Foundation frame for a fabricated building

Abstract

This utility model discloses a foundation frame for prefabricated buildings, relating to the field of building engineering technology. The utility model includes a concrete foundation, with an intermediate frame connected to the top of the concrete foundation. A limiting plate is connected inside the intermediate frame, and limiting holes are formed at the bottom of the limiting plate. Grasping frames are connected to both sides of the bottom of the intermediate frame, and horizontal bracing plates are fixed to both sides inside the grasping frames. Through the arrangement of the intermediate frame, vertical reinforcement, limiting plate, and limiting holes, the vertical reinforcement is tied together with the reinforcing bars within the concrete foundation before pouring the concrete.

The structure has good stability and effectively prevents displacement and overturning of the foundation frame.

Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a foundation frame for prefabricated buildings. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories are processed and manufactured in factories, transported to the construction site, and assembled on-site using reliable connection methods. Like traditional construction methods, prefabricated buildings require foundation fixation to prevent the building from collapsing.

[0003] A prefabricated building foundation structure, application number 202320431363.5, includes a base plate, an assembly plate, an assembly groove, mounting holes, and assembly openings. In this invention, the assembly plate, assembly groove, and assembly openings are designed so that, during use, the lower end of the wall panel is engaged in the assembly groove, and bolts are inserted into the assembly openings and fixing holes of the wall panel. This facilitates a stable connection between the foundation structure and the wall panel, promotes rapid connection, and improves the performance of the foundation structure. The reinforcing rods are inserted into the pouring groove, where concrete is poured, integrating the concrete and reinforcing rods to ensure a reliable connection between the foundation structure and the concrete foundation, guaranteeing normal operation of the foundation structure. The stabilizing plates, located on both sides of the reinforcing rods, increase the contact area between the reinforcing rods and the concrete foundation, preventing loosening of the reinforcing rods during use and ensuring a stable connection between the reinforcing rods and the concrete foundation.

[0004] This technical solution uses an inclined stabilizing plate as a hook to connect the foundation structure to the foundation. This connection method mainly relies on the concrete to bear the pressure. However, the small size of the stabilizing plate results in a small pressure area, which leads to greater pressure on the concrete. This can easily cause the concrete to break and the foundation structure to fall off. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a foundation frame for prefabricated buildings to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foundation frame for a prefabricated building, including a concrete foundation, an intermediate frame connected to the top of the concrete foundation, and a limiting plate connected inside the intermediate frame, with limiting holes opened at the bottom of the limiting plate, gripping frames connected to both sides of the bottom of the intermediate frame, and horizontal support plates fixed to both sides inside the gripping frames, and vertical bars and grid bars connected inside the concrete foundation.

[0007] By adopting the above technical solution, before pouring the concrete foundation, workers tie the vertical reinforcement and the grid reinforcement together with the steel bars in the concrete foundation. Then, workers place the intermediate frame from top to bottom and support it above the concrete foundation with some items. Because the bottom of the limiting hole is truncated cone-shaped with an inclined surface, it is easy for the vertical reinforcement to pass through the limiting hole and the limiting plate. Then, workers pour concrete from the bottom of the intermediate frame and from the top of the intermediate frame into the intermediate frame. At this time, the setting of the limiting plate and the limiting hole prevents the vertical reinforcement from shifting and affecting the stress. After the concrete solidifies, it firmly fixes the intermediate frame to the concrete foundation. At the same time, the vertical reinforcement bears the force, effectively preventing the intermediate frame from overturning and shifting. The concrete will adhere to the perimeter of the gripping frame. Because the cross-section of the gripping frame is V-shaped, the gripping frame is similar to a barb. When the intermediate frame is subjected to an upward force, the intermediate frame can grip the concrete foundation with the gripping frame and the grid reinforcement, further preventing the intermediate frame from overturning. At the same time, the horizontal bracing plate increases the structural strength of the gripping frame and reduces the phenomenon of inward bending deformation of the gripping frame.

[0008] Furthermore, three limiting plates are provided, and the three limiting plates are distributed at equal intervals.

[0009] By adopting the above technical solution, workers pour concrete from below the intermediate frame and from the top of the intermediate frame into the intermediate frame. At this time, the setting of the limiting plate and limiting hole prevents the vertical reinforcement from shifting and affecting the stress.

[0010] Furthermore, the bottom of the limiting hole is frustum-shaped, and the vertical ribs penetrate the top and bottom of the limiting hole.

[0011] By adopting the above technical solution, the staff placed the intermediate frame from top to bottom and supported it above the concrete foundation with some items. Since the bottom of the limiting hole is shaped like a frustum and has an inclined surface, it is easy for the vertical reinforcement to pass through the limiting hole and penetrate the limiting plate.

