Description

Technical Field

[0001] The present application relates to the technical field of housing construction, and in particular to a quick-install housing building structure and a construction method. Background Art

[0002] When constructing reinforced concrete houses, the traditional construction method is mostly on-site construction. After the steel bars are built, the formwork is supported, and then concrete is poured and finally the formwork is removed. This construction method requires a large number of formworks, and the formwork support and removal also take a lot of time and manpower. It also takes a lot of time to build partition walls, and the construction period is long.

[0003] Integrated construction is a production method that combines factories and social collaboration. It is a new type of construction method currently in use. It produces concrete structures such as prefabricated wall panels in factories, and then transports the concrete structures to the construction site for assembly and integration, thereby improving construction efficiency. When assembling multiple concrete structures, two adjacent concrete structures are mainly connected by connecting nodes; concrete structures cast by concrete will have pre-embedded steel bars inside, and accordingly, connecting steel bars that match the pre-embedded steel bars need to be welded on the connecting nodes. Since all the joints are welded, there are high requirements for the position accuracy of each connecting node, otherwise it will be difficult to assemble or the verticality of the connection of the integrated building will be poor.

[0004] In addition, the integrated buildings in related technologies are also equipped with a large number of structural columns. The entire structure is complex and difficult to process in the factory. Integrated buildings usually also need to be equipped with a large number of steel structures as load-bearing structures, which have high requirements on the dimensional accuracy and assembly accuracy of the entire prefabricated module, and the safety and stability are not sufficiently guaranteed. Summary of the invention

[0005] In order to improve the simplicity and safety of house construction, the present application provides a quick-install house building structure and a construction method.

[0006] In the first aspect, the present application provides a quick-install housing building structure adopting the following technical solution:

[0007] A quick-install housing building structure, comprising a plurality of prefabricated modular units that can be assembled and combined, each of the modular units comprising a partition board, a bottom board and a top board that can be combined to form a box body;

[0008] In the same module unit, the partition wall board is vertically arranged on the bottom plate and the lower end of the partition wall board is fixedly connected to the outer peripheral edge of the bottom plate, the top plate is arranged on the partition wall board and the upper end of the partition wall board is fixedly connected to the outer peripheral edge of the top plate; the partition wall board includes a thick wall, a wall mold and a beam mold, the thickness of the thick wall does not exceed 250mm, and the thickness of the wall mold and the beam mold does not exceed 50mm; the side of the thick wall and the side of the wall mold are fixedly connected together, and the beam mold is located on the upper side of the thick wall;

[0009] Between two partition boards where two adjacent module units are abutted, the wall formwork of one partition board is arranged opposite to the wall formwork of the other partition board, and a mold cavity 1 for casting a shear wall is formed between the two wall formworks; the beam formwork of one partition board is arranged opposite to the beam formwork of the other partition board, and a mold cavity 2 for casting a beam is formed between the two beam formworks; the two opposite wall formworks are connected by a plurality of tension screws arranged at intervals.

[0010] In the quick-install house building structure of the present application, each module unit corresponds to a room, and several module units are assembled into a set of house buildings at the construction site, combined with cast-in-place shear walls, beams, slabs, etc. to form a stable building structure; the location where the shear wall needs to be cast corresponds to the wall formwork in the design cost application. In the process of assembling the module units, at the location where the shear wall needs to be cast, first install the module units on one side of the shear wall, then build the internal steel mesh of the shear wall, and then install the module units on the other side of the shear wall, and then pour concrete. For structures where there is no designed module unit on the outside of the shear wall, a temporary formwork can be built, and the temporary formwork can be removed after the shear wall is formed.

[0011] By adopting the above technical scheme, the wall formwork is used as the formwork of the shear wall, and the beam formwork is used as the formwork of the beam. In the two adjacent partition boards, a complete mold cavity 1 is formed between the corresponding two wall formworks for cast-in-place shear walls, and a complete mold cavity 2 is formed between the corresponding two beam formworks for casting beams. After the shear walls and beams are cast, the wall formwork serves as the outer layer of the shear wall, and the beam formwork serves as the outer layer of the beam. There is no need to remove the formwork, which greatly improves the construction efficiency.

