Referring to fig. 2, a ground nail 21 is fixedly connected to the bottom of the mounting plate 2. The nail part of the ground nail 21 is a part entering the top surface, and the length of the top part is 12-16cm, in the embodiment, the length of the top part is 15 cm. The nail part is provided with a connecting hole 212, the connecting hole 212 is a circular through hole penetrating through the nail part of the ground nail 21, and the axis direction is vertical to the length direction of the nail part of the ground nail 21. The side wall of the ground nail 21 is also connected with a plurality of barbs 211. The barb 211 is the slope and is provided with the L type, and the bottom of barb 211 and the top fixed connection of ground nail 21, top to keeping away from the one side slope of nail portion. The barbs 211 are arranged at 4 positions on the ground nail 21 and are arranged in the circumferential direction of the nail part. The mounting panel 2 of this application can install when ground concrete is not dry through, with the bottom of mounting panel 2 towards concrete ground, vertical pushing down for the nail portion of ground nail 21 gets into ground, and the concrete can fill connecting hole 212 this moment, increases and decreases the joint strength of ground nail 21 and concrete ground. And barb 211 makes mounting panel 2 difficult upwards take place to break away from with ground after the installation gets into ground, increases the joint strength with ground, and then increases mounting panel 2's connection fastening degree. When installing mounting panel 2, can lay the one deck isolation layer in the bottom of mounting panel 2, the bottom and the concrete floor of a mounting panel 2 keep apart, reduce mounting panel 2 and concrete floor and take place to bond. The ground nail 21 is provided with 4, and 4 ground nails 21 are arranged in the bottom surface matrix of mounting panel 2 again. The top of the ground nail 21 can be welded to the bottom of the mounting plate 2 and can be integrally formed with the mounting plate 2.

Referring to fig. 2, the mounting plate 2 further defines a receiving groove 22. The accommodating groove 22 is a rectangular groove vertically formed downwards along the top surface of the mounting plate 2, and the length direction is perpendicular to the length direction of the mounting plate 2. The accommodating groove 22 is provided with two positions, and the two positions of the accommodating groove 22 are arranged at intervals along the width direction of the mounting plate 2. The support rod 221 is connected to the inside of the accommodation groove 22. The axial direction of the support rod 221 is parallel to the length direction of the receiving groove 22. One end of the support rod 221 is rotatably connected to the receiving groove 22. The supporting rod 221 can be rotated into the receiving groove 22, and can also be rotated until the supporting rod 221 is in a vertical state.
