Description

Elevator landing equipment

The present invention relates to an elevator landing device that forms a fire prevention compartment.

It is necessary to form a fire prevention zone at the elevator platform. In the elevator hall, the building wall can bear a part of the fire prevention section, but the part that is not the building wall cannot bear a part of the fire prevention section as it is. In order to make a part that is not a building wall a part of a fire prevention section, it is necessary to block a part that is not a building wall without gaps with an iron plate having a thickness of 1.5 mm or more. For example, a three-way frame provided on the landing side of the door is fixed to an opening of a building wall. However, there is a gap between the building wall and the three-way frame. Therefore, there is a conventional technique for closing this gap in order to form a fire prevention section at the elevator hall (see, for example, Patent Document 1).

In the conventional elevator landing apparatus described in Patent Document 1, a plate material having a thickness of 1.5 mm or more is used as a member for closing a gap. This board is sized to cover the entire opening of the building wall that will be the landing. In this plate material, an opening is provided at a portion corresponding to the landing door, and a three-sided frame is attached to the landing side around the opening. The operation of providing an opening in the plate material and the operation of attaching the three-way frame to the plate material are performed in a factory. The plate material that has been worked in the factory is transported to the site where the elevator is installed, and is installed at the opening of the building wall from the hoistway side so as to close the opening of the building wall. By installing the plate material at the opening of the building wall from the hoistway side, the gap between the building wall and the three-way frame is closed by the plate material. With such a series of operations, the conventional elevator hall device described in Patent Document 1 can form a fire prevention section in the elevator hall.

Japanese Patent Laid-Open No. 10-87245

However, the conventional techniques have the following problems. In the conventional elevator landing apparatus described in Patent Document 1, a three-sided frame is attached to a plate material in a factory. For this reason, the size of the plate material at the installation site or the attachment position of the three-way frame to the plate material cannot be changed, and it is difficult to cope with the construction error at the site. Further, when an excessively large plate material is used in consideration of a construction error, a load of work for installing the plate material in the opening portion increases.

The present invention has been made to solve the above-described problems, and an elevator hall device capable of forming a fire prevention zone in an elevator hall by a simple work on site in response to a construction error. Is intended to provide.

An elevator hall device according to the present invention includes a three-way frame that is disposed at an opening of a building wall provided in the elevator hall and forms a landing doorway, and a gap closing member that blocks a gap between the building wall and the three-way frame. ing. The gap closing member is held in the gap in a state where an elastic repulsion force is generated.

According to the elevator hall device according to the present invention, the gap closing member closes the gap between the building wall and the three-sided frame. The gap closing member can be held in the gap by an elastic repulsive force. The gap closing member can cope with a construction error as long as this elastic repulsion force reaches. Thereby, the elevator boarding apparatus which can form the fire prevention zone in an elevator boarding can be provided by the simple operation | work on the site corresponding to a construction error.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each figure, the same or corresponding parts are denoted by the same name, and redundant description is omitted.

Embodiment 1 FIG.
FIG. 1 is an overall view showing an elevator hall device according to Embodiment 1 of the present invention. In the elevator hall, an elevator hall device 100 is provided. The elevator hall device 100 includes a three-sided frame 1, two side closing plates 10 that are gap closing members, and one upper closing plate 20. The three-way frame 1 is disposed in the opening 2a of the building wall 2 provided in the elevator hall. The three-way frame 1 forms a landing entrance 3. The shape of the three-way frame 1 is an inverted U-shape. Inside the inverted U-shape of the three-way frame 1, a door 4 constituting the hall entrance 3 is provided.

The three-sided frame 1 is attached to the building wall 2. The three-way frame 1 has two vertical frames 31 and one upper frame 32. The two vertical frames 31 are disposed on the left side and the right side of the door 4 and extend in the vertical direction. One upper frame 32 extends between the upper ends of the left and right vertical frames 31 and extends in the horizontal direction above the door 4. The two vertical frames 31 and the upper frame 32 are installed on the landing side from the door 4 side. Each of the two vertical frames 31 has a substantially trapezoidal shape in which a metal plate is bent to form a cavity therein. The shape of the upper frame 32 is a substantially rectangular shape in which a metal plate is bent to form a cavity inside. The two vertical frames 31 and the upper frame 32 are each made of a metal plate having a thickness of 1.6 mm, for example.

