DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for adjusting a so-called glass image of a curtain wall.

[0002]

2. Description of the Related Art A glass image of a curtain wall is a phenomenon in which a surrounding scene is reflected on a glass group of the curtain wall and is reflected as one picture. In this case, if the faces of the glass group do not coincide with each other in angle, a part of the picture is distorted and the dignity of the building is impressively reduced.

[0003] Therefore, this kind of glass image has been adjusted from the time of construction. In this case, conventionally, in the process of assembling or assembling the glass, a guard from the ground finds a distorted portion of the glass image and communicates with a worker in the room by a transceiver, and the worker in the room adjusts the angle of the glass. And the position in the indoor and outdoor directions was adjusted.

[0004]

However, when buildings are adjacent to each other, the buildings obstruct the field of view, making it difficult to easily find glass-distorted portions from the ground. It is difficult to see the floor. In addition, there is a tendency for communication errors between the ground surveillance staff and the workers in the room.
It takes a lot of trouble.

Accordingly, an object of the present invention is to make it possible to easily adjust a glass image and to increase the adjustment accuracy.

[0006]

The object of the present invention is to emit a laser beam in a room of a building substantially in parallel with the glass to be assembled, and to use the laser beam as a reference line to apply a laser beam perpendicular to the reference line to the outer surface of the glass. The solution is to project on multiple points, measure the reflected laser light at each point, measure the positions of multiple points on the outer surface of the glass, and adjust the surface position of the glass based on the measured position of each point it can.

[0007] Further, as a device, a reference laser beam emitting device that emits a visible reference laser beam substantially in parallel with the glass to be mounted, a measuring cart, and a glass orthogonal to the truck to be assembled from inside a building. A distance measuring device that is mounted with multiple projection directions, projects laser light onto the outer surface of the glass, detects reflected laser light, and measures the distance to the outer surface of the glass, and its surface position while the glass is suspended It is possible to solve the problem by providing a glass position adjusting means capable of adjusting the position and a means for positioning the measuring cart so that the projection directions are orthogonal to each other with reference to a visible reference laser beam.

[0008]

According to the present invention, in a room of a building,
By emitting a laser beam substantially parallel to the glass to be assembled and using this as a reference line, an orthogonal position with respect to the glass can be set. By projecting a laser beam orthogonal to this reference line to multiple points on the glass outer surface, measuring the reflected laser light at each point, and measuring the positions of the multiple points on the glass outer surface,
The angle of the glass can be known, and the position of the glass can be adjusted based on the angle.

As described above, in the present invention, since the laser beam is used, the positioning accuracy is high. Moreover,
Since the work can be performed from the room, the position of each glass can be adjusted quickly and without being affected by the location conditions of the building.

[0010]

Next, the present invention will be described in detail with reference to the embodiments shown in the drawings. 1 is a floor of a certain floor of a building having a curtain wall, and 2 is a glass or panel of the curtain wall. In the present invention, the visible reference laser beam L ₀ is supplied substantially parallel to the glass 2 to be assembled by the reference laser beam emitting device 3.

A plurality of the measuring carts 10 are attached with a projection direction orthogonal to the glass 2, and a laser beam L is projected on the outer surface of the glass 2 to detect a reflected laser beam, and the distance to the outer surface of the glass 2 is determined. A distance measuring device 20 for measuring is provided. Reference numeral 30 denotes a hanger carriage for adjusting the glass position for adjusting the surface position of the glass 2 in a suspended state.

The measuring cart 10 is assembled in a rectangular parallelepiped shape by, for example, a frame material, and has a caster 1 with a stop function at a lower portion for sequentially moving in front of the respective glasses 2, 2,.
1 is provided. A plurality of, for example, five laser distance meters 21A, 21B... Are mounted on the front surface of the carriage 10 in the height direction and the glass width direction. As described above, a plurality of the laser rangefinders 21A, 21B,... Are attached in a projection direction orthogonal to the glass 2, and the laser light L is projected on the outer surface of the glass 2, the reflected laser light is detected, and the glass is detected. 2 detects the distance to the outer surface, and a commercial product can be used as it is. Each laser rangefinders 21A, the signal from 21B ... as position adjusting information as is, or in the signal processed by the analyzer 22, (parallelism between the particular reference laser beam L ₀₎ plane angle of the glass 2 Ya The position deviation from the other glass 2 surface can be displayed and used as position adjustment information.

On the other hand, since it is important that the measuring cart 10 is orthogonal to the reference laser beam L ₀ , the positioning scales 12, 12 are provided on both side frames to position the measuring cart 10. Is provided. The scale 12 is transparent at least on the side of the reference laser beam emitting device 3, is suspended with play from the upper frame via the suspension pins 13, and has a weight 12 a at the lower portion. Also, the parallel scale 12 is symmetrically arranged vertically from the center in the width direction.
b is displayed. The mounting positions of the scales 12 and 12 are the same in the indoor and outdoor directions.

Thus, the visible reference laser light L ₀ is emitted, and the visible reference laser light L ₀
By positioning the measurement trolley 10 so that the center of 12 is irradiated, the measurement trolley 10 can be positioned and set at the reference position.
