Description

Technical Field

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

[0002] Beam-column joints are an important part of maintaining the load-bearing capacity of steel structures, and consist of steel columns and steel beams.

[0003] Traditional steel structure connections mainly consist of two types: bolts and welding. Beam-column joints generally include all-bolted connections, all-welded connections, and connections combining bolts and welding.

[0004] However, bolted connections place high demands on steel component processing and on-site construction. For example, the holes on the steel columns and beams must be aligned before the bolts are inserted, and a large number of bolts need to be connected, resulting in a long operation time. Welded connections are greatly affected by the construction environment and the skill level of the workers, involving a large amount of welding work. Welders need to work at heights for extended periods, and large-scale welding cannot be carried out in extreme weather. In other words, traditional steel structure connection methods involve a large amount of on-site construction, require a significant investment of manpower, and have low assembly efficiency. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem of low assembly efficiency of traditional steel structure connection methods, thereby providing a steel structure beam-column connection structure and prefabricated building.

[0006] To solve the above-mentioned technical problems, the present invention provides a steel structure beam-column connection structure, comprising:

[0007] A steel column, wherein the side of the steel column is provided with an outwardly extending support plate;

[0008] A steel beam is supported on a support plate of the steel column, and a snap-fit ​​structure that inserts vertically is provided between the bottom surface of the steel beam and the upper surface of the support plate.

[0009] Optionally, the steel beam has a vertical web, an upper flange plate horizontally connected to the upper end of the web, and a lower flange plate horizontally connected to the lower end of the web;

[0010] The support plate has two sets arranged at an interval, with the upper support plate supporting the bottom of the upper flange plate of the steel beam and the lower support plate supporting the bottom of the lower flange plate of the steel beam.

[0011] Optionally, the upper support plate has two spaced-apart plates, with the web of the steel beam being accommodated between the two upper support plates.

[0012] Optionally, at least one of the upper support plates is pre-installed on the steel column.

[0013] Optionally, the snap-fit ​​structure includes: a slot and a plug that cooperate with each other;

[0014] The slot is disposed on the support plate, and the insert is disposed on the bottom surface of the steel beam; and / or the slot is disposed on the bottom surface of the steel beam, and the insert is disposed on the support plate; during assembly, the insert is inserted into the slot in a vertical direction.

[0015] Optionally, the support plate has a plurality of spaced first protrusions, and the bottom surface of the steel beam has a second protrusion that mates with the first protrusions; during assembly, the first protrusions and the second protrusions are staggered and fitted together.

[0016] Optionally, it further includes: a first support member and a second support member that cooperate with each other, the first support member being disposed on the steel column, and the second support member being disposed on the web of the steel beam, wherein when the steel beam and the steel column are assembled, the first support member is supported on the bottom of the second support member.

[0017] Optionally, the first support member has two spaced apart, with the web of the steel beam being accommodated between the two first supports members.

[0018] Optionally, the web of the steel beam is provided with a clearance notch at the bottom of the second support member to avoid the first support member.

The steel beam is positioned by a snap-fit ​​structure between the bottom surface of the steel beam and the upper surface of the support plate, preventing relative movement between the steel beam and the steel column. Because both the support plate and the snap-fit ​​structure are fabricated in the factory, only on-site installation and partial welding are required, improving construction efficiency and thus solving the problem of low assembly efficiency in traditional steel structure connection methods.

[0022] 2. The steel beam-column connection structure provided by the present invention supports the bottom of the upper flange plate of the steel beam through the upper support plate and supports the bottom of the lower flange plate of the steel beam through the lower support plate, thereby supporting the web plate and the entire steel beam.

[0025] 5. The steel beam-column connection structure provided by the present invention, during assembly, achieves the snap-fit ​​connection between the support plate and the steel beam through the snap-fit ​​cooperation of the slot and the snap-fit ​​block, resists the lateral tensile force of the steel beam, thereby positioning the steel beam and preventing relative movement between the steel beam and the steel column.

[0026] 6. In the steel beam-column connection structure provided by the present invention, during assembly, the first protrusion on the support plate and the second protrusion on the bottom surface of the steel beam are staggered and interlocked to achieve a snap-fit ​​connection, resist the lateral tensile force of the steel beam, thereby positioning the steel beam and preventing relative movement between the steel beam and the steel column.

[0027] 7. The steel beam-column connection structure provided by the present invention, during assembly, the first support member on the steel column blocks and cooperates with the second support member on the web of the steel beam, which can resist the vertical torque generated by the weight of the steel beam itself and prevent the steel beam from falling downward.

