Description

Technical Field

[0001] The invention relates to the technical field of industrial buildings, and in particular to a cement clinker yard with an ultra-large span grid structure and a construction method. Background Art

[0002] As an indispensable building material, cement is in great demand, and a warehouse for storing cement is needed. Traditional cement warehouses use concrete central columns as roofs, which have many disadvantages: first, the zipper machine platform of the cement warehouse of the production line is usually higher than the ground, and the impact of cement on the concrete central column is very large. According to statistics, the concrete central column will be seriously damaged after two to four years of use; second, the cement warehouse is a closed cylinder with only a small entrance and exit, and large machinery and equipment cannot enter and exit. Once the concrete central column is damaged, the entire line needs to be stopped for repair, which is difficult and costly to repair; third, after the concrete central column is seriously damaged, it will cause a greater safety hazard, and in severe cases, the roof will collapse. At the same time, the environment inside the cement warehouse is harsh and it is difficult to monitor the damage. In recent years, large-span steel grids have been used to replace traditional column roofs for the construction of cement warehouses, and the construction methods are different.

[0003] A cement clinker silo with announcement number CN101691823A includes a concrete silo and a clinker silo roof. The clinker silo roof is a steel grid structure. A clinker silo roof and a pulling machine truss are arranged above the center of the steel grid structure. The characteristic is that the clinker silo roof is a full-span steel grid structure, that is, all supporting structures of the clinker silo roof are arranged on the upper end of the concrete silo, and the supporting structures of the clinker silo roof are all roof sliding supports. The structure of the roof sliding supports is fixed on the concrete silo, and the sliding structure of the roof sliding supports is to make the clinker silo roof slide radially along its own steel grid structure.

[0004] The announcement number is CN114482379A, which is a steel roof structure of a clinker silo that uses a combination of welded balls and bolted balls. The structure includes a clinker silo top truncated cone grid, a silo roof structure, a zipper machine and a conveying gallery. The clinker silo top truncated cone grid includes a clinker silo grid support, a round steel pipe, a bolt ball node, a welded ball node, a main purlin, a secondary purlin, a patterned steel plate, a support and rock wool. The clinker silo grid support includes an embedded part, an elastic support and a clinker silo support node plate; the silo roof structure includes a It includes H-shaped steel beams at the roof slab elevation of the warehouse, H-shaped steel column structures of the warehouse, H-shaped steel beam-column connection nodes of the warehouse, circumferential H-shaped steel beams of the warehouse and bolt balls with welded H-beams. The H-shaped steel column structure of the warehouse roof includes H-shaped steel columns of the warehouse roof, node plates at the base of H-shaped steel columns of the warehouse roof, supports between columns of the warehouse roof, stiffening ribs and high-strength bolts. The H-shaped steel beam-column connection nodes of the warehouse roof include H-shaped steel columns of the warehouse roof, radial H-shaped steel beams of the warehouse roof, end plates, stiffening ribs, connection plates and high-strength bolts.

[0005] Based on the above scheme, cement clinker yards are mostly used to store cement. The yards are used to block bad weather and prevent cement from being damaged. The tops of most yards are fixed with pillars, but the pillars are easily damaged by the pressure of the cement accumulated inside during use. When encountering strong winds, the pillars cannot withstand the strong winds and collapse, causing unnecessary waste. At the same time, the existence of the pillars also affects the internal loading capacity. Although some of them use grids as the top and do not need to use columns, in actual use, the grid structure is light in overall weight and may be deformed when subjected to strong winds. In severe cases, the grid structure may be directly overturned. Summary of the invention

