Description

[0001]
BACKGROUND OF THE INVENTION
The present invention belongs to the technical field of a method for constructing a large space partition screen for partitioning an internal space in order to provide a large space such as a dome or a stadium for multipurpose use, and more specifically, it can be safely performed as work on the floor level. In addition, the present invention relates to a method for constructing a large space partition that does not require special power from an electric motor or the like.
[0002]
[Prior art]
Conventionally, as a method for constructing a large space partition curtain in a dome, a stadium or the like, when there is a roof frame or a ceiling, a method of lifting the curtain using these is generally performed (for example, the present application). (See the invention described in Japanese Patent Laid-Open No. 9-317067).
[0003]
In addition, some methods such as building a curtain pole using a pillar machine that moves on the floor have been implemented.
[0004]
[Problems to be solved by the invention]
The conventional method of lifting a curtain using a roof frame or ceiling is based on the premise that such equipment is prepared in advance on the ceiling or the like. Inevitably, the ceiling or the like needs to have a strength suitable for hanging the curtain, and must be designed and manufactured by incorporating equipment, resulting in high costs. Moreover, when a failure or malfunction occurs in the curtain lifting equipment, there is no choice but to assemble a high scaffold that reaches the ceiling or the like, which is very troublesome and requires dangerous work at high places.
[0005]
The method of building a curtain pole using a building pole machine that moves on the floor is quite meaningful from a technical point of view, but it is like a pillar machine for work that constitutes a small space curtain that is infrequent. It is an economic burden to own and transport heavy machinery. In some cases, there are problems such as damage to the floor structure due to the weight of heavy machinery, and significant damage to turf planted on the floor.
[0006]
The object of the present invention is not to use any equipment such as a ceiling, and it is not necessary to prepare heavy machinery, and it is possible to carry out a safe work on the floor level with a small number of people, without requiring the power of an electric motor or the like. It is to provide a method for constructing a large space divider with high accuracy and high quality at low cost efficiently and quickly with a prefabricated construction with simple tools.

[0012]
3 to 6 conceptually show the main steps of the procedure for implementing the method of constructing the large space partition of the present invention, particularly the procedure for building up the curtain pole.
[0013]
First, in FIG. 3, a curing sheet 4 is laid on the floor surface 3 and a column material 5, an upper beam material 6, a lower beam material 7, an intermediate column material 8 and the like are placed on the floor to be assembled immediately before assembling the curtain pole. Indicates the state. At this time, the anchor pole 10 has already been built on the floor 3. A guide sheave 11 is attached to the upper beam member 6 in advance, and a suspension wire 12 is wound around the upper beam member 6. The above-mentioned materials are connected using joints or connected to each other to assemble a curtain pole K (FIG. 4) having a rectangular frame structure. Details of the structure are shown in FIGS.
[0014]
Next, FIGS. 4 and 5 show that the building pole wire 35 pulled out from the manual pole winch 31 attached to the anchor pole 10 is connected to the curtain pole K, and the pole winch 31 is driven and built up. Shows the stage. FIG. 6 shows a stage in which the vertical posture is completely erected. At this time, the lower end portions of the pillars 5 and 8 of the curtain pole K are rotatably supported by inserting the support pins 33 into the U grooves of the bearing plates 32 of the anchor pole 10 as shown in FIG.
[0015]
In more detail, the structure of the anchor pole 10 and its construction method will be described.
The anchor pole 10 is a processed metal tube having an outer diameter of 165 mm and a total length of about 3500 mm. As shown in FIGS. 7 to 9, the anchor pole 10 is placed on the carriage 15 in a posture standing in a substantially vertical posture and transported on the floor surface 3. As a means for this, the wire 18 drawn out from the manual winch 17 installed on the side frame 16 of the carriage 15 is U-turned downward from the guide sheave 19 attached to the upper end of the side frame 16, and the tip of the wire 18 is The anchor pole 10 is fixed to a bracket 20 prepared in advance at a relatively upper position. Then, the winch 17 is wound up to lift the anchor pole 10 in a vertical posture, and the tip of the anchor pole 10 is supported on the base plate 14 of the carriage 15 and is transported on the floor as it is.
