  • the present invention belongs to the technical field of civil engineering and construction shock absorption, and relates to an assembled shock-absorbing filling wall of a frame structure, and specifically to a prefabricated assembled filling wallboard-frame structure with anti-shock absorption coordination and a construction method thereof.
  • the infill wall-frame structure is one of the main structural forms of buildings in my country. It is composed of beams, columns and infill walls, and has the advantages of flexible space division and light weight.
  • the infill wall is considered to be a self-supporting non-structural component that does not bear the vertical load of the main structure. Therefore, in the structural design, the infill wall is usually input into the beam as a line load, and the amplification effect of the infill wall on the lateral stiffness of the structure is approximately considered by using the periodic reduction method. However, this method is actually still based on the pure frame design, without considering the deformation and bearing performance of the infill wall.
  • the seismic performance of infill walls can be improved by setting vertical columns, horizontal tie beams, ribbed frames, tie bars in the infill walls, or by pasting carbon fiber cloth on the surface of the infill walls, or by applying new cement-based materials.
  • the existing technical solutions are aimed at damage control of infill walls and providing additional shock absorption capacity for the structure.
  • the infill walls are usually divided horizontally (or vertically) for multiple times to form shock-absorbing infill walls with multiple wall panel units.
  • Friction materials, viscoelastic layers or metal dampers and other materials (or elements) with energy dissipation and shock absorption are often set between the wall panel units. Under the action of horizontal earthquakes, the wall panel units will displace along the horizontal (or vertical) seams due to dislocation and deformation, thereby consuming energy.
  • the degree of wall assembly is low: As shown in FIG2, the shock-absorbing infill wall proposed in the prior art solution is usually composed of a plurality of wall panel units, and the wall panel units need to be formed by masonry blocks at the construction site. Therefore, the sliding joints between the wall panel units also need to be installed and laid at the construction site, which results in the disadvantage of low degree of wall assembly. Furthermore, compared with the vertical strip-type assembled panels that are currently more commonly used, the assembled shock-absorbing infill wall in the prior art solution usually uses horizontal panels, and the difference in the form of the panels will cause incoordination with the existing construction process.
  • shock-absorbing infill wall of the prior art solution is only suitable for building wall panels with smaller spans (such as staircase wall panels), and it is difficult to adapt to the current large-span and large-space building requirements.
  • the wall panel unit is usually only reliably connected to the frame body on one side, so the two-way deformation coordination of the shock-absorbing infill wall is not well considered:
  • the wall panel unit of the prior art solution due to the unique structural form of the transverse shock-absorbing wall panel unit of the prior art solution, it is possible to have out-of-plane displacement only under the in-plane action, which will bring great hidden dangers to the out-of-plane safety of the wall; in addition, the above phenomenon further shows that the out-of-plane bearing performance of the prior art solution is poor, that is, once the shock-absorbing infill wall is subjected to the coupling effect of in-plane and out-of-plane loads, the deformation and energy dissipation mechanism of the shock-absorbing infill wall along the sliding joint will be significantly changed, resulting in the problem of poor coordination of two-way deformation.
  • the purpose of the present invention is to overcome the shortcomings of the prior art and provide a prefabricated assembled infill wall panel-frame structure with anti-seismic coordination and a construction method thereof, which can ensure the use function of the building, improve the construction quality and assembly rate, and increase a certain lateral resistance capacity, while improving the two-way deformation coordination performance of the wall under in-plane and out-of-plane loads, and achieve multi-objective coordination of resisting seismic effects (seismic resistance), dissipating seismic input energy (shock absorption), reducing wall damage (damage control), and reducing structural residual displacement after an earthquake to reduce repair costs (recoverable).
  • the technical solution provided by the present invention is shown in FIG6 .
  • the technical solution is combined with the existing earthquake-resistant design method to set a small earthquake-resistant working state and a medium to large earthquake-reducing working state.
  • the prefabricated assembled infill wall panel and the main frame structure are in a small earthquake resistant working state, in which the structure maintains an elastic working state.
  • the prefabricated assembled infill wall panel group does not cause sliding hysteresis energy dissipation in the small earthquake resistant working state, so it can be equivalent to a double diagonal strut model in the main frame, which can provide a certain lateral stiffness for the structure, help limit the inter-story displacement angle, and ensure the normal use function of the structure.
  • the prefabricated infill wall panel and the frame body are mainly connected by flexible connection, it is helpful to realize the design concept of "strong column and weak beam".
