Background
At present, the construction technology of the low-multilayer ultralow-energy-consumption house in villages and small towns, in particular to the construction technology of the assembled ultralow-energy-consumption low-multilayer house is very deficient. The technical bottlenecks existing in the prior art are as follows:
(1) in the traditional assembly type shear wall structure, adjacent prefabricated shear walls in floors are generally connected through integral seams, the constraint edge members and the construction edge members at the joints of the transverse walls or the longitudinal walls are constructed in a cast-in-place mode, the wet operation amount is large, the assembly rate is low, the construction speed is low, and the problems of large construction waste discharge amount and large noise in the construction process and environmental pollution are solved. (2) The traditional assembled shear wall structure is limited by the shapes and sizes of wall boards produced in a standardized manner, the flexibility of spatial arrangement is poor, and the traditional assembled shear wall structure cannot meet the requirements of buildings such as houses and offices with complex functional partitions. (3) The traditional steel plate bolt connection technology of the shear wall is not suitable for assembling the ecological inner wall with the reinforced concrete frame, because if the adjacent transverse walls or longitudinal transverse walls are assembled in a mode of connecting steel plates or angle steel by penetrating bolts, the sound insulation and waterproof capabilities of the wall body can be reduced; if the screw on bolt through interior wall frame post is connected to the adoption, the construction degree of difficulty is big, and the required precision is high, and need open the hole on ecological plate, influences that the wallboard is waterproof, give sound insulation, increases the fitment degree of difficulty. Therefore, the adjacent ecological inner walls on the same layer are difficult to be connected by adopting the traditional bolt connection technology; (4) the price of the self-tapping screw is much lower than that of the bolt, the thin-wall light steel keels of the thin-wall light steel keel structure are connected by the self-tapping screw, the self-tapping screw penetrates through the two connected light steel keels in sequence, force transmission between the light steel keels is realized through meshing with the self-tapping screw, and no extrusion friction force exists; however, the assembly of the assembled cross-shaped column and the ecological inner wall belongs to the assembly of a reinforced concrete wallboard and a constructional column, the connecting interface of the two mainly bears shearing force, and simultaneously needs friction force and snap-in force, and the current technology that a self-tapping nail is directly connected with a light steel keel is obviously different from the assembly of an inner leaf concrete thin wallboard and an outer leaf concrete thin wallboard of a composite wallboard and the force transmission requirements of the inner leaf concrete thin wallboard and the outer leaf concrete thin wallboard; (5) the cast-in-place area of traditional shear force wall is assembled, because the cast-in-place volume of concrete is great, the concrete mold expansion power is great, need add interim construction support and fix a position the template, the expense is higher and the flexibility ratio is relatively poor, is not suitable for the construction of ecological interior wall. (6) The wallboard is filled in the prefabrication of tradition assembled shear wall structure needs to reserve the assembly seam with adjacent wallboard or structure post, and there are sound insulation performance and waterproof performance subalternation problem in assembly seam department.
