Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a staggered stacking modular structural system. Background Art

[0002] Modular building is a new type of building form, which is reflected in its construction method that is different from traditional structure. It is a structural system composed of a series of modular units assembled on site. In the existing modular structural system, the modular units are stacked vertically, and this stacking method will form a double-column, double-beam and double-plate structure. The force transmission between the modular units depends entirely on the connection nodes, which significantly increases the amount of structural steel compared with the traditional structure. The staggered stacking modular structural system can form a beam-column lateral force resistance system similar to the traditional frame structure by staggering the modules. In the traditional frame structure, the connection between columns and columns and between beams and columns is generally rigid and equally strong, and the structural design is simple. The stiffness and bearing capacity of the staggered stacking connection nodes are the key. At present, the bearing capacity of the connection nodes cannot reach the bearing capacity required by the connected modular columns, which will increase the difficulty of staggered stacking design and limit its scope of application.

[0025] See also Figures 1 to 3As shown, the utility model relates to a staggered stacked modular structural system 100. The staggered stacked modular structural system 100 is mainly composed of a plurality of rectangular module units 10 that are staggered and stacked to form a multi-layer rectangular main structure. The rectangular module unit 10 includes a crossbeam 2, a column 1 and a connector 3. The connector 3 includes a connecting plate 31, a C-shaped plug-in block 32 connected to the connecting plate 31, and a C-shaped plug-in tube 33. The C-shaped plug-in block 32 can be plugged into the C-shaped plug-in tube 33; both ends of the column 1 are respectively welded to the connecting plate 31 of the connector 3, and both ends of the crossbeam 2 are respectively welded to the C-shaped plug-in tube 33 of the connector 3. After the connectors 3 of two adjacent rectangular module units 10 are plugged in, a grouting space is formed, and the two rectangular module units 10 are connected by grouting.

[0026] Four cross beams 2 are welded through four connectors 3 to form a frame structure, and two frame structures are welded through four uprights 1 to form a rectangular module unit 10 supported by corner columns.

[0027] The cross section of the C-shaped plug-in block 32 of the two connected connectors 3 corresponds to the connected column 1, which is conducive to the direct transfer of load of the column 1. The cross section of the C-shaped plug-in tube 33 of the two connected connectors 3 corresponds to the connecting plate 31. Figure 4 and Figure 5 As shown, the C-shaped plug-in barrel 33 has a first side wall 331 and a second side wall 332. The first side wall 331 is connected to one side of the connecting plate 31, and the second side wall 332 is connected to the other side of the connecting plate 31. The connecting plate 31 is a square plate body, and all the side lengths are the same. The length of the first side wall 331 is equal to the side length of the connecting plate 31, and the length of the second side wall 332 is less than half of the side length of the connecting plate 31. The crossbeam 2 includes a first crossbeam 2a and a second crossbeam 2b. The end of the first crossbeam 2a is connected to the first side wall 331 of the C-shaped plug-in barrel 33 of the connecting member 3, and the end of the second crossbeam 2b is connected to the second side wall 332 of the C-shaped plug-in barrel 33 of the connecting member 3. Two first crossbeams 2a and two second crossbeams 2b are welded through four connecting members 3 to form a frame structure. Since the thickness of the second beam 2b is approximately the same as that of the first beam 2a cut in half, after the rectangular module units 10 are staggered and stacked, the second beams 2b of two adjacent rectangular module units 10 are arranged side by side, which is approximately equal to the thickness of the first beam 2a, thereby eliminating the situation of double columns, double beams, and double plates after the module units are stacked from top to bottom, and avoiding the problem of large amount of steel used in modular buildings.