  • strong column and weak beam When the wall slides and dissipates energy, the strong constraint effect between the infill wall and the frame is significantly released. The release of this effect will effectively alleviate the problems of significant stiffness mutation, large top displacement, excessive interlayer displacement and irregular torsion caused by the discontinuous vertical layout and uneven plane layout of the infill wall.
  • the prefabricated assembled filling wall panel proposed in the present invention will allow the wall panel to undergo a certain out-of-plane rotation at the bottom, while ensuring the wall damage control and out-of-plane bearing capacity, without affecting the in-plane sliding hysteresis energy dissipation performance of the wall panel, as shown in Figure 9.

Description

抗减震协同的预制装配式填充墙板-框架结构及施工方法 技术领域
本发明属于土木建筑减震技术领域,涉及框架结构的装配式减震填充墙,具体涉及一种抗减震协同的预制装配式填充墙板-框架结构及其施工方法。
背景技术
填充墙-框架结构是我国建筑的主要结构形式之一,由梁、柱及填充墙组成,具有空间分隔灵活、自重轻等优点。该结构形式中,认为填充墙是一种自承重的非结构构件,不承受主体结构的竖向荷载,因此在结构设计中通常将填充墙作为线荷载输入至梁,并采用周期折减的方式近似考虑填充墙对结构抗侧刚度的放大作用。然而,该方法实际仍基于纯框架进行设计,未考虑填充墙的变形及承载性能。
历次地震灾害报告表明,填充墙与框架主体结构协同受力、共同工作,往往充当地震下的“第一道防线”而发生较严重破坏,如图1所示,且填充墙与框架主体结构仍存在较强约束效应,易使主体结构出现短柱破坏,有悖于“强柱弱梁”设计理念的实现。填充墙破坏不仅是地震中经济损失的重要组成,也是影响建筑物使用功能快速恢复的重要原因。
目前,针对传统填充墙-框架结构在地震作用下的抗震性能研究已取得一定进展,通过在填充墙内设置竖向柱、水平系梁、密肋框架、拉结筋,或在填充墙表面粘贴碳纤维布、涂刷新型水泥基材料等方式均可提高填充墙的抗震性能。为进一步减小地震作用带来的生命、经济损失,现有技术方案以填充墙的损伤控制和为结构提供附加减震能力为目标,通常将填充墙进行多次横向(或竖向)分割以形成具有多墙板单元的减震填充墙,墙板单元间多设置摩擦材料、粘弹性层或金属阻尼器等具有消能减震的材料(或元件);水平地震作用下,墙板单元间因错动变形将沿横向(或竖向)缝发生错动而耗能。
综上所述,可以发现现有的研究与技术方案可提高填充墙的抗震性能,具有一定的减震效果,但上述技术方案仍存在以下问题需进一步考虑与解决:
