As shown in fig. 1, two through holes arranged up and down are opened in the right-side second decorative panel 20 to serve as a first mounting position 210 and a second mounting position 220, respectively. As shown in fig. 2, the side skeleton portion further has a support portion 211. The first mounting position 210 and the second mounting position 220 correspond to the two support portions 211 in fig. 2, respectively. In order not to affect the appearance of the elevator door pocket, the first mounting location 210 and the second mounting location 220 may be covered with a decorative cover plate, not shown, after the installation of the elevator door pocket is completed, so that the support portion 211 is not visible.

In fig. 2, the right second decorative panel 20 is attached to the side skeleton portion via two upper and lower support portions 211. The number of the support portions 211 is not limited, and two support portions are preferably arranged vertically.

The support portion 211 may be a substantially rectangular plate member made of metal, and at least the support portion 211 located above is provided with a through hole 2110, an adjustment hole 2111, and a screw hole 2112. Preferably, all the supporting portions 211 are provided with a through hole 2110, an adjustment hole 2111 and a screw hole 2112.

The through hole 2110 and the internally threaded adjustment hole 2111 are located at substantially the center of the support portion 211. The screw hole 2112 is located at the front side edge of the support portion 211 and is internally threaded. The through holes 2110 are used to be engaged with expansion bolts (not shown), and in particular, are fixed into the wall body through the through holes 2110 using the expansion bolts, so that the support portion 211 can be fixed to the wall body. The adjustment hole 2111 is for threaded engagement with an adjustment bolt (not shown). The function of the adjusting screw needs to be explained in particular here: in the process of installing the elevator door pocket to the wall body using the expansion bolts, after one of the upper and lower expansion bolts is fixed to the wall body, the door pocket is usually warped due to the tolerance between the wall surface and the door pocket when the other is fixed, and in this case, the adjustment is very troublesome. And through the setting of adjusting bolt, only need rotate this adjusting bolt, the top portion top of adjusting bolt is on the wall, and the adjusting hole can outwards remove along with the screw-thread fit with adjusting bolt this moment to adjust the door pocket to a position that neither warp also fully fixed very easily. The screw holes 2112 are adapted to engage with the mounting bolts a. The support portion 211 can be attached to the front-rear extending side portion 110 by the engagement of the bolt a and the screw hole 2112. When the right second decorative panel 20 has been attached to the support portion 211, the right second decorative panel 20 can be attached to the front-rear extending side portion 110 (i.e., to the right side skeleton portion) via the support portion 211.

In the installation process, when the adjustment bolt engaged in the adjustment hole 2111 abuts against the wall, the support portion 211 having the adjustment hole 2111 can be moved a certain distance on the bolt by rotating the adjustment bolt clockwise or counterclockwise, thereby achieving fine adjustment of the distance of the support portion 211 with respect to the wall. For example, the position of the support portion 211 relative to the wall may be adjusted by adjusting the adjustment holes 2111 and the adjustment bolts before the support portion 211 is fixed to the wall using the expansion bolts. Therefore, the adjustment holes 2111 and the corresponding adjustment bolts can be regarded as position adjustment portions for adjusting the attachment positions of the side skeleton portions (more specifically, the support portions 211) with respect to the wall body in the left-right direction.

In the state shown in fig. 1, the through hole 2110 and the adjustment hole 2111 of the support portion 211 may be exposed from the through hole, which is the first mounting position 210 or the second mounting position 220, so that the right second decorative panel 20 can be mounted to the wall body via the through hole 2110.

The upper edge of the right second decorative panel 20 is used for mounting the upper second decorative panel 40. A plurality of screw holes 2121 (two in fig. 2) are provided at the upper edge, and screw holes 401 corresponding to the screw holes 2121 are provided near the right side edge of the upper second decorative panel 40. The upper second decorative panel 40 can be attached to the right second decorative panel 20 by screwing the bolts a into the screw holes 401 and the corresponding screw holes 2121. In a modification of the present embodiment, the screw hole 401 may also be replaced with a through hole.

The left edge of the right and left extending portions 11 is provided with a front and rear extending side portion 110 extending rearward. The front-rear extending side portion 110 may be formed integrally with the left and right extending portions 11, or may be formed by connecting a separate member to the left edge of the left and right extending portions 11 by, for example, screwing, bonding, or caulking.

