[0001]
BACKGROUND OF THE INVENTION
The present invention is used when constructing an entrance / exit frame without a sill such as a house, and when performing an operation of fixing the lower part of the entrance / exit frame to a floor surface, the interval between the lower parts of the vertical frame is set to a predetermined distance. It relates to a temporary width stop jig for supporting the head.
[0002]
[Prior art]
Normally, when constructing an entrance / exit frame without a sill, the vertical frames on both sides and the duck are assembled and then attached to the outside of the vertical frame by staking the supporting pillars. At this time, if a door is attached to the entrance / exit frame, the door is also attached. After that, the assembled entrance / exit frame is vertically raised and positioned at a predetermined position, and then fixed by nailed diagonally from the side surface of the accessory post toward the floor surface.
[0003]
In such an entrance / exit frame without a sill, the lower part of the vertical frame is not connected by a sill. It was difficult to keep the interval of the opening width of the entrance / exit frame that is the original interval. Therefore, conventionally, as shown in FIG. 10, unnecessary square members or the like are cut to the same length as the opening width D of the entrance / exit frame 4, and the square members are sandwiched between the lower portions of the vertical frame 5 to temporarily provisional widths. Used as a stop 13. Here, the opening width D of the entrance / exit frame 4 is the horizontal distance of the opening of the entrance / exit frame 4 and is the same distance as the original interval between the inner side surfaces 6 of the vertical frame. Say. Also, in the figure, the accessory pillar 7 is attached to the outside of the vertical frame 5.

[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the temporary width stop jig | tool of the entrance / exit frame which concerns on embodiment of this invention is demonstrated based on drawing. As shown in FIG. 1, a temporary width stopper jig 1 for an entrance / exit frame according to a first embodiment of the present invention has a rectangular flat plate-like main body 2 and both longitudinal ends of the main body 2 vertically upward. The contact surface 3 is formed by bending the contact surface 3 and the distance between the contact surfaces 3 on both sides is equal to the opening width of the entrance / exit frame. This will be described in more detail below.
[0010]
As shown in FIG. 1, the temporary width stop jig 1 for the entrance / exit frame is formed by bending both ends in the length direction of a rectangular flat plate. As the material of the rectangular flat plate, it is desirable to use a metal plate from the viewpoint of strength and ease of workability. In this case, a material which does not easily rust, such as a stainless steel plate or a coated or plated iron plate is used.
[0011]
Then, both end portions of the rectangular flat plate-like main body 2 are bent vertically upward to form the contact surface 3. As shown in FIG. 2, the interval between the contact surfaces 3 is formed to be equal to the opening width D of the entrance / exit frame. Here, the opening width D of the entrance / exit frame is a horizontal distance of the opening of the entrance / exit frame, and is the same distance as the original distance between the inner side surfaces 6 of the vertical frame 5 of the entrance / exit frame 4. Say. Since the opening width D of the entrance / exit frame is normally determined in several steps step by step, almost all the entrances / exits are provided by preparing several types of intervals of the abutment surface 3 with a predetermined size accordingly. It is possible to correspond to the frame 4. For example, in a house, three types of 780 mm, 700 mm, and 630 mm are prepared.
[0012]
Although there is no restriction | limiting in particular about the height H of the said contact surface 3, By putting on the floor surface between the lower parts of the said vertical frame 5, it contact | abuts to the inner surface 6 of the said vertical frame 5, and this vertical frame 5 It suffices if a flat surface capable of supporting the inner side surfaces 6 is formed. Therefore, for example, the height H of the upper end of the contact surface 3 may be about 5 mm or more from the bottom surface of the main body 2.
[0013]
Further, the width W of the main body 2 and the abutting surface 3 is not particularly limited, and it is sufficient if the width is sufficient to ensure strength sufficient to support the inner side surfaces 6 of the vertical frame 5. It is. However, in order to stably and reliably support the main body 2 and the contact surface 3, the contact surface 3 can be easily contacted perpendicularly to the inner surface 6 of the vertical frame 5. The width W of the vertical frame 5 should be as wide as possible. Preferably, the width W should be equal to or greater than the width of the inner surface 6 of the vertical frame 5.
[0014]
Next, a method of using the temporary width stopper jig 1 for the entrance / exit frame according to the first embodiment of the present invention will be described. The temporary width stop jig 1 for the entrance / exit frame is used to set an interval between the lower part of the vertical frame 5 of the entrance / exit frame 4 and the opening width D of the entrance / exit frame when constructing an entrance / exit frame 4 such as a house without a threshold. It is used to support. The construction of the entrance / exit frame 4 without such a threshold is normally performed as follows. That is, after assembling the vertical frames 5 and the ducklings on both sides, the supporting pillars 7 are attached to the outside of the vertical frame 5 by nailing. After that, the assembled entrance / exit frame 4 is vertically raised, positioned at a predetermined position, and then fixed obliquely from the side surface of the accessory post 7 toward the floor surface 8. However, in the entrance / exit frame 4 without such a sill, since the lower part of the vertical frame 5 is not connected by the sill, the lower part of the vertical frame 5 may be displaced when being fixed to the floor surface 8 as it is. It was difficult to maintain the interval between the inner side surfaces 6 at the opening width D of the entrance / exit frame, which is the original interval.
