The sealing strip 7 of the present invention is optionally made of a material having elasticity such as a rubber material.

Fig. 6 shows a trim panel 4 that can be mated with the outer post mechanism of fig. 1-4. The decorative plate 4 is preferably made of an aluminum alloy which is light and not easily corroded, but other corrosion-resistant materials can be selected. Referring to fig. 6, the trim panel 4 has a sealing surface 41 and a waterproof surface 42. The sealing surface 41 is adapted to abut against the outer surface of the corner of the elevator shaft 6. For example, in the elevator shaft 6 shown in fig. 1 and 2, the sealing surface 41 of the decorative plate 4 has a planar shape. In addition, for elevator shafts 6 whose outer side faces are in an arc-shaped or polygonal configuration, the sealing surface 41 can be correspondingly replaced with a shape matching therewith.

Flashing surface 42 is arranged obliquely with respect to sealing surface 41. The sealing surface 41 and the waterproofing surface 42 intersect at the top to form a male joint having a thin-walled structure. The bottom of decorative board 4 is formed with the female joint portion that has groove structure and shape and male joint portion matching for decorative board 4 can be followed and is aimed at and peg graft each other after vertical insertion two adjacent outer column mechanism's the sealed slot portion. The female engagement portion is preferably provided on the side of the bottom of the decorative panel 4 near the sealing surface 41.

Preferably, the waterproof surface 42 and the sealing surface 41 form an angle θ of 1 ° to 13 °, for example, angles of 1 °, 5 °, 8 °, 10 °, and 13 °. After the rainwater falls on the surface of the decorative plate 4, the waterproof surface 42 can quickly guide the water obliquely, and the water is guided out from the decorative plate 4. This can prevent foreign matter such as rainwater from accumulating on the decorative panel 4 to form stains, thereby affecting the appearance of the decorative panel 4.

In the embodiment of fig. 6, the male engagement portion is formed as a snap strip 44 projecting upwardly from the top of the trim panel 4. In other embodiments, the male engagement portion may also be formed by the area where the sealing surface 41 and the waterproofing surface 42 intersect.

The trim panel 4 has a trim panel bottom wall 47 at its bottom connecting the sealing surface 41 and the waterproof surface 42. The trim panel bottom wall 47, the sealing surface 41, and the waterproof surface 42 collectively define the interior cavity 43 of the trim panel 4. The inner cavity 43 is optionally filled with a material for any one of heat preservation, heat insulation, sound insulation and fire resistance according to the installation environment of the elevator, so that the decorative plate 4 (the elevator) has good heat preservation, sound insulation and fire resistance functions.

Alternatively, the waterproof surface 42 protrudes downward from the lower surface of the decorative panel 4 to form a dripping protrusion 46. The rainwater drops on the dripping projection 46 and directly drops on the ground without flowing along the decorative plate bottom wall 47 toward the sealing surface 41, or stays on the dripping projection 46 to form dirt or rain marks on the outer vertical surface.

The following describes an installation process of the facade structure according to the present invention with reference to the accompanying drawings. The sealing strip 7 shown in fig. 4 is sleeved on the corresponding position of the bottom wall of the outer upright post 2 by an operator. The outer uprights 2 are then erected for pre-positioning. For the first section of the outer column 2 closest to the ground, a spacer or the like may be set up on the base of the elevator hoistway 6 to adjust the height so that the bolt is aligned with the bolt hole on the outer column 2 of the elevator hoistway 6. The outer uprights 2 are then vertically overlapped in a similar manner. After the outer column 2 is lapped, one end of the decorative plate 4 is obliquely inserted into the first sealing groove part 21 of the outer column 2, and then the other end of the decorative plate 4 is inserted into the second sealing groove part 22. In the same manner, the decorative panels 4 can be overlapped layer by layer in the order from the bottom up (see fig. 7). After the decorative plate 4 is erected to the highest floor, the shaft outer vertical surface top plate 1 is sealed at the top of the elevator shaft 6.

Alternatively, the angle steel upright 5 of the elevator shaft may not be provided with a through hole matched with the fastener 8 in advance. After the outer column 2 is erected, a worker can sequentially pass through the bottom wall of the outer column and the angle steel column 5 by using a drill. This can eliminate the alignment process of the outer columns.

In the case of maintenance inside the elevator shaft 6 or the facade structure, the personnel can quickly dismantle the structure in question in the reverse procedure described above.

After the decorative plates 4 of each floor are installed from bottom to top, optionally, the worker may fix the decorative plates 4 located at different vertical heights to the elevator shaft 6 selectively by means of bolting or the like. When only a certain area of the vertical height of the elevator shaft 6 or the facade structure needs to be maintained, a worker can only disassemble the decorative plates 4 of the height of the area without disassembling all the decorative plates 4 on the side.

Therefore, the utility model discloses an outer facade structure's installation need not be with the help of external crane etc to the installation is simple, therefore the staff can be convenient, install outer facade structure fast.

Meanwhile, compared with the existing facade structure, the facade structure does not need to be coated with engineering structural adhesive during installation. By means of the special matching relationship among the decorative plate 4, the waterproof cover plate 3 and the outer upright post 2, the outer facade structure can obtain good waterproof effect under the condition that engineering structural adhesive is not suitable.

The decorative plate 4 with a double-layer structure is arranged around the periphery of the elevator shaft 6, so that the elevator shaft 6 has heat preservation and fire resistance naturally; on the other hand, the double-layer structure of the decorative plate 4 enables the structural strength of the outer surface of the elevator to be remarkably improved.

According to the utility model discloses, see fig. 4, sealing strip 7 is protected layer upon layer by decorative board 4, sealing groove portion 21, 22, waterproof apron 3, consequently it is difficult for receiving the influence of foreign matter such as external rainwater. Even if the sealing strip 7 is ageing because of reasons such as the service life is too long, the staff can dismantle waterproof apron 3 and decorative board 4 fast, can change it after peeling off sealing strip 7.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the principles of the present invention.
