[0002] The floor thickness controller is a tool often used in the process of concrete pouring construction of houses. A double-layer steel mesh is designed in the concrete pouring floor. A certain distance above the upper steel mesh is the upper end surface of the floor, and a distance of the lower steel mesh is the template. Most of the existing templates use wooden templates. The distance from the top surface of the wooden template to the upper end surface of the floor is the thickness of the floor. Some existing construction methods are to add a floor thickness controller or a horse stool made of cement between the upper and lower layers of steel mesh, and then start pouring concrete on the wooden template until it covers the upper steel bars.
[0003] The floor thickness required for different styles of floors is also different, but the thickness of most existing floor controllers is always fixed, which results in a controller of a certain height being able to be used only on a floor of one style, thereby reducing the practicality of the controller. When there is no corresponding controller for floor construction, the corresponding controller needs to be replaced before construction can continue, which seriously affects the efficiency of floor construction and reduces the speed of floor construction.

DETAILED DESCRIPTION
[0017] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1 and Figure 2 , the utility model provides a technical solution:
[0019] A floor thickness controller includes a support 101 of a cone structure, wherein the support 101 has a first side surface 1011 and a second side surface 1012, wherein the first side surface 1011 and the second side surface 1012 are adjacent to each other and perpendicular to each other; two first placement blocks 201 distributed vertically are arranged on the first side surface 1011, and two second placement blocks 202 distributed vertically are arranged on the second side surface 1012. Since a double-layer steel mesh is designed in a concrete cast floor slab, and transverse steel bars and vertical steel bars arranged vertically to each other are present in the steel mesh, the support 101 is designed to have such a structure, and is used in conjunction with four placement blocks, so that it is convenient to place in the steel mesh. Specifically, the first placement block 201 and the second placement block 202 near the top of the support 101 are convenient for placing the transverse steel bars and vertical steel bars of the upper steel mesh; the first placement block 201 and the second placement block 202 near the bottom of the support 101 are convenient for placing the transverse steel bars and vertical steel bars of the lower steel mesh. The water stop plate 301 installed in the middle of the bracket 101 can prolong the time for free water to flow to the bottom of the floor during the setting process of the mud, so that the free water can be fully absorbed by the concrete and evaporated by hydration.
[0020] In order to improve the practicability of the floor thickness controller so that the same floor thickness controller can be suitable for different floor thicknesses, a lifting and adjusting mechanism is installed on the top of the bracket 101 to adjust the height of the placement platform 401.
[0021] Specifically, the lifting and adjusting mechanism includes a box body 501 installed on the top of the bracket 101, and a rack 502, a gear 503 and a self-locking mechanism all located in the box body 501. The rack 502 is slidably connected to the box body 501, and the sliding direction of the rack 502 is the same as the vertical direction. The top of the rack 502 extends out of the box body 501 and is connected to the placement platform 401; the gear 503 is rotatably connected to the box body 501 and meshes with the rack 502; the self-locking mechanism cooperates with the rack 502, so that the rack 502 cannot fall naturally after rising. The box body 501 protects the rack 502, the gear 503 and the self-locking mechanism. The rack 502 and the box body 501 can be connected by a dovetail structure, so that the rack 502 does not separate from the box body 501 during the sliding process on the box body 501. A control shaft can be rotatably connected to the box body 501 , one end of which extends into the box body 501 and is connected to the gear 503 , and the other end extends out of the box body 501 , so that the staff can rotate the control shaft to control the rotation of the gear 503 .
