Description
技术领域
本发明涉及一种钢芯撑,其包括从腹板侧正交延伸的平行凸缘,尤其涉及一种芯撑,其在腹板内配有至少一个沟槽,并包括从腹板的沟槽侧延伸的辅助凸缘。
背景技术
采用水平槽梁来作为顶部及底部并采用槽梁内的纵芯撑的墙内结构已广为人知。一般而言。芯撑也采用槽梁形状,二者均采用冷成形金属,一般为钢。同样,金属建筑物采用围梁(侧圈梁)及顶梁(顶圈梁)。顶椽、顶梁、底梁及接头还可采用槽形构件。(以下的“芯撑”、“金属芯撑”、“钢芯撑”及“建筑芯撑”不构成限定,而只是一种同义词,而且包括该芯撑可采的所有材料)。
各种缺陷及翘曲(欧拉型或局部型)均可能是灾难性的。也就是说,如果构件产生压缩翘曲,即侧向移动并缩短长度,则建筑结构便可能难以承受负荷。钢质芯撑可用作细长的支撑柱,它的长度大大长于它的截面积。欧拉公式表明,细长支撑柱具有它的临界翘曲负荷。如果负荷超过临界负荷,则微小的一点影响便会造成支撑柱产生侧弯,如附图所示,它将增大其弯矩。由于弯矩随着相对纵向轴线的距离而增大,因而轻微的弯曲也会迅速在支撑柱内产生无限大的横向位移;即产生翘曲。这意味着,任何翘曲都会进一步加大翘曲量,因而这种缺陷是灾难性的。
传统的钢芯撑结构包括从腹板来正交延伸的一对并行凸缘。凸缘的远端一般向内稍微弯曲,从而增大压缩稳定性,进而使双维平凸缘形成三维结构。为此目的,“压缩稳定性,强度或应力”意味着结构在翘曲或变形从而失去支撑力之前可承受的负荷的测量基准值。
这种芯撑的节能效果不好。比如,对内壁而言,金属芯撑起着热传导的作用,从而与木材及其它材料相比,可增大整个壁面的热传导性。在金属建筑物中,芯撑(围梁及顶梁)相对外部材料层为直接金属接触,从而成为外层至内层的热导体。热量穿过腹板,如果要大大降低热传导性,则需要取下腹板上的材料,从而在腹板内开槽。对该沟槽而言,需要除去金属,从而减小热通路,因而芯撑将降低传热性。此外,该沟槽可容纳隔热材料,从而进一步妨碍传导性。
同样,钢质芯撑是良好的声音传导体,适于各种用途。长期以来用于降低声音通过金属壁芯撑来传导。对传热性而言,腹板或凸缘的主要部分的重新成形将降低芯撑及壁面的声音传导性。
发明内容
本发明的主要目的在于,提高传统的钢质芯撑的压缩稳定性、强度及抗弯性。另一目的在于,降低芯撑的热传导性及声音传导性,同时提高抗弯性和压缩稳定性及强度。为此,另一目的在于,在芯撑腹板内设置一个或多个沟槽,从而断开腹板的传导性,从沟槽内的腹板外伸,此外还设置第一凸缘,从而增大芯撑在弯曲及压缩下可承受的负荷。
在第一种实施方式中,建筑芯撑具有至少一个辅助凸缘,其从腹板的对应沟槽一侧来延伸。在第二实施方式中,建筑芯撑具有多个小孔,其在芯撑内穿插,使腹板或凸缘形成孔洞状,并从孔洞处外伸。
在形成这些辅助凸缘时,在腹板上冲压出凸缘的三个侧边,然而使辅助凸缘从腹板向第四个未切割边弯曲,从而在腹板上形成孔洞。其结果是,辅助凸缘从腹板的槽边外伸。辅助凸缘通常与腹板正交,并与从腹板边外伸的第一凸缘平行,当然也可以相对腹板成一个角度,而不是正交。芯撑腹板内的沟槽形成一个缩小的腹板区,热量或声音可由此而传导。
切割腹板形成沟槽,同时形成凸缘,从而在中部及顶部将腹板的沟槽区分成二个等边,然后将面板从腹板平面向外折叠,同时形成沟槽及连续的辅助凸缘。
