[0071] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0072] like Figure 1-Figure 15 As shown, an embodiment of the present application provides a building, which generally includes a load-bearing component 200, which is arranged in an upright state. Generally, the load-bearing component 200 is built on a foundation.

[0073] Generally, it is necessary to set a beam on the load-bearing component 200 to meet the construction requirements of pouring the floor slab or the roof. To this end, the present application provides an assembled prefabricated reinforced concrete beam 100 to meet the construction requirements.

[0074] Specifically, the assembled prefabricated reinforced concrete beam 100 comprises:

[0075] A first prefabricated assembly beam 1, wherein the first prefabricated assembly beam 1 comprises a first structural reinforcement member 11 and a first casting member 12, wherein the first structural reinforcement member 11 extends along the length direction of the first prefabricated assembly beam 1, and a first casting groove 121 is formed on the first casting member 12, and the first casting member 12 is cast on the first structural reinforcement member 11;

[0076] A second prefabricated assembly beam 2, wherein the second prefabricated assembly beam 2 comprises a second structural reinforcement member 21 and a second casting member 22, wherein the second structural reinforcement member 21 extends in the length direction of the second prefabricated assembly beam 2, and a second casting groove 221 is formed on the second casting member 22, and the second casting member 22 is cast on the second structural reinforcement member 21;

[0077] The first prefabricated assembly beam and the second prefabricated assembly beam are configured to be arranged crosswise with each other and the first casting groove and the second casting groove are integrally cast at the cross-connection position to form a casting connection piece 130 .

[0078] Specifically, the prefabricated reinforced concrete beam 100 includes a first prefabricated beam 1 and a second prefabricated beam 2 which are arranged crosswise. During the construction process, the first prefabricated beam 1 and the second prefabricated beam 2 are hoisted onto the load-bearing component 200, the first prefabricated beam 1 and the second prefabricated beam 2 are arranged crosswise, and the first casting groove and the second casting groove are also arranged crosswise; then, the on-site casting operation can be performed.

[0079] During the pouring process, since the first assembled precast beam 1 and the second assembled precast beam 2 are correspondingly provided with the first pouring groove 121 and the second pouring groove 221, and the first pouring groove 121 and the second pouring groove 221 intersect, the poured concrete is poured to the intersection of the first pouring groove 121 and the second pouring groove 221. After the concrete solidifies, a pouring connector 130 is formed at the intersection of the first pouring groove 121 and the second pouring groove 221. The pouring connector 130 can be used to firmly and reliably connect the first assembled precast beam 1 and the second assembled precast beam 2 at the intersection of the two.

[0080] In one embodiment, a plurality of first installation openings 122 arranged at intervals are formed on the first casting member 12 , and the openings of the first installation openings 122 face upward.

[0081] The first installation opening 122 is configured to allow the second assembly prefabricated beam 2 to be cross-arranged above the first structural reinforcement 11 and to avoid the second structural reinforcement 21 ; the second assembly prefabricated beam 2 is located in the first installation opening 122 .

[0082] The second casting member 22 is formed with a plurality of second installation openings 222 arranged at intervals, and the openings of the second installation openings 222 face downward.

[0083] In addition, the second installation opening 222 is configured to allow the first assembly precast beam 1 to be cross-arranged below the second structural reinforcement 21 and avoid the first structural reinforcement 11 ; the first assembly precast beam 1 is located in the second installation opening 222 .

[0084] In this way, a plurality of first assembly precast beams 1 and second assembly precast beams 2 are arranged crosswise to form a grid structure, and a bottom template can be placed in the hollow area of ​​the grid structure to block and form a casting space, and concrete is cast in the casting space. At the same time, concrete is also cast in the first casting groove 121 and the second casting groove 221 to form a casting connector 130. The first installation opening 122 is connected to the corresponding second installation opening 222, so that the first assembly precast beam 1 and the second assembly precast beam 2 are crosswise connected to each other.

[0085] The first casting groove 121 and the second casting groove 221 are configured to cast and form casting connectors 130 at the first installation opening 122 and the second installation opening 222 , and the casting connectors 130 are distributed in the first casting groove 121 and the second casting groove 221 .

