In the application, when the combined box girder vibrates to generate transverse dislocation, the limiting groove of the box body mechanism can extrude the stress mechanism, the second spring and the stress block are triangularly and elastically constrained, then the double elastic constraints of the second spring and the first spring limit the dislocation of the two box body mechanisms, and when the two box body mechanisms generate transverse left-right dislocation, the rolling ring will generate transverse left-right movement, the rolling ring will be stretched and compressed by the second spring on the two sides of the stress block to form constraint elastic force, thereby the two box body mechanisms generating transverse dislocation are constrained, the mounting effect between the two box body mechanisms is enhanced, and the influence of the continued dislocation under the vibration of vehicles on the flatness is avoided.

Description

Technical Field

[0001] This invention relates to the field of installation component technology, specifically to a concrete composite box girder installation component applied to highway construction. Background Technology

[0002] Currently, when using concrete composite box girders to construct highway viaducts, adjacent box girders are typically connected by connecting components. However, this connection method is prone to defects under long-term vibration from vehicle loads: First, lateral compression between box girders can easily lead to lateral misalignment or even breakage of the connecting components; second, component failure can directly cause stepped misalignment of adjacent box girders, affecting the flatness of the bridge deck; third, this misalignment can further widen the gap between box girders, creating a vicious cycle that ultimately threatens the stability of the overall structure. Summary of the Invention

[0003] This invention provides a concrete composite box girder installation component for highway construction, which overcomes the shortcomings described in the background art.

[0004] The technical solution adopted by the present invention to solve the above technical problems is as follows:

[0005] A concrete composite box girder installation component for highway construction includes a connecting plate, a support mechanism, a support strip, a box plate, a box body mechanism, and a splicing groove. The support strip is located at the upper end of the connecting plate, the support mechanism is symmetrically distributed on the left and right sides of the connecting plate, the splicing groove is located at the outer end of the box body mechanism, the box plate is provided at the upper end of the box body mechanism, and the box plate is horizontally aligned with the support strip. The support mechanisms on the left and right sides of the connecting plate are placed in the splicing groove, so that the connecting plate can be connected and fixed to two adjacent box body mechanisms.

[0006] The support mechanism has a central groove, a metal plate, and a spiral mechanism. There are six spiral mechanisms, which are horizontally distributed in a stepped manner inside the metal plate. The central groove is located inside the metal plate. When the spiral mechanism is twisted inside the metal plate, it will translate and lock the outside of the spiral mechanism inside the box mechanism. When two box mechanisms are misaligned, the two box mechanisms will simultaneously squeeze the spiral mechanism.

[0007] Furthermore, the box-shaped structure includes an entrance channel, a corner channel, and a concrete box; the entrance channel and the corner channel are located inside the concrete box, and the entrance channel and the corner channel are connected at a 90° angle; the corner channel is connected to the central groove, and workers can enter the corner channel through the entrance channel and fix the two box-shaped structures by turning the spiral mechanism on the side of the central groove.

[0008] Furthermore, the spiral mechanism includes a hexagonal block, a screw, a bearing block, a force-bearing mechanism, and a nut; the nut is secured inside the metal plate; the hexagonal block is fixed to the left end of the screw; a bearing block is provided at the right end of the screw, and the screw is screwed by rotating the hexagonal block, causing the screw to move spirally inside the nut; the force-bearing mechanism is fixed to the right end of the bearing block.

[0009] Furthermore, the inner side of the housing mechanism is provided with a limiting groove corresponding to the position of the force-bearing mechanism. The force-bearing mechanism is embedded in the limiting groove. When the screw is rotated, the bearing block will rotate and push the force-bearing mechanism, causing the force-bearing mechanism to translate in the direction of the limiting groove.

[0010] Furthermore, the force-bearing mechanism includes a convex block, a buffer structure, and a first spring; the convex block is connected to the side of the bearing block; the buffer structure is located on the outside of the convex block; the buffer structure is connected at an angle via the first spring, and when the housing mechanism is misaligned, it drives the buffer structure to squeeze the convex block through the limiting groove.

[0011] Furthermore, the buffer structure includes a rolling ring, a force-bearing block, a filler strip, and a second spring; the second spring is symmetrically fixed to the inner side of the rolling ring at a 30° angle; the inner side of the rolling ring is elastically connected to the outer side of the convex block by the filler strip; the second spring is symmetrically arranged and fixed on both sides of the force-bearing block, and is elastically constrained to the outer side of the convex block by the force-bearing block.

