Description

Technical Field

[0001] This application relates to the technical field of steel structure connections, and particularly to a rapid assembly steel structure building connection device. Background Art

[0002] A steel structure workshop is a building form in which the main load-bearing members are made of steel. Its main support members are the T-shaped steel structures composed of steel columns and steel beams. When constructing a steel structure workshop, a crane is required to hoist the T-shaped steel structure. However, during the hoisting movement and due to external wind factors, a large inertial force will be generated on the columns. To maintain the stability of the columns, counterweights need to be set to balance these forces. The setting of counterweights can adjust the center of gravity of the structure, making the pressure on the columns more uniform;

[0003] However, the existing counterweight structures are often additional equipment and need to be removed after use. After the counterweight structure is removed, metal connecting rods need to be installed between multiple T-shaped steel structures, which will undoubtedly cause a large amount of time waste during the installation and construction of steel structure buildings, resulting in low efficiency. Moreover, since the metal rods are installed at a position slightly above the middle of the T-shaped steel structure, a crane is also required for hoisting during installation. The existing hoisting process lacks an auxiliary fixing component, resulting in a series of uncertain factors during the hoisting process. Slight ones such as deviation from the predetermined position, causing slow installation, and serious ones such as unstable hoisting and part detachment, posing safety hazards, etc. Therefore, a connection device that can quickly assemble the support base of the metal rod is needed to reduce the uncertain factors generated by the inability to fix in time during hoisting.

[0048] When the movable component 5 is adjusted to the base 1, the movable component 5 at the bottom end of the column 21 and the base 1 can jointly act as a weight block, minimizing the yaw phenomenon generated during hoisting and moving;

[0050] Lift the metal strip 64 to the top of the top plate 52. After placing the U-shaped block 62 in position, then pass the fifth bolt 63 through the metal strip 64 and screw it into the vertical plate 61 for fixation, which can complete the horizontal fixation between multiple T-shaped steel structures and prevent them from shifting;

[0051] The guide assembly 7 includes four triangular blocks 71, which are fixedly mounted on the outer edge of the trapezoidal block 51.

The telescopic ends of the two telescopic rods 73 are movably hinged with long plates 74. The middle of the long plate 74 is fixedly connected to the fixing ring 81. The two telescopic rods 73 can be quickly removed from the triangular blocks 71.

[0052] When the fourth bolt 55 is screwed in, the two telescopic rods 73 will rotate and shrink, driving the long plate 74 to approach the movable assembly 5, thereby completing a pre-tightening effect on the fourth bolt 55. When the pre-tightening is completed, the two telescopic rods 73 are quickly removed from the outside of the triangular block 71, and the fourth bolt 55 is completely locked by a tool, so that the movable assembly 5 is completely fixed to the outer edge of the column 21;

[0053] The auxiliary component 9 includes a first threaded rod 91, which is fixedly mounted on the bottom of the crossbeam 33. The telescopic end of the first threaded rod 91 is movably hinged with an octagonal slot block 92, and the bottom of the octagonal slot block 92 is clamped with a second threaded rod 93.

[0054] The first threaded rod 91 is screwed into the bottom of the crossbeam 33, and one end of the second threaded rod 93 is clamped in the octagonal groove block 92, and the other end of the second threaded rod 93 is movably sleeved on the edge of the U-shaped rod 72. At this time, the second threaded rod 93 is shortened, and a stable triangular structure is formed between the transverse component 3 and the movable component 5 through the auxiliary component 9, thereby playing an auxiliary fixing role.

[0055] Working principle:

[0056] When using the present invention, first adjust the movable component 5 to the base 1, and then use a tool to rotate the hexagonal block 811 counterclockwise. The hexagonal block 811 will transmit the rotational force to the ratchet 88. When the ratchet 88 rotates, the latching tooth 89 on its top will be pushed upward, and the torsion spring of the torsion rod 810 will be forced to reset, and the multiple protruding teeth of the ratchet 88 will always be engaged. After the fixed ring 81 is continuously rotated counterclockwise, the spring 86 inside the circular dish 83 will be forced to curl up. When the spring 86 exceeds its maximum force, the steel column 87 will be separated from the circular groove 84 originally engaged, and move counterclockwise to the next circular groove 84. At this time, the user will clearly feel the difference in the applied rotational torque and the sound generated by the displacement of the steel column 87. At this time, the rotational force on the hexagonal block 811 is stopped in time, and the spring 86 will store the elastic potential energy of the clockwise rotation, and will not be actively released under the engagement of the ratchet 88 and the latching tooth 89.

[0057] Start the crane to hoist the vertical component 2. During the hoisting process, the base 1 and the movable component 5 located at the bottom end of the column 21 act as counterweights, which can provide good bottom negative gravity for the vertical component 2 and minimize the yaw phenomenon generated during hoisting movement. When the hoisting is completed and the vertical component 2 vertically falls into the prepared pit, pour cement at the position where the base 1 is located. The flowing cement will fill the first square hole 11 and the second square hole 12. After solidification, it can provide stronger fixation for the vertical component 2;

[0058] At this time, lift the movable component 5 to the middle and upper part of the column 21, align the fourth bolt 55 with the reserved hole position of the column 21, release the limiting function of the ratchet tooth 89 on the ratchet wheel 88, and the clockwork spring 86 will release elastic potential energy counterclockwise. The fourth bolt 55 will be driven by the sleeve 82 to thread into the column 21 clockwise. When the fourth bolt 55 threads in, the two telescopic rods 73 will rotate and contract, driving the long plate 74 to approach the movable component 5, and then completing a pre-tightening effect on the fourth bolt 55. When the pre-tightening is completed, quickly remove the two telescopic rods 73 from outside the triangular block 71, and use tools to completely lock the fourth bolt 55 to completely fix the movable component 5 on the outer edge of the column 21;

[0059] After multiple vertical components 2 are installed by repeating the above steps, hoist the metal strip 64 to the top of the top plate 52. After placing and positioning the U-shaped block 62, then pass the fifth bolt 63 through the metal strip 64 and thread it into the vertical plate 61 for fixation;

[0060] After the metal strip 64 is installed, fix the fixing piece 31 and the cross beam 33 on the left and right sides of the rectangular block 22 through multiple first bolts 32, and install the ceiling connection component 4 on the top of the cross beam 33. First, lock the C-shaped block 41 on the top of the cross beam 33 through the second bolt 42, and then lock the pressing block 44 and the return-shaped steel sheet 43 on the right side of the C-shaped block 41 in sequence through the third bolt 45. The shape of the return-shaped steel sheet 43 is a return shape, and the connection part of the outer steel ceiling is nested in the return-shaped steel sheet 43;

[0061] After the above structure is installed, screw the first threaded rod 91 into the bottom of the cross beam 33, and snap one end of the second threaded rod 93 into the octagonal groove block 92. The other end of the second threaded rod 93 is movably sleeved on the edge of the U-shaped rod 72. At this time, shorten the second threaded rod 93, and a stable triangular structure is formed between the transverse component 3 and the movable component 5 through the auxiliary component 9, so as to play an auxiliary fixing role.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
