Description

[Detailed description of the invention] a. Purpose of the invention (industrial field of application) The gauge for sash frame installation work according to this invention is:
Used when installing a sash frame inside the opening of a building at a construction site.

(Prior art) When installing a metal window frame such as aluminum sash into a window opening of a reinforced concrete building, the 9th
~ As shown in Figure 10, the sash frame 1 is inserted inside a window opening 2 formed slightly larger than the outer circumferential surface of the sash frame 1, and the reinforcing bars exposed on the inner circumferential surface of the window opening 2 are inserted. and an anchor (not shown) fixed to the outer peripheral surface of the sash frame 1 are welded, and then mortar is poured into the gap 3 formed between the outer peripheral surface of the sash frame 1 and the inner peripheral surface of the window opening 2. It is poured to close the gap 3 and firmly fix the sash frame 1 inside the window opening 2.

By the way, in this way, the sash frame 1 is connected to the window opening 2.
If the sash frame 1 is not fixed vertically, it will not only make the window shoji look unsightly and make it difficult to open and close the window shoji smoothly, but also prevent the finish inside the building from being If the position of the sash frame 1 attached to the sash frame 1 is used as a reference, the reference becomes vague and the above-mentioned finishing etc. cannot be performed correctly.

For this reason, conventionally, thread 30 as shown in FIG.
Using a tool with an inverted cone-shaped weight 31 tied to the end, a work called plumb bobbing was performed to ensure that the sash frame 1 attached to the inside of the window opening 2 was properly vertical.

When performing this work called plumb swing, the thread 30 is attached near the front (or rear) of the sash frame 1.
is hung down, and the inclination of the sash frame 1 in the front and back directions in the drawing is adjusted so that the thread 30 and the front (or rear) surface of the sash frame 1 are parallel to each other. Also, the above thread 3
0 is also hung on a portion close to the outer circumferential surface of the sash frame 1 so that this outer circumferential surface and the thread 30 are parallel to each other.

However, when correcting the inclination of the sash frame 1 by the above-mentioned work called plumb bobbing, not only is the work troublesome and requires skill, but it also becomes difficult to carry out the work on windy days. Efficiency will deteriorate.

In order to solve this kind of inconvenience, for example,
61-191755 has been proposed.

As shown in Fig. 2, the above-mentioned installation work gauge has two inclinometers 5a, 5b mounted on a casing 4 having a rectangular cross section of the same size from the upper end to the lower end, and the measuring direction of both inclinometers 5a, 5b. The indicator panels 6a and 6b of both the inclinometers 5a and 5b are mounted on the sides 7a and 7a of the casing 4, respectively, so as to be shifted at right angles to each other.
7b so that the measured values of each inclinometer 5a, 5b can be read from the outside of the casing 4.

When attaching the sash frame 1 to the window opening 2 using the installation gauge 9 configured as described above, the gauge 9 is mounted parallel to the vertical frame of the sash frame 1, and the gauge 9 is mounted parallel to the vertical frame of the sash frame 1. Attach the sash frame 1 with the sash frame 9 still attached.

When the sash frame 1 is tilted, the indication panels 6a and 6b of one or both of the inclinometers 5a and 5b indicate that the vertical frame of the sash frame 1 is tilted and the direction of the inclination. Therefore, by adjusting the mounting posture of the sash frame 1 so that the indicator panels 6a and 6b of both the inclinometers 5a and 5b indicate that the vertical frame is not tilted, the sash frame 1 can be adjusted. It can be installed correctly and vertically in the window opening 2.

(Problems to be Solved by the Invention) However, even with the gauge 9 for vertical member attachment work as described above, there are still problems to be solved as described below.

