In construction projects, flatness control is a major core work in the quality and appearance of a building. Its importance is self-evident during the concrete pouring construction stage.

[0003] The existing open patent (publication number CN 220621091 U) discloses a floor deck concrete pouring elevation controller, including a laser leveler and a first vertical pipe, one end of the first vertical pipe is provided with a telescopic slot, a second vertical pipe is slidably installed in the telescopic slot through a moving block, a strip hole connected to the telescopic slot is provided on the surface of the first vertical pipe, a threaded rod is rotatably installed on the moving block, a top block with an isosceles trapezoidal cross section is threadedly sleeved on the threaded rod, support rods are symmetrically rotatably installed on the side of the moving block, two of the support rods are respectively in sliding contact with the two side surfaces of the top block, and a limiting component is provided on the moving block. The utility model abandons the traditional method of inserting reinforcement wires, and performs elevation control according to the scale difference on the laser leveler and the second vertical pipe through the mutual cooperation of the laser leveler, the first vertical pipe, the second vertical pipe, the threaded rod, the top block and the support rod, thereby reducing the waste of personnel and materials and improving accuracy and practicality.

[0004] The vertical pipe structure used in the above controller has poor overall structural stability during use, and the lifting and lowering adjustment method is also relatively inconvenient. Therefore, the utility model proposes a large-span floor elevation controller to improve the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model adopts an adjusting component as the base structure of the elevation component, and is used for adjusting the height and angle of the elevation component. Compared with the current sleeve-type elevation structure, the elevation controller is more convenient to use and carry, convenient for large span and multi-position use, and has high practical value. When the adjusting component is used, the handle is rotated, and the screw fixed relative to the handle rotates. The rotation of the screw will drive the beams to move closer or farther away from each other. During the movement of the beams, the angle between the swing arms connected to them changes. The supporting structure composed of several swing arms drives the top plate to rise or fall relative to the bottom plate, thereby completing the height adjustment of the elevation component. When not in use, the height of the top plate is adjusted to the lowest, which is convenient for carrying. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described 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 ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example

[0020] See also Figure 1-3 , as shown in the figure: This embodiment is a preferred implementation of the technical solution, a large-span floor elevation controller, including an elevation component 1 and an adjustment component 2 for adjusting the position of the elevation component 1, the elevation component 1 includes a scale plate 11, scale grooves 12 equidistantly penetrated and opened on the side of the scale plate 11, a movable block 13 fixed to the side of the scale plate 11 via a knob, and a pointer fixed to the side of the movable block 13; the adjustment component 2 includes a kit 22 arranged at the bottom of the scale plate 11, a base 23 movably connected to the kit 22, a top plate 21 fixed to the lower side of the base 23, a swing arm 210 movably arranged on the lower side of the top plate 21, a crossbeam 29 arranged at the connecting end of the swing arm 210, a screw 27 penetrating the middle of the crossbeam 29, a handle 28 fixed to the end of the screw 27, and a bottom plate 25 movably matched with the end of the swing arm 210 located below;

[0021] It should be noted that: in the large-span floor elevation controller involved in the present application, the adjustment component 2 is used as the base structure of the elevation component 1, and is used to adjust the height and angle of the elevation component 1. Compared with the current sleeve-type elevation structure, the elevation controller is more convenient to use and carry, convenient for large spans and multi-position use, and has high practical value. When the adjustment component 2 is used in practice, the handle 28 is rotated, and the screw 27 fixed relative to the handle 28 rotates. The rotation of the screw 27 will drive the cross beams 29 to move closer or farther away from each other. During the movement of the cross beam 29, the angle between the swing arms 210 connected to it changes. The support structure composed of several swing arms 210 drives the top plate 21 to rise or fall relative to the bottom plate 25, thereby completing the height adjustment of the elevation component 1, and when not in use, the height of the top plate 21 is adjusted to the lowest level for easy carrying.

[0022] Among them Figure 1 As shown, a slide groove is provided on the side of the scale plate 11, and the slide groove matches with the inner protrusion of the movable block 13; a slot is provided on the peripheral side of the kit 22, and the slot matches with the bottom of the scale plate 11;

[0023] It should be noted that the slide groove on the side of the scale plate 11 cooperates with the inner protrusion of the movable block 13 to limit the moving path of the movable block 13 so that it can only move in a straight line along the side of the scale plate 11. The kit 22 and the scale plate 11 are separate structures and are connected by plug-in, which is convenient for taking and placing the scale plate 11.

[0024] Among them Figure 2 As shown, a horizontal liquid level indicator 24 is fixed to the side of the base 23;

[0025] It should be noted that the horizontal liquid level display meter 24 is composed of a transparent material shell, provided with horizontal scale lines, and a liquid medium is arranged inside. Whether the base 23 is in a horizontal state is judged according to the coincidence degree between the liquid medium liquid surface and the horizontal scale lines.

[0026] The base 23 is recessed in the middle with an arc groove, which matches the sleeve 22, and the end of the sleeve 22 is movably connected to the side of the base 23 via a shaft; a positioning groove is provided at the side edge of the sleeve 22, and a positioning screw 26 is provided in the positioning groove, and the positioning screw 26 passes through the side of the base 23;

[0027] It should be noted that the inner wall of the arc groove fits with the circumference of the kit 22, and the end of the kit 22 is connected to the base 23 through the shaft, so that the kit 22 can rotate relative to the arc groove. When the kit 22 rotates, the scale plate 11 fixed relatively to the kit 22 rotates accordingly, which is used for vertical angle adjustment of the scale plate 11. The positioning groove opened on the side of the kit 22 is used to assist the positioning screw 26 to fix it. When in use, loosen the positioning screw 26, and the kit 22 loses its external restraint and can move relative to the base 23 for its angle adjustment. After the adjustment is completed, tighten the positioning screw 26. The inner end of the positioning screw 26 passes through the base 23 and contacts the inside of the arc groove of the kit 22, so that the kit 22 maintains a fixed relative position relative to the base 23.