[0086] Specifically, since the first casting groove 121 and the second casting groove 221 are connected and communicated by plugging together the first mounting port 122 and the second mounting port 222 during cross-assembly, when pouring concrete, concrete will be poured at the first mounting port 122 and the second mounting port 222 to form a casting connector 130 that extends and distributes to the first casting groove 121 and the second casting groove 221 at the same time, so that the first assembled precast beam 1 and the second assembled precast beam 2 can be firmly and reliably connected and fixed together through the casting connector 130.

[0087] For the assembled prefabricated reinforced concrete beam 100, since the cast parts are formed on the structural reinforcement parts by pouring concrete, the first structural reinforcement parts 11 and the second structural reinforcement parts 21 can be made of metal components such as steel bars and iron beams to enhance the overall structural strength of the first assembled prefabricated beam 1 and the second assembled prefabricated beam 2.

[0088] In addition, for the first structural reinforcement 11, both ends of the first structural reinforcement 11 will extend to the outside of the first casting 12, and then the two ends of the first structural reinforcement 11 can be used to effectively connect with the load-bearing component 200. Similarly, both ends of the second structural reinforcement 21 will extend to the outside of the second casting 22. For example, the load-bearing component 200 can be a steel frame, and the ends of the first structural reinforcement 11 and the second structural reinforcement 21 can be welded to the steel frame; or, the load-bearing component 200 can be a steel casting structure, so that after the steel frame of the load-bearing component is overlapped, during the casting process of the load-bearing component 200, the ends of the first structural reinforcement 11 and the second structural reinforcement 21 will be embedded in the casting structure of the load-bearing component 200.

[0089] In addition, since the first prefabricated assembly beam 1 and the second prefabricated assembly beam 2 are integrally cast in concrete, the manufacturing cost can be effectively reduced.

[0090] In one embodiment, if Figure 2 As shown, the first structural reinforcement 11 includes a first steel bar 111 , the first steel bar 111 extends along the length direction of the first assembled precast beam 1 , and the first casting 12 wraps around the outside of the first steel bar 111 .

[0091] Specifically, the first structural reinforcement 11 includes a first steel bar 111 as a reinforcement, and the first casting 12 is cast outside the first steel bar 111 so that the first steel bar 111 is built into the first casting 12. Both ends of the first steel bar 111 can extend outside the first casting 12.

[0092] In actual use, the first steel bar 111 can be an integral structure with concrete poured on the outside to form the first casting 12; or, the first steel bar 111 can be a segmented structure, with the ends of two adjacent segments of the first steel bar 111 poured in the first casting 12, and in order to increase the connection emphasis, the ends of the two adjacent segments of the first steel bar 111 have overlapping parts.

[0093] Similarly, if Figure 6-Figure 7 As shown, the first structural reinforcement member 11 includes a first reinforcement beam 112 , and the first casting member 12 is cast and formed on the upper portion of the first reinforcement beam 112 .

[0094] Specifically, the first structural reinforcement member 11 includes a first reinforcement beam 112 as a reinforcement member, and the first casting member 12 will be cast on the top of the first reinforcement beam 112 to support the first casting member 12 through the first reinforcement beam 112. In order to enhance the connection strength between the first reinforcement beam 112 and the first casting member 12, a plurality of first connecting members 113 are provided on the upper surface of the first reinforcement beam 112, and the first connecting members 113 are embedded in the first casting member 12. In the process of casting the first casting member 12 on the first reinforcement beam 112, the first connecting members 113 will be embedded in the first casting member 12, so that the first reinforcement beam 112 and the first casting member 12 are more reliably connected together.

[0095] In some embodiments, the first structural reinforcement member 11 may include both a first steel bar 111 and a first reinforcement beam 112 .

[0096] In one embodiment of the present application, Figure 3 As shown, the second structural reinforcement 21 includes a second steel bar 211 , the second steel bar 211 extends along the length direction of the second assembled precast beam 2 , and the second cast component 22 wraps around the outside of the second steel bar 211 .

[0097] Specifically, the second structural reinforcement 21 includes a second steel bar 211 as a reinforcement, and the second casting 22 is cast outside the second steel bar 211 so that the second steel bar 211 is built in the second casting 22. Both ends of the second steel bar 211 can extend outside the second casting 22.

[0098] In actual use, the second steel bar 211 can be an integral structure with concrete poured on the outside to form a second casting 22; or, the second steel bar 211 can be a segmented structure, with the ends of two adjacent segments of the second steel bar 211 poured in the second casting 22, and in order to increase the connection emphasis, the ends of the two adjacent segments of the second steel bar 211 have overlapping parts.