That is, the gauge 9 must be mounted parallel to the vertical frames 36, 36 of the sash frame 1 (see FIG. 9). For this purpose, for example, support pins 22, 22 and a restraining cam 23 (see Figs. 2 and 3) are provided at both upper and lower ends of the side surface of the casing 4 constituting the mounting gauge 9. The gauge 9 can be mounted parallel to the sash frame 1 by strongly sandwiching the protrusions 21 (see Fig. 8), which have equal protrusion amounts, on both the upper and lower frames of the sash frame 1 between the cam 23 and the cam 23. I have to.

However, the support pins 22, 2 as described above
When the gauge 9 is mounted on the sash frame 1 using the holding cam 23 and the sash frame 23, the inner surfaces of the gauge 9 and the side surfaces of the sash frame 1, which face each other, are parallel to each other. It is not necessarily parallel to the vertical frame 36.

In this way, while the gauge 9 is mounted non-parallel to the left and right vertical frames 36 of the sash frame 1,
Even if this sash frame 1 is installed within the window opening 2, the sash frame 1 cannot be installed perpendicularly to the window opening 2.

The gauge for sash frame installation work of the present invention solves the above-mentioned inconveniences, and when this gauge is attached to the sash frame, the sides of the sash frame that are opposite to each other and the inside surface of the gauge become parallel, and this The parallelism between the gauge and the vertical frame constituting the sash frame can be easily adjusted.

b. Structure of the invention (means for solving the problem) The gauge for sash frame installation work of the invention is similar to the gauge of the previous invention, in which the casing has a rectangular cross section of the same size from the upper end to the lower end, and two inclined The measurement directions of both inclinometers are shifted at right angles to each other, and the indicator panels of both inclinometers are exposed on the side of the casing, so that the measured values of each inclinometer can be read from the outside of the casing. The main body of the gauge is constructed in the following manner.

Furthermore, in the gauge for attaching the sash frame of the present invention, brackets are provided at two positions above and below the gauge body so as to project to the sides of the gauge body by the same length.

Means for attaching the upper and lower ends of the gauge body to the upper and lower frames constituting the sash frame is provided on a surface perpendicular to the projecting direction of the bracket.

(Function) When installing a sash frame using the sash frame installation gauge of the present invention constructed as described above, the main body is attached to the sash frame to be fixed vertically, similar to the gauge of the previous invention. Attach the devised gauges in parallel. That is, by attaching the upper and lower ends of the gauge body constituting the gauge to the upper and lower frames of the sash frame, the side surfaces of the sash frame and the inner surface of the gauge, which are opposed to each other, are made parallel.

At this time, the ends of the two upper and lower brackets attached to the gauge body are brought into contact with the vertical frame constituting the sash frame, thereby making the gauge body and the vertical frame parallel.

Once the gauge body and the vertical frame constituting the sash frame are made parallel to each other in this way, the sash frame is attached with the gauge body still attached to the sash frame.

(Example) Next, the present invention will be explained in more detail by explaining the illustrated embodiment.

FIG. 1 is a side view of the upper end of the gauge for attaching the sash frame of the present invention.

The gauge for attaching the sash frame of the present invention, like the gauge of the previous design shown in Fig. 2, is made by integrally extruding aluminum material, and has a casing with a square cross section of the same size from the upper end to the lower end. 4, two inclinometers 5a and 5b are built in with the measurement directions of both inclinometers 5a and 5b being shifted at right angles to each other.

Indication panels 6a, 6b of the above-mentioned both inclinometers 5a, 5b
are the mutually adjacent side surfaces 7 of the casing 4
a, 7b so that the measured values of each inclinometer 5a, 5b can be read from the outside of the casing 4.

Each of the inclinometers 5a and 5b mechanically or electrically amplifies the inclination of a rod with a weight suspended from its lower end to move the pointers on the indicator panels 6a and 6b. Use what you have. Such inclinometers 5a, 5b are provided with knobs 8, 8 for immobilizing the pointer, a knob (not shown) for adjusting the zero point of the pointer, and the like.

