The evacuation ladder installation structure according to a preferred embodiment of the present invention relates to an evacuation ladder installation structure which is installed to be moved to a lower floor through an opening 2 formed in an interlayer floor 1 of a building, and forms an opening 2. Bracket 210 is fixed to one side of the bottom surface (1) and one end of the wire 231 is connected to the wire drum rotatably installed on the bracket 210 so that the wire 231 is wound or unwinded Winch 200 including a 230, and the upper end is hinged to the bracket 210 so as to be rotatable, the lower end is connected to the other end of the wire 231, and constitutes a holding post 310 that is a longitudinal axis The plurality of pipes includes a ladder member 300 configured to extend in a telescopic type and to be lengthened or overlapped and shortened.

At this time, the telescopic type of the ladder member 300, the upper end is hinged to be rotatable to the bracket 210 and the lower end is connected to the other end of the wire 231, a pair of props (vertical axis) ( 310 each consists of a plurality of pipes (311, 313, 315) coupled so as to be sequentially overlapped, so that the wire 231 is wound or unwound by the wire drum 230 to the opening (2) Rotating inward and the length is shortened or rotated in the vertical downward direction of the bottom surface (1) is installed to be long.

That is, the evacuation ladder installation structure according to the present invention includes a bracket (210), the winch (winch) portion 200 and the ladder member 300.

The bracket 210 is fixedly installed at one side of the opening 2, which is a cut surface forming the opening 2 of the bottom surface 1.

The bracket 210 is a fixing frame to which the winch unit 200 and the ladder member 300 are coupled, and variously constituted by one or two or more members so that the winch unit 200 and the ladder member 300 may be coupled to each other. Can be.

The winch 200 winds or unwinds the wire 231 and allows the ladder member 300 to be received inside the opening 2 or below the opening 2, that is, vertically downward of the bottom surface 1. It is a means for adjusting the rotation and length of the ladder member 300 so that the ladder member 300 to the lower layer.

The winch 200 includes a wire drum 230 to which one end of the wire 231 is connected to wind or unwind the wire 231.

The wire drum 230 is installed to be rotatable on the bracket 210.

That is, the wire drum 230 is rotatably coupled to the bracket 210 so that the wire 231 can be wound or unwound by rotation.

The ladder member 300 is hinged to the bracket 210 so that the upper end is rotatable, and the lower end is connected to the other end of the wire 231 wound or unwound by the wire drum 230.

That is, when the wire 231 is released by the rotation of the wire drum 230, the ladder member 300 is rotated downward by gravity based on the upper end hinged to the bracket 210. Done.

At this time, the ladder member 300 includes a horizontal axis 320 which is a horizontal axis connecting between the pair of struts 310, which is a longitudinal axis (vertical axis) constituting the ladder and the strut 310, like a general ladder. .

However, the holding stand 310 is configured to be shorter or longer in length. That is, the support base 310 is composed of a telescopic type in which a plurality of pipes 311, 313, and 315 are sequentially overlapped and overlapped and fitted inside or outside. That is, the strut 310 is formed such that the length of the strut 310 may be lengthened or shortened by being coupled in a telescopic type.

For the telescopic type structure of the strut 310, the strut 310 is a portion in which each of the plurality of pipes is sequentially inserted inward or outward and overlapped to shorten the length, or each of the plurality of pipes overlaps inward. It is configured to protrude to be short and to be long in length.

The length adjustable base length 310 by the telescopic type structure described above is configured so that each of the plurality of pipes can be inserted inward or outward sequentially. This configuration is made possible by connecting a plurality of pipes whose diameters are sequentially smaller or larger so that they can overlap inward or outward sequentially in a range that does not deviate from each other.

Specifically, the upper pipe 311 hinged to the bracket 210, the intermediate pipe 315 is coupled to the inside or the outside, the middle pipe 315 is the upper end of the lower end of the upper pipe 311 The innermost pipe 311 is inserted into the inner side or the outer side of the uppermost pipe 311 or coupled to protrude from the inner side or the outer side without departing from the range.

Then, other pipes are similarly connected within a range not separated from the lower end of the intermediate pipe 315, and coupled to be inserted or protruded inward or outward within a range not separated from each other up to the lowermost pipe 313. do.

In this case, various configurations may be used to prevent the pipes 311, 313, and 315 from being separated from each other, but other pipes having a guide hole 316 formed in a lengthwise direction in the pipe and directly connected to the lower end thereof may be used. It can be simply configured by forming a guide pin 317 protruding to fit in the guide hole 316 of the.

At this time, the horizontal axis 320 is preferably coupled to each pipe so that the pipes are formed in the overlapping portion of each pipe in a state where the length of the support stand 310 is as long as possible to protrude out of the maximum.

