Description

Technical Field

[0001] This utility model relates to the field of steel structure splicing technology, and in particular to a splicing structure for elevator steel structure columns and beams. Background Technology

[0002] Many older residential communities lack elevators, causing significant inconvenience for residents, especially the elderly. To improve residents' lives, some communities install elevators on the sides of older buildings. Currently, most of the steel frame structures for these elevators are constructed using traditional on-site welding of steel profiles, while some utilize prefabricated methods with bolted connections.

[0003] In existing elevator steel structure structures where the uprights and beams are joined by bolts and nuts, the uprights are integrally formed by bending, and for aesthetic reasons and to prevent cuts, their outer edges are rounded. Therefore, when the beam is assembled to one side of the upright, a relatively large gap will exist at the rounded corner between the beam and the upright (e.g., ...). Figure 5 , Figure 6 As shown at point A in the diagram, rainwater can enter the interior through this gap, making the bolts and nuts more susceptible to corrosion in a humid environment, thus accelerating their damage. Utility Model Content

[0004] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes a splicing structure for elevator steel structure columns and beams.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A splicing structure for elevator steel column and beam includes a column and beam spliced ​​by several bolts and nuts. The outer edges of the column are rounded. A sealing abutment block is provided at one end of the beam that abuts against the column. The inner side of the sealing abutment block is provided with an abutment bevel that fits against the rounded corner.

[0007] In some embodiments, the column includes a main frame plate with a cross-section of “U”, and both ends of the opening of the main frame plate are connected to connecting frame plates for connecting with crossbeams. The connecting frame plate includes a first connecting plate and a second connecting plate that are vertically connected. The other end edge of the first connecting plate is connected to the main frame plate, and the first connecting plate and the main frame plate are transitioned by rounded corners.

[0008] In some embodiments, the crossbeam includes a horizontal base plate, and bending frame plates are provided on both length edges of the horizontal base plate.

The other edge of the first bending plate is connected to the horizontal base plate, and a partition opening is formed between the two second bending plates. The sealing abutment block is provided on the width edge of the horizontal base plate.

[0009] In some embodiments, an end cap plate is provided at the end of the crossbeam, and a support plate is spaced vertically on one side of the end cap plate. The support plate is attached to the inner side of the second bending plate and includes two sets of first bolts and first nuts. The first bolts pass through the second connecting plate, the second bending plate, and the support plate in sequence and are then threadedly connected to the first nuts.

[0010] In some embodiments, a second bolt and a second nut are also included, wherein the second bolt passes through the end cap plate and the first connecting plate in sequence and is threadedly connected to the second nut.

[0022] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0023] like Figures 1-4 The above describes a splicing structure of elevator steel column and beam, which includes a column 1 and a beam 2 spliced ​​by several bolts and nuts. The outer edges of the column 1 are transitioned by rounded corners 3. The beam 2 is provided with a sealing edge abutting block 4 at one end abutting against the column 1. The inner side of the sealing edge abutting block 4 is provided with an abutting bevel 5 that fits against the rounded corner 3.

[0024] When assembling the column 1 and the beam 2, align the sealing block 4 at the end of the beam 2 with the rounded corner 3 area of ​​the column 1, so that the bevel 5 completely fits the outer surface of the rounded corner 3. Then, fasten the beam 2 and the column 1 with bolts and nuts. Then, cover the joint between the rounded corner 3 of the column 1 and the end of the beam 2 with the sealing block 4, effectively preventing rainwater penetration and reducing the risk of corrosion of the steel structure and bolts and nuts.

[0025] See Figure 1 , Figure 2 As shown, the column 1 includes a main frame plate 21 with a cross-section of "U". Both ends of the opening of the main frame plate 21 are connected to connecting frame plates 22 for connecting with the crossbeam 2. The connecting frame plate 22 includes a first connecting plate 23 and a second connecting plate 24 that are vertically connected. The other end edge of the first connecting plate 23 is connected to the main frame plate 21, and the first connecting plate 23 and the main frame plate 21 are transitioned by a rounded corner 3.

