Description

Technical Field

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

[0002] The existing prefabricated steel structure support system mainly consists of foundation short columns and steel columns. The foundation short columns are made of poured concrete, with anchor bolts pre-embedded before pouring. A base plate is welded to the bottom of the steel column, and through holes are made in the base plate. To fix the steel column and foundation short columns, the steel column is first hoisted. Workers move the steel column to align the through holes in the base plate with the anchor bolts. After alignment, the steel column is moved downwards until the anchor bolts pass through the through holes in the base plate. Then, high-strength bolts are used to fix the foundation short columns and steel columns.

[0003] Due to the large weight and volume of the steel columns and the large number of anchor bolts, aligning the anchor bolts with the through holes is quite difficult. To address the problems in existing technologies, we propose a prefabricated steel structure support assembly. Utility Model Content

[0004] This utility model addresses the problems in the prior art by providing a prefabricated steel structure support component, which is achieved through the following technical solution: A prefabricated steel structure support component includes a foundation short column and a steel column. The foundation short column is pre-embedded with anchor bolts during casting. A base plate is welded to the bottom of the steel column. The base plate has through holes corresponding to the anchor bolts. The anchor bolts are threaded with fastening nuts for fixing the base plate. A shear key is welded to the lower end face of the base plate. Support columns are pre-embedded in the foundation short column. Two sets of support columns are symmetrically arranged. A positioning guide component that cooperates with the shear key is detachably connected to the support column. The two ends of the positioning guide component are respectively set on the two support columns.

[0005] The present invention is further configured as follows: the shear key is made of I-beam; the positioning and guiding assembly includes a support platform and guide columns; two sets of guide columns are arranged in parallel, and the gap between the two guide columns forms a guide channel; the cross-section of the guide column is rectangular; the two parallel sidewalls of the guide column are respectively attached to the two parallel flanges of the shear key; the web of the shear key moves downward along the guide channel between the two guide columns; a positioning plate is fixedly connected to the lower end face of the guide column; the lower end face of the positioning plate is fixedly connected to the positioning protrusion; the support column is stepped; the support platform is provided with a first positioning hole adapted to the support column and a second positioning hole adapted to the positioning protrusion; the positioning plate is provided with a third positioning hole adapted to the support column.

[0006] The present invention is further configured such that the upper ends of the side walls of the two guide columns that are close to each other are arranged in an arc shape.

[0007] The present invention is further configured such that: a threaded hole is provided on the support column, and a fastening bolt for the base plate is threadedly connected to the threaded hole.

[0008] In summary, the beneficial technical effects of this utility model are as follows: The shear key is larger than the anchor bolt and there is only one. It is easier to use the shear key for guidance and positioning. In addition, the shear key is not easily deformed. Using the shear key for guidance and positioning can also avoid the direct installation of the steel column, which would cause the anchor bolt to collide and deform, thus affecting the installation of the steel column.

[0011] The present invention will be further described in detail below with reference to the accompanying drawings.

[0012] like Figure 1-3 As shown, this utility model discloses a prefabricated steel structure support component, including a foundation short column 1 and a steel column 2. Anchor bolts 3 are pre-embedded in the foundation short column 1. A base plate 4 is welded to the bottom of the steel column 2, and through holes corresponding to the anchor bolts 3 are opened on the base plate 4. Anchor bolts 3 are threadedly connected to fastening nuts 5 for fixing the base plate 4. A shear key 6, made of I-beam, is welded to the lower end face of the base plate 4. Support columns 7 are pre-embedded in the foundation short column 1, and two sets of support columns 7 are symmetrically arranged. A positioning guide component 8, which cooperates with the shear key 6, is detachably connected to the support column 7. The two ends of the positioning guide component 8 are respectively set on the two support columns 7. The shear key 6 is larger than the anchor bolt 3 and there is only one, making it easier to guide and position using the shear key 6. Furthermore, the shear key 6 is not easily deformed; using the shear key 6 for guidance and positioning also avoids the direct installation of the steel column 2, which could cause the anchor bolts 3 to collide and deform, affecting the installation of the steel column 2.

[0013] The positioning and guiding assembly 8 includes a support platform 81 and guide posts 82. Two sets of guide posts 82 are arranged in parallel, and the gap between the two guide posts 82 forms a guiding channel. The cross-section of the guide post 82 is rectangular. The two parallel sidewalls of the guide post 82 are respectively fitted to the two parallel flanges of the shear key 6 for positioning. A positioning plate 83 is fixedly connected to the lower end face of the guide post 82, and the lower end face of the positioning plate 83 is fixedly connected to the positioning protrusion 84. The support post 7 is stepped. The support platform 81 has a first positioning hole 85 that matches the support post 7 and a second positioning hole 86 that matches the positioning protrusion 84. The positioning plate 83 has a third positioning hole 87 that matches the support post 7. To facilitate the placement of the web of the shear key 6 into the guiding channel between the two guide posts 82, the upper ends of the sidewalls of the two guide posts 82 that are close to each other are arc-shaped. Before installing steel column 2, first place support platform 81 on support column 7, then place guide column 82 on support platform 81, forming a gap between the two guide columns 82. Then hoist steel column 2, and the web of shear key 6 extends between the two guide columns 82 and continues to move downward. When anchor bolt 3 extends into the through hole of base plate 4 and is flush with the upper end surface of base plate 4, the positioning guide assembly 8 has completed the positioning and guiding task. There is still a certain gap between shear key 6 and positioning plate 83. At this time, the positioning guide assembly 8 is removed from support column 7. The specific steps for removing positioning guide assembly 8 are as follows: 1. First, move the two guide columns 82 vertically upward to disengage the positioning protrusion 84 from the second positioning hole 86, and remove the guide column 82; 2. Finally, move support platform 81 vertically upward to disengage support column 7 from the first positioning hole 85, and remove support platform 81. Positioning guide assembly 8 can be reused.

[0014] The support column 7 has a threaded hole 71, and the threaded hole 71 is threadedly connected to a fastening bolt 9 for the base plate 4.

[0015] In the attached diagram, the component located below the base plate is the leveling nut, and the components located above the base plate, from top to bottom, are the washer, the fastening nut, and the anti-locking nut. Additionally, after the foundation short columns and steel columns of this application are fixed, secondary pouring is required.
