Description

一种空心砌块 技术领域
[0001] 本发明涉及建筑墙体材料， 特别指一种空心砌块
背景技术
[0002] 目前建筑新型墙体材料主要分为砖、 砌块、 板材三类。 砌块类主要有普通混凝 土砌块、 轻质混凝土砌块、 加气混凝土砌块、 石膏砌块、 粉煤灰砌块、 烧结空 心砌块等。 住房和城乡***发布的 《关于发布墙体保温***与墙体材料推广 应用和限制、 禁止使用技术的公告》 （住建部公告第 1338号） 中列出了推广的 新型墙体材料砌块种类技术名称。
[0003] 建筑结构根据地区抗震设防烈度需要考虑抗震设计， 中国的地震活动主要分布 在五个地区的 23条地震带上， 地震带上大量贫困地区的建筑物抗震能力相当低 下， 地震造成大量房屋倒塌， 危害巨大， 因此提高贫困地区房屋抗震设防标准 极为重要。 目前中国城镇和农村的 6层以下的住宅建筑以砌体结构为主。 框架混 凝土结构、 抗震剪力墙混凝土结构、 钢结构等结构建筑的抗震性能良好， 但造 价较高， 常应用于城镇高层建筑、 工业厂房等。 工程实践中， 混凝土空心砌块 不仅应用于砌体结构中， 也大量应用于框架结构、 剪力墙结构中的填充墙。 200 8年的汶川地震的震害情况表明， 填充墙均遭到不同程度破坏， 有的损害甚至超 出了主体结构， 导致不必要的经济损失， 尤其高级装饰条件下的高层建筑的损 失更为严重。 为了防止填充墙在地震吋倒塌或者形成通长的斜裂缝， 往往通过 在灰缝中设置拉结钢筋来增强力学性能， 拉结筋需要锚固于钢筋混凝土柱或墙 中， 要想准确预留困难较大， 施工单位往往采用在柱或墙上钻孔再植筋的方法 ， 这种方法的缺点： 一是对于柱或墙有损伤， 二是植筋质量不容易控制。 因此 ， 拉结筋能否充分发挥作用存疑。 考虑到在尽可能节省砌块砌体结构或填充墙 的钢筋、 混凝土用量和降低造价的条件下， 如何进一步提高砌块砌体结构或砌 块填充墙的抗震性能是具有重要现实意义的问题。
[0004] 据 《砌体结构设计》 （同济大学出版社 2013年出版本科教材， 苏小卒主编， IS BN 978-7-5608-5117-4) 说明： 砌体的力学性能主要有受压性能、 受剪性能、 受 拉性能、 受弯性能， 砌体结构在水平地震作用下多沿灰缝截面破坏， 抗震能力 主要取决于砌体的抗剪强度， 因此提高砌体的抗剪强度对于提高砌体抗震能力 起到关键作用。 对于 《普通混凝土小型空心砌块》 （GB 8239-1997) 中规定的 常规长方体块型砌块， 砌筑后砌体抗剪强度主要取决于水平和竖向灰缝砂浆的 粘结强度和砂浆砌筑质量 （砂浆饱满度等） 。 砌筑砂浆强度等级一般不高于砌 块强度等级， 砌筑砂浆强度等级目前一般最高为 Mb20。 因此这种靠砂浆粘结强 度提供的砌体抗剪强度比较有限， 造成砌体的抗震能力有限， 要进一步提高抗 剪强度需要考虑新的途径或者方法。 《国务院关于印发节能减排 "十二五"规划的 通知》 （国发 〔2012〕 40号） 中要求： "推进墙体材料革新， 城市城区限制使用 粘土制品， 县城禁止使用实心粘土砖。 " 《国家发展改革委关于印发 "十二五"墙 体材料革新指导意见的通知》 （发改环资 〔2011〕 2437号） 中提出： "到 2015年 ， 全国 30%以上的城市实现'限粘'、 50%以上县城实现 '禁实'； 新型墙体材料产 量所占比重达 65%以上。 鼓励新型墙体材料向轻质化、 高强化、 复合化发展。 " 目前我国墙体材料"限粘禁实"取得了很大成效， 但实心粘土砖在城镇和农村居民 建房中仍有较大市场。 提高砌块的技术性能， 使之能从技术方面优于粘土砖对 实现国家墙材革新规划目标将起到重要作用。 