Description

空心实心交织式铝格网构造
本实用新型涉及一种铝格网构造,乃指一种一体成型之铝格网体且为空心网格与实心网格呈交织状结构之新型铝格网。
市面上铝格网之使用极为广泛,而此种铝格网之制造技术乃系一澳大利亚厂商所发明,并已在英国及日本申请并获准专利,其相关之专利引证资料如下:英国发明专利第1601051号、1600947号及1588197号,日本地区则为特许22462号、7264号、36108号、24021号及13186号,上述专利权都是有关制造铝格网之机械设备及方法,主要包括铝挤压型板上之凿孔机械及将已凿孔之铝挤压型板拉伸成铝格网之拉网机械,由于此等方式所作出之铝格网,极易大量制造且网格方式可作各样变化设计,故推行后在市场上极受欢迎,也使用了相当长之时间,但使用之初期,此等铝格网产品之肋条皆为实心之细杆体或片状体,成型后之铝格网上无法完全取代不锈钢或其他金属管材所制作之格网产品,如门、窗防盗网或阳台栏杆及座椅承靠面等,其原因乃是相同量之铝合金所成型之实心肋条铝格网,肋条表面积不够大,造成承受压力之面积有限,其外观感觉亦不如其他金属材管料美观,若使用于如住宅别墅等阳台栏杆或护栏等,因效果不佳而不被采用,而且实心杆状体,其各肋条或所构成之整体网状面,在抗剪力与抗弯力方面不如作成空心管状体,这是简单的力学原理,此即铝格网专利产品行销于市多年仍未取代金属管网消费市场之原因。实心肋条之铝格网由于抗剪力及抗弯力均差,也影响了其更进一步之发展,本发明人曾首创出一种多功能多变化之空心肋条铝格网体构造,使所成型之铝格网成为空心肋条之结构,使在相同铝合金材料下,所成型之空心铝格网具有较宽广之表面积及较强之抗剪、抗弯强度,从而使其更适合使用于门、窗阳台护栏或椅子坐面等,而且可以发挥空心设计之优点,如于空心内部之空间加设补强肋条,或于该内部空间直接成型出组装用之螺孔槽等等,但是盗者往往工具齐备,若铝格网只要破坏几个小地方即可被掀成一开口而侵入,则此种铝格网之防盗功能即成问题了,又网格孔隙若太大易被手或器具探入,因此一种良好之铝格网结构本身应具备大小适当之网格密度且抗破坏性强,目前之实心肋条或空心肋条之铝格网,则各有优劣未能得兼,网格较大成为空心铝格网美中不足之处,而且再就外观需求而言空心网格之结构强度也使其成型之网格花样受限制,而无法作较多变化,也间接影响消费者之喜爱程度了。
本实用新型的目的在于提供一种兼具实心肋条的网眼密及空心肋条的强度高的优点,且格网图案美观富于变化的铝格网,即空心与实心交织的铝格网构造。
本实用新型的技术方案是:于铝挤压板上设有数个空心肋条及数个实心肋条,各肋条间有适当宽度之副肋作为连接片,并在副肋上开设适当之槽孔,使拉伸成型后之铝格网体中,能以空心肋条构成整体铝格网之较大网格部分,同时于该较大网格之内部又可成型有由实心肋条所构成之较小网格形成空心及实心交织式结构。其空心肋条及实心肋条于结构断面上可呈多种交叉变化之直线排列方式,或者空心肋条及实心肋条之截面形状设计成多种变化,均可使拉伸成型之铝格网成多种变化之格网整体花样或格网肋条之不同截面形状。

