Detailed Description
The technical solution of the present invention is described in further detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following description.
Referring to fig. 1, an embodiment of the present invention provides an integral splicing structure of a rectangular tube of a fire-resistant window, including a rectangular tube body, where the rectangular tube body includes a first splicing portion 1, a second splicing portion 2, and a bendable connecting portion, and the first splicing portion 1 and the second splicing portion 2 are connected together through the connecting portion; the butt joint ends of the first splicing part 1 and the second splicing part 2 are provided with inclined notches which can be mutually butted and spliced.
Referring to fig. 2, the first splicing portion 1 is provided with a first oblique notch 3, the second splicing portion 2 is provided with a second oblique notch 4, the first oblique notch 3 and the second oblique notch 4 are arranged oppositely, the cutting angle α is 45 degrees, and when the first oblique notch 3 and the second oblique notch 4 are not spliced, the included angle β is 90 degrees. The first splicing part 1 and the second splicing part 2 are connected into a whole through a connecting part, a reserved round angle 5 is arranged on the connecting part, and the bottom of the first inclined notch 3 is connected with the bottom of the second inclined notch 4 through the reserved round angle 5.
The utility model discloses a theory of operation and use as follows: a single rectangular pipe is used as a rectangular pipe body, and before splicing and blanking, a first bevel notch 3, a second bevel notch 4 and a reserved fillet 5 are respectively machined at a position to be spliced. When the frames are spliced in a butt joint mode, the connecting portion is bent by 90 degrees, as shown in fig. 3, the end face of the first oblique notch 3 is completely overlapped with the end face of the second oblique notch 4, and the first splicing portion 1 and the second splicing portion 2 are spliced in a butt joint mode.
