Description

Technical Field

[0001] This utility model relates to the field of prefabricated housing technology, specifically to a formwork support system for the corner of a foamed concrete prefabricated house. Background Technology

[0002] Concrete prefabricated houses use reinforced concrete as their main load-bearing components. Concrete has excellent high-temperature resistance and is not easily combustible, giving concrete prefabricated houses excellent fire resistance. They can maintain structural stability in a fire, reducing casualties and property damage. The construction process for concrete prefabricated houses is relatively simple, allowing for quality control during construction, improving management efficiency, and reducing construction costs. Concrete prefabricated houses can be designed with diverse shapes and flexibility to meet different architectural needs. They also have good energy-saving and environmental protection effects, reducing energy waste and environmental pollution, making them an important building material for green housing.

[0003] Currently, in the factory manufacturing process of precast concrete houses, the precast wall panels are typically hoisted into place first. Then, formwork is erected at the corners of the house, and the formwork is supported and fixed. Finally, concrete is poured into the formwork at the corners to connect the wall panels. However, existing formwork systems use steel pipes, top supports, and other components to support and fix the formwork. Each house requires a large number of steel pipes and top supports, which are then dismantled after use. This results in high labor intensity, time-consuming and labor-intensive work for workers erecting the formwork system, and low efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a formwork support system for the corner of a foamed concrete prefabricated house, which can effectively reduce the labor intensity of workers during the construction of the prefabricated house, save time and effort, and improve construction efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0006] A formwork support system for the corner of a foamed concrete prefabricated house includes a template adapted to the corner of the prefabricated house and a support structure for supporting the template and the top plate of the prefabricated house. The support structure includes a column and a first support component and a second support component hinged to the side wall of the column in the circumferential direction. The first support component forms a tapered support part with a larger upper end and a smaller lower end. The larger end of the tapered support part acts on the top plate. The second support component forms a horizontal support part. The support end of the horizontal support part acts on the template.

[0007] In this design, the formwork must be compatible with the corners of the prefabricated building to ensure a tight fit to the shape and dimensions of the corners. The formwork material should have sufficient strength and rigidity to withstand the pressure and lateral thrust during concrete pouring.

[0008] As the main load-bearing components of the supporting structure, the columns should be installed vertically to ensure stability. The first support component is hinged to the circumferential side wall of the column, forming a tapered support section that is larger at the top and smaller at the bottom. This helps to distribute the load transmitted from the top slab and improve the overall stability of the supporting structure. The larger end of the tapered support section acts on the top slab to ensure that the top slab is effectively supported. The second support component is also hinged to the circumferential side wall of the column, forming a horizontal support section. The supporting end of the horizontal support section acts on the formwork to ensure that the formwork does not shift or deform during the pouring process.

[0009] The formwork system mainly consists of columns, templates, and two support components. The number of components is greatly reduced compared to existing formwork systems, and the erection process is also relatively simple. It only requires rotating the first and second support components to the appropriate positions, thereby reducing the labor intensity of workers, saving time and effort, and improving the efficiency of erection.

[0010] Optionally, a pad is provided between the top of the column and the top plate, and a fixing seat is provided on the side wall of the column. Multiple first support components and second support components are hinged to the fixing seat. The inside of the column has honeycomb holes that extend along the length of the column.

[0011] Optionally, the first support assembly includes a first connecting pipe, a first support rod, and a first adjusting block. The lower end of the first connecting pipe is hinged to the fixed seat, and the lower end of the first support rod is inserted into the first connecting pipe. The surface of the first support rod is provided with external threads along its length direction. The first adjusting block is provided with an internal threaded hole adapted to the external threads. The first adjusting block is threadedly connected to the first support rod. The diameter of the internal threaded hole is smaller than the outer diameter of the first connecting pipe. Multiple support assemblies rotate upward to form a conical support portion acting on the bottom surface of the top plate.

[0012] Optionally, the upper end of the first support rod is provided with a first support block, which is in close contact with the bottom surface of the top plate.

[0013] Optionally, the top surface of the first support block is provided with a plurality of anti-slip teeth, and the bottom surface of the top plate is provided with a limiting block located on the side of the first support block.

[0014] Optionally, the second support assembly includes a second connecting pipe, a second support rod, and a second adjusting block. One end of the second connecting pipe is hinged to the fixed base, and one end of the second support rod is inserted into the second connecting pipe. The surface of the second support rod is provided with external threads along its length. The second adjusting block is provided with an internal threaded hole adapted to the external threads. The second adjusting block is threadedly connected to the second support rod. The diameter of the internal threaded hole is smaller than the outer diameter of the second connecting pipe. When multiple support assemblies are rotated to a horizontal state, they constitute a horizontal support part acting on the template.