A first rotary coupling part 312 is formed at an upper end of the support base 310 hinged to the bracket 210, that is, at an upper end of the uppermost pipe 311 among the pipes constituting the support base 310. The bracket 210 may have a hinge coupling part 213 hinged to the first rotation coupling part 312.

In addition, the other end of the wire 231 is connected to the lower end of the ladder member 300, it is connected to the last horizontal axis 320 connected to the lowermost pipe 315 of the pipes constituting the strut 310 desirable.

The position of the lower end of the ladder member 300 connected to the other end of the wire 231 is changed by the rotation of the wire drum 230 rotatably coupled to the bracket 210 by the above-described configuration.

That is, when the wire drum 230 is rotated to release the wire 231, the lower end of the ladder member 230 connected to the other end of the wire 231 by the hinge coupling of the ladder member 300 is applied to gravity. By this, the bottom surface 1 is rotated downward in the vertical direction.

At this time, the pipes constituting the strut 310 of the ladder member 300 also protrude out of each lower end so that the area overlapping inward by gravity is reduced, and the length of the strut 310 is lengthened.

In addition, when winding the wire 231 by rotating the wire drum 230 reversely, the lower end of the ladder member 230 connected to the other end of the wire 231 by the hinge coupling of the ladder member 300 is the opening. (2) It is rotated up to the inside, that is, to be in a horizontal direction with the bottom surface (1).

At this time, the pipes constituting the strut 310 of the ladder member 300 are also sequentially inwardly overlapped, so that the length of the strut 310 is shortened so that the ladder member ( 300) the whole can be stored.

The winch part 200 may further include a shaft 220.

At this time, the shaft 220 is rotatably coupled to the bracket 210, the wire drum 230 is coupled to the shaft 220 by the shaft is coupled to rotate together with the rotation of the shaft 220. .

That is, the shaft 220 is rotatably coupled to the bracket 210, and the wire drum 230 is coupled to the shaft 220 to be rotated together with the shaft 220.

The winch part 200 is coupled to the shaft 220 is rotated together with the shaft 220 and the clamp gear 240 and the one end is formed with a protrusion 241 of the projection form on the outer periphery of the bracket 210 Is coupled to the rotatable and the other end is formed with a locking projection 251 is engaged with the locking portion 241, when the locking portion 241 and the locking projection 251 is engaged the clamp gear 240 is fixed The stopper 250 may further include a stopper 250 installed to rotate the clamp gear 240 when the locking portion 241 and the locking protrusion 251 are separated.

That is, the winch part 200 further includes a clamp gear 240 and a stopper 250.

In this case, the clamp gear 240 is coupled to the shaft 220 to rotate together with the shaft 220 like the wire drum 230.

At this time, the engaging portion 241 of the projection shape is formed on the outer peripheral surface of the clamp gear 240. At this time, the locking portion 241 is formed in the form of a sawtooth to be engaged with the locking projection 251 of the stopper 250 to be described later.

That is, the clamp gear 240 is coupled to the shaft 220 together with the wire drum 230 so that the clamp gear 240 and the wire drum 230 and the shaft 220 are integrally rotated.

One end of the stopper 250 is rotatably coupled to the bracket 210, and the other end of the stopper 250 is installed to be engaged with the engaging portion 241 of the clamp gear 240.

That is, the stopper 250 is a means for fixing the clamp gear 240 to stop the rotation or to release the clamp gear so that the clamp gear 240 can be rotated. That is, the stopper 250 may engage the locking protrusion 251 with the locking portion 241 so that the clamp gear 240 is fixed without being rotated or the locking portion 241 and the locking protrusion 251. ) Is separated to allow the clamp gear 240 to rotate.

That is, when the locking protrusion 251 of the stopper 250 is separated from the locking portion 241 of the clamp gear 240, the clamp gear 240, the wire drum 230, and the shaft 220 are together. It becomes a rotatable state. On the contrary, when the locking projection 251 of the stopper 250 is engaged with the locking portion 241 of the clamp gear 240, the clamp gear 240 is in a state in which rotation is impossible by the stopper 250. The clamp gear 240, the wire drum 230, and the shaft 220 also become impossible to rotate.

That is, when the dropper 250 and the clamp gear 240 are engaged and fixed, the rotation of the wire drum 230 is stopped to fix the length of the wire 231, and the dropper 250 and the clamp are fixed. When the gear 240 is separated, the wire drum 230 may be rotated to change the length of the wire 231.

When the wire drum 230 is rotated to rotate the stopper 250 to engage the clamp gear 240 while the ladder member 300 is received inside the opening 2, the wire drum 230 is engaged. ) Is a sieve fixed to the ladder member 300 accommodated inside the opening 2 in a state where the rotation is stopped.