也可以在沟顶将沟槽区切割(或冲压)成U形,并在沟底切割成倒置的U形,然后通过它们之间的中心切槽来连接。将顶部及底部U形板向外折叠,从而在顶部及底部形成水平的辅助凸缘,然后向外折叠侧面板,从而形成纵向辅助凸缘。
芯撑不会因沟槽而降低强度,相反,芯撑事实上可通过几个机构来加强强度。首先,传统芯撑的腹板的纵向长度具有较大的纵向平面,它在负荷下易于产生局部剪切翘曲,从而导致欧拉翘曲。如果沟槽具有辅助凸缘,则会降低其程度。即,与标准的钢质芯撑相比,辅助凸缘金属芯撑(″SFMS″)实际上可通过在腹板上产生较小的平面来使腹板平面增大刚度,从而可增大局部剪切翘曲阻力。
计算表明,如果对SFMS施加纵向负荷,则可产生更好的翘曲稳定性,因为重心从腹板平面向外移动,从而开启沟槽部。这样,纵向负荷可在整个SFMS截面上更均匀地分布;这与标准的钢质芯撑不同;这样,局部翘曲效果将需要大于标准钢质芯撑所能接受的纵向负荷。SFMS还可利用辅助凸缘所提供的新性能来增大抗欧拉翘曲性(长轴侧向变形)。简言之,对在沟槽内弯曲的芯撑而言,与腹板正交的辅助凸缘及主凸缘必须也弯曲,但对辅助凸缘而言,可增大抗弯力。
辅助凸缘可以是连续的(完全穿过沟槽),也可以是断续的(不完全穿过沟槽),当然前者比后者可提供更大的强度及结构稳定性。如果最终的SFMS产品均采用传统的金属芯撑的原材料,当辅助凸缘从沟槽侧的整个长度来延伸时,SFMS将超过传统芯撑的整个剖面区,这样,与传统芯撑相比,可支撑压缩负荷,并可产生附加刚性,从而改善芯撑的稳定性。下列X轴线及Y轴线弯曲计算可证明这一点。
计算表明,在沟槽侧及末端增设辅助凸缘,不仅可完全消除因沟槽而引起的任何压缩强度损失,而且还可在未设置沟槽或辅助凸缘的未改进芯撑上增大它。即,与未设置相比,芯撑可通过沟槽及辅助凸缘来承受更大的压力,或纵向负荷,或弯曲负荷。下列计算是典型计算:
下列计算假设采用16号“C”剖面槽钢,6”×21/2”(0.0598”壁厚)芯撑。
承重柱的强度可由围绕主轴线X-X的惯性矩来表示,在该位置上可首先发生翘曲。当力矩达到足够高的值时,即欧拉翘曲,柱梁将发生翘曲。该值与惯性矩成比例,因此,惯性矩越高,柱梁在翘曲前可承受的负荷便越大。
下列公式用于计算槽形剖面围绕轴线X-X的惯性矩(in4)。相应部分如图27所示。
式中,
h=0.0598英寸,是16号冷成形钢的厚度。
b=各剖面的宽度。对Ix-x而言,取决于二个宽度即2.50英寸及1.00英寸之间的中心轴线,且垂直于0.375英寸尺寸。对Iy-y而言,取决于与二个宽度即2.50英寸及1.00英寸垂直的轴线,且平行于0.375英寸尺寸。
d=相对面积″A″的矩心的中心轴线的距离(in)。
中心轴线处于芯撑重心CG的矩心处。利用下列公式来确定:
CGy-y i=yAi/At
式中,Ai表示组成全部剖面区At各区域的剖面面积。
部件 | A,面积(in2) | y(in) | yA(in3) |
A-1 | 0.0598)(2.5()2=0.2990 | 1.25 | 0.374 |
A-2 | (0.0598)(1)2=0.1196 | 0.5 | 0.0598 |
