It has strong competitiveness and has been widely used. Reinforced concrete modular buildings are a type of modular buildings, and their application scale in China has shown an increasing trend in recent years. Due to the three-dimensional prefabrication characteristics of concrete modular units, when adjacent modules are stacked and connected on site, the floor and wall parts will present a double-plate double-wall structure, that is, the top plate of the lower module unit and the bottom plate of the upper module unit form a double-plate structure, and the wall between adjacent modules forms a double-wall structure. In addition, the current construction technology of reinforced concrete modules generally makes the top plate structure of the lower module into a reinforced truss floor slab. It is necessary to tie steel bars and pour concrete on site to form a structural floor slab. After the concrete is hardened and formed, it is connected to the bottom plate structure of the upper module to form a double-plate structure. The workload of on-site steel bar tying is large, the amount of wet work is large, and the labor demand is large.

[0033] Example 1
[0034] A specific embodiment of the present invention, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a composite component connection structure is disclosed, including a first reinforced concrete precast component 1, a second reinforced concrete precast component 2 and a cast-in-place concrete layer 3, the cast-in-place concrete layer 3 is arranged between the first reinforced concrete precast component 1 and the second reinforced concrete precast component 2, the first reinforced concrete precast component 1 and the second reinforced concrete precast component 2 are both precast beams or the first reinforced concrete precast component 1 and the second reinforced concrete precast component 2 are both precast walls.
[0035] When the first reinforced concrete prefabricated component 1 and the second reinforced concrete prefabricated component 2 are both prefabricated beams and slabs, Figure 1 As shown, the first reinforced concrete prefabricated component 1 is arranged above the second reinforced concrete prefabricated component 2, and the two are arranged horizontally. Figure 1 and Figure 2 As shown, the first reinforced concrete prefabricated component 1 includes a first prefabricated concrete beam 11 and a first prefabricated concrete slab 12 , and the first prefabricated concrete beam 11 is arranged around the first prefabricated concrete slab 12 .
[0036] Accordingly, if Figure 1 and Figure 2As shown, the second reinforced concrete prefabricated component 2 includes a second prefabricated concrete beam 21 and a second prefabricated concrete slab 22 , and the second prefabricated concrete beam 21 is arranged around the second prefabricated concrete slab 22 .
[0037] Preferably, the first prefabricated reinforced concrete component 1 and the second prefabricated reinforced concrete component 2 are both integrally prefabricated in a factory.
[0038] Considering the connection between the first reinforced concrete prefabricated component 1 and the second reinforced concrete prefabricated component 2, as shown in FIG. Figure 1 and Figure 2 As shown, the cross section of the first precast concrete beam 11 is set to be T-shaped, that is, the first precast concrete beam 11 is a T-shaped beam, and the cross section of the second precast concrete beam 21 is set to be rectangular. A first U-shaped groove 211 is provided on the upper surface (i.e., the top) of the second precast concrete beam 21, and the lower end of the first precast concrete beam 11 is provided in the first U-shaped groove 211. The opening width of the first U-shaped groove 211 is not less than the sum of the cross-sectional width of the lower end of the first precast concrete beam 11 and 2 times the installation allowable deviation. It should be noted that the cross section refers to the cross section perpendicular to the length direction of the precast concrete beam.
[0039] In this embodiment, the first precast concrete beam 11 is configured as a T-shaped beam, and a first U-shaped groove 211 is provided on the upper portion of the second precast concrete beam 21. The lower end of the T-shaped beam is inserted into the first U-shaped groove 211 to achieve a preliminary connection between the first precast concrete beam 11 and the second precast concrete beam 21, which is convenient and quick. At the same time, the opening width of the first U-shaped groove 211 is not less than the sum of the cross-sectional width of the lower end of the first precast concrete beam 11 and 2 times the allowable installation deviation, which can reserve sufficient margin for assembly and the connection between the T-shaped beam and the first U-shaped groove 211.
[0040] It should be noted that the cross section of the first precast concrete beam 11 is not limited to a T-shape, but may also be a dovetail shape or other shapes that are easy to assemble. Accordingly, a dovetail groove is provided on the top of the second precast concrete beam 21 .
[0041] In order to enhance the structural strength of the first precast concrete panel 12 and the connection strength between the first precast concrete panel 12 and the second precast concrete panel 22, as shown in FIG. Figure 1 and Figure 2 As shown, the first precast concrete panel 12 is provided with first transverse and longitudinal steel bars 121 and a first steel bar truss 122, the first steel bar truss 122 is overlapped with the first transverse and longitudinal steel bars 121, and the first steel bar truss 122 extends out of the lower bottom surface of the first precast concrete panel 12. A plurality of first steel bar trusses 122 are provided, and the plurality of first steel bar trusses 122 are evenly distributed along the length direction of the first precast concrete panel 12. It should be noted that the first transverse and longitudinal steel bars 121 are steel meshes formed by transversely arranged steel bars and longitudinally arranged steel bars arranged in the first steel bar truss 122.