[0026] Its main frame plate 21 is integrally formed with the first connecting plate 23 and the second connecting plate 24 through a bending process; while the "𠃊" shaped main frame plate 21 and the connecting frame plates 22 on both sides form a support structure, which improves the bending stiffness of the column 1.

[0027] See Figure 1 , Figure 3 , Figure 4As shown, the crossbeam 2 includes a horizontal base plate 31, and bending frame plates 32 are provided on both length edges of the horizontal base plate 31. The bending frame plate 32 includes a first bending plate 33 and a second bending plate 34 that are vertically connected. The other edge of the first bending plate 33 is connected to the horizontal base plate 31, and a partition opening 35 is formed between the two second bending plates 34. The sealing edge abutment block 4 is provided on the width edge of the horizontal base plate 31.

[0028] The horizontal base plate 31 is bent on both sides to form a first bent plate 33 and a second bent plate 34, with a partition opening 35 between the two bent plates. The first bent plate 33 and the second bent plate 34 enhance the torsional resistance of the crossbeam, while the partition opening 35 can reduce the structural weight and provide installation space for bolts and nuts.

[0029] The edge sealing block 4 is integrally formed with the end of the horizontal base plate 31, and its inner edge bevel 5 matches the rounded corner 3 of the column 1.

[0030] See Figure 1 , Figure 3 , Figure 4 As shown, an end cap plate 41 is also provided at the end of the crossbeam 2. Support plates 42 are spaced vertically on one side of the end cap plate 41. The support plates 42 are attached to the inner side of the second bending plate 34. The end cap plate 41 also includes two sets of first bolts 43 and first nuts 44. The first bolts 43 pass through the second connecting plate 24, the second bending plate 34, and the support plate 42 in sequence and are threadedly connected to the first nuts 44.

[0031] By setting the end sealing plate 41, the opening at the end of the crossbeam 2 is further sealed to prevent rainwater from seeping in; then, the end sealing plate 41 is connected and fixed to the crossbeam 2 and the column 1 simultaneously by the first bolt 43 and the first nut 44.

[0032] See Figure 2 , Figure 3 As shown, it also includes a second bolt 51 and a second nut 52. The second bolt 51 passes through the end sealing plate 41 and the first connecting plate 23 in sequence and is threadedly connected to the second nut 52. Thus, the end sealing plate 41 can improve the sealing performance and connect with the column 1, thereby improving the assembly stability. In addition, the first bolt 43 and the second bolt 51 form a cross-shaped fastening, which improves the overall stability of the node and greatly enhances the stability of the beam 2 and the column 1 after assembly.

[0033] See Figure 3 , Figure 4As shown, a snap-fit ​​plate 61 is provided on the inner side of both support plates 42, and the two snap-fit ​​plates 61 are snapped into the partition opening 35. During installation, the snap-fit ​​plate 61 is inserted into the partition opening 35 of the crossbeam 2 to achieve self-locking fixation. In addition, by embedding the snap-fit ​​plate 61 into the partition opening 35, the support plate 42, the end sealing plate 41 and the crossbeam 2 can be quickly positioned.

[0034] Furthermore, a limiting plate 71 is provided on the side of the end sealing plate 41 away from the support plate 42. The limiting plate 71 is attached to and abuts against the inner side wall of the horizontal base plate 31. The limiting plate 71 is attached to the inner side wall of the horizontal base plate 31 to constrain the installation angle of the end sealing plate 41 and prevent the end sealing plate 41 from deforming due to external force and causing sealing failure.

[0035] See Figure 1 , Figure 2 As shown, after the column 1 and the beam 2 are assembled, the outer wall of the horizontal base plate 31 of the main frame plate 21 is flush with the outside wall, eliminating exposed protrusions in the structure. In addition, the flat appearance facilitates the subsequent installation of decorative panels and improves the overall aesthetics of the elevator shaft.
