Detailed Description

The utility model discloses a description about combination door position, except special explanation, all regard the operating condition that the door frame was installed in the door opening as the benchmark.

Fig. 1 is a schematic single-side sectional view of the combination door of the present invention. The door leaf in the closed state is only partially shown in the figure, but the sideline is not yet fully installed. Referring to fig. 1, a sectional door 10 includes a door frame 1 and a door leaf 2. The door leaf 2 rests against the door stop 13 in the closed position. The doorframe 1 comprises a doorframe main body 12 and two sidelines 11 which are positioned at the front side and the rear side of the doorframe main body and have the same structure. The door frame body 12 includes an inner layer 123 made of a medium density fiberboard, an outer layer 121 made of a medium density fiberboard, and a core layer 122 sandwiched therebetween. The structure of the door 2 is symmetrical in the front-rear direction, and the structure on the rear side will be explained. On the rear side, i.e. the upper side in the figure, the two outermost layers of the door leaf 2, i.e. the frame layer 21 and the main body outer layer 22, are made of medium density fiberboard. A step 23 is provided at the inner end of the frame layer 21. The step 23 is lowered from the outer surface of the frame layer 21 to the outer surface of the body outer layer 22. The step 23 is provided with a door pressing line 3.

The border wire 11 comprises a peripheral portion 112 and a plug portion 111 provided at one end of said peripheral portion. The peripheral portion 112 serves to seal and decorate the door frame in the circumferential direction of the door frame main body 12. The inserting portion 111 is mainly used for connection of the sideline 11 and the door frame body 12. The peripheral portion 112 is provided at the other end thereof near the bottom surface with a projection 1121 projecting toward the center of the thickness of the door frame. The protrusion 1121 and the corresponding plug section 111 form a recess 1122 in the bottom of the peripheral portion 112. When the side line 11 is mounted on the door frame body 12 on the wall surface, a few uneven portions of the wall surface below the side line are received in the grooves 1122, and only the protruding portion 1121 contacts the wall. The problem that the joints are exposed due to loose contact caused by uneven wall under the condition that the bottoms of the sidelines are straight is avoided. Therefore, the sideline is closer to the wall body after being installed, and is more attractive visually. The protrusion 1121 is preferably protruded by about 2 to 5 mm relative to its neighboring portion, so as to ensure that the edge is installed tightly, and also ensure that the gap at the bottom of the edge is not too large to affect the using effect of the edge.

The sideline 11 is made of polyethylene wood plastic single material through extrusion molding. The interior of which may be provided with a plurality of longitudinally extending spaces 1123. Therefore, the wall thickness of the sideline can be integrally uniform, and the strength of the section can be increased. Preferably, the lateral width w1 of the border is 4 to 10 cm, which ensures visual aesthetics.

Referring to fig. 2, the bottom surface of the door holding wire 3 is a stepped surface 31 adapted to the stepped portion 23, and the front surface thereof is a specially-shaped curved surface 32.

Similarly to the sidelines 11, the door leaf press line 3 is also made of a polyethylene wood plastic single material by extrusion molding. Inside which a number of spaces 33 are present. Its transverse width w2 (fig. 1) is 2 to 5 cm. This ensures visual aesthetics.

It should be noted that the illustration in fig. 1 applies to both the vertical and the transverse edges of the door frame.