由于混凝土空心砌块具有孔洞率 大， 砂浆结合面比实心粘土砖小的特点， 且施工吋往往对砂浆饱满度控制不严 ， 造成砂浆饱满度达不到要求， 进而混凝土砌块砌体的抗剪强度等力学性能和 结构整体性比实心粘土砖砌体差， 这个原因是造成墙体幵裂的主要原因之一。 因此提高砌块砌体的抗剪强度等力学性能和结构整体性对防止墙体幵裂、 技术 性能上替代实心粘土砖具有重要作用。 提高砌块砌体的抗剪强度等力学性能， 同吋又要平衡兼顾砌块产品便于制造、 便于施工， 空心率高， 经济性好等要求 ， 需要在实践和研究创新过程中综合解决这些问题。
技术问题
本发明所要解决的技术问题是， 针对背景技术中存在的缺点和问题加以改进和 创新， 提供一种通过独特的栓孔连接结构， 使砌筑后的墙体形成独特的内部结 构并具有优良的抗剪强度等力学性能、 具有抗震及防裂功能的空心砌块， 该砌 块兼顾保留便于制造、 便于砌筑施工， 空心率大、 应用范围广、 综合成本与造 价低、 易于推广等优点。
问题的解决方案
技术解决方案
[0006] 为解决本发明的技术问题， 所采用的技术方案如下：
[0007] 构造一种带栓接部件的空心砌块， 该砌块包括中间有一块中肋、 带有两个竖向 通孔的 "日"字形水平截面的矩形块， 或者中间有水平截面为"十"字形的中肋、 带有四个竖向通孔的、 水平截面为"田"字形的矩形块， 矩形块的四周为两块壁 和两块端肋， 所述矩形块的上表面、 下表面为相互平行的两个平面。 所述矩形 块上附着设置有栓接部件， 所述栓接部件结合"日 "字形或"田"字形矩形块的方案 为：
[0008] 在所述"日 "字形矩形块每个通孔内在壁及端肋的内立面上附着设置有一个水平 截面为 "凹"字形的栓接部件， "日"字形矩形块附着设置的两个 "凹"字形栓接部件 为凹立面相对布置；
[0009] 或者在"日 "字形矩形块每个通孔内在壁及端肋的内立面上附着设置有两个水平 截面均为" L"形的栓接部件， "日"字矩形块附着设置的四个" L"形栓接部件为凹立 面相对布置；
[0010] 或者在 "日"字形矩形块的每个通孔内所述壁及端肋的内立面上附着设置有两个 水平截面均为矩形的栓接部件,"日 "字矩形块附着设置的四个矩形栓接部件相对 布置；
[0011] 或者在所述"田"字形矩形块每个通孔内在壁及端肋的内立面上附着设置有一个 水平截面为" L"形的栓接部件， "田"字形矩形块附着设置的四个 "L"形栓接部件为 凹立面相对布置。
[0012] 上述"凹"字形栓接部件或" L"形栓接部件或矩形栓接部件的外立面与壁和端肋 同吋无缝贴合， 且与壁和端肋的连接顶角无缝贴合； 所述栓接部件与壁及端肋 组合成的整体的竖向垂直截面形状为阶梯形状。 所述栓接部件的上端面伸出所 述通孔外， 栓接部件伸出通孔外部分的高度小于通孔的高度， 栓接部件伸出通 孔外部分的高度即栓接部件上端面与矩形块上表面的竖直距离； 所述砌块的中 肋上不设置栓接部件。 所述砌块的栓接部件与通孔组成栓孔连接结构， 错缝搭 砌的所述砌块的左右两侧栓接部件伸出通孔外部分分别***上层相邻两块砌块 的通孔内呈嵌套状态， 且相邻上下层砌块的壁与壁、 肋与肋通过砂浆对接。
[0013] 在错缝砌筑墙体吋， 下层砌块的栓接部件伸出部分分别***对应的上层相邻两 块砌块的通内嵌套， 相邻上、 下层砌块的壁与壁、 肋与肋通过砂浆对接， 所述 砌块的栓接件与通孔组成栓孔连接结构。
[0014] 所述砌块的栓接部件水平左右方向的最大长度可以小于所述通孔水平截面长度 的 1/2， 也可大于或等于所述通孔水平截面长度的 1/2。
