Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 3 As shown, the embodiment of the utility model provides a device for facilitating the leveling and film covering of a concrete floor, comprising a leveling plate 1, a support frame 2, and a clamp 5. Among them:

[0026] The collecting plate 1 is used to collect and level the concrete floor 7, and the collecting plate 1 is also provided with a traction member for pulling and moving the collecting plate 1. The support frame 2 is installed on the collecting plate 1, and the film is rolled on the film roll 4. The support frame 2 includes a cross bar 22 for passing the film roll 4, and the film roll 4 is installed on the support frame 2 through the cross bar 22.

[0027] The clamp 5 fixes the end of the clamped film 3 away from the film roll 4 to the external structure. Figure 1 As shown, the clamp 5 fixes the end 3 of the film on the floor side form 8, so that when the flat plate 1 moves away from the floor side form 8 through the traction member, the concrete floor 7 is flattened and the flattened concrete slab surface is simultaneously covered with the film for maintenance.

[0028] As a preferred implementation, Figure 1 and Figure 2As shown, the support frame 2 further includes two vertical rods 21 detachably connected to the two ends of the cross bar 22 , and the ends of the two vertical rods 21 are fixed on the receiving plate 1 .

[0029] As a preferred implementation, Figure 2 As shown, the cross section formed by the two vertical poles 2, the collecting plate 1 and the cross bar 22 is an inverted trapezoid, and the length of the cross bar 22 is not shorter than the width of the collecting plate 1, which is conducive to the film installation width being consistent with the width of the collecting plate 1, and the upper and lower position projections being consistent, so that the collecting surface positions can be effectively covered to avoid the situation where the concrete slab surface is leaking.

[0030] As a preferred embodiment, the cross section of the cross bar 22 is circular, which is beneficial to the rotation of the film roll 4 of the film.

[0031] As a preferred implementation, Figure 1 and Figure 2 As shown, the support frame 2 also includes a pressing rod 23 for pressing the film 3. Both ends of the pressing rod 23 are vertically connected to connecting rods 231 respectively. The end of the connecting rod 231 away from the pressing rod 23 is provided with a first opening, such as Figure 2 As shown, both ends of the crossbar 22 extend out of the vertical pole 21 to form a flange crossbar 221, and a second opening is provided on the vertical pole 21 for the flange crossbar 221 to pass through. An external thread is formed on the flange crossbar 221, and the connecting rod 231 is passed through the first opening on the flange crossbar 221 and screwed on the flange crossbar 221 through the nut 222.

When the support frame 2 is installed, the connecting rod 231 is first placed on the outside of the vertical pole 21, and the first opening of the connecting rod 231 is aligned with the second opening on the vertical pole 21, and then the crossbar 22 is passed through the first opening and the second opening in sequence, and then the nut 222 is tightened on the outside of the crossbar 22, i.e., at the position of the flange crossbar 221 to fix the crossbar 22 and the connecting rod 231.

[0032] As a preferred implementation, Figure 1 As shown, the cross section of the pressure rod 23 is circular, which increases the contact surface between the pressure rod 23 and the film 3, which is beneficial to the film coverage and avoids damage. Figure 1 and Figure 2 As shown, when the compression rod 23 is on the membrane 3, the height from the concrete floor 7 is slightly higher than the height of the flat plate 1, which is beneficial to reduce the impact of wind load on the membrane covering.

[0033] As a preferred implementation, Figure 3 As shown, the fixture 5 includes a fixing block 51 ( Figure 3The blue line represents the film 3, which is wrapped around the fixing block 51, and the clip 52 used to fix the fixing block 51 to the external structure.

The support frame 2 is installed on the flat plate 11.

[0036] As a preferred embodiment, the traction member is a pull rod 6 fixed on the flat plate 11 , and a handle is further provided at one end of the pull rod 6 away from the flat plate 11 .

[0037] The utility model is a device for leveling and covering concrete floors with films. First, the film roll 4 of the film is installed on the support frame 2. The connecting rod 231 is placed on the outside of the vertical rod 21 and the openings thereof are aligned. The film roll 4 is placed on the inside of the vertical rod 21 and the core of the film roll 4 is aligned with the openings thereof. Then, the cross bar 22 is passed through the first opening, the second opening and the film roll 4 in sequence, and the nut 222 is tightened.

[0038] The film 3 is then wrapped around the fixing block 51 for at least one circle, and then the fixing block 51 is placed into the accommodating cavity, and then the clip 52 is clamped on the floor side form 8 .
