[0014] Preferably, the crossbeam is fixedly connected with a fixed plate through a cushion block, the spacing plate is fixedly connected to the fixed plate, the spacing plate is fixedly provided with a fixed plate, and the waterproof cloth is connected between the two fixed plates.

[0015] The implementation method of the steel structure roof structure is as follows:

[0016] Step 1, a support is fixedly installed at the top of the stand column, the support is horizontally arranged, crossbeams are symmetrically installed on the two sides of the support, a top plate is installed at the bottom between the two spaced crossbeams, a fixed plate is installed at the top through a cushion block, and a spacing plate is installed through the fixed plate;

[0017] Step 2, install the connecting block on the bracket, the connecting block corresponds to the position of the crossbeam on the top of the top plate, and the top is flush with the fixed plate;

[0018] Step 3, rotate and install the movable plate on both sides of the connecting block, rotate and install the adjusting block on the end of the crossbeam on the top of the top plate away from the connecting block, the bevel edge of the adjusting block is installed with the pressing strip and the spring sheet, and the end of the spring sheet away from the adjusting block is connected with the sliding block two which is slidingly fitted on the crossbeam;

[0019] Step 4, install the mounting block on the end of the crossbeam on the bottom of the movable plate away from the connecting block, and rotate and install the pressing plate on the mounting block, install the first linkage shaft on the pressing plate, rotate and install the second linkage shaft on the free end of the first linkage shaft, and rotate and install the rotating shaft on the free end of the second linkage shaft;

[0020] Step 5, rotate and install the fixed block on the top of the movable plate, install the waterproof cloth on the fixed plate of the spacing plate, install the water baffle on the fixed block, the water baffle is located between the two spacing plates at both ends, and the bottom is pressed on the top surface of the waterproof cloth;

[0021] Step 6, when it rains, rain will directly fall on the waterproof cloth, and a concave area will be formed by the shielding of the waterproof cloth and the spacing plate, so that a water layer will be formed on the surface of the waterproof cloth, and the rainwater accumulated on the basis of the water layer is directly in contact with the water layer instead of directly with the waterproof cloth, and the rainwater will gradually accumulate, the water layer will be thicker and thicker, so that the subsequent rainwater will directly hit the water layer with a certain thickness, which has a buffering effect on the falling rainwater;

[0022] When the rainwater in the concave accumulates to a certain extent, due to the action of gravity, the spring sheet is deformed under the downward pressure of the accumulated rainwater, and the sliding block two will slide along the surface of the crossbeam away from the adjusting block, in the process of moving the sliding block two, the adjusting block will rotate correspondingly, and the end of the movable plate away from the connecting block will tilt downward, and the sliding block one on the lower surface of the movable plate will move in the sliding groove;

[0023] When the movable plate is inclined downward, the water baffle is also moved downward, and the side plate on one side of the fixed block is gradually moved to a position below the upper end of the pressing plate. When the adjusting block is rotated to the position where the inclined edge is close to the horizontal beam, the pressing strip on the inclined edge of the adjusting block is in contact with the second linkage shaft and presses the second linkage shaft downward. The pressing strip moves along an arc-shaped track, so that the second linkage shaft moves from the pressing plate to the direction of the rotating shaft. The second linkage shaft drives the pressing plate to move, so that the upper end of the pressing plate exerts a pressing action on the side plate. Under the pressing action, the side plate drives the water baffle to overturn through the fixed block, so that a gap is formed between the water baffle and the waterproof cloth, and the remaining accumulated rainwater can directly leak out of the gap. After the rainwater is discharged, the spring piece is reset by the elastic force, and the center of gravity of the water baffle during the discharge of the accumulated water is always located on the side of the rotating center close to the connecting block, so that the water baffle can be reset by gravity at the first time after the pouring is completed.

[0024] Compared with the prior art, the present application has the following advantages:

[0025] 1. The waterproof cloth in the present application is elastic and can be stretched. When it rains, the rainwater directly falls on the waterproof cloth. Due to the shielding of the waterproof cloth and the spacing plate, a concave area is formed, and the rainwater can be accumulated in the concave area, so that a water layer is formed on the surface of the waterproof cloth. The rainwater accumulated on the basis of the water layer is in contact with the water layer directly, rather than directly with the waterproof cloth. The rainwater is gradually accumulated, and the water layer is gradually thickened. The subsequent rainwater directly hits the water layer with a certain thickness, which has a buffering effect on the falling rainwater, thereby avoiding the situation that the local rainwater frequently hits the surface of the waterproof cloth, and playing a role in protecting the surface coating of the waterproof cloth.

