Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and particularly relates to a self-locking integral assembled building structure connection system. Background Art

[0002] Prefabricated buildings have become an important direction for realizing green buildings and industrialization due to their short construction period and small environmental impact. Among them, modular integrated construction (MiC) is the prefabricated building with the highest assembly rate and the highest degree of industrialization. In existing prefabricated concrete modular buildings, some parts still need to be cast in situ on site, and the advantages of rapid construction of modular integrated construction cannot be fully utilized. At the same time, in modular integrated construction with a frame structure as the load-bearing part, the upper and lower frame modules are generally only connected by corner columns. Once the connection at the corner column is damaged, the structure is prone to failure and cause overall collapse, and the overall performance of the existing assembled building structure is poor and the seismic performance is low. Summary of the Invention

[0003] (I) Technical Problems to be Solved

[0004] In order to solve the above problems of the existing technology, the present invention provides a self-locking integral assembled building structure connection system to solve the problems of slow construction, poor overall structure performance, and low seismic performance in the background art.

[0005] (II) Technical Solutions

[0006] In order to achieve the above object, the main technical solutions adopted by the present invention are as follows:

[0007] A self-locking integral assembled building structure connection system includes: multiple layers of frame modules, and each layer of frame modules includes a plurality of first frame module units or a plurality of second frame module units;

[0008] The adjacent two layers of the frame modules are different frame module units;

[0009] Both the first frame module unit and the second frame module unit include: an upper beam frame and a lower beam frame;

[0010] The corresponding corners of the upper beam frame and the lower beam frame are fixedly connected by frame columns to form a cuboid frame structure;

[0011] A plurality of tenons and a plurality of mortises are arranged on the surfaces of the upper beam frame and the lower beam frame;

[0012] Between adjacent first frame module units, between adjacent second frame module units, and between adjacent first frame module units and second frame module units, tenon and mortise structures can be formed through connection of the tenons and the mortises;

[0013] A first support frame is further disposed between the upper beam frame and the lower beam frame of the first frame module unit;

[0014] A second support frame is further disposed between the upper beam frame and the lower beam frame of the second frame module unit.

[0015] In the self-locking integral assembled composite building structure connection system of the present invention, each frame module unit includes two upper and lower rectangular beam frames, each beam frame includes 4 cross beams fixedly connected, the upper and lower beam frames are fixedly connected by 4 frame columns, a plurality of tenons and mortises are uniformly arranged on the surface of the cross beam, and an anti-buckling energy dissipation support frame is further disposed between the upper beam frame and the lower beam frame of the frame module unit. Adjacent two frame module units are connected through the tenons and mortises on the surface of the cross beam. The tenon and mortise structure can make the connection between adjacent modules better, which is equivalent to playing a "self-locking" role and improving the integrity of the structure. When a local structure is damaged, it can ensure that the overall structure does not collapse. The anti-buckling energy dissipation support frame can play a role during an earthquake and improve the seismic performance of the structure system.

[0026] A plurality of eighth tenons are arranged on the outer side surface of the eighth cross beam, and a plurality of eighth mortise grooves are formed on the lower side surface of the eighth cross beam.

[0027] In the self-locking integral assembled synthetic building structure connection system of the present invention, during assembly, the tenons on the outer side surfaces of the first cross beam and the second cross beam can cooperate with the mortise grooves on the outer side surfaces of the third cross beam and the fourth cross beam of the adjacent frame module units on the same horizontal plane, and the mortise grooves on the outer side surfaces of the third cross beam and the fourth cross beam can cooperate with the tenons on the outer side surfaces of the first cross beam and the second cross beam of the adjacent frame module units on the same horizontal plane;

[0028] The mortise grooves on the upper side surfaces of the first cross beam and the second cross beam can cooperate with the tenons on the lower side surfaces of the fifth cross beam and the sixth cross beam of the adjacent frame module units on the same vertical plane, and the tenons on the upper side surfaces of the third cross beam and the fourth cross beam can cooperate with the mortise grooves on the lower side surfaces of the seventh cross beam and the eighth cross beam of the adjacent frame module units on the same vertical plane;

[0029] The assembly methods of the fifth cross beam, the sixth cross beam, the seventh cross beam and the eighth cross beam of the lower beam frame are similar to those of the cross beams of the upper beam frame, and the whole forms a mortise and tenon structure, which plays a role of mutual restriction and ensures the overall stability of the structure.

