Abstract
Description
Technical Field
[0001] The invention relates to the technical field of building engineering, and in particular to a modular building floor system. Background Art
[0002] At present, with the acceleration of urbanization and the improvement of people's requirements for building quality, traditional construction methods can no longer meet the current social needs for construction speed, quality and environmental protection. As a new type of building form, steel structure modular buildings have gradually become an important development direction of the construction industry with their advantages of high efficiency, environmental protection and flexibility.
[0003] Steel structure modular buildings are widely used in residential, public buildings, hotels, wards and other fields. This building form uses steel structure as the supporting structure. Through modular design and factory prefabrication, the building is broken down into modules, which are assembled and installed on site, thus achieving efficient, fast and environmentally friendly construction of the building.
[0004] However, the prior art also has the following technical problems: (1) How to ensure that the connection between floor modules is safe and reliable is a technical difficulty. A loose connection may lead to safety hazards.
[0005] (2) The floor system needs to have good waterproof and fireproof properties to ensure the safety and durability of the building. However, in actual applications, the construction and maintenance of the waterproof layer and fireproof layer may be difficult.
[0006] (3) In some special cases, such as large spans and heavy loads, the bearing capacity of the modular building floor system may be limited.
[0007] (4) Although modular building floor systems have many advantages, their initial costs may be relatively high, including costs for factory construction, material procurement, transportation and installation. Summary of the invention
[0008] The object of the present invention is to provide a modular building floor system to solve at least one technical problem existing in the prior art.
[0009] In order to solve the above technical problems, the present invention provides a modular building floor system, comprising a first module and a second module; The first module is arranged above the second module, and the lower end of the first module is connected to the upper end of the second module.
[0010] Further, the first module includes a floor beam, a transverse floor frame beam, a longitudinal floor frame beam and a first column; The two oppositely disposed transverse bottom frame beams and the two oppositely disposed longitudinal bottom frame beams enclose a quadrilateral frame, and the four corners of the frame are connected to the first columns; The bottom plate beam is arranged longitudinally, and two ends thereof are respectively connected to the two oppositely arranged transverse bottom frame beams.
[0011] Further, the second module includes a top plate beam, a transverse top frame beam, a longitudinal top frame beam and a second column; The two oppositely arranged transverse top frame beams and the two oppositely arranged longitudinal top frame beams enclose a quadrilateral frame, and the four corners of the frame are connected to the second columns; The top plate beam is arranged transversely, and its two ends are respectively connected to the two longitudinal top frame beams arranged oppositely.
[0012] Further, the lower end surface of the longitudinal bottom frame beam, the lower end surface of the transverse bottom frame beam and the lower end surface of the bottom plate beam are on the same horizontal plane; The upper end surface of the longitudinal top frame beam and the upper end surface of the transverse top frame beam are on the same horizontal plane, and the horizontal plane is the upper end surface of the top plate beam; When the first module is connected to the second module, the lower end surface of the longitudinal bottom frame beam and the lower end surface of the transverse bottom frame beam abut against the upper end surface of the longitudinal top frame beam and the upper end surface of the transverse top frame beam respectively.
[0013] Furthermore, the first module also includes a peg; The bolt is directly or indirectly arranged on the lower end surface of the bottom beam; The second module also includes a grouting tube; The grouting tube is arranged on the upper end surface of the top plate beam, and its position is opposite to the position of the bolt; A concrete layer is arranged in the grouting tube; When the first module is connected to the second module, the bolt is inserted into the concrete layer in the grouting cylinder and forms a mechanical bite action with the concrete layer.
[0014] Furthermore, a threaded sleeve is provided on the lower end surface of the bottom plate beam; The inner side of the threaded sleeve is provided with a thread matching the bolt; The bolt is connected to the bottom plate beam through the threaded sleeve.
[0015] Furthermore, the grouting tube is surrounded by four trapezoidal steel plates on the upper surface of the top beam, and the top is open for pouring the concrete layer and inserting the bolts.
[0016] Furthermore, the height of the grouting barrel is on the same horizontal plane as the upper end surface of the longitudinal top frame beam and the upper end surface of the transverse top frame beam; When the first module is connected to the second module, the grouting tube enables the bottom plate beam and the top plate beam to work together to form a hollow truss.
[0017] Furthermore, the first module also includes a concrete surface layer and a corrugated steel plate; The corrugated steel plate is arranged on the bottom plate beam; The concrete surface layer is arranged on the corrugated steel plate.
[0018] By adopting the above technical solution, the present invention has the following beneficial effects: (1) By setting up a grouting tube and a bolt structure, the present application can make the top plate beam and the bottom plate beam work together to form a hollow truss, which can fully utilize the stiffness of the top plate beam and the bottom plate beam and enhance the integrity of the module structure.
[0019] (2) Compared with traditional composite floors, the thickness of the composite floor required to achieve the same stiffness, strength and comfort requirements will be greatly reduced due to the increase in the stiffness of the supporting structure under the composite floor of the first module (concrete surface layer and corrugated steel plate), which can reduce the use of steel and concrete and reduce the weight of the structure.
