Description

Technical Field

[0001] This utility model relates to the field of modular integrated building technology, and in particular to a concrete module with a steel reinforcement cage. Background Technology

[0002] Modular integrated construction is an industrialized construction model that breaks down a building into standardized functional modules. These modules are prefabricated with high precision in a prefabrication plant, including structure, interior decoration, and equipment systems, and then transported to the construction site for rapid assembly. Through 3D design, the building is divided into concrete modules (such as room and kitchen / bathroom modules). Over 90% of the processes (including steel structure welding, concrete pouring, pipeline pre-embedding, and intelligent equipment integration) are completed on the prefabrication plant's assembly line. The modules are then transported to the construction site by truck or rail and assembled using heavy machinery. Only 10% of the on-site work is required to complete the entire building.

[0003] In existing technologies, modular integrated buildings are formed by assembling individual concrete modules. A large amount of steel reinforcement work needs to be completed on-site at the location of the cast-in-place concrete. This not only requires a lot of manpower but also delays the overall construction progress. However, if all the steel reinforcement work is done in the prefabrication plant, the structure of the concrete modules will become extremely complex. The traditional method of vertically dropping concrete and demolding it from the side cannot produce this concrete module, thus wasting a lot of time and slowing down the construction progress on site.

[0004] Therefore, there is an urgent need for a concrete module with a steel cage that allows for steel reinforcement work to be completed in a prefabrication plant. Utility Model Content

[0029] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1:

[0031] Reference Figure 1 and Figure 2This embodiment provides a concrete module with a reinforcing cage. The concrete module is used for modular integrated buildings, and the reinforcing work on the concrete module is completed during the prefabrication stage. The concrete module includes a prefabricated bottom slab, a prefabricated top slab 2, and multiple prefabricated side wall panels 1 arranged in a hexahedral layout. Specifically, the concrete module with a reinforcing cage in this embodiment includes multiple stirrups 3 embedded on one side of the adjacent prefabricated side wall panel 1 and distributed longitudinally at intervals, and multiple vertical bars 4 fixed in the stirrups 3, as detailed below.

[0032] In this embodiment, the vertical reinforcement 4 protrudes from the precast top slab 2. When two concrete modules are stacked vertically, the reinforcing cages in the upper and lower concrete modules are arranged vertically and vertically, with the lower vertical reinforcement 4 extending into the area where the bottom of the upper vertical reinforcement 4 is located. The bottom end of the vertical reinforcement 4 is at the same height as the bottom end of the concrete module, while the top end of the vertical reinforcement 4 is higher than the top end of the concrete module. By pre-embedding the stirrups 3 on the outside of the precast side wall panel 1, multiple vertical spaces are separated, and the vertical reinforcement 4 is fixedly connected to the stirrups 3 by welding, binding, or riveting. This allows the reinforcement work to be completed in the precast plant. During on-site construction, the upper and lower concrete modules can be connected simply by pouring concrete on the overlapping part of the upper and lower vertical reinforcement 4, saving labor and accelerating the overall construction speed.

[0033] In summary, by completing a large amount of on-site manual rebar work in the prefabrication plant and binding it to the prefabricated side wall panel 1 in the form of rebar cages, the overlapping parts of the vertical bars 4 can be connected by concrete pouring, which enhances the connection strength between the upper and lower concrete modules. This eliminates the need for on-site rebar work and speeds up the overall construction efficiency.

[0034] Furthermore, the multiple precast side wall panels 1 include a first precast side wall panel 11, a second precast side wall panel 12, a third precast side wall panel 13, and a fourth precast side wall panel 14. Reinforcing cages are provided on the outer side of the end of the third precast side wall panel 13 connecting to the second precast side wall panel 12, on the outer side of the end of the fourth precast side wall panel 14 connecting to the first precast side wall panel 11, and on the outer side of the corner of the second precast side wall panel 12. The third precast side wall panel 13 can connect adjacent concrete modules by pouring concrete in the adjacent space when connected to adjacent front and rear concrete modules. Similarly, the reinforcing cage on the fourth precast side wall panel 14 can connect adjacent left and right concrete modules by pouring concrete in the adjacent space when connected to adjacent left and right concrete modules. The reinforcing cage at the corner of the third precast side wall panel 13 connects the corners of four concrete modules together when multiple concrete modules are connected horizontally, thus increasing their strength.

[0035] Furthermore, multiple stirrups 3 are arranged side-by-side at intervals along the precast side wall panel 1 to form multiple rows, and the multiple stirrups 3 and the precast side wall panel 1 form multiple cavities, with multiple vertical bars 4 distributed inside the cavities. The stirrups 3 are arranged side-by-side in multiple rows along the outer side of the precast side wall panel 1 to form vertical cavities, and the multiple stirrups 3 are distributed and connected to the stirrups 3 within these cavities.

[0036] Furthermore, the spacing between two vertically adjacent stirrups 3 is within the range of 100mm-150mm. Maintaining a certain distance between two vertically adjacent stirrups 3 can ensure the strength of the concrete module after the concrete is poured, prevent the stirrups 3 from being wasted, and also provide a suitable position for fixing the vertical reinforcement 4.

