Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a structure for horizontally connecting prefabricated columns. Background Art

[0002] Prefabricated columns refer to columns that are pre-processed in a factory, usually made of concrete or other materials. These columns are directly installed into the building structure at the construction site, which can improve construction efficiency and ensure the quality and accuracy of the columns. Prefabricated columns are usually used to support buildings or as part of the building structure.

[0003] Since existing prefabricated columns are usually assembled by welding steel bars, the overall installation is slow and the work efficiency is low. At the same time, when bolts are used for reinforcement support, the existing device cannot make a corresponding judgment on the tightness of the bolts. Once some bolts are not tightened, it is easy to become a subsequent safety hazard. However, the existing device has not made improvements to the above problems, and the overall practical effect is good. Utility Model Content

In addition, the installation of the mounting card plate outside the positioning bolts is further combined with the setting of the positioning bolts. Once the positioning bolts are not tightened or screwed in misaligned, the protruding part will directly cause the installation card plate to be unable to be installed inside the installation groove. Therefore, when installing the card plate, the staff can directly make a basic judgment on whether the positioning bolts are screwed in place, which is convenient for timely correction and adjustment of the positioning bolts that are not installed properly. In addition, the design of sealing and protecting the limiting bolts with the installation card plate makes it difficult for the limiting bolts to be eroded by wind and rain and rusted to affect their fastening and supporting effect, and the overall comprehensive practical effect is strong.

After the first prefabricated column 1 and the second prefabricated column 2 are installed, it is first necessary to use a special plug to seal the through groove 33 leaking out from the side of the first prefabricated column 1 and the second prefabricated column 2. It is noted here that the first prefabricated column 1 and the second prefabricated column 2 are only for illustration. When multiple prefabricated columns are spliced ​​together, it is only necessary to seal the through groove 33 leaking out on the outermost side. After the sealing is completed, the filling material is injected into the interior of the through groove 33 through the grouting holes 34 located at the bottom of the same group. When the filling material leaks out through the grouting holes 34 at the upper end, the grouting holes 34 where the filling material leaks out are sealed in turn until all the grouting holes 34 are sealed. Finally, after the filled filling material is cured, the effect of cured connection is achieved for multiple prefabricated columns.

[0024] The first reinforcing ribs 31 are arranged horizontally at equal intervals, and the second reinforcing ribs 32 are arranged vertically at equal intervals, and the side outer wall of the first reinforcing ribs 31 is connected to the side outer wall of the second reinforcing ribs 32; the first reinforcing ribs 31 and the second reinforcing ribs 32 are arranged alternately to achieve the effect of strengthening the support connection of the overall internal structure of the prefabricated column;

Please note that the filling needs to be carried out through the grouting holes 34 at the lower end. Then, when the interior of the through groove 33 is full, it will overflow through the grouting holes 34 at the upper end. After overflowing, the grouting holes 34 can be promptly sealed with plugs.

[0026] The positioning and installation mechanism 4 includes a limiting T-shaped strip 41, a limiting T-shaped groove 42 and a first thread groove 43. The side outer wall of the second prefabricated column 2 located at the top is provided with a limiting T-shaped strip 41, and the side outer wall of the first prefabricated column 1 located at the top is provided with a limiting T-shaped groove 42. The limiting T-shaped strip 41 and the limiting T-shaped groove 42 are slidingly installed. The side outer wall of the limiting T-shaped strip 41 is provided with first thread grooves 43 at equal intervals. The side outer wall of the first prefabricated column 1 located at the position of the first thread groove 43 is provided with placement grooves 44 at equal intervals, and the side outer wall of the first prefabricated column 1 located at the position of the placement groove 44 is provided with a second thread groove 45. The opening diameter of the first thread groove 43 is equal to the opening diameter of the second thread groove 45.

