Description

Technical Field

[0001] The utility model relates to the technical field of fireproof door frames, in particular to a hidden-frame super-large fireproof door. Background Art

[0002] A fire door refers to a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. Before installing the fire door, it is first necessary to connect and install the door frame of the fire door and the finishing material on the outer wall of the door opening. The existing super-large fire doors are all installed with exposed frames. After installation, the upper frame and vertical frame of the fire door are on the same plane as the finishing material, which has poor concealment and affects the appearance.

[0003] After searching, the Chinese patent application number CN202221498457.6 discloses a quickly installed fire door frame, including a wall, a first door frame assembly and two second door frame assemblies, and openings are provided on the left and right sides of the first door frame assembly. However, since the above technical solution does not provide a corresponding structure that can hide the door frame and install it on the side of the finishing material, the fire door frame will still be exposed on the side of the wall finishing, thereby affecting the overall aesthetics of the building wall. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a hidden frame super-large fireproof door.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The hidden frame extra-large fireproof door includes a door leaf, an upper frame and a vertical frame. The outer wall of the upper frame is fixed with a hanging plate, the outer wall of the hanging plate is plugged with an L-shaped metal limit buckle angle, the outer wall of the vertical frame is plugged with a T-shaped metal buckle angle, and the L-shaped metal limit buckle angle and the outer wall of the L-shaped metal limit buckle angle are respectively plugged with metal wall panel finishes.

[0007] As a further solution of the present invention: the L-shaped metal limiting buckle angle and the outer wall of the L-shaped metal limiting buckle angle are respectively connected with stone wall panel facings.

[0008] As a further solution of the present invention: an N-shaped metal pull plate is fixed to the inner wall of the upper frame.

[0009] As a further solution of the present invention: a butt plate is fixed to the outer wall of one side of the N-shaped metal pull plate, and the butt plate is inserted into the outer wall of one side of the hanging plate.

[0010] As a further solution of the present invention: the upper frame, the N-shaped metal pull plate and the outer wall of the vertical frame are respectively provided with a corrosion-resistant coating.

[0011] As a further solution of the present invention: the door leaf, the L-shaped metal limit buckle angle and the outer wall of the T-shaped metal buckle angle are respectively provided with a corrosion-resistant coating.

[0012] The beneficial effects of the utility model are:

[0013] 1. This concealed frame super-large fire door combines the material and thickness of the currently applicable finishing materials, changes the original exposed frame installation to a concealed frame installation, and by changing the processing technology, shortening the cross-sectional dimensions of the upper frame and the vertical frame, so that they are closely integrated with the finishing materials, and changing the exposed frame to a concealed frame, the super-large fire door becomes a truly "invisible" door, realizing a truly "fully hidden" structure, effectively improving the applicability and decorativeness of the super-large fire door product.

[0014] 2. The N-shaped metal pull plate is used for the fixed installation of the upper frame, so that the upper frame can form a complete closed workpiece, ensuring the stability and firmness of the frame, and facilitating the subsequent installation and welding of the opening. At the same time, the entire abutment plate on one side of the N-shaped metal pull plate can effectively support the hanging plate, thereby improving the supporting effect of the hanging plate on the decorative surface installed on one side of the L-shaped metal limit buckle.

[0026] Example 1

[0027] Hidden frame oversized fire door, such as Figure 1-6 As shown, it includes a door leaf 1, an upper frame 2 and a vertical frame 8. The outer wall of the upper frame 2 is fixed with a hanging plate 4, the outer wall of the hanging plate 4 is plugged with an L-shaped metal limit buckle 5, the outer wall of the vertical frame 8 is plugged with a T-shaped metal buckle 9, and the outer walls of the L-shaped metal limit buckle 5 and the L-shaped metal limit buckle 5 are respectively plugged with metal wall panel facings 6;

[0028] The L-shaped metal limiting buckle angle 5 and the outer wall of the L-shaped metal limiting buckle angle 5 are respectively plugged with stone wall panel facings 7.

