Reinforcement Diagram for Prefabricated Slabs in Rural Houses

The following methods can be referred to for reinforcing prefabricated slabs in rural houses:

Using I-beams as crossbeams: Select I-beams of appropriate profiles according to the actual situation of the house. If the material size is small, the placement density can be higher; if the material size is large, the placement can be relatively sparse. Taking 20-sized steel as an example, place three I-beams in a cross shape with the prefabricated slabs. Erect I-beam columns at both ends for support, and firmly fix the columns to the walls. In many rural areas, the length of prefabricated slabs is 4 meters, and the distance between the two walls of a room is about 3.75 meters. After adding steel as a crossbeam in the middle, the distance on both sides is less than 2 meters, which can effectively enhance the hardness of the prefabricated slabs.

Adding a layer of concrete on the prefabricated slabs: First, knock out one of the middle prefabricated slabs, make a crossbeam, add a vertical beam on the crossbeam to form a cross-beam structure, and then add a floor slab on top to increase the thickness of the floor slab. Reinforce the floor slab in the form of a cross-beam to make the beam and the floor slab form a whole. However, under this reinforcement method, the walls still need further reinforcement. Because many old houses originally had brick wall structures without columns, and the walls have aged after long-term use, so columns are needed to reduce the pressure of the floor slab on the walls.

Pouring a reinforced concrete 'composite layer' on the prefabricated slabs: First, thoroughly clean the floating dust on the surface of the prefabricated slabs to ensure a clean and tidy surface. Then, lay a steel bar mesh with a diameter of 6 millimeters, and it is advisable to have a spacing of 20 centimeters square for the steel bar mesh. Finally, pour fine aggregate concrete with a grade not lower than C25, and the thickness is usually controlled between 5 and 8 centimeters. This method can effectively improve the overall rigidity of the roof and enhance the stability of the house.

Adding I-beams perpendicular to the direction of the prefabricated slabs: One way is to use a vertical I-beam at each end of the horizontal I-beam for support; another way is to install four I-beams connected end-to-end along the internal corners of the ceiling, and at the same time, erect a column at each of the four indoor corners to support the I-beams, thereby enhancing the load-bearing capacity of the prefabricated slabs.
