Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-way frame installed and fixed at an entrance of an elevator hall.

[0002]

2. Description of the Related Art In a building such as a building where an elevator is installed, an opening serving as an entrance / exit of a landing is provided on a wall surface facing a hoistway of each floor. Then, in the opening, a three-way frame 100 as shown in FIG. 12, for example, is installed and fixed together with a hall opening / closing door and its threshold.

This three-way frame 100 is a pair of left and right vertical frames 10.
1 and an upper frame 102 that connects the pair of vertical frames 101 on the upper end side thereof. These pair of vertical frames 101
The upper frame 102 is usually formed by bending a metal plate material such as a stainless steel plate into an appropriate shape according to the structure near the entrance / exit of the hall, the design of the hall, and the like. As a specific example, the pair of left and right vertical frames 101 has a decorative surface having a substantially U-shaped cross section, for example, as shown in FIG. 13, and bending pieces are provided at both ends of the decorative surface. Formed into a shape. Then, reinforcing members 103 for increasing the strength of the vertical frame 101 and suppressing the displacement of the three-way frame 100 at the time of installation or after installation are attached between the bent pieces provided at both ends of the decorative surface. ing.

As the reinforcing member 103, a long metal material called a flat bar having a predetermined width and thickness is conventionally cut into a length corresponding to the distance between the bent pieces of the vertical frame 101. Was used. The reinforcing members 103 are arranged at predetermined intervals in the lengthwise direction of the vertical frame 101 so that sufficient reinforcing strength can be obtained, and both ends thereof are welded to the bent pieces of the vertical frame 101, so that Frame 1
It was attached to 01.

[0005]

By the way, in the three-way frame 100 of the elevator hall as described above, the shapes of the vertical frame 101 and the upper frame 102 are determined according to the structure near the entrance / exit of the hall, the design of the hall, and the like. For example, the inclination angle and the depth dimension of the decorative surface may be different for each hall or each building. Further, the distance between the bent pieces provided at both ends of the decorative surface is also different accordingly.

For this reason, in the conventional three-sided frame 100, when the shapes of the vertical frame 101 and the upper frame 102 are determined, the reinforcing member 103 corresponding to them is produced and the vertical frame 101 and the upper frame 10 are manufactured.
It is necessary to attach it to the two, this is the three-way frame 100
It was a big obstacle in shortening the construction period. That is, in the conventional three-sided frame 100, the shapes of the vertical frame 101 and the upper frame 102 are determined, the number and size of the reinforcing members 103 are clarified, and the necessary materials are ordered, produced, and attached accordingly. Therefore, it was difficult to reduce the construction period.

In order to reduce the manufacturing cost of the three-sided frame 100, it is very effective to make the reinforcing member 103 in advance by using, for example, a scrap material, but in the conventional three-sided frame 100, The reinforcing member 103 is attached to the vertical frame 101 and the upper frame 10.
Since it needs to be manufactured in conformity with the shape of No. 2, it cannot be manufactured in advance and there is a problem that it is difficult to reduce the manufacturing cost.

Further, if a dimensional error or the like occurs when manufacturing the vertical frame 101 or the upper frame 102, the size of the reinforcing member 103 does not match the vertical frame 101 or the upper frame 102, and the reinforcing member 103 is manufactured again. There may be a need.

Further, for example, as shown in FIG. 14, a vertical frame 1
When 01 is a special shape, if a flat plate-shaped reinforcing member 103 is used as in the conventional example, the reinforcing member 103 may interfere with a part of the vertical frame 101, so that the reinforcing member 103 is appropriate. There was a case where it was necessary to fold it at a large portion to avoid interference. Therefore, there is also a problem that sufficient strength cannot be obtained as the reinforcing strength by the reinforcing member 103.

The present invention was devised in view of the above conventional circumstances, and has a structure in which the reinforcing member can be shared even when the shapes of the vertical frame and the upper frame are different from each other, thereby shortening the construction period and manufacturing cost. It is an object of the present invention to provide a three-sided frame for an elevator hall in which the reinforcement member can absorb the dimensional error of the vertical frame and the upper frame and can obtain sufficient reinforcing strength.

