[0021] Please refer to Figures 1-4, the present utility model provides a technical solution: a column foot connection device for connecting a glued laminated wood column to a concrete foundation, including a glued laminated wood column body 1. A connection card slot 12 is opened on the bottom surface of the glued laminated wood column body 1, and a group of annularly arranged positioning slots 15 are opened on the outer surface of the glued laminated wood column body 1. A connection card block 13 is clamped inside the connection card slot 12, which is convenient for clamping with the connection card slot 12, so that the glued laminated wood column body 1 is combined with the connection device. Its steps are simple and convenient. The bottom end of the connection card block 13 is connected to a support plate 2, and a group of positioning plates 6 adapted to the positioning slots 15 are connected to the outer surface of the connection card block 13, which is convenient for clamping with the positioning slots 15, thereby strengthening the connection effect between the glued laminated wood column body 1 and the connection device. Two symmetrically arranged threaded holes 11 are opened on the front surface of the glued laminated wood column body 1 and the right side surface of the glued laminated wood column body 1. A fixing bolt 3 is threadedly connected inside each threaded hole 11, which strengthens the firmness between the glued laminated wood column body 1 and the connection device, avoids loosening during use, and improves the practicability of the device. A fixing nut 5 is threadedly connected to the outer surface of each fixing bolt 3, which is convenient for using the anti-lock of the fixing nut 5 to strengthen the firmness between the glued laminated wood column body 1 and the connection device, and improves the use effect of the device.

[0022] Among them, a wear-resistant pad 10 is connected to the bottom surface of the support plate 2, and a group of equidistantly arranged anti-slip protrusions are connected to the bottom surface of the wear-resistant pad 10, which reduces the wear between the support plate 2 and the concrete foundation and extends the service life of the device.

[0023] Among them, four groups of reinforcing plates 9 are connected to the outer surface of the connection card block 13, and one side surface of each group of reinforcing plates 9 close to each other is connected to the outer surface of the positioning plate 6, which strengthens the firmness between the positioning plate 6 and the connection card block 13 and improves the practicability of the device.

[0024] Among them, an anti-slip plate 14 is connected to the outer surface of each positioning plate 6, and anti-slip protrusions are connected to the outer surface of each anti-slip plate 14, which strengthens the friction between the positioning plate 6 and the positioning slot 15 and enhances the firmness between the positioning plate 6 and the positioning slot 15.

[0025] Among them, two symmetrically arranged connection holes 7 are opened on the upper surface of the support plate 2, and anti-rust paint is applied to the inner wall of each connection hole 7, which is convenient for fixing the position of the support plate 2 and at the same time convenient for connecting the support plate 2 to the concrete foundation.

[0026] Among them, a group of annularly arranged support columns 4 are connected to the upper surface of the support plate 2, and the upper surface of each support column 4 is connected to the outer surface of the positioning plate 6, which provides a supporting effect for the positioning plate 6 and thus strengthens the firmness of the positioning plate 6.

[0027] Among them, a production label 8 is connected to the left side of the glulam column body 1, and a warning sign is connected to the left side of the production label 8, which is convenient for users to understand the product information of the device and improves the use effect of the device.

[0028] Working principle: During use, first, through the connection hole 7 and using expansion wires, the support plate 2 is connected to the concrete foundation to achieve the effect of fixing the position of the support plate 2. Then, the connection block 13 and the connection slot 12 are used for clamping connection, so that the glulam column body 1 is connected to the connection device. Next, the positioning plate 6 and the positioning slot 15 are combined to strengthen the connection effect between the glulam column body 1 and the connection device. Finally, the fixing bolt 3 is combined with the threaded hole 11 to achieve the effect of fixing between the connection device and the glulam column body 1. Subsequently, the fixing nut 5 is connected to the outer surface of the fixing bolt 3. Then, by the anti-locking of the fixing nut 5, the connection effect between the connection device and the glulam column body 1 can be strengthened.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
