Description

Technical Field

[0001] This invention relates to the field of steel bridge deck technology, specifically to a steel bridge deck for bridges and a connection method thereof. Background Technology

[0002] Bridge engineering refers to the processes of bridge surveying, design, construction, maintenance, and inspection, as well as the science and engineering technology that studies these processes. It is a branch of civil engineering. The development of bridge engineering is primarily driven by the needs of transportation. Ancient bridges were mainly for pedestrian and animal traffic, with relatively light loads, allowing for steep longitudinal slopes and even the construction of steps. In terms of construction materials, high strength, lightweight, and low cost were the main selection criteria, with traditional steel and concrete being the primary materials used to improve their strength and durability. Steel bridge decks were required during bridge construction to facilitate road paving.

[0003] Application number 202120042460.6, entitled "A Connection Structure for a Bridge Deck," describes a method for sealing bridge decks. The method involves aligning a pad 41 with the first hollow plate 1 and the second hollow plate 3. After alignment, the pad 41 is pushed, causing the connecting plate 42 to slide. The connecting plate 42 then slides the second spring 43, which in turn slides the abutment 44. The abutment 44 then slides the sealing gasket 45. When the abutment 44 contacts the first hollow plate 1 and the second hollow plate 3, it will... The sliding action involves the abutment plate 44 driving the second spring 43 to slide. The second spring 43 serves to bring the abutment plate 44 into contact with the first hollow plate 1 and the second hollow plate 3. That is, the second spring 43 applies a pushing force to the abutment plate 44, causing the sealing gasket 45 to adhere to the first hollow plate 1 and the second hollow plate 3, thus achieving a sealing effect. However, the elasticity of the spring is limited, and after long-term use, the adhesion between the sealing gasket 45 and the two hollow plates will be affected, thereby affecting the sealing effect. At the same time, the two hollow plates are connected by a snap-fit ​​mechanism, and the stability of the connection between the two needs to be strengthened. Summary of the Invention

[0004] The purpose of this invention is to provide a steel bridge deck and connection method for bridges, which can improve the stability and tightness of the connection between two hollow plates, facilitate subsequent use, and the compressed spring drives the positioning block to return to its original position, so that the positioning block connects with the limiting groove, realizes automatic locking of the connector, fixes the moving block, and prevents the connection between the two hollow plates from loosening due to accidental rotation of the handle. It has the advantages of safe and reliable use and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel bridge deck for bridges, comprising two hollow plates and two cover plates connected between the two hollow plates, wherein the cover plates are connected to two pressure blocks, and the cover plates are matched with connecting grooves provided at both ends of the hollow plates, the connecting grooves are provided with pressure grooves, the pressure grooves are matched with the pressure blocks, and the cover plates are connected to a driving mechanism for driving the two cover plates to move closer or further apart, the driving mechanism comprising four push-pull plates, two moving blocks, studs, and a handle, the handle being used to drive the studs to rotate, the studs being used to drive the two moving blocks to move closer or further apart, the two ends of the push-pull plates being connected to the corresponding moving blocks and cover plates, and the handle being connected to a locking mechanism for locking the moving blocks;

[0006] When two hollow plates are connected, the cover plate is pressed against the corresponding connecting groove, the pressure block is pressed against the pressure groove, and the locking mechanism is locked against the moving block.

[0007] Preferably, the connecting groove has a stepped structure and is provided with a vertical surface one and a vertical surface two, with the vertical surface two located on the lower side of the vertical surface one.

[0008] Preferably, the cover plate has a T-shaped cross-section, and sealing gaskets are connected to both sides of the cover plate, the sealing gaskets matching the corresponding vertical surfaces one and two.

[0009] Preferably, the stud passes through the two movable blocks and is threadedly connected to the movable blocks, with the internal threads of the two movable blocks in opposite directions.

[0010] Preferably, the two ends of the push-pull plate are connected to the corresponding moving block and cover plate via shafts.