At this time, when the stopper 250 is rotated to separate the stopper 250 and the clamp gear 240, the ladder member 300 hinged to the bracket 210 by the weight of the ladder member 300. The lower end of the ladder member 300 is rotated in a downward direction based on the upper end of the), the wire 231 is released, the wire drum 230 is rotated and constitutes the strut 310 of the ladder member 300. The pipes 311, 313, and 315 may protrude in the downward direction, respectively, and lengthen.

At this time, the specific configuration of the stopper 250 is as follows (see Fig. 9).

At one end of the stopper 250, a rotation coupling part 253 is rotatably coupled to the bracket 210, and the other end thereof has a form that can be engaged with the locking part 241 of the clamp gear 240. A locking protrusion 251 is formed, and a handle manipulation unit 252 is formed to facilitate the rotation operation as the handle means.

The winch unit 200 is coupled to the shaft 220 and the brake disk 261 of the disk shape that is rotated with the shaft 220 and the brake disk through friction with both sides of the brake disk 261 The brake unit 260 may further include a brake lining 262 installed to control rotation of the 261.

That is, the winch unit 200 may further include a brake unit 260.

The brake unit 260 is a means for controlling the rotational speed of the shaft 220, the stopper 250 is a clamp gear 240 in a state that the ladder member 300 is accommodated inside the opening (2) Separated from the lower end of the ladder member 300 is rotated in the downward direction when the length of the strut 310 extends the length of the strut 310, that is, the pipe constituting the strut 310 ( 311, 313, and 315 respectively control the speed of protruding sequentially.

The brake unit 260 includes a brake disc 261 and a brake lining 262.

The brake disc 261 is coupled to the shaft 220 to rotate together with the shaft 220 in the form of a circular plate.

That is, the brake disc 261 is integrally rotated together with the shaft 220, the wire drum 230, and the clamp gear 240.

The brake lining 262 is installed to be in contact with both sides of the slave disk 261 without rotation and to be frictional.

That is, the brake lining 262 is coupled to the bracket 210 so as to overlap a part of the brake disc 261 with respect to the brake disc 261.

The brake unit 260 is the stopper 250 and the clamp gear 240 is separated and the ladder member 300 is rotated in a downward direction (specifically, the wire 231 wound on the wire drum 230) When the length of the ladder member 300 is loosened only enough to be rotated in the downward direction, and then the stopper 250 is engaged with the clamp gear 240 to fix the stopper 250, the clamp gear 240 When it is separated from the ladder member 300 is only rotated in the downward direction with little change in length) to apply a friction force to the brake disk 261 so that the wire drum 230 is not rotated.

At this time, the brake lining 262 adjusts the frictional force applied to the brake disc 261 and the length of the strut 310 of the ladder member 300 can be adjusted to a speed that extends in the downward direction.

In particular, the scaffold 330 to be described later is installed at the lower end of the ladder member 300, specifically, the lowermost pipe 313 of the pipes forming the support base 310, a person on the scaffold 330 In the case of climbing, the pipes protrude in the downward direction by the brake unit 260, respectively, so that the length of the support base 310 is extended downward to move a person. That is, in the case of the elderly who are difficult to go down the ladder it becomes a means that can move to the lower floor only by stepping on the scaffold 330. Detailed description of the scaffold 330 will be described later.

The brake unit 260 may further include a lining coupling shaft 263, a lining coupling plate 265, and an adjustment lever 266 (see FIG. 8).

The lining coupling shaft 263 is fixedly coupled to the bracket 210, and is installed so that an extension line of the brake disc 261 may cross.

The lining coupling plate 265 is coupled to the lining coupling shaft 263 to be disposed on one side and the other side of the brake disc 261, respectively. In this case, the lining coupling plate 265 forms a pair, one on each side and the other on the basis of the brake disc 261, each of which is installed symmetrically so that a portion overlaps with the brake disc 261.

In this case, each of the pair of lining coupling plate 265 is coupled to the brake lining 262 in close contact with the brake disc 261 to perform a brake function. That is, the brake linings 262 are respectively coupled to portions of the pair of lining coupling plates 265 that overlap with the brake discs 261, so that the combined brake linings 262 are the brake discs 261. To be in close contact with both sides and to perform the brake function.

The control lever 266 adjusts the degree of contact between the lining coupling plate 265 and the brake disc 261 so that the brake lining 262 coupled to the brake disc 261 is in contact with the friction disc 261 Is a means to adjust the degree of

That is, the deceleration degree of the brake disc 261 can be adjusted by the operation of the control lever 266.

Specifically, the control lever 266 is coupled to the bracket 210, one end portion of the lining coupling plate disposed on one side of the bracket 210 and the brake disk 261 and penetrates the bracket 210 ( 265 are coupled to move between.