[0015] Optionally, the second connecting pipes are arranged in a cross shape, and the second connecting pipes correspond to the template.

[0016] Optionally, the end of the second support rod away from the column is provided with a second support block adapted to the template.

[0017] Optionally, the template includes an outer mold and an inner mold. Both the outer mold and the inner mold are L-shaped aluminum templates. The inner side of the outer mold is attached to the outer corner of the prefabricated house, and the outer side of the inner mold is attached to the inner corner of the prefabricated house. The outer mold and the inner mold are provided with corresponding through holes, and multiple through holes are distributed at intervals along the length of the template. A screw is provided between the outer mold and the inner mold. One end of the screw passes through two corresponding through holes on the outer mold and the inner mold. A locking nut located on the outer side of the outer mold and the inner mold is threaded onto the screw.

[0018] A foamed concrete prefabricated house includes four vertical panels, a top panel, and a rain shelter. The four vertical panels form a rectangle, and the top panel is located on top of the four vertical panels. One of the vertical panels has a window and a doorway, and the opposite vertical panel has a window. The rain shelter is located on top of the vertical panel with the doorway. The top panel is a composite panel with a concrete layer poured on it. Solar panels are installed on the concrete layer. The connection between the four vertical panels is achieved by installing formwork and then pouring concrete.

[0019] The beneficial effects of this utility model are:

[0020] 1. In this utility model, the first support component is hinged to the circumference of the column side wall, forming a tapered support part with a larger upper end and a smaller lower end. This helps to disperse the load transmitted from the top plate and improve the overall stability of the support structure. The larger end of the tapered support part acts on the top plate to ensure that the top plate is effectively supported. The second support component is also hinged to the circumference of the column side wall to form a horizontal support part. The support end of the horizontal support part acts on the template to ensure that the template does not shift or deform during the pouring process.

[0021] 2. The formwork system mainly consists of columns, templates, and two support components. The number of components is greatly reduced compared to existing formwork systems, and the erection process is also relatively simple. It is only necessary to rotate the first support component and the second support component to the appropriate position, thereby reducing the labor intensity of workers, saving time and effort, and improving the efficiency of erection.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0031] A formwork support system for the corner of a foamed concrete prefabricated house includes a template 6 adapted to the corner of the prefabricated house and a support structure for supporting the template 6 and the top plate 2 of the prefabricated house. The support structure includes a column 7 and a first support component and a second support component hinged to the side wall of the column 7. The first support component forms a tapered support part with a larger upper end and a smaller lower end. The larger end of the tapered support part acts on the top plate 2. The second support component forms a horizontal support part. The support end of the horizontal support part acts on the template 6.

[0032] In this embodiment, as Figure 1 and Figure 2 As shown, template 6 must be adapted to the corner of the prefabricated house to ensure a tight fit to the shape and size of the corner. The material of template 6 should have sufficient strength and rigidity to withstand the pressure and lateral thrust during concrete pouring. As the main load-bearing component of the supporting structure, column 7 should be installed vertically to ensure stability. The first support component is hinged to the circumferential side wall of column 7, forming a tapered support section that is larger at the top and smaller at the bottom. This helps to distribute the load transmitted from the top plate 2 and improve the overall stability of the supporting structure. The larger end of the tapered support section acts on the top plate 2 to ensure that the top plate 2 is effectively supported. The second support component is also hinged to the circumferential side wall of column 7 to form a horizontal support section. The supporting end of the horizontal support section acts on template 6 to ensure that template 6 does not shift or deform during the pouring process. The formwork system mainly consists of columns 7, formwork 6, and two support components. The number of components is greatly reduced compared to existing formwork systems, and the erection process is also relatively simple. It is only necessary to rotate the first support component and the second support component to the appropriate position, thereby reducing the labor intensity of workers, saving time and effort, and improving the efficiency of erection.

[0033] Furthermore, a pad 18 is provided between the top of the column 7 and the top plate 2, and a fixing seat 17 is provided on the side wall of the column 7. Multiple first support components and second support components are hinged to the fixing seat 17. The column 7 has honeycomb holes 22 inside, which extend along the length of the column 7.

[0034] Specifically, the pad 18 is mainly used to distribute the concentrated load of the top plate 2 on the column 7, and at the same time provide a certain buffering effect to protect the column 7 from direct impact. The material of the pad 18 should have sufficient strength and rigidity to withstand the load transmitted from the top plate 2. The size and shape of the pad 18 should be reasonably designed according to the load of the top plate 2 and the size of the column 7 to ensure that the pad 18 can fit tightly between the top of the column 7 and the top plate 2. The pad 18 is generally made of steel plate.

