Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a connection structure between a steel structure and a building foundation. Background Art

[0002] The connection between steel structure columns and foundations is a very important part of steel structure engineering, which is directly related to the stability and safety of the entire building structure.

[0003] Chinese patent publication CN215715485U discloses a connection structure between a steel structure and a building foundation, and a steel structure building. After aligning an adjustment hole with a first anchor bolt, a connection hole is formed in a connector according to the position of a second anchor bolt. The connector is then moved closer to the building foundation. As the first anchor bolt passes through the adjustment hole, the second anchor bolt also passes through the connection hole. This further improves the stability of the connection between the steel structure and the building foundation, while also preventing the first anchor bolt from sliding relative to the adjustment hole during later construction. Finally, the first anchor bolt is connected to the connector via a first nut, and the second anchor bolt is connected to the connector via a second nut.

[0004] However, when the above solution is used, the second anchor bolt is positioned after the first anchor bolt is penetrated through the adjustment hole, and the connection hole is opened after positioning, which makes the installation of the steel structure inconvenient and inefficient.

[0026] Example 1

[0027] like Figure 1-4 As shown, the present invention proposes a connection structure between a steel structure and a building foundation, comprising a mounting frame 4 arranged in a building foundation 1, bolts 3 connected to a steel structure 2, a connection block 5 and a limit plate 10;

[0028] The mounting frame 4 is installed on the inner side of the building foundation 1, and the top end is flush with the upper end surface of the building foundation 1. The mounting frame 4 is a hexahedron made of welded angle steels. The hexahedron is a kind of cube and cuboid. Due to the characteristics of the angle steel, the middle part of the mounting frame 4 has a cavity, and the six faces have connecting holes 8 connecting to the cavity.

[0029] There are multiple bolts 3, and the multiple bolts 3 are all installed on the inner side of the mounting frame 4, and the top ends extend to the top of the mounting frame 4 and are inserted into the steel structure 2. The bottom end of the steel structure 2 is provided with mounting holes corresponding to 3. Among them, the multiple bolts 3 correspond to the multiple mounting holes of the steel structure 2 one by one, and the diameter of the mounting hole of the steel structure 2 is larger than the diameter of the bolt 3, so that there is a gap when the bolt 3 is installed in the mounting hole of the steel structure 2, thereby improving the convenience of connecting the bolt 3 with the steel structure 2;

[0030] There are multiple connecting blocks 5, each of which is mounted on the inner side of the mounting frame 4 and sleeved on the outer side of the bolt 3 to limit the position of the bolt 3 when in use;

[0031] The limit plate 10 is installed on the outer top end of the mounting frame 4 and covers the bottom end of the steel structure 2. It should be noted that the limit plate 10 is U-shaped, and the limit plate 10 is wrapped around the three edges of the top end of the mounting frame 4. There is a gap between the inner top end of the limit plate 10 and the top end of the mounting frame 4, and the bottom edge of the steel structure 2 is located in the gap between the limit plate 10 and the mounting frame 4, and the inner top end of the limit plate 10 and the top end of the mounting frame 4 are connected to the upper and lower end surfaces of the bottom end of the steel structure 2 so that the bottom end of the steel structure 2 moves between the mounting frame 4 and the limit plate 10 on the building foundation 1 when in use, and slides to a preset position between the mounting frame 4 and the limit plate 10.

[0032] In this embodiment, the connecting blocks 5 are fixedly installed on the inner top and lower ends of the mounting frame 4, and the connecting blocks 5 at the inner top and lower ends of the mounting frame 4 correspond to each other up and down, the bolts 3 are installed in the two connecting blocks 5, and the positions of the bolts 3 are arranged one by one corresponding to the positions of the mounting holes of the steel structure 2. The mounting frame 4 drives the bolts 3 to be prefabricated at the construction site of the building foundation 1, so that when the building foundation 1 is prepared, the material of the building foundation 1 is filled into the middle cavity of the mounting frame 4 through the connecting holes 8, so that the building foundation 1 wraps the mounting frame 4 and the bolts 3, so that the bolts 3 are threadedly connected to the building foundation 1, and the position of the bolts 3 is adjusted. The limit is set to avoid the position of the bolt 3 being offset during installation. During installation, the bolt 3 is removed, and the bottom end of the steel structure 2 is moved between the limit plate 10 and the mounting frame 4 at the top of the building foundation 1, so that the bottom end of the steel structure 2 is installed between the limit plate 10 and the mounting frame 4. At the same time, the limit plate 10 limits the bottom end of the steel structure 2, and the bolt 3 is passed through the limit plate 10 from above the limit plate 10, and the steel structure 2 is inserted into the connecting block 5 on the inner side of the mounting frame 4, and the steel structure 2 is fixed between the mounting frame 4 and the limit plate 10, so that the installation of the steel structure 2 is more convenient and more stable.

[0033] Example 2

[0034] like Figure 3-4 As shown, the utility model proposes a connection structure between a steel structure and a building foundation. Compared with Example 1, in this embodiment, two connecting blocks 5 are a group, and the two connecting blocks 5 are respectively installed on the inner top and bottom ends of the mounting frame 4 along the axial direction of the bolt 3 and are sleeved on the outer side of the bolt 3.

[0035] In an optional embodiment, a threaded hole 9 is provided in the middle of the connecting block 5 . When the connecting block 5 and the bolt 3 are installed in cooperation, the bolt 3 is accommodated in the threaded hole 9 .