[0099] Similarly, if Figure 8-Figure 9 As shown, the first structural reinforcement member 11 includes a second reinforcement beam 212 , and the first casting member 12 is cast and formed at the lower portion of the second reinforcement beam 212 .

[0100] Specifically, the second structural reinforcement member 21 includes a second reinforcement beam 212 as a reinforcement member, and the second casting member 22 will be cast at the bottom of the second reinforcement beam 212, so as to support the second casting member 22 through the second reinforcement beam 212. In order to enhance the connection strength between the second reinforcement beam 212 and the second casting member 22, a plurality of second connecting members are provided on the lower surface of the second reinforcement beam 212, and the second connecting members are embedded in the second casting member 22. In the process of casting and processing the second casting member 22 on the second reinforcement beam 212, the second connecting members will be embedded in the second casting member 22, so that the second reinforcement beam 212 and the second casting member 22 are more reliably connected together.

[0101] In some embodiments, the second structural reinforcement 21 may include both a second steel bar 211 and a second reinforcement beam 212 .

[0102] In one embodiment of the present application, since the first casting 12 and the second casting 22 are correspondingly formed with the first mounting opening 122 and the second mounting opening 222, the setting of the first mounting opening 122 and the second mounting opening 222 will affect the structural emphasis of the first casting 12 and the second casting 22. In order to improve the structural strength of the first casting 12 and the second casting 22, the following improvements are made.

[0103] A first structural reinforcement member 123 is disposed in the first casting member 12 . The first structural reinforcement member 123 is arranged close to the first installation opening 122 and is configured to enhance the structural strength of the first casting member 12 at the first installation opening 122 .

[0104] Specifically, the first structural reinforcement 123 is made of a material with a higher structural strength than concrete, such as a metal component. During the casting of the first casting 12, the first structural reinforcement 123 will be embedded in the first casting 12. Since the first structural reinforcement 123 is distributed at the first installation opening 122, the first structural reinforcement 123 can increase the structural strength of the first casting 12 at the first installation opening 122.

[0105] The first structural reinforcement member 123 is arranged at the periphery of the first installation opening 122, and its specific structural form can be various. Fig.10 As shown, the first structural reinforcement member 123 may be a U-shaped structure to half wrap around the first installation opening 122; or Fig.11 As shown, the first structural reinforcement member 123 may be an L-shaped structure, and the first structural reinforcement members 123 are respectively arranged on both sides of the first installation opening 122 .

[0106] Likewise, a second structural reinforcement piece 223 is disposed in the second casting piece 22 . The second structural reinforcement piece 223 is arranged close to the second installation opening 222 and is configured to enhance the structural strength of the second casting piece 22 at the second installation opening 222 .

[0107] Specifically, the second structural reinforcement 223 is made of a material with a higher structural strength than concrete, such as a metal member. During the casting process of the second casting 22, the second structural reinforcement 223 will be embedded in the second casting 22. Since the second structural reinforcement 223 will be arranged at the upper position of the second installation opening 222, the second structural reinforcement 223 can increase the structural strength of the second casting 22 at the second installation opening 222.

[0108] The second structural reinforcement member 223 may have various specific structural forms, for example, the second structural reinforcement member 223 may be a plate-shaped structure, or the second structural reinforcement member 223 may be a rod-shaped structure.

[0109] In one embodiment of the present application, since the casting part is formed with a casting groove, in order to improve the structural strength of the casting part, a first reinforcing connector is further provided between the two side walls of the first casting groove 121. The first reinforcing connector is arranged to extend substantially perpendicular to the length direction of the first casting groove 121, and the two side portions of the first casting groove 121 are connected by the first reinforcing connector.

[0110] Similarly, a second reinforcing connector is provided between the two side walls of the second casting groove 221. The second reinforcing connector is substantially perpendicular to the length direction of the second casting groove 221 and connects the two side portions of the second casting groove 221.

[0111] The first reinforcing connector and the second reinforcing connector may be independent components. Taking the first reinforcing connector as an example, during the casting of the first casting 12, the two ends of the first reinforcing connector are embedded in the first casting 12. Alternatively, the first reinforcing connector and the second reinforcing connector may be casting structures. Taking the first reinforcing connector as an example, during the casting of the first casting 12, the first reinforcing connector and the first casting 12 are cast and formed integrally.

