Description

Technical Field

[0001] This application relates to the field of elevator shaft technology, and more particularly to prefabricated elevator shafts. Background Technology

[0002] With the development of the times, residents of older, elevator-less residential buildings often experience inconvenience when going up and down stairs because elevators were not installed during construction. Existing elevators require pre-existing elevator shafts within the building structure before installation. However, since older, elevator-less buildings often lack pre-existing elevator shafts, it is necessary to install elevators nearby and connect them to the stairwells to improve residents' convenience. Therefore, before installing an elevator, an elevator shaft frame needs to be installed near the older, elevator-less residential building.

[0003] The existing elevator shaft frame requires the materials to be transported to the site for installation, and then cut, welded, and painted on-site to assemble the elevator shaft frame. The cutting and welding of the materials generates significant noise pollution, and the painting process releases harmful gases, thus affecting the normal lives of residents. Utility Model Content

[0030] refer to Figures 1 to 10 A preferred embodiment of the prefabricated elevator shaft according to this application will be described in detail below, wherein the prefabricated elevator shaft includes at least four vertical members 10, a horizontal component 20 and a plurality of connecting members 30.

[0031] Specifically, the four vertical members 10 are arranged vertically, and the vertical projections of the four vertical members 10 are respectively located at the four corners of the rectangle, so that the four vertical members 10 enclose a shaft 1001.

[0032] The horizontal assembly 20 includes at least one set of upper horizontal members 21, at least one set of lower horizontal members 22, and at least one set of middle horizontal members 23. Each set of upper horizontal members 21, each set of lower horizontal members 22, and each set of middle horizontal members 23 respectively includes four upper horizontal members 21, four lower horizontal members 22, and four middle horizontal members 23. The four upper horizontal members 21 are respectively disposed between adjacent vertical members 10, and the four upper horizontal members 21 are located at the upper end of the vertical member 10. The four lower horizontal members 22 are respectively disposed between adjacent vertical members 10, and the four lower horizontal members 22 are located at the lower end of the vertical member 10. The four central horizontal members 23 are respectively disposed between adjacent vertical members 10, and the four central horizontal members 23 are located in the middle of the vertical members 10, so as to stabilize the four vertical members 10 by the four upper horizontal members 21, the four lower horizontal members 22 and the four central horizontal members 23, so that the four vertical members 10 can stand vertically on the ground.

[0033] Several connecting members 30 are respectively disposed between the two ends of the upper horizontal member 21 and the vertical member 10, between the two ends of the lower horizontal member 22 and the vertical member 10, and between the two ends of the middle horizontal member 23 and the vertical member 10, so as to realize the connection between the upper horizontal member 21 and the vertical member 10, between the lower horizontal member 22 and the vertical member 10, and between the middle horizontal member 23 and the vertical member 10 through the connecting members 30.

[0034] Preferably, the vertical member 10, the upper horizontal member 21, the lower horizontal member 22, and the middle horizontal member 23 are all made of aluminum profiles. The connecting member 30 is made of aluminum profile corner bracket connectors.

[0035] It is worth mentioning that the lengths of the vertical component 10, the upper horizontal component 21, the lower horizontal component 22, and the middle horizontal component 23 are all predetermined lengths manufactured after leaving the factory. The installation of the prefabricated elevator shaft can be achieved simply by assembling it on the construction site, thus avoiding noise pollution and harmful gases during the on-site assembly of the prefabricated elevator shaft.

[0036] Preferably, the upper horizontal member 21, the lower horizontal member 22, and the middle horizontal member 23 are parallel to each other, and the upper horizontal member 21, the lower horizontal member 22, and the middle horizontal member 23 are all perpendicular to the vertical member 10.

[0037] In this embodiment, as Figures 1 to 6 and Figures 8 to 10As shown, the upper transverse member 21, the lower transverse member 22, and the middle transverse member 23 each form at least one upper transverse groove, at least one lower transverse groove, and at least one middle transverse groove along the extending direction. The middle transverse member 23 is implemented in multiple groups. The multiple groups of the middle transverse members 23 are evenly distributed along the extending direction of the vertical member 10, and the four middle transverse members 23 in each group are disposed between adjacent vertical members 10 via the connecting member 30 in a manner perpendicular to the vertical member 10.

