Description

Technical Field

[0001] The present application relates to the technical field of prefabricated steel structure connection, and specifically discloses a prefabricated steel structure node. Background Art

[0002] Steel structure is a structure made of steel materials. It is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates. Prefabricated steel structure buildings are prefabricated buildings composed of the above steel components.

[0003] Traditional prefabricated steel structure buildings are connected in a combined manner through bolt welding and end plate connections between prefabricated steel components.

[0004] In the process of installing steel beams corresponding to steel columns, the existing connection structure of steel structure nodes only installs the ends of the steel beams on the side walls of the steel columns through connecting plates or connecting frames, without shielding and protecting the connections between the steel beams and the steel columns. This is especially true for the connection between I-beams and I-beam columns. The connection between the end face of the I-beam and the side wall of the I-beam column has a long span, and water is easily attached to the side of the I-beam, so the connection is prone to rust during long-term use.

[0005] Therefore, in view of this, the inventor provides a prefabricated steel structure node to solve the above problems. Utility Model Content

[0006] The utility model aims to solve the problem that the connection structure of the traditional assembled steel structure node does not provide shielding and protection for the connection between the steel beam and the steel column, and the connection will rust during long-term use.

[0007] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides an assembled steel structure node, including an I-beam column, an I-beam beam and a connecting structure for connecting and fixing the I-beam beam and the I-beam column, the connecting structure including a bottom connecting plate connected to the I-beam column by bolts and a steel frame fixed to the outside of the bottom connecting plate, the end of the I-beam beam extends into the inner side of the steel frame and is connected by bolts, and the inner sides of the steel frame are also connected by bolts with side support structures for supporting the inner walls of the I-beam on both sides.

[0008] Furthermore, end connection parts are extended outwardly from both ends of the steel frame, and the I-beam extends into the inner end of the steel frame and is connected to the end connection part by bolts.

[0009] Furthermore, the width of both sides of the end connection part is smaller than the width of both sides of the steel frame end, and arc grooves for resisting deformation are formed at the connection between both sides of the end connection part and the steel frame end.

[0010] Furthermore, a wedge block for auxiliary support of the I-beam is fixedly connected between the end of the steel frame and the bottom connecting plate.

[0011] Furthermore, the bottom connecting plate inside the steel frame is also fixedly connected to engaging blocks which can be respectively inserted into the inside of both sides of the I-beam, and a sliding chamber for accommodating the end of the I-beam extending therein is formed between the inner wall of the steel frame and the engaging blocks.

[0012] Furthermore, the side support structure includes a side connecting plate connected to the inner side of the steel frame by bolts, a U-shaped steel plate fixed to the inner side of the side connecting plate and attached to the side wall of the I-beam, and the U-shaped steel plate is connected to the I-beam by bolts.

[0013] Furthermore, the length of the U-shaped steel plate is longer than the length of the side connecting plate.

[0014] Furthermore, a support plate is fixedly connected between the U-shaped steel plate and the side connecting plate.

[0015] The principle and effect of this scheme are:

[0016] Compared with the prior art, the utility model uses a steel frame to accommodate the extended end of the I-beam, fixes the I-beam by bolting the steel frame to the I-beam, and fixes it to the I-beam column with a bottom connecting plate and bolts. The steel frame is used to accommodate and protect the end of the I-beam, which solves the problem of the connection structure of the traditional assembled steel structure node, which does not shield and protect the connection between the steel beam and the steel column, and the connection will rust during long-term use.

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0020] The reference numerals in the drawings of the specification include: I-beam column 1, I-beam beam 2, bottom connecting plate 3, internal connecting plate 4, steel frame 5, end connection part 6, wedge block 7, support plate 8, U-shaped steel plate 9.

[0021] An assembled steel structure node, for example Figure 1 As shown:

[0022] It includes an I-beam column 1, an I-beam beam 2 and a connection structure for connecting and fixing the I-beam beam 2 and the I-beam column 1. In this embodiment, one I-beam beam 2 is installed on both sides of the I-beam through the connection structure.

[0023] The connection structure includes a bottom connecting plate 3 and a steel frame 5 welded to the outside of the bottom connecting plate 3. When the bottom connecting plate 3 is installed, the inner end face fits the outer wall of one side of the I-beam column 1, and the bottom connecting plate 3 around the steel frame 5 is fixed to the fitted side wall of the I-beam column 1 by inserting bolts. Internal connecting plates 4 are also installed on the inner walls on both sides of the I-beam column 1 corresponding to the side edges of the bottom connecting plate 3. When the bottom connecting plate 3 and the two sides of the I-beam column 1 are bolted, the bolts also penetrate the internal connecting plate 4 and fix the internal connecting plate 4 at the same time, thereby increasing the stability of the bottom connecting plate 3 during subsequent use. The end of the I-beam beam 2 extends into the inside of the steel frame 5, and a side support structure for supporting the inner walls on both sides of the I-beam beam 2 is also installed on the inside of the steel frame 5.

[0024] In this embodiment, the ends of the steel frame 5 are further extended with end connection parts 6, and the ends of the I-beam 2 extending into the inner side of the steel frame 5 are fixed to the end connection parts 6 by bolts. Moreover, the width of the end connection parts 6 is smaller than the width of the ends of the steel frame 5, and arc grooves for anti-deformation are formed at the connection between the ends of the steel frame 5 and the ends of the steel frame 5.

[0025] A wedge block 7 for auxiliary support of the I-beam 2 is fixedly installed between the two end portions of the steel frame 5 and the bottom connecting plate 3 at the same end by welding, and a semicircular groove is also opened on the wedge block 7 located at the corner of the bottom connecting plate 3 and the steel frame 5.

[0026] The bottom connecting plate 3 located inside the steel frame 5 is also welded with engaging blocks that can be respectively inserted into the inside of the two sides of the I-beam 2. The engaging blocks are rectangular blocks that are respectively inserted into the inside of the two sides of the I-beam 2. A sliding chamber for accommodating the end of the I-beam 2 to extend therein is formed between the inner wall of the steel frame 5 and the engaging blocks. When the end of the I-beam 2 slides into the steel frame 5, the steel frame 5 and the rectangular blocks jointly position and clamp the end of the I-beam 2.

[0027] The side support structure includes a side connecting plate fixedly connected to the inner side of the steel frame 5 by bolts, a U-shaped steel plate 9 welded to the inner side of the side connecting plate and attached to the side wall of the I-beam 2, and the two end faces of the U-shaped steel plate 9 are respectively fixedly connected to the two inner end faces of the I-beam 2 by bolts.

[0028] In this embodiment, the length of the U-shaped steel plate 9 is longer than that of the side connecting plate. The bolted connection portion between the U-shaped steel plate 9 and the I-beam beam 2 is located on a section of the side connecting plate extending from the U-shaped steel plate 9, and a support plate 8 is welded between the bending part of the U-shaped steel plate 9 and the side wall of the side connecting plate.

[0029] In this embodiment, all the bolted connection parts are supplied with current during the bolt connection process to achieve bolted connection between the plates, between the I-beam 2 and the plates, and between the I-beam column 1 and the plates.

[0030] When the utility model is used, the steel frame 5 is used to accommodate the extended end of the I-beam 2, the I-beam 2 is fixed by bolting the steel frame 5 to the I-beam 2, and the bottom connecting plate 3 is used to cooperate with the bolts to fix it on the I-beam column 1. The steel frame 5 is used to accommodate and protect the end of the I-beam 2, which solves the problem of the connection structure of the traditional assembled steel structure node, which does not shield and protect the connection between the steel beam and the steel column, and the connection will rust during long-term use.
