Description

Technical Field

[0001] This invention relates to the field of steel structure connection node technology, specifically to a steel structure beam-column connection node construction. Background Technology

[0002] For example, Chinese patent CN113931306A discloses a steel structure beam-column connection node structure, including: a steel structure column, which includes multiple layers of columns, with adjacent layers of columns connected by a connecting device; a steel structure beam, which includes a box beam; a flange diaphragm, which is disposed at the end where the box beam connects to the steel structure column; the flange diaphragm includes multiple diaphragms, which are continuously arranged circumferentially along the end section of the box beam, with any diaphragm extending outward along the edge of the box beam; and a node connection mechanism.

[0003] The aforementioned patent improves the connection strength between steel beams and columns by layering steel columns according to beam spacing and setting node connection mechanisms between steel beams and columns, and synchronously filling concrete into the flange diaphragm and node connection mechanism after connection. However, the above solution has the following shortcomings: when the steel beam is damaged due to earthquake or other external reasons, it needs to be replaced. However, the original node in the aforementioned patent has been solidified with concrete. When replacing the steel beam, the entire node area can only be destructively demolished and rebuilt. The steel column itself is also damaged during the demolition process and cannot be reused, resulting in a huge waste of resources. Therefore, we propose a steel beam-column connection node structure. Summary of the Invention

[0004] The purpose of this invention is to provide a steel structure beam-column connection node structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A steel structure beam-column connection node structure includes a steel column and a steel beam. Two connection mechanisms are connected to the outside of the steel column to connect the steel column and the steel beam. The upper and lower ends of each connection mechanism are connected to an upper sealing plate and a lower sealing plate to seal the inside of the connection mechanism. A positioning hole is opened in the steel beam from top to bottom. A limiting mechanism is provided in the positioning hole. The upper end of the limiting mechanism passes through the upper sealing plate and the lower end passes through the lower sealing plate.

[0006] Preferably, the connecting mechanism includes a first U-shaped plate, a second U-shaped plate, and two first mounting bolts. Both ends of the first U-shaped plate and the second U-shaped plate are toothed. The first U-shaped plate and the second U-shaped plate are connected to each other by a plurality of connecting brackets. The second U-shaped plate is provided with a plurality of first mounting screws. The second U-shaped plate is mounted on the outside of the steel column by means of the first mounting screws. Two mounting through holes are opened in the steel beam.

[0007] Preferably, two blocks are fixedly connected between the first U-shaped plate and the second U-shaped plate, and insertion slots are provided in both the first U-shaped plate and the second U-shaped plate. Two connecting plates are fixedly connected to one side of the first U-shaped plate.

[0008] Preferably, both the upper and lower sealing plates have through holes, the lower sealing plate is longer than the upper sealing plate, and both the upper and lower sealing plates have two second mounting screws.

[0009] Preferably, the limiting mechanism includes an upper sleeve, a lower sleeve, and a second mounting bolt. The upper sleeve and the lower sleeve are both inserted into the positioning hole. The upper end of the upper sleeve extends into the through hole in the upper sealing plate, and the lower end of the lower sleeve extends into the through hole in the lower sealing plate. The second mounting bolt passes through the upper sleeve and the lower sleeve.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention connects the steel column and the steel beam together through a connecting mechanism. After the lower sealing mechanism first seals the inside of the connecting mechanism, the grout is poured into the connecting mechanism. Then, the upper sealing mechanism is installed at the upper end of the connecting mechanism. After the grout solidifies, the connection between the steel column and the steel beam is completed. When the steel beam needs to be replaced, the upper and lower sealing mechanisms are removed in sequence, and the upper and lower ends of the connecting mechanism are exposed to the external environment, which makes it easy to remove the solidified grout from the connecting mechanism. At this time, the damaged steel beam can be replaced. Attached Figure Description

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 scope of protection of the present invention.

[0014] Please see Figures 1-6 The present invention provides a technical solution: Example 1: A steel structure beam-column connection node includes a steel column 6 and a steel beam 7. Two connection mechanisms are connected to the outside of the steel column 6 to connect the steel column 6 and the steel beam 7. The upper and lower ends of the connection mechanisms are connected to an upper sealing plate 5 and a lower sealing plate 2, which seal the inside of the connection mechanism. A positioning hole 10 is opened in the steel beam 7 from top to bottom. A limiting mechanism is provided in the positioning hole 10. The upper end of the limiting mechanism passes through the upper sealing plate 5 and the lower end passes through the lower sealing plate 2. The limiting mechanism includes an upper sleeve 9, a lower sleeve 8 and a second mounting bolt 4.

[0015] Both the upper sleeve 9 and the lower sleeve 8 are inserted into the positioning hole 10. The lower end of the upper sleeve 9 has a protrusion, and the upper end of the lower sleeve 8 has a recess. When the lower end of the upper sleeve 9 and the upper end of the lower sleeve 8 are both inserted into the positioning hole 10, the protrusion at the lower end of the upper sleeve 9 will be inserted into the recess at the upper end of the lower sleeve 8, so that the upper sleeve 9 and the lower sleeve 8 are installed together. The upper end of the upper sleeve 9 extends into the through hole 11 in the upper sealing plate 5, and the lower end of the lower sleeve 8 extends into the through hole 11 in the lower sealing plate 2.

