And the uppermost layer 13. The lowermost block 11 and the intermediate block 12 are formed with a bridging portion 14 that bridges the corridor 1. In the bridging portion 14, an intermediate lower portion 14a bridged over the corridor 1 and a side portion 14b for preventing falling are integrally formed in a front U-shape. Since this partition structure is a type that is attached to the corridor 1 as shown in FIG. 8, if it is a five-story apartment building, the bridge portion 14 is provided at five locations as shown in FIGS. Formed.

Since the lowermost block 11 is placed on the foundation B projecting from the ground, the height of the lowermost block 11 is lower than that of the intermediate block 12 and the uppermost block 13. Since the bridging portion 14 of the lowermost block 11 spans the corridor 1 on the first floor, an intermediate lower portion 14a of the bridging portion 14 is formed at the lower portion of the opening-side end surface of the block 11, and the side portion 14b is formed of the block. Is formed over substantially the entire length of the end face on the opening side of. In the bridging portion 14 of the intermediate layer block 12 that spans the corridor 1 from the second floor to the fifth floor, the intermediate lower portion 14a is formed in the middle of the opening side end surface, and the side portion 14b is formed from the middle to the upper end of the opening side end surface. It is formed in. As shown in FIG. 2, a rain-proof screen 15 is provided between the side portions 14b of the bridging portion 14 having the vertical positional relationship.

Since the block 13 in the uppermost layer does not face the corridor 1, the bridging portion 14 is not formed, and the beam plate portion 13a is formed on the upper end of the opening side as shown in FIG. A caulking material is applied to the upper surface of the uppermost block 13 and a roof 16 is covered. The roof 16 is slightly larger than the block, and the upper surface is an inclined surface with the opening side of the block lowered, and a gutter 17 is attached to the lowered side as shown in FIG. Are formed with ridges.

As shown in FIG. 4, such a roof 16 is fixed to the upper surface of the uppermost block 13 by bolts 18. As shown in FIG. 1, the bolts 18 fasten the upper end face of the beam plate portion 13a and the upper end surface on the side facing the beam plate portion 13a at four places. A rainproof screen 15 is also provided between the roof 16 and the side portion 14b of the bridge portion 14 formed in the uppermost (fourth from the bottom) block 12 in the middle layer.

The blocks 11, 12, and 13 of the lowermost layer, the intermediate layer, and the uppermost layer include a plurality of portions that can be separated and connected to each other. As shown in FIG. 6, the lowermost layer block 11 (or the intermediate layer block 12) forms a portion 11a (12a) constituting a back partition, a side partition and a side portion 14b of the bridging portion 14. Parts 11b, 11b (12b, 12b), and a part 11c (12c) constituting an intermediate lower part 14a of the bridging part 14. For the parts 11a (12a) and 11b (12b), fixing bolts 32 are inserted through bolt holes 30 formed at both ends and bolt holes 31a of a steel plate 31 applied to both sides thereof. The nut 33 is screwed into the tip of the bolt 32 to connect and integrate them. Also, the part 11b (12b) and the part 11c (12c) are formed by inserting the embedded bolt 35 on the part 11b (12b) side into the bolt hole 36a of the integrated steel plate 36 through the part 11c (12c). Both are connected and integrated by screwing a nut 33 to the tip. When each part is connected, it becomes a block whose plane shape is almost U-shaped.

As shown in FIG. 7, the block 13 in the uppermost layer includes a portion 13a forming the rear partition, portions 13b and 13b forming the side partition, and a portion 13c forming the front partition. Consists of In each of the parts 13a and 13b, and the parts 13b and 13c, a fixing bolt 32 is inserted through a bolt hole 30 drilled at both ends and a bolt hole 31a of a steel plate 31 applied to both sides thereof. The nut 33 is screwed into the tip of the bolt 32 to connect and integrate them. When the respective parts are connected, the block has a rectangular shape in plan view.

In the lowermost, middle and uppermost blocks 11, 12, and 13, a large number of communication holes 10a for inserting a large number of high tension shaft cores 20 are formed continuously in the vertical direction. Has been established. It is preferable to use a PC steel bar as the high tension shaft core 20. Hereinafter, the high tension shaft core will be described as the PC steel bar 20.

The PC steel bar 20 is inserted from inside the foundation B to the uppermost block 13. However, since the PC steel bar 20 is cut to a certain length, it is impossible to insert the PC steel bar 20 from the inside of the foundation B to the upper end of the uppermost block 13 with one PC steel bar 20. Therefore, in this case, three PC steel bars 20 per row are connected by a coupler 21 as shown in FIG. A male screw is formed at the upper end of the PC steel rod 20, and a nut 22 for pulling up the PC steel rod 20 is screwed to the male screw. A donut-shaped support plate 23 for pressing the block is fitted under the nut 22.