[0035] like Figure 3As shown, the fixing seat 17 is used to connect and support the first support assembly and the second support assembly. It has a certain strength and rigidity to ensure that the support assembly can be stably hinged to the column 7. The fixing seat 17 and the column 7 are integrally formed. The honeycomb holes 22 inside the column 7 are designed to reduce the weight of the column 7 while maintaining its sufficient strength and rigidity. By optimizing the shape, size, and distribution of the honeycomb holes 22, the material cost of the column 7 can be reduced while meeting the load-bearing requirements. The first support assembly forms a tapered support section with a larger upper end and a smaller lower end, which helps to distribute the load transmitted from the top plate 2 and improve the overall stability of the support structure. The larger end of the tapered support section should be tightly fitted to the top plate 2 to ensure that the top plate 2 is effectively supported. The second support assembly forms a horizontal support section to support the formwork 6. The support end of the horizontal support section should be tightly fitted to the formwork 6 to ensure that the formwork 6 does not shift or deform during the pouring process.

[0036] Furthermore, the first support assembly includes a first connecting pipe 8, a first support rod 9, and a first adjusting block 10. The lower end of the first connecting pipe 8 is hinged to the fixed seat 17. The lower end of the first support rod 9 is inserted into the first connecting pipe 8. The surface of the first support rod 9 is provided with external threads along its length. The first adjusting block 10 is provided with an internal thread hole that matches the external threads. The first adjusting block 10 is threadedly connected to the first support rod 9. The diameter of the internal thread hole is smaller than the outer diameter of the first connecting pipe 8. Multiple support assemblies rotate upward to form a conical support portion acting on the bottom surface of the top plate 2.

[0037] Furthermore, the upper end of the first support rod 9 is provided with a first support block 11, which is in close contact with the bottom surface of the top plate 2.

[0038] Furthermore, the top surface of the first support block 11 is provided with a plurality of anti-slip teeth, and the bottom surface of the top plate 2 is provided with a limiting block 12 located on the side of the first support block 11.

[0039] In this embodiment, as Figure 1As shown, the specific working principle of the first support component is as follows: The first connecting pipe 8 is a hollow tubular structure, and its lower end is hinged to the fixed seat 17, so the first connecting pipe 8 can rotate in the vertical plane with the hinge point as the axis. Multiple first connecting pipes 8 are provided. The lower end of the first support rod 9 is inserted into the first connecting pipe 8. A first adjusting block 10 is threaded onto the first support rod 9. The two ends of the first adjusting block 10 are located on the outside of the first support rod 9. A first support block 11 is integrally formed on the upper end of the first support rod 9. The first support block 11 is parallel to the top plate 2, and a limit block 12 is provided on the bottom surface of the top plate 2. The limit block 12 can be integrally cast with the top plate 2. The top plate 2 is a prefabricated composite plate. In use, the length of the first support rod 9 inserted into the first connecting pipe 8 can be changed by rotating the first adjusting block 10. By changing the distance between the first support block 11 and the top plate 2, and rotating the first connecting pipe 8 so that the first connecting pipe 8 is inclined, the first support block 11 is located inside the limiting block 12 and in contact with the side wall of the limiting block 12. Then, the first adjusting block 10 is rotated so that the first support block 11 presses against the bottom surface of the top plate 2 to bear the load of the top plate 2. The limiting block 12 can prevent the first support block 11 from slipping. In this way, multiple first connecting pipes 8 are distributed in an inclined manner, and multiple first connecting pipes 8 are evenly distributed in a ring on the fixed seat 17. Therefore, multiple first connecting pipes 8, first support rod 9, first support block 11 and first adjusting block 10 constitute a conical support part. Since the top surface of the top plate 2 will need to be poured with concrete later, this conical support part can better support the top plate 2 above.

[0040] Furthermore, the second support assembly includes a second connecting pipe 13, a second support rod 15, and a second adjusting block 14. One end of the second connecting pipe 13 is hinged to the fixed base 17, and one end of the second support rod 15 is inserted into the second connecting pipe 13. The surface of the second support rod 15 is provided with external threads along its length direction. The second adjusting block 14 is provided with an internal thread hole adapted to the external thread. The second adjusting block 14 is threadedly connected to the second support rod 15. The diameter of the internal thread hole is smaller than the outer diameter of the second connecting pipe 13. When the multiple support assemblies are rotated to a horizontal state, they form a horizontal support part acting on the template 6.

[0041] Furthermore, the second connecting pipe 13 is arranged in a cross shape, and the second connecting pipe 13 corresponds to the template 6.

[0042] Furthermore, the end of the second support rod 15 away from the column 7 is provided with a second support block 16 that is adapted to the template 6.

