[0002] Keel-coated plastic formwork is a new type of building formwork. It uses square steel keels as the internal support skeleton to provide stable structural strength and load-bearing capacity. The square steel keels can effectively improve the plastic formwork's ability to resist lateral forces and deformation. The square steel keels and plastic formwork work together to ensure that the keel-coated plastic formwork and support system can maintain a stable and reliable working state during the concrete pouring process, thus ensuring the quality of building structure formation and construction safety.

[0003] However, existing quick-release support systems for lightweight, high-strength square steel keel plastic-coated formwork often have the following problems when in use:

[0004] 1. The supporting structure of the keel plastic-coated formwork, namely the square steel keel inside, is difficult to install and disassemble quickly with the formwork during construction. In other words, the disassembly and assembly rate of the supporting structure in the keel plastic-coated formwork is low, making it inconvenient to adjust the overall supporting force and stability of the keel plastic-coated formwork.

[0005] 2. In addition, the splicing and installation of multiple keel plastic-coated formwork usually adopts welding or riveting methods. However, during the splicing and installation process, it is not convenient to quickly and accurately position and fix the splicing position of two adjacent keel plastic-coated formwork, resulting in low overall splicing and installation efficiency of keel plastic-coated formwork.

An insertion shaft is fixedly connected to the outer wall of the straight plate. An insertion through hole is opened on the insertion fixing frame. The insertion shaft is matched with the insertion through hole.

[0014] Preferably, the quick-assembly assembly includes two lifting slide rods fixedly connected to the lower end face of the coated template. A lifting plate is slidably connected to the outer wall of the two lifting slide rods. Two second-positioning shafts are fixedly connected to the upper end face of the lifting plate. One side wall of the coated template has a mating groove, and the other side wall has a splicing protrusion. The splicing protrusion and the mating groove are symmetrically arranged. Second-positioning holes are provided at the mating groove and on the splicing protrusion on the lower end face of the coated template. The second-positioning shafts are matched with the second-positioning holes. Several splicing fixing components are fixedly connected to the lower end face of the coated template, and these components are used to lock and fix adjacent coated templates.

[0015] Preferably, the splicing and fixing component includes a splicing and fixing bracket fixedly connected to the lower end face of the plastic-coated template. A threaded sleeve is fixedly connected to the end of the splicing and fixing bracket away from the plastic-coated template. A locking bolt is threadedly connected to the inner side of the threaded sleeve. A locking thread groove is opened on the lower end face of the plastic-coated template. The locking bolt is matched with the locking thread groove.

[0016] Preferably, a linear guide rail is fixedly connected to the lower end face of the plastic-coated template, and a roller frame is fixedly connected to the upper end face of each of the two opposing sliders.

By utilizing the corresponding matching of the square steel keel with the snap-fit ​​groove, as well as the first positioning shaft and the first positioning insertion hole, the initial positioning and fixing of the square steel keel and the plastic-coated template can be quickly completed. Then, by rotating the bidirectional screw, the two opposing sliders are driven to move in opposite directions, so that the two insertion shafts can move in opposite directions synchronously and respectively enter the insertion through holes on the two insertion fixing brackets, so that the two square steel keels can be inserted and fixed synchronously at the same time. When the square steel keel is disassembled, by rotating the bidirectional screw in the opposite direction, the two insertion shafts can move towards each other, thereby realizing the disassembly operation of the square steel keel relative to the plastic-coated template. This can improve the disassembly and assembly speed of the support structure in the keel plastic-coated template and facilitate the adjustment of the overall support force and stability of the keel plastic-coated template.

[0026] 2. This utility model is equipped with a quick-assembly component.

After the two adjacent plastic-coated templates are spliced ​​and positioned, the locking bolt on one of the plastic-coated templates corresponds exactly to the locking thread groove on the lower end face of the other plastic-coated template. By tightening the locking bolt, the two adjacent plastic-coated templates can be fully locked and fixed, realizing the quick splicing and installation of the two adjacent plastic-coated templates. This can effectively improve the overall splicing and installation efficiency of the keel plastic-coated template. Attached Figure Description

[0036] The following embodiments are for illustrative purposes only and are not intended to limit the scope of this invention.