[0040] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] This embodiment provides a steel beam-column connection structure that can be quickly installed for connecting steel beams and steel columns.

[0042] like Figure 1As shown, this embodiment provides a specific implementation of a steel beam-column connection structure, including: a steel column 1 and a steel beam 5; the side of the steel column 1 is provided with an outwardly extending support plate 2; the steel beam 5 is supported on the support plate 2 of the steel column 1, and a snap-fit ​​structure 9 inserted vertically is provided between the bottom surface of the steel beam 5 and the upper surface of the support plate 2.

[0043] In use, the support plate 2 extending outward from the side of the steel column 1 supports the steel beam 5. The steel beam 5 is positioned by the snap-fit ​​structure 9 between the bottom surface of the steel beam 5 and the upper surface of the support plate 2, preventing relative movement between the steel beam 5 and the steel column 1. The steel beam-column connection structure provided in this embodiment improves construction efficiency because both the support plate 2 and the snap-fit ​​structure 9 are manufactured in the factory, and only installation and partial welding are performed on site. This solves the problem of low assembly efficiency in traditional steel structure connection methods.

[0044] like Figure 1 As shown, in the steel beam-column connection structure provided in this embodiment, the steel beam 5 has a vertical web 6, an upper flange plate 7 horizontally connected to the upper end of the web 6, and a lower flange plate 8 horizontally connected to the lower end of the web 6. The support plate 2 has two sets arranged at intervals, wherein the upper support plate 3 supports the bottom of the upper flange plate 7 of the steel beam 5, and the lower support plate 4 supports the bottom of the lower flange plate 8 of the steel beam 5. The upper support plate 3 supports the bottom of the upper flange plate 7 of the steel beam 5, and the lower support plate 4 supports the bottom of the lower flange plate 8 of the steel beam 5, thereby supporting the web 6 of the steel beam 5 and the steel beam 5 as a whole. Alternatively, as an alternative embodiment, the steel beam 5 may also have a rectangular cross-section, with the upper support plate 3 supporting the inner side of the top plate of the steel beam 5 and the lower support plate 4 supporting the outer side of the bottom plate of the steel beam 5.

[0045] like Figure 2 As shown, in the steel beam-column connection structure provided in this embodiment, the upper support plate 3 has two spaced-apart pieces, and the space between the two upper support plates 3 is used to accommodate the web plate 6 of the steel beam 5. The web plate 6 of the steel beam 5 is sandwiched between the two upper support plates 3, which can prevent the steel beam 5 from shifting along the horizontal extension direction of the side wall of the steel column 1.

[0046] like Figure 1 , Figure 2As shown, in the steel beam-column connection structure provided in this embodiment, at least one of the upper support plates 3 is pre-installed on the steel column 1. During assembly, the upper flange plate 7 of the steel beam 5 is supported by the upper support plate 3 pre-installed on at least one side, enabling quick positioning and installation. Specifically, when two upper support plates 3 are pre-installed, the steel beam 5 is hoisted until it aligns with the gap between the two upper support plates 3, and then lowered until the upper flange plate 7 of the steel beam 5 lands on the upper support plate 3 and the lower flange plate 8 of the steel beam 5 lands on the lower support plate 4, completing the assembly; when one upper support plate 3 is pre-installed, the steel beam 5 is hoisted until the upper flange plate 7 lands on the pre-installed upper support plate 3 and the lower flange plate 8 lands on the lower support plate 4, and then it is translated until one side of the web plate 6 contacts the end face of the pre-installed upper support plate 3. After the steel beam 5 is in place, the other upper support plate 3 is installed. Alternatively, as an alternative implementation, the upper support plate 3 may not be pre-installed. After the steel beam 5 is hoisted to the point where the lower flange plate 8 and the lower support plate 4 are engaged, two upper support plates 3 are installed on both sides of the web plate 6 of the steel beam 5, so that the upper support plates 3 are engaged with the bottom surface of the upper flange plate 7.

[0047] like Figure 1-3 As shown, in the steel beam-column connection structure provided in this embodiment, the snap-fit ​​structure 9 includes: a matching slot and a plug; the slot is disposed on the support plate 2, and the plug is disposed on the bottom surface of the steel beam 5; and / or the slot is disposed on the bottom surface of the steel beam 5, and the plug is disposed on the support plate 2; during assembly, the plug is inserted into the slot in a vertical direction. Through the snap-fit ​​cooperation of the slot and the block, the support plate 2 and the steel beam 5 are snap-fit ​​connected, resisting the lateral tensile force of the steel beam 5, thereby positioning the steel beam 5 and preventing relative movement between the steel beam 5 and the steel column 1.