[0030] Preferably, the first support frame is arranged between two corresponding cross beams in the upper beam frame and the lower beam frame of the first frame module unit; the second support frame is arranged between two corresponding cross beams in the upper beam frame and the lower beam frame of the second frame module unit.

On the premise that the mortise and tenon structure improves the structural integrity, the buckling-resistant energy dissipation support frame can play a role during an earthquake, improve the energy dissipation effect on seismic energy, and further enhance the seismic performance of the overall structure.

[0035] (III) Beneficial effects

[0036] The beneficial effects of the present invention are as follows:

[0037] The self-locking integral assembled synthetic building structure connection system of the present invention is composed of a cross beam frame with mortise and tenon connection members, frame columns, and a buckling-resistant energy dissipation support frame. The frame beam columns are the main load-bearing structures of the module. The beam-column connection nodes ensure the effective connection of the upper and lower modules. When the module is damaged, the mortise and tenon structure on the cross beam can enable better connection of adjacent modules. After the modules are connected, they restrict each other. When a part of the structure is damaged, the mortise and tenon structure can play a "self-locking" role to ensure that the overall structure does not collapse; its structural integrity can ensure that the buckling-resistant energy dissipation support frame plays a role during an earthquake and improve the seismic performance of the structural system; the mortise and tenon connection method is simple in construction and can also improve the construction speed of the modular assembled synthetic building and save construction time.

[0051] For better explaining the present invention for easy understanding, the present invention will be described in detail below in conjunction with the accompanying drawings through specific implementation modes. Among them, the orientation such as "outer side" mentioned in this article is Figure 1 oriented as a reference. Specifically, the inside of the frame module unit is defined as the "inner side", and the outside of the frame module unit is defined as the "outer side".

[0052] Embodiment

[0053] As Figure 1 、 Figure 2 shown, the self-locking integral assembled synthetic building structure connection system of the present invention includes: multiple layers of frame module units. Each layer of frame module includes multiple first frame module units or multiple second frame module units. The single-layer frame module adopts the same frame module unit, and adjacent two layers of frame module adopt different frame module units. Both the first frame module unit and the second frame module unit include: an upper beam frame 1 and a lower beam frame 2. Both the upper beam frame 1 and the lower beam frame 2 are rectangular beam frames. The upper beam frame 1 includes fixedly connected first crossbeam 11, second crossbeam 12, third crossbeam 13 and fourth crossbeam 14. The lower beam frame 2 includes fixedly connected fifth crossbeam 21, sixth crossbeam 22, seventh crossbeam 23 and eighth crossbeam 24. The upper beam frame 1 and the lower beam frame 2 are arranged parallel to each other correspondingly. Specifically, the first crossbeam 11 corresponds to the fifth crossbeam 21, the second crossbeam 12 corresponds to the sixth crossbeam 22, the third crossbeam 13 corresponds to the seventh crossbeam 23, and the fourth crossbeam 14 corresponds to the eighth crossbeam 24. At the corresponding corners of the upper beam frame 1 and the lower beam frame 2, they are fixedly connected by 4 frame columns 3 to form a cuboid frame structure. On the surfaces of the upper beam frame 1 and the lower beam frame 2, a plurality of tenons and a plurality of mortises are evenly arranged.

[0054] Between adjacent first frame module units, between adjacent second frame module units, and between adjacent first and second frame module units, tenon joints and mortises provided on the surface of the crossbeams can be used for connection to form a tenon and mortise structure. A first support frame 4 is further provided between the upper beam frame 1 and the lower beam frame 2 of the first frame module unit, and a second support frame is further provided between the upper beam frame 1 and the lower beam frame 2 of the second frame module unit. Both the first support frame 4 and the second support frame are buckling-resistant energy-dissipating support frames, and the first support frame 4 and the second support frame are arranged in an X shape.

[0055] Specifically, a plurality of first tenons 1101 are uniformly provided on the outer side surface of the first crossbeam 11, a plurality of first mortises 1102 are uniformly formed on the upper side surface of the first crossbeam 11, a plurality of second tenons 1201 are uniformly provided on the outer side surface of the second crossbeam 12, a plurality of second mortises 1202 are uniformly formed on the upper side surface of the second crossbeam 12, a plurality of third mortises 1301 are uniformly formed on the outer side surface of the third crossbeam 13, a plurality of third tenons 1302 are uniformly provided on the upper side surface of the third crossbeam 13, a plurality of fourth mortises 1401 are uniformly formed on the outer side surface of the fourth crossbeam 14, and a plurality of fourth tenons 1402 are uniformly provided on the upper side surface of the fourth crossbeam 14.

