Description

Technical Field

[0001] This invention relates to the field of ribbed wall panel technology, specifically a high-strength prefabricated composite ribbed wall panel. Background Technology

[0002] Ribbed slabs refer to reinforced concrete slabs that are reinforced with small beams at the bottom to increase rigidity, reduce span, and decrease thickness before pouring. Ribbed composite wall panels are mainly composed of concrete wall panels and autoclaved aerated concrete blocks. Precast ribbed wall panels have significant advantages in thermal performance compared to ordinary concrete walls. Therefore, current technology often involves the early production of ribbed wall panels (precast panels) to improve installation speed during later construction. However, the overall strength of precast wall panels in current technology is relatively low, especially at the rib bends, making them prone to rib breakage or wall damage under external loads and stresses. Furthermore, due to the poor thermal insulation performance of precast ribbed wall panels, they are often connected to precast insulation boards. However, the connection strength between precast ribbed wall panels and precast insulation boards is currently low, making gaps prone to appear, leading to water seepage and insulation failure. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a high-strength precast composite ribbed wall panel, which solves the problems of low overall strength, low strength at rib bends, and low connection strength between the precast ribbed wall panel and the insulation board in existing technologies.

[0004] To achieve the above objectives, the present invention provides a high-strength precast composite ribbed wall panel, comprising a ribbed mold for forming the ribbed panel and an insulation mold for forming the insulation board. The ribbed mold has a grouting groove for injecting external concrete fluid. The inner wall of the grouting groove has several longitudinal rib grooves for communicating with the grouting groove and forming longitudinal ribs, and several transverse rib grooves for communicating with the grouting groove and forming transverse ribs. The longitudinal rib grooves and transverse rib grooves are arranged in a one-to-one correspondence and cross-connection manner. A main reinforcing mesh composed of several reinforcing bars is provided in the grouting groove. Each longitudinal rib groove contains... There are longitudinal reinforcing bars, and each of the transverse rib grooves is provided with transverse reinforcing bars. Several longitudinal reinforcing bars and several transverse reinforcing bars are arranged in a one-to-one correspondence and staggered arrangement. Several longitudinal reinforcing bars and several transverse reinforcing bars are combined to form a rib mesh. Connecting members for connecting longitudinal reinforcing bars and transverse reinforcing bars are provided at the intersection of longitudinal reinforcing bars and corresponding transverse reinforcing bars. Lifting members for improving the strength at the intersection of longitudinal ribs and transverse ribs are provided in the grouting groove. Linking members for linking with lifting members and providing prestress to the rib mesh are provided on the main reinforcing bar mesh. Fixing members for fixing the insulation board and the dense rib plate are provided in the insulation mold.

[0005] The advantages of adopting the above technical solution are: the operator arranges several longitudinal reinforcing bars and several transverse reinforcing bars in a one-to-one correspondence and staggered manner, and then connects the intersection of each longitudinal reinforcing bar and the adjacent transverse reinforcing bar with connectors, so that several longitudinal reinforcing bars and several transverse reinforcing bars are combined to form a ribbed mesh. Then, a linkage device is used to link with the lifting device and provide prestress to the ribbed mesh. After that, the main reinforcing mesh and the ribbed mesh are placed in the pouring tank, and then concrete fluid is poured to form a densely ribbed slab. In the above technology, the strength of the densely ribbed slab is improved by setting up the ribbed mesh and the main reinforcing mesh, while the lifting device... The design enhances the strength at the intersection of longitudinal and transverse ribs, thereby increasing the strength of the ribs themselves and at rib bends in the ribbed slab. Simultaneously, the linkage and lifting components work in tandem to provide prestress to the ribbed mesh from the main steel mesh. This prestress counteracts the prestress at the ribbed mesh during concrete solidification and shrinkage, further increasing the strength of the solidified concrete and thus improving the overall strength of the ribbed slab. In this technology, after the ribbed slab is poured, a fastener connects it to the insulation board, ensuring the insulation performance of the ribbed slab and improving prefabrication efficiency.

[0006] The present invention further comprises: the lifting member including a first rib disposed on both sides of each longitudinal reinforcing bar and a second rib disposed on both sides of each transverse reinforcing bar, wherein each first rib is connected to its adjacent second rib by a reinforcing bar.

[0007] The advantages of adopting the above technical solution are: the setting of the first and second ribs in the above technology improves the overall strength of the ribbed plate, and also improves the load-bearing capacity of the ribs of the ribbed plate. In addition, there are reinforcing bars connecting the first and second ribs, which further improves the load-bearing capacity and strength of the rib bends. At the same time, the first rib is set parallel to the longitudinal steel bars, and the second rib is set parallel to the longitudinal steel bars, so that the first rib and the adjacent second rib are set perpendicularly and staggered, thereby allowing the reinforcing bars to better fit the rib bends, thereby improving the rib strength.

[0008] The present invention further comprises: a connecting block is provided on each of the longitudinal reinforcing bars; two tension hooks are hooked on each of the first ribs; the two tension hooks are positioned close to their respective adjacent second ribs; an insertion groove is provided at the beginning of the connecting block corresponding to the four adjacent tension hook positions for the ends of the tension hooks to be inserted; a through groove is provided at the end of the connecting block; the insertion groove is connected to the through groove; a rotating shaft is rotatably arranged in the through groove; the ends of the four tension hooks are hinged to the beginning of the rotating shaft; a linkage shaft is rotatably engaged at the end of the rotating shaft; the linkage shaft is coaxial with the rotating shaft; the linkage shaft is threadedly engaged with the opening of the through groove; and the end of the linkage shaft extends out of the through groove.

