[0012] Preferably, the pressing bar is arranged above the second linkage shaft, a protrusion is arranged at the upper end of the pressing plate, and the first linkage shaft is connected to the protrusion.

[0013] Preferably, a plurality of mounting grooves corresponding to the cross beam are symmetrically arranged on both sides of the bracket, and one end of the cross beam is clamped in the mounting groove and fixed by bolts.

[0014] Preferably, the cross beam is fixedly connected to a fixing plate via a pad, the spacer plate is fixedly connected to the fixing plate, a fixing plate is fixedly arranged on the spacer plate, and the waterproof cloth is connected between the two fixing plates.

[0015] The implementation method of the steel structure roof structure, the steps are as follows:

[0016] Step 1: Fix the bracket on the top of the column. The bracket is set horizontally. The beams are symmetrically installed on both sides of the bracket. The top plate is installed at the bottom between the two spaced beams. The top is installed with a fixing plate through a pad, and the spacer is installed through the fixing plate.

[0017] Step 2: Install the connecting block on the bracket. The connecting block should correspond to the crossbeam at the top of the top plate, and the top should be flush with the fixing plate.

[0018] Step 3, rotate and install the movable plates 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, install the pressing strip and the spring sheet on the bevel of the adjusting block, and the end of the spring sheet away from the adjusting block is connected with the slider 2, and the slider 2 is slidably matched on the crossbeam;

[0019] Step 4, install a mounting block at one end of the crossbeam at the bottom of the movable plate away from the connecting block, and rotatably install a pressing plate on the mounting block, install a first linkage shaft on the pressing plate, rotatably install a second linkage shaft at the free end of the first linkage shaft, and rotatably install a rotating shaft at 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 partition plate, and install the water retaining plate on the fixed block. The two ends of the water retaining plate are located between the two partition plates, and the bottom is pressed on the top surface of the waterproof cloth.

[0021] Step 6: When it rains, rain will directly fall onto the tarpaulin, and a concave area will be formed by the shielding of the tarpaulin and the partition board, thereby forming a water layer on the surface of the tarpaulin. The rainwater accumulated on the basis of the water layer will directly contact the water layer instead of the tarpaulin. 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 that hits down.

[0022] When the rainwater in the depression accumulates to a certain extent, due to the effect of gravity, the spring sheet is deformed by the pressure of the accumulated rainwater, and the slider 2 will slide along the surface of the beam in the direction away from the adjustment block. During the movement of the slider 2, the adjustment block will rotate accordingly, and the end of the movable plate away from the connecting block will tilt downward, and the slider 1 on the lower surface of the movable plate will move in the slide groove;

[0023] When the movable plate tilts downward, it will also drive the water baffle plate to move downward, and the side plate on one side of the fixed block will gradually move down to a position below the upper end of the pressing plate. When the adjusting block rotates until the hypotenuse is close to the crossbeam, the pressing strip on the hypotenuse of the adjusting block will contact the second linkage shaft and press down the second linkage shaft. The pressing strip moves in an arc trajectory, causing the second linkage shaft to move from the pressing plate toward the direction of the rotating shaft, and the second linkage shaft will drive the pressing plate to move, so that the upper end of the pressing plate will cause an extrusion effect on the side plate. Under the extrusion effect, the side plate will drive the water baffle plate to flip over through the fixed block, then a gap will appear between the water baffle plate and the waterproof cloth, and the remaining accumulated rainwater will directly leak out of the gap. After the rainwater is discharged, the elastic force of the spring sheet will reset the adjusting block and the movable plate. The center of gravity of the water baffle plate when discharging accumulated water is always located on the side of the rotation center close to the connecting block, and it can be reset by gravity as soon as possible after the dumping is completed.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The waterproof cloth in the present invention is elastic and can be stretched. When it rains, rainwater will directly fall onto the waterproof cloth. Since the waterproof cloth and the partition plate form a concave area, rainwater can be accumulated in the concave area, thereby forming a water layer on the surface of the waterproof cloth. The rainwater accumulated on the basis of the water layer is in direct contact with the water layer instead of the waterproof cloth. 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 has a buffering effect on the rainwater that falls, thereby avoiding the situation where 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. In the present invention, when the rainwater in the depression accumulates to a certain extent, due to the action of gravity, the spring sheet is deformed by the downward pressure of the accumulated rainwater, and the slider 2 will slide along the surface of the beam in the direction away from the adjusting block. During the movement of the slider 2, the adjusting block will rotate accordingly, and the end of the movable plate away from the connecting block will tilt downward, and the slider 1 on the lower surface of the movable plate will move in the slide groove. The inclination of the movable plate will affect the shape of the depression, and the rainwater accumulated in the depression will directly overflow, thereby achieving the effect of discharging rainwater.

