Description

  The present invention relates to a ceiling transport mechanism and a construction method for constructing a ceiling of a building such as a concert hall or a theater.

Conventionally, when constructing ceilings installed in large space buildings such as theaters and concert halls, the entire ceiling is assembled with air conditioning and electrical equipment on the floor such as the ground floor, and lifting machines such as chain blocks. There is a method of lifting a ceiling assembled using a single at a time and installing it on the lower surface of the roof (for example, see Patent Document 1). However, the method of lifting the whole ceiling at once in this way is that if there is a floor such as a spectator seat that protrudes to the space side on the intermediate floor of a large space building, the ceiling is extended from the ground floor to the specified ceiling installation location. When lifting, construction was considered difficult because the audience seats would interfere and interfere.
As another ceiling construction method that can cope with a building with a protruding audience seat, there is a method in which a work scaffold is installed from the ground floor to the entire ceiling and a stage is erected. In this case, after completion of the frame construction, a steel frame is attached to the ceiling of the large space building using a crane, etc., and then the plane of the large space building is raised to a height convenient for the ceiling construction. In the meantime, there was a temporary work platform that occupies almost the entire surface. And in order to construct a ceiling on the work scaffold installed in this way, it is common to install lifting machines such as lifts and temporary elevators that lift finishing materials and equipment materials.
Further, as a method of not installing the work scaffold over the entire ceiling surface, for example, Patent Document 2 discloses a method of constructing a mobile scaffold.
Patent Document 2 uses a traveling rail of an overhead crane installed in a large space building, suspends a work stage (scaffold) having a predetermined space with an overhead crane, and sequentially moves it to a ceiling construction site. Is to build.

However, the conventional construction method on the ceiling of a large space building has the following problems.
In the case of using a total scaffold from the ground, both the height and the area become large, and there are problems that the cost of scaffolding materials and transportation increases, and that it takes time and labor to assemble and disassemble the scaffold. Moreover, while the scaffolding is in place, there is a drawback that it is not possible to perform construction such as the ground floor directly under the scaffolding, which affects the construction period.
Moreover, although patent document 2 does not need to install a working scaffold over the whole ceiling surface, a moving machine, such as an overhead crane, is required for the movement of a work stage, and there exists a problem that the cost concerning the lifting machine is large. there were.

  The present invention has been made in view of the above-described problems, and by adopting a construction method that does not use a scaffold or a lifting machine, the construction cost can be reduced and the construction period can be shortened. It aims to provide a method.

In order to achieve the above object, the ceiling transport mechanism according to the present invention is a ceiling transport mechanism for installing a ceiling block formed by dividing a ceiling constructed in a building, and fixedly supports the ceiling block. A fixed rail provided on the ceiling support frame for moving, a moving rail that is connectable in the extending direction of the fixed rail and can be moved up and down, an elevating means for moving the moving rail up and down, and moved to the moving rail And a traveling device provided so that the traveling device reciprocates between the moving rail and the fixed rail when the moving rail is connected to the extension line of the fixed rail.
Further, in the ceiling construction method according to the present invention, the ceiling support frame for fixing and supporting the ceiling constructed in the building, the fixed rail provided on the ceiling support frame, and connectable in the extending direction of the fixed rail A ceiling construction method in which a ceiling block formed by dividing a ceiling is arranged on a ceiling support frame, and the ceiling block is installed on the moving rail. A first step of fixing to the traveling device, a second step of raising the moving rail and connecting the moving rail on the extension line of the fixed rail, and moving the traveling device laterally along the moving rail and the fixed rail, And a third step of fixing to the ceiling support frame.
In the present invention, the fixed rail is previously installed on the ceiling support frame, the ceiling block is assembled on the ground floor, etc., and is fixed so that the ceiling block is suspended by the traveling device on the moving rail, and remains in that state. Raise the moving rail and stop it on the extension line of the fixed rail. Then, the traveling device is moved laterally from the moving rail to the fixed rail, and the ceiling block is fixed to the ceiling support frame and the previously installed ceiling block at a predetermined installation position. A ceiling can be constructed by sequentially installing a plurality of ceiling blocks in such a procedure.

