Description

Technical Field

[0001] The utility model belongs to the technical field of assembled column bases, and in particular relates to an assembled column base connection structure for an indoor exhibition hall frame. Background Art

[0002] The steel structure exhibition hall is mainly used to display the manufacturing level of steel structure products. At the same time, the frame structure exhibited in the exhibition hall needs to have a good viewing effect while ensuring the structural safety. As the existing technology, there are two common ways to connect the column bases of the structural columns in the exhibition hall. The first is the embedded parts solution, and the second is the post-anchor bolt solution. The former embedded parts solution has complicated procedures and low economic applicability. In the latter, the connecting plate and anchor bolt head used in the anchor bolt are easy to protrude from the ground, which affects the appearance and is easy to trip people. At present, there are anchor bolt connection structures on the market that can hide the connecting plate and anchor bolt head.

[0003] For example, patent application number CN202320854522.2 discloses an assembled column base connection node of an indoor steel exhibition hall frame structure, including a connecting plate and a positioning plate installed on the connecting plate; the anchor bolts pass through the positioning plate and the connecting plate in turn, and penetrate into the ground to fix the positioning plate and the connecting plate to the ground; the lower end of the box-type column is located on the connecting plate, the positioning plate is located in the inner cavity of the box-type column, and the side of the positioning plate is in contact with the inner wall of the box-type column. There is only a connecting plate between the lower end of the column and the ground, which occupies a smaller exhibition hall viewing space. In addition to the connecting plate, the column base connectors including the positioning plate and anchor bolts are not exposed, which is not only beautiful but also does not affect visitors' walking. The utility model also has the outstanding characteristics of convenient assembly and short construction period.

[0004] In the prior art, the positioning plate and the anchor bolt connector are hidden by the setting of the box-type column, which improves the aesthetics and does not affect the walking of visitors. However, there are still certain shortcomings during use: first, the exhibition hall frame needs to be disassembled after the product display is completed. Although the prior art hides the anchor bolt connector through the box-type column, it is not sealed. External gas and moisture can still corrode the anchor bolt connector. Therefore, it is easy to corrode after long-term use, affecting the subsequent disassembly and maintenance. Secondly, the prior art welds the connecting plate and the box column, which is not conducive to subsequent disassembly and replacement. If welding technology is not used, the positioning plate and the connecting plate in the prior art cannot support and fix the box column, and the applicability is low. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the utility model provides an indoor exhibition hall frame assembled column foot connection structure. The utility model provides a sealing end cover, a positioning plate and a sealing ring groove, so that the anchor bolt connector can be well sealed after installation, effectively avoiding the corrosion of the end, facilitating subsequent disassembly and maintenance, and in combination with a support block and a plurality of anti-slip sleeves, the box-type column and the fixing plate can be well supported and fixed without welding, so that the frame as a whole can be quickly disassembled and transported after use.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an indoor exhibition hall frame assembled column foot connection structure, including a fixing plate and a positioning plate, the fixing plate is provided with a positioning plate on the upper end surface, the positioning plate is provided with a positioning disk on the upper end surface, a plurality of second mounting holes are evenly arranged on the positioning plate and the positioning disk along the circumferential direction, a first mounting hole is arranged on the end surface of the fixing plate below the second mounting hole, fixing bolts are arranged in the second mounting hole and the first mounting hole, a sealing ring groove is arranged on the end surface of the positioning plate on the outside of the positioning disk, a sealing end cover is arranged on the sealing ring groove, the sealing end cover can cover a plurality of fixing bolts to complete the sealing treatment, and a support block is sleeved on the outside of the sealing end cover. The arrangement of the sealing end cover and the sealing ring groove allows the ends of the plurality of fixing bolts to be wrapped and sealed, effectively avoiding the occurrence of moisture corrosion on the ends.

[0007] Preferably, a box-shaped column is arranged on the end surface of the fixing plate outside the positioning plate, and a plurality of the box-shaped columns are connected to the tops of beams. The plurality of box-shaped columns cooperate with the beams to form a frame.

[0008] Preferably, grooves are provided on the outer end surfaces of the positioning plate and the support block, so that the positioning plate and the support block can support and fix the bottom of the box-shaped column.

