Description

Technical Field

[0001] The invention relates to a steel structure, in particular to an assembled steel structure grid structure and an assembling method. Background Art

[0003] The invention patent with application number CN201910469644.8 discloses a steel frame component for the middle column of a steel structure house building, including a steel frame column, and the side walls around the steel frame column are welded with U-shaped mounting plates, and two locking plates are welded on the side of the U-shaped mounting plate facing away from the steel frame column, and a frame beam is arranged on one side of the U-shaped mounting plate, and a first bolt is threadedly connected to one side of the locking plate, and the locking plate is fixedly connected to the frame beam through the first bolt, and a positioning column is fixedly connected to the top of the frame beam, and the number of the positioning columns is four, and the upper end of the positioning column is provided with an external thread, and the surface of the adjacent positioning columns is sleeved with a connecting rod, and the surface of the positioning column is connected with a locking sleeve through an external thread. The present invention does not require drilling or slotting on the steel frame column during installation, and is suitable for use with steel frame columns of various sizes, thereby solving the problem that drilling or slotting in the steel frame column will reduce the strength of the steel frame column. However, the above-mentioned steel frame structure cannot adjust the construction angle of the steel frame structure according to actual needs during the process of connecting to form a steel frame network, because when constructing a steel structure building, it is usually necessary to adjust the angle relationship of the top support of the steel structure according to the construction terrain and the construction purpose such as water transmission and sun shading.

The middle of the water-passing rod 22 The middle of the water spraying rod 23 is a water channel 221, the middle of the water spraying rod 23 is a water spraying channel 231, the lower end of the water spraying rod 23 is evenly provided with water spraying holes 232 communicating with the water spraying channel 231, the middle of the connecting plate 24 is provided with a water receiving channel 241, the water receiving channel 241 connects the water channel 221 and the water spraying channel 231, the water channel 221 is provided with a trigger water structure 26 at both sides of the water receiving channel 241, and the water receiving channel 241 is also provided with a trigger water structure 26, and the trigger water structure 26 includes a water contact fixing sleeve 261, a water-touching sliding sleeve 262, a spring receiving plate 263 and a receiving spring 264, the water-touching fixed sleeve 261 is fixedly installed in the water channel 221 at the positions on both sides of the water receiving channel 241, the water receiving channel 241 is also fixedly connected with a water-touching fixed sleeve 261, the water-touching fixed sleeve 261 is slidably connected with the water-touching sliding sleeve 262, the water channel 221 is fixedly connected with a spring receiving plate 263 at the opposite end of the water-touching fixed sleeve 261 corresponding to the water-touching fixed sleeve 261, and the water receiving channel 241 is fixedly connected with the water-touching fixed sleeve 261 at the opposite end of the water channel 221. A spring receiving plate 263 is also fixedly connected to the lower end, and a receiving spring 264 is fixedly connected between the spring receiving plate 263 and the water-contacting sliding sleeve 262. The side surface of the water-contacting sliding sleeve 262 is evenly provided with through grooves in the circumferential direction, and an annular locking groove 2621 is provided on the water-contacting sliding sleeve 262 located in the water receiving channel 241. A stop mechanism 27 for fixing the water-contacting sliding sleeve 262 in the water receiving channel 241 is provided in the connecting plate 24, and the stop mechanism 27 is connected to the trigger water-passing structure 26 in the water channel 221.

[0053] In the process of water flowing into the side support rod 2, the water flow will first enter the connecting sleeve 21, and then the water flow will enter the water channel 221, and then the water flow will impact the trigger water flow structure 26 in the water channel 221, and after passing through the trigger water flow structure 26 in the water channel 221, the water flow will enter the water receiving channel 241 in the connecting plate 24, and after passing through the trigger water flow structure 26 in the water receiving channel 241, the water flow will enter the water spraying center, and finally be sprayed out through the water spraying hole 232. In the process of water flowing through the trigger water flow structure 26, the water flow will impact the water-contacting sliding sleeve 262, and the water-contacting sliding sleeve 262 will slide along the water-contacting fixed sleeve 261, and finally pass through the trigger water flow structure 26 from the side groove of the water-contacting sliding sleeve 262. At the same time, the trigger water flow structure 26 in the docking water channel 241 is constrained by the stop mechanism 27, and the two trigger water flow structures 26 in the water flow are both affected by the impact. Only then will the stop mechanism 27 be driven to release the constraint of the trigger water-passing structure 26 of the docking water channel 241, so that the water flow can pass through the trigger water-passing structure 26 in the water-connecting channel 241. The advantage of this is that the side support rod 2 will spray water only when water is flowing on both sides of the side support rod 2. When it is deployed on a large scale, the water spraying state of the side support rod 2 can be accurately controlled, which is convenient for reducing the burden on users. During use here, because only when water is flowing on both sides of the water-passing rod 22, that is, when the two trigger water-passing structures 26 in the water channel 221 are triggered, the trigger water-passing structure 26 in the water-connecting channel 241 will be opened, thereby causing the water spraying rod 23 to spray water. In this way, when the staff turns off the water spraying, they only need to close the water inlet control mechanism 52 in one direction to intercept the water flow in the water spraying rod 23, so that it is easy to control when turning off the water flow.

