Description

Technical Field

[0001] The present invention relates to the field of prefabricated buildings, and in particular to a prefabricated prefabricated structure for civil engineering construction. Background Art

[0002] Prefabricated and assembled buildings refer to a construction method in which some or all of the building components are produced in a component prefabrication factory, then transported to the construction site by appropriate means of transportation, and assembled using reliable installation methods and installation machinery to become a functional building. Compared with on-site construction, prefabricated and assembled construction has the advantages of convenient construction, fast project progress, little impact on the surrounding environment, and easy assurance of the quality of building components.

[0003] Precast beams and slabs are a kind of precast components in which the beams and slabs are a whole and are subjected to force and deformation together. Unlike cast-in-place beams and slabs, precast beams and slabs are prefabricated in the prefabrication yard and then transported to the construction site for assembly. However, due to the excessive weight of precast beams and slabs, they are often assembled manually with the assistance of tower cranes. On the one hand, it is difficult to achieve precise control of the tower crane, resulting in serious deviation in the installation position. On the other hand, manpower is limited, which not only makes it difficult to effectively correct the precast slabs, but also prone to safety accidents. In summary, the current precast beam and slab assembly efficiency is extremely low, which seriously delays the overall construction efficiency of prefabricated buildings.

[0004] Therefore, it is necessary to provide a new prefabricated and assembled structure for building civil engineering construction to solve the above technical problems. Summary of the invention

Therefore, the features defined as "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0036] In the specific implementation process, Figure 1-Figure 7 As shown, the prefabricated assembled structure for building civil engineering construction includes a prefabricated column 1, a plurality of prefabricated top plates 2, and an assembled load-bearing wall structure, the assembled load-bearing wall structure is used to support the prefabricated column 1 and the plurality of prefabricated top plates 2, a plurality of positioning columns 3 are equidistantly arranged on the bottom edge of the prefabricated column 1, an annular through hole 4 matching the positioning column 3 is reserved at one end of the plurality of prefabricated top plates 2, an annular through hole 4 matching the positioning column 3 is reserved at one end of the plurality of prefabricated top plates 2, and can be inserted into the plurality of positioning columns 3 at the bottom edge of the prefabricated column 1, and a prefabricated beam plate 5 is arranged between two adjacent prefabricated top plates 2, a protective plate 30 is arranged on the top of the plurality of prefabricated beam plates 5, and a ring structure is formed between the plurality of protective plates 30;

[0037] One end of multiple precast beams 5 is fitted with the edge of the precast column 1, and the other ends of multiple precast beams 5 are all clamped with arc plates 6. Multiple arc plates 6 are spliced ​​together to form a circular ring shape. The inner walls of multiple arc plates 6 are provided with two opposite connecting grooves 7. Two adjacent connecting grooves 7 are provided with anchor end plates 8 and prestressed tendons 9. Both sides of one end of the precast beam 5 are respectively provided with stretching clamping blocks 10. One end of the stretching clamping block 10 is provided with a positioning groove 11 matching the anchor end plate 8 and the prestressed tendon 9. The positioning groove 11 at one end of the stretching clamping block 10 is clamped on the anchor end plate 8 and the prestressed tendon 9. The clamping design of the precast beam 5 and the arc plate 6 further enhances the stability of the entire roof structure. The application of the anchor end plate 8 and the prestressed tendon 9 provides additional tensile strength, making the structure more stable. It should be noted that before the precast beam 5 is clamped with the arc plate, multiple arc plates need to be spliced ​​together to form a circular ring.

[0038] In a specific implementation process, refer to Figure 4As shown, the assembled load-bearing wall structure includes a plurality of prefabricated load-bearing columns 12, and the plurality of prefabricated load-bearing columns 12 are respectively connected to the bottom of the plurality of curved plates 6 through adjustable columns, and the adjustable columns are used to adjust the spacing between the plurality of prefabricated load-bearing columns 12 and the plurality of curved plates 6, and an assembly bottom plate 13 is provided between two adjacent prefabricated load-bearing columns 12, and the assembly bottom plate 13 is connected to the construction foundation;

[0039] It should be noted that the reference Figure 3 as well as Figure 7 As shown, both sides of the precast beam 5 are provided with slide grooves 26, and two stretch-type snap-fitting blocks 10 are respectively slidably installed inside the two slide grooves 26 provided on the precast beam 5. Elastic springs 27 are provided inside the two slide grooves 26. The two ends of the two elastic springs 27 are respectively welded to the inner walls of the two slide grooves 26 and one end of the two stretch-type snap-fitting blocks 10. By sliding the stretch-type snap-fitting block 10, the positioning groove 11 at one end thereof can be snap-fitted to the anchor end plate 8 and the prestressed tendon 9. When the stretch-type snap-fitting block 10 is separated from the connecting through groove 7 of the arc plate, the elastic spring 27 is in a compressed state.