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] First embodiment

[0037] The present invention provides Figures 1 to 8The cement clinker yard of the ultra-large span grid structure shown in the figure includes a wall 1, which is composed of bricks, concrete and steel bars, has strong strength, and can adapt to various severe weather conditions. The shape of the wall 1 is cylindrical. When encountering strong wind weather, the wind can pass along the surface of the wall 1, reducing the impact of the wind on the wall 1, thereby increasing the overall service life. An adjustment component 2 is provided at the upper end of the wall 1. The adjustment component 2 can freely adjust the position of the positioning rod 13 to keep the magnet 14 away from the iron plate 9, thereby releasing the constraint on the cover plate 8, so that the lower end of the cover plate 8 can be freely lifted, so that the strong wind can directly pass from under the cover plate 8. The air flow rate here is increased, and the lower the air flow rate, the lower the pressure, which can attract the humid air inside the wall 1 and discharge the moisture through the wind, so as to achieve the purpose of air circulation and prevent the cement from getting damp due to the high air humidity inside the wall 1. The adjustment component 2 includes a mounting ring 201, and a second annular groove 202 is provided on the upper surface of the mounting ring 201, so that the positioning block 203 can move along the trajectory of the second annular groove 202 to avoid misalignment. The inside of the second annular groove 202 The sliding connection has a group of positioning blocks 203 arranged in a circle, and the upper surface of each positioning block 203 is fixedly connected to the lower end of the positioning rod 13. An expansion tube 204 is provided between every two adjacent positioning blocks 203. The expansion tube 204 is made of rubber material. When the internal gas increases, it can expand, increase its volume, and push the positioning blocks 203 in contact at both ends to move. A first spring 15 is provided between every two adjacent sliders 12, and each first spring 15 is in an arc shape. When the positioning block 203 drives the positioning rod 13 and the slider 12 to move in turn, the first spring 15 can be subjected to Force, after the force disappears, under the action of elasticity, the positioning block 203 can be restored to its original position to prepare for the next adjustment. A group of stirring blades 16 arranged in a circle are provided at the lower part of the outer surface of the rotating ring 6. When the rotating ring 6 drives the stirring blades 16 to rotate, the gas inside the space between the cover plate 8 and the frame 3 can circulate. Since the faster the gas flow rate, the lower the pressure, the gas inside the wall 1 can be introduced into the space between the cover plate 8 and the frame 3 through the air intake assembly 5, so that the air pressure inside this space is increased, which plays a certain supporting role on the cover plate 8, making it stronger and more wind-resistant.

[0038] A frame 3 is provided on the bottom surface of the adjustment component 2, and a relatively sealed space can be formed between the frame 3 and the multiple cover plates 8. When the gas in the space increases, the cover plates 8 can be effectively prevented from being deformed by wind. A feeding component 4 is provided on the upper surface of the frame 3. The feeding component 4 can introduce materials from above into the wall 1, thereby achieving the purpose of storing cement and avoiding loss due to bad weather. The feeding component 4 includes a feeding barrel 401, which can effectively introduce materials into the wall 1 to achieve the purpose of storing materials, and the feeding barrel 401 is small in size to prevent excessive gas from entering the interior. A stop valve is provided inside the feeding barrel 401, which can effectively cut off the feeding barrel 401 to prevent external debris from entering the interior. In order to pollute the internal cement, a rain shield plate 402 is provided in the middle of the outer surface of the feed barrel 401, and the upper surface of the rain shield plate 402 is inclined. The rain shield plate 402 can effectively cover the connecting component 7 to prevent rainwater from directly contacting the connecting component 7. On the contrary, the connecting component 7 will be damaged by moisture. Under the action of the inclined surface, the accumulated water can be effectively discharged to avoid accumulation. The outer surface of the frame 3 is provided with a plurality of air intake components 5 arranged in a circle. When strong wind moves along the trajectory of the frame 3, the air flow rate here is increased. The faster the gas flow rate, the lower the pressure, which can cause the humid gas inside the wall 1 to be attracted through the air intake component 5, and the moisture is discharged by wind, thereby achieving the purpose of air circulation and preventing the high air humidity inside the wall 1 from making the cement damp.