[0026] 2. When the rainwater accumulated in the concave area reaches a certain degree, the spring piece is deformed due to the downward pressure of the accumulated rainwater under the action of gravity, and the sliding block two slides along the surface of the horizontal beam away from the adjusting block. During the movement of the sliding block two, the adjusting block rotates correspondingly, and the end of the movable plate away from the connecting block is inclined downward. The sliding block one on the lower surface of the movable plate moves in the sliding groove. The inclination of the movable plate affects the shape of the concave, and the rainwater accumulated in the concave directly overflows, thereby realizing the discharge effect of the rainwater.

[0043] In the embodiment of the application, the frame structure of the roof is formed by the combination of the stand 3, the support 4 and the cross beam 8, the stand 3 and the support 4 are connected together by direct welding, one end of each cross beam 8 is detachably clamped on the two sides of the support 4 through bolts, the top plate 9 is fixedly installed between the lower surfaces of the cross beams 8, and the inner and outer surfaces of the top plate 9 are provided with waterproof layers.

[0044] Two cross beams 8 spaced apart by a cross beam 8 are fixedly connected with fixed plates 12 through the cushion blocks 2, the fixed plates 12 are fixedly connected with the spacing plates 5, the tarpaulin 1 is arranged between the two fixed plates 12, the tarpaulin 1 directly contacts with rainwater, the upper and lower two layers of waterproof structures are arranged, the tarpaulin 1 directly bears the rainwater and is used for discharging the accumulated water, and the top plate 9 is arranged inside and serves as a second waterproof structure.

[0045] The movable plate 6 is arranged on the spaced beams 8, and the upper surface of the movable plate 6 is fixedly connected with the waterproof cloth 1. The waterproof cloth 1 is elastic and can be stretched. When it rains, the rainwater directly falls on the waterproof cloth 1. Due to the shielding of the waterproof cloth 1 and the spacing plate 5, a recessed area is formed, and the rainwater can be accumulated in the recessed area, so that a water layer is formed on the surface of the waterproof cloth 1. The rainwater accumulated on the basis of the water layer is in contact with the water layer directly instead of being in contact with the waterproof cloth 1 directly. The rainwater is gradually accumulated, and the water layer is thicker and thicker. The subsequent rainwater directly hits the water layer with a certain thickness, has a buffering effect on the falling rainwater, thereby avoiding the situation that the local rainwater frequently hits the surface of the waterproof cloth 1, and plays a role in protecting the surface coating of the waterproof cloth 1.

[0046] When the rainwater accumulated in the recess reaches a certain degree, due to the gravity, the spring sheet 23 is deformed under the downward pressure of the accumulated rainwater, the sliding block two 24 slides along the surface of the beam 8 away from the adjusting block 25.

[0047] When the movable plate 6 inclines downward, the water baffle 7 also moves downward at the same time. The side plate 13 on one side of the fixed block 14 gradually moves to a position below the upper end of the pressing plate 16. When the adjusting block 25 rotates to the position where the inclined edge is close to the beam 8, the pressing strip 20 on the inclined edge of the adjusting block 25 is in contact with the second linkage shaft 21 and presses the second linkage shaft 21 downward. The pressing strip 20 moves along an arc-shaped track, so that the second linkage shaft 21 moves from the pressing plate 16 to the direction of the rotating shaft 22. The second linkage shaft 21 drives the pressing plate 16 to move, so that the upper end of the pressing plate 16 exerts a pressing force on the side plate 13. Under the pressing force, the side plate 13 drives the water baffle 7 to overturn through the fixed block 14. A gap is formed between the water baffle 7 and the waterproof cloth 1, and the remaining accumulated rainwater directly leaks out of the gap, thereby achieving the effect of discharging the rainwater. After the rainwater is discharged, the elastic force of the spring sheet 23 resets the adjusting block 25 and the movable plate 6.

