Description

  The present invention relates to an elevator structure in a wooden building.

Conventionally, when an elevator is installed in an RC structure or an S structure, a guide rail is fixed to an RC housing wall inside the elevator hoistway through bracket hardware (see, for example, Patent Document 1).
On the other hand, when installing an elevator in a wooden building, a steel frame F as shown in FIG. 8 is installed in the elevator hoistway in order to separate the wooden frame from the elevator device and suppress transmission of load and vibration. The guide rail and the driving device are fixed to the steel frame F.

JP 2011-153017 A

  However, in such a structure, the construction cost of the steel frame is incurred separately from the elevator work during construction of the wooden building, and the production period of the steel frame and the preceding construction period of the steel frame in the building construction process It was necessary to consider. Furthermore, it was necessary to allow a space for installing the steel frame in the elevator hoistway.

  The present invention has been made in view of the above-described problems, and it is an object of the present invention to provide an elevator structure capable of reducing the construction cost and the construction period while improving the efficiency of the elevator installation space in a wooden building. And

  The present invention for solving such problems includes a wooden frame having an elevator hoistway, a reinforced concrete foundation installed at a lower portion of the wooden frame, and whether the elevator is disposed in the elevator hoistway, A drive mechanism that raises and lowers the car; a rope that interlocks the car and the drive mechanism; a guide rail that is erected on the foundation and regulates a horizontal position of the car; and And a bracket to be fixed to the housing. The foundation supports the load of the car via the guide rail and supports the load of the drive mechanism.

  According to such a configuration, the guide rail is fixed to the wooden frame by the bracket, the foundation supports the load of the car via the guide rail, and the foundation supports the load of the drive mechanism. Therefore, since it is not necessary to install a steel frame in the elevator hoistway, the construction cost of the steel frame can be reduced, and it is not necessary to consider the production period of the steel frame and the preceding construction period. Since it is not necessary to allow a space for installing the steel frame in the elevator hoistway, the efficiency of the elevator installation space can be improved. In addition, since a steel frame is not required and the communication part of the elevator hoistway can be brought closer to the car than before, it is possible to use a normal three-way frame without requiring a special three-way frame for the elevator platform. Therefore, the construction cost and the construction period can be reduced.

  The bracket may be configured to be deformable so as to absorb a relative displacement between the wooden frame and the guide rail.

  According to such a configuration, the bracket can be deformed to absorb the relative displacement between the wooden frame and the guide rail. Therefore, even if the wooden frame shrinks or deforms due to drying or the like, the guide rail is displaced or distorted. Can be prevented.

  Further, in the case where the bracket includes a fixing portion that is fixed to the wooden casing, and an extension portion that extends from the fixing portion into the elevator hoistway, the extension portion has a thickness direction. It is good to be comprised in the thin plate shape extended in a horizontal direction as an up-down direction.

  According to such a configuration, since the extending portion of the bracket is configured in a thin plate shape extending in the horizontal direction with the plate thickness direction being the vertical direction, the wooden frame is contracted and deformed by drying or the like. In addition, it is possible to cope with the thin plate-like extension of the bracket in the vertical direction according to the relative displacement, and it is possible to prevent the guide rail from being displaced or distorted.

  Further, in the case where the bracket includes a fixing portion that is fixed to the wooden casing, and an extension portion that extends from the fixing portion into the elevator hoistway, the extension portion has a vertical cross-section. It is good that it is configured in an L shape in view.

  According to such a configuration, since the extension part of the bracket is configured in an L shape in a cross-sectional view in the vertical direction, the extension part of the bracket even if the wooden frame shrinks or deforms due to drying or the like. By changing the angle of the bent portion of the L-shape, relative displacement can be absorbed, and the guide rail can be prevented from being displaced or distorted. In addition, the distance between the guide rail and the wall surface in the elevator hoistway can be kept constant by changing the angle of the boundary portion between the fixed portion and the extending portion.

  The extending portion includes a vertical portion extending in a vertical direction from the fixed portion, a horizontal extending portion extending in a horizontal direction from one end of the vertical portion, and the horizontal extending portion fixed to the vertical portion. It is good to provide the support piece which supports a part.