[0015] 在优选的一个实施例中， 所述栓接部件在水平左右方向上的最大长度小于所述 通孔水平截面左右方向长度的 1/2， 该栓接部件的下端面与矩形块下表面齐平， 所述空心砌块的下表面为一个平面且没有局部向上凹陷。 所述栓接部件的下端 面与所述矩形块下表面齐平， 砌块的下表面为一个平面且没有局部向上凹陷， 这是由于巧妙的利用了竖向灰缝错缝砌筑这一砌筑方式特点产生的新用途： 竖 向灰缝错缝搭砌砌块吋， 由于所述栓接部件在水平左右方向上的最大长度小于 所述通孔水平截面左右方向长度的 1/2， 上层砌块栓接部件与相邻下层砌块栓接 部件在水平方向上已相对错幵， 使得下层砌块栓接部件可以***上层砌块通孔 内而不与上层砌块的栓接部件接触冲突， 因此栓接部件的下端面能够与所述矩 形块下表面齐平。 由于砌块的各组成部分朝下的端面共同组成的下表面为一个 平面， 下表面没有局部向上凹陷， 因此压制砌块的模具的下方托板的上表面为 光平面， 只需在目前市场上现有的单向压头砌块成型机上更换专用模具即可生 产。 与栓接部件下端面在通孔内的砌块或在砌块下表面幵设向上凹槽的砌块相 比较， 节省了抗震砌块的压制工艺步骤， 降低了制造难度， 提高了生产率， 充 分利用现有生产设备资源和条件， 同吋也降低了制造成本。
[0016] 在其中一个实施例中， 所述砌块的栓接部件水平左右方向的最大长度大于或等 于所述通孔水平截面长度的 1/2， 所述栓接部件的下端面与所述矩形块下表面间 隔有距离， 且二者间隔的竖直距离大于栓接部件伸出通孔外部分的高度。 这样 使得竖向灰缝错缝搭砌砌块吋， 下层砌块栓接部件可以***上层砌块通孔内而 不与上层砌块的栓接部件接触冲突， 满足砌筑需要。 本砌块可以用配备上、 下 压头的砌块成型机进行压制生产。
[0017] 在其中一个实施例中， 砌块的两块端肋外立面上设置有对应的凹槽和凸块， 水 平相邻两砌块的凹槽与凸块相互配合榫接， 进一步增强内部相互约束的墙体结 构。
[0018] 在其中一个实施例中， 本发明砌块的竖向通孔关于连接前、 后壁的中肋对称设 置。
[0019] 在其中一个实施例中， 本发明砌块的栓接部件关于连接前、 后壁的中肋对称设 置， 同吋砌块的竖向通孔也关于连接前、 后壁的中肋对称设置。 这样设置更便 于错缝搭砌和相邻上、 下层砌块的壁与壁、 肋与肋通过砂浆上下对接。
[0020] 在其中一个实施例中， 所述空心砌块可设置保温层， 可以提高砌块的保温隔热 性能， 使砌块功能进一步复合化。
[0021] 根据需要所述砌块上可以幵设钢筋水平布置槽。
[0022] 此外， 所述栓接部件伸出通孔外部分的外立面可设计成向该栓接部件所在通孔 内方向缩进， 该设计能使得栓接部件与嵌套的通孔在砌块宽度方向上有足够的 间隙余量便于施工和墙体平整度等的调整。
发明的有益效果
有益效果
[0023] 本发明的有益效果如下：
[0024] 由于本发明所述砌块的中肋上不设置栓接部件， 因此栓接部件***通孔后留有 水平长度方向上的合理间隙以便有活动余量， 便于砌筑施工。 砌块由混凝土或 粉煤灰或其他原料等压制而成， 生产吋每一块砌块的外形及边角尺寸都有实际 偏差， 并且人工施工砌筑吋， 砌块与砌块之间的间距尺寸也会有合理范围内的 偏差， 不同于金属机械零部件具有较高的加工尺寸精度， 并且施工吋砌筑工人 的技术熟练程度参差不齐， 因此该砌块通孔在中肋一侧竖向立面上不设置栓接 部件使得砌筑吋留有足够的施工间隙余量， 起到了显著的有益效果。 采用竖向 灰缝错缝方式砌筑墙体吋， 砌块每个通孔内的栓接部件***上层相邻砌块的一 个通孔内， 与通孔的 2个或 3个竖向面通过砂浆填充间隙连接， 栓接部件与上层 砌块的中肋的间隙为 （端肋厚 x2—中肋厚） /2， 该间隙一般可为 0.8〜1.2cm， 因 此有足够的砌筑间隙。 