In the ceiling transport mechanism according to the present invention, a plurality of fixed rails are arranged at a predetermined interval in the width direction orthogonal to the extending direction of the fixed rails, and the moving rails are connected by a long fixed member extending in the width direction. It is preferable.
In the present invention, a plurality of fixed rails and moving rails can be appropriately arranged according to the length of the ceiling block in the width direction, and the ceiling block can be moved to a predetermined installation position.

According to the ceiling transport mechanism and the construction method of the present invention, a fixed rail is installed in advance, a movable rail provided so as to be movable up and down is disposed on an extension line of the fixed rail, and the movable rail is fixed between the fixed rail and the movable rail. The ceiling can be constructed using a simple transport mechanism such as reciprocating the traveling device. This eliminates the need for a work scaffold that is disposed over the entire ceiling as in the prior art, reduces the time and labor required to assemble and disassemble the scaffold, and shortens the construction period.
And since it is the construction method of the ceiling from which a lifting apparatus, such as a temporary elevator and a lift, becomes unnecessary, and an expensive scaffold is also unnecessary, installation cost can be reduced.
In addition, even if there is a floor such as a spectator seat that protrudes toward the space on the intermediate floor like a large space building such as a theater, the ceiling assembled on the ground can be installed without interfering with the spectator seat. It can be moved to a location.
Furthermore, since the assembly work of the ceiling block can be performed on the floor surface such as the ground floor and the ceiling work does not need to be performed on the work scaffold, the work at high places can be reduced and the safety can be improved.

For example, it is assembled in a state where facility work or finishing work is performed on a floor surface F that forms a predetermined position on the ground floor (this position is referred to as an assembly position R1). This assembly position R1 is a position deviated from the ceiling support frame 4 in plan view, and is located below a moving rail 12 (described later) that moves up and down.
In FIG. 1, a state where the first suspended ceiling block 1 </ b> A is installed on the ceiling support frame 4 is shown.

Next, the configuration of the transport mechanism 10 will be described.
As shown in FIG. 1, the transport mechanism 10 is a moving mechanism for sequentially installing the suspended ceiling block 1A constituting the suspended ceiling 1 at a predetermined installation position, and moves the suspended ceiling block 1A up and down in the vertical direction. It is moved in the horizontal direction.

Specifically, the transport mechanism 10 is an extension of the fixed rails 11, 11,... And the fixed rails 11, 11,. The moving rails 12, 12,... That are connectable in the direction and can be moved up and down in the vertical direction, the lifting means 20 for lifting and lowering each moving rail 12, the fixed rail 11 and the moving rail 12 are connected. The trolley 13 (traveling device) is configured to be reciprocally movable between the fixed rail 11 and the moving rail 12.
The plurality of moving rails 12, 12,... Are connected by support beams 14 and 14 (long fixing members) extending in a direction orthogonal to each moving rail 12.

As shown in FIG. 2, each fixed rail 11 is made of, for example, a long steel material having a cross section of H type, I type, C type or the like, and is arranged in parallel in the width direction of the large space building 2 with a predetermined interval. Yes. In this embodiment, four fixed rails 11, 11,... Are provided.
Further, as shown in FIG. 3, the moving rail 12 is moved up and down by the elevating means 20 as described above, and is located on the extension line of the fixed rail 11 (that is, the height between the moving rail 12 and the fixed rail 11). The position stops at the same position).