[0016] The second mounting bolt 4 is inserted into the upper sleeve 9 and the lower sleeve 8. The lower end of the upper sleeve 9 is inserted into the positioning hole 10 in the steel beam 7 through the through hole 11 in the upper sealing plate 5. One end of the lower sleeve 8 is inserted into the positioning hole 10 in the steel beam 7 through the through hole 11 in the lower sealing plate 2. Then the lower end of the second mounting bolt 4 is passed through the upper sleeve 9 and the lower sleeve 8. Then the second mounting bolt 4 is tightened so that the upper sealing plate 5, the steel beam 7 and the lower sealing plate 2 are connected together.

[0017] Example 2: Based on Embodiment 1, in order to improve the firmness of the connection between the steel column 6 and the steel beam 7, the connection mechanism includes a first U-shaped plate 1, a second U-shaped plate 13, and two first mounting bolts 3. Both ends of the first U-shaped plate 1 and the second U-shaped plate 13 are toothed, which allows the two first U-shaped plates 1 and the second U-shaped plate 13 to be quickly connected together. The first U-shaped plate 1 and the second U-shaped plate 13 are connected to each other by several connecting brackets 17. The second U-shaped plate 13 is provided with several first mounting screws 14. The second U-shaped plate 13 is installed on the outside of the steel column 6 by the first mounting screws 14. Two mounting through holes 12 are opened in the steel beam 7 to snap the two second U-shaped plates 13 onto the outside of the steel column 6. Then, the second U-shaped plates 13 are fixed to the outside of the steel column 6 by the several first mounting screws 14.

[0018] Two blocks 18 are fixedly connected between the first U-shaped plate 1 and the second U-shaped plate 13. When the steel beam 7 is inserted into the insertion groove 16, the upper end of the steel beam 7 will contact the lower end of the block 18, and the slurry will be injected between the first U-shaped plate 1 and the second U-shaped plate 13. Under the obstruction of the block 18, the slurry will not enter the positioning hole 10 from above. Insertion grooves 16 are provided in both the first U-shaped plate 1 and the second U-shaped plate 13. Two connecting plates 15 are fixedly connected to one side of the first U-shaped plate 1.

[0019] Both the upper sealing plate 5 and the lower sealing plate 2 have through holes 11. The length of the lower sealing plate 2 is greater than that of the upper sealing plate 5. The lower end of the steel beam 7 is supported by the extended part of the lower sealing plate 2. Both the upper sealing plate 5 and the lower sealing plate 2 are provided with two second mounting screws 19. After both steel beams 7 are installed with the connecting plate 15, the grout is injected between the first U-shaped plate 1 and the second U-shaped plate 13. Under the obstruction of the stop block 18, the grout will not enter the positioning hole 10 from above. After the injection is completed, the lower end of the upper sealing plate 5 is brought into contact with the upper end of the first U-shaped plate 1 and the second U-shaped plate 13. The material of the grout can be gypsum-based low-alkali grout.

[0020] The limiting mechanism includes an upper sleeve 9, a lower sleeve 8, and a second mounting bolt 4. Both the upper sleeve 9 and the lower sleeve 8 are inserted into the positioning hole 10. The upper end of the upper sleeve 9 extends into the through hole 11 in the upper sealing plate 5, and the lower end of the lower sleeve 8 extends into the through hole 11 in the lower sealing plate 2. The second mounting bolt 4 passes through the upper sleeve 9 and the lower sleeve 8. One end of the lower sleeve 8 is inserted into the positioning hole 10 in the steel beam 7 through the through hole 11 in the lower sealing plate 2. Then, the lower end of the second mounting bolt 4 passes through the upper sleeve 9 and the lower sleeve 8. Finally, the second mounting bolt 4 is tightened, so that the upper sealing plate 5, the steel beam 7, and the lower sealing plate 2 are connected together.

[0021] Working principle: During use, two second U-shaped plates 13 are snapped onto the outside of the steel column 6. Then, the second U-shaped plates 13 are fixed to the outside of the steel column 6 by several first mounting screws 14. The upper end of the lower sealing plate 2 is connected to the lower end of the first U-shaped plate 1 and the second U-shaped plate 13, and then screwed into the steel column 6 by the second mounting screws 19, so that the lower sealing plate 2 is installed on the outside of the steel column 6. One end of the steel beam 7 is inserted into the insertion groove 16, and one end of the first mounting bolt 3 is passed through the connecting plate 15 and the mounting through hole 12 and tightened, so that the two connecting plates 15 and the steel beam 7 are installed together. After both steel beams 7 are installed with the connecting plate 15, the grout is injected between the first U-shaped plate 1 and the second U-shaped plate 13. Under the obstruction of the stop block 18, the grout will not enter the positioning hole 10 from above. After the injection is completed, the lower end of the upper sealing plate 5 is brought into contact with the upper end of the first U-shaped plate 1 and the second U-shaped plate 13, and screwed into the steel column 6 by the second mounting screw 19, so that the upper sealing plate 5 and the steel column 6 are installed together. The lower end of the upper sleeve 9 is inserted into the positioning hole 10 in the steel beam 7 through the through hole 11 in the upper sealing plate 5. Insert one end of the lower sleeve 8 into the positioning hole 10 in the steel beam 7 through the through hole 11 in the lower sealing plate 2. Then, pass the lower end of the second mounting bolt 4 through the upper sleeve 9 and the lower sleeve 8, and then tighten the second mounting bolt 4 to connect the upper sealing plate 5, the steel beam 7 and the lower sealing plate 2 together. At this time, the steel column 6 and the steel beam 7 are installed together. When it is necessary to remove the steel beam 7, remove the upper sealing plate 5 and the lower sealing plate 2, remove the first mounting bolt 3, remove the grout between the first U-shaped plate 1 and the second U-shaped plate 13, and then pull out the steel beam 7.
