Description

A precast formwork structure for keel piers Technical Field

[0001] This utility model relates to the field of keel pier casting template technology, and more specifically, to a keel pier precast template structure. Background Technology

[0002] As the bottom support structure in the process of shipbuilding or maintenance in large port dock projects, the keel pier needs to be formed in one go in terms of its external processing dimensions. Currently, keel pier templates are used and concrete is poured into them to prepare the keel pier.

[0003] Previously, the casting formwork for the keel pier was assembled from multiple pieces of wood. That is, the wooden blocks were stacked according to the size requirements of the keel pier. During the stacking process, the dimensions of each part were measured and adjusted to meet the design requirements.

[0004] Currently, when assembling the wooden blocks of the keel pier casting formwork, sawdust or wire is typically used for reinforcement and positioning. However, the connection between the wooden blocks is not tight and stable enough, which easily leads to deviations in the size and shape of the keel pier after casting. Furthermore, the wooden formwork is prone to deformation under the vibration after the concrete is poured, further causing deviations in the keel pier's dimensions. In other words, the wooden formwork is prone to misalignment or deviation during the casting process. In summary, the current keel pier casting formwork has the above-mentioned problems that urgently need to be solved. Summary of the Invention

[0005] The purpose of this utility model is to solve the problems mentioned in the background art, and then to propose a keel pier prefabricated template structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A precast formwork structure for a keel pier includes a first steel formwork, a second steel formwork, a double fixing assembly, pre-drilled holes, shaped steel, mounting holes, fastening components, wooden blocks, and round pipes.

[0008] The two ends of the two facing first steel formworks are respectively connected to the facing second steel formworks through double fixing components, and the first steel formworks and the second steel formworks form a keel pier casting cavity with open upper and lower ends.

[0009] The reserved holes are symmetrically opened on the first steel template, and a shaped steel piece with a matching size is fitted into the two reserved holes on the two first steel templates. The shaped steel piece has a through mounting hole.

[0010] The fastening components are symmetrically arranged inside the mounting holes and extend to the outside of the mounting holes;

[0011] The wooden blocks are fixed on both sides of the shaped steel, and the wooden blocks are firmly fixed to the surface of the first steel formwork by fastening components and round tubes so that the position of the shaped steel is limited during the concrete pouring process.

[0012] Furthermore, both the first and second steel molds include steel plates and angle steels, with spot welding between the steel plates and angle steels and oil applied to the inner surface of the steel plates.

[0013] Furthermore, both the first and second steel molds are provided with reinforcing steel.

[0014] Furthermore, the dual fixing assembly includes a large fastening bolt and a small fastening bolt, and the first steel template and the second steel template are fastened at multiple points, both internally and externally, by the large fastening bolt and the small fastening bolt.

[0015] Furthermore, the gap between the shaped steel and the reserved hole is sealed with sealant.

[0016] Furthermore, the fastening assembly includes a fixing plate, a long screw, a nut, and a fastening plate. The fixing plates are symmetrically fixed in the mounting holes. The two fixing plates are respectively fixed with long screws extending to the outside of the mounting holes. Nuts are threaded onto the long screws. The nuts are fixed to the fastening plates. The fastening plates have through holes that allow the long screws to pass through. The fastening plates, together with the round tube, firmly fix the wooden block to the first steel template.

[0017] Furthermore, a plastic film is laid at the bottom of the casting cavity of the keel pier.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Compared to existing technologies, the first and second steel formwork in this application adopt a combination structure of steel plates and angle steel.

At the same time, the double fixing components provide multi-point internal and external connection and fastening during the formwork assembly process, ensuring that the formwork joints are dense and stable. This effectively avoids the deformation of the pouring formwork caused by vibration during concrete pouring, which would lead to substandard keel pier pouring quality. Meanwhile, the shaped steel does not move during concrete pouring, ensuring that the external dimensions of the keel pier after pouring meet the design requirements. The performance of the keel pier pouring formwork is significantly improved. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0027] As shown in Figures 1 to 4, a precast formwork structure for a keel pier includes a first steel formwork 1, a second steel formwork 2, a double fixing assembly, reserved holes (not numbered in the figures), shaped steel 4, mounting holes 5, fastening components, wooden blocks 6, and round pipes 7.

[0028] The two ends of the two opposing first steel molds 1 are respectively connected to the opposing second steel molds 2 by double fixing components, and the first steel molds 1 and the second steel molds 2 form a keel pier casting cavity with open upper and lower ends.

[0029] The reserved holes are symmetrically opened on the first steel template 1, and a shaped steel 4 with a matching size is fitted in the two reserved holes on the two first steel templates 1. The shaped steel 4 has a through mounting hole 5.

