[0025] Example

[0026] See also Figure 1-4 As shown:

[0027] The utility model provides a lining end template based on BIM design, comprising: a curved steel plate 10 and a blocking component.

[0028] The curved steel plate 10 is installed at the end of the steel mold used for pouring the tunnel, and the curved steel plate 10 is provided with a steel bar hole 111 at the end of the steel mold for the steel bar to pass through; the sealing assembly is installed at the steel bar hole 111, which is used to seal the end of the steel mold and connect to the steel bar at the end of the steel mold. There are at least four curved steel plates 10, one end of the curved steel plate 10 is provided with a connecting groove, and the other end is provided with a connecting tenon 12, the connecting tenon 12 and the connecting groove form a plug-in fit, and at least four curved steel plates 10 are connected end to end in sequence. Through such a setting, the end of the steel mold can be sealed without affecting the extension of the steel bar at the end of the steel mold, thereby avoiding leakage of slurry during the pouring process. In addition, the use of steel plates can extend the service life.

[0029] The sealing assembly primarily consists of an assembly plate 20 and a fixing portion. The assembly plate 20 is used to seal the rebar holes 111 and engage with the rebar at the end of the steel mold. The fixing portion fits over the rebar at the end of the steel mold and secures the assembly plate 20 and the curved steel plate 10 to the end of the steel mold.

[0030] The curved steel plate 10 is provided with an elongated connecting groove 11. A rebar hole 111 is located at the bottom of the elongated connecting groove 11, and its width is smaller than that of the elongated connecting groove 11. The assembly plate 20 forms a stopper fit with the elongated connecting groove 11. When the curved steel plate 10 is inserted into the elongated connecting groove 11, the fixing portion presses the curved steel plate 10, securing it to the end of the steel mold.

[0031] The assembly panel 20 consists of at least four short panels 21 joined end to end. Each of the short panels 21 has semicircular holes at both ends, which engage the rebar at the ends of the steel mold. This arrangement allows operators to precisely attach the short panels 21 to the rebar one by one, ensuring a secure connection and preventing grout leakage during subsequent pouring.

[0032] The assembly plate 20 is provided with a limiting tenon 23 at both ends; the inner walls of the two ends of the long strip connecting groove 11 are provided with a notch; the limiting tenon 23 and the notch form a tongue and groove. This arrangement makes the connection between the assembly plate 20 and the curved steel plate 10 more stable. During the pouring process, the assembly plate 20 will not be squeezed out of the long strip connecting groove 11, which improves the stability of use.

[0033] The fixing portion is mainly composed of a clamping sleeve 30 and a fastening tie 40 .

[0034] The clamping sleeve 30 comprises two hollow semi-cylinders, each with a semi-circular plug 31 at its bottom. The diameter of the hollow semi-cylinder is smaller than the diameter of the steel bars at the end of the steel mold. A fastening tie 40 is tied to the outside of the clamping sleeve 30. It also includes a rubber sleeve 50, which is fitted over the steel bars at the end of the steel mold. With this arrangement, during actual use, the operator installs the curved steel plate 10 onto the end of the steel mold, then sequentially installs the assembly plate 20, fits the rubber sleeve 50 over the steel bars, with one end of the rubber sleeve 50 abutting against the assembly plate 20. Finally, the clamping sleeve 30 is clamped onto the rubber sleeve 50 and the fastening tie 40 is fixed to the outside of the clamping sleeve 30, thereby completing the sealing of the steel mold end. The entire process is simple and convenient.

[0035] In addition, when the size of the steel mold end is large and the number of steel bars extending from the steel mold end is small, in order to make the arc-shaped steel plate 10 more stably connected to the outside of the steel mold end, clips can be welded on the steel mold and the arc-shaped steel plate 10. The clips are generally set in a snap-on form or a plug-in form, so as to facilitate the disassembly and assembly work after the pouring is completed.

[0036] The curved steel plate 10 and the blocking assembly, as well as other parts in the present invention are first designed in BIM according to the size of the steel mold end, and then the effect after assembly is verified through BIM, so that the template provided by the entire present invention fits more tightly when used, reduces the error rate during use, and improves construction efficiency.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
