Embodiment Construction
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0019] refer to Figure 1-4 , a reinforced connection structure inside a fire door, comprising an upper base plate 1 and a lower base plate 2, the bottom of the upper base plate 1 is provided with U-shaped grooves 7 at intervals, and the two ends of the U-shaped groove 7 are provided with card slots 3 along the length direction. There are multiple groups of door core panels 4 bonded at intervals in the length direction of the top of the lower substrate 2, and multiple sets of thermal deformation mechanisms 5 are arranged between any two groups of door core panels 4 along the width direction of the lower substrate 2, and the top ends of the thermal deformation mechanis...

The invention relates to the technical field of fireproof doors, and particularly relates to an internal reinforced connection structure of a fireproof door. The internal reinforced connection structure comprises an upper base plate and a lower base plate, wherein U-shaped grooves are formed in the bottom of the upper base plate at intervals, and clamping grooves are formed in the two end faces of the U-shaped grooves in the length direction in a penetrating mode. According to the internal reinforced connection structure of the fireproof door, door core plates are bonded to the top of the lower base plate, at the moment, a user can fix bases between the two sets of door core plates, the user can determine the number of the bases needing to be fixed according to the actual length and width of the fireproof door, after the door core plates are brushed with glue, the upper base plate covers the tops of the lower base plate and the door core plates, so that the upper base plate can be tightly connected with the lower base plate under the heating condition, the problem that the fireproof effect is influenced by the protrusion of the upper base plate or the lower base plate is avoided; and the higher the temperature is, the larger the deflection angle generated by a first metal sheet is, so that the larger the force of clamping blocks clamped in the clamping grooves is, and the connecting effect is better.
Description
technical field [0001] The invention relates to the technical field of fire doors, in particular to an internal reinforced connection structure of a fire door. Background technique [0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. In addition to the function of ordinary doors, it also has the function of preventing the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel. [0003] With the development of the fire door industry, national standards put forward strict requirements for non-toxic and harmless fireproof and heat insulation materials for the human body. The fire door core board inside the door puts forward higher requirements. This kind of fire door core board is a material that integrates fire protection, sound insulation and heat preservation, and is filled in steel fire doors a...
