Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a prefabricated beam and column that is easy to install. Background Technology

[0002] Currently, in the field of prefabricated building technology, most existing columns and beams are assembled and connected by welding. Welding connection method results in long on-site construction time, high labor intensity for workers, and low work efficiency.

[0003] Alternatively, the columns and beams can be bolted to the connecting seat, which has structural defects. The beams are unstable during use, causing them to easily shift on the connecting seat. At the same time, the support mechanism is unstable during use, causing it to loosen.

[0004] For example, Chinese patent CN219411289U discloses a beam-column joint connection structure for prefabricated buildings, including columns and beams. One side of the column has an insertion slot, and one end of the beam is connected to an insertion block that matches the insertion slot. The end of the beam is connected to one side of the column by inserting the insertion block into the insertion slot. A first reinforcing bolt is connected through the side of the column, perpendicularly penetrating the column and the insertion block. L-shaped reinforcing plates are symmetrically connected to the side of the column and on both sides of the insertion slot. This invention has a simple structure, facilitates quick installation and disassembly, guides the beam to be quickly inserted into the column, prevents misalignment between the beam and the column, ensures a more stable and robust beam-column joint connection in both longitudinal and transverse directions, and improves the overall stability of the beam-column joint connection structure.

[0005] However, the connection structure cannot change the installation height of the crossbeam according to specific circumstances, which is inconvenient to use. Utility Model Content

[0006] The purpose of this utility model is to provide an easy-to-install prefabricated beam-column system to solve the problem mentioned in the background art that the connection structure cannot change the installation height of the beam according to specific circumstances, resulting in inconvenience in use.

The connecting block is slidably installed inside the sliding groove. The connecting frame and the longitudinal beam are fixed by the cooperation of the loading and unloading bolts and the adjusting holes of different heights inside the longitudinal beam. The height of the connecting frame is adjusted by cooperating with the loading and unloading bolts.

[0009] Preferably, the longitudinal beam has a positioning hole on the inner surface of the slide groove, and the connecting block has a groove on the side near the positioning hole. A spring pin is fixedly connected inside the groove. The spring pin matches the positioning hole and is connected inside the positioning hole. The positioning hole and the adjustment hole are at the same height. By inserting the spring pin into positioning holes of different heights, the mounting bolt can be better aligned with the adjustment hole.

[0010] Preferably, a washer is connected to the outer surface of the mounting bolt, and the washer is located on the side of the mounting nut near the connecting frame. The washer can prevent the mounting bolt from loosening.

[0011] Preferably, a crossbeam loading and unloading device is provided on the right side of the connecting frame;

[0012] The crossbeam loading and unloading device includes a guide post, a limiting spring, a limiting block, and a limiting groove. The guide post is fixedly connected above the limiting block and slidably connected to the upper right side of the connecting frame. The limiting spring is sleeved on the outer surface of the guide post and located inside the connecting frame. The limiting block is slidably connected to the right side inside the connecting frame. The limiting groove is opened on the upper left side of the crossbeam. The shape and size of the limiting block match the internal shape and size of the limiting groove so that it can be precisely inserted into the limiting groove to prevent the crossbeam from shaking. The crossbeam is fixed by the cooperation of the limiting spring, the limiting block, and the limiting groove.

Rotating the knob drives the gear to rotate, thereby moving the rack and the locking strip to disengage the locking strip from the locking block, allowing the reinforcing block to move freely.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This easy-to-install prefabricated beam and column uses mounting bolts and nuts to fix the connecting frame and longitudinal beam. The height of the connecting frame can be adjusted by adjusting the mounting bolts with different height adjustment holes inside the longitudinal beam. The positioning hole and the adjustment hole are at the same height. The mounting bolt can be better aligned with the adjustment hole by inserting a spring pin into the positioning hole at different heights. The shim can prevent the mounting bolt from loosening.

[0019] 2. This easy-to-install prefabricated beam-column system uses a combination of limit springs, limit blocks, and limit grooves to fix the crossbeam. Pulling the guide column allows the crossbeam to be removed for replacement and maintenance. The connecting frame is supported and reinforced by the combination of a reinforcing cylinder and a reinforcing block. The reinforcing block is prevented from moving into the reinforcing cylinder by the combination of a locking block and a locking strip. Turning the knob drives the gear to rotate, which in turn drives the rack and locking strip to move, causing the locking strip to disengage from the locking block, allowing the reinforcing block to move freely.