[0012] Furthermore, there are twenty-seven limiting holes and nine vertical ribs.

[0013] By adopting the above technical solution and increasing the number of vertical ribs, the number of support points of the structure is increased, which greatly improves the stability of the intermediate frame.

[0014] Furthermore, the cross-section of the gripping frame is in the shape of an "eight".

[0015] By adopting the above technical solution, since the cross-section of the gripping frame is V-shaped, the gripping frame is similar to a barb. When the intermediate frame is subjected to an upward force, the intermediate frame can grip the concrete foundation through the gripping frame and the grid reinforcement, further preventing the intermediate frame from overturning.

[0016] Furthermore, the cross brace is triangular in shape, and there are four cross braces.

[0017] By adopting the above technical solution, the cross brace increases the structural strength of the gripper and reduces the occurrence of inward bending deformation of the gripper.

[0018] Furthermore, multiple mounting holes are provided on the top, back, sides, top sides, and bottom sides of the outer surface of the intermediate frame. A crossbeam is connected to one side of the intermediate frame, and a column is connected to the top of the intermediate frame.

[0019] By adopting the above technical solution, after the intermediate frame and concrete foundation are constructed, the workers remove the bottom support of the intermediate frame. Then, the workers can insert the crossbeams from both sides, the outer surface and the back of the intermediate frame, and then fasten the crossbeams by using through bolts through the mounting holes. The columns are inserted from the top of the intermediate frame, and then fastened by using through bolts through the mounting holes.

[0020] Furthermore, ribs are fixed around the perimeter of the intermediate frame.

[0021] By adopting the above technical solution, the structural strength of the intermediate frame is increased by using ribs, which can achieve the effects of diagonal bracing and diagonal tension, thereby reducing the occurrence of bending deformation of the intermediate frame.

[0022] Furthermore, the surface of the rib plate is hollowed out.

[0023] By adopting the above technical solution, the weight of the rib plate is reduced while ensuring the strength of the diagonal bracing and diagonal tension, thus reducing resource consumption, due to the hollow surface of the rib plate.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, through the setting of an intermediate frame, vertical reinforcement, limiting plate, and limiting hole, allows the vertical reinforcement to be tied together with the steel reinforcement in the concrete foundation before pouring the concrete foundation. Then, the intermediate frame is placed from top to bottom and supported above the concrete foundation by some objects. Since the bottom of the limiting hole is truncated cone with an inclined surface, it is easy for the vertical reinforcement to pass through the limiting hole and the limiting plate. Then, concrete is poured below the intermediate frame and from the top of the intermediate frame into the intermediate frame. At this time, the setting of the limiting plate and limiting hole prevents the vertical reinforcement from shifting and affecting the stress. After the concrete solidifies, the intermediate frame is firmly fixed to the concrete foundation. At the same time, the vertical reinforcement bears the force, effectively preventing the intermediate frame from overturning and shifting. The structure has good stability and effectively prevents the foundation frame from shifting and overturning.

[0026] 2. This utility model, through the arrangement of the gripping frame, cross bracing plate, and grid reinforcement, binds the grid reinforcement to the steel bars in the concrete foundation before pouring the concrete foundation. When pouring the concrete foundation, the concrete will adhere to the perimeter of the gripping frame. Since the gripping frame has an eight-shaped cross section, it resembles a hook. When the middle frame is subjected to an upward force, it can grip the concrete foundation through the gripping frame and the grid reinforcement, further preventing the middle frame from tipping over. At the same time, the cross bracing plate increases the structural strength of the gripping frame and reduces the phenomenon of inward bending deformation, further improving the stability of the structure. In addition, the large force application area and the force distribution through the grid reinforcement prevent the concrete foundation from being broken by the force applied by the gripping frame.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure. Example 1