1. 墙体装配程度低:如图2所示,现有技术方案提出的减震填充墙通常由多个墙板单元组成,所述墙板单元需在施工现场采用砌块砌筑成型,因此墙板单元间的滑动缝也需在施工现场进行安装铺设,存在墙体装配化程度低的不足。进一步的,相较于目前较多采用的竖条型装配式板材,现有技术方案中的装配式减震填充墙通常采用横向板材,而板材形式的不同将造成与现有施工工艺的不协同。特别地,如图3所示,当在较大跨度的框架内安装横向减震墙板单元时,往往较难实现横向减震墙板单元间的横向连续性拼接,因此现有技术方案的减震填充墙只适合较小跨度的建筑墙板(如楼梯间墙板),难以适配目前大跨度、大空间的建筑需求。
2. 结构抗侧能力弱:传统填充墙与框架主体往往具有可靠的连接以避免墙体发生面外倒塌,因此填充墙具备一定的抗侧能力,在实际地震作用下其与框架主体共同承担水平荷载。此外,合理考虑填充墙的抗侧能力仍有助于提高结构的韧性和减小主体结构构件的截面尺寸。然而,现有技术方案的减震填充墙的抗侧能力主要取决于墙板单元间滑动缝的减震层的剪切刚度,而该剪切刚度远小于传统墙体的抗侧刚度,因此当结构采用现有技术方案时其抗侧能力通常较弱。
3. 震后功能恢复难:在震后总修复成本中,用于修复震后填充墙、水电暖通管线的经济、时间成本通常占比较大,且恢复难度高。如前所述,现有技术方案通过在墙体不同高度处设置横向滑动缝将填充墙分割为多个墙板单元;然而,水电暖通管线往往被埋置于墙面内,当结构遭受地震作用时,墙板单元将沿横向滑动缝形成人工滑动裂缝,造成墙板面层和水电暖通管线发生损伤。此外,由于现有技术方案的减震填充墙在地震作用下发生滑动,所以地震后墙体的残余位移较大,难以快速恢复至地震前状态(图4)。
4. 双向变形协同差:实际地震中,填充墙总是同时受到面内和面外两个方向的耦合作用,面内损伤会影响面外承载力,面外损伤同样会影响面内行为。对于竖向减震墙板单元构造,其墙板单元通常上下均采用销轴连接或刚性连接,因此当有面内、面外荷载耦合作用时,墙板单元极易出现损伤。对于横向减震墙板单元构造,其墙板单元通常仅一侧与框架主体可靠连接,因此并未较好的考虑减震填充墙的双向变形协同:如图5所示,现有技术方案的横向减震墙板单元由于独特的构造形式,其仅在面内作用下就存在发生面外位移的可能性,这将对墙体的面外安全性带来极大隐患;此外,上述现象仍进一步表明现有技术方案的面外承载性能较差,即减震填充墙一旦受到面内、面外荷载的耦合作用,减震填充墙沿滑动缝的变形、耗能机制将被显著改变,造成双向变形协同差的问题。
发明内容
本发明的目的是为克服现有技术的不足,提供一种抗减震协同的预制装配式填充墙板-框架结构及其施工方法,能够在保证建筑使用功能、提高施工质量和装配率、增加一定抗侧能力的同时,提高墙体在面内、面外荷载作用下的双向变形协同性能,实现地震下抵抗地震作用(抗震)、耗散地震输入能量(减震)、降低墙体损伤(损伤控制)和地震后减小结构残余位移降低修复成本(可恢复)的多目标协同。
本发明提供的技术方案如图6所示,该技术方案结合现有抗震设计方法,设置小震抗震工作状态与中大震减震工作状态。
当预制装配式填充墙板-框架结构遭受小震地震作用时,预制装配式填充墙板与框架主体结构处于小震抗震工作状态,该状态下结构均保持弹性工作状态。如图7等效力学示意图所示,小震抗震工作状态下预制装配式填充墙板组不发生滑动滞回耗能,因此其在框架主体内可等效为双斜压杆模型,可为结构提供一定的抗侧刚度,有助于限制层间位移角,保证结构的正常使用功能。
如图8所示,当预制装配式填充墙板-框架结构遭受中大震地震作用时,填充墙板按刚度分配得到的层间剪力进一步增大,当墙板克服由碟簧组件最大预压力组成的临界起滑力后,墙板在框架主体带动下将沿底部减震层发生滑动滞回耗能,碟簧组件将发生往复压缩变形消耗少量地震输入能量,使结构进入中大震减震工作状态。中大震减震工作状态下,结构的整体抗侧刚度降低,地震输入能量减小,将有效避免墙体因承受过大层间剪力而发生墙体损伤与破坏。进一步的,由于预制装配式填充墙板与框架主体主要采用柔性连接,故有助于“强柱弱梁”设计理念的实现,当墙体发生滑动滞回耗能时,填充墙与框架间的强约束效应被显著释放,该效应的释放将有效缓解填充墙因竖向布置不连续和平面布置不均匀而造成的刚度突变显著、顶层位移大、层间位移超限和扭转不规则等问题。特别地,当墙体受到面内、面外荷载的双向耦合作用时,本发明提出的预制装配式填充墙板将允许墙板在底部发生一定的面外转动,在保证墙体损伤控制和面外承载力的同时,不影响墙板在面内的滑动滞回耗能性能,如图9所示。