[0056] Similarly, a plurality of fifth mortises are uniformly formed on the outer side surface of the fifth crossbeam 21, a plurality of fifth tenons are uniformly provided on the lower side surface of the fifth crossbeam 21, a plurality of sixth mortises are uniformly formed on the outer side surface of the sixth crossbeam 22, a plurality of sixth tenons are uniformly provided on the lower side surface of the sixth crossbeam 22, a plurality of seventh tenons are uniformly provided on the outer side surface of the seventh crossbeam 23, a plurality of seventh mortises are uniformly formed on the lower side surface of the seventh crossbeam 23, a plurality of eighth tenons are uniformly provided on the outer side surface of the eighth crossbeam 24, and a plurality of eighth mortises are uniformly formed on the lower side surface of the eighth crossbeam 24.

[0057] A plurality of tenons and mortises are uniformly provided on the outer surfaces of the first frame module unit and the second frame module unit of the present invention. Between adjacent first frame module units on the same layer, between adjacent second frame module units, and between the first frame module unit and the second frame module unit on adjacent layers, the above-mentioned tenons and mortises can be mutually matched and connected to form a tenon and mortise structure, so that the frame module has better integrity. When a local component of the frame module fails accidentally, the tenon and mortise structure can be mutually "self-locked" and restricted to ensure that the whole frame module will not collapse.

[0058] The first support frame 4 of the present invention is arranged between two corresponding cross beams in the upper beam frame 1 and the lower beam frame 2 of the first frame module unit, and the second support frame is arranged between two corresponding cross beams in the upper beam frame 1 and the lower beam frame 2 of the second frame module unit; a first support frame 4 and a second support frame are arranged in each group of corresponding upper and lower cross beams of the upper beam frame 1 and the lower beam frame 2 of the first frame module unit and the second frame module unit;

[0059] The first support frame 4 is in a positive "V" shape, and the second support frame is in an inverted "V" shape; alternatively, the first support frame 4 is in an inverted "V" shape, and the second support frame is in a positive "V" shape, that is, the first support frame 4 and the second support frame on the same side of adjacent first frame module units and second frame module units located in the same vertical plane are arranged in mirror symmetry;

[0060] Adjacent two frame module units adopt support frames in different forms, and the first support frame 4 and the second support frame arranged adjacent up and down are arranged in an X shape, improving the energy dissipation effect on seismic energy, and further enhancing the overall seismic performance of the structure.

[0061] In a preferred implementation manner of the support frame of the present invention, the first support frame 4 is only arranged between two corresponding groups of cross beams extending along the length direction of the first frame module unit in the first frame module unit, and the second support frame is only arranged between two corresponding groups of cross beams extending along the length direction of the second frame module unit in the second frame module unit.

[0062] In the above setting method, on the premise of meeting the support force, the first frame module unit can save two first support frames 4, and the second frame module unit can save two second support frames, saving certain construction materials and reducing costs.

[0063] Both the first support frame 4 and the second support frame of the present invention include a first support rod and a second support rod, and the first support rod and the second support rod have the same structure. Specifically, as Figure 1 shown, the first support frame 4 is arranged between the second cross beam 12 and the sixth cross beam 22 and between the fourth cross beam 14 and the eighth cross beam 24 in the first frame module unit;

[0064] Taking the first support frame 4 between the second cross beam 12 and the sixth cross beam 22 as an example, one end of the first support rod is hinged to the middle of the second cross beam 12, the other end of the first support rod is hinged to the beam-column connection part of the sixth cross beam 22 and the frame column 3, one end of the second support rod is hinged to the middle of the second cross beam 12, and the other end of the second cross beam is hinged to the beam-column connection part of the other end of the sixth cross beam 22 and the frame column 3. The first support rod and the second support rod form an inverted "V" shaped first support frame 4;

[0065] Alternatively, one end of the first support rod is hinged to the middle of the sixth cross beam 22, and the other end of the first support rod is hinged to the beam-column connection of the second cross beam 12 and the frame column 3. One end of the second support rod is hinged to the middle of the sixth cross beam 22, and the other end of the second cross beam is hinged to the beam-column connection of the other end of the second cross beam 12 and the frame column 3. The first support rod and the second support rod form a first support frame 4 in a positive "V" shape;

[0066] The arrangement of the first support rod and the second support rod of the second support frame in the second frame module unit is opposite to the arrangement of the first support frame 4. When the first support frame 4 is in an inverted "V" shape, the second support frame is in a positive "V" shape. When the first support frame 4 is in a positive "V" shape, the second support frame is in an inverted "V" shape.

