Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

Example 1: the utility model provides a reinforced structure for purlin tenon, as shown in fig. 1, including new tenon 200, metal sheet 300, staple bolt 400 and fourth of the twelve earthly branches mouth 110, new tenon 200 pegs graft on old purlin 100, and metal sheet 300 fixed mounting connects new tenon 200 and old purlin 100 on new tenon 200 and old purlin 100, and the staple bolt 400 cover is established outside new tenon 200 and old purlin 100, and all staple bolts 400 are located between the metal strip both ends.

The new tenon 200 is provided with a mortise and tenon 210, and the mortise and tenon 210 is inserted in the vertical direction. Wherein the metal strips are located above the old purlins 100 and the new tenons 200, thereby concealing the metal strips.

Referring to fig. 2, the mortise 110 is arranged at one end of the old purlin 100, and the new tenon 200 is provided with a plug-in part 220 at one end opposite to the mortise 210, and the plug-in part 220 is matched with the mortise 110.

The mortise opening 110 is arranged in a line shape, two sides of the mortise opening penetrate through the side walls of the old purline 100, the insertion part 220 is in a line shape, and the length direction of the insertion part 220 is the same as the insertion direction of the mortise and tenon joint 210. Through the mortise 110 in the vertical direction, only the splicing trace is left at the bottom, so that the splicing trace between the new tenon 200 and the old purline 100 is smaller.

Wherein, the metal strip is connected with the old purlin 100 and the new tenon 200 through the connecting bolt 310.

With reference to fig. 1 and fig. 2, the anchor ear 400 is sleeved on the old purlin 100 and the new tenon 200, and at least two anchor ears 400 are provided, and two are taken as an example in this embodiment.

The hoop 400 is made of wood material, and the metal strip is located in the hoop 400.

In this embodiment, the purlin has a circular structure, but is not limited to a circular structure, and may be applied to any shape of purlin structure.

Example 2: as shown in fig. 3, the difference from embodiment 1 is that the mortise 110 is a jack provided at the end of the old purlin 100, the cross section of the jack is polygonal, and a regular quadrilateral is adopted in this embodiment.

Compared with the embodiment 1, the embodiment has the advantages that only one gap is formed in splicing between the new tenon 200 and the old purline 100, the hiding effect is better, and meanwhile, the connecting strength between the new tenon 200 and the old purline 100 is also better.

Example 3: as shown in fig. 4, the difference from embodiment 1 is that the mortise opening 110 is arranged in a line shape, two sides of the mortise opening penetrate through the side wall of the old purlin 100, the insertion part 220 is in a line shape, and the length direction of the insertion part 220 is perpendicular to the insertion direction of the mortise 210.

Compared with the embodiment 1, the mortise 110 in the embodiment 1 uses the vertical straight-line arrangement, while the embodiment uses the horizontal straight-line arrangement, the splicing trace between the new tenon 200 and the old purline 100 is larger, but the connection strength between the new tenon 200 and the old purline 100 is high.

Example 4: as shown in fig. 5, the difference from example 1 is that the mortise 110 penetrates through the end and one side of the old purlin 100, and the metal bar is located above the side opening of the mortise 110.

The joint between the new tenon 200 and the old purlin 100 has only one gap, and the hiding effect is the same as that of the embodiment 2.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent laws within the scope of the present invention.
