With the popularization of national green energy-saving and environment-friendly policies, fabricated buildings emerge like bamboo shoots in spring after raining in China, and the fabricated buildings refer to buildings which are formed by transferring a large amount of field operation work in the traditional construction mode to factories, transporting well-processed and manufactured building components and accessories in the factories to building construction sites and assembling and installing the components and the accessories on the sites in a reliable connection mode.
Prefabricated exterior wall panels are widely used in residential construction as a typical prefabricated building. At present, the prefabricated external wall panel is integrally prefabricated by a light aggregate single material or a composite material, the lower wall of the window is a wall body of the part below the window in the width of the window, the structure of the prefabricated external wall panel is the same as that of the prefabricated external wall panel, the self weight and the rigidity after the prefabrication are large, and if the prefabricated external wall panel meets an earthquake or is subjected to wind load, stress concentration is easily caused to cause the damage of the lower wall of the window.
Disclosure of Invention
The utility model aims to solve the problem that prefabricated side fascia window lower wall damaged easily behind the great and atress of dead weight and rigidity, provide a prefabricated side fascia window lower wall structure, its simple structure can alleviate dead weight, reduce rigidity, has avoided the condition that the window lower wall takes place to damage under wind load and seismic action.
The technical scheme of the utility model is that:
the utility model provides a prefabricated external wall panel window is wall structure down, is including arranging the prefabricated outer page or leaf wall in the outside in, arranging the prefabricated interior page or leaf wall in the most inboard in, and its technical essential is: the prefabricated inner leaf wall is internally provided with anti-cracking structural steel bars which are bound into a quadrangular prism shape, the anti-cracking structural steel bars are hollow and filled with extruded polystyrene boards, and a heat insulation layer is arranged between the prefabricated inner leaf wall and the prefabricated outer leaf wall.
Foretell wall structure under prefabricated exterior wall panel window, the inboard bending type in prefabricated outer leaf wall top becomes the horizontally locating plate that shelters from, shelters from between locating plate and the prefabricated interior leaf wall and has still arranged the shutoff layer at the top that is located the heat preservation.
Foretell wall structure under prefabricated exterior wallboard window, the upper end of prefabricated outer page or leaf wall and the upper end parallel and level of prefabricated interior page or leaf wall, the height that prefabricated outer page or leaf wall highly is higher than prefabricated interior page or leaf wall, the lower extreme of prefabricated outer page or leaf wall is located the below ground.
Foretell wall structure under prefabricated external wall panel window, the thickness of both sides is 80mm around the prefabricated interior leaf wall.
The prefabricated external wall panel window lower wall structure is characterized in that the anti-cracking structural steel bars comprise four transverse steel bars arranged on the upper portion and the lower portion correspondingly, a plurality of annular steel bars wrapping the four transverse steel bars, a plurality of front and rear limiting steel bars arranged on the outer sides of the annular steel bars and tightly attached to the annular steel bars, and transverse limiting steel bars clamped between the limiting steel bars and the annular steel bars and bent into a hook shape.
The utility model has the advantages that:
1. the prefabricated outer leaf wall is reinforced concrete structure, and the locating plate that shelters from that sets up at the top had both been injectd the position of heat preservation, can fix the shutoff layer again, and prefabricated outer leaf wall lower extreme stretches into the below ground, has water-proof effects, makes overall structure firmer, and the shutoff effect is better.
2. The heat preservation layer is arranged, so that the structure has a good heat preservation effect.
3. The structural design of the internal anti-cracking structural steel bars of the prefabricated inner leaf wall effectively prevents the prefabricated inner leaf wall from cracking, the extruded polystyrene boards filled inside form a light wall body together with a reinforced concrete structure, and the light wall body, the heat insulation layer and the prefabricated outer leaf wall form a sandwich-shaped integral structure, so that the rigidity of the lower wall structure of a window of the prefabricated outer wall board can be weakened, the self weight is reduced, and the prefabricated outer wall board is prevented from being damaged under the action of wind load and earthquake.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a sectional view taken along line a-a of fig. 1.
In the figure: 1. the prefabricated outer leaf wall, 2 prefabricated inner leaf wall, 3 anti-cracking structural steel bars, 4 annular steel bars, 5 transverse limiting steel bars, 6 extruded polystyrene boards, 7 transverse steel bars, 8 front and rear limiting steel bars, 9 heat insulation layers, 10 shielding positioning plates and 11 blocking layers.
Detailed Description