[0048] like Figure 2 , Figure 3As shown, in the steel beam-column connection structure provided in this embodiment, the support plate 2 has several spaced first protrusions 10, and the bottom surface of the steel beam 5 has second protrusions 11 that cooperate with the first protrusions 10. During assembly, the first protrusions 10 and the second protrusions 11 are staggered and interlocked. During assembly, the first protrusions 10 on the support plate 2 and the second protrusions 11 on the bottom surface of the steel beam 5 are staggered and interlocked, realizing the snap-fit ​​connection between the support plate 2 and the steel beam 5, resisting the lateral tensile force of the steel beam 5, thereby positioning the steel beam 5 and preventing relative movement between the steel beam 5 and the steel column 1. In addition, as an alternative embodiment, the first protrusions 10 and the second protrusions 11 can be omitted, and protrusions are provided on the bottom surface of the steel beam 5 and / or the support plate 2, and grooves are provided on the bottom surface of the support plate 2 and / or the steel beam 5, with the protrusions embedded in the grooves to achieve the snap-fit ​​connection.

[0049] like Figure 1-3 As shown, the steel beam-column connection structure provided in this embodiment further includes a first support member 12 and a second support member 13 that cooperate with each other. The first support member 12 is disposed on the steel column 1, and the second support member 13 is disposed on the web 6 of the steel beam 5. When the steel beam 5 is assembled with the steel column 1, the first support member 12 is supported at the bottom of the second support member 13. During assembly, the first support member 12 on the steel column 1 blocks the second support member 13 on the web 6 of the steel beam 5, which can resist the vertical torque generated by the weight of the steel beam 5 itself and prevent the steel beam 5 from falling downward. Alternatively, as an alternative embodiment, the first support member 12 and the second support member 13 can be omitted, and a support plate can be disposed below the support plate 2, through which the support plate 2 resists the vertical torque generated by the weight of the steel beam 5 itself.

[0050] like Figure 2 As shown, in the steel beam-column connection structure provided in this embodiment, there are two first support members 12 spaced apart, with the web 6 of the steel beam 5 accommodating between the two first support members 12. During assembly, the spaced-apart first support members 12 are located on both sides of the web 6 of the steel beam 5, which can prevent the steel beam 5 from shifting along the horizontal extension direction of the sidewall of the steel column 1. Specifically, two second support members 13 are symmetrically arranged on both sides of the web 6 of the steel beam 5. Alternatively, as an alternative embodiment, only one first support member 12 can be provided.

[0051] like Figure 1 , Figure 3As shown, in the steel beam-column connection structure provided in this embodiment, the web 6 of the steel beam 5 has a clearance notch 14 at the bottom of the second support member 13 to avoid the first support member 12. During assembly, the clearance notch 14 on the web 6 of the steel beam 5 can avoid the first support member 12, facilitating the adjustment of the position of the steel beam 5 along the horizontal extension direction of the side wall of the steel column 1, so that the steel beam 5 can be quickly installed in place. Specifically, the steel beam 5 is hoisted to the side of the steel column 1, keeping the clearance notch 14 on the web 6 of the steel beam 5 at the same elevation as the first support member 12, and the steel beam 5 is laterally moved until the web 6 is in the middle position of the two first support members 12, and then aligned and moved downward. Alternatively, as an alternative implementation, the clearance notch 14 can be omitted, and the horizontal position is adjusted during the hoisting of the steel beam 5 until the web 6 is aligned with the middle of the two first supports, and then the steel beam 5 is hoisted toward the steel column 1.

[0052] How to use

[0053] like Figure 1 As shown, in the steel beam-column connection structure provided in this embodiment, after the steel column 1 is installed in place, the steel beam 5 is installed. The steel beam 5 is hoisted to the side of the steel column 1, keeping the first support member 12 and the clearance notch 14 at the same elevation. The steel beam 5 is moved along the horizontal extension direction of the side of the steel column 1 until the web plate 6 of the steel beam 5 is located in the middle position of the two first support members 12, at which point the lateral movement stops. Then, the steel beam 5 is aligned and lowered until it lands on the support plate 2. Depending on the needs of the construction site, one side of the upper support plate 3 can be pre-installed before installation, and the other side of the upper support plate 3 can be used as a post-installation plate. After the steel beam 5 is in place, it is welded on site.

[0054] In addition, this embodiment also provides a prefabricated building that adopts the steel structure beam-column connection structure described in the above embodiments to achieve rapid installation of the steel structure beams and columns of the prefabricated building.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