[0011] Preferably, the locking mechanism includes a connecting seat, a slot, a cylinder, a connecting handle, a spring, an inner cavity, a sliding block, a positioning block, an inclined surface, and a lifting column. The slot is disposed within the connecting seat, and the connecting seat is fixedly connected to the handle. The end of the stud is inserted into the slot and fixedly connected to the connecting seat. The cylinder is connected to the slot. Both ends of the lifting column are connected to the connecting handle and the positioning block. The sliding block is used to guide the lifting column. The spring is used to drive the sliding block to move towards the positioning block. The inclined surface is disposed on one side of the bottom of the positioning block.

[0012] Preferably, the side of the movable block is connected to a connector that matches the slot, and the connector is provided with a limiting groove that matches the positioning block.

[0013] Preferably, the limiting groove is an annular groove.

[0014] Preferably, the inner cavity is located inside the cylinder, the spring is located inside the inner cavity and is sleeved on the lifting column, and both ends are connected to the sliding block and the end of the inner cavity, and the sliding block is slidably connected to the inner cavity.

[0015] A method for connecting steel bridge deck panels includes the following steps:

[0016] Step 1: Align the two hollow plates, then connect the two cover plates to the corresponding connecting grooves, and align the pressure block with the pressure groove. Then rotate the handle to drive the stud to rotate, so that the two moving blocks move away from each other. That is, the moving blocks apply a pulling force to the corresponding push-pull plates, and the push-pull plates apply a pulling force to the cover plates, so that the two cover plates move closer to each other, while the connector moves towards the connecting seat.

[0017] Step 2: The connector is gradually inserted into the slot, and the end of the connector slides on the inclined surface, which can lift the sliding block, compress the spring, and move the sliding block, lifting column, and connecting handle upwards simultaneously. At the same time, the pressure block is gradually pressed into the pressure groove, which can drive the two hollow plates to move closer to each other, with vertical surface one and vertical surface two moving closer to the corresponding sealing gaskets respectively.

[0018] Step 3: When the end of the connector is connected to the end face of the slot (the connector cannot move forward further), the push-pull plate is pulled tight against the cover plate, the cover plate is pressed against the connecting groove, the pressure block is pressed against the pressure groove, and vertical surfaces one and two are pressed against the corresponding sealing gaskets. This can improve the stability and tightness of the connection between the two hollow plates. The compressed spring drives the positioning block to return to its original position, so that the positioning block is connected with the limiting groove, realizing automatic locking of the connector and fixing of the moving block, preventing the two hollow plates from loosening due to accidental rotation of the handle.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention is equipped with a driving mechanism and a locking mechanism. The driving mechanism includes four push-pull plates, two moving blocks, a stud, and a handle. The locking mechanism includes a connecting seat, a slot, a cylinder, a connecting handle, a spring, an inner cavity, a sliding block, a positioning block, an inclined surface, and a lifting column. When two hollow plates are joined, the two cover plates can be connected to the corresponding connecting slots. Rotating the handle drives the stud to rotate, causing the two moving blocks to move away from each other. The moving blocks apply a pulling force to the corresponding push-pull plates, driving the two cover plates to move closer together. At the same time... The connector moves into the slot. When the end of the connector connects with the end face of the slot (the connector cannot move forward further), the push-pull plate is pulled tight against the cover plate, the cover plate is pressed against the connecting groove, the pressure block is pressed against the pressure groove, and vertical surfaces one and two are pressed against the corresponding sealing gaskets. This improves the stability and tightness of the connection between the two hollow plates, facilitating subsequent use. The compressed spring drives the positioning block to return to its original position, connecting the positioning block with the limiting groove, thus automatically locking the connector and fixing the moving block. This prevents the two hollow plates from loosening due to accidental rotation of the handle, ensuring safe and reliable use. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1 to 7This invention provides a steel bridge deck for bridges, comprising two hollow plates 1 and two cover plates 2 connected between the two hollow plates 1. The length of the cover plate 2 is equal to the width of the hollow plate 1. Two pressure blocks 5 are connected to the cover plate 2, and the cross-section of the pressure blocks 5 is a right-angled triangular structure. The cover plate 2 matches the connecting grooves 22 located at both ends of the hollow plates 1. The connecting grooves 22 are provided with pressure grooves 24, which match the pressure blocks 5. When the pressure blocks 5 are gradually pressed against the pressure grooves 24, the two hollow plates 1 are driven to move closer to each other, that is, vertical surfaces 21 and 23 move towards the corresponding sealing gaskets 4, until the pressure blocks 5 are pressed tightly against the pressure grooves 24, and vertical surfaces 21 and 23 are pressed tightly against the corresponding sealing gaskets 4. This improves both the stability of the connection between the two hollow plates 1 and the sealing performance of the connection with the cover plate 2. The cover plate 2 is connected to a drive mechanism for driving the two cover plates 2 to move closer or further apart. The drive mechanism includes four push-pull plates 9, two moving blocks 8, studs 10, and handles 3. The handles 3 are used to drive the studs 10 to rotate, and the studs 10 are used to drive the two moving blocks 8 to move closer or further apart. The two ends of the push-pull plates 9 are connected to the corresponding moving blocks 8 and cover plates 2. The handles 3 are connected to a locking mechanism for locking the moving blocks 8.

