Description

Technical Field

[0001] The present application relates to the field of building technology, and in particular to an assembled prefabricated reinforced concrete beam and a building. Background Art

[0002] With the continuous development of the construction industry, residential and commercial buildings are often constructed using poured concrete. Typically, buildings include load-bearing components (such as load-bearing beams or load-bearing walls), the height of which is determined by the building's height. Furthermore, horizontally arranged poured beams are installed on these components to meet the requirements of pouring the roof, depending on the height of the different floors.

[0003] In the prior art, cast beams are usually constructed by setting up a steel frame on site and then casting the beams on site with formwork to form the cast beams and the roof slab as an integrated structure.

[0066] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0067] like Figures 1-15As 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.

[0068] Typically, a beam needs to be provided on the load-bearing component 200 to meet the requirements of pouring the floor slab or roof. To this end, the present application provides an assembled prefabricated reinforced concrete beam 100 to meet the construction requirements.

[0069] Specifically, the assembled prefabricated reinforced concrete beam 100 includes:

[0070] A first precast beam 1 is provided, wherein the first precast beam 1 comprises a first structural reinforcement 11 and a first casting 12. The first structural reinforcement 11 extends along the length of the first precast beam 1. The first casting 12 is provided with a first casting groove 121. The first casting 12 is cast on the first structural reinforcement 11.

[0071] A second precast beam 2 is provided, wherein the second precast beam 2 includes a second structural reinforcement 21 and a second casting 22. The second structural reinforcement 21 extends in the length direction of the second precast beam 2. A second casting groove 221 is formed on the second casting 22. The second casting 22 is cast on the second structural reinforcement 21.

[0072] 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 a cross-connection position to form a casting connection piece.

[0073] Specifically, the prefabricated reinforced concrete beam 100 includes a first prefabricated beam 1 and a second prefabricated beam 2 arranged in a crosswise arrangement. During construction, the first and second prefabricated beams 1 and 2 are hoisted onto the load-bearing component 200. The first and second prefabricated beams 1 and 2 are arranged in a crosswise arrangement, with the first and second casting grooves also arranged in a crosswise arrangement. Then, on-site casting can begin.

[0074] During the pouring process, since the first assembly precast beam 1 and the second assembly 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 into 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. Through the pouring connector 130, the first assembly precast beam 1 and the second assembly precast beam 2 can be firmly and reliably connected together at the intersection of the first pouring groove 121 and the second pouring groove 221.

[0075] 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.

[0076] The first installation opening 122 is configured to allow the second assembly prefabricated beam 2 to be arranged crosswise above the first structural reinforcement 11 and away from the second structural reinforcement 21 ; the second assembly prefabricated beam 2 is located in the first installation opening 122 .

[0077] 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.

[0078] In addition, the second installation opening 222 is configured to allow the first assembly precast beam 1 to be arranged crosswise below the second structural reinforcement 21 and away from the first structural reinforcement 11 ; the first assembly precast beam 1 is located in the second installation opening 222 .

[0079] In this way, multiple first assembly precast beams 1 and second assembly precast beams 2 are arranged crosswise to form a grid structure. The hollow areas of the grid structure can be covered by bottom templates to form a pouring space, in which concrete is poured. At the same time, concrete is also poured in the first pouring grooves 121 and the second pouring grooves 221 to form the pouring connector 130. The first installation openings 122 are connected to the corresponding second installation openings 222, so that the first assembly precast beams 1 and the second assembly precast beams 2 are crosswise connected to each other.

[0080] 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 . The casting connectors 130 are distributed in the first casting groove 121 and the second casting groove 221 .

[0081] Specifically, since the first casting groove 121 and the second casting groove 221 are connected and communicated by being plugged together through the first installation port 122 and the second installation port 222 during cross-assembly, when pouring concrete, concrete will be poured at the first installation port 122 and the second installation 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 are firmly and reliably connected and fixed together through the casting connector 130.

[0082] 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.

[0083] In addition, with respect to the first structural reinforcement 11, both ends of the first structural reinforcement 11 will extend outside the first casting 12, thereby effectively connecting the two ends of the first structural reinforcement 11 to the load-bearing component 200. Similarly, both ends of the second structural reinforcement 21 will extend outside the second casting 22. For example, the load-bearing component 200 may be a steel frame, and the ends of the first structural reinforcement 11 and the second structural reinforcement 21 may be welded to the steel frame; alternatively, the load-bearing component 200 may be a steel cast structure. In this way, 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 cast structure of the load-bearing component 200.