  According to such a configuration, since the extension portion of the bracket includes the support piece that is fixed to the vertical portion and supports the horizontal extension portion, for example, when the elevator apparatus is installed, the extension portion of the elevator hoistway is provided. A temporary beam for lifting can be supported at the upper part.

  Moreover, the said fixing | fixed part is good to be formed in groove shape by the cross sectional view, and is good to be fitted by the horizontal member of the said wooden frame.

  According to such a configuration, the fixing portion of the bracket is formed in a groove shape in a cross-sectional view and is fitted to the horizontal member of the wooden casing, so that the wooden casing is contracted and deformed by drying or the like. Even so, the bracket will not come off.

  Further, in a normal state, the guide rail is preferably separated from the car.

  According to such a configuration, since the guide rail is separated from the car in normal times (except during earthquakes or strong winds), the stress or vibration caused by the car or the hoisting machine is normally applied to the wooden frame. Is never transmitted. Therefore, it is not necessary to consider these stresses and vibrations in the wooden frame.

  According to the elevator structure according to the present invention, in a wooden building, it is possible to reduce the construction cost and the construction period while improving the efficiency of the elevator installation space.

A pulley 23 is provided at the upper end of the rear guide rail WG to hang the rope 8. The guide rail WG is fixed by welding to the first bracket H1 and the second bracket H2.

  As shown in FIGS. 1 and 2, the car 6 is a housing for carrying a load. The car 6 is a housing having a hexahedron structure in which a metal frame is provided with a metal plate. On both side surfaces 6a and 6b of the car 6, guide shoes 6c and 6c to be fitted to the guide rail G are respectively installed. An entrance / exit I is provided on the front side of the car 6. Two pulleys 21 for hanging the rope 8 are installed on the bottom surface of the car 6. The structure and shape of the car 6 and the position and number of the guide shoes 6c are not limited. The guide shoe 6c may be a sliding guide shoe or a roller guide.

  The hoisting machine 7 is an apparatus for driving the rope 8 and raising and lowering the car 6 in the elevator hoistway S as shown in FIGS. 1, 2 and 3. The hoisting machine 7 is fixed between the right side wall of the elevator hoistway S and the car 6 and behind the counterweight 9, and is fixed to the foundation 60 via the legs 7b. The hoisting machine 7 includes a sheave 7 a for transmitting a driving force to the rope 8.

In other words, all the vertical loads acting on the elevator apparatus E are supported by the foundation 60 and do not act on the wooden frame B.

(First bracket)
Next, the 1st bracket H1 which fixes the guide rails G and WG to the horizontal member 100 of the wooden frame B is demonstrated in detail (refer FIG.4 and FIG.6).
The 1st bracket H1 is installed in the horizontal member 100 of the 2nd floor floor panel 91, as shown in FIG.
As shown in FIG. 4 (d), the first bracket H1 is mainly composed of a fixed portion 1 and an extended portion 2 extended from the fixed portion 1, and has an F-shaped cross section. Yes. Although the material is not particularly limited, in the present embodiment, the first bracket H1 is made of metal.

  The fixing portion 1 is a portion that is fixed to the upper surface 101 and both side surfaces 102 and 103 of the horizontal member 100 and has a U-shaped cross section (groove shape). Since the fixed portion 1 has a U-shaped cross section, the fixed portion 1 can be fitted to the horizontal member 100 of the wooden frame B. The fixed portion 1 includes a horizontal portion 11 and a first vertical portion 12 and a second vertical portion 13 that are suspended from the lower surface of the horizontal portion 11.

  The horizontal portion 11 is a portion placed on the upper surface 101 of the horizontal member 100. The horizontal portion 11 has a thin rectangular shape in which the thickness direction is the vertical direction. The length of the horizontal part 11 in the left-right direction (the length from the outer end part 11a to the place in contact with the second vertical part 13) is slightly larger than the width of the horizontal member 100 in this embodiment.

  As shown in FIG. 6A, the first vertical portion 12 is a portion that contacts the side surface 102 of the horizontal member 100 on the side opposite to the elevator hoistway S side. The first vertical portion 12 has a thin rectangular shape with the plate thickness direction as the left-right direction. Although the first vertical portion 12 is joined to the horizontal portion 11 by welding, the horizontal portion 11 and the first vertical portion 12 may be formed by bending a single rectangular metal plate. As shown in (c) of FIG. 4, the first vertical portion 12 includes a front side and a rear side at an intermediate position between the upper end portion 12 a joined to the horizontal portion 11 and the lower end portion 12 b of the first vertical portion 12. Two circular bolt holes 50 are provided, one at a time.