[0012] In addition, water and electricity pipes can be integrated into thick walls in advance to reduce the construction period of later on-site decoration.

[0013] Optionally, the wall formwork is prefabricated by pouring reinforced concrete, and the thick wall is poured by pouring reinforced concrete after the wall formwork is formed, and the end of the wall formwork has an embedded steel plate for connecting to the vertically adjacent wall formwork; the end of the wall formwork adjacent to the thick wall has an iron tapping for connecting to the thick wall.

[0014] The thickness of the wall formwork is relatively thin, and it is not suitable for vertical casting. By adopting the above technical solution, it is convenient to manufacture and shape, and the welding and fixing of adjacent wall formworks can be realized; when casting thick walls, the embedded steel bars in the wall formwork are extended into the thick wall, and the connection with the thick wall is realized after being cast in situ, which is stable and reliable. In this application, the prefabricated wall formworks of the module units are connected by welding, and the wall formworks and other parts are connected by cast-in-situ. This can not only ensure the stability and convenience of the connection, but also avoid the problems of difficult to control assembly accuracy and large welding workload caused by welding after prefabrication of multiple whole surfaces.

[0015] Optionally, the wall formwork and the bottom plate in the module unit are cast in advance respectively, and the wall formwork is cast in a horizontal state, and then the wall formwork is erected and supported, and the thick wall, top plate and beam formwork are cast as a whole; and then the lower ends of the wall formwork and the thick wall are fixedly connected to the bottom plate.

[0016] The 30mm wall formwork thickness in this application is relatively thin. After the steel mesh is set inside, if the vertical formwork is poured, the concrete will not flow well in the mold cavity and will be easily blocked. Therefore, it is prefabricated horizontally first, which can ensure the quality of the wall formwork and reduce the difficulty of the construction process.

[0017] By adopting the above technical solution, the wall formwork is pre-manufactured, and after the wall formwork is cast in a horizontal state, it is erected and fixedly connected with the wall formwork to form a whole when casting thick walls, top plates and beam forms, which is simple to process and easy to construct.

[0018] Optionally, between two partition boards where two adjacent module units are abutted against each other, a plurality of truss bars are fixedly provided on the wall formwork of one partition board, and a plurality of reinforcing ribs are fixedly provided on the wall formwork of the other partition board, the truss bars and the reinforcing ribs are arranged in one-to-one correspondence, the tension screws pass through the reinforcing ribs and are screwed to the corresponding truss bars, and the tension screws are also screwed with locking nuts.

[0019] By adopting the above-mentioned technical scheme, when there is a wall form between two partition boards that fit together, a complete mold cavity for casting the shear wall is formed between the two wall formworks. The two wall formworks are respectively connected to the truss bars and the reinforcing ribs through tension screws, and are fastened and connected through locking nuts to form a stable structure, so that the two wall formworks can withstand the lateral stress of the concrete; and after the shear wall is cast and formed, these structures are buried in the shear wall, so that the wall formwork in this application is stably connected to the shear wall to form a whole, and the structure is stable and reliable.

[0020] Optionally, in the partition board on the same surface, the inner side surface of the thick wall is flush with the inner side surface of the wall mold, the inner side surface of the thick wall is flush with the inner side surface of the beam mold, the mold cavity one is located on the outside of the wall mold, and the mold cavity two is located on the outside of the beam mold.

[0021] By adopting the above technical solution, the wall formwork can be used as the outer wall surface of the shear wall, and the beam formwork can be used as the outer wall surface of the beam. The above structural arrangement is both beautiful and can realize the function of both as templates, killing two birds with one stone and being convenient and practical.

[0022] Optionally, the thick wall is provided with door openings and / or window openings.

[0023] By adopting the above technical solution, thick walls are used as non-load-bearing internal partition walls or exterior walls. Door openings and window openings are pre-designed, and door frames and windows can be directly installed without the need for secondary construction. This saves materials and simplifies the subsequent decoration construction of the house.