[0040] It should be further explained that the reference Figure 4 as well as Figure 5 As shown, the adjustable column includes a fixed anchor rod 28 and an adjusting sleeve 29. The fixed anchor rod 28 is fixedly installed at the bottom of the curved plate 6, and the adjusting sleeve 29 is rotatably installed at the top of the prefabricated load-bearing column 12. The adjusting sleeve 29 is threadedly connected to one end of the fixed anchor rod 28. By twisting the adjusting sleeve 29, the overall length between the fixed anchor rod 28 can be adjusted, and then the spacing between the prefabricated load-bearing column 12 and the curved plate 6 can be adjusted, which can ensure that each component meets the precise position requirements during installation. This not only improves the overall accuracy of the building, but also reduces the rework caused by on-site measurement errors. The design of the adjustable column allows the distance between components to be flexibly adjusted according to actual conditions during the construction process, which provides a possibility for coping with uneven foundation settlement or other unforeseen changes.

[0041] Embodiment 2

[0042] In a specific implementation process, refer to Figure 4 , Figure 5 as well as Figure 8 As shown, a transverse anchor cable shear-resistant connection assembly is also provided between two adjacent prefabricated bearing columns 12, wherein the transverse anchor cable shear-resistant connection assembly includes two relative positioning screws 15, two relative connecting shafts 16 and two relative connecting sleeves 17, the two positioning screws 15 are respectively fixedly installed on one side of the two prefabricated bearing columns 12, the two positioning screws 15 are respectively threadedly connected to the two connecting shafts 16, the two connecting sleeves 17 are respectively threadedly connected to one end of the two connecting shafts 16, and the inner sides of the two connecting sleeves 17 are provided with anti-pull grooves 18;

[0043] The end of the anti-pull groove 18 away from the connecting shaft 16 is inclined toward the end of the connecting sleeve 17. A clamping block with a retractable end is provided in the anti-pull groove 18. Two independent clamps 20 are provided at one end of the clamping block. A connecting groove 21 for the anchor cable 22 to pass through is opened in the middle of the two clamps 20. The outer surfaces of the two clamps 20 respectively match the inclined surfaces of the anti-pull groove 18, and the two clamps 20 can be retracted against each other.

[0044] It should be noted that the clamping block includes an anchor plate 23 and two opposing compression springs 24. The outer side of the anchor plate 23 is in contact with the end of the connecting shaft 16. One end of the two compression springs 24 is welded to one end of the two clamps 20 respectively, and the other end of the two compression springs 24 is welded to the inner side of the anchor plate 23 respectively.

[0045] It should be further explained that a groove 25 for fixing the end of the anchor cable 22 is also provided on the inner side of the anchor plate 23. The anti-tension groove 18, the connecting groove 21 and the groove 25 are collinear. The design of the anti-tension groove 18, the connecting groove 21 and the groove 25 as collinear ensures a straight line transmission path for the anchor cable 22 when subjected to force, avoids the local stress concentration phenomenon caused by angle deviation, and prolongs the service life of the component.