  The 2nd vertical part 13 is a part contact | abutted to the side surface 103 by the side of the elevator hoistway S of the horizontal member 100, as shown to (a) of FIG. The second vertical portion 13 is joined to the horizontal portion 11 by welding. The 2nd vertical part 13 is exhibiting the rectangle of a thin plate which made the plate | board thickness direction the left-right direction. As shown in FIG. 4A, the second vertical portion 13 includes a front side and a rear side at an intermediate position between the upper end portion 13 a joined to the horizontal portion 11 and the lower end portion 13 b of the second vertical portion 13. Two circular bolt holes 50 are provided, one at a time. One nail hole 51 is provided above and below the bolt hole 50. By fixing bolts and nuts 52 (fixing members) to the bolt holes 50 of the first vertical portion 12 and the bolt holes 50 of the second vertical portion 13, the first bracket H <b> 1 falls off the horizontal member 100. Can be prevented.

  The extension part 2 is a part for fixing the guide rails G and WG to the horizontal member 100. As shown in FIG. 4 (d), the extending portion 2 is formed by extending in the horizontal direction into the elevator hoistway S from a position where the horizontal portion 11 of the fixed portion 1 is in contact with the second vertical portion 13. Guide rails G and WG are fixed to the extended end 2a, which is the tip of the extended portion 2, by welding or the like. In the present embodiment, the shape of the extending part 2 is a thin rectangular plate whose vertical direction is the thickness direction. Therefore, the extending part 2 is easily bent in the vertical direction as shown in FIG. In the present embodiment, the horizontal portion 11 and the extending portion 2 of the fixed portion 1 are a single plate-like component, but the horizontal portion of the fixed portion 1 is formed by bending a single member into a U-shape. 11 may be formed by welding the extending portion 2 in the horizontal direction.

(Second bracket)
The second bracket H2 is installed at the top of the elevator hoistway S. The second bracket H <b> 2 is fixed to the horizontal member 100 of the ceiling panel 10. The second bracket H2 is different from the first bracket H1 in the shape of the extending portion 2A. Hereinafter, the configuration of the extending portion 2A will be mainly described.

  As shown in FIG. 5 (d) and FIG. 7 (a), the extending portion 2A has an inverted L-shaped cross section, and extends upward from the upper end of the second vertical portion 13. And a horizontal extension 2AB that is bent at a right angle from the upper end of the base 2AA and extends in the horizontal direction. Guide rails G and WG are fixed to a horizontal extending end 2ABa that is a tip of the horizontal extending portion 2AB.

  Further, a support piece 3 is installed in a bent portion 2AC that is a portion bent between the base portion 2AA and the horizontal extending portion 2AB. The support piece 3 is a rib for reinforcing the bent portion 2AC, and has a thin right-angled triangle shape. In the present embodiment, the support piece 3 is joined to the base 2AA, but is not joined to the horizontal extension 2AB.

  When the elevator apparatus E is constructed, a temporary lifting beam L is installed on the pair of left and right horizontal extending portions 2AB. The lifting beam L is removed after the elevator apparatus E is installed.

(Effect of elevator structure)
Next, the function and effect of the elevator structure C will be described.
As shown in FIGS. 1 and 3, the guide rails G and WG are erected on the slab 61 of the foundation 60. Therefore, the load of the car 6 and the counterweight 9 is transmitted to the guide rails G and WG via the rope 8 and is transmitted from the guide rails G and WG to the slab 61 of the foundation 60.
Further, in the hoisting machine 7 (drive mechanism), the leg portion 7 b at the lower part of the hoisting machine 7 is fixed to the slab 61 of the foundation 60. Thereby, the load (self-weight and pulling-out load) of the hoisting machine 7 is directly supported by the slab 61 of the foundation 60 without passing through the wooden frame B.

