Description

Technical Field

[0001] The present invention relates to the technical field of modular building structures, and in particular to a modular earthquake-resistant composite beam structure, a modular building structure and a construction method. Background Art

[0002] Modular building is a highly integrated prefabricated assembly system that uses modular assembly to build buildings. In the traditional modular building structure system, the modules are connected through horizontal connecting plates and connection nodes set between columns. This connection method makes the modular building form a "stacked beam and column" structure. The mechanical properties of the beam components in this upper and lower separated independent double beam structure are difficult to be fully utilized, resulting in a waste of materials and building space; at the same time, the floor beams and ceiling beams of the upper and lower modules are separated from each other, resulting in low overall lateral stiffness and poor stability of the modular building structure, and insufficient structural seismic performance; the force transmission path between modules is single and the connection is weak, and there is a problem of discontinuous floor slabs. The construction height of the modular building structure is limited, and it is difficult to meet the high performance requirements of the high-rise modular integrated building structure system.

[0003] Therefore, it is necessary to study a new type of modular seismic-resistant composite beam structure to optimize the stacked beam structure in traditional modular buildings, effectively improve the overall stiffness and bearing capacity of the modular beams, reduce material waste, optimize space utilization, solve the problem of floor discontinuity, enhance the overall stability of the structure, and improve the seismic performance of modular buildings.

[0013] In a second aspect, the present invention further provides a modular building structure, comprising the modular seismic composite beam structure, and also comprising a column; One end of the first floor beam and the second floor beam in the length direction is fixed to two horizontally adjacent columns located above in a one-to-one correspondence, and one end of the first ceiling beam and the second ceiling beam in the length direction is fixed to two horizontally adjacent columns located below in a one-to-one correspondence, so as to connect four upper and lower adjacent modules; or, One end of the first floor beam and the second floor beam in the length direction is fixed to the same column above, and one end of the first ceiling beam and the second ceiling beam in the length direction is fixed to the same column below to connect two adjacent modules above and below.

[0014] In a third aspect, the present invention further provides a construction method, which is applied to the modular building structure, and the construction method comprises the following steps: S1. During processing, the inter-beam connecting member is arranged on the first floor beam, the second floor beam, the first ceiling beam and the second ceiling beam; Fix one end of the first floor beam and the second floor beam in the length direction to two horizontally adjacent columns located above one by one; or fix one end of the first floor beam and the second floor beam in the length direction to the same column located above, and fix one end of the first ceiling beam and the second ceiling beam in the length direction to the same column located below; S2. When assembling the module on site, the first floor beam and the second floor beam are arranged relative to each other, and the first ceiling beam and the second ceiling beam are arranged relative to each other, and the top of the first ceiling beam is attached to the bottom of the first floor beam, and the top of the second ceiling beam is attached to the bottom of the second floor beam; S3. Concrete is poured into the grouting cavity formed between the first floor beam and the second floor beam and between the first ceiling beam and the second ceiling beam. The inter-beam connecting piece and the concrete connect the first floor beam and the second floor beam, the first ceiling beam and the second ceiling beam, the first floor beam and the first ceiling beam, and the second floor beam and the second ceiling beam to form an overall modular seismic-resistant composite beam structure, and then form a modular building structure.

[0015] The beneficial effects of the modular seismic-resistant composite beam structure provided by the present invention are: Forming an integral composite beam to improve the mechanical properties of the module beam: when assembling the composite beam, the two floor beams are arranged oppositely, the two ceiling beams are arranged oppositely, and the two ceiling beams are arranged correspondingly at the bottom of the two floor beams, and the inter-beam connectors are arranged in the grouting cavity formed between the first floor beam and the second floor beam and between the first ceiling beam and the second ceiling beam, and the inter-beam connectors and the concrete are connected: the first floor beam and the second floor beam, the first ceiling beam and the second ceiling beam, the first floor beam and the first ceiling beam, and the second floor beam and the second ceiling beam, so as to realize the continuous connection of the two floor beams and the two ceiling beams in the two horizontal modules, and the continuous connection of the floor beams and the ceiling beams in the upper and lower modules, so as to form an integral composite beam. This embodiment enables the upper and lower separated independent double beam structure to form an integral composite beam structure with ceiling beams and floor beams cooperating in force, effectively improving the overall stiffness and bearing capacity of the module beam, giving full play to the mechanical properties of the component, and improving the effective utilization rate of the material.

