A limit component 8 is fixedly installed on the other end of the connecting component 4 away from the aluminum formwork body 1. Two identical connecting components 4 are provided.

[0035] Combination Figure 5 As shown, in some embodiments of this example, the connecting component 4 in the aluminum template connector specifically includes a connecting plate 401. The connecting plate 401 has a slot 402 on the side near the insert 5. A card plate 405 is inserted and installed on the side of the connecting plate 401 near the aluminum template body 1. A limiting groove 409 is provided on the side of the connecting plate 401 near the insert 5.

[0036] Further integration Figure 2 and Figure 3 As shown, a connecting block 403 is fixedly installed on the top of the connecting plate 401 near the aluminum template body 1 in this connecting assembly 4. The top of the connecting block 403 is provided with a positioning hole 3 404. Positioning holes 406 are provided on the left and right sides of the clamping plate 405. Positioning hole 3 404 is adapted to positioning hole 2 3, and positioning hole 406 is adapted to positioning hole 1 2.

[0037] In the connecting component 4 with such a structure, by cooperating with positioning hole three 404 and positioning hole four 406, when connecting two adjacent aluminum template bodies 1, positioning hole three 404 can overlap with positioning hole two 3, and positioning hole four 406 can overlap with positioning hole one 2. Then, by fastening anchor bolts, double fixation between the two aluminum template bodies 1 can be achieved, which can improve its stability.

[0038] Further, the right side of the inner part of the clamping plate 405 in the connection assembly 4 is fixedly provided with a non-slip pad 407, which is a rubber non-slip pad. The connecting plate 401 is provided with a reinforcing block 408 on the side close to the aluminum formwork body 1.

Through the design of the two limiting bolts 803, the pressure received by a single limiting bolt 803 can be dispersed, the force of the limiting block 802 can be dispersed, the service life can be improved, and the stability of the limiting block 802 can be further improved.

[0044] Further in combinationFigure 6 As shown, in this example, two connecting assemblies 4 are fixedly connected with a hinge 9 for rotation on one side close to the limiting assembly 8, the insertion sleeve 5 is installed in the insertion assembly 4 through the insertion slot 402, the insertion sleeve 5 is provided with a limiting hole 6 on both sides, and the other end of the insertion sleeve 5 away from the aluminum formwork body 1 is fixedly installed with a reinforcing rib 7. Through the design of the hinge 9, when not in use, the hinge 9 can realize the rotation of the two connecting assemblies 4, which can facilitate storage. At the same time, when connecting two aluminum formwork bodies 1 distributed vertically, it can also facilitate connection, which can improve the diversity of the overall connecting piece and facilitate popularization and use.

[0045] In order to further illustrate the composition characteristics and functions of the aluminum formwork connecting piece given in the above example, the following illustrates its operation process.

Then fastening anchor bolts are used for fastening, which can realize the double fixation between the two aluminum formwork bodies 1 and improve the stability.

[0047] Through the design of the non-slip pad 407, when the clamping plate 405 is clamped into the inside of the aluminum formwork body 1, the friction between the clamping plate 405 and the aluminum formwork body 1 can be increased, the overall anti-skid property can be improved, and through the design of the reinforcing block 408, after the clamping plate 405 is installed, the reinforcing block 408 can be inserted, the resistance to deformation of the clamping plate 405 can be improved, and the stability between the two can be further improved.

[0048] Through the design of the fixed frame 801, when connecting two adjacent aluminum formwork bodies 1, the fixed frame 801 can limit the limiting block 802, avoiding falling easily; through the cooperation of the limiting block 802 and the limiting slot 409, when connecting, the limiting block 802 can be put into the limiting slot 409, and then rotating the limiting bolt 803 can realize the limiting of the limiting block 802, at the same time, the connecting plate 401 cannot be rotated, which can realize the limiting of the connecting plate 401, avoiding rotation, thereby connecting the aluminum formwork body 1; through the design of the two limiting bolts 803, the pressure received by a single limiting bolt 803 can be dispersed, the force of the limiting block 802 can be dispersed, the service life can be improved, and the stability of the limiting block 802 can be further improved.

[0049] Through the design of the hinge 9, when not in use, the hinge 9 can realize the rotation of the two connecting assemblies 4, which can facilitate storage. At the same time, when connecting two aluminum formwork bodies 1 distributed vertically, it can also facilitate connection, which can improve the diversity of the overall connecting piece and facilitate popularization and use.
