Description

Technical Field

[0001] This disclosure relates to a segmented beam assembly and an elevator system including the segmented beam assembly. Background Technology

[0002] In some elevator systems with multiple shafts, there is no separating wall between two adjacent and parallel shafts. To separate such shafts and / or to install guide rails for the elevator car between them, a load-bearing bracket is installed between the two shafts. This bracket includes a trimmer beam, with its ends fixed to opposite walls to provide support, much like a horizontal bar. The load-bearing bracket acts as a separating wall. Furthermore, the elevator car guide rails can be mounted to the trimmer beam.

[0003] Existing partition beams are heavy and mostly welded structures, making them difficult to install on-site and costly. There is a need for a partition beam that is easy to install and has lower weight and cost. Utility Model Content

[0004] At least some embodiments of this disclosure provide a segmented beam assembly comprising: two crossbeam members, a plurality of connecting members, and two fixing bracket modules. The two crossbeam members extend parallel to each other and spaced apart in a first direction. The plurality of connecting members are connected between the two crossbeam members, spaced apart from each other in the first direction. One of the two fixing bracket modules is fixed to one end of the two crossbeam members, and the other of the two fixing bracket modules is fixed to the other end of the two crossbeam members to secure the two crossbeam members to a fixture. The plurality of connecting members are detachably connected between the two crossbeam members, and at least one of the two fixing bracket modules is detachably connected to the two crossbeam members.

[0005] For example, in some embodiments of this disclosure, multiple connecting members are bolted between two crossbeam members, and at least one of the two fixing modules is bolted to the two crossbeam members.

[0006] For example, in some embodiments of this disclosure, the cross-section of the beam member in the first direction has a C-shaped profile, and the C-shaped profiles of the two beam members open away from each other in a second direction perpendicular to the first direction.

[0007] For example, in some embodiments of this disclosure, the C-shaped profile is axisymmetric. The beam member includes: a first beam segment located in the middle of the C-shaped profile; a second beam segment and a third beam segment extending perpendicularly from both ends of the first beam segment; and a fourth beam segment and a fifth beam segment extending perpendicularly toward the axis of symmetry of the C-shaped profile from the ends of the second beam segment and the third beam segment away from the first beam segment.

[0008] For example, in some embodiments of this disclosure, the crossbeam member further includes a plurality of mounting holes. The plurality of mounting holes are spaced apart from each other in a first direction in the second crossbeam section and the third crossbeam section.

[0009] For example, in some embodiments of this disclosure, the connecting member has a band-hat-shaped profile in its cross-section along a third direction, which is perpendicular to the first and second directions. The band-hat-shaped profile is axisymmetric. The connecting member includes: a first connecting segment located at the middle of the band-hat-shaped profile; a second connecting segment and a third connecting segment extending perpendicularly from both ends of the first connecting segment; and a fourth connecting segment and a fifth connecting segment extending perpendicularly away from the axis of symmetry of the band-hat-shaped profile from the ends of the second and third connecting segments away from the first connecting segment, respectively. The first connecting segment abuts against and is fixed to a first crossbeam segment of one of the two crossbeam members. The fourth and fifth connecting segments abut against and are fixed to the first crossbeam segment of the other of the two crossbeam members.

[0010] For example, in some embodiments of this disclosure, the bands of two adjacent connecting members of a plurality of connecting members open toward each other in opposite directions along the cap-shaped profile in a second direction.

[0011] For example, in some embodiments of this disclosure, a first connecting segment of the connecting member is secured to a beam member by threaded fasteners. A fourth and fifth connecting segments of the connecting member are secured to another beam member by threaded fasteners.

[0012] For example, in some embodiments of this disclosure, each fixing frame module includes two fixing members, which are respectively fixed to the two crossbeam members on both sides of the two crossbeam members in a third direction. The third direction is perpendicular to the first and second directions.

[0013] For example, in some embodiments of this disclosure, the segmented beam assembly further includes a first fixing screw and a second fixing screw. The fixing member includes a first plate-shaped body portion and a second plate-shaped fixing portion. The first plate-shaped body portion extends parallel to the second and third crossbeam segments. The second plate-shaped fixing portion extends perpendicularly from the first plate-shaped body portion. The fixing member is fixed to a fixture via the second plate-shaped fixing portion. The first fixing screw passes through mounting holes in the first plate-shaped body portions of the two fixing members in the fixing frame module and in the second and third crossbeam segments of one of the two crossbeam members to fix the two fixing members to both sides of a crossbeam member in a third-order direction. The second fixing screw passes through mounting holes in the first plate-shaped body portions of the two fixing members in the fixing frame module and in the second and third crossbeam segments of the other crossbeam member to fix the two fixing members to both sides of the other crossbeam member in a third-order direction.