[0020] (3) The on-site construction and installation operation of the modular building floor system disclosed in the present application is relatively simple. It only requires screwing in bolts and pouring a small amount of concrete. There is no need to wait for the concrete to solidify and form strength before proceeding to the next construction operation, which does not affect continuous construction.
[0021] (4) In this application, the bolts are installed under the top beam, and the pouring of the composite floor and the installation of indoor ground pipelines and floors are not affected by on-site construction. Similarly, the grouting tube is located above the top beam, and the operation of pouring concrete has no effect on the ceiling. The module interior decoration project can be prefabricated and installed in the factory, and there is no need to reserve holes for on-site installation operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention is further explained below in conjunction with specific implementation modes.
[0030] Example 1 like Figure 1-2 As shown, a modular building floor system provided in this embodiment includes a first module 1 and a second module 2; The first module 1 is disposed above the second module 2 , and the lower end of the first module 1 is connected to the upper end of the second module 2 .
[0031] like Figure 1 , 3 As shown, as a further implementation of this embodiment, the first module 1 includes a bottom plate beam 11, a transverse bottom frame beam 12, a longitudinal bottom frame beam 13 and a first column 14; The two oppositely disposed transverse bottom frame beams 12 and the two oppositely disposed longitudinal bottom frame beams 13 enclose a quadrilateral frame, and the four corners of the frame are connected to the first columns 14; The bottom plate beam 11 is longitudinally arranged, and two ends thereof are respectively connected to the two oppositely arranged transverse bottom frame beams 12 by welding or other connection methods.
[0032] In addition to being arranged at the four corners of the frame, the first columns 14 may also be arranged at other positions of the frame to improve the supporting capacity of the first module 1 .
[0033] like Figure 2 , 3 As shown, as a further implementation of this embodiment, the second module 2 includes a top plate beam 21, a transverse top frame beam 22, a longitudinal top frame beam 23 and a second column 24; The two oppositely disposed transverse top frame beams 22 and the two oppositely disposed longitudinal top frame beams 23 enclose a quadrilateral frame, and the four corners of the frame are connected with the second columns 24; The top plate beam 21 is arranged transversely, and two ends thereof are respectively connected to the two oppositely arranged longitudinal top frame beams 23 by welding or other connection methods.
[0034] In addition to being arranged at the four corners of the frame, the second column 24 may also be arranged at other positions of the frame to improve the supporting capacity of the second module 2 .
[0035] The bottom plate beam 11 and the top plate beam 21 are respectively arranged longitudinally and transversely, so that the bottom plate beam 11 and the top plate beam 21 present a mutually perpendicular position structure in a top view.
[0036] like Figure 3-5As shown, as a further implementation of this embodiment, the lower end surface of the longitudinal bottom frame beam 13, the lower end surface of the transverse bottom frame beam 12 and the lower end surface of the bottom plate beam 11 are on the same horizontal plane; The upper end surface of the longitudinal top frame beam 23 and the upper end surface of the transverse top frame beam 22 are on the same horizontal plane, which is the upper end surface of the top plate beam 21; like Figure 4-5 As shown, when the first module 1 is connected to the second module 2, the lower end surface of the longitudinal bottom frame beam 13 and the lower end surface of the transverse bottom frame beam 12 are respectively abutted against the upper end surface of the longitudinal top frame beam 23 and the upper end surface of the transverse top frame beam 22, that is, through the support of the longitudinal top frame beam 23 and the transverse top frame beam 22, a hollow area appears between the first module 1 and the second module 2.
[0037] like Figure 4-5 As shown, as a further implementation of this embodiment, the first module 1 further includes a bolt 31; The bolt 31 is directly or indirectly arranged on the lower end surface of the bottom beam 11; The second module 2 further includes a grouting tube 32; The grouting tube 32 is arranged on the upper end surface of the top plate beam 21, and its position is opposite to the position of the bolt 31; A concrete layer 33 is provided in the grouting tube 32; When the first module 1 is connected to the second module 2 , the bolt 31 is inserted into the concrete layer 33 in the grouting tube 32 and forms a mechanical bite action with the concrete layer 33 .
[0038] like Figure 4-5 As shown, as a further implementation of this embodiment, a threaded sleeve 34 is provided on the lower end surface of the bottom beam 11; The inner side of the threaded sleeve 34 is provided with a thread matching the bolt 31; The bolt 31 is connected to the floor beam 11 via the threaded sleeve 34 .
[0039] As a further implementation of this embodiment, the grouting tube 32 is surrounded by four trapezoidal steel plates on the upper surface of the top plate beam 21, and its top is open for pouring the concrete layer 33 and inserting the bolts 31.
[0040] like Figure 3-5 As shown, as a further implementation of this embodiment, the height of the grouting tube 32 is on the same horizontal plane as the upper end surface of the longitudinal top frame beam 23 and the upper end surface of the transverse top frame beam 22; When the first module 1 is connected to the second module 2, the grouting tube 32 enables the bottom plate beam 11 and the top plate beam 21 to work together to form a hollow truss. like Figure 3-5 As shown, as a further implementation of this embodiment, the first module 1 further includes a concrete surface layer 41 and a corrugated steel plate 42; The corrugated steel plate 42 is arranged on the bottom plate beam 11; The concrete surface layer 41 is disposed on the corrugated steel plate 42 .
