Description
技术领域technical field
本发明属于建筑技术领域，具体涉及一种组装工具式桁架叠合板，此叠合板为免支撑叠合板。The invention belongs to the technical field of construction, and in particular relates to an assembly tool-type truss laminated board, which is a support-free laminated board.
背景技术Background technique
建筑领域经常使用的传统叠合板构件，能够减少施工过程中的湿作业步骤和施工模板，提高施工效率。传统叠合板的不足之处在于整体刚度低，抗弯性能差、易开裂、钢筋用量多、板底支撑设置较多。传统钢筋桁架叠合板结构，在吊装过程中产生较大挠度变形，甚至导致基板开裂。叠合层施工过程中，板底须设置大量支撑来提高叠合板整体竖向承载力，减小基板挠度、避免基板开裂。因此，传统叠合板在施工中，需要大量人力、物力的投入，造成综合建造成本偏高。The traditional laminated plate components often used in the construction field can reduce wet work steps and construction templates in the construction process and improve construction efficiency. The shortcomings of the traditional laminated board are that the overall stiffness is low, the bending resistance is poor, it is easy to crack, the amount of steel bars is large, and the bottom support is provided more. The traditional reinforced truss composite plate structure produces large deflection and deformation during the hoisting process, and even causes the base plate to crack. During the construction of the laminated layer, a large number of supports must be provided at the bottom of the plate to improve the overall vertical bearing capacity of the laminated plate, reduce the deflection of the substrate, and prevent the substrate from cracking. Therefore, the construction of traditional laminated panels requires a lot of manpower and material resources, resulting in high comprehensive construction costs.
现有的传统钢筋桁架叠合板由预先制作的钢筋桁架和钢筋混凝土底板组成，钢筋混凝土底板浇筑时将由上弦杆、腹杆和下弦杆组成的钢筋桁架的下弦杆埋入，形成整体受力叠合板构件。叠合板中的钢筋桁架在浇筑叠合层现浇混凝土时起到提供竖向刚度作用，可提高施工过程叠合板承载能力。腹杆连接上下弦杆形成空间稳定结构并兼具提高新旧混凝土结合面抗剪性能。在混凝土浇筑完成后，钢筋桁架全部埋入混凝土，造成楼板钢筋配置过渡冗余，形成钢筋“浪费”，造成叠合板构件综合制造成本增加。The existing traditional reinforced truss composite panel is composed of prefabricated reinforced truss and reinforced concrete bottom plate. When the reinforced concrete bottom plate is poured, the bottom chord of the reinforced truss composed of upper chord, web and lower chord is buried to form an overall stress-bearing composite panel. member. The reinforced trusses in the composite slab provide vertical stiffness when pouring the cast-in-place concrete of the composite layer, which can improve the bearing capacity of the composite slab during construction. The webs connect the upper and lower chords to form a spatially stable structure and simultaneously improve the shear resistance of the new and old concrete joint surfaces. After the concrete pouring is completed, the steel trusses are all buried in the concrete, resulting in a transitional redundancy in the configuration of the steel reinforcement on the floor, resulting in a "waste" of steel reinforcement, resulting in an increase in the comprehensive manufacturing cost of the composite panel components.

步骤十：拆卸桁架支撑梁Step 10: Remove the truss support beam
浇筑完上部混凝土后对混凝土表面收光处理，待混凝度达到一定强度后将桁架支撑梁拆除，拆除桁架支撑梁时首先将螺母拆除，拆除螺母后依次将桁架支撑梁及加长螺栓拆除。螺母、桁架支撑梁、加长螺栓拆除后再进行后续叠合板的使用。After the upper concrete is poured, the surface of the concrete is polished.
