Description

Technical Field

[0001] This utility model belongs to the technical field of steel structure building materials, and in particular relates to a steel component beam-column connection assembly. Background Technology

[0002] Steel structure buildings are widely used in industrial plant construction, large public buildings, and super high-rise buildings due to their advantages such as fast construction speed, high strength, light weight, and good seismic performance. As the main load-bearing components of a building, beams and columns in steel structures are usually connected by welding and bolts. That is, after the construction hoisting and positioning are completed and the precision adjustment is completed, the temporary fixation is followed by bolt tightening and welding. Steel structure beam and column components are usually I-shaped, U-shaped, and tubular structures. Among them, tubular structures have good bending and torsional stiffness in all directions and can efficiently bear loads from different directions, especially suitable for bearing axial pressure and bending moment.

[0003] However, the following technical problems still exist in the installation and construction process: the connection of existing pipe columns and pipe beams relies on manual visual inspection or auxiliary tools for positioning. When the pipe columns and pipe beams are hoisted and connected, problems such as pipe joint misalignment and displacement are prone to occur. This misalignment makes it difficult to control the error, increases the difficulty of subsequent construction, and at the same time, repeated manual adjustments are time-consuming and laborious, affecting construction efficiency.

[0004] To address the aforementioned issues, this application proposes a steel beam-column connection assembly. Utility Model Content

[0005] The technical problem this utility model aims to solve is that the connection between pipe columns and pipe beams relies on manual visual inspection or auxiliary tools for positioning. When hoisting and connecting pipe columns and pipe beams, pipe joint misalignment and displacement are prone to occur, and the manual adjustment and alignment process is time-consuming and labor-intensive, affecting construction efficiency.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a steel structural beam-column connection assembly, comprising: a pipe column, a pipe beam, a connecting plate, a beam support, and an L-shaped fixing plate. The pipe column and pipe beam are tubular structures. The beam support is fixedly connected to the outer wall of the pipe column and consists of a support plate and diagonal bracing. It also includes a conical boss. The bottom of the conical boss has a connecting section adapted to the internal cross-section of the pipe column, and the upper part is a trapezoidal protrusion with a smaller top cross-section than the bottom cross-section. The top edge of the conical boss is rounded. The bottom connecting section of the conical boss is inserted into the pipe cavity of the pipe column, and the upper trapezoidal protrusion of the conical boss protrudes from the pipe opening. A positioning boss is fixed on the upper surface of the support plate. A positioning hole adapted to the positioning boss is opened on the lower surface of the end of the pipe beam. The support plate has two rows of bolt holes arranged from one end connected to the pipe column to the other end. The two rows of bolt holes are used for connecting with the pipe beam.

[0008] Furthermore, the diagonal brace is supported at the bottom of the support plate; the diagonal brace is a right triangle, and its right-angled sides are welded and fixed to the side wall of the column and the bottom of the support plate, respectively.

[0009] Furthermore, the upper surface of the support plate is parallel to the nozzle surface of the tube column, and the side of the support plate that contacts the tube column is welded and fixed to the tube column.

[0010] Furthermore, the tube column has two rows of bolt holes on the side wall located on the upper part of the support plate, and the bolt holes on the side wall of the tube column are threaded.

[0011] Furthermore, the positioning boss is located between two rows of bolt holes, the positioning boss is hemispherical in shape, and the positioning hole is a trapezoidal hole with an outer opening larger than the inner opening.

[0012] Furthermore, the diameter of the positioning boss is smaller than the inner opening of the positioning hole, and the distance between the center of the positioning hole and the end face of the pipe beam is greater than the distance between the center of the positioning boss and the corresponding side of the pipe column.

[0013] Furthermore, four connecting plates are evenly and symmetrically arranged at the top and bottom of the tubular column, with the length direction of the connecting plates parallel to the length direction of the tubular column, and a useful notch is opened at the end of the connecting plate near the tubular column.

[0014] Furthermore, it also includes clamping plates for clamping the vertically aligned connecting plates and securing them with a group of bolts.

