5.2.1 Structure
5.2.1.1 The right-angle intersection between the frame and the upper and lower frames of wooden doors and windows can adopt straight and dense patterns or other structural forms. For the edges of door and window frames with moldings, the exposed surface structure is generally a 45° cut straight and dense pattern. The corners of hardwood doors and windows generally adopt a 45° cut. 5.2.1.2 The joints of the upper, middle and lower braces of wooden door panels and the side braces, and the joints of the upper, middle and lower braces of window panels and bright window panels and the side braces can adopt straight and dense patterns or other structural forms. The four corners of the door frame of plywood doors and molded doors and the parts and components can adopt a sample structure, or they can be connected with nails.
5.2.1.3 For those adopting the vertebral joint structure, glue should be applied to the sample head and sample hole wall respectively during assembly, and the glue should be evenly applied. For the transparent samples with exposed parts and components, wooden wedges should be added after assembly. 5.2.1.4 The exposed sample eye structure and the diagonal lines must be tight, without missing samples and empty heads, and the lines must be interlaced. The gap at the structure of I (high) products shall not exceed 0.2mm, the number of strips shall not exceed 1/4 of the total structure of a frame or a leaf; I (medium) and II (general) products shall not exceed 0.4mm, the number of strips shall not exceed 1/4 of the total structure, and there shall be no residual glue marks. The maximum gap between the middle sample shoulder of the straight dense sample shall not exceed 1mm.
5.2.1.5 If the plywood door and molded door are made of artificial board (medium density board and particle board) to make the door frame, the joint between the upper frame and the frame is generally 45° cut and interlocked, the joint should be tight, and the installation connection of the internal metal connectors should be tight and reliable. The fixed side cylinder board and the corner of the face and the middle main board of the door frame should be firmly glued, and the retractable side should be tightly matched with the main board, and a gap of about 2mm should be left at the bottom of the main board sample groove. 5.2.2 Joining and gluing of parts
5.2.2.1 The upper and lower frames, side frames of wooden door and window frames, the upper and lower braces and side braces of wooden door panels can be glued together to the width. The thickness of I (medium) grade and straight (general) grade products can also be glued together. 5.2.2.2 If the core board of the wooden door is made of wood, it must be made of plywood. The core board of the interior door can also be made of plywood. Other veneer artificial boards can also be used for II (medium) grade and II (general) grade interior doors, and the base material grade is specified in Table 3. 5.2, 2.3 The double-cut stems used for wooden door and window frames can also be glued, but the stems must be embedded in the 5mm deep groove of the frame material and glued and nailed firmly (the stems of the rotating window can be glued with 8

Glue flat nails).
5.2.2.4 The glue joints should be tight. 1 (high) grade door and window parts are not allowed to have obvious glue seams, The widest part of the local glue seam of the parts of Grade I (Medium) and (General) shall not exceed 0.2mm, and the length shall not exceed 1/4.
5.2.2.5All parts of Grade I (Medium) and Grade III (General) doors and windows, as well as the parts of all levels of plywood doors and molded door tires (including the upper, lower and side supports of the door tires) can be lengthened by finger-joining of short materials. The finger-joined materials of the parts of plywood doors and molded door tires shall not be less than 200mm in length (except at both ends), and the finger-joined materials of the parts of other levels of doors and windows shall not be less than 300mm in length (except at both ends). The technical requirements and quality of finger-joining must comply with the provisions of GB/T11954. 5.2.2.6The frames of Grade II (Medium) and Heavy (General) interior doors, the upper, middle and lower supports can be made of soft miscellaneous wood (such as pine, etc.) ), the surface is made of planed hardwood veneer glued together; the glued parts should be flat and firm, and there should be no defects such as debonding, ripples, indentations, etc. 5.2.2.7 For various plywood doors, molded doors or door frames made of decorative artificial boards, the glue between the surface decorative materials and the base material, or the glue between the decorative artificial boards and the door frame should be flat and firm; there should be no debonding and delamination, and there should be no local blistering, dents and obvious hard edges, indentations or ripples, sand penetration and other defects. 5.2.2.8 The type and thickness of artificial boards or molded door skins used on both sides of the door leaves of various plywood doors and molded doors must be consistent. If plywood is used, the tree species should also be the same. The artificial boards used for II (medium) grade and sub (general) grade plywood doors are allowed to be spliced from two pieces in the length direction (the interface should be at the door The lower part or the upper and lower part of the glass opening), the joints should be tight and flat.
5.2.2.9 The edging of plywood door panels
For plywood door panels with wooden strips, glue should be applied to the door edges and strips respectively and then nailed together. The joints should be tight and there should be no traces left. The door edges sealed with veneer or other decorative materials should be flat and firm; the corners should be naturally connected, the joints should be tight, and there should be no defects such as breakage and cracking.
The inlay lines of paneled doors should also be glued and nailed together, and the joints should be tight. 5.2.2.10
5.2.3 Surface roughness
5.2.3.1 The surface of finished wooden doors and windows and parts and components shall not have any defects after sanding or polishing.