[0024] Optionally, the thickness of the thick wall is 100 mm, the thickness of the wall formwork and the beam formwork are both 30 mm; and the height of the beam formwork is 250 mm.

[0025] By adopting the above technical solution, this size can meet the standard requirements and functional requirements of house construction, saving materials while ensuring safety, and is cost-effective.

[0026] Optionally, a plurality of hooks are fixedly provided on the top plate.

[0027] By adopting the above technical solution, the hoisting of the entire module unit is facilitated.

[0028] Optionally, in each module unit, the bottom plate and the top plate are rectangular plates, and the partition boards are combined to form a rectangular frame structure.

[0029] By adopting the above technical solution, each module unit corresponds to a building room and forms a square room shape. The four-sided partition board combines with the bottom plate and the top plate to form a rectangular box structure. Different rooms can be designed with module units of different sizes and shapes according to different functions, and then combined to form a complete house building structure, thereby realizing rapid assembly of house buildings.

[0030] Optionally, in each module unit, two adjacent wall formworks are fixedly connected by welding corresponding embedded steel plates; two adjacent thick walls are fixedly connected by binding the steel meshes in the two thick walls and then casting them as a whole; adjacent thick walls and wall formworks are fixedly connected by inserting embedded steel bars in the wall formworks during the thick wall casting process so that the two are fixedly connected after the thick walls are formed.

[0031] By adopting the above technical solution, a stable connection of the entire module unit can be achieved.

[0032] In the second aspect, the present application provides a construction method for a quick-install housing building structure using the following technical solution:

[0033] A construction method for a quick-install housing building structure comprises the following steps:

[0034] S1. Design drawings: Design drawings of the quick-install house structure according to the house building planning drawings, design the same number of module units according to the house type and number of rooms in the house building planning drawings, and design the structure of the corresponding module units according to the corresponding structure and function of each room;

[0035] S2. Manufacturing module units: prefabricate each module unit in the factory. In the manufacturing of each module unit, reinforced concrete is first used to cast the wall formwork and bottom plate in the module unit, and then the formed wall formwork is placed at a predetermined work station, and the steel mesh of the thick wall and the top plate is built and supported, and the thick wall and the top plate are cast; finally, the structure with the wall formwork, thick wall and top plate is placed on the prefabricated bottom plate and fixed together to form a complete module unit;

[0036] S3. Assemble the module units: transfer the manufactured module units to the construction site for assembly; during the module assembly process, where the shear wall needs to be cast, first install the module units on one side of the shear wall, then build the internal steel mesh of the shear wall, and then install the module units on the other side of the shear wall, and then cast; after the shear wall is formed, build the internal steel mesh of the beam and the steel mesh of the upper part of the top plate, and finally cast the beam and the upper part of the top plate; or build the internal steel mesh of the shear wall, the internal steel mesh of the beam and the steel mesh of the upper part of the top plate together, and then install the module units on the other side of the shear wall and cast them as a whole.

[0037] In this application, the prefabricated module units and assembly drawings in this application are first designed according to the building apartment drawings, for example, wall molds are set corresponding to the positions of the shear walls in the building apartment drawings, beam molds are set corresponding to the positions of the beams in the building apartment drawings, and openings are set corresponding to other openings such as doors and windows; then the module units are prefabricated in the factory according to the drawings, and the module units corresponding to each room are independently formed. After the module units are transported to the construction site, the module units are assembled according to the drawings to form a complete set of house building structures. In the process of assembling the module units, the position of the shear wall needs to be cast. The module units on one side of the shear wall are first installed, and then the internal steel mesh of the shear wall is built, and then the module units on the other side of the shear wall are installed, and finally the shear wall is cast; the structure of the beam is cast in the same way. For structures without module units on the outside of the shear wall and the beam, a temporary template can be built, and the temporary template can be removed after the shear wall and the beam are formed. The top plate of the prefabricated module unit in this application is used as a floor plate of half the thickness of the floor of the house building, and the other half of the thickness of the floor plate is cast on it, so as to form a floor plate of full thickness.

