Description

一种门式脚手架 本申请要求于 2009 年 04 月 30 日提交中国专利局、 申请号为 200920152307.8、 发明名称为 "一种门式脚手架"的中国专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及一种建筑工具， 特别涉及一种门式脚手架。 背景技术
当前， 在建筑施工中， 往往需要搭设适当的脚手架， 以便于在高处进 行施工作业。 其中， 门式脚手架因为具有搭建和拆除方便、 高效的特点而 被广泛应用。
门式脚手架一般包括门架和大横杆； 门架包括门架横杆和两个立杆， 门架横杆两端分别与两个立杆固定， 形成一个门架框； 在安装脚手架时， 在纵向方向， 用适当的大横杆将多片门架连接固定； 在垂直方向， 用适应 的结构使多片门架固定， 从而形成具有适当强度和尺寸的脚手架， 施工人 员可以在脚手加相进行建筑施工作业。 由于门架作为门式脚手架的一个单 元， 能够大大减少的脚手架的零部件数量， 因此， 门式脚手架的运输和安 装非常方便， 效率也非常高。
当前， 为了提高门式脚手架搭建与拆除的方便性和高效性， 人们对门 式脚手架的零部件进行标准化和系列化设计； 这样， 在搭建门式脚手架时， 可以根据实际需要选择适当型号的门架和大横杆， 就能形成合适高度的门 式脚手架， 满足建筑施工的需要。
为了保证大横杆与门架的连接， 现有技术中， 大横杆与门架连接处具 有特别制作的连接机构。 虽然现有技术中的连接机构能够实现大横杆与门 架之间的连接， 但也存在一定的问题： 大横杆与门架之间的连接机构增加 了脚手架的制造成本； 同时， 连接机构也使脚手架的搭建与拆除过程更繁 瑣， 降低了脚手架搭建与拆除的工作效率； 另外， 连接机构也使大横杆与 门架之间形成一个非刚性的铰接点， 进而削弱了门式脚手架的强度和稳定 性。 由于现有的门式脚手架存在强度和稳定性的不足， 因此， 需要在门式 脚手架的各个工作面上铺设脚手板， 以增加门式脚手架的强度和稳定性； 然而， 在外墙施工过程中， 两步距的作业层就能够满足作业面的要求， 在 每一个工作面上铺设脚手板显然造成了脚手板的浪费； 同时， 每一步距都 铺设脚手板还会纵容施工作业人员任意在脚手板上堆放建筑材料， 这进而 非常容易使脚手架负载过大， 进而影响施工安全。
另外， 在建筑施工过程中， 当存在阳台、 空调板或挑栏时， 建筑物表 面会存在外凸结构； 利用现有技术提供脚手架， 在大横杆的长度与外凸结 构不相匹配时， 就需要使用多种型号或长度的大横杆进行配合， 才能使脚 手架与建筑物表面的外凸结构相匹配； 这样就需要准备多种长度的大横 杆， 增加设备库存量， 进而使施工用料的管理难度增加， 提高了建筑成本。 而且， 用多种型号或长度的大横杆配合， 也难以保证脚手架与作业面之间 具有合适的距离； 在门式脚手架与作业面之间距离不合适时， 会使施工作 业非常困难。 发明内容
针对上述缺陷， 本发明的目的在于， 提供一种成本低、 搭建与拆除效 率更高的门式脚手架。
本发明提供的门式脚手架包括竖向布置的门架和横向布置的大横杆， 所述门架包括由门架横杆和两个立杆组成的门架框， 所述门架横杆两端分 别与两个立杆固定， 所述门架还包括扣件， 所述扣件将大横杆与门架框固 定，以通过调整所述大横杆与门架框的固定位置调整所述门架之间的距离。
优选地，所述门式脚手架还包括用绑扎带与所述大横杆固定的小横杆。 优选地， 所述门架还包括与所述门架框固定的遮蔽件， 所述扣件在水 平面上的投影位于所述遮蔽件在水平面上的投影内。
优选地， 所述扣件与门架横杆固定； 所述门架包括垂向上相邻的上门 架和下门架， 所述上门架的所述遮蔽件与所述下门架的所述扣件相对。
优选地， 所述遮蔽件为槽钢， 所述槽钢的开口朝下。
