Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a quickly constructed assembled foundation for earthquake relief. Background Art

[0002] At present, with the development and improvement of prefabricated technology, more and more buildings are using prefabricated structural systems, which greatly shortens the construction period. However, the current use of prefabricated technology has been limited to buildings above the ground, and there is no mature assembly technology for the foundation of the underground part. The vast majority of building foundation construction uses the traditional cast-in-place concrete method, but the process of cast-in-place concrete foundation is cumbersome, requiring leveling the site, tying steel cages, supporting formwork, etc., and the construction efficiency is low; when affected by natural disasters such as earthquakes, the traditional building foundation construction is restricted, resulting in the inability to quickly rebuild the building, which is not conducive to stabilizing the disaster situation. Summary of the invention

[0003] In view of this, the present invention discloses a quickly constructed assembled foundation for earthquake relief, which aims to solve the problem that when hit by natural disasters such as earthquakes, the traditional building foundation construction is restricted, resulting in the inability to quickly rebuild the building, which is not conducive to stabilizing the disaster situation.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] A rapidly erected assembled foundation for earthquake relief comprises a plurality of foundation beams, wherein connection foundations are arranged at the connection points of adjacent foundation beams, a cavity is provided inside the connection foundation, a plurality of ports facing the corresponding foundation beams are provided on the side walls of the cavity, a first coaxial annular groove is provided on the middle side wall of the port, a connecting sleeve is provided at the port, a coaxial annular plate is fixed to the circumference of the connecting sleeve, the annular plate extends into the first annular groove and is slidably connected thereto, a driving structure for driving the annular plate to move in any longitudinal direction is provided in the annular groove; a moving column is slidably connected in the connecting sleeve, and both ends of the foundation beams are detachably connected with fixed sleeves, and a ball joint connection is formed between the fixed sleeve and the corresponding moving column via a ball joint structure.

[0006] In this solution, the connection foundation is installed on the ground in sequence, and then the foundation beam is connected and fixed with the fixed sleeve to complete the assembly of the building foundation. The whole process is simple and fast, and can effectively speed up the reconstruction of disaster areas. Then, the annular plate is driven in any longitudinal direction by the driving structure, and the annular plate drives the connection sleeve to move synchronously, and the sliding of the moving column relative to the connection sleeve and the ball joint structure between the moving column and the fixed sleeve are used to adjust the spatial position of the two ends of the foundation beam, thereby eliminating the height difference, horizontal difference and angle difference of the foundation beam, thereby reducing the installation accuracy of the foundation beam and the connection foundation, effectively shortening the assembly time, and further speeding up the construction efficiency.

[0007] Furthermore, the top of the first annular groove passes through the connecting base upward, and the driving structure includes two rotating shafts which are rotatably connected to the two ends of the bottom wall of the first annular groove and are vertically arranged, the rotating shafts are threaded with connecting seats, and the top of the connecting seat is detachably connected to a hydraulic cylinder for pushing the annular plate to move horizontally, a plurality of connecting holes are provided on both sides of the annular plate, and connecting rods slidably connected to the connecting holes are fixed on the connecting seat; a plurality of sliding grooves are provided on both sides of the connecting rod, and a plurality of limit pins are slidably connected in the sliding grooves, and a reset spring is fixed between the limit pin and the sliding groove, and the end of the limit pin is arc-shaped; two rows of grouting grooves symmetrically arranged about the connecting rod are provided on the upper end of the annular plate, and the ends of the limit pins extend into the corresponding grouting grooves.

[0008] In this scheme, the connecting seat is driven to move up and down by synchronously driving the rotating shaft in the first annular groove to rotate, and then the annular plate is driven to move vertically through the connecting rod, and the annular plate is driven to move left and right relative to the connecting rod in cooperation with the hydraulic cylinder, so as to achieve the purpose of driving the annular plate in any longitudinal direction; and then the hydraulic cylinder is disassembled for recycling. In addition, the threaded connection between the rotating shaft and the connecting seat can be easily self-locked under the action of friction, and when the annular plate moves left and right relative to the connecting rod under the action of the hydraulic cylinder, the annular plate uses the arc-shaped end of the limit pin to squeeze the limit pin back into the slide groove, so that the annular plate can move left and right relative to the connecting rod; when the hydraulic cylinder is disassembled, the limit pin is reinserted into the grouting groove under the action of the reset spring, and the annular plate is horizontally locked without external force; after the adjustment is completed, concrete is injected into the grouting groove and the first annular groove, and after the concrete solidifies, the fixation of the annular plate is strengthened to prevent the movement of the annular plate from causing the foundation beam to deviate, affecting the safety of the building.