[0037] The adjustment mechanism also includes an adjustment block 25, which is rotatably connected to the beam 8 and is arranged below the movable plate 6. A slider 18 is fixedly connected to the bottom of the movable plate 6. A slide groove 19 is arranged in the adjustment block 25. The slide groove 19 is slidably inserted in the slide groove 19. An elastic mechanism is arranged on one side of the adjustment block 25. The adjustment block 25 is against the surface of the beam 8 through the elastic mechanism. On rainy days, the surface of the waterproof cloth 1 will directly receive more rainwater, and the waterproof cloth 1 and the movable plate 6 will bear the pressure from the rainwater. The movable plate 6 is rotatably connected to the beam 8, and one end is supported by the adjustment block 25. Under the action of the pressure of the rainwater, the movable plate 6 will rotate and tilt. The surface inclination will cause the accumulated rainwater on the surface to flow directly downward, and the rainwater will be discharged in time to avoid serious water accumulation affecting the waterproof effect of the structure.

[0038] The elastic mechanism includes a spring sheet 23, one end of the spring sheet 23 is fixedly connected to the adjusting block 25, and the other end of the spring sheet 23 is fixedly connected to the slider 24. The slider 24 slides on the surface of the beam 8. When the movable plate 6 is subjected to a large pressure, it will be pressed downward, and the pressure will be transmitted to the spring sheet 23 in the elastic mechanism, so that the adjusting block 25 rotates, and the slider 24 slides on the surface of the beam 8, and finally the movable plate 6 can be tilted to achieve the effect of dumping accumulated water.

[0039] The cross-section of the adjusting block 25 is a right-angled triangle structure. The spring sheet 23 is connected to one side of the hypotenuse of the adjusting block 25.

The adjusting block 25 is arranged at an inverted triangle angle. The adjusting block 25 is arranged at an inverted triangle angle, and one corner is rotatably connected to the crossbeam 8, so that the hypotenuse is in a suspended state. When the movable plate 6 is subjected to pressure, the adjusting block 25 rotates, so that the inclined surface gradually contacts the surface of the crossbeam 8, and then the movable plate 6 can be tilted.

[0040] A fixing block 14 is fixedly connected to the back of the water retaining plate 7 , and the fixing block 14 is rotatably connected to the movable plate 6 . A side plate 13 is arranged on one side of the fixing block 14 , and a mounting block 15 is arranged at the end of the cross beam 8 .

[0041] The linkage mechanism includes a pressing plate 16, which is rotatably mounted on the mounting block 15. The two sides of the pressing plate 16 are rotatably connected to the second linkage shaft 21 through the first linkage shaft 17. The two sides of the crossbeam 8 are rotatably mounted with a rotating shaft 22. A torsion spring is provided at the connection between the rotating shaft 22 and the crossbeam 8. The end of the second linkage shaft 21 away from the first linkage shaft 17 is rotatably connected to the upper end of the rotating shaft 22. A pressing strip 20 is fixedly connected to the hypotenuse of the adjusting block 25. When the movable plate 6 tilts downward and the adjusting block 25 rotates to the lowest end, the pressing strip 20 will contact the second linkage shafts 21 on both sides and the second linkage shafts 22 are rotated. The movable shaft 21 is pressed downward, and the second linkage shaft 21 pulls the pressing plate 16 to rotate. When the pressing plate 16 rotates, the side plate 13 is located below the pressing plate 16, and then the pressing plate 16 rotates to press the side plate 13 downward, and then the side plate 13 drives the water retaining plate 7 to flip, so that a gap appears between the water retaining plate 7 and the waterproof cloth 1, and the accumulated rainwater blocked by the water retaining plate 7 will flow out, and the torsion spring plays a role of reset. It should be noted that the center of gravity of the water retaining plate 7 here is always located on the side of the rotation center close to the connecting block 11 when draining the accumulated water, and it can be reset by gravity as soon as possible after the dumping is completed.

[0042] The pressing bar 20 is arranged above the second linkage shaft 21 , a protrusion is arranged at the upper end of the pressing plate 16 , the first linkage shaft 17 is connected to the protrusion, and the pressing bar 20 is arranged above the second linkage shaft 21 , so that the pressing bar 20 can act on the second linkage shaft 21 when pressed down.

[0043] In the embodiment of the above technical solution, the frame structure of the roof is formed by combining columns 3, brackets 4, and beams 8. The columns 3 and the brackets 4 are connected together by direct welding. One end of each beam 8 is detachably connected to the two side surfaces of the bracket 4 by bolts. A top plate 9 is fixedly installed between the lower surfaces of each beam 8, and a waterproof layer is provided on the inner and outer surfaces of the top plate 9.