[0037] like Figures 2-8As shown, a lightweight, high-strength square steel keel coated formwork quick-release support system includes: a coated formwork 1, two square steel keels 2, and a quick-release support assembly. The coated formwork 1 is made of lightweight carbon fiber reinforced plastic. Both square steel keels 2 are rectangular hollow structures. The quick-release support assembly includes two No. 1 positioning shafts 3 fixedly connected to the upper end face of the square steel keels 2. Two snap-fit ​​grooves 4 are opened on the lower end face of the coated formwork 1. The two square steel keels 2 are respectively matched with the two snap-fit ​​grooves 4. A No. 1 positioning insertion hole 5 is opened on the bottom surface of the snap-fit ​​groove 4. The No. 1 positioning shaft 3 is matched with the No. 1 positioning insertion hole 5. Insertion fixing brackets 6 are fixedly connected to the inner side of both square steel keels 2. An insertion driving component is fixedly connected to the lower end face of the coated formwork 1. The insertion driving component is used to complete the insertion and fixing of the insertion fixing brackets 6. The insertion driving component includes components fixedly connected to... A rotating bracket 7 is located on the lower end face of the plastic-coated template 1. A bidirectional screw 8 is rotatably connected to the rotating bracket 7. A disassembly knob 26 is fixedly connected to the middle position of the outer wall of the bidirectional screw 8. Several silicone anti-slip strips 27 are fixedly connected to the outer peripheral wall of the disassembly knob 26. Two opposing sliders 9 are threadedly connected to the bidirectional screw 8. A linear guide rail 23 is fixedly connected to the lower end face of the plastic-coated template 1. A roller frame 24 is fixedly connected to the upper end face of the two opposing sliders 9. A roller 25 is rotatably connected to the roller frame 24. The roller 25 is matched with the linear guide rail 23. Several guide rods 10 are fixedly connected to the outer wall of the two opposing sliders 9. A straight plate 11 is fixedly connected to the end of the guide rods 10 away from the opposing sliders 9. A plug-in shaft 12 is fixedly connected to the outer wall of the straight plate 11. A plug-in through hole 29 is opened on the plug-in fixing bracket 6. The plug-in shaft 12 is matched with the plug-in through hole 29.

[0038] The square steel keel 2 is inserted into the snap-fit ​​groove 4 on the lower end face of the plastic-coated template 1. At this time, the first positioning shaft 3 is simultaneously inserted into the first positioning insertion hole 5 to quickly complete the initial positioning and fixing of the square steel keel 2 and the plastic-coated template 1. Then, by rotating the disassembly knob 26, the bidirectional screw 8 is driven to rotate, so that the two opposing sliders 9 on the bidirectional screw 8 begin to move in opposite directions. Then, the two opposing sliders 9 begin to drive the two insertion shafts 12 to move synchronously in opposite directions through several guide rods 10, and respectively enter the insertion through holes 29 on the two insertion fixing brackets 6, so that the two square steel keels 2 can be inserted and fixed synchronously at the same time. When the square steel keel 2 is disassembled, the bidirectional screw 8 is rotated in the opposite direction, so that the two insertion shafts 12 move towards each other, so that the insertion shafts 12 no longer engage with the insertion fixing brackets 6. This allows the square steel keel 2 to be disassembled relative to the plastic-coated template 1, thereby improving the disassembly and assembly speed of the support structure in the keel plastic-coated template and facilitating the adjustment of the overall support force and stability of the keel plastic-coated template.

[0039] like Figures 1-3 , Figure 6 and Figure 7As shown, a quick-connect assembly is fixedly connected to the lower end face of the plastic-coated template 1. The quick-connect assembly is used to quickly connect and install two adjacent plastic-coated templates 1. The quick-connect assembly includes two lifting slide rods 13 fixedly connected to the lower end face of the plastic-coated template 1. A lifting plate 14 is slidably connected to the outer wall of the two lifting slide rods 13. A pressure spring 28 is fitted on the outer wall of the lifting slide rod 13. The upper and lower ends of the pressure spring 28 are fixedly connected to the lower end face of the lifting plate 14 and the lower end of the lifting slide rod 13, respectively. Two second positioning shafts 15 are fixedly connected to the upper end face of the lifting plate 14. A mating groove 16 is opened on one side wall of the plastic-coated template 1, and a splicing protrusion 17 is fixedly connected to the other side wall of the plastic-coated template 1. The splicing protrusion 17 and the mating groove 16 are connected to each other. The structure is symmetrical. The lower end face of the plastic-coated template 1 is provided with a second positioning hole 18 at the docking groove 16 and on the splicing protrusion 17. The second positioning shaft 15 is matched with the second positioning hole 18. Several splicing fixing components are fixedly connected to the lower end face of the plastic-coated template 1. The splicing fixing components are used to lock and fix two adjacent plastic-coated templates 1. The splicing fixing components include a splicing fixing bracket 19 fixedly connected to the lower end face of the plastic-coated template 1. A threaded sleeve 20 is fixedly connected to the end of the splicing fixing bracket 19 away from the plastic-coated template 1. A locking bolt 21 is threadedly connected to the inner side of the threaded sleeve 20. A locking thread groove 22 is provided on the lower end face of the plastic-coated template 1. The locking bolt 21 is matched with the locking thread groove 22.

