Description
Technical Field
The invention relates to a T-shaped constructional column and ecological interior wall self-tapping screw block connection structure of an assembled composite wallboard and a construction method, and belongs to the technical field of assembled concrete building structure engineering.
Background
At present, the construction technology of the village and town low-multilayer ultralow-energy-consumption house, in particular to the construction technology of the assembled ultralow-energy-consumption low-multilayer house, which is quite deficient.
The technical bottlenecks of the prior art are as follows:
(1) In the traditional assembly type shear wall structure, the adjacent shear walls in the floors are generally connected by adopting integral joints, and constraint edge components and construction edge components at the joint of the longitudinal and transverse walls are cast-in-situ, so that the assembly mode has the advantages of large wet workload, low assembly rate, low construction speed, inflexible arrangement of building walls, large discharge of building rubbish and large noise in the construction process. (2) The traditional technology for connecting the steel plates of the shear wall by bolts is not suitable for assembling the inner and outer She Shanpai reinforced mesh concrete thin plate sandwich polystyrene plate composite wall plates and the ecological inner wall with reinforced concrete frame lattice, because the polystyrene plate is clamped between the inner and outer leaf wall plates and the polystyrene plate is not allowed to be perforated by bolts in consideration of the heat bridge problem. Meanwhile, if the composite external wall board and the ecological internal wall board are assembled and connected in a mode of oppositely penetrating bolt connecting steel plates or angle steel, the sound insulation and waterproof capacity of the wall body can be reduced, the construction difficulty is high, and the precision requirement is high. Therefore, the same-layer adjacent composite external wall boards and ecological internal walls are difficult to assemble and connect by adopting the traditional steel plate bolt connection technology; (3) The price of the self-tapping screw is much lower than that of a bolt, the thin-wall light steel keels of the thin-wall light steel keel structure are connected by adopting the self-tapping screw, the self-tapping screw penetrates through the two light steel keels connected in sequence, and force transmission between the light steel keels is realized through engagement with the self-tapping screw, so that the extrusion friction force is avoided; however, the assembly of the assembled composite external wall panel and the ecological internal wall panel belongs to the assembly of the composite wall panel constructional column and the ecological internal wall frame column, and the connecting interface of the assembled composite external wall panel and the ecological internal wall frame column mainly bears shearing force and simultaneously needs friction force and biting force, so that the existing technology of directly connecting the light steel joist by the self-tapping screw is obviously different from the assembly of the composite wall panel constructional column and the ecological internal wall frame column and the force transmission requirement of the composite wall panel constructional column and the ecological internal wall frame column; (4) The traditional shear wall cast-in-situ belt assembly is not suitable for the construction of an ecological inner wall due to the fact that the cast-in-situ amount of concrete is large, the expansion force of the concrete is large, a temporary construction support is needed to be additionally arranged to position a template, the cost is high, the flexibility is poor, and the construction method is not suitable for the construction of the ecological inner wall. (5) The prefabricated intussuseption of traditional assembled shear force wall structure fills wallboard, needs to reserve the assembly seam with adjacent wallboard or constructional column, and there is the poor scheduling problem of sound insulation performance and waterproof performance in assembly seam department.