优选地， 其特征在于， 所述大横杆的上方固定有小横杆， 以形成工作 层； 所述工作层的上平面的高度与所述遮蔽件的上平面的高度相等。 优选地， 所述门式脚手架还包括用绑扎带与所述立杆固定的护栏杆。 优选地， 所述门架包括在纵向上相邻的第一门架和第二门架， 所述第 一门架的宽度小于第二门架的宽度， 所述大横杆包括第一内大横杆， 所述 第一内大横杆从第一门架的扣件中伸出， 与第二门架的门架横杆固定。
优选地， 所述第一内大横杆与第二门架的门架横杆通过绑扎带固定。 优选地， 所述的绑扎带为塑料绑扎带。
与现有技术相比， 本发明提供的门式脚手架中， 大横杆与门架框通过 扣件固定， 大横杆可以是普通的钢管或其它建筑材料， 不需要特别制作连 接机构， 从而降低门式脚手架的制造成本； 同时， 通过扣件固定大横杆的 方法非常简单， 进而使门式脚手架的搭建与拆除更加简便， 进一步地提高 了门式脚手架搭建和拆除的工作效率。 另外， 在建筑物存在外凸结构时扣 件可以在适当的位置将大横杆与门架固定， 门架之间的距离可以根据需要 进行调整， 因此， 不需要多种型号的大横杆配合， 就可以使搭建的门式脚 手架能够与建筑物纵向尺寸相适应， 不需要准备多种型号的大横杆， 进而 减少门式脚手架零部件的库存量， 降低施工用料的管理难度。
在进一步的技术方案中， 所述门架还包括遮蔽件， 并且所述扣件在水 平面上形成的投影位于所述遮蔽件在水平面上形成的投影内； 因此， 施工 过程中， 遮蔽件拦截由上方落下的沙浆， 避免扣件粘连沙浆， 进而使门式 脚手架的拆除更加方便。
在进一步的技术方案中， 通过扣件将大横杆与门架横杆固定， 且使上 门架的所述遮蔽件与下门架的所述扣件相对， 这样的技术方案使门架横杆 与遮蔽件分别位于门架的上部和下部， 遮蔽件不仅具有拦截沙浆的功能， 还能够增加门架的强度， 进而增加门式脚手架的强度。
在进一步的技术方案中， 所述遮蔽件为开口向下的槽钢， 能够更好地 避免扣件粘连下落的沙浆， 从而在施工过程中更好地使扣件保持表面的清 洁； 防止由于粘连沙浆而造成门式脚手架拆除困难。 另外， 用槽钢作为遮 蔽件， 还有利于增加门架的刚度。
在进一步的技术方案中， 在由小横杆组成的工作层中， 所述小横杆上 侧边， 即工作层的上平面的高度与所述遮蔽件的上平面的高度相等， 这就 为脚手板的铺设提供便利。
在进一步的技术方案中， 所述门架包括宽度不同的第一门架和第二门 架， 在搭建门式脚手架时， 与第一门架固定的第一内大横杆的一端延伸到 第二门架的门架横杆上， 并与第二门架的门架横杆固定， 由于第一内大横 杆与第二门架固定位置可以根据建筑物的外凸结构进行调整， 这样很方便 地使门式脚手架适应建筑物的外凸结构； 同时， 可以减少备用的零部件种 类， 进而进一步地减少门式脚手架零部件的库存量， 简化对施工用料的管 理。

具体实施方式
本部分的描述仅是示范性和解释性， 不应对本发明的保护范围有任何 的限制作用。
应当说明的是： 本文中， 以使用门式脚手架的建筑物为参照， 所述纵 向为在水平面内， 与建筑物主要施工表面平行的方向； 所述横向为与建筑 物主要施工表面垂直的方向； 所述垂向为与水平面垂直的方向。
实施例提供了一种门式脚手架， 该门式脚手架包括门架 1和大横杆 2。 请参考图 1 , 图 1是实施例提供的门架的主视方向结构示意图； 门架 1 包 括门架框， 门架框包括两个立杆 11和一个门架横杆 12; 两个立杆 11走向 基本平行， 门架横杆 12两端分别与两个立杆 11 固定； 在搭建的门式脚手 架中， 门架横杆 12横向布置。 本领域技术人员可以理解， 门架框还可以有 多种具体的结构， 为了增加门架 1的强度和稳定性， 还可以设其它能够增 加强度的结构； 本例中就设有两个斜拉杆 15 , 每一个斜拉杆 15两端分别 与门架横杆 12和一个立杆 11 固定； 还可以设多个门架横杆 12和 /或多个 立杆 11 , 等等。