The front-rear extending side portion 110 is provided with two slots 111 arranged vertically. The slot length direction of the slot hole 111 is parallel or approximately parallel to the front-rear direction. The position of the upper slot hole 111 corresponds to the screw hole 2112 of the upper support portion 211, and the position of the lower slot hole 111 corresponds to the screw hole 2112 of the lower support portion 211.

When the front-rear extending side portion 110 and the support portion 211 are attached together, the bolts a are first engaged into the screw holes 2112 through the slot holes 111, and then the positional relationship in the front-rear direction between the front-rear extending side portion 110 and the support portion 211 is adjusted within the range of the slot length of the slot holes 111 without tightening the bolts a, and when the bolts a are tightened after the adjustment is made, the attachment of the front-rear extending side portion 110 and the support portion 211 can be achieved. The bolt a and the groove hole 111 correspond to an example of a side position adjustment portion that adjusts the attachment position of the longitudinal decorative portion in the front-rear direction in the present embodiment, and the screw hole 2112 is used to engage with the side position adjustment portion. As shown in fig. 2, two upper and lower lateral position adjusting portions are provided on the right side of the skeleton portion.

The right side edge of the front-rear extending upper portion 32 is provided with a groove hole 321 corresponding to the screw hole 401 near the right front side corner of the upper second decorative panel 40. The slot length direction of the slot hole 321 is parallel or approximately parallel to the front-rear direction. The upper second decorative panel 40 is attached to the front-rear extending upper portion 32 through a screw hole 401 near the right front side corner portion.

When the front-rear extension upper portion 32 and the upper second decorative plate 40 are attached to each other, the bolt a is first engaged into the screw hole 401 near the right front corner of the upper second decorative plate 40 through the slot hole 321, and then the positional relationship in the front-rear direction between the front-rear extension upper portion 32 and the upper second decorative plate 40 is adjusted within the range of the slot length of the slot hole 321 without fastening the bolt a, and the bolt a is tightened after the adjustment is made, whereby the attachment of the front-rear extension upper portion 32 and the upper second decorative plate 40 can be achieved. The bolt a and the groove hole 321 correspond to an example of an upper side position adjustment portion that adjusts the attachment position of the lateral decoration portion in the front-rear direction in the present embodiment, and the screw hole 401 is used to engage with the side position adjustment portion. As shown in fig. 2, one upper position adjustment portion is provided on the right side of the longitudinally extending upper portion 32.

A lateral trim strip C as an example of the upper decorative portion front-rear extending portion of the present embodiment is also shown below the front-rear extending upper portion 32 in fig. 2. The lateral trim strip C may be a portion of the lower edge of the upper first trim panel 30 extending rearward, or may be a separate trim strip fixed to the lower edge of the upper first trim panel 30 by means of adhesion or the like. A channel-shaped structure extending in the left-right direction may be formed between the lateral trim strip C and the front-rear extending upper portion 32. During the installation operation, the upper second decorative panel 40 can be easily inserted into the channel structure to facilitate temporary positioning of the upper second decorative panel 40 before bolt fastening.

The longitudinal trim strip B as an example of the side decorative portion front-rear extension of the present embodiment is also shown on the left side (i.e., the side away from the wall) of the front-rear extension side portion 110 in fig. 2. The longitudinal trim strip B may be a portion of the left edge of the right first decorative panel 10 extending rearward, or may be a separate trim strip fixed to the left edge of the right first decorative panel 10 by means of adhesion or the like. A channel-shaped structure extending in the up-down direction may be formed between the longitudinal trim strip B and the front-rear extending side portion 110. The right second decorative panel 20 can be easily inserted into the channel structure during the installation operation to facilitate temporary positioning of the right second decorative panel 20 prior to bolt fastening. Here, the term "temporary positioning of the right second decorative panel 20" includes both the case where the right second decorative panel 20 is temporarily positioned with respect to the left and right extending portions 11 in the case where the left and right extending portions 11 are fixed to the wall body, and the case where the left and right extending portions 11 are temporarily positioned with respect to the right second decorative panel 20 in the case where the right second decorative panel 20 is fixed to the wall body by the support portion 211.