[0067] In a preferred embodiment of the present invention, the length of the second cross beam 12 is twice that of the first cross beam 11, the length of the fourth cross beam 14 is twice that of the third cross beam 13, the length of the sixth cross beam 22 is twice that of the fifth cross beam 21, and the length of the eighth cross beam 24 is twice that of the seventh cross beam 23.

[0068] As described above, the length of the second cross beam 12 of the upper beam frame 1 is twice that of the first cross beam 11, the length of the fourth cross beam 14 is twice that of the third cross beam 13, the length of the sixth cross beam 22 of the lower beam frame 2 is twice that of the fifth cross beam 21, and the length of the eighth cross beam 24 is twice that of the seventh cross beam 23. This design can form a 90-degree angle between the first support rod and the second support rod. The right-angle design can ensure the stability of the supporting capacity of the first support frame 4 and the second support frame, improve its seismic performance, and play a better role during an earthquake.

[0069] As Figure 2 shown, multiple frame module units of the present invention are assembled together to form an overall structure. During assembly, the support frames of adjacent two frame module units in the same vertical plane adopt different arrangement methods. Specifically, the first support frame 4 of the first frame module unit is in an inverted "V" shape, the second support frame of the upper second frame module unit is in a positive "V" shape, the second support frame of the lower second frame module unit is also in a positive "V" shape, and the first support frame 4 of the first frame module unit and the second support frame of the second frame module unit are arranged in an X shape.

[0070] The integrity of the structure of the present invention can ensure that the first support frame 4 and the second support frame play a role during an earthquake. The first support frame 4 and the second support frame arranged in an X shape can improve the energy dissipation effect on seismic energy, transfer and consume the energy input by the earthquake, thereby reducing the vibration and deformation of the frame structure system, avoiding or delaying its damage or destruction, and improving the seismic performance of the structure system.

[0071] As Figure 3As shown in the self-locking integral assembly synthetic building structure connection system of the present invention, when assembling adjacent frame module units, the tenons and grooves on the surfaces of the adjacent frame module unit beams are matched to assemble together. Figure 2 Taking the connection A in the middle as an example, the first beam 11, the third beam 13, the seventh beam 23 and the fifth beam 21 of the four adjacent frame module units are assembled by cooperation with each other. Specifically, the first tenon 1101 on the outer side of the first beam 11 cooperates with the third tenon groove 1301 on the outer side of the third beam 13, the third tenon 1302 on the upper side of the third beam 13 cooperates with the seventh tenon groove on the lower side of the seventh beam 23, the seventh tenon on the outer side of the seventh beam 23 cooperates with the fifth tenon groove on the outer side of the fifth beam 21, and the fifth tenon on the lower side of the fifth beam 21 cooperates with the first tenon groove 1102 on the upper side of the first beam 11 to form a connecting lock.

[0072] The self-locking integrally assembled building structure connection system of the present invention adopts the following method to connect the beams of adjacent frame module units to each beam of each frame module unit located inside the structure system, except for a layer of frame module units located on the outer periphery of the entire system. Figure 2 The connection method of the connection point A in the middle is connected together; the "mortise and tenon connection" method between adjacent frame module units of the present invention is simple to construct. Compared with the existing prefabricated concrete modular buildings that still need to be cast on site, it can give play to the advantages of rapid construction of modular assembled synthetic buildings, improve the construction speed of modular assembled synthetic buildings, save construction time, and improve economic benefits.

[0073] The technical principles of the present invention are described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the present invention and cannot be interpreted in any way as limiting the scope of protection of the present invention. Based on the explanations here, those skilled in the art can associate other specific implementations of the present invention without creative work, and these methods will fall within the scope of protection of the present invention.