[0038] The prefabricated elevator shaft also includes a sealing assembly 40. The sealing assembly 40 includes four upper sealing members 41, four lower sealing members 42, and multiple sets of middle sealing members 43. Each set of middle sealing members 43 includes four middle sealing members 43. Each upper sealing member 41 has an upper upper sliding part 411 adapted to the upper transverse groove. By having the upper upper sliding part 411 of each of the four upper sealing members 41 slide along the upper transverse groove formed by the four upper transverse members 21 in a locking manner with the upper transverse member 21, the four upper sealing members 41 are placed around the upper end of the shaft 1001 in an enclosing manner. The lower sealing member 42 has a lower sliding portion 421 adapted to the lower transverse groove. Each of the four lower sealing members 42 slides along the lower transverse groove formed by the four lower transverse members 22 in a manner that keeps them engaged with the lower transverse member 22, thereby placing the four lower sealing members 42 in an enclosing manner around the lower end of the shaft 1001. The four middle sealing members 43 of each group are evenly distributed between the upper sealing member 41 and the lower sealing member 42 along the extension direction of the vertical member 10, surrounding the middle of the shaft 1001. Each middle sealing member 43 has a middle common groove sliding portion 431 at both ends along the extension direction of the vertical member 10. The middle sealing member 43 is slidably disposed in the two middle transverse grooves by means of two middle common groove sliding portions 431, respectively, keeping them engaged with the two middle transverse members 23.

[0039] Specifically, the upper closure 41, the lower closure 42, and the middle closure 43 each have an upper common groove sliding portion 412 and a lower common groove sliding portion 422. The upper common groove sliding portion 412 is located at the end of the upper closure 41 away from the upper transverse member 21. The upper common groove sliding portion 412 is slidably disposed in the middle transverse groove in such a way that it is engaged with the middle transverse member 23 near the upper transverse member 21, and the upper common groove sliding portion 412 abuts against the middle common groove sliding portion 431 of one of the middle closure members 43 near the upper closure 41 and placed in the middle transverse groove. The lower common groove sliding portion 422 is located at the end of the lower closure 42 away from the lower transverse member 22. The lower common groove sliding portion 422 is slidably disposed in the middle transverse groove in such a way that it is engaged with the middle transverse member 23 near the lower transverse member 22, and the lower common groove sliding portion 422 abuts against the middle common groove sliding portion 431 of the other middle closure member 43 near the lower closure member 42 and placed in the middle transverse groove.

[0040] As an example, two adjacent middle layer common groove sliding portions 431 of adjacent middle layer closures 43 are placed into the middle transverse groove of the same middle transverse member 23 in a manner that keeps them engaged with the middle transverse member 23 and keeps them abutting each other, so as to improve the stability when two adjacent middle layer common groove sliding portions 431 of two middle layer closures 43 are placed into the same middle transverse groove by means of the abutting middle layer common groove sliding portions 431.

[0041] It is worth mentioning that the overall stability of the prefabricated elevator shaft is improved by the arrangement of the four upper-level enclosures 41, the four lower-level enclosures 42, and the multiple sets of middle-level enclosures 43. Simultaneously, by enclosing the shaft 1001 with the four upper-level enclosures 41, the four lower-level enclosures 42, and the multiple sets of middle-level enclosures 43, external contaminants are prevented from falling into the shaft 1001 from between the vertical member 10 and the horizontal assembly 20.

[0042] Preferably, one of the upper enclosures 41 and one of the lower enclosures 42 are provided with an upper opening 4101 and a lower opening 4201, respectively. One of the four middle enclosures 43 in each group is provided with a middle opening 4301. The upper opening 4101, the lower opening 4201, and the middle opening 4301 are all connected to the shaft 1001, and are all located on one side of the vertical direction of the shaft 1001, so that when the elevator is installed in the shaft 1001, users can easily enter and exit the elevator through the upper opening 4101, the lower opening 4201, and the middle opening 4301.

[0043] In another modified embodiment, such as Figures 7 to 9 As shown, the upper transverse member 21 and the lower transverse member 22 respectively form at least one upper transverse groove and at least one lower transverse groove along the extending direction. The prefabricated elevator shaft also includes a sealing assembly 40. The sealing assembly 40 includes four upper sealing members 41 and four lower sealing members 42. Each upper sealing member 41 has an upper upper sliding portion 411 adapted to the upper transverse groove. By means of the upper upper sliding portion 411 of each of the four upper sealing members 41, which are respectively engaged with the upper transverse member 21, the four upper sealing members 41 are slid along the upper transverse groove formed by the four upper transverse members 21, thereby placing the four upper sealing members 41 in an enclosing manner on the periphery of the upper end of the shaft 1001. The lower sealing member 42 has a lower sliding part 421 adapted to the lower transverse groove. The lower sliding parts 421 of each of the four lower sealing members 42 slide along the lower transverse groove formed by the four lower transverse members 22 in a manner that keeps them engaged with the lower transverse member 22. The four lower sealing members 42 are placed around the lower end of the shaft 1001 in an enclosing manner. The ends of the four upper sealing members 41 away from the upper transverse member 21 and the ends of the four lower sealing members 42 away from the lower transverse member 22 abut against each other. The four upper sealing members 41 and the four lower sealing members 42 enclose the vertical periphery of the shaft 1001, preventing external contaminants from falling into the shaft 1001 from between the vertical member 10 and the transverse component 20.

