Can a square floor bear 1 ton?
A square floor can't bear 1 ton, but only 0.8 ton at most. Because according to the relevant codes of building structure, the load of each square floor of general civil buildings needs to reach 0.2 tons, and only gymnasiums and dance halls can bear the limit of 0.8 tons, so 1 square floor cannot bear the weight of 1 ton. If you need to bear such a large weight under special circumstances, you can put a cushion under the item, and the area of the cushion is larger to spread the load on the floor.
The lowest cost scheme of floor reinforcement
1, CFRP reinforcement method
In this method, carbon fiber cloth is attached to the tensile part of the bottom of the plate along the span direction through structural adhesive for building, and it must be anchored reliably at its end. Its advantages are light weight, high strength and multi-layer bonding. After reinforcement, the weight of the original members is basically not increased, and the shape of the structure is not affected, which not only improves the bearing capacity of the structure, but also enhances the stiffness of the structure.
2, increase the section reinforcement method
This method is to add a layer of reinforced concrete post-pouring layer with a thickness of not less than 40mm on the surface or bottom of the plate. In order to facilitate construction, rigid floors and roofs are often formed by slab casting. If the laminated layer must be poured at the bottom of the board, the bottom of the board should be roughened and sprayed. The steel bar shall be hot rolled steel bar, and the diameter of the stressed steel bar of the plate shall not be less than 8 mm ..
3, paste steel plate method
This method is actually a compromise between the first and the second. The effect of steel plate is definitely not as good as thickening a layer of reinforced concrete, but the texture is definitely light. The effect of steel plate is stronger than that of carbon fiber cloth, but the flexibility is not high. Therefore, for this method, the following provisions shall be met:
(1) When the influence of secondary stress is considered, the lag strain effect of steel plate should be determined according to the initial stress of reinforcement in the member.
(2) Before reaching the ultimate state of flexural capacity, the bond peeling failure between the externally bonded steel plate and the concrete cannot occur.
(3) After reinforcement of reinforced concrete structural members, the increase of flexural capacity of normal section should not exceed 40%, and the shear capacity should be checked to avoid shear failure of members before flexural failure.
