Fig. 2 is a cross sectional view of a middle corner of a fire door leaf according to the present invention.
Detailed Description
The present invention will be further described with reference to the following drawings and specific examples, but the following examples are by no means limiting the present invention.
As shown in fig. 1 and 2, one side of the fire door leaf 1 provided by the present invention is hinged to the fire door frame 3 disposed in the door opening of the wall 2, and includes a leaf frame, a door panel 4, a steel sub-frame and an inorganic heat insulating material 8; the door frame is composed of door frame strips 5 which are vertical and horizontal, and door frame strips 5 which are vertical left and right, and the end parts of the adjacent door frame strips 5 are connected together by using an angle bracket 10; the edges of the two door panels 4 are respectively arranged on the front end surface and the rear end surface of the fan frame, and four side surfaces of each door panel 4 are respectively provided with an inserting groove along the length direction of the side surface; the exposed side surfaces of the door leaf frame strips 5 are respectively provided with a steel auxiliary frame strip 6, the four steel auxiliary frame strips 6 form a steel auxiliary frame, and the edges of two sides of each steel auxiliary frame strip 6 are bent inwards to form an inserting edge which can be respectively inserted into the inserting grooves on the two door plates 4; the steel auxiliary frame strips 6 are connected with the door leaf frame strips 5 by screws, and the two end parts of the steel auxiliary frame strips 6 respectively penetrate through the door leaf frame strips 5 by screws to be connected with the corner connectors 10; the inorganic heat insulation material 8 is filled in the space enclosed by the fan frame and the two door panels 4.
When no threshold exists, the fireproof door leaf 1 further comprises decorative edges 7 respectively arranged on the top surface and the left and right side surfaces of the fireproof door leaf, and fireproof expansion strips are arranged on the bottom surface of the fireproof door leaf; when there is a threshold, the fireproof door leaf 1 further includes decorative borders 7 respectively installed on the top surface, the bottom surface, and the left and right side surfaces.
The door leaf frame strip 5 is made of aluminum alloy section bars and has a hollow structure.
A first fireproof expansion strip 11 is arranged in the cavity of the corner connector 10.
And a second fireproof expansion strip 9 is arranged in the cavity of the door leaf frame strip 5.
The door plate 4 is made of any one of a calcium silicate board and a glass magnesium board.
And a high-temperature-resistant fireproof flame-retardant adhesive bonding layer is arranged between the decorative edge 7 and the steel auxiliary frame strip 6.
And the front end surface and the rear end surface between the edges of the two door panels 4 and the fan frame are provided with adhesive layers.
Will now the utility model provides a fire door leaf 1's theory of operation as follows:
the steel sub-frame 6 has a high melting point and therefore better fire resistance. The fireproof expansion strip is non-combustible after expansion, has poor thermal conductivity, and can well protect the door leaf frame strip 5 made of aluminum alloy section bars from being burnt out by flame. When a fire disaster happens, the first fireproof expansion strips 11 in the cavities of the corner connectors 10 in the fireproof door leaf 1 expand to be full of the cavities of the corner connectors 10, the second fireproof expansion strips 9 in the cavities of the door frame strips 5 expand to be full of the cavities of the door frame strips 5, the corner connectors 10 and the door frame strips 5 are protected after the fireproof expansion strips expand, and the fireproof time of the corner connectors 10 and the door frame strips 5 is prolonged. The steel auxiliary frame strip 6 tightly clamps the two door panels 4, so that the door panels 4 are not separated, and the steel auxiliary frame strip 6 can still keep the integrity of the door frame after the door leaf frame strip 5 is burnt out. In this way the fire protection time of the fire door leaf 1 is greatly extended.
