Description

Technical Field

[0001] The utility model relates to the technical field of thickness controllers, in particular to a pavement concrete thickness controller for construction. Background Art

[0002] At present, in order to meet the different usage needs of the construction industry, researchers in related fields are also continuously improving the concrete thickness controller. For example, the patent document with application number 202023212485.0 proposes "a self-made concrete floor thickness controller, which includes a thickness controller body: the top of the thickness controller body is provided with a concrete pouring cavity, the bottom of the front and rear sides of the thickness controller body are provided with lower steel bar grooves, the top of the front and rear sides of the thickness controller body are provided with upper steel bar grooves, the interior of the thickness controller body is provided with two active cavities, the front and rear sides of the top of the thickness controller body are provided with grooves, and the A driving mechanism is arranged on one side of the bottom of the inner cavity of the movable cavity, a moving mechanism is arranged in the inner cavity of the movable cavity, limiting mechanisms are arranged on the top and bottom of the inner cavity of the movable cavity, and a positioning mechanism is arranged on one side of the moving mechanism". After specific implementation, "the controller is installed on the floor formwork of corresponding thickness, so that the steel bars enter the inner cavity of the lower steel bar groove and the upper steel bar groove respectively, and then the knob is turned so that the knob finally tightens the steel bars in the inner cavity of the upper steel bar groove to complete the installation, thus achieving the purpose of easy installation. The self-made concrete floor thickness controller has the advantage of easy installation, and there is no need to use marking lines for control, which improves the accuracy of floor thickness control".

Although from a theoretical perspective, the above patent design can be realized, it is too difficult to actually make, and its practicality is greatly limited. Utility Model Content

[0028] Working principle:

[0029] Embodiment 1

[0030] A plurality of steel bars are respectively passed through the clamping groove 2 at the top of the controller body 1 and the clamping groove 2 at the bottom of the controller body 1. During the installation of the steel bars in the clamping groove 2, the clamping sleeve 51 inside the clamping groove 2 is adapted and contacted under the elastic deformation of the folded spring sheet 52.

[0031] At the same time, the T-threaded rod 6 slides synchronously with the clamping sleeve 51 inside the give-way slot 4. After the steel bar is stably installed in the clamping slot 2, the nut 7 on the T-threaded rod 6 is screwed so that the nut 7 fits tightly against the surface of the controller body 1 to lock and limit the clamping sleeve 51.

[0032] Embodiment 2

[0033] For the assembly of the whole device, the elastic clamping member 5 can be firstly mounted inside the storage slot 3, and then one end of the folded spring sheet 52 is welded and fixed to the inner wall of the storage slot 3, and then the movable cover plate 8 is mounted on the stepped open structure at the top of the storage slot 3 and detachably mounted using screws;

[0034] The nut 7 is threadedly connected to the surface of the T-threaded rod 6 and moved toward the other end of the T-threaded rod 6. Then, one end of the T-threaded rod 6 passes through the yielding groove 4 and is threadedly connected to the second threaded hole on the clamping sleeve 51 to complete the assembly of the T-threaded rod 6 and the clamping sleeve 51. At this point, the entire device can be used satisfactorily.
