Description

Technical Field

[0001] This utility model belongs to the field of steel structure connection technology, and in particular relates to a weldless connection structure between steel components. Background Technology

[0002] Steel component connectors are a crucial part of steel structure engineering, much like the "joints" and "bones" of the human body. They firmly combine independent steel components such as beams, columns, and slabs into a unified structure through welding, bolting, or riveting. These connectors (such as gusset plates, bolts, welds, and connectors) not only transmit and coordinate the internal forces (such as tension, compression, shear, and bending moments) between components, but are also the core of ensuring the integrity, stability, and safety of the structure. Their design and construction quality directly determine the load-bearing capacity, stiffness, and seismic performance of the entire steel structure system.

[0003] Among them, bolted connections have the advantages of convenient construction, strong disassembly capability, and low dependence on operator skills. Bolted connections transmit force through friction generated by pre-tightening force, making installation and disassembly relatively convenient, and facilitating later maintenance, modification, or structural expansion. At the same time, the quality of bolted connections is easier to inspect and control through visual inspection and tools, resulting in high reliability. They are particularly suitable for steel structure projects that require large-scale production and rapid on-site installation.

[0004] To ensure the reliability of the horizontal and vertical connections, multiple bolt holes need to be installed at the connection between the column and the I-beam. Specifically, bolt holes that are very close together need to be made on multiple faces of the I-beam, and corresponding bolt holes also need to be installed on the column. The presence of bolt holes will affect the strength of the steel structure, and the close proximity will further affect the strength of the connection. Moreover, the multiple I-beams that are horizontally connected on the traditional column are installed independently, and their stability needs to be improved.

[0005] To address the aforementioned issues, this application proposes a weldless connection structure between steel components. Utility Model Content

[0006] The purpose of this utility model is to provide a weldless connection structure between steel components, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a connection structure between weldless steel components, including columns and several I-beams. The columns are arranged vertically, and the I-beams are vertically connected to the columns. A tie sleeve is fitted on the outside of the I-beams. The upper end of the tie sleeve is fixedly installed to the column through a tie plate. A support frame is provided between adjacent I-beams to support each other. The support frame also abuts between the tie sleeve and the column.

[0009] Furthermore, the support frame includes two triangular support plates distributed parallel to each other vertically. Right-angle connecting plates are fixed at the right angles of the two triangular support plates and are in close contact with the column. The other two included angles of the triangular support plates are fixed by abutment plates, and elastic plates are fixed on the abutment plates.

[0010] Furthermore, the distance between the two triangular support plates matches the height of the inner side of the I-beam, and the side of the elastic plate away from the abutment plate is in contact with the side of the I-beam.

[0011] Furthermore, a baffle is fixed at one end of the pull sleeve near the column, and the baffle abuts against the abutment.

[0012] Furthermore, one end of the pull plate has a first bend that is welded and fixed to the pull sleeve, and the other end of the pull plate has a second bend. The second bend and the column are fixed together with bolts through holes No. 2 and No. 6.

[0013] Furthermore, the I-beam has a No. 3 hole, and the sleeve has a No. 5 hole, which is fixed to the No. 3 hole by bolts.

[0014] Furthermore, the right-angle connecting plate is provided with two sets of No. 7 holes, one set of which is fixed to the No. 1 hole on the corner plate and the column by bolts, and the other set of which is fixed to the No. 4 hole on the I-beam by bolts.

[0015] This utility model has the following beneficial effects:

[0016] This utility model effectively lengthens the spacing between holes 1 and 2, as well as holes 3 and 4, by using a pull sleeve and a pull plate, avoiding the connection holes being too concentrated and affecting the strength of the steel structure, while ensuring the connection strength.

[0017] This utility model provides a support frame between adjacent I-beams, which supports all the I-beams on the same height plane of the column. When one of the I-beams is subjected to a horizontal force, the force can be distributed to the other I-beams under the action of the support frame, effectively improving the horizontal compressive strength. At the same time, the elastic plate in the support frame provides a certain buffering force, further improving the compressive strength.

[0018] 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

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Please see Figure 1 - Figure 4 As shown, this utility model is a connection structure between weldless steel components, including a column 1 and several I-beams 2. The column 1 is arranged vertically, and the I-beams 2 are vertically connected to the column 1. A tie sleeve 3 is fitted on the outside of the I-beam 2. The upper end of the tie sleeve 3 is fixedly installed to the column 1 through a tie plate 4. A support frame 5 is provided between adjacent I-beams 2 to support each other. The support frame 5 also abuts between the tie sleeve 3 and the column 1.

[0029] Specifically, the support frame 5 includes two triangular support plates 51 that are distributed parallel to each other. Right-angle connecting plates 52 are fixed at the right angles of the two triangular support plates 51 and are in contact with the column 1. The other two included angles of the triangular support plates 51 are fixed by abutment plates 53, and elastic plates 54 are fixed on the abutment plates 53.

