Description

  The present invention relates to a bulkhead structure of a car hoistway of a retrofit elevator for an apartment house for easily installing an elevator in an existing apartment house where no elevator is installed.

The four-story and five-story middle-rise apartments often have no elevator installed, and rising and descending stairs has been a major burden for residents on the upper floors. Therefore, for the purpose of easily installing an elevator in an existing middle-rise apartment building, the applicant of the present application is to stack a plurality of plane-shaped substantially U-shaped concrete blocks on the foundation ground and open toward the corridor or stairs. We have developed a technology for constructing a bulkhead structure (hereinafter referred to as a “bulk structure”) for a cage hoistway of a retrofit elevator for an apartment house. According to this construction technique, a partition wall structure can be constructed in a short time by a relatively simple operation without dismantling or remodeling an existing house.
Japanese Patent No. 3168337

  However, the bulkhead structure according to the above prior art is made of concrete and has a large weight, so it requires a solid foundation ground. In many cases, the existing foundation ground is insufficient and new foundation work must be performed. There was a problem. In addition, while work at the construction site is short, it requires work to form concrete blocks in advance outside the construction site, and requires a great deal of cost and labor to transport the molded heavy concrete blocks. There was a problem that it took.

  Therefore, in order to reduce the weight of the partition wall structure, an attempt was made to construct a partition wall structure by attaching an exterior panel to the outer surface of a steel frame frame assembled with steel materials such as H-shaped steel. In that case, if the steel frame is divided into multiple stages and an exterior panel is attached in advance to the outer surface of each of the divided steel frames, the bulkhead division unit is placed on the foundation ground. Since it is only necessary to stack in order and install the roof on the uppermost partition unit, the work at the site is simplified. In order to build a partition structure in this way, how to fix the partition unit in the lowest layer to the foundation ground, how to connect the partition units, and how to attach the roof It becomes a problem.

  In order to solve this problem, the present invention has taken the following technical means. That is, the bulkhead structure according to the present invention is a bulkhead structure provided alongside a corridor provided in the horizontal direction or a staircase provided in the vertical direction, and a vertical steel material arranged at positions corresponding to the four corners of the cage hoistway. A partition wall dividing unit is constructed by attaching an exterior panel to the outer surface of a steel frame that is a combination of horizontal steel members that connect adjacent vertical steel members to each other, and this partition wall dividing unit is stacked in layers on the foundation ground. It is constructed by attaching a roof to the upper surface of the upper partition dividing unit. In this bulkhead structure, against the horizontal steel plate fixed to the foundation ground, the lower end of the vertical steel material of the lowermost partition unit is abutted, and the steel plate and the vertical steel material of the lowermost partition unit are It is characterized by fixing the lowermost partition wall dividing unit to the foundation ground by welding.

  Further, the lower end of the vertical steel material of the upper partition wall partition unit is abutted against the horizontal steel plate fixed to the upper end surface of the vertical steel material of the lower partition wall partition unit, and the steel plate and the upper partition wall partition unit By welding the vertical steel material, the lower partition wall partition unit and the upper partition partition unit are connected.

  Furthermore, the roof is provided so as to incline in one direction, and at least the outermost side on the upper side of the incline is located on the inner side of the exterior panel, and the rain protection cover is provided on the exterior panel located on the outer side of the roof. And the inner end of the rain cover is extended to the top of the roof.

This partition structure is constructed as follows.
First, the lowest layer partitioning unit is installed on the foundation ground, and the lower end of the vertical steel material of the lowest partitioning unit is abutted against the horizontal steel plate fixed to the foundation ground. The vertical partition of the partition wall dividing unit is welded to fix the lowermost partition wall dividing unit to the foundation ground. This work can be easily performed in a short time because it only requires welding on site.

  Next, the partition layer splitting unit of the second layer (upper layer side) from the bottom was installed on the partition partition unit of the lowermost layer (lower layer side), and fixed to the upper end surface of the vertical steel material of the partition partitioning unit of the lowermost layer The bottom steel plate of the second partition partition unit is abutted against a horizontal steel plate, the steel plate and the vertical steel member of the second partition partition unit are welded, and the lowest partition partition unit and 2 It connects with the partition unit of the layer. When stacking three or more layers of partition partition units, the upper partition partition units are stacked on the lower partition partition unit, and both are fixed in the same manner as described above. These operations can be easily performed in a short time because only welding is performed on site.

  In the connection between the lowermost partition dividing unit and the second partition dividing unit, the vertical steel material of the partition dividing unit is H-shaped steel, and an H character is placed at the lower end of the vertical steel material of the upper partition dividing unit. It is advisable to provide a cutout portion by cutting out the image portion from the lower edge side.