[0011]

The present invention has a pair of left and right vertical frames and an upper frame connecting these vertical frames, and at least a part of the vertical frame or the upper frame is reinforced by a reinforcing member. In the three-sided frame that is installed and fixed at the entrance of the elevator hall, at both ends in the width direction of the vertical frame or the upper frame,
Mounting pieces for mounting the reinforcing member are respectively provided upright, and the reinforcing member has a substantially L-shape having a rising piece fixed to one mounting piece of the vertical frame or the upper frame at one end side. And a substantially L-shaped second member having a rising piece fixed to the other mounting piece of the vertical frame or the upper frame on one end side thereof. The second member and the second member are connected to each other in such a manner that the other end sides of the two members are overlapped with each other such that the distance between the respective rising pieces is substantially equal to the inner diameter dimension between the mounting pieces of the vertical frame or the upper frame. And is attached to the vertical frame or the upper frame.

In the three-way frame of the elevator hall according to the present invention, the reinforcing member connects the other end sides of the first member and the second member by superposing them on each other and changing the length of the superposed portion. Since the size of the entire reinforcing member can be adjusted, the reinforcing member can be shared between the vertical frames or the upper frames having different shapes, and the dimensional error of the vertical frame or the upper frame has occurred. Even in this case, the dimensional error can be absorbed by the reinforcing member, and the reinforcing member can be properly attached. Furthermore, by adjusting the position at which the rising piece of the reinforcing member is fixed to the mounting piece of the vertical frame or the upper frame, the reinforcing member can be mounted without interfering with the reinforcing member with respect to the vertical frame or the upper frame. It can be done properly.

One of the pair of vertical frames 2 forming the three-way frame 1 is shown in an enlarged manner in FIG. The vertical frame 2 has both ends in the width direction bent into a Z shape, so that the both ends of the vertical frame 2 are attached with attachment pieces 5a for attaching a reinforcing member 10 described later.
Each of the 5b has an upright shape. These attachment pieces 5a, 5b are provided substantially parallel to each other at both ends in the width direction of the vertical frame 2 so as to face each other with a predetermined inner diameter dimension L depending on the thickness of the building wall surface and the like. In addition, through holes (not shown) through which the bolts 6 for attaching the reinforcing member 10 are inserted are provided at a predetermined pitch along the length direction of the attachment pieces 5a and 5b. Then, in the vertical frame 2, the mounting pieces 5a and 5b are provided at the places where the through holes are provided.

The reinforcing member 10 improves the strength of the vertical frame 2 and suppresses displacement of the vertical frame 2 during or after installation. Although only one of the pair of vertical frames 2 is shown in FIG. 2, the other vertical frame has the same shape as this one vertical frame.

As shown in FIGS. 3 and 4, the reinforcing member 10 has a first member 11 and a second member 12 formed by bending an elongated metal plate material into a substantially L shape. The first member 11 and the second member 12 are combined and configured.

The first member 11 has, on one end side thereof, a rising piece 11 fixed to the one mounting piece 5a of the vertical frame 2 described above.

The rising piece 11a is provided with a through hole 13 which is in communication with the through hole provided in the one mounting piece 5a of the vertical frame 2 and into which the bolt 6 for attaching the reinforcing member 10 is inserted. Further, a long hole 14 having a predetermined length M is formed along the length direction of the other end side of the first member 11 which is substantially perpendicular to the rising piece 11a.

The second member 12 has, on one end side thereof, a rising piece 12 fixed to the other mounting piece 5b of the vertical frame 2 described above.
a. Further, the rising piece 12a is provided with a through hole 15 which communicates with a through hole formed in the other mounting piece 5b of the vertical frame 2 and into which the bolt 6 for attaching the reinforcing member 10 is inserted. Further, a through hole 16 having a shape corresponding to the shaft portion of the fastening bolt 17 is formed on the other end side of the second member 12 which is substantially perpendicular to the rising piece 12a.

The reinforcing member 10 is composed of the first member 11
Of the second member 12 and the other end of the second member 12 in which the through hole 16 is formed are overlapped in the thickness direction, and the first member 11 and the second member 12 are , First
Slot 14 of member 11 and through hole 16 of second member 12
The reinforcing bolt 1 and the nut 18 which are respectively inserted into the
It is set to 0. At this time, the first member 11 and the second member 1
2 is the distance between the respective startup pieces 11a and 12a,
That is, the size S of the entire reinforcing member 10 is connected in a state in which the mutual positional relationship is adjusted so that the size S of the reinforcing member 10 substantially matches the inner diameter dimension L between the mounting pieces 5a and 5b of the vertical frame 2.