[0042] In this embodiment, by providing a steel mesh formed by longitudinal and transverse steel bars, i.e., first transverse and longitudinal steel bars 121, and a first steel bar truss 122 overlapped with the first transverse and longitudinal steel bars 121 in the first precast concrete slab 12, the structural strength of the first precast concrete slab 12 is improved to meet its functional requirements as a beam and slab.
[0043] It can be understood that in order to enhance the structural strength of the second precast concrete panel 22, as shown in FIG. Figure 1 and Figure 2 As shown, second transverse and longitudinal reinforcement bars 221 are provided in the second precast concrete slab 22 .
[0044] Furthermore, a second steel bar truss (not shown in the figure) is provided in the second precast concrete panel 22, and a plurality of second steel bar trusses are provided, and the plurality of second steel bar trusses are arranged along the length direction of the second precast concrete panel 22, and the second steel bar trusses overlap the second transverse and longitudinal steel bars 221. The upper end of the second steel bar truss extends out of the top of the second precast concrete panel 22, and the second steel bar truss is staggered with the first steel bar truss 122 to avoid interference between the two.
[0045] In this embodiment, a second steel bar truss is provided in the second precast concrete panel 22 , and the second steel bar truss is overlapped with the second transverse and longitudinal steel bars 221 , thereby further improving the structural strength of the second precast concrete panel 22 .
[0046] In order to form a stable connection between the first precast concrete panel 12 and the second precast concrete panel 22, as shown in FIG. Figure 1 and Figure 2 As shown, the upper surface of the second precast concrete panel 22 is provided with first bosses 222 and first grooves 223 at intervals (staggered), the first steel bar truss 122 is vertically opposite to the first groove 223, and the second steel bar truss protrudes from the first groove 223 but is not higher than the top of the first boss 222. When the first precast concrete panel 12 is arranged on the second precast concrete panel 22, the lower end of the first steel bar truss 122 is located in the first groove 223 but does not contact the second steel bar truss.
[0047] The cast-in-place concrete layer 3 is non-shrinkage or slightly expansive concrete.
[0048] In this embodiment, a cast-in-place concrete layer 3 is arranged between the first reinforced concrete precast component 1 and the second reinforced concrete precast component 2. After concrete is poured into the first U-shaped groove 211 and the first groove 223, the first reinforced concrete precast component 1 is arranged above the second reinforced concrete precast component 2 before the concrete is initially set, and the lower end of the first concrete precast beam 11 is inserted into the first U-shaped groove 211, and the lower end of the first steel bar truss 122 is inserted into the first groove 223. When the cast-in-place concrete is solidified, the first reinforced concrete precast component 1 and the second reinforced concrete precast component 2 are stably connected. The first reinforced concrete precast component 1 and the second reinforced concrete precast component 2 are effectively combined and subjected to force together, which effectively improves the structural bearing capacity. At the same time, the double-beam and double-slab structure is avoided, and the thickness of the floor slab (bottom slab) is reduced, which is more economical and easy to operate. No steel bar binding operation is required at the operation site, which greatly improves the connection speed and efficiency at the construction site.
[0049] When the first reinforced concrete prefabricated component 1 and the second reinforced concrete prefabricated component 2 are both prefabricated walls, Figure 3 As shown, the first reinforced concrete prefabricated component 1 and the second reinforced concrete prefabricated component 2 are arranged vertically. Figure 3 and Figure 4 As shown, the first reinforced concrete precast component 1 includes a first precast concrete wall panel 13 and a first precast concrete column 14, and the first precast concrete column 14 is arranged around the first precast concrete wall panel 13. The second reinforced concrete precast component 2 includes a second precast concrete wall panel 23 and a second precast concrete column 24, and the second precast concrete column 24 is arranged around the second precast concrete wall panel 23.
[0050] Understandably, if Figure 3 and Figure 4 As shown, the first prefabricated concrete wall panel 13 is provided with third transverse and longitudinal steel bars 131 and third steel bar trusses 132, the third steel bar trusses 132 are overlapped with the third transverse and longitudinal steel bars 131, and the third steel bar trusses 132 protrude from the side of the first prefabricated concrete wall panel 13. The third steel bar trusses 132 are evenly distributed along the length of the first prefabricated concrete wall panel 13.
