Description

TECHNICAL FIELD

[0001] The present invention relates to an elevator hoistway installed in each floor of a building and including a landing door, a door sill, a jamb, etc. for the ingress and egress of passengers or cargos, and a construction method thereof, and in detail, to an elevator hoistway and a construction method thereof, in which a door sill is combined with a jamb by installing an easily assembled and separated "inverted T" or "L" shaped separation plate between the jamb and the door sill, so that the door sill can be easily replaced without removing the mortar or concrete of a landing floor after a finishing work of the building (a mortar filling work of the landing floor). BACKGROUND

[0002] Generally, a high-rise building of six or more stories is installed with an elevator for moving or transporting passengers or cargos up and down by power. Also, a hoistway is installed in each floor of the building for the ingress and egress of passengers or cargos to the elevator car moving up and down.

[0003] The hoistway includes a landing door, a door sill, a jamb, etc. The door sill is installed in a horizontal direction to the floor (the floor of the elevator entrance) right below the landing door. Also, a plurality of door shoes of the landing door are slidably combined with a rail portion of the door sill, and move in a sliding manner along the door sill to open and close the entrance.

[0004] On the other hand, the elevator is installed in advance before the completion of the building, so as to transport building materials, etc. during the finishing work of each floor. Therefore, when the elevator is used to transport the building materials, etc., scratches, abrasions, or damages, etc. can easily occur on the surface of the door sill exposed to the outside, and thus a new product needs to be replaced after the completion of the building.

[0005] Figure 1 And Figure 2 is a sectional view showing a construction process of the hoistway of the prior art, Figure 3 is an enlarged view showing Figure 1 the door sill shown in FIG. 1.

[0006] Referring to Figures 1 to 3 the construction process of the hoistway of the prior art, a sill bracket 11 is first installed in the sill portion of the floor (the concrete floor) 1 of each floor of the building, and then a door sill 12 is welded and fixed to the upper portion thereof so as to conform to the level (fL) of each floor. Also, after a jamb 13 is fixed to the door sill 12, a landing door 14 is installed by door shoes 14a.

[0007] Next, as shown in Figure 1 , after the jamb 13 and the landing door 14 are installed, if the elevator related adjustment operation is completed, as shown in Figure 2As shown, the finishing work using the mortar is performed to fill the mortar between the door pocket 13 and the floor 1 of the building. That is, the space between the door pocket 13 and the floor 1 of the building is filled with the mortar finishing material 2, and the step difference between the floor 1 of the building and the door pocket 13 is eliminated, thereby completing the construction.

[0008] However, in the conventional lift platform, the door pocket 13 is installed and fixed to the door sill 12 through the bolt B of the first fixing portion 12a formed on one side of the door sill 12, and the lower portion of the door pocket 13 is covered with the mortar finishing material 2, so that the door sill 12 cannot be replaced without removing the mortar finishing material 2 at the time of replacement work.

[0009] As described above, in the conventional lift platform, since the door pocket 13 is combined with the door sill 12 through the bolt B, the door sill 12 can be replaced only by removing all of the building finishing materials such as the mortar finishing material 2, which has been previously constructed, at the time of replacement work of the door sill 12.

[0010] Therefore, in the conventional lift platform, the building finishing process such as the mortar finishing process is additionally performed after the replacement of the door sill 12, so that the replacement operation is complicated, the replacement cost and time are increased, the construction waste is increased, the environmental pollution is caused, the finishing work surface is not uniform, and the step difference of the lift floor occurs.

[0066] The technical features of the present application will be described in detail below with reference to the accompanying drawings.

[0067] Figure 4 is a sectional view briefly showing a lift platform for an elevator according to Embodiment 1 of the present application.

[0068] Referring to Figure 4 , the lift platform according to Embodiment 1 of the present application is installed at each floor of a building so as to be used in an elevator for going in and out of each floor, and basically includes a door pocket 13 installed at an upper portion of a floor ground (concrete ground) 1 of each floor and a floor door 14.

