIGS. 1 to 5. The hanging jig 2 provided on the assembly stand 1 is connected to the bolt hole 4 a of the PC outer wall plate 4 with the bolt V.
(Refer to FIG. 1) The reinforcing jig 5 is temporarily joined 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 hold the reinforcing jig 5 vertically.
(See FIG. 2) Then, the upper end of the window sash 6 is fixed by the mounting bracket K on the lower portion of the PC outer wall plate 4, and the lower end is temporarily coupled to the reinforcing jig 5 via the mounting bracket K and the bracket 7 to complete the assembly. .

(See Fig. 3) Guide the PC outer wall plate 4 that has been assembled to a predetermined position,
Using the camber C or the like, the PC outer wall plate 4 is fixed to the upper floor plate 3 with bolts V in a stable state. (See FIG. 4) 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 13 by the mounting bracket K. As a result, the PC outer wall board 4 is attached to the building frame. Then, the hanging jig 2 and the reinforcing jig 5 that hold the upper end of the PC outer wall plate 4 are removed from the PC outer wall plate 4, and the work is completed. (See FIG. 5) As described above, the distortion of the screwed portion, which has been conventionally caused by the inevitable vibration when the PC outer wall plate 4 screwed to suspend the window sash 6 at the lower end is guided to a predetermined position, By using the reinforcing jig 5 according to the present invention, it is possible to mount the device while maintaining the set accuracy without causing it.

[0011]

[Effect] The method for mounting the PC outer wall plate having the window sash according to the present invention is a method for mounting the PC outer wall plate having the window sash to the frame of the building, and the PC outer wall plate is hung by the hanging jig on the frame. After mounting the window frame to the reinforcing jig temporarily fixed to the PC outer wall plate, attaching the PC outer wall plate with the window frame mounted to the building frame, and then removing the reinforcing jig. This is a characteristic construction method. According to this construction method, after the PC outer wall board having the window frame grounded through the reinforcing jig is attached to the frame of the building, the reinforcing jig is removed, so that the window frame grounds to the PC outer wall board. The work can be performed smoothly in a safe place.