在纵向方向上， 门式脚手架通过大横杆 2将多片门架 1联结起来。 结 合图 1和图 2 , 图 2是实施例提供的扣件的结构示意图， 门架 1包括扣件 13 , 扣件 13包括扣箍条 132和两个紧固部 131 , 两个紧固部 131分别位于 扣箍条 132两端， 紧固部 132与门架横杆 12固定； 扣箍条 132向上弯曲， 在扣箍条 132与门架横杆 12之间形成适当的空间， 以使大横杆 2穿过，将 大横杆 2固定在扣箍条 132与门架横杆 12之间；在大横杆 2连续穿过多片 门架 1时， 就将多片门架 1连成一个整体。 由于且大横杆 2与门架 1之间 的连接点为刚性连接点， 因此， 形成的门式脚手架的强度和稳定性得到很 大提高。 本例中， 一片门架 1包括两个扣件 13 , 因此一个门架 1与两个大 横杆 2固定相连。 两个大横杆 2纵向延伸， 且延伸方向基本平行； 为了增 加两个大横杆 2之间的跨距， 使搭建后的门式脚手架具有更强的稳定性， 两个扣件 13可以分别靠近门架横杆 12的两端。可以理解，在特定情况下， 也可以在门架横杆 12上设多个扣件 13 , 这样， 在搭建门式脚手架时， 可 以根据实际需要， 使门架 1与多个大横杆 2固定， 以增加门式脚手架的稳 定性能； 扣件 13也不限于与门架横杆 12固定， 也可以与立杆 11固定； 为 了保持大横杆 2与门架 1之间固定的可靠性，可以用紧固件将扣件 13与门 架横杆 12固定， 使扣箍条 132与大横杆 2之间保持适当的作用力。
在垂向方向上， 多片门架 1通过自身适当的结构联结成起来。 如图 1 所示， 门架 1的立杆 11上端具有插头 111 , 下端具有插头座 112, 本例中， 立杆 11为钢管， 插头 111为一直径稍小于钢管内径的圓柱钢筋， 下端内孔 形成插头座 112。参考图 3和图 4, 图 3是实施例提供的门式脚手架的横向 剖视结构示意图， 图 4为图 3中门架连接处的 I一一 I部分放大图。 为了描 述方便， 可以将位于上方的门架 1 称为上门架 101 , 将位于下方的门架 1 称为下门架 102。 在搭建门式脚手架时， 下门架 102的两个立杆 11上端的 插头 111分别与上门架 101的立杆 11下端的插头座 112相配合，从而使上 门架 101和下门架 102连结起来； 在垂向方向上， 多片门架 1依相同的方 式可以结合成一个相对固定的整体。可以理解，将上门架 101和下门架 102 固定在一起的方式不限于上述结构， 可以使立杆 11的下端为插头 111 , 上 端为插头座 112; 也可以在两片门架 1的立杆 11之间设其它的连接结构， 将上门架 101和下门架 102固定在一起。
由于在纵向和垂向方向上， 多片门架 1相对固定， 形成的门式脚手架 就能够保持适当的稳定性和强度， 为建筑施工作业提供便利。 本领域技术 人员可以理解， 为了增加门式脚手架的稳定性和可靠性， 还可以根据实际 施工需要设适当的连墙杆和斜拉杆。 本发明提供的门式脚手架中， 大横杆 2与门架横杆 12通过扣件 13固定， 大横杆 2两端与门架 1之间无需设其 他特定的连接机构， 从而能够降低门式脚手架的制造成本； 同时， 通过扣 件 13固定大横杆 2的方法非常简单，使门式脚手架的搭建与拆除过程非常 简便， 进而提高门式脚手架搭建和拆除的工作效率。 另外， 扣件 13可以根 据实际需要， 在适当的位置将大横杆 2与门架 1固定， 门架 1之间的距离 可以根据需要进行调整， 不再受限于大横杆 2的固定长度， 因此， 不需要 多种大横杆 2配合， 就可以很容易地使搭建的门式脚手架与建筑物 100纵 向尺寸相适应， 降低门式脚手架的搭建难度。
