Description

Technical Field

[0001] This utility model relates to the field of modular building technology, specifically a concrete modular building structure system. Background Technology

[0002] Modular concrete building structures decompose a building structure into several standardized concrete modules, which are prefabricated in a factory and then transported to the construction site for assembly. They offer advantages such as rapid construction, high integration, convenient construction, resource conservation, and flexible application. Existing modular concrete building structures typically use solid slabs or beam-supported structures, with the concrete modules partially or fully participating in the structural load-bearing. The formwork, acting as the sidewall of the cast-in-place structure, needs sufficient strength and stability, thus requiring a relatively thick formwork. This increases the mass of the concrete modules, raising the risk of foundation settlement or deformation and affecting the stability and safety of the structure. Furthermore, the cumulative errors from module prefabrication and construction can lead to excessive errors at higher levels, making installation impossible and requiring work stoppages for horizontal and vertical adjustments. Utility Model Content

[0003] The purpose of this utility model is to provide a modular concrete building structure system to solve the problems of the prior art mentioned in the background.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A modular concrete building structure system includes a main structure and a secondary structure. The main structure includes several slabs, columns, and floor slabs. The floor slabs are located on top of the slabs and columns and are hollow floor slabs. The secondary structure is composed of several concrete modules. A connecting member is provided between the secondary structure and the main structure. The connecting member is a flexible connecting member. The secondary structure serves as an energy-dissipating component of the main structure.

[0006] Furthermore, the main structure also includes shear walls, which are distributed longitudinally along each column of the slab columns.

[0007] Furthermore, the concrete module is a cubic structure composed of a top plate, side plates, bottom plate, front plate, and back plate. The side plates are provided with side grooves, and the area of ​​the side grooves is 30-50% of the total area of ​​the side plates.

[0008] Furthermore, the surface of the side groove is a rough surface, and a number of truss steel bars are provided on the rough surface. The truss steel bars are also provided with a number of reinforcing nodes, and the reinforcing nodes are symmetrically arranged V-shaped structures.

[0009] Furthermore, the side plate connection surfaces of adjacent concrete modules or the connection surfaces between the side plates and the shear wall are all connected by grouting.

[0010] Furthermore, the flexible connector is a rubber support, a spring device, or a damper.

[0011] Furthermore, the hollow floor slab includes an outer protective shell and an inner hollow layer. The protective shell is a concrete shell, and the hollow layer adopts a honeycomb or grid structure.

[0012] Furthermore, the hollow layer is filled with sound-insulating and heat-insulating materials.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The concrete module consists of a top slab, side slabs, a bottom slab, a front panel, and a back panel. The side slabs have side grooves, with the groove area accounting for 30-50% of the total area of ​​the side slab. This groove design reduces concrete usage and the module's self-weight. Simultaneously, the strength and stability of the side slabs are ensured by truss reinforcement and strengthened joints. The main structure and secondary structure are connected by flexible connectors, allowing the secondary structure to deform within a certain range. This reduces the rigid constraints of the secondary structure on the main structure, enabling the secondary structure to absorb and dissipate energy as an energy-dissipating component, without relying entirely on the module's own stiffness to bear the load. Furthermore, the open-web floor slab design significantly reduces the self-weight of the floor slab, lowering the overall structural load and reducing the risk of foundation settlement or deformation, thus ensuring the stability and safety of the overall structure.

[0015] Grouting is used to connect concrete modules or between modules and shear walls. This method provides a certain degree of tolerance and can adjust the positional deviations between modules to a certain extent, reducing the accumulation of errors. At the same time, flexible connectors such as rubber supports, spring devices, or dampers also have a certain deformation capacity, which can absorb and adjust construction errors and avoid installation difficulties caused by error accumulation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] A modular concrete building structure system includes a main structure 100 and a secondary structure 200. The main structure 100 includes several slabs and columns 110 and a floor slab 120. The floor slab 120 is located on top of the slabs and columns 110 and is a hollow floor slab 120. The main structure 100 has no beams inside, which increases the clear height. The secondary structure 200 is composed of several concrete modules. A flexible connector is provided between the secondary structure 200 and the main structure 100. The secondary structure 200 serves as an energy-dissipating component of the main structure 100. The hollow design of the floor slab 120 reduces its self-weight. Since the main structure 100 has no beams inside, the corresponding concrete modules do not need to have beam recesses, simplifying the prefabrication process and increasing standardization. The concrete modules are not connected by the main structure 100, thus not occupying usable space and ensuring a clear force transmission path between the main structure 100 and the secondary structure 200, resulting in a more rational stress distribution of the overall structure.

[0024] The main structure 100 also includes shear walls 130, which are distributed longitudinally along each column of the slab columns 110 to ensure the lateral force resistance of the overall structure.

[0025] The concrete module is a cubic structure composed of a top plate 230, a side plate 220, a bottom plate, a front plate 210, and a back plate. The side plate 220 is provided with a side groove 221, and the area of ​​the side groove 221 is 30 to 50% of the total area of ​​the side plate 220.

[0026] The surface of the side groove 221 is a rough surface 222, which increases the friction of the contact surface, improves the adhesion between the concrete and the freshly poured concrete or grout, and prevents slippage. Several truss steel bars 223 are provided on the rough surface 222 to provide mechanical interlocking force and further enhance the bonding performance. Several reinforcing nodes 224 are also provided on the truss steel bars 223. The reinforcing nodes 224 are symmetrically arranged V-shaped structures. Through the V-shaped structure, the connection between the surface of the side plate 220 of the adjacent concrete module or the connection surface between the back plate and the plate column 110 is enhanced, thereby improving the overall seismic resistance and deformation resistance.

[0027] The connection surfaces of the side plates 220 of adjacent concrete modules or the connection surfaces of the side plates 220 and the shear wall 130 are all connected by grouting, so that the connection surfaces are tightly connected, with strong integrity and good seismic performance.

[0028] The flexible connector is a rubber support, a spring device, or a damper.

[0029] The hollow floor slab includes an outer protective shell and an inner hollow layer. The protective shell is a concrete shell, and the hollow layer adopts a honeycomb or grid structure. The hollow floor slab not only reduces the structural weight, but also reduces the use of materials and lowers costs. Moreover, since there is no need to set beam sockets, the production process is simpler and it is suitable for large-scale prefabrication.

[0030] The hollow layer is filled with sound insulation and heat insulation materials, giving the modular concrete building good sound insulation and heat insulation performance, and improving the building's comfort.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
