Description
Technical Field
[0001] The utility model belongs to the technical field of household, and particularly relates to a heat-insulating bridge-breaking single-layer airtight steel-clad wood passive armored door. Background Art
[0002] At present, most of the existing thermal insulation passive armored doors adopt foreign processes and design drawings, and solve various problems of waterproofing, anti-corrosion and heat insulation in the form of aluminum-wood composite or steel-clad wood to achieve the effect. However, the metal materials are connected inside and outside, forming dot-shaped or linear heat bridges; most of the existing thermal insulation armored passive doors adopt multi-layer rigid rubber strips and multi-layer airtight design. The rubber strips are easy to age, and the use and replacement are complex, and the airtightness is poor.
[0003] Through the above analysis, the problems and defects existing in the prior art are as follows:
[0004] (1) At present, most of the existing thermal insulation passive armored doors adopt foreign processes and design drawings, and solve various problems of waterproofing, anti-corrosion and heat insulation in the form of aluminum-wood composite or steel-clad wood to achieve the effect. However, the metal materials are connected inside and outside, forming dot-shaped or linear heat bridges;
[0005] (2) At present, most of the existing thermal insulation armored passive doors adopt multi-layer rigid rubber strips and multi-layer airtight design. The rubber strips are easy to age, and the use and replacement are complex, and the airtightness is poor. Content of the Utility Model
[0006] Aiming at the problems existing in the prior art, the utility model provides a heat-insulating bridge-breaking single-layer airtight steel-clad wood passive armored door.
[0007] The utility model is realized as follows: A heat-insulating bridge-breaking single-layer airtight steel-clad wood passive armored door includes a door frame, a door leaf, door hinges, airtight rubber strips, and an intelligent door lock. The surfaces of the door frame and the door leaf are made of stainless steel panels. Airtight rubber strips are installed at the door seams. Door hinges are installed outdoors. The intelligent door lock is installed at one end away from the door hinges and is located in the middle of the door leaf in terms of height.
[0008] Further, the door frame is made of integral or spliced log squares, processed into the required thickness and depth of the door frame, and L-shaped joint grooves are opened. The thickness of the door frame is 6-12 cm, and the depth of the door frame completely wraps the door opening wall 5 and the insulation layer.
[0009] Further, the door leaf is made of integral or spliced log squares, with a thickness of 8-15 cm, and processed into the structural keel of the door leaf by tenon and mortise technology, which is in a day-shaped structure or a mu-shaped structure.
[0010] Further, wooden boards are installed on both the inner and outer sides of the middle empty part of the keel, and heat-insulating materials are filled in the middle of the wooden boards. The heat-insulating materials are xPs extruded boards or EPs polystyrene boards or polyurethane boards, or polyurethane foam materials are sprayed.
[0011] Further, an L-shaped installation groove for a multi-airbag airtight rubber strip with a width of 1 - 3 cm is formed around the entire perimeter of the front side of the door leaf frame.
[0012] Further, the door leaf is fixed to the door frame with three hinges with a load-bearing capacity of >50 kg, and the door can be outward-opening or inward-opening.
[0013] Combined with the above technical solutions and the solved technical problems, the advantages and positive effects of the technical solution to be protected by the present utility model are as follows:
[0014] First, the non-connected heat insulation bridge technology between the inner and outer steel plates of the armored door makes the heat insulation effect of the entrance door better and reduces heat loss.
[0015] The overall and continuous multi-airbag airtight rubber strip is both heat-insulating and airtight, and can be replaced as a whole, which is convenient and fast.
[0016] The single-layer airtight rubber ring design makes the overall door leaf structure simpler compared with the multi-layer sealing rubber strips, greatly reducing the production cost.
[0017] The steel protection plates wrapped on the door leaf and the door frame are divided into an indoor surface and an outdoor surface and are not connected to each other, which can effectively prevent heat from being transferred through the metal.
[0018] Selecting a single-layer, freely detachable integral airtight rubber ring can effectively solve a series of problems such as the aging of the rubber strip in the later stage, the deterioration of airtightness, the difficulty of replacement and maintenance, and the high production process and cost compared with the multi-layer airtight rubber strips with complex installation.
[0019] Illustrate in detail with examples:
[0020] For a standard entrance door opening with a width of 0.9 m, a height of 2.1 m, and a wall thickness of 24 cm, use a wooden square with a width of 200 mm and a thickness of 60 mm to cut an L-shaped groove with a depth of 2 mm. Along the inner corner of the L-shaped groove, at intervals of 1 cm, wrap and weld stainless steel plates on both the inner and outer sides.
[0021] After filling the insulation layer and sealing the two side boards on the door leaf skeleton with corresponding dimensions, after opening the airtight rubber strip card slots according to the above design, wrap and weld with 304 stainless steel, distinguish between the inner and outer sides outside the card slots, and retain a 2 cm heat insulation bridge isolation belt.
[0022] Second, all the inner and outer metals of the designed armored heat-insulating passive door are wrapped and welded with non-connected heat insulation bridges, with a wooden structure as the main support and stainless steel plates for auxiliary wrapping and support, which can reduce the flow and exchange of heat between the indoor and outdoor, greatly improve the heat insulation effect, and greatly reduce the temperature difference at each area position indoors, especially at the entrance door position, improving the comfort of the indoor environment.
[0023] The single-layer integral airtight rubber strip of this design can effectively meet the requirements of heat preservation and airtightness of the door leaf, while greatly saving the production and design complexity of multi-layer airtight rubber strips, being more convenient for later maintenance, easy to replace after the rubber strip ages, and facilitating the use and management by non-professional house owners.
[0024] Third, the technical solution of the present utility model fills the technical gaps in the domestic and international industries:
[0025] The present invention fills the gap in the domestic situation where the metal materials inside and outside the heat-insulating passive armor door are not completely isolated, resulting in the formation of dot-shaped or linear heat bridges in the door body itself. The present invention fills the gap in the domestic passive door design that requires multi-layer airtight rubber strips to meet the requirements of airtightness and heat preservation, and cannot adopt a single-layer airtight device that can be disassembled and replaced at will to maximize the convenience of use and management by non-professional house owners, and replace the aged rubber strip at any time to ensure the airtightness loss and heat preservation effect loss caused by the aging of the weather-resistant rubber strip over the years.
