Technical Field

[0001] This invention relates to the field of steel structure installation technology, and more specifically, to a steel structure installation and fixing device. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns and other components. The steel beams and steel columns are usually connected by bolt assemblies.

[0003] In the current technology, the common steel structure installation process uses bolts to connect steel beams and steel columns. The number of bolts used at the same connection point is large, which increases the installation time between steel beams and steel columns and reduces the installation efficiency.

The two movable components are connected by a spring. A limiting block is provided at the center of the side of the movable component away from the spring. The limiting block extends through the fixed block into the fixing groove on the side of the side mounting column.

[0010] Preferably, the bottom center of the connecting seat is provided with a mounting groove that communicates with the side mounting cavity. The mounting groove is provided with a bottom mounting plate. The bottom mounting plate is connected and fixed to the bottom of the connecting seat by a fixing bolt. The top center of the bottom mounting plate is provided with a sealing plate that cooperates with the mounting groove. The top of the sealing plate is provided with a plurality of limiting posts. The limiting posts pass through the mounting groove into the side mounting cavity to fix the two ends of the rotating disk.

[0011] Preferably, the moving parts are U-shaped structures, and each of the two moving parts is provided with a spring mounting seat that cooperates with the spring. The two connecting rods are respectively movably connected to the top and bottom of the two ends of the rotating disk, and the other end of the connecting rod is movably connected to the inside of the moving parts through a shaft.

[0012] Preferably, the front and rear side connecting assembly includes an inner cavity extending from the inside of the connecting seat into the protrusion. The top of the inner cavity has several plate mounting slots that mate with the side mounting plate. A starter motor and a fixing component are respectively provided at the center of the bottom and the center of the top of the inner cavity, and a fixing bracket is fixed on the fixing component.

[0013] Preferably, the top output end of the starter motor is provided with a motor shaft, the top end of which is movably connected to the bottom center of the fixing member. The outer surface of the motor shaft is provided with an external thread, and a movable frame is fitted on the external thread. Movable plate two and movable plate one are movably connected to the movable frame and the fixing frame, respectively. Movable plate two and movable plate one are movably connected by a shaft. The other end of movable plate two and movable plate one is movably connected to a push plate. A number of fixed posts are provided at equal intervals on the outer surface of the push plate.

[0014] Preferably, the side mounting plate extends into the inner cavity through the plate mounting groove, the push plate is pressed together with the side mounting plate, the fixing column extends into the fixing groove, the outer surface of the protrusion is symmetrically provided with two inlets and outlets communicating with the inner cavity, the inlets and outlets are inserted with limit kits, the two limit kits are snapped onto the outer surface of the motor shaft to fill the space between the starter motor and the moving frame, the outer surface of the protrusion is provided with a fixing bolt, the other end of the fixing bolt extends into the inlet and outlet to fix the limit kit.

[0015] The beneficial effects of this invention are as follows:

[0016] By designing the connection mechanism, a larger number of bolts can be used at the same connection point when connecting steel beams and steel columns, which increases the installation time between steel beams and steel columns and reduces the installation efficiency of steel beams and steel columns, thus improving the connection efficiency between steel beams and steel columns.

[0017] The design of the left and right side connecting components allows the rotary motor to be started. The rotary motor drives the rotary disk to rotate through the first rotary shaft. The two ends of the rotary disk push two moving parts to the sides through two connecting rods. The moving parts drive the side limiting blocks to pass through the side mounting cavity and engage in the first fixing groove, thus fixing the side mounting column. Then, the bottom mounting plate and sealing plate are inserted into the mounting groove at the bottom of the connecting seat. The limiting column is inserted into the side mounting cavity to limit the rotated rotary disk, thereby helping the rotary disk to bear the pressure and preventing the pressure of the steel beam from being applied to the first rotary shaft, causing damage to the first rotary shaft, thus improving the safety and stability of the steel beam.

[0018] The design of the front and rear side connecting components allows the starter motor to be activated. The starter motor drives the motor shaft, which in turn causes the moving frame to rise. As the moving frame rises, the distance between the moving frame and the fixed frame decreases. As the distance between the moving frame and the fixed frame decreases, the first and second movable plates rotate and gradually unfold. The other ends of the first and second movable plates drive the push plate to move towards the side of the inner cavity. The push plate drives several fixed posts to engage with the second fixed groove on the side of the side mounting plate. Then, two limiting kits are inserted into the inner cavity through the inlet and outlet on the side of the protrusion. The limiting kits are engaged between the raised moving frame and the starter motor. Finally, the protrusion and the limiting kits are fixed together by the fixing bolts on the outer surface of the protrusion.

[0019] The design of the spring and spring mounting base allows for the power to move and reset the moving parts when the side mounting post does not need to be clamped. Attached Figure Description

[0034] Then, the rotary motor 13 is started. The rotary motor 13 drives the rotary disk 15 to rotate through the rotary shaft 14. The two ends of the rotary disk 15 push the two moving parts 17 to move to both sides through the two connecting rods 16.

Then, the bottom mounting plate 33 and the sealing plate 34 are inserted into the mounting groove at the bottom of the connecting seat 2. The limiting column 35 is inserted into the side mounting cavity 10 to limit the rotated rotary disk 15, thereby helping the rotary disk 15 to bear the pressure and preventing the pressure of the steel beam 1 from being applied to the rotary shaft 14, causing damage to the rotary shaft 14, and improving the safety and stability of the steel beam 1.

[0035] Then, start motor 21. Start motor 21 drives motor shaft 23 to rotate. The rotation of motor shaft 23 drives the moving frame 25 to rise. As the moving frame 25 rises, the distance between the moving frame 25 and the fixed frame 26 decreases.
