Description

Technical Field

[0001] This utility model belongs to the field of building steel structure technology, and in particular relates to a building steel structure node component. Background Technology

[0002] Steel structure refers to a building form that uses steel as the primary structural material, mainly composed of steel columns, steel beams, steel plates, and reinforcing bars. These components are connected together by welding, bolting, or riveting to form a stable structural system. During the construction of steel structures, joint members are needed to connect the steel components.

[0003] Chinese utility model patent with announcement number CN222909030U discloses a prefabricated steel structure node that avoids excessive pressure concentration, reduces screw breakage, greatly improves the load-bearing capacity of the beam, and enhances the overall reliability during long-term use.

[0004] A search revealed that the aforementioned steel structure node components, with the intercepting rods installed on the inner side of the steel structure columns, present construction difficulties when the columns are long. Furthermore, it hinders the tightening of the steel structures, resulting in poor connection tightness and weak support. Therefore, there is an urgent need to improve existing building steel structure node components and provide a new type of building steel structure node component. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a building steel structure node component that is reasonably designed, simple in structure, easy to construct, and can improve the tightness of steel structure connections and provide stronger support, thereby solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A steel structure node component for building includes a first I-beam and a second I-beam. The first I-beam and the second I-beam are located at opposite ends of a support component and are perpendicular to each other. Multiple sets of positioning components are symmetrically installed on the end of the second I-beam closest to the first I-beam. Limiting brackets are symmetrically fixed to the outer wall of the side of the first I-beam closest to the second I-beam. Two limiting brackets are located on the inner sides of the front and rear ends of the second I-beam, respectively. Positioning grooves are provided at both the upper and lower ends of the limiting brackets. Multiple long screws are inserted between the two limiting brackets and the second I-beam, and each long screw has two movable nuts.

[0008] In a preferred embodiment, the second I-beam has first through holes at equal intervals along the vertical direction at the end closest to the first I-beam, and the limiting bracket has second through holes that correspond one-to-one with the plurality of first through holes.

[0009] In a preferred embodiment, the first through hole and the second through hole have the same diameter, and both ends of the long screw are provided with threaded sections for installing movable nuts.

[0010] In a preferred embodiment, the support assembly includes connecting plates, fastening bolts, and diagonal braces. There are two connecting plates, which are respectively fixedly installed on the outer walls of the first and second I-beams on the side closest to each other by fastening bolts. A diagonal brace is fixedly installed between the two connecting plates.

[0011] In a preferred embodiment, the diagonal brace is a hollow steel structure.

[0012] In a preferred embodiment, the positioning component includes a fixing block, a receiving cavity, a positioning block, a fixing nut, and an internal hexagon bolt. The fixing block is embedded and fixed inside the second I-beam near the end of the first I-beam. The fixing block has a receiving cavity inside, and the positioning block is slidably engaged in the receiving cavity. A fixing nut is embedded at one end of the fixing block, and an internal hexagon bolt is threaded into the fixing nut. One end of the internal hexagon bolt extends into the receiving cavity and is connected to the positioning block bearing.

[0013] In a preferred embodiment, one end of the positioning block is engaged and inserted into the positioning groove, and both the positioning block and the positioning groove have inclined surfaces with equal slopes on their sides that are close to each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the solution of this utility model:

[0016] Insert one end of the second I-beam between the two limiting brackets and make it abut against the outer wall of the first I-beam. Then, use a tool to control the rotation of the hexagon socket bolt. Under the action of the fixing nut, the hexagon socket bolt can drive the positioning block to move and insert the positioning block into the positioning groove. At this time, as the positioning block enters, it can squeeze the inclined inner wall of the positioning groove, thereby applying a horizontal pushing and pulling force to the second I-beam towards the first I-beam, which can effectively improve the tightness of the connection between the first I-beam and the second I-beam.

[0017] The long screw is passed through the second through hole and the first through hole in sequence, and two movable nuts are installed on the outer sides of both ends of the long screw. The movable nuts are tightened to make them fit tightly against the outer wall of the limit bracket, which facilitates the connection strength between the second I-beam and the limit bracket. Furthermore, the installation of the support components facilitates the support of the second I-beam, which can effectively improve the stability of the steel structure installation.

Detailed Implementation

[0025] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0026] like Figure 1-4As shown, the structural steel node component of this utility model includes a first I-beam 1 and a second I-beam 2. The first I-beam 1 and the second I-beam 2 are located at the two ends of the support component 4 and are perpendicular to each other. Multiple sets of positioning components 5 are symmetrically installed on the end of the second I-beam 2 near the first I-beam 1. Limiting brackets 6 are symmetrically fixed to the outer wall of the side of the first I-beam 1 near the second I-beam 2. The two limiting brackets 6 are located on the inner sides of the front and rear ends of the second I-beam 2, respectively. Positioning grooves 7 are provided at both the upper and lower ends of the limiting brackets 6. Multiple long screws 9 are inserted between the two limiting brackets 6 and the second I-beam 2. Each long screw 9 is provided with two movable nuts 10.