[0036] In this embodiment, the bolt 3 is confined on the inner side of the mounting frame 4 by means of connecting blocks 5 installed at the top and bottom ends of the inner side of the mounting frame 4, so that the bolt 3 has multiple supports, and there is a gap between the two connecting blocks 5, so that when the building foundation 1 is filled toward the inner side of the mounting frame 4, the building foundation 1 is wrapped around the outer side of the bolt 3 to further confine the bolt 3, thereby improving the firmness of the vertical connection of the bolt 3.

[0037] Example 3

[0038] like Figure 3-4As shown, the utility model proposes a connection structure between a steel structure and a building foundation. Compared with the first embodiment, in this embodiment, the building foundation 1 is wrapped around the outside of the mounting frame 4 and extends to the inside of the cavity of the mounting frame 4 through the connecting hole 8, so that the cavity of the mounting frame 4 is filled, and the connecting hole 8 at the top of the mounting frame 4 is filled. At the same time, the building foundation 1 on the inside of the mounting frame 4 is connected to the building foundation 1 on the outside of the mounting frame 4 through the connecting holes 8 on the side and bottom of the mounting frame 4, and the mounting frame 4 is embedded in the building foundation 1, so that the mounting frame 4 and the building foundation 1 are connected as a whole, so that the stability of the mounting frame 4 after installation is higher.

[0039] In this embodiment, the mounting frame 4 is prefabricated in the building foundation 1 through the connection holes 8 on the six sides of the mounting frame 4 when the building foundation 1 is prepared, so that the preparation materials of the building foundation 1 are filled into the cavity in the mounting frame 4 through the connection holes 8 on the six sides of the mounting frame 4, and the mounting frame 4 is embedded in the building foundation 1, thereby improving the firmness of the installation of the mounting frame 4.

[0040] Example 4

[0041] like Figure 3 As shown, the present invention proposes a connection structure between a steel structure and a building foundation. Compared with the first embodiment, in this embodiment, a connection plate 6 is provided in the connection hole 8 on the bottom surface of the mounting frame 4. The connection plate 6 is a perforated plate used for allowing the material of the building foundation 1 inside the mounting frame 4 to flow downward through the holes of the connection plate 6 when in use, so that the building foundation 1 inside the mounting frame 4 is connected with the building foundation 1 outside the mounting frame 4 through the holes of the connection plate 6, thereby improving the installation stability of the mounting frame 4.

[0042] The connection holes 8 on the four sides of the mounting frame 4 are each provided with a rib plate 7. The rib plate 7 is in an X-shape and is used to separate the connection holes 8 on the side of the mounting frame 4 into multiple holes when in use, so that the connection holes 8 are in a triangular shape, thereby improving the supporting strength of the mounting frame 4 when in use.

[0043] In this embodiment, by installing the connecting plate 6 in the connecting hole 8 at the bottom end of the mounting frame 4, the contact area between the mounting frame 4 and the building foundation 1 is increased. At the same time, the building foundation 1 on the inner side of the mounting frame 4 is connected to the building foundation 1 on the outer side through the holes on the surface of the connecting plate 6, so that the installation stability of the mounting frame 4 is higher. When the mounting frame 4 is in use, the rib plate 7 divides the connecting hole 8 on the side of the mounting frame 4 into a triangle, thereby improving the supporting strength of the mounting frame 4.

[0044] In summary, when the present invention is in use, the connecting block 5 is fixedly installed on the inner top and lower end of the mounting frame 4, and the connecting blocks 5 at the inner top and lower end of the mounting frame 4 are arranged correspondingly up and down, the bolts 3 are vertically installed in the threaded holes 9 of the two connecting blocks 5, and the mounting frame 4 drives the bolts 3 to be prefabricated at the construction site of the building foundation 1, so that when the building foundation 1 is prepared, the material of the building foundation 1 is filled into the middle cavity of the mounting frame 4 through the connecting hole 8, and there is a gap between the two connecting blocks 5, so that the bolts 3 between the two connecting blocks 5 are exposed and installed in the connecting block 5, so that the building foundation 1 wraps the connecting block 5, the mounting frame 4 and the bolt 3, so that the bolt 3 is threadedly connected to the building foundation 1, and at the same time, the position of the bolt 3 is limited, and the position of the bolt 3 is made to correspond one-to-one with the position of the mounting hole of the steel structure 2, so as to avoid the position of the bolt 3 during installation When the steel structure 2 is offset, the bolt 3 is removed and the bottom end of the steel structure 2 is moved parallel to the limit plate 10 and the mounting frame 4 at the top of the building foundation 1, so that the bottom end of the steel structure 2 is installed between the limit plate 10 and the mounting frame 4. At the same time, the limit plate 10 limits the bottom end of the steel structure 2, and the bolt 3 passes through the limit plate 10 from above the limit plate 10 and the steel structure 2 is inserted into the connecting block 5 on the inner side of the mounting frame 4 to fix the steel structure 2 between the mounting frame 4 and the limit plate 10, making the installation of the steel structure 2 more convenient and more stable. In particular, in the case that the mounting hole of the steel structure 2 does not correspond to the position of the bolt 3, a nut can be welded above the mounting hole of the steel structure 2, and a shorter bolt 3 can be used to abut against the mounting frame 4 to fix the bottom end of the steel structure 2 between the mounting frame 4 and the limit plate 10.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
