[0002] The keel system is a common structural system in the fields of construction and decoration, mainly used to provide support and fixation.

[0003] The existing metal keel connections ensure the structural stability and load-bearing capacity by welding or using special connectors. Once these connection methods are completed, they are relatively difficult to disassemble. At the same time, the reusable of materials cannot be achieved.

[0004] In order to improve the sustainable utilization of materials, it is necessary to improve the existing connection technology between keels to achieve simpler and faster installation and disassembly, while ensuring the structural stability and safety. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide a keel connection and installation structure and a keel system, which can achieve the detachable connection of two keels.

[0006] Based on this, an embodiment of the present utility model discloses a keel connection and installation structure for fixing a first keel and a second keel, including: a first fixing structure, which has a first clamping portion matching the first fixing groove of the first keel and a third clamping portion matching the third fixing groove of the second keel, wherein the extension lines of the first clamping portion and the third clamping portion intersect; a second fixing structure, which has a second clamping portion matching the second fixing groove of the first keel and a fourth clamping portion matching the fourth fixing groove of the second keel, wherein the extension lines of the second clamping portion and the fourth clamping portion intersect; a third fixing structure for fixing the first fixing structure and the second fixing structure.

Wherein, the bolt sequentially passes through the first through hole and the second through hole and is threadedly connected with the nut to fix the first fixing structure and the second fixing structure.

[0015] Adopting the above technical solution, the third fixing structure uses a nut and a bolt to fix the first fixing structure and the second fixing structure together. The bolt sequentially passes through the first through hole and the second through hole and is threadedly connected with the nut to fix the first fixing structure and the second fixing structure. On the one hand, the installation process is made more intuitive and simple, and even non-professionals can operate it relatively easily.