Furthermore, in the gauge 9 for sash frame installation work of the present invention, the casing 4 constituting this gauge 9 is
and the vertical frame 36 of the sash frame to be fixed vertically,
Brackets 34 for mounting the gauge 9 on the sash frame 1 so as to be parallel to each other are attached to both upper and lower ends of the gauge body so as to be freely attachable and detachable by rotating a set screw 37.

That is, as shown in FIG. 1, when the bracket 34 is fixed to the end of the gauge body by tightening the set screw 37, it protrudes by a certain length from the side surface of the casing 4 forming the gauge body. It consists of

Furthermore, in the illustrated embodiment, like the previously devised installation work gauge described above, there is a telescoping mechanism that allows this gauge 9 to be attached to sash frames of different heights, and a telescoping mechanism that allows this gauge 9 to be mounted on sash frames of different heights. Attachment/detachment mechanism for easy and quick attachment/detachment work;
A support mechanism is also incorporated to keep the casing 4 parallel to the reference wall surface when zeroing the pointers of the inclinometers 5a, 5b.

The expansion and contraction mechanism among these will be explained first. Third
As shown in the figure, a support member 10 having an L-shaped cross section is slidably inserted into a casing 4 having a square cross section. When the support member 10 is inserted, the outer surface of the support member 10 and the inner surface of the corner of the casing 4 come into close contact, so that the support member 10 and the casing 4 are linearly connected to each other.

At the tip of the support member 10 that protrudes from the casing 4, there is an end block 11 whose outer periphery is formed to have the same shape and size as the outer periphery of the casing 4.
It is fixed with countersunk screws 12, 12.

On the other hand, a restraining block 13 having a U-shaped cross section by connecting a pair of parallel walls 13a and 13b with a connecting wall 13c is inserted inside the end of the casing 4, and the outer surface of this restraining block 13 and , and the inner circumferential surface of the casing 4, the supporting material 10 can be held down.

Parallel walls 13a, 13b of the holding block 13
Among them, screw holes 15 into which the tips of fixing screws 14 (only one is shown, but two are actually used) are screwed at two positions, upper and lower, of the parallel wall 13a that abuts the support member 10. , 15 is the other parallel wall 13b
has a through hole 16 through which the fixing screw 14 is inserted.
are drilled in each. Also, both parallel walls 13
Another fixing screw 17 (as in the case of the above fixing screw 14) is attached to the connecting wall 13c that connects a and 13b.
Although only one is shown in the diagram, two are actually used. )
Screw holes 18, 18 are formed for screwing the tips of the.

On the other hand, at the upper end of the casing 4, a through hole 16 or a screw hole 18 formed in the restraining block 13,
The fixing screws 14, 1
By drilling through holes 19 and 20 through which 7 can be inserted,
Fixing screws 14 and 17 inserted into the casing 4 from the outside of the casing 4 are inserted into the screw holes 1, respectively.
It is designed so that it can be screwed into parts 5 and 18. The portions where each of the fixing screws 14 and 17 pass through the casing 4 are configured such that each of the fixing screws 14 and 17 can rotate, but cannot move in the length direction.

Therefore, by rotating each of the fixing screws 14 and 17, the distance between the outer surface of the holding block 13 and the inner peripheral surface of the casing 4 can be changed in the length direction of the support material 10 sandwiched between both surfaces. It is possible to freely slide over the range, or to disable such sliding. Incidentally, when such a telescopic mechanism is employed, one side of the bracket 34 can be freely attached to the end of the support member 10.

Next, a description will be given of an attachment/detachment mechanism for easily and quickly attaching and detaching the gauge 9 to and from the sash frame 1.

The sash frame 1 to which the gauge 9 of the present invention can be attached and detached by the attachment/detachment mechanism described below has an upper frame 32 and a lower frame 33 that constitute the sash frame 1, as shown in FIG.
It is necessary that protrusions 21, 21 are fixedly installed on the interior side of the room.