[0069] The door pocket 13, which is an outer door pocket installed at an entrance of the lift platform, is generally formed in a "T" shape, and one side portion thereof is fixed to a separation plate 23 through a bolt 24 or a nut and a bolt, wherein the separation plate 23 is installed at a lower portion of a door sill 22 in a separable manner so as to be combined with the floor door 14 to be slid.

[0070] Figure 5 is a perspective view showing Figure 4 the separation plate, Figure 6 is a perspective view showing Figure 5 a state in which the separation plate is fixed to the door pocket, Figure 7 is a sectional view showing Figure 5 a process in which the separation plate is inserted into the lower portion of the door sill.

[0071] Referring to Figures 5 to 7 , the separation plate 23 according to the present application is formed in an "L" shape, and includes a vertical portion 23a fixedly adhered to a lower side of the door pocket 13 through a bolt 24 (for example, an M8 bolt), and a horizontal portion 23b horizontally bent from a lower end portion of the vertical portion 23a and inserted into a gap g provided between a lower portion of the door sill 22 and a sill support 11.

[0072] The separation plate 23 can be formed of a metal material, for example, a stainless material, and a length thereof can be formed to be greater than a width of the entrance of the lift platform by about 600 mm or so. In addition, a length L1 of the vertical portion 23a can be about 23 to 25 mm, and a length of the horizontal portion 23b can be about 8 to 10 mm. That is, the separation plate 23 can be formed to correspond to a specification of the door sill 22.

[0073] Such a separation plate 23 is as Figure 5As shown, the vertical part 23a is fixed to the lower side of the door frame 13 by bolts 24 or bolts and nuts. The horizontal part 23b, which bends from the vertical part 23a, is not fixed to the door sill 22 by other fasteners, but is inserted into the gap g between the lower part of the door sill 22 and the sill bracket 11 (or the building floor 1).

[0074] Bolt 24 can be, for example, an M8 bolt, or an M8 nut and bolt can be used instead of an M8 bolt. This bolt 24 can be fitted to the vertical portion 23a of the separation plate 23. In this case, two bolts 24 can be connected along the length of the separation plate 23, and the gap between them can be formed to be about 30 to 150 mm wider than the entrance and exit of the lifting platform. According to the shape of the door frame 13, the fixed position of the door frame 13 is matched to create a larger gap.

[0075] Figure 8 It is shown Figure 4 The main cross-sectional view of the door sill is shown.

[0076] like Figure 7 and Figure 8 As shown, the door sill 22 of the present invention includes a track portion 22a, which is slidably engaged with the door guide shoe 14a of the landing door 14 to guide the landing door 14.

[0077] On one side of track section 22a ( Figure 8 The left side of the door sill 22 has a first fixing part 22b integrally formed, which presses and fixes the separation plate 23 inserted between the door sill 22 and the sill bracket 11 downward.

[0078] The first fixing part 22b can be configured to open to one side, i.e., towards the door frame 13, for example, with or Structural configuration. Furthermore, the lower part of the first fixing part 22b is higher than the lower part of the track part 22a, so as to form a gap of size t between them.

[0079] The step difference t between the lower surface of the first fixing part 22b and the lower surface of the track part 22a is equal to the distance from the upper surface of the sill support 11 fixed to the lower part of the door sill 22 to the lower surface of the first fixing part 22b. Furthermore, the step difference t between the lower part of the first fixing part 22b and the lower part of the track part 22a is formed to be the same as or greater than the thickness of the horizontal part 23b, so that the horizontal part 23b of the separating plate 23 can be inserted and joined between the lower part of the first fixing part 22b and the upper part of the sill support 11.

[0080] like Figure 7As shown, after the horizontal part 23b of the separation plate 23 enters the gap g formed between the lower part of the first fixing part 22b and the upper part of the sill support 11, that is, after entering the gap caused by the step difference t between the lower surface of the first fixing part 22b and the lower surface of the track part 22a, it is fixed between the sill 22 and the sill support 11 by means of the fixing force of the sill 22 fixed to the sill support 11.

[0081] On the other hand, on the other side of the track section 22a ( Figure 8 The second fixing part 22c is integrally formed on the right side of the door sill 22, and the second fixing part 22c fixes the door sill 22 to the upper part of the sill bracket 11 by means of fixing bolt 21.