One of the two side closing plates 10 is fitted in a gap 41 between the building wall 2 and the left vertical frame 31 toward the door 4. The other side closing plate 10 is fitted in a gap 41 between the building wall 2 and the right vertical frame 31 toward the door 4. The side closing plate 10 blocks the gaps 41 between the building wall 2 and the left and right vertical frames 31. Each of the side closing plates 10 is formed by bending a metal plate with the vertical direction of the gap 41 as a bending axis. The upper closing plate 20 is fitted in a gap 42 between the building wall 2 and the upper frame 32. The upper closing plate 20 closes the gap 42 between the building wall 2 and the upper frame 32. The side closing plate 10 and the upper closing plate 20 are each made of a metal plate having a thickness of 1.6 mm, for example.

FIG. 2 is a partial top view when viewed from above the three-way frame in FIG. The mounting bracket 5 is formed by joining two metal plates having an L shape. The shape of the mounting bracket 5 when the elevator hall is viewed from above is a U-shape. A surface 5 a on one end side of the mounting bracket 5 is fixed to the building wall 2. A surface 5 b on the other end side of the mounting bracket 5 is fixed to the vertical frame 31. As described above, the vertical frame 31 is attached to the building wall 2 by the mounting bracket 5. Therefore, the width of each gap 41 between the building wall 2 and the left and right vertical frames 31 is kept constant. The two metal plates forming the mounting bracket 5 are coupled by screwing. The two metal plates may be joined by welding.

The side closing plate 10 is fitted in the gap 41. The cross-sectional shape when the side closing plate 10 is cut in the horizontal direction is a V-shape. That is, the side portion closing plate 10 has a V-shaped cross section when cut along a plane perpendicular to the longitudinal direction. The side closing plate 10 is formed by bending one metal flat plate into a plate portion 10a having a length L1 and a plate portion 10b having a length L2. The plate portion 10a and the plate portion 10b are bent at the bent portion 10c. The bent portion 10 c is in contact with the vertical frame 31. An end surface 10d of the plate portion 10a opposite to the bent portion 10c is in contact with the building wall 2. The plate part 10b is in contact with the vertical frame 31 as a whole together with the bent part 10c. The length of the side closing plate 10 is set shorter than the height of the gap 41 in consideration of architectural errors. In order to close the remaining gap, an additional closing board having the same cross-sectional shape as that of the side closing board 10 and having a short length in the vertical direction of the gap 41 is prepared and partially overlapped with the side closing board 10. Push into 41. By using the additional closing plate in this way, the length direction of the gap 41 can be easily adjusted.

FIG. 3 is a cross-sectional view showing the upper part of the three-way frame of FIG. The cross-sectional shape of the upper closing plate 20 when the elevator hall is viewed from the side indicated by the arrow B is a rectangular shape. One end face 20 a of the upper closing plate 20 is welded to the upper frame 32. Thereby, the upper closing plate 20 is fixed to the upper frame 32. The upper closing plate 20 is in contact with the building wall 2 on the surface 20b opposite to the upper frame 32 side. The length L3 of the long side of the upper closing plate 20 is longer than the width of the gap 42 between the building wall 2 and the upper frame 32. Therefore, the upper closing plate 20 is inclined with respect to the upper frame 32. The angle 20c at which the upper closing plate 20 is inclined is set to be larger than the angle when the upper closing plate 20 is just in contact with both end faces of the gap 42 so that the upper closing plate 20 generates an elastic repulsive force. Note that the order of the attachment of the side closing plate 10 and the attachment of the upper closing plate 20 may be either first.