[0044] Two cross beams 8 separated by a cross beam 8 are fixedly connected with a fixing plate 12 through a pad 2, and a partition plate 5 is fixedly connected to the fixing plate 12. A waterproof cloth 1 is arranged between the two fixing plates 12. The waterproof cloth 1 is in direct contact with rainwater. By setting up an upper and lower two-layer waterproof structure, the waterproof cloth 1 directly bears rainwater and is used to discharge accumulated water. The top plate 9 is arranged inside as a second layer of waterproof structure.

[0045] A movable plate 6 is provided on the separated cross beam 8, and the upper surface of the movable plate 6 is fixedly connected to the waterproof cloth 1, wherein the waterproof cloth 1 is elastic and can be stretched. When it rains, rainwater will directly fall onto the waterproof cloth 1. Since the waterproof cloth 1 and the partition plate 5 are shielded to form a recessed area, rainwater can be accumulated in the recess, thereby forming a water layer on the surface of the waterproof cloth 1. The rainwater accumulated on the basis of the water layer is in direct contact with the water layer instead of 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 has a buffering effect on the rainwater that is hit, thereby avoiding the situation where 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 in the depression accumulates to a certain extent, due to the action of gravity, the spring sheet 23 is deformed by the downward pressure of the accumulated rainwater, and the slider 24 will slide along the surface of the beam 8 in the direction away from the adjusting block 25. During the movement of the slider 24, the adjusting block 25 will rotate accordingly, and the end of the movable plate 6 away from the connecting block 11 will tilt downward, and the slider 18 on the lower surface of the movable plate 6 will move in the slide groove 19. The inclination of the movable plate 6 will affect the shape of the depression, and the rainwater accumulated in the depression will directly overflow, thereby achieving the effect of discharging rainwater.

[0047] When the movable plate 6 tilts downward, it will also drive the water retaining plate 7 to move downward, and the side plate 13 on one side of the fixed block 14 will gradually move down to a position below the upper end of the pressing plate 16. When the adjusting block 25 rotates until the hypotenuse is close to the crossbeam 8, the pressing strip 20 on the hypotenuse of the adjusting block 25 will contact the second linkage shaft 21 and press the second linkage shaft 21 downward. The pressing strip 20 moves in an arc trajectory, so that the second linkage shaft 21 moves from the pressing plate 16 toward the direction of the rotating shaft 22. The second linkage shaft 21 will pull the pressing plate 16 to move, so that the upper end of the pressing plate 16 will cause an extrusion effect on the side plate 13. Under the extrusion effect, the side plate 13 will drive the water retaining plate 7 to flip over through the fixed block 14, then a gap will appear between the water retaining plate 7 and the waterproof cloth 1, and the remaining accumulated rainwater will directly leak out from the gap, realizing the discharge of rainwater. After the rainwater is discharged, the elastic force of the spring sheet 23 will reset the adjusting block 25 and the movable plate 6.

[0048] The implementation method of the steel structure roof structure, the steps are as follows:

[0049] Step 1, fix the bracket 4 on the top of the column 3, the bracket 4 is horizontally arranged, the cross beams 8 are symmetrically installed on both sides of the bracket 4, the top plate 9 is installed at the bottom between the two spaced cross beams 8, the top is installed with a fixing plate 12 through a pad 2, and the spacer plate 5 is installed through the fixing plate 12;

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

[0051] Step 3, the movable plate 6 is rotatably installed on both sides of the connecting block 11, and the adjusting block 25 is rotatably installed on the end of the crossbeam on the top of the top plate 9 away from the connecting block 11, and the pressing strip 20 and the spring sheet 23 are installed on the oblique side of the adjusting block 25. The end of the spring sheet 23 away from the adjusting block 25 is connected with the second slider 24, and the second slider 24 is slidably fitted on the crossbeam 8;

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

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

[0054] Step 6: When it rains, rain will directly fall onto the waterproof cloth 1, and a concave area will be formed by the shielding of the waterproof cloth 1 and the partition plate 5, so that a water layer will be formed on the surface of the waterproof cloth 1. The rainwater accumulated on the basis of the water layer will directly contact the water layer instead of 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 that hits down.

[0055] 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, and the slider 24 slides along the surface of the beam 8 in a direction away from the adjustment block 25. During the movement of the slider 24, the adjustment block 25 rotates accordingly, and the end of the movable plate 6 away from the connecting block 11 tilts downward, and the slider 18 on the lower surface of the movable plate 6 moves in the slide groove 19;