[0030] When two hollow panels 1 are joined, two cover plates 2 can be connected to the corresponding connecting grooves 22. Rotating the handle 3 drives the stud 10 to rotate, causing the two moving blocks 8 to move away from each other. The moving blocks 8 apply a pulling force to the corresponding push-pull plates 9, driving the two cover plates 2 to move closer together. At the same time, the connector 7 moves into the slot 12. When the end of the connector 7 is connected to the end face of the slot 12 (the connector 7 cannot move further forward), the push-pull plate 9 is pulled tight against the cover plate 2, the cover plate 2 is pressed against the connecting groove 22, the pressure block 5 is pressed against the pressure groove 24, and the vertical surfaces 21 and 23 are pressed against the corresponding sealing gaskets 4, which can improve the stability and tightness of the connection between the two hollow panels 1, and facilitate subsequent use. The compressed spring 15 drives the positioning block 18 to return to its original position, so that the positioning block 18 is connected to the limiting groove 13, realizing automatic locking of the connector 7 and fixing of the moving blocks 8, preventing the two hollow panels 1 from loosening due to accidental rotation of the handle 3, ensuring safe and reliable use.

[0031] When the two hollow plates 1 need to be separated, the connecting handle 14 can be lifted to move the lifting column 20 upward, and simultaneously move the sliding block 17 and the positioning block 18 upward, so that the positioning block 18 separates from the limiting groove 13, thereby loosening the connecting head 7. Then, the handle 3 is rotated (counterclockwise) to drive the stud 10 to rotate, so that the two moving blocks 8 move closer to each other, so that the moving blocks 8 apply a pushing force to the corresponding push-pull plate 9, so that the two cover plates 2 move away from each other, that is, the pressure block 5 separates from the pressure groove 24, and the cover plate 2 separates from the connecting groove 22, thereby simultaneously loosening the two hollow plates 1 and facilitating separation.

[0032] The connecting groove 22 has a stepped structure and is provided with a vertical surface 21 and a vertical surface 23, with the vertical surface 23 located on the lower side of the vertical surface 21. When the pressing block 5 is pressed into the corresponding pressing groove 24, the top of the cover plate 2 is aligned with the top of the hollow plate 1, which facilitates the subsequent laying of the panels.

[0033] The cover plate 2 has a T-shaped cross-section and is made of high-strength steel, which has good compressive strength and sufficient toughness to prevent bending deformation at the joint when the two hollow plates 1 are connected. Sealing gaskets 4 are connected to both sides of the cover plate 2, and the sealing gaskets 4 match the corresponding vertical surfaces 21 and 23.

[0034] The stud 10 passes through the two movable blocks 8 and is threadedly connected to the movable blocks 8. The internal threads of the two movable blocks 8 are in opposite directions. When the stud 10 rotates clockwise, it can drive the two movable blocks 8 away from each other, apply a pulling force to the push-pull plate 9, and drive the two cover plates 2 to move closer to each other. When the stud 10 rotates counterclockwise, it can drive the two movable blocks 8 to move closer to each other, apply a pushing force to the push-pull plate 9, and drive the two cover plates 2 to move away from each other.

