Description

Technical Field

[0001] The present application relates to a nine-edge triangular face-to-T-section steel column structure and a manufacturing method thereof, and belongs to the technical field of supporting components in buildings. Background Art

[0002] The application and promotion of steel structure buildings in the construction industry is becoming more and more powerful, especially in large-span buildings such as stadiums, airports, platforms, bridges, etc. Steel structures have the characteristics of superior safety performance, beautiful appearance, and strong plasticity.

[0003] With the widespread application of steel structures, the requirements for the shape of buildings are getting higher and higher. Under the premise of considering the shape and satisfying the structural stress, the effective transmission of force at the nodes and the stability of the node structure are all key factors that need to be considered. Especially in some special-shaped structural buildings, during the construction of steel components and other components, walls, bridges, etc., there are poor connection nodes due to uneven force or unstable support, which in turn causes additional torque and bending moment in the use of the building, which is not conducive to the safety of the building. Summary of the invention

[0004] In view of this, the present application first provides a nine-edge triangular face turned T-section steel column structure, which not only achieves the stability of the internal structure of the supporting member, but also gives the supporting member a good load-bearing effect.

[0005] Specifically, the present application is implemented through the following scheme: A nine-sided triangular face-to-T-section steel column structure comprises a T-section steel column, a nine-sided triangular mechanism and a sealing plate. The top surface of the nine-sided triangular mechanism is a horizontal top surface, and its bottom is fixedly connected to the T-section steel column. The sealing plate is located in the nine-sided triangular mechanism.

[0006] The above structure can not only realize the conversion installation between T-section steel columns and triangular faces, but the special-shaped structure also increases the available space. When used in wall supports, bridge columns and other occasions, the force is widened from the four sides of the conventional cubic column to the nine sides. Combined with the triangular face of the section structure at the same level, the triangular stable structure has higher overall stability, allowing a small cross-section to have a large load-bearing effect.

[0007] Further, as a preference: The T-section steel column is a steel column formed by splicing three U-shaped boxes in a closed manner. More preferably, the angle θ between adjacent U-shaped boxes is 120°.

[0008] The nine-edge triangle structure includes three triangular face units, each of which has a different orientation but slices at the same level, so that the top of the nine-edge triangle structure is a horizontal top surface.

[0009] Preferred: The triangular surface unit is formed by splicing three bent plates, the upper part of the bent plate forms a triangle, and the lower part is fixedly connected to the T-section steel column. More preferably, the upper and lower junctions of the bent plates are connected by a sealing plate to achieve internal fixation of the nine-edge triangular mechanism.

[0010] A longitudinal stiffening rib is provided in at least one triangular face unit. More preferably, the longitudinal stiffening rib is connected to two sides of the triangular face unit and is parallel to the remaining side.

[0011] The T-section steel column is provided with an inner partition, and at least one inner partition is provided. More preferably, two inner partitions are provided, which are respectively located at the bottom of the T-section steel column and the middle section of the T-section steel column. The shape of the inner partition is consistent with the inner section of the T-section steel column, so that it is convenient for it to abut against the inner wall of the T-section steel column to achieve uniform force on the entire structure to the greatest extent. The two inner partitions are preferably arranged horizontally.

[0012] In the above structure, the T-section steel column at the bottom is convenient to construct and easy to install; the triangular surface at the top is a stable structure of a nine-sided triangle, and the overall structure is axially symmetrical. In load-bearing applications such as bridges and steel structures, it solves the design and production problems of force and T-section steel columns, bending and torsion joints, and nine-sided triangle mechanism connection points. It has the advantages of high structural stability, small cross-section and large load-bearing capacity, reasonable spatial distribution, and beautiful appearance.

