Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to an assembled bearing platform for box beam construction. Background Art

[0002] In modern bridge construction, box girder is a common structural form. As a widely adopted bridge structure, box girder is widely used in various bridge projects for its excellent stress-bearing performance and stability. The box girder is shaped like a box and has a closed cross-section. This structural form enables the box girder to effectively disperse and transmit force when bearing loads, thereby ensuring the stability and safety of the bridge. The construction of box girders usually requires precise and efficient operating platforms to ensure construction quality and safety.

[0014] Compared with the prior art, the assembled load-bearing platform for box girder construction has the following beneficial effects:

[0015] 1. The utility model makes it more convenient to insert the anchor into the ground through the inverted trapezoidal design of the anchor, and simplifies the insertion process. When the embedded pile is inserted into the ground, the push block is lifted and lowered along the vertical direction of the embedded pile by the telescopic column. When the push block descends, the bevels on both sides of the bottom slide along the surface of the linkage block, and the linkage block slides outward through the slider and the telescopic spring. When the push block falls to the bottom, the two sides of the push block push the linkage block to the maximum position, and the linkage block extends the external expansion wing out of the embedded pile, so that the expansion wing can extend out of the ground on both sides of the embedded pile. The embedded pile is more stable when fixed by the expansion wing. The extension of the expansion wing not only enhances the contact area with the surrounding soil, but also effectively prevents soil erosion and loosening, thereby ensuring that the embedded pile remains stable during long-term use, so that the bearing platform can maintain stability under different terrains. When the embedded pile needs to be taken out, the telescopic column drives the push block to rise, and the linkage block loses the extrusion of the push block, and the telescopic spring drives the linkage block to retract, and at the same time controls the external expansion wing to retract inward, so as to smoothly take out the embedded pile.

[0016] 2. The utility model has a fixing end fixed at the bottom end of the bearing platform, and a limiting groove is provided inside the fixing end. The limiting groove and the limiting block cooperate with each other, and the limiting block is pushed to the bottom by the telescopic rod, and the limiting block is engaged in the limiting groove, so that the first connecting block and the bottom parts can be engaged in the fixing end, thereby completing the assembly of the bearing platform. When the bearing platform needs to be disassembled, the limiting block is raised by the telescopic rod, so that the limiting block returns to the inside of the placement frame, and then the connecting plate is moved to be moved out along the horizontal direction of the fixing end, so that the first connecting block and the bottom parts and the bearing platform are disassembled. In actual construction, this combination method can enable the device to be flexibly assembled to meet different construction needs. At the same time, since its installation and disassembly process is simple and quick, it can greatly improve construction efficiency and reduce construction costs.

[0026] According to the overall structure of the device, the inverted trapezoidal design of the anchor 103 is convenient for insertion into the ground, simplifying the insertion process. When inserting the embedded pile 102, the push block 203 is lifted and lowered in the vertical direction through the telescopic column 201. When the push block 203 descends, the bevel slides along the surface of the linkage block 209, and the linkage block 209 slides outward through the slider 208 and the telescopic spring 207. When the push block 203 falls to the bottom, the two sides of the push block 203 push the linkage block 209 to the maximum position, so that the expansion wing 211 extends out of the embedded pile 102, thereby increasing the contact area with the surrounding soil and preventing soil erosion and Loosen to ensure that the embedded pile 102 remains stable during long-term use. A fixing end 403 is fixed at the bottom of the bearing platform 1. The limit block 407 is engaged in the limit groove 408 through the telescopic rod 406 to complete the assembly of the bearing platform 1. When disassembly is required, the telescopic rod 406 raises the limit block 407 to return the limit block 407 to the inside of the placement frame 405, and then the connecting plate 402 is moved out horizontally along the fixing end 403 for disassembly. This combination method allows the device to be assembled flexibly to meet different construction requirements. The installation and disassembly process is simple and quick, which improves construction efficiency and reduces costs.

