Description

Technical Field

[0001] The utility model relates to the field of columns, in particular to a connection structure between a column and an inner lining member. Background Art

[0002] In order to reduce the material consumption of the one-piece column, the matching structure arranged on the inner wall of the column is eliminated, and then a lining piece is arranged at the end of the column, thereby ensuring that it has the same function while reducing the material consumption.

[0003] There are two traditional connection structures for fixing the lining to the end of the column:

[0004] The first method is to directly fix the lining member to the column by welding at both side ends of the lining member; the second method is as shown in publication number: CN221031809U, using fasteners such as bolts to fix the lining member to the column.

[0005] Both of these methods can only fasten the ends of the lining member, and the fitting surface between the lining member and the column is easily stressed and moves. Summary of the invention

[0006] In view of the deficiencies in the prior art, the utility model provides a connection structure between a column and an inner lining member, which can effectively solve the problems existing in the connection between the inner lining member and the column.

[0008] In the above technical solution, further, the column consists of a first long side and a second long side that are adjacently connected, and a first short side and a second short side that are connected to the other ends of the first long side and the second long side.

[0009] In the above technical solution, further, the first and second edges of the lining member are attached to the first long side and the second long side, and the ends of the first and second edges are against the first and second short sides.

[0010] In the above technical solution, further, the positioning rib is located on the inner wall of the column, and the positioning groove is located on the outer side surface of the lining member.

[0011] In the above technical solution, further, the positioning rib has the same shape as the positioning groove, which is an inverted trapezoidal shape.

[0012] In the above technical solution, further, two ends of the lining member are arc-shaped, and the weld is formed between the outer edge of the arc and the first short side and the second short side.

[0013] The beneficial effect of the utility model is that by arranging a plurality of groups of positioning ribs and positioning grooves, the contact surface of the lining part is further increased, and the function of preventing shaking and movement is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Reference Figure 1-7 As shown, a connection structure between a column and a lining member includes a column 1 and a lining member 2. The end of the column 1 is provided with a notch 3, and the lining member 2 is arranged on the opposite side of the notch 3. At least one group of positioning ribs 4 and positioning grooves 5 are arranged on the fitting surface of the column 1 and the lining member 2; the end of the lining member 3 abuts against the inner wall of the column 1, and a weld 12 is formed between the end of the lining member 3 and the column 1.

[0024] Among them, since the notch 3 is provided on the column 1, the length of the notch 3 is smaller than the width of the column 1, so that the end of the column 1 is composed of the adjacent first long side 6 and the second long side 7, and the first short side 8 and the second short side 9 connected to the first long side 6 and the second long side 7 and located at the other end.

[0025] The lining member 2 is L-shaped, and the two sides of the lining member 2 are respectively a first edge 10 and a second edge 11. When the lining member 2 is installed to the inner wall of the pillar 1, the first edge 10 and the second edge 11 are respectively attached to the first long side 6 and the second long side 7. At the same time, the first edge 10 and the second edge 11 of the lining member 2 are consistent with the width of the inner wall of the pillar 1, and the ends of the first edge 10 and the second edge 11 are against the inner walls of the first short side 8 and the second short side 9.

[0026] Due to the limited thickness of the column 1 and the lining member 2, although there is no need to overly restrict the installation positions of the positioning ribs 4 and the positioning grooves 5, it is preferred that the positioning ribs 4 are located on the inner wall of the column 1, the positioning grooves 5 are located on the outer surface of the lining member 2, a matching structure is provided on the first welt 10 and the second welt 11 of the lining member 2, a support member is provided at the inner corner of the lining member, and a hollow member is provided at both inner ends of the lining member 2. The installation positions of the positioning ribs 4 and the positioning grooves 5 can be located in the middle of the hollow member and the support member and relatively close to the hollow member (such as Figure 4 shown).

[0027] The positioning rib 4 and the positioning groove 5 have the same shape. Specifically, the positioning rib 4 and the positioning groove 5 have an inverted trapezoidal shape.

[0028] The shapes of the positioning rib 4 and the positioning groove 5 are not limited, and include the following embodiments:

[0029] Second embodiment ( Figure 6 ):The positioning rib 4 and the positioning groove 5 are super semicircular.

[0030] Third embodiment ( Figure 7 ):The positioning rib 4 and the positioning groove 5 are in an inverted convex shape.

[0031] Preferably, the positioning rib 4 and the positioning groove 5 can be provided as only one group, so as to ensure the firmness of the installation and limit the lining member 2 from shaking left and right and moving away from the column 1 .

[0032] Since there will be welding protrusions during welding, in order to ensure the aesthetic appearance, the end of the lining member 2 is set to be arc-shaped, the thickness of the lining member 2 is consistent with the inner length of the first short side 8 and the second short side 9, and a weld 12 is formed between the end of the lining member 2 and the first short side 8 and the second short side 9.

[0033] The working process of the utility model is as follows: the lining member 2 is inserted from top to bottom, the positioning rib 4 follows the positioning groove 5, the lining member 2 is embedded into the column 1, and the upper end surface of the lining member 2 is ensured to be flush with the upper end surface of the column 1, and the welding is performed at the weld 12, and the welding length is the length of the lining member 2.

[0034] The above is only an embodiment of the present invention and does not limit the present invention in any form. Simple modifications, equivalent changes or modifications made without departing from the technical solution of the present invention all fall within the protection scope of the present invention.