[0082] The second fixing part 22c is as follows Figure 8 As shown, it can be constructed with a structure that opens to the downward side (in the direction of the sill support), for example, in the form of a "∩", or in the form of... Structure formation, in which, The structure has a horizontally bent snap-fit ​​piece in the downward-opening part so that the head of the fixing bolt 21 can snap into the downward direction.

[0083] On the other hand, although not shown, a cover (not shown) for protecting the door sill 22 may also be installed.

[0084] Figures 9 to 14 This is a cross-sectional view showing the construction process of the threshold of the present invention.

[0085] like Figure 9 As shown, the construction method of the lifting platform of the present invention firstly involves fixing and installing a sill bracket 11 on the sill of the building ground 1, and then installing a door frame 13 on the upper part of the building ground 1.

[0086] Next, after fixing the separation plate 23 to one side of the lower part of the door frame 13 with bolts 24, the door sill 22 is fixed to the upper part of the sill bracket 11 with fixing bolts 21.

[0087] The first fixing part 22b of the door sill 22 is fixed to the upper part of the sill bracket 11 by fixing bolts 21, so that the lower part is placed on the upper part of the horizontal part 23b of the separation plate 23 in an aligned state. Therefore, the horizontal part 23b of the separation plate 23 is fixed with strong fixing force between the first fixing part 22b of the door sill 22 and the sill bracket 11 by means of the fixing force generated by the fixing bolts 21.

[0088] Next, the building finishing work is carried out to complete the raising and lowering of the ground.

[0089] like Figure 9As shown, in the state where the lifting platform is installed, when the door sill 22 is replaced with a new product due to scratch, wear or damage, etc., the replacement method is as follows.

[0090] First, as shown in Figure 10 , the layer door 14 is separated from the door sill 22, and as shown in Figure 11 and Figure 12 , the fixing bolt 21 is loosened, and the door sill 22 is separated from the sill bracket 11.

[0091] Then, as shown in Figure 13 , in the same way as the construction method, the new door sill 22' to be replaced is placed on the upper part of the horizontal part 23b of the separation plate 23, and is fixed to the sill bracket 11 by the fixing bolt 21.

[0092] Then, as shown in Figure 14 , after the door sill 22 is installed, the door guide shoe 14a of the layer door 14 is combined inside the rail part 22a of the door sill 22, and the replacement of the door sill is completed.

[0093] As described above, in the lifting platform of the embodiment 1 of the present application, the door casing 13 and the door sill 22 are fixed by the separation plate 23 having the "L" shape structure which is easy to assemble and separate, so that when the door sill is replaced with a new product, even if the mortar or concrete of the lifting floor which is the finishing work of the ground of the lifting platform is not removed, the door sill can be selectively replaced simply.

[0094] Figure 15 is a sectional view showing a lifting platform for an elevator according to an embodiment 2 of the present application.

[0095] Referring to Figure 15 , the lifting platform of the embodiment 2 of the present application includes a door casing 13 and a layer door 14 installed on the upper part of the ground (concrete ground) 1 of each floor building, as shown in the embodiment 1.

[0096] The door casing 13, which is an outer door casing installed at the entrance of the lifting platform, is formed in a substantially "U" shape, and one side part is fixed to the separation plate 23 by a bolt b1 or a nut and bolt, wherein the separation plate 23 is installed at the lower part of the door sill 22 in which the layer door 14 is slidably combined, in a separable manner.

[0097] Figure 16 is a perspective view showing the separation plate as shown in Figure 15 , Figure 17 is a sectional view showing the process in which the separation plate as shown in Figure 15 is inserted into the lower part of the door sill.

[0098] Referring to Figure 16 and Figure 17The sectional plane of the separation plate 33 of the present application is formed in a substantially "inverted T" shape so as to be engaged in a latching manner toward the door pocket 13.

[0099] The separation plate 33 includes, for example, a vertical portion 331 which is fixed to the lower side of the door pocket 13 in close contact by a bolt b1 (for example, an M8 bolt), a horizontal portion 332 which is bent horizontally from the lower end portion of the vertical portion 331 to be engaged in a latching manner to the lower portion of the one side portion of the door sill 22, and a fixed portion 333 which is bent horizontally from the lower end portion of the vertical portion 331 in the direction opposite to the horizontal portion 332 to be inserted between the lower portion of the door pocket 13 and the plaster finish material 2.

