Description

Technical Field

[0001] This utility model relates to the field of node modification technology, and in particular to a structural node construction for adding a recessed escalator support. Background Technology

[0002] As an indispensable vertical transportation tool in modern buildings, the stability and safety of the escalator's support structure are directly related to the equipment's operating efficiency and passenger safety.

[0003] Traditional escalator supports are cast in one go during the construction of the main structure. If any are missing, the original structure must be recast or the original beams must be demolished and modified to add them. This process is complex and can easily disturb the original structure.

[0004] However, in actual engineering projects, especially in the renovation of existing building escalators or installation in special spaces, the following problems are often encountered:

[0005] Limited connection methods: Most supports use flat plate connections, which cannot adapt to complex building structures (such as irregular columns and inclined beams);

[0006] Space constraints: Existing building structures (such as beams and columns) may obstruct the direct installation of escalator supports, requiring local avoidance.

[0007] Difficulty in later maintenance: After the welded joints are corroded or the bolts are loose, it is difficult to repair locally and the whole thing needs to be replaced. Based on this, this utility model proposes a structural joint structure with a newly added escalator support recess. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model proposes a structural node construction for adding a recessed escalator support, which improves the performance of the escalator support recessed structure without affecting structural safety.

[0009] The technical solution to achieve the purpose of this utility model is as follows: a structural node structure for adding a recessed escalator support, including multiple original steel bars, multiple original stirrups welded to the outside of the multiple original steel bars, wherein new steel bars are welded to the original steel bars located in the middle, and multiple U-shaped stirrups are welded and fixed to the new steel bars, the two ends of the U-shaped stirrups are welded and fixed to the two sides of the original stirrups, and multiple L-shaped stirrups are welded to the new steel bars located in the middle, the ends of the L-shaped stirrups are welded and fixed to the top of the original stirrups.

[0010] In some embodiments, an original concrete beam and a structural main beam are cast together on the original reinforcing bars and original stirrups. The structural main beam is located at the bottom of the original concrete beam, and a groove is formed between the original concrete beam and the structural main beam.

[0011] In some embodiments, a concrete column is cast together between the original concrete beam and the main structural beam. Anchor plates are fixedly installed on both sides of the concrete column, and a through bolt is fixedly installed between a pair of anchor plates, with the through bolt penetrating through the concrete column.

[0012] In some embodiments, a connecting plate and an I-beam are welded and fixed to one side of the anchor plate, and the connecting plate and the I-beam are connected by a fixing bolt through a thread. The I-beam and the main structural beam are filled with a filling layer.

[0013] Compared with existing technologies, the significant advantages of this invention are:

[0014] Firstly, this utility model involves removing part of the surface layer at the beam where the escalator support is located to expose the reinforcing steel bars. Then, new reinforcing steel bars are welded to the original reinforcing steel bars to form a detailed node of the escalator recess. To meet the load requirements at the escalator support, a steel beam is added under the main beam where the escalator support is located for reinforcement, thereby strengthening the overall escalator support.

[0015] Secondly, this utility model enables dismantling and modification operations to be carried out within a relatively small area, and the modified concave structure can provide good support. At the same time, this structure greatly reduces the difficulty of construction and improves the convenience and efficiency of construction.

[0016] This solution addresses the problem that existing escalator supports are cast in one go when they are part of the main construction structure, but if any are missing, the original structure must be recast or the original beams must be extensively dismantled and modified to add them, which is complex and can easily disturb the original structure.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved structural node construction for a newly added escalator support recess. The technical solution of this utility model is as follows:

[0025] like Figures 1-3 As shown, a structural node for adding a recessed escalator support includes multiple original reinforcing bars 1, with multiple original stirrups 2 welded to the outside of the original reinforcing bars 1. New reinforcing bars 7 are welded to the original reinforcing bars 1 located in the middle, and multiple U-shaped stirrups 8 are welded and fixed to the new reinforcing bars 7. The two ends of the U-shaped stirrups 8 are welded and fixed to the two sides of the original stirrups 2. Multiple L-shaped stirrups 9 are welded to the new reinforcing bars 7 located in the middle, and the ends of the L-shaped stirrups 9 are welded and fixed to the top of the original stirrups 2. The new reinforcing bars 7, as well as the U-shaped stirrups 8 and L-shaped stirrups 9, can improve the ease of operation, realize the demolition and modification work within a small area, and greatly improve the construction efficiency.

[0026] Furthermore, the original concrete beam 3 and the structural main beam 5 are cast together on the original steel bar 1 and the original stirrup 2. The structural main beam 5 is set at the bottom of the original concrete beam 3. The original concrete beam 3 and the structural main beam 5 are connected by a groove 6. By cutting the small groove 6, the structural node of the escalator support recess can be modified, avoiding the interference with the original structure caused by the traditional large-scale demolition and modification method.

[0027] Furthermore, a concrete column 4 is cast together between the original concrete beam 3 and the main structural beam 5. Anchor plates 10 are fixedly installed on both sides of the concrete column 4. A through bolt 11 is fixedly installed between a pair of anchor plates 10. The through bolt 11 is fixedly inserted through the concrete column 4. The anchor plates 10 can improve the structural strength of the concrete column 4 near the escalator support recess, thereby improving the overall structural strength. It also facilitates the installation of the subsequent connecting plate 14 and I-beam 12.

[0028] Furthermore, a connecting plate 14 and an I-beam 12 are welded and fixed to one side of the anchor plate 10. The connecting plate 14 and the I-beam 12 are connected by a fixing bolt 15 through threads. The I-beam 12 and the main structural beam 5 are filled with a filling layer 13. The connecting plate 14 and the I-beam 12 can improve the support effect on the main structural beam 5 and meet the load requirements at the escalator support.

[0029] The specific working method is as follows: First, according to the range of the escalator support, the corresponding concrete is chiseled away, the top reinforcement is cut off, and the remaining reinforcement remains unchanged. The number of new reinforcement bars 7 is the same as the cut reinforcement bars. After bending, they are welded and fixed to the original reinforcement bars 1. The U-shaped stirrups 8 and L-shaped stirrups 9 are welded to the original stirrups 2 on one side. At the joint between the main beam 5 and the column, the through bolts 11 are passed through to the column. The connecting plate 14 is fixed to the column. The I-beam 12 is fixed to the connecting plate 14 by the fixing bolts 15. The other side is constructed in the same way. The I-beam 12 plays a role in reinforcing the newly added escalator support.
