Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an assembly structure of a door frame to be installed in an opening of a building such as a house or a building.

[Problems to be Solved by Conventional Techniques and Inventions] Conventionally, this type of door frame has been constructed such that a frame-formed door frame is brought into the field and assembled, but the frame-formed door frame is bulky. However, it is not easy to pack the product, and it requires a large space, which incurs high transportation costs and requires a large storage space in the factory or on-site.

Therefore, it is proposed that the door frame is assembled on site, but in this case, as shown in FIG. 4, the projecting insertion piece is inserted through the insertion hole formed in the vertical frame and the locking pin is inserted. It is proposed that the insertion piece be retained by using the so as to assemble it. However, in such a case, there is a drawback that the door frame may be distorted due to an excessive or insufficient amount of hitting of the stop pin, which makes it difficult to perform on-site assembly with high accuracy.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a door frame assembly structure capable of eliminating these drawbacks. A door frame formed by framing a horizontal frame and left and right vertical frames, wherein a projecting insertion piece is inserted into the insertion hole formed in the vertical frame, and the insertion piece is formed in the insertion piece. When the stop pin is forcibly fitted into the pin hole of the above and is assembled by retaining, the stop pin substantially coincides with the edge of the vertical frame when the stop pin is fitted into the dimensioned fitting amount state. The head thus set is formed in a flat plate shape so as to close the edge of the vertical frame.

According to the present invention, the door frame can be assembled on site, and the amount of fitting of the locking pin can be made accurate.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a door frame, and the door frame 1 is formed by left and right vertical frames 2 and 2 and upper and lower horizontal frames 3 and 3. Insertion hole 2a at the upper and lower ends
Are drilled respectively. On the other hand, insertion pieces 3a for inserting through the insertion holes 2a are formed at the left and right ends of the horizontal frames 3 and 3, respectively.

The door frame 1 is dimensioned by inserting the insertion piece 3a into the insertion hole 2a and forcibly inserting the wedge-shaped stop pin (taper pin) 4 into the pin hole 3b formed in the insertion piece 3a. The lock pin 4 is integrally provided with a head portion 4a, and the head portion 4a is forcibly fitted by being hit with a tool such as a hammer. . The head 4a has an upper end formed in a flat plate shape, and by hitting the head 4a until the head 4a substantially coincides with the upper end edge of the vertical frame 2, the stop pin 4 is dimensioned so as to be fitted properly. It is set. Moreover, in this state, the head
4a is set so as to close the upper end of the vertical frame 2.

Reference numeral 5 denotes a door body. The door body 5 is configured such that face plates 7 are applied to the front and rear surfaces of a substantially bow-shaped door liner 6, but the face plate 7 is located outside the liner abutting portion. It is folded back at a position projecting toward one side, and further bent itself along the outer surface of the liner 6, and the end portion is fitted into the central concave portion 6a, whereby the side surface portion of the door body 5 is A concave groove-shaped media groove 5a is formed. Further, a concave groove 7a formed by punching or the like is formed on the inner side of the folded back portion of the face plate 7. On the other hand, the media member 8 for closing the media groove 5a is formed by a substantially U-shaped plate material, and the convex portions 8a are formed on both side surfaces thereof so as to correspond to the concave grooves 7a. The side edge of the door body 5 can be assembled by fitting the media member 8 into the media groove 5a by pushing the convex portion 8a into the concave groove 7a for fitting. .

In the embodiment of the present invention constructed as described above, the door frame 1 is assembled by tapping the stop pin 4 into the pin hole 3b with the horizontal frame insertion piece 3a inserted into the vertical frame insertion hole 2a. However, in this case, the stop pin 4 is accurately dimensioned by hitting and fitting the head 4a until the head 4a is substantially at the same position as the end edge of the vertical frame 2. The door frames 1 are fitted together in the assembled state, whereby the frame of the door frame 1 is formed.

Moreover, in this case, since the head 4a has a flat plate shape and closes the edge of the vertical frame, it is not necessary to previously provide a mortar flow stopper on the edge of the vertical frame 2, and the head 4a can be used as it is. It can be used as a stop piece and can be used for multiple purposes. By the way, when building the door frame 1 on the frame, mortar may be poured into the outer peripheral side of the door frame, and at this time, the mortar flow stop should be a vertical frame edge (especially the lower edge).
Therefore, the head 4a is also used for this mortar flow stop.

In the embodiment of the present invention, the door frame 1
Can be easily assembled on-site, but in that case,
It is possible to eliminate the problem that the precision of the frame dimension is not good due to insufficient hitting of the locking pin 4, and the door frame 1 with high precision can be eliminated.
Can be easily assembled on site.

Moreover, since the head portion 4a can be effectively used as it is as a mortar flow stop plate for the vertical frame 2, a step of separately providing these members to the vertical frame 2 by welding or the like becomes unnecessary, and workability can be improved. At the same time, dual use of members is achieved.

[Advantages] In short, since the present invention is constructed as described above, the horizontal frame insertion piece is inserted into the vertical frame insertion hole, and the door frame is fixed on the site by retaining it with the retaining pin. Although it can be assembled with, the retaining pin is forcibly fitted to the position where the head part is almost aligned with the edge of the vertical frame, so that the retaining pin can be fitted securely in the dimension. It is possible to make sure that the combination is accurate, and it is easy to perform accurate frame assembly even at the site.

Moreover, since the stop pin head is formed in a flat plate shape and closes the edge of the vertical frame, it is not necessary to previously provide a mortar flow stop piece on the edge of the vertical frame, and the head can be used as it is. It can be used as a stop piece and can be used for multiple purposes.
