The utility model provides a suitable house number of piles is not higher than six layers in view of this embodiment, vertical load is not big, traditional block wall's bearing capacity has more than enough, and the reinforcing bar of the wallboard of assembled plate structure formula building configuration has improved the vertical bearing capacity of wall body again, event vertical enough safety of bearing, this embodiment has emphatically verified wall body safety (ductility) under the earthquake action, through the contrast test to the resilience characteristic (low week reciprocating load) of traditional brickwork bearing wall and assembled plate structure formula wall body promptly, verify the effect of this patent to improving wall body ductility through its fracture load, the fracture displacement, the damage load, the damage displacement.
The traditional wall body has no obvious sign of cracking, the horizontal bearing capacity enters a limit state quickly after cracking and is reduced quickly, obvious brittle failure characteristics are shown, and the crack is wide and sparse and is brittle failure; the horizontal bearing capacity of the wall body spliced by the embodiment is slowly reduced after the horizontal bearing capacity reaches the limit load, the reinforcing bars in the plate enter a working state, most of shearing force is shared, the stress distribution of the wall body is more uniform, and the phenomenon that a plurality of fine inclined cracks are generated near the main cracks is shown. Table 1 shows the results of the wall restoring force characteristic test.
Table 2 wall restoring force characteristic test results
As can be seen from the table: compared with the traditional wall and the assembled plate-structure-type wall body, the variable is whether the reinforcing bars are arranged in the plate wall or not. Compared with the cracking load of a non-rib test piece in the plate, the cracking load of the in-plate rib test piece is increased by 38.5%, the limit load is increased by 33.9%, and the anti-seismic bearing capacity of the assembled plate structure wall body with the in-plate ribs is obviously improved, so that the stress distribution of the wall body is more uniform, and the energy consumption capacity is higher.
The strength grade of the precast concrete member is C30, and the strength grade of the cast-in-place partial concrete is C25. In view of the limitation of strength grade of autoclaved aerated concrete, the building height of the embodiment is not higher than six layers of buildings, so that the buildings have enough safety, and the novel assembled plate structure integrated house which is built in an anti-seismic fortification area not higher than 9 degrees and is not higher than six layers is formed by taking autoclaved aerated concrete bearing wall plates (comprising outer wall plates and inner wall plates) which are designed and processed through special reinforcing bars as assembled wall bodies and matching concrete constructional columns, ring beams (the outer wall is a high ring beam), building (house) panels and the like. The large-size plates are assembled on site, a large amount of masonry mortar is saved, the labor intensity is reduced, the construction speed is improved, and the quality of all parts is reliably guaranteed because all parts are processed and manufactured according to the standard in the part processing part, so that the large-size plates are very suitable for being popularized and constructed in wide towns, villages and pastoral areas. The building, structural design and construction of the building system is different from masonry structures and concrete structures. The method is characterized in that the characteristics of light dead weight, excellent thermal performance, good crack resistance, strong durability, convenient construction and the like of the autoclaved aerated concrete plate are fully exerted, and the autoclaved aerated concrete plate is used as a vertical stress member to construct a building with less height-to-width ratio, more uniform rigidity distribution along the height, and less than six layers of walls mainly subjected to shear deformation under the action of horizontal load (the contribution rate of a first vibration mode reaches more than 80%), so that the building meets the category of determining the horizontal action of earthquake by using a bottom shear method specified in national standard building earthquake resistance design Specification GB 50011, thereby simplifying calculation, facilitating design and establishing brand new and complete assembly plate structure type building design principles and regulations different from traditional masonry structures and concrete structures. The development concept of building the new material assembled building is guided, the novel material → information processing → part processing → technical matching → field assembly → network sale is facilitated, and the development of the new material assembled building is promoted towards the scientific direction.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