[0054] like Figure 10 to Figure 12 As shown, the stop mechanism 27 includes a stop plate 271, a stop rope 272 and a stop spring 273. The connecting plate 24 and the water-contacting fixed sleeve 261 therein are jointly provided with a stop sliding groove 242. The stop sliding groove 242 is slidably connected with a stop plate 271. The stop plate 271 is clamped in the locking groove 2621. A stop spring 273 is fixedly connected between the stop plate 271 and the bottom surface of the stop sliding groove 242. A stop rope 272 is fixedly connected to the stop plate 271, and the stop rope 272 is fixedly connected to the water-contacting sliding sleeve 262.

[0055] When the water flow impacts the trigger water flow structure 26 on the left and right sides of the water channel 221, the water-contacting sliding sleeve 262 will pull the stop rope 272 during the sliding process, and the stop rope 272 will pull the stop plate 271, so that the stop plate 271 and the locking groove 2621 are separated from each other, thereby releasing the lock of the trigger water flow structure 26 in the water channel 241.

[0056] like Figure 2 and Figure 4 As shown, the direction adjustment mechanism 25 includes a direction fixing block 251, a direction rotating block 252, a locking plate 253 and a locking spring 254. The direction fixing block 251 is fixedly connected to the connecting sleeve 21, and the direction rotating block 252 is fixedly connected to the water passing rod 22. A locking sliding groove 2521 is provided on the direction rotating block 252, and a locking plate 253 is slidably connected in the locking sliding groove 2521. A locking spring 254 is provided in the locking sliding groove 2521, and the two ends of the locking spring 254 are respectively fixedly connected to the locking plate 253 and the bottom surface of the locking sliding groove 2521. The direction fixing block 251 is provided with locking holes 2511 evenly arranged in the circumferential direction, and a plurality of locking rods 2531 corresponding to the locking holes 2511 are fixedly connected to the locking plate 253, and the lower end of the locking plate 253 is fixedly connected to an adjusting hollow rod 2532 that slides through the direction rotation.

[0057] In order to enable the side support plate to change the direction of the spray, thereby expanding the range of the water spray, the rod is inserted into the adjusting hollow rod 2532 on the left and right sides of the water channel 221, and the locking rod 2531 on the locking plate 253 is disengaged from the locking groove 2621 on the direction fixing block 251, and then the locking plate 253 is rotated, and the locking plate 253 drives the direction rotating block 252 and the side support rod 2 to rotate. When the side support rod 2 is rotated to a specific angle, under the action of the locking spring 254, the locking rod 2531 will be reinserted into the locking groove 2621, thereby achieving the purpose of changing the angle of the side support rod 2.

[0058] like Figure 2 As shown, the locking mechanism 3 includes a locking slider 31 and a locking screw 32. A locking groove 15 is provided on the node ball joint 1 corresponding to the arc surface sliding block 12. The locking slider 31 is slidably connected in the locking groove 15. The arc surface sliding block 12 is rotatably connected with a locking screw 32. The locking screw 32 is threadedly connected to the locking slider 31.

[0059] It should be noted that, by rotating the locking screw 32 , the locking slider 31 is locked on the locking groove 15 , thereby achieving the purpose of fixing the arc-surface sliding block 12 .

[0060] The present invention also provides a corresponding assembling method, comprising the following steps:

[0061] S1: Connect each side support rod 2 through the first connection fulcrum 121 on the arc surface sliding block 12 on the node ball joint 1, and control the number and connection position of the node ball joint 1 and the side support rod 2 according to actual needs, so as to form a steel structure network according to actual needs;

[0062] S2: Support the node ball joint 1 through the intermediate support rod 4;