[0015]
Therefore, in order to support the space between the inner side surfaces 6 at the lower part of the vertical frame 5 so as to be the opening width D of the entrance / exit frame, the temporary width stopper jig 1 of the entrance / exit frame is set vertically with the entrance / exit frame 4 standing upright. After being raised and before being fixed to the floor surface 8, as shown in FIG. 2, it is placed on the floor surface 8 between the lower portions of the vertical frame 5 of the entrance / exit frame 4 and formed at both longitudinal ends of the main body 2. The abutting surfaces 3 are arranged so as to abut on the inner side surfaces 6 of the lower portions of the vertical frames 5 on both sides. In addition, the provisional width stop jig 1 for the entrance / exit frame is prepared in a plurality of types of lengths, and the one in which the distance between the contact surfaces 3 matches the opening width D of the entrance / exit frame is selected. use. Thereby, since it can support so that the space | interval of the inner side surfaces 6 of the lower part of the said vertical frame 5 may become the opening width D of an entrance / exit frame correctly, the space | interval of the vertical frame 5 of the said entrance / exit frame 4 is fixed correctly. can do. Further, since the temporary width stop jig 1 of the entrance / exit frame is formed so that the vertical thickness T of the main body 2 is thin, as shown in FIG. 3, the entrance / exit frame 4 has a door 9 attached thereto. Even so, the door 9 can be closed while the provisional width stop jig 1 for the entrance / exit frame is disposed, so that the door 9 does not get in the way and the entrance / exit frame 4 is stable. Can be fixed to the floor surface 8.
[0016]
As shown in FIG. 4, the temporary width stopping jig 1 for an entrance / exit frame according to the second embodiment of the present invention is the same as the rectangular width stopping jig 1 for an entrance / exit frame according to the first embodiment. A ridge 10 that extends in the length direction and slightly protrudes upward is formed at the center of the flat body 2 in the width direction. Thus, by forming the protrusions 10 on the main body 2, the strength of the main body 2 against bending and twisting can be improved as compared with the case where the main body 2 has a simple flat plate shape.
[0017]
Since the protrusion 10 is formed to have a thin thickness T in the vertical direction of the main body 2, it is necessary to make the upward protrusion amount small. Therefore, it is desirable to set the minimum protrusion amount necessary to ensure the strength of the main body 2. Specifically, the height of the upper end of the ridge 10 may be about 10 mm or less, more preferably about 5 mm or less from the bottom surface of the main body 2. Thus, by making the protruding amount of the ridge 10 as small as possible, the vertical thickness T of the main body 2 can be kept thin, so the door 9 is attached to the entrance / exit frame 4. Even when the door 9 is closed, the door 9 can be closed while the provisional width stop jig 1 for the entrance / exit frame is disposed. The work which fixes the entrance / exit frame 4 to the floor surface 8 can be performed.
[0018]
Further, when the ridge 10 is provided linearly so as to connect both ends of the main body 2 in the length direction, a sill is located under the ridge 10 even when the entrance / exit frame 4 has a sill. By arranging the temporary width stop jig 1 of the entrance / exit frame so as to enter, the upper part of the sill can be covered and protected, so that the sill is prevented from being damaged or soiled during construction work. Can do.
[0019]
The shape of the ridge 10 is not limited to the shape in which one relatively wide ridge 10 is provided at the center in the width direction of the main body 2 as shown in FIG. Although not shown, for example, the ridges 10 may be shifted in the width direction and provided at positions deviated in either direction, or a plurality of relatively narrow ridges 10 may be provided in parallel. . Moreover, the said protruding item | line 10 is not limited to the shape which continues in the length direction of the said main body 2, For example, as shown in FIG. The main body 2 may be arranged in the length direction.
[0020]
As shown in FIG. 6, the temporary width stopper jig 1 of the entrance / exit frame according to the third embodiment of the present invention includes the main body 2 in the temporary width stopper jig 1 of the entrance / exit frame according to the first embodiment. A notch 11 is provided in the vicinity of the central portion in the width direction at both ends in the length direction.