[0009] Furthermore, the ball joint structure includes a connecting ball fixed to the end of the fixed sleeve and a spherical cavity opened at the end of the movable column for accommodating the connecting ball, a plurality of limit holes are opened on the peripheral side of the connecting ball, a plurality of adjustment grooves are opened on the peripheral side of the movable column toward the center of the spherical cavity, a limit rod with an arc-shaped end is slidably connected in the adjustment groove, the same return spring is arranged between the limit rod and the adjustment groove, and a limit structure for limiting the movement of the limit rod is arranged on the movable column.

[0010] In this solution, when the foundation beam needs to be adjusted, the restriction of the limiting structure on the limiting rod is released. At this time, the connecting ball can completely squeeze the limiting rod back into the adjustment groove when it is deflected, so that the connecting ball can deflect freely; when the adjustment is completed, the limiting structure restricts the limiting rod, so that the connecting ball cannot completely squeeze the limiting rod back into the adjustment groove, thereby restricting the rotation of the connecting ball in the spherical cavity, thereby achieving the purpose of strengthening the connection strength between the connecting beam and the movable column.

[0011] Furthermore, the limiting structure includes a second annular groove opened on the circumferential side of the movable column and coaxial with the axis, one end of the limiting rod extends into the second annular groove, an annular limiting seat is rotatably connected in the second annular groove, and a plurality of grooves for accommodating the limiting rod are opened on the inner wall of the limiting seat, and the side walls of the grooves are arc-shaped.

[0012] When it is necessary to release the restriction of the limit structure on the limit rod, it is only necessary to rotate the limit seat so that the groove on the limit column is opposite to the limit rod, so that the limit rod can return to the adjustment groove after completion; when it is necessary to limit the limit rod, the limit seat is rotated in the opposite direction so that the inner wall of the limit seat is against the limit rod, so that the end of the limit rod can remain inserted into the limit hole, thereby limiting the deflection of the connecting ball.

[0013] Furthermore, a plurality of truncated cone-shaped anti-pullout structures are arranged on one end of the movable column away from the foundation beam.

[0014] Furthermore, a limiting protrusion for disengagement of the moving column is arranged in the connecting sleeve.

[0015] Furthermore, a latch for locking the moving column is provided on the connecting sleeve.

DETAILED DESCRIPTION

[0023] like Figures 1 to 4 As shown:

[0024] A fast-built assembled foundation for earthquake relief comprises a plurality of foundation beams 1. Connection foundations 2 are arranged at the connection points of adjacent foundation beams 1. A cavity is provided inside the connection foundation 2. A plurality of ports facing the corresponding foundation beams 1 are provided on the side walls of the cavity. A first coaxial annular groove is provided on the side wall in the middle of the port. A connecting sleeve 3 is provided at the port. A coaxial annular plate 4 is fixed to the circumference of the connecting sleeve 3. The annular plate 4 extends into the first annular groove and is slidably connected thereto. A driving structure for driving the annular plate 4 to move in any longitudinal direction is provided in the annular groove. A movable column 5 is slidably connected in the connecting sleeve 3. Both ends of the foundation beams 1 are detachably connected with fixed sleeves 6. A ball joint connection is formed between the fixed sleeve 6 and the corresponding movable column 5 via a ball joint structure.

[0025] In this solution, the connection foundation 2 is installed on the ground in sequence, and then the foundation beam 1 is connected and fixed with the fixed sleeve 6 to complete the assembly of the building foundation. The whole process is simple and fast, and can effectively speed up the reconstruction of disaster areas. Then, the annular plate 4 is driven in any longitudinal direction by the driving structure, and the annular plate 4 drives the connection sleeve 3 to move synchronously, and cooperates with the sliding of the moving column 5 relative to the connection sleeve 3 and the ball joint structure between the moving column 5 and the fixed sleeve 6 to adjust the spatial position of the two ends of the foundation beam 1, thereby eliminating the height difference, horizontal difference and angle difference of the foundation beam 1, thereby reducing the installation accuracy of the foundation beam 1 and the connection foundation 2, effectively shortening the assembly time, and further speeding up the construction efficiency.

[0026] In this embodiment, the top of the first annular groove passes through the connection base 2 upward, and the driving structure includes two rotating shafts 7 which are rotatably connected to the two ends of the bottom wall of the first annular groove and are vertically arranged. The rotating shafts 7 are threadedly connected with connecting seats 8, and the top of the connecting seats 8 is detachably connected with a hydraulic cylinder for pushing the annular plate 4 to move horizontally. A number of connecting holes are provided on both sides of the annular plate 4, and connecting rods 9 slidably connected to the connecting holes are fixed on the connecting seats 8; a number of sliding grooves are provided on both sides of the connecting rod 9, and a number of limit pins 10 are slidably connected in the sliding grooves, and a reset spring 11 is fixed between the limit pin 10 and the sliding groove, and the end of the limit pin 10 is arc-shaped; two rows of grouting grooves symmetrically arranged about the connecting rod 9 are provided on the upper end of the annular plate 4, and the ends of the limit pins 10 extend into the corresponding grouting grooves.