[0014] For example, in some embodiments of this disclosure, the first plate-shaped main body is trapezoidal, and the second plate-shaped fixing part extends from the long parallel side of the trapezoid.

[0015] For example, in some embodiments of this disclosure, the segmented beam assembly further includes one or more mounting brackets for connecting to an external support, a third fixing screw, and a fourth fixing screw. The third fixing screw passes through mounting holes in the mounting bracket and mounting holes in the second or third crossbeam section of one of the two crossbeam members to secure the mounting bracket to one crossbeam member. The fourth fixing screw passes through additional mounting holes in the mounting bracket and mounting holes in the second or third crossbeam section of the other of the two crossbeam members to secure the mounting bracket to the other crossbeam member.

[0016] At least some embodiments of this disclosure also provide an elevator system comprising: a first shaft; a second shaft; and a dividing beam assembly as described above, disposed between the first shaft and the second shaft to separate the first shaft and the second shaft. A first direction is perpendicular to the extending direction of the first shaft and the second shaft, and the fixing element is a wall. Attached Figure Description

[0024] The segmented beam assembly according to embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0025] Figure 1 A perspective view of a segmented beam assembly according to an embodiment of the present disclosure is shown. Figure 2 A partially exploded perspective view of a segmented beam assembly according to an embodiment of the present disclosure is shown. Figure 3 A plan view of a segmented beam assembly according to an embodiment of the present disclosure is shown. Figures 1-3 As shown, the segmented beam assembly includes two crossbeam members 11, multiple connecting members 13, two mounting bracket modules, and a mounting bracket 14. The two crossbeam members 11 extend parallel to each other in a first direction X, and are also spaced apart in a second direction Y perpendicular to the first direction X. The multiple connecting members 13 are spaced apart from each other between the two crossbeam members 11 in the second direction Y, such that the multiple connecting members 13 and the two crossbeam members 11 constitute the main body of the segmented beam assembly. The two mounting bracket modules are respectively fixed to the two ends of the two crossbeam members 11 to secure them to a fixed object. Each mounting bracket module includes two fixing members 12. The mounting bracket 14 is used to connect an external support.

[0026] In this embodiment, the fixing object can be a wall. Some elevator systems include multiple shafts, and there is no separating wall between adjacent shafts. That is, the two shafts are connected to each other. In order to separate such two shafts and / or to install guide rails for guiding the elevator car between the two shafts, a load-bearing bracket is required between the two shafts, which may include a split beam assembly according to this disclosure. The fixing frame module of the split beam assembly is used to fix two crossbeams to the common wall facing each other of the two shafts. The split beam assembly is supported between the two opposing walls by the fixing frame module, for example, like a horizontal bar. Therefore, the split beam assembly can separate the two shafts. In addition, the split beam assembly can also be connected to the guide rail as an external support to support the guide rail.

[0027] Figure 4 Another plan view of a segmented beam assembly according to an embodiment of the present disclosure is shown, wherein the fixing frame module is omitted; Figure 5 It shows Figure 4 Enlarged plan view of box A in the middle; Figure 6 It shows from Figure 4 Another plan view of the segmented beam assembly according to an embodiment of this disclosure, viewed from the left and right directions, omits the fixing frame module. Figures 1-6 As shown, multiple connecting members 13 are detachably connected between two crossbeam members 11 in a manner such as bolts, and two fixing bracket modules are detachably connected to the two crossbeam members 11 in a manner such as bolts. Therefore, this segmented beam assembly facilitates on-site assembly, reducing installation time and cost. The crossbeam members 11 can be cut to the required length according to on-site needs, and then the fixing bracket modules at least one end can be installed to complete the assembly of the segmented beam assembly.

