The invention relates to a self-tapping screw block connecting structure of a longitudinal force transmission steel plate of an assembled one-shaped composite wallboard and a manufacturing method thereof, and belongs to the technical field of assembled concrete building engineering.
Background
Innovations and developments of efficient earthquake-resistant, green energy-saving fabricated structural systems suitable for village and town construction are the focus of engineering attention.
The technical development of the ultra-low energy consumption house is concerned by the engineering world at home and abroad. However, the construction technology of the low-energy-consumption multi-layer house in villages and towns, especially the assembly construction technology is quite deficient.
Technical bottleneck problems existing in the prior art are as follows: (1) The traditional precast shear wall adopts a cast-in-situ belt assembly mode, and the problems of long construction period, low assembly efficiency, difficult winter construction and the like are caused by larger cast-in-situ concrete amount. The traditional shear wall reinforcement structure has large distribution space and large reinforcement diameter, and if the reinforcement lap joint anchoring technology is adopted, the height dimension of the section of the post-cast strip is large, the cast-in-situ quantity is large, and the requirement that the height of the section of the post-cast concrete required by the assembly of the inner and outer single-row reinforced mesh concrete sheet sandwich polystyrene board wallboard is not suitable to be larger than 180mm is difficult to meet; (2) The traditional technology of connecting the reinforcing steel bars by the shear wall sleeve is not applicable to the assembly of the inner and outer She Shanpai reinforced mesh concrete thin plate sandwich polystyrene board wallboards at all, and the thickness of the inner and outer She Bao wallboards is only 40-60 mm; (3) The traditional technology of steel plate bolt connection of the shear wall is not suitable for the assembly of inner and outer She Shanpai reinforced mesh concrete thin plate sandwich polyphenyl plate wallboards, because the polyphenyl plates are clamped between the inner and outer leaf wallboards and the polyphenyl plates do not allow punching to penetrate bolts in consideration of the heat bridge problem, the inner and outer leaf concrete thin wall boards are difficult to be assembled respectively by adopting the traditional steel plate 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 inner and outer She Shan rows of reinforced net concrete thin plate sandwich polystyrene board wall boards belongs to the assembly of reinforced concrete wall boards, and simultaneously friction force and biting force are required, so that the current technology of directly connecting light steel keels by self-tapping nails is obviously difficult to meet the assembly of the inner and outer leaf concrete thin boards of the composite wall boards and the force transmission requirement of the inner and outer leaf concrete thin boards.
