DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0028] At present, in the process of building steel structures, the nodes of steel structures are usually connected by bolts. During the connection process, workers need to manually align the steel structures, which makes the connection operation troublesome, and the bolts are prone to loosening after connection, resulting in instability at the nodes, which poses a safety hazard. The steel structure node component provided by the present application makes the steel structure more stable after connection, reduces the need for workers to manually align the steel structures when connecting the existing steel structure nodes, resulting in troublesome operation during connection, and the bolts are prone to loosening after connection, resulting in instability at the nodes, which easily causes unsafe situations, and improves the overall ease of use of the equipment.

[0029] The specific structure of the steel structure node component provided in this application is described in detail below with reference to the accompanying drawings.

[0030] See also Figure 1 The present application provides a steel structure node component, the steel structure includes a steel column 1 and a crossbeam 2, the node component includes at least one stabilizing device 3 and a plurality of locking devices 4; the stabilizing device 3 is fixedly connected to the steel column 1, and the crossbeam 2 is inserted into the stabilizing device 3.

[0031] See also Figure 3 and Figure 4A plurality of fixing rings 31 are provided on the lower surface of the stabilizing device 3, and a through hole 311, a first card slot 312 and a second card slot 313 are provided on the fixing ring 31. The first card slot 312 is a through slot, and the second card slot 313 is a countersunk slot. The first card slot 312 and the second card slot 313 are staggered and evenly distributed around the through hole 311.

[0032] See also Figure 5 The locking device 4 includes a locking column 41 and a locking block 42. The locking block 42 is evenly distributed at one end of the locking column 41 along the circumference of the cylindrical surface of the locking column 41. The position of the locking block 42 corresponds to the position of the first card slot 312. The shape of the locking block 42 is adapted to the first card slot 312. A locking mechanism 43 is provided at the other end of the locking column 41.

[0033] The part where the stabilizing device 3 and the cross beam 2 are inserted into the stabilizing device 3 is provided with a socket that passes through the stabilizing device 3 and the cross beam 2. The locking column 41 is equipped with one end of the locking block 42, which passes through the socket, the through hole 311 and the first slot 312 and then rotates and is engaged in the second slot 313. The other end of the locking column 41 is provided with a locking mechanism 43, and the locking mechanism 43 cooperates with the upper surface of the stabilizing device 3 to lock the cross beam 2.

[0034] When the steel structure node member provided by the present application is in use, the stabilizing device 3 is fixedly connected to the steel column 1, and the fixed connection method can be welding, or a mounting seat is set on the stabilizing device 3, and a mounting hole is opened on the mounting seat, and a mounting hole is opened at a corresponding position on the steel column 1, and the two are fixed by threaded connection. The specific connection method is determined according to the site conditions and the purpose of the steel structure. For example, welding is used for steel structures that do not need to be disassembled for long-term use, and bolt fastening is used for steel structures that need to be disassembled. After the stabilizing device 3 is connected to the steel column 1, the crossbeam 2 is inserted into the mounting port of the stabilizing device 3, and the two are fixed by the locking device 4. Compared with the existing connection method, the present application does not require workers to manually align the crossbeam 2 when in use, and only needs to insert the crossbeam 2 into the corresponding socket on the stabilizing device 3, which is simpler to operate. After the connection is completed, the structure is more stable under the action of the stabilizing device 3 and the locking device 4.

[0035] The steel structure node member provided in the present application can be set at the middle position, corner and edge of the steel structure, and is applicable to various forms of steel structure connections. For example, when the steel structure node member of the present application is set at the middle position, since the four sides of the steel column 1 need to be connected to the crossbeam 2, four stabilizers 3 can be set at this time. When the steel structure node member of the present application is set at the corner position, only two stabilizers 3 need to be set. The number of stabilizers 3 can be set according to the specific construction plan.

[0036] In some embodiments, see Figure 2 , also includes a first auxiliary device 5, which is arranged on the lower surface of the stabilizing device 3, and the first auxiliary device 5 includes two connecting rods 51 and two first steel ropes 52, the two connecting rods 51 are symmetrically arranged on the two side surfaces of the stabilizing device 3 and are rotatably connected with the two side surfaces of the stabilizing device 3, a gear rod 53 is arranged between the two connecting rods 51, and the two first steel ropes 52 are symmetrically arranged on both sides of the stabilizing device 3, one end of the two first steel ropes 52 is connected to the gear rod 53, and the other end of the two first steel ropes 52 is vertically connected to the open end of the stabilizing device 3.

[0037] When in use, the structure formed by the shift rod 53 and the two connecting rods 51 applies an upward supporting force to the cross beam 2, thereby strengthening the connection structure. At the same time, the first steel rope 52 applies an upward pulling force to the shift rod 53, thereby improving the stability of the connection structure.

[0038] In some embodiments, see Figure 6 , and also includes a second auxiliary device 6, which includes a fixing member 61 and a plurality of second steel ropes 62, wherein the fixing member 61 is sleeved on the steel column 1 and fixedly connected to the steel column 1; one end of the second steel rope 62 is connected to the upper surface of the stabilizing device 3, and the other end of the second steel rope 62 is provided with a clamping block 621, and a clamping structure is provided on the fixing member 61, and the clamping block 621 is clamped and matched with the clamping structure.

