Detailed Description

The following description will explain embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 3, the present invention includes a horizontal base, a vertical central shaft 1 is fixed at the upper end of the base, a horizontal rotary table 2 is sleeved at the upper end of the central shaft 1, a bearing is installed between the rotary table 2 and the central shaft 1, a horizontal fixing plate 3 is arranged above the rotary table 2, the fixing plate 3 is fixed with the central shaft 1, a plurality of notches are arranged around the fixing plate, a rotatable rotary wheel 4 is hinged in the notches, gear teeth are arranged around the rotary wheel 4, a vortex-shaped protruding strip 5 is arranged on the upper end surface of the rotary table 2, the protruding strip 5 is meshed with the gear teeth on the rotary wheel 4, and the rotary table 2 can drive the rotary wheel 4 to rotate through the protruding strip 5 when rotating; a rectangular cushion block 6 is fixed on one side of the rotating wheel 4, and the cushion block 6 can be driven to swing up and down when the rotating wheel 4 rotates.

In order to quickly install the device on a construction site, the base comprises a horizontal bottom plate 7, and a plurality of vertical sleeves 8 are fixed at the lower end of the bottom plate 7.

In order to quickly adjust the angle of the cushion block 6 on the construction site, a plurality of vertical connecting rods 9 are fixed at the lower end of the rotary table 2, and a handle 10 is fixed at the lower end of each connecting rod 9.

In order to ensure that the turntable 2 can bear the weight of the stair template and the later pouring, a tapered roller bearing is adopted between the turntable 2 and the rotating shaft.

In order to prevent the supporting strength of the rotating disc 2, the central shaft 1 is provided with an annular bulge, and the annular bulge is positioned below the rotating disc 2.

In order to prevent the base from shaking in the construction process, a compression screw is screwed on the side wall of the sleeve 8.

It is worth noting that this device not only can support the template of stair slope, under the special circumstances, also can support level or vertical template, and is specific, and rotatory carousel 2 makes runner 4 rotate, drives the cushion 6 and is in the level form back when runner 4, can be used for supporting horizontally template, and the reversal drives the cushion 6 and is in the vertical form back when runner 4, can support vertical template, and the usage is extensive, and is nimble convenient, and adaptability is strong.