[0013] The second purpose of the applicant is to provide a method for manufacturing the above-mentioned nine-edge triangular face-to-T-section steel column structure, the steps are as follows: Step 1: Assemble and weld to obtain three U-shaped boxes; Step 2: First, assemble and weld two of the U-shaped boxes, and ensure that the angle between the two U-shaped boxes is 120°, and then weld the third U-shaped box to the two assembled and welded U-shaped boxes to obtain a T-section steel column; Step 3: Weld six bent plates on the top of the T-section steel column to form three groups of V-shaped structures with openings facing inwards; Step 4: Assemble and weld three bent plates at the openings of the three V-shaped structures to form three triangular structures on the top of the T-section steel column; Step five: Assemble and weld sealing plates in the middle of the three triangular structures to obtain a finished nine-edged triangular mechanism converted to a T-section steel column structure.

[0020] The present application provides a nine-edge triangular face-to-T-section steel column structure, combined with Figure 1 , Figure 2 , Figure 3 , including a T-section steel column 1, a nine-edge triangular mechanism 2 and a sealing plate 3. The section (top surface) of the nine-edge triangular mechanism 2 is a horizontal top surface including nine edges 2d and three triangular structures 2e, and its bottom is fixedly connected to the T-section steel column 1. The sealing plate 3 is located in the nine-edge triangular mechanism 2 and transmits force longitudinally when subjected to force, thereby achieving internal stability of the nine-edge triangular mechanism 2.

[0021] in: The T-section steel column 1 is composed of three U-shaped boxes 11, which form a closed special-shaped T-shaped structure. Each U-shaped box includes a first side wall 12 and a second side wall 13. Figure 4 , the angle θ between adjacent U-shaped boxes 11 is 120 ˚. During the installation of adjacent U-shaped boxes 11, the brazing material 15 can be firstly filled into the outer larger and inner smaller gap formed at the adjacent plates of the adjacent U-shaped boxes 11, and then the steel block 16 is fixed inside the gap, and then the part is welded to ensure that the connection nodes of the adjacent U-shaped boxes 11 are evenly stressed.

[0022] The nine-edge triangle mechanism 2 includes three: a triangle unit 1 2a, a triangle unit 2b, and a triangle unit 2c. Figure 2 The triangular face unit 2a, the triangular face unit 2b, and the triangular face unit 2c have different orientations but the slices are at the same level, so that the top of the nine-edge triangular mechanism 2 is a horizontal top surface.

[0023] Specifically, combined with Figure 5The three triangular face units are all formed by splicing three bending plates, namely bending plate 1 21, bending plate 22, and bending plate 3 23. Bending plate 1 21 and bending plate 22 are divided into an upper part 24 and a lower part 25. The upper part 24 and the lower part 25 are an integral bending structure. The inner side of the junction of the upper part 24 and the lower part 25 is connected with a sealing plate 3 to achieve the internal fixation of the nine-edge triangular mechanism 2. The upper part 211 of the three bending plates is spliced ​​to form a triangular structure 2e. The outer side of the lower part of bending plate 1 21 is connected to the second side wall 13. The lower part of bending plate 3 23 is located on the inner side of the first side wall 12. The lower part of bending plate 22 is located in the T-section steel column 1 and its two side edges are connected to the inner wall of the T-section steel column 1.

[0024] Preferred: Combination Figure 5 Taking one of the triangular surface units as an example, the top of the U-shaped box 11 protrudes upward, so that a groove 14 is formed between it and the first side wall 12 and the second side wall 13 on both sides, which facilitates the fixation of the bending plate 1 21, the bending plate 3 23 and the U-shaped box 11.

[0025] As an alternative: Combine Figure 5 At the top surface of the above-mentioned triangular structure, a triangular face end sealing plate 26 of corresponding specifications can be installed. The triangular face end sealing plate 26 is embedded in the triangular structure 2e to seal the top of the triangular face unit. Three triangular face end sealing plates 26 can be provided, that is, each triangular unit corresponds to a triangular face end sealing plate 26.