[0037] Furthermore, the stirrup 3 is a composite stirrup. A composite stirrup is typically composed of an outer layer of closed stirrups 3 and inner single-leg stirrups 3, tie bars, or other forms of stirrups 3 arranged according to certain rules, forming a multi-layered nested or intersecting stirrup system 3. This is done to enhance the confinement effect on concrete, improve the shear capacity, ductility, and seismic performance of the member, and effectively limit the propagation of concrete cracks and the slippage of reinforcing bars.

[0038] Furthermore, the vertical reinforcement 4 is divided into a first straight section 41, a broken section 42, and a second straight section 43. The first straight section 41 is located at the edge of the cavity and protrudes from the precast top slab 2. The first straight section 41 extends downward to the broken section 42, and the broken section 42 extends towards the center of the cavity to the second straight section 43. The second straight section 43 extends downward to the precast bottom slab and is located within the first straight section 41 in the lower reinforcement cage. The first straight section 41 is connected to the stirrups 3 at the edge of the cavity, while the broken section 42 bends towards the center of the cavity. The second straight section 43 extends downward near the center of the cavity to the height of the precast bottom slab, while the first straight section 41 protrudes from the precast top slab 2. Therefore, the second straight section 43 is located within the space formed by the first straight section 41 in the lower reinforcement cage.

[0039] Furthermore, the first straight section 41 protrudes from the precast top slab 2 at a height ranging from 450mm to 700mm. To ensure the connection strength between the upper and lower concrete modules, the first straight section 41 protrudes from the precast top slab 2 at a sufficient height, allowing the lower concrete module to form a whole through the overlap of the cast-in-place concrete and the vertical reinforcement 4, which is selected according to the diameter of the vertical reinforcement 4 and the type of concrete. In this embodiment, when C45 concrete is selected and the diameter of the vertical reinforcement 4 is 16mm, the first straight portion 41 protrudes from the precast top slab 2 at a height of not less than 550mm. When C60 concrete is selected and the diameter of the vertical reinforcement 4 is 16mm, the first straight portion 41 protrudes from the precast top slab 2 at a height of not less than 450mm. When C45 concrete is selected and the diameter of the vertical reinforcement 4 is 20mm, the first straight portion 41 protrudes from the precast top slab 2 at a height of not less than 700mm. When C60 concrete is selected and the diameter of the vertical reinforcement 4 is 20mm, the first straight portion 41 protrudes from the precast top slab 2 at a height of not less than 600mm.

[0040] Further ， The reinforcing cage is also surrounded by multiple outer stirrups, which are spaced vertically around the cage. The reinforcing cage consists of multiple rows of stirrups 3 arranged side by side and vertical bars 4 fixed inside the stirrups 3. Therefore, the reinforcing cage cannot be effectively fixed in the horizontal direction. When facing the pouring of concrete, it is prone to deformation and displacement due to the impact of the lateral cast-in-place concrete. Therefore, by surrounding the reinforcing cage with multiple outer stirrups, the reinforcing cage is fixed in shape to prevent deformation.

[0041] Example 2:

[0042] Reference Figure 3 The difference between this embodiment and embodiment 1 is that the stirrups 3 are fixed to the steel mesh 5 in the precast side wall panel 1, which enhances the integrity of the steel mesh 5 and the precast side wall panel 1, as detailed below.

[0043] In this embodiment, the precast side wall panel 1 is also provided with a vertically extending steel mesh 5, and one side of the stirrup 3 is fixed to the steel mesh 5. The stirrup 3 is fixedly connected to the steel mesh 5 by binding, welding or snapping, and the steel mesh 5 is distributed in the precast side wall panel 1 along the extension direction of the precast side wall panel 1, and is integrally formed by casting.

[0044] The specific process is as follows: When the precast base plate, precast top plate 2 and multiple precast side wall plates 1 are mass-produced in the precast plant, before the concrete is poured, multiple stirrups 3 are pre-embedded on the outside of the precast side wall plate 1 by fixing it to the steel mesh 5 therein. After the precast base slab, precast top slab 2, and multiple precast side wall panels 1 are fabricated, they need to be spliced ​​to form a concrete module. During the splicing process, a tooling platform is required. The tooling platform serves as the inner template for splicing. The precast base slab, precast top slab 2, and multiple precast side wall panels 1 can be spliced ​​into a concrete module using the tooling platform. The precast base slab is placed at the bottom of the tooling platform, and multiple precast side wall panels 1 are installed on the sides of the tooling platform in sequence. The multiple precast side wall panels 1 are connected to each other, the precast base slab, the precast outer wall panel, and the multiple precast side wall panels 1 using concrete. Then, the precast top slab 2 is placed at the top of the tooling platform, and the precast top slab 2 is connected to the multiple precast side wall panels 1 using concrete. The tooling platform is then removed through the holes in the concrete module, and multiple vertical bars 4 are fixed to the surface of the precast side wall panels 1 and the cavity formed by the stirrups 3 by welding or binding. After the vertical bars 4 are bound, multiple outer stirrups are vertically fixed around the perimeter of the reinforcing cage to maintain the shape of the reinforcing cage. The completed concrete modules are transported to the site, placed horizontally, and concrete is poured between multiple concrete modules to connect them horizontally. The upper and lower concrete modules are aligned one by one, and concrete is poured again. This process of placing the upper concrete modules and connecting them with the lower concrete modules is repeated until the predetermined floor height is reached, ultimately forming a multi-story modular integrated building.
