Description

Technical Field

[0001] The present application relates to the field of building technology, and in particular to an assembled 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. However, the on-site fabrication of the steel frame will extend the construction period.

[0004] To this end, Chinese Patent Publication No. CN104594555A discloses a prefabricated reinforced concrete beam with a transverse high-strength concrete partition and a construction method. The prefabricated reinforced concrete beam is formed in a prefabricated manner, and a longitudinal reinforcement 1 (6) is provided at the bottom and a longitudinal reinforcement 2 (8) is provided at the top. The longitudinal reinforcement 2 (8) at the top is further used to form a cast-in-place flange plate. Although the above scheme can achieve the construction requirements of wire formwork-free construction, the prefabricated reinforced concrete beam itself is formed with a cast-in-place flange plate. When the cast-in-place flange plate is used for building construction, it needs to meet the requirements of the size and shape of the corresponding building floor, resulting in poor versatility in use. At the same time, the cast-in-place flange plate increases the overall size of the prefabricated reinforced concrete beam, resulting in increased transportation costs. In view of this, how to design a technology that meets the requirements of prefabricated production to improve versatility in use and reduce transportation costs is the technical problem to be solved by this application. Summary of the Invention

[0005] The technical problem to be solved by this application is to provide a prefabricated building that meets the requirements of prefabricated production to improve versatility and reduce transportation costs.

[0006] The technical solution provided by this application is a prefabricated building, comprising:

[0007] A load-bearing component, wherein the load-bearing component is arranged vertically;

[0008] A casting layer, the casting layer comprising a truss and a casting body, the casting body being cast and formed on the truss;

[0009] An assembled precast beam, the assembled precast beam comprising a structural reinforcement and a casting part, the structural reinforcement extending along the length of the assembled precast beam, the casting part having a casting groove formed thereon, the casting part further provided with stirrups, and the casting part being cast on the structural reinforcement;

[0010] Among them, multiple prefabricated assembly beams are arranged side by side and set on the load-bearing component, and a first casting space is formed between two adjacent prefabricated assembly beams. The structural reinforcement extends to the end of the casting member and is anchored on the load-bearing component. The truss is connected to the stirrups and arranged above the first casting space. The casting body also fills the first casting space and the casting groove.

[0011] In one embodiment of the present application, a second casting space is further formed between the assembled precast beam and the load-bearing component;

[0012] The cast unit also fills the second casting space.

[0013] In one embodiment of the present application, the load-bearing component is a cast structure, and the cast body and the load-bearing component are cast integrally.

[0014] In one embodiment of the present application, the load-bearing component includes a load-bearing frame and an auxiliary casting component, and the auxiliary casting component is cast on the load-bearing frame;

[0015] The casting body and the auxiliary casting components are cast in one piece.

[0016] In one embodiment of the present application, the structural reinforcement comprises steel bars, the steel bars extend along the length direction of the assembled prefabricated beam, and the casting part wraps around the outside of the steel bars.

[0017] In one embodiment of the present application, the structural reinforcement member includes a reinforcement beam, and the cast member is cast and formed on the upper part of the reinforcement beam.

[0018] In one embodiment of the present application, a plurality of connecting members are provided on the upper surface of the reinforcing beam, and the connecting members are embedded in the casting member.

[0019] In one embodiment of the present application, a support mounting member is provided on the outer side wall of the casting member, and the support mounting member is configured to install a bottom template to support the casting body in the first casting space.

[0020] In one embodiment of the present application, a filler is provided at the bottom of the casting groove.

[0021] In one embodiment of the present application, the end of the casting piece forms a reinforcement connection portion, and the reinforcement connection portion is connected to the load-bearing component;

[0022] Wherein, the reinforced connection portion is a shear groove, a shear protrusion, or a rough surface formed on the end surface of the cast body.

[0023] Compared with the prior art, the advantages and positive effects of the present application are as follows: by using cast precast beams to be placed on load-bearing components to meet the casting load requirements of the casting layer, the precast beams are cast on structural reinforcements to form castings, which can meet the structural strength while reducing manufacturing costs. The structural reinforcements extending outside the castings can be effectively connected to the load-bearing components to ensure that the precast beams are reliably connected to the load-bearing components. The casting layer of the building is cast on-site and filled into the casting grooves formed by the castings, thereby forming an integrated structure with the load-bearing components and the casting layer. Since the casting layer can be cast on-site to meet the construction requirements of different buildings, during the construction process, only the spacing of the precast beams needs to be adjusted to meet the construction requirements of different buildings. The precast beams can meet the requirements of prefabricated production while also improving their versatility. In addition, since the precast beams are not equipped with flange plates, the compact structure of the precast beams is more conducive to large-scale centralized transportation, thereby reducing transportation costs.

[0045] 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.