[0028] In order to improve the node strength at the corner of the C-shaped plug-in tube 33, a reinforcing plate 39 is provided at the corner of the C-shaped plug-in tube 33, and the top surface of the reinforcing plate 39 is on the same plane as the top surface of the C-shaped plug-in tube 33, so as to facilitate the transfer of the load transmitted by the C-shaped plug-in tube 33. The connector 3 is provided with a grouting hole 37 and an overflow hole 38 in the vertical direction, and the grouting hole 37 and the overflow hole 38 are connected to the grouting space, so as to facilitate the injection of slurry into the grouting space. The grouting hole 37 is connected to the slurry inlet pipe, and the overflow hole 38 is connected to the slurry outlet pipe. The grouting method is to feed slurry through the lower slurry inlet pipe and discharge slurry through the upper slurry outlet pipe. The discharge of slurry from the upper slurry outlet pipe indicates that it is full. Since the two connectors 3 are symmetrically vertically plugged, the through hole arranged at the top is the overflow hole 38, and the through hole arranged at the bottom is the grouting hole 37, based on the vertical direction. The overflow hole 38 and the grouting hole 37 can be uniformly arranged on the side wall of the C-shaped plug-in tube 33 , or one of them can be arranged on the connecting plate 31 .

[0029] like Figure 6 As shown, the outer wall of the C-shaped plug-in block 32 has a plurality of first bolts 34 extending horizontally outward, and the plurality of first bolts 34 are arranged in a plurality of vertical rows; the inner wall of the C-shaped plug-in tube 33 has a plurality of second bolts 35 extending horizontally inward, and the plurality of second bolts 35 are arranged in a plurality of vertical rows; after the two connectors 3 are plugged in, the vertical rows composed of the first bolts 34 and the vertical rows composed of the second bolts 35 are staggered with each other in the horizontal direction. The first bolts 34 and the second bolts 35 have the same structure, both including a circular plate and a connecting rod fixedly connected to one side of the circular plate. After the two connectors 3 are plugged in, a grouting space is formed, and slurry is injected into the grouting space. After the slurry solidifies, the two connectors 3 are tightly connected. Since the grouting space is provided with the first bolts 34 and the second bolts 35, the reliability of the connection between the two connectors 3 is improved.

[0030] The connecting member 3 further includes stiffening ribs 36, which are welded to the connecting plate 31 and the column 1 respectively. A plurality of stiffening ribs 36 of triangular structure are arranged around the edge of the connecting plate 31, so that the column 1 can still maintain the overall stability well when subjected to torque.

[0031] The opening of the C-shaped plug-in block 32 and the opening of the C-shaped plug-in tube 33 are symmetrically arranged facing each other; when the two connectors 3 are plugged in, a buffer gap is formed between the openings of the C-shaped plug-in tubes 33 of the two connected connectors 3, which can buffer the vertical load applied by the column 1 on the connector 3, carry a larger vertical load, and ensure the stable bearing capacity of the staggered stacked modular structural system 100.

[0032] In this embodiment, the connecting plate 31 is a square plate body, and the connecting plate 31 is evenly divided into two areas. The number of the C-shaped plug-in block 32 and the number of the C-shaped plug-in tube 33 are respectively one, and they are separately arranged corresponding to one area.

[0033] Of course, the connecting plate 31 can also be divided into three or four areas, but the total number of C-shaped plug blocks 32 and C-shaped plug barrels 33 is no more than five. The connecting plate 31 is evenly divided into four areas, and the number of C-shaped plug blocks 32 and C-shaped plug barrels 33 is two, and each corresponds to a separate area; the C-shaped plug blocks 32 and C-shaped plug barrels 33 are symmetrically arranged side by side or staggered, and such a design makes the crossbeam 2 a double beam structure.

[0034] The connecting plate 31 can also be divided into three areas. The three areas can be divided equally, or one of the areas can be half of the connecting plate 31, and two of the areas can be quarters of the connecting plate 31. One C-shaped plug-in block 32 and two C-shaped plug-in tubes 33 correspond to one area setting separately, or two C-shaped plug-in blocks 32 and one C-shaped plug-in tube 33 correspond to one area setting separately.

[0035] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
