Further, in this embodiment, there are a plurality of leveling teeth 404, and the plurality of leveling teeth 404 are sequentially arranged along the central axis direction of the adjusting rod 401; by arranging the leveling teeth 404, one leveling tooth 404 is clamped between every two adjacent kerbs in the construction process, and after the kerbs are installed for a period of time, the leveling teeth 404 clamped between the two adjacent kerbs are taken out, so that the consistency of the seam width between the two adjacent kerbs is improved; meanwhile, the construction efficiency of the installation of the kerbstone is improved, and the construction time is saved.

The thickness of the leveling teeth 404 is selected according to the width of the seam between two adjacent kerbs in the design drawing, and the leveling teeth 404 have the functions of leveling the upper end face of the mortar layer and controlling the width of the seam between the kerbs. Two adjacent curb stones are installed, the upper end face of the mortar layer is strickled to the level of the bottom elevation of the curb stone to be installed, and then the two opposite sides of the two curb stones are tightly attached to the two opposite sides of the leveling teeth 404 to be placed, so that the width consistency of the seam between the two adjacent curb stones is improved, and the attractiveness of the curb stones is further improved.

The use process of the multifunctional control device 1 provided by the embodiment is as follows: according to the intended installation of the curb in the construction site, firstly, the stabilizing component 50 is adjusted, the sleeve 501 rotates around the central axis of the second support rod 20, the support is driven to rotate, the bottom ends of the horizontal rod 504 and the fixing seat 5041 are both attached to the ground, and then the fastening bolt 502 is screwed; secondly, adjusting the straightness control mechanism 30, firstly sliding the connecting rod 301 along the central axis direction of the first supporting rod 10/the second supporting rod 20, sliding the laser 302 along the length direction of the connecting rod 301 after the connecting rod 301 slides to a certain position, so that a light beam irradiated by the laser 302 is overlapped with an edge line at the bottom end of the kerbstone to be installed, and then screwing the fastening screw 304 to avoid the sliding of the connecting rod 301; adjusting the gradient control mechanism 40 again, sliding the adjusting rod 401 along the central axis direction of the first support rod 10 to enable the adjusting rod 401 to be flush with the bottom end of the to-be-installed curb, adjusting the adjusting bolt to enable the central axis of the adjusting rod 401 to be parallel to the gradient of the road, and screwing the fixing bolt 405; finally, installing the curb; the leveling ruler 404 slides repeatedly along the axis direction of the adjusting rod 401, so that the upper end face of the mortar layer is leveled to the level of the bottom elevation of the curb to be installed, the curb is installed, and when two adjacent curbs are installed, two opposite sides of the two curbs are attached to two opposite sides of the leveling ruler 404, so that the width of the seam between the two adjacent curbs is consistent.

The multifunctional control device 1 provided by the embodiment comprises a first support rod 10, a second support rod 20, a straightness control mechanism 30 and a gradient control mechanism 40; the first supporting rod 10 and the second supporting rod 20 are arranged at intervals along the extending direction of the straightness control mechanism, the first end of the straightness control mechanism 30 is connected with the first supporting rod 10, the second end of the straightness control mechanism 30 is connected with the second supporting rod 20, the straightness control mechanism 30 can be adjusted along the central axis direction of the first supporting rod 10 and the second supporting rod 20, and the straightness control mechanism 30 is used for controlling the straightness of the kerbstone; one end of the slope control mechanism 40 is connected with the first support rod 10, the slope control mechanism 40 can be adjusted along the central axis direction of the first support rod 10, and the slope control mechanism 40 is used for determining that the bottom elevation of the kerbstone is consistent with the slope of the road; so set up, improved the straightness accuracy in same direction as of curb line type, simultaneously, also improved the difference in height between two adjacent curb and the uniformity of seam width, improved the aesthetic property of curb.

The multifunctional control device 1 provided by the invention has the following advantages: the device has simple structure, easy manufacture and convenient operation.