A-3 | (0.0598)(2)(2)=0.2392 | 0.0299 | 0.0072 |
A-4 | (0.0598)(0.375)2=0.0449 | 2.5 | 0.1123 |
合计 | At=0.7027 | yAi=0.5533 |
表1:
利用表1内的值来计算CG,
CGy-y=yA/A=(0.5533)/(0.7027)=0.7868英寸,距离腹板的内侧面。
通过该公式,可计算出辅助凸缘芯撑的Ix-x及Iy-y值。
为确定配有辅助凸缘的芯撑可承受的负荷增大比例,接下来计算标准钢芯撑的主轴线X-X的惯性矩(没有辅助凸缘的长处)。如上所述代入各值,
配有辅助凸缘的芯撑的比例改善量为[(4.15-3.23)/(4.15)](100),或者大于同一标准钢芯撑22.3%。
已确认,从腹板外伸且配有辅助凸缘的开槽芯撑的芯撑局部剪应力偏转的耐力也得到增大。即,与没有这些特性的金属芯撑相比,配有辅助凸缘的芯撑也可在配有辅助凸缘的开槽金属芯撑上,支撑较大的侧向负荷,或者非纵向芯撑的中间负荷。
尽管芯撑由辅助凸缘来加强,但辅助凸缘的最大长处在于,腹板可开槽,而不降低芯撑的结构整体性,事实上,可提供一种得到增强的结构。沟槽可通过穿过壁面的腹板来断开热流(以及声流)。在上述配有辅助凸缘的开槽芯撑之前,人们不愿意采用金属芯撑,因为隔热性不好;事实上,它们是良好的绝热性,但节能及降噪效果不佳。木材是良好的芯撑材料,因为它的传导度低。2”×6”芯撑木材的“R”系数(枞树、松树及云杉)是361K/W。[1W/mK=0.578BTU/Hr-ft-°F]。相同尺寸的开槽钢质芯撑的“R”系数为846K/W。木质芯撑的热损失率为0.055W,开槽钢芯撑为0.024KW,或者小于一半。钢质芯撑显然具有竞争力,甚至是优先选择的。此外,沟槽内没有进行热传导的空气,因而还具有隔热性。上述芯撑壁在芯撑之间配用绝热泡沫。泡沫被吹入壁内时为液状,可通过沟槽流入芯撑的若干个区域内。当泡沫干燥后,泡沫不仅可充满芯撑之间的区域,而且泡沫还可保留在芯撑槽内,从而防止空气流入,从而防止热传导及热对流。配有沟槽的芯撑由辅助凸缘而增强结构性,并由沟槽及绝热层而保持绝热,从而可成为一种具有吸引力的墙壁结构替代物。
显然,根据SFMS的需要,SFMS上辅助凸缘制造过程中所产生的沟槽可具有各种宽度及长度。其长度及宽度的改变可影响到各种几何性能。
在金属片上钻孔、剪切或冲压通常会产生毛边,从而从钻孔、剪切或冲压后的孔或侧边外伸。在这里忽略这种现象,不属于“凸缘”术语的使用范围。此处“凸缘”术语的使用意味着一种广义的金属片结构,一般为平板,其距离远大于毛边,其中凸缘所采用的材料远大于切割毛边,且用于结构目的,比如增大强度。如上所述,凸缘的另一结构目的在于,芯撑重心远离凸缘所外延的金属片(比如腹板),其没有毛边。如图所示,所谓凸缘一般包括至少一个形成有沟槽的主要部分。

具体实施方式
本发明的金属沟槽芯撑10用于传统的芯撑壁结构。在传统的墙壁及建筑物结构中,多个芯撑在水平地面梁与顶梁100之间垂直平行设置。槽芯撑102与顶梁100相接,向下开口,并容纳芯撑10的上端11。同样,沟芯撑底部104与地梁100相接,向上开口,并容纳下芯撑端13。由于小梁100用于侧面支撑,或者支撑横向负荷,因而大于并强于芯撑10,其用于支撑压缩负荷,或者纵向负荷。芯撑10的纵向负荷及其纵向力分布不同于小梁100,因而可适于纵向负荷,这种设计差异不适于侧面力分布式小梁。下列方式只适于纵向负荷芯撑。