[0027] like Figure 1-5 As shown, the first connecting blocks 101 are symmetrically distributed on the top ends of both sides of the bearing platform 1, the anchoring pieces 103 are arranged in an inverted trapezoidal shape, the bottom plate 204 is arranged at the bottom center of the push block 203, the fixed ends 205 are symmetrically distributed on the outside of both sides of the bottom plate 204, the push block 203 forms a lifting structure along the vertical direction of the embedded pile 102 through the telescopic column 201, and 60° bevels are symmetrically opened on both sides of the bottom of the push block 203, and a group of linkage blocks 209 are arranged at one end close to the push block 203 with a bevel that fits the bottom of the push block 203, and one side of the bottom of the push block 203 is tightly fitted with one side of the top of the linkage block 209, and the slide groove 206 is evenly opened along the horizontal direction of the fixed end 205, and the slide groove 206 is arranged in a "convex" shape. The telescopic springs 207 are symmetrically distributed on the inner surface of the slide groove 206, the outer surface of the slider 208 is tightly fitted with the inner surface of the slide groove 206, the slider 208 and the slide groove 206 are slidably connected, and the slider 208 forms a telescopic structure along the horizontal direction of the slide groove 206 through the telescopic spring 207. The inner surface of one side of the expansion wing 211 is fixed to the linkage block 209, and the support bar 210 is tilted and fixed to one side of the bottom of the linkage block 209. The expansion wing 211 forms a telescopic structure with both sides of the embedded pile 102 through the cooperation of the linkage block 209, the slider 208 and the telescopic spring 207. Grooves opposite to the expansion wing 211 are provided on both sides of the embedded pile 102, and the expansion wing 211 is a horizontally placed triangular plate.

[0028] The inverted trapezoidal design of the anchor 103 makes it more convenient to insert it into the ground, and simplifies the insertion process. When the embedded pile 102 is inserted into the ground, the push block 203 is lifted and lowered along the vertical direction of the embedded pile 102 through the telescopic column 201. When the push block 203 descends, the oblique angles on both sides of the bottom slide along the surface of the linkage block 209. At the same time, the linkage block 209 slides outward through the slider 208 and the telescopic spring 207. When the push block 203 falls to the bottom, the two sides of the push block 203 push the linkage block 209 to the maximum position, and the linkage block 209 extends the external expansion wing 211 out of the embedded pile 102, so that the expansion wing 211 can extend out of the embedded pile 102. The embedded pile 102 is more stable when fixed by extending the wing 211 on both sides of the underground. The extension wing 211 not only increases the contact area with the surrounding soil, but also effectively prevents soil erosion and loosening, thereby ensuring that the embedded pile 102 remains stable during long-term use, and enables the bearing platform 1 to maintain stability under different terrains. When the embedded pile 102 needs to be taken out, the telescopic column 201 drives the push block 203 to rise, and at the same time the linkage block 209 loses the squeezing of the push block 203, and the telescopic spring 207 drives the linkage block 209 to retract, and at the same time controls the external expansion wing 211 to retract inward, thereby smoothly taking out the embedded pile 102.

[0029] like Figure 1-5 As shown, the support block 301 forms a lifting structure with the first connecting block 101 through the cooperation of the telescopic block 302 and the lifting rod 303. The lifting rod 303 is evenly distributed along the inside of the telescopic block 302. The embedded pile 102 is connected to the first connecting block 101 through the telescopic block 302, the support block 301 and the second connecting plate 3.

[0030] A stable lifting structure is formed by the support block 301 and the first connecting block 101, and the lifting rod 303 is evenly distributed along the inside of the telescopic block 302, which not only ensures the stability of the lifting rod 303, but also makes the load-bearing platform 1 more evenly stressed during the lifting process. Through the coordinated action of the telescopic block 302 and the lifting rod 303, the load-bearing platform 1 can be height-adjusted, so that the device can meet the needs of different construction scenes and improve the safety and efficiency of construction. Engineers can flexibly adjust the height of the load-bearing platform 1 according to construction needs to ensure the smooth progress of construction.

[0031] like Figure 1-5As shown, the clamping end 403 is fixed to the bottom end of the carrying platform 1, the clamping plate 401 is clamped in the clamping slot 404, the second connecting block 4 is clamped and connected with the connecting plate 402 through the cooperation of the clamping plate 401 and the clamping slot 404, the limiting groove 408 is opened in the clamping end 403, the clamping plate 401 passes through the outside of one side of the clamping end 403 and is connected to the second connecting block 4, the telescopic rods 406 are symmetrically distributed in the placement frame 405, and the outer surface of the limiting block 407 is connected to the placement frame 405 The inner surface of the bracket 408 fits tightly, the limit block 407 forms a lifting structure with the limit slot 408 through the cooperation of the telescopic rod 406 and the placement frame 405, the limit block 407 is snap-connected to the inner wall of the limit slot 408, the connecting plate 402 is snap-connected to the second connecting block 4 through the snap-in slot 404 and the fixing plate 401, and the first connecting block 101 forms a detachable structure with the supporting platform 1 through the fixing plate 401, the fixing end 403, the slot 404, the telescopic rod 406 and the limit block 407.