[0034] A foundation frame for a prefabricated building, such as Figures 1-4As shown, the structure includes a concrete foundation 1, with an intermediate frame 2 connected to the top of the concrete foundation 1. Inside the intermediate frame 2 are three limit plates 8, equidistantly distributed. Each limit plate 8 has twenty-seven limit holes 9 at its bottom, each with a frustum-shaped bottom. Grasping frames 10 are connected to both sides of the bottom of the intermediate frame 2, with a cross-section shaped like the number "8". Four horizontal support plates 11 are fixed to both sides of the inside of each gripping frame 10, each triangular in shape. Nine vertical reinforcement bars 7 and crisscross reinforcement bars 12 are connected inside the concrete foundation 1, penetrating the top and bottom of the limit holes 9. Before pouring the concrete foundation 1, workers tie the vertical reinforcement bars 7 and crisscross reinforcement bars 12 to the reinforcing bars inside the concrete foundation 1. Then, workers place the intermediate frame 2 from top to bottom and support it above the concrete foundation 1 using various objects. Because the bottom of the limiting hole 9 is truncated cone-shaped with an inclined surface, it is easy for the vertical reinforcement 7 to pass through the limiting plate 8 through the limiting hole 9. Then, the workers pour concrete below the intermediate frame 2 and from the top of the intermediate frame 2 into the intermediate frame 2. At this time, the setting of the limiting plate 8 and the limiting hole 9 prevents the vertical reinforcement 7 from shifting and affecting the stress. After the concrete solidifies, it firmly fixes the intermediate frame 2 to the concrete foundation 1. At the same time, the vertical reinforcement 7 bears the force, effectively preventing the intermediate frame 2 from overturning and shifting. The concrete will adhere to the perimeter of the gripping frame 10. Because the cross section of the gripping frame 10 is V-shaped, the gripping frame 10 is similar to a barb. When the intermediate frame 2 is subjected to an upward force, the intermediate frame 2 can grip the concrete foundation 1 through the gripping frame 10 and the grid reinforcement 12, further preventing the intermediate frame 2 from overturning. At the same time, the horizontal support plate 11 increases the structural strength of the gripping frame 10 and reduces the phenomenon of the gripping frame 10 bending and deforming inward.

[0035] See Figures 1-3 In the above embodiment, multiple mounting holes 3 are provided on the top, back, sides, top sides, and bottom sides of the outer surface of the intermediate frame 2. A crossbeam 5 is connected to one side of the intermediate frame 2, and a column 6 is connected to the top of the intermediate frame 2. After the intermediate frame 2 and the concrete foundation 1 are constructed, the workers remove the bottom support of the intermediate frame 2. Then, the workers can insert the crossbeam 5 from the sides, outer surface, and back of the intermediate frame 2, and then fasten the crossbeam 5 by passing bolts through the mounting holes 3. The column 6 is inserted from the top of the intermediate frame 2, and then fastened by passing bolts through the mounting holes 3. Example 2

[0036] Based on the above embodiment 1, in order to increase the structural strength of the intermediate frame 2, the following settings are now adopted.

[0037] See Figures 1-4In the above embodiment, ribs 4 are fixed around the middle frame 2. The surface of the ribs 4 is hollowed out. The ribs 4 increase the structural strength of the middle frame 2 and play the role of diagonal bracing and diagonal tension, reducing the occurrence of bending deformation of the middle frame 2. At the same time, since the surface of the ribs 4 is hollowed out, the weight of the ribs 4 is reduced while ensuring the strength of diagonal bracing and diagonal tension, thus reducing resource consumption.

[0038] The implementation principle of this utility model is as follows: First, before pouring the concrete foundation 1, the workers tie the vertical reinforcement 7 and the grid reinforcement 12 together with the steel bars inside the concrete foundation 1. Then, the workers place the intermediate frame 2 from top to bottom and support it above the concrete foundation 1 with some items. Since the bottom of the limiting hole 9 is frustum-shaped with an inclined surface, it is convenient for the vertical reinforcement 7 to pass through the limiting plate 8 through the limiting hole 9. Then, the workers pour concrete below the intermediate frame 2 and from the top of the intermediate frame 2 into the intermediate frame 2. At this time, the setting of the limiting plate 8 and the limiting hole 9 prevents the vertical reinforcement 7 from shifting and affecting the stress. After the concrete solidifies, the intermediate frame 2 is firmly fixed to the concrete foundation 1. At the same time, the vertical reinforcement 7 bears the force, effectively preventing the intermediate frame 2 from overturning or shifting. The concrete adheres to the perimeter of the gripping frame 10. Since the gripping frame 10 has a V-shaped cross section, it resembles a barb. When the intermediate frame 2 is subjected to an upward force, it can grip the concrete foundation 1 through the gripping frame 10 and the grid reinforcement 12, further preventing the intermediate frame 2 from overturning. Meanwhile, the horizontal support plate 11 increases the structural strength of the gripping frame 10 and reduces the phenomenon of the gripping frame 10 bending inward.

[0039] After the intermediate frame 2 and the concrete foundation 1 are completed, the workers remove the bottom support of the intermediate frame 2. Then, the workers can insert the crossbeams 5 from both sides, the outer surface and the back of the intermediate frame 2. The crossbeams 5 are then fastened by bolts through the mounting holes 3. The columns 6 are inserted from the top of the intermediate frame 2. The columns 6 are then fastened by bolts through the mounting holes 3. During this process, the ribs 4 are used to increase the structural strength of the intermediate frame 2, which acts as diagonal bracing and diagonal tension, reducing the occurrence of bending deformation of the intermediate frame 2. At the same time, since the surface of the ribs 4 is hollow, the weight of the ribs 4 is reduced while ensuring the strength of the diagonal bracing and diagonal tension, thus reducing resource consumption.