[0030] The fastening components are symmetrically arranged inside the mounting hole 5 and extend to the outside of the mounting hole 5;

[0031] Wooden blocks 6 are fixed on both sides of the shaped steel 4, and the wooden blocks 6 are firmly fixed to the surface of the first steel formwork 1 by fastening components and round tubes 7 so that the position of the shaped steel 4 is limited during the concrete pouring process.

[0032] The specific implementation of this utility model embodiment is shown in Figures 1 to 4. The fastening assembly includes a fixing plate 9, a long screw 10, a nut 11, and a fastening plate 12. The fixing plates 9 are symmetrically fixed in the mounting holes 5. The two fixing plates 9 are respectively fixed with long screws 10 extending to the outside of the mounting holes 5. Nuts 11 are threaded onto the long screws 10. The nuts 11 are fixed to the fastening plates 12. The fastening plates 12 are provided with through holes (not shown in the figure) that allow the long screws 10 to pass through. The fastening plates 12, together with the round tube 7, firmly fix the wooden block 6 on the first steel template 1.

[0033] The specific implementation of the present invention is shown in Figures 1 to 3. The dual fixing component includes a large fastening bolt 3 and a small fastening bolt 31. The first steel mold plate 1 and the second steel mold plate 2 are fastened at multiple points inside and outside by the large fastening bolt 3 and the small fastening bolt 31 so that the first steel mold plate 1 and the second steel mold plate 2 are tightly and firmly connected.

[0034] In a further refinement of the embodiment of this utility model, both the first steel template 1 and the second steel template 2 include steel plates and angle steel. The steel plates and angle steel are spot welded together, and the inner surface of the steel plates is brushed with oil. Brushing with oil can ensure that the steel template is easy to remove and separate after pouring and ensure the smoothness of the keel pier surface.

[0035] To further improve the strength of the template, the above-described embodiment is further optimized by providing reinforcing steel 8 on both the first steel template 1 and the second steel template 2.

[0036] To prevent concrete from flowing out of the gap between the shaped steel 4 and the reserved hole during the subsequent pouring process, the above embodiment is further refined by sealing the gap between the shaped steel 4 and the reserved hole with sealant.

[0037] To prevent adhesion at the bottom of the keel pier after pouring, a further optimization of the above embodiment is to cover the bottom of the keel pier pouring cavity with a plastic film.

[0038] The working process of this utility model:

[0039] Based on the overall structural layout requirements of the keel pier formwork, the first steel formwork 1 and the second steel formwork 2 are first fabricated and assembled. The steel formwork has high strength. The first steel formwork 1 and the second steel formwork 2 are fastened together by double fixing components at multiple points inside and outside to ensure a tight and stable connection between the first steel formwork 1 and the second steel formwork 2. The overall frame support is achieved by angle steel, and the angle steel and the steel plate are connected by spot welding to ensure that the overall frame structure does not deform. In addition, reinforcing steel 8 is added to the first steel formwork 1 and the second steel formwork 2 respectively for strength reinforcement to further prevent deformation.

[0040] Secondly, the shaped steel 4 is made on-site from steel plates. The shaped steel 4 is rectangular in shape. After the first steel formwork 1 and the second steel formwork 2 are firmly assembled and installed, the shaped steel 4 passes through the two pre-drilled holes on the first steel formwork 1. After the shaped steel 4 passes through, wooden blocks 6 are fixed on both sides. Then, the wooden blocks 6 are firmly fixed on the first steel formwork 1 by fastening components and round pipes 7 to prevent the shaped steel 4 from moving during subsequent concrete pouring. After the position of the shaped steel 4 is fixed, sealant is applied to the gap between the pre-drilled hole and the shaped steel to prevent subsequent concrete overflow. After the above process is completed, the keel pier can be poured and vibrated to form the pier.

[0041] In summary, the first steel formwork 1 and the second steel formwork 2 in this application adopt a combined structure of steel plates and angle steel. The angle steel supports the overall structure, and the steel plates are filled within the frame structure formed by the angle steel, resulting in high overall strength of the formwork and resistance to deformation. Simultaneously, the double fixing components provide multi-point internal and external connection and tightening during the formwork assembly process, ensuring that the formwork joints are dense and stable. This effectively prevents deformation of the casting formwork caused by vibration during concrete pouring, which could lead to substandard casting quality of the keel pier. Furthermore, the shaped steel 4 does not move during concrete pouring, ensuring that the dimensions of the keel pier after pouring meet design requirements. The overall performance of the keel pier casting formwork is significantly improved.