地震作用后,现有技术方案的减震填充墙构造通常具有较大的震后残余位移 d 0,如图10中虚线填充墙-框架结构所示。当采用本发明提供的技术方案时,震后碟簧组件因处于受压状态可提供一定的恢复力,该恢复力将有效减小预制装配式填充墙板的震后残余位移 d 1,即 d 1< d 0
具体地,为实现上述工作原理与目的,本发明提供的抗减震协同的预制装配式填充墙板-框架结构,包括框架主体、预制装配式填充墙板组、墙板组卡件、碟簧组件和U型连接件,

步骤4:在预制装配式填充墙板组下部两侧安装碟簧组件;
步骤5:预制装配式填充墙板组与框架主体空隙进行柔性连接。
与现有技术相比,本发明的有益效果至少如下:
1. 提升墙体装配程度:抗减震协同的预制装配式填充墙板的核心单元通常可在预制工厂内批量化设计、生产、组装,预制装配式填充墙板组与框架主体的连接、安装顺序与现有装配式墙板施工工艺基本一致,因此能够最大化保证抗减震协同的预制装配式填充墙板的安装质量和效率。此外,一种抗减震协同的预制装配式填充墙板-框架结构中的墙板单元为竖条型墙板单元,单元间采用插接连接,有益于保证墙板单元间的拼接连续性,因此可在大跨度、大空间的建筑中应用。
2. 增加结构抗侧能力:抗减震协同的预制装配式填充墙板的碟簧组件为预压状态,所以只有当减震填充墙克服最大起滑力后才会沿减震层发生滑动滞回耗能,与现有技术方案相比,本发明能够为结构在滑动前提供相对较高的抗侧刚度以限制层间变形满足正常使用功能,实现小震抗震工作状态。
3. 提高震后可恢复性:抗减震协同的预制装配式填充墙板通过在预制装配式填充墙板组中的主板与副板间设置滑动减震层的方式耗散地震输入能量,与现有技术方案相比,本发明避免了在墙体中间开设多条滑动缝而影响建筑水电管线走线和建筑使用功能的缺点。此外,地震后碟簧组件通常处于被压缩状态故可提供一定的恢复力,降低墙体的残余位移;且相较于传统填充墙结构,预制装配式填充墙板与框架主体的连接以柔性连接为主,因此减震填充墙提供的抗侧刚度显著降低,有助于释放填充墙-框架的约束效应,实现“强柱弱梁”破坏机制,降低“短柱效应”及因填充墙板沿高度布置不连续而造成的刚度突变等问题。
4. 双向协同变形耗能:抗减震协同的预制装配式填充墙板-框架结构在面内、面外荷载的耦合作用下,其预制装配式填充墙板的主板与副板将沿半圆型凹槽和半圆形凸条间的减震层发生面-面均匀滑动,从而保证了墙体的双向协同变形耗能能力,解决了以往技术方案面外承载性能较低和双向变形协同差的难题。

实施例1:
如图6-图17所示,本实施例提供的一种预制装配式填充墙板-框架结构,包括框架主体,框架主体内安装预制装配式填充墙板组,框架主体包括框架顶梁1、框架底梁2、框架左柱3和框架右柱4,框架顶梁1与框架底梁2平行,框架左柱3与框架右柱4平行,框架顶梁1和框架底梁2的左右两端分别与框架左柱3与框架右柱4可靠连接。
预制装配式填充墙板组包括多个竖向子墙板,由左至右依次排列,包括分别位于左右外侧的左竖向墙板5、右竖向墙板7以及位于左竖向墙板5和右竖向墙板7之间的多个中间竖向墙板6,竖向子墙板的侧壁设置有插接凸条14或插接凹槽13,相邻竖向子墙板间通过墙板拼接粘结剂和插接凹槽13与插接凸条14的插接连接形成预制装配式填充墙板组整体单元。每个竖向子墙板均包括主板、减震层和副板,以左竖向墙板5为例,左竖向墙板5包括位于上方的左竖向墙板主板51、位于下方的左竖向墙板副板52以及位于左竖向墙板主板51和左竖向墙板副板52之间的减震层8,减震层8粘贴于左竖向墙板主板51底部的半圆形凹槽15和左竖向墙板副板52顶部的半圆形凸条16之间,半圆形凹槽15和半圆形凸条16可相互插接吻合,左竖向墙板主板51可沿所述左竖向墙板副板52顶部的半圆型凸条16发生一定转动。左竖向墙板5与框架底梁2间通过现浇细石混凝土11连接,左竖向墙板5与框架顶梁1间通过U型连接件12连接,U型连接件12与框架顶梁1间通过射钉连接,U型连接件12与左竖向墙板5仅前、后表面接触。多个中间竖向墙板6、右竖向墙板7与左竖向墙板5的构造基本一致,故不在赘述。
