Description

[Detailed Description of the Invention] The present invention relates to an architectural sighting device for measuring the horizontal direction of foundations and foundations and the vertical direction of columns, etc. when constructing a building.

The purpose of this invention is to propose a new architectural sighting device that can easily and accurately measure the horizontal direction of foundations and foundations and the vertical direction of columns when constructing foundations and foundations and constructing pillar structures at construction sites. It's about doing.

The device of the present invention, which is a distant relative of this purpose, has a support frame suspended from an underframe supported by three telescopic support legs so as to be swingable in all directions, front, rear, left, and right. A vertical sight whose main body is a vertically long rod-like body is attached and supported on the frame, and a weight is provided to hold the main body in a vertical position. A water fan sight equipped with a spirit level and a telescope is fitted to the main body in a position perpendicular to the main body so that it can freely slide vertically and in the rotational direction. It is characterized by being rotatably supported by a support metal fitting that can be fitted in an adjustable manner.

Next, an example of implementation will be described in detail based on the drawings.

In Fig. 1, reference numeral 1 denotes an underframe, which is formed into a rectangular tube shape with a top plate 12 on the upper side and an open bottom (Fig. 2). Three telescopic support legs 11... are connected so as to freely rotate in and out.

Reference numeral 2 denotes a support frame body supported on the underframe 1 so as to be swingable in all directions, front, rear, left and right.

The support frame 2 is supported by a pair of support shafts 3, 3 provided at the front and rear of the underframe 1 (vertical direction in FIG. 3), and can be moved left and right (in the direction of the arrow) around the axis Y of the support shafts 3, 3. A base plate 2L is mounted with a rectangular frame body 20 supported via bearing members 4, 4 so as to swing, and a base plate 2L on which a sighting device 5 whose main body 50 is a vertically long pipe used as a reference line in the vertical direction is mounted. The weight 22 is formed into a vertically long cylindrical shape and arranged at the center of the frame 20,
And by a pair of support shafts 6.6 provided on the left and right sides of the frame 20,
Front and back (in the direction of the arrow) around the axis X of the support shafts 6, 6
The weight 22 is supported via a locking rod 23 penetrating from side to side so as to swing, and the upper end 22a of the weight 22 is made to protrude upward from a through hole 13 provided in the top plate 12 of the underframe 1.
The above-mentioned base plate 21 is integrally mounted on the protrusion.

In this embodiment, for convenience in carrying, a female thread 21a is provided at the center of the base 21, and a thread 5a is provided at the lower end on which the sight 5 is attached. By screwing together the male screw 5a 21a, they can be assembled straight into one piece.

7 and 8 are the frame body 20 that swings around the axis Y and the axis X.
A weight 22 that swings around
In the locking device 7 for fixing the frame 20 to 2
There is also a structure in which the locking plate 4a is fixed by abutting against the outer peripheral edge of the locking plate 4a provided at 0, and the locking is released by releasing the locking plate 4a (71M, 2-
17'q A lock device 8 for fixing the plumb weight 22 is attached to the lock device 8. Similar to the lock device 7 above, the tip of a threaded rod 82 with four grooves 81 protruding from the outside of the underframe 1 is attached to the lock device 8 provided on the weight 22. Stop plate 2
It is configured to be fixed by coming into contact with the outer peripheral edge of 3a, and to be released from being fixed by separating it.

In addition, in this embodiment, the locking plates 4a and 23a are connected to the bearing member 4 provided on the axis Y and the locking rod 2 provided on the axis X.
Although it is integrally formed using the members of No. 3, other appropriate means may be used.

9 is a horizontally long main case 90 with a spirit level 91 for leveling.
．． 91 on the left and right, and a telescope 92 on one end side.
A horizontal sight equipped with a horizontal sight, the main case 9 of which is
0 is inserted so as to be vertically and rotatably perpendicular to the main body 50 of the sight 5 used as the vertical ruler.

And a band-shaped support fitting 51 installed on the main body 50
It is mounted and supported so that it can freely rotate 360 degrees in the supported state (position) by and by moving the supporting metal fitting 51 up and down with respect to the main body 50, the horizontal sight 9 can move up and down accordingly. The height position of the horizontal sight 9 is adjusted by vertically adjusting the support fitting 51.

Next, to explain the function and effect, the architectural sighting device A according to the present invention configured as described above can be carried to the site and installed at the measuring place with the supporting legs 11 open. 2 swings back and forth and left and right around the axes X and Y until it gradually stabilizes and stops, so if the support frame 2 is fixed by each locking device 7 and 8 at the point where it stops, it will be long vertically. The main body 50 of the sight 5 is now centered in the correct vertical position.

Since the horizontally long horizontal sight 9 is fitted so that it can freely rotate in a state that is correctly perpendicular to the main body 50 of the vertically long sight 5 described above, the support metal fitting 51 can be adjusted up and down. By adjusting the displacement to a predetermined height position and rotating the horizontal sight 9 while looking through the telescope 92, it is possible to measure the horizontal level of a long horizontally continuous foundation or base at one time. become.

Furthermore, at this time, it is possible to check whether the telescope 92 is rotating along a horizontal plane while checking with the spirit level 91, so that accurate measurements can be made.

The main body 50 of the above-mentioned vertical sight 5 supports the horizontal sight 9 in a vertically adjustable manner.
As mentioned above, the main body 50 is vertically elongated and held in a vertical state, so when constructing a column on the foundation/foundation, the side edge of the column can be visually checked using the side edge of this main body 50 as a reference line. By twisting them together, you can easily make the pillars vertical, and the verticality in this case is because the main body 50 is vertically long.
It is accurate because it can detect even the slightest inclination of the pillar.

Therefore, according to the present invention, it becomes possible to easily and accurately determine the horizontality of the foundation/foundation and the verticality of the columns.