[0044] Specifically, the central transverse member 23 forms at least one central transverse groove. The upper closure member 41 also has an upper common groove sliding portion 412 that can be placed in the central transverse groove. The lower closure member 42 also has a lower common groove sliding portion 422 that can be placed in the central transverse groove. The upper common groove sliding portion 412 and the lower common groove sliding portion 422 abut against each other and are respectively located at the ends of the upper closure member 41 away from the upper transverse member 21 and the ends of the lower closure member 42 away from the lower transverse member 22. The upper common groove sliding portions 412 of the four upper closure members 41 and the lower common groove sliding portions 422 of the four lower closure members 42 are slidably disposed in the central transverse grooves formed by the four central transverse members 23 in a manner that keeps them engaged with the central transverse member 23.

[0045] It is worth mentioning that, since the upper common groove sliding part 412 of the upper sealing member 41 and the lower common groove sliding part 422 of the lower sealing member 42 are slidably disposed in the middle transverse groove in such a way that they abut against each other and are locked to the middle transverse member 23, the four upper sealing members 41 and the four lower sealing members 42 are more stable when they are respectively disposed on the periphery of the well 1001.

[0046] Preferably, one of the upper enclosures 41 and one of the lower enclosures 42 are respectively provided with an upper opening 4101 and a lower opening 4201. Both the upper opening 4101 and the lower opening 4201 communicate with the shaft 1001, and both are located on one side of the vertical direction of the shaft 1001, so that when the elevator is installed in the shaft 1001, the upper opening 4101 and the lower opening 4201 facilitate user access to and from the elevator.

[0048] Preferably, the lower edge of the lower opening 4201 of the lower closure member 42 remains abutted against the lower transverse member 22 to reduce the degree of deformation of the lower edge of the lower opening 4201 due to stepping during the use of the prefabricated elevator shaft. Similarly, the lower edges of the upper opening 4101 and the middle opening 4301 remain abutted against the middle transverse member 23 to reduce the degree of deformation of the lower edges of the upper opening 4101 and the middle opening 4301 due to stepping during the use of the prefabricated elevator shaft.

[0049] Preferably, the lower edge of the lower opening 4201 of the lower closure 42 is welded to the lower transverse member 22, and the lower edges of the upper opening 4101 and the middle opening 4301 are both welded to the middle transverse member 23.

Each upper edge stabilizing bar 51 is disposed between adjacent vertical members 10, and both ends of each upper edge stabilizing bar 51 are connected to the vertical member 10 via connecting members 30. Each frame member 50 is perpendicular to the vertical member 10. The multiple upper edge stabilizing bars 51 are respectively abutted against the upper edges of the upper opening 4101, the lower opening 4201, and the multiple middle openings 4301, so as to reduce the degree of deformation caused by collision of the upper edges of the upper opening 4101, the lower opening 4201, and the multiple middle openings 4301 during the use of the prefabricated elevator shaft.

[0051] Preferably, the upper edge of the upper opening 4101, the upper edge of the lower opening 4201, and the upper edges of the plurality of middle openings 4301 are all welded to the upper edge stabilizing rod 51.

[0053] More specifically, the other ends of the two side edge stabilizing rods 52 of one of the frame members 50 near the lower transverse member 22 are respectively connected to the lower transverse member 22 via the connecting member 30, and the other ends of the two side edge stabilizing rods 52 of the other frame members 50 near the middle transverse member 23 are respectively connected to the middle transverse member 23 via the connecting member 30, so that the side edge stabilizing rods 52 can be more stably maintained at the side edge of the upper opening 4101, the side edge of the lower opening 4201 and the side edge of the middle opening 4301.

[0054] Preferably, the two sides of the upper opening 4101, the two sides of the lower opening 4201, and the two sides of the middle opening 4301 are all welded to the side edge stabilizing rod 52.
