Description

  The present invention relates to a hoistway structure of an elevator apparatus used in a general house or a collective house.

  Conventionally, elevator devices have been used in various places, and in particular, in recent years, installation has been progressing in resident houses that have not been installed so far, with the aging of residents.

  However, the elevator system has a burden on the building frame caused by a mechanism that raises and lowers the elevator car, for example, a horizontal load transmitted to the building frame by the elevator unit. It was needed for side construction. For this reason, although it is desired to install an elevator device, it has been difficult to increase the cost burden at the time of new construction and to install additional equipment at the time of building renovation.

  Therefore, for example, the hoistway where the elevator car ascends and descends is made independent of the building enclosure so as not to put a burden on the building enclosure (for example, Patent Document 1), but the strength of the hoistway itself is required. This led to an increase in the price of the entire elevator system.

  Therefore, there has been a demand for an elevator apparatus that can reduce the burden on the building frame while simplifying the structure of the hoistway itself so as to suppress the increase in the price of installing the elevator apparatus.

In addition, since an elevator device is installed in a general house, the living space is reduced by that amount. Therefore, there is a demand for a method for reducing the installation space, that is, the installation area of the hoistway as much as possible.

  The present invention was invented in view of the above-mentioned background art, and the problem was that the reinforcement work on the building frame side accompanying the installation of the elevator device was made easier than before while suppressing the hoistway installation area. The present invention is to provide a hoistway structure for an elevator apparatus.

  In order to solve the above-described problem, in the present invention according to claim 1, a space communicating in the vertical direction provided in a part of the building frame, which is formed in a substantially U shape at predetermined intervals in the vertical direction of the space. Elevator elevator having a hoistway main body having a horizontal beam portion of the building frame and a hoistway formed by providing a guide rail wall unit at the U-shaped open portion of the horizontal beam portion so as to close the open portion. In the road structure, the guide rail wall unit has a vertical beam material extending along the vertical direction on the inner surface of the hoistway along the vertical direction, and the vertical beam material at the U-shaped tip portion of the hoistway body. The elevator apparatus has a hoistway structure characterized by being provided so as to be carried.

  In addition to the above, the present invention according to claim 2 is characterized in that the longitudinal beam member is brought into contact with the tip of the transverse beam portion and is erected on a plurality of transverse beam portions.

  Further, in the present invention according to claim 3, in addition to the above, the guide rail wall unit is characterized in that a thin wall is held on the surface facing the hoistway outside of the vertical beam member.

  In the hoistway structure of the elevator apparatus according to the first aspect of the present invention, the load of the elevator apparatus is provided on the cross beam of the building frame via the guide rail of the guide rail wall unit, so that the It is possible to support the load of the elevator apparatus with a certain beam beam part that is not particularly reinforced for hoistway, and in the guide rail wall unit, the guide rail is provided on the side surface of the vertical beam material, The guide rail is contained within the thickness of the wall unit, and an increase in the installation area of the hoistway more than necessary can be suppressed.

  In the hoistway structure of the elevator apparatus according to the second aspect of the present invention, the vertical beam member is further brought into contact with the front end surface of the horizontal beam portion and is erected on the plurality of horizontal beam portions, thereby more effectively applying the horizontal load. It becomes possible to support.

  In the hoistway structure of the elevator apparatus according to the third aspect of the present invention, the hoistway structure of the hoistway outer surface can be immediately finished when the hoistway is formed by further having a thin wall. Become.

  The best mode of the present invention will be described in the following embodiments shown in FIGS. 1 and 2 are horizontal cross sections of the hoistway, FIG. 1 is a cross section including the opening for forming the landing, and FIG. 2 is a cross section including the boundary portion of each floor, that is, the building frame structure (horizontal beam portion). is there.

  In this embodiment, it is a space that is provided in a part of a building frame and communicates in the vertical direction, and has a horizontal beam portion 14 of the building frame that is formed in a substantially U shape at predetermined intervals in the vertical direction of the space. In the hoistway structure of the elevator apparatus 1, which has a hoistway 4 configured to be provided with a guide rail wall unit 3 at the U-shaped open portion of the road main body 2 and the transverse beam portion 14 so as to close the open portion, The wall unit 3 has a vertical beam member 6 along the vertical direction for holding the guide rail 5 along the inner surface of the hoistway 4 along the vertical direction, and the vertical beam member 6 at the U-shaped tip portion of the hoistway body 2. Is provided. The guide rail wall unit 3 holds a thin wall 8 on the outward facing surface of the hoistway 4 of the vertical beam member 6.

  Although the wall portion constituting the hoistway body 2 is shown in the figure as a solid wall structure filled with the interior, it is not limited to this, and is a so-called existing structure composed of columns, studs, trunk edges, and the like. It may be of the construction method. Rather, it is possible to use even a building structure having such a wall structure, and accordingly, it is possible to suppress an increase in the cost of the building structure.

