[0029] Referring to Figure 3 And Figure 5 As shown, the surface of the support ring body 14 is threadedly connected with a sleeve 4; the fixed bolt 18 is located in the inside of the sleeve 4; when the bottom plate 01 is poured with concrete, the staff can install the sleeve 4 on the surface threaded part of the support ring body 14, the sleeve 4 will close and shield the surface of the support ring body 14 and the fixed bolt 18, reducing the pollution to the surface when the concrete is poured, and the sleeve 4 can also protect the surface threaded part of the support ring body 14 when it is used normally subsequently, reducing the rust caused by oxidation on the surface.

[0030] Referring to Figure 5 As shown, the bottom of the sleeve 4 is fixed with a sealing pad 5; the sealing pad 5 is located between the sleeve 4 and the pressing plate 15; when the staff shields the support ring body 14 and the fixed bolt 18 by rotating the sleeve 4, the sealing pad 5 also contacts the pressing plate 15, the sealing pad 5 will be deformed under the extrusion and fill the gap between the sleeve 4 and the pressing plate 15, reducing the situation that the concrete enters the inside of the sleeve 13 through the gap when it is poured.

[0031] Referring to Figure 5 As shown, the top of the sleeve 4 is fixed with a prompt pad 6; the prompt pad 6 is provided with fluorescence; when the sleeve 4 shields and protects the surface of the support ring body 14, the prompt pad 6 will be exposed to the outside world, when the brightness of the working environment is low, the prompt pad 6 will emit conspicuous fluorescence, so that the staff can know the position of the support ring body 14 by observing the fluorescence, reducing the risk of falling and other dangerous situations caused by the support ring body 14 when the staff moves.

[0032] Referring to Figure 5 As shown in the figure, the surface of the sleeve 4 is fixed with a protrusion 7; the protrusion 7 is located at the top of the sealing gasket 5; because the workers in the construction site generally work with gloves, the surface of the gloves is relatively smooth, and by setting the protrusion 7, the contact area between the gloves and the sleeve 4 can be increased, so that the sleeve 4 is more convenient to rotate.

[0033] Referring to Figure 5 As shown in the figure, the protrusion 7 is a spiral structure; because the protrusion 7 is a spiral structure, the contact area between the protrusion 7 and the palm of the worker is further increased, and the convenience of operating the sleeve 4 is improved. Further increase the contact area between the protrusion 7 and the palm of the worker, improve the convenience of operating the sleeve 4.

[0034] Working principle: The prefabricated composite floor 1 is only with the bottom plate 01 when it is made in the factory. The staff can place the sleeve 13 on the top of the bottom plate 01 according to the subsequent support requirements. When the steel bars 12 are bound to the top of the bottom plate 01, the staff can open a pair of elastic sheets 17 by pulling one side of the elastic sheet 17, and then the adjacent steel bars 12 are clamped into the elastic sheet 17. After that, the elastic sheet 17 can be released. Repeat the above steps until all the elastic sheets 17 inside the surface of the sleeve 13 are clamped into the steel bars 12. At this time, the sleeve 13 will be fixed under the friction of the elastic sheet 17 and the steel bar 12. The support ring body 14 inside the sleeve 13 will be fixed in the sleeve 13 under the connection of the pressing plate 15 and the fixed bolt 18. Then the surface of the bottom plate 01 can be poured with concrete to form the top plate 02. The top of the sleeve 13 and the top of the top plate 02 are flush. After pouring, the prefabricated composite floor 1 can be sent to the construction site and hoisted and installed accordingly. The staff on site can install the corresponding diagonal bracing on the surface of the support ring body 14 to support and fix the prefabricated composite floor 1 (inner wall panel, outer wall panel). After the construction is completed, because the sleeve 13 and the support ring body 14 are clearance fit, the support ring body 14 can be made of steel, and the sleeve 13 is made of soft rubber material, so that the staff can take out the support ring body 14 from the inside of the sleeve 13. When the elastic sheet 17 clamps the steel bar 12, the friction pad 2 also comes into contact with the steel bar 12. The surface of the friction pad 2 has a large friction coefficient, which increases the friction between the elastic sheet 17 and the steel bar 12. Because a plurality of grooves 22 are formed on the surface of the friction pad 2, when the friction pad 2 comes into contact with the steel bar 12, the ribs on the surface of the steel bar 12 will be embedded into the grooves 22, increasing the contact area between the friction pad 2 and the steel bar 12. When the sleeve 13 comes into contact with the bottom plate 01, the support 3 also comes into contact with the bottom plate 01, so that the steel bars 12 at the sleeve 13 can be placed on the surface of the support 3 when they are bound, facilitating the butt joint between the elastic sheet 17 and the steel bar 12. When pouring concrete on the surface of the bottom plate 01, the staff can install the sleeve 4 on the threaded part on the surface of the support ring body 14. The sleeve 4 will shield the surface of the support ring body 14 and the fixed bolt 18, reducing the pollution to the surface during concrete pouring. At the same time, the sleeve 4 can also protect the threaded part on the surface of the support ring body 14 during normal use of the support ring body 14. When the staff shields the support ring body 14 and the fixed bolt 18 by rotating the sleeve 4, the sealing gasket 5 also comes into contact with the pressing plate 15. The sealing gasket 5 will deform under the extrusion and fill the gap between the sleeve 4 and the pressing plate 15. When the sleeve 4 shields and protects the surface of the support ring body 14, the prompt pad 6 will be exposed to the outside world. When the brightness of the working environment is low, the prompt pad 6 will emit conspicuous fluorescence, so that the staff can know the position of the support ring body 14 by observing the fluorescence.Because the workers in the construction site generally work with gloves, the surface of the gloves is relatively smooth, and the contact area between the gloves and the sleeve 4 can be increased by arranging the protrusions 7; because the protrusions 7 are in a spiral structure, the contact area between the protrusions 7 and the palms of the workers is further increased, and the convenience of operating the sleeve 4 is improved. The contact area between the protrusions 7 and the palms of the workers is further increased.

[0035] Obviously, the above embodiments are only examples for clearly illustrating the present application, and are not intended to limit the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments cannot be exhausted, and the obvious changes or variations derived therefrom are still within the protection scope of the present application.