As a configuration for stopping the moving rail 12, a stopper 11 </ b> A is provided on the end surface 11 a of the fixed rail 11. The stopper 11A is provided so as to protrude toward the moving rail 12 and is configured such that the upper end 12b of one of the rising moving rails 12 (on the fixed rail 11 side) comes into contact with the projecting lower surface 11b. As a result, the upward movement of the moving rail 12 is restricted, and the moving rail 12 can be arranged so as to be continuous on the extension line of the fixed rail 11. The stop position at this time is defined as a raised position H1.
When the moving rail 12 is at the raised position H <b> 1, the trolley 13 can be moved laterally between the moving rail 12 and the fixed rail 11. As described above, the moving rail 12 has the ascending position H1 and the position (the lifting position H2 (see FIG. 1)) where the suspended ceiling block 1A on the floor surface F (see FIG. 1) is suspended by the chain block 15 (described later). Moved up and down.

  As shown in FIG. 3, two trolleys 13 are provided for each fixed rail 11 (each moving rail 12). The trolley 13 includes a wheel 13a that sandwiches the moving rail 12 (fixed rail 11) from both sides, and the wheel 13a is fitted in a side groove 12b of the moving rail 12 (fixed rail 11) in a rollable state. The trolley 13 temporarily fixes the wheel 13a and the moving rail 12 with, for example, a pin member (not shown) so that the wheel 13a does not roll when the moving rail 12 moves up and down.

  A chain block 15 is attached to the trolley 13. The chain block 15 is provided with a hook 15a via a chain whose length can be adjusted. And this hook 15a is latched to the predetermined location of the suspended ceiling block 1A, and it fixes so that this suspended ceiling block 1A may become substantially horizontal.

  As shown in FIGS. 2 and 3, the support beam 14 is a long steel material such as H-shaped steel, for example, and has a configuration in which a plurality of moving rails 12, 12,. ing. That is, the support beam 14 is fixed in a state where the lower surface 14 b is placed on the upper end 12 a of the moving rail 12.

As shown in FIG. 3, the lifting means 20 includes a wire rope 21, a hoisting machine 22 that lifts and lowers the upper end 14 a of the support beam 14 with the wire rope 21, and first and second windings of the wire rope 21 as appropriate. The pulleys 23 and 24 are generally configured. The hoisting machine 22 is fixed to a predetermined location on the upper surface of the ceiling support frame 4. The first pulley 23 is fixed to the upper end 14 a of the support beam 14, and the second pulley 24 is fixed to the lower surface 5 a of the ceiling mount 5 located above the first pulley 23.
The wire rope 21 is wound from the hoisting machine 22 side in the order of the second pulley 24 and the first pulley 23, and the tip 21 a of the wire rope 21 is fixed to the lower surface 5 a of the ceiling mount 5.

  In this way, in the lifting / lowering means 20, the wire rope 21 that suspends the upper end 14 a of the support beam 14 is wound or sent out by the hoisting machine 22, so that the hoisting machines 22, 22,. By moving 14a up and down in the same direction at the same speed, the fixed suspended ceiling block 1A (moving rail 12) is moved up and down in the vertical direction while keeping its posture horizontal.

Next, a ceiling construction method in which the suspended ceiling block 1A is arranged at a predetermined suspended ceiling position using the transport mechanism 10 will be described based on the drawings.
First, as shown in FIG. 3, the trolley 13 on the moving rail 12 is fixed by appropriate fixing means (not shown) so as not to slide on the moving rail 12. Further, the suspended ceiling block 1A is assembled at the assembly position R1 (see FIG. 1) of the floor surface F.
And as shown in FIG. 1, each hoisting machine 22,22, ... is driven, the wire rope 21 is unwound, and the moving rail 12 is lifted up position H2 (position which can suspend the suspended ceiling block 1A in assembly position R1). Lower to stop. Then, a predetermined position of the suspended ceiling block 1A is fixed by the hook 15a of the chain block 15, the wire rope 21 is wound up by the hoisting machine 22, and the suspended ceiling block 1A is lifted together with the moving rail 12.