[0056] When the movable plate 6 tilts downward, the water retaining plate 7 will be driven to move downward at the same time, and the side plate 13 on the side of the fixed block 14 will gradually move down to a position below the upper end of the pressing plate 16. When the adjusting block 25 rotates until the bevel is close to the crossbeam 8, the pressing strip 20 on the bevel of the adjusting block 25 will contact the second linkage shaft 21 and press the second linkage shaft 21 downward. The pressing strip 20 moves in an arc trajectory, so that the second linkage shaft 21 moves from the pressing plate 16 toward the direction of the rotating shaft 22, and the second linkage shaft 21 will pull the pressing plate 16 moves, so that the upper end of the pressing plate 16 will cause an extrusion effect on the side plate 13. Under the extrusion effect, the side plate 13 will drive the water retaining plate 7 to flip over through the fixing block 14, and a gap will appear between the water retaining plate 7 and the waterproof cloth 1, and the remaining accumulated rainwater will directly leak out from the gap. After the rainwater is discharged, the elastic force of the spring sheet 23 will cause the adjusting block 25 and the movable plate 6 to reset. The center of gravity of the water retaining plate 7 when draining the accumulated water is always located on the side of the rotation center close to the connecting block 11, and it can be reset by gravity as soon as possible after the dumping is completed.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.

9. The method for implementing a waterproof and drainable steel roof structure according to claim 8, characterized in that: Here are the steps: Step 1, a bracket (4) is fixedly installed on the top of the column (3), the bracket (4) is arranged horizontally, cross beams (8) are symmetrically installed on both sides of the bracket (4), a top plate (9) is installed at the bottom between the two spaced cross beams (8), a fixing plate (12) is installed on the top through a pad (2), and a spacer plate (5) is installed through the fixing plate (12); Step 2: Install the connection block (11) on the bracket (4), the connection block (11) corresponds to the crossbeam (8) located on the top of the top plate (9), and the top is flush with the fixing plate (12); Step 3, the movable plates (6) are rotatably installed on both sides of the connecting block (11), and the adjusting block (25) is rotatably installed on the end of the cross beam on the top of the top plate (9) away from the connecting block (11), and the pressing strip (20) and the spring sheet (23) are installed on the oblique side of the adjusting block (25), and the end of the spring sheet (23) away from the adjusting block (25) is connected to the second slider (24), and the second slider (24) is slidably fitted on the cross beam (8); Step 4, install a mounting block (15) at one end of the crossbeam (8) at the bottom of the movable plate (6) away from the connecting block (11), and rotatably install a pressing plate (16) on the mounting block (15), install a first linkage shaft (17) on the pressing plate (16), rotatably install a second linkage shaft (21) on the free end of the first linkage shaft (17), and rotatably install a rotating shaft (22) on the free end of the second linkage shaft (21); Step 5, rotatingly installing the fixing block (14) on the top of the movable plate (6), installing the waterproof cloth (1) on the fixing plate (12) of the partition plate (5), installing the water retaining plate (7) on the fixing block (14), with both ends of the water retaining plate (7) located between the two partition plates (5), and the bottom being pressed onto the top surface of the waterproof cloth (1); Step 6: When it rains, rainwater will directly fall onto the waterproof cloth (1), and a concave area will be formed by the shielding of the waterproof cloth (1) and the partition plate (5), thereby forming a water layer on the surface of the waterproof cloth (1). Rainwater accumulated on the basis of the water layer will directly contact the water layer instead of the waterproof cloth (1). Rainwater will gradually accumulate, and the water layer will become thicker and thicker. Then, subsequent rainwater will directly hit the water layer with a certain thickness, which will have a buffering effect on the rainwater that hits down. When 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, and the slider (24) slides along the surface of the crossbeam (8) in a direction away from the adjustment block (25). During the movement of the slider (24), the adjustment block (25) rotates accordingly, and the end of the movable plate (6) away from the connecting block (11) tilts downward, and the slider (18) on the lower surface of the movable plate (6) moves in the slide groove (19); When the movable plate (6) tilts downward, the water retaining plate (7) is driven to move downward at the same time, and the side plate (13) on one side of the fixed block (14) gradually moves downward to a position below the upper end of the pressing plate (16). When the adjusting block (25) rotates until the oblique side is close to the cross beam (8), the pressing strip (20) on the oblique side of the adjusting block (25) contacts the second linkage shaft (21) and presses the second linkage shaft (21) downward. The pressing strip (20) moves in an arc track, so that the second linkage shaft (21) moves from the pressing plate (16) toward the direction of the rotating shaft (22). The second linkage shaft (21) pulls The pressing plate (16) moves, so that the upper end of the pressing plate (16) exerts a squeezing effect on the side plate (13). Under the squeezing effect, the side plate (13) drives the water retaining plate (7) to flip over through the fixing block (14), so that a gap appears between the water retaining plate (7) and the waterproof cloth (1), and the remaining accumulated rainwater directly leaks out from the gap. After the rainwater is discharged, the elastic force of the spring sheet (23) causes the adjustment block (25) and the movable plate (6) to reset. When draining the accumulated water, the center of gravity of the water retaining plate (7) is always located on the side of the rotation center close to the connecting block (11), and can be reset by gravity immediately after the dumping is completed.