由于本发明提供门式脚手架具有较大的强度和稳定性， 就不需要通过 在各个工作面上铺设脚手板的方式增加门式脚手架的强度； 可以根据实际 需要在在适当的位置铺设脚手板。 在进行外墙施工时， 只需要铺设两步距 的脚手板就能够对相应作业面进行施工作业， 从而大大减少脚手板使用 , 降低建筑成本； 同时， 由于铺设的脚手板较少， 也促使施工人员及时清理 建筑材料， 避免在脚手板上随意堆放建筑材料， 减少门式脚手架负载， 进 而消除门式脚手架潜在的安全隐患。
本领域技术人员可以了解，在施工过程中， 不可避免地会有沙浆下落； 沙浆下落过程中， 必然会落在门式脚手架上。 在沙浆落在扣件上时， 由于 扣件 13所在的部分凹凸不平， 沙浆硬化后很难进行清理； 而且， 硬化后的 沙浆还会影响门式脚手架的拆除和下一次的搭建； 在用紧固件连接扣件 13 和门架横杆 12时， 落下的沙浆会使紧固件难以松动， 同样会造成门式脚手 架的拆除和下次安装的困难。
为了避免上述情况的发生， 在门架 1下部还可以设遮蔽件。 如图 1所 示的实施例提供的门架的主视方向结构示意图， 遮蔽件为开口向下的槽钢
14。 参考图 3和图 5 , 图 3是实施例提供的门式脚手架的横向剖视结构示 意图， 图 5是图 3中门架连接处的 A A剖视结构示意图。槽钢 14位于 门架 1的下部，门架横杆 12位于门架 1的上部；在门式脚手架搭建完毕后， 位于上方的门架 1的槽钢 14正好在下方的门架 1的扣件 13上方， 且扣件 13在水平面上的投影位于槽钢 14在水平面上的投影内； 这样， 在施工过 程中， 槽钢 14就将扣件 13罩住， 使沙浆不能达到扣件 13上， 从而避免扣 件 13粘连沙浆， 进而使扣件 13保持清洁， 避免拆卸和下一次安装时的困 难。 本例中， 槽钢 14还与大横杆 2的相接触， 在上方部件的重力作用下， 槽钢 14对大横杆 2施加适当的作用力，将大横杆 2卡住，使大横杆 2不能 在纵向上滑动。 根据上述描述， 本领域技术人员还可以釆用其它具体方式 防止大横杆 2滑动， 比如说： 用紧固件将扣件 13的紧固部 131与门架横杆 12固定时， 就可以使扣箍条 132保持对大横杆 2相应的作用力； 也可以将 大横杆 2的适当部分设为与扣箍条 132相配合的结构， 等等。
本领域技术人员可以理解， 遮蔽件不限于槽钢 14, 用宽度适当的钢板 或角钢， 同样也能够拦截沙浆， 避免扣件 13粘连沙浆； 另外， 本例中， 槽 钢 14与门架横杆 12具有较大的跨度，槽钢 14还具有加强门架 1刚度的作 用。 可以理解， 也可以使门架 1上的遮蔽件与扣件 13保持较小的距离； 参 考图 6, 图 6是本发明提供的另一种门架的主视方向结构示意图； 槽钢 14 位于门架横杆 12上方， 槽钢 14完全罩住在同一个门架 1上的扣件 13 , 实 现上述目的； 同时， 为了保证门架 1具备适当的刚度， 还可以在门架 1下 部增加加强杆 16。
为了方便施工人员进行施工作业， 门式脚手架上还需要铺设适当的脚 手板。 参看图 7和图 8, 图 7是实施例提供的门式脚手架的外视方向结构 示意图， 图 8是实施例提供的门式脚手架的立体结构示意图。 门式脚手架 还包括多个小横杆 21和脚手板 22; 小横杆 21两端分别搭在大横杆 2上， 形成能够铺设脚手板 22的工作层， 小横杆 21之间具有适当的距离， 以为 上方的脚手板 22提供足够的支承力。 为了使脚手板 22铺设更加方便， 如 图 5所示的图 3中门架连接处的 A—— A剖视结构示意图， 工作层的上平 面的高度与所述槽钢的上平面的高度相等； 这样， 小横杆 21的上边与槽钢 14上平面在一个平面内， 在铺设脚手板 22时， 就可以非常容易地使脚手 板 22与小横杆和槽钢 14同时接触， 使每个小横杆 21都能为脚手板 21提 供支承力； 这样也可以保证施工时脚手板 22受力的均匀性。 