Background technology

Progress and development along with society, people more and more pay attention to the building energy-saving effect, China had also included building energy conservation in Eleventh-Five Year Plan as one of national legislation in recent years, building energy conservation will reach the heat insulation effect of regulation except requiring materials for wall, the door and window that needs often open and close is also had higher requirement, as advise that the door and window sash adopts the flat system of opening of small size, and employing heat insulation section structure, but for entering house door, then just can't reduce it by area, and have only the sealing effectiveness of strengthening between door leaf and the doorframe to prevent scattering and disappearing of energy.

The means that people adopt usually in the prior art are stifled: promptly constantly increase heat insulation filling, continuous reinforced door body structure, and between door leaf and doorframe the multiple-sealed structure of design, with this stop by every means outdoor and indoor between the circulation of cold and hot air and the conduction of heat.

Yet, expanding with heat and contract with cold is the intrinsic characteristic of all material, even the door leaf structure has high intensity again, the also distortion that can't stop door leaf to expand with heat and contract with cold and caused, especially (the northern area higher when indoor/outdoor temperature-difference surpasses more than 30 ℃ as latitude, outdoor is to be lower than subzero 15 ℃, and indoorly to keep 20 ℃ above freezing), the size on the outdoor and indoor two sides of door leaf will differ and reach more than the 1.9mm that (with the aluminium sheet door is example, the coefficient of thermal expansion and contraction of aluminium is 23.4 μ m/mK), thereby form mutual inconsistent flexural deformation inevitably, and between door leaf and doorframe the slit appears, cause outdoor and indoor between the circulation of cold and hot air and the conduction of heat, thereby cause huge energy loss and energy waste.

By Fig. 1, Fig. 2 as seen: A is the doorframe heat insulation section among the figure, B is the door leaf heat insulation section, G is PA66 glass nylon heat insulating strip (altogether everywhere), C is an outside metal door skin, and D is an indoor metal door skin, and E is the heat insulation filling in outside, F is the heat insulation filling in indoor, M is the outside weather strip, and N is the indoor weather strip, and bonding position is filled for thermal insulation by the K place.This structure has been to having carried out heat insulation processing (A, B are the door leaf heat insulation section) between the indoor and outdoors parts, thereby door leaf and doorframe all have heat insulation and preservation effect preferably.For door leaf, common connected mode is: indoor metal door skin D coheres with glue with door leaf heat insulation section B and heat insulation filling F simultaneously, E and F close as a whole, outside metal door skin C coheres with glue with the another side of door leaf heat insulation section B and heat insulation filling E, F simultaneously again, so makes door leaf become as a whole.

Summary of the invention

The utility model technical issues that need to address have provided a kind of door body structure of cold-and-heat resistent temperature deformation, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises: doorframe heat insulation section, door leaf heat insulation section, be placed in the doorframe and door leaf in heat insulating strip, outside weather strip, indoor weather strip, outside metal door skin, indoor metal door skin; Between described outside metal door skin and indoor metal door skin, also comprise: the heat insulation filling in outside, the heat insulation filling in indoor and door leaf heat insulation section; The heat insulation filling of the one side of described indoor metal door skin and door leaf heat insulation section and indoor is cohered with glue; The heat insulation filling of outside metal door skin and outside is cohered with glue; The another side of outside metal door skin and door leaf heat insulation section is a sliding connection structure; The heat insulation filling of heat insulation filling in described outside and indoor is an isolating construction.

Compared with prior art, the beneficial effects of the utility model are: even the door leaf temperature difference surpasses 40 ℃, the door leaf plane of this entering house door still can keep not diastrophic free state, thereby guarantees to still have excellent sealing performance between door leaf and the doorframe.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

By Fig. 1, Fig. 3 as seen: the utility model comprises: doorframe heat insulation section A, door leaf heat insulation section B, be placed in the doorframe and door leaf in heat insulating strip G, outside weather strip M, indoor weather strip, outside metal door skin C, indoor metal door skin D; Between described outside metal door skin C and indoor metal door skin D, also comprise: the heat insulation filling in outside E, indoor heat insulation filling F and door leaf heat insulation section B; The heat insulation filling of one side and the indoor F of described indoor metal door skin D and door leaf heat insulation section B coheres with glue; The heat insulation filling of outside metal door skin C and outside E coheres with glue; The another side of outside metal door skin C and door leaf heat insulation section B is sliding connection structure H; The heat insulation filling of described outside heat insulation filling E and indoor F is an isolating construction;

Being slidingly connected of the another side of described outside metal door skin C and door leaf heat insulation section B is to adopt the flute profile flanging to carry out plug-in connection in the contact position of the another side of outside metal door skin C and door leaf heat insulation section B;

Described plug-in connection is the groove place, surrounding of outside metal door skin C, along the in-plane of door leaf free extendable room is arranged.

Metal door skin in indoor coheres with glue with the heat insulation filling of door leaf heat insulation section and indoor simultaneously in the utility model, the heat insulation filling split in heat insulation filling in outside and indoor (not connecting mutually), outside metal door skin only coheres with glue with the heat insulation filling in outside, then cohere with the door leaf heat insulation section without glue, carry out plug-in connection but sentence the flute profile flanging at H, make door leaf existing as a whole with this, can guarantee that again outside metal door skin is at expanded by heating or catch a cold when shrinking, left and right sides slippage only takes place at the H place, and can not produce the active force of side direction to heat insulation section, door leaf is whole to produce flexural deformation because of the excessive temperature difference makes because of both sides door leaf face thereby avoided door leaf.To do local bonding processing between filling mainly be in order to strengthen the connection on two sides inside and outside the door leaf, can not influence expanding with heat and contract with cold of outside metal door skin again and the K place carries out thermal insulation.

Adopt the utility model, when the indoor and outdoor temperature difference surpasses more than 30 ℃, guarantee that still door leaf integral body does not occur bending and deformation.As being 20 ℃ with interior temperature, outside temperature is subzero 20 ℃ and is example: because outside temperature is very low, to cause dwindling (when when adopting aluminium sheet and with the interior temperature, being benchmark of outdoor metal decking size, its length is reduced into 1.9mm, its reduced width is 0.9mm), because what adopt around the outdoor metal decking is the flute profile plug-in connection (accompanying drawing H place) of inside flanging, it is the groove place, surrounding of outdoor metal decking, in-plane along door leaf has certain free extendable room (monolateral each about 2.5mm), therefore outdoor metal decking still is in the Free Transform state when meeting cold contraction, it is extra stressed that the fan frame of door leaf is produced, so though there is the temperature difference up to 40 ℃ its two sides, but concerning whole door leaf, there is not the internal force of distortion to exist, certainly door leaf just can not be out of shape yet, thereby has reached the effect of cold-and-heat resistent temperature deformation.