[0016] Reduce material costs and increase the effective use area inside the module: By making the floor beam and the ceiling beam form an integral composite beam, the overall cross-sectional height of the composite beam is increased, and the cross-sectional stiffness of the composite beam is effectively improved. Under the premise of maintaining the original stiffness of the component, the cross-sectional size of the modular seismic composite beam structure can be reduced accordingly, so as to reduce the cross-sectional height of the floor beam and the ceiling beam under the premise of a certain overall floor height of the modular building structure, increase the effective use area inside the module, and the reduction in size can also save the production cost of the beam, thereby reducing the construction cost.

[0017] Realize independent adjustment of module beam stiffness and bearing capacity: By setting the upper and lower connectors between the ceiling beam and the floor beam, the previously separated ceiling beam and floor beam can be combined to form an integrated composite beam structure that bears force in coordination. By changing the height of the upper and lower connectors, the height of the grouting cavity between the first floor beam and the second floor beam can be changed, so that the upper and lower connection strength of the composite beam can be adjusted, and then the bearing capacity of the composite beam can be adjusted. When the connection strength reaches the limit, the connector fails, the upper and lower module beams are separated, and the bearing capacity of the beam section is reduced, so that the bearing capacity of the composite beam can be independently adjusted under the premise of unchanged stiffness.

[0018] Improve the integrity, stability and seismic resistance of modular building structures: form an overall composite beam structure with coordinated force, increase the force transmission path of the modular building structure, reduce the force load on the connection nodes between columns and the horizontal connecting plates, and achieve the continuity between the floor slabs fixed by two adjacent beams, thereby improving the integrity and stability of the modular building structure, especially enhancing the connection strength between horizontally adjacent modules and upper and lower modules, so as to improve the seismic resistance of the modular building structure and meet the high performance requirements of the high-rise modular integrated building structure system.

[0019] Improve on-site construction efficiency: When used on-site, by pouring concrete into the grouting cavity formed between the first floor beam and the second floor beam and between the first ceiling beam and the second ceiling beam, the floor beams and ceiling beams arranged above and below can be connected in conjunction with the beam connectors to achieve an integrated pouring operation, thereby improving on-site construction efficiency.

DETAILED DESCRIPTION

[0022] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific embodiments. Figure 1 The orientation is used as a reference.

[0023] Example 1

[0024] See also Figures 1 to 3 A modular seismic-resistant composite beam structure proposed in an embodiment of the present invention includes a first floor beam 1, a second floor beam 2, a first ceiling beam 3, a second ceiling beam 4 and connecting members between beams.

[0025] The first floor beam 1 and the second floor beam 2 are arranged opposite to each other, and the first ceiling beam 3 and the second ceiling beam 4 are arranged opposite to each other. The first ceiling beam 3 and the second ceiling beam 4 are arranged correspondingly at the bottom of the first floor beam 1 and the second floor beam 2. A grouting cavity is formed between the first floor beam 1 and the second floor beam 2 and between the first ceiling beam 3 and the second ceiling beam 4. The grouting cavity is used for pouring concrete.

[0026] The inter-beam connector is arranged in the grouting cavity, and is used to connect the first floor beam 1 and the second floor beam 2, the first ceiling beam 3 and the second ceiling beam 4, the first floor beam 1 and the first ceiling beam 3, and the second floor beam 2 and the second ceiling beam 4.