Note that the provision of the longitudinal trim strips B and the lateral trim strips C is not essential. In the modification of the present embodiment, it is possible to include only either one of the longitudinal trim strips B and the lateral trim strips C, or none of the longitudinal trim strips B and the lateral trim strips C.

In the left and right extending portions of the right pillar portion, the fireproof sheathing board 60 is disposed between the left and right extending portions 11 in the skeleton portion and the wall body. In the front-rear extension portion of the right pillar portion, the fire-retardant sheathing panel 60 is inserted into a channel structure formed between the longitudinal trim B and the front-rear extension side portion 110, and is fixed to the wall body by a support portion 211 shown in fig. 2. Here, the right second decorative panel 20 may be provided on the left side of the fire liner 60, or the fire liner 60 may be used instead of the right second decorative panel 20. The right second trim panel 20 is replaced by a fire liner 60 as shown in figure 3.

At the front end portion and the rear end portion of the front-rear extending portion of the right pillar portion, there are provided fire-retardant rubber strips 50. More specifically, in the front-rear extending portion of the right pillar portion, the flameproof rubber strip 50 at the front end portion is located between the front end portion of the flameproof lining panel 60 and the left-right extending portion 11, and the flameproof rubber strip 50 at the rear end portion is located between the rear end portion of the flameproof lining panel 60 and the elevator door 1.

Both left and right ends of the left and right extending portions 11 are bent to the front side to form a protruding structure, thereby forming a U-shaped channel section capable of surrounding the right first decorative panel 10 from the left, right and rear sides in the horizontal sectional view shown in fig. 3. In the installation process, the left and right extending parts 11 with the U-shaped groove sections can be used for conveniently clamping the first decorative plate 10 on the right side in the U-shaped grooves of the left and right extending parts 11, so that the decorative plates can be further conveniently and fixedly installed.

For better fixing of the fire-blocking lining 60, the fire-blocking strip 50 and the longitudinal trim strip B, fixing means can also be provided which are able to form a channel-like structure with the front-rear-extending side 110, like that shown in fig. 3. The fixing member may be made of a metal material and formed as a part of a framework portion of the elevator door pocket. The fire-retardant rubber strips 50 and the front end portions of the fire-retardant patch 60 may be fitted into the channel structure formed by the fixing member and the front-rear extending side portions 110, and the longitudinal trim strips B may be fitted to the side of the fixing member opposite to the wall body (i.e., the inner side in the left-right direction).

Similarly to the case of fig. 3, a fire protection sheathing panel 60 may be inserted into the channel structure formed between the lateral trim strip C and the front-rear extension upper portion 32, and the fire protection sheathing panel 60 is fixed between the upper second decorative panel 40 and the wall body. Or the fire-blocking liner 60 may be used in place of the upper second decorative panel 40. A fire-resistant rubber strip 50 may be provided between the front end portion of the fire-resistant lining plate 60 and the vertically extending portion 31, and a fire-resistant rubber strip 50 may be provided between the rear end portion of the fire-resistant lining plate 60 and the elevator door 1.

Fig. 4 shows a layout in which the fireproof rubber strips 50 are provided at the boundary positions between the left and right extending portions and the front and rear extending portions of the elevator door pocket and the boundary positions between the rear end portion of the elevator door pocket and the elevator door 1, and the fireproof lining boards 60 are provided between the framework portion and the wall body of the elevator door pocket. For ease of viewing, elements other than the fire-blocking strip 50 and fire-blocking patch 60 are omitted from FIG. 4. The orientation in fig. 4 corresponds to fig. 2.

The fire-resistant lining 60 is made of a non-flammable material, and the fire-resistant rubber strip 50 is made of a material that can expand 15 to 50 times in case of fire. In the event of a fire, the fire-retardant sheathing panel 60 and the metal-made skeleton portion do not support combustion. The fire-proof rubber strip 50 can isolate the air circulation inside and outside the elevator door 1 after expanding in case of fire. Therefore, the modification shown in fig. 3 and 4 has a good fire-proof function, and particularly, can effectively prevent the elevator door 1 from becoming a passageway for the spread of fire between floors.

The elevator door pocket according to the present embodiment provides a framework structure that is easy to install and allows the positional relationship of the framework with respect to the wall to be flexibly adjusted in the left-right direction and the front-rear direction during installation by the side position adjusting portion and the upper side position adjusting portion.