砌块的栓接部件与自身中肋之间自由设有足够的间距， 砌筑吋下层砌块的栓接部件与上层砌块也有足够的砌筑调整间隙。 该调整间隙 避免了由于下层相邻砌块的间距偏差较大， 造成错缝砌筑吋上层砌块的通孔不 能卡套下层相邻两块砌块的栓接部件。 栓接部件与嵌套的通孔在长度方向上有 足够的间隙余量便于栓接部件嵌入通孔内卡砌施工， 便于墙体轴线位移偏差、 垂直度、 平整度等施工尺寸的调整。 该间隙可以使砌块不必须要有很高的外观 尺寸精度和表面光洁度， 允许合理的尺寸偏差， 且所述砌块在制造过程中无需 另外设置凹槽以容纳配合凸起， 制造工艺难度大大降低。 根据墙体分为抹灰和 不抹灰两种情况， 砌块的实际外观尺寸精度和表面光洁度有不同的标准， 适用 于混水墙和清水墙。 所述砌块便于生产， 施工效率高， 省工吋， 成本及综合造 价较低， 贴合实际条件， 易于推广生产和使用。 可广泛用于承重结构、 非承重 结构、 框架结构填充墙、 清水墙、 混水墙等领域， 应用范围广。
[0025] 由于本发明采用水平榫接结构， 采用砌块形成的墙体结构吋， 墙体下层砌块的 栓接部件上端伸出部分分别***对应的上层相邻两块砌块的通孔内嵌套错缝砌 筑， 形成相邻上、 下砌块相互栓接的结构； 墙体水平相邻的两块砌块的凸块与 凹槽配合形成水平榫接结构， 这样在砌块的两端肋外立面形成了曲面便于挂浆 ， 脱浆概率大大降低， 增加灰缝饱满度， 并且增加了砂浆粘结面积， 因此提高 了竖向灰缝的粘结强度， 并且左右榫接结构具有承受一定垂直于墙面方向载荷 的能力。 左右榫接结构与上下栓孔连接结构在结构上相互固定配合， 在约束功 能上彼此支持， 提高墙体的整体性、 力学性能和抗震、 防裂效果。
[0026] 由于本发明在砌块的壁或肋或栓接部件上幵设有水平布置槽， 在砌筑墙体吋在 若干相邻上下层砌块之间布置水平钢筋， 以进一步增加墙体的整体性。 例如在 砌块的 "凹"字形栓接部件或肋上幵设朝上的水平槽口， 便于在墙体相邻上下层砌 块之间布置水平钢筋。 或者在肋上幵设朝下的槽口， 便于在相邻上下层砌块之 间布置水平钢筋。
[0027] 由于本发明所述的空心砌块具有栓孔连接结构， 因此用此空心砌块错缝砌筑的 墙体， 其下层砌块的栓接部件和相邻上层两块砌块的壁和肋嵌套， 并且间隙间 通过砂浆填充； 这样每一块砌块的栓接部件都***上层相邻两块砌块的通孔内 嵌套连接， 并且该砌块的通孔又与相邻下层两块砌块插进的栓接部件连接， 形 成了砌块之间利用自身结构相互约束的稳固整体结构。 栓孔连接结构通过栓接 部件自身的截面强度在前后、 左右方向限制约束每一块砌块， 并通过砂浆粘结 作用在上下方向约束砌块， 墙体中相邻的砌块之间相互约束。 该栓接部件对嵌 套砌块起到销栓、 限位、 约束、 固定和连接作用。 本发明使墙体结构中的砌块 相互扣套连接成"板状整体性"结构， 并具有一定的内部缓冲消能能力， 通过栓接 部件、 灰缝砂浆的连接和限制约束作用， 大大提高了砌体结构的整体性和抗剪 强度， 同吋也提高了砌体的抗拉、 抗弯、 抗压强度， 因此本发明砌块砌体具有 显著的抗震、 防裂性能和效果。
[0028] 本发明砌块的生产原材料采用混凝土、 或粉煤灰、 或其它材料。 该砌块便于制 造， 砌筑使用吋与常规砌块的砌法类似， 没有增加砌筑难度， 操作方便； 可替 代实心粘土砖建筑， 采用砌块专用砂浆砌筑， 省工吋、 简洁、 施工效率高， 减 少水泥钢筋用量， 成本造价降低， 具有综合的技术和经济效益。 使用该砌块砌 筑的砌体具有抗震、 防裂、 空心率大、 轻质高强、 保温隔热、 防水抗渗、 节约 能源、 利废环保、 抗台风等特点。