[0012] Compared with existing technologies, this technical solution has the following advantages:

[0013] In this invention, the operator enters from the entrance channel and corner channel of the box mechanism and screws the hexagonal block in the central groove, causing the screw to rotate inside the nut. The rotation of the screw pushes the force-bearing mechanism to move, and then the force-bearing mechanism abuts against the limiting groove on the inner side of the box mechanism. When the two box mechanisms are laterally misaligned due to vibration, the limiting groove of the box mechanism will squeeze the force-bearing mechanism, thereby elastically constraining the two box mechanisms and preventing the two box mechanisms from squeezing each other and causing the gap to widen, thus preventing instability. This ensures that the support bar and box plate are always in a horizontal position.

[0014] In this invention, when the two housing mechanisms are misaligned vertically, the inner wall of the limiting groove will press the rolling ring vertically. At this time, the first spring generates elastic tension and pressure on the second spring inside the rolling ring. The second spring and the force block form a triangular elastic constraint. Then, under the double elastic constraint of the second spring and the first spring, the misalignment of the two housing mechanisms is restricted. When the two housing mechanisms are misaligned laterally, the rolling ring also moves laterally. At this time, the second spring will generate tension and pressure to constrain the two misaligned housing mechanisms. Using the mounting component of this invention will enhance the installation effect between the two housing mechanisms and prevent misalignment from continuing under vehicle vibration, thus affecting the flatness of the structure.

Detailed Implementation

[0023] This invention proposes a concrete composite box girder installation component for use in highway construction, such as... Figures 1 to 6 As shown, the device includes a connecting plate 1, a support mechanism 2, a support bar 3, a box plate 4, a box body mechanism 5, and a splicing groove 6. The support bar 3 is disposed on the upper end of the connecting plate 1; the support mechanism 2 is symmetrically distributed on the left and right sides of the connecting plate 1; the splicing groove 6 is located at the outer end of the box body mechanism 5; the box plate 4 is disposed on the upper end of the box body mechanism 5, and the box plate 4 is horizontally aligned with the support bar 3; the support mechanism 2 is placed in the splicing groove 6, and the connecting plate 1 is used to connect and fix two adjacent box body mechanisms 5.

[0024] The support mechanism 2 is provided with a central groove 21, a metal plate 22 and a spiral mechanism 23; there are six spiral mechanisms 23, which are horizontally distributed in a stepped manner inside the metal plate 22; the central groove 21 is located inside the metal plate 22; the spiral mechanisms 23 rotate and translate within the metal plate 22, and the outside of the spiral mechanisms 23 is locked inside the box mechanism 5; when two box mechanisms 5 are about to misalign, they will simultaneously squeeze the spiral mechanisms 23 to prevent the two boxes from further misaligning.

[0025] Furthermore, the shape of the inner edge of the box mechanism 5 is the same as the shape of the outer edge of the support mechanism 2, and its size should ensure that the support mechanism 2 can be placed in the splicing groove 6; the support mechanism 2 is located inside the box mechanism 5; in order to ensure the strength of the components, the connecting plate 1 and the support bar 3 are both made of high-strength steel, and the interior of the connecting plate 1 and the support bar 3 is hollow, which can reduce the weight of the components.

[0026] Furthermore, the box mechanism 5 is placed on the pier, and the two box mechanisms 5 are fixedly connected to both sides of the connecting plate 1 through the support mechanism 2 to ensure that the two box mechanisms 5 remain stable and flat.

[0027] The box-shaped structure 5 includes an entrance channel 51, a corner channel 52, and a concrete box 53. The entrance channel 51 and the corner channel 52 are located inside the concrete box 53 and are connected at a 90° angle. The corner channel 52 is connected to the central groove 21. Workers can enter the corner channel 52 through the entrance channel 51 and rotate the spiral mechanism 23 on the side of the central groove 21. After rotation, the spiral mechanism 23 is fixed inside the box-shaped structure 5, and the two box-shaped structures 5 will be spliced ​​together.

[0028] The spiral mechanism 23 includes a hexagonal block 231, a screw 232, a bearing block 233, a force-receiving mechanism 234, and a nut 235. The nut 235 is secured inside the metal plate 22. The hexagonal block 231 is fixed to the left end of the screw 232. The bearing block 233 is provided at the right end of the screw 232. By rotating the screw 232 through the hexagonal block 231, the screw 232 can be spirally moved inside the nut 235. The force-receiving mechanism 234 is fixed to the right end of the bearing block 233.

[0029] The inner side of the housing mechanism 5 is provided with a limiting groove 101 corresponding to the alignment position of the force receiving mechanism 234, and the force receiving mechanism 234 is embedded in the limiting groove 101. When the screw 232 rotates and moves, the bearing block 233 will rotate and push the force receiving mechanism 234, causing the force receiving mechanism 234 to move in the opposite direction to the limiting groove 101.

[0030] Furthermore, the nut 235 is in a fixed state, while the outer side of the bearing block 233 has a hexagonal structure. The bearing block 233 can only move horizontally inside the metal plate 22 and cannot rotate. When the screw 232 is rotated and pushed by the hexagonal block 231, the bearing at the position of the bearing block 233 will be rotated, ensuring that the force-bearing mechanism 234 moves horizontally.

