TECHNICAL FIELD
[0001] The utility model relates to the technical field of building construction reconstruction, especially the technical field of sunken square reconstruction, and specifically relates to a sunken square reconstruction structure. BACKGROUND
[0002] Building construction reconstruction refers to repairing, reconstructing or expanding existing buildings to adapt to new demands and functions. In the field of construction, construction reconstruction is a very important link, which is related to the performance, safety and overall image of the building.
[0003] For example, urban renewal reconstruction of commercial buildings increases sunken squares, aiming to improve the consumer experience, create a unique space atmosphere and provide a quiet shopping environment, and enrich the urban landscape system, so as to attract more consumers and promote the prosperity of commercial activities. The design of the sunken square aims to create a safe and secret enclosed feeling, and through the design of the enclosed space, a relatively independent and quiet shopping environment is provided for consumers, so as to achieve the psychological effect of relieving pressure. This design not only enhances the secrecy and quietness of the space, but also enriches the shopping experience to a certain extent, so that consumers can enjoy the pleasure of shopping in a relatively quiet environment, and are no longer limited to the noisy crowd, but can enjoy the quiet and leisurely strolling experience.
[0004] However, the technical problems of urban renewal reconstruction of commercial buildings to increase sunken squares mainly include:
[0005] (1) The position of the reconstruction and increase of the sunken square is the basement, and the roof, beams and columns of the first underground layer need to be removed, the first problem to be solved is drainage, there is no height difference between the indoor and outdoor of the sunken square, the underground drainage pipe of the second underground layer has been completed, the most direct method is to add a drainage pipe below the floor of the first underground layer (i.e. the roof of the second underground layer), to reconstruct and increase the drainage pipe of the second underground layer, which has a large amount of work;
[0006] (2) The sunken square considers greening and planting for landscape, and the load is also large, the bearing capacity of the floor slab (i.e. the beams and roof of the second underground layer) does not meet the requirements after calculation, the traditional column sticking method for reinforcing the columns of the second underground layer also cannot meet the reinforcement requirements, and the beam section of the second underground layer needs to be increased for reinforcement, the biggest problem of the method of increasing the beam section is that the existing pipelines at the bottom of the roof of the second underground layer need to be removed, and the corresponding drainage pipelines need to be supplemented, which has a large amount of work, a long construction period and high cost;
[0007] (3) In addition, after the first underground layer is removed, the anti-floating capacity of the region is insufficient, just like two boats connected together, when the bearing weight is consistent, the height of the boat floating on the water is consistent, and the structure above can remain stable, and at least 50cm thick soil needs to be added to increase the anti-floating load.

[0029] Please see Figures 3-4 As shown, in a specific embodiment of this utility model, the sunken plaza renovation structure of this utility model includes a left top floor slab 1 of the second basement level, a right top floor slab 2 of the second basement level, a beam 3 of the second basement level, a composite beam slab 4, and a drainage ditch 5, wherein:
[0030] The top left floor slab 1 and the top right floor slab 2 of the second basement level are both horizontally arranged and spaced apart from each other. The beam 3 of the second basement level is vertically arranged and arranged in the front-to-back direction. The beam 3 of the second basement level is located between the top left floor slab 1 and the top right floor slab 2 of the second basement level and connects the top left floor slab 1 and the top right floor slab 2 of the second basement level respectively. The top surfaces of the beam 3, the top surfaces of the top left floor slab 1 and the top surfaces of the top right floor slab 2 of the second basement level are flush.
[0031] The composite beam slab 4 is horizontally arranged and is respectively arranged on the top surface of the second basement floor beam 3, the top surface of the left top floor slab 1 of the second basement floor, and the top surface of the right top floor slab 2 of the second basement floor. The drainage ditch 5 is horizontally arranged in the top surface of the composite beam slab 4.
[0032] The composite beam slab 4 can be a plate made of any suitable material. In a specific embodiment of this utility model, the composite beam slab 4 is a concrete slab.
[0033] The thickness of the composite beam plate 4 can be determined as needed. In a specific embodiment of this utility model, the thickness of the composite beam plate 4 is 30cm.
[0034] The drainage ditch 5 can be installed in any suitable direction; please refer to [link / reference]. Figure 3 As shown, in a specific embodiment of this utility model, the drainage ditch 5 is arranged in the left-right direction.
[0035] The number of drainage ditches 5 can be determined as needed; please refer to [link / reference]. Figure 3As shown, in one specific embodiment of this utility model, the number of drainage ditches 5 is one. The number of drainage ditches 5 can also be multiple, with the multiple drainage ditches 5 arranged alternately. The term "multiple" refers to two or more; in another specific embodiment of this utility model, the number of drainage ditches 5 is three.
[0036] During construction, the sunken plaza renovation site will be located as follows: 6 Figure 1 and Figure 2 As shown in the example, the two buildings on the left and right are located on the ground, and there is a two-story basement below the ground. The sunken plaza renovation site 6 is located on the ground between the two buildings. The top slab, beams and columns of the first basement floor of the sunken plaza renovation site 6 are removed. Composite beam slabs 4 are set on the top surface of the beam 3 on the second basement floor, the top surface of the left top floor slab 1 on the second basement floor, and the top surface of the right top floor slab 2 on the second basement floor. Drainage ditch 5 is set in the top surface of the composite beam slab 4.
[0037] Therefore, by adopting this utility model, composite beams and slabs can be directly installed on the top surface of the beams on the second basement level, the top surface of the left top floor slab on the second basement level, and the top surface of the right top floor slab on the second basement level. For example, a 30cm thick concrete slab can be poured, which can basically meet the requirements for anti-buoyancy and the requirements for setting up drainage ditches. Most importantly, it is equivalent to raising the composite beam by 30cm. The load-bearing capacity of the original beams and slabs (i.e., the beams and top slabs of the second basement level) is no longer considered. The newly added composite beams and slabs are used as load-bearing slabs, and the load-bearing capacity of the beams and slabs is greatly improved. At the same time, the entire construction process is carried out on the surface of the original beams and slabs (i.e., the beams and top slabs of the second basement level), which is convenient and fast. The drainage, anti-buoyancy and load-bearing capacity meet the requirements.
[0038] In summary, the sunken plaza renovation structure of this utility model is simple in structure, meets the requirements for drainage, anti-buoyancy and load-bearing capacity, is easy to construct, has a short construction period and low construction cost, and is suitable for large-scale promotion and application.
[0039] Therefore, it is evident that the objective of this utility model has been fully and effectively achieved. The function and structural principles of this utility model have been demonstrated and explained in the embodiments. Without departing from the stated principles, any modifications can be made to the implementation methods. Therefore, this utility model includes all modified embodiments based on the spirit and scope of the claims.
