Description

Technical Field

[0001] This utility model relates to the field of steel-concrete composite column-beam joint connection structure, and more specifically, to a steel-concrete composite column-beam joint connection structure. Background Technology

[0002] Concrete-filled steel tubes (CFST) are load-bearing structural members formed by using steel tubes as an outer framework and filling the interior with concrete. They are generally found in the form of beams and columns in major high-rise and super high-rise buildings, especially columns. Due to the combined restraint of the external steel tubes and stiffeners, the internal concrete exhibits a triaxial stress state during the stress process, which significantly reduces concrete cracking. Furthermore, due to the supporting effect of the internal concrete and the restraint effect of the stiffeners on the inner wall of the steel tube, the buckling of the outer steel tube is effectively reduced under the overall structural stress, thereby achieving excellent load-bearing performance and reliability.

[0003] Beam-column joints are the most important joints in steel structure systems, directly affecting the construction speed and the degree of prefabrication. Therefore, beam-column joints should use high-strength bolts that are easy to operate as much as possible, and the bolts should be arranged to be as easy as possible for workers to tighten on site. However, if a large number of bolts are used, the connection structure of the joint may become loose because the bolt mating process is easy.

[0004] In the prior art, such as the utility model disclosed in authorization announcement number CN217500592U, a connection structure between a steel pipe concrete composite column and a beam is provided, including a steel pipe column main component assembly, a support beam, a support plate, reinforcement parts, and a plate fixing block. The steel pipe column main component assembly includes a support frame plate and a first outer sealing plate. The support frame plate is connected to the first outer sealing plate by a first positioning bolt. An installation slot is provided in the side end face of the support frame plate. The support plate is connected to the end of the support beam. The support plate is inserted into the support frame plate through the installation slot. The end of the support plate is connected to the plate fixing block fixed to the inner side wall of the support frame plate. The end of the support beam is connected to the outer side wall of the support frame plate by two reinforcement parts. A first sealing plate and a second sealing plate are provided in the steel pipe column main component assembly at both ends of the plate fixing block. Concrete mortar is provided in the first sealing plate and the second sealing plate.

[0005] In the aforementioned patent, the main body of the I-beam is fixed by inserting it into the main body of the steel pipe column on one side, and the other side is fixed by a fixing block. Its single-point support is inconvenient, and bolts and bolt rods are set both inside and outside for fastening and fixing. The use of bolts is still very large, and the stability and support after fixing are not good. Utility Model Content

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a connection structure between a steel-concrete composite column and a beam. The main body of the I-beam adopts a through-type design, with its outer end welded and fixed to the surface of the main body of the steel-concrete column. The outer end is fixed by a bend positioning seat, and a wedge block structure is set on the inner side. After the bolts are fixed, the wedge blocks can squeeze and tighten the main body of the I-beam. During installation, it has two-point support, which is stable and reduces the number of threaded fasteners used, thus improving the structural strength and support stability.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A steel-concrete composite column-beam joint connection structure includes a steel pipe column body. The outer surface of the steel pipe column body has I-beam slots distributed on both the left and right outer surfaces. An I-beam body slides through the inner surface of the I-beam slots of the steel pipe column body. A notch is provided on the outer end of one side of the I-beam slot of the steel pipe column body, surrounding the outer end of the I-beam slot. A corner positioning seat is fixedly connected to the outer surface of the steel pipe column body. A wedge is fixedly connected to the inner end of the seat. The outer surface of the wedge is tightly pressed against the inner surface of the main body of the steel pipe column, and the inner end surface of the wedge is tightly pressed against the outer surface of the main body of the I-beam. The main body of the I-beam adopts a through-type design, and its outer end is welded and fixed to the surface of the main body of the steel pipe column. Its outer end is fixed by a bend positioning seat, and a wedge structure is set on the inner side. After the bolts are fixed, the wedge can press and tighten the main body structure of the I-beam. During installation, it has two-point support, which is stable and reduces the number of threaded fasteners used, improves the structural strength, and provides stable support.

[0009] Furthermore, one side of the angled positioning seat is fixedly connected to the outer surface of the main body of the steel pipe column by a first bolt.

[0010] Furthermore, the other side of the angled positioning seat is fixedly connected to the outer surface of the I-beam body by a second bolt and nut.

[0011] Furthermore, the first bolts are distributed and fixedly connected to the outer surface of the angle positioning seat in four groups.

[0012] Furthermore, the second set of four bolts is distributed and fixedly connected to the surface of the angled positioning seat and the I-beam body.

[0013] Furthermore, the wedge adopts a trapezoidal block structure, and its outer surface is closely attached to the inner surface of the main body of the steel pipe column.

