[0002] The basement roof reinforcement structure is a series of measures taken to improve the bearing capacity and stability of the basement roof.

[0003] A search revealed a Chinese patent application with publication number CN206448358U, which discloses a reinforcement band structure between basement roof and floor slabs. The band structure comprises a reinforcement band, cast-in-place concrete layers on either side of the band, and a base plate below the band. The reinforcement band and the cast-in-place concrete layers are separated by a curved concrete retaining plate. This reinforcement band structure can better offset tensile stress from the cast-in-place concrete layer and reduce the use of expansion additives.

[0004] Based on the above search and combined with existing technology findings;

[0005] The structure of the above-mentioned searched patent is unstable, and the traditional connecting passages between different foundation pits are directly connected at the top plates of the connecting passages after the piles are removed, and there is no structural beam supporting the lower part. This part often has a large longitudinal span, and after the top plate is cast, this part often cracks and leaks, so there are certain limitations. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a top plate reinforcement structure for the connecting passage between foundation pits, which has better stress-bearing effect, is more solid and durable, and avoids cracking of the basement top plate due to temperature shrinkage, thereby improving economic benefits.

[0008] Preferably, steel bars are fixedly installed inside the inner and outer guard piles, wherein the ends of the steel bars in the inner guard piles are fixedly passed through the structural beams and are fixedly connected to the basement top slab, and the ends of the steel bars in the outer guard piles are fixedly connected to the bottom of the basement top slab.

[0009] Preferably, expansion joints are provided between the structural beams, and waterproof grease is applied inside the expansion joints.

[0010] Compared with the prior art, the present invention has the following significant advantages:

[0011] First, the present invention can significantly improve the stability of the entire structure by strengthening the top plate, effectively reduce structural damage, and withstand greater loads. The design and construction of the top plate reinforcement structure are relatively simple, which is conducive to improving construction efficiency.

[0012] Secondly, the top plate reinforcement structure of the utility model can better resist the influence of various external factors, the top plate reinforcement structure has good durability, extends the service life of the building, and the maintenance cost is relatively low.

[0013] The problem of connecting passages between existing different foundation pits has been solved. After the piles are removed, the top plates of the connecting passages are directly connected, and there is no structural beam supporting the lower part. This part often has a large longitudinal span, and after the top plate is poured, this part often cracks and leaks. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The utility model provides a roof reinforcement structure for connecting passages between foundation pits through improvement. The technical solution of the utility model is:

[0022] like Figure 1-Figure 3 As shown, a top plate reinforcement structure for connecting passages between foundation pits includes a pair of basement top plates 1, a negative first floor beam plate 2 and a negative second floor beam plate 3. Structural beams 5 are fixedly installed inside the pair of basement top plates 1. A pair of inner retaining piles 4 are fixedly installed between the pair of basement top plates 1 and the structural beams 5. A pair of outer retaining piles 41 are fixedly installed on both sides of the pair of basement top plates 1. The inner retaining piles 4 and the outer retaining piles 41 both pass through the negative first floor beam plate 2 and the negative second floor beam plate 3. The construction process of the retaining piles is simple, which improves the connectivity between the pile bodies and the stability of the overall structure.

[0023] Furthermore, steel bars 6 are fixedly installed inside the inner guard pile row 4 and the outer guard pile row 41, wherein the ends of the steel bars 6 located in the inner guard pile row 4 are fixedly passed through the structural beam 5 and are fixedly connected to the basement top plate 1, wherein the ends of the steel bars 6 located in the outer guard pile row 41 are fixedly connected to the bottom of the basement top plate 1. The provision of the structural beam 5 can make the basement top plate 1 bear better stress and be more stable and strong.

[0024] Furthermore, expansion joints 7 are provided between the structural beams 5, and waterproof grease 8 is applied to the interior of the expansion joints 7. By providing the expansion joints 7 and applying the waterproof grease 8, cracking and leakage of the floor slab can be effectively avoided, thereby improving safety and economy.
