[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The utility model provides Figure 1-5The present invention shows a cast-in-situ dense-rib floor that is easy to install, comprising a floor trough 1. An extension ring 2 is provided on the top of the floor trough 1. Rotating members 3 and positioning members 4 are symmetrically provided on the sides of the extension ring 2. The positioning members 4 are provided at the connection between the rotating member 3 and the extension ring 2. The positioning members 4 are used to limit the rotation of the rotating member 3.

[0022] It should be noted that the inner wall of the floor trough 1 is provided with multiple groups of reinforcing ribs 201 for increasing the supporting strength of the floor trough 1. The floor trough 1, the extension ring 2 and the reinforcing ribs 201 are all made of plastic. The floor trough 1 and the extension ring 2 are extruded as a whole, and the reinforcing ribs 201 are arranged in the shape of columnar strips.

[0023] Specifically, the rotating member 3 includes a sleeve rod 301 and a movable rod 302. The sleeve rod 301 is sleeved on the outside of the movable rod 302. The positioning member 4 is provided on the side of the sleeve rod 301. A locking portion 5 for fixing the sleeve rod 301 and the movable rod 302 is provided at the intersection of the sleeve rod 301 and the movable rod 302.

[0024] It should be noted that the sleeve rod 301 is a hollow square tube, and the movable rod 302 is a square solid stainless steel tube;

[0025] Specifically, the locking portion 5 includes a cylinder 501, one end of which is inserted and connected to the end side of the movable rod 302, and a locking rod 502 is sleeved inside the cylinder 501, and the end of the locking rod 502 is inserted and connected to the inner wall of the sleeve rod 301;

[0026] It should be noted that a cylindrical groove is formed at the end of the movable rod 302 for the cylinder 501 to be inserted therethrough. The groove wall is glued to the outer side of the cylinder 501 and fixed thereto. A cylindrical hole is formed on the inner wall of the sleeve rod 301 for the locking rod 502 to be inserted therethrough. The end of the locking rod 502 is configured as a spherical convex shape, and the spherical convex end is provided with a cylindrical edge. The cylindrical edge contacts the cylindrical hole to prevent the locking rod 502 from being squeezed by the inner wall of the cylindrical hole and retracting into the interior of the cylinder 501 when the movable rod 302 is subjected to force.

[0027] The cylinder 501 is provided with a rebound portion inside for pushing the locking rod 502 to move;

[0028] Specifically, the rebound portion includes a limiting ring 503, a movable ring 504, and a compression spring 505, which are sleeved on the outside of the locking rod 502. The limiting ring 503 is arranged on one side of the movable ring 504 close to the extension ring 2, and the compression spring 505 is arranged on the other side of the movable ring 504. The outer side of the limiting ring 503 is fixedly connected to the inner wall of the cylinder 501.

[0029] It should be noted that the locking rod 502 can be inserted and moved in the middle of the limiting ring 503, the middle of the movable ring 504 and the outer side of the locking rod 502 are fixed by welding, and the locking rod 502 is inserted in the middle of the compression spring 505, which has a guiding function;

[0030] Specifically, the positioning member 4 includes a bolt 401, the ends of which are sequentially inserted and connected to the side of the sleeve rod 301 and the side of the extension ring 2. A nut 402 for fixing the sleeve rod 301 is provided at the insertion point of the bolt 401 and the extension ring 2.

[0031] It should be noted that a cylindrical hole for the insertion of a bolt 401 is opened on the side of the sleeve rod 301. The bolt 401 is set with a hexagonal socket and does not protrude from the side of the sleeve rod 301 to avoid affecting the arrangement and installation of multiple floor trough plates 1. A cylindrical groove for the insertion of a nut 402 is opened on the side of the extension ring 2. The inner wall of the cylindrical groove and the nut 402 are glued. The bolt 401 has no threads in the part of the cylindrical hole, which facilitates the rotation of the sleeve rod 301 around the bolt 401. The bolts 401 on both sides of the extension ring 2 are arranged at diagonal angles, which facilitates workers to lift the rotating component 3 diagonally.

[0032] During actual use, a rotating member 3 and a positioning member 4 for limiting the rotation of the rotating member 3 are symmetrically arranged on the outer side of the extension ring 2 at the end of the floor trough plate 1. After the sleeve rod 301 in the rotating member 3 is rotated by the bolt 401 in the positioning member 4, the construction personnel extend the rotating member 3 by pulling the movable rod 302, thereby facilitating the personnel to lift, transport and install the floor trough plate 1. At the same time, the rotating member 3 can also play the role of closing the installation gap between the floor trough plates 1.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
