In the present embodiment, the main rope tensioner mounting member 40 has a ring shape. However, the present invention is not limited to this, and the main rope tensioner 105 can be fixed thereto. If it is, it may be of another shape.

FIG. 7 is a partially cutaway plan view showing the structure of the main rope tensioner 105. As shown in the figure, the main rope tensioner 105 has a rectangular parallelepiped main body 50 having a hollow inside. ,
A tooth profile 52 provided on a tooth shaft 51 provided in an internal space of the main body 50 and one end side are engaged with a spring receiver 53 provided on an inner wall of the main body 50, and the other end side is engaged with a side edge of the tooth profile 52. A toothed spring 54 mounted on the toothed shaft 51 so as to be stopped, and a parent line receiving member 55 provided in the internal space of the main body 50 at a predetermined distance from the tip of the toothed shape 52.
And an auxiliary pulley 56 provided on the side of the master bracket receiving member 55 and on the side opposite to the direction in which the tooth spring is biased.
And an eyebolt 57 provided on the outer wall of the main body 50 on the side opposite to the side on which the main rope tensioning bracket 55 is provided, and a hook 58 connected to the eyebolt 57. In the figure, the dashed line indicates the rope 106.
Is shown.

The tooth profile 52 is rotatable clockwise from the position where the distance from the parent bracket receiving member 55 is the shortest, and
It is provided on the tooth shaft 51 so that it cannot rotate counterclockwise from this position. On the other hand, the tooth spring 53 is a linear spring, and urges the tooth 52 in the direction of arrow A. Here, the rope 106 is inserted into the position shown by the dashed line in the figure from the direction of the arrow B.
When the rope 106 is pulled in the direction of arrow C,
The tooth profile 52 rotates in the direction opposite to the arrow A, that is, clockwise. As a result, the distance between the tooth form 52 and the master bracket 54 is increased, and the rope 106 slides along the master bracket 54 in response to the force in the direction of arrow C. On the other hand, when the rope 106 is pulled in the direction opposite to the arrow C, the rope 1
The tooth profile 52 rotates counterclockwise due to friction with 06,
The distance between the tooth profile 52 and the parent bracket 54 is reduced, and the rope 106 is locked by being sandwiched between the tooth profile 52 and the parent bracket 54. Therefore, the rope 106 once pulled in the direction of arrow C is not returned in the opposite direction.

On the other hand, if the tooth profile 52 is forcibly rotated in the direction opposite to the arrow A to maintain the state where the distance between the tooth profile 52 and the parent bracket receiving member 54 is widened, the rope 106 operates. It is slid in any direction according to the force.

It should be noted that the main rope tensioner 105 is merely an example, and in the present invention, other known and arbitrary configurations of the main rope tensioner can be used instead.

FIG. 8 shows a state in which the log 101 is attached to the log 101, and the master tensioner 105 is fixed to the log 104. In the drawings, the one-dot chain line shows the rope 106 slidably supported by the pulley 21 of the log pulley clamp 102. As shown in FIG.

An upward pulling force is always applied to the rope 106 by the load of the cross rail 107 and the curing sheet 108, and the main rope tensioner 105 locks the upward sliding of the rope 106. Accordingly, the rope 106 is maintained in a tensioned state. On the other hand, according to the master rope tensioner 105, the downward movement of the rope 106 is free, so that the operator can pull the rope 106 downward by an arbitrary length.

The horizontal rail 107 is a single pipe whose length is slightly longer than the interval between the two logs 101. As shown in FIG. 9, single pipe clamps 70 are respectively mounted near both ends thereof. ing. On the upper surface of each single tube clamp 70, there are provided binding portions 71 each having a hole formed in a rectangular plate-like body.
Each of the ropes 106 supported by 2 is inserted and tied, so that the horizontal rail 107 is hung between the two logs 101 to be laid horizontally, and moves up and down in accordance with the operation of the rope 106.

The horizontal rail 107 does not necessarily have to be a single tube, but may be a single tube joined by a well-known joint. Further, the single pipe clamp 70 is not attached to the horizontal rail 107, and the rope 1 is attached to both ends of the horizontal rail 107.
06 may be directly linked.

The curing sheet 108 is, as shown in FIG.
The rectangular shape has a horizontal dimension slightly shorter than the length dimension of the horizontal rail 107 and a vertical dimension slightly shorter than a predetermined height position where the log pulley clamp 102 is provided. Holes are provided at regular intervals in the periphery of the curing sheet 108, and eyelets 80 are provided in the holes. The curing sheet 108 is made of a synthetic resin such as polyester, and has a flameproof property and a soundproof property according to a nearby environment.