[0015] Furthermore, the L-shaped fixed plate includes a long plate and a short plate that are perpendicular to each other. The longitudinal section of the L-shaped fixed plate is L-shaped. Bolt holes are arranged on both the long plate and the short plate of the L-shaped fixed plate. Bolt holes are arranged on the side and bottom of the pipe beam. The number, spacing and position of the bolt holes at the bottom of the pipe beam correspond to the bolt holes of the beam support. The number, spacing and position of the bolt holes on the side of the pipe beam correspond to the bolt holes on the long side of the L-shaped fixed plate. Threads are provided in the bolt holes of the pipe beam.

[0016] Furthermore, at least one stop is pre-welded into the cavity of the tubing, and the distance between the upper surface of the stop and the end face of the tubing opening is equal to the length of the bottom connecting section of the conical boss.

[0017] This utility model has the following beneficial effects:

[0018] The inclined guide function of the conical boss enables the pipe opening of the upper pipe column to be automatically guided, corrected and aligned with the pipe opening of the lower pipe column during the hoisting and lowering process; the process does not require workers to repeatedly visually inspect and pry to adjust, simplifying the complex alignment operation into simple hoisting and positioning, solving the problems of misalignment and offset, and improving construction efficiency.

[0019] The pipe beam installation utilizes the truncate hole of the positioning hole and the hemispherical fit of the positioning boss. During horizontal hoisting, the pipe beam can naturally slide into the predetermined position, which not only provides installation guidance but also plays a role in axial and radial limiting. This ensures that a uniform and consistent assembly gap is formed between the end of the pipe beam and the side of the pipe column, thereby improving the welding quality.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] Please see Figures 1 to 2 As shown, this utility model is a steel beam-column connection assembly, including a pipe column 1, a pipe beam 2, a conical boss 3, and an L-shaped fixing plate 7; the pipe column 1 and the pipe beam 2 are tubular structures; the bottom of the conical boss 3 has a connecting section adapted to the internal cross-section of the pipe column 1, the upper part is a platform-shaped protrusion, the top cross-section is smaller than the bottom cross-section, and the top edge of the conical boss 3 is rounded; the bottom connecting section of the conical boss 3 is inserted into the cavity of the pipe column 1, and a pre-welded and fixed stop block is provided in the cavity of the pipe 1, the distance between the upper surface of the stop block and the pipe opening is equal to the length of the connecting section; at least one stop block is pre-welded into the cavity of the pipe column 1, and the upper surface of the stop block is close to the pipe opening end face of the pipe column 1. The distance between them is equal to the length of the bottom connecting section of the conical boss 3; the connecting section is inserted into the cavity and abuts against the upper surface of the stop block; the upper platform-shaped protrusion of the conical boss 3 protrudes from the pipe opening; during installation, first, the lower pipe column 1 is vertically fixed so that the conical boss 3 faces upward, and then the upper section of the pipe column 1 is hoisted and connected, and the pipe opening at the bottom of the pipe column 1 is aligned with the conical boss 3, so that the top of the platform-shaped protrusion of the conical boss 3 slides into the pipe opening at the bottom of the pipe column 1. After the conical boss 3 contacts the inner wall of the pipe opening at the bottom of the pipe column 1, it generates a guiding effect, and the conical boss 3 forces the bottom pipe opening of the upper pipe column 1 to be precisely aligned and coincide with the pipe opening of the lower pipe column 1.

[0036] Please see Figure 3 As shown, four connecting plates 4 are evenly and symmetrically arranged at the top and bottom of each section of the pipe column 1. The sides of the connecting plates 4 are welded to the outer side wall of the pipe column 1, and the length direction of the connecting plates 4 is parallel to the length direction of the pipe column 1. A useful notch is opened at the end of the connecting plate 4 near the pipe column 1, which provides space for welding operations.

[0037] Please see Figures 4 to 5As shown, when the pipe openings of the upper and lower pipe columns 1 are aligned, the connecting plate 4 at the bottom of the upper pipe column 1 and the connecting plate 4 at the top of the lower pipe column 1 are also aligned; clamping plates 41 are used to clamp the aligned connecting plates 4 from both sides and the bolts are used to tighten them.

