Description
Technical Field
The invention relates to a block connection structure of an assembled T-shaped column and an ecological inner wall self-tapping screw and a construction method thereof, 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 existing in the prior art are that
(1) In the traditional assembly type shear wall structure, the adjacent shear walls in the floors are generally connected by adopting integral joints, and the constraint edge components and the structural edge components at the joints of the longitudinal walls or the transverse walls are all constructed by adopting cast-in-situ. (2) The traditional fabricated shear wall structure is limited by the shape and size of the wall plate produced in a standardized way, the flexibility of space arrangement is poor, the assembly difficulty is high, and the buildings such as houses and offices with complex functional areas are difficult to meet. (3) The traditional shear wall steel plate bolt connection technology is not suitable for the assembly of the ecological inner wall with the reinforced concrete sash, because if the adjacent transverse wall or the longitudinal transverse wall is assembled by adopting a mode of oppositely penetrating bolt connection steel plates or angle steel, the sound insulation and waterproof capability of the wall can be reduced; if the screw holes on the through bolts through the inner wall frame columns are adopted for connection, the construction difficulty is high, the precision requirement is high, holes are formed in ecological plates, the water resistance and sound insulation of the wallboard are affected, and the decoration difficulty is increased. Therefore, the adjacent ecological inner walls on the same layer are difficult to connect by adopting the traditional bolt connection technology; (4) 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 ecological inner wall and the T-shaped column of the assembled reinforced concrete frame lattice belongs to the assembly of the frame column and the constructional column of the ecological wallboard, and the connecting interface of the two 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 T-shaped constructional column and the frame column of the ecological wallboard and the force transmission requirement of the T-shaped constructional column; (5) 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.