其中,每个副板的底部还设置有凸条,当现浇细石混凝土11凝结硬化后将与副板底部的凸条形成剪力键,墙板底部的剪力键与顶部的U型连接件12可有效限制墙板发生平面外位移,提高面外承载性能。
左竖向墙板5的左上部和右竖向墙板7的右上部与框架主体2的空隙通过墙板组卡件9连接,墙板组卡件9采用支模浇筑细石混凝土形成,呈L型。左竖向墙板5中左竖向墙板主板51的左下部与框架左柱3间、右竖向墙板7中主板71的右下部与框架右柱4间均安装有碟簧组件10,碟簧组件10包括碟簧盒101、碟簧102和碟簧垫板103,碟簧盒101通过射钉与框架主体连接,碟簧102为预压状态,碟簧垫板103与减震墙板组仅表面硬接触。
水平地震作用下,框架顶梁1发生水平位移并通过墙板组卡件9带动预制装配式填充墙板组发生从动滑移趋势。当预制装配式填充墙板组克服起滑力后,碟簧102被压缩变形,预制装配式填充墙板组中主板与副板沿减震层8发生滑移滞回变形,耗散地震输入结构的能量。水平地震作用后,预制装配式填充墙板组的震后残余位移使碟簧102处于受压状态,因此碟簧102可提供一定恢复力减小震后残余位移,降低快速恢复至震前状态的时间成本与经济成本。此外,当结构受到面外荷载作用时,预制装配式填充墙板的主板底部的半圆形凹槽15与副板顶部的半圆形凸条16将沿两者间的减震层8发生面-面均匀滑动,并产生一定的面外剪切耗能;当结构继续受到面内荷载作用时,由于半圆形凹槽15与半圆形凸条16仍保持均匀面接触,因此仍可在面内发生稳定的滑动滞回耗能,从而保证了墙体在面内、面外荷载耦合作用下的协同变形与耗能。
实施例2:
与实施例1基本相同,所不同的是:
减震层8选用SBS卷材或低强度砂浆等具有减震功能的材料。
所述框架主体为钢筋混凝土框架或钢框架。
实施例3:
本实施例公开前述实施例提供的一种预制装配式填充墙板-框架结构的施工方法,如图18-图20所示,预制装配式填充墙板组安装前,应首先完成框架主体的施工,清理框架顶梁及框架底梁的碎渣及杂物,并进行基面找平处理;随后对照施工图纸,在墙板安装位置弹出墙板安装位置线,标明墙板的安装位置。
所述预制装配式填充墙板-框架结构的施工方法包括以下步骤:
步骤1:
根据预先标明的墙板安装位置,在左竖向墙板5定位后,于其顶部安装U型连接件12,并在其底部插入木楔,安装示意图如图18所示;安装时,采用靠尺调整墙面垂直度,使墙板下边缘与墙板安装位置线重合,以确保墙板的垂直度和平整度符合标准、规范要求。
步骤2:
重复步骤1工序,依次将若干中间竖向墙板6、右竖向墙板7安装拼接,拼接时,相邻竖向子墙板间先在插接凹槽13内涂刷墙板拼接粘结剂,随后插接插接凹槽13与插接凸条14,以拼接组成预制装配式填充墙板组整体单元。
步骤3:
预制装配式填充墙板组拼接完成后,在其底部与框架底梁2顶部的空隙内浇筑细石混凝土,浇筑时应保证底部现浇细石混凝土11完全填充所述空隙,并使细石混凝土在预制装配式填充墙板组与框架左柱3、框架右侧柱4间的空隙浇筑高度与副板51和副板71顶部平齐,空隙浇筑高度示意图见图16;进一步的,待底部现浇细石混凝土11凝结硬化后,抽出底部木楔并在木楔遗留孔洞处填塞细石混凝土;进一步的,在预制装配式填充墙板组的左上部与右上部分别支模浇筑细石混凝土以形成墙板组卡件9;进一步的,分别在左竖向墙板5和右竖向墙板6的靠近框架主体一侧的底部安装碟簧组件10,所述碟簧组件10的具体安装位置示意图见图6、图16。
步骤4:
预制装配式填充墙板组与框架主体的其他空隙根据防潮、隔音、保温需求采用合适的柔性连接材料进行填塞、填缝处理。
上述虽然结合附图对本发明的具体实施方式进行了描述,但并非对本发明保护范围的限制,所属领域技术人员应该明白,在本发明的技术方案的基础上,本领域技术人员不需要付出创造性劳动即可做出的各种修改或变形仍在本发明的保护范围以内。
