Description

Technical Field

[0001] The utility model relates to the field of assembled buildings, in particular to a prefabricated assembled reinforcement structure of a basement floor. Background Art

[0002] During the process of building renovation, it is common to add or reduce floors, add or remove columns and walls indoors, which will involve the increase or decrease of the load under the columns and walls. The increase of the load under the columns and walls may lead to insufficient foundation bearing capacity and foundation slab reinforcement, while the reduction of the load under the columns and walls may lead to insufficient anti-floating problems. For the problem of insufficient reinforcement of the foundation slab, there are several conventional solutions, depending on the situation: sticking steel plates or carbon fiber cloth on the surface of the foundation slab to increase the bearing capacity of the foundation slab (such as Figure 1 to Figure 4 As shown in the figure), adding a superimposed layer on the foundation slab surface to increase the thickness of the foundation slab to improve the bearing capacity of the foundation slab (as shown in the figure Figure 5-6 As shown in the figure), when controlling the anti-floating condition, pile foundations or anchor rods are added to reduce the load span of the foundation slab (as shown in the figure). Figure 7-8 shown).

[0003] However, the above methods all have problems: the first method, on the one hand, insufficient reinforcement of the foundation slab is usually accompanied by insufficient foundation slab surface and foundation slab bottom. Insufficient reinforcement of the bottom slab cannot be solved by sticking steel plates or carbon fibers on the bottom of the foundation slab, otherwise there will be problems such as knocking the existing foundation slab and damaging the waterproofing of existing buildings. On the other hand, if the bottom slab concrete is modulated to increase the reinforcement of the bottom slab surface, since the foundation slab often has a waterproof function at the same time, its waterproof performance will be reduced and even leakage will be caused. The second method can effectively reduce the calculated reinforcement, and the force-bearing steel bars on the foundation slab surface can also be added in the superimposed layer. However, this method increases the structural reinforcement ratio of the foundation slab while increasing the thickness of the slab. The bottom steel bars of the foundation slab of existing buildings often have insufficient structural reinforcement ratio. On the other hand, adding a superimposed layer to the slab surface will have a certain impact on the normal use of existing buildings and indoor clearance. The third method can effectively reduce the stress on the foundation slab when controlling anti-floating conditions. However, when constructing pile foundations or anchor rods in existing buildings, there are problems such as limited operating space and difficult operations. It also causes certain damage to the waterproofing of existing buildings. Utility Model Content

[0032] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0034] like Fig. 9 As shown, the utility model discloses a prefabricated and assembled reinforcement structure of a basement floor, comprising a basement floor 1 and a basement top 2, and a basement column 3 located between the basement floor 1 and the basement top 2, and a prefabricated and assembled vertical component 4 fixedly connected to the four sides of the basement column 3, wherein the prefabricated and assembled vertical component 4 is vertically connected to any side surface of the four sides of the basement column 3. The prefabricated and assembled vertical components 4 can be arranged in pairs on two opposite sides of the basement column 3; or the prefabricated and assembled vertical components 4 can be arranged on any three sides of the basement column 3; or the prefabricated and assembled vertical components 4 can be arranged on the four sides of the basement column 3 in a cross shape.

[0035] The utility model adopts a reinforcement method of adding prefabricated assembled vertical components. When the vertical shear wall 41 is used, the vertical shear wall 41 will support the beams and plates located in the basement top plate 2, which can reduce the calculated span of the beams and plates in the basement top plate 2 and reduce the reinforcement workload of the beams and plates. However, at the same time, the force transmission path of the beams and plates is changed. The top longitudinal reinforcement of the beams and plates may be insufficient under the support of the vertical shear wall 41. When the beams and plates located in the basement top plate 2 do not need to be reinforced, the inclined shear wall 42, vertical corbel 43 or inclined corbel 44 can be considered. The above three methods are not in direct contact with the beams and plates located in the basement top plate 2, and the force transmission path of the beams and plates components is not changed, which can effectively avoid the problem of insufficient top longitudinal reinforcement of beams and plates components due to the increase of local support. It can be seen that the utility model can better adapt to different parts, different working conditions, different application scenarios, different cost investment and other situations through changing forms.

[0036] like Figure 10-11As shown, the connection method of the prefabricated vertical component 4 and the basement column 3 includes: the prefabricated vertical component 4 is vertically connected by implanting the shear reinforcement 51 into the basement column 3; or the prefabricated vertical component 4 is vertically connected to the basement column 3 through the shear key 52. ​​The prefabricated vertical component added by the utility model is fixedly connected by shear reinforcement or shear key, which is conducive to green construction and easy to promote. At the same time, it also avoids the problems of on-site concrete pouring in existing buildings, construction quality assurance and construction difficulties.

[0037] In one embodiment, Figure 12-13 As shown, the prefabricated vertical component 4 is a vertical shear wall 41 or an inclined shear wall 42. In another embodiment, as Figure 14-15 As shown, the prefabricated vertical component 4 is a vertical corbel 43 or an inclined corbel 44. Various forms of prefabricated vertical components can reduce the impact on adjacent components.

[0038] The present invention does not adopt the traditional reinforcement method of "treating the symptoms rather than the root cause", such as in-situ gluing steel, in-situ gluing carbon fiber cloth, in-situ increasing the cross-section or in-situ adding pile foundations to insufficiently reinforced plate components. Instead, it reduces the calculated reinforcement and solves the problem of insufficient reinforcement by changing the force transmission path of the component from the original force angle of the component, thereby reducing the force span of the plate component and further reducing the bending moment it is subjected to. At the same time, the present invention utilizes the variable forms of variable-section inclined walls, cross-shaped column bottoms, and corbels at the bottom of column to adapt to different parts, different working conditions, different application scenarios, different cost investments, etc. In addition, the present invention does not change the force on the top beams and plate components, that is, there is no need to add additional reinforcement components.

[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