[0051] like Figure 3 and Figure 4 As shown, the second precast concrete wall panel 23 is provided with fourth transverse and longitudinal steel bars 231, and the side surface of the second precast concrete wall panel 23 adjacent to the first precast concrete wall panel 13 is staggered with second bosses 232 and second grooves 233, and the portion of the third steel bar truss 132 protruding from the first precast concrete wall panel 13 corresponds to the second groove 233. The surface of the second precast concrete column 24 adjacent to the first precast concrete column 14 is provided with a second U-shaped groove 241, and the second U-shaped groove 241 is connected to the first precast concrete column 14 of the T-shaped structure.
[0052] Furthermore, a fourth steel truss (not shown) is provided in the second prefabricated concrete wall panel 23 , and the fourth steel truss is arranged along the length of the second prefabricated concrete wall panel 23 , and the protruding portion of the fourth steel truss is located in the second groove 233 and does not exceed the second boss 232 .
[0053] It should be noted that the first precast concrete wall panel 13 has the same structure as the first precast concrete panel 12 , the second precast concrete wall panel 23 has the same structure as the second precast concrete panel 22 , the first precast concrete column 14 has the same structure as the first precast concrete beam 11 , and the second precast concrete column 24 has the same structure as the second precast concrete beam 21 .
[0054] In this embodiment, the first precast concrete wall panel 13 and the second precast concrete wall panel 23 are connected by the third steel truss 132 corresponding to the second groove 233 and poured with concrete, and the first precast concrete column 14 and the second precast concrete column 24 are connected by the second U-shaped groove 241 and the T-shaped column and poured with concrete, so that they are effectively combined to bear the force together, which effectively improves the bearing capacity of the structure. At the same time, the double wall structure is avoided, and the wall thickness is reduced, which is more economical and easy to operate. There is no need for steel bar binding operations at the work site, which greatly improves the connection speed and efficiency at the construction site.
[0055] like Figure 5 As shown, as a preferred alternative, the third steel truss 132 is not provided in the first precast concrete wall panel 13, but is replaced by a third boss 133, the third boss 133 cooperates with the second groove 233 of the second precast concrete wall panel 23, the first precast concrete column 14 is provided with a third U-shaped groove 141, the third U-shaped groove 141 is opposite to the second U-shaped groove 241, and a steel cage 4 is provided in the space formed by the two, and concrete is poured in the gap between the first precast concrete wall panel 13 and the second precast concrete wall panel 14. Since the first precast concrete wall panel 13 and the second precast concrete wall panel 14 are plugged in by the boss and the groove, the thickness of the wall panel formed by the connection between the two can be reduced. At the same time, the docking mode of the third U-shaped groove 141 and the second U-shaped groove 241 is more convenient for hoisting operation, and can reduce the interference between components during the hoisting process.
[0056] like Figure 6As shown, as another preferred alternative, the second precast concrete wall panel 23 is not provided with the second boss 232, but is replaced by a fourth steel truss 234, the fourth steel truss 234 and the third steel truss 132 are staggered, the first precast concrete column 14 is provided with a third U-shaped groove 141, the third U-shaped groove 141 is opposite to the second U-shaped groove 241, and a steel cage 4 is arranged in a space formed by the two, and concrete is poured into the third U-shaped groove 141 and the second U-shaped groove 241 in the gap between the first precast concrete wall panel 13 and the second precast concrete wall panel 14. Since the thickness of the first precast concrete wall panel 13 and the second precast concrete wall panel 14 is reduced, the two can also achieve the purpose of reducing the thickness of the wall panel after being connected by a cast-in-place concrete layer 3, and at the same time, it does not affect the use, and the third steel truss 132, the fourth steel truss 234 and the steel cage 4 can increase the structural strength of the component.

[0058] Another specific embodiment of the present invention, as Figure 1-Figure 6 As shown, a reinforced concrete modular building is disclosed, comprising a plurality of reinforced concrete modular units, wherein the reinforced concrete modular unit comprises the first precast concrete beam 11, the first precast concrete slab 12, the first precast concrete wall panel 13, the first precast concrete column 14, the second precast concrete beam 21, the second precast concrete slab 22, the second precast concrete wall panel 23 and the second precast concrete column 24 of Example 1, wherein the first precast concrete slab 12 and the first precast concrete beam 11 are connected as a bottom panel, the second precast concrete slab 22 and the second precast concrete beam 21 are connected as a top panel, the first precast concrete wall panel 13 and the first precast concrete column 14 are connected as a left wall panel and a front wall panel, and the second precast concrete wall panel 23 and the second precast concrete column 24 are connected as a right wall panel and a rear wall panel. The top panel, the bottom panel, the left wall panel, the right wall panel, the front wall panel and the rear wall panel are surrounded to form a reinforced concrete modular unit.
