[0001] This utility model relates to the field of fixed buildings, specifically a prefabricated wall-column connection structure. Background Technology

[0002] Prefabricated wall columns are vertical seismic-resistant components of column structures. They are the main seismic-resistant components of building structures. With the rapid development of the prefabricated construction industry, the connection nodes between prefabricated reinforced concrete frame structures, enclosure wall panels and structural columns are complex and have become a hot topic of concern in the engineering field. They are also an important technical link in promoting the industrialization of prefabricated construction. The safety, reliability and applicability of the connection nodes of prefabricated wall columns determine the quality of building assembly and the progress of construction projects.

[0003] An existing technology has developed a prefabricated wall-column connection structure, in which precast concrete columns and precast concrete wall panels are manufactured in a factory and then assembled on the construction site. Compared with traditional on-site casting, this prefabricated wall-column connection structure requires less on-site casting work, has higher construction efficiency, and a shorter construction period. However, it still has a problem: the connection strength between the precast concrete columns and precast concrete wall panels cannot be guaranteed. Summary of the Invention

The I-beam steel connector is inserted into the installation groove and mutually limited and fixedly assembled with the prefabricated wall column. Limiting clamps for limiting and engaging the I-beam steel connector are slidably provided on both sides of the installation groove.

[0006] Furthermore, a row of U-shaped stirrups is fixedly provided from top to bottom on the connecting surface of the I-beam steel connector, passing through the through groove and inserted into the concrete pouring cavity of the prefabricated wall column. Fixing plates are installed on both sides of the connecting surface of the I-beam steel connector, which are inserted into the fixing slots inside the installation groove.

[0007] Furthermore, the top and bottom of the prefabricated wall column are respectively equipped with an upper sealing cover plate and a lower sealing cover plate. Straight steel bars are fixedly installed on both the upper and lower sealing cover plates, which are inserted into the concrete pouring cavity and mutually limit and abut against the four corners of the inner ring of the U-shaped stirrup.

[0008] Furthermore, the limiting clamp slides within the sliding cavities on both sides of the mounting groove, and the outer walls on both sides of the assembled cavity column are threaded with adjusting screws that are threadedly connected to the threaded holes of the limiting clamp.

[0009] Furthermore, the limiting clamp is driven by the rotation of the adjusting screw thread to slide out from the sliding cavity and insert into the clamping groove of the I-beam steel connector.

[0010] This utility model has the following features and beneficial effects: This utility model connects the wall panel to the prefabricated wall column via an I-beam steel connector, allowing the fixing plate on the I-beam steel connector to be inserted into the fixing slot; simultaneously, the U-shaped stirrups are inserted into the concrete pouring cavity; by adjusting the screw, the limiting clamping plate is inserted into the clamping groove to limit and clamp the I-beam steel connector; the straight steel bar on the sealing cover is inserted into the concrete pouring cavity and mutually limits and abuts against the four corners of the inner ring of the U-shaped stirrups. After the concrete is poured in and cured, the prefabricated wall column and wall panel are connected on site, ensuring the connection strength between the prefabricated wall column and wall panel.

Limiting clamps 5 are provided on both sides of the mounting groove 11 for limiting and locking the I-beam steel connector 7.

[0016] See Figure 1 , Figure 5 As shown, a row of U-shaped stirrups 71, passing through the through groove 13 and inserted into the concrete pouring cavity 14 of the prefabricated wall column 1, is fixedly provided on the connecting surface of the I-beam steel connector 7 from top to bottom. Fixing plates 72, which are inserted into the fixing slots 12 inside the installation groove 11, are installed on both sides of the connecting surface of the I-beam steel connector 7. The I-beam steel connector 7 on the connecting end of the wall panel 8 is placed into the installation groove 11 of the prefabricated wall column 1, so that fixing plates 72, which are inserted into the fixing slots 12 inside the installation groove 11, are installed on both sides of the connecting surface of the I-beam steel connector 7. At the same time, the U-shaped stirrups 71 pass through the through groove 13 and are inserted into the concrete pouring cavity 14 of the prefabricated wall column 1.

[0017] See Figure 2 , Figure 3 As shown, to ensure the connection strength between the precast concrete column and the precast concrete wall panel, an upper sealing cover plate 2 and a lower sealing cover plate 3 are installed at the top and bottom of the precast wall column 1, respectively. Straight steel bars 4 are fixedly installed on both the upper and lower sealing cover plates 2 and 3, which are inserted into the concrete pouring cavity 14 and mutually restrained and abutted at the four corners of the inner ring of the U-shaped stirrups 71.
