[0019] The present invention is described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0020] See also Figure 4-8 ,

[0021] A building steel structure includes a horizontal column 101 and two movable tubes 102. The horizontal column 101 has two arc grooves. The two movable tubes 102 are rotatably connected to a rotating shaft through a bearing. A coil spring is installed between the rotating shaft and the inner wall of the movable tube 102. A waterproof cloth 103 is fixedly connected to the rotating shaft. The other end of the waterproof cloth 103 is fixedly connected to the horizontal column 101. Two hollow plates 201 are welded to the lower end of the movable tube 102. Through grooves 202 are formed in the two hollow plates 201. The lower end of the horizontal column 101 is fixedly connected to two hanging platforms 207 by bolts. The lower end of the horizontal column 101 is provided with a lifting mechanism.

[0022] When using the building steel structure, the horizontal column 101 is raised to a suitable position through a lifting mechanism, and then the two movable tubes 102 are pulled. When the movable tubes 102 move, the waterproof cloth 103 is stretched by force, and then the rotating shaft rotates, and the coil spring is curled by force. When the two movable tubes 102 move to the suitable position, the position of the two hollow plates 201 can be fixed, so that the construction of a simple shed can be realized.

[0023] The user can pull the two mobile tubes 102 to different distances according to the actual size of the site, thereby changing the area occupied by the simple shed, making the simple shed more adaptable. The user can also adjust the height of the horizontal column 101 according to his or her own preferences, thereby changing the height of the roof, and can make the two waterproof cloths 103 tilt, which has a good windproof and rain-guiding effect. Compared with the common method of building a simple shed, it is simple and quick.

[0024] When the simple shed needs to be folded up, the user unfixes the two hollow panels 201 and then slowly loosens the two movable tubes 102, so that the two waterproof cloths 103 are automatically rolled up in the two movable tubes 102 under the action of the coil springs. The looseness can reduce the occupied space and avoid damage to the waterproof cloths 103 during daily storage, thus playing a good protective role. Finally, multiple hollow panels 201 are hung on two hanging platforms 207 through the through grooves 202, and the two movable tubes 102 are respectively embedded in the two arc grooves of the cross column 101 to realize the function of fixing the two movable tubes 102, thereby further reducing the occupied space and making it more convenient and stable to carry.

[0025] See also Figure 8 ,

[0026] The lower end of each hollow plate 201 is slidably connected to a telescopic plate 201 , and a plurality of positioning holes 204 are provided on the telescopic plate 201 . The telescopic plate 201 can be fixed in the hollow plate 201 by positioning pins.

[0027] In order to further increase the height of the roof, the telescopic plate 201 is stretched outward in the hollow plate 201 so that the height of the hollow plate 201 is further increased, thereby achieving the function of increasing the height of the roof, and finally the telescopic plate 201 is fixed in the hollow plate 201 by positioning pins.

[0028] See also Figure 5-6 ,

[0029] A steel wire rope 205 is fixedly connected to each hollow slab 201. The steel wire rope is wound around the positioning nails, and then the positioning nails are inserted into the bottom surface, so that the position of the hollow slab 201 can be fixed, thereby playing a wind-resistant role.

[0030] See also Figure 6-7 ,

[0031] The lifting mechanism includes a support frame 401 . The lower end of the horizontal column 101 is fixedly connected to two limit plates 503 by bolts. The two limit plates 503 are both slidably connected in the support frame 401 .

[0032] The support frame 401 supports the horizontal column 101. By controlling the two limit plates 503 to slide inside the support frame 401, the height of the horizontal column 101 can be increased, so that the height of the horizontal column 101 is higher than the height of the two movable tubes 102, and the two waterproof cloths 103 can be tilted, thereby playing a good role in wind resistance and rain diversion.

[0033] See also Figure 6-7 ,

[0034] A screw rod 502 is threadedly connected to the support frame 401 , the upper end of the screw rod 502 is rotatably connected to the horizontal column 101 through a bearing, and the lower end of the screw rod 502 is fixedly connected to the handle 501 through a bolt.

[0035] The two limit plates 503 are slid in the support frame 401 by controlling the screw rod 502 to rotate, thereby realizing the function of manually adjusting the height of the cross column 101 . The handle 501 is convenient for the user to manually operate the screw rod 502 .

[0036] See also Figure 7 ,

[0037] The lower end of the support frame 401 is rotatably connected to a plurality of running wheels 405 via bearings. When the simple shed is in a folded state, the support frame 401 supports other structures. At this time, by pushing the support frame 401, the support frame 401 can be easily moved with the cooperation of the plurality of running wheels 405, thereby facilitating the transportation of the support frame 401.

[0038] See also Figure 6-7 ,

[0039] The left and right ends of the support frame 401 are rotatably connected to the multi-purpose plates 403 through bearings. The lower end of the support frame 401 is fixedly connected to the support plate 404 through bolts. The upper end of the support plate 404 is in contact with the lower ends of the two multi-purpose plates 403.

[0040] By rotating the two multi-purpose boards 403 to a horizontal state, the multi-purpose boards 403 can be used to place items or users can sit on them to rest, and the support boards 404 support the multi-purpose boards 403 to ensure that the multi-purpose boards 403 are in a horizontal state. When the multi-purpose boards 403 are not in use, the two multi-purpose boards 403 are rotated to a vertical state to reduce the occupied space.

[0041] See also Figure 3 ,

[0042] A building steel structure also includes multiple baffles 301, every two baffles 301 are hinged to each other, each baffle 301 is provided with a slider 304, each hollow plate 201 is provided with a slide groove 206, and multiple sliders 304 are slidably connected in the multiple slide grooves 206 respectively.

[0043] The two hinged baffles 301 are installed on the hollow plate 201 through the slider 304 and the slide groove 206, so as to shield the interior of the simple shed and effectively block the wind. When the user adjusts the size of the simple shed according to the floor area, the two baffles 301 can make an adaptive rotation, and the angle changes.

[0044] See also Figure 3 ,

[0045] Each baffle 301 is provided with an opening 302 , and each baffle 301 is connected with a folding plate 303 by circular rotation. A storage cavity 402 is provided in the middle of the support frame 401 .

[0046] When the folding plate 303 is rotated to a horizontal state, the folding plate 303 can be used as a dining table, and it also serves the purpose of ventilation and sunlight intake. When the folding plate 303 is not in use, the folding plate 303 can be rotated to a vertical state. The folding plate 303 can block the opening 302 on the baffle 301, thereby reducing the occupied space and providing wind resistance. The user can choose according to actual needs. When the simple shed needs to be folded, the two baffles 301 can be rotated and folded, and then placed in the storage cavity 402 to further reduce the occupied space.