[0032] By fixing a fixing end 403 at the bottom end of the carrying platform 1, and providing a limiting groove 408 inside the fixing end 403, the limiting groove 408 cooperates with the limiting block 407, and the limiting block 407 is pushed to the bottom through the telescopic rod 406, and the limiting block 407 is engaged in the limiting groove 408, so that the first connecting block 101 and the bottom parts can be engaged in the fixing end 403, thereby completing the assembly of the carrying platform 1. When the carrying platform 1 needs to be disassembled, the limiting block 407 is raised by the telescopic rod 406, so that the limiting block 407 returns to the placement frame 405, and then the connecting plate 402 is moved to be moved out along the horizontal direction of the fixing end 403, so that the first connecting block 101 and the bottom parts and the carrying platform 1 are disassembled. In actual construction, this combination method can enable the device to be flexibly assembled to meet different construction needs. At the same time, due to its simple and quick installation and disassembly process, it can greatly improve construction efficiency and reduce construction costs.

[0033] Working principle: When the device is used, the inverted trapezoidal design of the anchor 103 makes it easier to insert into the ground, simplifying the insertion process. When the embedded pile 102 is inserted into the ground, the push block 203 is lifted and lowered along the vertical direction of the embedded pile 102 through the telescopic column 201. When the push block 203 descends, the bevels on both sides of the bottom slide along the surface of the linkage block 209. At the same time, the linkage block 209 slides outward through the slider 208 and the telescopic spring 207. When the push block 203 falls to the bottom, the two sides of the push block 203 push the linkage block 209 to the maximum position, and the linkage block 209 extends the external expansion wing 211 out of the embedded pile 102, so that the expansion wing 2 11 can extend out of the ground on both sides of the embedded pile 102, and the embedded pile 102 is more stable when fixed by extending the wing 211. The extension of the extended wing 211 not only increases the contact area with the surrounding soil, but also effectively prevents soil erosion and loosening, thereby ensuring that the embedded pile 102 remains stable during long-term use, so that the bearing platform 1 can maintain stability under different terrains. When the embedded pile 102 needs to be taken out, the telescopic column 201 drives the push block 203 to rise, and at the same time the linkage block 209 loses the squeezing of the push block 203, the telescopic spring 207 drives the linkage block 209 to retract, and at the same time controls the external extended wing 211 to retract inward, so that the embedded pile 102 is smoothly taken out.

[0034] Then the support block 301 and the first connection block 101 form a stable lifting structure, and the lifting rods 303 are evenly distributed along the inside of the telescopic block 302, which not only ensures the stability of the lifting rods 303, but also makes the load-bearing platform 1 more evenly stressed during the lifting process. Through the coordinated action of the telescopic block 302 and the lifting rods 303, the load-bearing platform 1 can achieve height adjustment, so that the device can meet the needs of different construction scenes, improve the safety and efficiency of construction, and engineers can flexibly adjust the height of the load-bearing platform 1 according to construction needs to ensure the smooth progress of construction;

[0035] Finally, a fixing end 403 is fixed at the bottom end of the carrying platform 1, and a limiting groove 408 is provided inside the fixing end 403. The limiting groove 408 cooperates with the limiting block 407, and the limiting block 407 is pushed to the bottom by the telescopic rod 406, and the limiting block 407 is engaged in the limiting groove 408, so that the first connecting block 101 and the bottom parts can be engaged in the fixing end 403, thereby completing the assembly of the carrying platform 1. When the carrying platform 1 needs to be disassembled, the limiting block 407 is raised by the telescopic rod 406, so that the limiting block 407 returns to the inside of the placement frame 405, and then the connecting plate 402 is moved to be moved out along the horizontal direction of the fixing end 403, so that the first connecting block 101 and the bottom parts and the carrying platform 1 are disassembled. In actual construction, this combination method can enable the device to be flexibly assembled to meet different construction needs. At the same time, due to its simple and quick installation and disassembly process, it can greatly improve construction efficiency and reduce construction costs.