The attachment/detachment mechanism for attaching and detaching the gauge 9 of the present invention to and from the sash frame 1 having the upper frame 32 and lower frame 33 on which the protrusions 21, 21 are fixedly attached is an end block as shown in FIG. 11 or the outer peripheral surface of the casing 4 (the side where the end block 11 is not provided), a pair (two pairs in total) of support pins 22, 22 provided at the same height, and this support pin. 22, and a restraining cam 23 rotatably supported on a pivot shaft 24 provided near the cams 22, 22. The above axis 24
supports the off-center portion of the holding cam 23, so when the holding cam 23 is rotated,
The size of the gap existing between the straight line connecting the support pins 22, 22 and the outer peripheral surface of the holding cam 23 changes, and the protrusion 21 inserted into this gap changes.
can be strongly pinched. However, the support pins 22, 22 facing the holding cam 23 do not necessarily have to be a set of two, and only one long bank-like pin (two in total above and below) may be provided.

Furthermore, in this embodiment, as shown in FIGS. 5 and 6, in addition to the above-mentioned attachment/detachment mechanism, the end block 11
The magnet 3 is placed on the top surface and the bottom surface of the bottom surface 25 in a direction perpendicular to the protruding direction of the bracket 34 mentioned above.
If the sash frame 1 is made of iron, the magnets 35, 35 can also be used to attach a gauge for the sash frame installation work to the sash frame 1.

Next, inclinometers 5a and 5 installed inside the casing 4
When adjusting the zero point of the pointer b, casing 4
The support mechanism for keeping the wall parallel to the reference wall will be explained.

End block 11 fixed to the end of support 10
An X-shaped recess 26 is formed in the upper surface (or the lower surface of the bottom plate 25 that closes the lower end opening of the casing 4) in the diagonal direction. Projecting plates 27, 27 of different shapes and sizes are fitted in such a way that they can slide in the length direction without rattling.

Elongated holes 28, 28 of the same length are bored in each of the protruding plates 27, 27, respectively.
Set screws 29, 29 inserted from above through the long holes 28, 28 of 27 are screwed into screw holes formed in the upper surface of the end block 11 (or the lower surface of the bottom plate 25). The screwing position of each set screw 29, 29 is such that each protruding plate 27, 27 is connected to the above set screw 29,
29 is moved outward until it abuts the ends of the elongated holes 28, 28, the tips of the respective protruding plates 27, 27 protrude by the same amount from the outer peripheral surface of the end block 11 (or the bottom plate 25). I'm positioning it so that it will work.

When installing the sash frame 1 as shown in FIG. 8 using the sash frame mounting gauge 9 of the present invention constructed as described above, first the gauge 9 is
Adjust the length of to the height of Satsushi frame 1.

When adjusting the length of the gauge 9 like this, loosen the fixing screws 14 and 17 screwed into the screw holes 15 and 18 of the holding block 13, and make sure that the outer surface of the holding block 13 and the inner peripheral surface of the casing 4 are aligned. The distance between the supporting members 10 and 10 is increased so that the supporting member 10 can freely slide with respect to the casing 4. If the support member 10 is slid against the casing 4 in this state, the amount of protrusion of the support member 10 from the casing 4 changes, and the overall length of the gauge 9 can be adjusted.

Once the overall length of the gauge 9 has been adjusted to match the height of the sash frame 1, the holding block 1 can be adjusted by rotating the fixing screws 14 and 17 in the opposite direction to the above case.
The distance between the outer surface of the casing 3 and the inner circumferential surface of the casing 4 is narrowed, and the support member 10 is strongly held between the two surfaces.
The supporting member 10 is made unable to slide relative to the casing 4, and the entire length of the gauge 9 is fixed (see FIG. 4).