[0028] like Figures 1-6 As shown, the cross-section of the beam member 11 in the first direction X has a C-shaped profile, and the C-shaped profiles of the two beam members 11 open away from each other in the second direction Y. Figure 6As shown, the crossbeam member 11 includes a first crossbeam segment 111, a second crossbeam segment 112, a third crossbeam segment 113, a fourth crossbeam segment 114, and a fifth crossbeam segment 115, which together form a C-shaped profile. This C-shaped profile can be axisymmetric. Such a C-shaped profile allows the segmented beam assembly to have high rigidity while maintaining a low weight. The first crossbeam segment 111 is located in the middle of the C-shaped profile. The second crossbeam segment 112 and the third crossbeam segment 113 extend perpendicularly to the first crossbeam segment 111 from both ends of the first crossbeam segment 111, respectively. The fourth crossbeam segment 114 and the fifth crossbeam segment 115 extend perpendicularly to the axis of symmetry of the C-shaped profile from the ends of the second crossbeam segment 112 and the third crossbeam segment 113 away from the first crossbeam segment 111, respectively. Furthermore, rounded corners can be provided at the connections between adjacent crossbeam segments. Figures 1-5 As shown, a plurality of mounting holes 114 are provided in the second crossbeam section 112 and the third crossbeam section 113. The mounting holes 114 in the second crossbeam section 112 are spaced apart from each other in the first direction X, and the mounting holes 114 in the third crossbeam section 113 are also spaced apart from each other in the first direction X. As described in detail below, these mounting holes 114 can be used to mount the mounting bracket 14 for further mounting the guide rail. Since the mounting holes 114 are arranged along the first direction X, the mounting position of the mounting bracket 14 can be selected as needed. Furthermore, these mounting holes 114 can also be used to mount the bracket module.

[0029] In other embodiments, the crossbeam member 11 may have a profile of other shapes in the first direction X, such as a rectangular frame profile. Furthermore, mounting holes for mounting brackets, etc., may be provided at appropriate locations along the profile.

[0030] like Figures 2-4 As shown, a plurality of connecting members 13 are connected between two crossbeam members 11. These connecting members 13 are spaced apart from each other in a first direction X. The cross-section of each connecting member 13 in a third direction Z, perpendicular to the first direction X and the second direction Y, has a hat-shaped profile, the opening of which is oriented in the second direction Y. This hat-shaped profile can be axisymmetric. Figure 3 and Figure 4 As shown, in this embodiment, the openings of two adjacent connecting members 13 along the hat-shaped profile are oriented opposite to each other in the second direction Y, so as to make the force distribution of the segmented beam assembly more uniform, but this disclosure is not limited thereto.

[0031] like Figure 5As shown, the connecting member 13 includes a first connecting segment 131, a second connecting segment 132, a third connecting segment 133, a fourth connecting segment 134, and a fifth connecting segment 135. The first connecting segment 131, the second connecting segment 132, and the third connecting segment 133 form the main body of the brimmed cap, while the fourth connecting segment 134 and the fifth connecting segment 135 form the brim of the cap. Specifically, the first connecting segment 131 is located in the middle of the brimmed cap's outline. The second connecting segment 132 and the third connecting segment 133 extend perpendicularly to both ends of the first connecting segment 131. The fourth connecting segment 134 and the fifth connecting segment 135 extend perpendicularly to the axis of symmetry of the corresponding connecting segment away from the brimmed cap's outline from the ends of the second connecting segment 132 and the third connecting segment 133, respectively, away from the first connecting segment 131. Furthermore, rounded corners can be provided at the connection points between adjacent connecting segments. The first connecting segment 131 is abutted against and fixed to the first crossbeam segment 111 of one of the two crossbeam members 11, and the fourth connecting segment 134 and the fifth connecting segment 135 are abutted against and fixed to the first crossbeam segment 111 of the other of the two crossbeam members 11, respectively. Therefore, multiple connecting segments 13 can fix the two crossbeam members 11 together. The shape and connection configuration of the connecting segments 13 and the crossbeam members 11 result in a high rigidity of the segmented beam assembly while maintaining a low weight. The cost of the segmented beam assembly is also reduced due to the need for less material. Furthermore, such a segmented beam assembly can be easily installed on-site as needed. For example, firstly, the two crossbeam members 11 are cut to the required length; then, an appropriate number of connecting segments 13 are connected to the two crossbeam members 11; finally, the fixing frame module is assembled to the two crossbeam members 11 to complete the assembly of the segmented beam assembly. Since the crossbeam members 11 can be cut on-site as needed, it is not necessary to prepare multiple sizes and models of segmented beam assemblies, saving costs.

