Description

Technical Field

[0001] The utility model relates to the technical field of fixing tie bars, in particular to a fixing device for embedded tie bars in a filled wall. Background Technique

[0002] Tie bars are an important type of structural steel bars in construction engineering, mainly playing the role of enhancing the stability and seismic performance of walls. Tie bars are steel bars arranged at certain intervals along the height of the wall in a masonry structure, usually connected to bricks or blocks in the wall to form an integral tie system. Enhancing the stability of the wall: Tie bars can effectively connect the bricks or blocks in the wall together, improve the integrity and stability of the wall, and prevent the wall from cracking, collapsing, etc. when subjected to external forces. Improving the seismic performance of the wall: In the event of natural disasters such as earthquakes, tie bars can effectively transmit seismic forces, enabling the bricks or blocks in the wall to bear forces together, improving the seismic performance of the wall, and reducing the damage to buildings caused by earthquakes.

[0003] For example, the Chinese patent with the publication number CN219808496U discloses a fixing device for embedded tie bars in a filled wall, which relates to the technical field of building construction. The fixing device includes: an end formwork, side formworks, and a U-shaped plate; the end formwork and the two side formworks enclose the formwork of the filled wall, and the end formwork is provided with an opening at the corresponding position of the tie bar; the splicing end of the U-shaped plate is provided with a semi-circular notch matching the tie bar, and the two U-shaped plates are spliced together to block the opening, and the circular hole formed by the corresponding semi-circular notches of the two U-shaped plates just allows the tie bar to pass through; the U-shaped plate is connected to the side formwork through a tie bolt; the fixing device blocks the opening through the spliced U-shaped plate and provides a circular hole for the tie bar to pass through, which not only does not affect the embedding of the tie bar but also avoids the leakage of slurry at the opening during the pouring process of the filled wall; when removing the formwork, the tie bolt is removed, and the spliced U-shaped plates are separated to expose the opening, and then the end formwork can be easily removed.

[0004] Although the above example can fix the embedded tie bars, in the actual use process, the thicknesses of the embedded tie bars used in different walls are different, and the above example can only be adapted to specific models of embedded tie bars and cannot be adjusted according to the thickness of the embedded tie bars, resulting in certain inconvenience in use.

Then rotate the second screw 46. Under the action of the threaded connection between the second screw 46 and the connecting nut 45, while the two fixing mechanisms 4 approach each other, drive the clamping block 51 to clamp the embedded tie bar 3. And through the setting of the rubber pad 52, the sealing performance between the embedded tie bar 3 and the clamping block 51 can be improved. Then rotate the first screw 42, so that the extrusion plate 43 approaches the surface of the filling wall formwork 1 under the guidance of the guide rod 44, and while extruding it, fix the fixing device to the surface of the filling wall formwork 1. Then the filling wall can be cast. When it is necessary to fix embedded tie bars 3 of different models, only need to replace a suitable clamping block 51, then the fixing device can be adapted to the embedded tie bar 3, making it more convenient to use.

[0026] Embodiment 2

Both ends of the U-shaped fixing member 41 are threadedly connected with a first screw rod 42. One end of the first screw rod 42 is rotatably connected with a pressing plate 43. Both ends of the pressing plate 43 close to one side of the first screw rod 42 are fixedly connected with guide rods 44. One side of the U-shaped fixing member 41 is fixedly connected with a connecting nut 45. The inside of the connecting nut 45 is threadedly connected with a second screw rod 46. An installation groove 47 is arranged on the side of the U-shaped fixing member 41 away from the connecting nut 45. Two sets of fixing mechanisms 4 are provided.

[0028] In this embodiment, by rotating the first screw rod 42, the pressing plate 43 is guided by the guide rods 44 to approach the surface of the filling wall formwork 1. While pressing it, the fixator is fixed to the surface of the filling wall formwork 1. Subsequently, the filling wall can be cast. When it is necessary to fix embedded tie bars 3 of different models, only the appropriate clamping block 51 needs to be replaced, so that the fixator can be adapted to the embedded tie bars 3, making it more convenient to use.

Subsequently, the second screw rod 46 is rotated. Under the action of the threaded connection between the second screw rod 46 and the connecting nut 45, while the two sets of fixing mechanisms 4 approach each other, the clamping block 51 is driven to clamp the embedded tie bar 3. Through the arrangement of the rubber pad 52, the sealing performance between the embedded tie bar 3 and the clamping block 51 can be improved.

[0032] Next, the working principle of the filling wall embedded tie bar fixator will be specifically described.

[0033] As Figures 1-4As shown in the figure, when fixing the embedded tie bar 3, after fixing the clamping block 51 into the installation groove 47 through the assembly bolt 53, insert the installation groove 47 into the preset hole opened on the surface of the infilled wall formwork 1, and place the embedded tie bar 3 in the groove on the surface of the clamping block 51. Then rotate the second screw rod 46. Under the action of the threaded connection between the second screw rod 46 and the connection nut 45, while the two fixing mechanisms 4 approach each other, drive the clamping block 51 to clamp the embedded tie bar 3. And through the setting of the rubber pad 52, the sealing performance between the embedded tie bar 3 and the clamping block 51 can be improved. Then rotate the first screw rod 42, so that the pressing plate 43 approaches the surface of the infilled wall formwork 1 under the guidance of the guide rod 44. While pressing it, fix the fixator to the surface of the infilled wall formwork 1. Then the infilled wall can be cast. When it is necessary to fix embedded tie bars 3 of different models, only need to replace the appropriate clamping block 51, then the fixator can be adapted to the embedded tie bar 3, making it more convenient to use.
