[0019] See also Figures 1 to 3, which is the first embodiment of the utility model, and this embodiment provides a technical solution: an anti-crack stripboard inner partition wall door opening structure, comprising two door frame strips 1 and a door head plate 2 mounted between the two door frame strips 1, the surface of the door head plate 2 and the door frame strips 1 are both provided with two T-shaped paddle storage grooves 5, the top surface of the door frame strips 1 is fixed with a connecting plug 11, the bottom surface of the door head plate 2 is provided with a connecting slot 21 corresponding to the connecting plug 11, the door head plate 2 and the door When the frame strips 1 are spliced, the connecting plug block 11 is inserted into the connecting slot 21, and the door frame strips 1 and the door head board 2 can be limited during the grouting process. The T-shaped slurry storage groove 5 is filled with anti-cracking mortar 6, which is specifically made of 10% cement, 50% river sand, 12% fly ash, 4% latex powder, 0.8% acrylic fiber, 0.6% hydroxypropyl methylcellulose, 0.4% water repellent, 0.8% wood fiber, 0.5% starch ether and water. Wait for the anti-cracking mortar to be poured into the grouting machine. After the mortar 6 is completely solidified, the door frame strip 1 and the door head plate 2 can be connected together, and the two T-shaped slurry storage grooves 5 can form an I-shaped structure to ensure the connection stability of the door frame strip 1 and the door head plate 2 after the anti-cracking mortar 6 is solidified, and the tensile effect is increased. Grouting holes 51 are opened through the side walls of the T-shaped slurry storage grooves 5, and the operator can inject anti-cracking mortar 6 into the T-shaped slurry storage grooves 5 through the grouting holes 51. When the door opening structure is actually spliced, the door head plate 2 is first erected between the two door frame strips. The top of the board 1 is connected so that the connecting plug block 11 is inserted into the connecting slot 21, and then the plug rod 31 is sequentially passed through the perforation A32 and the perforation B33 to realize the connection limit between the door frame strip board 1 and the door head board 2, and then the anti-cracking mortar 6 is injected into the T-shaped slurry storage groove 5 through the grouting hole 51, and then the sealing mortar 34 is injected into the rectangular outer groove 22, and the mortar is waited for to solidify, and then the door frame strip board 1 and the door head board 2 can be spliced ​​into the strip board inner partition wall door opening structure, which also includes the plug-in stabilizing structure 3;