  If the notch is provided, a welding tool is inserted into the notch from the opposite side across the horizontal portion of the vertical steel material, so that the steel plate of the lower partition wall dividing unit and the vertical partition of the upper partition partition unit are vertically inserted. It is possible to perform welding with the vertical portion of the letter H in the steel material. Therefore, the operator can perform all the welding work in the connecting work of the lower wall partitioning unit and the upper partitioning unit with the body positioned inside the steel frame, and the work is safe. In addition, work efficiency can be improved.

  Finally, the roof is mounted on the top partition unit. Since at least the outermost side on the upper side of the slope of the roof is located on the inner side of the exterior panel, the roof can be easily attached without forming a scaffold outside the uppermost partition unit. The exterior panel located outside the roof is protected from rain by a rain cover.

  This partition structure is mainly composed of a steel frame and an exterior panel that covers the outer surface thereof, and does not use concrete, so it is lightweight overall. For this reason, it can be constructed only by performing simple foundation work even in places where full-scale foundation ground is not constructed. In addition, since the lowermost partition wall dividing block can be installed on the horizontal foundation ground, the construction of the foundation ground becomes easy, and the construction period can be shortened and the cost can be reduced accordingly.

  As described above, the bulkhead structure of the elevator car elevator hoistway according to the present invention is a steel frame structure and lightweight, so it can be constructed only by simple foundation work, and a plurality of bulkhead divisions Units are stacked in layers on the foundation ground and the roof is attached to the upper surface of the uppermost partitioning unit, so the work on site is simple and the foundation ground of the lowermost partitioning unit Since it is easy to fix to each other, to connect the partition wall dividing units, and to attach the roof, it can be easily constructed in a short construction period. For this reason, when installing an elevator in an existing housing complex, especially when a large foundation ground cannot be built, when a resident must work while moving in, or when there are restrictions on the conditions of construction It became very effective.

  Hereinafter, an example (FIG. 8) in which a partition structure of an elevator car room hoistway is added to the stairway 20 provided in the vertical direction of a five-story apartment house, and a corridor provided in the horizontal direction of the five-story apartment house The present invention will be specifically described on the basis of an example (FIG. 10) in which the partition wall structure is additionally provided at 21.

First, the staircase in which the partition wall structure 1A is provided will be described. The staircase 20 is formed in a zigzag manner in a side view by connecting the front doors of the respective floors. A landing 20a is provided toward the outside of the building. Since this apartment house has five floors, the dance hall 20a exists between the first and second floors, between the second and third floors, between the third and fourth floors, and between the fourth and fifth floors. ing. It is possible to get on and off the elevator at all these landings 20a, but there are few merits even if the elevator is stopped at the landing 20a between the first floor and the second floor. You can get on and off the elevator at four places: the landing 20a (1) between the first and third floors, the landing 20a (2) between the third and fourth floors, and the landing 20a (3) between the fourth and fifth floors. Like that.

  As shown in FIG. 3, the partition wall structure 1 </ b> A is constructed by stacking and installing two partition wall dividing units U <b> 1 and U <b> 2 on the foundation ground 2 and attaching a roof 11 thereon. The square columnar space formed inside the both partition units U1 and U2 serves as an elevator car room hoistway 6 and a machine room 7 for raising and lowering the car room.

  Both partition wall dividing units U1 and U2 include steel frames 5 and 5 shown in FIGS. 4 (a) and 4 (b), respectively. The steel frame 5 is composed of four vertical H-shaped steel vertical steel members 3,... Arranged in correspondence with the positions of the four corners of the car room hoistway and the horizontal members connecting the adjacent vertical steel members. The main frame is composed of H-shaped steel transverse steel members 4,... In the direction, and a U-shaped frame 8 formed by combining H-shaped steel is integrally attached to the staircase side of the main frame. As shown in FIG. 2, the vertical steel members 3,... Are arranged so that the adjacent ones have different directions by 90 from each other. For this reason, the vertical steel members 3,... Compensate each other for strength weakness against bending and twisting, and the steel frame 5 has a highly rigid structure. In addition, the horizontal steel plate 31, ... is being fixed to the upper end part of the vertical steel materials 3, ... of the lower layer side partition division unit U1. A frame 5a for hanging and supporting the elevator cab is provided on the uppermost part of the steel frame 5 of the upper partition wall dividing unit U2.

  The upper partition wall dividing unit U1 is provided with three U-shaped frames 8, and the uppermost U-shaped frame 8 is mounted at the height of the upper end of the steel frame 5, and the second U-shaped frame from the top. The mounting position of the frame 8 is the height of the landing 20a (3) between the 4th and 5th floors, and the mounting position of the U-shaped frame 8 in the third step is that of the landing 20a (2) between the 3rd and 4th floors. It is said to be high. In addition, the lower partition wall dividing unit U2 is provided with only one stage of the U-shaped frame 8, and the mounting position thereof is the height of the landing 20a (1) between the second and third floors. In addition, the horizontal steel material 4 of each step | paragraph is provided according to the height of the said landing 20a except the highest thing.