This coupling structure may be implemented by installing one side of the control lever 266 is screwed to the bracket 210 to be reciprocated by rotation. In addition, it is natural that the reciprocating mounting structure of the control lever 266 may be applied to various methods used in the art.

That is, by operating the control lever 266 (for example, the operation to rotate the control lever clockwise) lining coupling plate 265, one end of the control lever 266 is disposed on one side of the brake disc 261. ) Is moved toward the brake disc 261, the adhesion between the pair of lining coupling plate 265 and the brake disc 261 is increased, a large friction force is generated between the two.

At this time, the brake coupling plate 265 and the brake disc 261 are both plate-shaped, made of a material that can be bent within a certain range will be capable of the brake operation.

In addition, when one end of the control lever 266 is moved in a direction away from the brake disc 261 by operating the control lever 266 reversely (for example, to rotate it counterclockwise), the pair The adhesion between the lining coupler plate 265 and the brake disc 261 becomes small, so that a small friction force is generated between the two.

In this case, the above operation may be effectively performed by inserting an elastic body 264 such as a spring between the pair of lining coupling plates 265.

At this time, one of the pair of lining coupling plate 265 is disposed on one side of the brake disk 261, that is, the lining coupling plate 265 adjacent to the bracket 210 is movable to the lining coupling shaft 263 The lining coupling plate 265 disposed on the other side of the brake disc 261 may be installed to be fixed.

That is, when the lining coupling plate 265 disposed on one side of the brake disc 261 is pushed toward the brake disc 261 by the operation of the control lever 266, the brake disc 261 is bent to the opposite side and the pair It is in close contact with the brake lining 262 coupled to the lining coupling plate 265 of each.

That is, when the clamp gear 240 and the stopper 250 are separated, the support base 310 of the ladder member 300 faces downward of the bottom surface 1, and the support base 310 is moved by gravity. The wire 231 connected to the lowermost pipe 313 constituting the strut 310 of the ladder member 300 is released by the rotation of the wire drum 230 so that the pipes constituting the protruding downwardly extend. do.

At this time, by controlling the brake unit 261 and the brake lining 262 by the operation of the brake unit 160, the shaft 220, the wire drum 230, the clamp gear 240 and the brake disc 261 You can adjust the rotation speed of). That is, by adjusting the rotational speed of the wire drum 230 by adjusting the speed of the wire 231 is released from the wire drum 230, it is to control the speed at which the support stand 310 extends downward.

As a result, only the pedestal 330 which is hinged to the lowermost pipe 313 or the lowermost pipe 313 constituting the strut 310 of the ladder member 300 may be lifted by the prop. 310 slowly stretches downwards to allow people to move downstairs. At this time, after the first person moves downstairs, the next people directly descend down the ladder member 300 connected to the downstairs. This is to ensure that people who are difficult to go down the ladder such as the elderly in an emergency evacuation situation can be safely evacuated downstairs first, and then the next person can directly descend the ladder.

The bracket 210 may be composed of one member or two to three members.

That is, the bracket 210 may include a main bracket 211, a first sub bracket 215, and a second sub bracket 217.

The main bracket 211 is a fixing frame for fixing the winch part 200 to the side surface of the opening 2, and the first sub bracket 215 and the second sub bracket 217 are the main bracket 211. To perform the function of the auxiliary frame to be coupled to the various components constituting the winch 200.

Referring to FIGS. 2 and 12, the coupling relationship between the winch unit 200 will be described as follows.

(2) is opened, and then the stopper 250 is rotated to separate the stopper 150 and the clamp gear 140 so that the ladder member 300 stored in the opening 2 is bottomed (1). Rotate in the downward direction. At this time, the scaffold 330 is rotated in the vertical direction with the support base 310 so that the user (especially the elderly) rises on the scaffold 330. At this time, the control lever 266 is preferably adjusted so that the brake lining 262 is in close contact with the brake disk 161.

After the user climbs on the footrest 330, the control lever 266 is adjusted to appropriately adjust the rotational speed of the brake disc 261 by the brake lining 262 so that the user who climbs on the footrest is below. Allow to move to the floor.

Subsequent users ride directly on the elongated ladder element 300 and move to the lower layer.

When the ladder member 300 is accommodated in the opening 2 again, the pipes constituting the props are rotated by rotating the shaft handle 270 reversely so that the wire 231 is wound around the wire drum 230. By overlapping, the length of the ladder member 300 is shortened, and the ladder member 300 itself is rotated and received inside the opening 2. Thereafter, the stopper 250 and the clamp gear 240 engage with each other to stop the rotation of the shaft 220, and then rotate the upper cover 100a downward to cover the opening 2. At this time, the lower cover (100b) is rotated to the upper side in conjunction with the operation to rotate the upper cover (100a) down.