The hanging means 109 is, as shown in FIG.
It comprises a stainless ring (ring-shaped member) 90 slidably mounted on the horizontal rail 107 and a rotating eggplant (curing sheet retaining member) 92 connected to the stainless ring 90 via a connection ring 91. . The rotary eggplant 92 has an annular portion 92a for connecting to the stainless steel ring 90, and a hook portion 92b for hooking the curing sheet 108. As shown in the figure, the hook portion 92b is formed by a spring or the like. It is opened and closed by the expansion and contraction of a pin 92c urged downward. Usually, the hook 92b is closed in an annular shape, and the pin 92c is forcibly retracted. Is put on the eyelets 80 at the upper end of the curing sheet 108, and the pin 92c is extended again, whereby
The eyelets 80 of the curing sheet 108 are hooked on the rotating eggplant 92. In this way, each eyelet 80 of the curing sheet 108 is hung by the plurality of suspending means 109, and the curing sheet 108 is hung on the horizontal rail 107.

In the present embodiment, the rotary eggplant 92 is connected to the stainless steel ring 90 via the connecting ring 91. However, the annular portion 92a of the rotary eggplant 92 is formed without using the connecting ring 91. It may be connected directly to the stainless steel ring 90.

The curing sheet 108 hung on the horizontal rail 107
As shown in FIG. 1, is attached to each log 101 with a string 81 at a position about one third of the vertical dimension from the lower end on both side edges. Accordingly, when the horizontal rail 108 is supported by the horizontal rail support member 30 of the log horizontal rail clamp 103, the curing sheet 108 is folded in three from the position fixed to each log 101. Become.

It should be noted that a log 10
The height position to be fixed to 1 is horizontal log clamp 1
03 in consideration of the height position to which the fixing sheet 03 should be fixed.
8 may be set appropriately so as not to drop on the ground.

At the lower end of the curing sheet 108, a log 82 as a weight is fixed by a string passed through an eyelet 80. The log 82 is cured by a wind or the like.
8 is provided in order to prevent the lower end of the curing sheet 108 from rolling up by resisting the buoyancy force generated in 8.

Hereinafter, a method of using the lifting gate 100 for demolition work curing according to the present embodiment will be described. As shown in FIG. 1, the horizontal rail 107 suspended between the logs 101 and suspended by the rope 106 rises and falls according to the operation of the rope 106. Therefore, when the worker pulls the rope 106 downward and raises the horizontal rail 107 to the vicinity of the pulley 103, the front side of the building 1 is cured by the curing sheet 108 suspended on the horizontal rail 107. Further, the rope 106 once pulled by the master rope tensioner 105 is locked against the upward pulling force, so that the rope 106 is not returned in the opposite direction, and
07 is maintained at a height near the pulley 103.

[0038] Thus, when the demolition work is interrupted,
Since no one other than the person concerned can enter the site, fires and accidents can be prevented beforehand, and when heavy equipment and trucks are stored inside the site, theft and the like can be prevented.
Further, even during the demolition work, privacy is ensured since the interior of the demolition building is not exposed to the road side, and dust and demolition members due to the demolition work can be prevented from scattering.

On the other hand, the unlocking of the main rope tensioner 105 is released, the rope 106 is sent out, and the horizontal beam 107 is supported on the horizontal beam receiving member 30 of the log horizontal beam clamp 103, whereby the disassembled member is removed. The front side of the building 1 can be opened for carrying out. As a result, as shown in FIG.
The member disassembled from above the horizontal rail 107 can be carried out to the truck 5 on the road by the heavy equipment 4 without removing the rail 8. The curing sheet 10 is located below the horizontal rail 107.
8, the scattering of dust and dismantled members can be minimized. In addition,
07 is lowered to an arbitrary height position to lock the main rope tensioner 105, and the horizontal beam 107 is maintained at an arbitrary height position and disassembled from above the horizontal beam 107 in the same manner as described above. The members can be carried out and the like, and the area below the horizontal rail 107 can be cured by the curing sheet 108. This is a particularly useful opening means when there is no space for stopping the truck 5 or the like for transporting dismantled members in the premises.

In a state where the horizontal rail 107 has been raised to the vicinity of the pulley 103, the log 82 as a weight is removed from the lower end of the curing sheet 108, and as shown in FIG. If collected, the space between the logs 101 can be easily opened. This allows
The heavy equipment 4, the truck 5, and the like can enter and exit from between the opened logs 101. This is a particularly useful opening means when the truck 5 or the like for transporting dismantled members on the premises can be stopped.

In the lifting gate 100 for demolition work curing according to the present embodiment, the log 82 is provided at the lower end of the curing sheet 108, but instead of the log 82, each of the lower ends of the curing sheet 108 is provided. By providing an appropriate weight for each eyelet 80, the curing sheet 108 can be opened without removing the weight.

In the present embodiment, the hanging means 109 composed of the stainless steel ring 90 and the rotating eggplant 92 is used.
Thus, the curing sheet 108 is hung on the horizontal rail 107, but when only the horizontal rail 107 is moved up and down and the curing sheet 108 does not need to be opened to the left and right,
For example, the curing sheet 108 may be hung on the horizontal rail 107 using a string or an S-shaped hook as a hanging means.
