Description

Technical Field

[0001] The invention belongs to the technical field of assembled buildings, and in particular relates to a prefabricated concrete assembled house body. Background Art

[0002] Precast concrete refers to prefabricated components produced and processed in factories. They only need to be assembled on site and follow the subsequent steps according to the process flow. This working method greatly reduces the construction period. It includes but is not limited to precast concrete walls, stairs, floor slabs and other precast components. Buildings composed of these components are generally referred to as prefabricated houses.

[0003] During the stair installation process, the precast concrete stair components are usually hoisted to the designated location by a crane, and the technicians align the positioning holes of the stairs and the floor slabs. The crane uses steel cables to hoist the stairs. This step will increase the time spent on the crane to hoist the stairs, and manual calibration takes a lot of effort. The crane also needs to perform other hoisting work at the construction site, which will slow down the overall construction progress and reduce construction efficiency. For this reason, we provide a precast concrete assembled house. Summary of the invention

[0010] The end of the sleeve is provided with an opening and communicates with the interior of the second hydraulic cylinder, the interior of the second hydraulic cylinder is filled with hydraulic oil, and a cavity is formed between the guide rod and the second sealing plate and is filled with hydraulic oil;

[0011] The hydraulic mechanism controls the lifting and lowering of the support box through the support assembly.

[0012] Preferably, the positioning assembly also includes a tension spring, and the lower ends of the two support plates are elastically connected by the tension spring. Every two reducers form a group, and each group of reducers is respectively arranged on both sides of hydraulic cylinder 2. The telescopic end of hydraulic cylinder 2 is "L"-shaped, and the opposite surfaces of the telescopic ends of the two hydraulic cylinders are respectively bearing-mounted with a positioning plate.

[0013] Preferably, the hydraulic mechanism includes an oil box fixedly mounted on the top of the base, a threaded rod is installed on the top bearing of the oil box, a pressure plate located inside the oil box is provided on the outer threaded sleeve of the threaded rod, an oil groove is opened inside the base, and the oil groove is connected to the inside of the oil box.

[0014] Preferably, the pressure plate is adapted to the interior of the oil box, and the space between the bottom of the pressure plate and the interior of the oil box is filled with hydraulic oil.

[0015] Preferably, each of the supporting assemblies comprises a hydraulic cylinder 1 fixedly mounted on the top of the base and a telescopic plate 1 hinged to the top of the base, the telescopic end of the telescopic plate 1 being hinged with a pad, the outer peripheral sleeve of the hydraulic cylinder 1 being provided with a limit sleeve, the top of the limit sleeve being connected to the top of the telescopic end of the hydraulic cylinder 1 through telescopic plate 2, the outer side of the limit sleeve being movably connected to the fixed end of the telescopic plate 1 through a spring telescopic rod, and the telescopic end of the hydraulic cylinder 1 being hinged to the support box through a limit wheel.

[0016] Preferably, the support assembly further comprises limiting plates arranged on two opposite surfaces of the top of the limiting sleeve, a plurality of slots are formed on the outer circumference of the limiting wheel, the limiting plate is arc-shaped and a protrusion matched with the slots is arranged on the inner side.

[0017] Preferably, the interior of each hydraulic cylinder 1 is connected to the interior of the oil box through an oil groove, and the interior of the hydraulic cylinder 1 is filled with hydraulic oil.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention cooperates with structures such as a positioning component and a hydraulic mechanism, so that the concrete stair prefabricated part descends and the rubber plate compresses the two supporting plates. The lower end of the hydraulic cylinder squeezes the hydraulic oil inside the third support plate into the telescopic rod and forces it to drive the guide rod to extend. The guide rod drives the hydraulic oil between the third support plate and the second sealing plate to move. After the second sealing plate is tightly attached to the partition, the oil pressure drives the first sealing plate to squeeze the air between the first sealing plate and the second sealing plate through the metal rod. Since the air is compressible, the telescopic end of the second hydraulic cylinder will move slowly and prevent the telescopic end of the second hydraulic cylinder from still moving during the movement of the concrete stair prefabricated part, thereby damaging the concrete stair prefabricated part and the device. After the concrete stair prefabricated part is attached to the top of the rubber plate and is fixed, the crane can directly detach from the concrete stair prefabricated part, and the positioning assembly and the concrete stair prefabricated part can be lowered to a suitable installation position by driving the supporting assembly through the hydraulic mechanism. Further, the time spent on installing the stairs by the crane is reduced, and the labor of manually moving the concrete stair prefabricated part and aligning it with the installation position is reduced.

