DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adjusting method for adjusting the amount of window glass entering and exiting so as to maintain a constant attitude with respect to a building wall serving as a reference plane.

[0002]

2. Description of the Related Art In recent buildings such as commercial buildings, a heat ray absorbing glass is often used as a window glass for the purpose of saving labor. In this case, a mirror effect occurs on the window glass and reflects the surrounding scenery.

However, in this type of window glass, if the adjacent window glasses are not aligned on the same plane, the reflection angle of the scenery differs between the adjacent window glasses, and the reflected image is distorted or discontinuous. This does not significantly affect the function of the building itself, but is not preferable from an aesthetic point of view such as harmony with the surrounding landscape. Depending on the location, the orientation of the reflected light from the building may be restricted due to antiglare considerations.

Therefore, after the building is finished, the final position of the window glass is adjusted. Conventionally, a supervisor instructs a joiner worker standing by near the relevant window to use a transceiver or the like to indicate the correction direction while observing the shift of the image between adjacent window glasses that can be seen from the outside, and then enters and exits based on that. Fine adjustments were made to the final position while making adjustments and repeating trial and error.

[0005] In addition, a technique has been developed in which a shadow image is projected on a television camera in place of an observer to observe the shift and the amount thereof.

[0006]

However, in any of these methods, there is no absolute standard for position adjustment, so that the method must be trial and error, and communication at the site is inconveniently transmitted. Coordination took a lot of time and effort because of misunderstandings at times.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to quantify the front and rear displacement of a window glass with the outer wall as a reference plane, and to easily correct entrance and exit based on the numerical value. The present invention provides a method for adjusting a window glass.

[0008]

In order to achieve the above-mentioned object, the present invention relates to a method of attaching a reflection sheet to at least three horizontal and vertical directions at corners of a window glass to be measured. Using a three-dimensional position measuring device installed at a fixed position away from the building in which the building is built, measure the position due to reflection from each of the reflection sheets, and use the building wall surface or a plane parallel to the building wall as a reference value for a window. A distance from the position data at the position on the glass surface is calculated, and the calculation result is numerically displayed as an out-of-plane amount of the window glass.

According to the present invention, a three-dimensional position data of a building wall is measured by attaching a reflection sheet to the peripheral wall.
Using this three-dimensional position data as a reference value, calculate a plane including all the positions of the reflecting sheet on the wall surface or a plane parallel thereto, calculate the distance between this plane and the three-dimensional position data at the position of the window glass surface, This calculation result can be numerically displayed as an out-of-plane direction of the window glass.

[0010]

According to the above arrangement, if the window glass at the current position is adjusted in and out of the plane by a numerical value corresponding to the displayed amount of in and out, each glass surface is completely coplanar. Is done.

In the case of the configuration of claim 2, it becomes possible to install the three-dimensional position measuring device at an arbitrary position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is an explanatory view of the method of the present invention. The three-dimensional measuring device 3 is located at a position distant from the building 1 with each one of a large number of window glasses 2 arranged on the outer wall 1a of the building 1 as an object to be measured. Is installed.

At three corners of the window glass 2 to be measured, the reflecting sheets 4a, 4b, 4
c is adhered, and the reflection sheets 5a, 5b, 5c are also adhered to the surface of the outer wall 1a around the window glass 2, and the positions of the respective reflection sheets 4a,. 3 to measure.

The three-dimensional measuring device 3 comprises an apparatus main body 6 and a computer 7 connected to the apparatus main body 6 and constituting a system for calculating a three-dimensional position.

The apparatus main body 6 includes an optical pulse range finder 9 which is tiltably supported by a support arm 8 which is pivotally mounted on a table mounted at the fixed point position.

The optical pulse range finder 9 has a pulse laser emitting section, a light receiving section, a CCD camera and the like arranged in a telescopic casing.

The pulse light from the laser emitting section of the optical pulse rangefinder 9 is reflected by the reflection sheets 4a,..., 5a, and the reflected image is received by the light receiving section via a lens to form a bright spot. Received. That is, the azimuth angle, the elevation angle, and the distance with respect to the reflection sheets 4a,. Further, the CCD camera captures an image of a scene overlapping the reflection sheet 4.

The reflection sheet 5 attached to the outer wall 1a
a, 5b, and 5c are reference surfaces for determination. On the other hand, the parallelism and the verticality of the window glass 2 do not always coincide with the outer wall 1a. Therefore, the positions of the reflection sheets 4a, 4b, and 4c are fixed distances from the reference plane by the inclination of the window glass 2. However, by processing this value by the computer 7, the in-and-out amount is grasped numerically.

The computer 7 is composed of an arithmetic unit 7a, a keyboard 7b, a display 7c, etc. The display 7c displays the scenes captured by the CCD camera and the positions of the reflection sheets 4a, 5a, etc. The calculation result of the calculation unit 7a is displayed so as to be superimposed on the screen.

The calculation unit 7a compares the position of the reflection sheet of the window glass 2 with the vertical plane including the wall surface of the outer wall 1a as a reference value, calculates the distance, and displays the result on the display 7c.

As an example, the three-dimensional positions of the reflection sheets 5a, 5b, and 5c on the outer wall 1a are A, B, and C, and the horizontal luminous intensity on the side of the window glass 2 is the reflection sheet 4a. A, 4b, 4c
In the case of ', B', C ', the calculating unit 7a calculates the distances of A', B ', C' to the plane ABC based on the respective detected position information.

The calculation result is displayed on the display 7c as described above.
When the window is retracted by mm, -2 mm is displayed on the upper right side of the screen, and when the upper left of the window glass is retracted by 1 mm, -1 mm or the like is displayed on the upper left of the screen.

Incidentally, the operator who observes the screen of the display 7c communicates with the joiner worker near the corresponding window glass 2 by means of a transceiver, for example, "2 m on the upper right side.
m, 1mm on the upper left ”and confirm that the operator has made the correction based on this, and then perform the re-measurement after the correction to confirm whether the correction was performed correctly. it can.

However, if it is determined that the result of the correction operation based on the calculation result is extremely good, the correction numerical value of the corresponding window glass 2 is stored together with the floor and window position information, and the collective correction is performed later based on the numerical value. You may do the work.

Further, in the embodiment, it has been described that the posture of the window glass 2 is corrected so as to match the outer wall 1a. However, if the orientation of the reflected light from the building 1 is restricted, the outer wall 1a
Is used as a reference plane, and the horizontal and vertical inclinations required for the window glass 2 are programmed in advance with respect to the outer wall 1a as coefficients, and the correction amount is calculated and displayed based on the result. good.

Further, a three-dimensional position measuring device is installed on the basis of the black ink of the core of the building or at a predetermined position with respect to the building position, and a reference plane is set regardless of the reflection sheet on the wall surface. As a reference, the three-dimensional position of the reflection sheet of the window glass may be measured.

[0028]

As described in the above embodiments, in the method for adjusting a window glass according to the present invention, the window glass at the current position is moved in the out-of-plane direction by a numerical value corresponding to the displayed entrance / exit amount. Since the adjustment of the parallelism is completed in accordance with the reference only by the work of adjusting the access, the adjustment can be performed quickly and accurately in one operation without repeating the conventional trial and error.