[0014] Furthermore, the surface of the main steel pipe column is provided with a wedge groove, and the outer surface of the wedge block is tightly fitted to the inner surface of the wedge groove.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) The main body of the I-beam adopts a through-type design. Its outer end is welded and fixed to the surface of the main body of the steel pipe column. Its outer end is fixed by the angle positioning seat, and the inner side is set with a wedge block structure. After the bolt is fixed, the wedge block can squeeze and press the main body of the I-beam. It is supported at two points during installation, which is stable and reduces the number of threaded fasteners used. The structural firmness is improved and the support is stable.

A notch 4 is provided on the outer end of one side of the I-beam slot 2, surrounding the outer end of the I-beam slot 2. An angled positioning seat 5 is fixedly connected to the outer surface of the steel column body 1. A wedge 6 is fixedly connected to the inner end of the seat 5. The outer surface of the wedge 6 is tightly pressed against the inner surface of the steel pipe column body 1, and the inner end surface of the wedge 6 is tightly pressed against the outer surface of the I-beam body 3. The I-beam body adopts a through-type design, and its outer end is welded and fixed to the surface of the steel pipe column body. Its outer end is fixed by a bend positioning seat, and a wedge structure is set on the inner side. After the bolts are fixed, the wedge can press and tighten the I-beam body structure. During installation, it has two-point support, which is stable and reduces the number of threaded fasteners used. The structural strength is improved and the support is stable.

[0026] One side of the angled positioning seat 5 is fixedly connected to the outer surface of the steel pipe column body 1 by the first bolt 7; the fixation is firm.

[0027] The other side of the angled positioning seat 5 is fixedly connected to the outer surface of the I-beam body 3 by the second bolt 8 and nut 9; the angled positioning seat 5 can fix the I-beam body 3 and provide firm support;

[0028] The first bolt 7 is fixedly connected in four groups to the outer surface of the angled positioning seat 5; the second bolt 8 is fixedly connected in four groups to the surface of the angled positioning seat 5 and the I-beam body 3; the distribution is uniform, and the support and installation are stable;

[0029] The wedge 6 adopts a trapezoidal block structure, and its outer surface is tightly attached to the inner surface of the steel pipe column body 1; the surface of the steel pipe column body 1 is provided with a wedge groove, and the outer surface of the wedge 6 is tightly attached to the inner surface of the wedge groove; this facilitates the insertion and fixing of the wedge 6. When its angled positioning seat 5 is locked and fixed in the steel pipe column body 1, the wedge 6 becomes tighter and tighter, and the more it presses against the I-beam body 3, the tighter it becomes.

[0030] In use, an I-beam 2 is provided on the outer surface of the main steel pipe column 1. The I-beam 2 is distributed on the left and right outer surfaces of the main steel pipe column 1. An I-beam 3 slides through the inner surface of the I-beam 2 of the main steel pipe column 1. The I-beam 3, after passing through, is supported on both sides of the inner surface of the main steel pipe column 1, providing stable support. A bend positioning seat 5 is fixedly connected to the outer surface of the main steel pipe column 1. A wedge 6 is fixedly connected to the inner end of the bend positioning seat 5. The outer surface of the wedge 6 is tightly pressed against the inner surface of the main steel pipe column 1, and the inner end surface of the wedge 6 is tightly pressed against the outer surface of the I-beam 3. The bend positioning seat 5 is fixedly connected to the outer surface of the main steel pipe column 1 on one side by a first bolt 7, ensuring a secure fixation. The bend positioning seat 5 is fixedly connected to the outer surface of the I-beam 3 on the other side by a second bolt 8 and a nut 9. The angled positioning seat 5 can fix the I-beam body 3, providing firm support. During fixing, the wedge 6 adopts a trapezoidal block structure, and its outer surface can be tightly attached to the inner surface of the steel pipe column body 1. The surface of the steel pipe column body 1 is provided with a wedge groove, and the outer surface of the wedge 6 is tightly attached to the inner surface of the wedge groove. This facilitates the insertion and fixing of the wedge 6. When the angled positioning seat 5 is locked and fixed in the steel pipe column body 1, the wedge 6 becomes tighter and tighter, pressing the I-beam body 3 more tightly. Furthermore, a notch 4 is provided on the surface of the I-shaped groove 2 on one side of the outer end of the steel pipe column body 1. The notch 4 is set around the outer end of the I-shaped groove 2. After installation, welding can be performed along the notch 4 to weld and fix the steel pipe column body 1 and the I-beam body 3. This improves installation stability and provides firm support (a triangular rib plate is welded and fixed on the surface of the angled positioning seat 5, which can be used to improve the stability).
