Abstract
The utility model relates to a high-strength energy-saving thermal-insulation metal section bar desired by doors and windows of construction engineering, comprising metal section bar 1. The utility model is characterized in that heat insulation slots are provided between corresponding sides which need to be connected by heat insulation. Notches are arranged on the upper parts of the heat insulation slots. Hard heat insulation resins are filled with the heat insulation slots to form heat insulation bridges. Splice bars are arranged in the notches of the heat insulation slots and the inner sides at the bottom of the heat insulation slots. The distances of the splice bars at the bottom of the heat insulation slots are the same as the widths of the notches. The surfaces in the cavities of the heat insulation slots are rough surfaces, and the surfaces can be designed into the shapes of ripple or saw tooth, etc. A metal cut is provided between two splice bars at the bottom of the heat insulation slots. The utility model can provide the high-strength energy-saving thermal-insulation metal section bar which not only has the advantages of simple structure, higher production efficiency and rate of finished products, but also can guarantee energy conservation and heat insulation, has low heat insulation sectional area and high structural strength, and is practical for the doors and windows of the construction.
Description
[technical field] the utility model relates to a kind of strength energy-saving heat insulating metal section bar, belongs to Door for building window material technical field.
In [background technology] prior art, between the inside and outside shape of door and window, reach heat insulation mutually, following dual mode is generally arranged:, transplant a cutting with plastics and 2 to insert in some way and be pressed into therebetween (as shown in Figure 1) one, at shape 1 thermal insulation bridge cut-off place.This heat insulation mode and since plastics transplant a cutting 2 section bar be discrete, be hollow again, its sealing performance is bad, anti-steam weak effect; And only depend on plastics to transplant a cutting and connect two kinds of shapes, its comprehensive strength is low, and there is obvious defects in this structure.Two,,, inside and outside shape 1 is fused (as shown in Figure 2) with polyurethane structural foam or microporous polyurethane foam 3 at two kinds of shapes, 1 thermal insulation bridge cut-off place.This kind structure reduces the heat-insulation chamber structural strength owing to use foaming or microcellular foam material greatly, for guaranteeing bonding strength, can only adopt the deficiency that remedies intensity to increase the heat-insulation chamber volume; Be filled with heat-insulation chamber with polyurethane structural foam or microporous polyurethane foam, exist production efficiency low, easily produce bubble and waste product occurs, yield rate is hanged down problem.
In sum, existing Thermal insulation door and window shape, exist respectively heat insulation, sealing is bad, comprehensive strength is low or the heat-insulation chamber volume big, production efficiency and the low shortcoming of yield rate, is difficult to satisfied both energy-saving heat-insulatings, has the demand of the constructional materials of high structural strength again.
[summary of the invention] is for overcoming the deficiency of prior art, the purpose of the present utility model is to provide a kind of simple in structure, production efficiency and yield rate higher, and can either guarantee energy-saving heat-insulating, have the strength energy-saving heat insulating metal section bar of less heat insulation basal area and high structural strength again, to satisfy the needs of building doors and windows engineering.
Above-mentioned purpose of the present utility model realizes by following technological means:
A kind of strength energy-saving heat insulating metal section bar, comprise shape, it is characterized in that said shape is provided with heat dam between the position, opposite flank of the heat insulation connection of its needs, heat dam top has notch, is filled with the hard heat-insulating resin in the heat dam and forms heat insulation bridge.The notch of above-mentioned heat dam and bottom inside face thereof are provided with dowel; The dowel spacing of heat dam bottom is identical with width of rebate.At the heat dam cavity inner surface is rough surface, and this surface can be designed to shapes such as corrugated or zigzag.Be provided with the metal otch between bottom two dowels of above-mentioned heat dam, this otch forms after excising the heat dam bottom metal with cutting tool.
Strength energy-saving heat insulating metal section bar of the present utility model, its heat dam top has the notch of certain width, that filling is not foamed to be convenient to, high performance hard heat-insulating resin material; Its heat dam cavity inner surface is a rough surface, can adopt coarse forms such as corrugated or serration type, and it both can increase the inner surface of heat dam, can strengthen the bond strength between insulation resin and shape again.The width of heat dam and the degree of depth keep certain ratio, and its ratio size is taken at the structural strength that needs between heat insulation shape and decides with being connected the size of side relatively.For guaranteeing to connect effect of heat insulation between the shape, should excise the heat dam bottom metal, only connect the both sides shape with insulation resin charges in the heat dam, promptly form heat insulation bridge behind the excision bottom land metal.For increasing shape and insulation resin charges bonding strength, the notch and the bottom that are preferably in heat dam vertically are provided with two dowels that are parallel to each other along shape, and the distance between two dowels is identical with width of rebate.
Strength energy-saving heat insulating metal section bar provided by the utility model, its positive technique effect is: the position, opposite flank between the shape of the heat insulation connection of needs, be provided with heat dam, filling is hard heat-insulating resin that do not foam, high performance in the groove, therefore it can not sealing performance to occur bad, the defective of waterproof, gas weak effect, and have good dottle pin performance and higher bending resistance, horizontal tension and the vertically anti-performance of cutting; Do not foam, high performance hard heat-insulating resin simultaneously, filling need not foamed in heat dam, enhances productivity, and can not produce bubble and waste product occurs, the yield rate height.High performance insulation resin intensity height under the less situation of heat dam cavity volume, still can be held high structural strength for this reason.For construction project provides a kind of simple in structure, production efficiency and yield rate higher, and can guarantee energy-saving heat-insulating, again have low heat insulation area and high structural strength, can be for practical energy-saving heat-insulating high duty metal section bar.
