Description
技术领域technical field
本实用新型涉及一种端部企口不出筋单向叠合板及支模结构,适用于叠合板和现浇梁的施工中。The utility model relates to a one-way laminated plate and a formwork structure with grooves and no ribs at the ends, which are suitable for the construction of laminated plates and cast-in-place beams.
背景技术Background technique
装配式混凝土建筑是指在主体结构部分或全部采用预制混凝土构件装配而成的钢筋混凝土结构建筑。为了保证装配式钢筋混凝土结构的整体受力性能与整浇结构等同,需要采取相应可靠的构造措施及施工方法,保证装配式结构中的预制部分、现浇部分、节点等能够协同工作,并确保其受力性能等于或者高于整浇结构。Prefabricated concrete buildings refer to reinforced concrete structures assembled with precast concrete components in part or all of the main structure. In order to ensure that the overall mechanical performance of the prefabricated reinforced concrete structure is equivalent to that of the cast-in-place structure, it is necessary to take corresponding reliable structural measures and construction methods to ensure that the prefabricated parts, cast-in-place parts, and nodes in the prefabricated structure can work together. Its mechanical performance is equal to or higher than that of the monolithic structure.
目前,梁柱使用现浇施工,板采用预制叠合板也是现今常用的施工方式之一,但是在楼板采用预制叠合板而混凝土梁为现浇的体系中,梁顶纵向钢筋与预制叠合板外伸“胡子筋”存在碰撞问题。如果梁钢筋先绑扎、叠合板后吊装时受到叠合板外伸“胡子筋”的影响,导致出现吊装过程中外伸“胡子筋”与梁纵向钢筋的“打架”问题。一方面大大延长了叠合板和现浇梁连接的作业时间,另一方面对叠合板吊装过程由于外伸胡子筋与梁纵筋碰撞,导致预制叠合板外伸“胡子筋”被弯折,导致预制混凝土板开裂的同时加大了工作量。反之,叠合板先安装,则必须先安装梁板模板为吊装提供操作空间、然后采用穿插的方式进行梁钢筋的绑扎,这种方式一方面也是耗时耗工,另一方面由于梁侧模板必须先安装,导致梁底纵筋与箍筋的绑扎很难到位,尤其是靠近柱子的梁端,两个方向的梁端钢筋在核心区相互穿插,无法采用传统的垫高提升的方式绑扎梁底纵筋与箍筋。At present, cast-in-place construction is used for beams and columns, and prefabricated laminated slabs are used for slabs. There is a collision issue with the Beard Rib. If the steel bars of the beams are bound first, and then the hoisting of the superimposed panels is affected by the outstretched "moustache bars" of the composite panels, the problem of "fighting" between the outstretched "moustache bars" and the longitudinal bars of the beams occurs during the hoisting process. On the one hand, the operation time of the connection between the laminated board and the cast-in-place beam is greatly prolonged. The cracking of the precast concrete slab increases the workload. On the contrary, if the laminated board is installed first, the beam-slab formwork must be installed first to provide operating space for hoisting, and then the beam and steel bars are bound by interspersed methods. On the one hand, this method is also time-consuming and labor-intensive. Install first, which makes it difficult to bind the longitudinal reinforcement and stirrup at the bottom of the beam, especially at the beam end near the column. The beam end reinforcement in the two directions is interspersed in the core area, and the traditional method of lifting the beam cannot be used to bind the bottom of the beam. Longitudinal bars and stirrups.