[0046] When the transverse anchor cable shear connection assembly is in use, the anchor cable 22 is passed through the tensile groove 18 and the connecting groove 21 in turn and extended into the groove 25. The connecting shaft 16 is rotated to make it threadedly matched with the connecting sleeve 17, and the connecting shaft 16 is screwed into the connecting sleeve 17. The other end of the connecting shaft 16 is screwed into the positioning screw 15, and the screw-in distance is adjusted as needed. The connecting shaft 16 will squeeze the anchor plate 23 to move inside the tensile groove 18 while being screwed in. With the compression of the compression spring 24, the clamp 20 is attached to the inclined surface of the tensile groove 18. At this time, the two clamps 20 are retracted to each other and clamp the anchor cable 22. Since the end of the tensile groove 18 away from the connecting shaft 16 is inclined toward the end of the connecting sleeve 17, when the anchor cable 22 is pulled outward, the two clamps 20 are retracted inward along the inclined surface of the tensile groove 18, which will increase The squeezing force on the anchor cable 22 is applied, and one end of the anchor cable 22 is against the groove 25, so that the anchor cable 22 is not easy to loosen. When disassembling, the connecting sleeve 17 is rotated to separate it from the connecting shaft 16. Then, the anchor plate 23 can be pulled out from one end of the connecting sleeve 17 due to the loss of squeezing of the connecting shaft 16. As the two clamps 20 move away from the anti-tension groove 18, the two clamps 20 separate from each other, and the anchor cable 22 loses its clamping force and can be taken out. The design of the anti-tension groove 18 allows the clamp block to be retractable at the end, and the clamps 20 can be retracted or unfolded as needed. This feature allows the connection component to automatically adjust under different stress states and adapt to various complex load conditions, thereby improving the adaptability of the system. At the same time, the application of elastic parts provides the necessary pre-tightening force for the clamp block, ensuring that the anchor cable 22 will not slide or fall off easily when subjected to external forces.

[0047] In addition, the assembly base plate 13 and the curved plate 6 are connected by a vertical anchor cable 22 shear-resistant connection assembly;

[0048] It should be noted that the structure of the vertical anchor cable shear connection assembly 14 is the same as that of the transverse anchor cable 22 shear connection assembly, the difference being that in the vertical anchor cable shear connection assembly 14, two positioning screws 15 are respectively fixed to the assembly base plate 13 and the inner side of the arc plate.

[0049] Embodiment 3

[0050] In a specific implementation process, refer to Figure 1 , Figure 2 as well as Figure 4 As shown, a concrete wall panel layer 19 is further provided between the arc-shaped plate 6 and the assembly bottom plate 13 to improve the fixing effect, and the anchor cable 22 is located on the inner side of the concrete wall panel layer 19 .

[0051] The working principle provided by the present invention is as follows: when the structure is used, the annular through holes 4 reserved at one end of the plurality of prefabricated top plates 2 and matching with the positioning columns 3 are first inserted into the plurality of positioning columns 3 at the bottom edge of the prefabricated platform column 1, and the prefabricated beam plates 5 are placed between two adjacent prefabricated top plates 2, so that one end of the plurality of prefabricated beam plates 5 is in contact with the edge of the prefabricated platform column 1, and the other end of the plurality of prefabricated beam plates 5 is engaged with the arc plate 6. It should be noted that before the prefabricated beam plates 5 are engaged with the arc plate, the plurality of arc plates need to be spliced ​​together to form a circular ring;

[0052] By screwing the adjusting sleeve 29, the overall length between the fixed anchor rod 28 can be adjusted, and then the spacing between the prefabricated bearing column 12 and the curved plate 6 can be adjusted to complete the assembly between the curved plate and the prefabricated bearing column 12. The transverse anchor shear connection assembly and the vertical anchor shear connection assembly 14 are respectively fixed between the two prefabricated bearing columns 12 and between the curved plate and the assembly base plate 13 to reinforce the structure, and the assembly base plate 13 can be fixedly connected to the construction foundation. In the transverse anchor shear connection assembly and the vertical anchor shear connection assembly 14, the anchor cable 22 is sequentially passed through the anti-tension groove 18 and the connecting groove 21 and extended into the groove 25. The connecting shaft 16 is rotated to make it threadedly matched with the connecting sleeve 17, and the connecting shaft 16 is screwed into the connecting The connecting sleeve 17 is connected, and the connecting shaft 16 will squeeze the anchor plate 23 to move inside the tensile groove 18 when it is screwed in. With the squeezing of the compression spring 24, the clamp 20 is fitted on the inclined surface of the tensile groove 18. At this time, the two clamps 20 are retracted to each other and clamp the anchor cable 22. Since the end of the tensile groove 18 away from the connecting shaft 16 is inclined toward the end of the connecting sleeve 17, when the anchor cable 22 is pulled outward, the two clamps 20 are retracted inward along the inclined surface of the tensile groove 18, which will increase the squeezing force on the anchor cable 22. One end of the anchor cable 22 is against the groove 25, so that the anchor cable 22 is not easy to loosen. Finally, the concrete wall panel layer 19 is fixed between the arc plate 6 and the assembly base plate 13 with bolts, and the anchor cable 22 is located on the inner side of the concrete wall panel layer 19.