[0046] like Figures 1-11As shown, one embodiment of the present application provides a prefabricated building, generally comprising a load-bearing component 2 arranged in an upright position. Typically, the load-bearing component 2 is constructed on a foundation. To facilitate the layered construction of the building and the construction of the roof, the building also includes a laterally extending cast layer 3, which will form the roof or floor slab.

[0047] In order to meet the construction requirements of the pouring layer 3, it is usually necessary to set beams on the load-bearing components 2 to meet the pouring construction requirements of the pouring layer 3. This application adopts assembled prefabricated beams 1 to meet the construction requirements of the pouring layer 3.

[0048] Specifically, the prefabricated building includes: a load-bearing component 2, a casting layer 3 and a plurality of prefabricated assembled beams 1.

[0049] The load-bearing components are arranged vertically.

[0050] The casting layer 3 includes a truss 31 and a casting body 32 . The casting body 32 is cast on the truss 31 .

[0051] The prefabricated assembly beam 1 includes a structural reinforcement 11 and a casting 12. The structural reinforcement 11 extends along the length of the prefabricated assembly beam 1. The casting 12 is formed with a casting groove 121. The casting is further provided with stirrups 13. The casting 12 is cast on the structural reinforcement 11.

[0052] Among them, multiple prefabricated assembled beams 1 are arranged side by side and set on the load-bearing component 2, and a first casting space 100 is formed between two adjacent prefabricated assembled beams 1. The structural reinforcement 11 extends to the end of the casting and is anchored on the load-bearing component. The truss 31 is connected to the stirrups 13 and is arranged above the first casting space. The casting body also fills the first casting space 100 and the casting groove.

[0053] Specifically, for the assembled precast beam 1, since the casting part 12 is formed on the structural reinforcement 11 by pouring concrete, the structural reinforcement 11 can be made of metal components such as steel bars 111 and iron beams to enhance the overall structural strength of the assembled precast beam 1.

[0054] After the casting part 12 is cast through the formwork, a casting groove 121 is formed on the casting part 12, and the casting groove 121 also extends along the length direction of the assembled precast beam 1. As for the structural reinforcement member 11, the two ends of the structural reinforcement member 11 will extend to the outside of the casting part 12, and then the two ends of the structural reinforcement member 11 can be effectively connected to the load-bearing component 2.

[0055] During the specific construction process of the prefabricated building, after the load-bearing components 2 are overlapped on the foundation, the prefabricated beams 1 are connected to the load-bearing components, so that multiple prefabricated beams 1 are arranged side by side.

[0056] During the on-site construction of the pouring layer 3, the trusses 31 are first connected to the prefabricated beams 1. Specifically, the trusses 31 are connected to the stirrups 13 on the prefabricated beams 1. Then, concrete can be poured. Furthermore, during the concrete pouring process, to ensure that the concrete can fill the first pouring space 100 formed between the prefabricated beams 1, a bottom formwork 4 is generally placed in the first pouring space 100 before pouring, and the bottom formwork 4 is used to support the poured concrete. Thus, after concrete is poured on the trusses 31 and the prefabricated beams 1 to form the pouring body 32, the pouring body 32 will fill the first pouring space 100 and the pouring groove 121, so that the pouring body 32 firmly connects the trusses 31, the prefabricated beams 1, and the load-bearing components 2, thereby enhancing the overall structural strength of the building.

[0057] In one embodiment, a second casting space 200 is further formed between the prefabricated assembly beam 1 and the load-bearing component 2 ; the cast structure also fills the second casting space 200 .

[0058] Specifically, in order to further improve the reliability of the connection, a second pouring space 200 is formed between the assembled precast beam 1 and the load-bearing component 2. During the pouring process of the casting body 32, the second pouring space 200 also supports concrete by configuring a bottom formwork 4 at the bottom, so that the casting body finally fills the second pouring space 200.

[0059] In one embodiment, the load-bearing component 2 can be a steel frame, and the end of the structural reinforcement 11 can be welded to the steel frame; or, the load-bearing component 2 can be a cast structure of steel bars 111. In this way, after the steel bar 111 frame of the load-bearing component is overlapped, the load-bearing component 2 and the casting layer 3 are cast together, and the end of the structural reinforcement 11 will be embedded in the casting structure of the load-bearing component 2.

[0060] like Figure 2 As shown, the load-bearing component 2 is a cast structure, and the cast unit 32 and the load-bearing component are cast integrally. The load-bearing component 2 can adopt a conventional support structure such as a conventional load-bearing wall or load-bearing beam, and is internally configured with a steel bar frame 111. After the steel bar frame 111 is overlapped and the precast beams 1 and trusses 31 are assembled, casting can be carried out. On the one hand, the cast unit 32 is cast on the top, and on the other hand, the cast structure is cast outside the steel bar frame 111.