[0112] In addition, in order to realize the layered construction and roof construction of the building, the building also protects the casting layer 300 arranged to extend laterally, and the casting layer 300 will form the roof or floor slab.

[0113] During the pouring construction process, the pouring layer 300 is poured and formed on the assembled prefabricated reinforced concrete beam 100 and the load-bearing component 200 , and the pouring layer 300 is poured and connected with the pouring connector 130 .

[0114] Specifically, during the pouring process of the pouring layer 300, the pouring can be completed at one time with the pouring connector 130, that is, the poured concrete will fill the first pouring groove 121 and the second pouring groove 221, and will also fill the pouring space formed between the first assembled precast beam 1 and the second assembled precast beam 2.

[0115] In order to facilitate the pouring of the later pouring layer 300 so that concrete can be fully filled into the first pouring groove 121 and the second pouring groove 221, the first reinforcing connector and the second reinforcing connector are formed with a hollow structure to allow concrete to flow through the hollow structure.

[0116] In one embodiment of the present application, the first casting 12 is an integral structure and extends along the first structural reinforcement 11; or, the first casting 12 includes a plurality of first sub-castings, which are arranged at intervals along the first structural reinforcement 11, and the first installation opening 122 is formed between two adjacent first sub-castings. Figure 4 As shown, a removable first auxiliary connecting member 13 is provided between two adjacent first sub-casting members.

[0117] Specifically, during the casting process of the first casting piece 12, the first casting piece 12 can be extended and cast on the first structural reinforcement member 11 to form an integrated structure. Alternatively, during the casting process of the first casting piece 12, multiple first sub-casting pieces can be cast at intervals.

[0118] In addition, the first auxiliary connecting member 13 is used to connect between two adjacent first sub-casting members during transportation to enhance the structural strength of the first installation opening 122. During the construction of the building, the first auxiliary connecting member 13 can be disassembled. The first auxiliary connecting member 13 can be a connecting plate or a connecting rod, etc., and is connected between the two first sub-casting members by means of screw connection or the like.

[0119] Similarly, if Figure 5 As shown, the second casting member 22 is an integral structure and extends along the second structural reinforcement member 21; or, the second casting member 22 includes a plurality of second sub-casting members, and the plurality of second sub-casting members are arranged at intervals along the second structural reinforcement member 21. Figure 5 As shown, a second auxiliary connecting member 23 is provided between two adjacent second sub-casting members.

[0120] Specifically, during the casting process of the second casting piece 22, the second casting piece 22 can be extended and cast on the second structural reinforcement member 21 to form an integrated structure. Alternatively, during the casting process of the second casting piece 22, multiple second sub-casting pieces can be cast at intervals.

[0121] In addition, the second auxiliary connecting member 23 is arranged above the second installation opening 222 and will not interfere with the first assembled prefabricated beam 1 during hoisting installation. Therefore, the second auxiliary connecting member 23 does not need to be disassembled during the building construction process.

[0122] In one embodiment of the present application, a first supporting mounting member 124 is disposed on the outer wall of the first casting member 12 , and a second supporting mounting member 224 is disposed on the outer wall of the second casting member 22 .

[0123] Specifically, the first casting member 12 needs to meet the installation requirements of the bottom template during the later use process. For this purpose, a first support mounting member 124 can be provided on the outer wall of the first casting member 12. The first support mounting member 124 can meet the installation and fixing requirements of the bottom template. For example, the bottom template can be directly overlapped on the first support mounting member 124, or the bottom template can be fixedly connected to the first support mounting member 124 by screws.

[0124] Similarly, a second supporting mounting member 224 is provided on the outer side wall of the second casting member 22 to meet the installation and fixing requirements of the bottom formwork.

[0125] In another embodiment, if Fig.15 As shown, a filler 120 is disposed at the bottom of the first casting groove 121 and the bottom of the second casting groove 221 .

[0126] Specifically, in order to reduce the amount of concrete used in the casting layer 300 later, the amount of the casting layer 300 filled into the first casting groove 121 and the second casting groove 221 can be reduced. To this end, a filler 120 can be provided at the bottom of the first casting groove 121, and similarly, a filler 120 can be provided at the bottom of the second casting groove 221. The filler 120 can be filled with conventional building materials such as foam blocks and sound insulation pads.

