[0024] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0025] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0026] With reference to Figures 1-2 , Figure 1 It is a reinforcing state structure schematic view of the utility model; Figure 2 It is another structure schematic view of the reinforcing state of the utility model. A large-span floor reinforcing structure comprises: a support assembly 1 and a tension assembly 2, the support assembly 1 is arranged at the bottom of the floor; and the tension assembly 2 comprises a first tension piece 21 and an anchoring piece 22, at least one first tension piece 21 is arranged on the side of the support assembly 1 away from the floor, and the support assembly 1 is supported, the anchoring piece 22 is connected with both ends of the first tension piece 21, and the anchoring piece 22 is arranged on the floor beam and fixes the first tension piece 21.

[0027] The large-span floor reinforcing structure, by setting the support assembly 1 for supporting the floor, and by the first tension piece 21 with both ends fixed on the floor beam by the anchoring piece 22 supporting the support assembly 1, upward counterforce is actively applied, a part of the floor load is balanced, and the purpose of reinforcing the floor is achieved, the reinforcing structure is simple in construction, short in construction period and low in cost, after the floor load is balanced by the reinforcing structure, the load increment of the floor transmitted to the floor beam is zero, the effect of simultaneously reinforcing the floor beam is achieved, and the problems of long construction period, large surface damage and much dust in the traditional steel adhering reinforcing method are avoided.

[0028] Specifically, the positions of the first tension piece 21 fixed on the floor beam through the anchoring piece 22 are slightly lower than the floor, and the first tension piece 21 is in a "V" shape when supporting the support assembly 1, so that the first tension piece 21 can apply force upward to the support assembly 1, and the support assembly 1 can apply upward counterforce to the floor, so that the purpose of reinforcing the floor is achieved.

[0029] The tensioning assembly 2 further comprises a turning piece 23 connected between the first tensioning piece 21 and the support assembly 1 and assisting the first tensioning piece 21 in turning.

[0030] With reference to Figure 3 , Figure 3 It is a structural schematic diagram of the utility model. The tensioning assembly 2 further comprises a second tensioning piece 24 arranged on the side of the first tensioning piece 21 away from the support assembly 1 and supporting the first tensioning piece 21, and the two ends of the second tensioning piece 24 are fixed on the floor beam through the anchor 22, so that the first tensioning piece 21 can be supported by the second tensioning piece 24, the supporting capacity of the tensioning assembly 2 on the support assembly 1 is further improved, and thus the load of the load-bearing floor can be dispersed by four floor beams, and the bearing pressure of a single floor beam is reduced.

[0031] Specifically, the floor beam for anchoring the first tensioning piece 21 and the second tensioning piece 24 should be reinforced if the bearing capacity is insufficient due to an increase in load.

[0032] The support assembly 1 is composed of a first support piece 11 and a second support piece 12, the first support piece 11 is arranged at the bottom of the floor, the second support piece 12 is arranged at the bottom of the floor, the second support piece 12 is perpendicular to the first support piece 11, and the turning piece 23 is connected to the side of the second support piece 12 away from the floor.

[0033] Specifically, the first support piece 11 is located at the middle of one side of the floor, and the second support piece 12 is arranged perpendicularly to the first support piece 11 and located at the middle of the perpendicular side, so that the first support piece 11 and the second support piece 12 can form a cross shape and divide the large-span floor into two-span floors.

[0034] With reference to Figure 4 , Figure 4 It is a sectional structural schematic diagram of the utility model. Further, the side of the turning piece 23 in contact with the first tensioning piece 21 is arc-shaped, so that the first tensioning piece 21 in the shape of a "V" can smoothly turn around the arc surface of the turning piece 23, and the situation that one or more parts of the first tensioning piece 21 are in contact with the turning piece 23 at an angle and bear a large force, affecting the service life of the first tensioning piece 21, is avoided.

[0035] Specifically, the turning piece 23 is welded integrally with the second support piece 12, so that the turning piece 23 cannot deviate and cannot play a role in turning the first tensioning piece 21, and the distance between the first tensioning piece 21 and the second support piece 12 is increased, the first tensioning piece 21 cannot support the second support piece 12 and the first support piece 11 and apply force upward, and the situation that the floor cannot be reinforced occurs.

[0036] The first support member 11 and the second support member 12 are both I-beams and H-beams, and the first support member 11 and the second support member 12 are welded together as a whole.

[0037] Specifically, both the first tension member 21 and the second tension member 24 are unbonded steel strands, specifically Uϕ15.2 low-relaxation unbonded steel strands with a strength of 1860 N / mm². There are two first tension members 21, symmetrically arranged on both sides of the second support member 12, and two second tension members 24, symmetrically arranged on both sides of the first support member 11. This allows the two first tension members 21 and the two second tension members 24 to form a "well" shape to support the support assembly 1, ensuring uniform force distribution when the tension assembly 2 supports the support assembly 1. This prevents uneven force distribution on the support assembly 1, which could affect the reinforcement effect of the floor slab, and also ensures a uniform service life for the tension assembly 2.

[0038] The first tension member 21 and the second tension member 24 are both fitted with flame-retardant PVC pipes, the support components 1 are all coated with anti-corrosion material, and the anchors 22 are wrapped with fine stone concrete. This ensures that the service life of the reinforced structure is basically synchronized with the original structure, avoids the need for multiple disassemblies and batch replacements when materials are replaced, and further reduces the construction period.

[0039] Anchor 22 is a round sleeve three-clamp single-hole anchor, and the anchor 22 is sealed to improve durability. The anchor 22 can be located on the side of the floor beam close to the support component 1 or away from the support component 1.