当然， 在用其 他部件作为遮蔽件时， 也可以使其上边或面与小横杆 21 最高侧边保持平 齐， 以方便脚手板 22的铺设。 为了保证小横杆 21的稳定性， 可以用绑扎 带 7将小横杆 21与大横杆 2固定。优选的技术方案是用塑料绑扎带 7将小 横杆 21与大横杆 2固定， 与釆用扣件相比， 用塑料绑扎带的意义在于： 第 一、 塑料绑扎带具有重量轻， 携带方便的特点， 能够使脚手架部件的运输、 搭建与拆卸更加方便； 第二、 塑料绑扎带本身成本较低， 再加上釆用塑料 绑扎带具有循环利用率高的特点， 能够进一步地降低脚手架的成本。 可以 理解， 在特定情况下， 为了满足实际需要， 也可以用金属绑扎带， 也能够 使脚手架搭建、 拆卸更加方便。
可以理解： 也可以在小横杆 21 端部设适当的机构， 比如说： 如图 9 所示本发明提供的另一种小横杆的结构示意图，可以在小横杆 21端部设向 下伸出的挡杆 211 ; 也可以在大横杆 2上设适当的机构使小横杆 21固定， 同时保证小横杆 21拆卸的方便。
在需要在安装护栏时， 可以用绑扎带 7将合适的护拦杆 6绑在门架 1 的立杆 11上； 护拦杆 6与立杆 11的连接位置不受限于端部的连接机构， 因此， 可以根据实际施工的需要将护拦杆 6连接在合适的位置， 进一步减 小门式脚手架的成本； 同样可以釆用塑料绑扎带固定护拦杆 6, 也能够产 生上述的技术效果。
在建筑施工过程中， 在建筑物 100存在外凸结构时， 可以选择宽度不 同的门架 1相配合， 以使脚手架与施工作业面保持适当的距离。 请参考图 10, 图 10是本发明实施例提供的门式脚手架俯视方向结构示意图； 门架 1 进一步包括第一门架 103和第二门架 104, 第一门架 103的宽度小于第二 门架 104的宽度。建筑物 100的外凸结构与普通表面之间具有分界面 300, 分界面 300两侧分别用适当宽度的第一门架 103和第二门架 104搭建。 第 一门架 103和第二门架 104的门架横杆 12分别具有两个扣件 13 , 多个第 一门架 103内侧通过第一内大横杆 201连接在一起； 同样， 多个第二门架 104内侧通过第二内大横杆 202连接在一起；第一门架 103和第二门架 104 外侧通过外大横杆 200连接在一起。 第一内大横杆 201伸出第一门架 103 , 并向第二门架 104方向伸出，其伸出端与第二门架 104的门架横杆 12固定， 这样使第一门架 103和第二门架 104连接成一个整体。 本发明中， 第一内 大横杆 201与第二门架 104的连接位置可以根据分界面 200的位置确定， 不需要根据第一内大横杆 201长度确定。 因此， 可以根据需要使第一内大 横杆 201伸出适合长度，在合适的位置将第一内大横杆 201与第二门架 104 固定； 也不必准备多种长度的第一内大横杆 201 ; 因此， 减少了门式脚手 架零部件的库存量， 进而降低施工用料的管理难度， 降低门式脚手架的成 本； 另外， 由于第一内大横杆 201与第二门架 104连接位置可以根据实际 需要进行选择， 因此， 能够保证门式脚手架的工作层与施工作业面之间具 有合适的距离， 进而为施工作业提供便利。
本领域技术人员可以理解， 在建筑物 100具有多个外凸结构时， 可以 用更多种宽度不同的门架 1相结合搭建门式脚手架； 另外， 第一内大横杆 201可以通过绑扎带 7与第一门架 104的门架横杆 12固定， 也可以通过其 他方式固定， 比如说， 可以在第二门架 104的门架横杆 12设多个扣件 13 , 或设可拆卸的扣件 13 , 以适应建筑物 100不同的外凸结构的需要。 以上所述仅是本发明的优选实施方式， 应当指出， 对于本技术领域的 普通技术人员来说， 在不脱离本发明原理的前提下， 还可以做出若干改进 和润饰， 这些改进和润饰也应视为本发明的保护范围。
