Concrete and asphalt combined prefabricated pavement slab, steel formwork for pouring and prefabricating method
The invention discloses a concrete and asphalt combined prefabricated pavement slab, a steel formwork for pouring and a prefabricating method. The concrete and asphalt combined prefabricated pavement slab comprises a middle plate, a first side plate and a second side plate, each of the middle plate, the first side plate and the second side plate comprises a fine asphalt surface layer and a precast concrete plate; a plurality of groups of bulges which are arranged in a quincunx shape are arranged at the combined position of the precast concrete slab and the fine asphalt surface layer; the steel formwork is used for pouring a rectangular prefabricated pavement slab and is of a rectangular frame structure, and a plurality of cutting marks are arranged on a frame. During prefabrication, firstly, all the prefabricated concrete slabs are arranged well, the prefabricated concrete slabs are sealed through a steel formwork, and a cutting mark is slid to the position between every two prefabricated concrete slabs; then, after a layer of prime coat oil and a layer of tack coat oil are sprayed on the upper surface of the precast concrete slab, the fine asphalt mixture surface layer is paved; and after the temperature of the fine asphalt mixture surface layer is lower than 50 DEG C, cutting the fine asphalt mixture surface layer. The compaction degree of the bituminous pavement in the tramcar rail area is guaranteed, and the construction efficiency is improved.
本发明公开了混凝土和沥青结合预制路面板及浇筑用钢模板和预制方法，包括中板、第一侧板和第二侧板；中板、第一侧板和第二侧板均包括细沥青面层和预制混凝土板；预制混凝土板与所述细沥青面层结合的位置均设有多组呈梅花形布置的凸起；钢模板用于浇筑矩形的预制路面板，是呈矩形的框体结构，边框设有多个切割标志；预制时，先将所有预制混凝土板排好，采用钢模板封闭，并滑动切割标志至每两块所述预制混凝土板之间；然后，在预制混凝土板的上表面洒一层透层油和一层粘层油后，铺装所述细沥青混合料面层；在细沥青混合料面层的温度低于50℃后，切割所述细沥青混合料面层。本发明保证有轨电车轨行区沥青路面的压实度，并提高施工效率。
