Integrated cast-in-place construction method for diversion trench top plate
The invention relates to an integrated cast-in-place construction method for a diversion trench top plate, which comprises the following steps of: reversing the traditional construction process of the diversion trench top plate part, namely, firstly pouring a refractory concrete protective layer, then pouring top plate structure concrete, and using the poured refractory concrete of the diversion trench top plate as a template for pouring the top plate structure concrete. The connecting piece is introduced in the construction process, fire-resistant joint bar operation is carried out after top plate structural steel bar construction is completed, and the adverse effects of fire-resistant joint bars on construction operation and personnel safety are effectively reduced. Longitudinal bar penetrating holes and transverse bar penetrating holes are formed in one ends of the connecting pieces and used for being connected with a reinforcing mesh in the refractory concrete; and the other end is a threaded sleeve which is used for being connected with a fire-resistant joint bar. After the refractory concrete layer is poured for 24 hours, a roof structure reinforcing mesh is laid and bound, finally, refractory joint bars are installed, the refractory concrete protective layer and the structural concrete construction process are effectively fused, the formwork erecting frequency is reduced, and the overall construction efficiency is improved.
本发明涉及一种导流槽顶板一体化现浇施工方法，将导流槽顶板部位的传统施工工序进行颠倒，即先浇筑耐火混凝土防护层，随即再浇筑顶板结构混凝土，利用已浇筑完成的导流槽顶板耐火混凝土作为顶板结构混凝土浇筑时的模板。在施工中引入连接件，将耐火插筋作业放在顶板结构钢筋施工完成后进行，有效减少耐火插筋对施工操作和人员安全带来的不利影响。连接件一端设置纵筋穿孔和横筋穿孔，用来跟耐火混凝土内的钢筋网进行连接；另一端为螺纹套筒，用来跟耐火插筋进行连接。耐火混凝土层浇筑完成24h后，进行顶板结构钢筋网的布设和绑扎，最后安装耐火插筋，将耐火混凝土防护层和结构混凝土施工过程进行有效融合，减少支模次数，提高整体施工效率。