[0084] In addition, since the first assembled prefabricated beam 1 and the second assembled prefabricated beam 2 are integrally cast in concrete, the manufacturing cost can be effectively reduced.

[0085] In one embodiment, if Figure 2 As shown, the first structural reinforcement 11 includes a first steel bar 111 , which extends along the length direction of the first assembled precast beam 1 , and the first casting member 12 wraps around the outside of the first steel bar 111 .

[0086] Specifically, the first structural reinforcement 11 includes a first steel bar 111 as a reinforcement member, and the first casting 12 is cast outside the first steel bar 111 so that the first steel bar 111 is embedded in the first casting 12. Both ends of the first steel bar 111 can extend outside the first casting 12.

[0087] In actual use, the first steel bar 111 can be an integral structure with concrete poured on the outside to form a 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.

[0088] 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 .

[0089] Specifically, the first structural reinforcement 11 includes a first reinforcing beam 112 as a reinforcement member. The first casting 12 is cast on top of the first reinforcing beam 112, thereby supporting the first casting 12. To enhance the connection strength between the first reinforcing beam 112 and the first casting 12, a plurality of first connecting members 113 are provided on the upper surface of the first reinforcing beam 112. The first connecting members 113 are embedded in the first casting 12. During the casting process of the first casting 12 on the first reinforcing beam 112, the first connecting members 113 are embedded in the first casting 12, ensuring a more reliable connection between the first reinforcing beam 112 and the first casting 12.

[0090] In some embodiments, the first structural reinforcement 11 may include both a first steel bar 111 and a first reinforcement beam 112 .

[0091] In one embodiment of the present application, Figure 3 As shown, the second structural reinforcement 21 includes a second steel bar 211 , which extends along the length direction of the second assembled precast beam 2 , and the second casting member 22 wraps around the outside of the second steel bar 211 .

[0092] 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 into the second casting 22. Both ends of the second steel bar 211 can extend outside the second casting 22.

[0093] 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 cast 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.

[0094] Similarly, if Figure 8-Figure 9As 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 .

[0095] Specifically, the second structural reinforcement 21 includes a second reinforcing beam 212 as a reinforcement member. The second casting 22 is cast at the bottom of the second reinforcing beam 212, thereby supporting the second casting 22. To enhance the connection strength between the second reinforcing beam 212 and the second casting 22, a plurality of second connecting members are provided on the lower surface of the second reinforcing beam 212. The second connecting members are embedded in the second casting 22. During the casting process of the second casting 22 on the second reinforcing beam 212, the second connecting members are embedded in the second casting 22, ensuring a more reliable connection between the second reinforcing beam 212 and the second casting 22.

[0096] In some embodiments, the second structural reinforcement 21 may include both a second steel bar 211 and a second reinforcement beam 212 .

[0097] In one embodiment of the present application, since the first and second mounting openings 122 and 222 are correspondingly formed on the first casting 12 and the second casting 22, the setting of the first and second mounting openings 122 and 222 will affect the structural stress of the first and second castings 12 and 22. In order to improve the structural strength of the first and second castings 12 and 22, the following improvements are made.

[0098] A first structural reinforcement 123 is provided in the first casting member 12 . The first structural reinforcement 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 .

[0099] 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 process of the first casting 12, the first structural reinforcement 123 is embedded in the first casting 12. Since the first structural reinforcement 123 is located at the first installation opening 122, the first structural reinforcement 123 increases the structural strength of the first casting 12 at the first installation opening 122.

[0100] The first structural reinforcement 123 is arranged on the periphery of the first installation opening 122, and its specific structural forms are various. Figure 10 As shown, the first structural reinforcement 123 can be a U-shaped structure to half wrap around the first installation opening 122; or, as shown Figure 11 As shown, the first structural reinforcement piece 123 may be an L-shaped structure, and the first structural reinforcement piece 123 is respectively arranged on both sides of the first installation opening 122 .

[0101] Likewise, a second structural reinforcement 223 is provided in the second casting member 22 . The second structural reinforcement 223 is arranged close to the second installation opening 222 and is configured to enhance the structural strength of the second casting member 22 at the second installation opening 222 .

[0102] Specifically, the second structural reinforcement 223 is made of a material with higher structural strength than concrete, such as a metal component. 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 is arranged above the second installation opening 222, the second structural reinforcement 223 increases the structural strength of the second casting 22 at the second installation opening 222.