[0027] The modular seismic-resistant composite beam structure provided in this embodiment has the following effects: Forming an integral composite beam structure to improve the mechanical properties of the module beams: When assembling the composite beams, the two floor beams are arranged oppositely, the two ceiling beams are arranged oppositely, and the two ceiling beams are arranged correspondingly at the bottom of the two floor beams, and the inter-beam connectors are arranged in the grouting cavity formed between the first floor beam 1 and the second floor beam 2 and between the first ceiling beam 3 and the second ceiling beam 4, and the first floor beam 1 and the first ceiling beam 3, and the second floor beam 2 and the second ceiling beam 4 are connected by the inter-beam connectors and concrete 8 to achieve continuous connection of the two floor beams and the two ceiling beams in the two horizontal modules, and continuous connection of the floor beams and the ceiling beams in the upper and lower modules, to form an integral composite beam. This embodiment enables the upper and lower separated independent double beam structure to form an integral composite beam structure with ceiling beams and floor beams that are synergistically stressed, giving full play to the mechanical properties of the components and improving the effective utilization rate of materials.

[0028] Reduce material costs and increase the effective use area inside the module: By making the floor beam and the ceiling beam form an integral composite beam, the overall cross-sectional height of the composite beam is increased, and the cross-sectional stiffness of the composite beam is effectively improved. On the premise of maintaining the stiffness of the original components, the cross-sectional size of the modular seismic composite beam structure can be reduced accordingly, so as to reduce the cross-sectional height of the floor beam and the ceiling beam under the premise of a certain overall floor height of the modular building structure, increase the effective use area inside the module, and the reduction in size can also save the production cost of the beam, thereby reducing the construction cost.

[0029] Improve the integrity, stability and seismic resistance of modular building structures: form an overall composite beam structure with coordinated force, increase the force transmission path of the modular building structure, reduce the force load on the connection nodes between columns and the horizontal connecting plates, and achieve the continuity between the floor slabs fixed by two adjacent beams, thereby improving the integrity and stability of the modular building structure, especially enhancing the connection strength between horizontally adjacent modules and upper and lower modules, so as to improve the seismic resistance of the modular building structure and meet the high performance requirements of the high-rise modular integrated building structure system.

[0030] Improve on-site construction efficiency: When used on-site, by pouring concrete into the grouting cavity formed between the first floor beam 1 and the second floor beam 2 and between the first ceiling beam 3 and the second ceiling beam 4, the floor beams and ceiling beams arranged above and below can be connected in conjunction with the beam connectors to achieve an integrated pouring operation and improve on-site construction efficiency.

[0031] Furthermore, the inter-beam connecting member includes a first horizontal connecting member 51 and upper and lower connecting members 52 .

[0032] The first horizontal connector 51 extends horizontally from the opposite side walls of the first floor beam 1 and the second floor beam 2, and the first ceiling beam 3 and the second ceiling beam 4, and is staggered with each other. Thus, the first horizontal connector 51 can connect the two floor beams and the two ceiling beams through the concrete poured between the two floor beams and the two ceiling beams, so as to realize the continuous connection of the two floor beams and the two ceiling beams in the two horizontal modules, and further realize the continuity of the two horizontally adjacent floor slabs. At the same time, the horizontal staggered overlap of the first horizontal connector 51 extending horizontally can offset the lateral bending moment acting on the two floor beams and the two ceiling beams respectively, ensuring the lateral stiffness of the modular seismic composite beam structure, and further ensuring the lateral stiffness of the overall modular building structure, and ensuring the connection strength in the horizontal direction between the two floor beams and the two ceiling beams, avoiding separation when bearing horizontal tension.

[0033] The upper and lower connecting members 52 are arranged on the top of the first ceiling beam 3 and the second ceiling beam 4, and extend upward to the grouting cavity between the first floor beam 1 and the second floor beam 2. The upper and lower connecting members 52 are combined with the concrete poured between the floor beam and the ceiling beam to connect the upper and lower floor beams and ceiling beams, and can combine the originally separated ceiling beams and floor beams to form an integral composite beam structure that is synergistically stressed, thereby ensuring the connection strength between the upper and lower floor beams and ceiling beams, avoiding separation when bearing vertical tension, and avoiding horizontal separation when bearing lateral bending moment between the floor beams and ceiling beams, thereby ensuring the lateral stiffness between the floor beams and ceiling beams, and further ensuring the lateral stiffness of the overall modular building structure.

