Description

Technical Field

[0001] The utility model relates to a stable supporting system of a terminal building roof grid, and belongs to the technical field of grid installation and construction. Background Art

[0002] When constructing an airport terminal, since the lower part is relatively large, a grid is needed to support the roof structure of the airport terminal. After the roof grid is spliced ​​and installed on the ground, it needs to be lifted to the designed height of the top of the support column.

[0003] The existing method of lifting the roof grid is to use standard sections and jacks, see Chinese patent announcement number CN218715281U, and the disclosed technology is: the middle part of the grid is lifted by the bearing bracket and the first jack; although, after the jack is extended from the top of the bearing bracket to lift the roof grid, the top of the bearing bracket is added with standard sections to increase the lifting height, but since the roof grid is at a high height from the ground, the workers are in a high-altitude operation when adding standard sections on the top of the bearing bracket, which poses a great safety hazard.

[0022] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0023] like Figures 1 to 4 shown.

[0024] The present application discloses a stable support system for a terminal roof grid, comprising:

[0025] The two ends of the floor and roof grid 1 are slidably mounted on the supporting columns 11 , and a bearing bracket 2 composed of standard sections is installed in the middle of the floor and roof grid 1 . The bearing bracket 2 is a plurality of multi-point contact supports for the floor and roof grid 1 .

[0026] A retractable telescopic rod 3 is installed in the middle of the bottom of the load-bearing bracket 2. The telescopic rod 3 is composed of a telescopic hydraulic rod. The bottom of the telescopic rod 3 is installed in the ground 4. The top of the telescopic rod 3 is detachably fixedly connected to the bottom of the load-bearing bracket 2. When the top of the telescopic rod 3 is extended, the load-bearing bracket 2 can be lifted, and then a standard section is installed at the bottom of the load-bearing bracket 2 to increase the height of the load-bearing bracket 2.

[0027] A cable wind rope 5 is installed on the side of the load-bearing bracket 2 which is increased to a height of five meters from the ground 4. There are multiple cable wind ropes 5, and one cable wind rope 5 is added for every five meters height of the load-bearing bracket 2 from the ground 4 or the work surface 41. One end of the cable wind rope 5 is fixedly connected to the load-bearing bracket 2, and the other end of the cable wind rope 5 is fixedly connected to the ground 4; the cable wind rope 5 applies oblique force to the load-bearing bracket 2 to prevent the load-bearing bracket 2 from shaking significantly.

[0028] A variable damping member 6 with variable damping force is installed in the middle of the wind rope 5; the variable damping member 6 includes a shell 61 with a gourd-shaped exterior that can undergo elastic deformation, the shell 61 is made of elastic rubber, the inside of the shell 61 is filled with a filling fluid 62 made of water or emulsion, and valves A63 and B64 are connected and installed at both ends of the shell 61. When the filling fluid 62 is compressed air, valves A63 and B64 are airtight nozzles. The density of the filling fluid 62 in the shell 61 is controlled by valves A63 and B64 to achieve variable damping force adjustment of the variable damping member 6.

[0029] The two ends of the cable wind rope 5 are fixedly connected to the two ends of the filling fluid 62, and a bendable spare steel cable 65 is sealed and penetrated through the interior of the shell 61. The length of the spare steel cable 65 is greater than the telescopic length of the shell 61, and the two ends of the spare steel cable 65 are fixedly connected to the cable wind rope 5. After the shell 61 is damaged, the spare steel cable 65 serves as a spare connection between the two ends of the cable wind rope 5.

[0030] The present application provides a method for supporting and constructing a terminal roof grid, comprising the following steps:

[0031] Step 1, splicing of floor and roof grids: assemble the floor and roof grids 1 on the ground 4. The floor and roof grids 1 can slide on the support columns 11. The bearing bracket 2 is installed at the bottom of the floor and roof grids 1. The telescopic rod 3 is installed in the middle of the bottom of the bearing bracket 2. The top of the telescopic rod 3 is detachably fixedly connected to the bottom of the bearing bracket 2, and the bottom of the telescopic rod 3 is installed in the ground 4.

[0032] Step 2, increase the height of the bearing bracket: the telescopic rod 3 extends from the bottom of the bearing bracket 2, so that the bearing bracket 2 is lifted, and a standard section is installed at the bottom of the bearing bracket 2 to increase the height. After the installation is completed, the telescopic rod 3 retracts, and the bottom of the bearing bracket 2 contacts the ground. The top of the telescopic rod 3 is detached from the original connection point of the bearing bracket 2 and fixed to the newly added standard section at the bottom of the bearing bracket 2. Repeat step 2. For every five-meter height of the bearing bracket 2 from the ground 4 or the work surface 41, a cable wind rope 5 is added. At this time, a stable support system for the terminal roof grid is formed. After the increased height of the bearing bracket 2 drags the floor roof grid 1 to the designed height, the bottom of the floor roof grid 1 is installed with the support column 11, and then the bearing bracket 2 is removed.

[0033] When removing the supporting bracket 2, perform step 2 in reverse.

[0034] When a wind rope 5 is installed on the side of the load-bearing bracket 2, the telescopic rod 3 is extended from the bottom of the load-bearing bracket 2 to lift up the load-bearing bracket 2 and gradually increase the overall height. The damping of the variable damping member 6 is controlled to become larger, thereby dynamically controlling the shaking displacement of the load-bearing bracket 2. When the load-bearing bracket 2 is gradually increased as a whole, the wind rope 5 gradually increases in length to adapt to it, thereby solving the problem that the height of the roof truss from the ground is high, and the workers are in a high-altitude working situation when adding standard sections on the top of the load-bearing bracket has great safety hazards.