More specifically, the reinforcing member 10 is fastened so that the first member 11 and the second member 12 are inserted into the elongated hole 14 and the through hole 16 in a state where the other ends thereof are overlapped with each other. Since the bolt 17 and the nut 18 are connected to each other and integrated, the relative position between the first member 11 and the second member 12 is changed to adjust the length of the overlapping portion. By doing so, the size S of the entire reinforcing member 10 can be adjusted within the range of the length M of the elongated hole 14. That is, this reinforcing member 10
As shown in FIG. 5A, the length of the overlapping portion of the other end side of the first member 11 and the other end side of the second member 12 is maximized, and the shaft portion of the fastening bolt 17 is formed into a long hole. When the first member 11 and the second member 12 are connected to each other by being positioned at one end of 14, the overall size S becomes the minimum. On the other hand, FIG.
As shown in (b), the length of the overlapping portion of the other end side of the first member 11 and the other end side of the second member 12 is minimized, and the shaft portion of the fastening bolt 17 is set to the long hole 14. When the first member 11 and the second member 12 are connected to each other by being positioned at the other end, the overall size S becomes maximum. And the reinforcement member 10 can adjust the whole size S between these.

In the three-way frame 1 to which the present invention is applied, the reinforcing member 10 is structured as described above, and the overall size S thereof is substantially the same as the inner diameter dimension L between the mounting pieces 5a and 5b of the vertical frame 2 described above. Bolt 6 and nut 7 after adjusting so that
The vertical frame 2 is mounted between the mounting pieces 5a and 5b. Therefore, the vertical frame 2 (or the vertical frame 3) may be selected depending on the structure near the entrance / exit of the hall or the design of the hall.
Even when the inner diameter dimension L between the mounting pieces 5a and 5b is different for each case, the reinforcing member 10 can be shared between the vertical frames 2 having different inner diameter dimensions L between the mounting pieces 5a and 5b.

Specifically, for example, as shown in FIG. 6A, when the inner diameter dimension L between the mounting pieces 5a and 5b of the vertical frame 2 is relatively narrow, the reinforcing member 10 is the first member. 11 and 2
The overlapping length with the member 12 of the vertical frame 2 is increased, and the overall size S is set to be small according to the inner diameter dimension L between the mounting pieces 5a and 5b of the vertical frame 2, and between the mounting pieces 5a and 5b of the vertical frame 2. Attached to. On the other hand, for example, as shown in FIG. 6B, when the inner diameter dimension L between the mounting pieces 5a and 5b of the vertical frame 2 is comparatively wide, the reinforcing member 10 includes the first member 11 and the second member.
The overlapping length with the member 12 of the vertical frame 2 is made small, and the overall size S is set to be large in accordance with the inner diameter dimension L between the mounting pieces 5a, 5b of the vertical frame 2, and between the mounting pieces 5a, 5b of the vertical frame 2. Attached to.

As described above, the three-sided frame 1 to which the present invention is applied
Then, the size S of the entire reinforcing member 10 is set to the mounting piece 5 of the vertical frame 2.
Since it can be adjusted according to the inner diameter dimension L between a and 5b, the reinforcing member 1 common to the vertical frames 2 of various shapes is used.
0 can be used. Therefore, regardless of the shape of the vertical frame 2, a large amount of the reinforcing member 10 can be manufactured at one time, and the work period and the manufacturing cost can be reduced. In particular, since the reinforcing member 10 can be manufactured by using a scrap material or the like, and the reinforcing member 10 can be manufactured and stored in advance, it is possible to significantly reduce the manufacturing cost.

Even if the inner diameter L between the mounting pieces 5a and 5b of the vertical frame 2 is different from the design dimension due to a dimensional error during manufacturing, this dimensional error can be adjusted by adjusting the size S of the entire reinforcing member 10. Can be absorbed, and the reinforcement member 10 can be properly attached without re-manufacturing the reinforcement member 10.