[0009] The advantages of adopting the above technical solution are as follows: After the longitudinal and transverse reinforcing bars are connected by connectors, the operator rotates the linkage shaft, causing it to move towards the opening of the through groove. The linkage shaft drives the rotating shaft to move towards the through groove, so that the four tension hooks hook onto their respective first ribs and apply force to the first ribs. This causes the first ribs to be subjected to a force in the direction of the linkage shaft, thereby increasing the tension of the first ribs and thus improving their strength in the ribbed plate. At the same time, the ends of the tension hooks are hinged to the outer peripheral wall of the starting end of the rotating shaft, so that the ends of the tension hooks gradually come into contact with the inner peripheral wall of the groove during movement until they abut against each other, allowing the tension hooks to better hook onto the first ribs and apply force. The operator can detachably connect the end of the linkage shaft to the main reinforcing mesh as needed, thereby ensuring that the tension of the first ribs does not loosen.

[0010] The present invention further comprises: a mating shaft rotatably connected to the end of the linkage shaft, the mating shaft being coaxially arranged with the linkage shaft; the linkage component includes a plurality of supporting bars arranged on the main steel mesh, the plurality of supporting bars being arranged perpendicularly to the main steel mesh; the plurality of supporting bars corresponding one-to-one with a plurality of mating shafts and being coaxially arranged; the linkage component further includes a linkage sleeve arranged on each supporting bar; the starting end of the linkage sleeve has a first opening for threaded connection of adjacent mating shafts; and the end of the linkage sleeve has a second opening for threaded connection of the starting ends of adjacent supporting bars.

[0011] The advantages of adopting the above technical solution are: after the linkage shaft is adjusted, the operator connects the mating shaft with the corresponding support bar through the linkage sleeve, thereby realizing the connection between the main steel mesh and the rib mesh, and at the same time, a certain force can be applied to the main steel mesh, thereby realizing the prestressing between the main steel mesh and the rib mesh.

[0012] The present invention further comprises: a fixing bar is provided at each position of the main reinforcing bar mesh corresponding to each supporting bar; the insulation mold is cast into an insulation board; a fixing hole is provided on the insulation board at each position of the fixing bar for the end of the fixing bar to pass through; the fixing component includes a plurality of fixing columns, each of the fixing columns and the plurality of fixing holes are arranged one-to-one; each fixing column is threadedly engaged with its corresponding fixing hole; each fixing column is provided with a limiting hole for the end of the fixing bar to pass through; each end of the fixing bar is threadedly engaged with its corresponding limiting hole; the radial cross section of the fixing hole is trapezoidal; and the shape of the fixing column is adapted to the shape of the fixing hole.

[0013] The advantages of adopting the above technical solution are as follows: After the ribbed plate is made, the fixing bars on the main steel mesh will pass through the ribbed plate. At this time, the operator will stack the insulation board and the ribbed plate, so that the fixing bars on the ribbed plate will be placed into the fixing holes in the insulation board. Then, the operator will screw the fixing column into the fixing hole and connect it with the fixing bar threadedly, so that the fixing bar is stably placed in the fixing hole, thereby improving the connection strength between the insulation board and the ribbed plate. In the above technology, the radial cross section of the fixing hole is set in a trapezoidal shape, and the shape of the fixing column is adapted to the shape of the fixing hole, thereby ensuring that the fixing column will not detach from the fixing hole and cause the fixing bar connection to fail, thus avoiding gaps between the insulation board and the ribbed plate.

[0014] The present invention further comprises: a longitudinal sleeve on each of the longitudinal reinforcing bars, wherein the longitudinal sleeve has a first through hole for adjacent first ribs to pass through; and a transverse sleeve on each of the transverse reinforcing bars, wherein the transverse sleeve has a second through hole for adjacent second ribs to pass through.

[0015] The advantages of adopting the above technical solution are: the connection strength between the longitudinal reinforcement and the first rib is improved by longitudinally connecting the first rib and the longitudinal reinforcement, and the connection strength between the transverse reinforcement and the second rib is improved by transversely connecting the second rib and the transverse reinforcement.

[0016] The present invention further comprises: a first reinforcing ring protruding on both the longitudinal reinforcing bar and the first rib for inserting into the longitudinal rib groove, and a second reinforcing ring protruding on both the transverse reinforcing bar and the second rib for inserting into the longitudinal rib groove, wherein the radial cross-section of the first reinforcing ring and the second reinforcing ring is arranged in a semi-circular arc shape.

[0017] The advantage of adopting the above technical solution is that the setting of the first reinforcing ring and the second reinforcing ring in the above technology can further improve the load-bearing capacity of the ribs of the ribbed plate, thereby improving the overall strength of the ribbed plate.

[0018] The present invention further comprises: the connector includes a connecting sleeve disposed on the longitudinal reinforcing bar, the connecting sleeve having a vertical hole through which the longitudinal reinforcing bar passes, and the connecting sleeve having a horizontal hole through which the transverse reinforcing bar passes.

[0019] The advantage of adopting the above technical solution is that the setting of the connecting sleeve in the above technology ensures a stable connection between the longitudinal and transverse reinforcing bars, thereby improving the connection strength. Attached Figure Description