[0048] The implementation method of the steel structure roof structure is as follows:

[0049] Step 1, a support 4 is fixedly installed at the top of the stand column 3. The support 4 is horizontally arranged, and the beams 8 are symmetrically installed on both sides of the support 4. The top plate 9 is installed at the bottom between the two spaced beams 8, and the fixed plate 12 is installed at the top through the cushion block 2, and the spacing plate 5 is installed through the fixed plate 12.

[0050] Step 2, install the connecting block 11 on the support 4, the connecting block 11 corresponds to the position of the crossbeam 8 on the top of the top plate 9, and the top is flush with the fixed plate 12;

[0051] Step 3, rotate the movable plate 6 on both sides of the connecting block 11, and rotate the adjusting block 25 on the end of the crossbeam away from the connecting block 11 on the top of the top plate 9, the bevel edge of the adjusting block 25 is installed with the pressing strip 20 and the spring piece 23, the end of the spring piece 23 away from the adjusting block 25 is connected with the sliding block two 24, and the sliding block two 24 is slidingly fitted on the crossbeam 8;

[0052] Step 4, install the mounting block 15 on the end of the crossbeam 8 away from the connecting block 11 at the bottom of the movable plate 6, and rotate the pressing plate 16 on the mounting block 15, install the first linkage shaft 17 on the pressing plate 16, rotate the second linkage shaft 21 on the free end of the first linkage shaft 17, and rotate the rotating shaft 22 on the free end of the second linkage shaft 21;

[0053] Step 5, rotate the fixed block 14 on the top of the movable plate 6, install the waterproof cloth 1 on the fixed plate 12 of the spacing plate 5, and install the water baffle 7 on the fixed block 14, the water baffle 7 is located between the two spacing plates 5 at both ends and is pressed on the top surface of the waterproof cloth 1 at the bottom;

[0054] Step 6, when it rains, the rain will directly fall on the waterproof cloth 1, and a concave area will be formed by the shielding of the waterproof cloth 1 and the spacing plate 5, so that a water layer will be formed on the surface of the waterproof cloth 1, and the rainwater accumulated on the water layer is in direct contact with the water layer rather than the waterproof cloth 1, and the rainwater will gradually accumulate, and the water layer will become thicker, so that the subsequent rainwater directly hits the water layer with a certain thickness, which has a buffering effect on the falling rainwater;

[0055] When the rainwater in the concave area accumulates to a certain degree, the spring piece 23 will be deformed due to the downward pressure of the accumulated rainwater, and the sliding block two 24 will slide along the surface of the crossbeam 8 away from the adjusting block 25, in the process of moving, the adjusting block 25 will rotate correspondingly, and the end of the movable plate 6 away from the connecting block 11 will tilt downward, and the sliding block one 18 on the lower surface of the movable plate 6 will move in the sliding groove 19;

[0056] When the movable plate 6 is inclined downward, the water baffle 7 is also moved downward, and the side plate 13 on one side of the fixed block 14 is gradually moved to a position below the upper end of the pressing plate 16. When the adjusting block 25 is rotated to the position where the inclined edge is close to the horizontal beam 8, the pressing strip 20 on the inclined edge of the adjusting block 25 is in contact with the second linkage shaft 21 and presses the second linkage shaft 21 downward. The pressing strip 20 moves along an arc-shaped track, so that the second linkage shaft 21 moves from the pressing plate 16 to the direction of the rotating shaft 22. The second linkage shaft 21 drives the pressing plate 16 to move, so that the upper end of the pressing plate 16 exerts a pressing action on the side plate 13. Under the pressing action, the side plate 13 drives the water baffle 7 to overturn through the fixed block 14. Then, a gap is formed between the water baffle 7 and the waterproof cloth 1, and the remaining accumulated rainwater can directly leak out of the gap. After the rainwater is discharged, the elastic force of the spring piece 23 can reset the adjusting block 25 and the movable plate 6. The center of gravity of the water baffle 7 during the discharge of the accumulated rainwater is always located on the side close to the connecting block 11, so that the water baffle 7 can be reset by gravity at the first time after the pouring is completed.

It should be noted that those skilled in the art can make several improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.

4. A waterproof and drainable steel roof structure according to claim 3, characterized in that, The bracket (4) has multiple mounting slots (10) symmetrically arranged on both sides corresponding to the crossbeam (8). One end of the crossbeam (8) is inserted into the mounting slot (10) and fixed by bolts.