  And the guide rail wall unit 3 which obstruct | occludes the open part of the hoistway main body 2 has the guide rail 5 in the inner surface of the hoistway 4, and the guide rail 5 is formed continuously in the up-down direction of the hoistway. Therefore, it is impossible to form a frame by providing a material to be connected between the opposing surfaces of the respective vertical beam members 6. Therefore, for example, a crosspiece such as a horizontal trunk edge fixed to the outward facing surface of the hoistway 4 of the vertical beam member 6 is used or not, and the face material is similarly directed to the outer side of the hoistway 4 of the vertical beam member 6. It may be fixed to the surface. In this embodiment, only the thin wall 8 is used as the face material, but a combination thereof may be used. The thin wall 8 may be made of a commonly used face material such as a plaster board or plywood.

  In this embodiment, the guide rail wall unit 3 is fixed to the cross beam portion 14 of the building frame by providing a fixture 7 having an L-shaped cross section at a portion corresponding to the cross beam portion 14 of the vertical beam member 6. The surfaces corresponding to the side surfaces and the distal ends of the cross beam portions 14 are fixed in contact with each other. By doing in this way, it will receive a required load in the cross beam part 14, it is not necessary to receive in the whole upper and lower surfaces including the cross beam part 14 front-end | tip of the hoistway main body 2, and it is for installation in a required position suitably. An opening 13 can be formed. Of course, the fixture 7 may be provided intermittently at a position corresponding to the cross beam portion 14, or may be continuously formed and integrated. In addition, when it integrates, it is effective also in reinforcement of the longitudinal beam material 6. FIG.

  The guide rail wall unit 3 is formed with a height so as to extend over each floor or across multiple floors, but in any case, forming the guide rail wall unit 3 having a height extending over the entire length in the vertical direction is not possible. Since it is not realistic, a plurality of guide rail wall units 3 are connected. Therefore, the longitudinal beam members 6 are connected to each other, and the guide rail wall unit 3 is connected. Note that this connecting function may be added to the fixture 7 and integrated.

  As described above, the guide rail wall unit 3 fixes the guide rail 5 along the side surface of the vertical beam member 6 so that the guide rail 5 faces and is used. The vertical beam member 6 can be made of various materials and structures such as wooden and iron, and does not have to be in the form of a square member as shown. In this embodiment, the wooden structural pillar square material used by the conventional construction method etc. is used. If a portion for fixing the guide rail 5 to the vertical beam member 6 is provided at a portion where the fixing tool 7 is used, the load load of the elevator car 12 and the like applied via the guide rail 5 can be efficiently transmitted to the horizontal beam portion 14. As a whole, these overloads are maintained, so that the reinforcement of the longitudinal beam can be minimized.

  A rod portion of the jack 9 (only the rod portion is shown in the figure) is disposed between the guide rails 5 and is connected to a platform for placing an elevator car 12 connected to the rod. The platform is connected to a rod of the jack 9 and further engaged with the platform vertical frame 10 that engages with the guide rail 5, and a platform horizontal frame 11 that protrudes horizontally from the platform vertical frame 10 and on which the elevator car 12 is placed. Become. 1 and 2, the platform and the elevator car 12 are omitted by dotted lines. Door devices are provided at the entrance / exit of the elevator car 12 and the opening 13 for landing installation. Various door devices, such as sliding doors and hinged doors, can be used, and those that are linked to the elevator car side and the landing side can be used.

  As described above, the present embodiment has been described with reference to FIGS. 1 and 2. In particular, in FIG. 1A, the guide rail wall unit 3 is once formed and drawn in the form of being integrally installed in the hoistway body 2. However, it is also included in the scope of the present invention that the hoistway body 2 is separately provided with the longitudinal beam member 6 and the like to form the structure of FIG. 1B and FIG. Further, the vertical beam member 6, the horizontal beam portion 14 and the like are not reinforced at all, but may be appropriately reinforced if necessary.

  Next, another embodiment of the present invention will be described in another embodiment shown in FIG. Note that a description of the same parts as in the above embodiment is omitted.

  In the present embodiment, the portion that has been held on the cross beam portion 14 via the fixture 7 in the above embodiment, the vertical beam member 6 itself is brought into contact with the tip of the cross beam portion 14 and is installed on the plurality of cross beam portions 14. ing. By doing in this way, it differs in using the whole vertical beam material 6 as the fixing tool 7 in the said embodiment. In this case, the horizontal width of the platform vertical frame 10 can be increased because the distance between the guide rails 5 is increased. As a result, it is possible to contribute to the improvement of running stability during elevation.

  If the size of the hoistway main body 2 is the same as that of the above embodiment, the guide rail wall unit 3 is increased. Therefore, for example, if the hoistway main body 2 is made smaller, the hoistway space same as that of the above embodiment is used. It can be.
