Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a rapid installation structure for a foundation pit air film. Background Technique

[0002] When fixing an air film at a construction site of a building project, air film fixing parts are usually required. Taking a building with an air film reinforced concrete structure as an example, a building with an air film reinforced concrete structure uses a soft fabric with excellent performance (i.e., an air film) as the outer film and fixes it on a circular foundation constructed according to the design requirements. Air is continuously input into the air film and the air pressure inside the air film is kept constant as the construction load support. Subsequently, an interface agent, a polyurethane foam layer, construction reinforcement binding, structural reinforcement layer-by-layer binding, and concrete spraying layer-by-layer are carried out inside the air film in sequence, and finally a structural system with a certain stiffness and capable of covering a large space is formed.

[0003] The existing installation structure for a foundation pit air film usually uses embedded bolts to install and fix pressing pieces, so as to realize the connection between the air film and the foundation pit. During the process of embedding the bolts, the position may shift, which affects the connection between the pressing piece and the bolt, and thus affects the installation efficiency.

[0019] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment 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 with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] Please refer to Figures 1-4, the embodiments provided by the present utility model: a rapid installation structure for a foundation pit air film, including a workbench 1 and a limit seat 2. The limit seat 2 is made of cast iron and is L-shaped. Two embedded bolts 3 are symmetrically inserted on the side wall of the workbench 1 close to the limit seat 2. Two first holes 11 are symmetrically opened on the side wall of the limit seat 2 for the embedded bolts 3 to be inserted. The internal dimensions of the first holes 11 are adapted to the external dimensions of the embedded bolts 3, which improves the stability of the insertion of the embedded bolts 3. Anti-slip nuts 5 are threadedly connected to the outer surfaces of the two embedded bolts 3 to limit the lateral displacement of the limit seat 2. An air film layer 15 is installed at the top of the workbench 1. The air film layer 15 is L-shaped and clamped between the workbench 1 and the limit seat 2, increasing the contact area between the air film layer 15 and the workbench 1 and the limit seat 2, improving the anti-slip property of the installation of the air film layer 15, and thus improving the stability of the installation of the air film layer 15. Positioning seats one 7 are fixedly provided at the ends of the two embedded bolts 3. Connecting members 8 are fixedly provided at the other ends of the positioning seats one 7. Two support columns 9 are symmetrically fixedly provided at the top of the connecting members 8. The ends of the positioning seats one 7 are flush with the side wall of the workbench 1, facilitating the horizontal positioning of the installation of the support columns 9. The tops of the two support columns 9 are fixedly provided with positioning seats two 10. The tops of the positioning seats two 10 are flush with the surface of the workbench 1, facilitating the positioning of the height of the installation of the embedded bolts 3. The embedded bolts 3, the positioning seats one 7, the connecting members 8, the support columns 9, and the positioning seats two 10 are all made of cast iron and are fixedly connected to form an integral structure, improving the overall stability of the installation of the embedded bolts 3, and thus improving the convenience of the casting and positioning of the positioning seats one 7. The first holes 11 are symmetrically distributed and adapted to the external dimensions of the embedded bolts 3, thus improving the convenience of the installation and positioning of the limit seat 2, and thus improving the efficiency of the air film installation.

[0021] A first notch 12 is opened at the middle position of the limit seat 2 close to the first holes 11. A pull ring 4 is fixedly provided at the middle position of the connecting member 8 close to the positioning seat one 7. The pull ring 4 facilitates the connection of the cable. The cable is usually made of nylon and is woven on the outer surface of the air film layer 15 to enhance the overall stability of the air film layer 15. The cable is a prior art and will not be elaborated here. The pull ring 4 passes through the first notch 12.

[0022] Two second holes 13 are symmetrically opened at the top position of the limit seat 2. The second holes 13 and the first holes 11 are in the same horizontal plane. The second holes 13 and the positioning seats two 10 are in the same vertical direction. Limit bolts 6 are inserted into the two second holes 13, improving the convenience of the limit bolts 6 and the installation and positioning. Threaded holes three 14 are opened on the surfaces of the positioning seats two 10 for the limit bolts 6 to be threadedly connected. The threaded holes three 14 sequentially penetrate through the positioning seats two 10 and the support columns 9 for the limit bolts 6 to be threadedly connected, improving the firmness of the connection between the limit seat 2 and the workbench 1. The limit bolts 6 pass through the second holes 13 and the air film layer 15 and are threadedly connected inside the threaded holes three 14, further improving the stability of the installation of the air film layer 15.

[0023] Working principle: When the rapid installation structure of the foundation pit air film is in use, the operator first pours the connecting piece 8 into the interior of the workbench 1, making the end of the first positioning seat 7 flush with the side wall of the workbench 1 and the top of the second positioning seat 10 flush with the surface of the workbench 1, thereby improving the installation and positioning accuracy of the two embedded bolts 3. After the workbench 1 solidifies, the air film layer 15 is laid in an L shape on the top of the workbench 1. The two first holes 11 are sequentially inserted onto the outer surface of the embedded bolts 3, and the anti-slip nuts 5 are sequentially threadedly connected onto the outer surface of the embedded bolts 3, thereby restricting the displacement of the limit seat 2. The limit seat 2 pressing on the top of the air film layer 15 can prevent the air film layer 15 from sliding, thus improving the rapid installation of the air film layer 15 and the installation efficiency of the air film.

[0024] Secondly, the limit bolt 6 is passed through the second hole 13 and the air film layer 15 and threadedly connected into the third hole 14, improving the firmness of the installation of the top of the limit seat 2, further increasing the pressure exerted by the limit seat 2 on the surface of the air film layer 15, and further improving the installation stability of the air film layer 15.