[0022] Specifically, the self-locking mechanism includes a locking claw of a Z-shaped structure and a first spring 504, the locking claw includes a rod 1 505, a rod 2 506 and a rod 3 507, the rod 1 505 and the rod 3 507 are connected through the rod 2 506, and the free end of the rod 1 505 can mesh with the rack 502. In this embodiment, the rod 1 505, the rod 2 506 and the rod 3 507 are integrally formed. A rotating shaft 508 is hinged at the connection between rod 2 506 and rod 3 507, and the rotating shaft 508 is hinged to the box body 501; the distance between the projection point of the end of rod 2 506 close to rod 1 505 in the horizontal direction and the projection point of the end of rod 2 506 close to rod 3 507 in the horizontal direction is greater than 0; one end of the first spring 504 is connected to rod 3 507, and the other end is connected to the box body 501, and the first spring 504 is always in a compressed state or a stretched state, so that rod 1 505 is always in a meshing state with the rack 502; a through hole 509 is opened on the box body 501, and the diameter of the through hole 509 is larger than the radial cross-sectional size of rod 3 507, and rod 3 507 extends out of the through hole 509.
[0023] The self-locking mechanism is designed as this structure, which uses the gravity of the locking claw and the elastic force of the spring to achieve its self-locking function. Figure 2 As shown, since the rod 2 506 is in an inclined state, the rod 1 505 is installed at the free end of the rod 2 506, and the center of gravity of the rod 1 505 and the rod 2 506 as a whole is located on the left side of the rotating shaft 508, so the rod 1 505 and the rod 2 506 have a tendency to rotate counterclockwise around the central axis of the rotating shaft 508 under the action of their own weight; Figure 2The second spring 601 is in a compressed state, and rod three 507 tends to rotate counterclockwise around the central axis of the rotating shaft 508 under the action of the elastic force of the second spring 601. Rod one 505 and rod two 506 also tend to rotate counterclockwise around the central axis of the rotating shaft 508 under the action of rod three 507. Therefore, this design makes the free end of rod one 505 always in a meshing state with the rack 502.
[0024] like Figure 2 As shown, when the placement platform 401 needs to be raised, the gear 503 is rotated clockwise, the rack 502 rises so that the teeth of the rack 502 squeeze the free end of the rod 1 505. The structure of the self-locking mechanism allows this squeezing force to make the rod 2 506 rotate clockwise around the central axis of the rotating shaft 508. Therefore, during the rising process of the rack 502, the free ends of the rod 1 505 will be separated from the corresponding slots respectively, so as not to affect the rising of the rack 502. When the rack 502 rises to a suitable height, the gear 503 stops rotating, and the rack 502 has a tendency to fall under the action of its own gravity. However, due to the existence of the self-locking mechanism, the free end of rod 1 505 is always in meshing state with rack 502. The squeezing force of the teeth of rack 502 on the free end of rod 1 505 makes rod 2 506 tend to rotate counterclockwise around the central axis of rotating shaft 508, but cannot rotate clockwise around the central axis of rotating shaft 508. Therefore, rack 502 cannot fall under the restriction of the self-locking mechanism.
[0025] When the height of the placement platform 401 needs to be lowered, the free end of the third rod 507 is pressed downward, so that the third rod 507 rotates clockwise around the central axis of the rotating shaft 508, and the second rod 506 is driven by the third rod 507 to rotate clockwise around the central axis of the rotating shaft 508, and the second rod 506 drives the first rod 505 to separate from the rack 502, so that the rack 502 can fall. When the rack 502 falls to a suitable position, the third rod 507 is not pressed, and the free end of the first rod 505 is re-engaged with the rack 502.
[0026] In some implementations of this embodiment, in order to facilitate a tighter engagement between the rack 502 and the rod 505 to improve the stability of the connection, a second spring 601 is also installed at the bottom of the rack 502, and the other end of the second spring 601 is connected to the inner bottom of the box body 501, and the extension direction of the second spring 601 is the same as the sliding direction of the rack 502.
[0027] In some implementations of this embodiment, a deformable sealing ring 701 is further installed in the through hole 509, and the deformable sealing ring 701 is in contact with the outer circumference of the rod 3 507. The deformable sealing ring 701 seals the through hole 509 without affecting the rotation of the rod 3 507, so that the liquid cannot enter the through hole 509 and flow into the box body 501.
[0028] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