[0039] The air intake assembly 5 includes a first air intake pipe 501, and a gas collecting bucket 502 is provided at the lower end of the first air intake pipe 501. The air inlet of the gas collecting bucket 502 is larger than the air outlet, so that the gas collecting bucket 502 covers a wider range when absorbing gas, and collects humid gas more quickly. A one-way valve is provided inside the first air intake pipe 501. When the gas at the lower end of the first air intake pipe 501 enters the space between the cover plate 8 and the frame 3 through the one-way valve, the air pressure inside the space is increased, so that the multiple cover plates 8 can be propped up to improve their strength, thereby preventing the cover plates 8 from being deformed by strong winds and causing unnecessary damage. The outer surface of the first air intake pipe 501 is provided with two symmetrical second air intake pipes 503, and the other end of each second air intake pipe 503 is provided with a symmetrical second air intake pipe 503. One end is connected to the expansion tube 204 close to each other, the second air inlet pipe 503 and the first air inlet pipe 501 can introduce gas into the expansion tube 204, so that the internal gas increases and expands, and under the effect of extrusion, the positioning block 203 is pushed to drive the positioning rod 13 to move, so as to achieve the purpose of freely adjusting the positioning rod 13, and the outer surface of the feed component 4 is sleeved with a rotating ring 6, which can play a certain supporting role. When the cover plate 8 rotates, it can drive the rotating ring 6 to rotate to avoid interference. The upper surface of the rotating ring 6 is provided with a group of connecting components 7 arranged in a circle, and the connecting component 7 can splice multiple cover plates 8 together so that the multiple cover plates 8 can move synchronously.

[0040] The other end of each connecting component 7 is provided with a cover plate 8, the bottom surface of each cover plate 8 is provided with an iron plate 9, and the upper surface of each cover plate 8 is provided with a plurality of windshield strips 10 arranged in a circular arc. When the wind force contacts the windshield strips 10, under the action of the wind force, the plurality of cover plates 8 can be driven to rotate, thereby being able to unload part of the wind force and reducing the impact of the wind force on the cover plates 8, thereby improving the overall wind resistance. A first annular groove 11 is provided on the outer surface of the rotating ring 6, and a slider 12 is slidably connected to the inside of the first annular groove 11. A positioning rod 13 is provided on the outer surface of each slider 12, and a magnet 14 is provided on the outer surface of each positioning rod 13, and each magnet 14 corresponds to the iron plate 9. There is magnetic force between the magnet 14 and the iron plate 9, which can position the cover plate 8 to prevent the cover plate 8 from being misplaced after the rotation stops. When the cover 8 rotates, when there is magnetic force between the magnet 14 and the iron plate 9, a large wind force is required to break through this limit. When the wind force becomes smaller, it can prompt the cover 8 to move to the magnetic position and stop rotating. The connecting component 7 includes a first connecting block 701, and the outer surface of the first connecting block 701 is hinged with a second connecting block 702. Through the mutual cooperation of the first connecting block 701 and the second connecting block 702, the cover 8 can be swung upward along the rotation axis of the first connecting block 701, and the bottom of the cover 8 is opened to allow wind to pass quickly, thereby avoiding damage to the whole due to excessive wind force. Two symmetrical torsion springs 703 are arranged between the first connecting block 701 and the second connecting block 702. When the cover 8 follows the second connecting block 702 to be lifted upward, the torsion spring 703 can be subjected to force to prevent the movement from being too large.

[0041] A constraint ring 17 is sleeved between the outer surfaces of the wall 1 and the adjustment component 2. The constraint ring 17 can effectively splice the wall 1 and the adjustment component 2 together, and prevent the cover plate 8 from being lifted up by wind by constraining the lower end of the cover plate 8. The inner wall of the constraint ring 17 is in contact with the lower end of each cover plate 8. An air intake ring 18 is provided on the upper surface of the constraint ring 17. When the gas entering the air intake ring 18 through the cover plate 8 gradually increases, it can push the constraint ring 17 to move downward to increase the distance, thereby releasing the constraint on the lower end of the cover plate 8. A group of sleeves 19 arranged in a circle are provided on the upper part of the outer surface of the wall 1, and a push rod 20 is slidably connected to the inside of each sleeve 19. The upper end of each push rod 20 is fixedly connected to the bottom surface of the constraint ring 17, and a second spring 21 is provided between each sleeve 19 and the push rod 20. Through the mutual cooperation of the push rod 20, the sleeve 19 and the second spring 21, resistance to the downward movement of the constraint ring 17 can be provided, and the greater the downward distance, the greater the corresponding resistance, and a larger wind force is required to release the constraint on the lower end of the cover plate 8.