[0030] Furthermore, the distance between the two triangular support plates 51 matches the height of the inner side of the I-beam 2. That is, the top surface of the upper triangular support plate 51 is in contact with the upper inner side of the I-beam 2, and the bottom surface of the lower triangular support plate 51 is in contact with the lower inner side of the I-beam 2, forming mutual support. The side of the elastic plate 54 away from the abutment plate 53 is in contact with the side of the I-beam 2. The support frame 5 is in contact with the side of the I-beam 2 through the abutment plate 53. Then, under the elastic action of the abutment plate 53, it can play a certain buffering role when the I-beam 2 is subjected to horizontal force.

[0031] Specifically, a baffle 31 is fixed at one end of the pull sleeve 3 near the column 1. The baffle 31 abuts against the abutment plate 53. In use, after two adjacent pull sleeves 3 are fixed to the column 1 and the I-beam 2 through the pull plate 4, the support frame 5, which is triangular in shape, is located between the two adjacent baffles 31, indirectly connecting the adjacent I-beams 2. The stability of the triangle is used to strengthen the horizontal connection stability of the adjacent I-beams 2.

[0032] Specifically, one end of the pull plate 4 has a first bend 41 that is welded and fixed to the pull sleeve 3, and the other end of the pull plate 4 has a second bend 42. The second bend 42 and the column 1 are fixed with bolts through holes 12 and 421. In this embodiment, the first bend 41 and the second bend 42 are vertically distributed. Then, the pull plate 4, the support frame 5, and the column 1 form a triangular structure. The pull plate 4 is fixed to the I-beam 2 through the pull sleeve 3, thereby using the stability of the triangle to make the column 1 and the I-beam 2 stably connected.

[0033] Specifically, the I-beam 2 has a No. 3 hole 21, and the pull sleeve 3 has a No. 5 hole 32, which is fixed to the No. 3 hole 21 by bolts. In this embodiment, the No. 3 hole 21 and the No. 4 hole 22 are far apart, so their impact on the strength of the I-beam 2 is smaller than if they were very close. Moreover, the connection position is closer to the middle of the I-beam 2, so the lifting effect and support are better.

[0034] Furthermore, two sets of No. 7 holes 521 are respectively opened on the two sides of the right-angle connecting plate 52. One set is fixed to the corner plate 6 and the No. 1 hole 11 on the column 1 by bolts, and the other set is fixed to the I-beam 2 by bolts. More specifically, one set of bolts passes through one side of the right-angle connecting plate 52 and then through the No. 7 hole 521 and the No. 1 hole 11. After locking, the corner plate 6, the support frame 5 and the column 1 are fixed. The other set of bolts passes through the corner plate 6 and the No. 4 hole 22. After locking, the corner plate 6 is fixed to the I-beam 2, supporting the connection between the column 1 and the I-beam 2.

[0035] It is understandable that this utility model uses a pull sleeve and a pull plate to lengthen the spacing of each connecting hole, avoiding the holes being too concentrated and affecting the strength of the steel structure, while ensuring the reliability of the connection; and by setting a support frame between adjacent I-beams, the I-beams at the same height support each other, dispersing the local horizontal force to the overall structure, effectively improving the compressive strength; the elastic plate in the support frame also provides a buffering effect, further enhancing the compressive strength of the structure.

[0036] One specific application of this embodiment is:

[0037] S1. The right-angle connecting plate 52 on the support frame 5 is attached to the column 1, and one side of the corner plate 6 is attached to the right-angle connecting plate 52. The corner plate 6 and the support frame 5 are fixed to the column 1 by bolts. All the support frames 5 are installed in sequence.

[0038] S2, the baffle 31 faces the column 1 and is fitted over the outside of the I-beam 2. The pull sleeve 3 and the pull plate 4 are fixed to the I-beam 2 by bolts through hole 32 (No. 5) and hole 21 (No. 3). The I-beam 2 moves along the gap between two adjacent support frames 5 until it abuts against the column 1. The support frame 5 enters the second bend 42 inside the I-beam 2 and abuts against the column 1. The abutment plate 53 abuts against the baffle 31. The other side of the corner plate 6 is fixed to the I-beam 2 by bolts through hole 22 (No. 4). The pull plate 4 is fixed to the column 1 by bolts through hole 421 (No. 6) and hole 12 (No. 2).

[0039] Following step S2, fix the remaining I-beams 2 to column 1 in sequence, resulting in the final connection as shown below. Figure 1 As shown, the end of the elastic plate 54 away from the abutment plate 53 is in abutting state with the inner side of the I-beam 2.