[0031] Furthermore, the limiting groove 101 is circular in shape. When the force-bearing mechanism 234 is embedded in the inner wall of the limiting groove 101, the metal plate 22 is located inside the splicing groove 6. The squeezing action between the two box mechanisms 5 is applied to the support mechanism 2, so that the circular limiting groove 101 limits the force-bearing mechanism 234, and avoids excessive squeezing force due to misalignment between the two box mechanisms 5, which could cause component damage.

[0032] The force-bearing mechanism 234 is provided with a convex block 41, a buffer structure 42 and a first spring 43; the convex block 41 is connected to the side of the bearing block 233; the buffer structure 42 is located outside the convex block 41; the buffer structure 42 is connected in an inclined manner through the first spring 43; when the housing mechanism 5 is misaligned, the buffer structure 42 is driven to squeeze the convex block 41 through the position of the limiting groove 101.

[0033] Furthermore, the outer side of the metal plate 22 is provided with a hollow groove. The function of the hollow groove is to allow the screw 232 to move horizontally and the convex block 41 to move within the hollow groove, so that when the metal plate 22 is placed in the splicing groove 6, the gap between the metal plate 22 and the splicing groove 6 is smaller.

[0034] In this invention, the operator enters from the entrance channel 51 and corner channel 52 of the box mechanism 5, and screws the hexagonal block 231 in the central groove 21, causing the screw 232 to rotate spirally in the nut 235. This causes the screw 232 to rotate and push the force-receiving mechanism 234 to move. Then, the force-receiving mechanism 234 is inserted into the limiting groove 101 on the inner side of the box mechanism 5. When the two box mechanisms 5 are laterally misaligned due to vibration, the limiting groove 101 will squeeze the force-receiving mechanism 234, causing the first spring 43 to exert a squeezing effect on the buffer structure 42. Under the dual elastic constraints of the buffer structure 42 and the first spring 43, the step-like misalignment caused by vibration of the two box mechanisms 5 is effectively suppressed, thereby avoiding the gap expansion and instability caused by mutual squeezing, and ensuring that the support bar 3 and the box plate 4 are always in a horizontal state.

[0035] Furthermore, when the screw mechanism 23 is twisted in the opposite direction, the force-bearing mechanism 234 will disengage from the limiting groove 101, thereby realizing the disassembly function and enabling the two box mechanisms 5 to be easily separated.

[0036] The buffer structure 42 includes a rolling ring 421, a force-bearing block 422, a filler strip 423, and a second spring 424. The second spring 424 is symmetrically fixed to the inner side of the rolling ring 421 at an inclination of 30°. The inner side of the rolling ring 421 is elastically connected to the outer side of the convex block 41 through the filler strip 423 and is symmetrically arranged. The second spring 424 is fixed on both sides of the force-bearing block 422 and elastically supported on the outer side of the convex block 41 by the force-bearing block 422.

[0037] Furthermore, the filler strip 423 is made of rubber. When the roller ring 421 is subjected to compression by the vertical misalignment of the housing mechanism 5, the filler strip 423 will generate elastic force on the roller ring 421, preventing the roller ring 421 from being directly compressed and damaged on the outside of the convex block 41.

[0038] Furthermore, there is a large gap between the force-bearing block 422 and the inner side of the rolling ring 421. This gap serves as a buffer space when the rolling ring 421 squeezes the convex block 41. There are eight force-bearing blocks 422 arranged in a ring, and each side is provided with a second spring 424. This structure can perform multi-directional elastic compression on the convex block 41. When the two box mechanisms 5 are misaligned in multiple directions, the convex block 41 will transmit the force to the rolling ring 421 through the inner wall of the limiting groove 101. At this time, the ring-arranged force-bearing blocks 422 can provide all-round elastic blocking. The second springs 424 on both sides of the force-bearing block 422 and the force-bearing block 422 form a triangular elastic constraint.

[0039] In this invention, when the two housing mechanisms 5 are vertically misaligned, the inner wall of the limiting groove 101 will press the rolling ring 421 vertically. At this time, the first spring 43 provides elastic constraint to the second spring 424 on the inner side of the rolling ring 421, and the two second springs 424 and the force block 422 form a triangular elastic constraint. Under the dual elastic constraint of the second spring 424 and the first spring 43, the misalignment of the two housing mechanisms 5 is restricted. When the two housing mechanisms 5 are horizontally misaligned, the rolling ring 421 will move horizontally to the left and right. The second springs 424 on both sides of the force block 422 provide effective elastic constraint for the housing mechanism 5 through their tension and compression. This constraint can significantly suppress the misalignment that may be caused by vehicle vibration, thereby ensuring that the housing always remains flat and stable.

[0040] The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.