[0100] The separation plate 33 is formed of the same aluminum material as the door sill 32, and does not cause a heterogeneous feeling with the door sill 32. Further, the length can be formed to be larger than the width of the entrance and exit of the lift platform by about 600 mm, the height L1 of the vertical portion 331 can be substantially 23 to 30 mm, and the length L2 of the horizontal portion 332 can be substantially 8 to 10 mm, according to the specifications of the door sill 32.

[0101] The vertical portion 331 is fixed to the lower side of the door pocket 13 by the bolt b1 or a bolt and a nut, and the horizontal portion 332 bent from the vertical portion 331 is formed with an engagement groove 332a in the upper portion for engagement with the engagement ridge 322b bent vertically downward at the end portion of the one side portion of the door sill 32. Further, the fixed portion 333 is bent horizontally from the lower end portion of the vertical portion 331 in the direction opposite to the horizontal portion 332 to be inserted between the lower portion of the door pocket 13 and the plaster finish material 2.

[0102] The bolt b1 can use an M8 bolt, or an M8 nut and a bolt can be used instead of the M8 bolt. The bolt b1 is fixed by being welded after being punched in the vertical portion 331 of the separation plate 33, and two bolts b1 can be welded and connected in the length direction of the separation plate 33, and the interval therebetween can be formed to be larger than the width of the entrance and exit of the lift platform by about 30 to 150 mm, according to the shape of the door pocket 13, to match the prescribed door pocket 13 fixing position to be spaced apart by a larger interval.

[0103] Figure 18 is a sectional view showing Figure 15 the door sill.

[0104] As Figure 17 and Figure 18 shown, the door sill 32 of the present application includes a rail portion 321 for insertion of the door guide shoe 14a of the layer door 14 to guide the layer door 14 in a sliding manner.

[0105] The rail portion 321 is formed in a substantially "inverted T" shape, and the door guide shoe 14a of the layer door 14 is inserted into the rail portion 321 to be guided in a sliding manner. Figure 18The first fixing portion 322 is integrally formed with the horizontal portion 332 of the separation plate 33 inserted between the threshold 32 and the threshold support 11.

[0106] As shown in FIG. 6, the first fixing portion 322 is formed in a structure open to one side direction (the door pocket 13 direction). For example, it can be formed in a structure as shown in FIG. 7 or 8. Figure 18 Moreover, a groove 322a is formed in the upper top surface of the first fixing portion 322 for insertion of the upper end portion of the vertical portion 331 of the separation plate 33, and a click ridge 322b is formed in the lower end portion bent downward, which is inserted into a click groove 332a formed in the horizontal portion 332 of the separation plate 33.

[0107] Moreover, as shown in FIG. 9, a step difference t is formed between the click ridge 322b and the lower surface of the rail portion 321, and the horizontal portion 332 is inserted between the click ridge 322b and the threshold support 11 and is clicked to the lower side of the rail portion 321 in the other side direction (the direction opposite to the door pocket 13). Figure 18 Figure 17

[0108] The step difference t between the click ridge 322b and the lower surface of the rail portion 321 is the same as the distance from the upper surface of the threshold support 11 to the click ridge 322b for fixing the lower portion of the threshold 32. Moreover, the step difference t between the lower portion of the click ridge 322b and the lower surface of the rail portion 321, i.e. the interval, can be formed to be the same as or slightly greater than the thickness of the horizontal portion 332 so that the horizontal portion 332 of the separation plate 33 is inserted between the click ridge 322b and the threshold support 11 and is combined.

[0109] After the horizontal portion 332 of the separation plate 33 is inserted into the gap formed between the lower portion of the first fixing portion 322 and the upper portion of the threshold support 11, i.e. the gap formed due to the step difference t between the click ridge 322b and the lower surface of the rail portion 321, it is fixed up and down between the threshold 32 and the threshold support 11 by the fixing force of the threshold 32 fixed to the threshold support 11 by the fixing bolt 21.