[0103] 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.

[0104] 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 sides of the first casting groove 121 are connected by the first reinforcing connector.

[0105] Similarly, a second reinforcing connector is provided between the two side walls of the second casting groove 221. The second reinforcing connector extends substantially perpendicular to the length direction of the second casting groove 221 and connects the two sides of the second casting groove 221.

[0106] The first reinforcement connector and the second reinforcement connector can be independent components. Taking the first reinforcement connector as an example, during the casting of the first casting 12, the two ends of the first reinforcement connector are embedded in the first casting 12. Alternatively, the first reinforcement connector and the second reinforcement connector can be cast structures. Taking the first reinforcement connector as an example, during the casting of the first casting 12, the first reinforcement connector and the first casting 12 are cast integrally.

[0107] In addition, in order to realize the layered construction and roof construction of the building, the building also protects the pouring layer 300 arranged in a transverse extension, and the pouring layer 300 will form the roof or floor slab.

[0108] During the pouring construction process, the pouring layer 300 is poured and formed on the prefabricated reinforced concrete beam 100 and the load-bearing component 200 , and the pouring layer 300 is connected to the pouring connector 130 by pouring.

[0109] 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.

[0110] In order to facilitate the subsequent pouring of the 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.

[0111] In one embodiment of the present application, the first casting part 12 is an integral structure and extends along the first structural reinforcement 11; or, the first casting part 12 includes a plurality of first sub-casting parts, and the plurality of first sub-casting parts are arranged at intervals along the first structural reinforcement 11, and the first installation opening 122 is formed between two adjacent first sub-casting parts. Figure 4 As shown, a detachable first auxiliary connecting member 13 is provided between two adjacent first sub-casting members.

[0112] 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 to form the first casting piece 12.

[0113] In addition, the first auxiliary connecting member 13 is used to connect between two adjacent first sub-castings during transportation to enhance the structural strength of the first mounting opening 122. The first auxiliary connecting member 13 can be removed during building construction. The first auxiliary connecting member 13 can be a connecting plate or connecting rod, etc., and is connected between the two first sub-castings using screws or other methods.

[0114] Similarly, if Figure 5 As shown, the second casting part 22 is an integral structure and extends along the second structural reinforcement 21; or, the second casting part 22 includes a plurality of second sub-casting parts, and the plurality of second sub-casting parts are arranged at intervals along the second structural reinforcement 21. Figure 5 As shown, a second auxiliary connecting member 23 is provided between two adjacent second sub-casting members.

[0115] 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.

[0116] 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.

[0117] In one embodiment of the present application, a first support mounting member 124 is provided on the outer wall of the first casting member 12 , and a second support mounting member 224 is provided on the outer wall of the second casting member 22 .

[0118] Specifically, the first casting member 12 needs to meet the installation requirements of the bottom formwork during later use. To this end, 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 fixation requirements of the bottom formwork. For example, the bottom formwork can be directly overlapped with the first support mounting member 124, or the bottom formwork can be fixed to the first support mounting member 124 with screws.

[0119] 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.

[0120] In another embodiment, Figure 15 As shown, a filler 120 is provided at the bottom of the first casting groove 121 and the bottom of the second casting groove 221 .

[0121] Specifically, in order to reduce the amount of concrete used in the later stage of the casting layer 300, 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. 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.

[0122] 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.

[0123] 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;

[0124] 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 .

[0125] The casting body 320 and the casting connector 130 are cast as one piece, or the casting body 320 and the casting connector 130 are cast as separate pieces.

[0126] Specifically, to enhance the overall structural strength of the casting layer 300, a truss 310 is provided within the casting layer 300. The truss 310 can be fabricated by tying or welding steel bars. Furthermore, the truss 310 is further tied or welded to the stirrups 110 of the prefabricated reinforced concrete beam 100. A casting body 320 is then cast over the truss 310 and the prefabricated reinforced concrete beam 100, thereby providing a secure and reliable connection between the casting layer 300 and the prefabricated reinforced concrete beam 100.

[0127] For the cast connector 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 connector 130; then, a second pouring can be performed to form the cast body 320.

[0128] 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 in one go to simultaneously form the cast connector 130 and the cast body 320 of the integrated structure.

[0129] 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.