[0020] The present invention cooperates with structures such as a positioning component and a supporting component, rotates the threaded rod, forces the pressure plate to descend, and squeezes the hydraulic oil into the interior of the two hydraulic cylinders through the oil tank. The hydraulic cylinder drives the positioning component to rise and fix the position of the concrete stair prefabricated component. The threaded rod is rotated in the opposite direction, and the hydraulic oil can quickly lower the height of the positioning component. The lower end of the concrete stair prefabricated component will preferentially be located at a designated position on the floor slab and be in a fixed state. The threaded rod is rotated in the opposite direction again, so that the hydraulic oil in the other hydraulic cylinder can be extracted and the height of the other positioning component can be lowered until the other end of the concrete stair prefabricated component is close to the installation position. Further, the cost of manual labor is reduced without reducing the efficiency of the installation of the concrete stair prefabricated components.

[0021] The present invention cooperates with structures such as support components and concrete stair precast parts. Before the concrete stair precast parts are hoisted, it is necessary to manually pull the telescopic plate one and make the pad close to the bottom of the floor installation position. This ensures that the concrete stair precast parts will also be located at the installation position after being fixed by the positioning component, reducing the time and energy of workers in translating the concrete stair precast parts. Subsequently, the two telescopic plates one are pushed in turn close to the outside of the hydraulic cylinder one, and the pad is separated from the bottom of the floor. The telescopic plate one pushes the limit sleeve to rise through the spring telescopic rod, while compressing the telescopic plate two and driving the limit plate to rise. The protrusions on the inner wall of the limit plate are then close to the notches on the outer periphery of the limit wheel, thereby preventing the support box from moving through the hinge point of the telescopic end of the hydraulic cylinder one, further limiting the position of the positioning component, and the positioning component will not be damaged due to swinging.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 8 As shown, the present invention provides a prefabricated concrete assembled house body, including a concrete staircase prefabricated part 1 and a base 2, and also includes;

[0033] A support assembly 4 is respectively arranged at two ends of the top of the base 2;

[0034] A positioning assembly 5 is respectively provided on the top of each supporting assembly 4;

[0035] The positioning assembly 5 includes a support box 51 hinged to the top of the support assembly 4, and two mutually intersecting support plates 55 are hinged on the top of the support box 51. A rubber plate 54 is slidably mounted on one end of the two support plates 55. Two hydraulic cylinders 3 56 are symmetrically arranged inside the support box 51. The interior of the hydraulic cylinders 3 56 is filled with hydraulic oil. The other ends of the two support plates 55 are respectively hinged to the side of each hydraulic cylinder 3 56. Two symmetrical hydraulic cylinders 2 52 are arranged inside the support box 51. The interior of each hydraulic cylinder 3 56 is connected to two telescopic rods 57. The telescopic ends of each telescopic rod 57 are respectively fixedly connected to a reducer 58.

[0036] Each reducer 58 includes a sleeve 581 disposed inside the fixed end of the second hydraulic cylinder 52, a guide rod 584 connected to the telescopic end of the telescopic rod 57 is movably disposed inside the sleeve 581, a sealing plate 1 582 is movably disposed inside the sleeve 581, a sealing plate 2 583 is movably clamped on one side of the sealing plate 1 582 close to the guide rod 584 through a metal rod, and a partition for separating the sealing plate 2 583 and the guide rod 584 is disposed inside the sleeve 581, and a hole is disposed on the partition;

[0037] The end of the sleeve 581 is provided with an opening and communicates with the interior of the second hydraulic cylinder 52. The interior of the second hydraulic cylinder 52 is filled with hydraulic oil. A cavity is formed between the guide rod 584 and the second sealing plate 583 and is filled with hydraulic oil.

[0038] The hydraulic mechanism 3 controls the lifting and lowering of the support box 51 through the support assembly 4 .

[0039] The above scheme is adopted: the support assembly 4 is controlled by the hydraulic mechanism 3 to lift the positioning assembly 5 to a suitable position, and the concrete stair prefabricated component 1 is hoisted to the top of the support box 51 by a crane, and then slowly lowered so that the bottom of the concrete stair prefabricated component 1 contacts and presses the rubber plate 54.

[0040] Since the support box 51 is hinged to the support assembly 4, the rubber sheet 54 will gradually fit the bottom of the concrete staircase prefabricated component 1 during the descent of the concrete staircase prefabricated component 1, thereby preventing deviations in the subsequent installation of the concrete staircase prefabricated component 1, thereby ensuring installation accuracy;

[0041] The rubber plate 54 presses the upper ends of the two support plates 55. Since the two support plates 55 are cross-mounted and hinged on the top of the support box 51, the lower ends of the two support plates 55 will move away from each other, thereby squeezing the hydraulic oil in the hydraulic cylinder three 56 into the telescopic rod 57 and forcing it to drive the guide rod 584 to extend. The guide rod 584 drives the hydraulic oil between it and the sealing plate two 583 to move. When the sealing plate two 583 is close to the partition, the metal rod will penetrate the hole on the partition, thereby causing the oil pressure to drive the sealing plate one 582 to move through the metal rod. At the same time, the air between the sealing plate two 583 and the sealing plate one 582 is squeezed. Since the air is compressible, the concrete stair prefabricated part 1 completely falls into the top of the support box 51 and can no longer squeeze the rubber plate 54 to move. The telescopic end of the hydraulic cylinder two 52 will move slowly, thereby preventing the telescopic end of the hydraulic cylinder two 52 from still moving during the squeezing of the rubber plate 54 by the concrete stair prefabricated part 1, thereby damaging the concrete stair prefabricated part 1 and the device.