由图1、2所示,可知现有空心网格体(1)包括有全为空心之肋条(11)及作为连接片之副肋(12),由铝挤型机将铝锭先挤出铝挤型板,再由各副肋(12)处经设计而开设出槽孔,再利用拉网机拉伸成型得一整体之空心铝格网,图中之各网格(13)即系由位于副肋(12)上之槽孔被拉伸而成,而该网格(13)之大小与槽孔之长度及肋条(11)之强度有关,即图中所示网格(13)之横向宽度(14)及张角(15)皆受肋条(11)之强度影响,而空心肋条(11)之断面形状具有较大抗弯力,故在尽量维持肋条(11)断面形状不变形之条件下,使拉伸之张角(15)及宽度(14)受到限制,如以图1之肋条断面形状而言,经实物作拉伸试验,张角(15)只能拉伸至36度左右,故欲有适当宽度(14)之网格(13)时,势必将槽孔之长度增长才可,如此也使网格(13)相对增大,而以此类铝格网之构造而言,未拉伸前之挤型板一般皆因挤型机之性能参数而有一定宽度之限制,而将该挤型板拉伸成网状体即应拉伸至最大宽度为最佳,即构成一单件铝格网之宽度,但限于空心肋条(11)之结构,使单件空心铝格网之宽度皆远大于一般实心铝格网体,而网格却相对较大,而且成型之网格花样亦远比实心铝格网单调,无法作较富复杂之多样变化;而若欲将空心肋条拉伸至超越其限制条件,则由于抗弯力及转角处之角位差关系(即空心肋条两侧边在转角处形成位差),势必造成挤料而产生变形或断裂,至于第三图中之空心肋条(11)内,可另加设补强肋作为空心肋条之加强,此则可随模具之设计及实际需要而作变更,并不限制在每一空心肋条内皆作如此之设计。
本新型即针对上述空心铝格网之缺憾加以改良,利用实心铝格网之易拉伸、网格密及花样较富变化之优点,将之融合入空心网格内,使成型之铝格网内,具有由空心肋条构成之较大网格部分,而于各空心肋条之各网格内部又成型有实心肋条所构成之辅助性的较小网格,如图4、图5、图8、图9、图11、图13、图15、图17、图19、图21、图23、图25、图27所示之铝格网所示,图中,空心肋条(21)、(31)、(41)、(51)、(61)、(71)、(81)、(91)、(101)、(111)及(121)等均构成空心铝格网之较大网格部分,而比较大网格之花样较无变化,而再籍实心肋条(22)、(32)、(42)、(52)、(62)、(72)、(82)、(92)、(102)、(112)及(122)在空心肋条大网格内又构成一较小网格,而由于实心肋条较易拉伸,故花样可较富变化,只要将副肋上所开设之槽孔位置及长短加以设计,即可拉伸出不同花样之网格来,整体即形成空心实心交织式之铝格网体。
又由图3至图27所示各式空心实心交织式铝格网构造中,其不同处包括:
(A)空心或实心肋条所形成网格花样不同;
(B)各空心网格内可设有实心网格,或间序排列设置(即可左右空置一网格不设内实心网格);
(C)各空心肋条及实心肋条之断面形状亦可经适当设计,可产生各种造型之断面形状,如附加遮阳片等;
(D)空心肋条及实心肋条之纵向长度可较不受限制,且实心肋条可设置于副肋(连接片23)之单边或双边;
(E)空心肋条及实心肋条之数目不拘,其在断面上直线状之排列亦可设计成各种不同之交叉方式,而相同断面之空心、实心肋条排列方式亦可拉伸成不同之网格花样;
在拉伸成铝格网之制程中,各实心肋条对称而平均地对空心肋条产生拉伸力之平衡作用,故铝格网之成型花样更形完整而美观。
图25及图27中所示之空心肋条(111)及(121)形成之网格张角较大,接近于最佳之90度角,但此非表示空心肋条可随心所欲拉伸,只是表示本创作之交织式铝格网构造于花样上可作各式变化,包括90度张角,但此大张角之空心肋条势必造成其他部位之变形,简言之,若欲达大张角之空心肋条,则可能须容许空心肋条本身之变形,如空心肋条在张角处(即连接之副肋处),以断面视之,可能产生两边挤料及中央凹陷或挡卡位等现象。
本实用新具有空心格网之高强度,又有实心格网之高密度,在使用上更加适应多种需要,且可变换图案,外形美观,生产工艺简便是有广泛前景的新结构。
