Description

Technical Field

[0001] The utility model belongs to the field of steel structures, and in particular relates to an inserted column foot installation and positioning device for a steel structure. Background Art

[0002] The method for embedded rigid column foot anchor bolts in steel structure and steel-concrete composite structure buildings is consistent, that is, adding column piers below the bottom surface of the foundation to bury the column foot anchor bolts to complete the installation and positioning of the steel column, but the positioning accuracy is not high, which seriously affects the construction progress.

[0003] The patent application with announcement number CN214940344U discloses a positioning device for embedded column bases of steel structures, including: a steel column, a positioning plate, a support plate and a column base anchor bolt. The bottom of the steel column is vertically connected to the positioning plate, and the support plate is provided vertically below the positioning plate. There are two column base anchor bolts, and the two column base anchor bolts are arranged at intervals, and the upper ends pass through the support plate and the positioning plate in turn and are fixed by fasteners. A positioning block is provided on the lower surface of the positioning plate, and a positioning groove is provided on the upper surface of the support plate. When the positioning plate and the support plate are fully aligned, the positioning block is inserted into the positioning groove. Beneficial effects: reducing the construction difficulty during the embedding of the column base anchor bolts, quickly realizing the positioning and installation of the steel column, and having good installation stability.

[0004] However, the above prior art has the following disadvantages when used:

[0005] The paragraph 0026 of the above-mentioned document describes that “according to the positioning of the column foot anchor bolts, holes are opened in the positioning plate and the support plate, steel balls are welded to the positioning plate, and the positioning blocks and positioning grooves are arranged to make the positioning plate and the support plate completely correspond to each other. The column foot anchor bolts are passed through the support plate and the positioning plate in turn, and the horizontality is adjusted by fixing nuts arranged at the upper and lower ends of the positioning plate. The column foot anchor bolts and the support plate are embedded as a whole, and the steel balls are passed through the fastening frame arranged on the positioning plate to support and fasten them”. Combined with the attached manual Figure 1 It can be seen that the fastening nuts need to be fixed by column foot anchor bolts, and then the steel column is fixed inside the fastening frame by the fastening nuts. Since the column foot anchor bolts are prone to rotation after being fixed, the steel column may easily shake after the fastening frame is installed.

[0006] Therefore, a steel structure inserted column foot installation and positioning device is proposed to solve the above-mentioned drawbacks. Utility Model Content

[0007] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a steel structure inserted column foot installation and positioning device.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0009] A steel structure inserted column foot installation and positioning device, comprising a support plate, a positioning plate is installed on the upper side of the support plate, a steel column and two fastening nuts are installed on the positioning plate, a threaded rod is rotatably matched at the bottom of the support plate, the threads on both sides of the threaded rod are in opposite directions, a column foot anchor bolt is matched on one side of the fastening nut, and a gear is installed on the column foot anchor bolt;

[0010] Two clamping plates are slidably matched at the bottom of the support plate, one side of the clamping plate is threadedly matched on the threaded rod, and the other side of the clamping plate is meshed with the gear.

[0011] Optionally, two fastening frames are installed on the upper side of the support plate, and a plurality of arc grooves are provided on the steel column, and the inner walls of the arc grooves are fitted on the outer walls of the fastening frames. A guide groove and two first through holes are provided on the support plate, and the column foot anchor bolts are located inside the first through holes. A guide block is installed on one side of the clamping plate, and the guide block is slidably fitted inside the guide groove, and the cross-sections of the guide groove and the guide block are T-shaped.

[0012] Optionally, a threaded hole and a second through hole are provided on one side of the card plate, a tooth groove is provided on the other side of the card plate, the tooth groove meshes with the gear, one end of the threaded rod is threadedly engaged with the threaded hole, a guide rod is provided between the two second through holes, and rubber pads are installed on the guide rod and the threaded rod, which facilitates guiding the guide rod in the sliding direction of the card plate through the second through hole.

[0013] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0014] The clamping plate is set so that it can slide under the action of the threaded rod. Since the threads on both sides of the threaded rod are in opposite directions, the two clamping plates slide away from each other, and the column foot anchor bolts are fixed by the clamping plate, thereby reducing the problem of shaking of the column foot anchor bolts after the fastening frame is installed.