[0032] Furthermore, in this embodiment, the first connecting segment 131 of the connecting member 13 is fixed to a crossbeam member 11 using threaded fasteners, and the fourth connecting segment 134 and the fifth connecting segment 135 of the connecting member 13 are fixed to another crossbeam member 11 using threaded fasteners. Therefore, assembly can be easily completed without welding, reducing installation time and simplifying installation.

[0033] In other embodiments, the connecting member 13 may have other shapes of profile in the third direction Z, such as a rectangular frame profile.

[0034] See Figures 1-3The fixing module includes two fixing members 12, which are fixed to the two crossbeam members 11 on both sides of the two crossbeam members 11 in the third direction Z by a first fixing screw 151 and a second fixing screw 152. Figure 2 As shown, the fixing member 12 includes a first plate-shaped main body portion 121 and a second plate-shaped fixing portion 122. The first plate-shaped main body portion 121 extends parallel to the second crossbeam segment 112 and the third crossbeam segment 113. The second plate-shaped fixing portion 122 extends from the second plate-shaped main body portion 121 perpendicular to the first plate-shaped main body portion 121. The first plate-shaped main body portion 121 may be trapezoidal, and the second plate-shaped fixing portion 122 extends from the long parallel side of the trapezoid. The second plate-shaped fixing portion 122 may be rectangular. The fixing member 12 is fixed to a fixture such as a wall via the second plate-shaped fixing portion 122. Specifically, the second plate-shaped fixing portion 122 can be fixed to the fixture using expansion screws 17.

[0035] Figure 7 It shows from Figure 3 Another plan view of the segmented beam assembly according to an embodiment of this disclosure, viewed from the left and right directions. Figure 1-3 and Figure 7 As shown, the first fixing screw 151 passes through the mounting holes 114 in the second plate-shaped main body 121 of the two fixing members 12 in the fixing frame module and in the second beam section 112 and third beam section 113 of one of the two beam members 11, to fix the two fixing members 12 to both sides of one beam member 11 in the third direction Z. The second fixing screw 152 passes through the mounting holes 114 in the second plate-shaped main body 121 of the two fixing members 12 in the fixing frame module and in the second beam section 112 and third beam section 113 of the other beam member 11, to fix the two fixing members 12 to both sides of the other beam member 11 in the third direction Z. The long first fixing screw 151 and the long second fixing screw 152 enable the two fixing members 12 of the fixing frame module to be assembled to the split beam assembly more stably and conveniently.

[0036] In addition, see still Figures 1-3One or more mounting brackets 14 are secured to two crossbeam assemblies by third fixing screws 161 and fourth fixing screws 162 to assemble them into the segmented beam assembly. Specifically, the third fixing screw 161 passes through mounting holes in the mounting bracket 14 and mounting holes 114 in the second crossbeam section 112 or the third crossbeam section 113 of one of the two crossbeam members 11 to secure the mounting bracket 14 to one crossbeam member 11. The fourth fixing screw 162 passes through additional mounting holes in the mounting bracket 14 and mounting holes 114 in the second crossbeam section 112 or the third crossbeam section 113 of the other crossbeam member 11 to secure the mounting bracket 14 to the other crossbeam member 11. Therefore, the segmented beam assembly of the embodiments of this disclosure can achieve weld-free assembly.

[0037] In one example, the distance L1 between the fourth crossbeam segment 114 and the fifth crossbeam segment 115 of the two crossbeam members 11 in the second direction Y can be in the range of 100-200 mm, preferably in the range of 130-150 mm, for example, 140 mm. The distance between the first crossbeam segments 111 of the two crossbeam members 11 in the second direction Y can be in the range of 40-80 mm, preferably in the range of 50-70 mm, for example, 60 mm. The distance between the second crossbeam segment 112 and the third crossbeam segment 113 of each crossbeam member 11 in the third direction Z can be in the range of 80-150 mm, preferably in the range of 90-130 mm, for example, 120 mm. In one example, for a beam with a cross-sectional dimension of I200(L1)×100(L3)(mm) and a length of 2.5m, the weight of the segmented beam assembly according to the embodiments of this disclosure is only 30kg, which is 73% lighter, 63% cheaper, and 10% faster than conventional segmented beams of the same size and material.