[0039] The second auxiliary device 6 cooperates with the first auxiliary device 5, and also applies an upward force to the cross beam 2 to prevent the cross beam 2 from moving downward under the action of its own gravity. When in use, the fixing member 61 is fixedly connected to the steel column 1, and the connection method can be welding. The second steel rope 62 is connected to the fixing member 61 by a clamping block 621, which is easy to operate, labor-saving, and improves work efficiency.

[0040] In some embodiments, see Figure 6The clamping structure includes a clamping interface 611, a clamping block 612, a push piece 613 and a push rod 614; the clamping interface 611 is opened on the side of the fixing member 61, the fixing member 61 is a hollow structure, the clamping block 612 is arranged in the inner cavity of the fixing member 61, the push piece 613 is located above the fixing member 61, the lower surface of the push piece 613 is connected to one end of the push rod 614, the other end of the push rod 614 is inserted into the inner cavity of the fixing member 61 and connected to the upper surface of the clamping block 612, and a clamping spring 615 is arranged between the lower surface of the clamping block 612 and the bottom surface of the inner cavity of the fixing member 61.

[0041] The clamping structure provided on the fixing member 61 changes the size of the clamping interface 611 by pushing the pushing member 613 to compress the spring 615, so that the clamping block 621 can be conveniently inserted into the clamping interface 611. This design relaxes the size requirements of the clamping block 621, facilitates manufacturing, and facilitates the removal of the clamping block 621 when maintenance or replacement is required.

[0042] In some embodiments, two positioning blocks 32 are further included. The positioning blocks 32 are arranged inside the stabilizing device 3 to limit the insertion position of the cross beam body 2 .

[0043] In the existing steel structure, the crossbeam body 2 is usually made of I-beam. When the crossbeam body 2 is inserted into the socket of the stabilizing device 3, two positioning blocks 32 are arranged in the socket for better positioning. The distance between the two positioning blocks 32 matches the thickness of the I-beam vertical beam. In addition to the positioning function of the crossbeam body 2, the two positioning blocks 32 can also effectively prevent the crossbeam body 2 from moving in the socket, thereby improving the strength and stability of the structure.

[0044] In some embodiments, see Figure 5 The locking mechanism 43 includes a gasket 431, a spring 432 and an end cap 433. The gasket 431 is mounted on the locking column 41. The end cap 433 is fixedly connected to the locking column 41. The two ends of the spring 432 are fixedly connected to the end cap 433 and the locking column 41 respectively.

[0045] The locking mechanism 43 is installed at one end of the locking column 41. When the installation is completed, the locking mechanism 43 is located on the upper surface of the stabilizing device 3. After the locking block 42 provided at the other end of the locking column 41 is engaged with the second locking groove 313, the gasket 431 applies a downward force to the upper surface of the stabilizing device 3 under the action of the spring 432. Therefore, the locking mechanism 43 cooperates with the locking block 42 to fix the locking device 4.

[0046] In some embodiments, a limiting structure is provided on the lower surface of the fixing ring 31, and the limiting structure includes two limiting rods 314 and a limiting plate 315. The two limiting rods 314 are arranged symmetrically with the axis of the fixing ring 31 as an axis, one end of the two limiting rods 314 is fixedly connected to the lower surface of the fixing ring 31, and the other end of the two limiting rods 314 is fixedly connected to the upper surface of the limiting plate 315. The limiting rods 314 and the limiting plate 315 limit the travel of the locking column 41, making the installation of the locking device 4 more convenient.

[0047] In some embodiments, the number of the first card slots 312 is two, the number of the second card slots 313 is two, the number of the locking blocks 42 is set to two, and the first card slots 312 and the second card slots 313 have the same shape and size.

[0048] In this embodiment, as a preferred example, the two first card slots 312 are symmetrically arranged, and the two second card slots 313 are symmetrically arranged, and the angle between the first card slot 312 and the second card slot 313 is 90°. After the locking column 41 and the locking block 42 pass through the through hole 311 and the first card slot 312, they can be rotated 90° to engage the locking block 42 in the second card slot 313.

[0049] In some embodiments, the diameters of the gasket 431 and the end cap 433 are larger than the diameter of the through hole 311. At this time, the gasket 431 is in contact with the upper surface of the stabilizing device 3 to play a fastening role.

[0050] According to the above technical features, the steel node member provided by the present application is provided with a stabilizing device. When the steel column and the cross beam need to be connected, the stabilizing device is fixedly connected to the steel column, and the cross beam is inserted into the socket provided on the stabilizing device and fixed with a locking device. The locking device includes a locking column and a locking block. The locking block is provided at one end of the locking column. The stabilizing device is provided with a through hole, a first slot and a second slot. The locking column and the locking block pass through the through hole and the first slot. The locking column and the locking block are rotated so that the locking block is clamped in the second slot. At this time, the spring, gasket and end cap provided at the other end of the locking column fix the locking device on the stabilizing device. The steel node member provided by the present application makes the steel structure more stable after connection, reduces the need for workers to manually align the steel structure when connecting the existing steel structure nodes, resulting in troublesome operation during connection, and the bolts are prone to loosening after connection, resulting in instability at the node and easy to cause unsafe conditions, thereby improving the overall ease of use of the equipment.