[0043] like Figure 2As shown, the specific working principle of the second support component is as follows: The second connecting pipe 13 is a hollow tubular structure, one end of which is hinged to the fixed base 17, so that the second connecting pipe 13 can also rotate in the vertical plane with the hinge point as the axis. There are four second connecting pipes 13, which are arranged in a cross shape. The four second connecting pipes 13 correspond to the templates 6 at the four corners of the prefabricated house. One end of the second support rod 15 is inserted into the second connecting pipe 13. The second support rod 15 is threaded with a second adjusting block 14. The two ends of the second adjusting block 14 are located on the outside of the second support rod 15. The end of the second support rod 15 away from the column 7 is integrally formed with a second support. The second support block 16 is L-shaped, which can better fit the shape of the template 6. In use, the length of the second support rod 15 inserted into the second connecting pipe 13 can be changed by rotating the second adjusting block 14, thereby changing the distance between the second support block 16 and the template 6. Rotating the second connecting pipe 13 makes the second connecting pipe 13 horizontal. Tightening the second adjusting block 14 makes the second support block 16 press against the template 6. Therefore, multiple second connecting pipes 13, second support rods 15, second support blocks 16 and second adjusting blocks 14 constitute a horizontal support part, which can better support the template 6.

[0044] In this solution, the entire formwork support system is basically integrated on the column 7. It is only necessary to rotate the first connecting pipe 8 and the second connecting pipe 13 to the designed position, then screw the first adjusting block 10 to make the first support block 11 press against the bottom surface of the top plate 2, and screw the second adjusting block 14 to make the second support block 16 press against the template 6. The installation of the formwork support system is completed. There are not a large number of parts in the whole process, and the number of parts is greatly reduced compared with the existing formwork support system. The erection process is also relatively simple. It is only necessary to rotate the first support component and the second support component to the appropriate position. As a result, the labor intensity of workers is reduced, time and effort are saved, and the erection efficiency is improved.

[0045] Furthermore, the template 6 includes an outer mold 602 and an inner mold 601. Both the outer mold 602 and the inner mold 601 are L-shaped aluminum templates 6. The inner side of the outer mold 602 is attached to the outer corner of the prefabricated house, and the outer side of the inner mold 601 is attached to the inner corner of the prefabricated house. The outer mold 602 and the inner mold 601 are provided with corresponding through holes, and multiple through holes are distributed at intervals along the length of the template 6. A screw 19 is provided between the outer mold 602 and the inner mold 601. One end of the screw 19 passes through two corresponding through holes on the outer mold 602 and the inner mold 601. A locking nut 20 located on the outer side of the outer mold 602 and the inner mold 601 is threaded onto the screw 19.

[0046] Specifically, template 6 consists of an outer mold 602 and an inner mold 601. Before installation, a release agent can be applied to the outer mold 602 and inner mold 601. The outer mold 602 and inner mold 601 are fixed together by screws 19 and locking nuts 20. Multiple through holes are provided along the length of template 6, resulting in a larger number of screws 19. After assembling the locking nuts 20, the locking effect on the inner mold 601 and outer mold 602 is better, preventing mold bursting. To further mitigate the risk of mold bursting, arc-shaped rods can be installed between opposing inner molds 601. The ends of the arc-shaped rods can be inserted into grooves on the inner side of the inner mold 601 plate 6. During later demolding, the screws 19 can remain embedded in the concrete at the corners. To enhance the strength at the corners, reinforcing steel bars 21 can be installed between the top corners of the inner mold 601 and outer mold 602.

[0047] like Figure 4 As shown, a foamed concrete prefabricated house includes four vertical panels 1, a roof panel 2, and a rain shelter 3. The four vertical panels 1 form a rectangle, and the roof panel 2 is located on top of the four vertical panels 1. One vertical panel 1 has a window 5 and a doorway 4, and the opposite vertical panel 1 also has a window 5. The rain shelter 3 is located on top of the vertical panel 1 with the doorway 4. The roof panel 2 is a composite panel with a concrete layer poured on it. Solar panels are installed on the concrete layer. Formwork 6 is installed at the joints of the four vertical panels 1 before concrete is poured to achieve the connection. Specifically, the vertical panels 1, roof panel 2, and rain shelter 3 are all panels with an internal foamed concrete layer 24. When the prefabricated house has only one floor, the rain shelter 3 provides rain protection. When the prefabricated house has multiple overlapping floors, the rain shelter 3 can serve as a passageway on the second floor and above. The rain shelter 3 is also connected to the roof panel 2 by pouring concrete. Of course, the roof panel 2 and the rain shelter 3 can be integrally formed. Figure 5 As shown, an L-shaped protrusion structure 23 beam is provided on the top of the vertical plate 1 without windows 5 and doorway 4. This allows the side formwork to be removed when pouring the concrete on the top plate. The wall panel with foamed concrete layer 24 can reduce the weight of the entire prefabricated house by about 50%. The beam of protrusion structure 23 and foamed concrete form a weight-reducing and heat-insulating wall beam integrated panel that does not require side formwork.

Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
