[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] See also Figures 1 to 3A guide rail for controlling the flatness of a cast-in-place concrete floor structure comprises: a support rod 2 and a guide rail unit 1, wherein a plurality of support rods 2 are vertically arranged on a concrete floor 3 and are arranged linearly; and a guide rail unit 1 is fixed to the top of the support rod 2, and one end of the guide rail unit 1 is formed with an extension end 4, and the extension end 4 of the guide rail unit 1 is inserted into the end of another guide rail unit 1, so that the two guide rail units 1 are connected end to end. Preferably, the extension end 4 is an ear plate fixed to the guide rail unit 1.

[0024] In the present invention, a preferred embodiment is: after the concrete pouring ground construction is completed, support rods 2 are arranged on opposite sides of the concrete ground 3, and a plurality of support rods 2 are arranged in a row. A guide rail unit 1 is fixed on the top of the support rod 2, and an extension end 4 is formed at one end of the guide rail unit 1. By inserting the extension end 4 into the end of another guide rail unit 1 away from the extension end 4, the two guide rail units 1 are connected end to end, so that it is suitable for ground projects of different areas, and can be quickly turned around and reused.

[0025] Furthermore, a threaded hole 41 is formed on the protruding end 4, and a connecting hole 12 is formed at the end of the guide rail unit 1 corresponding to the threaded hole 41, and the two guide rail units 1 are fixedly connected by passing a bolt 11 through the threaded hole 41 and the connecting hole 12. The protruding end 4 and another guide rail unit 1 are fixed by the bolt 11 to increase the connection strength of the two guide rail units 1 and prevent the guide rail from being disconnected when in use.

[0026] Furthermore, a mounting hole is formed at the bottom of the guide rail unit 1 corresponding to the support rod 2, and the support rod 2 is inserted into the mounting hole. Preferably, the diameter of the mounting hole is slightly larger than the diameter of the support rod 2 so as to facilitate the insertion of the support rod 2.

[0027] Furthermore, the support rod 2 is threadedly connected with a fixing nut 21, and the fixing nut 21 is located below the guide rail unit 1. By screwing the fixing nut 21, the length of the support rod 2 inserted into the guide rail unit 1 can be adjusted, so that the height of the guide rail unit 1 is adjustable. By adjusting the height of the guide rail unit from the concrete pavement, the sheep's foot roller and the smooth roller can fit the surface of the concrete, thereby leveling the concrete. Preferably, the outer diameter of the fixing nut 21 is larger than the diameter of the mounting hole, so as to ensure that the fixing nut 21 can support the guide rail unit 1 and prevent the guide rail unit 1 from falling off.

[0028] Furthermore, a first external thread is formed on the top of the support rod 2 , and the first external thread is threadedly connected to the fixing nut 21 .

[0029] Further, an embedded section is formed at the bottom of the support rod 2, and the embedded section is threadedly connected with an anti-pullout nut 22. By embedding the anti-pullout nut 22 in the concrete, the anti-pullout effect of the support rod 2 is increased to prevent the support rod 2 from being easily pulled out.

[0030] Furthermore, a second external thread is formed at the bottom of the support rod 2, and the anti-pullout nut 22 is threadedly connected to the second external thread.

[0031] Furthermore, the support rods 2 are arranged in two rows. The guide rail unit 1 is supported by the two rows of support rods 2, thereby avoiding stress concentration in the guide rail unit 1.

[0032] Furthermore, the guide rail unit 1 is made of a rectangular tube.

[0033] Furthermore, the diameter of the protruding end 4 is smaller than the inner diameter of the rectangular tube.

[0034] The following is an explanation of the use of a guide rail for controlling the flatness of a cast-in-place concrete floor structure according to the utility model.

[0035] After the concrete pouring floor construction is completed, support rods 2 are arranged on opposite sides of the concrete floor 3, and several support rods 2 are arranged in a row. A guide rail unit 1 is fixed on the top of the support rod 2, and an extension end 4 is formed at one end of the guide rail unit 1. The extension end 4 is inserted into the end of another guide rail unit 1 away from the extension end 4 to connect the two guide rail units 1 end to end, and the two guide rail units 1 are fixed by bolts 11, so that it is suitable for ground projects of different areas and can be quickly turned around and reused.