[0059] When the reinforced concrete module units are provided with multiple layers, the upper and lower adjacent reinforced concrete module units are inserted into the first U-shaped groove 211 through the T-beam, and the lower end of the first steel truss 122 is inserted into the first groove 223. When the cast-in-place concrete provided in the first groove 223 and the first U-shaped groove 211 solidifies, the upper and lower layers of reinforced concrete module units are connected together, so that they are effectively combined and subjected to force together, which effectively improves the structural bearing capacity. At the same time, the double-beam and double-slab structure is avoided, and the thickness of the floor slab (bottom slab) is reduced, which is more economical and the connection method is easy to operate. No steel bar binding operation is required at the work site, which greatly improves the connection speed and efficiency at the construction site.
[0060] When multiple reinforced concrete module units are arranged on the left and right and / or front and back, the reinforced concrete module units arranged on the left and right are taken as an example below. The adjacent reinforced concrete module units on the left and right are connected by the third steel truss 132 corresponding to the second groove 233 and poured with concrete, and the first precast concrete column 14 and the second precast concrete column 24 are connected by the second U-shaped groove 241 and the T-shaped column and poured with concrete, so that they are effectively combined to bear the force together, which effectively improves the structural bearing capacity. At the same time, the double wall structure is avoided, the wall thickness is reduced, it is more economical, and the connection method is easy to operate. No steel bar binding operation is required at the work site, which greatly improves the connection speed and efficiency at the construction site.
[0061] It is worth noting that when the adjacent reinforced concrete module units on the left and right are connected, a gap is provided between the first prefabricated concrete wall panel 13 and the second prefabricated concrete wall panel 23, and a template is provided at the end to seal the two ends of the gap in the vertical direction, and then cast-in-place concrete is poured to form a cast-in-place concrete layer 3 after the cast-in-place concrete solidifies.
[0062] It should be noted that, in order to facilitate the hoisting of adjacent reinforced concrete module units on the same floor, the first precast concrete column 14 may not be set to a T-shape, and the second precast concrete column 24 may not be provided with the second U-shaped groove 241 .
[0063] Example 3
[0064] Another specific embodiment of the present invention discloses a method for connecting reinforced concrete modular buildings, which is used for connecting the reinforced concrete modular units of Example 2, and includes the following steps:
[0065] Step 1: Lift the first layer (i.e. lower layer) reinforced concrete module unit.
[0066] First, hoist the first reinforced concrete module unit. After the first reinforced concrete module unit is fixed, hoist the adjacent reinforced concrete module units on the left and right, leaving a gap between the adjacent two reinforced concrete module units, so that the adjacent reinforced concrete module units on the left and right correspond to the second groove 233 through the third steel truss 132, and the first concrete prefabricated column 14 and the second concrete prefabricated column 24 correspond to the T-shaped column through the second U-shaped groove 241 (it can also not be set in the form of a T-shaped column and a U-shaped groove), and set a template at the end of the reinforced concrete module unit so that the template blocks both ends of the gap. By analogy, the reinforced concrete module units of the first layer are arranged.
[0067] Step 2: Pour concrete between adjacent reinforced concrete module units.
[0068] Concrete is poured into the gaps between adjacent reinforced concrete module units of the first layer, and the formwork can be removed after the concrete solidifies.
[0069] Step 3: Pour concrete on top of the first layer (ie, lower layer) of reinforced concrete module units.
[0070] The first U-shaped groove 211 of the second precast concrete beam 21 and the first groove 223 of the second precast concrete slab 22 are filled with cast-in-place high-fluidity concrete.
[0071] Step 4: Lift the second layer (i.e. upper layer) reinforced concrete module unit.
[0072] Before the concrete of the first layer is initially set, the lower end of the first precast concrete beam 11 of the second layer and the first steel bar truss 122 of the first precast concrete panel 12 are aligned with the first U-shaped groove 211 and the first groove 223 and fall into the groove. After the concrete is set, a template is set at the end of the second layer reinforced concrete module unit to block the two ends of the gap between adjacent reinforced concrete module units.
[0073] Step 5: Pour concrete between adjacent reinforced concrete module units.
[0074] Concrete is poured into the gaps between adjacent reinforced concrete module units on the second floor, and the formwork can be removed after the concrete solidifies.
