It can be understood that the hinge and the connecting plate can be connected to the door frame 2 by bolts as shown in fig. 2, or can be connected by other connection methods as needed, such as welding, integral molding, etc., which are not described herein again.
Specifically, the connection plates provided on the door frame 2 in the preferred embodiment include a first connection plate 201 and a second connection plate 202. The first connecting plate 201 is an L-shaped plate structure, one folded edge of the first connecting plate is parallel to the end surface of the door frame 2 and connected to the door frame 2, and the other folded edge is used for mounting the T-shaped bolt 5. Accordingly, the second connecting plate 202 has a horizontal plate-like structure, one end of which is connected to the door frame 2 and the other end of which is used for mounting the T-bolt 5. Obviously, the first connecting plate 201 and the second connecting plate 202 may be connected to the door frame 2 separately, or two connecting plates may be connected first, and then one of the connecting plates is connected to the door frame 2, as shown in fig. 2.
In actual installation, the door frame 2 is installed on the reinforced concrete partition wall 1 close to the door opening, the end face of the door frame is opposite to the end face of the reinforced concrete partition wall 1, and at the moment, the folded edge of the first connecting plate 201 for installing the T-shaped bolt 5 extends in the direction parallel to the inner wall face of the door opening and correspondingly extends to the front of the embedded channel 4 on the inner wall face of the door opening. Accordingly, one end of the second connection plate 202 facing away from the door frame 2 extends in a direction parallel to the surface of the reinforced concrete partition wall 1 and correspondingly extends in front of the pre-buried channel 4 on the surface of the reinforced concrete partition wall 1.
Further, the T-bolt 5 in the preferred embodiment is as shown in fig. 4 and 5, and includes a connecting portion 501 and a limiting portion 502, wherein the connecting portion 501 is a cylindrical structure, and the outer periphery of the connecting portion 501 is threaded for matching with a connecting nut; the limiting portion 502 is disposed at one end of the connecting portion 501 in a matching manner, and is in a strip-shaped structure, one end of the connecting portion 501 is connected to the middle of the limiting portion 502, and two ends of the limiting portion 502 protrude out of the periphery of the connecting portion 501 respectively, so as to form a "T-shaped" structure as shown in fig. 4.