[0040] By pulling the lifting plate 14 downward, the pressure spring 28 is gradually compressed and accumulates a certain elastic potential energy. At this time, the two adjacent plastic-coated templates 1 are spliced, that is, the splicing protrusion 17 on one plastic-coated template 1 is connected to the docking groove 16 on the other plastic-coated template 1. Then, no more pulling force is applied to the lifting plate 14. The elastic potential energy of the pressure spring 28 is used to push the lifting plate 14 to rise automatically, so that the second positioning shaft 15 on the lifting plate 14 can be connected to the second positioning insertion hole 18 on the plastic-coated template 1 and the splicing protrusion 17 in sequence, so as to quickly and accurately splice and position the two adjacent plastic-coated templates 1. After the two adjacent plastic-coated templates 1 are spliced ​​and positioned, the locking bolt 21 on one plastic-coated template 1 corresponds exactly to the locking thread groove 22 on the lower end face of the other plastic-coated template 1. At this time, by tightening the locking bolt 21, the two adjacent plastic-coated templates 1 can be fully locked and fixed, thereby realizing the rapid splicing and installation of the two adjacent plastic-coated templates 1, effectively improving the overall splicing and installation efficiency of the keel plastic-coated template.

[0041] like Figure 1 As shown, an installation method for a quick-release support system for lightweight high-strength square steel keel plastic-coated formwork specifically includes the following steps:

[0042] S1. Construction preparation;

[0043] S2, Installation of square steel keel 2 and plastic-coated template 1;

[0044] S3. Splicing and laying of plastic-coated template 1;

[0045] S4. Concrete pouring and curing.

[0046] The working principle of this utility model is as follows:

[0047] 1. In use, insert the square steel keel 2 into the snap-fit ​​groove 4 on the lower end face of the plastic-coated template 1. At this time, the first positioning shaft 3 is simultaneously inserted into the first positioning insertion hole 5 to quickly complete the initial positioning and fixing of the square steel keel 2 and the plastic-coated template 1. Then, by rotating the disassembly knob 26, the bidirectional screw 8 is driven to rotate, so that the two opposing sliders 9 on the bidirectional screw 8 begin to move in opposite directions. This causes the two opposing sliders 9 to drive the two insertion shafts 12 to move synchronously in opposite directions through several guide rods 10, and respectively connect to the groove. The two insertion through holes 29 on the two insertion fixing brackets 6 are used to simultaneously insert and fix the two square steel keels 2. When the square steel keel 2 is disassembled, the two-way screw 8 is rotated in the opposite direction to make the two insertion shafts 12 move towards each other, so that the insertion shafts 12 no longer engage with the insertion fixing brackets 6. This allows the square steel keel 2 to be disassembled relative to the plastic-coated template 1, thereby improving the disassembly and assembly speed of the support structure in the plastic-coated template and facilitating the adjustment of the overall support force and stability of the plastic-coated template.

[0048] 2. During the splicing and installation of the keel-coated template, by pulling the lifting plate 14 downward, the pressure spring 28 is gradually compressed and accumulates a certain elastic potential energy. At this time, two adjacent coated templates 1 are spliced, that is, the splicing protrusion 17 on one coated template 1 is connected to the mating groove 16 on the other coated template 1. Then, no more pulling force is applied to the lifting plate 14, and the elastic potential energy of the pressure spring 28 is used to push the lifting plate 14 to rise automatically, so that the second positioning shaft 15 on the lifting plate 14 can be connected to the coated template 1 and the other template in sequence. The second positioning hole 18 on the splicing protrusion 17 is used to quickly and accurately splice and position two adjacent plastic-coated templates 1. After the two adjacent plastic-coated templates 1 are spliced ​​and positioned, the locking bolt 21 on one of the plastic-coated templates 1 corresponds exactly to the locking thread groove 22 on the lower end face of the other plastic-coated template 1. At this time, by tightening the locking bolt 21, the two adjacent plastic-coated templates 1 can be fully locked and fixed, thereby realizing the rapid splicing and installation of the two adjacent plastic-coated templates 1 and effectively improving the overall splicing and installation efficiency of the keel plastic-coated template.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