Further, in the three-way frame 1 to which the present invention is applied, the reinforcing member 10 is composed of the combination of the first member 11 and the second member 12, so that the first member 1
1 and the second member 12 are combined, that is, the first
Both members 1 when connecting the member 11 and the second member 12 of
By changing the directions of 1 and 12, the shape of the reinforcing member 10 can be adjusted according to the positions of the mounting pieces 5a and 5b of the vertical frame 2.

Specifically, in the example shown in FIGS. 6 (a) and 6 (b), the vertical frame 2 has a mounting piece 5b rather than a mounting piece 5a.
Has a shape that is positioned on the outer side (the wall side on which the vertical frame 2 is installed), and accordingly, the start-up piece 11a of the first member 11 fixed to the mounting piece 5a is the inner side (vertical side). The first member 11 and the second member 12 are arranged such that the rising piece 12a of the second member 12 that is projected to the frame 2 side) and fixed to the mounting piece 5b projects to the outside (wall side). Although the reinforcing member 10 is configured by combining them, for example, as shown in FIG.
When the vertical frame 2 has a shape in which the mounting piece 5a is located on the outer side (wall side), as shown in FIG.
The first member 11 and the second member 11 are arranged so that 1a projects outward (wall side) and the rising piece 12a projects inward (vertical frame 2 side).
The reinforcing member 10 may be configured by combining the member 12 of FIG. Further, as shown in FIG. 8, for example, when the mounting piece 5a and the mounting piece 5b of the vertical frame 2 are shaped so that the distances from the wall are substantially equal to each other, the rising piece 11a and the standing piece 11a. The reinforcing member 10 may be configured by combining the first member 11 and the second member 12 so that the lifting pieces 12a project in the same direction.

Further, in the three-way frame 1 to which the present invention is applied, both end portions in the width direction of the vertical frame 2 are bent into a Z shape to provide mounting pieces 5a and 5b, and the mounting pieces 5a and 5b are provided with a reinforcing member. Since the rising pieces 11a of the first member 11 and the rising pieces 12a of the second member 12 that form the device 10 are fixed to each other, for example, as shown in FIG. Even if it has a special shape protruding toward the wall in the middle part, the reinforcing member 10 can be properly attached to the vertical frame 2 without interfering with the protruding part of the vertical frame 2. Therefore, it is not necessary to take a measure such as bending the reinforcing member 10 in the middle thereof to avoid interference with the vertical frame 2, and it is possible to prevent a decrease in reinforcing strength, which is a problem when the reinforcing member 10 is bent in the middle, and It is possible to secure sufficient reinforcement strength.

In the above description, both ends of the vertical frame 2 in the width direction are bent into a Z shape, and the attachment pieces 5a and 5b for attaching the reinforcing member 10 are directed toward the wall side on which the vertical frame 2 is installed. In the three-way frame 1 to which the present invention is applied, as shown in FIG. 10, both end portions in the width direction of the vertical frame 2 are bent into a U-shape for reinforcement. Mounting pieces 5a, 5b for mounting the member 10
May be provided so as to project to the vertical frame 2 side. In this case, a sufficient working space is secured between the vertical frame 2 and the wall on which the vertical frame 2 is installed, and the workability of installing the vertical frame 2 can be improved. .

Further, in the three-way frame 1 to which the present invention is applied, as shown in FIG. 11, the first member 11 and the second member 12 constituting the reinforcing member 10 are fastened with the fastening bolt 17 and the nut 1.
When connecting using the first member 11 and the second member 11,
Along with the member 12 described above, the fixing metal fitting 20 for installing and fixing the vertical frame 2 on the wall may be fastened together. In this way, when connecting the first member 11 and the second member 12, the fixing metal fitting 20 is fixed to the fastening bolt 17 and the nut 18.
If they are fastened together, the work of attaching the fixing metal fitting 20 to the vertical frame 2 in a separate process becomes unnecessary, and the workability can be further improved.

Although the example of attaching the reinforcing member 10 to the vertical frame 2 has been described above, in the three-way frame 1 to which the present invention is applied, the reinforcing member 10 may be attached to the upper frame 3 as well. . In this case, similarly to the vertical frame 2, the upper frame 3