[0127] Based on the above technical solution, the present application provides a building in which the first structural reinforcement 11 and the second structural reinforcement 21 of the prefabricated reinforced concrete beam 100 are respectively connected to the load-bearing component 200; the casting layer 300 is cast and formed on the prefabricated reinforced concrete beam 100, and the casting layer 300 is also filled into the first casting groove 121 and the second casting groove 221 of the prefabricated reinforced concrete beam 100.

[0128] In one embodiment of the present application, stirrups 110 are respectively provided on the first casting piece 12 and the second casting piece 22 of the assembled prefabricated reinforced concrete beam 100;

[0129] The casting layer 300 includes a truss 310 and a casting body 320 . The truss 310 is connected to the stirrups 110 , and the casting body 320 wraps the truss 310 and the stirrups 110 .

[0130] The casting body 320 and the casting connector 130 are integrally cast, or the casting body 320 and the casting connector 130 are separately cast.

[0131] Specifically, in order to improve the overall structural strength of the casting layer 300, a truss 310 is provided in the casting layer 300. The truss 310 can be processed by steel bar bundling or welding. At the same time, the truss 310 is further bundled or welded with the stirrups 110 of the prefabricated reinforced concrete beam 100. Then, a casting body 320 is cast on the truss 310 and the prefabricated reinforced concrete beam 100, so that the casting layer 300 and the prefabricated reinforced concrete beam 100 are firmly and reliably connected together.

[0132] For the cast connection member 130, after the first assembled precast beam 1 and the second assembled precast beam 2 are arranged crosswise with each other, a first pouring can be performed to pour concrete in the first pouring groove 121 and the second pouring groove 221 to form the cast connection member 130; then, a second pouring can be performed to form a cast body 320.

[0133] Alternatively, a one-time pouring method may be adopted, that is, after the first assembled precast beam 1 and the second assembled precast beam 2 are arranged crosswise with each other, concrete is poured at one time to simultaneously form the cast connector 130 and the cast body 320 of the integrated structure.

[0134] In another embodiment, the load-bearing component 200 may have various structural forms, for example, the load-bearing component 200 may be a cast structure or a steel frame structure.

[0135] like Fig.13 As shown, the load-bearing component 200 adopts a casting structure. During the construction of the building, the load-bearing component 200 also uses steel bars to build a frame first, and then a template is attached to the built frame for casting. The cast concrete forms the load-bearing component 200 around the built frame, and the cast concrete forms a casting layer 300 on the top. The ends of the first structural reinforcement 11 and the second structural reinforcement 21 are embedded in the casting structure of the load-bearing component 200, so that the load-bearing component 200, the assembled prefabricated reinforced concrete beam 100 and the casting layer 300 form an integrated structure.

[0136] like Fig.14 As shown, the load-bearing component 200 is cast and steel frame structure is adopted, the load-bearing component 200 is connected with the ends of the first structural reinforcement 11 and the second structural reinforcement 21, and then cast. In order to improve the connection strength, an auxiliary casting component 210 can be cast on the top of the load-bearing component, and the ends of the first structural reinforcement 11 and the second structural reinforcement 21 are embedded in the casting structure on the top of the load-bearing component 200.

[0137] In certain embodiments of the present application, when the overall span of the first assembly precast beam 1 and / or the second assembly precast beam 2 is relatively large, a segmented design can be performed according to the requirements of the on-site hoisting construction. That is, the first structural reinforcement 11 includes a plurality of first sub-structure reinforcements (not shown), each of which is cast with a first casting 12, and the first sub-structure reinforcement and the corresponding first casting 12 form a first assembly sub-precast beam; two adjacent first assembly sub-precast beams are connected together by pouring concrete.

[0138] Similarly, the second structural reinforcement includes multiple second sub-structural reinforcements, each of which is cast with a second casting part, and the second sub-structural reinforcement and the corresponding second casting part form a second assembly sub-precast beam; two adjacent second assembly sub-precast beams are connected together by pouring concrete.

[0139] Specifically, taking the first assembly prefabricated beam 1 including a plurality of first assembly sub-prefabricated beams as an example, each first assembly sub-prefabricated beam is transported to the construction site after being prefabricated in the factory. At the on-site stage, after the plurality of first assembly sub-prefabricated beams are hoisted into place, the first sub-structural reinforcements of two adjacent first assembly sub-prefabricated beams can be connected together by welding or bundling, and then concrete is poured at the connection parts of the two adjacent first assembly sub-prefabricated beams to connect the two first assembly sub-prefabricated beams together. Similarly, the hoisting and pouring method of the second assembly prefabricated beam 2 including a plurality of second assembly sub-prefabricated beams is the same as that of the first assembly prefabricated beam 1, and will not be repeated here.