[0042] After the concrete stair prefabricated component 1 is attached to the top of the rubber sheet 54 and fixed, the crane can directly detach from the concrete stair prefabricated component 1, and the support component 4 can be driven by the hydraulic mechanism 3 to lower the positioning component 5 and the concrete stair prefabricated component 1 to a suitable installation position, further reducing the time spent on the crane to install the stairs, and at the same time reducing the labor of manually moving the concrete stair prefabricated component 1 and aligning it to the installation position.

[0043] like Figure 1-Figure 5 As shown, the positioning assembly 5 also includes a tension spring 59, and the lower ends of the two support plates 55 are elastically connected by the tension spring 59. Every two reducers 58 form a group, and each group of reducers 58 is respectively arranged on both sides of the hydraulic cylinder 2 52. The telescopic end of the hydraulic cylinder 2 52 is "L" shaped, and the opposite surfaces of the telescopic ends of the two hydraulic cylinders 2 52 are respectively bearing-mounted with a positioning plate 53.

[0044] With the above solution, after the concrete stair prefabricated part 1 is separated from the rubber plate 54, the tension spring 59 will quickly pull the lower ends of the two support plates 55 together, thereby merging the two upper ends thereof at the same time, and lifting the rubber plate 54 to the initial position, so that the next work can still be carried out smoothly, while also reducing the labor and energy of manual resetting;

[0045] When the concrete stair prefabricated component 1 is completely attached and presses the rubber plate 54 until it can no longer be pressed, the telescopic end of the hydraulic cylinder 2 52 clamps the two sides of the concrete stair prefabricated component 1. It should be noted that the positioning plate 53 will also fit the top of the concrete stair prefabricated component 1, thereby preventing the concrete stair prefabricated component 1 from deviating or sliding in position.

[0046] like Figure 1-Figure 3 , Figure 7 and Figure 8As shown, the hydraulic mechanism 3 includes an oil box 31 fixed on the top of the base 2, a threaded rod 32 is installed on the top bearing of the oil box 31, a pressure plate 33 located inside the oil box 31 is threadedly sleeved on the outer periphery of the threaded rod 32, and an oil groove 34 is opened inside the base 2, and the oil groove 34 is connected to the inside of the oil box 31.

[0047] The pressure plate 33 is adapted to the interior of the oil box 31 , and the space between the bottom of the pressure plate 33 and the interior of the oil box 31 is filled with hydraulic oil.

[0048] Each supporting assembly 4 includes a hydraulic cylinder 41 fixed to the top of the base 2 and a telescopic plate 44 hinged to the top of the base 2, the telescopic end of the telescopic plate 44 is hinged with a pad 45, the outer peripheral sleeve of the hydraulic cylinder 41 is provided with a limit sleeve 42, the top of the limit sleeve 42 is connected to the top of the telescopic end of the hydraulic cylinder 41 through the telescopic plate 46, the outer side of the limit sleeve 42 is movably connected to the fixed end of the telescopic plate 44 through a spring telescopic rod 43, and the telescopic end of the hydraulic cylinder 41 is hinged to the support box 51 through a limit wheel 47.

[0049] The interior of each hydraulic cylinder 1 41 is connected to the interior of the oil box 31 through the oil groove 34, and the interior of the hydraulic cylinder 1 41 is filled with hydraulic oil.

[0050] The above scheme is adopted: rotating the threaded rod 32 can force the pressing plate 33 to descend and squeeze the hydraulic oil through the oil groove 34 to enter the inside of the two hydraulic cylinders 41 respectively. At this time, the hydraulic cylinder 41 stretches and drives the positioning assembly 5 to rise. Since the concrete stair prefabricated component 1 is tilted during the hoisting and installation process, after one of the positioning assemblies 5 fixes one end of the concrete stair prefabricated component 1, the threaded rod 32 is continuously rotated, so that the hydraulic oil can continue to enter the other hydraulic cylinder 41 and force the other positioning assembly 5 to rise and fix the position of the concrete stair prefabricated component 1. At this time, the crane can be detached from the concrete stair prefabricated component 1, further shortening the working time of the crane and accelerating the overall construction progress of the project;

[0051] When the two positioning components 5 completely fix the position of the concrete stair prefabricated component 1, the threaded rod 32 is rotated in the opposite direction, and the hydraulic oil can be quickly released from the hydraulic cylinder 41, and the height of the positioning component 5 at the lower end is lowered, so that one end of the concrete stair prefabricated component 1 is preferentially located at the designated position on the floor slab and is in a fixed state;

[0052] Rotating the threaded rod 32 in the opposite direction again can extract the hydraulic oil in another hydraulic cylinder 41 and lower the height of another positioning assembly 5 until the other end of the concrete stair prefabricated component 1 is close to the installation position, further reducing the cost of manual labor without reducing the efficiency of the installation of the concrete stair prefabricated component 1.

