The disclosure relates to a frame assembly structure of a wooden casement window, and falls within the technical field of building windows.
At the present stage, China is strongly advocating a policy of energy conservation and emission reduction, and building energy conservation, serving as an important component in the field of overall energy conservation, plays an important role increasingly. Window energy conservation occupies about 40% to 50% of the building energy conservation, and improvement of the window energy conservation is improvement of the building energy conservation. Due to a better heat preservation performance, a wooden window is widely applied to energy conservation buildings.
A frame assembly mode of a traditional wooden casement window is groove tenon joining, an overall process is complicated, and a fitting precision requirement is high. The quantity of processing devices used in groove tenon processing and corner assembly processes is large, the cost investment is high, and the accuracy is difficult to control. When corners are assembled by using 45°, corner assembly is achieved by using a round tenon rod and dovetail tenon corner assembly process. However, because a dovetail tenon is made of nylon and due to the own structure thereof, the overall strength after corner assembly is unlikely to achieve groove tenon corner assembly strength. Moreover, a phenomenon of non-tight sealing of some joints as time goes by will be caused, thereby generating phenomena of water seepage, mildewing and the like.
The disclosure is directed to a frame assembly structure of a wooden doors and windows, which is simple in structure, convenient to install, firm to use, and capable of effectively ensuring the joining strength of corners and the corner assembly sealing property, increasing convenience of frame assembly and improving the production efficiency, in order to overcome the defects in the prior art.
The objective of the disclosure is fulfilled by means of the technical solution as follows. According to a frame assembly structure of a wooden doors and windows, the wooden doors and windows comprises, 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 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 the other 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. The two half corner assemblers are connected by an intermediate fastening piece and fastening bolt to form a complete assembly-type corner assembler, and the two adjacent profile frame strips are connected tightly and fixedly.
Preferably, the assembly-type corner assembler is formed by combining two half corner assemblers identical in structure and shape, an 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, so as to form plug notches above the fixing substrate, the fastening piece is an I-shaped fastening piece, wherein 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.
Preferably, 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.
