JPH11280342A - Inspection method of execution precision of entrance/exit frame, and inspection tool for execution precision - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enable a rapid and precise inspection by judging the execution precision of an entrance/exit frame by watching the crossing condition of threads extended on the two diagonal lines of the entrance/exit frame respectively and a thread of a plumb bob suspended down to pass through the breadthwise center of the frame. SOLUTION: Two inspection tools A for execution precision to which fitting bodies of threads are attached at both ends of length-adjustable holding rods 2 are horizontally arranged at both upper and lower sides, and the holding rods 2 are stretched to press the fitting bodies of the threads formed at both ends of the holding rods 2 on the inside face of the right and left vertical frame members 4a of the entrance/exit frame 1 to fix the frame 1 to the four corners. Threads 12, 13 are extended between the fitting bodies of the threads positioned on the diagonal lines of the frame 1 and tied to the root parts of hooking pins of the fitting bodies. Then, the thread 15 of a plumb bob 14 is connected to the center of the upper inspection tool A for execution precision and suspended down therefrom. The execution precision of the entrance/exit frame 1 is judged by the crossing condition of the diagonal threads 12, 13 and the perpendicularly hung thread 15. In this way, rapid and precise inspection can be carried out for oneself.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a construction accuracy inspection tool A for inspecting the quality of the construction accuracy of the access frame 1. The construction accuracy inspection tool A is provided with a thread attachment body 3 at both ends of a length-adjustable holding rod 2. Is configured. The access frame 1 is composed of an upper horizontal frame member 4 and a pair of left and right vertical frame members 4a as shown in FIG. 1, and the access frame 1 is attached to an opening C of a partition wall B as shown in FIG. The lower end of the vertical frame member 4a of the access frame 1 is continuous with the floor surface D.

The holding rod 2 is provided for inserting the inner pipe 6 into the outer pipe 5, projecting a part of the inner pipe 6 from one end of the outer pipe 5, and fixing the inner pipe 6 to a desired length. The part 7 is provided at one end of the outer pipe 5, and the entire length of the holding rod 2 can be adjusted by adjusting the protruding length of the inner pipe 6 from the end of the outer pipe 5. I have. At both ends of the holding rod 2, thread mounts 3 made of cubic wood pieces are fixed. A hook pin 9 is implanted in the center of the front portion 8 of the thread mount 3, and a non-slip 10 is attached to an outer surface of the thread mount 3 which is a contact surface with the access frame 1. I have. The anti-slip 10 is formed of a rubber sheet having an uneven surface.

Next, a construction accuracy inspection method using the construction accuracy inspection tool A configured as described above will be described. (1) As shown in FIG. 2, after the two construction accuracy inspection tools A are positioned horizontally above and below the access frame 1, the holding rods 2 of each construction accuracy inspection tool A are extended to attach the left and right yarns. The body 3 is pressed against the inner surfaces of the left and right vertical frame members 4a of the access frame 1, respectively.
The non-slip 11 of the thread mount 3 is frictionally engaged with the inner surface of the vertical frame member 4 a of the access frame 1, thereby fixing the thread mount 3 to the four corners of the access frame 1. At this time, as shown in FIG. 2, the front part 8 of the thread attachment 3 of the construction accuracy inspection tool A and the front part 11 of the access frame 1 are kept flush.

(2) Next, as shown in FIG.
Yarns (hereinafter referred to as “diagonal yarns”) 12 and 13 are stretched between the yarn attaching bodies 3 and 3 located on the diagonal lines of
Is connected to the root of the hook pin 9 of the thread attachment 3. (3) Next, a thread (hereinafter referred to as a “hanging thread”) 15 of the down swing 14 is attached to the center of the construction accuracy inspection tool A located on the upper side, and the down swing 14 is hung. Reference numeral 16 denotes a conical weight of the plunger 13.

(4) Next, the diagonal threads 12, 13 and the hanging thread 1
5 is viewed from the front and side surfaces of the access frame 1 to judge whether or not the construction accuracy of the access frame 1 is good. As shown in FIG. 3, in the case of the entry / exit frame 1 having a diagonal defect, when the entry / exit frame 1 is viewed from the front side, the three threads of the diagonal threads 12, 13 and the hanging thread 15 do not intersect at one point. The three diagonal threads 12 and 13 and the hanging thread 15 form a triangle. On the other hand, FIG.
As shown in FIG.
If the three yarns 3 and the hanging yarn 15 intersect at one point,
It can be determined that the diagonal of the access frame 1 is normal.

As shown in FIG. 5, when the access frame 1 is inclined forward, the two diagonal threads 12 and 13 overlap, but the hanging thread 15 separates from the diagonal threads 12 and 13. . On the other hand, as shown in FIG. 6, if the diagonal threads 12, 13 and the hanging thread 15 overlap when viewed from the side of the
Can be determined to be normal.

When the access frame 1 is inclined backward, the hanging thread 15 is caught by the diagonal threads 12 and 13 and is broken.
When the inclination of the access frame 1 is small, the drooping thread 1
It is difficult to judge whether the number 5 is broken. Therefore, the construction accuracy inspection tool A is set on the back side of the access frame 1, and the diagonal thread 12,
What is necessary is just to judge whether the 13 and the hanging thread 15 separate.

If the two diagonal threads 12 and 13 do not cross on the same plane, it can be determined that the access frame 1 is twisted. In addition, as the yarns 12, 13, and 15, a cotton yarn, a nylon yarn, a piano wire, or the like used as a water yarn is employed.

FIG. 7 shows a down swing holder 17 detachably attached to the upper portion of the center of the upper horizontal frame member 4 using the double-sided adhesive tape or the like. It shows a state in which it hangs down. In this way, the downward swing 13 does not have to be applied to the construction accuracy inspection tool A located on the upper side.

[0018]

As described above, according to the method for inspecting the construction accuracy of the access frame according to the first aspect of the present invention, the yarns are respectively stretched on two diagonal lines of the access frame, and the width of the access frame in the width direction of the access frame is determined. Inspection of the diagonal and construction of the entrance / exit frame from the intersection of the yarn when the yarn passing through the center is hung from the top of the entrance / exit frame, and it is possible to accurately judge the quality of the construction accuracy of the entrance / exit frame, and by itself Can be inspected.

According to the construction accuracy inspection method of the access frame according to the second aspect of the present invention, each holding rod is extended to dispose the thread mounting members at the four corners of the access frame, and the yarn is stretched between the thread mounting members. Therefore, the thread can be stretched on the access frame without using a fixing tool such as a nail.

According to the third embodiment of the present invention, the holding rod is extended and installed between the vertical frame members of the access frame, so that the thread can be attached without using a fixing tool such as a nail. The body can be arranged at the corner of the access frame, and the work of arranging the thread attachment body becomes easy.

According to the inspection tool for construction accuracy of the access frame according to the fourth aspect of the present invention, since the hook pin protrudes from the center of the front portion of the thread mounting body, the thread is stretched only by hooking the end of the thread on the hook pin. And the work of stretching the thread is facilitated.

According to the construction accuracy inspection tool of the access frame according to the fifth aspect of the present invention, since the anti-slip is provided on the frame contact surface of the thread attachment body, the construction accuracy inspection tool set on the access frame is inadvertently shifted. Disappears.
