传统的外墙保温施工方法有穿墙螺钉和木方格。绝缘板上开穿墙螺丝孔，容易损坏铝卷，后期需要堵塞，大大增加了施工成本；加固施工是通过螺钉、木方格和背面波纹的组合进行的。施工过程繁琐。在墙体中间放置一根水泥支撑杆，以保证墙体的横截面尺寸。熟练度调整，施工难度越大，质量越难保证。
The traditional construction methods of exterior wall insulation include through wall screws and wood checkers. The through wall screw holes are opened on the insulating plate, which is easy to damage the aluminum coil and need to be blocked later, which greatly increases the construction cost; The reinforcement construction is carried out through the combination of screws, wood squares and back corrugations. The construction process is tedious. A cement support rod is placed in the middle of the wall to ensure the cross-sectional dimension of the wall. The more difficult the construction is, the more difficult it is to ensure the quality.
在冬季，外墙保温装置一般包括外墙模板、外墙模板一侧的保温板和多个紧固装置。外墙模板包括一模板主体，模板主体平行于保温板，并从模板主体向远离保温板的方向延伸，多个侧面板。但外墙保温板在使用中存在缺陷。一是保温板之间的连接不紧密，二是外保温板不易更换。为了解决这个问题，现在采用铝卷和外墙保温板相结合的保温方法。
In winter, the external wall insulation device generally includes the external wall formwork, the insulation board on one side of the external wall formwork and multiple fastening devices. The external wall formwork comprises a formwork main body, which is parallel to the insulation board and extends from the formwork main body to the direction away from the insulation board, and a plurality of side panels. However, there are defects in the use of external wall insulation board. Firstly, the connection between insulation boards is not tight, and secondly, the external insulation board is not easy to replace. In order to solve this problem, the insulation method of combining aluminum coil and external wall insulation board is adopted.
铝卷与外墙保温板组合的施工结构主要包括保温板、钢筋混凝土现浇结构、铝模内墙板、方管夹具、方管背面、一次性拉片。钢筋混凝土现浇结构的内侧和外侧分别设有铝模内墙板和保温板，保温板外侧还设有固定保温板的钢架。
The construction structure of the combination of aluminum coil and external wall insulation board mainly includes insulation board, reinforced concrete cast-in-place structure, aluminum mold inner wall board, square tube clamp, square tube back, and one-time pull sheet. The inner side and outer side of the reinforced concrete cast-in-place structure are respectively provided with aluminum formwork inner wall plate and insulation board, and the outer side of the insulation board is also provided with a steel frame for fixing the insulation board.

将板材固定在钢架上，一次性拉片的两端与方管夹连接，使方管夹相互拉动时，铝卷与铝模内壁面板锁定在钢筋混凝土现浇结构的两侧。铝模内墙板上方设有垂直楼板模板，楼板模板与铝模内墙板通过楼板角槽连接；铝模内墙板的底部也铰接有墙板撑杆，墙板撑杆的另一端固定在地面上；保温板的高度超过其所在楼层的高度50mm。
Fix the plate on the steel frame, and connect the two ends of the disposable pull sheet with the square pipe clamp, so that when the square pipe clamp is pulled mutually, the aluminum coil and the inner wall panel of the aluminum mold are locked on both sides of the reinforced concrete cast-in-place structure. A vertical floor formwork is set above the inner wall panel of the aluminum mold, and the floor formwork is connected with the inner wall panel of the aluminum mold through the floor corner groove; The bottom of the inner wall panel of the aluminum mold is also hinged with a wall panel brace, and the other end of the wall panel brace is fixed on the ground; The height of the insulation board shall be 50mm higher than the height of the floor where it is located.
铝卷生产厂家认为双拉结构可以实现铝卷的锁紧，安装更方便，对工人施工经验的依赖很低。一次性双拉片根据壁厚定制，不需要水泥支撑条，减少了工艺和成本。施工完成后，上下敲击即可拆除，不留大孔，无需后期封堵作业。
The aluminum coil manufacturer believes that the double pull structure can realize the locking of aluminum coil, which is more convenient for installation and has low dependence on the construction experience of workers. The disposable double pull tab is customized according to the wall thickness, and no cement support strip is required, which reduces the process and cost. After the construction is completed, it can be removed by knocking up and down without leaving large holes, and there is no need for later plugging operation.