[0053] like Figure 7 and Figure 8 As shown, the support assembly 4 also includes limiting plates 48 arranged on two opposite surfaces of the top of the limiting sleeve 42, and a plurality of slots are opened on the outer periphery of the limiting wheel 47. The limiting plate 48 is arc-shaped and has protrusions matched with the slots arranged on the inner side.

[0054] Adopting the above scheme: before the concrete stair prefabricated component 1 is hoisted, it is necessary to manually pull the telescopic plate 44 and make the pad 45 close to the bottom of the floor installation position, so that after the concrete stair prefabricated component 1 is fixed by the positioning component 5, it will also be located at the installation position, reducing the time and energy of the workers to translate the concrete stair prefabricated component 1. When the concrete stair prefabricated component 1 is lowered by the support component 4, the bottom of the concrete stair prefabricated component 1 will be preferentially located on the top of the two pads 45, and then confirm again whether there is any deviation in the installation position;

[0055] Then, the two telescopic plates 1 44 are pushed in sequence to approach the outer side of the hydraulic cylinder 1 41, and the pad 45 is separated from the bottom of the floor slab. The telescopic plate 1 44 pushes the limit sleeve 42 upward through the spring telescopic rod 43, and at the same time compresses the telescopic plate 2 46 and drives the limit plate 48 to rise. The protrusions on the inner wall of the limit plate 48 then cling to the notches on the outer periphery of the limit wheel 47 and fix its position, thereby preventing the support box 51 from moving through the hinge point of the telescopic end of the hydraulic cylinder 1 41, so that when the device is not working, the positioning assembly 5 will not be damaged due to swinging;

[0056] The working principle and use process of the present invention:

[0057] Manually pull the telescopic plate 44 and make the pad 45 close to the bottom of the floor installation position, rotate the threaded rod 32 and force the pressing plate 33 to move down to squeeze the hydraulic oil, which enters the inside of the two hydraulic cylinders 41 through the oil groove 34 respectively, and the hydraulic cylinder 41 stretches and drives the positioning assembly 5 to rise to the specified position;

[0058] Use a crane to hoist the concrete stair prefabricated component 1 to the top of the support box 51, and then slowly descend so that the bottom of the concrete stair prefabricated component 1 contacts and presses the rubber plate 54. The rubber plate 54 presses the upper ends of the two support plates 55, and the two lower ends thereof move away from each other, thereby squeezing the hydraulic oil inside the hydraulic cylinder three 56 into the telescopic rod 57 and forcing it to drive the guide rod 584 to extend. The guide rod 584 drives the hydraulic oil between it and the sealing plate two 583 to move. When the sealing plate two 583 is close to the partition, the metal rod will penetrate the hole on the partition, and then the oil pressure drives the sealing plate one 582 to move through the metal rod. At the same time, the air between the sealing plate two 583 and the sealing plate one 582 is squeezed. Due to the compressibility of air, the concrete stair prefabricated component 1 completely falls into the top of the support box 51 and can no longer squeeze the rubber plate 54 to move. At this time, the telescopic end of the hydraulic cylinder two 52 will slowly move and clamp the concrete stair prefabricated component 1.

[0059] When the two positioning components 5 completely fix the position of the concrete staircase prefabricated component 1, the threaded rod 32 is rotated in the opposite direction, and the hydraulic oil can quickly reduce the height of the positioning component 5 at the lower end, so that one end of the concrete staircase prefabricated component 1 is preferentially located at the designated position on the floor slab and is in a fixed state;

[0060] Rotating the threaded rod 32 in the opposite direction again can draw out the hydraulic oil in the other hydraulic cylinder 41 and lower the height of the other positioning assembly 5 until the other end of the concrete staircase prefabricated component 1 is close to the installation position;

[0061] Then, the two telescopic plates 44 are pushed in sequence to the outside of the hydraulic cylinder 41, and the pad 45 is separated from the bottom of the floor. The telescopic plate 44 pushes the limit sleeve 42 to rise through the spring telescopic rod 43, and at the same time compresses the telescopic plate 46 and drives the limit plate 48 to rise. The protrusions on the inner wall of the limit plate 48 then cling to the grooves on the outer periphery of the limit wheel 47 and fix its position.

[0062] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
