Abstract

The utility model discloses a thermal bridge steel section material for doors and windows, which mainly solves following problems of other section materials of the same type. Due to high elasticity modulus of steel, such section materials can not closely attach to the plastic plate, and aluminum plate between plastic connection plates still conducts heat through radiation, thus heat insulation effect is poor. The technical scheme to solve the problem is that two semi-circle grooves are available at inner side of steel section material at the joint of the steel section material and the plastic piece, and the folding end of the steel section material semi-encloses a semi-circle groove; irregularly positioned cone indentation is made on interface of the steel section material and the plastic piece; the plastic piece takes up all the space between inside of the two bars of steel section materials, and the semi-enclosed semi-circle groove is filled with plastics to form two plastic barbs which firmly combine the steel section materials at two sides. The utility model is used for making mullions, leaf materials and central reinforcing materials of doors and windows of various types.

Description

A kind of insulated bridge steel window and door sectional material

Technical field:

The utility model relates to steel window and door sectional material, the particularly steel window and door sectional material of thermal insulation, this section bar be used for making all kinds of glass door and windows frame material, fan material, in material very.

Background technology:

At Chinese notice of authorization CN2546595Y, the utility model name is called and discloses the disconnected heat bridge structure of a kind of steel window and door sectional material in " steel window and door sectional material break heat bridge ", its purpose is the conduction of heat of blocking-up steel, improve the heat-insulating property of steel casement door window, formation is that steel profile is shaped on notch, notch edges is shaped on the taper platform that is evenly distributed, vertically separate with aluminium sheet between two plastics junction plates, its two ends are shaped on groove and the identical groove of taper platform that slows down resilience, during composite molding, the steel profile notch is inserted at plastics junction plate two ends respectively, again through the compounding machine barrel roll, the edger roll effect is with steel profile and firm being interlocked of plastics junction plate, weak point is because steel profile modulus of elasticity height, easily produce resilience and can not with the tight interlock of plastics junction plate, secondly, aluminium sheet between two plastics junction plates still can be with thermal-radiating mode transferring heat energy, so the thermal resistance poor effect.

Summary of the invention:

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and provides a kind of good heat-insulation effect, well-set insulated bridge steel window and door sectional material.

The purpose of this utility model can reach by following scheme:

A kind of insulated bridge steel window and door sectional material, comprise two steel profile and a working of plastics therebetween, in steel profile and working of plastics junction, two semi-circular groove are arranged in the inboard of steel profile, semi-circular groove that steel profile folded end therebetween is semiclosed is shaped on the taper impression of irregular alignment on the contact surface of this steel profile and working of plastics; The institute that this working of plastics has occupied between two steel profile inboards has living space, and plastics have been full of semi-enclosed semi-circular groove, form two plastics barbs, and the steel profile of both sides is combined into one securely.

The utility model has following advantage compared to existing technology:

1, good heat-insulation effect, it has not only cut off the conduction of heat of steel profile, has also cut off the heat radiation between two steel profile.

2, profile structure is simple, firm.
