Abstract

The utility model belongs to an improved plastic steel window sectional material for buildings, which is provided with two subsidiary cavities which are symmetrically arranged a main cavity; the side of the main cavity is provided with two bosses for supporting glass to form two points of supporting. The improved plastic steel window sectional material can be made into T-shaped, L-shaped, and Z-shaped three shapes and can be used for making single-frame double-layer glass plastic steel windows (or doors). The utility model is particularly suitable for industrial and domestic building windows or doors in cold areas and has the advantages of energy saving, heat preservation, sealing property, corrosion resistance, low temperature resistance, cold brittleness, etc.

Description

Plastic-steel window section bar

The utility model belongs to the improvement design of building plastic-steel window profile.

The plastic-steel window is promptly made by the PVC material and is added " " shaped steel muscle in section bar, the primary cavity and gain the name.It has bright in luster, good looking appearance, long service life, be convenient to suitability for industrialized production, save advantage such as timber and used widely.But understand present user according to the designer and be ready that the 58 serial section bars that adopt have following shortcoming: referring to Fig. 1, known technology plastic-steel window section bar shown in Figure 2, existing section bar is mainly constructed and is comprised a primary cavity (1) and a paratype chamber (2), and when big face (3) when using outwardly, if outdoor-30 ℃, indoor 20 ℃ of north of china in winter, the temperature difference reaches 50 ℃, and section bar central authorities have only a primary cavity (1) and a paratype chamber (2), and cold and hot air can form certain convection current, and heat insulation effect is not good; Because the unreasonable existing section bar low-temperature impact-resistant performance of structure is bad, especially big of section bar (3) is measured according to 58 simple beam impact strengths in " GB8814-88 ", and is damaged higher, is difficult for being up to state standards; The primary cavity of prior art medium section (1) side only has a boss (4) that is used for supporting glass, because a boss forms single point supporting, behind the dress double-layer glass, glass is very easily damaged because of discontinuity; Limit by structure, the section bar shown in Fig. 1, Fig. 2 can only be made external-open plastic-steel window, can not in open.

The utility model purpose is: for overcoming above-mentioned defective, on existing section bar basis, improve design, a kind of novel plastic-steel window section bar is provided, to improve the section bar heat insulating ability, improve low-temperature resistant and shock resistant intensity, meet the need of market, a kind of plastic-steel window profile that can be applicable to northern China particularly is provided.

The technical scheme that adopts that achieves the above object is: this plastic-steel window section bar, have primary cavity (1) structure, and it is characterized in that this section bar has two paratype chambeies (2) and is symmetrical in primary cavity (1) setting.Side, section bar dominant shape chamber has two boss with supporting glass and forms 2 supportings.

By the plastic-steel window section bar that technique scheme is made, because of increasing a paratype chamber by big of section bar, three chambeies stop cross-ventilation successively when indoor/outdoor temperature-difference is very big, thereby have improved heat insulation effect; Set up a paratype chamber and also improved the low temperature impact strength of section bar, measured if press the GB8814-88 GB, qualification rate improves greatly so that can reach nearly 100% qualification rate; Because of this section bar primary cavity side has two boss structures that are used for supporting glass, the change single point supporting is 2 supportings, makes the glass more reasonable stress even; The sash of making of this section bar can external-open, again can in open, can satisfy the needs of different user; More reasonable because of the section material section structure, finished product window global stiffness has improved.

Fig. 1 is the 58T shape steel sash section material section organigram of known technology.

Fig. 2 is the 58L shape steel sash section material section organigram of known technology.

Fig. 3 is this plastic-steel window T-shape section bar (I) cross-section structure schematic diagram.

Fig. 4 is the left view of Fig. 3.

Fig. 5 is this plastic-steel window " L " type section bar (II) cross-section structure schematic diagram.

Fig. 6 is this plastic-steel window " Z " type section bar (III) cross-section structure schematic diagram.

Fig. 7 is for making plastic-steel window user mode assembling schematic diagram with this section bar.

Fig. 8 is for making open form user mode assembling schematic diagram in the plastic-steel window with this section bar.

Fig. 9 is for making plastic-steel open form user mode assembling outside window schematic diagram with this section bar.

The embodiment that provides below in conjunction with accompanying drawing further describes.Referring to Fig. 3, Fig. 5, the unitary construction of T-shape section bar (I) and " L " type section bar (II) and institute separately construct similar to Fig. 1, Fig. 2 section material section of the known technology used, difference is: the one, for heat-insulating property and the intensity that increases section bar, locating to have set up a paratype chamber (2) near section bar big (3), that is this section bar have two paratype chambeies (2) and are symmetrical in primary cavity (1) setting; The 2nd, it is two boss (5) as a boss (4) that supports that primary cavity in the known technology (1) side is used to install glass instead, promptly becomes a bit to support to change 2 supportings into, thereby has improved the stressing conditions of window glass.

Z type section material section shown in Figure 6 and Fig. 3, Fig. 5 are similar, also have two paratypes (2) and are symmetrical in that primary cavity (1) is provided with and have two boss (5) in each side of primary cavity (1) forms 2 supportings.

Make plastic-steel window user mode assembling schematic diagram referring to section bar of the present utility model shown in Figure 7.It is to make window frame by " L " type section bar (II), makes the sash fit applications by T-shape section bar (I).6 is that body of wall, 7 is that plastics expand tube, 8 is that screw, 9 is that fixture, 10 is that heat insulating material, 11 is that " " type reinforcement channel-section steel, 12 is that weather strip, 13 is that press strip, 14 is that spacer bar, 15 is a window glass among the figure.

Referring to Fig. 8, it is to make window frame by L type section bar (II), makes sash by " Z " type section bar (III), is mounted to the plastic-steel window of inside open form.

Referring to Fig. 9, it is to make window frame by " L " type section bar (II), makes sash by " Z " type section bar (III), is mounted to the plastic-steel window of outside open form.

As seen from the above-described embodiment, can be made into T-shape, " L " type, two kinds of section bars of " Z " type with this section bar.Can be made into the plastic-steel window of single frame double-layer glass with these three kinds of section bars, and can select the inside and outside multi-form mounting means of opening, be specially adapted to cold district worker, people's building window or door.That this door and window has is energy-conservation, insulation, sound insulaton, ageing-resistant, corrosion-resistant, shock-resistant, intensity is high, low temperature resistant, anti-cold short, dustproof, airtight, advantage such as watertightness is good, easy to assembly, need not keep in repair.