[0016]
As shown in FIGS. 7 and 8, when the carriage 15 reaches the position directly above the pole hole 22 prepared in advance on the floor surface 3, after locking the wheel, the tip of the anchor pole 10 is slightly lifted to slightly lift the platform. The plate 14 is slid backward and this time the winch 17 is loosened, and the anchor pole 10 is slowly lowered into the pole hole 22 immediately below.
[0017]
The pole hole 22 has a diameter of 178 mm and a depth of about 800 mm, for example, in a concrete base portion of a floor structure. Therefore, the anchor pole 10 can be easily and safely built even by one person (invention of claim 2).
[0018]
As shown in FIG. 10, the anchor pole 10 thus built is filled in the gap 23 with the pole hole 22 and fixed firmly in the pole hole 22 (the invention according to claim 3).
[0019]
The wedge 23 shown in FIG. 10 is attached to the lower end portion of the screw shaft 24 that is supported vertically downward by a plurality of support plates 26 on the side surface of the anchor pole 10. The screw shaft 24 is pushed down by turning the nut 25, and the wedge 23 is pushed into the base 27 that forms the mouth of the pole hole 22. Therefore, the fixed state of the anchor pole 10 is strongly stabilized by the wedge effect. Three wedges 23 are arranged at three locations obtained by dividing the outer periphery of the anchor pole 10 into three equal parts, and the inclination (verticality) of the anchor pole 10 can be adjusted. Of course, if the wedge 23 is pulled out, the anchor pole 10 can be removed freely.
[0020]
A bracket 30 is prepared at a relatively upper position of the anchor pole 10 constructed as described above, and a manual pole winch 31 is attached (FIG. 11). A bearing plate 32 is fixed to the lower portion, and a support pin 33 attached to the lower ends of the pillars 5 and 8 of the curtain pole K described above is fitted in the U groove of the bearing plate 32 so as to be rotatably supported. . A guide sheave 34 is installed at the upper end of the anchor pole 10, and the building pillar wire 35 drawn out from the pole winch 31 is connected to the bracket 36 of the curtain pole K through the guide sheave 34 (see FIG. 11). .
[0021]
In short, as shown in FIGS. 3 and 4 and described above, the curtain pole K composed of the upper beam 6 and the lower beam 7 and the pillars 5 and the intermediate pillars 8 on the floor is assembled and laid down on the floor. First, the lower end portions of the pillars 5 and 8 of the curtain pole are lifted, and the support pins 33 attached thereto are fitted into the U-groove portions of the bearing plate 32 of the anchor pole 10 so as to be rotatably supported. Next, a building pole wire 35 drawn from a pole winch 31 attached to the anchor pole 10 is connected to a bracket 36 of the curtain pole K laid on the floor, and the curtain pole K is manually driven by the pole winch 31. Wake up slowly little by little. At this time, it is also preferable to assist a plurality of workers to raise the columns 5 and 8 of the curtain pole K. Thus, the curtain pole K is finally built up to a vertical posture. Then, the pole winch 31 is tightly wound, and the pillars 5 and 8 of the curtain pole K are strongly coupled to the anchor pole 10 and kept in a fixed state as shown in FIG. Further, it is also possible to strongly bind the anchor pole 10 and the pillars 5 and 8 of the curtain pole K with a band or the like.
[0022]
Therefore, the method of removing the curtain pole K after it has been used can be easily laid down on the floor 3 again by slowly loosening the pole winch 31 little by little, and the removal work per pole is After all it can be done safely by one person.
[0023]
Next, a procedure for stretching the curtain using the curtain pole K constructed as described above will be described.
