Description

Technical Field

[0001] This utility model relates to a steel connector column base leveling device for prefabricated frames. It is applicable to the field of building structure technology. Background Technology

[0002] Precast concrete frame structures with steel joints combine the advantages of steel and concrete structures, enabling immediate load-bearing and continuous construction during the main structure's construction, significantly improving construction speed. In actual construction, after placing the steel joints on the foundation embedded parts, subsequent precast components can be fixedly connected to the foundation embedded parts by connecting the steel joints. However, during column base construction, to meet assembly requirements, the steel joints are sometimes installed detached from the foundation embedded parts. When connecting the steel joints back to the foundation embedded parts, leveling the steel joints is crucial because it relates to the installation of subsequent precast components. This leveling can easily accumulate construction errors, affecting the progress of subsequent structural installation. Utility Model Content

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0024] Example 1 is a leveling device for the steel connector column base of a prefabricated frame. In this example, it has: The frame structure 3 is installed on the foundation embedded part 1 by anchor bolts 14. When the steel connector 2 is arranged on the foundation embedded part 1, the frame structure 3 is fitted on the steel connector 2. A leveling structure is arranged on the frame structure 3. The frame structure 3 has threaded holes, and leveling bolts 10, which are threaded into these holes, are installed on the frame structure 3. The leveling bolts 10 are arranged perpendicular to the axis of the steel connector 2. Leveling bearing platforms 17, also perpendicular to the axis of the steel connector 2, are provided on the side walls of both sides of the steel connector 2. The leveling bolts 10 are respectively positioned at corresponding positions at both ends of the leveling bearing platforms 17. Thus, when the foundation embedded part 1 is poured, anchor bolts 14 are pre-embedded in the foundation embedded part 1, fixing the anchor bolts 14 to the foundation embedded part 1. When the frame structure 3 is arranged on the foundation embedded part 1, it is convenient to install the frame structure 3 onto the foundation embedded part 1 using the anchor bolts 14. After the frame structure 3 is placed on the foundation embedded part 1, when the steel connector 2 is placed on the foundation embedded part 1, the frame structure 3 can play a guiding and supporting role for the steel connector 2. At this time, the leveling bolt 10 on the frame structure 3 is located at the contact position with the leveling bearing 17 on the steel connector 2. The four leveling bolts 10 are located around the steel connector 2. At this time, by turning the leveling bolts 10, the extension of the leveling bolts 10 on the frame structure 3 can be adjusted to facilitate the support of the steel connector 2 after the steel connector 2 is leveled.

[0025] Example 2 is a leveling device for the column base of a prefabricated frame steel connector. Based on Example 1, in this example, the frame structure 3 is composed of two first channel steels 4 and two second channel steels 5 spliced ​​together. The two first channel steels 4 are arranged in parallel, and the two second channel steels 5 are connected between the two first channel steels 4. The second channel steels 5 and the first channel steels 4 are connected by a fastening mechanism. The webs of both the first channel steels 4 and the second channel steels 5 face the steel connector 2. Thus, the fastening mechanism facilitates the assembly and disassembly of the frame structure 3. After the steel connector 2 is connected to the foundation embedded part 1, the first channel steels 4 and second channel steels 5 can be separated by removing the fastening mechanism, allowing for disassembly.

[0026] In this embodiment, the fastening mechanism includes an angle steel 6. A first mounting hole is formed on the first leg of the angle steel 6, and a second mounting hole is formed on the web of the first channel steel 4. A first bolt 7 is mounted on the first leg of the angle steel 6. A first nut 8, threadedly engaged with the first bolt 7, is mounted on the end of the first bolt 7 that passes through the first mounting hole and the second mounting hole. The second leg of the angle steel 6 can contact the web of the second channel steel 5. The angle steel 6 on the first channel steel 4, in conjunction with the angle steel 6 between the two second channel steels 5, clamps the second channel steel 5 and the steel connector 2. Thus, when the first bolt 7 is installed in the first mounting hole on the first leg of the angle steel 6, the end of the first bolt 7 passes through the second mounting hole on the web of the first channel steel 4. By installing the first nut 8 on the end of the first bolt 7 extending outside the first channel steel 4 and tightening it, the angle steel 6 is fixedly connected to the first channel steel 4. When the steel connector 2, the first channel steel 4, and the second channel steel 5 are arranged on the foundation embedded part 1, the angle steel 6 on the first channel steel 4, in conjunction with the angle steel 6 between the two second channel steels 5, clamps the second channel steel 5 and the steel connector 2. An installation pad 18 is provided between the first nut 8 and the web of the first channel steel 4.