[0034] Specifically, to realize that the upper and lower connecting members 52 connect the upper and lower corresponding floor beams and ceiling beams: The bottom width of the first floor beam 1 is smaller than the top width of the first ceiling beam 3, and the bottom width of the second floor beam 2 is smaller than the top width of the second ceiling beam 4, so that the upper and lower connecting pieces 52 fixed on the tops of the first ceiling beam 3 and the second ceiling beam 4 can extend upward to the grouting cavity between the first floor beam 1 and the second floor beam 2.

[0035] Preferably, the height of the upper and lower connecting members 52 is adjustable to achieve independent adjustment of the module beam stiffness and bearing capacity: By changing the height of the upper and lower connecting members 52, the height of the grouting cavity between the upper and lower connecting members 52 extending upward to the first floor beam 1 and the second floor beam 2 can be changed, so that the upper and lower connection strengths of the composite beam structure can be adjusted, and then the bearing capacity of the composite beam can be adjusted. When the connection strength reaches the limit, the connecting member fails, the upper and lower module beams are separated, and the bearing capacity of the beam section is reduced. Therefore, the bearing capacity of the composite beam can be independently adjusted under the premise of unchanged stiffness.

[0036] During actual processing, the upper and lower connecting members 52 of different lengths can be replaced to adjust the length thereof.

[0037] Preferably, in order to further improve the bearing strength of the modular seismic-resistant composite beam structure, the modular seismic-resistant composite beam structure further includes a second horizontal connecting member 53 .

[0038] The second horizontal connecting member 53 is fixed on the column 7 and extends horizontally to the grouting cavity, and is used to connect the first floor beam 1, the second floor beam 2, the first ceiling beam 3 and the second ceiling beam 4 to the column 7, so as to improve the connection strength between the floor beam and the ceiling beam and the column 7 respectively, thereby improving the bearing strength of the modular seismic composite beam structure and improving the overall stability and seismic resistance of the modular building structure.

[0039] Preferably, in order to further improve the bonding force between the floor beam and the ceiling beam and the concrete in the grouting cavity, the modular seismic composite beam structure further includes a first reinforcement member 54 and a second reinforcement member 55: The first reinforcement 54 is fixed to the inner side of the top of the first floor beam 1 and the second floor beam 2 and extends downward to improve the bonding strength between the floor beam and the concrete inside, thereby improving the bearing strength of the floor beam and effectively preventing premature buckling of the top of the floor beam when bearing load, so that the floor beam and the ceiling beam can work fully together.

[0040] The second reinforcement member 55 is fixed to the inner side of the bottom of the first ceiling beam 3 and the second ceiling beam 4 and extends upward to improve the bonding force between the ceiling beam and the concrete inside, thereby improving the bearing strength of the ceiling beam.

[0041] Thereby, the bearing strength of the modular seismic-resistant composite beam structure can be further improved.

[0042] More preferably, in order to further improve the bonding strength between the floor beam and the ceiling beam and the concrete in the grouting cavity, the modular seismic composite beam structure further includes a third reinforcement member and a fourth reinforcement member: The third reinforcement is fixed to the top of the inner side of the bottom of the first floor beam 1 and the second floor beam 2 and extends upward to improve the bonding force between the floor beam and the concrete inside, thereby improving the bearing strength of the floor beam.

[0043] The fourth reinforcement member is fixed to the inner side of the top of the first ceiling beam 3 and the second ceiling beam 4 and extends downward to improve the bonding force between the ceiling beam and the concrete inside, thereby improving the bearing strength of the ceiling beam.