In the upper part of the communication hole 10 a formed in the first and third blocks 12, 12 from the bottom of the intermediate layer, a seat hole part 10 b into which the supporting plate 23 is fitted is formed, and the second hole from the bottom of the intermediate layer is formed. An enlarged diameter portion 10c for accommodating the coupler 21 and the nut 22 in the communication hole 10a is formed below the communication hole 10a formed in the fourth block 12 and the fourth block 12. Further, a deep seat hole 10d for accommodating the support plate 23 and the nut 22 as shown in FIG. 4 is formed above the communication hole 10a formed in the uppermost block 13.

Reinforcing bars 24 are embedded in the upper portions of the blocks 12 and 13 of the intermediate layer and the uppermost layer in which the seat holes 10 b and 10 d are formed. When the nut 22 is tightened, the supporting plate 23 presses the blocks 11, 12, and 13 downward as a reaction of pulling the PC steel bar 20, and the plurality of blocks 11, 12, and 13 are tightened. Even if the support plate 23 is pressed and a load is applied to the blocks 12, 13, the blocks 12, 13 are not damaged by the reinforcing bars 24.

A mortar (not shown) for preventing water from entering is filled in the communication hole 10a into which the PC steel rod 20 is inserted. Then, an adhesive (not shown) for integration is applied to the joint surfaces of the blocks 11, 12, 13.

Next, a method of constructing such a partition structure will be described. First, a foundation B in which lower end portions of a number of PC steel bars 20 are embedded is constructed. The support plate 23 is fixed to the lower end of the PC steel bar 20 and the support plate 23 is embedded in the foundation B so that the PC steel bar 20 does not come out of the foundation B. Non-shrinkable mortar is applied to the upper surface of the base B, and the lowermost block 11 is placed. The block 11 may be prepared by assembling the parts 11a, 11b, 11c in a substantially U-shape in plan view on the base B, or the parts 11a, 11b, 11c may be placed on the base B. You may make it assemble when mounting. The same applies to a case where a block 12 of an intermediate layer and a block 13 of an uppermost layer, which will be described later, are placed on a block below.

A number of PC steel rods 20 are drawn out from the many communication holes 10 a of the lowermost block 11 placed on the foundation B so as to be longer than the height of the intermediate layer block 12. Subsequently, an adhesive is applied to the upper end surface of the lowermost block 11 and the lowermost block 12 of the intermediate layer is placed. At this time, the upper portions of the large number of PC steel bars 20 are slightly led out from the large number of communication holes 10a of the lowermost block 12 of the intermediate layer.

The mortar is filled in the communication hole 10 a into which the PC steel rod 20 is inserted. The support plate 23 is fitted to the end of the PC steel bar 20 slightly extended from the upper end surface of the lowermost block 12 of the intermediate layer, and the support plate 23 is inserted into the seat hole 10a. Then, the nut 22 is screwed into the male screw formed at the upper end of the PC steel rod 20, whereby the PC steel rod 20 is pulled up. As a reaction, the support plate 23 is moved to the lowermost block 12 of the intermediate layer. Press. Then, the lowermost block 11 and the lowermost block of the intermediate layer are firmly tightened on the foundation B. Moreover, the base B and the lowermost block 11 are united by mortar, and the lowermost block 11 and the lowermost block 12 of the intermediate layer are integrated by an adhesive.

Next, the upper part of the lower PC steel rod 20 slightly derived from the upper end surface of the lowermost block 12 of the intermediate layer and the lower part of the intermediate PC steel rod 20 are joined by a coupler 21. Then, an adhesive is applied to the upper end surface of the lowermost block 12 of the intermediate layer, and the second lowermost block 12 of the intermediate layer is stacked thereon. A diameter-enlarging portion 10c is formed in the communication hole 10a of the second block from the bottom of the intermediate layer. A nut 22 that pulls up the PC steel rod and two PC steel rods are formed in the diameter-enlarging portion 10c. A coupler 21 in which 20, 20 are connected is stored.

The PC steel rods 20 joined by the coupler 21 are inserted into the communication holes 10 a of the second and third blocks 12, 12 from the bottom of the stacked intermediate layer, and the upper end is positioned from below the intermediate layer. It is slightly derived from the upper end face of the third block 12. Then, the mortar is filled into the communication hole 10a as described above, and the plurality of blocks 12 in the middle portion of the middle layer are fastened by the support plate 23 and the nut 22, thereby being firmly integrated with the foundation B.