5. A waterproof and drainable steel roof structure according to claim 4, characterized in that, The crossbeam (8) is fixedly connected to a fixing plate (12) via a pad (2), the partition plate (5) is fixedly connected to the fixing plate (12), the partition plate (5) is fixedly provided with the fixing plate (12), and the waterproof cloth (1) is connected between the two fixing plates (12).

6. The method for implementing a waterproof and drainable steel roof structure according to claim 5, characterized in that, The steps are as follows: Step 1: Fix bracket (4) on the top of column (3). The bracket (4) is horizontal. Crossbeams (8) are symmetrically installed on both sides of the bracket (4). Top plate (9) is installed at the bottom between the two crossbeams (8). Fixing plate (12) is installed on the top through pad (2). Spacing plate (5) is installed through fixing plate (12). Step 2: Install the connecting block (11) on the bracket (4). The connecting block (11) corresponds to the position of the crossbeam (8) located at the top of the top plate (9), and the top is flush with the fixing plate (12). Step 3: Rotate and install movable plates (6) on both sides of the connecting block (11), and rotate and install adjusting block (25) on the end of the crossbeam at the top of the top plate (9) away from the connecting block (11). Install pressing strip (20) and spring plate (23) on the inclined side of adjusting block (25). Connect slider two (24) to the end of spring plate (23) away from adjusting block (25). Sliding slider two (24) slides on the crossbeam (8). Step 4: Install mounting block (15) on the end of the crossbeam (8) at the bottom of the movable plate (6) away from the connecting block (11), and rotate and install pressing plate (16) on mounting block (15). Install first linkage shaft (17) on pressing plate (16), rotate and install second linkage shaft (21) at the free end of first linkage shaft (17), and rotate and install rotating shaft (22) at the free end of second linkage shaft (21). Step 5: Rotate and install the fixing block (14) on the top of the movable plate (6), install the waterproof cloth (1) on the fixing plate (12) of the partition plate (5), install the water baffle (7) on the fixing block (14), with the two ends of the water baffle (7) located between the two partition plates (5), and the bottom pressed against the top surface of the waterproof cloth (1); Step 6: When it rains, the rainwater will fall directly onto the waterproof cloth (1). The waterproof cloth (1) and the partition (5) form a recessed area, which will form a water layer on the surface of the waterproof cloth (1). The rainwater that accumulates on the water layer will directly contact the water layer, rather than directly contact the waterproof cloth (1). The rainwater will gradually accumulate and the water layer will become thicker and thicker. Then the subsequent rainwater will directly hit the water layer with a certain thickness, which will have a buffering effect on the rainwater. When the rainwater in the depression accumulates to a certain extent, due to the effect of gravity, the spring sheet (23) is deformed by the downward pressure of the accumulated rainwater. The second slider (24) will slide along the surface of the crossbeam (8) in a direction away from the adjusting block (25). During the movement of the second slider (24), the adjusting block (25) will rotate accordingly. Then the end of the movable plate (6) away from the connecting block (11) will tilt downward. The first slider (18) on the lower surface of the movable plate (6) moves in the groove (19). When the movable plate (6) tilts downward, it will simultaneously drive the baffle plate (7) to move downward. The side plate (13) on one side of the fixed block (14) will gradually move down to the position below the upper end of the pressing plate (16). When the adjusting block (25) rotates to the point where the inclined side is close to the crossbeam (8), the pressing strip (20) on the inclined side of the adjusting block (25) will contact the second linkage shaft (21) and press down on the second linkage shaft (21). The pressing strip (20) moves in an arc trajectory, causing the second linkage shaft (21) to move from the pressing plate (16) toward the rotating shaft (22). The second linkage shaft (21) will pull The pressing plate (16) moves, so that the upper end of the pressing plate (16) will exert a squeezing effect on the side plate (13). Under the squeezing effect, the side plate (13) will drive the water baffle (7) to flip through the fixing block (14). Then a gap will appear between the water baffle (7) and the waterproof cloth (1). The remaining accumulated rainwater will leak directly from the gap. After the rainwater is discharged, the elastic force of the spring plate (23) will cause the adjusting block (25) and the movable plate (6) to reset. When the water baffle (7) is draining the accumulated water, the center of gravity is always located on the side of the rotation center close to the connecting block (11). After the water is poured out, it can be reset by gravity immediately.