  The exterior panels 10 are attached to the outer surface of the steel frame 5. At that time, the car room entrance 9 facing the corridor 20 side is opened in correspondence with the U-shaped frames 8,. Further, floor plates 12,... Are mounted on the U-shaped frames 8,.

Next, a construction method of the partition structure 1A using the partition unit U1 and U2 will be described.
First, a hole H is dug in an elevator installation location, and a flat foundation ground 2 made of concrete is constructed on the bottom surface of the hole H. At that time, as shown in FIG. 5, anchor bolts 30 are embedded at predetermined positions corresponding to the four corners of the car room hoistway. And the steel plate 31 is laid on the foundation ground 2 according to the position of the anchor bolt 30, and this steel plate is fixed with the anchor bolt 30 and the nut 32.

  A partition wall dividing unit U2 on the lower layer side is installed on the foundation ground 2. At this time, the lower end portion of the vertical steel member 3 is abutted against the upper surface of the steel plate 31, and the steel plate 31 and the vertical member 3 are welded W. Then, the periphery of the lower end part of the steel frame 5 to which the exterior panel 10 is not attached is solidified with mortar M, and the hole H is backfilled.

  Next, the upper partition wall partition unit U1 is installed on the lower partition wall partition unit U2. Also in this case, as in the case where the lower layer partitioning unit U2 is installed on the foundation ground 2, the vertical steel members 3, ... of the upper partitioning unit U1 on the upper surface of the steel plate 31 of the lower partitioning unit U2. The lower end is butted and the steel plate 31 and the vertical member 3 are welded W.

  Incidentally, at the lower end of the vertical steel members 3,... Of the upper partition wall partition unit U1, as shown in FIG. 6, a cutout portion 33 is formed by cutting out the H-shaped horizontal portion 3a of the H-shaped steel from the lower edge side. Is formed. For this reason, from the inside of the steel frame 5, the welding tool is inserted into the notch 33, and the H-shape in the steel plate 31 and the vertical steel material 3 is located on the outer side with the horizontal portion 3 a of the vertical steel material 3 interposed therebetween. Welding W of the welded portion with the vertical image portion 3b can be performed. After the welding of the welded portion between the steel plate 31 and the vertical portion 3b of the H shape in the vertical steel material 3 is finished, the steel plate 34 is applied so as to close the notch 33 from the inside of the steel frame 5, and the steel plate 34 is Weld to steel 3. Thus, by providing the notch 33 in the vertical steel member 3, the operator can keep the body positioned inside the steel frame 5 while the lower wall partition unit U2 and the upper partition unit U1. All welding operations in the connecting operation can be performed, the operation is safe, and the work efficiency can be improved.

  Finally, the roof 11 is attached on the upper partition wall dividing unit U1. In this embodiment, the roof 11 is formed of a folded plate and is inclined so as to have a gradient in the groove direction. The upper edge of the slope is positioned on the inner side of the exterior panel 10, and the inner end of the rain cover 35 that covers the exterior panel 10 extends to the roof 11. As described above, when the roof 11 is fitted into the exterior panel 10, the roof mounting operation does not have to be performed from the outside of the exterior panel 10, which is safe and does not require a scaffold or the like. It can be done at low cost and in a short time.

  The interior of the partition wall structure 1A thus completed is used as a car room hoistway 6 and a machine room 7. A car room 6 a is disposed in the car room hoistway 6, and a car room elevating machine 7 a is installed in the machine room 7.

  A door (not shown) that opens and closes is attached to the car doorway 9. The upper surface of the floor board 12 is finished with mortar, tile or the like.

The outer partition 20b of the landing 20a (1, 2, 3) is removed, and a steel plate 13 is placed in the gap between the landing and the floor plate 12 of the passage. A rain screen 14 and a handrail 15 are attached to both sides of the passage. In addition, rain screens 14 are attached to both sides of the cab entrance 9 on the ground.

  Since this partition wall structure 1 </ b> A is almost composed only of the steel frame 5 and the exterior panel 10..., It is lightweight. For this reason, the large scale does not require the foundation ground, and simple foundation construction is sufficient. Since the foundation ground 2 should just finish an upper surface flat, foundation construction can be performed in a short time. In some cases, the foundation ground of existing apartment houses can be used. In addition, the construction work of the partition wall structure 1A itself is very simple because the two partition partition units U2 and U1 are stacked and installed on the foundation ground 2, and the roof 11 is attached thereon. Moreover, it can be performed in a short time.