[0044] Thereby, the bearing strength of the modular seismic-resistant composite beam structure can be further improved.

[0045] Optionally, the first horizontal connecting member 51, the upper and lower connecting members 52, the second horizontal connecting member 53, the first reinforcement member 54, the second reinforcement member 55, the third reinforcement member and the fourth reinforcement member can all be components such as steel bars, bolts, hooks, etc., which can be fixed on the floor beams and ceiling beams and cast in concrete.

[0046] Preferably, the first horizontal connecting member 51 and the upper and lower connecting members 52 are both bolts, the rods of which are fixed on the corresponding ceiling beams and floor beams, and the heads of which can be cast in the concrete in the grouting cavity to increase their contact area with the concrete and increase their bonding strength with the concrete, thereby improving the bonding strength between the ceiling beams and the bottom plate beams and the concrete inside, respectively, and thereby improving the bearing strength of the modular seismic composite beam structure.

[0047] Preferably, in order to further improve the bonding strength between the floor beams and ceiling beams and the concrete in the grouting cavity, the modular seismic composite beam structure also has the following configurations: The first horizontal connecting member 51 includes a plurality of first horizontal members arranged at intervals horizontally, the upper and lower connecting members 52 include a plurality of connecting members arranged at intervals horizontally, the second horizontal connecting member includes a plurality of second horizontal members arranged at intervals vertically, and the first reinforcement member 54, the second reinforcement member 55, the third reinforcement member and the fourth reinforcement member each include a plurality of reinforcement members arranged at intervals horizontally.

[0048] Therefore, by increasing the number of the above-mentioned connecting members and reinforcing members, the bonding strength between the floor beams and ceiling beams and the concrete in the grouting cavity can be improved, thereby improving the bearing strength of the modular seismic composite beam structure and further improving the overall stability and seismic resistance of the modular building structure.

[0049] Optionally, the ends of the first horizontal connector 51, the upper and lower connectors 52, the first reinforcement 54, the second reinforcement 55, the third reinforcement and the fourth reinforcement are all welded to the corresponding floor beams and ceiling beams for easy processing. The end of the second horizontal connector 53 is welded to the column 7 for easy processing.

[0050] Furthermore, a bottom cover plate 6 is provided between the first ceiling beam 3 and the second ceiling beam 4 to close the bottom gap therebetween.

[0051] During on-site construction, after the first floor beam 1, the second floor beam 2, the first ceiling beam 3 and the second ceiling beam 4 are assembled, the bottom plate 6 is placed at the bottom gap between the first ceiling beam 3 and the second ceiling beam 4, and then concrete is poured into the grouting cavity from the top gap between the first floor beam 1 and the second floor beam 2 to prevent the concrete from overflowing from the bottom gap between the two ceiling beams, thereby facilitating engineering construction.

[0052] Optionally, the bottom cover plate 6 is a plate made of other materials such as a steel plate.

[0053] Preferably, in order to reduce costs, the modular seismic composite beam structure also has the following configuration: The first floor beam 1, the second floor beam 2, the first ceiling beam 3 and the second ceiling beam 4 are all C-shaped in cross section.

[0054] Since the first floor beam 1, the second floor beam 2, the first ceiling beam 3 and the second ceiling beam 4 can be combined into an integral modular seismic composite beam structure, it has higher bearing capacity and seismic resistance, which is superior to the traditional single-set pure concrete beam or pure steel tube beam. Compared with the traditional steel module beam with a square cross-section, the modular seismic composite beam structure adopts a beam with a C-shaped cross-section, which can save steel and reduce the cost of the beam, thereby reducing the construction cost of the modular building structure.

[0055] During on-site assembly, the openings of the first floor beam 1 and the second floor beam 2 are arranged opposite to each other, and the openings of the first ceiling beam 3 and the second ceiling beam 4 are arranged opposite to each other, and the first ceiling beam 3 and the second ceiling beam 4 are arranged correspondingly at the bottom of the first floor beam 1 and the second floor beam 2, and the gap between the first floor beam 1 and the second floor beam 2 and the gap between the first ceiling beam 3 and the second ceiling beam 4 are connected up and down to form a grouting cavity.