[0026] As an alternative solution: longitudinal stiffening ribs 4 are provided in each triangular surface unit, combined with Figure 6 The longitudinal stiffening rib 4 is connected to two sides of the triangular surface unit and is parallel to the remaining side. The longitudinal stiffening rib 4 supports the triangular structure in the triangular surface unit and assists the three bent plates in stabilizing the structure. Figure 6 For example: the longitudinal stiffening rib 4 is connected to the bending plate 1 21 and the bending plate 3 23 , and is parallel to the bending plate 22 .

[0027] As an alternative: Combine Figure 6 , an inner partition 5 is provided in the T-section steel column 1, and at least one inner partition 5 is provided. For example, two inner partitions can be provided in each nine-edge triangle mechanism rotating T-section steel column structure, one inner partition is located at the bottom of the T-section steel column 1, and the other inner partition is located in the middle section of the T-section steel column 1. The shape of the inner partition 5 is consistent with the inner section of the T-section steel column 1, so that it is convenient for it to rest against the inner wall of the T-section steel column 1 to achieve uniform force on the entire structure to the greatest extent. The two inner partitions 5 are preferably arranged in the horizontal direction.

[0028] The manufacturing method of the above-mentioned nine-edge triangle mechanism turning T-section steel column structure comprises the following steps: Step 1, constructing the U-shaped box 11: assembling and welding three U-shaped boxes 11 separately. During the assembly process, a cross support is added inside the U-shaped box 11 to prevent the U-shaped box 11 from deformation.

[0029] Step 2, fix the inner partition 5: assemble and weld two of the assembled U-shaped boxes at an inclination angle of 30° relative to the horizontal plane (that is, the angle θ is 120°), and weld both sides of the inner partition 5 to the inner grooves opened on the inner sides of the two U-shaped boxes 11.

[0030] Step three, construct a T-section steel column 1: cover the two assembled and welded U-shaped boxes with a third U-shaped box from above, and weld the weld between the third U-shaped box and the two assembled U-shaped boxes; at the same time, weld the weld between the two inner partitions 5 and the third U-shaped box through the channels at the upper and lower ends of the U-shaped box 11 to obtain a T-section steel column 1.

[0031] Step 4, constructing the triangular structure 2e: first, assemble and weld the six bending plates 1 21 and 3 23 on the outer edge side of the U-shaped box 11 to the top of the T-section steel column 1; then assemble the three longitudinal stiffening ribs 4 at the angle between the bending plates 1 21 and 3 23, and weld the welds with the six bending plates 1 21 and 3 23 at the angle; finally, assemble the three bending plates 22 on the inner sides of the six bending plates 1 21 and 3 23 to form a triangular structure 2e, and weld the outer welds of the triangular structure 2e; weld the welds between the bending plates 22 through the middle of the triangular structure 2e to complete the construction of the three triangular structures 2e.

[0032] Step 5: Install the sealing plate 3: Assemble the sealing plate 3 between the three triangular structures 2e, and weld the gap between the sealing plate 3 and the adjacent second bending plate 22; Step six, installing the triangular surface end sealing plate 26: assemble a triangular surface end sealing plate 26 in each triangular structure 2e, and weld the gap between the triangular surface end sealing plate 26 and the inner wall of the triangular structure 2e.

[0033] The above steps complete the construction of the lower T-section steel column 1 and the upper nine-edge triangle mechanism 2.

[0034] In the above structure, the T-section steel column 1 at the bottom is composed of three U-shaped boxes 11, which is convenient for construction and easy to install; the nine-sided triangle mechanism 2 at the upper part is a nine-sided triangle stable structure. When installed, the top of the structure forms nine edges 2d with the corresponding wall or bridge, and the nine-sided contacts are all on the same horizontal plane, which disperses the force well and realizes a large load-bearing capacity with a small cross-section; the overall structure is an axisymmetric special-shaped structure, which is convenient for supporting narrow and special-shaped spaces, has high structural stability, reasonable spatial distribution, and beautiful appearance.

[0035] The above-mentioned embodiments only express several feasible implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention, and the embodiments are not used to limit the scope of protection in the claims of the present invention. For ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and all equivalent implementations or changes that do not depart from the present invention should be included in the technology of the present invention.
