[0018] 1. For this steel structure grid installation and fixing structure, by providing a rotatable base, when the cross arm is hoisted to the top of the column and lowered, through the rotatable flipping body, the opening of the clamping channel is increased, thereby facilitating the accurate placement of the cross arm into the clamping channel. When the cross arm completely falls into the clamping channel, under the action of the gravity of the cross arm, the cross arm causes the horizontal part of the flipping body to flip to abut against the bottom surface of the cross arm. Then, the base and the flipping body jointly clamp the cross arm in the clamping channel, and the cross arm, the base, and the flipping body are locked by bolts and nuts, which has the characteristic of being easy to assemble.

[0027] An installation and fixing structure of a steel structure grid, as Figure 1 and Figure 2 shown, includes:

[0028] Column 10 and crossbeam 11 arranged on the top of column 10;

[0029] As Figure 3 , Figure 4 and Figure 5As shown in the figure, the connection component is arranged between the cross arm 11 and the column 10 for connection and locking. The connection component includes a base 20, a flipping body 21 and a clamping channel 22. The flipping body 21 is rotatably connected to the base 20, and the base 20 is rotatably connected to the column 10. The base 20 and the flipping body 21 jointly form the clamping channel 22. The cross arm 11 can be inserted into the clamping channel 22 and locked by bolts. Both the base 20 and the flipping body 21 are plates with an L-shaped cross section. The flipping body 21 is located on the top of the base 20, and the top surfaces of the flipping body 21 and the base 20 are flush. The clamping channel 22 forms a channel with a Y-shaped cross section. The clamping channel 22 includes an upper part and a lower part. The upper half of the clamping channel 22 is funnel-shaped, and the lower half of the clamping channel 22 is rectangular. In this solution, by setting the rotatable base 20, when the cross arm 11 is hoisted to the top of the column 10 and descends, through the flippable flipping body 21, the opening of the clamping channel 22 is increased, which is convenient for accurately placing the cross arm 11 into the clamping channel 22. When the cross arm 11 completely falls into the clamping channel 22, under the action of the gravity of the cross arm 11, the cross arm 11 causes the horizontal part of the flipping body 21 to flip to abut against the bottom surface of the cross arm 11. Then, the base 20 and the flipping body 21 jointly clamp the cross arm 11 in the clamping channel 22, and the cross arm 11, the base 20 and the flipping body 21 can be locked by bolts and nuts. It has the characteristic of being convenient for assembly. Cooperating with the rotatable base 20, the positions of the base 20 and the flipping body 21 can be adjusted to adapt to the installation angle of the cross arm 11. At the same time, when the cross arm 11 descends, it is convenient to adjust the base 20 and the flipping body 21 to ensure that the clamping channel 22 is parallel to the cross arm 11.

[0030] As Figure 4 shown, the connection component further includes a rotating shaft 24. The rotating shaft 24 is fixedly connected to the bottom of the base 20, and the rotating shaft 24 is rotatably connected to the column 10. A shaft hole is provided at the top of the column 10. The rotating shaft 24 is inserted into the shaft hole and rotatably connected to the column 10. An annular anti-detachment groove is provided on the circumferential surface of the rotating shaft 24. A rivet is provided on the side wall of the column 10, and the end of the rivet extends into the anti-detachment groove. As a supplement to the above solution, by setting the rotating shaft 24 and inserting the rivet into the anti-detachment groove, the detachment of the base 20 from the column 10 is restricted, and at the same time, it can ensure that the base 20 can rotate on the top of the column 10, which is convenient for the installation and layout of the cross arm 11.

[0031] As Figure 4As shown in the figure, the side wall of the base 20 is provided with an integrally formed ear plate 23. The flipping body 21 is rotationally connected to the ear plate 23. On the side wall surface of the ear plate 23 close to the base 20, by providing the ear plate 23, it is fixedly connected to the flipping body 21 by a rotating shaft. The rotating shaft is rotationally connected to the ear plate 23 to realize the flipping movement of the flipping body 21. The design of the connection point between the flipping body 21 and the ear plate 23 on the side close to the flipping body 21 enables the flipping body 21 to flip away from the base 20 under the action of gravity, thereby ensuring that the clamping channel 22 is in an open state. To avoid interference, a certain gap is reserved between the bottom of the flipping body 21 and the base 20 for the flipping movement of the flipping body 21, which will not be elaborated here.

[0032] As Figure 2 shown, the joint assembly is arranged at both ends of the cross arm 11 for connecting the ends of multiple cross arms 11 end to end;

[0033] The joint assembly includes a female head 12 and a male head 13. The female head 12 and the male head 13 are respectively fixed at both ends of the cross arm 11. A sinking groove adapted to the male head 13 is formed on the top surface of the female head 12. The male head 13 can be inserted into the sinking groove. By inserting the male head 13 into the sinking groove at the top of the female head 12, the connection and use of two cross arms 11 can be realized. The female head 12 and the male head 13 can be locked by screws and nuts.

[0034] The working principle of the present utility model: By providing the ear plate 23, it is fixedly connected to the flipping body 21 by a rotating shaft. The rotating shaft is rotationally connected to the ear plate 23 to realize the flipping movement of the flipping body 21. The design of the connection point between the flipping body 21 and the ear plate 23 on the side close to the flipping body 21 enables the flipping body 21 to flip away from the base 20 under the action of gravity, thereby ensuring that the clamping channel 22 is in an open state. The cross arm 11 is accurately placed into the clamping channel 22. When the cross arm 11 completely falls into the clamping channel 22, under the action of the gravity of the cross arm 11, the cross arm 11 causes the horizontal part of the flipping body 21 to flip to abut against the bottom surface of the cross arm 11, and the clamping channel 22 gradually contracts. Thus, the base 20 and the flipping body 21 jointly clamp the cross arm 11 in the clamping channel 22, and the cross arm 11, the base 20 and the flipping body 21 can be locked by bolts and nuts.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present utility model.