[0038] By adopting the above technical solution, the integrated module unit in this application can be well connected with the cast-in-place shear wall and beam, ensuring its stability and reliability, and high safety; the wall formwork is used as the formwork of the shear wall, and the beam formwork is used as the formwork of the beam for the cast-in-place shear wall and beam. After the shear wall and beam are cast, the wall formwork is used as the outer layer of the shear wall, and the beam formwork is used as the outer layer of the beam. There is no need to remove the formwork, which greatly improves the construction efficiency. In addition, the entire module unit in this application omits complex structural columns, has a simple structure, and is easy to produce.

[0039] Optionally, in the above step S2, a 30 mm thick wall formwork is manufactured on a horizontal plane according to the drawing, and extended embedded steel bars are arranged around the wall formwork. Then the horizontal wall formwork is erected, and a steel mesh of the thick wall and the top plate is built; the embedded steel bars of the prefabricated wall formwork are connected to the steel mesh of the top plate and the thick wall, and the formwork is supported to pour concrete.

[0040] The 30mm wall formwork thickness in this application is relatively thin. After the steel mesh is set inside, if the vertical formwork is poured, the concrete will not flow well in the mold cavity and will be easily blocked. Therefore, it is prefabricated horizontally first, which can ensure the quality of the wall formwork and reduce the difficulty of the construction process.

[0041] By adopting the above technical solution, the prefabricated wall formworks of the module units in this application are connected by welding, and the wall formworks and other parts are connected by cast-in-place. This can ensure the stability and convenience of the connection and avoid problems such as difficulty in controlling assembly accuracy and large welding workload caused by welding after prefabrication of multiple entire surfaces.

[0042] Optionally, in the above step S2, a pre-embedded steel plate is provided during prefabrication of the base plate, and the lower ends of the wall formwork and the thick wall are welded to the base plate through the pre-embedded steel plate to form a whole; or reinforcement is anchored into the base plate through the bottom of the wall formwork or the thick wall, and then the base plate is cast to achieve the connection between the wall formwork and the thick wall and the base plate.

[0043] By adopting the above technical scheme, the wall formwork and the bottom plate are prefabricated separately, and then the thick wall and the top plate are cast, and the wall formwork is fixedly connected with the thick wall and the top plate to form a 5-sided structure with four sides and a top, and then placed on the prefabricated bottom plate and fixedly connected to form a modular unit overall structure. The whole process is easy to implement and the connection is firm.

[0044] As an alternative: When pouring thick walls and top slabs, you can make a U-shaped template and turn it upside down to pour the thick walls and top slabs. After the pouring is completed, turn the entire 5-hedron structure over and secure it to the bottom plate. This can simplify the formwork construction of the top slab.

[0045] In this application, the concrete strength grade of the 30mm thick wall formwork is C60 (concrete aggregate ≤ 10mm), and the other concrete strength grades are C45. The steel mesh is arranged in the center; the anchorage length of the steel bar is TAL=32d, d is the diameter of the anchor steel bar; the materials of the embedded steel plates and anchor steel bars used are Q235, the welds between the embedded steel plates are 6mm, and the welding rod is e43.

[0046] In summary, the present application includes at least one of the following beneficial technical effects:

[0047] 1. The quick-install house building structure in this application makes full use of the advantages of integrated buildings and improves construction efficiency through factory prefabrication. At the same time, after assembly, it is combined with cast-in-place shear walls and cast-in-place beams to form a complete house building with good stability, safety and reliability.

[0048] 2. The wall formwork and beam formwork in this application are very thin and basically do not occupy the space of the shear wall and the beam. As the formwork for casting the shear wall and the beam, it greatly facilitates the casting construction of the shear wall and the beam.

[0049] 3. The water and electricity pipelines can be pre-integrated in the module unit of the present application, thus reducing the construction period of the later on-site decoration.

[0050] 4. The two matching wall molds in the present application are fixedly connected by truss bars, reinforcing ribs and tension screws to form a stable structure that can withstand the lateral stress of concrete; and after the shear wall is cast, these structures are buried in the shear wall, so that the module unit in the present application is stably connected to the shear wall to form a whole, with a stable and reliable structure and high safety.

