[0002] A cross-river building is a building built on a river. Cross-river buildings can reduce the occupation of urban land. For a city with a river, it is an ideal building method to save land and make full use of space. Moreover, cross-river buildings connect both banks of the river and play the role of a bridge.

[0003] Currently, cross-river buildings usually include a supporting bridge and a building for daily activities. The supporting bridge is built on the riverbed and the bank of the river, and the building for daily activities is located on the supporting bridge. There is a space for ships to navigate under the supporting bridge, and the bridge deck of the supporting bridge connects both banks of the river. However, since such cross-river buildings need to build a supporting bridge, columns usually need to be set in the middle of the river. The construction of columns requires cutting off the river or caisson construction, resulting in high construction difficulty and long construction period.

[0029] The present utility model proposes a cross - river building structure.

[0030] Please refer to Figures 1 to 2 , the cross-river building structure includes a first building part, and the first building part includes a first building main body 1, a cross-river building main body 2 and a second building main body 3. The first building main body 1 is constructed on one bank of the river 4, and the second building main body 3 is constructed on the other bank of the river 4. One end of the first building main body 1 facing the second building main body 3 is connected to one end of the cross-river building main body 2, and one end of the second building main body 3 facing the first building main body 1 is connected to the other end of the cross-river building main body 2 to support the cross-river building main body 2 spanning across the river 4 between the two ends.

Specifically, the support skeleton of the cross-river building main body 2 is a cross-river steel truss 21. Multiple rooms are respectively arranged on the first level and the second level of the first building main body 1 and on the first level, the second level and the third level of the second building main body 3. In this embodiment, the second level of the first building main body 1 is communicated with one end of the cross-river passage facing the first building main body 1, the second level of the second building main body 3 is communicated with one end of the cross-river passage facing the second building main body 3, and the second level of the first building main body 1, the cross-river passage and the second level of the second building main body 3 are connected as the same level.

[0031] In the technical solution of the present utility model, by constructing the first building main body 1, the cross-river building main body 2 and the second building main body 3, the cross-river building main body 2 is supported to span across the river 4 between the two ends of the first building main body 1 and the second building main body 3; since there is no need to build a support bridge, there is no need to set columns in the middle of the river 4, which reduces the construction difficulty and shortens the construction period. In addition, since the first building part is a steel structure building, the steel components therein are lighter than the reinforced concrete components, which reduces the construction difficulty. In addition, the steel components can be fabricated in the factory and installed on site, further shortening the construction period.

[0032] Preferably, the first building part includes a steel roof truss, a floor slab, an exterior wall, and a roof panel. The foundation of the first building part includes a plurality of bearing platforms, and each bearing platform is provided with at least one support column. The lower ends of the support columns are connected to the corresponding bearing platforms, and the upper ends of the support columns are respectively connected to the bottom end of the steel roof truss to support the first building part. The floor slab is used to be laid between the bottom end and the top end of the steel roof truss to layer the first building part. The exterior wall is used to be constructed around the steel roof truss to form the internal space of the first building part. The roof panel is used to be laid on the top of the steel roof truss. Laying and fixing the floor slab, the exterior wall, and the roof panel on the steel roof truss, and using the steel roof truss as the support framework to support the floor slab, the exterior wall, and the roof panel, a complete building structure can be formed; in this embodiment, the steel roof truss includes steel columns and steel beams, and the foundation form of the first building part is a pile foundation.

[0034] Preferably, the cross-river building structure further includes a branch building part. The foundation of the branch building part is a natural foundation, and the branch building part uses the backfill soil as the bearing stratum. The foundation of the first building part is an artificial foundation, and the foundation of the first building part uses the limestone stratum as the bearing stratum. In this embodiment, the branch building part is a single-story building, and the branch building part is disconnected from the first building part. Since the branch building part is light in weight, a natural foundation can be used, which can speed up the construction period.

[0035] Preferably, the cross-river building structure further includes multiple groups of connecting components. Each group of connecting components is arranged corresponding to the bearing platforms of the branch building part. Each group of connecting components includes a plurality of connecting elements. The upper end of the connecting element is connected to the corresponding bearing platform of the branch building, and the lower end of the connecting element is connected to the limestone stratum. Since the foundation of the branch building part uses the backfill soil layer as the bearing stratum, and the backfill soil layer contains organic matter and thus has expansibility, the expansion of the backfill soil layer will cause the foundation of the branch building part to be unstable. By setting the connecting components to connect the foundation of the branch building part to the limestone stratum, the influence brought by the expansion of the backfill soil layer can be resisted, making the foundation of the branch building part more stable.

[0036] Preferably, the connecting element comprises an anti-expansion anchor rod, the upper section of which is fixed in the cap of the corresponding branch building part, the lower section of which is fixed in the limestone layer, and the middle section of which is passed through the stratum between the cap and the limestone layer.

[0037] Preferably, the river-crossing building structure further comprises a cement connection structure, the upper end of which is connected to the bottom surface of the corresponding branch building's pedestal, the lower end of which is fixed to the limestone layer, and the cement connection structure is coated on the middle and lower sections of the expansion anchor rod. The cement connection structure is provided to resist the influence of the expansion of the backfill soil layer together with the anti-expansion anchor rod, and at the same time, the anti-expansion anchor rod is isolated from the outside world to prevent the anti-expansion anchor rod from rusting.

[0038] Preferably, the river-crossing building structure also includes a second building part, the first building part is arranged across the river 4, the second building part is constructed along the length direction of the river 4 on one bank of the river 4 where the second building body 3 is arranged, and one end of the second building part facing the first building part is connected to one end of the second building body 3.

Due to the building size and use function, it is not suitable to set deformation joints. The following measures are taken to reduce the adverse effects of shrinkage stress and temperature stress: post-cast strips are set every 40 meters or so, and the concrete is poured and connected together after most of the shrinkage is completed; the floor slab adopts full-length reinforcement; temperature stress calculation is performed, and reliable anti-cracking measures are taken according to the calculation results, such as strengthening the plate reinforcement; the floor slab and roof panel adopt shrinkage compensating concrete mixed with high-performance anti-cracking expansion agent; during construction, a special construction plan is adopted for large-volume concrete to reduce hydration heat, strengthen construction maintenance, and ensure construction quality.