[0009] Preferably, the outer wall surface of the support block is provided with a plurality of opening holes with an outer circular surface on one side being open, each of the opening holes is filled with an anti-slip sleeve, and a plug rod is slidably provided at the center of the anti-slip sleeve. The provision of the anti-slip sleeve and the plug rod can effectively improve the supporting and fixing effect of the support block on the bottom end face of the box-type column, so that the bottom of the box-type column can be fixed without welding.

[0010] Preferably, a connecting plate is provided on the top end surface of the plug rod, so that the plug rod can be quickly replaced.

[0011] Preferably, a plurality of sealing rings are arranged on the end surface of the sealing end cover in the sealing ring groove. The arrangement of the sealing rings effectively improves the sealing effect of the sealing end cover.

[0012] Preferably, a nut is arranged outside the fixing bolt on the end surface of the positioning plate, and the arrangement of the nut effectively improves the overall stability of the frame.

[0013] In summary, compared with the prior art, the beneficial effects of this solution are:

[0014] The utility model arranges the positioning plate and the sealing end cover as well as the sealing ring groove and the sealing ring, so that after the installation and fixation of the fixing plate, multiple fixing bolts can form a semi-wrapped sealing treatment on the outside of the fixing bolts, effectively blocking the entry of external moisture and avoiding corrosion of the ends of the fixing bolts, making the subsequent frame disassembly easier, allowing the various parts of the frame to be reused, and reducing the cost of use.

[0015] The utility model arranges the sealing end cover and the support block as well as the anti-slip sleeve and the plug rod, so that the sealing end cover can cooperate with the support block to increase the supporting and fixing effect of the box-type column when sealing the fixing bolt, so that the box-type column can be stably supported without the help of welding technology, thereby ensuring the overall stability of the frame, allowing the subsequent frame to be quickly disassembled without wasting materials, thereby improving the practical value.

[0029] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0030] Embodiment 1:

[0031] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig.10 As shown, an assembled column base connection structure for an indoor exhibition hall frame includes a fixing plate 12 and a positioning plate 15. The fixing plate 12 is provided with a positioning plate 15 on the upper end surface, and a positioning plate 20 is provided on the upper end surface of the positioning plate 15. A plurality of second mounting holes 23 are evenly arranged on the positioning plate 15 and the positioning plate 20 along the circumferential direction, a first mounting hole 21 is arranged on the end surface of the fixing plate 12 below the second mounting hole 23, and fixing bolts 13 are arranged in the second mounting hole 23 and the first mounting hole 21. A sealing ring groove 22 is arranged on the end surface of the positioning plate 15 on the outside of the positioning plate 20, and a sealing end cover 14 is arranged on the sealing ring groove 22. The sealing end cover 14 can cover the plurality of fixing bolts 13 to complete the sealing process, and a support block 16 is sleeved on the outside of the sealing end cover 14.

[0032] When the frame needs to be installed, the staff can abut and overlap the fixing plate 12 and the positioning plate 15, and then place the fixing plate 12 at the installation point. In this relationship, the positioning plate 20 is pre-welded to the end face of the positioning plate 15. Therefore, after the fixing plate 12 and the positioning plate 15 are placed, the staff can insert multiple fixing bolts 13 through the holes formed by the second mounting hole 23 and the first mounting hole 21 into the ground, so that the fixing plate 12, the positioning plate 15 and the positioning plate 20 can be fixed to the ground.

[0033] Subsequently, the staff can cover the sealing end cover 14 on the multiple fixing bolts 13, and one end of the bottom of the sealing end cover 14 will be inserted into the sealing ring groove 22 outside the positioning plate 20, so that the multiple fixing bolts 13 with one end abutting against the positioning plate 20 can be sealed, thereby preventing the top end surface of the fixing bolt 13 from being corroded by moisture, so that when the frame is disassembled later, the fixing bolt 13 can be removed smoothly, thereby improving the convenience of disassembly and maintenance.

[0034] After the sealing end cover 14 completes the sealing process, the staff can put the support block 16 on the outside of the sealing end cover 14. In this relationship, multiple outer end faces of the support block 16 are flush with the outer end face of the positioning plate 15, which can assist the positioning plate 15 to improve the supporting and fixing effect on the frame.

