Abstract

The invention discloses a mullion which comprises a strip wooden core, an outer lateral sheath and an inner lateral sheath. The inner lateral part of the strip wooden core is coated by the inner lateral sheath. The outer lateral part of the strip wooden core is coated by the outer lateral sheath. The relative positioning of the outer lateral sheath and the inner lateral sheath in the cross section of the mullion is realized through a buckling structure, wherein both the outer lateral sheath and the inner lateral sheath are of a double-layer composite co-extrusion structure and are respectively provided with wood plastic layers serving as the outer layers and hard PVC (polyvinyl chloride) layers serving as the inner layers. The technical scheme has the advantages of reasonable structure, good surface decoration effect, high structure strength and the like.

Description

A kind of window mullion

Technical field

The present invention relates to door window section material technical field, relate in particular to a kind of window mullion.

Background technology

In the prior art; General full wood, aluminium alloys or the plastic material of adopting of door window mullion; That the door window mullion of full timber matter exists is perishable, be prone to damage by worms, shortcomings such as difficulty of processing is big, cost height; There are shortcomings such as surface decoration effect is single, effect of heat insulation difference in the door window mullion of aluminum alloy material, and the door window mullion of plastic material adopts plastic extruding forming, receives the moulding process restriction to have shortcomings such as structural strength is low, surface decoration effect is single.

Summary of the invention

In order to solve above-mentioned technical problem, the purpose of this invention is to provide a kind of window mullion, have rational in infrastructure, surface decoration effect good, the structural strength advantages of higher.

In order to reach above-mentioned purpose, the technical scheme below the present invention has adopted:

A kind of window mullion; Comprise the reel, outside jacket and the inboard jacket that are strip, the inside portion of inboard jacket parcel strip reel, the outside portion of outside jacket parcel strip reel; Outside jacket and inboard jacket are implemented in the relative positioning in stile's cross section in this through fastening structure; Wherein, said outside jacket and inboard jacket all adopt the two-layer compound coextruded structure, and be outer for wood is moulded layer, internal layer is the hard PVC layer.

As preferably; Said outside jacket has the groove that holds strip reel outside portion; Said fastening structure is meant: the said outside is wrapped on the two side of its groove and is formed with catching groove, and said inboard jacket is local to be got in the groove of said outside jacket and at inboard jacket skin and be formed with the profile that is interlocked with said catching groove.The fastening structure advantages of simple is reliable like this.

As preferably, be formed with the seal groove that holds weather strip on the two side of the groove of said outside jacket.So not only can be used for fixing door and window sealing strip, thus and can be with reel and the extraneous application life that seals stile in the raising.

As preferably, said inboard jacket has the groove that holds strip reel inside portion, and the groove inwall of said outside jacket and inboard jacket is the hard PVC layer.Can further guarantee the intensity and the application life of a window mullion like this.

As preferably, the cross section of said strip reel is T-shaped, and the stub end of T shape is the outside portion, and the little head end of T shape is the inside portion.This spline structure is more rationally reliable.

The present invention is owing to adopted above technical scheme; Outside jacket and inboard jacket adopt the double-layer coextrusion moulding; Wood is moulded skin and is had the good surface appearance decorative effect; Hard PVC has good structural strength, be provided with reel can further guarantee in stile's support strength, thereby have rational in infrastructure, cost is low, surface decoration effect good, the structural strength advantages of higher.

The specific embodiment

Do a detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention.

Embodiment 1:

A kind of window mullion as shown in Figure 1; Comprise the reel 2, outside jacket 1 and the inboard jacket 3 that are strip, the inside portion of inboard jacket 3 parcel strip reels 2, the outside portion of outside jacket 1 parcel strip reel 2; Outside jacket 1 is implemented in the relative positioning in stile's cross section in this with inboard jacket 3 through fastening structure; Wherein, said outside jacket 1 all adopts the two-layer compound coextruded structure with inboard jacket 3, and is outer for wood is moulded

layer

12,32, internal layer is a

hard PVC layer

11,31.

In the present embodiment; Said outside jacket 1 has the groove 13 that holds strip reel 2 outside portions; Said fastening structure is meant: said outside jacket 1 is formed with catching groove 14 on the two side of its groove 13, is formed with the profile 34 that is interlocked with said catching groove 14 in the groove 13 of the said outside of said inboard jacket 3 local entering jacket 1 and at inboard jacket 3 skins.Be formed with the seal groove 15 that holds weather strip 4 on the two side of the groove 13 of said outside jacket 1.Said inboard jacket 3 has the groove 33 that holds strip reel 2 inside portions, and

groove

13,33 inwalls of said outside jacket 1 and inboard jacket 3 are hard PVC layer 11,31.The cross section of said strip reel 2 is T-shaped, and the stub end 21 of T shape is the outside portion, and the microcephaly of T shape holds 22 to be the inside portion.

As shown in Figure 2, during installation, according to inboard jacket 3, reel 2 and the outside jacket 1 of size needs intercepting certain-length; T shape microcephaly with reel holds 22 to embed in the groove 33 of inboard jacket 3 earlier; Again from an end of inboard jacket 3 along catching groove 14 with profile 34 buckling sleeves on outside jacket 1, and it is concordant to both to promote outside jacket 1, so far be assembled into complete in stile; Embed fixing seal bar 4 at seal groove 15 then; And with weather strip 4 expose side bonds in inboard jacket 3 outsides, at last with the door window mullion be installed on the doorframe, two door leafs 5, between 6, the side that exposes of weather strip 4 is used for filling the space between two

door leafs

5,6 and the stile.