In this embodiment, the thickness of the thick wall 11a does not exceed 250 mm, and the size is preferably 80 mm to 200 mm. The thickness of the wall mold 11b and the beam mold 11c does not exceed 50 mm, and the size is preferably 20 mm to 40 mm.

[0061] Reference Figure 4 and Figure 5 , each module unit 1 also includes a bottom plate 12 and a top plate 13; in the same module unit 1, the partition wall board 11 is vertically arranged on the bottom plate 12 and the lower end of the partition wall board 11 is fixedly connected to the outer peripheral edge of the bottom plate 12, and the top plate 13 is arranged on the partition wall board 11 and the upper end of the partition wall board 11 is fixedly connected to the outer peripheral edge of the top plate 13; the four-sided partition wall board 11 and the bottom plate 12 and the top plate 13 form a rectangular parallelepiped.

[0062] Reference Figure 6 , the two opposite wall forms 11b are connected by a plurality of tension screws 2 arranged at intervals. Specifically, between two adjacent partition boards 11 abutting against each other, a plurality of truss bars 3 are fixed on the wall form 11b of one partition board 11, and a plurality of reinforcing ribs 4 are fixed on the wall form 11b of the other partition board 11. The truss bars 3 and the reinforcing ribs 4 are arranged one by one, and the tension screws 2 pass through the reinforcing ribs 4 and are screwed to the corresponding truss bars 3. The tension screws 2 are also screwed to the locking nuts 5. When there is a wall form 11b between the two partition boards 11 abutting against each other, a complete shear wall 6 for pouring is formed between the two wall forms 11b. The cavity mold cavity 14 is used for casting the shear wall 6. The two wall molds 11b are respectively connected to the truss ribs 3 and the reinforcing ribs 4 through the tension screws 2, and are locked and connected through the locking nuts 5 to form a stable structure, so that the two wall molds 11b can withstand the lateral stress of the concrete; and after the shear wall 6 is cast and formed, these structures are buried in the shear wall 6, so that the wall mold 11b in the present application is stably connected to the shear wall 6 to form a whole with stable and reliable structure; in the two fitting partition boards 11, the gap between the thick walls 11a can be left untreated.

[0063] In the present application, the wall formwork 11b is prefabricated by pouring reinforced concrete first, and the thick wall 11a is poured with reinforced concrete after the wall formwork 11b is formed. The end of the wall formwork 11b has embedded steel bars for connecting to the thick wall 11a, and the end of the wall formwork 11b has embedded steel plates for connecting to the vertically adjacent wall formwork 11b.

[0064] like Figure 2 As shown, the thick wall 11a in the present application is provided with a door opening 11a1 and / or a window opening 11a2; the thick wall 11a is used as a non-load-bearing internal partition wall or exterior wall, and the door opening 11a1 and the window opening 11a2 are pre-designed, so that the door frame and the window can be directly installed without the need for secondary construction, which saves materials and simplifies the subsequent decoration construction of the house building; a number of hooks 13a are also fixed on the top plate 13 to facilitate the hoisting of the entire module unit 1. In each module unit 1, the bottom plate 12 and the top plate 13 are rectangular plates, and the partition wall panels 11 are surrounded to form a rectangular frame structure; each module unit 1 corresponds to a building room and forms a square room shape. The four-sided partition wall panels 11 are combined with the bottom plate 12 and the top plate 13 to form a rectangular box structure. Different rooms can be designed with module units 1 of different sizes and shapes according to different functional divisions, and then combined to form a complete set of house building structures, thereby realizing rapid assembly of house buildings.

[0065] In this embodiment, as a preferred solution, the thickness of the thick wall 11a is 100mm, the thickness of the wall form 11b and the beam form 11c are both 30mm, and the height of the beam form 11c is 250mm. This size can meet the standard requirements and functional requirements of house construction, save materials and ensure safety, and has high cost performance.