[0056] Specifically, when the cross-sections of the first floor beam 1, the second floor beam 2, the first ceiling beam 3 and the second ceiling beam 4 are all C-shaped, the relative side walls of the first floor beam 1 and the second floor beam 2 refer to the webs of the beams, the top refers to the upper wing plates of the beams, and the bottom refers to the lower wing plates of the beams.

[0057] Example 2

[0058] This embodiment further provides a modular building structure based on the embodiment 1. The modular building structure includes a modular earthquake-resistant composite beam structure and a column 7 .

[0059] The modular seismic composite beam structure at the connection of the upper and lower four modules is set as follows: One end of the first floor beam 1 and the second floor beam 2 in the length direction is fixed one-to-one to two horizontally adjacent columns 7 located above, and one end of the first ceiling beam 3 and the second ceiling beam 4 in the length direction is fixed one-to-one to two horizontally adjacent columns 7 located below, so that when splicing the connection points of the four upper and lower adjacent modules, the four columns 7 on the four upper and lower adjacent modules can be spliced, and the first floor beam 1, the second floor beam 2, the first ceiling beam 3 and the second ceiling beam 4 can be spliced ​​into a modular seismic composite beam structure to connect the connection points of the four upper and lower adjacent modules.

[0060] The modular seismic composite beam structure at the connection between the upper and lower modules is set as follows: One end of the first floor beam 1 and the second floor beam 2 in the length direction is fixed on the same column 7 above, and one end of the first ceiling beam 3 and the second ceiling beam 4 in the length direction is fixed on the same column 7 below, so that when splicing the connection between the upper and lower modules, the two columns 7 on the upper and lower modules can be spliced ​​up and down, and the first floor beam 1, the second floor beam 2, the first ceiling beam 3 and the second ceiling beam 4 can be spliced ​​into a modular seismic composite beam structure to connect the connection between the upper and lower modules.

[0061] Optionally, both the floor beams and the ceiling beams are welded to the columns 7 to facilitate construction.

[0062] To further explain, the following are the construction steps of modular building structures: S1. During processing, the inter-beam connecting members are arranged on the first floor beam 1, the second floor beam 2, the first ceiling beam 3 and the second ceiling beam 4.

[0063] Fix one end of the first floor beam 1 and the second floor beam 2 in the length direction to two horizontally adjacent columns 7 located above one by one; or, fix one end of the first floor beam 1 and the second floor beam 2 in the length direction to the same column 7 located above, and fix one end of the first ceiling beam 3 and the second ceiling beam 4 in the length direction to the same column 7 located below.

[0064] S2. When assembling modules on site, after the four columns 7 at the connection of four adjacent modules are spliced ​​together, or after the two columns 7 at the connection of two modules are spliced ​​together, the first floor beam 1 and the second floor beam 2 can be arranged relative to each other, and the first ceiling beam 3 and the second ceiling beam 4 can be arranged relative to each other, and the top of the first ceiling beam 3 can be attached to the bottom of the first floor beam 1, and the top of the second ceiling beam 4 can be attached to the bottom of the second floor beam 2.

[0065] S3. Pour concrete 8 into the grouting cavity formed between the first floor beam 1 and the second floor beam 2 and between the first ceiling beam 3 and the second ceiling beam 4. The inter-beam connecting parts and the concrete 8 in the grouting cavity connect the first floor beam 1 and the second floor beam 2, the first ceiling beam 3 and the second ceiling beam 4, the first floor beam 1 and the first ceiling beam 3, and the second floor beam 2 and the second ceiling beam 4 to form an overall modular seismic-resistant composite beam structure, and then form a modular building structure.

[0066] As a result, the assembly of modular building structures can be easily achieved, thereby improving construction efficiency.
