[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0025] Example 1, as Figure 1As shown, this embodiment provides a formwork for building construction, including multiple first formworks 1, multiple second formworks 2, and multiple third formworks 3. One end of each first formwork 1 has a corner formwork 4 perpendicular to it. The corner formwork 4 has a T-shaped first splicing groove 5 at its end away from the first formwork 1. Both ends of the third formwork 3 have first splicing blocks 6 that match and interlock with the first splicing grooves 5 of the two corner formworks 4. The first formwork 1 has a T-shaped second splicing groove 7 at its end away from the corner formwork 4. Both ends of the second formwork 2 have second splicing blocks 8 that match the second splicing grooves 7 of the two first formworks 1. During splicing, the third formwork... The first splicing blocks 6 at both ends of the board 3 are inserted from top to bottom into the first splicing grooves 5 on the two corner templates 4 respectively. Then, the second splicing blocks 8 at both ends of the second template 2 are inserted from top to bottom into the second splicing grooves 7 on the two first templates 1 respectively. This completes the splicing of the wall templates. The corner template 4 at one end of the first template 1 avoids the difficulty of splicing at right angles on site, reduces the splicing error at right angles, and prevents grout leakage at right angles. The T-shaped design of the first splicing groove 5 and the first splicing block 6, and the second splicing block 8 and the second splicing groove 7, has strong tensile strength, making the splicing stability of the first template 1, the second template 2, and the third template 3 strong.

[0026] Example 2, as Figure 2 As shown, a further improvement has been made based on Embodiment 1, which also includes multiple fourth templates 9. One end of each fourth template 9 is provided with a third splicing groove 10 that matches the second splicing block 8 on the second template 2, and the other end of each fourth template 9 is provided with a third splicing block 11 that matches the second splicing groove 7 on the first template 1. The third splicing groove 10 on one of the fourth templates 9 is matched and inserted with the third splicing block 11 on another fourth template 9. The fourth templates 9 can be spliced ​​according to the usage situation, and the length of the wall template can be extended according to the actual usage situation, making it more applicable.

[0027] Example 3, as Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, further improvements have been made based on Embodiment 1 or Embodiment 2. An L-shaped reinforcing connecting plate 12 is detachably connected to the corner where the corner template 4 connects to the first template 1. Multiple locking blocks 13 are distributed vertically on both outer walls of the reinforcing connecting plate 12. A locking connecting rod 14 is provided between two locking blocks 13 at the same height on the same side. The locking connecting rod 14 has various length specifications and can be designed according to actual usage. One end of the locking connecting rod 14 is provided with a limiting block 15, and the other end of the locking connecting rod 14 is provided with an external thread 1. 6. The locking block 13 has a connecting hole 17 for the locking rod 14 to pass through. Two locking nuts 18 are threaded onto the external thread 16 of the locking rod 14. A clamping plate 19 is fitted onto the locking rod 14 to clamp the first template 1, second template 2, third template 3, corner template 4, and fourth template 9. The clamping plate 19 has a through hole for the locking rod 14 to pass through. The cross-section of the clamping plate 19 is rectangular. T-shaped fourth splicing blocks 20 are provided on both sides of the corner where the corner template 4 connects to the first template 1 for reinforcement. The inner wall of the connecting plate 12 is provided with a fourth splicing groove 21 that matches the fourth splicing block 20 (the corner template 4 and the first template 1 are integrally formed and the fourth splicing block 20 is provided therein; at this time, the corner template 4, the first template 1, and the fourth splicing block 20 have two structures, which are symmetrical front and back). The bottom end of the fourth splicing block 20 is provided with a limiting support block 22. After the templates as in Embodiment 1 or Embodiment 2 are spliced, the fourth splicing groove 21 on the reinforcing connecting plate 12 matches the fourth splicing block 20 on the corner template 4 and the first template 1. Limiting support block 22 provides limiting support for reinforcing connecting plate 12. Locking connecting rod 14 of corresponding length is selected and passes through the through holes on two locking blocks 13 and top clamping plate 19 on the same side and at the same height. Limiting block 15 limits one end of locking connecting rod 14. The other end of locking connecting rod 14 is locked by two locking nuts 18 threaded connection, which can prevent loosening and eliminate thread gaps. Top clamping plate 19 externally clamps the first template 1, second template 2, third template and fourth template 9, making the stability higher and the grout leakage prevention effect better.

[0028] Example 4, as Figure 7 As shown, the technical feature that differs from that of Embodiment 1 is that the first splicing grooves 5 of the two corner templates 4 are respectively matched and inserted with the first splicing blocks 6 at both ends of the third template 3 to splice out the positive corner and the negative corner.

[0029] Example 5, as Figure 8As shown, the technical feature that differs from Embodiment 4 is that the first splicing groove 5 of the corner template 4 is matched and inserted with the first splicing block 6 at one end of the third template 3, and the first splicing block 6 at the other end of the third template 3 is matched and inserted with the third splicing groove 10 on the fourth template 9. It can also form an inside corner on its own, or, depending on the actual use, the third splicing block 11 on the fourth template 9 can be spliced ​​with the first splicing groove 5 of another corner template 4. In addition, multiple fourth templates 9 can be selected for splicing according to the actual use, which makes it more applicable and can form splicing of exterior walls with different exterior wall lengths. It can also splice both inside and outside corners (not shown in the figure).

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
