In order to reduce the displacement between the fixing device 10 and the connecting device 20 and the instability of subsequent paving, the first fixing hole 12, the second fixing hole 13 and the third fixing hole 22 are arranged on the mounting groove 11 and the mounting head 21 respectively, the first fixing hole 12, the second fixing hole 13 and the third fixing hole 22 penetrating through the mounting groove 11 and the mounting head 21 are provided with a limiting device 30, which is helpful to increase the stability of the connection and facilitate the subsequent paving operation. When the installation is completed, the limiting device 30 can be removed, and the connecting device 20 and the fixing device 10 are separated, which ensures the stability of the installation and also increases the convenience of use. In order to ensure that the fixing device 10 and the connecting device 20 can be closely connected with the bamboo plywood and reduce the risk of sliding, the connecting device 20 and the fixing device 10 are provided with an expansion head 14, which closely connects and fixes the connecting device 20 and the fixing device 10 with the subsequent device, increases the tightness and stability of the connection, and is helpful to better paving. The fixing device 10 and the connecting device 20 are both steel products, which is helpful to ensure the mechanical strength of the device.

The area of the connection between the conical limiting device 30 and the fixing device 10 is small, and only a small displacement is needed to complete the disassembly, which is helpful to increase the convenience of the disassembly and installation process. The efficiency is increased and the cost is reduced. In order to increase the connection stability of the fixing device 10 and the connecting device 20 and ensure the simplicity of the installation process, the limiting device 30 is set as a rivet, and the installation process usually does not need special tools or equipment. At the same time, the rivet has high durability and corrosion resistance, which helps to prolong the service life of the limiting device and reduce the maintenance cost.

[0046] In order to detect whether the fixing device 10 and the connecting device 20 are in the same horizontal plane, and ensure the flatness of subsequent paving, a detection plate 15 is arranged on the bottom surface of the fixing device 10. If the measurement plate 15 shows that the fixing device 10 and the connecting device 20 are in the same horizontal plane, the next paving is carried out; if the measurement plate 15 shows that the fixing device 10 and the connecting device 20 are not in the same horizontal plane, the relative positions of the fixing device 10 and the connecting device 20 need to be further adjusted so that they are in the same horizontal height, and then the next paving is carried out. The detection plate 15 performs quality detection in advance for the flat assembly of the subsequent bamboo plywood, which is conducive to improving the quality of the subsequent processed products and reducing the unevenness. The fixing device 10 and the detection plate 15 are connected and fixed in a hinged manner, which increases the flexibility of the detection plate 15 and also ensures the stability of the connection.