[0021]
Usually, in the entrance / exit frame 4 with the door 9, as shown in FIG. 7, a protruding portion 12 extending vertically is provided near the center of the inner surface 6 of the vertical frame 5 in the width direction as a contact with the door 9. There are many cases. Even in this case, the opening width D of the entrance / exit frame determined in a stepwise manner is based on the interval between the inner side surfaces 6 of the vertical frame 5 when there is no protrusion 12 of the vertical frame 5. Therefore, when the protruding portion 12 is provided in the vertical frame 5 in this way, in the temporary width stopper jig 1 of the entrance / exit frame according to the first or second embodiment, the protruding portion 12 is an obstacle. Thus, the temporary width stop jig 1 for the entrance / exit frame having a predetermined dimension prepared in advance cannot be normally disposed on the floor surface 8. As shown in FIG. 8, the notch portion 11 can be arranged such that the abutment surface 3 abuts only the inner surface 6 of the vertical frame 5, avoiding the protruding portion 12 of the vertical frame 5. It is provided to do so.
[0022]
Therefore, it is necessary that the cutout portion 11 has a size that allows the projection 12 of the vertical frame 5 that is the largest that can be expected to be fitted. Specifically, the width of the notch 11 is about 30 mm or more, more preferably about 50 mm or more, and the cutting depth is about 15 mm or more, more preferably about 25 mm or more. By providing the notch 11 as described above, even when the protruding portion 12 is provided on the inner surface 6 of the vertical frame 5 of the entrance / exit frame 4, the abutting surface 3 is avoided by avoiding the protruding portion 12. Since it is brought into contact only with the inner side surface 6 of the vertical frame 5, the temporary width stopper jig 1 of the entrance / exit frame can be arranged at a normal position, and the inner side surface of the lower side of the vertical frame 5 of the entrance / exit frame 4. It can support so that the space | interval of 6 may become the opening width D of an entrance / exit frame correctly.
[0023]
Further, as shown in FIG. 9, the temporary width stopping jig 1 of the entrance / exit frame is the temporary width stopping jig 1 of the entrance / exit frame according to the second embodiment, at both ends in the length direction of the main body 2. A notch 11 may be provided near the center in the width direction. Also in this case, the size and shape of the notch 11 are the same as those described above. Thus, even when the protrusion 12 is provided on the vertical frame 5 of the entrance / exit frame 4, the interval between the inner side surfaces 6 of the lower part of the vertical frame 5 of the entrance / exit frame 4 is accurately set to the opening of the entrance / exit frame. The width D can be supported and the strength of the main body 2 can be improved.
[0024]
【The invention's effect】
As described above, according to the provisional width stop jig for the entrance / exit frame according to claim 1 of the present invention, the distance between the contact surfaces on both sides is formed to be equal to the opening width of the entrance / exit frame. The contact surfaces are arranged so as to be in contact with the inner surfaces of the lower portions of the vertical frames on both sides so that the interval between the inner surfaces of the lower portions of the vertical frames becomes the opening width of the entrance / exit frame. Since it can support, the space | interval of the vertical frame of the said entrance / exit frame can be fixed correctly. Further, since the thickness of the main body in the vertical direction is thin, even if the doorway frame is provided with a door, the temporary width stopper jig of the doorway frame is still arranged and the door is moved. Since the door can be closed, the door does not get in the way of movement, and the work of fixing the doorway frame to the floor surface can be performed in a stable state.
[0025]
In addition to the above-described effect, the provisional width stopper jig for the entrance / exit frame according to claim 2 of the present invention is characterized in that the main body is formed with a ridge that extends in the length direction and slightly protrudes upward. Compared with the case where the main body is merely a flat plate, the strength of the main body against bending and twisting can be improved. In addition, since the thickness in the vertical direction of the main body can be reduced by reducing the protruding amount of the ridges, even if a door is attached to the entrance / exit frame, the provisional frame of the entrance / exit frame is temporary. The door can be closed with the width stop jig still in place, so that the door does not get in the way of moving and the door frame is fixed to the floor surface in a stable state. Can do. Furthermore, even when the entrance / exit frame has a sill, the upper part of the sill can be covered and protected by arranging a temporary width stop jig for the entrance / exit frame so that the sill enters under the ridge. Therefore, it is possible to prevent the threshold from being damaged or soiled during construction work.
[0026]
In addition to the above-described effect, the provisional width stopper jig for an entrance / exit frame according to claim 3 of the present invention provides the entrance / exit by providing a notch portion in the vicinity of the center portion in the width direction at both longitudinal ends of the main body. Even when a protrusion is provided on the inner surface of the vertical frame of the frame, the contact surface is contacted only with the inner surface of the vertical frame while avoiding the protrusion. The stop jig can be arranged at a normal position, and can be supported so that the interval between the inner side surfaces of the lower part of the vertical frame of the entrance / exit frame is exactly the opening width of the entrance / exit frame.