[0130] like Figure 13 As shown, the load-bearing component 200 utilizes a cast structure. During building construction, a frame is first constructed using steel bars, and then formwork is attached to the constructed frame for pouring. The poured concrete forms the load-bearing component 200 around the constructed frame, and the poured concrete forms a cast layer 300 on top. The ends of the first and second structural reinforcements 11 and 21 are embedded in the cast structure of the load-bearing component 200, forming an integrated structure comprising the load-bearing component 200, the prefabricated reinforced concrete beam 100, and the cast layer 300.

[0131] like Figure 14As shown, the load-bearing component 200 is cast and steel framed. The load-bearing component 200 is connected to the ends of the first structural reinforcement 11 and the second structural reinforcement 21, and then cast. To improve the connection strength, an auxiliary casting member 210 can also be cast on the top of the load-bearing component. 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.

[0132] In certain embodiments of the present application, if the overall span of the first prefabricated assembly beam 1 and / or the second prefabricated assembly beam 2 is relatively large, a segmented design can be implemented based on on-site hoisting construction requirements. Specifically, the first structural reinforcement 11 includes multiple first sub-structural reinforcements (not shown), each of which is cast with a first cast member 12. These first sub-structural reinforcements and the corresponding first cast member 12 form a first prefabricated assembly beam; two adjacent first prefabricated assembly beams are connected together by pouring concrete.

[0133] 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.

[0134] Specifically, taking the first assembly prefabricated beam 1 including multiple 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 multiple 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 multiple second assembly sub-prefabricated beams is the same as that of the first assembly prefabricated beam 1, and will not be repeated here.

[0135] This application is for the specific construction method of the building, refer to Figure 12 Provide explanation.

[0136] The first assembly prefabricated beam 1 and the second assembly prefabricated beam 2 are hoisted onto the load-bearing component 200 so that the first assembly prefabricated beam 1 and the second assembly prefabricated beam 2 are arranged crosswise. Specifically, the first assembly prefabricated beam 1 and the second assembly prefabricated beam 2 are hoisted onto the load-bearing component 200 so that the first installation opening 122 and the second installation opening 222 are mated with each other to meet the cross-assembly requirement of the first assembly prefabricated beam 1 and the second assembly prefabricated beam 2. Figure 16As shown, since a gap will be left between the adjacent edges of the first installation opening 122 and the second installation opening 222 after they are plugged together, 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 phase and further increase the pressure that the pouring layer 300 needs to withstand during the load-bearing pouring construction, an auxiliary reinforcement member 400 can also be provided at the plug-in location of the first installation opening 122 and the second installation opening 222. The cross-section of the auxiliary reinforcement member 400 is an L-shaped structure. The auxiliary reinforcement member 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 location of the first installation opening 122 and the second installation opening 222. In this way, four auxiliary reinforcement members 400 are distributed on the outside of the plug-in location 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 location of the first installation opening 122 and the second installation opening 222. At the same time, during the pouring process of the pouring layer 300, the auxiliary reinforcement 400 covers the outside of the connection between the first and second installation openings 122, 222. The concrete injected into the first and second pouring grooves 121, 221 is blocked by the auxiliary reinforcement 400, and the concrete does not leak from the connection between the first and second installation openings 122, 222. This ensures that the first and second pouring grooves 121, 221 are fully filled with concrete, thereby improving the connection reliability between the first and second assembled precast beams 1, 2 and the pouring layer 300.

[0137] A bottom template is placed between the hollow area formed by the first precast beam 1 and the second precast 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.

[0138] A truss 310 is laid on the first prefabricated beam 1 and the second prefabricated beam 2, and 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.

[0139] 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 .

[0140] Compared with the prior art, the advantages and positive effects of the present application are: by adopting cast assembled precast beams as cross beams, during the processing, cast parts are cast on the structural reinforcement members, and in order to meet the installation requirements of the cross beams, a first installation opening with an opening facing upward is formed on the first casting member, and correspondingly, a second installation opening with an opening facing downward is formed on the second casting member, and the first installation opening and the second installation opening are coordinated to realize the cross installation of the first casting member and the second casting member, and since the assembled precast beams are processed by casting, the structural strength can be met while reducing the manufacturing cost, and the structural reinforcement members extending to the outside of the casting members can be effectively connected to the load-bearing components of the building to ensure that the assembled precast 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 groove formed by the casting member, so that the assembled precast reinforced concrete beams form an integrated structure with the load-bearing components and the casting layer, so as to improve the construction quality of the building.
