[0021] The utility model is further described below in conjunction with the accompanying drawings.

[0022] like Figures 1 to 5 As shown:

[0023] like Figure 1As shown, the utility model is a height adjustment device for assembling a steel grid frame, comprising a steel ball support 1 and a tire frame base 4. An adjusting cylinder 5 is arranged in the middle of the tire frame base 4, an adjusting screw rod 2 is arranged inside the adjusting cylinder 5, the upper part of the adjusting screw rod 2 extends out of the adjusting cylinder 5 and is fastened and installed by an adjusting nut 3, so that the adjusting screw rod 2 and the adjusting cylinder 5 are fixedly installed, a steel ball support 1 is arranged on the top of the adjusting screw rod 2, the adjusting screw rod 2 and the steel ball support 1 are fastened and installed by a nut 6, and an assembly steel ball is placed on the top of the steel ball support 1.

[0024] Specifically: the overall node assembly is supported by the tire frame base 4, the middle part of the tire frame base 4 is threadedly connected to the adjusting screw 2 through the adjusting tube 5, the top of the adjusting screw 2 extends out of the adjusting tube 5, and the height of the extending adjusting screw 2 is realized according to the on-site construction requirements. After the height is determined, the adjusting screw 2 is fastened and installed on the adjusting tube 5 through the adjusting nut 3. A steel ball support 1 is provided on the top of the adjusting screw 2, and is fastened and installed on the bottom of the steel ball support 1 through a nut 6. The top support of the steel ball support 1 supports the assembly steel ball; the up and down adjustment and self-locking of the steel ball position are realized through this assembly. The device has a unique structure, is simple and flexible to manufacture, and has strong versatility and interchangeability. It effectively solves the problem of accurate positioning and adjustment of the grid ball node, and greatly reduces the labor intensity of construction personnel while shortening the construction period.

[0025] At least in one embodiment, the adjusting screw rod 2 and the steel ball support 1 are installed in the first way: the top of the adjusting screw rod 2 is threadedly installed with the bottom of the steel ball support 1, and is threadedly fastened with a nut 6.

[0026] For this installation method, after the height of the adjusting screw rod 2 is adjusted, the adjusting screw rod 2 and the steel ball support 1 are first threadedly installed, and then the nut 6 is threadedly fastened for installation. The advantage is that the steel ball support 1 and the adjusting screw rod 2 are installed separately, which is conducive to the flexible support assembly of the steel ball during on-site construction, avoids multiple height adjustments, and can complete the support assembly and installation in one time.

[0027] At least in one embodiment, the second installation method of the adjusting screw 2 and the steel ball support 1 is: a nut 6 is fixedly provided at the bottom of the steel ball support 1, and the nut 6 is threadedly fastened to the top of the adjusting screw 2, so that the steel ball support 1 and the nut 6 are installed as a whole, and the nut 6 is then threadedly installed with the adjusting screw 2, thereby improving the construction and installation efficiency and improving the installation and fastening characteristics of the steel ball support 1 and the adjusting screw 2.

[0028] In at least one embodiment, Figure 5 As shown, in order to achieve stable support of the tire frame base 4, the tire frame base 4 includes a supporting base plate 11 and at least four fixed columns 12. An adjusting cylinder 5 is vertically arranged in the middle of the supporting base plate 11.