The operation of the elevator hall device according to Embodiment 1 will be described with reference to FIGS. In FIG. 2, the side closing plate 10 is a metal flat plate bent into a V shape and pushed into the gap 41 between the building wall 2 and the vertical frame 31 from the landing side. The width of the gap 41 is smaller than the width of the side closing plate 10 bent into a V shape. Therefore, in a state where the side closing plate 10 is fitted in the gap 41, the side closing plate 10 generates an elastic repulsive force that tries to return to the shape before being pushed in. The side closing plate 10 presses the building wall 2 and the vertical frame 31 respectively. The side closing plate 10 is held in the gap 41 by the elastic repulsive force of the side closing plate 10. As a result, the side closing plate 10 can close the gap 41.

Further, the side closing plate 10 is held in the gap 41 between the building wall 2 and the vertical frame 31 by an elastic repulsive force. Therefore, even when a vibration due to an earthquake or the like occurs, the side closing plate 10 can absorb the shock of the vibration and is not easily broken. Further, the side closing plate 10 has a shape that can be easily inserted into the gap 41 by using the bent portion 10c as a tip.

Also, the width of the side closing plate 10 before being inserted into the gap 41 is made wider than the maximum width of the gap 41 that is considered due to construction errors. Therefore, the side closing plate 10 can close the gap 41 while corresponding to a construction error at the site.

Further, the vertical frame 31 is fixed to the building wall 2 by the mounting bracket 5. Therefore, even when the side closing plate 10 is inserted, the position of the vertical frame 31 does not shift.

3, when the upper closing plate 20 is welded to the upper frame 32, the upper closing plate 20 is welded to the upper frame 32 while being pressed against the building wall 2 side. In this case, the length L3 of the upper closing plate 20 is longer than the width of the gap 42. The upper closing plate 20 generates an elastic repulsive force. Therefore, the upper closing plate 20 presses the building wall 2. As a result, the upper closing plate 20 closes the gap 42. When the cross-sectional shape of the upper closing plate 20 is the same V shape or U shape as that of the side closing plate 10, the upper closing plate 20 will be side closed if the upper closing plate 10 is not sufficiently pushed into the gap 42. There is a possibility that a gap is generated at a location where the plate 10 comes into contact. Therefore, the gap between the upper closing plate 20 and the side closing plate 10 can be made difficult to occur by closing with a rectangular flat plate.

As described above, the side closing plate 10 and the upper closing plate 20 according to the first embodiment can provide an elevator landing device that forms a fire prevention section that can cope with a construction error on the site by a simple method. it can.

Moreover, the cross-sectional shape of the side closing plate 10 is V-shaped. Therefore, the side closing plate 10 is easily inserted into the gap 41 between the building wall 2 and the vertical frame 31. In addition, even when a vibration due to an earthquake or the like occurs, the side closing plate 10 has an elastic repulsive force and thus is less likely to be broken by the shock of the vibration.

Further, the gap 41 between the building wall 2 and the vertical frame 31 is closed by the side closing plate 10. After the gap 41 is closed, the landing side of the gap 41 is covered with a decorative board. Therefore, the side closing plate 10 cannot be seen from the landing side. Similarly, the gap 42 between the building wall 2 and the upper frame 32 is closed by the upper closing plate 20. After the gap 42 is closed, the landing side of the gap 42 is covered with a decorative board. Therefore, the upper closing plate 20 cannot be seen from the landing side. Thus, the side closing plate 10 and the upper closing plate 20 do not affect the design.

Embodiment 2. FIG.
Next, the elevator boarding apparatus in Embodiment 2 is demonstrated using FIG. Compared to the first embodiment, in the second embodiment, the sectional shape of the side closing plate is different.

FIG. 4 is a partial top view when viewed from above the three-way frame in the elevator hall device according to Embodiment 2 of the present invention. In the gap 41 between the building wall 2 and the vertical frame 31, the side closing plate 11 is fitted. The cross-sectional shape obtained by cutting the side closing plate 11 in the horizontal direction is a J-shape. That is, the side portion closing plate 11 has a J-shaped cross section when cut along a plane perpendicular to the longitudinal direction. A short surface 11 a of the side closing plate 11 is in contact with the building wall 2. The long side surface 11 b of the side closing plate 11 is in contact with the vertical frame 31. The side closing plate 11 is made by bending a metal flat plate having a thickness of, for example, 1.6 mm. Accordingly, the side closing plate 11 has an elastic repulsive force in the direction in which the J-shape opens.

