[0002] The prefabricated installation formwork used in the construction process is a temporary support structure that allows concrete to be poured and solidified into a certain shape and size. The use of prefabricated installation formwork for construction can greatly improve the construction efficiency of the construction project, and can also flexibly adapt to the construction needs of contemporary diverse architectural shapes.

[0003] Traditional installation template assembly needs to be fixed with screws. Although the screw fixing method is quick and easy, it is easy to damage the installation template during the disassembly process. Therefore, the prior art specifically adopts the method shown in the patent publication number CN216740668U to fix the template. Although the ratchet pawl bite method can achieve fixation between templates, installing the ratchet pawl on the outside of the template tends to increase the volume of the template itself, affecting the convenience of using the template. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a prefabricated installation mold for construction. By installing fixing pins for locking the positions of the first mold and the second mold inside the first mold and the second mold, no additional space is occupied, which helps to reduce the space occupied by the first mold and the second mold, thereby enhancing the convenience of using the utility model.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a prefabricated installation mold for construction, comprising a first mold and a second mold, wherein the second mold is arranged on the top of the first mold, and a mold fixing component for assembly is arranged between two of the first molds and between two of the second molds;

[0007] When the second template is assembled on top of the first template, the first limiting groove and the second limiting groove are connected, and the fixing pin is simultaneously inserted into the connected first limiting groove and the second limiting groove to lock the two first templates and the two second templates spliced ​​together.

[0008] Preferably, the cross-sections of the fixing pin and the first limiting groove are both trapezoidal, and the fixing pin matches the first limiting groove and the second limiting groove.

[0009] Preferably, water-swellable waterstop strips are embedded in both side walls of the fixing pin, and waterstop strip installation grooves for accommodating the water-swellable waterstop strips are opened on both side walls of the fixing pin. The water-swellable waterstop strips are bonded to the inside of the waterstop strip installation grooves by strip adhesive.

[0010] Preferably, the first limiting groove does not pass through the bottom of the first template, and the second limiting groove passes through the second template, which is used to prevent the fixing pin from escaping from the first template, and the top of the fixing pin is provided with two rectangular holes symmetrically distributed on the left and right.

[0011] Preferably, a template upper and lower alignment component for aligning the first template with the second template is provided between the first template and the second template;

[0012] The template upper and lower alignment component includes a square steel tube installed inside each first template and each second template, the top of the square steel tube extends from the top of the first template and the top of the second template, and the bottom of the first template and the bottom of the second template are provided with square grooves for accommodating the square steel tubes.

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] In order to address the shortcomings of the existing technology, such as Figure 1 As shown, the utility model provides a prefabricated installation form for construction, comprising a first form 1 and a second form 2, wherein the second form 2 is arranged on the top of the first form 1, and a form fixing assembly 3 for assembly is arranged between the two first form 1 and between the two second form 2;

[0036] Specifically, Figure 2-11 As shown, the template fixing assembly 3 includes a first limiting groove 32 provided on the side wall of each first template 1 and a second limiting groove 33 provided on the side wall of each second template 2. A fixing pin 31 is inserted between the two first limiting grooves 32 that are connected when the two first templates 1 are spliced ​​together, so as to lock the two first templates 1 spliced ​​together.

[0037] When the second template 2 is assembled on top of the first template 1, the first limiting groove 32 and the second limiting groove 33 are connected, and the fixing pin 31 is inserted into the connected first limiting groove 32 and the second limiting groove 33 at the same time, so as to lock the two first templates 1 and the two second templates 2 spliced ​​together; wherein, the first limiting groove 32 does not pass through the bottom of the first template 1, and the second limiting groove 33 passes through the second template 2, so as to prevent the fixing pin 31 from falling out from the first template 1;

[0038] When splicing two first templates 1 together, first align the fixing pins 31 on one side of the two first templates 1, and then insert the second limiting groove 33 into the aligned fixing pin 31. Similarly, when splicing the second template 2 with the first template 1, it is also necessary to align the first limiting grooves 32 on one side of the two second templates 2, and insert the fixing pin 31 from top to bottom into the two connected fixing pins 31 and the two first limiting grooves 32.

[0039] In the utility model, the cross-sections of the fixing pin 31 and the first limiting groove 32 are both trapezoidal, and the fixing pin 31 is consistent with the first limiting groove 32 and the second limiting groove 33. The shape of the fixing pin 31, which is thin in the middle and thick at both ends, is used to limit the position of the fixing pin 31, and the first template 1 and the second template 2 spliced ​​together are locked together by the fixing pin 31 to prevent the two first templates 1 or the two second templates 2 from detaching.

[0040] Moreover, the fixing pin 31 for locking the position of the first template 1 and the second template 2 in the utility model is installed inside the first template 1 and the second template 2, and does not occupy additional space, which helps to reduce the space occupied by the first template 1 and the second template 2 and enhances the convenience of using the utility model.

[0041] And if Fig.11As shown, two rectangular holes 37 symmetrically distributed on the left and right are opened at the top of the fixing pin 31. The staff can insert a rod-shaped tool such as a steel bar into the rectangular hole 37 to facilitate the staff to pull out the fixing pin 31 from the first template 1 and the second template 2 for reuse.

[0042] In addition, in order to align the first template 1 and the second template 2 that are spliced ​​together, as shown in FIG. Figure 1 As shown, a template upper and lower alignment component 4 for aligning the first template 1 with the second template 2 is provided between the first template 1 and the second template 2;

[0043] like Figure 2-5 As shown in , 8 and 9, the template upper and lower alignment component 4 includes a square steel tube 41 installed inside each first template 1 and each second template 2, the top of the square steel tube 41 extends from the top of the first template 1 and the top of the second template 2, and the bottom of the first template 1 and the bottom of the second template 2 are provided with a square groove 42 for accommodating the square steel tube 41, and the upper and lower alignment of the first template 1 and the second template 2 is achieved by inserting the square steel tube 41 into the square groove 42;

[0044] Similarly, a template left-right alignment component 5 for alignment is provided between the two first templates 1 and between the two second templates 2;

[0045] like Figure 2 , 4 As shown in Figures 6, 7 and 9, the template left-right alignment component 5 includes a plurality of rectangular short rods 51 fixed on one side of the first template 1 and on one side of the second template 2. A plurality of rectangular grooves 52 are provided on the first template 1 relative to the side where the rectangular short rods 51 are fixed and on the second template 2 relative to the side where the rectangular short rods 51 are fixed. The left-right alignment of the two first templates 1 and the two second templates 2 is achieved by inserting the rectangular short rods 51 into the rectangular grooves 52.

[0046] In order to prevent the fixing pin 31 from loosening, Fig.10 and 11 As shown, water-swellable waterstop strips 34 are embedded in both side walls of the fixing pin 31, and waterstop strip installation grooves 36 for accommodating the water-swellable waterstop strips 34 are opened on both side walls of the fixing pin 31. The water-swellable waterstop strips 34 are bonded to the inside of the waterstop strip installation grooves 36 by strip adhesive 35. After the fixing pin 31 is inserted into the first template 1 and the second template 2, some water can be injected into the gap between the fixing pin 31 and the first template 1 or the second template 2. The water-swellable waterstop strip 34 expands in water to increase its volume and fill the gap between the first template 1 and the fixing pin 31 and the gap between the second template 2 and the fixing pin 31, thereby further enhancing the stability of the connection.
