Description
Technical Field
The invention relates to a fabricated ecological inner wall and floor slab self-tapping nail cluster and post-cast strip combined connection structure and a fabrication method, and belongs to the technical field of fabricated concrete structures.
Background
The technical research and development of houses with ultra-low energy consumption always pay attention to the engineering industry at home and abroad. However, the construction technology, especially the assembly type construction technology, of the low-multi-layer ultralow-energy-consumption house in villages and small towns is quite deficient at present. There are technical bottlenecks:
ecological interior wall connection problem of upper and lower assembled: (1) the traditional technology of connecting the steel bars by the shear wall sleeves is not suitable for a combined ecological wallboard for installing the ecological wallboard in the reinforced concrete frame at all, because longitudinal force transmission steel bars which can be connected up and down are not arranged in the top beam and the bottom beam of the reinforced concrete frame; (2) the traditional steel plate bolt connection technology for the shear wall is not suitable for assembling an inner wall with an ecological wallboard arranged in a reinforced concrete frame, because the bolt connection node has high requirement on the assembly precision of the wallboard, generally not more than +/-1 mm, and the construction difficulty of hidden projects such as embedding a nut in the wall is high, the construction quality is difficult to guarantee; (3) the traditional shear wall shear screw connection technology is not suitable for assembling an inner wall for installing an ecological wallboard in a reinforced concrete frame, because the construction of the shear screws needs to form holes in the ecological wallboard on the upper part of a reinforced concrete frame bottom beam, the waterproof and sound insulation performance of the wallboard is influenced, and meanwhile, the out-of-plane anti-overturning capability of the shear screws arranged in a single row on a thin wallboard is poor. (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 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 inner wall panel of the ecological wall panel built in the reinforced concrete frame belongs to the assembly of the reinforced concrete wall panel, and simultaneously requires friction force and snap-in force, so that the technology of directly connecting the light steel keel by the current self-tapping screw is obviously different from the assembly of the reinforced concrete frame of the ecological inner wall panel and the force transmission requirement of the reinforced concrete frame of the ecological inner wall panel; (5) the traditional shear wall cast-in-place belt assembly is not suitable for the construction of the assembled ecological inner wall due to the fact that the cast-in-place amount of concrete is large, the cost is high, and the flexibility is poor.
Ecological interior wall and floor's connection problem: (1) the width of the top beam of the reinforced concrete frame is 120mm consistent with the thickness of the wall plate, the steel bar anchoring distance (25d is 100mm) is removed, the lap joint width of the floor slabs on two sides is 10mm respectively, and the stability of the floor slabs in the construction process is difficult to ensure; (2) the traditional fabricated concrete shear wall structure mostly adopts a steel bar truss floor bearing plate with a post-cast layer, and the cast-in-place amount is relatively large; (3) the connection structure of post-cast strip-shear screw rods is adopted at the connection node of the ecological inner wall and the floor slab, so that the problem of assembly of the upper wall board and the lower wall board cannot be solved well.
