Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a steel structure frame fixing device. Background Art

[0002] In steel structures, steel columns and steel beams are generally fixed with high-strength bolts. However, the installation height of steel beams is relatively high, so workers need to fix and install the steel beams at a relatively high position. The steel beams need to be lifted to the installation height by mechanical equipment such as cranes or tower cranes. During the installation process, the steel beams will swing left and right in the air, making it difficult for workers to operate and posing certain risks. In addition, when fixing with bolts in the air, the connecting parts need to be fixed at the screw holes and then fixed with multiple bolts, which makes the operation cumbersome and difficult.

A first return spring 69 is fixedly connected to the inner side of the wedge block 63, and the side of the first return spring 69 away from the wedge block 63 is fixedly connected to the fixed plate 6. A button 64 is slidably connected in the second slot 67, and the button 64 is fixedly connected to the second connecting rod 610, and the end of the second connecting rod 610 away from the button 64 is fixedly connected to the second protrusion 611, and the second groove 622 is provided with an inclined surface acting on the second protrusion 611.

[0025] The steel beam 2 is moved to the top of the column 1 by a lifting device such as a crane or a tower crane, and a worker pushes the steel beam 2 onto the U-shaped support frame 3 to align it. The steel beam 2 slowly falls into the U-shaped support frame 3, which avoids the steel beam 2 shaking in the air and causing safety problems to the workers. The U-shaped support frame 3 supports and fixes the steel beam 2. The button 64 at the bottom of the fixing plate 6 connected to the end of the steel beam 2 contacts the U-shaped support frame 3, and the fixing plate 6 falls into the U-shaped support frame 3. The internal structure of the fixing plate 6 is connected to the structure on the U-shaped support frame 3, so that the steel beam 2 and the column 1 are fixed as a whole, thereby improving the stability of the entire steel structure skeleton. The button 64 is in the second slot 6 under the action of the gravity of the fixing plate 6 itself and the support of the U-shaped support frame 3. 7 slides upward, driving the second connecting rod 610 to move upward, forcing the second protrusion 611 to move upward along the inclined surface of the second groove 622. The function of the button 64 and the second protrusion 611 on the second connecting rod 610 is to make the limit bar 62 squeeze the third reset spring 613 to move sideways, and at the same time make the first protrusion 681 stuck in the slot 614 come out, and the wedge block 63 pops out from the first slot 66 with the rebound of the first reset spring and its own gravity, and squeezes the gap between the L-shaped block 5 in the U-shaped support frame 3 through the tip of the wedge block 63, so that the L-shaped block 5 moves along the slide groove 4 and is stuck in the T-shaped groove 61 of the U-shaped support frame 3, thereby completing the fixation of the column 1 and the steel beam 2. The operation is simple and the installation efficiency is improved.

[0026] Furthermore, a support plate 7 is provided on the side of the column 1, and the support plate 7 is located at the bottom of the U-shaped support frame 3. When the steel beam 2 is subjected to downward pressure, it can be transmitted to the support plate 7 through the U-shaped support frame 3, and then to the column 1, thereby ensuring a stable connection between the beam and the column.

[0027] Furthermore, positioning grooves 8 are provided on both sides of the U-shaped support frame 3, and positioning blocks 9 corresponding to the positioning grooves 8 are provided on both sides of the steel beam 2. When the steel beam 2 is aligned with the U-shaped support frame 3, the positioning blocks 9 are aligned with the positioning grooves 8 on the sides of the U-shaped support frame 3, which plays a role in positioning the steel beam 2. The operation is convenient and simple, and the installation efficiency of the workers is improved.

[0028] Furthermore, the end of the wedge block 63 is triangular. After the wedge block 63 is ejected, the tip of the end is more easily squeezed into the middle of the two L-shaped blocks 5, and the inclined surface of the end of the wedge block 63 can squeeze the two L-shaped blocks 5 to both sides and snap into the T-shaped groove 61, thereby completing the fixation of the column 1 and the steel beam 2.

[0029] Example 2

[0030] Reference Figure 1-6The difference between this embodiment and the first embodiment is that a pull ring 10 is provided on the side of the column 1, the pull ring 10 is located above the steel beam 2, and a lifting ring 11 is provided on the top surface of the fixing plate 6, and the lifting ring 11 is connected to the pull ring 10 by a steel cable. After the steel beam 2 is fixed on the U-shaped support frame 3, the pull ring 10 is welded on the side of the column 1 above the fixing plate 6, and the lifting ring 11 is connected to the pull ring 10 by a steel cable. When the steel cable is in a taut state, it shares the weight of the steel beam 2 and strengthens the connection between the steel beam 2 and the column 1.

[0031] Furthermore, it also includes a U-shaped clamping plate 12 and a clamping bolt 13. A threaded through hole 14 is opened on one side wall of the U-shaped clamping plate 12. The clamping bolt 13 is arranged in the threaded through hole 14. The end of the clamping bolt 13 is rotatably connected to a clamping plate 15. One side of the U-shaped clamping plate 12 is closely attached to the side of the fixing plate 6, and the other side is closely attached to the side of the flange of the column 1. Move both sides of the U-shaped clamping plate 12 to the side of the fixing plate 6 and the side of the flange of the column 1, rotate the clamping bolt 13, and drive the clamping plate 15 to approach the side of the fixing plate 6 until the U-shaped clamping plate 12 clamps the fixing plate 6 and the column 1, thereby improving the connection between the beam and the column.

[0032] The use process of the utility model is as follows: when using the utility model, the steel beam 2 is lifted and moved to the installation position by a lifting device such as a crane or a tower crane, the steel beam 2 is aligned with the U-shaped support frame 3 and slowly dropped into the U-shaped support frame 3, and the U-shaped support frame 3 plays a role of supporting and fixing the steel beam 2, and at the same time prevents workers from being unable to install safely due to the shaking of the steel beam 2. The side positioning block 9 of the steel beam 2 is aligned with the positioning groove 8 and is inserted into the U-shaped support frame 3 to play a positioning role, thereby improving the installation efficiency. The button 64 at the bottom of the steel beam 2 contacts the U-shaped support frame 3, driving the second connecting rod 610 to move upward, forcing the second protrusion 611 to move upward along the inclined surface of the second groove 622, and at the same time, the limit strip 62 squeezes the third reset spring 613 to move sideways until the first connecting rod 65 is stuck in the slot 614 0 comes out, the wedge block 63 pops out from the first slot 66, squeezing the gap between the L-shaped card blocks 5 in the U-shaped support frame 3, so that the L-shaped card block 5 moves and is stuck in the T-shaped groove 61 of the U-shaped support frame 3, completing the fixation of the column 1 and the steel beam 2. The operation is simple and the installation efficiency is improved. The pull ring 10 on the column 1 is connected to the lifting ring 11 on the fixing plate 6 through the steel cable. When the steel cable is in a taut state, the weight of the steel beam 2 is shared and the connection between the steel beam 2 and the column 1 is strengthened. The two sides of the U-shaped clamping plate 12 are moved to the side of the fixing plate 6 and the side of the flange of the column 1, and the tightening bolt 13 is rotated to drive the pressing plate 15 to approach the side of the fixing plate 6 until the U-shaped clamping plate 12 clamps the fixing plate 6 and the column 1, thereby improving the connection between the beam and the column. The whole operation is simple and the installation efficiency is improved.
