DETAILED DESCRIPTION

[0016] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figure 1-4 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the drawings in the specification.

[0017] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0018] Embodiment 1, a cable net connection device for air membrane building construction, including a bottom plate 1 and a top plate 2, both the bottom plate 1 and the top plate 2 are provided with a cross limit groove 3, two groups of main steel cables 4 are arranged in the cross limit groove 3, and half-track circle limit grooves 5 are provided on the bottom plate 1 and the top plate 2, a limit block 6 is provided on the bottom plate 1, a limit hole 7 cooperating with the limit block 6 is provided on the top plate 2, a positive armature 8 is provided on the limit block 6, a negative armature 9 cooperating with the positive armature 8 is provided in the limit hole 7, a diagonal cable 10 is provided in the half-track circle limit groove 5, and a fastening bolt 11 is provided between the bottom plate 1 and the top plate 2; the limit block 6 and the limit hole 7 are both located at the center of the half-track circle limit groove 5; the diagonal cable 10 includes a diagonal rope 12 and a buckle 13; the bottom plate 1 and the top plate 2 are both made of carbon steel material.

[0019] When in use, the top plate 2 is separated from the bottom plate 1 and moved to the position corresponding to the main steel cable 4, so that the limit block 6 corresponds to the limit hole 7, and the bottom plate 1 is moved so that the positioning block enters the limit hole 7. Since the positioning block and the limit hole 7 are respectively provided with a positive armature 8 and a negative armature 9, the positive armature 8 and the negative armature 9 attract each other under the action of the positive armature 8 and the negative armature 9, so as to achieve the purpose of temporary fixation. During the installation of the air film, it is necessary to install the array bottom plate 1 and the top plate 2 on the main steel cable 4 for connection. Therefore, it is necessary to continuously adjust the position of the top plate 2 and the bottom plate 1 on the main steel cable 4. Under the action of the armature 8 and the negative armature 9, it is convenient for the operator to adjust the position. Compared with the prior art, there is no need to adjust the position of the top plate 2 and the bottom plate 1 by using the diagonal fixing method of bolts, which improves the installation speed. Before the positive armature 8 and the negative armature 9 are matched, the inclined cable 10 is placed in the semi-runway circle limit groove 5. After the positive armature 8 and the negative armature 9 are matched, the inclined cable 10 is limited to the semi-runway circle limit groove 5. The inclined tension increases the overall stability of the air film. After the position of the bottom plate 1 and the top plate 2 is adjusted, the top plate 2 and the bottom plate 1 are fixed by tightening the bolts 11.

[0020] Embodiment 2, on the basis of embodiment 1, a wear-resistant plate is provided in the semi-runway circular limit groove 5, which on the one hand prevents the inclined cable 10 from slipping in the semi-runway circular limit groove 5, and on the other hand increases the friction between the inclined cable 10 and the inner wall of the semi-runway circular limit groove 5, making it more firmly fixed inside.

[0021] The above description is only for illustrating the present invention, and it should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the protection scope of the present invention.