[0061] like Figure 11As shown, the load-bearing component 2 includes a load-bearing frame 21 and auxiliary casting components 22, which are cast and formed on the load-bearing frame 21. The casting body 32 and the auxiliary casting components 22 are cast and formed integrally. The load-bearing component 2 utilizes a steel frame load-bearing frame 21 as its main structure, and the auxiliary casting components 22 are cast on-site at the top of the load-bearing frame 21. During on-site construction, the load-bearing frame 21 is fixed to the foundation and the precast beams 1 are connected to the load-bearing frame. After the trusses 31 are laid, casting can begin. The casting body 32 and the auxiliary casting components 22 are cast and formed integrally on-site.

[0062] In one embodiment, if Figure 9 As shown, the structural reinforcement 11 includes a steel bar 111 , and the steel bar 111 extends along the length direction of the assembled precast beam 1 , and the casting member 12 wraps around the outside of the steel bar 111 .

[0063] Specifically, the structural reinforcement 11 includes a steel bar 111 as a reinforcement, and the casting 12 is cast outside the steel bar 111 so that the steel bar 111 is built into the casting 12. Both ends of the steel bar 111 can extend outside the casting 12.

[0064] In another embodiment, Figure 9 As shown, the structural reinforcement member 11 includes a reinforcement beam 112 , and the casting member 12 is cast and formed on the upper portion of the reinforcement beam 112 .

[0065] Specifically, the structural reinforcement 11 includes a reinforcing beam 112 as a reinforcement member. The casting 12 is cast on top of the reinforcing beam 112, thereby supporting the casting 12. To enhance the connection strength between the reinforcing beam 112 and the casting 12, the upper surface of the reinforcing beam 112 is provided with a plurality of connectors 113, which are embedded in the casting 12. During the casting process of the casting 12 on the reinforcing beam 112, the connectors 113 are embedded in the casting 12, ensuring a more reliable connection between the reinforcing beam 112 and the casting 12.

[0066] A plurality of connecting members 113 are provided on the upper surface of the reinforcing beam 112 , and the connecting members 113 are embedded in the casting member 12 .

[0067] In some embodiments, the structural reinforcement 11 may include both steel bars 111 and reinforcement beams 112 .

[0068] In one embodiment of the present application, a support mounting member 14 is provided on the outer side wall of the casting member 12 , and the support mounting member 14 is configured to install a bottom template 4 to support the casting body in the first casting space 100 .

[0069] Specifically, during later use, the casting 12 needs to meet the installation requirements of the bottom formwork 4. To this end, a support mounting member 14 can be provided on the outer wall of the casting 12. The support mounting member 14 can meet the installation and fixation requirements of the bottom formwork 4. For example, the bottom formwork 4 can be directly overlapped on the support mounting member 14, or the bottom formwork 4 can be fixed to the support mounting member 14 by screws.

[0070] In one embodiment of the present application, Figure 11 As shown, a filler 12215 is provided at the bottom of the casting groove 121 .

[0071] Specifically, in order to reduce the amount of concrete used in the later stage of the pouring layer 3, the amount of concrete used in the pouring groove 121 can be reduced. To this end, a filler 12215 can be provided at the bottom of the pouring groove 121. The filler 12215 can be filled with conventional building materials such as foam blocks and sound insulation pads.

[0072] In one embodiment of the present application, Figure 12 As shown, the end of the casting member 12 forms a reinforcement connection portion 123, and the reinforcement connection portion 123 is connected to the load-bearing component 2;

[0073] The reinforced connection portion 123 is a shear groove, a shear protrusion, or a rough surface formed on the end surface of the cast body 32 .

[0074] Specifically, since casting 12 is a prefabricated structure, a reinforced connection portion 123 can be added to the end surface of casting 12 to improve the connection strength between casting 12 and the on-site cast material. Reinforced connection portion 123 can enhance the connection strength with load-bearing component 2. Specifically, during the pouring process of casting unit 32 and the corresponding parts of load-bearing component 2, concrete can form a strong connection with reinforced connection portion 123, thereby improving the reliability of the connection between casting 12, casting unit 32, and load-bearing component 2.

[0075] Compared with the prior art, the advantages and positive effects of the present application are as follows: by using cast precast beams to be placed on load-bearing components to meet the casting load requirements of the casting layer, the precast beams are cast on structural reinforcements to form castings, which can meet the structural strength while reducing manufacturing costs. The structural reinforcements extending outside the castings can be effectively connected to the load-bearing components to ensure that the precast beams are reliably connected to the load-bearing components. The casting layer of the building is cast on-site and filled into the casting grooves formed by the castings, thereby forming an integrated structure with the load-bearing components and the casting layer. Since the casting layer can be cast on-site to meet the construction requirements of different buildings, during the construction process, only the spacing of the precast beams needs to be adjusted to meet the construction requirements of different buildings. The precast beams can meet the requirements of prefabricated production while also improving their versatility. In addition, since the precast beams are not equipped with flange plates, the compact structure of the precast beams is more conducive to large-scale centralized transportation, thereby reducing transportation costs.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
