Abstract

Disclosed are a frame assembly structure of a wooden doors and windows and a corner assembly method. The window includes, at least, a window frame or a casement window frame mainly formed by joining adjacent profile frame strips via a corner assembler on adjacent connecting end surfaces. The connecting end surfaces of two adjacent profile frame strips are respectively configured to be cross sections of 0° to 180°. A positioning notch of the corner assembler is at least provided on the cross sections. Two half corner assemblers of the corner assemblers are respectively embedded and fixed into the positioning notches on the adjacent cross sections. The two half corner assemblers are connected by an intermediate fastening piece and a fastening bolt to form a complete corner assembler, and the two adjacent profile frame strips are connected tightly and fixedly. The frame assembly structure is easy to assemble.

Claims

1. A frame assembly structure of a wooden doors and windows, the wooden doors and windows comprising, at least, a window frame or a casement window frame formed by joining adjacent profile frame strips via a corner assembler on adjacent connecting end surfaces, wherein the connecting end surfaces of two adjacent profile frame strips are respectively configured to be cross sections of 0°

to 180°

;

a positioning notch of the corner assembler is at least provided on the cross sections of 0°

to 180° and

after adjacent profile frame strips are spliced completely, a space for accommodating an assembly-type corner assembler is formed at a spliced joint, wherein one half corner assembler is embedded and fixed into the positioning notch on the cross section of 0°

to 180°

of a profile frame strip, and an additional half corner assembler is embedded and fixed into the positioning notch on the cross section of 0°

to 180°

of the adjacent profile frame strip; and

two half corner assemblers are connected by an I-shaped fastening piece located in an intermediate position of the two half corner assemblers and a fastening bolt to form a complete assembly-type corner assembler, and the two adjacent profile frame strips are connected;

wherein the assembly-type corner assembler is formed by combining the two half corner assemblers identical in structure and shape, the I-shaped fastening piece and a fastening bolt;

each of the half corner assemblers is a fixing substrate with a fixing hole, wherein two symmetric side edges of the fixing substrate are vertically provided with a fixing side plate having a buckling edge at an upper end portion, separately, and a plug notch defined by two fixing side plates is provided above the fixing substrate; and

the fastening piece is an I-shaped fastening piece, and two symmetric edges of the I-shaped fastening piece just correspond to the plug notches on the fixing substrates, such that side edges of the I-shaped fastening piece are fixedly connected between the two half corner assemblers after being inserted from an end side.

2. The frame assembly structure of a wooden doors and windows as claimed in claim 1, wherein an end edge of the fixing substrate is provided with a vertical baffle, a half-round groove is provided at an upper end of the vertical baffle, and a hole allowing the fastening bolt to extend into the assembly-type corner assembler and to screw the I-shaped fastening piece is formed after the two half corner assemblers are connected together;

and a screw hole provided on a side end of the I-shaped fastening piece corresponds to the hole, and the screw hole is used for screwing the fastening bolt.

3. A corner assembly method for a wooden casement window, the corner assembly method assembles the wooden casement window by using the frame assembly structure of a wooden doors and windows as claimed in claim 1, wherein the corner assembly method for the wooden casement window comprises the following steps:

(a) processing a profile section needing to be corner-assembled to be a cross section of 0°

to 180°

, and milling a positioning notch for mounting a corner assembler and a round tenon rod hole in corner end surfaces of a corresponding profile;

(b) installing two half corner assemblers in positioning notches at cross sections of 0°

to 180°

of adjacent profile frame strips respectively, and fastening and connecting the half corner assemblers and end surfaces of the profile frame strips by means of a screw fastening piece;

(c) coating a round tenon rod of one of the profile frame strips with an end surface adhesive, and then inserting the round tenon rod into the round tenon rod hole; and

(d) during corner assembly, inserting a side edge of an I-shaped fastening piece into a plug notch of a fixing substrate in a corner assembler of a profile at one side, calibrating round tenon rods of two profile frame strips, round tenon rod holes and corner assemblers, fastening by means of fastening bolt extending out of holes in vertical baffles of the two half corner assemblers through rotation, and meanwhile, positioning and inserting the round tenon rods corresponding to profile corners.

4. The corner assembly method for a wooden window as claimed in claim U wherein in the step (a), after the respective cross sections of 0°

to 180°

of the two adjacent profile frame strips are respectively coated with dedicated structural adhesives, corner assembly connecting is performed; and

in the step (b), in order to achieve corner sealing tightness, the I-shaped fastening piece is more tightly fastened with the plug notches in the two half corner assemblers by adjusting the fastening bolt.