The first and second prefabricated columns 1 and 2 are installed by threading, and the positioning bolts 46 are arranged inside the placement grooves 44; when the first prefabricated column 1 and the second prefabricated column 2 need to be docked and installed, the first prefabricated column 1 needs to be installed to the specified position first, and then the limiting T-shaped strip 41 on the outside of the second prefabricated column 2 is clamped into the limiting T-shaped groove 42 inside the first prefabricated column 1 from top to bottom, so that the preliminary assembly of the first prefabricated column 1 and the second prefabricated column 2 is completed, and when the limiting T-shaped strip 41 moves to the bottom end of the limiting T-shaped groove 42, the first thread groove 43 and the second thread groove 45 coincide with each other, and then the positioning bolts 46 are passed through the placement grooves 44 on the side of the first prefabricated column 1 through the second interference grooves 53 and screwed into the first interference grooves 51, so that the secondary locking installation of the first prefabricated column 1 and the second prefabricated column 2 is completed;

[0027] The protective sealing mechanism 5 includes a first interfering card slot 51, a mounting slot 52, and a second interfering card slot 53. The first interfering card slot 51 is symmetrically provided on the side outer wall of the limiting T-shaped strip 41 located at the first threaded slot 43. The side outer wall of the first prefabricated column 1 located at the placement slot 44 is provided with an mounting slot 52. The inside of the mounting slot 52 is symmetrically provided with a second interfering card slot 53. The inside of the mounting slot 52 is provided with a mounting card plate 54.

The first interfering card slot 51 and the second interfering card slot 53 are equal in shape and size, and the second interfering card slot 53 and the second interfering card slot 53 are symmetrically provided with a mounting card plate 54. The slot 53 and the interference clamping column 55 are installed in a clamping manner; when the first prefabricated column 1 and the second prefabricated column 2 are spliced ​​and installed, you only need to pick up the installation clamping plate 54 and pass the interference clamping columns 55 on both sides of it through the second interference slot 53 to the inside of the first interference slot 51. It should be noted that if the above-mentioned positioning bolts 46 are not tightened properly or are misaligned, the protruding part of the positioning bolts 46 will make it impossible for the installation clamping plate 54 to be installed in the inside of the installation slot 52. Only when the positioning bolts 46 are installed as required, can the installation clamping plate 54 be normally installed in the inside of the installation slot 52.

[0028] When the utility model is in use, when it is necessary to dock and install the first prefabricated column 1 and the second prefabricated column 2, it is first necessary to install the first prefabricated column 1 to the specified position, and then clamp the limiting T-shaped strip 41 on the outside of the second prefabricated column 2 into the limiting T-shaped groove 42 inside the first prefabricated column 1 from top to bottom, so that the preliminary assembly of the first prefabricated column 1 and the second prefabricated column 2 is completed. When the limiting T-shaped strip 41 moves to the bottom end of the limiting T-shaped groove 42, the first thread groove 43 and the second thread groove 45 coincide with each other, and then the positioning bolt 46 is passed through the placement groove 44 on the side of the first prefabricated column 1 through the second interference The slot 53 is screwed into the inside of the first interference slot 51, and the secondary locking installation of the first prefabricated column 1 and the second prefabricated column 2 is completed. Then the installation card plate 54 is picked up and the interference columns 55 on both sides are inserted into the inside of the first interference slot 51 through the second interference slot 53. It should be noted that if the above-mentioned positioning bolts 46 are not tightened properly or are misaligned, the protruding part of the positioning bolts 46 will make it impossible for the installation card plate 54 to be installed into the inside of the installation slot 52. Only when the positioning bolts 46 are installed as required, can the installation card plate 54 be normally installed into the inside of the installation slot 52.

[0029] Here, the first reinforcing rib 31 and the second reinforcing rib 32 need to be embedded and installed inside the first prefabricated column 1 when it is manufactured, so as to strengthen the overall structural connectivity of the prefabricated column. After the first prefabricated column 1 and the second prefabricated column 2 are installed, it is first necessary to use a special plug to block the through groove 33 leaking out from the side of the first prefabricated column 1 and the second prefabricated column 2. It is noted here that the first prefabricated column 1 and the second prefabricated column 2 are only for illustration. When multiple prefabricated columns are spliced ​​together, it is only necessary to block the through groove 33 leaking out on the outermost side. After the blocking is completed, the filling material is injected into the interior of the through groove 33 through the grouting holes 34 located at the bottom of the same group. When the filling material leaks out through the grouting holes 34 at the upper end, the grouting holes 34 where the filling material leaks out are blocked in turn until all the grouting holes 34 are blocked. Finally, after the filled filling material is solidified, the effect of solidified connection is achieved for multiple prefabricated columns.
