Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building technology, specifically relating to a prefabricated beam-column structural unit. Background Technology

[0002] With the development of technology, prefabricated building structures have gradually come into people's view. Prefabricated building structures are widely used in house construction due to their advantages such as speed, convenience and low cost, including prefabricated walls, beams and columns.

[0003] In related prior art, such as Chinese Patent No. CN220768392U, a prefabricated beam-column structural unit is disclosed, which solves the technical problems of large on-site work and long construction period in the existing prefabricated concrete structure. The device includes a column, a beam, a top steel structure connector, a bottom steel structure connector, and a reinforcing column. The bottom steel structure connector is pre-embedded at the bottom of the column, and supporting steel bars are pre-embedded inside the column. The top steel structure connector is pre-embedded at the top of the column. The sidewall of the top steel structure connector is connected to the beam. The top steel structure connector on one column is connected to the bottom steel structure connector on another column by bolts and nuts, or by a reinforcing column.

[0004] However, in actual use, since the beams and columns are connected by welding, their positions cannot be adjusted after connection. Furthermore, the columns do not have structures or components for positioning the beams, making the positioning of the beams during welding and installation quite complicated. Workers need to have precise control over the position of the beams, which increases the difficulty of construction and is not conducive to practical use. Utility Model Content

[0005] The present invention aims to provide a prefabricated beam-column structural unit to solve the problem mentioned above of the difficulty in installing existing prefabricated beams.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated beam-column structural unit, comprising...

[0007] The column connector includes a connecting square tube, a flange plate, a first I-beam and a limiting post. The flange plates are fixed at both ends of the connecting square tube, and a column is installed on the side of the flange plate away from the connecting square tube. The first I-beam and the limiting post are both fixed to the side wall of the connecting square tube.

[0008] The beam connector includes a connecting sleeve and a mounting plate. The connecting sleeve has a sliding cavity inside, and a first I-beam is slidably engaged with the sliding cavity. The mounting plate is fixed to the outer wall of the connecting sleeve and is slidably fitted onto a limiting post. A limiting nut is threaded onto the limiting post and abuts against the side of the mounting plate away from the connecting square tube. A beam body is fixed to the side of the connecting sleeve away from the connecting square tube.

[0009] The principle and effects of this technical solution:

[0010] 1. By fixing the first I-beam and the limiting post to the connecting square tube in advance, the welding position deviation caused by inconvenient positioning and poor positioning accuracy during later installation is avoided. The beam can be quickly installed by the cooperation of the connecting sleeve and the first I-beam, which improves the installation efficiency and accuracy and reduces the installation difficulty. In addition, the limiting nut connects to the limiting post, so that the connecting sleeve can be stably abutted against the connecting square tube, preventing the connecting sleeve from slipping off the first I-beam.

[0011] 2. The columns are connected by column connectors, which reduces the difficulty of column forming and ensures that the beams will not damage the column structure during installation, thus ensuring the strength and stability of each part.

[0012] The present invention is further configured such that: a first lug is fixed on the side of the first I-beam away from the connecting square tube, a first connecting rod is slidably inserted into the connecting sleeve, the first connecting rod is slidably inserted into the first lug, and a first nut is threaded onto both ends of the first connecting rod, the first nut abutting against the outer wall of the connecting sleeve.

[0013] The principle and effect of this technical solution: The first connecting rod slides into the first lug and the connecting sleeve, so that even if the limit nut is loose, the first I-beam cannot be separated from the connecting sleeve, which improves the connection stability between the connecting sleeve and the first I-beam. In addition, the setting of the first nut prevents the first connecting rod from falling off the connecting sleeve.

[0014] The present invention is further configured such that: the column connector also includes a top rod and a column core; the bottom of the column has an insertion hole and a slot; the top rod and the column core are both fixed to the flange plate located above; the top rod is adapted to the insertion hole; the column core is adapted to the slot; a second connecting rod is slidably inserted on the column; the second connecting rod is slidably inserted with the column core; a second nut is threaded onto both ends of the second connecting rod; the second nut abuts against the outer wall of the column; and the bottom of the column is welded to the top surface of the flange plate located above.

[0015] The principle and effect of this technical solution are as follows: By cooperating with the top rod and the insertion hole, and cooperating with the column core and the slot, the lateral pressure borne by the column connector after it is connected to the bottom of the upper column can be distributed by the top rod and the column core, thereby reducing the strength of the lateral pressure that the connection needs to withstand. Furthermore, the insertion limit of the column core by the second connecting rod prevents the column core from detaching from the column, ensuring the stability of the connection between the column core and the column. The limit of the second nut prevents the second connecting rod from detaching from the column, thus facilitating the assembly of the upper column onto the lower column connector. In addition, the welding setting further strengthens the connection strength between the column connector and the column.

[0016] The present invention is further configured such that: the interior of the column has a reinforcing bar, the top of the reinforcing bar extends out of the column, and the reinforcing bar is slidably inserted into the flange plate located below, and a fourth nut is threaded on the reinforcing bar, the fourth nut abutting against the top surface of the flange plate located below.

[0017] The principle and effect of this technical solution: By sliding the steel bar and the flange plate together, and by restricting the flange plate with the fourth nut, the column connector and the column body can be easily disassembled and assembled. The steel bar can also provide lateral bearing pressure to the column connector, thereby enhancing the connection strength at the joint.

[0018] The present invention is further configured such that: the column connector also includes a second I-beam, the top of the column has a relief groove, and the second I-beam is slidably inserted into the relief groove.

[0019] The principle and effect of this technical solution: By setting up the I-beam and the relief groove, when the column connector is installed on the column, the I-beam and the relief groove can abut against each other to exert lateral pressure on the column connector, thereby strengthening the connection strength between the column connector and the column and improving the stability of the device during use.

[0020] The present invention is further configured such that: the bottom of the second I-beam has a third lug, a third connecting rod is slidably inserted into the side wall of the column, the third connecting rod is slidably inserted into the third lug, and a third nut is threaded onto both ends of the third connecting rod, the third nut abutting against the outer wall of the column.

[0021] The principle and effect of this technical solution: By inserting the third lug into the third connecting rod, the third lug cannot slide up and down relative to the third connecting rod, thereby further improving the connection strength between the column connector and the column. At the same time, even if the fourth nut is loose, the column connector and the column can remain stable when encountering vibration. Furthermore, the setting of the third nut prevents the third connecting rod from falling off the column.

[0022] The present invention is further provided with ribs between the connecting square tube and the flange plate.

[0023] The principle and effect of this technical solution: The ribs can enhance the ability of the connecting square tube to withstand lateral pressure, thereby improving the strength of the column connector. Attached Figure Description
