Description

[0001] Elevator anti-flood apparatus for construction [

The present invention relates to an elevator immersion prevention apparatus for a building, and more particularly, to an elevation immersion prevention apparatus for a building, which prevents inflow of a large amount of rainwater into an elevator gate installed in a rainy season building, will be.

Generally, an elevator installed in a building is composed of a complicated electric control device and a mechanical device as a moving means for moving each floor conveniently and quickly.

Such an elevator is not equipped with a device capable of blocking the inflow of rainwater. Therefore, there is a problem in that when the rainwater flows into the low-floor portion or the basement of the building located in the low-lying area in the rainy season with a large amount of rainfall, it is flooded by the rainwater flowing into the elevator.

In addition, in order to prevent flooding of the elevator, a sand bag is stacked in front of the elevator gate to temporarily block the rain water, but it is very difficult to block the rainwater flowing into the gap between the sand bag and the sidewall of the gate, There was a problem that when suddenly blowing, it flooded before the sand bag was built.

In view of these problems, in the prior art 1 (Patent Document 1), a technique has been proposed in which rainwater is blocked by raising a flooding stepped staircase provided in a staircase storage room formed on the floor of an elevator gate with an elevating cylinder.

However, in the prior art 1, there is no waterproof countermeasure against the sliding surface between the immersion step and the inner wall of the staircase compartment. Therefore, the rainwater is infiltrated into the fine gap and the staircase storage chamber and the lifting cylinder are flooded.

In the prior art 1, since a pneumatic cylinder using power is used for waterproofing the side wall of the elevator passenger gate, there is a problem that the occupied space is large during installation and the construction cost is greatly increased, and the compressed air required for driving the pneumatic cylinder is supplied (Air compressors, pneumatic valves, piping, etc.) for the installation.

As another example, in the prior art 2 (Patent Document 2), it has been proposed that the rain shielding plate installed on the floor of the elevator gate is constructed of a triangle by a man power to block rainwater.

However, the conventional art 2 does not have a structure for blocking the gap between the side wall of the elevator gate and the rain shielding plate. However, since silicone is sprayed here to waterproof it, it is difficult to cut rainwater quickly due to time required for silicon hardening , Silicon was put on the sidewalls of the gate, which made it difficult to remove silicon.

In the prior art 2, the lower end portion of the rainwater shielding plate is made to be waterproof by the contact between the rubber shield and the rainwater shielding plate. However, when the rainwater shielding plate is slightly moved, there is a problem in that the rainwater shielding plate and the rubber bar are leaked by spreading.

In addition, both of the prior art 1 and the conventional art 2 are applicable only when the side walls are facing each other on the left and right sides.

When the rainwater 200 flows in the state in which the side order plate 40 and the front water level plate 30 are raised and the folding riser 90 and the tread plates 100 and 110 are assembled as described above, And is shielded by the front level plate 30 and the side level plate 40 as described above to protect the elevator gate 20.

Particularly, the rubber side plate 33 is sandwiched between the wall surface 24 and the wall flange 44, between the bottom surface 22 and the bottom flange 32, 42 and between the corner flanges 34, 36, (61), (62), (67) and (68) and the rubber base plates (63) and (69) function to prevent leakage through this portion.

The process of storing the front water level plate 30 and the side water level plate 40 into the storage chambers 26 and 28 in order to prevent the inconvenience of passage when the rainwater 200 escapes and is normalized, When the support plate 95 is lifted in a "Z" shape with the lock pin 120 detached after separating the support plate 110 from the folding riser 90 and the reinforcing ribs 33, The slide pins 93p and 94p move along the guide slots 93 and 94 from the lower latching jaws 93a and 94a to the upper latching jaw 93u 94u.

At this time, the center of the pin hole 95h formed in the support plate 95 coincides with the center of the upper positioning hole 90a formed in the foldable riser 90, and the lock pin 120 which has been separated is inserted into the pin hole 95h When inserted into the positioning hole 90a, the support plate 95 is held in the raised position.

The folding riser 90 is then horizontally rotated about the vertical hinge 80 to be folded in an overlapping manner on the front level plate 30 and then the insert bolt 52 is separated from the embedding nut 50 and the flange bolts 56 And the nuts 54 are removed and then the bottom covers 26c and 28c are lifted and separated, the compartments 26 and 28 are opened.

When the front level plate 30 is rotated by the rotary arm 37 in a state in which the storage chambers 26 and 28 are opened with the horizontal hinge 70 as the center and the bottom surface 22 is laid down And the front level plate 30 enters the storage chamber 26 and the left and right side level plates 40 are also laid down by the rotary cam 47 toward the bottom surface 22 about the horizontal hinge 76 The side order plate 40 also enters the accommodating chamber 28. As shown in Fig.

The tread plates 100 and 110 are then inserted into the remaining empty space of the storage chamber 26 in which the front surface water level plate 30 is housed and the storage chambers 26 and 28 are closed by using the bottom covers 26c and 28c The elastic protrusion 132 formed on the protective cap 130 is inserted into the screw hole 51 formed in the recessed nut 50 and the head 134 formed on the protective cap 130 It is possible to prevent foreign matter from flowing into the threaded hole 51 of the buried nut 50 by closely contacting the wall 24 and the bottom surface 22.