[0038] Please see Figure 6 As shown, a beam support 5 is fixedly connected to the outer wall of the column 1. The beam support 5 consists of a support plate 51 and a diagonal brace 52. The diagonal brace 52 is supported at the bottom of the support plate 51. The diagonal brace 52 is a right triangle, and its right-angled sides are welded and fixed to the side wall of the column 1 and the bottom of the support plate 51, respectively. The upper surface of the support plate 51 is parallel to the pipe opening surface of the column 1. The side of the support plate 51 that contacts the column 1 is welded and fixed to the column 1. The support plate 51 has two rows of bolt holes connected to the pipe beam 2 arranged from one end connected to the column 1 to the other end. Two rows of bolt holes are opened on the side wall of the column 1 located at the upper part of the support plate 51. The bolt holes opened on the side wall of the column 1 are threaded.

[0039] Please see Figures 6 to 9 As shown, a positioning boss 8 is fixed on the upper surface of the support plate 51. The positioning boss 8 is located between two rows of bolt holes. The positioning boss 8 is hemispherical in shape. A positioning hole 6 that matches the positioning boss 8 is opened on the lower surface of the end of the pipe beam 2. The positioning hole 6 is a frustum-shaped hole with an outer opening larger than the inner opening. The diameter of the positioning boss 8 is smaller than the inner opening of the positioning hole 6. The distance between the center of the positioning hole 6 and the end face of the pipe beam 2 is greater than the distance between the center of the positioning boss 8 and the corresponding side of the pipe column 1. The difference is the design width of a single standard weld. During installation, by fitting the positioning hole 6 of the pipe beam 2 into the positioning boss 8, the pipe beam 2 can be guided to be accurately positioned, so that a gap with uniform width suitable for welding is formed between its end and the pipe column 1.

[0040] The L-shaped fixing plate 7 includes a long plate and a short plate that are perpendicular to each other. The longitudinal section of the L-shaped fixing plate 7 is L-shaped. Bolt holes are provided on both the long plate and the short plate of the L-shaped fixing plate 7.

[0041] Bolt holes are provided on the side and bottom of the tube beam 2. The number, spacing and position of the bolt holes on the bottom of the tube beam 2 correspond to the bolt holes of the beam support 5. The number, spacing and position of the bolt holes on the side of the tube beam 2 correspond to the bolt holes on the long side of the L-shaped fixing plate 7. The bolt holes of the tube beam 2 are threaded. After the tube beam 2 is installed and aligned, bolts are used to connect the long side of the L-shaped fixing plate 7 to the end of the tube beam 2. The short side of the L-shaped fixing plate 7 is connected to the side wall of the tube column 1.

[0042] A specific application of the operation flow of this embodiment is as follows:

[0043] During installation, first fix the lower pipe column 1 vertically so that the conical protrusion 3 faces upward; when hoisting the upper pipe column 1, align its bottom pipe opening with the conical protrusion 3 so that the top of the conical protrusion 3 slides into the pipe opening; under the guiding action of the inclined surface of the conical protrusion 3, the pipe opening of the upper section of the pipe column 1 is automatically corrected and aligned, and finally coincides with the pipe opening of the lower pipe column 1; when the pipe openings of the upper and lower sections of the pipe column 1 are aligned, the corresponding connecting plates 4 are also aligned, and clamps 41 are used to clamp the upper and lower aligned connecting plates 4 from both sides, and then tighten them with bolts.

[0044] When installing the pipe beam 2, the pipe beam 2 is horizontally hoisted and the positioning boss 8 and the positioning hole 6 are matched to fit the positioning hole 6 of the pipe beam 2 into the positioning boss 8, guiding the pipe beam 2 to be accurately positioned. Bolts are passed through the bolt holes on the support plate 51 and tightened with the threaded holes at the bottom of the pipe beam 2 to fix the pipe beam 2 on the beam support 5.

[0045] The long side of the L-shaped fixing plate 7 is attached to the side of the pipe beam 2, and the short side is attached to the side wall of the pipe column 1. Bolts are used to connect the pipe beam 2 to the threaded hole on the side of the pipe beam 2 through the bolt hole on the long side of the L-shaped fixing plate 7, and to connect the pipe beam 2 to the threaded hole on the side wall of the pipe column 1 through the bolt hole on the short side, thereby fixing the end of the pipe beam 2 to the pipe column 1.

[0046] On-site welding is performed between the end of the tube beam 2 and the tube column 1, and at the gap between the upper and lower tube columns 1, to form a stronger rigid joint.
