The present invention can effectively adjust the height of the connecting plates on both sides, which is convenient for adjusting the height of the steel beam, so that the whole device is suitable for use in sites with various conditions, thereby enhancing the applicability of the whole device, and the positions of the connecting plates on both sides are in a horizontal state, which can make the installed steel beams present an overall horizontal effect, thereby improving the overall aesthetic effect of the equipment.

[0004] The above-mentioned published patents exist when in use:

[0005] 1. It is impossible to disassemble and fix different connection seats, resulting in poor use of the equipment. It is inconvenient to disassemble and assemble the connection seats in time, which wastes human resources. In addition, it is impossible to limit the installed steel beams, which can easily cause the steel beams to shake and affect the stability of use.

[0006] 2. When multiple sets of mounting bases need to be used for assembly at the same time, they cannot be connected and fixed, which makes the mounting bases prone to misalignment, making splicing difficult, the installation cost high, and inconvenient for subsequent disassembly and assembly, affecting construction efficiency;

[0007] 3. When fixing the steel beam, it is impossible to limit the steel beams with different installation holes. The equipment has poor applicability and is prone to shaking. The strength of the limit rod cannot be guaranteed, which affects the fixing effect.

[0020] Further in the present invention; a method for realizing a stable connection structure of an assembled building node comprises the following steps:

[0021] Step 1: Select a suitable connection seat for installation, and plug the mounting holes inside the connection seat into the corresponding positioning blocks on the surface of the fixed support plate, so that the connection seat is initially installed on the upper end of the fixed support plate, and then rotate the installation screw to drive the movable plate to move down along the guide rod, so that the positioning block at the bottom of the movable plate is also inserted into the mounting hole inside the connection seat to clamp and fix the connection seat, thereby ensuring the convenience and stability of the installation of the connection seat; then adjust the internal width of the connection seat according to the specifications of the steel beam to be installed, rotate the rotating block to drive the bidirectional screw to rotate, so that the two sets of movable sliders are close to each other, and the clamping plates move and approach at the same time, ensuring that after the steel beam is installed, the two sets of clamping plates abut against the surface of the steel beam to limit it, thereby improving the stability of the steel beam installation and ensuring the applicability of the equipment;

[0022] Step 2: Turn the drive screw to drive the mounting plate to adjust the use height of the connecting seat. Before using the drive screw, press the movable block to compress the reset spring. At the same time, the movable block is retracted into the interior of the fixed column and no longer supports the sliding plate. Then move the sliding plate downward to disengage the limit card from the interior of the positioning socket. At this time, the limit card no longer limits the handwheel body. The handwheel body can be rotated to drive the drive screw for normal use. After determining the use position of the connecting seat, the limit card can be re-inserted into the positioning socket to ensure that the handwheel body no longer rotates, thereby improving the stability of the handwheel body and ensuring the positioning quality.

At this time, the limit hook is clamped at the bottom end of the lower splicing seat to ensure that it is stably spliced ​​with the upper splicing seat, and then the clamping block is rotated along the damping shaft to lower it and insert it into the inside of the positioning slot to abut the pulling plate to prevent the pulling plate from loosening, thereby ensuring the firmness of the pulling plate and improving the fixing strength of the two sets of mounting seats;

[0024] Step 4: Select a suitable steel beam and pass it through between the two sets of clamping plates and insert it into the inside of the connecting seat. Then, insert the installation column through the steel beam inside the connecting seat, and then insert the positioning bolt from the bottom of the installation column for installation. The positioning bolt abuts against the two sides of the triangular block to push it out. At the same time, the fixed block squeezes the positioning spring to compress it, and then the abutment block abuts against the installation hole inside the steel beam to fix it, ensuring the stability of the steel beam installation. After the positioning bolt is stably installed, rotate the fastening nut along the installation column to install it, so that the positioning bolt and the fastening nut clamp the connecting seat, while ensuring the firmness of the steel beam installation and improving the quality of equipment use.

10. A method for realizing a prefabricated building node stable connection structure according to any one of claims 1 to 9, characterized in that: The steps include: Step 1: Select a suitable connection seat for installation, and plug the mounting holes inside the connection seat into the corresponding positioning blocks on the surface of the fixed support plate, so that the connection seat is initially installed on the upper end of the fixed support plate, and then rotate the installation screw to drive the movable plate to move down along the guide rod, so that the positioning block at the bottom of the movable plate is also inserted into the mounting hole inside the connection seat to clamp and fix the connection seat, thereby ensuring the convenience and stability of the installation of the connection seat; then adjust the internal width of the connection seat according to the specifications of the steel beam to be installed, rotate the rotating block to drive the bidirectional screw to rotate, so that the two sets of movable sliders are close to each other, and the clamping plates move and approach at the same time, ensuring that after the steel beam is installed, the two sets of clamping plates abut against the surface of the steel beam to limit it, thereby improving the stability of the steel beam installation and ensuring the applicability of the equipment; Step 2: Turn the drive screw to drive the mounting plate to adjust the use height of the connecting seat. Before using the drive screw, press the movable block to compress the reset spring. At the same time, the movable block is retracted into the interior of the fixed column and no longer supports the sliding plate. Then move the sliding plate downward to disengage the limit card from the interior of the positioning socket. At this time, the limit card no longer limits the handwheel body. The handwheel body can be rotated to drive the drive screw for normal use. After determining the use position of the connecting seat, the limit card can be re-inserted into the positioning socket to ensure that the handwheel body no longer rotates, thereby improving the stability of the handwheel body and ensuring the positioning quality. Step 3: When multiple sets of mounting seats need to be spliced ​​together for use, the lower splicing seat on one side of the mounting seat is butted against the bottom end of the upper splicing seat, and then the clamping block is rotated along the damping shaft to pull it up, and then the two sets of pulling plates are simultaneously slid along the guide column to compress the limit spring, align the upper splicing seat with the lower splicing seat, and release the pulling plate to reset the limit spring. At this time, the limit hook is clamped at the bottom end of the lower splicing seat to ensure that it is stably spliced ​​with the upper splicing seat, and then the clamping block is rotated along the damping shaft to lower it and insert it into the inside of the positioning slot to abut the pulling plate to prevent the pulling plate from loosening, thereby ensuring the firmness of the pulling plate and improving the fixing strength of the two sets of mounting seats; Step 4: Select a suitable steel beam and pass it through between the two sets of clamping plates and insert it into the inside of the connecting seat. Then, insert the installation column through the steel beam inside the connecting seat, and then insert the positioning bolt from the bottom of the installation column for installation. The positioning bolt abuts against the two sides of the triangular block to push it out. At the same time, the fixed block squeezes the positioning spring to compress it, and then the abutment block abuts against the installation hole inside the steel beam to fix it, ensuring the stability of the steel beam installation. After the positioning bolt is stably installed, rotate the fastening nut along the installation column to install it, so that the positioning bolt and the fastening nut clamp the connecting seat, while ensuring the firmness of the steel beam installation and improving the quality of equipment use.