[0027] Based on the above structure, the second I-beam 2 has first through holes 3 at equal intervals along the vertical direction at one end close to the first I-beam 1, and the limiting bracket 6 has second through holes 8 that correspond one-to-one with the multiple first through holes 3.

[0028] In this embodiment, the installation of the second I-beam 2 is facilitated by the setting of the limiting bracket 6.

[0029] Based on the above structure, the first through hole 3 and the second through hole 8 have the same diameter, and both ends of the long screw 9 are provided with threaded sections for installing the movable nut 10.

[0030] In this embodiment, the long screw 9 and the movable nut 10 are used to improve the connection strength between the second I-beam 2 and the limiting bracket 6.

[0031] Based on the above structure, the support component 4 includes a connecting plate 41, a fastening bolt 42, and a diagonal brace 43. There are two connecting plates 41, which are respectively fixedly installed on the outer wall of the first I-beam 1 and the second I-beam 2 on the side that are close to each other by fastening bolts 42. A diagonal brace 43 is fixedly installed between the two connecting plates 41.

[0032] Based on the above structure, the diagonal brace 43 is a hollow steel structure.

[0033] In this embodiment, the two connecting plates 41 are respectively installed on the first I-beam 1 and the second I-beam 2 by fastening bolts 42, so that the second I-beam 2 can be supported by the diagonal brace 43, which can effectively improve the stability of the steel structure installation.

[0034] Based on the above structure, the positioning component 5 includes a fixing block 51, a receiving cavity 52, a positioning block 53, a fixing nut 54, and an internal hexagon bolt 55. The fixing block 51 is embedded and fixed inside the second I-beam 2 near the end of the first I-beam 1. The receiving cavity 52 is opened inside the fixing block 51. The positioning block 53 is slidably engaged in the receiving cavity 52. ​​The fixing nut 54 is embedded at one end of the fixing block 51. The internal thread of the fixing nut 54 is connected to the internal hexagon bolt 55. One end of the internal hexagon bolt 55 extends to the inside of the receiving cavity 52 and is connected to the positioning block 53 by a bearing.

[0035] Based on the above structure, one end of the positioning block 53 is engaged and inserted into the positioning groove 7, and both the positioning block 53 and the positioning groove 7 have inclined surfaces with equal slopes on the sides that are close to each other.

[0036] In this embodiment, the rotation of the internal hex bolt 55 is controlled by a tool, which allows the positioning block 53 to move under the action of the fixing nut 54. The positioning block 53 can press the inclined inner wall of the positioning groove 7, thereby applying a horizontal pushing and pulling force to the second I-beam 2 in the direction of the first I-beam 1, which can effectively improve the connection tightness between the first I-beam 1 and the second I-beam 2.

[0037] The working principle of this utility model is as follows:

[0038] In use, first insert one end of the second I-beam 2 between the two limiting brackets 6 and make it abut against the outer wall of the first I-beam 1. Then, use a tool to control the rotation of the hexagonal socket bolt 55. At this time, under the action of the fixing nut 54, the hexagonal socket bolt 55 can drive the positioning block 53 connected to its bearing to move, and the positioning block 53 moves and inserts into the positioning groove 7. As the positioning block 53 continues to slide, it can squeeze the inclined inner wall of the positioning groove 7, thereby applying a horizontal pushing and pulling force to the second I-beam 2 in the direction of the first I-beam 1, which can effectively improve the tightness of the connection between the first I-beam 1 and the second I-beam 2. Then, pass the long screw 9 through the first through hole 3 and the second through hole 8, and install the two movable nuts 10 on the outer sides of both ends of the long screw 9 respectively. Use a tool to tighten the movable nuts 10 until the movable nuts 10 are tightly fitted against the outer wall of the limiting bracket 6, which can improve the connection strength between the second I-beam 2 and the limiting bracket 6.

[0039] Finally, the two connecting plates 41 are fixedly installed on the first I-beam 1 and the second I-beam 2 respectively by fastening bolts 42, so that the second I-beam 2 can be supported by the diagonal brace 43. This can effectively improve the stability of the steel structure installation. Compared with the existing technology, the steel structure node component has a simple structure, is easier to construct, and can improve the tightness of the steel structure connection and the support strength.

[0040] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