[0110] Moreover, as shown in FIG. 10, if the horizontal portion 332 is introduced between the lower portion of the first fixing portion 322 and the upper portion of the threshold support 11, the click ridge 322b formed in the lower portion of the first fixing portion 322 is inserted and clicked into the click groove 332a of the horizontal portion 332, so that the separation plate 33 is clicked to the threshold 32 in the one side direction and does not come off from the threshold 32 in the direction of the door pocket 13. Figure 17

[0111] As shown in FIG. 11, the second fixing portion 323 is integrally formed with the vertical portion 331 of the separation plate 33 inserted between the threshold 32 and the threshold support 11. Figure 18 ​​​​​As shown, on the other side of the track section 321 ( Figure 18 The second fixing part 323 is integrally formed on the right side of the door frame 11, wherein the second fixing part 323 uses the fixing bolt 31 as a medium to fix the door sill 32 to the upper part of the sill bracket 11.

[0115] like Figure 19 As shown, the construction method of the lifting platform of the present invention firstly involves fixing and installing a sill bracket 11 on the sill of the building ground 1, and then installing a door frame 13 on the upper part of the building ground 1.

[0116] Next, after fixing the separation plate 33 to one side of the lower part of the door frame 13 with bolt b1, the door sill 32 is fixed to the upper part of the sill bracket 11 with fixing bolt 31.

[0117] At this time, the door sill 32 is fixed to the upper part of the door sill bracket 11 by fixing bolts 31, so that the first fixing part 322 is positioned in a state aligned with the upper part of the horizontal part 332 of the separation plate 33. Therefore, the horizontal part 332 of the separation plate 33 is firmly fixed between the first fixing part 322 of the door sill 32 and the door sill bracket 11 by the fixing force generated by the fixing bolts 31.

[0118] Next, the building finishing work is carried out to complete the raising and lowering of the ground.

[0119] like Figure 19 As shown, when the door sill 32 is scratched, worn, or damaged and needs to be replaced with a new product after the lifting platform is installed, the replacement method is as follows.

[0120] First, such as Figure 20 As shown, after separating the floor door 14 from the door sill 32, as Figure 21 and Figure 22 As shown, loosen the fixing bolt 31 and separate the door sill 32 from the sill bracket 11.

[0121] Then, as Figure 23As shown, in the same way as the construction method, the new door sill 32' to be replaced is placed on the upper portion of the horizontal portion 332 of the separation plate 33, and is fixed to the sill bracket 11 by the fixing bolt 31.

[0122] Then, as shown in FIG. 6, if the door sill 32' is installed, the door guide shoe 14a of the landing door 14 is combined inside the rail portion 321 of the door sill 32', and the replacement of the door sill is completed. Figure 24

[0123] As described above, in the elevator hoistway of the embodiment 2 of the present application, the door casing 13 and the door sill 32 are fixed by the separation plate 33 of the "inverted T" shape structure which is easy to assemble and separate, so that when the door sill is replaced by a new product, even if the mortar or concrete of the hoistway floor which is subjected to the finishing work of the floor is not removed, the door sill can be optionally replaced.

[0124] In addition, in the elevator hoistway of the embodiment of the present application, the horizontal portion 332 of the separation plate 33 of the "inverted T" shape structure is engaged in the latching manner to the lower portion of the first fixing portion 322 of the door sill 32, so that the separation plate 33 can be prevented from being separated from the door sill 32.

[0125] In addition, in the elevator hoistway of the embodiment 2 of the present application, the separation plate 33 is formed in the "inverted T" shape structure, and the upper end portion of the vertical portion 331 of the separation plate 33 is combined in the structure which covers the upper portion of the first fixing portion 322 of the door sill 32, so that the separation plate 33 is not exposed to the outside (the upper portion of the door sill 32), and thus the architectural aesthetics can be improved.

[0126] In summary, the technical idea of the present application is described in the preferred embodiments, but the above preferred embodiments are only used for description and not for limitation. As described above, those skilled in the art can understand that within the scope of the technical idea of the present application, various embodiments can be realized by the combination of the embodiments of the present application.​
