[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1-8 A quick-assembly template for cylindrical structures includes a steel template 1 and a snap-fit ​​assembly 2 disposed on the side of the steel template 1. The steel template 1 is arc-shaped, and multiple steel templates 1 are joined end to end to form a cylinder. The surface of the steel template 1 is provided with reinforcing ribs. The snap-fit ​​assembly 2 includes multiple snap blocks 201 fixed on the side of the steel template 1 and multiple insertion holes 202 opened on the other side of the steel template 1. The multiple snap blocks 201 correspond to the multiple insertion holes 202. The snap blocks 201 are L-shaped, and the insertion holes 202 are divided into an upper half and a lower half. The lower half insertion hole 202 is a trapezoidal hole that facilitates the snap blocks 201 to snap into the upper half insertion hole 202. The surface of the steel formwork 1 is provided with a positioning component 3 for positioning adjacent steel formwork 1s. The positioning component 3 includes multiple positioning pins 301 fixed on the lower surface of the steel formwork 1 and multiple positioning holes 302 opened on the upper surface of the steel formwork 1. Both the positioning pins 301 and the positioning holes 302 are conical.

[0029] Understandably, multiple curved steel templates 1 are connected sequentially to form a cylindrical template. During template assembly, the steel template 1 is hung on the surface of the clip 201 of the adjacent steel template 1 through the insertion hole 202. After the steel template 1 is pressed down, the positioning pin 301 is inserted into the positioning hole 302 to position and connect the upper and lower steel templates 1. At the same time, the clip 201 is engaged with the upper half of the insertion hole 202, thereby limiting the two adjacent steel templates 1 and preventing the steel templates 1 from moving freely before the complete assembly, thus achieving the purpose of rapid assembly.

[0030] Specifically, multiple limiting rings 4 are fixed on the surface of the steel template 1. Each limiting ring 4 is a U-shape with an opening at the top. Multiple steel templates 1 at the same height are fastened by fastening ropes 5. The two ends of the fastening ropes 5 are connected by fastening components 6. The fastening components 6 include a tube body 601 fixed to one end of the fastening rope 5 and a threaded rod 603 fixed to the other end of the fastening rope 5. A threaded cap 602 is rotatably attached to the other end of the tube body 601.

[0031] It is understandable that by setting the fastening rope 5 and the fastening component 6, the fastening rope 5 is passed through multiple limiting rings 4, and then the threaded rod 603 is connected to the threaded cap 602. The threaded rod 603 is inserted into the tube body 601 through the threaded cap 602, thereby binding the fastening rope 5 to the surface of multiple steel templates 1, thereby fastening the steel templates 1 and quickly connecting the steel templates 1 together.

[0032] Specifically, the four corners of the steel template 1 are respectively provided with fixing components 7 for further fastening the steel template 1. The fixing components 7 include clamping blocks 703 that clamp the four corners of multiple steel templates 1 simultaneously, and guide rods 702 that guide the sliding direction of the clamping blocks 703. The guide rods 702 are cross-shaped and have a square cross section. The clamping blocks 703 are fan-shaped and cooperate with one corner of the steel template 1. Multiple clamping blocks 703 slide on the surface of the guide rods 702 respectively. The guide rods 702 are fixed inside the housing 701. Inside the housing 701, there is a threaded plate 704 that rotates through a rotating shaft. The threaded plate 704 and the clamping blocks 703 are respectively provided with mutually cooperating end face threads facing the threaded plate 704. A rotating handle is fixed to the outer end of the rotating shaft. At the four corners of the steel template 1, fan-shaped baffles 8 are fixed respectively, and grooves 9 for avoiding the baffles 8 are opened on the opposite side of the multiple clamping blocks 703.

[0033] It is understandable that by setting the fixing component 7, rotating the handle drives the threaded plate 704 to rotate. With the cooperation of the end face thread, multiple clamping blocks 703 are driven to slide synchronously towards the center of the housing 701 on the surface of the guide rod 702. This allows multiple clamping blocks 703 to clamp the diagonal parts of adjacent steel templates 1 synchronously, thereby further clamping and fixing the steel templates 1. At the same time, under the action of the baffle 8 and the groove 9, the fixing component 7 is prevented from detaching from the surface of the steel template 1.

[0034] Specifically, a first rubber strip 10 is fixed on one side of the steel template 1, and a second rubber strip 11 is fixed on the upper surface of the steel template 1.

[0035] It is understandable that by setting the first rubber strip 10 and the second rubber strip 11, the gap between adjacent steel formwork 1 is sealed to avoid leakage of grout during the pouring process.

[0036] In this invention, during template assembly, multiple arc-shaped steel templates 1 are sequentially joined together to form a cylindrical template. During this process, the steel template 1 is hung on the surface of the clip 201 of the adjacent steel template 1 through the insertion hole 202. After the steel template 1 is pressed down, the positioning pin 301 is inserted into the positioning hole 302 to position and connect the upper and lower steel templates 1, preventing the steel template 1 from moving freely before the complete assembly, thus achieving the purpose of rapid assembly. Then, the fastening rope 5 is passed through multiple limiting rings 4, and the threaded rod 603 is inserted into the tube body 601 through the threaded cap 602, thereby binding the fastening rope 5 to the surface of multiple steel templates 1, thereby fastening the steel template 1 and quickly connecting the steel templates 1 together. Then, the fixing component 7 is installed at the diagonal of the steel template 1, so that multiple clamping blocks 703 clamp and fix the four corners of the steel template 1, improving the fixing effect of the steel template 1.
