Background
Building industrialization is a new mode of business, and along with the continuous development of real estate industry in society, the mode of building industrialization is gradually formed along with the change of building economy, and assembly type buildings are also becoming more and more popular. In the assembled structural design, the large building node sample occupies smaller proportion, but the large building node sample is easy to form abnormal prefabricated parts due to the diversification of the forms, so that great inconvenience is brought to production, transportation and construction, and the cost is increased. Therefore, on the premise of ensuring the structural safety and not affecting the use function, the components are simplified and reasonably configured as much as possible, so that the smoothness and the efficiency of the whole engineering implementation are greatly affected, and the method is also a key point of the assembly type design.
The floating windowsill node is a building mode which is largely adopted in Guangdong regions, is convenient for lighting and improving space sense, and is generally divided into a windowsill top plate and a windowsill bottom plate. As shown in fig. 1, in the conventional cast-in-place construction method, a floating sill bottom plate a11 of an upper floor, a floating sill lower wall a121 of an upper floor, a floating sill top plate a13 of a lower floor, a structural beam A2 and a floor slab A3 of the lower floor are cast together; and then installing a window A4 between the floating windowsill top plate A13 and the floating windowsill bottom plate A11 of the same floor, thus finishing the construction of the floating windowsill.
As shown in fig. 2, in the conventional fabricated building design, the construction method of the floating sill is as follows: the structural beam A2 and the lower floor slab A3 are both superposed components, namely the structural beam A2 consists of a structural beam prefabricated part A21 and a structural beam cast-in-situ part A22, the lower floor slab A3 consists of a floor slab prefabricated part A31 and a floor slab cast-in-situ part A32, the structural beam prefabricated part A21 and a floating windowsill top plate A13 of the lower floor are designed into one prefabricated component, a floating windowsill bottom plate A11 of the upper floor and a floating windowsill lower wall A121 of the upper floor are designed into one prefabricated component, and after the two prefabricated components are connected and positioned with the floor slab prefabricated part A31, concrete of the structural beam cast-in-situ part A22 and the floor slab cast-in-situ part A32 is cast together.
The construction method of the floating windowsill in the existing assembly type building design has the following defects:
first, because the prefabricated part a21 of the structural beam and the floating sill top plate a13 of the lower floor are designed as a prefabricated part, the prefabricated part a21 of the structural beam is a long part, and the floating sill top plate a13 is shorter and only occupies a part of the length of the prefabricated part a21 of the structural beam, the prefabricated part becomes a special-shaped prefabricated part with larger length, the difficulty and the cost are increased for production, transportation and hoisting, and the connection between the prefabricated part a21 of the structural beam and the floating sill top plate a13 of the lower floor is easy to break and damage in the transportation and hoisting process.
Second, since the two prefabricated members are separated, they are required to be positioned by one supporting structure, respectively, when construction is performed, and the prefabricated member composed of the upper sill bottom plate a11 and the upper sill lower wall a121 is positioned on the cast-in-place portion a22 of the structural beam, which is neither fixed nor constructed.
