Abstract

The utility model discloses a heat insulated aluminum door and window section structure, which comprises an outer frame and an inner frame. The heat insulated aluminum door and window section structure is characterized in that a hollow heat insulated strip is connected between the outer frame and the inner frame. After utilizing the above technical scheme, the heat insulated aluminum door and window section structure can save a frame structure in the prior art and save materials. In addition, by utilizing the single heat insulated strip structure, the heat insulated aluminum door and window section structure can realize double-edge rolling to a heat insulated rabbet and increase sealing property of sections of two edges of the heat insulated rabbet and the heat insulated strip.

Description

A kind of heat insulation aluminium door and window profile structure

Technical field:

The utility model relates to the aluminium door and window technical field, refers in particular to a kind of heat insulation aluminium door and window profile structure that is connected internal and external frame by single hollow heat insulating strip.

Background technology:

The interior outside aluminium extruded sections (as shown in Figure 1) of current heat insulation aluminium door and window section bar is to be connected by two solid heat insulating strips 01, this is (to comprise performances such as tension and shear strength) because the mechanical property of the solid heat insulating strip of wall scroll to be not enough to guarantee that section bar is connected the intensity index of back heat-insulation aluminum section, therefore must employing two syndeton.Because the heat-insulation aluminum section of two heat insulating strip 01 combined connecting structures is subjected to equipment and process limitation, wears the operation of bar and tooth punching operation for guaranteeing section bar, require to leave certain distance between two heat insulating strips 01, thereby it is bigger to make section bar wear bar joint face width.Must expend more aluminum alloy materials like this, increase cost of production; And constitute a cavity 02 by two heat insulating strips 01 and both sides section bar joint face, under the influence of indoor/outdoor temperature-difference, in this cavity 02, can produce heat radiation and, influence the heat preservation and insulation of door and window flow phenomenon.Simultaneously owing to be cavity body structure, heat insulating strip when mechanical stitch, can only roll extrusion on one side, sealing performance is difficult to assurance like this.

Summary of the invention:

The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, and a kind of economical with materials, with low cost, the aluminium door and window profile structure that improves heat preservation and insulation are provided.

For achieving the above object, the technical scheme that the utility model provides is: a kind of heat insulation aluminium door and window profile structure, include housing and inside casing, and it is characterized in that: between housing and inside casing, be connected with a hollow heat insulating strip.

After adopting technique scheme, because the mechanical property of hollow heat insulating strip is more winning than solid heat insulating strip, adopt wall scroll hollow heat insulating strip to connect between the aluminium extruded sections of medial and lateral and satisfy the connection index request, saved a heat insulating strip than traditional structure, simultaneously also can realize not having cavity body structure with the heat-insulation aluminum section that two solid heat insulating strips can't be realized, guaranteeing under the situation that heat-insulation aluminum section intensity does not descend that like this saving heat-insulation aluminum section material that can be by a relatively large margin reduces cost; And can form a cavity structure when having overcome by the combination of two heat insulating strips and both sides aluminium extruded sections, and the heat radiation that in this cavity, can produce and to flow phenomenon; Lower convexity is concordant with heat insulation notch on the hollow heat insulating strip, can block heat radiation and convection current between the heat insulation notch of both sides aluminium extruded sections; Thereby reduced the coefficient of heat insulation of heat insulation section, improved the heat preservation energy-saving performance of door and window.Simultaneously to have overcome two solid heat insulating strip heat-insulation aluminum section both sides can only be the single structure of band cavity aluminium extruded sections to single hollow heat-insulation aluminum section, do not have cavity body structure and do not have the chamber and have cavity body structure and both sides that cavity body structure is all arranged while can realize heat-insulation aluminum section.Improved the degree of freedom and the flexibility of door and window heat insulation section structure design greatly, more imagined space and selection for the designer, provide abundanter means approach the new product development of heat-insulating and energy-saving door and window and upgrading.

Description of drawings:

The structural representation of Fig. 1 prior art heat insulation section;

The structure chart of Fig. 2 the utility model aluminum window;

Fig. 3 is the A-A partial sectional view of Fig. 2.

Fig. 4 is the B-B partial sectional view of Fig. 2;

The heat insulation notch of Fig. 5 the utility model aluminum window is put on the structure chart before the roll extrusion behind the hollow heat insulating strip;

The heat insulation notch of Fig. 6 the utility model aluminum window is put on the structure chart after hollow heat insulating strip and the roll extrusion.

The specific embodiment:

Now 2～Fig. 6 elaborates the utility model in conjunction with the accompanying drawings:

This aluminium door and window profile structure includes housing 1 and inside casing 2, is connected with a hollow heat insulating strip 3 between housing 1 and the inside casing 2, and these hollow heat insulating strip 3 cross sections are hexagon.Design has housing 1 and 2 need of inside casing of wearing the bar notch to wear on the bar device fabrication line at the heat insulation section of routine, do not need other equipment input, by tooth punching on heat insulation notch (see figure 5), penetrate and heat insulation notch is carried out the roll extrusion combination behind the wall scroll hollow heat insulating strip and obtain required the utility model (see figure 6).

Hollow heat insulating strip 3 can overcome the inside mechanics shortcoming of the solid heat insulating strip of prior art, only just satisfy the bonding strength requirement of inside and outside both sides aluminium extruded sections with a hollow heat insulating strip, owing to self have the structure of lower convexity on cavity and its for hollow heat insulated 3, blocked the heat radiation of wearing the poor oral area position of bar and to flow phenomenon, its effect of heat insulation is also winning than solid heat insulating strip; Can carry out bilateral mechanical stitch between hollow heat insulating strip 3 of this programme and the aluminium in addition, improve the sealing performance between heat insulating strip and the aluminium.

The utility model modern design, with low cost and heat-insulating and energy-saving is effective, can finish at existing heat-insulation aluminum section device fabrication line, needn't drop into and transform by increase equipment, and cater to " energy-saving and emission-reduction " theme that current social is advocated, have good market prospects and society and economic benefit, be worth of widely use.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
