在工业厂房屋面施工中,大型屋面板的板缝灌细石混凝土时,多采用板底吊模板或板缝塞木条的作法。这种作法需要用大量的木料,特别是板底吊模板的作法,拆除时费人工也较多。为了节约木料,我们采取了以下两种作法:1.屋面板缝在1～3厘米时(指板缝底部宽度),可使用φ16～φ25钢筋弯成图1那种工具,放在板缝底部。自板缝一端开始,随灌捣混凝土随向前抽(在板底起一个滑模作用,见图2),到板另一端时,将工具向上斜向抽出,即完成一道板缝的灌细石混凝
In the construction of the surface of an industrial factory, when the concrete slabs of large-sized roof panels are seam-welded with fine stone concrete, the practice of slab-bottomed concrete slabs or wooden slabs with slab joints is often used. This practice requires the use of a large amount of wood, especially the practice of lifting slabs at the bottom of the slab. There are also more labor costs for demolition. In order to save wood, we have adopted the following two methods: 1. When the roof panels are stitched to 1 to 3 cm (refer to the width of the bottom of the panel seams), you can use φ16 to φ25 rebar to bend the tools shown in Figure 1 and place them on the bottom of the seams. . Starting from one end of the board slot, with the concrete pumping forward with the pumping (in the bottom of the board from a sliding mode, see Figure 2), to the other end of the board, the tool will be pulled out diagonally, that is, complete the filling of a board seam Stone coagulation
