Description

Technical Field

[0001] This utility model relates to the field of cast steel nodes, specifically a new type of prefabricated cast steel node. Background Technology

[0002] A cast steel node is a steel structural connector formed by casting process (usually sand casting or precision casting).

[0003] Chinese patent application number CN202321585157.6 discloses a transversely multi-support cast steel node. The spherical cast steel node has multiple transverse support pipes in its transverse position. The transverse support pipes include two symmetrical main pipes and multiple branch pipes. It can be applied to large-span curved surfaces of double-layer structures. Then, a branch pipe is set at the top of the spherical cast steel node as a top connection, and three branch pipes are set at the bottom as diagonal support to improve the support strength.

[0004] However, most cast steel nodes are large in size and heavy in weight, and are difficult to disassemble. Therefore, they require a lot of manpower and resources for hoisting and transportation, which increases the cost and risk of hoisting and transportation. Therefore, a new type of prefabricated cast steel node is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, most cast steel nodes are large in size and heavy in weight, and are difficult to disassemble. Therefore, they require a lot of manpower and resources for hoisting and transportation, which increases the cost and risk of hoisting and transportation. This utility model proposes a new type of prefabricated cast steel node.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a novel prefabricated cast steel node, including a cast steel body; an assembly component is provided on the outside of the cast steel body, and a support component is connected to the outside of the cast steel body;

[0007] The assembly includes multiple connecting pipes, which are fixedly connected to the outer wall of the cast steel body. A flange is connected to the outside of each connecting pipe. A sealing groove is opened at the outer end of the flange, and a sealing gasket is movably filled inside the sealing groove. Multiple shear keys are fixedly connected inside the flange. A flange is detachably connected to the outer end of the flange via a locking bolt. A cast steel split body is fixedly connected to the outside of the flange. Multiple keyways are opened at the end of the flange near the flange.

[0008] By setting up assembly components to separate the cast steel main body and cast steel sub-units, the number of cast steel sub-units can be adjusted according to the connection requirements of different steel structure beams and columns. Furthermore, during hoisting and transportation, the cast steel main body and cast steel sub-units can be hoisted and transported separately, saving manpower and resources. When assembling the cast steel sub-units, shear keys are inserted into the corresponding keyways, and then flange one and flange two are locked together using locking bolt one. The shear keys and keyways facilitate the positioning of flange one and flange two, and can also transmit shear force, preventing locking bolt one from being sheared. The sealing gasket improves the sealing performance of the connection between flange one and flange two.

[0009] Preferably, the shear key is movably connected to the keyway, and the shear key is adapted to the keyway.

[0010] Preferably, the connecting pipes are arranged at equal intervals, and the locking bolt one is threadedly connected to flange one and flange two.

[0011] Preferably, the support assembly includes a main connecting ring, which is fixedly connected to the outer wall of the cast steel body, and a secondary connecting ring is fixedly connected to the outer wall of the cast steel sub-body.

[0012] By setting up support components, the stability of the connection between the cast steel components and the cast steel body can be improved after the required cast steel components are assembled, thus providing support for the cast steel components.

[0013] Preferably, the outer wall of the main connecting ring is fixedly connected to multiple sets of connecting pieces one, which are arranged at equal intervals, and the outer wall of the secondary connecting ring is fixedly connected to connecting pieces two.

[0014] Preferably, a support rod is detachably connected between the first connecting piece and the second connecting piece by a second locking bolt.

[0015] Preferably, the second locking bolt is threaded to the support rod, and the second locking bolt is threaded to both the first connecting piece and the second connecting piece.

[0016] The advantages of this utility model are:

[0017] 1. This utility model separates the cast steel main body and the cast steel sub-body by setting up assembly components. The number of cast steel sub-body parts can be adjusted according to the connection requirements of different steel structure beams and columns. During hoisting and transportation, the cast steel main body and the cast steel sub-body parts can be hoisted and transported separately, which saves more manpower and material resources. When assembling the cast steel sub-body parts, the shear key is inserted into the corresponding keyway, and then the locking bolt is used to lock flange one and flange two. The shear key and keyway facilitate the positioning of flange one and flange two, and the shear key and keyway can also transmit shear force to prevent the locking bolt one from being sheared. The setting of the sealing gasket can improve the sealing performance of the connection between flange one and flange two.