[0042] During feeding, cement is transported from the ground to a high place through a feeding device, and the stop valve is opened to open the feeding cylinder 401. Under the action of gravity, cement is sequentially allowed to enter the interior of the wall 1, thereby achieving the purpose of storage.

[0043] In actual use, when the wind force is lower than the first threshold, the wind force is relatively small and the following adjustments are required:

[0044] Under the influence of wind, the windshield strips 10 can move in the wind direction, thereby prompting the multiple cover plates 8 to rotate, thereby removing the wind force through rotation, reducing the impact of wind force on the cover plates 8, thereby improving the overall wind resistance and avoiding damage.

[0045] When the wind force is greater than the first threshold, the wind force is gradually increasing. At this time, rotation is not enough to remove the wind force. The following adjustments are required:

[0046] Under the influence of wind, the speed of the windshield strip 10 moving in the wind direction can be gradually increased, thereby prompting the multiple cover plates 8 to increase their rotation speed. Under the cooperation of the connecting component 7 and the rotating ring 6, the stirring blade 16 below can be driven to rotate, prompting the gas inside the space between the cover plate 8 and the frame 3 to circulate. Since the faster the gas flow rate, the lower the pressure, it can drive the gas inside the wall 1 to enter the first air inlet pipe 501 through the gas gathering bucket 502, and then enter the space between the cover plate 8 and the frame 3 through the one-way valve, so that the air pressure inside this space is increased, so that the multiple cover plates 8 can be propped up to improve their strength, avoiding deformation of the cover plates 8 caused by strong winds and causing unnecessary damage. The greater the wind force, the faster the stirring blade 16 rotates, and the more gas enters the space, so that the strength of this space is gradually increased, avoiding deformation of the cover plate. At the same time, the air pressure can also play a certain buffering role to avoid damage to the whole due to excessive wind at a certain moment.

[0047] When the wind force is greater than the second threshold, the wind force increases again. In order to prevent the overall collapse, the following adjustments need to be made:

[0048] Under the impact of strong wind, the cover plate 8 in the windward direction is deformed, the space between the cover plate 8 and the frame 3 becomes smaller, the internal air is compressed, and the gas enters the expansion tube 204 through the nearest first air inlet pipe 501 and the second air inlet ring 18 in turn, so that the gas inside the expansion tube 204 increases and expands. Under the effect of squeezing, the two symmetrical positioning blocks 203 located on the front and back sides are pushed along the second annular groove 202 to drive the positioning rod 13 to move. Under the effect of the positioning rod 13, the magnet 14 is driven away from the iron plate 9 to release the constraint of the cover plate 8 at that position, and at the same time, the slider 12 is driven to move, causing the first spring 15 to compress and generate a restoring elastic force. Part of the strong wind will enter the interior of the air inlet ring 18 below along the deformed cover plate 8. Under the effect of wind pressure, the constraint ring 17 is pushed to move downward gradually until it is released. In addition to the constraint on the lower end of the cover 8, when the cover 8 rotates to the side, since the magnets 14 are mostly gathered on the right side at this time, they cannot generate suction on the iron plate 9. Under the action of centrifugal force and wind force, the cover 8 can swing upward along the rotation axis of the connecting component 7, so that the cover 8 is opened, and strong wind can pass from under the cover 8, so as to avoid the cover 8 being blown away by excessive wind and causing unnecessary damage. When the strong wind moves along the trajectory of the frame 3, the air flow rate here increases, and the gas flow rate becomes lower and lower, which can attract the humid gas inside the wall 1 and discharge the moisture through wind force, thereby achieving the purpose of air circulation and preventing the high air humidity inside the wall 1 from making the cement damp. When the strong wind gradually becomes smaller, each component can be reset and re-fixed under the action of elasticity without affecting subsequent use.
