[0019] Reference herein to "embodiments" means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive of other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0020] Please refer to Figures 1-4 , the embodiment provided by the utility model: a connecting device for a foundation pit air film component, including a building foundation 1 and a mounting seat 2 fixedly arranged at the top of the building foundation 1. The building foundation 1 is made of concrete and is fixedly connected to 2 after solidification, improving the firmness of the installation of the mounting seat 2. A groove 1 3 is opened at the top of the mounting seat 2 for clamping the air film. A fastener 4 is clamped inside the groove 1 3. The fastener 4 supports at the top of the air film to limit the air film. Grooves 2 7 are opened at the top of the fasteners 4, reducing the self-weight of the fasteners 4 and saving material costs. The external dimensions of the bottom ends of the fasteners 4 are all adapted to the internal dimensions of the groove 1 3, improving the stability of the fasteners 4 pressing on the top of the air film. The air film is clamped between the mounting seat 2 and the fasteners 4, which can increase the contact area, thereby increasing the frictional resistance and improving the overall stability of the air film installation. Two positioning blocks 5 are symmetrically and fixedly arranged on the side wall of the mounting seat 2. Clamping blocks 6 are fixedly arranged on the side walls of the fasteners 4 close to the positioning blocks 5. Slots 12 are opened on the surfaces of the positioning blocks 5 for the clamping blocks 6 to be inserted. The two clamping blocks 6 are made of cast iron and are L-shaped. Through holes 1 11 are opened on the side walls of the positioning blocks 5, sequentially penetrating through the positioning blocks 5 and the mounting seat 2. A limiting bolt 8 is threadedly connected inside the through hole 1 11. Through holes 3 14 are opened on the side walls of the clamping blocks 6. The internal dimensions of the through holes 3 14 are the same as the internal dimensions of the through hole 1 11. The external dimensions of the clamping blocks 6 are all adapted to the internal dimensions of the slots 12, improving the convenience of positioning the through hole 1 11 and the through hole 3 14, and thus facilitating the threaded connection of the limiting bolt 8 inside the through hole 1 11 and the through hole 3 14 in sequence, thereby improving the firmness of the connection between the fasteners 4 and the mounting seat 2.

[0021] On two side walls of the mounting base 2, a number of groups of bumps 9 are symmetrically fixed. The bumps 9 and the mounting base 2 are both made of cast iron and are fixedly connected to form an integral structure. The bumps 9 increase the contact area between the mounting base 2 and the building foundation 1, and improve the stability of the connection between the mounting base 2 and the building foundation 1.

[0022] On the side wall of the mounting base 2 close to the positioning block 5, a number of second holes 13 are opened. The number of second holes 13 all penetrate through the side wall of the mounting base 2 and are connected to the first groove 3. The second holes 13 can be penetrated by the nylon thread at the edge of the air film, which is convenient for threading and tying the rope, and further improves the firmness of the air film installation.

[0023] A buffer pad 10 is clamped at the inner bottom of the first groove 3. The buffer pad 10 is made of rubber and is strip-shaped. The width of the buffer pad 10 is adapted to the inner width of the first groove 3. The surface of the buffer pad 10 is rough and elastic, which can improve the stability of the air film clamped inside the first groove 3, and improve the stability of the connection between the air film and the mounting base 2 and the fastener 4.

[0024] Working principle: When this kind of connection device for the air film component in the foundation pit is in use, the operator first pours the mounting base 2 on the top of the building foundation 1. The bumps 9 increase the contact area between the mounting base 2 and the building foundation 1. After the building foundation 1 solidifies, the stability of the connection between the mounting base 2 and the building foundation 1 is improved. The air film is clamped along the inner side wall of the first groove 3, and then the fastener 4 is supported on the surface of the air film, so that the fastener 4 is clamped inside the first groove 3. The external dimensions of the bottom end of the fastener 4 are all adapted to the internal dimensions of the first groove 3, which increases the contact area between the air film and the mounting base 2 and the fastener 4, thereby increasing the frictional resistance and improving the overall stability of the air film installation. The clamping blocks 6 are sequentially inserted into the slots 12 to improve the convenience of positioning the first holes 11 and the third holes 14. The limit bolts 8 are sequentially screwed into the first holes 11 and the third holes 14, which improves the stability of the connection between the mounting base 2 and the fastener 4, and thus improves the overall stability of the connection between the air film and the building foundation 1.