[0140] In another embodiment of the present application, a construction method of the above-mentioned building is also provided. For the construction method, refer to Fig.12 The construction methods include:

[0141] The first prefabricated assembly beam 1 and the second prefabricated assembly beam 2 are hoisted onto the load-bearing component 200, so that the first prefabricated assembly beam 1 and the second prefabricated assembly beam 2 are arranged crosswise. Specifically, the first prefabricated assembly beam 1 and the second prefabricated assembly beam 2 are hoisted onto the load-bearing component 200, and the first installation opening 122 and the second installation opening 222 are butted against each other to meet the requirements of cross-assembly of the first prefabricated assembly beam 1 and the second prefabricated assembly beam 2. Fig.16As shown, after the first installation opening 122 and the second installation opening 222 are inserted together, there will be a gap between the adjacent edges of the first installation opening 122 and the second installation opening 222. In order to further improve the connection strength between the first assembly precast beam 1 and the second assembly precast beam 2 during the construction stage, and further improve the pressure that the pouring layer 300 needs to withstand during the load-bearing pouring construction, an auxiliary reinforcement 400 can also be provided at the plug-in position of the first installation opening 122 and the second installation opening 222. The cross-section of the auxiliary reinforcement 400 is an L-shaped structure. The auxiliary reinforcement 400 is connected to the outside of the first assembly precast beam 1 and the second assembly precast beam 2 and is arranged on the outside of the plug-in position of the first installation opening 122 and the second installation opening 222. In this way, four auxiliary reinforcements 400 are distributed on the outside of the plug-in position of the first installation opening 122 and the second installation opening 222 to improve the connection reliability of the first assembly precast beam 1 and the second assembly precast beam 2 at the plug-in position of the first installation opening 122 and the second installation opening 222. Meanwhile, during the pouring process of the pouring layer 300, since the auxiliary reinforcement 400 covers the outside of the plug-in position of the first installation opening 122 and the second installation opening 222, the concrete injected into the first pouring groove 121 and the second pouring groove 221 is blocked by the auxiliary reinforcement 400, and the concrete will not leak at the plug-in position of the first installation opening 122 and the second installation opening 222, so as to ensure that the first pouring groove 121 and the second pouring groove 221 can be filled with concrete, so as to improve the connection reliability between the first prefabricated beam 1 and the second prefabricated beam 2 and the pouring layer 300.

[0142] A bottom template is placed between the hollow areas formed by the first prefabricated beam 1 and the second prefabricated beam 2 to form a pouring space above the bottom template. Specifically, before pouring the pouring layer 300, a bottom template is first set in the hollow area to meet the requirements of pouring concrete.

[0143] The truss 310 is laid on the first prefabricated beam 1 and the second prefabricated beam 2, and the truss 310 spans the casting space. Specifically, before pouring concrete, the truss 310 is connected and fixed to the stirrups 110 on the prefabricated reinforced concrete beam 100 by bundling or welding.

[0144] Concrete is poured into the pouring space, the first pouring groove 121 and the second pouring groove 221 to form the pouring connector 130 and the pouring body 320 .

[0145] Compared with the prior art, the advantages and positive effects of the present application are: by using cast assembled prefabricated beams as cross beams, during the processing, castings are cast on the structural reinforcements to form castings, and in order to meet the installation requirements of the cross beams, a first mounting opening with an opening facing upward is formed on the first casting, and correspondingly, a second mounting opening with an opening facing downward is formed on the second casting, and the first casting and the second casting are cross-installed by cooperating with the first mounting opening and the second mounting opening. Since the assembled prefabricated beams are processed by casting, the structural strength can be met while reducing the manufacturing cost. The structural reinforcements extending to the outside of the castings can be effectively connected to the load-bearing components of the building to ensure that the assembled prefabricated reinforced concrete beams are reliably connected to the load-bearing components of the building, and the casting layer of the building will also be filled into the casting grooves formed by the castings, so that the assembled prefabricated reinforced concrete beams form an integrated structure with the load-bearing components and the casting layer to improve the construction quality of the building.
