[0010] Preferably, a slotted opening is arranged on the CLT board, and the width of the tenon is equal to the width of the slotted opening.

[0011] Preferably, the length of the slotted opening is twice the length of the tenon or the mortise.

[0012] Preferably, the tenon and the mortise are in a dovetail shape.

[0013] Technical effects and advantages of the present utility model: The fixing screws are respectively installed in the mounting holes provided on the tenon and mortise groove, and one end of the fixing screw is fixed in the opening groove provided on the CLT board. Thus, the two CLT boards can be quickly connected through the tenon and mortise joint. Through the counterbore, the screw head of the fixing screw is placed, and the screw head is embedded into the interior of the counterbore without being exposed, which is not only convenient for installation, but also increases the aesthetic degree. Moreover, through the tenon and mortise joint method of the tenon and mortise groove, it is convenient for disassembly and reuse, and the installation is convenient.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] The present utility model provides a hidden wooden structure CLT hardware connector as shown in Figures 1-3 , including a CLT board 1 and a connection body 2. The connection body 2 includes a tenon 3 and a mortise groove 4. The tenon 3 and the mortise groove 4 are tenon-mortise jointed. The tenon 3 and the mortise groove 4 are respectively located on the outer walls of opposite sides of the CLT board 1. Fixing screws 5 are provided on both the tenon 3 and the mortise groove 4. The tenon 3 and the mortise groove 4 are in a dovetail shape. The fixing screws 5 are respectively installed in the mounting holes 6 provided on the tenon 3 and the mortise groove 4, and one end of the fixing screw 5 is fixed in the opening groove provided on the CLT board 1. Thus, the two CLT boards 1 can be quickly connected through the tenon 3 and the mortise groove 4. Through the counterbore 7, the screw head of the fixing screw 5 is placed, and the screw head is embedded into the interior of the counterbore 7 without being exposed, which is not only convenient for installation, but also increases the aesthetic degree. Moreover, through the tenon-mortise joint method of the tenon 3 and the mortise groove 4, it is convenient for disassembly and reuse, and the installation is convenient.

[0020] Specifically, mounting holes 6 are provided on the tenon 3 and the mortise 4. The fixing screw 5 passes through the mounting hole 6, and one end of the fixing screw 5 is threadedly connected to the CLT board 1. A counterbore 7 is provided at one end of the mounting hole 6, and the depth of the counterbore 7 is greater than the thickness of the screw head on the fixing screw 5. A slot opening 8 is provided on the CLT board 1, and the width of the tenon 3 is equal to the width of the slot opening 8. Through the fixing screw 5 provided on the tenon 3 and the mortise 4, the position of the screw head of the fixing bolt is located in the counterbore 7 after installation. The screw head of the fixing bolt is hidden by the counterbore 7 so that there is no resistance during tenoning. The slot opening 8 with the same width as the tenon 3 and the mortise 4 hides the tenon 3 and the mortise 4 of the fixing opening into the slot opening 8. The two CLT boards 1 are connected by the fixing bolts on the tenon 3 and the mortise 4 respectively. As the tenon 3 and the mortise 4 are tenoned, the two CLT boards 1 are connected. Through the tenons 3 and mortises 4 respectively connected to both sides of the CLT board 1, the mutual connection of multiple CLT boards 1 is realized, greatly improving the installation efficiency. Installation can be carried out in the factory after the CLT board 1 is processed, which can ensure the on-site installation accuracy. Moreover, the tenoning connection method can be disassembled and reused, improving the utilization efficiency.

[0021] Specifically, the length and width of the tenon 3 are equal to those of the mortise 4. The length of the slot opening 8 is twice that of the tenon 3 or the mortise 4. When the tenon 3 is installed with the mortise 4, the tenon 3 first aligns with the inner wall on the upper side of the slot opening 8 and then slides downward to the inner wall on the bottom side of the slot opening 8. The tenon 3 and the mortise 4 in the shape of a dovetail realize the fixation on both left and right sides during connection, and during disassembly, the CLT board 1 can be lifted upward.

[0022] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