[0029] The L-shaped metal limit buckle angle 5 is used for the installation of the upper frame 2, and is used in conjunction with wall finishing materials such as stone, rock slabs, and metal plates. Before installation, fix the L-shaped metal limit buckle angle 5 to the end of the finishing material, and then hang it on the hanging plate 4 on one side of the upper frame 2 to complete the limiting installation of the finishing materials around the fire door. The T-shaped metal buckle angle 9 is used for the installation of the vertical frame 8, and is used in conjunction with wall finishing materials such as stone, rock slabs, and metal plates. Before installation, fix the T-shaped metal buckle angle 9 to the outer mouth of the vertical frame 8, and cooperate with the stone, rock slab, and metal finishing limiting installation, so that the upper frame 2 and the vertical frame 8 can be stably fixed and limited on the inside of the finishing. The L-shaped metal limit buckle angle 5 and the T-shaped metal buckle angle 9 can ensure that there is a fixed gap between the wall finishing material and the door leaf 1, ensuring that the door leaf 1 can be opened freely, thereby achieving the best hidden decorative effect of the upper frame 2 and the vertical frame 8 while the installation protection of the door leaf 1 is not affected in any way.

[0030] This concealed frame super-large fire door combines the material and thickness of the currently applicable finishing materials, changes the original exposed frame installation into a concealed frame installation, and by changing the processing technology, shortening the cross-sectional dimensions of the upper frame and vertical frame, so that they are closely integrated with the finishing materials, and changing the exposed frame into a concealed frame, the super-large fire door becomes a truly "invisible" door, realizing a truly "fully hidden" structure, and effectively improving the applicability and decorativeness of the super-large fire door product.

[0031] like Figure 1-3 As shown, an N-shaped metal pull plate 3 is fixed to the inner wall of the upper frame 2 ; a support plate 10 is fixed to the outer wall of one side of the N-shaped metal pull plate 3 , and the support plate 10 is plugged into the outer wall of one side of the hanging plate 4 .

[0032] The N-shaped metal pull plate 3 is used for fixing and installing the upper frame 2, so that the upper frame 2 can form a complete closed workpiece, ensuring the stability and firmness of the frame, and facilitating the later installation and welding of the opening. At the same time, the abutment plate 10 on one side of the N-shaped metal pull plate 3 can effectively support the hanging plate 4 as a whole, thereby improving the supporting effect of the hanging plate 4 on the decorative surface installed on one side of the L-shaped metal limit buckle 5.

[0033] The outer walls of the upper frame 2, N-shaped metal pull plate 3 and vertical frame 8 are respectively provided with corrosion-resistant coatings;

[0034] The outer walls of the door leaf 1, the L-shaped metal limit buckle angle 5 and the T-shaped metal buckle angle 9 are respectively provided with corrosion-resistant coatings.

[0035] Working principle: The L-shaped metal limit buckle angle 5 is used for the installation of the upper frame 2, and is used in conjunction with wall finishing materials such as stone, rock slabs, and metal plates. Before installation, fix the L-shaped metal limit buckle angle 5 to the end of the finishing material, and then hang it on the hanging plate 4 on one side of the upper frame 2 to complete the limiting installation of the finishing materials around the fire door. The T-shaped metal buckle angle 9 is used for the installation of the vertical frame 8, and is used in conjunction with wall finishing materials such as stone, rock slabs, and metal plates. Before installation, fix the T-shaped metal buckle angle 9 to the outer mouth of the vertical frame 8, and cooperate with the stone, rock slab, and metal finishing to limit the installation. The upper frame 2 and the vertical frame 8 can be stably fixed and limited on the inside of the finishing. The L-shaped metal limit buckle angle 5 and the T-shaped metal buckle angle 9 can ensure that there is a fixed gap between the wall finishing material and the door leaf 1, ensuring that the door leaf 1 can be opened freely, thereby achieving the best hidden decorative effect of the upper frame 2 and the vertical frame 8 while the installation protection of the door leaf 1 is not affected in any way.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