[0027] In this embodiment, the second mounting hole is arranged along the length of the first channel steel 4. This facilitates adjustment of the mounting position of the second channel steel 5 on the first channel steel 4, allowing the frame structure 3 composed of the first channel steel 4 and the second channel steel 5 to be adapted to steel connectors 2 of different sizes.

[0028] In this embodiment, a second mounting hole is formed on the first flange of the first channel steel 4 that contacts the foundation embedded part 1, arranged perpendicular to the length of the first channel steel 4. Anchor bolts 14 are installed on the foundation embedded part 1, and a first nut 8 that is threadedly engaged with the end of the anchor bolt 14 through the second mounting hole is installed. A connecting washer 12 is provided between the first nut 8 and the first flange. This facilitates the adjustment of the installation position of the first channel steel 4 on the foundation embedded part 1, so that the frame structure 3 composed of the first channel steel 4 and the second channel steel 5 can be adapted to steel connectors 2 of different sizes.

[0029] In this embodiment, the anchor bolt 14 is pre-embedded in the foundation embedded part 1, and a connecting steel bar 15 is pre-embedded in the foundation embedded part 1. The connecting steel bar 15 can contact the inner wall of the steel connector 2, and the end of the connecting steel bar 15 extends out of the foundation embedded part 1. At least two positioning plates 16 are provided in the foundation embedded part 1 along the length direction of the connecting steel bar 15. A first through hole is made on the positioning plate 16 at the position corresponding to the anchor bolt 14, and a second through hole is made on the positioning plate 16 at the position corresponding to the connecting steel bar 15. This ensures that the connecting steel bar 15 is accurately positioned, so that when the steel connector 2 is placed on the foundation embedded part 1, the connecting steel bar 15 is located at the position corresponding to the inner wall of the steel connector 2, which facilitates the welding of the connecting steel bar 15 and the steel connector 2.

[0030] In this embodiment, the ends of the anchor bolt 14 and the connecting steel bar 15 that extend into the foundation embedded part 1 are both bent outwards. This enhances the connection strength between the anchor bolt 14, the connecting steel bar 15, and the foundation embedded part 1.

[0031] In this embodiment, the two flanges on the first channel steel 4 are the first flange and the second flange, respectively. The width of the first flange on the first channel steel 4 closer to the foundation embedded part 1 is greater than the width of the second flange on the first channel steel 4 farther away from the foundation embedded part 1. This enhances the stability of the first channel steel 4 on the foundation embedded part 1 and also facilitates the operation of the nut on the first flange.

[0032] In this embodiment, stiffening ribs 11 are provided between the first flange and the second flange of the first channel steel 4, and anchor bolts 14 and fastening mechanisms are arranged between the two stiffening ribs 11. This enhances the bending strength of the first channel steel 4.

[0033] In this embodiment, a leveling nut 9 is welded to the second flange of the first channel steel 4. A through hole is formed on the second flange at a position corresponding to the leveling nut 9. The leveling nut 9 is threadedly engaged with the leveling bolt 10. Thus, by tightening the leveling bolt 10 through the threaded engagement of the leveling bolt 10 and the leveling nut 9, the leveling bolt 10 can move up and down. During the downward movement, the leveling bolt 10 can pass through the through hole on the second flange of the first channel steel 4.