[0066] The implementation principle of the embodiment of the present application is as follows: each module unit 1 in the quick-install house building structure of the present application corresponds to a room, and a number of module units 1 are assembled into a set of house buildings at the construction site, and a stable building structure is formed by combining cast-in-place shear walls 6, beams 7, slabs, etc.; the position where the shear wall 6 needs to be cast corresponds to the wall formwork 11b in the design cost application. In the process of assembling the module units 1, at the position where the shear wall 6 needs to be cast, the module unit 1 on one side of the shear wall 6 is installed first, and then the internal steel mesh of the shear wall 6 is built, and then the module unit 1 on the other side of the shear wall 6 is installed, and then concrete is poured. For structures where there is no designed module unit 1 on the outside of the shear wall 6, a temporary formwork can be built, and the temporary formwork can be removed after the shear wall 6 is formed. The wall form 11b is used as the formwork of the shear wall 6, and the beam form 11c is used as the formwork of the beam. In the two partition boards 11 that are close to each other, a complete mold cavity 14 is formed between the two corresponding wall forms 11b, which is used for casting the shear wall 6, and a complete mold cavity 2 15 is formed between the two corresponding beam forms 11c, which is used for casting the beam 7. After the shear wall 6 and the beam 7 are cast, the wall form 11b is used as the outer layer of the shear wall 6, and the beam form 11c is used as the outer layer of the beam 7. There is no need to remove the formwork, which greatly improves the construction efficiency. In addition, the water and electricity pipelines can be integrated into the thick wall 11a in advance to reduce the construction period of the later on-site decoration.

[0067] The 30mm thick wall formwork 11b in this application is relatively thin. After a steel mesh is set inside, if the vertical formwork is cast, the concrete has poor fluidity in the mold cavity and is easily blocked, so it is not suitable for vertical casting. In order to facilitate the production and molding of the wall formwork 11b, the wall formwork 11b is first prefabricated horizontally, which can ensure the quality of the wall formwork 11b and reduce the difficulty of the construction process; when pouring the thick wall 11a, the wall formwork 11b is erected and connected to the thick wall 11a through the pre-embedded steel bars in the wall formwork 11b, which is stable and reliable. In this application, the prefabricated wall formworks 11b of the module unit 1 are fixedly connected by welding, and the wall formwork 11b is fixedly connected to other parts by cast-in-place, which can not only ensure the stability and convenience of the connection, but also avoid the problems of difficult to control assembly accuracy and large welding workload caused by welding after multiple whole-surface prefabrication.

[0068] In each module unit 1 in the present application, two adjacent wall molds 11b are fixedly connected by welding corresponding embedded steel plates; two adjacent thick walls 11a are fixedly connected by tying and connecting the steel meshes in the two thick walls 11a and then integrally cast to form a fixed connection; adjacent thick walls 11a and wall molds 11b are fixedly connected by inserting embedded steel bars in the wall molds 11b during the cast-in-place process of the thick walls 11a so that the two are fixedly connected after the thick walls 11a are formed, thereby achieving a stable connection of the entire module unit 1.

[0069] This embodiment also discloses a construction method of a quick-install housing building structure, which comprises the following steps:

[0070] S1.

After the module unit 1 is transported to the construction site, each module unit 1 is assembled according to the drawing to form a complete set of house building structure. In the process of assembling the module unit 1, the position of the shear wall 6 needs to be cast, and the module unit 1 on one side of the shear wall 6 is first installed, and then the internal steel mesh of the shear wall 6 is built, and then the module unit 1 on the other side of the shear wall 6 is installed, and finally the shear wall 6 is cast; the structure of the beam 7 is cast in the same way. For the structure without the module unit 1 outside the shear wall 6 and the beam 7, a temporary template can be built, such as a large steel template, and the temporary template is removed after the shear wall 6 and the beam 7 are formed. In the present application, the top plate 13 of the prefabricated module unit 1 is used as a floor plate of half the thickness of the building floor, and the floor plate of the other half thickness is cast on top of it, so as to form a floor plate of full thickness.

There is no need to remove the mold, which greatly improves the construction efficiency. In addition, in the present application, the entire module unit 1 omits the complex structural column, has a simple structure, and is easy to produce.