Next, in the same manner as described above, the middle PC steel rod 20 is joined to the upper PC steel rod 20 by the coupler 21, and an adhesive is applied to the upper end surface of the third block 12 from the bottom of the intermediate layer. Then, the fourth (uppermost) block 12 from the bottom of the intermediate layer is stacked thereon. Then, an adhesive is applied to the upper end surface of the fourth block 12 from the bottom of the intermediate layer, and when the uppermost block 13 is overlaid thereon, the PC steel rod is inserted into the communication hole 10a of the uppermost block 13. 20 is inserted.

The upper end of the PC steel rod 20 is located in the deep seat hole 10 d of the uppermost block 13, and the upper end of the PC steel rod 20 in the deep seat hole 10 d is provided with a support plate 23. The nut 22 is screwed into the male screw formed at the upper end. When the nut 22 is tightened, the support plate 23 presses the uppermost block 13 to firmly tighten the upper block 12 and the uppermost block 11 of the intermediate layer. In this way, the base B, the lowermost block 11, the intermediate layer 12, and the uppermost block 13 are firmly integrated together with the adhesive.

The mortar is also filled in the communication holes 10 a of the uppermost block 13. A caulking material is applied to the upper end surface of the uppermost block 13 and a roof 16 is covered. The roof 16 is fixed to the uppermost block 13 by four bolts 18 to complete the partition structure. On the other hand, the safety fence of the corridor 1 in the part where this partition structure was constructed is removed, and it becomes the entrance to the elevator cab.

The inside surrounded by the partition structure is used as a car room hoistway 3 and a machine room 4 for moving the car room up and down. A cab is provided in the cab hoistway 3, and a machine is installed in the machine room 4. Doors (not shown) are attached to the openings of the blocks 11, 12, and 13, the surface of the bridging portion 14 is painted, and a steel plate is provided between the middle lower portion 14a of the bridging portion 14 and the corridor 1. 5 is placed.

Next, with reference to FIG. 9, a description will be given of a characteristic portion of a partition structure of a car hoistway of a middle-rise apartment elevator provided alongside a stair 2 provided in a vertical direction as shown in FIG. I do. In the case of the stairs 2 reciprocating in a square shape from the doorway of each dwelling as shown in FIG. 9, the landing 2a provided at the turning point faces the outside of the building. This landing 2a is provided between the first and second floors, between the second and third floors, and between the fourth and fifth floors in the case of a five-story middle-rise house.

It is possible to use all of these landings 2a as the entrances and exits D of the elevator cab. However, in order to reduce the number of places where the elevators stop, the entrances and exits D of the cabs are provided here. It will be provided at three places, on the ground, at the landing 2a between the second and third floors, and at the landing 2a between the fourth and fifth floors. Residents on the second floor do not have a heavy burden to go up and down stairs 2 to the ground, and when they need to use the elevator, they only need to go up stairs 2 by half as much as they would on the second and third floors. The landing D provided at the landing 2a can be used.

The resident on the third floor can use the entrance D provided on the landing 2a between the second and third floors by going down the stairs 2 by half of the normal level. Residents on the fourth floor go up stairs 2 by half of the normal level, and residents on the fifth floor go down stairs 2 by half the normal level, to landing 2a between the fourth and fifth floors, respectively. The provided entrance / exit D can be used. Therefore, even if the landing D is not provided at the landing 2a between the first and second floors and the landing 2a between the third and fourth floors, the residents of any floor can use the elevators equally. it can.

As described above, the partition structure in which the entrances D are provided at three locations is formed by alternately stacking the blocks with the bridge portions 14 and the blocks 10 without the bridge portions 14 in a cab. Form a hoistway. A plurality of communication holes 10a are also formed in this block 10. A mortar is filled by inserting a PC steel rod 20 into the communication hole 10a, and the blocks 10 are firmly tightened by pulling the PC steel rod 20. An adhesive is applied between the blocks 10 to be integrated. Since a specific construction method is the same as that of the above-described embodiment, the description is omitted.

In the above-described embodiment, the case where the PC steel bar 20 is used as an example of the high-tension shaft core 20 has been described. However, the present invention can be similarly performed with one piano wire. it can. Further, as the partition structure, a self-propelled elevator that does not require a machine room as disclosed in pages 102 to 103 of the April 20, 1998 issue of Nikkei Architecture can be used.
