Embodiment Construction
[0046] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0047] refer to figure 1 , is the construction method that a kind of former prefabricated plate transformed into cast-in-place plate disclosed by the present invention comprises the following steps:
[0048] S1, material preparation;
[0049] combine figure 1 and figure 2 , prepare steel bar, transfer seat 3 and support rod 4.
[0050] A section of I-shaped steel with the same length and width is selected as the transmission seat 3 . The transfer seat 3 includes an upper flange 31 , a lower flange 32 and a web 33 . The upper flange 31 and the lower flange 32 are arranged parallel to each other and have the same size. One end of the web 33 is vertically connected to the middle of the upper flange 31 , and the other end of the web 33 is vertically connected to the middle of the lower flange 32 .
[0051] Through holes (not shown in the figure) are opene...

The invention relates to a construction method for transforming an original prefabricated slab into a cast-in-place slab. The construction method comprises the following steps: S1, materials are prepared; S2, stress is released, specifically, a transmission seat and a supporting rod are supported on the lower surface of the original prefabricated floor slab; S3, a pouring opening is formed, specifically, the penetrating pouring opening is formed in the original prefabricated floor slab; S4, edge supporting construction is conducted, specifically, a hole is formed in a wall and connected with the upper surface of the original prefabricated floor slab, and the hole is filled with plain concrete to form a plugging block; S5, a forced rib skeleton is formed by binding, specifically, steel bars are bound on the lower part of the original prefabricated floor slab to form the forced rib skeleton; S6, a formwork is erected, specifically, a horizontal bottom formwork is erected on the lower part of the forced rib skeleton, the bottom formwork corresponds to the middle of the transmission seat, and a steel pipe is supported on the lower part of the bottom formwork; and S7, concrete is poured, specifically, the concrete is poured on the position between the formwork and the original prefabricated floor slab through the pouring opening, and a reinforcement floor slab is formed after the concrete is solidified. The construction method has the effect of improving the structural strength of the original prefabricated floor slab.
Description
technical field [0001] The invention relates to the technical field of building structure reinforcement, in particular to a construction method for transforming an original prefabricated board into a cast-in-place board. Background technique [0002] During the development of the construction industry, some old-fashioned buildings retain the structure of prefabricated floor slabs. Due to the age of service and the change of some functions, prefabricated floors cannot meet the normal use of these buildings. [0003] It is necessary to provide a reinforcement construction method for the original prefabricated floor slab, so that the structural strength of the original prefabricated floor slab can be improved. Contents of the invention [0004] The purpose of the present invention is to provide a construction method for transforming original prefabricated slabs into cast-in-place slabs, which achieves the effect of enhancing the structural strength of the original prefabrica...