  Next, as shown in FIG. 3, when the upper end 12 a of the moving rail 12 comes into contact with the stopper 11 </ b> A provided on the end top surface 11 a of the fixed rail 11, the hoisting machine 22 stops. At this time, each moving rail 12 is arranged on an extension line of each fixed rail 11 at the rising position H1. Note that the rails 11 and 12 are preferably detachably connected by appropriate fixing means (not shown).

And the movement fixed state of the trolley 13 is cancelled | released, the trolley 13 is moved laterally with the suspended ceiling block 1A from the moving rail 12 to the fixed rail 11 side, and the suspended ceiling block 1A is moved to a predetermined installation position. The suspended ceiling block 1A arranged at a predetermined installation position is connected and fixed to the ceiling support frame 4 and the previously arranged suspended ceiling block 1A, and the hook 15a is removed from the suspended ceiling block 1A after the fixation is completed. When the suspended ceiling block 1A is fixed to the ceiling support frame 4 or the adjacent suspended ceiling block 1A, the attachment operation is performed while finely adjusting the attachment angle and height by the chain block 15.
In this way, the suspended ceiling 1 is constructed by sequentially feeding the suspended ceiling block 1A along the fixed rail 11 to the predetermined position.
In addition, since the fixed rail 11 is a structure which can remain in the attached state without disassembling even after construction of the suspended ceiling 1, it is possible to reduce labor and time for disassembling.

As described above, in the ceiling transport mechanism and construction method according to the present embodiment, the fixed rail 11 is installed in advance, the movable rail 12 provided so as to be movable up and down is arranged on the extension line of the fixed rail 11, and the movable rail The suspended ceiling 1 can be constructed using a simple transport mechanism in which the trolley 13 is reciprocated between the fixed rail 11 and the fixed rail 11. This eliminates the need for a work scaffold that is disposed over the entire ceiling as in the prior art, reduces the time and labor required to assemble and disassemble the scaffold, and shortens the construction period.
And since it is the construction method of the ceiling from which a lifting apparatus, such as a temporary elevator and a lift, becomes unnecessary, and an expensive scaffold is also unnecessary, installation cost can be reduced.
Moreover, even when there is a floor such as a spectator seat 2B protruding to the space side on the intermediate floor as in a large space building 2 such as a theater, the suspended ceiling block 1A assembled on the ground is used as the spectator seat 2B. It can be moved to the installation location of the suspended ceiling 1 without interfering with.
Furthermore, since the assembly work of the suspended ceiling block 1A can be performed on the floor surface F such as the ground floor and it is not necessary to perform the ceiling work on the work scaffold, the work at a high place can be reduced and the safety can be improved.

As mentioned above, although embodiment of the conveyance mechanism and construction method of the ceiling by this invention was described, this invention is not limited to said embodiment, In the range which does not deviate from the meaning, it can change suitably.
For example, in the present embodiment, the construction method of the suspended ceiling 1 is intended for a large space building 2 such as a theater where the spectator seat 2B protrudes into the space, but such a spectator seat 2B protrudes. It is not limited to the large space building 2 having a shape. For example, a large space building in which the plane from the floor surface F to the ceiling of the ground floor has the same shape may be used.
Further, in the present embodiment, four fixed rails 11 (moving rails 12) are provided, but the number is not limited to this number, and according to the length in the width direction of the suspended ceiling block 1A. What is necessary is just to install suitably.
Further, the specific configuration of the pulleys 23 and 24 of the lifting means 20, the fixing position of the hoisting machine 22, the size, the quantity, and the like are the shape and size of the large space building to be implemented, the position of the ceiling mount 5 The optimum design may be performed in consideration of construction conditions such as height.
Furthermore, in the present embodiment, the chain block 15 is attached to the trolley 13 so that the position and inclination of the suspended ceiling block 1A can be adjusted. For example, a hanging tool such as a wire or a chain can be used, It does not matter as a configuration in which the suspended ceiling block 1A is fixed with a bolt or the like.