芯撑10包括一个传统的C型槽钢12,其具有一对平行的主凸缘14,从腹板16正交延伸并被它分割。在优先实施方式中,在腹板16内设置至少一个沟槽18,最好设置多个,从而使至少一个最好是二个辅助凸缘20在沟槽18上从第一及第二沟槽侧22、23向外弯曲,从而围绕沟槽18并在主凸缘14之间向内延伸。这样,辅助凸缘14便包括一个主要部分,一般为腹板16的三分之一,从腹板弯曲,从而形成沟槽。沟槽18可排成一列或多列19。二列或多列19可并排配置于沟槽18上,并邻近沟槽列,如图27、28及33所示,或者配置于一列19’的沟槽18’上,从而在相邻列19”之间错开或重叠。
辅助凸缘20最好在腹板16上,从所述沟侧22、24向内对称延伸。这样,各辅助凸缘20便在腹板近端与远端之间延伸,其距离等于沟槽18的一半宽度(如果稍做变动,腹板16形成沟槽18,配有一个辅助凸缘20’,从沟槽侧22、24向内弯曲,在该场合下,辅助凸缘20’的长度成为沟槽18的宽度)。尽管辅助凸缘最好从腹板来正交延伸,但也可以以不同于对腹板垂直的任意角度从腹板来延伸,如图26所示。
联单辅助凸缘20包括一个主要部分,大多数的腹板16在主凸缘14之间向内弯曲,从而形成沟槽18,辅助凸缘20使芯撑剖面重心远离腹板16,从而将负荷支撑从腹板16转移至主凸缘14上。在该优先实施方式中,辅助凸缘20从多个沟槽18的各22、24来延伸,从而在腹板16内垂直排列,进而保持芯撑对称,从而在芯撑内形成均匀的负荷支撑。在另一实施方式中,第一辅助凸缘20’在腹板16上,从第一沟槽18a的第一沟槽侧22来延伸,第二辅助凸缘21’在腹板16上,从第二沟槽18b的第二沟槽侧24向内延伸,第二沟槽18b邻近所述第一沟槽18a,第三辅助凸缘20”在腹板上,从第三沟槽18c的第一沟槽侧22来延伸,第三沟槽18c邻近第二沟槽18b,第四辅助凸缘21”在腹板上,从邻近第三沟槽18c的第四沟槽18d的第二沟槽侧22向内延伸,第四沟槽18d邻近第三沟槽18c,从而使辅助凸缘20’、21’、20”、21”在第一及第二沟槽22、24之间连续邻近沟槽。另一种方式是连续通过腹板16,从而在各沟槽的第一及第二侧22、24上具有相同数量的辅助凸缘20、21。这样,辅助凸缘20处于主凸缘14之间,从腹板16来进一步延伸,从而使芯撑剖面重心进一步远离腹板16,从而可有效地从腹板16向主凸缘14传递负荷支撑。
在另一实施方式中,腹板16’用于形成所述的凸缘20,其从沟槽侧22、24来延伸,并形成凸缘20,该凸缘从沟槽顶部26及底部28来弯曲,从而形成四个辅助凸缘30,该凸缘从沟槽外周来弯曲,沟槽从腹板16向内或向外来延伸。