If the overall length of the gauge 9 is adjusted to match the height of the sash frame 1 in this way, then the protrusion 2 of the sash frame 1
1 and 21 are inserted between the support pins 22 and 22 provided at the upper and lower ends of the gauge 9, respectively, and the holding cam 23. At this time, the brackets 34 attached to the vertical frame 36 of the sash frame 1 are attached to the upper and lower parts of the gauge body.
The position of this gauge 9 is determined by touching the tip of the gauge. In addition, during this insertion work, the support pins 22, 22
The width of the gap between the straight line connecting the lines and the outer peripheral surface of the holding cam 23 is made large.

Projections 21, 21 provided individually on both upper and lower frames 32, 33 constituting the sash frame 1 are connected to support pins 22, 22 provided at both upper and lower ends of the gauge 9, and a holding cam 2.
3, the width of the gap is reduced by rotating the restraining cam 23. By this work, the above protrusion 2
1 and 21 are strongly sandwiched between the support pins 22 and 22 and the outer peripheral surface of the holding cam 23, and the gauge 9 is firmly attached to the sash frame 1. Also, in this state, the inner surfaces of the gauge 9 and the indoor side surfaces of the sash frame 1, which face each other, are parallel to each other, and the gauge 9 and the vertical frame 36 constituting the sash frame 1 are arranged so that the amount of protrusion of the bracket 34 is be parallel to each other with a distance corresponding to .

In this way, for the vertical frame 36 of the satsushi frame 1,
If the gauge 9 of the present invention is installed in parallel, the seventh
As shown in the figure, the sash frame 1 is installed with the gauge 9 still attached.

If the sash frame 1 to be installed is tilted,
Two inclinometers 5a, 5 built into the casing 4
Indicator panel 6 of either or both of b.
Since it is possible to know from a and 6b that the sash frame 1 is tilted and the direction of inclination, the indicator panels 6a and 6b of both the inclinometers 5a and 5b indicate that the sash frame 1 is not tilted. By adjusting the mounting posture of the sash frame 1 as indicated, the sash frame 1 can be properly vertical no matter which direction it is placed.

If the indicated values of the inclinometers 5a and 5b incorporated in the gauge 9 of the present invention constructed and used as described above are incorrect (zero point adjustment is not done correctly), the installation of the sash frame 1 Therefore, in the illustrated embodiment, the zero point adjustment of each inclinometer 5a, 5b is performed as follows.

That is, when performing the zero point adjustment work, first, a total of eight protruding plates 27, 27, each set of four attached to the upper surface of the end block 11 and the lower surface of the bottom plate 25, are made to protrude outward from the casing 4. , set screw 2
Each protruding plate 27, 27 is fixed by tightening the parts 9, 29.

In this state, one side of the casing 4 is opposed to a suitable wall surface, and the tips of the upper and lower protruding plates 27, 27 are brought into contact with the wall surface, so that the casing 4 and the wall surface are parallel to each other. The inclination angle of this wall surface is measured by an inclinometer 5a (or 5b) that indicates the inclination angle of the surface. Next, the casing 4 is turned over and the same operation is performed again.

If the zero point adjustment of the inclinometer 5a (or 5b) is performed correctly, even if the inclination angle measurement of the same wall surface is performed with the casing 4 turned over, the absolute value of the measured value will be the same, but the zero point adjustment If this is not done correctly, there will be a difference in the absolute values of the above measured values.

Therefore, if the zero point is adjusted so that the absolute value of the measured value when the front side of the casing 4 faces the wall is equal to the absolute value of the measured value when the back side faces the same, each inclinometer The zero points of 5a and 5b can be adjusted correctly.

Note that the structure for mounting the gauge 9 of the present invention on the sash frame 1 is not limited to that of the illustrated embodiment, and various other structures may be adopted.

c. Effects of the invention The gauge for sash frame installation work of the present invention is configured and operates as described above, so that the sash frame can be positioned easily and quickly, and moreover, it can be used even when the wind is blowing. Since positioning work can be performed without any hindrance, it plays a major role in streamlining construction work.
