Description
SP板装配式古城墙加固结构
技术领域
[0001] 本实用新型属于古建筑加固领域，特别是一种将SP板插放于型钢内作为古城墙的加固结构。
背景技术
[0002] 我国拥有五千年的历史和文化，同时也遗留了大量的城墙遗址。城墙经历岁月的侵蚀，不可避免的会坍塌损毁，在坍塌后能进行有效的修缮则成了古城墙加固技术中的重点。现有技术中，城墙采用的是内填素土夯实，外包青砖的加固方法。这种加固方法加固的城墙，一旦遇上连续的大雨，城墙内的土经雨水浸泡后便会膨胀，随着侧压力越来越大，外侧的青砖墙体一旦无法抵抗巨大的侧压力，城墙即出现垮塌，坍塌后内部的沙土就会全部涌出来。
[0003] 现有古城墙出现垮塌后，再进行修复也只是将填土重新夯实再外砌青砖，并无可靠地加固措施，一旦几天连续下雨，垮塌现象还会发生。许多著名旅游胜地的城墙经过修缮后，城墙的第二次倒塌通常为“雨水之祸”，例如平遥古城墙的二次坍塌，不仅造成巨大的经济损失还产生许多负面的社会影响。
实用新型内容
[0004] 本实用新型的目的是提供一种SP板装配式古城墙加固结构，解决古城墙内填土遇雨水膨胀后将外砌砖墙挤塌，无可靠加固措施的技术问题。
[0005] 为实现上述目的，本实用新型采用如下技术方案：
[0006] 一种SP板装配式古城墙加固结构，位于城墙土体底部的墙体基础之上，包括对称位于墙体基础两侧的独立基础，所述独立基础沿城墙土体的长度方向间隔设置，独立基础顶面通过预埋件固定有型钢架杆，所述型钢架杆贴合在城墙土体两侧的外表面上，型钢架杆的倾角与城墙土体的倾角一致，城墙土体两侧对称的型钢架杆之间由贯通城墙的横向拉杆连接，城墙土体同侧相邻的型钢架杆之间由水平拉杆连接，同侧相邻两型钢架杆的翼缘与腹板形成的槽内插放有SP预应力空心板，所述型钢架杆和SP预应力空心板的外侧砌筑有外墙。
[0007] 所述型钢架杆为H型钢或工字钢，标高低于城墙土体顶部200_。
[0008] 所述横向拉杆为H型钢，工字钢或槽钢，分层拉结在城墙两侧对称的型钢架杆下翼缘之间。
[0009] 所述水平拉杆为H型钢，工字钢或槽钢，分层拉结在同侧相邻的型钢架杆下翼缘之间。
[0010] 所述型钢架杆与横向拉杆及水平拉杆之间的连接为焊接或锚固。
[0011] 与现有技术相比本实用新型具有以下特点和有益效果：
[0012] 本实用新型克服了现有古城墙垮塌后，进行的修复只是将填土重新夯实再外砌青砖的方法，一旦几天连续下雨，垮塌现象还会发生，并无可靠加固措施的技术问题。[0013] 本实用新型的SP板装配式古城墙加固架能有效地抵抗土的侧压力，SP板本身具有较大的承载力，将它插放于型钢的槽内后形成挡土墙，城墙两侧型钢通过拉杆拉结一起来抵抗土的侧压力，外侧再用砂衆砌筑青砖将土巩固在墙内，结构安全可靠。
[0014] 本实用新型施工方法简单易行，费用低廉，省时省力。
附图说明
[0015] 下面结合附图对本实用新型做进一步详细的说明。
[0016] 图1是本实用新型的主视结构示意图。
[0017] 图2是图1中A-A剖面的结构示意图。
[0018] 图3是图1中B-B剖面的结构示意图。

具体实施方式
[0020] 实施例参见图1-2所示，一种SP板装配式古城墙加固结构，位于城墙土体I底部的墙体基础2之上，包括对称位于墙体基础2两侧的独立基础3，所述独立基础3沿城墙土体的长度方向间隔设置，独立基础3顶面通过预埋件9固定有型钢架杆4，所述型钢架杆4贴合在城墙土体两侧的外表面上，型钢架杆4的倾角与城墙土体I的倾角一致，城墙土体I两侧对称的型钢架杆4之间由贯通城墙的横向拉杆5连接，城墙土体I同侧相邻的型钢架杆4之间由水平拉杆6连接，同侧相邻两型钢架杆4的翼缘与腹板形成的槽内插放有SP预应力空心板7，所述型钢架杆4和SP预应力空心板7的外侧砌筑有外墙8。
[0021] 所述型钢架杆4为H型钢或工字钢，标高低于城墙土体顶部200_。所述横向拉杆5为H型钢，工字钢或槽钢，分层拉结在城墙两侧对称的型钢架杆下翼缘之间。所述水平拉杆6为H型钢，工字钢或槽钢，分层拉结在同侧相邻的型钢架杆下翼缘之间。所述型钢架杆4与横向拉杆5及水平拉杆6之间的连接为焊接或锚固。
[0022] 这种SP板装配式古城墙加固架的施工方法，步骤如下：
[0023] 步骤一：将倒塌的城墙砖清理到作业区外，作业区清理完毕后，沿城墙土体I长度方向在墙体基础2的两侧对称做一系列间隔的独立钢筋混凝土基础，独立基础3的顶面预埋钢板埋件；
[0024] 步骤二 ：对应独立基础的位置在城墙土体I上分层打水平通孔；
[0025] 步骤三：在独立基础的预埋钢板上连接型钢架杆4 ；
[0026] 步骤四：将横向拉杆5放入水平通孔内并连接城墙土体两侧的型钢架杆4 ；
[0027] 步骤五：同侧相邻的型钢架杆4之间分层连接水平拉杆6 ；
[0028] 步骤六：使用吊车将SP预应力空心板7插放在相邻两型钢架杆4的翼缘与腹板形成的槽内；
[0029] 步骤七：SP预应力空心板7与型钢架杆4接触缝隙用水泥砂浆灌实；
[0030] 步骤八：回填城墙坍塌部位的土体和水平贯通部位的土体，每填充500mm后，均应
夯实三遍；
[0031 ] 步骤九：进行城墙的外墙8砌筑，边砌筑边用水泥砂浆填充外墙8与SP预应力空心板7之间的空隙。
[0032] 本实用新型中使用的构件，均需要根据城墙的土质、厚度、高矮经计算决定，例如本实施例中，独立基础可沿城墙方向每隔9米设置一个，尺寸可设为800 X 800 X IOOOmm ;独立基础顶面预埋尺寸为700X 500X 20mm的钢板预埋件；型钢架杆4可使用350X350H型钢；如图3所示，横向拉杆5可使用两槽钢焊接而成，焊脚尺寸为5mm。横向拉杆5沿城墙土体高度方向可拉结5道，水平拉杆6可使用25#槽钢，由沿城墙土体拉结三道；SP预应力空心板7的尺寸可为厚度300mm，宽度1200mm，长度8950mm，并用吊车将SP板插放于H型钢的槽内。
[0033] 步骤二中，在独立基础的位置将城墙土体贯通时，宽度应保持在2000mm左右，注意对填土进行保护，防止坍塌伤人。
[0034] 本实用新型的所有型钢在安装前均应除锈，并涂刷两遍防锈漆，支架就位连接后再涂一遍防锈漆。