[0018] 2. By setting up a support component, this utility model can improve the stability of the connection between the cast steel parts and the cast steel body after the required cast steel parts are assembled, and play a supporting role for the cast steel parts. Attached Figure Description

[0028] This application discloses a novel prefabricated cast steel node. (Refer to...) Figures 1-5 A novel prefabricated cast steel node includes a cast steel body 1; an assembly component 2 is provided on the outside of the cast steel body 1, and a support component 3 is connected to the outside of the cast steel body 1.

[0029] Assembly component 2 includes multiple connecting pipes 201, which are fixedly connected to the outer wall of the cast steel body 1. The external connection of the connecting pipes 201 is a flange 202. The outer end of the flange 202 is provided with a sealing groove 203. The sealing groove 203 is movably filled with a sealing gasket 204. Multiple shear keys 205 are fixedly connected inside the flange 202. The outer end of the flange 202 is detachably connected to a flange 207 via a locking bolt 206. The external connection of the flange 207 is a cast steel split body 208. Multiple keyways 209 are provided at the end of the flange 207 near the flange 202.

[0030] By setting assembly component 2, when assembling cast steel component 208, shear key 205 is inserted into the corresponding keyway 209, and then locking bolt 206 is used to lock flange 202 and flange 207. Shear key 205 and keyway 209 facilitate the positioning of flange 202 and flange 207, and shear key 205 and keyway 209 can also transmit shear force to prevent locking bolt 206 from being sheared. The setting of sealing gasket 204 can improve the sealing performance of the connection between flange 202 and flange 207.

[0031] Reference Figures 1-5 The shear key 205 is movably connected to the keyway 209, and the shear key 205 is adapted to the keyway 209.

[0032] Reference Figures 1-5 The connecting pipes 201 are arranged at equal intervals, and the locking bolts 206 are threaded to flanges 202 and 207.

[0033] Reference Figures 1-5 The support component 3 includes a main connecting ring 301, which is fixedly connected to the outer wall of the cast steel body 1, and a secondary connecting ring 302 is fixedly connected to the outer wall of the cast steel split 208.

[0034] By setting the support component 3, the stability of the connection between the cast steel component 208 and the cast steel body 1 can be improved after the required cast steel component 208 is assembled, thus providing support for the cast steel component 208.

[0035] Reference Figures 1-5 The outer wall of the main connecting ring 301 is fixedly connected to multiple sets of connecting pieces 303, which are arranged at equal intervals. The outer wall of the secondary connecting ring 302 is fixedly connected to connecting piece 304.

[0036] Reference Figures 1-5 A support rod 306 is detachably connected between connecting piece 1 303 and connecting piece 2 304 via locking bolt 2 305.

[0038] After locking flange 202 and flange 207 with locking bolt 206, the specific position of cast steel body 208 is determined. Then, support rod 306 can be placed between corresponding connecting piece 303 and connecting piece 304. Finally, lock bolt 305 is used to lock support rod 306 to corresponding connecting piece 303 and connecting piece 304 respectively. Thus, support rod 306 can effectively support cast steel body 1 and cast steel body 208.

[0039] Working principle: When assembling the cast steel split body 208, the shear key 205 is inserted into the corresponding keyway 209, and then the locking bolt 206 is used to lock the flange 202 and the flange 207. The shear key 205 and the keyway 209 facilitate the positioning of the flange 202 and the flange 207, and the shear key 205 and the keyway 209 can also transmit shear force to prevent the locking bolt 206 from being sheared. The setting of the sealing gasket 204 can improve the sealing performance of the connection between the flange 202 and the flange 207.

[0040] After locking flange 202 and flange 207 with locking bolt 206, the specific position of cast steel body 208 is determined. Then, support rod 306 can be placed between corresponding connecting piece 303 and connecting piece 304. Finally, lock bolt 305 is used to lock support rod 306 to corresponding connecting piece 303 and connecting piece 304 respectively. Thus, support rod 306 can effectively support cast steel body 1 and cast steel body 208.