The side closing plate 11 is bent into a J shape and then pushed into the gap 41 from the landing side. The side closing plate 11 generates an elastic repulsive force in a direction in which the side blocking plate 11 is pressed against the building wall 2 and the vertical frame 31. Therefore, the side closing plate 11 is held in the gap 41 in a state where an elastic repulsive force is generated. Moreover, the side part closing board 11 is pressing with respect to not only the vertical frame 31 but the building wall 2 by the surface. Therefore, the side closing plate 11 is held in the gap 41 more strongly than in the case of the first embodiment.

Thus, the side closing plate 11 of the second embodiment is bent into a J shape and has an elastic repulsive force in the direction in which the J shape opens. Thereby, the side part closing board 11 is still stronger, and is hold | maintained in the clearance gap 41 of the building wall 2 and the vertical frame 31. FIG. In addition, the cross-sectional shape of the side part closing board 11 can also be made into a U shape by extending the surface 11a of the short side of J shape. In this case, since the extended side of the side closing plate 11 is in contact with the building wall 2 on the surface, the side closing plate 11 can give a stronger elastic repulsive force to the building wall 2. Therefore, the side closing plate 11 is stronger and is held in the gap 41 between the building wall 2 and the vertical frame 31.

Embodiment 3 FIG.
Next, the elevator hall apparatus in Embodiment 3 is demonstrated using FIG. In the third embodiment, the side closing plate is composed of two plate members.

FIG. 5 is a partial top view when viewed from above the three-way frame in the elevator hall device according to Embodiment 3 of the present invention. A side closing plate 12 is fitted in a gap 41 between the building wall 2 and the vertical frame 31. The cross-sectional shape obtained by cutting the side closing plate 12 in the horizontal direction is a V-shape. That is, the cross-sectional shape of the side closing plate 12 when cut along a plane perpendicular to the longitudinal direction has a V shape. The side closing plate 12 is formed by welding two

plate members

121 and 122. The plate member 121 and the plate member 122 are welded at the joint 12a. The plate member 121 and the plate member 122 are metal flat plates each having a thickness of, for example, 1.6 mm. The plate member 121 is entirely in contact with the vertical frame 31 together with the joint 12a. The plate member 122 is in contact with the building wall 2 at the end surface 12b opposite to the joint 12a.

The plate member 121 and the plate member 122 which are welded are pushed into the gap 41 from the hoistway side as the side block 12. The plate member 121 and the plate member 122 before being pushed into the gap 41 are joined so as to have an angle larger than the angle 12c when pushed. Therefore, the side closing plate 12 is compressed in a direction in which the angle formed by the plate member 121 and the plate member 122 becomes smaller and is pushed into the gap 41. Accordingly, an elastic repulsion force is generated on the side closing plate 12 to return to the original angle. Therefore, the side closing plate 12 is pushed in while pressing each of the building wall 2 and the vertical frame 31. The side closing plate 12 is held in the gap 41 when it is pushed into the gap 41 by the elastic repulsive force of the side closing plate 12. Accordingly, the side closing plate 12 can close the gap 41. Note that the side closing plate 12 is fitted from the landing side. However, the side closing plate 12 may be fitted from the hoistway side.

Also, the plate member 121 and the plate member 122 are carried to the site in a state where they are not joined. Thereafter, the plate member 121 and the plate member 122 are joined to the side closing plate 12 at the site. Therefore, even when a plate member having a short length in the width direction of the gap 41 is used, the side closing plate 12 can be configured. Further, in addition to the plate member 121 and the plate member 122, a third plate member can be additionally joined and joined in a Z-shape. Further, when the width of the gap 41 is different from the design, the closing width can be easily adjusted by changing the angle at which the plate member 121 and the plate member 122 are joined.

As described above, according to the side closing plate 12 of the third embodiment, the gap 41 can be closed by welding two plate members, so the length in the width direction of the gap is shorter than the width of the gap 41. The side closing plate can be configured using a plate member. Moreover, the angle which joins two board members can also be adjusted easily. Thereby, it can respond to the construction error on the spot by a simple method.