Therefore, according to the elevator structure C according to the present embodiment, it is not necessary to install the steel frame support that has conventionally supported the loads of the elevator apparatus E and the hoisting machine 7 in the elevator hoistway S. The construction cost can be reduced, and it is not necessary to consider the production period of the steel frame and the preceding construction period. Further, since it is not necessary to expect a space for installing the steel frame in the elevator hoistway S, it is possible to improve the efficiency of the elevator installation space. Further, since the steel frame is not required and the car 6 and the communication parts 41 and 55 of the elevator hoistway S can be brought closer to each other than the conventional one, it is not necessary to specially order the three-way frame of the elevator platform. , 52 can be used. Therefore, the construction cost and the construction period can be reduced.
Further, since the guide rail G is separated from the car 6 in the normal time, the stress and vibration from the car 6 and the hoisting machine 7 are not transmitted to the wooden case B in the normal time. Therefore, it is not necessary to consider these stresses and vibrations in the wooden frame B.

According to the elevator structure C according to the present embodiment, the extending portion 2 of the first bracket H1 is configured in a thin plate shape that extends in the horizontal direction with the plate thickness direction as the up and down direction. Can be accommodated by the thin plate-like extension portion 2 of the first bracket H1 being in the vertical direction according to the relative displacement (see FIG. 6B). , WG can be prevented from being displaced or distorted.
Further, the fixing portion 1 of the first bracket H1 is formed in a groove shape in a cross-sectional view and is fitted to the horizontal member 100 of the wooden casing B, so that the wooden casing B is contracted by drying or the like. Even if deformed, the first bracket H1 will not come off.

  In the second bracket H2 according to the present embodiment, the extending portion 2A is configured in an L shape in a sectional view, and the support piece 3 is provided in a portion in the L shape in a sectional view. The beam L can be supported. Further, since the support piece 3 is not joined to the horizontal extension portion 2AB, even if the wooden casing B contracts or deforms due to drying or the like, the thin plate-like horizontal extension of the second bracket H2 conforms to the relative displacement. This can be dealt with when the protruding portion 2AB is directed upward (see FIG. 7B), and it is possible to prevent the guide rails G and WG from being displaced or distorted. At this time, since the bent portion 2AC is deformed to an obtuse angle, the separation between the guide rail G and the gypsum board 97 can be kept constant.

Although the embodiments of the present invention have been described above, design changes can be made as appropriate without departing from the spirit of the present invention. For example, the elevator structure C of the present invention can be used not only in a two-story wooden frame B building but also in a three-story or four-story wooden frame B building. As for the construction method, not only the frame wall method but also the shaft method can be adopted. When other construction methods are adopted, wooden members and names constituting the wooden frame B are changed.
The elevator apparatus E may also have a machine room. Further, instead of the traction type, a winding drum type or a hydraulic type may be used.
The foundation 60 directly below the wall constituting the elevator hoistway S does not perform underfloor ventilation by the spacer 72.

  The hoisting machine 7 (drive mechanism) may be installed not in the elevator hoistway S but in a space around the elevator hoistway S as long as no load is applied to the housing B. For example, a machine room or the like may be provided on the side of the elevator hoistway S, and the hoisting machine 7 may be installed in the machine room communicating with the elevator hoistway S.

  If the wooden frame B contracts or deforms due to drying or the like and changes in floor height, it can be handled by the landing position sensor plate. With the landing position sensor plate, the current floor position can be recognized and the floor can be accurately landed. The displacement exceeding about 10 mm may be dealt with by adjusting the mounting position of the landing position sensor plate.

  Moreover, you may use the 3rd bracket (not shown) which does not have the support piece 3 in bending part 2AC instead of the 2nd bracket H2. Since the third bracket does not have the support piece 3 at the bent portion 2AC, the angle of the bent portion 2AC can be changed to an acute angle or an obtuse angle, and when the wooden frame B contracts or deforms due to drying or the like. Relative displacement can be absorbed.

  Moreover, although said embodiment demonstrated the case where the guide rails G and WG and brackets H1 and H2 were mainly connected directly, this invention is not limited to this. For example, a flat bar (not shown) may be interposed between the guide rails G and WG and the brackets H1 and H2. In this case, when the wooden frame B contracts or deforms due to drying or the like and changes in floor height, the flat bar is deformed to absorb the distortion.