尽管优先实施方式中的辅助凸缘20向内延伸,从而使芯撑重心向内移动,从而远离腹板16,由此从腹板16向主凸缘14转移更多的芯撑支撑力,然而辅助凸缘20也可以向外弯曲,从而远离芯撑10。如上所述,向内移动重心的结构性长处在于:芯撑上的负荷可更好地分布到凸缘上,而不是主要集中在腹板上。同样,另一结构性长处在于:使辅助凸缘20腹板从向外移。如上所述,芯撑惯性矩的主要成份是1=bh3/12,其中,b表示芯撑基础(腹板尺寸方向),h表示高度(凸缘取向方向)。即使少量增大高度,也会大大增加芯撑强度。如果芯撑一开始具有2英寸凸缘,而且使辅助凸缘向外移动,从而增大2英寸,则芯撑强度便可增大43/23,即64/8=8。某些辅助凸缘也可以向内弯曲,而某些则可以向外弯曲。
在优先实施方式中,沟槽为矩形,辅助凸缘20从沟槽18来延伸,延伸方式为垂直延伸、与主凸缘平行延伸、水平延伸、与主凸缘14正交延伸。然而,本发明也包括其它的沟槽形状。比如,沟槽端(顶部及/或底部)可以为三角状,各有二个辅助凸缘,从三角腿来弯曲并延伸,如图20-22所示。同样,沟槽顶部及/或底部可以为曲面状,如图23-25所示,并配有多个从沟槽端来延伸的较小的辅助凸缘。此外,沟槽可在中心穿孔,从而围绕椭圆孔来形成一个连续且不中断的辅助凸缘,如图4E所示。在另一实施方式中,芯撑10可以在一个或二个主凸缘14中包括一个或多个沟槽18,配有一个或多个伸入芯撑10内的辅助凸缘20,如图17-19所示。图示的是一种单一的辅助凸缘20,从沟槽顶部32来延伸,从而形成凸缘从沟槽顶部、底部或侧面或者沟槽顶部、底部或侧面的组合来延伸的各种配置,所有这些均包括于本发明中。
辅助凸缘20形成于芯撑16上,从芯撑14上取出芯撑材料并折叠,从而形成沟槽18,芯撑材料数量与传统的金属芯撑相同。这样,上述各实施方式中辅助凸缘的尺寸便由所弯曲的沟槽尺寸来确定。这样,从二个沟槽侧来延伸的二个辅助凸缘便可各自成为沟槽的一半宽度。如果凸缘从矩形沟的各端来延伸,则侧面辅助凸缘的长度便缩小至等于顶部与底部辅助凸缘之和。如果在芯撑内保持同样数量的材料,则芯撑的支撑强度便不降低,事实上反而可增加支撑强度,如上述计算所示。
在图30-32所示的另一实施方式中,沟槽18包括穿过主凸缘14或芯撑16的多个孔,从而形成一列准锥形孔40,其从所述主凸缘14或芯撑16来延伸。图示的辅助凸缘14向外冲压;然而向内冲压的辅助凸缘也包括在本发明的实施方式中。为此,准锥形孔这一术语意味着孔的材料取自于所述凸缘或芯撑,其当孔穿过金属片时,从所述凸缘或芯撑围绕着孔而向外伸展,下凹曲面圆周边42在凸缘或芯撑上,从基座44向孔周46收窄,从而在其侧边42上与该凸缘或芯撑分离,因而形成对称的火山形状。
芯撑10还可通过连接辅助凸缘与卡环50来加强,从而在沟槽18上传递机械负荷,如图所示。U形卡槽52适配于从对侧孔来延伸的二个辅助凸缘14的远端54。卡板56穿过沟槽18,并由穿入卡槽52的孔60内的螺钉58来固定到卡槽52内。卡环的长处在于,其材料的传热及传声性最低。
各附图只用于说明本发明的各种实施方式。附图只用于说明,本限定本发明。图示的特性可以以其它方式或方式组合来实施。比如,一列环状沟槽包括于所有形状的沟槽中,而且不限于环状沟。同样,图示的是一种沟槽形状,配有一个辅助凸缘,从芯撑或主凸缘向内延伸,另一种沟槽形状或辅助凸缘同样从芯撑向外延伸。任何沟槽或辅助凸缘形状可向内或向外延伸,或者配置成其它附图所示的任何其它形状。