[0041] The concrete surface layer 41 and the corrugated steel plate 42 constitute a composite floor slab. The corrugated steel plate 42 is made of a profiled steel plate and is connected to the bottom plate beam 11 by welding.
[0042] As a preferred implementation of this embodiment, the first module and the second module have the same structure, and the upper structures of the first module and the second module are as follows: Figure 1 As shown, the lower structures of the first module and the second module are as shown Figure 2 As shown, the upper and lower parts are connected by a column, and the identification of "first module" and "second module" in this application is only to illustrate the connection structure and should not be narrowly understood as an independent component.
[0043] In the modular building floor system of the present application, except for pouring the concrete layer 33 in the grouting tube 32 and installing the stud 31 in the threaded sleeve 34, the other components of the first module 1 and the second module 2 are installed in the factory. After the first module 1 and the second module 2 are transported to the site, concrete is poured into the grouting tube 32 of the second module 2 to form a concrete layer 33, and the stud 31 is installed in the threaded sleeve 34 before the concrete solidifies, and the first module 1 is hoisted onto the second module 2, and the stud 31 is inserted into the concrete layer 33 in the grouting tube 32. When the concrete layer 33 solidifies, the mechanical bite between the stud 31 and the concrete layer 33 can improve the connection performance. In addition, the grouting tube 32 structure is arranged in the hollow area between the first module 1 and the second module 2, so that the bottom plate beam 11 and the top plate beam 21 work together and form a hollow truss, so that the stiffness of the top plate beam 21 and the bottom plate beam 11 can be fully utilized, and the integrity of the module structure is enhanced. Since the rigidity of the whole modular structure is maximized, the rigidity requirement of the floor slab can be reduced when the floor slab is laid thereon, thereby greatly reducing the amount of steel and concrete required for the floor slab and reducing the weight of the structure. During on-site construction, the prior art generally requires waiting for the concrete to solidify before proceeding to the next step, while in the present application, the next step of construction can be carried out before the concrete solidifies, without affecting the continuous construction. This is because when the first module 1 and the second module 2 of the present application are installed in the vertical direction, the longitudinal top frame beam 23 and the transverse top frame beam 22 provide the support force required for the constant load, and the live load can be ignored during the construction process. Therefore, the outer wall of the grouting tube 32 can meet the support force required by the bottom plate beam 11 and the top plate beam 21 during the construction process, and when the concrete layer 33 solidifies, a hollow truss with greater rigidity can be formed, which has the ability to support the live load. Finally, the installation bolts 31 required by the present invention are under the top plate beam 21, and the pouring of the combined floor slab and the installation of indoor ground pipelines and floors are not affected by on-site construction. Similarly, the grouting tube 32 is located above the top plate beam 21, and the operation of pouring concrete has no effect on the ceiling. The module interior decoration project can be prefabricated and installed in the factory, and there is no need to reserve holes for on-site installation operations.
[0044] By adopting the above technical solution, the present invention has the following beneficial effects: (1) Through modular design, the first module 1 and the second module 2 can be prefabricated in the factory, which greatly reduces the complexity and time cost of on-site construction and improves construction efficiency.
[0045] (2) The first module 1 and the second module 2 form a stable and strong structural system through careful structural design, such as the connection between the bottom plate beam 11, the top plate beam 21 and the frame beam and column, and the mechanical bite between the concrete layer 33 in the grouting tube 32 and the bolts 31, thereby enhancing the stability and bearing capacity of the overall structure.
[0046] (3) This technical solution makes full use of the mechanical properties of the material through reasonable structural design. For example, the hollow truss structure formed by the bottom plate beam 11 and the top plate beam 21 working together not only improves the rigidity of the structure, but also optimizes the utilization of materials and reduces costs.
[0047] (4) The hollow area formed by connecting the first module 1 and the second module 2 not only provides more space possibilities inside the building, such as pipeline layout, equipment installation, etc.
[0048] (5) Through the mechanical bite action of the concrete layer 33 in the grouting tube 32 and the bolt 31, and the close fit between the threaded sleeve 34 and the bolt 31, a reliable connection between the first module 1 and the second module 2 is achieved, thereby improving the integrity and durability of the structure.
[0049] (6) The modular design allows parts of the building to be maintained and upgraded without affecting the overall structure, improving the flexibility and maintainability of the building.
[0050] (7) The system makes full use of the stiffness of the bottom plate beam 11 and the top plate beam 21 to form a hollow truss structure, which reduces the requirements for the stiffness of the floor slab, thereby reducing the amount of steel and concrete, reducing the weight of the structure and reducing costs.
[0051] (8) The next step of construction can be carried out before the concrete solidifies. Since the longitudinal top frame beam 23 and the transverse top frame beam 22 provide the supporting force required for the constant load, the continuous construction process is not affected, thereby improving the construction efficiency.
[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