[0035] The two ends of the push-pull plate 9 are connected to the corresponding moving block 8 and cover plate 2 via shafts.

[0036] The locking mechanism includes a connecting seat 11, a slot 12, a cylinder 6, a connecting handle 14, a spring 15, an inner cavity 16, a sliding block 17, a positioning block 18, an inclined surface 19, and a lifting column 20. The slot 12 is located inside the connecting seat 11, and the connecting seat 11 is fixedly connected to the handle 3. The end of the stud 10 is inserted into the slot 12 and fixedly connected to the connecting seat 11. The cylinder 6 is connected to the slot 12. The two ends of the lifting column 20 are connected to the connecting handle 14 and the positioning block 18. The sliding block 17 is used to guide the lifting column 20. The spring 15 is used to drive the sliding block 17 to move closer to the positioning block 18. The inclined surface 19 is located on one side of the bottom of the positioning block 18. As connector 7 is gradually inserted into slot 12, the end of connector 7 connects with inclined surface 19, which can lift positioning block 18. That is, connector handle 14, lifting column 20, and sliding block 17 rise synchronously, and spring 15 is compressed. When the end of connector 7 connects with the end of slot 12, connector 7 cannot move forward. Positioning block 18 and limiting groove 13 are aligned. The compressed spring 15 drives sliding block 17 back to its original position, which in turn drives connector handle 14, lifting column 20, and positioning block 18 back to their original positions, so that positioning block 18 is inserted into limiting groove 13. That is, the vertical surface of positioning block 18 is connected to the side of limiting groove 13, which plays a good limiting role for connector 7 and prevents the moving block 8 from loosening due to accidental rotation of handle 3.

[0037] The side of the movable block 8 is connected to a connector 7 that matches the slot 12. The connector 7 is provided with a limiting groove 13 that matches the positioning block 18. The limiting groove 13 is an annular groove.

[0038] The inner cavity 16 is located inside the cylinder 6, and the spring 15 is located inside the inner cavity 16. The spring 15 is sleeved on the lifting column 20, and its two ends are connected to the sliding block 17 and the end of the inner cavity 16. The sliding block 17 is slidably connected to the inner cavity 16. The sliding block 17 plays a guiding and limiting role on the positioning block 18, so that the lifting is stable.

[0039] A method for connecting steel bridge deck panels includes the following steps:

[0040] Step 1: Align the two hollow plates 1, then connect the two cover plates 2 with the corresponding connecting grooves 22, and align the pressure block 5 with the pressure groove 24. Then rotate the handle 3 to drive the stud 10 to rotate, so that the two moving blocks 8 move away from each other. That is, the moving blocks 8 apply a pulling force to the corresponding push-pull plates 9, and the push-pull plates 9 apply a pulling force to the cover plates 2, so that the two cover plates 2 move closer to each other, while the connector 7 moves toward the connector seat 11.

[0041] Step 2: The connector 7 is gradually inserted into the slot 12, and the end of the connector 7 slides on the inclined surface 19, which can lift the sliding block 17, compress the spring 15, and move the sliding block 17, the lifting column 20, and the connecting handle 14 upwards simultaneously. At the same time, the pressure block 5 is gradually pressed against the pressure groove 24, which can drive the two hollow plates 1 to move closer to each other, and the vertical surface 1 21 and the vertical surface 23 move closer to the corresponding sealing gasket 4 respectively.

[0042] Step 3: When the end of connector 7 is connected to the end face of slot 12 (connector 7 cannot move forward further), push-pull plate 9 is pulled tight to cover plate 2, cover plate 2 is pressed to connecting groove 22, pressure block 5 is pressed to pressure groove 24, vertical surface 1 21 and vertical surface 2 23 are pressed to the corresponding sealing gasket 4, which can improve the stability and tightness of the connection between the two hollow plates 1. The compressed spring 15 drives positioning block 18 back to its original position, so that positioning block 18 is connected to limiting groove 13, realizing automatic locking of connector 7 and fixing of moving block 8, preventing the two hollow plates 1 from loosening due to accidental rotation of handle 3.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
