Abstract

The utility model provides a curtain wall section, which is used for decoration for outer walls. An original integration structure is changed into a composite structure whose front and back parts are fastened, the fastening positions of the front and the back parts all adopt a round structure. So the strength and the rigidity of a mullion are basically not reduced, the utilization rate of materials is enhanced, and the cost is reduced about 15 percent to 20 percent.

Description

A kind of novel curtain wall section bar

The utility model relates to a kind of decoration of exterior wall novel curtain wall section bar.

Along with the development of decorative craft, the exterior wall finishing class improves constantly, and aluminum alloy glass curtain wall is widely used.No matter be bright frame or half latent, fully implicit solution glass, all need the aluminium alloys munnion.Though because high different of building type style, moulding difference and interlayer, thickness of aluminium alloys munnion (L size among the figure) and basal area size are also answered different.But because the specification of aluminum current section bar is limited, for satisfying this demand, each manufacturer produces curtain wall profiles group product and differs, from 120 to 210 series have been developed at present, only depending on above-mentioned series to be as the criterion feeds intake, so just caused the part waste of aluminium extruded sections, giving again to make with Installation unit has increased the money of getting the raw materials ready.Owing to the high restriction of floor interlayer, the stub bar that cuts down all can not use, and is again a kind of waste simultaneously, causes the engineering cost of aluminum alloy glass curtain wall high.

The purpose of this utility model provides a kind of novel curtain wall section bar.

It is that the structure of traditional aluminium extruded sections munnion is improved, and former integrative-structure is become the combining structure of forward and backward two parts snapping, and adopts ＂ S ＂ shape to fasten interface.

The advantage of this structure is:

1, front and rear as requested size process respectively, it is anterior as long as outward appearance kind (bright frame, half implied or are latent entirely) is the same, can be made into general part; Different size can be made according to the high requirement of strength of interlayer in the rear portion.When mounted, anterior section bar is determined by the outward appearance kind; The rear portion section bar can adopt different specifications according to the blast strength factor difference of floor height, has solved originally from bottom to the constant wasting phenomenon of high-rise section material section.

When 2, installing, section bar is not subjected to the restriction of interlamellar spacing, the stub bar that cuts down use capable of being combined, and simultaneously, maintaining one at the front and rear of section bar is that another is sliceable under the situation of one, intensity is unaffected like this, has improved the utilization rate of material greatly.

3, versatility is good, and former fabrication and installation producer need be equipped with multiple serial curtain wall material, increases the stock-sales ratio of producer.Now only need be equipped with anterior section bar material, can be common to high, medium and low shelves curtain wall, rear portion section bar material can get final product according to the floor demand is supporting.

Because above-mentioned some superiority makes it engineering cost and reduces by a relatively large margin.

Theoretically with Practical Design in, to the check of the strength and stiffness of aluminium alloys munnion, all relevant with its moment of inertia, make into after this new structure section bar, its moment of inertia evaluation does not change, so the strength and stiffness of munnion do not reduce basically, meets engine request fully.And, use above-mentioned novel aluminum alloy munnion can reduce the about 15-20% of engineering cost by Practical Calculation.

Describe its technical solution in detail below in conjunction with the embodiment accompanying drawing:

Fig. 1 is the cross sectional representation of novel curtain wall section bar munnion

Fig. 2 is the partial enlarged drawing at novel curtain wall section bar munnion front and rear portions snapping place

Referring to Fig. 1 and 2, forwardly 1 and the snapping place at rear portion 2, adopt fillet 3 and the 4 ＂ S ＂ shapes that constitute to fasten interface.This structure can be common to high, medium and low shelves finishing, no matter and be the curtain wall of the sort of outward appearance kind (entirely bright frame, half implied or latent).L represents the thickness of munnion among the figure.

Claims

A kind of decoration of exterior wall section bar---the novel curtain wall section bar is characterized in that: the snapping place of section bar (1) and rear portion section bar (2) forwardly, adopt fillet (3) and (4) to constitute ＂ S ＂ shape fastening interface.