[0027] In this scheme, the connecting seat 8 is driven to move up and down by synchronously driving the rotating shaft 7 in the first annular groove to rotate, and then the annular plate 4 is driven to move vertically through the connecting rod 9, and the annular plate 4 is driven to move left and right relative to the connecting rod 9 by the hydraulic cylinder, so as to achieve the purpose of driving the annular plate 4 in any longitudinal direction; and then the hydraulic cylinder is disassembled for recycling. In addition, the threaded connection between the rotating shaft 7 and the connecting seat 8 can be easily self-locked under the action of friction, and when the annular plate 4 moves left and right relative to the connecting rod 9 under the action of the hydraulic cylinder, the annular plate 4 uses the arc-shaped end of the limit pin 10 to squeeze the limit pin 10 back into the slide groove, so that the annular plate 4 can move left and right relative to the connecting rod 9; when the hydraulic cylinder is disassembled, the limit pin 10 is reinserted into the grouting groove under the action of the reset spring 11, and the annular plate 4 is horizontally locked without external force; after the adjustment is completed, concrete is injected into the grouting groove and the first annular groove, and after the concrete solidifies, the fixation of the annular plate 4 is strengthened to prevent the movement of the annular plate 4 from causing the foundation beam 1 to deviate, affecting the safety of the building.

[0028] In this embodiment, the ball joint structure includes a connecting ball 12 fixed to the end of the fixed sleeve 6 and a spherical cavity opened at the end of the movable column 5 for accommodating the connecting ball 12, a plurality of limit holes 13 are opened on the peripheral side of the connecting ball 12, a plurality of adjustment grooves facing the center of the spherical cavity are opened on the peripheral side of the movable column 5, a limit rod 14 with an arc-shaped end is slidably connected in the adjustment groove, the same reset spring 11 is arranged between the limit rod 14 and the adjustment groove, and a limit structure for limiting the movement of the limit rod 14 is arranged on the movable column 5.

[0029] In this solution, when the foundation beam 1 needs to be adjusted, the restriction of the limiting structure on the limiting rod 14 is released. At this time, when the connecting ball 12 is deflected, the limiting rod 14 can be completely squeezed back into the adjustment groove, so that the connecting ball 12 can deflect freely; when the adjustment is completed, the limiting structure limits the limiting rod 14, so that the connecting ball 12 cannot completely squeeze the limiting rod 14 back into the adjustment groove, thereby limiting the rotation of the connecting ball 12 in the spherical cavity, thereby achieving the purpose of strengthening the connection strength between the connecting beam and the movable column 5.

[0030] In this embodiment, the limiting structure includes a second annular groove which is opened on the side of the movable column 5 and is coaxial with the axis. One end of the limiting rod 14 extends into the second annular groove. An annular limiting seat 15 is rotatably connected in the second annular groove. The inner wall of the limiting seat 15 is provided with a plurality of grooves 16 for accommodating the limiting rod 14. The side walls of the grooves 16 are arc-shaped.

[0031] When it is necessary to release the restriction of the limiting structure on the limiting rod 14, it is only necessary to rotate the limiting seat 15 so that the groove 16 on the limiting column is opposite to the limiting rod 14, so that the limiting rod 14 can return to the adjustment groove after completion; when it is necessary to limit the limiting rod 14, the limiting seat 15 is rotated in the opposite direction so that the inner wall of the limiting seat 15 is against the limiting rod 14, so that the end of the limiting rod 14 can remain inserted into the limiting hole 13, thereby limiting the deflection of the connecting ball 12.

[0032] In this embodiment, a plurality of truncated cone-shaped anti-pullout structures 17 are provided on the end of the movable column 5 away from the foundation beam 1, and a plurality of injection ports (not shown) connected to adjacent grouting grooves are opened on the surface of the annular plate 4 away from the foundation beam 1.

[0033] The injection port is used to allow concrete to flow from the grouting groove into the cavity and fill the interior of the connecting sleeve 3. The solidified concrete combined with the anti-pullout structure 17 can effectively prevent the movable column 5 from sliding relative to the connecting sleeve 3, and no additional template is required.

[0034] In this embodiment, a limiting protrusion (not shown in the figure) is provided in the connecting sleeve 3 , and the limiting protrusion is used to prevent the moving column 5 from being separated from the connecting sleeve 3 .

[0035] In this embodiment, a pin (not shown in the figure) for locking the movable column 5 is provided on the connecting sleeve 3. The movable column 5 is initially fixed by the pin to prevent the movable column 5 from sliding relative to the connecting sleeve 3 when the concrete solidifies, thereby affecting the connection strength between the foundation beam 1 and the connecting foundation 2.

[0036] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