[0035] like Figure 1 , Figure 2 , Figure 3 and Fig. 9 As shown, a box-type column 11 is arranged on the end surface of the fixing plate 12 outside the positioning plate 15 , and the tops of the plurality of box-type columns 11 are connected to a crossbeam 10 .

[0036] When the fixing plate 12 and the positioning plate 15 are installed, the staff can insert the box-type column 11 on the outside of the positioning plate 15 and the support block 16. The bottom end surface of the box-type column 11 will be pressed on the top end surface of the fixing plate 12, so that the box-type column 11 is supported and fixed by the outer wall surface of the positioning plate 15 and the outer wall surface of the support block 16. In this relationship, if the frame needs to be permanently fixed, the staff can also weld the box-type column 11 and the fixing plate 12. When the box-type column 11 is completed, the staff can weld the beam 10 to the upper end of the box-type column 11 to complete the frame.

[0037] like Figure 4 , Fig.11 As shown in the fixing plate 12, the outer wall of the support block 16 is provided with a plurality of opening holes 27 with an outer circular surface on one side being open, each opening hole 27 is filled with an anti-slip sleeve 17, and a plug rod 26 is slidably provided at the center of the anti-slip sleeve 17.

[0038] Each opening hole 27 is open on one side of the end face of the support block 16. The anti-skid sleeve 17 filled inside the opening hole 27 is made of elastic and anti-skid rubber material, and the plug rod 26 sliding inside is made of hard metal material. Before the box-shaped column 11 is sleeved on the outside of the support block 16, the staff can insert the anti-skid sleeve 17 and the plug rod 26 into the opening hole 27, so that the outer circular surface of one side of the anti-skid sleeve 17 protrudes onto the outer end face of the support block 16 through the opening of the opening hole 27. At this time, when the box-shaped column 11 is inserted into the outside of the support block 16, multiple anti-skid sleeves 17 are inserted outside. The round surface will be squeezed into contact with the inner wall of the box-type column 11, and multiple anti-slip sleeves 17 will be deformed by pressure in this process, which can fill the contact gap, so that the fixing effect between the box-type column 11 and the support block 16 can be improved, thereby improving the supporting and fixing effect of the assembled box-type column 11. In this relationship, the plug rod 26 can provide the necessary supporting strength for the anti-slip sleeve 17. When the anti-slip sleeve 17 needs to be replaced after long-term use, the staff will pull out the plug rod 26 outward, and the anti-slip sleeve 17 will shrink inward. At this time, the anti-slip sleeve 17 can be quickly removed and replaced.

[0039] like Figure 8 and 10 As shown, a plurality of sealing rings 24 are arranged on the end surface of the sealing end cover 14 in the sealing ring groove 22 .

[0040] When the sealing ring 24 on the bottom of the sealing end cover 14 is inserted into the sealing ring groove 22, it effectively blocks the entry of external gas and moisture. In this relationship, the sealing ring groove 22 sinks into the end face of the positioning plate 15, which can itself perform a wrap-around seal on the bottom of the sealing end cover 14. The sealing ring 24 can effectively improve the sealing effect on the end of the fixing bolt 13.

[0041] like Figure 4 As shown, groove surfaces 25 are provided on the outer end surfaces of the positioning plate 15 and the supporting block 16 .

[0042] The plurality of groove surfaces 25 can contact the inner wall surface of the box-type column 11 when the box-type column 11 is inserted outside the positioning plate 15 and the support block 16, thereby increasing the contact friction and tightness, thereby improving the supporting and fixing effect on the frame.

[0043] like Figure 5 As shown, a nut 19 is arranged outside the fixing bolt 13 on the end surface of the positioning disk 20 .

[0044] The fixing bolts 13 cooperate with the nuts 19 to improve the fixing effect between the fixing plate 12 and the ground, thereby improving the supporting strength of the entire frame.

[0045] Embodiment 2:

[0046] like Figure 4 and Fig.12As shown, an indoor exhibition hall frame assembled column foot connection structure, a connecting plate 18 is arranged on the top end surface of the plug rod 26.

[0047] As a further embodiment, when the plug rod 26 is inserted into the anti-slip sleeve 17, the connecting plate 18 will be pressed on the end face of the plug rod 26. The setting of the connecting plate 18 makes it possible to complete the replacement of the plug rod 26 by only pulling the connecting plate 18, which effectively improves the maintenance efficiency.
